在去年，给笔者印象最深刻的机型应该就是iPhone 5s了。面对N多型号和版本，在挑选对应的网络的时候还是有着不晓得问题的。而近日有消息显示，三星Galaxy S5共将推出18个版本，其中，有些版本的参数还不尽相同，看来挑选的时候又有不少问题了。
这次Galaxy S5的型号曝光由外媒送出，型号的细分多达18款。除了美国三大运营商外，中国、日本、韩国均有相应版本，此外还有亚洲、欧洲版本。最为重要的是，此次发 布的Galaxy S5会有两个版本，一个是机身材质塑料，而另外一个是金属(金属后壳/该版本的S5可能最后会被冠以其它的名称)，两者的预计售价分别是650欧元(折合 人民币5350元左右)和800欧元(折合人民币6600元)。
硬件方面，Galaxy S5采用高通骁龙805/Exynos 6处理器、5.25寸2560×1440的屏幕(Super AMOLED)、Android 4.4系统、1600万像素摄像头(支持光学防抖)等等。值得一提的是，Galaxy S5将配备一块2900mAh的电池(比Galaxy S4大了300mAh)，而且支持快速充电，2小时可完全充满。此外，该机还有望配备指纹识别。
▲目前感觉这个版本会是最为靠谱的 不知道各位是不是喜欢
据称三星Galaxy S5将于2月23日提前发布，同时将在4月份正式发售。而在过去的一年，三星全球智能手机出货量首次突破10亿大关，达到10.04亿部，相比2012年 的7.253亿部大涨38.4%。不过旗舰机型Galaxy S4的销量并未达到预期，不知在今年的产品中三星能否再做突破。

此前三星已经正式发出邀请函，将在下月底的MWC发布Tizen系统和搭载该系统的新机型。近日韩国网站Moveplayer正式曝光了首款三星Tizen手机正面图，该机型号为ZEQ9000，将搭载高通骁龙800处理器，未来还将推出多个版本。
三星Tizen手机ZEQ9000(图片来自韩国网站)
从渲染图上看，外观毫无疑问就是延续三星手机的血统，比较像三星GALAXY S3和三星WP手机ATIV S的样子。根据韩国网站说法该机隶属全新"ZEQ"系列，类似GALAXY系列，这个品牌是三星去年注册的，未来将包括有智能手机、平板电脑、数码相机等设备。
三星ZEQ9000将搭载高通骁龙800处理器，不过也有说法是搭载三星自家的Exynos处理器，具体未得到官方确认。采用4.8英寸 1280×720像素分辨率屏幕，该机长度为136.1mm，宽度为69.1mm，体积整体与GALAXY S4相似。运行的是Tizen 2.2系统，该系统也会在发布会时被隆重而详细地介绍。
三星已经发出邀请函将在2月23日MWC大会前夕发布这款Tizen手机，除了邀请韩国SK电讯、KT以及LG U+等运营商参与，传闻中国厂商中兴也加入Tizen阵营，推出搭载Tizen的新机型。

中国概念股周五收盘涨跌互现
新浪科技讯 北京时间2月1日凌晨消息 美国股市周五低收，欧元区CPI涨幅的意外下降引发投资者对通货紧缩的恐惧，他们担心通货紧缩将扼杀经济复苏。好于预期的美国消费者开支数据未能提供足够支撑，因为美国人的收入并未增加。美泰、亚马逊、沃尔玛与万事达卡等公司业绩给市场带来压力。
受谷歌上涨以及抄底者入场带动，纳指在下午一度转涨，道指与标准普尔500指数跌幅也有所收窄。值得注意的是，今天美股走势与美元兑日元汇率走势十分相似，二者同时从盘中低点开始反弹，在下午又同时从高点回落。
截至收盘，道琼斯工业平均指数下跌了149.76点，报15698.85点，跌幅为0.94%，道指盘中一度下跌200余点。标准普尔500指数下跌11.61点，报1782.58点，跌幅为0.65%；纳斯达克综合指数下跌了19.25点，报4103.88点，跌幅为0.47%。纳指在稍早时候一度转涨。
中国概念股周五涨跌互现，两只股票涨超5%，汽车之家涨6.5%，网秦涨6%。两只股票跌超5%，中国手游跌5.21%，麦考林(Nasdaq:MCOX)跌12.12%。麦考林昨日宣布，该公司获悉，当前特定股东已于2014年1月29日与商圈网达成了确定的股票收购协议。

One planet, two stars: New research shows how circumbinary planets form

Luke Skywalker's home planet Tatooine would have formed far from its current location in the Star Wars universe, a new University of Bristol study into its real world counterparts, observed by the Kepler space telescope, suggests.
Like the fictional Star Wars planet, Kepler-34(AB)b is a circumbinary planet, so-called because its orbit encompasses two stars. There are few environments more extreme than a binary star system in which planet formation can occur. Powerful gravitational perturbations from the two stars on the rocky building blocks of planets lead to destructive collisions that grind down the material. So, how can the presence of such planets be explained?
In research published this week in Astrophysical Journal Letters, Dr Zoe Leinhardt and colleagues from Bristol's School of Physics have completed computer simulations of the early stages of planet formation around the binary stars using a sophisticated model that calculates the effect of gravity and physical collisions on and between one million planetary building blocks.
They found that the majority of these planets must have formed much further away from the central binary stars and then migrated to their current location.
Dr Leinhardt said: "Our simulations show that the circumbinary disk is a hostile environment even for large, gravitationally strong objects. Taking into account data on collisions as well as the physical growth rate of planets, we found that Kepler 34(AB)b would have struggled to grow where we find it now."
Based on these conclusions for Kepler-34, it seems likely that all of the currently known circumbinary planets have also migrated significantly from their formation locations -- with the possible exception of Kepler-47 (AB)c which is further away from the binary stars than any of the other circumbinary planets.
Stefan Lines, lead author of the study, said: "Circumbinary planets have captured the imagination of many science-fiction writers and film-makers -- our research shows just how remarkable such planets are. Understanding more about where they form will assist future exoplanet discovery missions in the hunt for earth-like planets in binary star systems."

Forensic experts compile guide on how to ID child abuse, starvation
http://feeds.sciencedaily.com/~r/sciencedaily/~3/hro-I2aMH2M/140131101205.htm
Jan 31st 2014, 15:12
Forensic science experts from North Carolina State University are publishing a comprehensive overview of forensic research that can be used to identify child abuse and starvation.
"By pulling all of this information together in one place, we hope that we can save the lives of some children and find justice for others," says Dr. Ann Ross, a professor of anthropology at NC State and lead author of the paper. Ross is also co-editor of the book "The Juvenile Skeleton in Forensic Abuse Investigations."
"For example, we looked at issues of neglect in which children are starved to death," Ross says. "These are supposedly rare, but I've unfortunately seen this a few times in my capacity as an advisor to medical examiners. In this paper we offer some guidelines on how to use the mineral density of bones to determine whether a child was being starved."
Proving that a child was starved to death is difficult; it's essentially impossible to assess normal indicators of starvation once a body has decomposed. But the paper explains that forensic investigators can use a DXA scan, like those used to assess osteoporosis in older adults, to assess bone density and determine whether a child was severely malnourished.
Also, because teeth are not as affected by malnutrition as bones are, investigators can compare the development of an individual's teeth and bones. Stunted growth of a child's tibia can be a strong indicator of starvation, for example.
"These techniques are well-established but are not in widespread use in the United States," Ross says.
"We also combed the existing literature to focus on skeletal injuries that are indicators of abuse and that are unlikely or impossible to be caused by accident," says Dr. Chelsey Juarez, an assistant professor of anthropology at NC State and co-author of the paper.
For example, rib fractures are very rare in accidental trauma, so the presence of rib fractures in children is highly suggestive of abuse.
The paper also offers broader advice, such as noting that forensic investigators should determine whether the story they're getting from a child's caregiver is consistent with the injuries they see on the child.
"The portion of the paper dealing with injuries is particularly important," Juarez says. "Because while it can be used for post-mortem assessment, it can also be used to examine X-rays of living children who can still be saved from abuse."

