OnePlus’ upcoming devices – the OnePlus 7 and the OnePlus 7 Pro – are some of the most ancipated smartphones of the year. And while the two smartphones are tipped to launch on May 14, there is no official confirmation from the company yet. But that might change soon as the OnePlus chief executive officer Pete Lau has said that he would announce the date for his company’s next big launch next Tuesday, that is, April 23.”Stay tuned next Tuesday for our launch event announcement,” Lau wrote in his tweet.It is worth noting that while Lau, in his tweet, didn’t mention what the company would be launching at the event, it is safe to assume that Lau’s announcement and the event is about OnePlus’ next flagship device – the OnePlus 7.Earlier this week, the OnePlus CEO had unveiled the first official teaser of the company’s upcoming flagship device. “Excited to share the next product from OnePlus will unleash a new era of Fast and Smooth. Especially Smooth! Smooth is more challenging than Fast – a true test of hardware and software,” he had written in his tweet, which makes us believe the the upcoming OnePlus 7 and the OnePlus 7 Pro would come with 5G capabilities.Meanwhile, rumours circulating on the internet have given us plenty to speculate about. The OnePlus 7 is expected to come with a 6.4-inch display with a waterdrop notch that will house a selfie camera. On the back, the phone is expected to come with a dual camera setup with a 48MP primary shooter. It is expected to be powered with Qualcomm’s Snapdragon 855 processor and sport 8GB RAM with a 256GB storage space. On the software front, the OnePlus 7 is expected to run on the latest version of the Oxygen OS which is based on Android 9.0 Pie.advertisementAs mentioned before, OnePlus is also expected to launch the OnePlus 7 Pro alongside the OnePlus 7, which as per an Android Central report would come with a 4000mAH Battery, Quad HD+ Super AMOLED “90hz” Display, WARP Charge and a and triple camera setup. However, all these details should be taken with a pinch of salt since as OnePlus is yet to confirm these details.ALSO READ: | Latest OnePlus 7 leak reaffirms previous rumours: Full screen display, pop-up selfie camera and moreALSO READ: | OnePlus 7 will be more than just a fast and smooth user experience: Decoding the official teaserALSO READ: | OnePlus 7 Pro specs may include QHD+ display, Warp Charge and triple cameras
The freeze on this year’s class of free agents is alarming. For one thing, it took much longer than usual for a team to break the free-agent ice. And, aside from a brief acceleration during the winter meetings in mid-December, the pace of signings has been markedly slower than normal — particularly early in the offseason, when the biggest flurry of signings usually takes place.Only the 2008-09 offseason, when just 53 percent of top-40 players were signed by this stage of the winter, came close to lagging as much as the current slowdown. And even then, most of the biggest available names had already been signed by this point in the offseason. Granted, three of those (Mark Teixeira, CC Sabathia and A.J. Burnett) were all picked up by spendthrift Yankees. By contrast, the current Yankees made their big splash in the trade market, where they acquired Giancarlo Stanton, and the team is now trying to squeak in under the luxury-tax threshold rather than adding free agents. Perhaps in the past, slow free-agent classes could always count on the Yankees to open the pocketbook and keep the money flowing — but not this year.Before we jump to any conclusions about the owners being in cahoots, it’s worth noting that many of the explanations for this year’s issues contain at least a kernel of truth. This class of free agents is indeed mediocre — in terms of wins above replacement2Using an average of the WAR metrics found at FanGraphs and Baseball-Reference. produced by top-40 players in their previous three seasons, this is the worst crop of available talent since at least 2006.3Looking only at the most recent previous season improves this group’s standing slightly, bringing it up to sixth out of the 12 free-agent classes I examined. At the top of ESPN’s free-agent rankings, ace starter Yu Darvish is as good as any prized free agent from yesteryear, but many of the names further down the list come with legitimate issues, including Jake Arrieta’s declining value, J.D. Martinez’s inconsistent defense and Alex Cobb’s durability.It’s also true that more teams are tanking now than in years past. And the proliferation of statheads in MLB front offices over the past decade could explain why teams are no longer scrambling to offer big free-agent contracts to players who are already past their primes.As Yahoo’s Jeff Passan wrote in an excellent column last week, that final point is part of a bigger issue with the fundamental way baseball’s economics works, particularly as younger players generate more and more of the game’s on-field value. But if teams are suddenly realizing the folly of free agency, it’s also worth asking why they’ve chosen to simultaneously make their stand this year. (Bad deals still got made last season, though perhaps not as many as in the past.) The alternative explanation — collusion — is notoriously difficult to prove, however, and seems like an unbelievable risk for a group of owners who are already making money hand over fist.But the simple truth is that we don’t really know why the market for free agents is so sluggish this year. We can only prove that it is indeed historically slow-moving — and that fact alone demands an explanation. Something strange is happening with the baseball hot stove this winter. Not only is it not hot, it almost seems like it’s