Operation times can be extended if solar power is used in conjunction with batteries, as in Qinetiq’s ultralight Zephyr, which has been able to fly for 82 hours. Solar Impulse, a Swiss company, has also demonstrated solar powered piloted craft.Unmanned vehicles used by the military tend to be stronger and heavier than ultralights, and it is difficult to power them with solar power because of their greater energy requirements, and this is where LaserMotive hopes to provide a solution.The laser-powered model helicopter, which weighed only 22 grams, was demonstrated at Denver, Colorado last week at the AUVSI Unmanned Systems Conference. The tethered, radio-controlled model helicopter was powered by an array of semiconductor-diode near-infrared lasers, which produced laser beams that were then focused down to a single beam seven centimeters in diameter. The beam, which will not damage eyes, tracked the helicopter automatically and illuminated the helicopter’s photovoltaic (PV) cells, which were optimized for the laser’s wavelength. The PV cells then converted around 50 percent of the laser power to electricity, providing just a few watts, but enough to keep the helicopter rotors spinning.Tom Nugent, president, CEO and co-founder of LaserMotive, said he believed the six hour limit was set by the quality of the motor that drives the helicopter rotors, since it was only a small brush motor not designed to run continuously for that long. The tiny model flies under laser power until the motor burns out, he said. Nugent also said he expected the system could be scaled to “anything anybody is interested in.” An unmanned vehicle could fly missions and return to recharge over the laser, or could hover over a laser base for lengthy periods. LaserMotive demonstrated the use of lasers to power robots wirelessly last year, when it won the $900,000 Power Beaming Challenge sponsored by NASA for using a laser to power a robot climbing a 900-meter-long cable suspended from a full-scale helicopter. center_img Citation: Lasers keep mini helicopter hovering for hours (2010, September 9) retrieved 18 August 2019 from https://phys.org/news/2010-09-lasers-mini-helicopter-hours.html Multi-mission UAV, recharging in between missions.

Other possible applications include delivering emergency power in disaster situations and to forward military bases or remote rural communities.UAVs are among the fastest growing sectors in the aerospace industry and in defense, and the global market is expected to grow from the current $4.9 billion to $11.5 billion within ten years, according to industry analysts the Teal Group.last_img read more

Archeologists unearth eight Bronze Age boats at British Quarry

first_img © 2013 Phys.org More information: Cambridge Archaeological Unit: www-cau.arch.cam.ac.uk/index.htmvia Independent, Telegraph, Guardian. Explore further (Phys.org) —Archeologists from Cambridge Archaeological Unit have unearthed 8 Bronze Age wood boats from a quarry in Britain. The boats are believed to have been carved by people living in the area approximately three thousand years ago and were for unknown reasons buried intentionally. Citation: Archeologists unearth eight Bronze Age boats at British Quarry (2013, June 5) retrieved 18 August 2019 from https://phys.org/news/2013-06-archeologists-unearth-bronze-age-boats.htmlcenter_img The quarry is approximately 150 miles north of London in an area near Peterborough called Cambridgeshire—its owned and operated by Hanson UK (who is also funding the excavation) and is part of Must Farm, a brick making company. The boats were first found in 2011—since that time, excavators have dug them out of the dry (River Nene) bed and transported them to another archeology site—Flag Fen—for preservation processing. The boats are currently being housed in a cold storage facility to prevent the wood from rotting. Visitors that wish to view the work can peer through windows.The boats were all carved from single tree trunks (six oak, one alder and one lime) and range in size from small single person watercraft to large vessels capable of carrying up to 20 people or a tonne of cargo. Researchers working on the project suspect the boats were all sunk intentionally because the transoms had been removed and were not found at the site. Transoms are flat thin boards that fit into slots at the rear of boats. When in the slots they prevent water from entering the boats—when removed, they allow the boat to fill and sink. To sink the Bronze Age boats would have required extra effort however, as they were made of nothing but wood. The research team doesn’t know why the boats were sunk or why they were never recovered.The area near where the boats were found came to be naturally flooded approximately 4000 years ago, necessitating adaption by the people who lived there. Archeological evidence suggests they learned to carve boats out of tree trunks and used them to move around, to transport goods and animals and of course to catch food.All of the boats have been well preserved and represent the largest number of Bronze Age boats ever found at one location. The archeologists studying them report that all of the boats were heavily used and most show signs of having been repaired. One also sported etched criss-cross patterns inside and out.

