看第二代iPod touch运行"iOS 7"
新浪科技讯 北京时间1月1日上午消息,尽管苹果的第一代和第二代iPhone和iPod Touch已经过时,但黑客组织"whited00r"仍试图将iOS的许多最新功能,例如"控制中心"加入这些很老的设备。
whited00r因开发同名固件而知名。这是一个基于iOS 3.1.3进行大量订制的固件版本,在苹果公司官方不再支持的设备上模拟新版iOS的界面和功能。这一固件支持的设备包括第一代iPhone、iPhone 3G,以及第一代和第二代iPod Touch。
最新版的whited00r 7模拟了iOS 7的许多标准功能,例如控制中心,以及iOS 7风格的摄像头应用和多任务视图。该版本固件的推送通知模拟了iOS最新的"窗帘式设计",而iOS以往的语音控制功能也得到了整合。iOS 7的大部分其他视觉效果,例如扁平化图标和新的菜单设计也在whited00r 7中得到实现。
在使用whited00r固件的过程中,如果用户发现某些功能的性能很差,那么可以在设置菜单中单独激活或关闭这些功能。在已支持的设备上安装whited00r固件只需3步。在使用RedsnOw进行越狱后,用户可以通过iTunes加载whited00r的订制固件,并重启设备完成安装。
whited00r项目最初于2010年启动,当时是为了在只能运行iOS 3的设备上添加iOS 4的功能。自那时以来,该版本固件的开发一直在进行。根据开源代码服务SourceForge的数据,whited00r 7固件自发布以来已被下载数十万次。(维金)

新浪科技讯 北京时间1月1日凌晨消息,据新闻网站The Information周二报道,索尼正考虑在2014年中推出一款Windows Phone手机。
如果这一报道属实,则意味着索尼将打破对谷歌Android操作系统的"忠诚度",同时令诺基亚在Windows Phone市场上面临新的竞争对手。据报道称,双方已进行了多次磋商,且索尼已设计出了原型手机。The Information网站还报道称,索尼未来将会推出的任何Windows Phone手机都将冠以Vaio品牌名。
据报道,微软收购诺基亚旗下设备部门的交易并未打消索尼推出Windows Phone手机的念头;即使是在这项并购交易宣布后,相关谈判也仍在继续进行。但报道同时指出,目前双方仍未达成最终协议;如果微软和索尼在授权费用、预装软件及其他问题上无法达成一致,则这项计划也可能会中途流产。
业界人士指出,对微软和索尼来说,在移动领域中达成联盟合作关系并非新鲜事。从较早的原型机来看,索尼此前就已考虑采用Windows Phone系统。
就Windows Phone硬件而言,目前诺基亚Lumia智能手机相对于微软的其他合作伙伴而言占据着压倒性的优势,但部分原因是这个市场上缺少真正的竞争。三星和HTC均推出了Windows Phone手机,但这两家公司都仍把重点放在开发Android手机上。
业界人士称,对微软来说,如果想要Windows Phone手机取得成功,则该公司必须找到其他愿意大力推进该平台发展的厂商。据此前报道称,微软目前还在与中兴通讯展开谈判,希望由后者生产面向美国、中国和欧洲市场上的低端Windows Phone手机。(唐风)

苹果近日发布的一份图表显示,iOS 7 在苹果所有 iOS 设备中的占比已高达 78%,较本月初的 74% 有了进一步提升。
数据基于 12 月 29 日前 7 天访问 App Store 的设备情况
iOS 6 的份额从月初的 22% 降至当前的 18%,更早版本的 iOS 份额维持在 4% 不变。
iOS 7 正式版于 9 月 19 日正式推送,除了老用户升级系统外,新 iPhone 以及新 iPad 的热销都为 iOS 7 的普及做出了巨大贡献。iOS 6 依然"顽强抵抗"则主要是部分旧机型不支持 iOS 7 或是用户不愿升级系统。
尽管面世以来饱受非议,但 iOS 7 份额的进一步攀升,意味着更多用户已经接纳或习惯了这一系统。目前 App Store 里一些 app 仅支持 iOS 7 而不再向下兼容,这也让部分用户迫于升级。

Vitamin E may delay decline in mild-to-moderate Alzheimer's disease

Dec. 31, 2013 — Difficulty with activities of daily living often affect Alzheimer's patients, which is estimated to affect as many as 5.1 million Americans. These issues are among the most taxing burdens of the disease for caregivers, which total about 5.4 million family members and friends. New research from the faculty of Icahn School of Medicine at Mount Sinai working with Veterans Administration Medical Centers suggests that alpha tocepherol, fat-soluble Vitamin E and antioxidant, may slow functional decline (problems with daily activities such as shopping, preparing meals, planning, and traveling) in patients with mild-to-moderate Alzheimer's disease and decrease caregiver burden. There was no added benefit for memory and cognitive testing with the vitamin.

The study is published online first in the Jan. 1 Journal of the American Medical Association.
"Since the cholinesterase inhibitors [galantamine, donepezil, rivastigmine], we have had very little to offer patients with mild-to-moderate dementia," said Mary Sano, PhD, trial co-investigator, and professor in the department of psychiatry, Icahn School of Medicine at Mount Sinai, and director of research at the James J. Peters Veteran's Administration Medical Center, Bronx, New York. "This trial showed that vitamin E delays progression of functional decline by 19% per year, which translates into 6.2 months benefit over placebo."
The finding is valuable because vitamin E is easy to purchase at local drugstores and it is also inexpensive. The clinical trial investigators believe it can be recommended as a treatment strategy, based on the double-blind randomized controlled trial.
The Veteran's Administration Cooperative Randomized Trial of Vitamin E and memantine in Alzheimer's Disease (TEAM-AD examined the effects of vitamin E 2,000 IU/d, 20 mg/d of memantine, the combination, or placebo on Alzheimer's Disease Cooperative Study/Activities of Daily Living (ADCS-ADL) Inventory Score. Cognitive, neuropsychiatric, functional, and caregiver measures were secondary outcomes. A group of 613 patients with mild to moderate Alzheimer's disease were in the study, which was launched in August 2007 and finished in September 2012 at 14 Veterans Affairs Medical Centers.
Dr. Sano previously led a study on vitamin E in patients with moderately severe Alzheimer's disease. She found that the vitamin slowed disease progression in this group of patients as well.

New studies give strong boost to binary-star formation theory
http://feeds.sciencedaily.com/~r/sciencedaily/~3/jDi5_dqnUcM/131231122141.htm
Dec 31st 2013, 17:21
Dec. 31, 2013 — Using the new capabilities of the upgraded Karl G. Jansky Very Large Array (VLA), scientists have discovered previously-unseen binary companions to a pair of very young protostars. The discovery gives strong support for one of the competing explanations for how double-star systems form.
Astronomers know that about half of all Sun-like stars are members of double or multiple-star systems, but have debated over how such systems are formed.
"The only way to resolve the debate is to observe very young stellar systems and catch them in the act of formation," said John Tobin, of the National Radio Astronomy Observatory (NRAO). "That's what we've done with the stars we observed, and we got valuable new clues from them," he added.
Their new clues support the idea that double-star systems form when a disk of gas and dust whirling around one young star fragments, forming another new star in orbit with the first. Young stars that still are gathering matter from their surroundings form such disks, along with jet-like outflows rapidly propelling material in narrow beams perpendicular to the disk.
When Tobin and an international team of astronomers studied gas-enshrouded young stars roughly 1,000 light-years from Earth, they found that two had previously-unseen companions in the plane where their disks would be expected, perpendicular to the direction of the outflows from the systems. One of the systems also clearly had a disk surrounding both young stars.
"This fits the theoretical model of companions forming from fragmentation in the disk," Tobin said. "This configuration would not be required by alternative explanations," he added.
The new observations add to a growing body of evidence supporting the disk-fragmentation idea. In 2006, a different VLA observing team found an orbiting pair of young stars, each of which was surrounded by a disk of material. The two disks, they found, were aligned with each other in the same plane. Last year, Tobin and his colleagues found a large circumstellar disk forming around a protostar in the initial phases of star formation. This showed that disks are present early in the star formation process, a necessity for binary pairs to form through disk fragmentation.
"Our new findings, combined with the earlier data, make disk fragmentation the strongest explanation for how close multiple star systems are formed," said Leslie Looney of NRAO and the University of Illinois.
"The increased sensitivity of the VLA, produced by a decade-long upgrade project completed in 2012, made the new discovery possible," Claire Chandler of NRAO said.
The new capability was particularly valuable at the VLA's highest frequency band, from 40-50 GHz, where dust in the disks surrounding young stars emits radio waves. The astronomers observed the young stars during 2012 with the VLA and with the Combined Array for Research in Millimeter-wave Astronomy (CARMA) in California.
Tobin, Chandler, and Looney were part of a research team of astronomers from the U.S., Mexico, and the Netherlands. The scientists published their findings in the Astrophysical Journal.

11月底的时候,雷军曾在微博上透露,在移动版(T+G)、联通版(W+G)发售之后,红米下一步就要朝电信版(C+G)迈进了,售价依然保持799元不变。
日前,有微博网友放出了电信版红米手机的谍照,从左上角的网络运营商显示来看,为"电信|移动",似乎预示着红米电信版快要来了。不过,我们在工信部网站上,尚未查到有关红米电信版的信息。但从之前雷军的口吻来看,应该很快了。
电信版红米与之前的移动版、联通版出了支持网络制式不同外,配置方面应该不会有变化,即采用4.7寸720p触摸屏,搭载1.5GHz MT6589T四核处理器,内置1GB RAM(4GB存储空间可扩展),提供800万主摄像头+130万前置摄像头,运行Android 4.2.2系统,电池容量是2000mAh。
如果红米电信版发布,你还会买吗?

