日照治疗妇科多少钱青岛药流产多少钱青岛市第八医院做人流好吗 Businesses must brace for further cyber attacks this week on a potentially “significant scale”, British intelligence officials warned yesterday, less than 48 hours after the debilitating WannaCry software virus swept across the world.毒性较大的“想哭”(WannaCry)软件病毒肆虐世界各地不到48小时之后,英国情报官员昨日警告,企业本周必须准备好对付进一步的网络攻击。Data show more than 1.3m computer systems are still vulnerable to infection by WannaCry, which paralysed hospitals, disrupted transport networks and immobilised businesses, according to cyber security analysts.据网络安全分析人士介绍,数据显示,超过130万电脑系统仍然容易被“想哭”感染,这种勒索软件已经致使医院瘫痪、扰乱了运输网络,还使企业无法运转。So far, 200,000 computers across 150 countries are known to have been infected in the first wave of the cyber attack, Europol said yesterday. “The recent attack is at an unprecedented level and will require a complex international investigation to identify the culprits,” Europe’s police agency added.欧洲刑警组织(Europol)昨日表示,迄今已有150个国家的20万台电脑在第一波网络攻击中受到感染。“最近这起袭击达到前所未有的水平,将需要展开一场复杂的国际调查来找出幕后黑手,”该组织补充称。Intelligence agencies in Europe and the US spent the weekend warning companies and organisations that the threat from the ransomware — malicious software that encrypts machines’ hard drives and demands payment to release the data — may escalate.周末期间,欧洲和美国的情报机构忙着警告企业和组织,来自勒索软件(对电脑硬盘进行加密,然后要求交钱以换取释放数据的恶意软件)的威胁可能会升级。(上图为“想哭”软件病毒的勒索信息。——编者注)“We are aware of attempts to attack other UK centres beyond the health service,” Ciaran Martin, director of the National Cyber Security Centre, an arm of the electronic intelligence agency GCHQ, told the Financial Times.“据我们掌握,有一些针对医疗部门以外的英国其他中心的攻击企图,”隶属英国电子情报机构——政府通信总部(GCHQ)的国家网络安全中心(National Cyber Security Centre)主任夏兰?马丁(Ciaran Martin)告诉英国《金融时报》。He said although the agency had warned British organisations there were likely to be further attacks today, there was no evidence WannaCry had been updated by its creators to address the element in its coding that halted its sp late on Friday. Officials still believe WannaCry is the creation of a criminal group.他说,尽管该机构已警告英国境内的组织:今日可能会发生进一步攻击,但尚未有据明,“想哭”的作者已更新其代码,以解决导致其在上周五停止传播的编码问题。官员们仍然相信,“想哭”是一个犯罪集团的产物。“With the National Crime Agency we have an around-the-clock effort to work out who is responsible,” Mr Martin said. “We have a number of leads but we can’t comment on them.”“我们正与国家打击犯罪局(National Crime Agency)合作,全天候追查罪魁祸首,”马丁表示。“我们有一些线索,但现在不能置评。”Anthony Ferrante, a former director for Cyber Incident Response at the US National Security Council, said: “We could see activity on Monday morning when people show up for work.”美国国家安全委员会(National Security Council)网络事件响应(Cyber Incident Response)前主任安东尼?费兰特(Anthony Ferrante)表示:“周一上午,当人们上班后,我们可能会看到一些活动。”Mr Ferrante, now managing director at FTI Consulting’s forensics and litigation unit, said the US government was taking the threat “extremely seriously”.如今担任富事高咨询(FTI Consulting)司法鉴定和诉讼部门董事总经理的费兰特表示,美国政府“非常重视”这一威胁。The list of organisations hit by WannaCry has lengthened in the past 48 hours: alongside Britain’s National Health Service, which saw more than a third of hospitals and clinics incapacitated, victims include German rail operator Deutsche Bahn, US logistics group FedEx, Russia’s interior ministry, French carmaker Renault, Spanish telecoms group Telefónica and state-owned China National Petroleum Corp.“想哭”袭击的组织名单在过去48小时变得更长:除了英国国家医疗务体系(NHS)三分之一以上的医院和诊所陷于瘫痪,受害者还包括德国铁路(Deutsche Bahn)、美国物流集团联邦快递(FedEx)、俄罗斯内务部、法国汽车制造商雷诺(Renault)、西班牙电信(Telefónica)以及国有的中国石油天然气集团公司(CNPC)。Despite urgent appeals from security authorities for organisations to address the critical Windows security vulnerability exploited by WannaCry, many still have not done so. “We must change our approach,” said Julian King, EU security commissioner. “We all need to take responsibility for cyber security.”尽管安全部门紧急呼吁各组织堵上“想哭”利用的Windows严重安全漏洞,但仍有许多组织没有这样做。“我们必须改变我们的做法,”欧盟安全专员朱利安?金(Julian King)表示,“我们都需要对网络安全负责。” /201705/509185日照人民医院电话多少