off.Available stars who would ordinarily have been snapped up long ago are still sitting on the shelf, which has the MLB Players Association panicking — and looking for answers. Is this simply a weak class of free agents? Have all 30 teams finally figured out that spending boatloads on veterans is usually dumb? Is the gap between contending and tanking teams to blame? Or is it just — gasp! — collusion, like the kind owners engaged in three decades ago?It’s difficult to pin down exactly why this offseason has proceeded so slowly. But the sluggish pace it has taken is quantifiable — and eye-catching. I gathered data on ESPN’s top 40 free agents1For all players ranked 40th or better on ESPN’s yearly free-agent rankings. In some years, the rankings skipped numbers, presumably because some players were ranked but did not actually hit free agency. This means that the top 40 doesn’t always include a full 40 players. for each winter going back to the 2006-07 offseason and tracked how many days it took after the end of World Series before those top players were signed. (Players technically become free agents the morning after the World Series ends.) For instance, today is Day 82 since the Astros beat the Dodgers in Game 7 of the Fall Classic, and only 43 percent of the top 40 free agents — including only two of the top 10 — have put pen to paper. How abnormal is that? Between 2006 and 2016, the average offseason saw 76 percent of the top 40 free agents inking deals by Day 82 of the offseason.Here’s what this offseason looks like so far compared to how long it usually takes for top free agents to sign:
Google workers staged a worldwide walkout last year. James Martin/CNET Google workers on Friday held a town hall meeting to discuss alleged retaliation from the search giant over employees’ activism and organizing efforts. The company’s employees booked rooms for viewing the town hall from Google offices all over the world, according to an employee who attended the meeting. At the gathering, Google workers pledged to protect each other from retaliation and brainstormed ideas to help. Some of that action could take place as soon as next week, that employee said.That employee also said it was the first big town hall meeting that Google’s temporary workers, vendors and contractors — known as TVCs in Google parlance — were able to attend, since the gathering was held by employees and not management.The meeting was called after two workers who helped to organize a massive employee walkout said management was unfairly targeting them. In November, roughly 20,000 Googlers walked out of the company’s offices worldwide to protest its handling of sexual assault allegations directed at key executives. The demonstration drew international attention. One organizer, Meredith Whittaker, who leads Google’s Open Research program, said earlier this week that she was asked to choose between Google and her outside work. Whittaker co-founded New York University’s AI Now Institute, a research center that examines the societal effects of artificial intelligence. Whittaker said Google asked her to give up that work after the company disbanded its own AI ethics board last month amid controversy over one of its members. Claire Stapleton, a marketing manager at Google-owned YouTube, said she was told after the walkout she’d be demoted and lose half of her reports. She said she was also told to go on medical leave even though she wasn’t sick. Google only walked back her demotion after she hired a lawyer, Stapleton said. “Meredith and Claire were bold and unwavering,” the employee who attended said. “The support was overwhelming and it looks like the company’s misguided gamble to cut off the ‘head’ of the organizing against harassment, discrimination and unethical decision-making won’t work.”Google employees have largely been the poster children for protest in the tech industry — a sector where rank and file workers have historically refrained from publicly criticizing management. Aside from the handling of sexual assault accusations, Google workers have also protested the company’s military contracts, its work in China, and its treatment of temporary workers and contractors. Outside of Google, other tech workers have also been speaking up. At Amazon, thousands of workers signed a letter earlier this month that urged the company to reduce its carbon footprint and take action against climate change.The town hall meeting comes a day after Google released its workplace policy guidelines, including its rules on retaliation. Retaliation means taking an adverse action against an employee or TVC as a consequence of reporting, for expressing an intent to report, for assisting another employee in an effort to report, for testifying or assisting in a proceeding involving sexual harassment under any federal, state or local anti-discrimination law, or for participating in the investigation of what they believe in good faith to be a possible violation of our Code of Conduct, Google policy or the law. The section concludes by warning employees that not all complaints may meet that definition.”If you report something that is not a policy violation and you believe you are being treated adversely as a result, you should feel free to report that and we will look into it, but it may not amount to retaliation under this policy,” the guidelines say.Google declined to comment on the town hall, but a spokeswoman said the company prohibits retaliation and has a “very clear policy.” “To make sure that no complaint raised goes unheard at Google, we give employees multiple channels to report concerns, including anonymously, and investigate all allegations of retaliation,” the spokeswoman said.