据国外消息,此前曝光的Lumia630和Lumia635将不再具有诺基亚品牌,也就是说,在这两款手机之后,Lumia将正式归属于微软,Lumia与诺基亚开始脱离了关系。
据称,Lumia635是一款双卡Windows Phone手机,支持3G网络,Lumia635是单卡机型,支持4G LTE网络。

据曝光的两款手机截图也可以知道,两款手机将是搭载最新版的操作系统,底部已经集成了虚拟按键,并且上面的磁贴也都发生了些许变化,比如人脉磁贴的表现方式似乎已经可以调节了。
不 过目前还不能确定此后微软是否会将Lumia系列作为Windows Phone手机的品牌存在,只叫"Lumia630"或"Lumia635",还是 会叫"微软lumia630"和"微软lumia635"。此前微软曾经宣称过不会采用类似于"诺基亚LumiaXXX"的形式命名,所以后者应该不太可 能。

新浪科技讯 北京时间1月1日凌晨消息,中国知名企业家兼慈善家陈光标周二对《纽约时报》表示,他将带领一个投资者团体筹资10亿美元,寻求收购纽约时报公司(NYT)的大额股份或控股权。
陈光标在今天发表讲话时暗示有此计划。受此影响,纽约时报公司股价在纽约证券交易所[微博]的常规交易中一度触及五年新高,但随后转为下跌,收盘报15.88美元,跌幅为1.31%。今年截至目前为止,纽约时报公司的A类股股价已经上涨了86%左右。该公司曾在今年早些时候 称,其控股家族无意出售该公司。
陈光标在周二接受电话采访时表示,多年来他一直都考虑与纽约时报公司"合作",而最近他已说服两名商人帮助他筹集大约10亿美元资金,以便收购该公司的大额股份。按当前股价计算,纽约时报公司的市值为24亿美元左右。受股权结构的影响,该公司的控股权在很 大程度上归属于其B类股,而B类股的持有者则是阿道夫0奥兹(Adolph S.Ochs)的后代,他在1896年收购了这家公司。
陈光标表示:"如果我能完成这项与纽约时报公司之间的交易,那么就能带来更多正面的形象和影响,从而为世界和平做出贡献,让这个世界变得更好。而如果交易破裂,那么我将在美国市场上寻找另一家信誉良好且有影响力的媒体公司以实现这个目标。"
纽约时报公司最近几个季度的财报均表现良好,其发行量也有所增长,从而推动其股价上涨,但该公司仍在广告市场上面临困境。(文武/编译)

苹果电子书价格操纵案续:与监督员激战正酣
http://tech.163.com/13/1231/22/9HF5KMJS000915BD.html
Dec 31st 2013, 22:34
据国外媒体的报道,在今年早些时候的苹果电子书价格操纵案中,联邦法院法官丹尼斯·科特(Denise Cote)委任律师迈克尔·布罗姆维奇(Michael Bromwich)为本案的监督员,但随后苹果表示布鲁姆维奇所收取的费用高得离谱,并要求联邦法院终止其监督员的身份。
日前该事件进一步发酵,不过这次由布罗姆维奇首先发难,他表示在对苹果进行监察的过程中,后者对他们的工作非常不配合。在长达11页的法庭文件中,布鲁姆维奇反复指出苹果一直在试图阻挠他与苹果高层的对话,同时苹果也未能按照他的要求提供指定的文件。
目前苹果的律师和布罗姆维奇的发言人均拒绝就该事件发表评论。
在过去的几个月中,苹果与布罗姆维奇之间争执不断。苹果在11月曾公开指出布罗姆维奇在监察该公司的过程中采用了"过于自由和不恰当的方式",同时还强调布罗姆维奇的收费过高,两周的薪水高达13.8万美元,其中布罗姆维奇个人每小时的薪水达到了1100美元,其团队的薪水则为每小时1025美元,均高于当时的市场价格。
苹果因此在今年12月向科特法官提请终止布罗姆维奇对其的监察,科特法官曾在今年7月份裁定苹果存在与美国五大出版商相互勾结哄抬电子书价格的不法行为,但苹果随后表示不服,并计划提出上诉。
布罗姆维奇随后向美国司法部提出了继续对苹果进行监察的申请,而司法部在12月公布的一份文件中指出,终止布罗姆维奇对苹果的监察将会违背"通过公众关注来防止苹果出现更多的违反反托拉斯法的行为"的原则,所以决定让布罗姆维奇继续出任苹果电子书价格操纵案的监督员。
布罗姆维奇在本周一指出,在他以前监察过的三个组织中,从来没有一家拒绝或找借口延迟他所提出的与高层进行对话的要求,"苹果在这方面的表现大大不如我此前所监察过的三个组织,"布罗姆维奇介绍说。
布罗姆维奇提交的电子邮件内容显示,他与苹果的关系从一开始就处于僵持状态。他曾在一封发给苹果竞争法主管凯勒·安德尔(Kyle Andeer)的邮件中向后者详细描述了收费标准和监察流程,很显然,双方在许多地方都存在巨大差距。
"感谢您的回复,"布罗姆维奇在今年10月26日发给安德尔的一封邮件中说道,"不幸的是,我觉得您好像误解了我此前邮件的意思,现在不是我们双方讨价还价的时候。"不过安德尔随后的回复也相当干脆:"我对你给出的报价感到失望,这比市场价实在高得太多!"

Cloudy weather revealed on alien world

Dec. 31, 2013 — Weather forecasters on exoplanet GJ 1214b would have an easy job. Today's forecast: cloudy. Tomorrow: overcast. Extended outlook: more clouds.
A team of scientists led by researchers in the Department of Astronomy and Astrophysics at the University of Chicago report they have definitively characterized the atmosphere of a super-Earth class planet orbiting another star for the first time.
The scrutinized planet, which is known as GJ1214b, is classified as a super-Earth type planet because its mass is intermediate between those of Earth and Neptune. Recent searches for planets around other stars ("exoplanets") have shown that super-Earths like GJ 1214b are among the most common type of planets in the Milky Way galaxy. Because no such planets exist in our Solar System, the physical nature of super-Earths is largely unknown.
Previous studies of GJ 1214b yielded two possible interpretations of the planet's atmosphere. Its atmosphere could consist entirely of water vapor or some other type of heavy molecule, or it could contain high-altitude clouds that prevent the observation of what lies underneath.
But now a team of astronomers led by UChicago's Laura Kreidberg and Jacob Bean have detected clear evidence of clouds in the atmosphere of GJ 1214b from data collected with the Hubble Space Telescope. The Hubble observations used 96 hours of telescope time spread over 11 months. This was the largest Hubble program ever devoted to studying a single exoplanet.
The researchers describe their work as an important milestone on the road to identifying potentially habitable, Earth-like planets beyond our Solar System. The results appear in the Jan. 2 issue of the journal Nature.
"We really pushed the limits of what is possible with Hubble to make this measurement," said Kreidberg, a third-year graduate student and first author of the new paper. "This advance lays the foundation for characterizing other Earths with similar techniques."
"I think it's very exciting that we can use a telescope like Hubble that was never designed with this in mind, do these kinds of observations with such exquisite precision, and really nail down some property of a small planet orbiting a distant star," explained Bean, an assistant professor and the project's principal investigator.
GJ 1214b is located just 40 light-years from Earth, in the direction of the constellation Ophiuchus. Because of its proximity to our solar system and the small size of its host star, GJ 1214b is the most easily observed super-Earth. It transits, or passes in front of its parent star, every 38 hours, giving scientists an opportunity to study its atmosphere as starlight filters through it.
Kreidberg, Bean and their colleagues used Hubble to precisely measure the spectrum of GJ 1214b in near-infrared light, finding what they consider definitive evidence of high clouds blanketing the planet. These clouds hide any information about the composition and behavior of the lower atmosphere and surface.
The planet was discovered in 2009 by the MEarth Project, which monitors two thousand red dwarf stars for transiting planets. The planet was next targeted for follow-up observations to characterize its atmosphere. The first spectra, which were obtained by Bean in 2010 using a ground-based telescope, suggested that the planet's atmosphere either was predominantly water vapor or hydrogen-dominated with high-altitude clouds.
More precise Hubble observations made in 2012 and 2013 allowed the team to distinguish between these two scenarios. The news is about what they didn't find. The Hubble spectra revealed no chemical fingerprints whatsoever in the planet's atmosphere. This allowed the astronomers to rule out cloud-free atmospheres made of water vapor, methane, nitrogen, carbon monoxide, or carbon dioxide.
The best explanation for the new data is that there are high-altitude clouds in the atmosphere of the planet, though their composition is unknown. Models of super-Earth atmospheres predict clouds could be made out of potassium chloride or zinc sulfide at the scorching temperatures of 450 degrees Fahrenheit found on GJ 1214b. "You would expect very different kinds of clouds to form than you would expect, say, on Earth," Kreidberg said.
The launch of NASA's next major space telescope, the 6.5m James Webb Space Telescope (JWST), later this decade should reveal more about such worlds, Kreidberg said. "Looking forward, JWST will be transformative," she said. "The new capabilities of this telescope will allow us to peer through the clouds on planets like GJ 1214b. But more than that, it may open the door to studies of Earth-like planets around nearby stars."

新品UI系列包括40英寸和58英寸两个版本,40英寸售价为2999元,58英寸售价为5999元
新浪科技讯 12月31日上午消息,创维在沪正式发布子品牌"酷开"旗下首款4K超高清家电互联网电视U1系列,新品UI系列包括40英寸和58英寸两个版本,40英寸售价为2999元,58英寸售价为5999元,第一批工程机将于1月1日正式发售。此次创维酷开4K电视的发售,再次刷新了4K电视的价格底线,4K电视开始进入每英寸售百元区间。
创维于2013年9月发布子品牌"coocaa(酷开)",与阿里巴巴、爱奇艺等互联网公司合作,并主要通过天猫、京东等线上渠道进行销售,定位为家庭互联网电视品牌,成为创维直接与互联网公司所生产电视竞争的利器。
电视制造企业摘帽"单纯硬件供应商"
据介绍,通过首批酷开电视的发售,创维积累并吸引了众多使用者和关注者,首批发售至今三个月时间内创维通过论坛、微博、微信等沟通渠道关注、汇总用户需求,将用户意见和建议进行汇总、反馈、分析、改进后,反馈到新一代酷开互联网电视中。因此,酷开U1系列电视也就成为首款厂商与用户合作研发产物。其中,特别提到新一代"人体工学弧形遥控器"的开发就是完全接受了使用者的批评意见进行改进而生,并将为首批酷开电视用户免费更换。
创维集团副总裁、彩电事业本部总裁刘棠枝明确提出,反对外界将电视制造企业称之为"传统电视企业",认为电视制造企业不一定就是传统的,电视制造企业拥有精良的产品制造能力,在做好产品的基础上,重估并重视用户经营,并为此改变的制造企业不会输给互联网企业。同时他宣布2014年创维将由"单纯硬件供应商"向"硬件和内容供应商"转型。
做电视 仅有"互联网基因"不够 更要有"工业精神"
创维在两次"酷开"发布会上反复提到"工业精神",称这是互联网企业无法比拟的优势所在,而"酷开U1"家庭互联网电视正是"工业精神拥抱互联网"的产物。
两款酷开U1电视均采用4K超高清液晶面板,屏幕分辨率达到3840×2160,总像素点达到829万个,是1080P全高清电视总像素点的4倍。同等面积的屏幕,像素点越多,画面显示越清晰、细腻。结合搭载的4K图强引擎Pro,提升了智能电视的影像处理速度和应用优化水平。而在应用体验设计上采用"极简"理念,最新研发的人体工学遥控器仅设置了十三键,支持"盲操作",与天赐UI配合使用,让智能电视的操作更加简单。
在发布酷开U1系列4K电视的同时,创维宣布开通国内首个4K频道,真正为4K电视提供合格的超高清内容,不让4K电视成为摆设。
针对互联网企业提出的,"传统电视制造企业缺乏互联网基因,电视产业终将被颠覆"的话题,创维也做了回应。创维认为,电视产业是一个需要充分技术积累的领域,以创维为代表的电视制造企业与上游面板供应商、芯片提供商具有良好的合作历史,而电视整机生产、显示技术积累等更是优势所在,多年的制造历史为创维赋予了"工业精神",当制造企业开始重视用户经营,并为此改变的时候,这些企业不一定会输。而一些喊着"互联网精神",却生产不出精致产品,没有渠道、技术积淀的所谓互联网企业也不一定就能赢。(邢焱)