即墨市妇女儿童医院预约B News –Scientists think they have found a smart way to constrain carbon dioxide emissions - just turn them to stone. The researchers report an experiment in Iceland where they have pumped CO2 and water underground into volcanic rock. Reactions with the minerals in the deep basalts convert the carbon dioxide to a stable, immobile chalky solid.B新闻 – 科学家认为,他们发现了一种遏制二氧化碳排放的聪明方法 – 把它们变成石头。研究人员报告了在冰岛做的一次实验,他们把二氧化碳和地下水泵入火山岩。与地下深处玄武岩中的矿物质发生的反应,把二氧化碳转化成了稳定不动的白垩状固体。Even more encouraging, the team writes in Science magazine, is the speed at which this process occurs: on the order of months. ;Of our 220 tonnes of injected CO2, 95% was converted to limestone in less than two years,; said lead author Juerg Matter from Southampton University, UK.该团队在《科学》杂志发表报告说,更鼓舞人心的是这个过程发生的速度:大约几个月。“我们注入的220吨二氧化碳中,95%不到两年就转化成了石灰岩。”报告的主要作者,来自英国南安普顿大学的马特说。With carbon dioxide concentrations in the atmosphere marching ever upwards and warming the planet, researchers are keen to investigate so called ;carbon capture and storage; (CCS) solutions.随着大气中的二氧化碳浓度持续上升,令地球升温,研究人员热衷于探讨所谓的“碳捕捉与封存”(CCS)解决方案。Previous experiments have seen pure CO2 injected into sandstone, or deep, salty aquifers. Chosen sites - which have included disused oil and gas wells - have relied on layers of impermeable capping rocks to hold down the carbon dioxide. But the fear is always that the CO2 could find a way to leak back out into the atmosphere.此前的实验是把纯二氧化碳注入砂岩,或深部咸水层。废弃的油井和气井等中选场地依靠不透水的盖层岩石地层压缩二氧化碳。但一直令人担心的是,二氧化碳可能夺路而出,回漏到大气中。Working with a geothermal power plant, the Carbfix project on Iceland combined the waste CO2 with water to make a slightly acidic liquid that was then sent hundreds of metres down into the volcanic basalts that make up so much of the North Atlantic island.在冰岛进行的这个固碳项目与一座地热电站合作,把二氧化碳废气与水结合,制成弱酸性液体,然后输送到地下几百米的火山玄武岩 - 这些岩石在这座北大西洋岛国是如此丰富。The low pH water (3.2) worked to dissolve the calcium and magnesium ions in the basalts, which then reacted with the carbon dioxide to make calcium and magnesium carbonates. Cores drilled into the experimental site pulled up rock with the tell-tale white carbonates occupying the pore spaces.PH值3.2的酸性水分解玄武岩中的钙镁离子,然后与二氧化碳发生反应,产生碳酸钙和碳酸镁。从实验地点钻探岩心取出岩石,明显可见白色的碳酸盐占据了孔隙空间。The researchers also tagged the CO2 with carbon-14, a radioactive form of the element. In this way, they were able to tell if any of the injected CO2 was leaking back to the surface or finding its way out through a distant watercourse. No such escape was detected.研究人员还用碳元素的放射性形式碳14标记二氧化碳。用这种方法,他们能够断定注入的二氧化碳是否回漏到表层,或通过长距离水道找到了出路。但并未探测到这种逃逸。;This means that we can pump down large amounts of CO2 and store it in a very safe way over a very short period of time,; said study co-author Martin Stute from Columbia University#39;s Lamont-Doherty Earth Observatory, US.“这意味着我们可在非常短的时间内把大量二氧化碳泵入地下,用非常安全的方式封存它。”研究报告的共同作者,来自美国哥伦比亚大学拉蒙.多哈提地球观测站的司徒特说。 /201606/449459 1. Biotech1.生物科技Since the early 2000s, the cost of sequencing a human genome — determining the precise order of nucleotides within DNA molecules that defines who we are — has dropped sharply. A genome that cost 0m to sequence in 2001 can today be sequenced for roughly ,000.自本世纪初以来,人类基因测序(确定DNA分子内部核苷酸的确切排序,这一排序决定了我们是谁)的价格已大幅下跌。2001年基因测序的价格高达1亿美元,如今仅为1000美元左右。