阿坝州市纹绣美甲美睫批发商城市场学校机构眉山市高级形象设计彩妆化妆学习培训学校排行榜German scientists have created a three-dimensional ;invisibility cloak; that can hide objects by bending light waves.德国科学家近日研制出一种通过弯曲光线来隐藏物体的三维“隐形斗篷”。The findings, published in the journal Science on Thursday, could in the future make it possible to make large objects invisible, but for now the researchers said they were not keen to speculate on possible applications.这项发明为大型物体隐形铺平了道路,但研究人员称,目前他们并不想去猜测可能的应用形式。这一最新研究成果于上周四在《科学》期刊上发表。For now these...cloaking devices are just a beautiful and exciting benchmark to show what transformation optics can do, said Tolga Ergin of the Karlsruhe Institute of Technology.德国卡尔斯鲁厄理工学院的研究人员托尔加·埃尔金说:“目前,这种隐形斗篷只是光学领域一个‘惊艳’的开始,让人们知道转换光学可以做些什么。”Transformation optics use a class of materials called metamaterials that guide and control light.转换光学通常使用一种“超材料”来引导和控制光束。In their study, Ergin and his colleagues used photonic crystals with a structure that looks like piles of wood to make an invisibility device, or cloak.埃尔金及其同事在研究中使用了一种光子晶体来制造隐形斗篷。这种光子晶体的结构看上去像成堆的木头。They used the cloak to conceal a small bump on a gold surface -- a bit like hiding a small object underneath a carpet and then making both the bump and the carpet invisible.研究人员使用隐形斗篷来掩盖黄金表面的一个小凸起,其原理就如同将一个小物体隐藏在地毯下,然后再使这个凸起和地毯都隐形。The ;cloak; was composed of special lenses that work by partially bending light waves to suppress the light scattering from the bump.这个“斗篷”由特殊透镜组成,它通过部分弯曲可见光线来抑制凸起发出的光。This is very exciting, because mankind has always thought about being invisible or having invisibility cloaks, Ergin told the reporters in a telephone interview. ;This is the first proof of principle. It shows that the technique works.;埃尔金在接受一个电话采访时说:“这一发明十分令人激动,因为人类一直都想隐形或拥有隐形斗篷。这是我们的首个隐形样本,看来这一技术是可行的。”He added, however, that it would be many years before anything as large as a person, car or tank could be made to disappear with this technique.但他认为,利用上述技术使人、汽车、坦克等大型物体隐形尚需时日。There have been proposals in the field of transformation optics for different devices like beam concentrators, beam shifters, super antennas which concentrate light into one point from all directions, and much, much more, he said.他说:“转换光学领域曾出现过各种有关光学设备的提议,如波束集中器、波束移位器以及可将来自多个方向的光集中于一点的超级天线等等。”It is really hard to say what the future will bring, but the field is definitely very broad and the possibilities are very large.“很难说将来还会有什么发明,但转换光学绝对是个范围广、充满无限可能的领域。” /201507/389035乐山美甲2016款式时尚结婚美甲图片培训班 I’m sitting in Sumon Pal’s office in Boston’s Back Bay, and while fixing two small electrodes to my head with a light adhesive—one to my temple, another to the back of my neck—he’s explaining what the next 16 minutes should feel like. Most users feel reduced tension in their bodies, he says. Their thoughts ping-pong less frequently, breathing slows noticeably, and thoughts that typically cue anxiety—of work, of relationships, of family—become less consequential.我正坐在萨门o帕尔位于波士顿后湾区的办公室里,他一边用轻型粘合剂在我的头上安装小型电极——一个粘在太阳穴上,另外一个在脖子后面,一边解释接下来16分钟的感受。他表示,大多数使用者会感觉身体里的紧张感减轻。他们的思维跳跃频率降低,呼吸明显放缓,与工作、人际关系或家庭有关的那些通常引发焦虑感的想法,也随之减少。