After raising funds worth ₹2,500 crore this month, online cab aggregator Ola is now the third-most valuable venture-backed company in India after Flipkart and Snapdeal.The Bengaluru-based company’s valuation rose to ₹15,600 crore with the latest round of funding which included investments by Russian billionaire Yuri Milner’s DST Global, Singapore’s state investment arm GIC and New York-based hedge fund Falcon Edge Capital invested along with its existing investors.Founded in 2011 and operations in more than 65 cities currently, the company plans to use the funds to expand its services to new cities and diversify its presence to other business areas, following the acquisition of rival TaxiForSure last month.”We will scale up rapidly and double our products and engineering team to about 1,000 in the next quarter,” Bhavish Aggarwal, CEO of OlaCabs, told The Economic Times.The company is aiming to expand cab aggregation services to about 200 smaller towns and cities, investing about of quarter of latest funds to scale up business of TaxiForSure. Ola claims to have 80% of market share after merging TaxiForSure.”Our growth has been strong and we have a very strong market leadership position, which are key reasons for our investors being so supportive,” said Aggarwal.In the previous round of funding, Japan’s SoftBank invested $210 million in the company in October 2014, taking its valuations to about $650 million.With valuations next to only Flipkart and Snapdeal, the company is trying to compete with Uber, a US-based online cab aggregator.Uber is currently the second most valuable start-up in the world at $41 billion after Chinese smartphone maker Xiaomi Inc. India is an important market to Uber, as it has only minor presence in the Chinese market.Flipkart is currently the most valued start-up backed by big venture capital firms, with its valuation skyrocketing to $15 billion from $1.5 billion in October 2013. In 2014 alone, the company raised a capital of around $2 billion.

Photo: UNDPDisaster management and relief minister Mofazzal Hossain Chowdhury Maya said Bangladesh always faces natural disaster due to the adverse impact of climate change.“We need to continue our efforts to protect the lives and livelihoods from natural disasters,” the minister told the launching ceremony of National Resilience Programme (NRP) at a city hotel on Thursday.The government and UN agencies have jointly initiated NRP at a cost of $12 million to sustain the resilience of human and economic development in Bangladesh through inclusive and gender responsive disaster management and disaster risk informed development, says a UNDP press release.Mofazzal Hossain Chowdhury Maya hoped the newly launched programme would further build the capacity of the relevant ministries and increase resilience to natural disasters.He called upon all the line ministries and development partners to implement the programme effectively and efficiently for disaster risk reduction in line with the government commitment to implement the Sendai Framework.Disaster management and relief ministry secretary Shah Kamal said that 18 ministries are engaged with disaster management, so effective coordination is must for sustaining the disaster risk management initiatives.He said it is essential to have strong partnership for inclusive disaster risk reduction plan to sustain the economic and human development.The secretary hopes that NRP will enhance the strategic intervention and minimise the challenges of disaster management.“The government is following Whole of Society Approach in disaster management.”Shah Kamal underscored the need for construction of 3,000 cyclone centers in line with the 7th Five Year Plan for minimising the disaster risks of vulnerable people in cyclone prone areas.Disaster management and relief ministry additional secretary and also NRP national programme coordinator Md. Mohsin presented the overview and action plan of the programme.The programme is funded by the government, Department for International Development (DFID) and the Swedish International Development Cooperation Agency (SIDA).The disaster management and relief ministry, the programming division of the planning commission, the women and children affairs and the local government division will implement the 3-year programme. The United Nations Development Programme (UNDP), UN Women and United Nations Office for Project Services (UNOPS) will provide technical support.The disaster management will focus on disability inclusive and gender-responsive capacities, the programming division will focus on the capacity for disaster and climate risk informed planning, the department of women will focus on the gender dimension of the programme and the LGED will focus on resilient infrastructure.UN resident coordinator Mia Seppo emphasised on inclusive development, resilient infrastructure, engagement of private sector in risk informed business continuity plan and integration of global commitment in national development planning.Swedish ambassador Charlotta Schlyter said Bangladesh needs the engagement of women to fight and adapt disaster and climate risks.She underscored the need for gender responsive disaster management planning for enhancing sustainable development efforts.Water resources ministry secretary Kabir Bin Anwar, local government division additional secretary Mahbub Hossain, women and children affairs ministry additional secretary Md Ainul Kabir, planning division additional secretary Kazal Islam and DFID humanitarian adviser Omar Farook, among others, addressed the event.