This plummeting cost, along with the shortened timescales for sequencing DNA, has led to a revolution in biotechnology: gene hacking, or the ability to turn genes on and off, and to manipulate biology to our advantage.价格下跌再加上DNA测序所需时间缩短,带来了生物技术领域的革命:基因黑客技术,能够开启和关闭基因、操纵生物学让其为我们所用。The most radical branch of this new technology is “gene editing” — a process by which our DNA code can be cut and pasted using molecular “scissors” for a variety of applications, including curing diseases such as cancers and HIV. Until recently, swapping the code was an arduous process. A new DNA cut-and-paste tool known as Crispr has made the process unexpectedly simple.这种新技术的最激进分是“基因编辑”:利用分子“剪刀”剪切和粘贴我们的DNA编码的过程,其用途很多,包括治愈癌症和艾滋病等疾病。直到不久前,DNA编码交换曾是一个困难的过程。名为Crispr的新的基因剪切与粘贴工具让这个过程变得意外地简单。Crispr has been used to create disease-resistant strains of wheat and rice, alter yeast to make biofuels and reverse blindness in animals. Ultimately, it could be used to edit defects out of human embryos.Crispr用来创造抗病的小麦和大米品种、改变酵母菌以制造生物燃料并治疗动物失明。最终,它或许可用于消除人类胚胎中的缺陷。2. Artificial intelligence2.人工智能Artificial intelligence is not science fiction: it is aly embedded in products we use every day. Apple’s Siri assistant, Amazon’s book recommendations, Facebook’s news feed and Spotify’s music discovery playlist are all examples of services driven by machine learning algorithms.人工智能并非科幻小说:它已经嵌入到我们每天使用的产品中。苹果(Apple)的Siri助理、亚马逊(Amazon)的图书推荐、Facebook的新闻推送以及Spotify的音乐发现列表都是由机器学习算法驱动的务的例子。This decades-old science is enjoying a renaissance today because of the deluge of data created by smartphones and sensors, and the supercomputing power that is available to crunch that data. According to technology research firm Tractica, the AI market will grow from 3.7m in 2016 to .8bn by 2025.这门拥有几十年历史的科学如今正经历复兴,因为智能手机和传感器创造了大量数据,并且如今我们有了能够处理这些数据的超级运算能力。根据科技研究机构Tractica的数据,人工智能市场的规模将从2016年的6.437亿美元扩大到2025年的368亿美元。Techniques such as deep learning and neural networks supposedly mimic the human brain: they spot broad patterns in enormous data sets in order to label images, recognise voices and make decisions.据说,深度学习和神经网络等技术会模仿人脑:它们会识别大量数据集中各种大的模式,以实现对图片的归类、识别声音和做出决定。The next step is artificial general intelligence: an algorithm that will not have to be taught a specific skill such as a game of chess or a new language, but will acquire it through trial and error, just as a child does. Companies such as London-based DeepMind, owned by Google, and others are working to make this a reality.下一步是通用型人工智能:这种算法不需要被教授具体技能(例如下棋或一门新的语言),而是会通过试错法来习得技能,就像儿童所做的那样。总部位于伦敦的DeepMind(由谷歌(Google)所有)等公司以及其他公司正致力于让这变为现实。3. Renewable energy3.可再生能源World leaders last year ratified the Paris Agreement on climate change.世界各国领导人去年批准了《巴黎气候协议》(Paris Agreement)。This aims to keep the global average temperature from rising more than 2C above pre-industrial levels and to attempt to keep the increase under 1.5C. Keeping this promise will require more renewable energy research over the next decade.该协议旨在阻止全球平均气温较工业时代以前的水平升高2摄氏度以上,并试图将升温幅度控制在1.5摄氏度以下。兑现这一承诺将需要在未来10年加大可再生能源研究。In energy, researchers are trying to build a nuclear fusion reactor that would tap the same process that causes the sun to give off light and heat to create a source of clean energy. An intergovernmental partnership is building a bn fusion reactor, ITER, in France. Other innovations include artificial photosynthesis to make hydrocarbons in laboratories to power cars, and high-altitude wind power that involves kites and hot-air balloons acting as aerial wind turbines.在能源领域,研究人员正试图建造一个核聚变反应堆,利用与太阳发光发热原理相同的过程,创造出一个清洁能源来源。一项政府间合作计划正在法国建造一个190亿美元的核聚变反应堆ITER。其他创新计划包括:人工光合作用,在实验室中制造碳氢化合物为汽车提供动力;高海拔风电厂,把风筝和热气球作为空中风力涡轮。