Pal, executive director of Los Gatos, Calif., -based neuroscience startup Thync, designed the calming “vibe” that’s being imparted to my brain through a prototype of the app-controlled wearable device that the company will release later this year. Thync’s technology utilizes tDCS, or transcranial direct current stimulation, to trigger specific responses in the brain, dialing up feelings of calm and serenity or conjuring energy and focus on demand.帕尔是加州洛斯盖多斯神经科学初创公司Thync的首席执行官,他设计出这种令人平静的“氛围”,并且通过一款由应用控制的可穿戴设备原型将这种氛围传递到我的大脑当中。该公司预计将在今年晚些时候发布这款设备。Thync的技术利用经颅直流电刺激(tDCS)来触发大脑的某些反应,产生平静的感觉,或根据需要激发出能量和专注。Thync isn’t out to alter the brain’s biology, but to allow better control of the energy, focus, and calm that are aly naturally available to us, co-founder and chief science officer Jamie Tyler says. “Coffee, alcohol, drugs; these are all neuro-enhancers,” Tyler says. “You’re aly modifying your brain activity.” Thync wants to better harness that command—and perhaps grab a piece of the alcohol, coffee, pharmaceutical, and energy drink markets collectively worth billions.公司联合创始人兼首席科学官贾米o泰勒表示,Thync的目的并非改变大脑的生物活动,而是让我们更好地控制我们生来便可以使用的能量、专注和平静。泰勒说道:“咖啡、酒精、药物,这些都属于神经增强剂。你已经在改变大脑的活动。”Thync希望更好地利用这种能力,这样或许就可以从价值数十亿美元的酒精、咖啡、药物和能量饮品市场中分得一杯羹。The pulses—each “100 times lower than what’s considered dangerous,” Tyler insists—feel comfortably warm but not painful. Just as Pal described, the familiar tension in my shoulders eases, my breathing slows, my mind noticeably stops racing. My body takes on the feeling of lax warmth usually associated with a finger or two of scotch—my usual means of unwinding.泰勒坚持认为,设备产生的脉冲让人感觉温暖舒适,不会有疼痛感,其强度仅有危险脉冲的百分之一。正如帕尔所描述的那样,我肩部那种熟悉的紧张感消失了,呼吸放缓,大脑开始陷入平静。我的身体感觉到令人放松的温暖,我通常在吸一两口苏格兰鼻烟之后才会有这种感觉——这也是我常用的放松方式。“People have been doing this forever, this is nothing new,” Tyler says. “I think this is the kind of product people have been waiting for.”泰勒说道:“人类一直都在这么做,这没什么新鲜。我认为这是那种人们一直在期待的产品。”(财富中文网) /201502/359898Synthesized Crystalline Bovine Insulin第一个人工合成牛胰岛素Synthetic bovine insulin, which was fully developed in 1965 following 6 years of hard work by a group of Chinese scientists, was the first case of human beings synthesizing live proteins. This is the first time that zoetic protein has been synthesized by human in history. In the past it was a universal belief that man could by no means synthesize living body. The success made it possible for Chinese scientists to deflate the traditional concept. Synthetic bovine insulin marked a significant breakthrough in the fIeld of life science and has substantially influenced human endeavors in finding out the secrets of life.1965年,我国的科学工作者经过6年多坚持不懈的努力,获得了人工合成的牛胰岛素结晶。这是世界上第一个人工合成的蛋白质。过去世界普遍认为生命体是天然的,大都认为人工合成生命体是不可能的,是中国人首次让它变成可能。人工牛胰岛素的合成,是生命科学领域的重大突破,对于人类探索生命奥秘的影响是巨大的。 /201602/419388崇州市纹绣半永久加盟培训学校哪个好些