Testosterone in male songbirds may enhance desire to sing, but not song quality

Dec 30th 2013, 18:49
Dec. 30, 2013 — For the male canary, the ability to sing a pitch-perfect song is critical to wooing female canaries. As the seasons change, so does song quality and frequency. The hormone testosterone plays a role in this changing song behavior.
Researchers at The Johns Hopkins University have found that introducing testosterone in select areas of a male canary's brain can affect its ability to successfully attract and mate with a female through birdsong. They also found that enhancing song activity based on testosterone in one brain area can change the size of a separate brain area that regulates song quality. These findings could shed light on how testosterone acts in the human brain to regulate speech or help explain how anabolic steroids affect human behaviors.
In a paper recently published in the journal Proceedings of the National Academy of Sciences, graduate student and lead author Beau Alward along with senior author Gregory F. Ball, vice dean for science and research infrastructure and professor in the Department of Psychological and Brain Sciences in the Zanvyl Krieger School of Arts and Sciences, found that when male canaries received testosterone in a specific area in the brain, the frequency of the song increased. However, the quality of songs sung did not change in comparison to the male birds that received testosterone throughout the brain.
Hormones such as testosterone coordinate several areas of the avian brain to produce a physiological response, such as birdsong, said Alward. To determine how testosterone influences birdsong, Alward and Ball divided 20 canaries into two groups to receive a hormone implant.
One group received the testosterone injection in a specific area of the brain, the medial preoptic nucleus, or POM, which controls sexual motivation in many animals as well as in humans. The second group was received with testosterone that acted throughout the brain. A third group received no hormone treatment at all.
Alward said both groups of birds that received testosterone treatment sang but the researchers noticed in some cases the canaries' songs were sung poorly. The birds that only received testosterone to the POM sang at high rates, but could not produce high quality song that is most attractive to females.
"Our data suggests that testosterone needs to act in different areas of the brain to regulate the specific components of this complex social phenomenon," said Alward. "It appears that, like in so many other species, testosterone in the POM can regulate an animal's motivation, in this case, the motivation to sing. However, singing and courting a female is more than just motivation. There is the quality of the song that is required to successfully attract a mate and then the process of attending to the female, or singing to her, when she is there which requires the coordination of multiple brain regions."
Meanwhile, the canaries that received testosterone throughout the brain displayed high-quality typical canary vocalization behavior, consistent with the idea that the hormone acts on several different brain areas to regulate how much as well as how well the birds can sing.
The canary brain is considered a good model for brain study due to its ability to change its neural pathways and synapses in response to changes in behavior, the seasonal environment and injury. For the birds used in the study, the researchers artificially replicated a springtime environment to study the birdsong and mating habits that occur during the appropriate season. The birds responded to the spring-like conditions with birdsong and mating behaviors as they normally would at that time of the year.
The researchers say these results have broad implications for research concerning how steroid use in humans affects sexual behaviors and how hormones regulate the difference components of speech in humans.
"The hormones in these birds are identical to those in humans and they can regulate brain changes in a similar manner," said Ball.

Toward molecular explanation for schizophrenia
http://feeds.sciencedaily.com/~r/sciencedaily/~3/aEXjX6JC-LI/131230135050.htm
Dec 30th 2013, 18:50
Dec. 30, 2013 — Surprisingly little is known about schizophrenia. It was only recognized as a medical condition in the past few decades, and its exact causes remain unclear. Since there is no objective test for schizophrenia, its diagnosis is based on an assortment of reported symptoms. The standard treatment, antipsychotic medication, works less than half the time and becomes increasingly ineffective over time.
Now, Prof. Illana Gozes -- the Lily and Avraham Gildor Chair for the Investigation of Growth Factors, the director of the Adams Super Center for Brain Studies at the Sackler Faculty of Medicine, and a member of the Sagol School of Neuroscience at Tel Aviv University -- has discovered that an important cell-maintenance process called autophagy is reduced in the brains of schizophrenic patients. The findings, published in Nature's Molecular Psychiatry, advance the understanding of schizophrenia and could enable the development of new diagnostic tests and drug treatments for the disease.
"We discovered a new pathway that plays a part in schizophrenia," said Prof. Gozes. "By identifying and targeting the proteins known to be involved in the pathway, we may be able to diagnose and treat the disease in new and more effective ways."
Graduate students Avia Merenlender-Wagner, Anna Malishkevich, and Zeev Shemer of TAU, Prof. Brian Dean and colleagues of the University of Melbourne, and Prof. Galila Agam and Joseph Levine of Ben Gurion University of the Negev and Beer Sheva's Psychiatry Research Center and Mental Health Center collaborated on the research.
Mopping up
Autophagy is like the cell's housekeeping service, cleaning up unnecessary and dysfunctional cellular components. The process -- in which a membrane engulfs and consumes the clutter -- is essential to maintaining cellular health. But when autophagy is blocked, it can lead to cell death. Several studies have tentatively linked blocked autophagy to the death of brain cells seen in Alzheimer's disease.
Brain-cell death also occurs in schizophrenics, so Prof. Gozes and her colleagues set out to see if blocked autophagy could be involved in the progression of that condition as well. They found RNA evidence of decreased levels of the protein beclin 1 in the hippocampus of schizophrenia patients, a brain region central to learning and memory. Beclin 1 is central to initiating autophagy -- its deficit suggests that the process is indeed blocked in schizophrenia patients. Developing drugs to boost beclin 1 levels and restart autophagy could offer a new way to treat schizophrenia, the researchers say.
"It is all about balance," said Prof Gozes. "Paucity in beclin 1 may lead to decreased autophagy and enhanced cell death. Our research suggests that normalizing beclin 1 levels in schizophrenia patients could restore balance and prevent harmful brain-cell death."
Next, the researchers looked at protein levels in the blood of schizophrenia patients. They found no difference in beclin 1 levels, suggesting that the deficit is limited to the hippocampus. But the researchers also found increased levels of another protein, activity-dependent neuroprotective protein (ADNP), discovered by Prof. Gozes and shown to be essential for brain formation and function, in the patients' white blood cells. Previous studies have shown that ADNP is also deregulated in the brains of schizophrenia patients.
The researchers think the body may boost ADNP levels to protect the brain when beclin 1 levels fall and autophagy is derailed. ADNP, then, could potentially serve as a biomarker, allowing schizophrenia to be diagnosed with a simple blood test.
An illuminating discovery
To further explore the involvement of ADNP in autophagy, the researchers ran a biochemical test on the brains of mice. The test showed that ADNP interacts with LC3, another key protein regulating autophagy -- an interaction predicted by previous studies. In light of the newfound correlation between autophagy and schizophrenia, they believe that this interaction may constitute part of the mechanism by which ADNP protects the brain.
Prof. Gozes discovered ADNP in 1999 and carved a protein fragment, NAP, from it. NAP mimics the protein nerve cell protecting properties. In follow-up studies Prof. Gozes helped develop the drug candidate davunetide (NAP). In Phase II clinical trials, davunetide (NAP) improved the ability of schizophrenic patients to cope with daily life. A recent collaborative effort by Prof. Gozes and Dr. Sandra Cardoso and Dr. Raquel Esteves showed that NAP improved autophagy in cultures of brain-like cells. The current study further shows that NAP facilitates the interaction of ADNP and LC3, possibly accounting for NAP's results in schizophrenia patients. The researchers hope NAP will be just the first of their many discoveries to improve understanding and treatment of schizophrenia.

Toward molecular explanation for schizophrenia
http://feeds.sciencedaily.com/~r/sciencedaily/~3/aEXjX6JC-LI/131230135050.htm
Dec 30th 2013, 18:50
Dec. 30, 2013 — Surprisingly little is known about schizophrenia. It was only recognized as a medical condition in the past few decades, and its exact causes remain unclear. Since there is no objective test for schizophrenia, its diagnosis is based on an assortment of reported symptoms. The standard treatment, antipsychotic medication, works less than half the time and becomes increasingly ineffective over time.
Now, Prof. Illana Gozes -- the Lily and Avraham Gildor Chair for the Investigation of Growth Factors, the director of the Adams Super Center for Brain Studies at the Sackler Faculty of Medicine, and a member of the Sagol School of Neuroscience at Tel Aviv University -- has discovered that an important cell-maintenance process called autophagy is reduced in the brains of schizophrenic patients. The findings, published in Nature's Molecular Psychiatry, advance the understanding of schizophrenia and could enable the development of new diagnostic tests and drug treatments for the disease.
"We discovered a new pathway that plays a part in schizophrenia," said Prof. Gozes. "By identifying and targeting the proteins known to be involved in the pathway, we may be able to diagnose and treat the disease in new and more effective ways."
Graduate students Avia Merenlender-Wagner, Anna Malishkevich, and Zeev Shemer of TAU, Prof. Brian Dean and colleagues of the University of Melbourne, and Prof. Galila Agam and Joseph Levine of Ben Gurion University of the Negev and Beer Sheva's Psychiatry Research Center and Mental Health Center collaborated on the research.
Mopping up
Autophagy is like the cell's housekeeping service, cleaning up unnecessary and dysfunctional cellular components. The process -- in which a membrane engulfs and consumes the clutter -- is essential to maintaining cellular health. But when autophagy is blocked, it can lead to cell death. Several studies have tentatively linked blocked autophagy to the death of brain cells seen in Alzheimer's disease.
Brain-cell death also occurs in schizophrenics, so Prof. Gozes and her colleagues set out to see if blocked autophagy could be involved in the progression of that condition as well. They found RNA evidence of decreased levels of the protein beclin 1 in the hippocampus of schizophrenia patients, a brain region central to learning and memory. Beclin 1 is central to initiating autophagy -- its deficit suggests that the process is indeed blocked in schizophrenia patients. Developing drugs to boost beclin 1 levels and restart autophagy could offer a new way to treat schizophrenia, the researchers say.
"It is all about balance," said Prof Gozes. "Paucity in beclin 1 may lead to decreased autophagy and enhanced cell death. Our research suggests that normalizing beclin 1 levels in schizophrenia patients could restore balance and prevent harmful brain-cell death."
Next, the researchers looked at protein levels in the blood of schizophrenia patients. They found no difference in beclin 1 levels, suggesting that the deficit is limited to the hippocampus. But the researchers also found increased levels of another protein, activity-dependent neuroprotective protein (ADNP), discovered by Prof. Gozes and shown to be essential for brain formation and function, in the patients' white blood cells. Previous studies have shown that ADNP is also deregulated in the brains of schizophrenia patients.
The researchers think the body may boost ADNP levels to protect the brain when beclin 1 levels fall and autophagy is derailed. ADNP, then, could potentially serve as a biomarker, allowing schizophrenia to be diagnosed with a simple blood test.
An illuminating discovery
To further explore the involvement of ADNP in autophagy, the researchers ran a biochemical test on the brains of mice. The test showed that ADNP interacts with LC3, another key protein regulating autophagy -- an interaction predicted by previous studies. In light of the newfound correlation between autophagy and schizophrenia, they believe that this interaction may constitute part of the mechanism by which ADNP protects the brain.