Malaysian prime minister Mahathir Mohamad. ReutersMalaysian prime minister Mahathir Mohamad said Wednesday he wants to develop an island on a cluster of rocks previously disputed with Singapore, a move that could anger its neighbour.The strategically located area has long been a flashpoint between Kuala Lumpur and Singapore, and they previously took a territorial dispute to the United Nations top court.The International Court of Justice in 2008 awarded two rock clusters, called Middle Rocks, to Malaysia while a nearby island was deemed to be Singaporean territory.Malaysia launched a challenge to that ruling last year but Singapore’s foreign ministry said Wednesday it had been withdrawn by Kuala Lumpur.However, at the same time Mahathir announced Malaysia wanted to develop an island on Middle Rocks, at the eastern entrance of the strategic Singapore Strait.The 100-kilometre (60-mile) strait is one of the world’s busiest commercial shipping routes, with vessels using it to access the city-state’s port.“It is our intention to enlarge Middle Rocks into a small island for us,” the 92-year-old-who started his second stint as premier this month after a surprise election win-told a press conference.He gave no more details about what the proposed island would look like or how long it would take to build.Mahathir added that Malaysia had already built a structure on Middle Rocks. Reports said Malaysia inaugurated a maritime base there last year.James Chin, a Malaysia expert from the University of Tasmania, told AFP that Singapore would see the move as “hostile”.“Among the Singapore elite, they will see it as part of Mahathir’s anti-Singapore stance,” he said.It came after Mahathir announced this week that he was scrapping a planned high-speed railway between Kuala Lumpur and Singapore, as he seeks to improve the nation’s finances.Both developments are likely to alarm the Singapore government, already wary of Mahathir’s return as ties between the neighbours were famously stormy during his first stint as premier from 1981-2003.Still, Kuala Lumpur’s decision to drop its case at the ICJ could assuage fears.Malaysia had lodged its challenge in February 2017, calling for the court to overturn its earlier ruling granting its neighbour sovereignty over the disputed island.
One way that thermophoresis inside living cells can be used is to measure the binding affinities of molecules. As the scientists explain, the binding of a fluorescently marked molecule such as DNA or a protein leads to a change in the thermophoretic depletion strength. Binding affinities can reveal more detailed information about the interactions of these molecules.”The dream would be to record binding affinities in living cells, i.e., translating the award-winning microscale thermophoresis (MST) technique of our startup company Nanotemper into living cells,” Braun said. “However, the measurement protocol is not yet robust against the shape of the cell, so some more tricks to make it work will be necessary. But we are optimistic—experimental tricks are our specialty.” More information: Maren R. Reichl and Dieter Braun. “Thermophoretic Manipulation of Molecules inside Living Cells.” Journal of the American Chemical Society. DOI: 10.1021/ja506169b Now in a new paper, researchers have demonstrated for the first time that thermophoresis—the movement of molecules due to a temperature gradient rather than an electric field—can be used to measure the movement of DNA and other molecules inside living cells. The paper, by Maren R. Reichl and Dieter Braun at the Ludwig Maximilian University of Munich, is published in a recent issue of The Journal of the American Chemical Society.”Our work shows that the measurement of thermophoresis in living cells is possible—moreover, in parallel across the cell and not at one single point,” Braun told Phys.org.In the new technique, a temperature gradient is applied across a cell by an infrared laser. Fluorescently marked molecules inside the cell move along this temperature gradient from hotter to colder regions. A camera can record this thermophoretic movement, with every camera pixel measuring thermophoresis simultaneously and independently. The technique can be performed in the natural environment of cells in vivo.The researchers demonstrated the use of thermophoresis measurements of DNA in the cytoplasm of living cells. Interestingly, the results revealed that DNA movement in the cytoplasm is slowed down, probably due to molecular crowding. In addition to measuring the movement of DNA, the thermophoresis technique could also measure the movement of proteins, pharmaceutical components, and other molecules in cells as long as they can move through the cytoplasm. Ribosomes, for example, are so large and bound to the endoplasmic reticulum that they cannot easily diffuse through the cytoplasm, making them poor candidates for thermophoresis.