Latest Science News -- ScienceDaily: How neurons control fine motor behavior of the arm

How neurons control fine motor behavior of the arm
http://feeds.sciencedaily.com/~r/sciencedaily/~3/QkvjJ_CJ92E/140131101201.htm
Jan 31st 2014, 15:12
Motor commands issued by the brain to activate arm muscles take two different routes. As the research group led by Professor Silvia Arber at the University of Basel's Biozentrum and the Friedrich Miescher Institute for Biomedical Research has now discovered, many neurons in the spinal cord send their instructions not only towards the musculature, but at the same time also back to the brain via an exquisitely organized network. This dual information stream provides the neural basis for accurate control of arm and hand movements. These findings have now been published in Cell.
Movement is a fundamental capability of humans and animals, involving the highly complex interplay of brain, nerves and muscles. Movements of our arms and hands, in particular, call for extremely precise coordination. The brain sends a constant stream of commands via the spinal cord to our muscles to execute a wide variety of movements. This stream of information from the brain reaches interneurons in the spinal cord, which then transmit the commands via further circuits to motor neurons innervating muscles. The research group led by Silvia Arber at the Biozentrum of the University of Basel and the Friedrich Miescher Institute for Biomedical Research has now elucidated the organization of a second information pathway taken by these commands.
Cc to the brain: one command -- two directions
The scientists showed that many interneurons in the mouse spinal cord not only transmit their signals via motor neurons to the target muscle, but also simultaneously send a copy of this information back to the brain. Chiara Pivetta, first author of the publication, explains: "The motor command to the muscle is sent in two different directions -- in one direction, to trigger the desired muscular contraction and in the other, to inform the brain that the command has actually been passed on to the musculature." In analogy to e mail transmission, the information is thus not only sent to the recipient but also to the original requester.
Information to brainstem nucleus segregated by function
What happens to the information sent by spinal interneurons to the brain? As Arber's group discovered, this input is segregated by function and spatially organized within a brainstem nucleus. Information from different types of interneurons thus flows to different areas of the nucleus. For example, spinal information that will influence left-right coordination of a movement is collected at a different site than information affecting the speed of a movement.
Fine motor skills supported by dual information stream
Arber comments: "From one millisecond to the next, this extremely precise feedback ensures that commands are correctly transmitted and that -- via the signals sent back to the brain from the spinal cord -- the resulting movement is immediately coordinated with the brain and adjusted." Interestingly, the scientists only observed this kind of information flow to the brain for arm, but not for leg control. "What this shows," says Arber, "is that this information pathway is most likely important for fine motor skills. Compared to the leg, movements of our arm and especially our hands have to be far more precise. Evidently, our body can only ensure this level of accuracy in motor control with constant feedback of information."
In further studies, Silvia Arber's group now plans to investigate what happens if the flow of information back to the brain is disrupted in specific ways. Since some interneurons facilitate and others inhibit movement, such studies could provide additional insights into the functionality of circuits controlling movement.

How neurons control fine motor behavior of the arm
http://feeds.sciencedaily.com/~r/sciencedaily/~3/QkvjJ_CJ92E/140131101201.htm

Motor commands issued by the brain to activate arm muscles take two different routes. As the research group led by Professor Silvia Arber at the University of Basel's Biozentrum and the Friedrich Miescher Institute for Biomedical Research has now discovered, many neurons in the spinal cord send their instructions not only towards the musculature, but at the same time also back to the brain via an exquisitely organized network. This dual information stream provides the neural basis for accurate control of arm and hand movements. These findings have now been published in Cell.
Movement is a fundamental capability of humans and animals, involving the highly complex interplay of brain, nerves and muscles. Movements of our arms and hands, in particular, call for extremely precise coordination. The brain sends a constant stream of commands via the spinal cord to our muscles to execute a wide variety of movements. This stream of information from the brain reaches interneurons in the spinal cord, which then transmit the commands via further circuits to motor neurons innervating muscles. The research group led by Silvia Arber at the Biozentrum of the University of Basel and the Friedrich Miescher Institute for Biomedical Research has now elucidated the organization of a second information pathway taken by these commands.
Cc to the brain: one command -- two directions
The scientists showed that many interneurons in the mouse spinal cord not only transmit their signals via motor neurons to the target muscle, but also simultaneously send a copy of this information back to the brain. Chiara Pivetta, first author of the publication, explains: "The motor command to the muscle is sent in two different directions -- in one direction, to trigger the desired muscular contraction and in the other, to inform the brain that the command has actually been passed on to the musculature." In analogy to e mail transmission, the information is thus not only sent to the recipient but also to the original requester.
Information to brainstem nucleus segregated by function
What happens to the information sent by spinal interneurons to the brain? As Arber's group discovered, this input is segregated by function and spatially organized within a brainstem nucleus. Information from different types of interneurons thus flows to different areas of the nucleus. For example, spinal information that will influence left-right coordination of a movement is collected at a different site than information affecting the speed of a movement.
Fine motor skills supported by dual information stream
Arber comments: "From one millisecond to the next, this extremely precise feedback ensures that commands are correctly transmitted and that -- via the signals sent back to the brain from the spinal cord -- the resulting movement is immediately coordinated with the brain and adjusted." Interestingly, the scientists only observed this kind of information flow to the brain for arm, but not for leg control. "What this shows," says Arber, "is that this information pathway is most likely important for fine motor skills. Compared to the leg, movements of our arm and especially our hands have to be far more precise. Evidently, our body can only ensure this level of accuracy in motor control with constant feedback of information."
In further studies, Silvia Arber's group now plans to investigate what happens if the flow of information back to the brain is disrupted in specific ways. Since some interneurons facilitate and others inhibit movement, such studies could provide additional insights into the functionality of circuits controlling movement.

众所周知，人的记忆力会随着年龄的增长而下降，25岁之后记忆力就开始缓慢衰退。但发表在《Topics in Cognitive Science》上的一篇论文给出了不同解释：老年人反应缓慢不是因为认知能力下降，而是大脑中储存信息太多，他们因此需要更长时间去搜索和处理信息。德国Tübingen大学的一组语言学研究员使用先进的学习模拟去搜索巨大的单词和短语数据库。受过教育的老年人通常比年轻人知道更多词汇，实验模拟长者大脑搜索一个单词，然后加入老年人年轻人之间的词汇量差异，发现记忆力衰退的鸿沟在很大程度上消失了。换句话说，你大脑中储存的信息越多，你寻找特定词汇的时间就越长。论文作者对研究结果也感到震惊。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.

塞浦路斯的Nicosia大学去年宣布允许学生用比特币支付学费，成为世界上第一家接受比特币的私立大学。现在，英国的坎布里亚大学成为第一所接受比特币的公立大学，但用比特币支付学费仅限于两门关于互补货币在经济和社会制度中扮演什么角色的新课程。负责新课程的是 Jem Blendell教授。Blendell教授说，一些人喜欢比特币是因为它的流通速度和安全性。一些人接受它是因为它是金融自由新时代的货币，也有人关注它对经济与社会的影响，还有人认为它在未来会变得更重要。所以他说，要了解更多关于包括比特币在内的互补货币的知识，以及对此进行不同角度的分析，就必须从使用中学习。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.

微信红包或存漏洞：泄露银行卡信息及提现记录
新浪科技讯 1月31日晚间消息，今年春节，微信"抢红包"成为微信朋友的一大热门活动。不过今日有微博网友今日晒出截图称，微信红包存在技术漏洞，会误将绑定的银行卡及红包提现记录错发给好友。这位网友贴出了这一漏洞的聊天截图，并呼吁周边的人解绑微信上的银行卡。
今年春节，微信推出了新年红包功能，用户可通过该功能向好友或者所在的群发送红包。为了发红包和抢红包，微信要求用户把银行卡(非信用卡)绑定到微信上，用户可从银行卡取钱发送红包，或者将收到的红包提现到自己的银行卡。
不过也有部分用户对微信的安全问题也很担心，而今日也有一些用户表示确实遇到了微信账户安全问题。微博认证信息为"《携手闺蜜游世界》系列丛书作者"的网友"娜小鱼儿"今日下午发表微博表示，自己收到一个朋友发来的链接，以为是红包。"结果点开之后看到的全部是他手机里的收红包、发红包记录，还有他的提现记录，而我的任何红包的信息都看不到了。"
"娜小鱼儿"晒出的微信截图显示，她点击了这位好友发来的题为"新年红包"的微信链接后，能够清楚看到这位好友后台的红包信息，连好友提现过几次、提现到哪个银行，银行卡尾号和姓名，提现到账时间等信息都一清二楚。
"娜小鱼儿" 此后又连发了几条微博，表示担心到银行卡安全问题，她和她的那位好友赶紧解除了自己的微信银行卡绑定。(木南)

尼安德特人虽在几万年前就已灭绝，但他们的部分基因组仍然留在走出非洲的现代人类基因组中。根据发表在《科学》的一项研究报告，1000基因组项目分析了来自欧洲和东亚的665名个体的基因组，发现20%的尼安德特人基因组留在现代人类基因中。尼安德特人与现代人祖先有过杂交，因而在基因组中留下了它们遗传物质。根据另一篇发表在《自然》上的尼安德特人基因组分析报告，研究人员在现代人基因组中注意到有大块区域不存在尼安德特人的DNA，暗示尼安德特人基因组序列中的某些部分可能是有害的。他们还观察到现代人基因组中的某些部分所含有的尼安德特人DNA比预计的要多，可能是因为它们赋予了与皮肤表型有关的适应性优势而被留存了下来。研究人员发现，某些尼安德特人基因组能影响皮肤色素，而另一些则会增加糖尿病和狼疮等疾病的风险。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.

比特币中国恢复了人民币存款支付业务。根据Bitcoinity的统计，它的每日交易量超过了火币网成为最大交易平台。中国央行去年12月5日发布了关于禁止国内金融机构交易比特币的通知，为此比特币中国在去年12月曾暂停了人民币存款功能。此举导致比特币中国交易量下降，并连带导致比特币兑换价格从超过一千美元暴跌一半。比特币中国CEO李启元接受电话采访时称，比特币中国在研究了央行的通知以及其他引发对比特币银行活动担忧的规定后，已于周四恢复接受存款。比特币中国认为，虽然银行自身被禁止参与比特币交易和投机活动，但企业银行帐户接受存款并将资金转移到客户帐户上是合法的。 但比特币中国并没有高调宣布这项变动，部分原因是该公司对政府未来的举动持谨慎态度。李启元称，比特币中国绝对遵守了中国央行12月5日所发布通知的内容，但中央政府和相关政府机构在未来任何时候都可能更改规定，所以该交易所决定采取观望态度。他说，时机也很重要。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.