Most clinical studies on vitamins flawed by poor methodology
http://feeds.sciencedaily.com/~r/sciencedaily/~3/Z-p03gwerDc/131230135106.htm
Dec 30th 2013, 18:51
Dec. 30, 2013 — Most large, clinical trials of vitamin supplements, including some that have concluded they are of no value or even harmful, have a flawed methodology that renders them largely useless in determining the real value of these micronutrients, a new analysis suggests.
Many projects have tried to study nutrients that are naturally available in the human diet the same way they would a powerful prescription drug. This leads to conclusions that have little scientific meaning, even less accuracy and often defy a wealth of other evidence, said Balz Frei, professor and director of the Linus Pauling Institute at Oregon State University, in a new review published in the journal Nutrients.
These flawed findings will persist until the approach to studying micronutrients is changed, Frei said. Such changes are needed to provide better, more scientifically valid information to consumers around the world who often have poor diets, do not meet intake recommendations for many vitamins and minerals, and might greatly benefit from something as simple as a daily multivitamin/mineral supplement.
Needed are new methodologies that accurately measure baseline nutrient levels, provide supplements or dietary changes only to subjects who clearly are inadequate or deficient, and then study the resulting changes in their health. Tests must be done with blood plasma or other measurements to verify that the intervention improved the subjects' micronutrient status along with biomarkers of health. And other approaches are also needed that better reflect the different ways in which nutrients behave in cell cultures, lab animals and the human body.
The new analysis specifically looked at problems with the historic study of vitamin C, but scientists say many of the observations are more broadly relevant to a wide range of vitamins, micro nutrients and studies.
"One of the obvious problems is that most large, clinical studies of vitamins have been done with groups such as doctors and nurses who are educated, informed, able to afford healthy food and routinely have better dietary standards than the public as a whole," said Frei, an international expert on vitamin C and antioxidants.
Vitamin or mineral supplements, or an improved diet, will primarily benefit people who are inadequate or deficient to begin with, OSU researchers said. But most modern clinical studies do not do baseline analysis to identify nutritional inadequacies and do not assess whether supplements have remedied those inadequacies. As a result, any clinical conclusion made with such methodology is pretty much useless, they said.
"More than 90 percent of U.S. adults don't get the required amounts of vitamins D and E for basic health," Frei said. "More than 40 percent don't get enough vitamin C, and half aren't getting enough vitamin A, calcium and magnesium. Smokers, the elderly, people who are obese, ill or injured often have elevated needs for vitamins and minerals.
"It's fine to tell people to eat better, but it's foolish to suggest that a multivitamin which costs a nickel a day is a bad idea."
Beyond that, many scientists studying these topics are unaware of ways in which nutrients may behave differently in something like a cell culture or lab animal, compared to the human body. This raises special challenges with vitamin C research in particular.
"In cell culture experiments that are commonly done in a high oxygen environment, vitamin C is unstable and can actually appear harmful," said Alexander Michels, an LPI research associate and lead author on this report. "And almost every animal in the world, unlike humans, is able to synthesize its own vitamin C and doesn't need to obtain it in the diet. That makes it difficult to do any lab animal tests with this vitamin that are relevant to humans."
Even though such studies often significantly understate the value of vitamin supplements, the largest and longest clinical trial of multivitamin/mineral supplements found a total reduction of cancer and cataract incidence in male physicians over the age of 50. It suggested that if every adult in the U.S. took such supplements it could prevent up to 130,000 cases of cancer each year, Frei said.
"The cancer reduction would be in addition to providing good basic health by supporting normal function of the body, metabolism and growth," he said. "If there's any drug out there that can do all this, it would be considered unethical to withhold it from the general public. But that's basically the same as recommending against multivitamin/mineral supplements."

新浪科技讯 12月31日晚间消息,4399方面宣布对如家工作室负责人陈金坤等人做出解聘的决定。不过,一位业内知情人士对新浪科技表示,陈金坤在此事件之前已经离开4399的创作团队。
昨日,有微博称"蔡文胜撤资4399,然后多玩接盘,4399最大的工作室——如家工作室的人删了代码跑路了……",但该微博随后被作者删除。此外,名为"页游八卦"的用户在微博上表示,"4399最大的工作室-----如家工作室大内乱。去年骆海坚还给工作室老大一人发一部宝马的使用权,今年年会还没开都大内乱了,可惜啊。。。。天下没有不散的宴席啊。"
对此,4399官方微博称,近日在传的4399广州公司小部分游戏研发人员离职并不会影响公司业务,蔡文胜一直是公司的重要股东,只是近来他因为个人原因慢慢淡出日常管理。
目前,陈金坤在4399的官网介绍为:原大型互联网公司运营总监,现任4399游戏平台项目制作人。精通产品运营和市场推广。目前研发上线产品有:神魔遮天、神魔仙界。
游戏行业观察人士郑化锋表示,4399对如家工作室可能是常规的边缘化裁员,由于页游市场并不像几年前那样火热,一个工作室的产品在定级方面会更加严格,而4399作为一家商业公司,面对创新力已经在市场上无法获得认可的产品,很自然的会边缘化甚至放弃。
根据《2013年中国游戏产业报告》,2013年中国游戏市场销售收入831.7亿元人民币,比2012年的602.8亿元增长38%。其中,端游536.6亿元,比2012年的451.2亿元增长18.9%;手游112.4亿元,比2012年的32.4亿元增长246.9%;页游127亿,比2012年增长57.4%;社交游戏市场实际销售收入54.1亿元;单机游戏市场实际销售收入0.89亿元,比2012年增长了18.0%。(伊凡)

沉浸在一本扣人心弦的小说中能触发大脑的可测量变化,这一效应在读完之后还能持续至少五天。论文(PDF)发表在《 Brain Connectivity》上。研究人员招募了21名学生,阅读Robert Harris的惊秫小说《Pompeii》。这本小说有很强的叙事线。在开始前五天,研究人员先用fMRI扫描大脑确定一个基线,然后让学生每天晚上在固定时间阅读小说的九分之一,早晨起来测量大脑。读完之后继续扫描五天。研究人员分析了大脑的几个区域,发现与感觉相关的特定区域的神经连通性在阅读后一直维持在基线以上水平。研究显示,参与创造性活动如阅读优秀小说能锻炼大脑。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

新浪科技讯北京时间12月31日下午消息,爱可视(Archos)周二公布了价位在50英镑(约合83美元)以下的智能手表及专门为家庭自动化设计的安卓平板电脑。
爱可视表示,新款智能手表类似Pebble产品,超薄超轻设计,可兼容苹果的ios和谷歌的安卓 OS系统。而Pebble智能手表价格为150美元。
爱可视目前尚未公布该智能手表的详细信息,但将会于1月7日至10日在拉斯维加斯的国际消费电子产品大展(CES)上展示该款产品。
据悉,智能手表将充当智能手机的连接器,显示短信、来电、新闻、天气/社交网帖甚至网站,它还可以充当用户的健康跟踪器。目前索尼、三星和美国高通(Qualcomm)是当今智能手表的主要生产者,许多其它公司也有望在CES上展示其产品。
爱可视还公布了为家庭自动化产品而生产的智能设备阵容,其中最引人注目的是一款7英寸的安卓智能家居平板电脑,它可启动或关闭智能电表、智能插座、摄影设备、气象监测器及其它相连的设备。例如,如果动态感应器捕捉到一个动作,平板电脑就会启动摄影设备或者打开电灯开关。
作为该款平板电脑的补充,爱可视宣布公司还研发了一款气象监测设备,可测量温度、湿度、二氧化碳水平及其它环境信息。该装置室内室外均可使用。另外,爱可视还将在CES上展示相关的摄影装备、智能开关和动态跟踪器。
爱可视还表示,该款平板可以连接安卓和iOS系统获取相关信息。
爱可视还声明可穿戴的健康跟踪器可用来设定健康指数。血压监护仪将检测心脏活动及血压,活跃度追踪器将充当步程器,而Connected Scale应用将测量体重和体内脂肪比例。一款名为"Connected Self App"的应用将收集健康跟踪器捕捉到的信息,并分析健康活跃度、设立健康目标。
爱可视新产品为首批基于蓝牙4.1技术,即被称为低功耗蓝牙(Bluetooth Low Energy)的产品。该项技术本月为制造商正式使用。(商鹊)

Valve的数字游戏发行平台Steam下线了许多游戏,但这些下线的游戏仍然留在买家的游戏库,玩家仍然可以下载和游戏。但在Square Enix关闭《Order of War: Challenge》的游戏服务器之后,Valve首次从玩家游戏库中移除了他们购买的这款游戏。Valve的做法可以理解,《Order of War: Challenge》使用了一个始终在线的DRM,服务器关闭了,游戏也就根本连不上了,尽管这款游戏有单机任务。这是数字世界的新趋势——买家并不真的拥有他们购买的游戏。福布斯的一篇文章提出了有关 数字所有权的问题:假如Steam关闭了,玩家购买的游戏怎么办?游戏库中的未下载游戏是否将永远失去?

Intel压赌平板机:99美元安卓

CES 2014大展将于一周后在拉斯维加斯上演,芯片巨头Intel将前往展示自己的笔记本、二合一、平板机等平台,尤其会把大量精力放在平板机上,并为合作伙伴提供全力支持,希望籍此在移动领域开疆拓土。
Intel已经发布了支持Windows 8/8.1系统的Bay Trail-T平台,很快将会推出安卓版本,并计划在2014年增加入门级版本,以期打造99美元安卓平板,争夺小尺寸、中低端市场。
Intel还贴心地为Windows 8.1 Bay Trail-T平板机划分了399、499、599美元三个价位档次,其中399美元的配备普通外壳、1.8GHz处理器、2GB DDR3内存、32GB存储。
安卓平板则分为:99-129美元7英寸、149-199美元7-8英寸、199-249美元8-10英寸、249美元以上10+英寸。处理器不但包括Bay Trail-T,还适用于未来的下一代14nm Cherry Trail。
二合一设备方面,Bay Trail-T、Cherry Trail平台也可以拿过来用,主攻288-499美元价位,搭配10/11寸屏幕。599美元或更高价位的,Intel大力推荐Bay Trail-M(奔腾/赛扬N)、Haswell-Y(超低压),而到了2014年下半年,将迎来14nm Broadwell-Y,屏幕尺寸也将扩大到11.6寸。
22nm Merrifield手机平台也将在2014年第一季度内正式登场,第三季度末再升级到22nm Moorefield。
PS:Intel这种划定价位、规格档次的做法由来已久,可以为厂商提供精确指导,但总感觉有些操心过度,一则将厂商卡得太死,二则市场是很广阔很灵活的,用户需求也差异很大,到现在还是这样做实在略显粗暴。或许,Intel的思维需要一些转变了。

消息称索尼将再次裁员 强化消费电子业务
http://tech.163.com/13/1231/15/9HEEHK8Q000915BD.html
Dec 31st 2013, 15:51
据《日经新闻》报道,索尼将再一次进行裁员。它计划下个月开始让旗下子公司Sony EMCS的部分员工提前退休,以强化受困于主流产品销售疲软的消费电子业务。
该子公司在日本共有5家工厂,员工总数为5000人。
索尼CEO平井一夫(Kazuo Hirai)正努力振兴公司处于亏损的电子业务。该公司的目标是,使得该业务在本财年扭亏为盈。
索尼第二财季录得净亏损193亿日元(约合1.83亿美元),之后它削减了对当前财年的盈利预期,同时还下调电视机、PC、数码相机等消费类产品的销量预期。
索尼在上一财年裁减了1万名员工。
据《日经新闻》称,由于来自日本电子产品巨头的竞争,索尼电子业务尤其遭受打击。消费者喜好的改变也对索尼的核心电子产品造成了影响。"随着智能手机和平板电脑的兴起,数码相机和PC的需求不断下降,新兴市场的经济增长也日渐衰弱。"
另外,早前有消息称,索尼和松下已经结束OLED大屏电视面板的合作生产。