什邡纹绣美甲美发业彩妆培训中心怎么样好吗Earlier this year, Microsoft unveiled a viral tool that claimed to be able to guess your age from a single photo.今年早些时候,微软发布了一款能看照片猜年龄的工具,并疯狂传播开来。Outraged 20 year-olds took to social media when they were told they looked 40, while middle-aged men were given a boost when the software said they looked 30.20多岁的年轻人被告知看起来像40岁,气愤地诉诸社交媒体。而中年人则备受鼓舞,因为软件说他们看起来像30岁。Now, Microsoft is doing the same thing with emotions, with a new online tool that they say can reveal how a person is really feeling in their images.如今,微软正兴致勃勃地做着同样事情——发布一款能够显示图片中人真实感受的网络工具。When tested on celebrities, it found Kate Middleton was elated on her wedding day, with the Duchess of Cambridge scoring a 100 percent rating on happiness.经过对各位名人的测试,该软件发现凯特·米德尔顿在她的婚礼上非常开心,剑桥公爵夫人的开心度达到了100%。Meanwhile, Kim Kardashian#39;s #39;neutral face#39; in a photo snapped while with husband, Kanye revealed that she was around 70 percent happy.而同时,在偶然拍到的一张金·卡戴珊与老公坎耶的合影中,卡戴珊“平淡的表情”表明,她的高兴大约占70%。The remainder of her emotions range from contempt to anger and disgust.剩下的情绪则包括蔑视、愤怒和厌恶。And while Taylor Swift may appear elated, her image shows that she#39;s only around 40 percent happy.而尽管泰勒·斯威夫特看起来兴高采烈。照片表明,她的开心只占40%。According to Microsoft, when accepting the Video of the Year award for #39;Bad Blood#39;, the singer was also 10 percent surprised.根据微软的信息,在因《敌对》(Bad Blood)获得年度最佳视频奖时,这位歌手的情绪中还有10%的惊讶。Republican presidential candidate Donald Trump#39;s look at Senator Marco Rubio yesterday betrayed contempt mixed a degree of happiness.昨天,共和党总统候选人唐纳德·特朗普看向参议员马可·鲁比奥的表情出卖了他。那是种蔑视混合着某种程度的开心。The software will take any photograph you upload, identify the faces, and then give each a score based on a series of different emotions.该软件能接受任何图片上传,识别面部,然后按照不同的情绪分别打分。It provides a rating for anger, contempt, disgust, fear, happiness, sadness and surprise - and anyone can test a trial version here.它可以评估愤怒、蔑视、厌恶、恐惧、快乐、悲伤和惊讶——任何人都可以用试用版进行测试。You can upload your own images of your own face, which must be at least 36 pixels square and smaller than 4MB.你可以上传自己的正面照,但图片必须至少为36正方形像素,小于4MB。To see how the software thinks you#39;re feeling, hover over the rectangle around face and you#39;ll see different emotions graded on a scale from zero to one.要获得软件对你感受的认知,请将鼠标悬停在面部周围的矩形区域内,就会出现从0~1的不同感情评分。A score of one suggests that you#39;re feeling that emotion 100 percent.1分表示目前这种情绪达到100%。Chris Bishop, head of Microsoft Research Cambridge, showed off the emotion tool earlier today in a keynote talk at Future Decoded, a Microsoft conference.在今天早些时候在微软会议Future Decoded的主题报告上,微软剑桥研究中心主任克里斯·毕修普展示了这款情绪测评软件。#39;The exciting thing has been how much interest there is and how diverse the response is,#39; said Ryan Galgon, a senior program manager within Microsoft#39;s Technology and Research group.“令人兴奋的莫过于其中的趣味性与回应的多样性,”微软技术研究部门高级项目经理赖恩·加尔贡(Ryan Galgon)说道。The software is based on machine learning, which means it gets smarter as it receives more data.这款软件基于机器学习原理,也就是说接受的数据越多,软件就越聪明。It#39;s the basis for major breakthroughs including Skype Translator#39;s real-time translation and Microsoft#39;s Cortana personal assistant.包括Skype Translator的实时翻译、微软小娜个人助手等重大技术突破都是建立在该原理之上。In the case of something like facial recognition, the system can learn to recognise certain traits from a training set of pictures it receives.在面部识别等情况下,系统能够根据此前输入的一整套训练图片识别某些情绪特征。It can then apply that information to identify facial features in new pictures it sees.随后,它便可以使用这些信息识别图片中的面部特征。