新华网沈阳1月31日电(彭卓、张逸飞)随着"免费打车"返现活动的刺激，打车软件如今在全国多地迅速蹿红。记者采访发现，打车软件虽省钱实惠、方便快捷，但其暗藏的危险驾驶和助推黑车生意等问题，也不容忽视。
近日，记者乘坐一辆装有打车软件的出租车，途中司机边开车，边盯手机屏幕，准备随时点击"抢单"。记者细心统计，15分钟的路程中，司机几乎每十几秒就要盯手机一眼，途中甚至低头抢单，吓得一旁的记者不得不紧盯路况，以便出现突发情况能及时提醒。
我国《道路交通安全法》明文规定，行车过程中驾驶员严禁使用一切移动通讯设备。乘客李涛表示，按照这一规定，司机使用手机"抢单"应当属于交通违法行为。他表示，看到载自己的司机开车不专心，心里非常忐忑。"安全出行靠司机，的哥却视驾驶规定为儿戏，只为抢单赚钱。碰到这种情况，我投诉可能引来不愉快，不投诉还觉得憋屈。看来真要考虑是否还继续打车！"
此外，打车软件客观上为黑车顺利营运创造条件。几天前，记者曾用打车软件叫车，结果一辆黑车应征成功。沈阳旭龙出租车公司网络主管陈晓东介绍，打车软件没有出现时，黑车拉客有很大的随机性。"但黑车司机使用软件回应乘客的叫车需求后，等于他们之间有了提前的约定，使拉车的成功率更大。"
"快的"公司沈阳分店公关总监叶耘指出，虽有司机客户认证机制，要求必须上传身份证照片、服务监督卡、营运车辆照片等认证材料，但不排除司机个人伪造认证材料的可能。"还有出租车司机虽然申请证件是真的，但是工作外时间，他们也可以利用打车软件开黑车做几单生意。"叶耘表示，如果接乘客的是"黑车"，客户可以在软件里举报司机用户。
陈晓东说，由于打车软件没有获得官方认证，存在法律争议，因此用这些打车软件打车，一旦出现纠纷或事故，理赔难度较大。"出租公司虽很难禁止司机用软件，但对这种行为并不鼓励。"

直逼平板的超大黑钻屏幕
外形设计上两款手机截然不同，当然最明显的就是屏幕尺寸；作为一款绝对的跨界类产品，酷派大神的7英寸外形直逼iPad mini或者三星GALAXY Tab这样的通话平板，视野范围极其广阔，而屏幕也不小的小米3在它面前就显得非常迷你了。
酷派大神与小米手机3
屏幕表现方面，酷派大神的屏幕像素密度也达到了323ppi，效果足够细腻。在我们此前针对酷派大神屏幕进行的专项测试中可以看到，酷派大神在灰阶、色彩渐进等方面表现都很出色，同时拥有极大的可视角度，屏幕色彩表现生动，整体来说让人无可挑剔。

CoolLife UI 5.5对比MIUI V5
系统部分酷派大神与小米手机3均采用了基于Android 4.2二次开发的系统，而且Coollife UI以及小米MIUI V5都已经是我们非常熟悉的；不过此次酷派大神在搭载Android 4.2系统的同时植入了最新版的CoolLife UI 5.5操作界面，相对于4.X的版本来说改动非常大，让我们来详细了解一下。
CoolLife UI 5.5对比MIUI V5
酷派大神的Coollife UI 5.5操作界面采用了主屏+二级应用程序菜单的逻辑机制，因此主屏以及其他几个分屏幕都可以用来放置非常多的桌面插件，来实现对大屏的广泛利用；第一印象上酷派大神Coollife UI 5.5应用到了非常多以往所没有的动态效果。
而小米3的MIUI则是类似iPhone iOS那样所有程序icon全部位于主屏没有二级菜单的设计，因此限制了不少桌面插件的使用。而且从屏幕大小上来说，单个主屏所容纳的内容也没有酷派大神多。
酷派大神Coollife UI 此次设计的桌面插件还是让人眼前一亮的，一改原生Android系统比较鸡肋既不好看也不实用的插件，Coollife UI 5.5当中的日历、音乐、天气甚至应用市场等插件都加入了非常多的动态效果，审美也较之前更加出色；而且像音乐、应用市场等这些插件也都与系统进行了深入开发，可以直接在插件上面完成各种简单操作。
作为7英寸大屏的机型来说，Coollife当中的分屏功能实现了对单一屏幕的多重使用，通过桌面上呼出的分屏菜单，我们可以在酷派大神上面将两个窗口放置排列在同一屏幕上，聊天的同时看视频、淘宝的同时收邮件，可以很好的提高效率。
多媒体播放能力对比
至于多媒体应用方面，我们通过15段1080p视频测试后的结果，除了两段视频无法播放、需要借助第三方播放器软解才能正常播放之外，其他几段不同封装格式、不同编码码率的视频都能够通过酷派大神自带的播放器流畅播放。

与之类似的，小米3也同样对这两段视频无法使用原生播放器正常播放，而对其他剩下的13段视频原生支持良好。
小米3多媒体播放能力
除了格式支持之外，值得一提的是酷派大神采用了杜比7.1环绕声技术，同时在机身顶部与底部配有双立体声喇叭，无论是音乐外放还是横屏观看视频，酷派大神都能为用户带来身临其境的体验。而且酷派大神也能够支持分屏视频以及浮窗视频的多种方式，满足你不同使用场景下的需要。

1300万同像素级别拍照对比
拍照方面，酷派大神配备索尼堆栈式1300万像素摄像头，有着28毫米超大广角，后置双LED补光灯，前置摄像头也是达到了500万像素。此外还拥有包括轨迹拍照、路人移除、美容拍照等共计九种拍照模式。
而小米手机3在拍照方面的基本功能、设置也都比较全面，拥有美颜模式等拍照功能，但总体并不如酷派大神丰富。

焦距：4mm 光圈：f/2.2 ISO感光度：320
曝光时间：1/50 曝光补偿：0EV 白平衡：自动
真八核性能对比Tegra 4
最后让我们来实际对比一下酷派大神以及小米3的性能水准；其中酷派大神采用联发科8核心处理器，CPU部分为Cortex-A7架构1.7GHz主频、GPU部分为Mali-450MP，而小米3(这里为TD版)则采用Tegra 4处理器，CPU部分为Cortex-A15架构1.8GHz主频，GPU部分为72核心NVIDIA GeForce。
AnTuTu Benchmark是一个专门给Android系统的手机、平板电脑硬件跑分的软件，它能一键运行完整测试项目，通过内存性能、CPU整数性能，CPU浮点性能、2D、3D绘图性能、数据库I/O、SD卡读、写速度等多项性能测试，并对手机的整体和单项硬件性能做出评分。同时上传分数并查看该设备在世界的排名。
Vellamo是由Qualcomm(高通公司)开发的一个基准测试应用(类似于Neocore)，它可以让你对手机浏览器的性能及稳定性进行测试，包括像Java脚本性能、渲染、联网和用户界面等。该工具的结果同样包括多个子项，但我们只取总成绩，分数越高则表明手机对浏览器的优化程度越高，网页浏览体验更好。
Vellamo作为一种手机网页标尺工具，如今已扩展至包括两个主要模块。HTML5模块可用来评估移动网页浏览器性能，而Metal模块可对移动处理器的CPU子系统性能进行测量。测试套件点击即用，方便快捷，分模块进行管理，Vellamo可对滚动缩放，3D图形，视频性能，内存读写，带宽峰值性能等诸多方面进行评估。
总的来说酷派大神的性能从跑分上来看还是略逊于小米手机3，差别在于MT6592的微架构还是落后于小米3的Tegra 4，虽然核心数量众多但是总体效能不高。不过MT6592的Cortex-A7相比A15来说也具备省电等特性，况且两万七左右的跑分在我们之前的各项测试当中也足够胜任绝大多数应用，因此实际体验来说两者的性能差距并不大。