LG早在2009年即已推出腕表手机,在可穿戴设备领域是一个先行者
新浪科技讯 北京时间12月27日早间消息,据《韩国先驱报》报道,知情人士透露,LG电子正在测试下一代旗舰智能手机G3,不仅将在其中配备指纹识别技术,还会推出两款与之配合使用的可穿戴设备。
知情人士说:"LG最近决定在即将发布的G3手机中采用指纹扫描器,目前正在对该产品进行一系列测试。"但与苹果iPhone 5s使用的技术不同,LG可能会采用滑动式指纹传感器。
除此之外,该公司还在开发多款可穿戴设备,包括G-Arch智能手表和G-Health健身腕带,这两款产品都有望与G3实现数据同步。
另外,G3还将采用Android 4.4奇巧系统,搭配4K显示屏和2.2Ghz八核处理器。
据悉,上述三款产品都将在明年2月的巴塞罗那移动世界大会(MWC)上展出。
业内人士预计,明年将有更多智能手机厂商在产品中安装指纹传感器。三星Galaxy S5就有可能采用生物识别技术,但目前还不清楚具体是虹膜识别还是指纹识别。而知情人士表示,苹果公司也将在更多产品中使用这一技术。(鼎宏)

2013年,"变革"成为了IT产业的主旋律。对于企业用户来说,也是如此。转型、收购、合作……云计算、大数据、移动化……各种概念、各种炒作,你方唱罢我登场。但对于所有企业和机构来说,有一个主旋律是永恒不变的,那就是"安全"!
在2013年即将逝去的时刻,我们有必要抓住它的尾巴,仔细审视,未雨绸缪,为打赢2014年的"安全战役"做好准备。
近日,畅享网记者采访了网络安全厂商WatchGuard中国区技术总监曾剑隽。曾剑隽根据2013年网络安全行业的发展态势,代表WatchGuard公司为我们预测了2014年全球范围内的八大安全趋势。
第一,网络绑架式攻击将越来越频繁。
近期网络上出现了一种攻击,叫CryptoLocker。有统计数据显示,目前每周约有12000台计算机会感染这个病毒。这种新型的蠕虫病毒会假冒企业邮箱的名义,给用户发送邮件,当用户点击这个邮件以后,电脑就会中毒。病毒会去查找用户的文档,如Excel文档或者PPT文档,然后把文档进行加密,使用户无法打开。加密之后,病毒的后台会给用户推送一封邮件,向用户索要大量的金额,用户支付之后,就可以解锁。如果不支付,文件则彻底消失。
而比特币的出现为这种网络绑架式攻击提供的更为方便和隐蔽的支付渠道。作为一种P2P形式的数字代码,比特币(BitCoin)不依靠特定货币机构发行,而是依据特定算法,通过大量计算产生。而P2P的去中心化特性和算法本身可以确保无法通过大量制造比特币来人为操控币值。
"这就相当于网络绑架的行为,只不过绑架的对象是文件和数据。"曾剑隽解释到,这种攻击造成较大影响有以下几种原因:其一是因为它仿冒企业邮件的方式,而用户对于企业或公共机构的邮件会放松警惕;其二是因为病毒采用的加密算法很难破解,病毒系统设计得很精巧,它能够根据用户的E—mail去寻找对应的联系人,生成相应的密钥。这样一来,黑客能够快速知道用户是否付了钱,把用户对应起来,一旦支付,密钥就打开了。其三,也就是最重要的一点,这种攻击的后台交易是用比特币来完成的,把资金流跟比特币绑在一起,后台有很完善的交易行为。美国当局也在进行调查,但是很难找到资金流、找到背后的利益链条。
"所以我们有理由相信,这种创新的攻击和绑架方式,是一个有一定投资行为的,有组织的攻击。"曾剑隽强调,"而这种模式在2014年也会被大量复制。"
第二,智能工业化控制网络安全威胁将频发。
在好莱坞电影中,常有犯罪分子进入银行或市政管理局,把所有的摄像头停止,或把所有的交通路况显示指向一个路口,甚至让化工厂的电力中断。2014年,这种情况会出现在现实生活中。而事实上,2013年已经出现了一个这样的实例,就是伊朗的核能源信息泄露事件。
"这是工业系统的攻击行为。"曾剑隽表示,"据了解,在国内包括发改委、工信部、科技部等在内的国家层面都在工业控制信息安全方面有专项投入,可能与这个事件不谋而合。"
虽然大部分工业控制系统与现在的互联网是物理隔离,但是随着物联网的到来,它可能会有某些层面的融合,如果犯罪分子靠近或者接入到工业控制系统当中,会造成不可估量的损失和社会后果。
近几年很多学者和研究人员也发现,工业控制、数据采集和监控系统还是存在很多漏洞的。据统计数据显示,在2013年已经有198起针对基础设施的攻击,包括医疗、交通、公共设施等领域,这些工业控制的设备里被发现有25个主要漏洞。而随着国际局势的变化,国家威胁很有可能会把这些漏洞真正暴露或者引发成事故。
第三,物联网将成为黑客重点攻击的目标。
目前人们使用的很多设备都是基于嵌入式系统的应用。例如智能手机就是一个嵌入式系统,手机上有很多各种各样的传感器,如速度传感器、位置传感器、加速度传感器、温度传感器和高度传感器等等。一部手机基本可以把一个人大部分的生活行为记录下来,如通过GPS能够记录位置信息,从位置信息中可以分析出个人的消费行为、业务行为等等;加速度传感器会反应个人的交通行为,是乘坐地铁、汽车、公交还是走路等等。
我们会发现,物联网已经把人通过各种各样的传感器,把每个个体进行了很细的量化。不只是手机,现在的汽车也有嵌入式系统,还有智能手表、医疗设备起搏器等等。我们正在进入一个被信息采集传感器包围的时代,而这些个人隐私信息很可能被别有用心的黑客获取和利用。
第四,高价值的目标将会更容易遭受信任链的攻击。
和木桶理论一样,安全程度是由最薄弱的环节决定的。像政府组织和世界五百强这些高价值的目标很容易成为攻击的对象,虽然这些组织或者公司自身的安全措施通常是非常先进且可靠的,但是也不可避免会有外包公司和雇佣制工人。这些工人或合作伙伴就处于信任链条上,就是安全链里最薄弱的环节,这些环节很容易遭受真正的攻击。
比如美国军方的信息就是个高价值但是难以进攻的目标。洛克席勒马丁公司是美国著名的军火商,过去曾有攻击者通过攻破这个公司的身份认证系统,通过它侵入美国军方,获取资料。
再如2013年全球闻名的斯诺登事件。斯诺登只是FBI一个外协公司的合同工,却获得了很多不应该访问和获取的信息,让当时的美国政府在全球外交当中处于很不利的局势。这个案例也充分证明了高价值的机构很容易遭受到信息链的攻击。
"所以希望用户不仅仅关注自身的安全,也要尽量审视所有的安全环节,评估出最弱的安全环节,并把它加强。"曾剑隽提示。
第五,恶意软件会来得更猛烈。
在过去的几年中,每年恶意软件的增长量都高达35%,这一趋势也将持续。在2014年,恶意软件有了新的攻击方式,它与有效的盈利模式结合,能够得到更快的执行和更快的拓展,越来越猛烈,所以用户要不断完善恶意软件攻击的系统。
据曾剑隽介绍,从黑客的角度来说,开发一个软件进行攻击的成本是最低的,而且效益最好。因为只要写一个软件,软件自身就会不断的复制,复制中又可以扩大攻击和影响的范围,能够获得很好的收益。而这也是促使很多机构或个人不断的开发和撰写恶意代码和软件最重要的原因。
第六,以社会工程学为基础的网络攻击会大量增加。
真正的技术方面的网络攻击可能会慢慢变少,但实际上它的攻击是通过社会工程学或者利用人性的弱点进行攻击的,这种行为会不断的增多。对人性弱点的捕获和利用,使攻击变得更加容易成功。
"众所周知,虽然每年都有新的攻击方式和特征出现,但是攻击防护的技术也在不断增强。如包括WatchGuard推出的UTM技术,在一个网关里能够过滤多种攻击行为,包括病毒、路型检测、反垃圾邮件、数据防泄露,还有高级可持续性威胁的防范。"曾剑隽谈到。而随着防护手段不断升级,黑客要通过技术手段攻击企业机构已经越来越难,但是任何一个机构或者网络最薄弱的环节往往是用户,因为用户的水平参差不齐,内部的行政人员或者外协厂家人员可能完全不懂计算机技术,只懂计算机操作。在这种技术手段无法突破的情况下,攻击者就会更关注人性心理的弱点。
第七,黑客会不断困扰美国的医疗保障系统。
美国的医疗保障系统是一个非常有争议的话题,同时也是以互联网为基础的,提供给一部分买不起或者说希望通过较多折扣购买医疗保险的病人的制度。这个系统相当复杂,据资料显示,大概有5亿行代码,相当于20倍的Facebook和10倍的XP系统,所以它出问题的概率会比较高。
曾剑隽指出,"在过去的一段时间里,已经出现了一些DDOS攻击,是针对HealthCare,所以我们认为,2014年很有可能会出现HealthCare数据破坏的案例,有人可能会通过这个系统增加自己的医疗保险覆盖面。"
第八,2014年将成为安全可视化的一年。
目前大部分企业还是依赖于防护的措施,如防火墙、防病毒措施。如果分离了这些措施系统,每个系统就会产生成千上万的数据,虽然现在有很多安全信息管理系统能够帮助企业分析这些数据,但这些数据还没有很好的呈现为可视化的观点。
曾剑隽表示,如果把大数据观念运用到安全数据分析里去,企业内部信息系统或者安全事件就能够比较清晰的通过数据分析展现出来,这会是2014年安全最热的方向。WatchGuard也将会在2014年推出一个Demention产品,可以帮助企业用户进行安全可视化管理。这个网关产品集成了多种安全控制措施,很容易在一个设备上采集多类的安全事件,WatchGuard可以对这些数据进行深度的挖掘和分析,通过报表的形式让安全趋势化、动态化和实时化的展现给用户。

新浪科技讯 12月31日上午消息,年末,多家互联网公司推出高收益率的理财产品,如网易理财的"添金计划"等。易观智库对此分析认为,互联网平台以补贴而来的高收益形式短期能带来大量用户,但从中长期获利角度考虑,不是长久之计。
临近年末,多家互联网公司纷纷加入理财产品战场,各家打出"高收益率"的旗号以期争夺更多用户,比如网易"添金计划"、百度"百发"等。
网易于本月25日推出了 "添金计划",5亿额度很快就被抢完。据悉,此计划是基于货币基金的活期理财。这款产品的特点在于,网易自掏腰包给参与活动的用户提供年化收益5%的现金红包补贴,期限3个月。网易高调补贴5%使得产品总收益有望超过10%。
易观智库认为,互联网金融时代,互联网平台在金融服务领域走的长久,不能仅是作为流量入口或获得支付、基金销售等牌照这般简单。线上货币型理财基金产品同质化特性,未来的趋势是市场充分竞争,总体收益回归正常水平。
互联网公司推出的理财产品或面临用户粘性的挑战。据悉,多家理财产品在上线两个月后,用户反响整体偏沉寂,有些产品在高收益竞争中出现了用户流失的现象。随着营销平台补贴力度的逐步减小,用户的稳定性与活跃度将成为检验平台能力的关键指标。
互联网金融平台只有从传统金融机构的渠道或单一业务主体转向综合交易服务商转变,完善自身的金融生态系统建立起丰富产品体系与持续服务模式,方能获得更好的用户粘性与更大、更稳定收入。
易观智库表示,目前在线理市场整体仍处于尝试阶段,跑马圈地的基础并不牢靠,未来还有很长路要走。(娜拉)

据中国科学院的一份研究报告,北京PM2.5的六个重要来源分别是土壤尘、燃煤、生物质燃烧、汽车尾气与垃圾焚烧、工业污染和二次无机气溶胶。其中,汽车尾气与垃圾焚烧占比最少,仅为4%,而最高比例来源则是工业污染和二次无机气溶胶,分别占25%和26%。总体上,化石燃料燃烧排放是北京PM2.5污染的主要来源。中科院研究认为,北京周边省份快速发展的工业生产活动,会带来跨境传输的污染。治理北京本地空气污染,不仅需要改善能源结构,还需要区域联合防治。此前有研究报告显示,河北省的煤炭消耗对京津冀地区的雾霾贡献最大。对于研究结论,有网民质疑,如果汽车尾气的危害最小,受雾霾困扰的城市实行车辆限行的原因何在。根据北京今年初实施的《重污染日应急方案》,在1月10日-15日的雾霾天气中,全市30%的公交车被要求停驶。This entry passed through the Full-Text RSS service — if this is your content and you're reading it on someone else's site, please read the FAQ at fivefilters.org/content-only/faq.php#publishers.