Iceland is investing in geothermal technology, drilling for heat energy underground. Thirty years ago it started by using geothermal resources to heat towns and cities. Now, the entire country’s electricity and heating systems are powered almost fully by renewable energy, including geothermal and hydropower.冰岛正在投资发展地热技术,通过钻探开采地下热能。30年前,该国开始利用地热资源为城镇供暖。如今,整个国家的电力和供暖系统几乎全部依靠可再生能源,包括地热和水电。4. Connectivity4.网络接入技术WiFi — a household staple that modern children take for granted — turned 25 last September. As more objects connect to the “internet of things” — an estimated 50bn of them by 2020, according to estimates from technology company Cisco — the future of WiFi lies in reducing the power it drains from internet-enabled devices.WiFi是现代儿童眼中理所当然的家庭标配,去年9月,这项技术度过了25岁生日。随着更多设备与“物联网”相连(根据科技公司思科(Cisco)的估计,到2020年,联入物联网的设备将达到500亿台),WiFi的未来取决于降低其在联网设备上消耗的电量。One innovation, invented by students at the University of Washington in Seattle, is known as “passive WiFi” which its inventors say consumes 10,000 times less power. It is currently slower than regular home broadband, but would work well for applications such as smart thermostats or lightbulbs. The WiFi community is also looking to develop higher-frequency bands that would be used over a limited range, such as in a house or car.位于西雅图的华盛顿大学(University of Washington)的学生发明了一种创新技术,名为“被动WiFi”。发明人称,耗电量仅为以前的万分之一。目前速率低于一般的家庭宽带,但应用于恒温器或灯泡等设备效果很好。WiFi界还计划开发更高的频段,用于覆盖有限的范围,例如家中或车里。Ultimately, WiFi itself could be replaced by a new superfast alternative called Li-Fi, which uses light to beam information through the air, instead of radio waves. Lightbulbs would act as routers for this technology. A pilot study earlier this year found that a Li-Fi prototype could send data 100 times faster than WiFi, allowing dozens of movies to be downloaded in minutes.最终,WiFi可能会被另一种新的超高速连接技术Li-Fi取代,这种技术利用光通过空气(而非无线电波)传输信息。灯泡将作为这项技术的路由器。今年早些时候的一项试验研究发现,Li-Fi样机的数据传输速度是WiFi的100倍,几十部电影可以在几分钟之内下载完毕。5. Smart appliances5.智能家电Almost two-thirds of the human population is connected to the internet via smartphones, but these devices are not the only portal to the web. In 2016 there were 6.4bn connected things — excluding PCs, phones and tablets — in use worldwide, up 30 per cent from the previous year, according to technology analyst Gartner. The internet of things, as it is known, is this universe of objects — everything from cars to printers, lightbulbs to thermostats — that are no longer “dumb”, static things: they can learn your habits and be controlled remotely using an app.全球近三分之二的人口通过智能手机连接互联网,但智能手机并非唯一的互联网接入门户。技术分析机构高德纳(Gartner)的数据显示,2016年,全球有64亿个使用中的联网设备(不包括个人电脑、手机和笔记本电脑),较上一年高出30%。物联网正是这些联网设备的集合,从汽车到打印机、灯泡到恒温器,它们不再是“愚笨”、静止的物体:它们可以学习你的习惯并通过应用远程控制。The stereotypical smart appliance is the self-stocking refrigerator that replenishes your milk automatically. This innovation will replace a lot more than the sniff test. Cars are now computers, running more lines of code than the Apollo 11 spaceship on its way to the moon. As these computers become more intelligent, cars will drive themselves, potentially reducing traffic-related fatalities. Smart sensors can also transform industry, for instance by monitoring goods during transport, helping utility companies to measure energy usage and logistics companies to track vehicles over long distances.典型的智能家电是可以自动备货的冰箱,能够自动补充牛奶。这种创新带来的方便远不止是不再需要靠嗅觉来判定食品是否变质。汽车现在变成了电脑,运行的代码行数比阿波罗11号(Apollo 11)宇宙飞船飞往月球时还要多。随着这些电脑变得更为智能,汽车将实现自动驾驶,可能会减少交通事故导致的死亡。智能传感器还能彻底改造业态,例如,通过监测运输过程中的商品,帮助公用事业企业衡量能耗以及帮助物流公司远程追踪车辆。 /201703/498494青岛那家医院做无痛人流最好青岛专业妇科医院在线咨询