对于酷派大神和小米3这两款机型来说，屏幕方面的对决酷派大神无疑更具优势，7英寸的超大屏幕更是让其成为了一部跨界机型，在性能方面，酷派大神也没有太落下风，在整体体验方面保持了很高的水准。在系统方面，酷派最新推出CoolLife UI 5.5更有着自己独到之处，可以说和MIUI不分上下，这方面只能看个人喜欢及习惯来决定。酷派大神可以说是酷派在市场转型上的代表作，无论是外观设计、硬件配置和价格来说，我们都能看到酷派满满的诚意。
Android频道评测编辑：常亮
这两款产品的售价比较贴近，因此消费者相对来说较难选择，不过两款产品的特色还是比较明显的。酷派大神拥有智能手机行业最大尺寸的屏幕，在观影、娱乐等方面拥有一定的视觉冲击感。而在性能上，虽然联发科MT6592与英伟达Tegra 4相比还有小幅差距，不过对于千元级别的消费者而言，基本可以忽略。当然便携性方面小米手机3显然要更胜一筹，不过本着买新不买旧的原则，酷派大神还是一款值得期待的产品。
Android频道评测编辑：毛文婷
如今高性价比市场不再是小米的天下了，酷派大神就是一个很好的例子。两款产品价位相近，而酷派大神则为用户提供了更大的屏幕，并通过全贴合技术带来了更好的视觉效果。硬件方面八核与四核之间的对比确实不能用核心数量的多少来衡量，MT6592虽然相比Tegra4仍有差距，但对大部分用户来说已经足够。如果你预算有限又倾向于大屏产品，那么酷派大神无疑比小米3要更适合你。
网友问答：
酷派大神与小米手机3
1、酷派大神与小米手机3各有哪些独到卖点？
对于酷派大神来说当然首先是屏幕，除了尺寸够大之外，与iPhone师出同门的LTPS技术让其显示效果非常出色，结合7.1声道的双扬声器影音效果非凡。此外CoolLife UI 5.5目前也足够成熟，次旗舰级别的性能也让其具备十足的性价比。小米手机3外观设计相比之前也有很大进步，Tegra4处理器的采用也映射着发烧友的定位，外观、性能、功能几方面虽然整体比较均衡但缺乏亮点。
2、CoolLife UI 5.5与小米MIUI V5谁更好用？
2013年国产手机厂商不仅敢于抢旗舰硬件平台，对于软件系统的精耕细作也是有目共睹的；我们可能更加久的熟悉MIUI，CoolLife的进步可能是酷派老用户才看得到的，但是后者相比前一版本无论在外观、还是插件以及最终的功能上面都堪称质的飞跃，易用性上面也足以媲美以流畅和易用著称已久的MIUI。
3、111元差价的两款产品谁更具性价比？
各方面的对比来看两者很难拉开差距，于是可以从你的具体需求以及两款机器的各自卖点出发来寻找自己的性价比之选；比如酷派大神有着小米3无法比拟的视觉及多媒体优势，续航方面也更胜一筹；小米3则依然维持性能发烧友的定位，对于性能有着极致追求的用户可以选择。
酷派大神与小米手机3对比
对比总结：
2013年的国产手机市场竞争越来越白热化，不仅议价能力的提高使得3000元以上的价位有众多精品显现，更精彩的还是在于2000元左右的平民价位的激烈竞争；如果说几个月之前小米3尚且能够凭借Tegra4平台赢得高性价比的称号，那么在MT6592诞生之后众多国产厂商纷纷觊觎这一性能强大又容易塑造高性价比的平台，我们也很欣慰的看到这样一款7英寸屏幕、金属材质做工、拥有更加出色的CoolLife UI的酷派大神的诞生，在屏幕、外观以及系统新鲜程度方面，酷派大神都要相比小米3更加出色，而CoolLife的蜕变也足以媲美MIUI。

CoolLife UI 5.5对比MIUI V5
酷派大神的Coollife UI 5.5操作界面采用了主屏+二级应用程序菜单的逻辑机制，因此主屏以及其他几个分屏幕都可以用来放置非常多的桌面插件，来实现对大屏的广泛利用；第一印象上酷派大神Coollife UI 5.5应用到了非常多以往所没有的动态效果。
而小米3的MIUI则是类似iPhone iOS那样所有程序icon全部位于主屏没有二级菜单的设计，因此限制了不少桌面插件的使用。而且从屏幕大小上来说，单个主屏所容纳的内容也没有酷派大神多。
酷派大神Coollife UI 此次设计的桌面插件还是让人眼前一亮的，一改原生Android系统比较鸡肋既不好看也不实用的插件，Coollife UI 5.5当中的日历、音乐、天气甚至应用市场等插件都加入了非常多的动态效果，审美也较之前更加出色；而且像音乐、应用市场等这些插件也都与系统进行了深入开发，可以直接在插件上面完成各种简单操作。
作为7英寸大屏的机型来说，Coollife当中的分屏功能实现了对单一屏幕的多重使用，通过桌面上呼出的分屏菜单，我们可以在酷派大神上面将两个窗口放置排列在同一屏幕上，聊天的同时看视频、淘宝的同时收邮件，可以很好的提高效率。
多媒体播放能力对比
至于多媒体应用方面，我们通过15段1080p视频测试后的结果，除了两段视频无法播放、需要借助第三方播放器软解才能正常播放之外，其他几段不同封装格式、不同编码码率的视频都能够通过酷派大神自带的播放器流畅播放。

与之类似的，小米3也同样对这两段视频无法使用原生播放器正常播放，而对其他剩下的13段视频原生支持良好。

除了格式支持之外，值得一提的是酷派大神采用了杜比7.1环绕声技术，同时在机身顶部与底部配有双立体声喇叭，无论是音乐外放还是横屏观看视频，酷派大神都能为用户带来身临其境的体验。而且酷派大神也能够支持分屏视频以及浮窗视频的多种方式，满足你不同使用场景下的需要。

1300万同像素级别拍照对比
拍照方面，酷派大神配备索尼堆栈式1300万像素摄像头，有着28毫米超大广角，后置双LED补光灯，前置摄像头也是达到了500万像素。此外还拥有包括轨迹拍照、路人移除、美容拍照等共计九种拍照模式。
而小米手机3在拍照方面的基本功能、设置也都比较全面，拥有美颜模式等拍照功能，但总体并不如酷派大神丰富。
焦距：4mm 光圈：f/2.2 ISO感光度：135
曝光时间：1/939 曝光补偿：0EV 白平衡：自动
焦距：4mm 光圈：f/2.2 ISO感光度：100

曝光时间：1/476 曝光补偿：0EV 白平衡：自动
焦距：4mm 光圈：f/2.2 ISO感光度：187
曝光时间：1/50 曝光补偿：0EV 白平衡：自动
焦距：4mm 光圈：f/2.2 ISO感光度：320
曝光时间：1/50 曝光补偿：0EV 白平衡：自动
真八核性能对比Tegra 4
最后让我们来实际对比一下酷派大神以及小米3的性能水准；其中酷派大神采用联发科8核心处理器，CPU部分为Cortex-A7架构1.7GHz主频、GPU部分为Mali-450MP，而小米3(这里为TD版)则采用Tegra 4处理器，CPU部分为Cortex-A15架构1.8GHz主频，GPU部分为72核心NVIDIA GeForce。
AnTuTu Benchmark是一个专门给Android系统的手机、平板电脑硬件跑分的软件，它能一键运行完整测试项目，通过内存性能、CPU整数性能，CPU浮点性能、2D、3D绘图性能、数据库I/O、SD卡读、写速度等多项性能测试，并对手机的整体和单项硬件性能做出评分。同时上传分数并查看该设备在世界的排名。
Vellamo是由Qualcomm(高通公司)开发的一个基准测试应用(类似于Neocore)，它可以让你对手机浏览器的性能及稳定性进行测试，包括像Java脚本性能、渲染、联网和用户界面等。该工具的结果同样包括多个子项，但我们只取总成绩，分数越高则表明手机对浏览器的优化程度越高，网页浏览体验更好。
Vellamo作为一种手机网页标尺工具，如今已扩展至包括两个主要模块。HTML5模块可用来评估移动网页浏览器性能，而Metal模块可对移动处理器的CPU子系统性能进行测量。测试套件点击即用，方便快捷，分模块进行管理，Vellamo可对滚动缩放，3D图形，视频性能，内存读写，带宽峰值性能等诸多方面进行评估。
总的来说酷派大神的性能从跑分上来看还是略逊于小米手机3，差别在于MT6592的微架构还是落后于小米3的Tegra 4，虽然核心数量众多但是总体效能不高。不过MT6592的Cortex-A7相比A15来说也具备省电等特性，况且两万七左右的跑分在我们之前的各项测试当中也足够胜任绝大多数应用，因此实际体验来说两者的性能差距并不大。

2100万像素？疑似三星Galaxy S5摄像头样张曝光

我们知道接下来这张图片可能会让人觉得奇怪甚至是难以接受，但我们还是建议你仔细看看——这张可能是被谁用手指遮住摄像头拍下的图片，来自三星Galaxy S5。这张神秘的照片是在20天前通过Flipboard被一个名为@123fliptest的用户上传。
很明显，我们当然不是在鉴定一张摄影杰作，那根本不重要。真正有趣的是，根据嵌入的EXIF数据显示，这张图片是由三星SM-G900-V型号拍摄。目前尚未公布的Galaxy S5的SM-G900已经有了多个版本，而看起来G900-V是即将公布的型号。
继续深入研究这张照片EXIF数据的话，可以发现图片的分辨率为5312×2988，我们由此猜测三星Galaxy S5的摄像头可能有1600万像素。不过，由于这张图是被截成16：9的比例，所以有可能并不是手机摄像头原本的图片比例。因此Galaxy S5有可能搭配的是4:3感应器，所以该手机的实际摄像头像素可能达到2100万。
Galaxy S5预计将于今年2月或3月发布，最有可能的时间是MWC2014，让我们静候佳音。

Latest Science News -- ScienceDaily: Cell cycle speed is key to making aging cells young again
Latest Science News -- ScienceDaily
Breaking science news and articles on global warming, extrasolar planets, stem cells, bird flu, autism, nanotechnology, dinosaurs, evolution -- the latest discoveries in astronomy, anthropology, biology, chemistry, climate and environment, computers, engineering, health and medicine, math, physics, psychology, technology, and more -- from the world's leading universities and research organizations.
Cell cycle speed is key to making aging cells young again
http://feeds.sciencedaily.com/~r/sciencedaily/~3/KG1szytCnBw/140130121609.htm