"人家挪威人拾金不昧,捡到后千里迢迢地寄回,结果到了国内还要收税,明明是旧机还要收10%的进口税,不交钱就不给拿!"
南都讯 记者单小亮 临近春节出境游渐热,你是否有在国外丢东西的经历,是否遇到过好心老外、"伤心"海关?近日广州有市民来电吐槽,其在欧洲旅游时弄丢一部iPad,谁知有好心老外捡到后按图索骥找到万里之外的失主,并自掏邮费寄回广州,谁知失主领取失物时,却被告知要缴10%行邮税。
老外掏邮费 海关寄税单
2013年11月份,广州市民卢先生远赴欧洲旅游,在其搭乘挪威一架飞机时,不慎遗忘了一部iPad,这是其女友刘小姐早前在国内购买的,里边有很多私人文件及照片,不过外观上有明显使用痕迹。卢先生及女友十分着急,本以为彻底找不回了,没想到回到国内之后,iPad竟失而复得。
事情说来颇为巧合,刘小姐在12月份收到一封邮件,对方声称在飞机上捡到一部iPad,询问其是否丢过、在哪丢过。原来,一位好心的挪威男子捡到了失物,通过iPad中的个人信息找到失主邮箱。在搞清楚情况之后,该好心老外竟默默掏了邮费,将iPad寄给万里之外的中国失主。
12月下旬,刘小姐收到广州石牌邮局一个通知,叫其到该邮局领取欧洲寄来的包裹,同时附有一张海关缴税单。这张税单名为广州海关"旅客行李、个人邮递物品进口税款缴纳证",列出了该物品的具体名称、完税价格、税率及进口税金额,其中税率为货价10%,进口关税200元。
海关:想免税拿凭证来
刘小姐颇为气恼,几次与石牌邮局沟通,但对方声称是代海关收钱,如有问题直接找海关。考虑到自己要急用机子,刘小姐上周只好交了200元关税拿回失物。
刘小姐及男友认为,自己领回失物天经地义,本身就是使用已久的旧iPad,不该被当成进口物品征税,何况机子里边还有个人资料,足以证明是自己的东西。广州海关热线人员回应称,对不在减免税范围之内的入境物品征收行邮税合法合规,尤其是对iPad这样的不予免税计算机品种。
至于当事人提出的质疑,广州海关热线人员解释称,除非是当事人提供相关证明,证明该物品是在国内购买的或者是出境时携带的,比如商品购买发票以及出境物品申报单,海关方面才会给予相应减免税。不过遗憾的是,刘小姐手中已无该物品发票,其男友在出境时亦未及时填写申报单。

惠普宣布裁员人数增加5000人
http://tech.163.com/13/1231/08/9HDM993A000915BD.html
Dec 31st 2013, 08:47
网易科技讯 12月31日消息,惠普周一在递交给SEC的10-K文件中称,公司将裁员34000人,这较此前公布的数据又增加了5000人。
2012年5月,惠普宣布裁员27000人,占员工总数的8%。而在同年9月,惠普又预计,公司裁员人数将达到29000人。
惠普在10-K文件中表示,由于市场压力持续,公司决定将裁人数员增加15%至34000人,而裁员期间的重组成本也预计增加15%至41亿美元。
惠普表示,本次大规模裁员将于2014年10月结束。公司CEO梅格·惠特曼(Meg Whitman)承诺,此后不会再进行新一轮大规模裁员。
惠普目前拥有33.18万名员工。截止2013年10月31日,惠普已经裁员24600人。
在过去几年中,惠普管理层不稳连续"换帅",公司在战略上不断摇摆,在移动设备市场中几乎无所作为。2011年9月,惠普目前的CEO惠特曼上任,做出了包括裁员在内的一系列削减成本举措,同时将公司未来的重点转向云计算、大数据及安全业务。(迟之)

LCD液晶显示技术在最近十年内成为了市场中的主流,完全代替了传统的CRT显像管技 术,并且在平板电视、桌面及商用大屏显示器、手机平板电脑、数码相机等诸多设备中都能够看到液晶屏幕的身影。而在这数十年的时间中,液晶显示技术自身也在 不断升级,不论是液晶面板还是IC芯片部分都有了很多改善,尤其是在如今智能手机与平板电脑盛行的今天,这类小尺寸液晶面板由于对制造工艺与成本的要求相 对更低,因此它们也是新型显示技术的实验场,如下一代显示技术OLED最初就是在手机中实现大规模量产,随后才开始出现在平板电视中。
过去的十几年中,液晶电视或显示器往往会搭载最新的显示技术,不过最前沿的液晶面板制造技术已迅速向度移动应用产品转移。上文中我们已经提到,除了这类产品 屏幕尺寸小,更容易实现量产和制造之外,它们的销量相对而言也更大,并且非常有利于推广,这也是各大液晶面板厂率先从移动终端"下手"的主要原因。
今 年超高清分辨率成为了最热门的技术,在苹果iPhone4手机的高分辨率"Retina"显示屏问世后,各大厂商开始不断提升屏幕的分辨率,而战火也一直 延续到了今年。不论是手机、平板电脑、显示器还是平板电视,它们的屏幕分辨率都在不断提升,其中在电视领域4K×2K超高清分辨率已经开始逐渐普及,而在 手机中搭载2K超高清屏幕的产品已经发布,不过这些小尺寸移动应用产品液晶显示面板的制造其实在很多方面都比大尺寸液晶显示面板制造更具挑战,如何保证更 高的良品率和可靠性是液晶面板厂需要面对的问题。
4K超高清分辨率是今年的主旋律,而在明年依旧是主角
此 外相对于平板电视这样的产品,便携式设备对产品的功耗要求更高,毕竟其直接会影响到续航时间,因此在2014年,显示技术需要改进的方向就是进一步稳定的 提供超高清分辨率液晶面板的供货及稳定性,已经尽可能的降低产品的功耗与成本,同时提高显示效果(如增加透光率、提升色彩饱和度等等),减小液晶面板的重 量与体积等等,而如果要实现这样的效果,就需要通过以下十种技术来进行完善,接下来我们就来看看2014年十大显示技术的发展趋势。
第2页:更精细的工艺提升分辨率
● 技术趋势一:更精细的面板制造工艺
在 上文中,我们已经提到了很多品牌的移动设备都将液晶显示屏幕的高分辨率作为卖点,并且从市场的反映来看,消费者确实能够察觉到分辨率提升所带来更好的效 果,并且也愿意为其买单,因此尝到甜头的厂商自然依旧会在这个方面继续下功夫。而对于液晶面板厂商而言有多种办法与手段配合来达到这个目的,进一步提升制 造面板工艺就是其中之一。
2007年液晶面板生产线的工艺为3.0μm,而在2014年之后,许多生产平板电脑与手机的面板将转移到8代线上完成,并且其工艺将推进到2.0μm,而在2016年或2017年,制造工艺将升级到1.5μm,这样就能为制造更高像素密度的显示屏幕做好准备。
液晶面板的制造工艺会越来越精细
● 技术趋势二:超低功耗驱动技术
降 低功耗始终是各个厂商需要面对的问题,尤其是针对移动设备而言,在电池技术发展缓慢的情况下,作为耗电量最高的部件,液晶屏幕的功耗在很大程度上决定了移 动设备的待机时间。除了从液晶面板开口率、TFT材质等方面之外,2014年液晶面板厂则也将会从驱动电路方面入手来进一步降低液晶屏幕的耗电量。
从2006年一直到今年为止,液晶面板的驱动IC一直采用的是纵向翻转的方式(column inversion),而从2014年开始则改变为"暂停驱动(pause driving)",这样就能够降低驱动液晶面板所需要的功耗,达到省电的目的。
LTPS低温多晶硅技术依旧在不断改良
● 技术趋势三:LTPS低温多晶硅技术
LTPS 低温多晶硅技术技术虽然只到今年我们才经常听到这个名词,但实际上很早液晶面板厂商就有研究,从2006年开始到现在,液晶面板厂一直在改善其分子的弹性 稳定性(ELA stability),而从2014年开始,LTPS低温多晶硅技术也会有一定的改善,其采用了选择性结晶分子,其目的是提高像素开口 率,增加传输速度和亮度,同时或可以通过减少背光照明达到降低能量消耗的目的。
第3页:超窄边框减小体积
● 技术趋势之四:超窄边框技术
近 几年不论是平板电视还是液晶显示器,很多厂商都在推广一种叫做"无边框"的理念,当然其并不是让显示设备真的没有边框,而是在它们不工作时让屏幕表面与边 框融合在一起,造成一种没有边框的错觉。尽管其还是有边框的存在,但相对于传统产品其边框厚度已经有了大幅度的缩减,而在2014年,进一步缩小边框也是 他们研究的人物之一。
有业内相关人士曾经为我们透露,从2014年开始部分液晶面板厂将会采用一种叫做 "critical technology(临界边框技术)"的解决方案,将液晶面板的边框变得更加细窄,在大屏幕电视、手机和平板电脑中都会采用这样的 技术。超窄边框不但能够让相关设备体积变得更加小巧,而且在视觉上也更加有冲击力、更加美观。
超窄边框概念已经应用在很多电视、显示器和手机中
● 技术趋势之五:更高的刷新率(液晶面板驱动电路的更新)
由 于液晶显示技术天生的"顽疾",液晶分子在发生偏转时需要一定的时间,我们将这段时间称为"响应时间",因此在表现动态画面时都会出现模糊、不清晰的情 况。尤其是在平板电视领域,消费者关注的就是动态画面的清晰度,因此在液晶分子响应速度无法继续提升的情况下,各大厂商就只能通过刷新率来入手,而通过对 液晶面板驱动电路部分的更新则是最为有效的。
液晶电视厂商通过特有的技术(如插帧等)方式来提高刷新率,但其是针对液晶面板天生的 "缺陷"所做的弥补,其多多少少还是会有些不自然,而如果是从液晶面板自身的驱动电路技术进行改善,效果则会更加明显。目前的液晶电视采用的是 "TBA/HTVA"的驱动方式,而从2014年开始,液晶电视将会改变为"Nega FFS"的方式,并且在未来(可能是2016年)采用"USH"的 驱动方式,让动态画面变得更加流畅。
下一代iPhone可能会采用更先进的触控液晶面板
● 技术趋势之六:光学触摸校准方式
苹 果iPhone的出现让大家开始习惯用触摸的方式来操作手机,因此上游厂商从来没有放弃对触摸相关技术、硬件的改善,如LG Display在近年推出的 in cell触控一体式的液晶面板等等。而据液晶面板厂商透露,明年下一代苹果iPhone手机将采用新的光线触摸校准方式,其将进一步提升触摸的精准 性和流畅性,在增加触摸信号传输速率的同时还可以增强屏幕的性能。当然即使iPhone下一代产品没有采用这项技术,相信它的竞争对手们也不会错过的。
● 技术趋势之七:Oxide TFT金属氧化物薄膜晶体管
Oxide TFT 金属氧化物薄膜晶体管在2011年发布上市,如夏普的IGZO液晶面板以及LG Display推出的AMOLED都采用了这项技术,不过受限于产能和技 术的成熟程度,它并没有大规模的量产,而从明年开始除了LG Display和夏普之外,其他液晶面板厂商也将会加入到这个战局中,有助于降低其成本并大 规模生产。Oxide TFT同样可以帮助减少边框宽度,它们的高电子迁移率可以减少GOA(栅阵列)的电路尺寸,同时也可以降低液晶面板的功耗,并有助 于制造高分辨率的产品。
第4页:全面提升显示效果
● 技术趋势之八:Quantum Dot BLU量子点技术
对 于一块显示屏幕,除了能够通过提升其分辨率增加细腻度来获得更好的体验之外,提升屏幕的色彩饱和度也可以更讨好人们的眼球。基于 Quantum Dot BLU量子点技术为的背光源可以同时提高发光效率和色彩饱和度。相较于传统的提高色彩饱和度的方式,如使用会影响传输速度的色彩 抗蚀剂,这种方式更为先进,可以使用较小成本就能让小尺寸屏幕的NTSC色域值达到100%以上(通常为72%左右甚至更低)。众所周知OLED在画面色 彩上有很大的优势,如三星推出的AMOLED屏幕可以轻松让NTSC色域值超过100%,而以量子点为基础的背光源可以向LCD面板提供相当于 AMOLED的色彩表现。
● 技术趋势之九:染料型彩膜(dye type CF)技术
与 低温多晶硅技术(LTPS)、金属氧化物薄膜晶体管(oxide TFT)相同的是,染料型彩膜可以提高像素开口率,增加传输速度和亮度,只是其是将目前 现有的透光膜进行改良,实现更好的透光率,减少光线在透光膜中能量的损失。目前三星Display和友达光电采用的是混合染料型彩膜技术,而未来液晶面板 厂则可能会引入pure dye RGB技术,让其性能进一步提升,并且增加红、绿、蓝三原色的纯度。
在传统的RGB像素中加入黄色,这是夏普RGBY的基本原理
● 技术趋势之十:RGBW或RGBY四色技术
夏 普、LG Display与Japan Display(JDI)先后在今年内都推出了四色技术,它们的原理非常接近:之前人们用红、绿、蓝三个像素点来 显示一个像素,而如今则在三原色中加入另外一个像素,即使用四个子像素来显示一个像素,其中夏普加入的是黄色(Y),目的是增加液晶面板的色彩饱和度和色 彩数量,而LG Display则是加入了白色(W),其可以在不消耗更多电量的情况下增加屏幕的亮度。
四色技术让液晶面板能够显示更多的色彩数量
相 对而言,由于夏普的RGBY四色技术难度更大,在保证色彩不失真的情况下维持这四个基本像素的分配平衡是一件难度很大的事情,并且在制造工艺上也相对较为 复杂,因此四色面板产能也相对较低,而RGBW则不会破坏之前RGB的平衡,因此在液晶面板的良品率上要好很多。据业内人士透露,未来厂商会引入 Pentile RGBW技术,进一步对先有的面板进行优化,增加透光率并让白光平衡更准确。
未来平板电视和智能手机将会率先采用更新的显示技术
● 总结
从上文中,我们可以看到虽然2014年液晶面板厂希望引入的显示相关技术种类非常多,但是目的却非常明确:用成本更低、更成熟的方法来提高液晶面板的分辨 率、色彩效果,并减小它的体积和功耗,而这些技术分别从驱动IC电路、液晶面板本身、背光模组、透光膜等部件着手进行改善和优化。尽管"高性能"与"低成 本"是鱼和熊掌不可兼得的事情,但是液晶面板厂商则希望尽可能同时做到这两点,因此才开发了一系列的新技术。相对而言这些上游的显示技术显得比较"低 调",也许在不建议之间,在明年的一些热卖产品中就有它们的身影。