New polymer can shapeshift into multiple forms w video

first_img This document is subject to copyright. Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. © 2016 Phys.org In the recent past, material scientists have come up with polymers that change from one shape to another when heated or cooled—the main drawback for them has been that they can only be programmed to take one or two shapes. In this new effort, the researchers have come up with a polymer that is capable of forming itself into many different shapes, by combing two ingredients—one that has elastic deformation properties and the other that has plastic deformation properties. Current polymers tend to have the former property, which is useful for some limited applications. But what has really been needed, the team notes, is a polymer capable of plastic deformation, where it is re-shaped permanently without having to resort to melting—due to covalent bond exchange.To make the polymer, the researchers added the chemical 1,5,7-triazabicyclo[4.4.0]dec-5-ene to an elastic material known as crosslinked poly (caprolactone) , the result was a plastic that had a low transitive temperature (55˚C) and a high deformation temperature (130˚C). The new material can be programmed by physically pushing the material into different shapes at different temperatures. To make them come about on demand, the material is subjected to the temperature that corresponds with the shape that is desired. The group created several such polymers and demonstrated that it was possible to cause the same piece of material to fold itself into first one shape, then another—in one such example a material was first caused to revert to an origami boat and then to revert to an origami flower. New self-stretching material developed (Phys.org)—A team of researchers with Zhejiang University in China has developed a new type of polymer that can be caused to revert to multiple different forms on demand. In their paper published in the journal Science Advances, the team describes how they came up with the new polymer, how it works and the uses to which it might be put.

DOI: 10.1126/sciadv.1501297AbstractStimuli-responsive materials with sophisticated yet controllable shape-changing behaviors are highly desirable for real-world device applications. Among various shape-changing materials, the elastic nature of shape memory polymers allows fixation of temporary shapes that can recover on demand, whereas polymers with exchangeable bonds can undergo permanent shape change via plasticity. We integrate the elasticity and plasticity into a single polymer network. Rational molecular design allows these two opposite behaviors to be realized at different temperature ranges without any overlap. By exploring the cumulative nature of the plasticity, we demonstrate easy manipulation of highly complex shapes that is otherwise extremely challenging. The dynamic shape-changing behavior paves a new way for fabricating geometrically complex multifunctional devices.last_img read more

A journey shared on canvas

first_imgSharing the experience of 40 years, artist Niren Sengupta is ready with his solo exhibition titled Sublimity- A Painter’s Quest. The show will display forty works of the painter created at different points of his journey through the years.The artist invokes motifs from animal world, birds, contemporary life, picturesque sightings and spiritual existences. Lord Krishna, Lord Rama,  Lord Buddha and monks dance on his canvases in ecstasy and bliss. He believes that art is an expression of inner language. Also Read – ‘Playing Jojo was emotionally exhausting’The subjects are varied which he treated differently at different points of his journey. He deploys the idea of shringar from Natyashastra Shastra in every painting. He moves beyond the trance to the romance with maturing figures’ thought and struggle. The artist seems to have given enough thinking space to the spectator to understand the mood of the painting.The paintings deal with abstracts followed by the saranagata series (surrender to the divine). They are linked in more than one ways. His abstracts have a perspective and the natural force. The works are more an example of light and shade, and competing movements of organic wings and boat-like contrasts against blues, reds and mauve background.Where: Visual Arts Gallery, India Habitat Centre, Lodhi RoadWhen: Till 7 AugustTimings: 11 am to 8 pmlast_img read more