A fundamental axiom of biology used to be that cell fate is a one-way street -- once a cell commits to becoming muscle, skin, or blood it always remains muscle, skin, or blood cell. That belief was upended in the past decade when a Japanese scientist introduced four simple factors into skin cells and returned them to an embryonic-like state, capable of becoming almost any cell type in the body.
Hopeful of revolutionary medical therapies using a patient's own cells, scientists rushed to capitalize on the discovery by 2012 Nobel Laureate Shinya Yamanaka. However, the process has remained slow and inefficient, and scientists have had a difficult time discovering a genetic explanation of why this should be.
In the Jan. 30 issue of the journal Cell, Yale School of Medicine researchers identified a major obstacle to converting cells back to their youthful state -- the speed of the cell cycle, or the time required for a cell to divide.
When the cell cycle accelerates to a certain speed, the barriers that keep a cell's fate on one path diminish. In such a state, cells are easily persuaded to change their identity and become pluripotent, or capable of becoming multiple cell types.
"One analogy may be that when temperature increases to sufficient degrees, even a very hard piece of steel can be malleable so that you can give it a new shape easily," said Shangqin Guo, assistant professor of cell biology at the Yale Stem Cell Center and lead author of the paper. "Once cells are cycling extremely fast, they do not seem to face the same barriers to becoming pluripotent."
Guo's team studied blood-forming cells, which when dividing undergo specific changes in their cell cycle to produce new blood cells. Blood-forming progenitor cells normally produce only new blood cells. However, the introduction of Yamanaka factors sometimes -- but not always -- help these blood-forming cells become other types of cells. The new report finds that after this treatment blood-forming cells tend to become pluripotent when the cell cycle is completed in eight hours or less, an unusual speed for adult cells. Cells that cycle more slowly remain blood cells.
"This discovery changes the way people think about how to change cell fate and reveals that a basic 'house-keeping' function of a cell, such as its cell cycle length, can actually have a major impact on switching the fate of a cell," said Haifan Lin, director of the Yale Stem Cell Center.
The study has other implications than explaining the bottleneck in reprogramming that makes it difficult to produce individualized pluripotent stem cells for research and therapy. Shangqin Guo noted that many human diseases are associated with abnormalities in establishing proper cell identity as well as abnormalities in cell cycle behavior.

Nearly everyone uses piezoelectrics: Now scientists know more about how they actually work

Piezoelectrics -- materials that can change mechanical stress to electricity and back again -- are everywhere in modern life. Computer hard drives. Loud speakers. Medical ultrasound. Sonar. Though piezoelectrics are a widely used technology, there are major gaps in our understanding of how they work. Now researchers at the National Institute of Standards and Technology (NIST) and Canada's Simon Fraser University believe they've learned why one of the main classes of these materials, known as relaxors, behaves in distinctly different ways from the rest and exhibit the largest piezoelectric effect. And the discovery comes in the shape of a butterfly.
The team examined two of the most commonly used piezoelectric compounds -- the ferroelectric PZT and the relaxor PMN -- which look very similar on a microscopic scale. Both are crystalline materials composed of cube-shaped unit cells (the basic building blocks of all crystals) that contain one lead atom and three oxygen atoms. The essential difference is found at the centers of the cells: in PZT these are randomly occupied by either one zirconium atom or one titanium atom, both of which have the same electric charge, but in PMN one finds either niobium or manganese, which have very different electric charges. The differently charged atoms produce strong electric fields that vary randomly from one unit cell to another in PMN and other relaxors, a situation absent in PZT.
"PMN-based relaxors and ferroelectric PZT have been known for decades, but it has been difficult to identify conclusively the origin of the behavioral differences between them because it has been impossible to grow sufficiently large single crystals of PZT," says the NIST Center for Neutron Research (NCNR)'s Peter Gehring. "We've wanted a fundamental explanation of why relaxors exhibit the greatest piezoelectric effect for a long time because this would help guide efforts to optimize this technologically valuable property."
A few years ago, scientists from Simon Fraser University found a way to make crystals of PZT large enough that PZT and PMN crystals could be examined with a single tool for the first time, permitting the first apples-to-apples comparison of relaxors and ferroelectrics. That tool was the NCNR's neutron beams, which revealed new details about where the atoms in the unit cells were located. In PZT, the atoms sat more or less right where they were expected, but in the PMN, their locations deviated from their expected positions -- a finding Gehring says could explain the essentials of relaxor behavior.
"The neutron beams scatter off the PMN crystals in a shape that resembles a butterfly," Gehring says. "It gives a characteristic blurriness that reveals the nanoscale structure that exists in PMN -- and in all other relaxors studied with this method as well -- but does not exist in PZT. It's our belief that this butterfly-shaped scattering might be a characteristic signature of relaxors."
Additional tests the team performed showed that PMN-based relaxors are over 100 percent more sensitive to mechanical stimulation compared to PZT, another first-time measurement. Gehring says he hopes the findings will help materials scientists do more to optimize the behavior of piezoelectrics generally.

Researchers develop new tool to identify genetic risk factors

Dartmouth researchers developed a new biological pathway-based computational model, called the Pathway-based Human Phenotype Network (PHPN), to identify underlying genetic connections between different diseases as reported in BioDataMining this week. The PHPN mines the data present in large publicly available disease datasets to find shared SNPs, genes, or pathways and expresses them in a visual form.
"The PHPN offers a bird's eye view of the diseases and phenotype's relationships at the systems level," said Christian Darabos, PhD, post-doctoral fellow, Institute for Quantitative Biomedical Sciences (iQBS), Dartmouth College.
The PHPN uses information in human disease networks in conjunction with network science tools to show clusters of related disorders sharing common genetic backgrounds. It does so without the typical clinical classification of disease, in which all heart disease or all cancers are grouped together, based on clinical presentation. Dartmouth geneticists instead rely on the information contained in the PHPN's topology to automatically classify traits and diseases by their shared genetic mechanisms, such as common genes or pathways. PHPN explores the connections between the layers of the networks to find patterns and relationships.
"The intuitive network representation of the knowledge mined from several large-scale datasets makes the information accessible to anyone. It lies at the crossroads of computational genetics, systems biology, information theory, and network science," Darabos said.
PHPN supports the integration of genomic and phenotypic data to uncover significant links between traits, attributes, and disease. This offer tremendous potential in identifying risk factors for certain diseases. At the same time, it can reveal important targets for therapeutic intervention.
"As a proof of concept, the PHPN has proven capable of identifying well documented interactions, and many novel links that remain to be explored in depth," said Darabos.
The PHPN reveals biological connections between seemingly disparate displays of genetic properties and offers a unique view of the architecture of disease.
This tool can help researchers identify areas for further investigation based on connections it uncovers. "The PHPN is a hypothesis-generating tool, potentially capable of identifying yet uncharacterized common drug targets," said Darabos.
As a next step, iQBS researchers will refine statistical methods, isolate networks for optimal results, and compare previous work on phenotype networks.

对毒品生产销售真正产生革命性影响不是丝绸之路而是开放互联网。借助互联网，几乎任何具有基本化学知识的人都可以设计、生产和销售毒品。而且在大多数情况下，警察根本无力阻止你。2009年，欧洲毒品和毒品滥用监视中心识别出了24种新毒品；2010年，识别出了41种；2011年是49种，2012年是73种；截至2013年10月，已发现了56种新毒品。不断出现的新毒品令国际毒品监控系统应接不暇。Mike Power在medium上发表文章，介绍如何设计出一种新的合法兴奋剂，并通过互联网找到中国的一个实验室去制造它。来自中国的内部人士称，中国的化学工业基本上不受监管，这是数十起公共健康丑闻发生的原因之一。作者称，仅仅两周时间，中国的实验室就生产出了纯度为93.7%的兴奋剂。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.