绝非雾里看花 2014年十大显示技术趋势
http://go.rss.sina.com.cn/redirect.php?url=http://tech.sina.com.cn/n/2013-12-31/09129057084.shtml
Dec 31st 2013, 01:12
LCD液晶显示技术在最近十年内成为了市场中的主流,完全代替了传统的CRT显像管技 术,并且在平板电视、桌面及商用大屏显示器、手机平板电脑、数码相机等诸多设备中都能够看到液晶屏幕的身影。而在这数十年的时间中,液晶显示技术自身也在 不断升级,不论是液晶面板还是IC芯片部分都有了很多改善,尤其是在如今智能手机与平板电脑盛行的今天,这类小尺寸液晶面板由于对制造工艺与成本的要求相 对更低,因此它们也是新型显示技术的实验场,如下一代显示技术OLED最初就是在手机中实现大规模量产,随后才开始出现在平板电视中。
过去的十几年中,液晶电视或显示器往往会搭载最新的显示技术,不过最前沿的液晶面板制造技术已迅速向度移动应用产品转移。上文中我们已经提到,除了这类产品 屏幕尺寸小,更容易实现量产和制造之外,它们的销量相对而言也更大,并且非常有利于推广,这也是各大液晶面板厂率先从移动终端"下手"的主要原因。
今 年超高清分辨率成为了最热门的技术,在苹果iPhone4手机的高分辨率"Retina"显示屏问世后,各大厂商开始不断提升屏幕的分辨率,而战火也一直 延续到了今年。不论是手机、平板电脑、显示器还是平板电视,它们的屏幕分辨率都在不断提升,其中在电视领域4K×2K超高清分辨率已经开始逐渐普及,而在 手机中搭载2K超高清屏幕的产品已经发布,不过这些小尺寸移动应用产品液晶显示面板的制造其实在很多方面都比大尺寸液晶显示面板制造更具挑战,如何保证更 高的良品率和可靠性是液晶面板厂需要面对的问题。
4K超高清分辨率是今年的主旋律,而在明年依旧是主角
此 外相对于平板电视这样的产品,便携式设备对产品的功耗要求更高,毕竟其直接会影响到续航时间,因此在2014年,显示技术需要改进的方向就是进一步稳定的 提供超高清分辨率液晶面板的供货及稳定性,已经尽可能的降低产品的功耗与成本,同时提高显示效果(如增加透光率、提升色彩饱和度等等),减小液晶面板的重 量与体积等等,而如果要实现这样的效果,就需要通过以下十种技术来进行完善,接下来我们就来看看2014年十大显示技术的发展趋势。
第2页:更精细的工艺提升分辨率
● 技术趋势一:更精细的面板制造工艺
在 上文中,我们已经提到了很多品牌的移动设备都将液晶显示屏幕的高分辨率作为卖点,并且从市场的反映来看,消费者确实能够察觉到分辨率提升所带来更好的效 果,并且也愿意为其买单,因此尝到甜头的厂商自然依旧会在这个方面继续下功夫。而对于液晶面板厂商而言有多种办法与手段配合来达到这个目的,进一步提升制 造面板工艺就是其中之一。
2007年液晶面板生产线的工艺为3.0μm,而在2014年之后,许多生产平板电脑与手机的面板将转移到8代线上完成,并且其工艺将推进到2.0μm,而在2016年或2017年,制造工艺将升级到1.5μm,这样就能为制造更高像素密度的显示屏幕做好准备。
液晶面板的制造工艺会越来越精细
● 技术趋势二:超低功耗驱动技术
降 低功耗始终是各个厂商需要面对的问题,尤其是针对移动设备而言,在电池技术发展缓慢的情况下,作为耗电量最高的部件,液晶屏幕的功耗在很大程度上决定了移 动设备的待机时间。除了从液晶面板开口率、TFT材质等方面之外,2014年液晶面板厂则也将会从驱动电路方面入手来进一步降低液晶屏幕的耗电量。
从2006年一直到今年为止,液晶面板的驱动IC一直采用的是纵向翻转的方式(column inversion),而从2014年开始则改变为"暂停驱动(pause driving)",这样就能够降低驱动液晶面板所需要的功耗,达到省电的目的。
LTPS低温多晶硅技术依旧在不断改良
● 技术趋势三:LTPS低温多晶硅技术
LTPS 低温多晶硅技术技术虽然只到今年我们才经常听到这个名词,但实际上很早液晶面板厂商就有研究,从2006年开始到现在,液晶面板厂一直在改善其分子的弹性 稳定性(ELA stability),而从2014年开始,LTPS低温多晶硅技术也会有一定的改善,其采用了选择性结晶分子,其目的是提高像素开口 率,增加传输速度和亮度,同时或可以通过减少背光照明达到降低能量消耗的目的。
第3页:超窄边框减小体积
● 技术趋势之四:超窄边框技术
近 几年不论是平板电视还是液晶显示器,很多厂商都在推广一种叫做"无边框"的理念,当然其并不是让显示设备真的没有边框,而是在它们不工作时让屏幕表面与边 框融合在一起,造成一种没有边框的错觉。尽管其还是有边框的存在,但相对于传统产品其边框厚度已经有了大幅度的缩减,而在2014年,进一步缩小边框也是 他们研究的人物之一。
有业内相关人士曾经为我们透露,从2014年开始部分液晶面板厂将会采用一种叫做 "critical technology(临界边框技术)"的解决方案,将液晶面板的边框变得更加细窄,在大屏幕电视、手机和平板电脑中都会采用这样的 技术。超窄边框不但能够让相关设备体积变得更加小巧,而且在视觉上也更加有冲击力、更加美观。
超窄边框概念已经应用在很多电视、显示器和手机中
● 技术趋势之五:更高的刷新率(液晶面板驱动电路的更新)
由 于液晶显示技术天生的"顽疾",液晶分子在发生偏转时需要一定的时间,我们将这段时间称为"响应时间",因此在表现动态画面时都会出现模糊、不清晰的情 况。尤其是在平板电视领域,消费者关注的就是动态画面的清晰度,因此在液晶分子响应速度无法继续提升的情况下,各大厂商就只能通过刷新率来入手,而通过对 液晶面板驱动电路部分的更新则是最为有效的。
液晶电视厂商通过特有的技术(如插帧等)方式来提高刷新率,但其是针对液晶面板天生的 "缺陷"所做的弥补,其多多少少还是会有些不自然,而如果是从液晶面板自身的驱动电路技术进行改善,效果则会更加明显。目前的液晶电视采用的是 "TBA/HTVA"的驱动方式,而从2014年开始,液晶电视将会改变为"Nega FFS"的方式,并且在未来(可能是2016年)采用"USH"的 驱动方式,让动态画面变得更加流畅。
下一代iPhone可能会采用更先进的触控液晶面板
● 技术趋势之六:光学触摸校准方式
苹 果iPhone的出现让大家开始习惯用触摸的方式来操作手机,因此上游厂商从来没有放弃对触摸相关技术、硬件的改善,如LG Display在近年推出的 in cell触控一体式的液晶面板等等。而据液晶面板厂商透露,明年下一代苹果iPhone手机将采用新的光线触摸校准方式,其将进一步提升触摸的精准 性和流畅性,在增加触摸信号传输速率的同时还可以增强屏幕的性能。当然即使iPhone下一代产品没有采用这项技术,相信它的竞争对手们也不会错过的。
● 技术趋势之七:Oxide TFT金属氧化物薄膜晶体管
Oxide TFT 金属氧化物薄膜晶体管在2011年发布上市,如夏普的IGZO液晶面板以及LG Display推出的AMOLED都采用了这项技术,不过受限于产能和技 术的成熟程度,它并没有大规模的量产,而从明年开始除了LG Display和夏普之外,其他液晶面板厂商也将会加入到这个战局中,有助于降低其成本并大 规模生产。Oxide TFT同样可以帮助减少边框宽度,它们的高电子迁移率可以减少GOA(栅阵列)的电路尺寸,同时也可以降低液晶面板的功耗,并有助 于制造高分辨率的产品。
第4页:全面提升显示效果
● 技术趋势之八:Quantum Dot BLU量子点技术
对 于一块显示屏幕,除了能够通过提升其分辨率增加细腻度来获得更好的体验之外,提升屏幕的色彩饱和度也可以更讨好人们的眼球。基于 Quantum Dot BLU量子点技术为的背光源可以同时提高发光效率和色彩饱和度。相较于传统的提高色彩饱和度的方式,如使用会影响传输速度的色彩 抗蚀剂,这种方式更为先进,可以使用较小成本就能让小尺寸屏幕的NTSC色域值达到100%以上(通常为72%左右甚至更低)。众所周知OLED在画面色 彩上有很大的优势,如三星推出的AMOLED屏幕可以轻松让NTSC色域值超过100%,而以量子点为基础的背光源可以向LCD面板提供相当于 AMOLED的色彩表现。
● 技术趋势之九:染料型彩膜(dye type CF)技术
与 低温多晶硅技术(LTPS)、金属氧化物薄膜晶体管(oxide TFT)相同的是,染料型彩膜可以提高像素开口率,增加传输速度和亮度,只是其是将目前 现有的透光膜进行改良,实现更好的透光率,减少光线在透光膜中能量的损失。目前三星Display和友达光电采用的是混合染料型彩膜技术,而未来液晶面板 厂则可能会引入pure dye RGB技术,让其性能进一步提升,并且增加红、绿、蓝三原色的纯度。
在传统的RGB像素中加入黄色,这是夏普RGBY的基本原理
● 技术趋势之十:RGBW或RGBY四色技术
夏 普、LG Display与Japan Display(JDI)先后在今年内都推出了四色技术,它们的原理非常接近:之前人们用红、绿、蓝三个像素点来 显示一个像素,而如今则在三原色中加入另外一个像素,即使用四个子像素来显示一个像素,其中夏普加入的是黄色(Y),目的是增加液晶面板的色彩饱和度和色 彩数量,而LG Display则是加入了白色(W),其可以在不消耗更多电量的情况下增加屏幕的亮度。