Galgon said developers might want to use these tools to create systems that marketers can use to gauge people#39;s reaction to a store display, film or food.加尔贡说,研究人员希望用这些工具开发各种系统,供营销商测试人们对商品摆放、电影或食物的反应。They might also find them valuable for creating a tool, such as a messaging app, that offers up different options based on what emotion it recognises in a photo.他们可能还会用来开发应用,如消息传送app,这种应用能根据图片中识别的情绪提出不同选择。 /201511/410624遂宁学习半永久化妆术培训课程班 Apple’s car is either the worst-kept secret since its watch or a cracker of an inside joke. “Project Titan” has generated massive hype for a product that is five to 10 years off. The iCar may be electric and drive itself or not. Few know. But if it does arrive, it will be stylish, tech savvy, integrate with the iPhone and be in demand. Who will build them? Not Apple: it does not build its phones or computers, and building cars is much more complicated — just ask Tesla.苹果(Apple)汽车要么是继苹果手表之后最没能保守好的秘密,要么是个只有内行人才听得懂的高明笑话。Project Titan使一款5到10年后才有望问世的产品受到大肆炒作。iCar可能是无人驾驶的电动汽车,也可能不是。没几个人知道。但如果这款产品真正推出,它应该是一款时尚、高科技、能和iPhone整合的抢手产品。谁将是这款产品的制造者?不是苹果:苹果的手机、电脑都不是苹果制造的,而制造汽车要复杂得多——问问特斯拉(Tesla)就知道了。An existing carmaker might build it. Plenty of carmakers taught Chinese joint venture partners how to make cars as the price of admission to the growing Chinese market, even at the risk of increasing low-cost competition. The iCar market would be large and lucrative. A big global carmaker might be tempted to help with the build, even if Apple monopolised the branding, customer relationship and profitability. The benefits of scale and the brand halo might encourage them to overlook the risk of cannibalised sales.制造者可能会由一家现有的汽车制造商担当。作为获准进入不断增长的中国市场的代价,许多汽车制造商教中国合资伙伴如何制造汽车,甚至不惜冒着加剧低成本竞争的风险。iCar将拥有巨大而利润丰厚的市场。即使苹果在品牌、客户关系和盈利能力方面独占好处,或许依然会有一家大型全球汽车制造商禁不住诱惑,帮助苹果制造汽车。规模效应和品牌光环带来的好处可能会鼓励它们忽视类似产品上市的风险。More likely that a Chinese carmaker would step in. The manufacturer would be cost efficient for Apple and gain needed scale for itself. And premium-priced Apple cars are unlikely to cannibalise sales of low-priced models for the Chinese market.更有可能的是,会有一家中国汽车制造商参与进来。与这家制造商合作对苹果来说将具有成本效益,制造商自身则能获得所需的规模。定价高端的苹果汽车不大可能影响中国市场上低端车型的销售。Another likely option is Magna Steyr, the world’s largest white-label carmaker. It builds cars in European and Chinese plants to meet overflow demand or specialised, low-volume models for BMW, Mercedes-Benz, Chrysler and Aston Martin. Building cars is a side business for parent company Magna International, but the group has bn in enterprise value, supplies all the big carmakers and has been serious about growth since its founder left in late 2012 (shares are up 166 per cent since). Like the phones, most of the iCar’s profit will be Apple’s, but there is a slice of pie there for the partner.另一个可能的选项是世界最大的代工汽车制造商麦格纳斯太尔(Magna Steyr)。该公司在欧洲和中国的工厂为宝马(BMW)、梅赛德斯-奔驰(Mercedes-Benz)、克莱斯勒(Chrysler)和阿斯顿马丁(Aston Martin)制造汽车,以满足超过产能的需求,或者制造特别版的小批量车型。对于其母公司麦格纳国际(Magna International)而言,汽车制造是一项副业,但麦格纳斯太尔的企业价值达到180亿美元,是所有大型汽车制造商的供应商。该集团在其创始人2012年末离开后十分重视增长(那之后股价上涨了166%)。就像iPhone一样,iCar的大多数利润将归苹果,但合作伙伴总能从中分得一杯羹。 /201601/421002遂宁市美甲职业技能技术培训学校