对毒品生产销售真正产生革命性影响不是丝绸之路而是开放互联网。借助互联网，几乎任何具有基本化学知识的人都可以设计、生产和销售毒品。而且在大多数情况下，警察根本无力阻止你。2009年，欧洲毒品和毒品滥用监视中心识别出了24种新毒品；2010年，识别出了41种；2011年是49种，2012年是73种；截至2013年10月，已发现了56种新毒品。不断出现的新毒品令国际毒品监控系统应接不暇。Mike Power在medium上发表文章，介绍如何设计出一种新的合法兴奋剂，并通过互联网找到中国的一个实验室去制造它。来自中国的内部人士称，中国的化学工业基本上不受监管，这是数十起公共健康丑闻发生的原因之一。作者称，仅仅两周时间，中国的实验室就生产出了纯度为93.7%的兴奋剂。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1月30日晚间消息，京东今天向美国证券交易委员会提交IPO(首次公开招股)申请，计划赴美上市，最多融资15亿美元。
以下为招股书概要主要内容：
业务概况
以2012年和2013年前9个月的交易量来看，我们(指京东，编者注)是中国最大的在线直销公司，根据艾瑞的数据2013年第三季度在中国市场的份额为45%。我们的总成交额(GMV)从2011年的327亿元人民币增长至2012年的733亿元人民币，以及2013年前9个月的864亿元人民币(约合141亿美元)。
我们向用户提供愉悦的在线零售体验。通过内容丰富、对用户友好的网站www.jd.com和移动应用，我们以有竞争力的价格提供广泛的正牌产品选择，以及快速可靠的发货服务。我们同时提供便捷的在线及人工支付选择，以及综合性售后服务。为了更好地掌握交付，确保消费者满意度，我们建设了全国性的交付基础设施，以及由自己员工组成的"最后一英里"送货网络。这支撑了我们的在线直销和在线市场业务。在发展在线直销业务的过程中，我们还与供货商建立了强有力的关系。利用我们的优势，我们2010年启动了在线市场业务，使我们可以大幅扩大所提供的产品和服务选择。
由于提供了优秀的用户体验，我们的业务已实现快速增长。我们提供的产品数量从2011年12月31日的约150万种库存单位(SKU)增长至2012年12月31日的约720万种库存单位，以及2013年12月31日的约2570万种库存单位。我们打造了用户互动社区，用于讨论、评级及评测我们的产品和服务。我们相信，在中国所有在线直销公司中，我们拥有最庞大的产品评测数据库，其中包含消费者到目前为止撰写的约2.47亿条产品评测。2011年、2012年，以及2013年前9个月，我们的活跃帐户数分别为1250万、2930万和3580万，而完成交付的订单数分别为6590万、1.938亿和2.117亿。
及时而可靠的交付是在线零售业务成功的关键。考虑到中国第三方交付服务在仓库、物流设施和"最后一英里"送货服务方面的欠发达状况，我们于2007年做出战略决策，自主建设并运营全国性的交付基础设施。我们相信，在中国所有电子商务公司中，我们拥有规模最大的交付基础设施。截至2013年12月31日，我们在全国34座城市运营着82家仓库，总楼层面积超过130万平方米；在全国460座城市拥有1453个送货站和209个提货站；拥有18005名送货人员、8283名仓库人员和4842名客服人员。利用这一全国性的交付基础设施，我们能将大部分订单直接送至客户手中，其中超过一半的订单能在当日或次日送达。截至2013年12月31日，我们在中国31座城市提供了基于211项目的当日送达快递服务，并在206座城市提供了次日送达快递服务。
我们是一家由技术驱动的公司，大力投资开发自主的、易于扩大规模的私有技术平台，以支撑我们的快速增长，帮助我们提供增值技术服务。我们的技术平台目前每天能处理多达3000万个订单，并记录15亿库存单位的状态信息。此外，我们精密的商业情报系统帮助我们改进商品采购策略，以管理库存周转、控制成本，利用大型客户数据库提供订制的产品推荐，以及高性价比、目标性强的广告服务。
我们于2010年10月推出了在线市场，以利用我们的品牌认知度、基数庞大并仍在增长的客户基础、广泛的交易数据、交付基础设施和私有的技术平台。在线市场使我们可以向用户提供更丰富的产品选择。截至2013年12月31日，在线市场占我们网站2570万库存单位的2350万。根据艾瑞的数据，2013年第三季度，在线直销和市场业务使我们成为中国第二大B2C电子商务公司，按交易量来看市场份额为17.5%。我们吸引并选择第三方卖家，通过我们的在线市场向用户提供正牌商品。我们密切监控在线市场第三方卖家的表现和活动，确保他们符合我们对正价商品和高质量客户服务的要求。除了基本交易流程和收款服务外，我们还向第三方卖家提供交付和其他增值服务包。
我们的业务近几年实现了大幅增长。我们的总净营收从2011年的211亿元人民币增长至2012年的414亿元人民币，并从2012年前9个月的288亿元人民币增长至2013年前9个月的492亿元人民币(约合80亿美元)。我们的净亏损2011年和2012年分别为13亿元人民币和17亿元人民币。2013年前9个月，我们的净利润为6000万元人民币(约合1000万美元)，而2012年前9个月为净亏损14亿元人民币。
行业概况
随着居民可支配收入的增长，以及城镇化的加速，中国的零售行业经历了巨大发展。数据显示，中国社会零售总额已经从2008年的人民币6.2万亿元，增长至2012年的9.8万亿元，年复合增长率达12.2%。
但是，中国幅员辽阔，人口众多，消费者行为和购买力千差万别，对零售商的扩大规模和全国扩张形成了重大挑战。结果，中国的零售行业高度碎片化；2012年，中国排名前20位的零售商一共仅占据大约10%的市场份额，而在美国，这一数字约为40%。中国支离破碎的线下零售市场，为线上零售商创造了机会。
艾瑞咨询的数据显示，2012年中国在线零售市场的交易额为人民币1.3万亿元，2016年有望达到3.6万亿元，年复合增长率达28.9%，远超线下零售行业。
在线直销和在线集市是中国在线零售行业的两种主要模式。在线直销模式的含义是，一家公司自行采购、管理库存，通过网络直接向消费者销售商品，并提供送货和售后服务。在线集市模式的含义是，一家公司充当中介平台，撮合不同商家与消费者之间的交易。一些在线集市是由同时开展在线直销业务的公司所掌控的。最初，中国的在线零售市场被在线集市模式所统治；但那些采购精准、物流快捷的在线直销公司在过去几年间也取得了成功，部分原因是消费者越来越关注产品真伪，更注重服务品质。
由于缺少合格的仓储空间和价格合理的"最后一公里"物流服务，送货仍然是在线零售公司面临的一大挑战，服务全国消费者与保持服务品质和效率难以兼顾。(维金 彦飞)

京东起源于2004年1月刘强东建立的一个在线零售网站，自2011年起，该公司经历了来自数家股东的多次融资。
2011年，京东通过普通股的发行融资62.37亿元。其中2011年4月，DST Global以约2亿美元的价格收购了3982.1655万股。
2012年，京东通过普通股的发行、短期银行贷款及行使认股权证融资28.54亿元。
在截至2013年9月30日的2013年前三季度，京东通过发行普通股融资18.5500亿元(合3.03亿美元)，其中部分被偿还短期银行贷款的支出抵消。
京东的历史，开始于2004年1月，创始人刘强东建立了一个电子商务网站，并随后在北京、上海分别创建了他的两家在线零售行业公司。2006年11月，刘强东等人在英属维尔京群岛(British Virgin Islands)组建了海外控股公司Star Wave Investments Holdings Limited，以促进国际融资。该公司随后在2014年1月改名为360buy京东公司。360buy京东公司迁至开曼群岛，依开曼群岛法律成为一家豁免公司，并更名为JD.com公司。
2007年4月，该公司在中国创建了全资子公司北京京东世纪贸易有限公司，简称京东世纪，并从刘强东最初创建的两家公司收购了特定知识产权，这两家公司随后停止运营并解散。京东世纪从此在中国建立了一系列从事批发零售、物流快递、产品研发和互联网金融的子公司。

Dinosaur fossils from China help researchers describe new 'Titan'

A team led by University of Pennsylvania paleontologists has characterized a new dinosaur based on fossil remains found in northwestern China. The species, a plant-eating sauropod named Yongjinglong datangi, roamed during the Early Cretaceous period, more than 100 million years ago. This sauropod belonged to a group known as Titanosauria, members of which were among the largest living creatures to ever walk the earth.
At roughly 50-60 feet long, the Yongjinglong individual discovered was a medium-sized Titanosaur. Anatomical evidence, however, points to it being a juvenile; adults may have been larger.
The find, reported in the journal PLOS ONE, helps clarify relationships among several sauropod species that have been found in the last few decades in China and elsewhere. Its features suggest that Yongjinglong is among the most derived, or evolutionarily advanced, of the Titanosaurs yet discovered from Asia.
Doctoral student Liguo Li and professor Peter Dodson, who have affiliations in both the School of Veterinary Medicine's Department of Animal Biology and the School of Arts and Sciences' Department of Earth and Environmental Science, led the work. They partnered with Hailu You, a former student of Dodson's, who now works at the Chinese Academy of Sciences' Institute of Vertebrate Paleontology and Paleoanthropology, and Daqing Li of the Gansu Geological Museum in Lanzhou, China.
Until very recently, the United States was the epicenter for dinosaur diversity, but China surpassed the U.S. in 2007 in terms of species found. This latest discovery was made in the southeastern Lanzhou-Minhe Basin of China's Gansu Province, about an hour's drive from the province's capital, Lanzhou. Two other Titanosaurs from the same period, Huanghetitan liujiaxiaensis and Daxiatitan binglingi, were discovered within the last decade in a valley one kilometer from the Yongjinglong fossils.
"As recently as 1997 only a handful of dinosaurs were known from Gansu," Dodson said. "Now it's one of the leading areas of China. This dinosaur is one more of the treasures of Gansu."
During a trip to Gansu, Liguo Li was invited to study the remains, which had been in storage since being unearthed in 2008. They consisted of three teeth, eight vertebrae, the left shoulder blade, and the right radius and ulna.
The anatomical features of the bones bear some resemblance to another Titanosaur that had been discovered by paleontologists in China in 1929, named Euhelopus zdanskyi. But the team was able to identify a number of unique characteristics.
"The shoulder blade was very long, nearly 2 meters, with sides that were nearly parallel, unlike many other Titanosaurs whose scapulae bow outward," Li said.
The scapula was so long, indeed, that it did not appear to fit in the animal's body cavity if placed in a horizontal or vertical orientation, as is the case with other dinosaurs. Instead, Li and colleagues suggest the bone must have been oriented at an angle of 50 degrees from the horizontal.
In addition, an unfused portion of the shoulder blade indicated to the researchers that the animal under investigation was a juvenile or subadult.
"The scapula and coracoid aren't fused here," Li said. "It is open, leaving potential for growth."
Thus, a full-grown adult might be larger than this 50-60 foot long individual. Future finds may help elucidate just how much larger, the researchers noted.
The ulna and radius were well preserved, enough so that the researchers could identify grooves and ridges they believe correspond with the locations of muscle attachments in the dinosaur's leg.
The researchers were also able to draw evidence about the dinosaur's relationship to other species from the vertebrae, one of which was from the neck and the other seven from the trunk. Notably, the vertebrae had large cavities in the interior that the team believes provided space for air sacs in the dinosaur's body.
"These spaces are unusually large in this species," Dodson said. "It's believed that dinosaurs, like birds, had air sacs in their trunk, abdominal cavity and neck as a way of lightening the body."
In addition, the longest tooth they found was nearly 15 centimeters long. Another shorter tooth contained unique characteristics, including two "buttresses," or bony ridges, on the internal side, while Euhelopus had only one buttress on its teeth.
To gain a sense of where Yongjinglong sits on the family tree of sauropods, the researchers were able to compare its characteristics with specimens from elsewhere in China, as well as from Africa, South America and the U.S.
"We used standard paleontological techniques to compare it with phylogenies based on other specimens," Dodson said. "It is definitely much more derived than Euhelopus and shows close similarities to derived species from South America."
Not only does the discovery point to the fact that Titanosaurs encompass a diverse group of dinosaurs, but it also supports the growing consensus that sauropods were a dominant group in the Early Cretaceous -- a view that U.S. specimens alone could not confirm.
"Based on U.S. fossils, it was once thought that sauropods dominated herbivorous dinosaur fauna during the Jurassic but became almost extinct during the Cretaceous," Dodson said. "We now realize that, in other parts of the world, particularly in South America and Asia, sauropod dinosaurs continued to flourish in the Cretaceous, so the thought that they were minor components is no longer a tenable view."