让我们一起期待吧 微软2014年大动作猜想
http://go.rss.sina.com.cn/redirect.php?url=http://tech.sina.com.cn/n/pad/2013-12-31/09169057093.shtml
Dec 31st 2013, 01:16
微软公司对于普通消费者来说,最熟悉的就是Windows系统,这样很容易让人们对微软有软件公司的认知,除了操作系统外,微软还有不少值得我们购买的产品。对于2014年来说,微软有哪些软硬件产品让用户期待呢?
当然,这都是过去的事情,在2014年,微软除了加强传统的产品如Windows的体验之外,还将大力大展移动互联网和硬件产品,下面一起来看看微软在明年会有什么大动作。
Windows 8.2及Windows 9
显然,由于受到竞争对手的冲击,即使在最传统的系统平台领域,微软也在逐渐改变。自Windows 8开始,一年一次的大幅更新成为新标准,在2013年我们看到了Windows 8.1,预计明年Windows 8.2也会到来,将提供更好的触摸体验以及更多设备的支持。显然,微软的这个决定是非常必要的,因为Windows 8不仅仅是面向传统PC的平台,其双界面带来的移动互联网特性,也使得市场中出现了大量的混合设计和Windows平板,是微软与苹果、谷歌在移动平台竞 争的核心关键。
同时,传闻中的Windows 9也会在2014年逐渐浮出水面,有望带来更为统一的触控操作体验和更加丰富的应用程序。不过,似乎微软并不会针对目前Windows 8的Metro UI和传统桌面的设计进行大幅修改,这似乎有些令人失望,毕竟分裂式的应用和操作感受令很多用户不满。但是,Windows RT的失败让微软无法专门开发一个用户移动产品的平台,而抛弃桌面老用户显然也是不明智的,所以我们希望微软能够在Windows 9中找到一个最佳的平衡点,让移动应用和传统PC应用更有机地结合起来。
Windows Phone 8
传闻中的Windows Phone 8.1更新并没有在今年放出,所以基本肯定这个位居第三的智能手机平台会在2014年迎来一次大修。根据相关泄露信息显示,Windows Phone 8.1的界面效果相比目前最新的GDR3并没有太大改变,但是能够更好地支持1080P分辨率,界面布局上也更为灵活。
同时,一个名为"cortana "的语音助理功能也将登陆Windows Phone 8.1平台,微软或将采用基于Xbox Kinect的语音控制技术,来与苹果siri和Google Now竞争,将为WP手机添加语音短信、语音任务等新功能。另外,相传Windows Phone 8.1还将新增通知中心功能,并提升桌面瓷砖的实时更新能力,还将改善多任务系统,以实现更好的性能及续航能力。
Xbox One
Xbox系列游戏主机可以说是微软为数不多的成功硬件产品,最新的Xbox One依然大卖,同时在2014年会有更多的游戏大作和专属配件登场。
与大多数刚刚上市的游戏主机一样,目前Xbox One的游戏资源还比较匮乏,但预计2014年上市的《光环5》等超大作,会极大地提升主机销量和口碑。另外,微软也会推出更多的Xbox One应用程序和更新,改善系统界面以及Kinect的使用体验。
Surface系列平板电脑
显然,被微软寄予厚望的Surface系列平板电脑没有获得预期般的成功,即使是在年末发售的续作Surface 2及Pro,影响力依然有限。不过微软是一家资金实力雄厚的科技公司,转型硬件领域也一直是其目标,所以预计在2014年下半年,Surface 3也会闪亮登场。硬件方面,搭载英特尔最新处理器显然是意料之中的事情,将实现更好的性能表现及续航能力。同时,机身设计可能会更为轻薄,在 Surface 2上没有得到改进的部分,也将得到改善。
微软需要面对的一个难题可能是产品类型的划分上,Surface(RT)和Surface Pro虽然外形相似,但是使用体验完全不同,似乎用户对阉割了传统桌面及EXE程序兼容能力的RT版机型仍然没有太大兴趣。那么,是继续推广RT设备,采 用更轻薄的设计并降低价格;还是专注于Pro设备,用"完整windows"的卖点来与iPad和Android平板竞争,是Surface系列需要面对 的一个问题。
iOS和Android平台的Office应用
很多用户一直都希望微软能够推出iOS和Android平台的官方Office应用,但微软在2013年仅推出了一个精简的Office 365版本,而真正的完整官方本地版本,则有可能在2014年中期推出。
虽然微软是一家系统、软件主导的公司,但它也在努力向硬件厂商转型。一直没有推出其他平台Office应用的一个重要原因,便是Surface 平板,其最大竞争对手无疑是苹果iPad和众多Android平板;而在Surface完全不占优势的情况下,内置Office应用几乎成了唯一的卖点。 所以,微软会不会推出其他平台的Office应用,仍然是一个未知数。
内部变化和新的CEO
说实话,史蒂夫·鲍尔默并不是一个受欢迎的CEO,所以他的辞职可以说是微软在2013年带给人们的最大惊喜了。相比比尔·盖茨,史蒂夫·鲍尔 默时代的微软显然缺乏创新和前瞻性,导致微软在移动互联网和硬件产品上一直没有什么起色,显然落后于苹果和谷歌。据悉,新的CEO人选将在史蒂芬·埃洛普 (前诺基亚CEO)、艾伦·穆拉利(前福特CEO)以及托尼·贝茨(Skype CEO)中产生,不论是谁,都可谓是任重而道远。
另外,在2013年,微软公司内部也废除了史蒂夫·鲍尔默时期的员工分级制度。这种制度鼓励员工之间进行激烈竞争而非协同合作,所以导致了大量 办公室斗争和人才流失,自然也会影响产品。这个改变有望让2014年的微软创建出更为强大、更具创造力的团队,对产品的影响自然也是积极的。
总结
作为一个传统的桌面系统巨鳄,微软凭借Windows获得了很多辉煌,但在移动互联时代,显然它还需要更丰富的组成结构,才能与时俱进,获得更 多的利润增长点。显然,转型期是痛苦的,竞争对手也极为强劲,不论是苹果、谷歌还是索尼,几乎都有针锋相对的产品来打击微软的产品,比如 iPhone/iPad、Android或是PS4。对于微软来说,即将换帅的2014年将面临更多挑战,当然机会也是巨大的;而对于消费者来说,我们希 望看到微软的反击,因为这将带来更激烈的竞争,也会带来更多的创新产品,最大的受益者自然会是消费者。

惠普被控贿赂俄罗斯政府机关
http://tech.163.com/13/1231/06/9HDD6RFK000915BD.html

网易科技讯 12月31日消息,据外国媒体报道,惠普因贿赂指控正接受美国两大监管部门的调查,目前正展开"深入协商"。
惠普正接受美国司法部(Department of Justice)和美国证券交易委员会(SEC)的调查。惠普面临的指控是该公司的一些前任和现任雇员曾以行贿手段赢得俄罗斯政府机关的信息技术合约。行贿指控涉及惠普位于德国的前子公司和俄罗斯总检察院(Russian General Prosecutors Office)之间一笔金额达3500万欧元的交易,涉案时间自2001年至2006年。交易的内容是惠普子公司在俄罗斯代理安装全新的IT网络。惠普呈递给美国证交会的年度10-K文件披露了这一事件。
德国当局已起诉四个涉案人员,其中包括两名惠普前雇员和一名现任员工,指控罪名是行贿、违反信托和逃税。美国司法部(DOJ)已根据《反海外腐败法》(Foreign Corrupt Practices Act)对这次交易展开调查。在10-K文件中,惠普表示美国、墨西哥和波兰的监管机构正在调查惠普与这些国家某些公共部门达成的协议中可能涉及的贿赂行为。
惠普在文件中表示,它正与调查俄罗斯贿赂案件的所有部门展开合作,并与美国当局协商解决此事。这些调查始于2010年。
近几年,美国高科技公司频频爆出贿赂新闻。去年,甲骨文支付200万美元就印度子公司涉嫌违反美国海外贿赂法达成和解。IBM在中韩两国行贿被罚1000万美元。今年前微软中国代表指控微软给回扣争取合同,美国当局对此展开了调查。(陈思)