Scientists have been hard at work trying to build a quantum computer for several years, and while the results have at times been promising, there is still clearly a long way to go. For such a computer to work, a quantum processor of some sort must be created. The current thinking is that such a processor will likely be photon based (because they are relatively easy to entangle and because they can be manipulated easier than other types of quantum bits) and it will have to be chip based. In this new effort, the researchers have created a process that allows for performing scalable integration of SNSPDs on several different kinds of photonic circuits.For a quantum computer based on photons to work, logic suggests, it will need to be able to detect and process single photons. SNSPDs are thought to be the most promising single photon detectors developed thus far, but, sadly, processes developed for building them have been plagued by a high numbers of defects. In this new effort, the researchers have developed a process that allows for building each detector separately, and putting only those that are defect-free onto an optical chip. The process also calls for building the optical chips separately using standard chip making fabrication techniques.The team reports that their process allows for building detector arrays that are larger and denser than those built before—and they are more sensitive as well. They proved their claims by building detectors capable of handling 20 percent of photons sent their way—ten times better than previous methods. Each was made on micron-sized membranes and those that passed testing, were transferred to a waveguide using an optical microscope.The team is continuing their research, now focusing on building larger on-chips systems with more capabilities. A large team of researchers with members from MIT, IBM, NASA’s JPL and Columbia University has developed a process that that enables scalable integration of superconducting nanowire single-photon detectors (SNSPDs) on a range of photonic circuits. In their paper published in the journal Nature Communications, the team describes their new process and why they believe it may lead one day to a practical photonic quantum processor on a chip.

The input light travelled along the 500-nm-wide waveguide (IV) over a distance of 2 mm before reaching a 50:50 beam splitter (directional coupler in V) followed by the waveguide-integrated detectors (VI).

A central goal is to integrate single-photon detectors to reduce optical losses, latency and wiring complexity associated with off-chip detectors. Superconducting nanowire single-photon detectors (SNSPDs) are particularly attractive because of high detection efficiency, sub-50-ps jitter and nanosecond-scale reset time. However, while single detectors have been incorporated into individual waveguides, the system detection efficiency of multiple SNSPDs in one photonic circuit—required for scalable quantum photonic circuits—has been limited to <0.2%. Here we introduce a micrometer-scale flip-chip process that enables scalable integration of SNSPDs on a range of photonic circuits. Ten low-jitter detectors are integrated on one circuit with 100% device yield. With an average system detection efficiency beyond 10%, and estimated on-chip detection efficiency of 14–52% for four detectors operated simultaneously, we demonstrate, to the best of our knowledge, the first on-chip photon correlation measurements of non-classical light.via Nanotechweb Journal information: Nature Communications © 2015 Phys.org Packing single-photon detectors on an optical chip to create quantum-computational circuits This document is subject to copyright.

She is starring in the upcoming film about Apple co-founder Steve Jobs, but Oscar-winning actor Kate Winslet says she is not good with technology.The 40-year-old actor is mother to a 15-year-old daughter, an 11-year-old son and her youngest son will turn two in December, reported BBC online.“I’m terrible. I am the least techie person you will ever meet, I’m rubbish. “We’re not a big deviced-up household. We don’t have any social media, nothing like that,” she said.Asked if she is strict with her children about how much they can use technology, Winslet said, “Not strict. But you have to have rules I think and we certainly have those, yes.”