Blood and lymphatic capillaries grown for the first time in the lab

Researchers at the University Children's Hospital Zurich and the University of Zurich have engineered skin cells for the very first time containing blood and lymphatic capillaries. They succeeded in isolating all the necessary types of skin cells from human skin tissue and engineering a skin graft that is similar to full-thickness skin.
Every year around 11 million people suffer severe burns. The resulting large, deep wounds caused by burning only heal slowly; this results in lifelong scars. What is needed to reduce this kind of scarring is the grafting of functional full-thickness skin. Only a very limited area of skin can be removed from the individual patient as the surgery, in turn, creates new wounds. Besides conventional skin grafting, another option is to engineer a skin graft in the lab which firstly is composed of the patient's cells and secondly is very similar to natural human skin.
Up to now these complex skin grafts didn't contain any blood or lymphatic capillaries, pigmentation, sebaceous glands, hair follicles or nerves. The researchers at the Tissue Biology Research Unit, the research department of the Surgical Clinic and at the Research Centre for Children at the University Children's Hospital Zurich have been engineering dermo-epidermal skin grafts for some time but now they have succeeded in constructing a more complex organ. "We were able to isolate all the necessary skin cells from a human skin sample and to engineer a skin graft similar to full-thickness skin that contains for the first time blood and lymphatic capillaries too," says Martin Meuli, Head of the Surgical Clinic at the University Children's Hospital Zurich.
Fully functional lymphatic capillaries generated for the first time
Tissue fluid is excreted from a wound which accumulates in a cavity on the skin's surface and can impede wound healing. Lymphatic vessels drain off this fluid. The researchers isolated lymphatic capillary cells from the human dermis. Together with the blood capillaries that were also engineered, this guarantees rapid, efficient vesicular supply of the skin graft. Up to now, this had been a major unsolved problem in molecular tissue biology and regenerative medicine.
The scientists in the team of Ernst Reichmann, Head of the Tissue Biology Research Unit, were surprised by three findings. The individual lymphatic cells spontaneously arranged themselves into lymphatic capillaries with all the characteristics of lymphatic vessels. In preclinical trials both the human lymphatic capillaries and the blood capillaries engineered in the laboratory connected with those of the laboratory animals. "What's novel is that the lymphatic capillaries collected and transported tissue fluid; hence they were functional," explains Ernst Reichmann and goes on to add, "We assume that skin grafts with lymphatic and blood capillaries will, in future, both prevent the accumulation of tissue fluid and ensure rapid blood supply of the graft." This could markedly improve the healing process and the typical organ structure of this type of skin graft.
The first clinical application of these complex skin grafts is scheduled for 2014. They will not, however, contain any blood or lymphatic capillaries as approval has still to be obtained.

Disappearing snow increases risk of collapsing ice shelves in Antarctica

A number of floating ice shelves in Antarctica are at risk of disappearing entirely in the next 200 years, as global warming reduces their snow cover. Their collapse would enhance the discharge of ice into the oceans and increase the rate at which sea-level rises. A rapid reduction of greenhouse gas emissions could save a number of these ice shelves, researchers at Utrecht University and the British Antarctic Survey say in a new paper published today in the Journal of Glaciology.
Back in 1995 and 2002, two floating ice shelves in the north of the Antarctic Peninsula (Larsen A and B) suddenly collapsed -- each event occurred in a matter of weeks.
Dr Peter Kuipers Munneke, the paper's lead author, said: "This was a spectacular event, especially when you imagine the size of these ice shelves, which are several hundreds of metres thick, and have been in place for over 10,000 years."
The team of researchers suspected that the disappearance of the snow layer on top of the ice shelves could be an important precursor for shelf collapse. Their calculations confirm this hypothesis, and show that many more ice shelves could disappear in the next 200 years.
The scientists believed the snow layer plays an important role in regulating the effect of meltwater lakes on the ice shelves.
As long as the snow layer is sufficiently thick and cold, all meltwater can sink into the snow and refreeze. But in a warmer climate, the amount of meltwater increases, and the snow layers become thinner.
As a result, meltwater can no longer refreeze and forms large lakes on the surface of the ice shelves. The water drains through cracks and faults, causing them to widen until they become so wide and deep that the entire ice shelf disintegrates.
After their collapse, ice shelves can no longer provide resistance to the flow of the glaciers previously feeding them. As a result, the glacier flow accelerates significantly, contributing to an increase in sea-level rise.
The researchers performed calculations that show how this process may evolve over the next 200 years, using two different climate scenarios.
Dr Kuipers Munnekke said: "If we continue to burn fossil fuels at the current rate, almost all ice shelves in the Antarctic Peninsula will be under threat of collapse in the next 200 years. Only the two largest ones seem to be safe. Even in the much colder eastern part of Antarctica, some ice shelves could disintegrate. If we manage to keep global warming below the European Union target of 2oC, more than half of the ice shelves could be saved, compared to no action taken on emissions reductions."
The study received financial support from the European Union's four-year ice2sea project. Prof. David Vaughan said "We've been observing ice-shelf retreat around the Antarctic Peninsula since the early 1990s, but for the first time this model provides a strong basis for the prediction of future changes, which is a major step forward in understanding future sea-level changes."

本季度包括合资企业的运营收入为91亿瑞典克朗，环比增长115%。2013年全年包括合资公司，共实现运营收入178亿瑞典克朗，而2012年全年这个数字为105亿瑞典克朗。本季度包括合资企业的运营利润率为13.5%，而去年同期为负5.7%。2013年全年这个数字为7.8%，而2012年全年为4.6%。2013年第四季度实现净收入为64亿瑞典克朗，而2012年同期则为负63亿瑞典克朗。2013年全年实现净收入122亿瑞典克朗，而2012年全年这个数字则为59亿瑞典克朗，同比增长105%。
截止2013年底，爱立信持有净现金378亿瑞典克朗，而2012年底时爱立信持有的净现金则为385亿瑞典克朗。
爱立信总裁兼首席执行官卫翰思(Hans Vestberg)表示："2013年，考虑汇率因素， 按可比单位计算，爱立信年销售同比增长5%。我也很高兴地看到，我们已成功地与三星达成知识产权交叉许可协议。 我们所处的行业建立在规模化基础之上，一贯秉承公平、合理、非歧视(FRAND)的原则，通过许可来共享技术。这一协议的达成，表明了我们研发投资的价值，使得我们两家公司能够不断坚持创新、将新技术推向市场。"
我们对盈利能力的关注已开始得到回报。 尽管受到汇率下降的巨大挑战，但得益于网络销售和网络部署的积极驱动，集团运营利润率在2013年逐渐好转。
公司业务组合中网络覆盖项目多于扩容项目的状况，在2013年呈逆转趋势，往更多的扩容项目上发展。正如我们预料的那样，第四季度销售遭遇到一些压力。我们也在此前的报告中沟通过， 销售压力主要来自两个大型移动宽带覆盖项目的变化，一是北美项目在2013年上半年见顶，以及日本项目的活跃度下降。
通过在美国完成的多个大型部署项目，我们进一步加强了我们的专业服务地位和实力。从全年来看，全球服务业务占公司北美地区销售的很大一部分。美国是世界上最先进、同时也具有活力的信息通信技术市场之一，而现在，无论从电信服务的角度，还是移动基础设施的角度，我们都已成为这一市场的领导者。
中国的LTE招标仍在继续进行。到目前为止，两家已完成设备供应商招标的主要运营商均已选择了爱立信。在第四季度，受到中国的移动宽带覆盖项目交付的积极影响，中国市场的销售额得到改善。
第四季度，爱立信在欧洲主要市场的增长得以持续。过去几年内，通过网络现代化项目，我们加强了在欧洲的市场地位。这些项目按计划已完成交付，因此，它们曾经对公司利润率产生的负面影响已成为过去式。随着时间的推移，我们预计，受欧洲宏观经济发展影响，以及欧洲一家大型运营商近期宣布的通信投资的驱动，欧洲的电信业将会得到提振。
2013年，爱立信展开了多项战略性举措，包括管理行业中正在发生的技术转移与针对未来业务机会进行的公司转型。我们在继续巩固核心业务的基础上，采取了一些重要举措，旨在新的和有针对性的关键领域树立行业领先地位，具体包括巩固Modems业务、收购微软Mediaroom的IPTV业务等。我们还将逐步提高在上述领域以及在知识产权、云、运营支撑解决方案/业务支撑解决方案(OSS/BSS)的资源和资金分配力度。
信息通信行业长远发展的基础依旧坚实而令人瞩目，我们将凭借我们正在进行中的各项战略举措，在不断变革的信息通信市场中，持续支持我们的客户。
卫翰思最后补充道："我们一直在努力改善营运资本。2013年底，公司的现金流强劲，达到174亿瑞典克朗，全年的现金转换达到79%，超出之前所定下的70%的目标，这给爱立信提供了坚实的资产负债基础，来继续执行公司的战略。公司董事会建议2013年每股分红3.00瑞典克朗，比去年增长9%。"