攀枝花市美甲纹绣半永久学校机构Google#39;s self-driving cars have gone a total of 100,000 miles with no accidents and now the company is working towards making their vehicles even safer.谷歌的无人驾驶汽车已累计安全行驶10万英里(约16.1万公里),未发生任何事故。现在,谷歌正致力于将无人驾驶汽车打造得更加安全。The software giant recently secured a patent for technology to communicate with pedestrians.最近,该软件巨头获得了“可与行人沟通”的无人驾驶技术专利。Screens and/or a speaker system could be used to help the cars and humans coexist safely on the road.公司为这种汽车安装了屏幕和(或)扬声系统,能确保汽车和行人在道路上并行不悖。The details of the patent reveal the car will be able to sense when a person is standing in front or close to it and will then decide the next step to take.专利详情显示,行人站在汽车前方或靠近汽车时,无人驾驶汽车可感知到这种情况,并决定采取何种策略。The screens, which could be mounted on the doors or hood could flash alerts like #39;Stop#39;, #39;Safe Cross#39; or a traffic sign that would inform pedestrians about what the car is doing.此时,安装在汽车门和引擎盖上的屏幕会闪现警示信息,比如“停止”、“请安全通过”,或发出相关交通信号,示意行人它将怎样行驶。The speaker system could vocalize the text shown on the screens and send out other alerts.扬声系统可以念出屏幕上的字,或发出其他警示。The patent says, #39;the vehicle may include sensors which detect an object such as a pedestrian attempting or about to cross the roadway in front of the vehicle.#39;该专利显示:“无人驾驶汽车可能配有传感器,用于检测是否有行人意图或即将于车前横穿马路。”#39;The vehicle#39;s computer may then determine the correct way to respond to the pedestrian.#39;“无人驾驶汽车的电脑将因此采取正确的应对方式。”#39;The vehicle may then provide a notification to the pedestrian of what the vehicle is going to do or is currently doing.#39;“而后,汽车会告知行人它的行进计划或目前的行驶方向。”This past Halloween, Google was teaching cars how to recognize children in their costumes, part of a feature that is educating them how to react and act around children.刚过去的万圣节期间,谷歌对无人驾驶汽车进行了试验,让它们学会辨认儿童的身影。该计划也是无人汽车儿童适应性的一部分。And this patent takes this feature one step forward by including all pedestrians.这项新专利则让上述性能更进了一步——将所有行人都考虑在内。There is also an indication of an eye or robotic arm will be added that could notify pedestrians the car has #39;seen#39; them.该专利还显示,无人驾驶汽车可能会安装电子眼或机械手臂,知会行人汽车已经“看见”他们了。The arm could mimic that of a humans, as it #39;sweeps#39; for pedestrians to cross, but the message could come across unclear when it#39;s coming from a robot and not a real person.机械手臂可以模仿人的动作,向过马路的行人“挥手”。但由于这个动作并不是出自真人,所以很有可能让行人一头雾水。Currently, no sketches have been released of how the system would work or look, but it appears to be similar to a system Nissan showed off last month.目前为止,谷歌尚未公布该系统的运行细节或具体样子。但外界认为,该系统很有可能与尼桑上个月展出的一个相关系统类似。However, Google applied for their patent back in 2012.不过,谷歌早在2012年就申请了该专利。For Nissan#39;s futuristic vehicles, it envisions an outward-facing display in side of the windshield that tells pedestrians when the car is about to stop or if it wants someone to cross ahead of it.在尼桑的这一未来汽车构想中,挡风玻璃有朝外的显示屏,告知行人汽车将要停下,或是让前方行人先行。In the company#39;s , it shows a driver pushing a button and the steering wheel unravels then recedes back into the dashboard.尼桑的宣传视频显示,司机按下一个按钮,方向盘即解体,并缩回仪表盘内。These new vehicles can only be summoned on a smartphone from a garage to meet the driver and will greet them by name.这种新型汽车只能通过智能手机从车库召唤到司机面前,它们还会叫司机的名字,跟他们打招呼。 /201512/413711 自贡化妆造型个人生活妆造型学校机构四川纹绣美甲色料工具机器学校机构