路透北京1月30日 -中国联想集团的首席财务官黄伟明称，为收购谷歌旗下摩托罗拉移动，公司没有在债市融资的紧迫需求。
黄伟明还在媒体简布会上称，去年公司手握30亿美元资金，而收购摩托罗拉移动和IBM低端服务器的资本支出总计约为28亿美元。
联想集团周三表示，同意以29.1亿美元买下谷歌旗下的摩托罗拉手机业务，这是中国企业在科技领域的最大一笔收购交易。联想通过这种方式，杀入竞争白热化的美国手机市场，目前苹果在该市场占有优势。(完)

前NSA合同工Edward Snowden将有机会获得2014年度的诺贝尔和平奖。两名挪威议会议员Baard Vegard Solhjell和Snorre Valen向诺贝尔和平奖评选委员会提名Snowden为诺贝尔和平奖候选人，理由是他曝光了NSA监控全世界的秘密，激发了有关政府信任的公众辩论，而政府信任是和平的必要条件。现任美国总统奥巴马在上任第一年获得了诺贝尔和平奖，而被白宫官员称为美国叛徒的Snowden倒像是比奥巴马更有资格成为和平奖得主。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.

除夕微米再升级 借"活动"让社交走向线下

1月30日大年三十，新浪旗下移动群组社交产品微米通过Appstore正式发布了1.9版，上线了许多新功能，譬如神秘的群联盟、好玩的语音密语，尤为值得关注的是所有群组中都出现了一个新的页面——"活动"。业内分析人士认为，这是微米将社交从线上延展到线下，希望更进一步促进用户关系沉淀的重要标识。
新版欢迎页昭示新功能
"群活动"：让群组社交走向线下
众所周知，微博能够帮你快速了解到名人最新动态和世界各个角落里发生的新闻大事，但你更多的只是个旁观者。微信能够帮助你和朋友联系的更紧密，但对你并没有拓展价值，你从未走出自己的圈子。而由新浪微博推出的移动群组社交产品微米，恰恰扮演了帮你从自己的小圈子走向大圈子的角色。
线下活动随时向群成员发起
在新版微米群组中，原本使用率较低的"简介"被替换为"活动"。整体界面比较简洁，便于发布。群主和管理员有权限随时发起活动，并可以在群中置顶，群内成员看到后可自由选择是否参加。群活动功能的推出让用户可以通过手机便捷的查看、参与并通过微博微信分享群内活动，邀请好友一同参加，这就有助于群内成员之间的熟悉和关系沉淀，让原本陌生的网友逐渐变成熟悉的好朋友，这也恰恰是微信所做不到的。
群活动分享途径广泛
据介绍，由于安卓版本发布在先，所以微米各个分类里的热门群组基本上都已经推出了各自的群组活动，对群组成员活跃度提升效果明显。
语音密语 表白神器还是偷情神器？
除了群活动，新版微米还将密语功能进行了强化，除了在图片密语的基础上增加了涂鸦功能，还推出了全新的语音密语，在新的欢迎页里更是直接的喊出"表白神器"的口号。
据了解，语音密语支持录制60秒内的声音发送给好友或者群组，在群组里发布还可以通过"不让他听"去屏蔽那些不希望听到的人。很明显，相比图片密语，语音密语更安全，无论你在里面说了什么，别人听完就没有了，截屏没有任何意义，可以很好的避免被二次传播，保护用户的隐私。很多网友在使用之后都在群内惊呼，这哪里是表白神器，分明是和情人保持联络的偷情神器，听完自动消失毫无痕迹，完全不用担心被老婆发现。
图片密语可任意涂鸦 声音密语功能进界面简洁
除了上述功能外，新版微米的欢迎页里还展示了一个名为"群联盟"的产品功能，但在具体的产品里并未有群联盟的明显入口和呈现。据微米团队介绍，这是一个解决大群组沟通问题的产品功能，目前还在小范围邀请测试中，待完全成熟后才会正式对外开放申请。

沈阳：大量群发短信及内容涉黄赌毒手机可被锁
http://go.rss.sina.com.cn/redirect.php?url=http://tech.sina.com.cn/t/2014-01-30/17469138245.shtml
Jan 30th 2014, 09:46
春节马上就来，您会选择哪种方式传达祝福？尽管微博拜年、微信拜年风生水起，但短信拜年仍是沈阳人拜年的主要方式。1月29日，沈阳晚报、沈阳网记者从沈阳地区联通、电信、移动三大运营商了解到，为遏制垃圾短信，沈阳部分运营商早已执行短信"限发令"，一旦一小时内发送短信息超过200条，手机短信功能将被"上锁"。
群发短信过多可能被限
近年来，群发拜年短信成为不少沈阳市民过年的常规动作，不过去年有的市民自己群发短信后，会突然发现短信再也发不出去了，这是咋回事？
辽宁电信相关负责人推测，这可能是系统误认为该用户在发垃圾短信而自动限制了短信发送功能。
记者了解到，为有效治理垃圾短信，工业和信息化部要求三大电信运营商对每日发送短信数量超过一定标准的用户发送行为进行拦截处理，"短信限发令"因此而出台。
辽宁电信相关负责人表示，如果某个手机号码在某个时段内发短信到了一定数量，系统会对它的短信功能进行限制。被误会的市民可以到营业厅解除这个限制。那么，具体发多少条短信会被限制呢？辽宁电信相关负责人表示，根据规定，每号码每小时不得超过200条。
而联通方面早在2010年就下发过通知，从大年三十的8时至正月初七的0时，一旦用户每小时发送的短信数量超过400条，那么这位用户的短信功能就将被"上锁"。短信功能"上锁"后，会在72小时后重新恢复。
拜年别开"黄色"玩笑
在短信内容上，各运营商也有严格的规定。辽宁电信相关负责人透露，根据上级要求，包括涉及黄、赌、毒等敏感字眼的短信都将被无情地拦截，如果转发超过一定数量，手机甚至有可能被停机。
记者了解到，去年，沈阳就有一位手机用户，因转发5条垃圾短信导致手机被停机。
去年拜年短信摁掉近3000万元
"看春晚，放鞭炮，发短信，吃饺子"——这已成为沈阳人过除夕约定俗成的"四件套"。蛇年的除夕至初六，沈阳地区移动用户共发送短信1.97亿条，其中多为拜年短信，较前一年减少230万条，降幅1.16%，这是短信拜年方式兴起以来首次出现下降。而综合三大运营商的统计数据，去年春节期间，全市手机用户发送短信数量近3亿条，如果按照每条短信资费0.1元来计算，沈阳人短信拜年的花费接近3000万元。

春节马上就来，您会选择哪种方式传达祝福？尽管微博拜年、微信拜年风生水起，但短信拜年仍是沈阳人拜年的主要方式。1月29日，沈阳晚报、沈阳网记者从沈阳地区联通、电信、移动三大运营商了解到，为遏制垃圾短信，沈阳部分运营商早已执行短信"限发令"，一旦一小时内发送短信息超过200条，手机短信功能将被"上锁"。
群发短信过多可能被限
近年来，群发拜年短信成为不少沈阳市民过年的常规动作，不过去年有的市民自己群发短信后，会突然发现短信再也发不出去了，这是咋回事？
辽宁电信相关负责人推测，这可能是系统误认为该用户在发垃圾短信而自动限制了短信发送功能。
记者了解到，为有效治理垃圾短信，工业和信息化部要求三大电信运营商对每日发送短信数量超过一定标准的用户发送行为进行拦截处理，"短信限发令"因此而出台。
辽宁电信相关负责人表示，如果某个手机号码在某个时段内发短信到了一定数量，系统会对它的短信功能进行限制。被误会的市民可以到营业厅解除这个限制。那么，具体发多少条短信会被限制呢？辽宁电信相关负责人表示，根据规定，每号码每小时不得超过200条。
而联通方面早在2010年就下发过通知，从大年三十的8时至正月初七的0时，一旦用户每小时发送的短信数量超过400条，那么这位用户的短信功能就将被"上锁"。短信功能"上锁"后，会在72小时后重新恢复。
拜年别开"黄色"玩笑
在短信内容上，各运营商也有严格的规定。辽宁电信相关负责人透露，根据上级要求，包括涉及黄、赌、毒等敏感字眼的短信都将被无情地拦截，如果转发超过一定数量，手机甚至有可能被停机。
记者了解到，去年，沈阳就有一位手机用户，因转发5条垃圾短信导致手机被停机。
去年拜年短信摁掉近3000万元
"看春晚，放鞭炮，发短信，吃饺子"——这已成为沈阳人过除夕约定俗成的"四件套"。蛇年的除夕至初六，沈阳地区移动用户共发送短信1.97亿条，其中多为拜年短信，较前一年减少230万条，降幅1.16%，这是短信拜年方式兴起以来首次出现下降。而综合三大运营商的统计数据，去年春节期间，全市手机用户发送短信数量近3亿条，如果按照每条短信资费0.1元来计算，沈阳人短信拜年的花费接近3000万元。