Dystopian attraction of Stalin era

first_imgSome of the most memorable, enduring literature has been inspired by history’s bloodiest eras – the French Revolution, trench warfare in World War I, the Spanish Civil War, the Nazi killings, the partition of India and its dangerous dislocations, the Cambodian, the Rwandan genocides and so on. But these are not only intended as harrowing records of those turbulent times but a warning against their recurrence. So is it about the Stalin era with its pervasive paranoia and fear, violent purges, mass repression, ‘justice’ dealt on torture-achieved confessions and denunciations, historical manipulation – and an over-arching personality cult. Also Read – ‘Playing Jojo was emotionally exhausting’Stalin succeeded Lenin in 1924 but it was only a decade later that the terror began. The Great Purge, targeting all institutions and supplanting any rival, would continue till 1940, when perforce halted by World War II, resume afterwards – though in smaller scale – and end only with his death in 1953. Though it was first officially acknowledged in Khrushchev’s Secret Speech at the 20th Party Congress in 1956, some authors had brought some aspects to public attention much earlier. Also Read – Leslie doing new comedy special with NetflixThere are some indications in Mikhail Bulgakov’s The Master and Margarita but the first published record is Hungarian-born British writer Arthur Koestler’s Darkness at Noon (1940), the account of an old Bolshevik’s arrest for ‘treason’, torture for ‘confession’ and eventual execution. Though the character is called Rubashov, he may well be named Bukharin, Zinoviev, Kamenev or any other of Lenin’s old associates eliminated in the purges.George Orwell’s allegorical novella Animal Farm (1945) is a sharp attack on Stalin’s rise and reign, while the more terrifying, dystopian 1984 (1949) has, as the state’s figurehead, the dark-eyed, heavy moustachioed Big Brother (an unmistakable description).Then there is Ilya Ehrenburg’s The Thaw (1954) – the first Russian work to allude to Stalinist terror, and Alexander Solzhenitsyn’s One Day in the Life of Ivan Denisovich (1962) influencing other books on gulag existence.Even well into the new century and far from Russia, the period still attracts authors and has led to some engrossing works which recapture the tense, perilous atmosphere. The pride of place must go to Simon Sebag-Montefiore’s Sashenka (2008) and One Night in Winter (2013), both loosely linked with some common characters, both real and fictional.Sashenka begins in Tsarist St Petersburg in 1916 when the eponymous heroine – a willful teenager – spurns her privileged background to join the Bolsheviks and ends up as a secretary to Lenin. In 1939, she is long married to a leading figure of the regime, who survived the purge and is so trusted that one night Stalin and his entourage drop in for dinner.But one moment of indiscretion is all needed to unravel her and her family’s life. In the third part set in the 1990s, some dedicated researchers, funded by an Russian oligarch, uncover her shocking fate and that of her two children.One Night in Winter, set in World War II’s aftermath, is no less stomach-wrenching as the escapades of a bunch of a privileged teenagers go tragically wrong and enmesh their parents – all members of the ruling elite – in a relentless witch-hunt, powered by a power struggle between rival intelligence chiefs – Beria and Abakumov. The teenagers have to inform on each other and their parents while their siblings as young as six and 10 years are also picked up and threatened. Meanwhile, the parents have to go on as nothing has happened.Another view of the claustrophobic times and the innumerable pitfalls – especially for a honest man – is offered in William Ryan’s series about a mid-1930s Moscow police captain, probing a range of criminal cases – all with sinister political ramifications and perils galore for the investigator. Debuting in The Holy Thief (2010) where a murder case grows complicated once it is found the woman victim is American, Captain Alexei Dimitrevich Korolev is next sent to a film location in Ukraine (The Bloody Meadow, 2011) to probe the ‘suicide’ of a woman – reportedly in a relationship with then NKVD chief Yezhov. Then he has to investigate a killing of scientists right in view of the Kremlin in The Twelfth Department (2012), while trying to ensure the safety of his family from the state.Stalin prominently features in the Inspector Pekkala series by American author Paul Watkins (pen name Sam Eastland) but these deserve separate treatment for a most innovative treatment of the era and his depiction – ranging from almost reasonable to painfully paranoid and untrustworthy. On the other hand, readers interested in historical treatment could pick up Sebag-Montefiore’s Stalin: The Court of the Red Tsar (2005) and Orlando Figes’ The Whisperers: Private Life in Stalin’s Russia (2007).last_img read more

Be positive to keep heart disease at bay

first_imgPeople with a positive psychological state such as those who are enthusiastic or interested are likely to develop long-term healthy habits that are important for lowering the risk of heart disease, says a new study.The researchers found that patients who reported higher positive psychological states were more likely to be physically active, sleep better and take their heart medications and were also less likely to smoke, compared to patients with lower levels of positive states. “Negative emotions and depression are known to have harmful effects on health, but it is less clear how positive emotions might be health-protective,” said Nancy Sin, postdoctoral fellow at Pennsylvania State University in the US.  Also Read – ‘Playing Jojo was emotionally exhausting’“We found that positive emotions are associated with a range of long-term health habits, which are important for reducing the risk of future heart problems and death,” Sin noted.The researchers assessed psychological well-being of participants at baseline and again at a five-year follow-up. Physical activity, sleep quality, medication adherence and alcohol and cigarette use were also measured at baseline and again five years later. Higher levels of positive emotions were associated with less smoking, greater physical activity, better sleep quality and more adherence to medications at baseline, the study found. They found no correlation between positive emotions and alcohol use.  “Efforts to sustain or enhance positive emotions may be promising for promoting better health behaviours,” the study said.The findings appeared in the journal Psychosomatic Medicine.last_img read more

Govt introduces Bangla Krishi Sech Yojana to help small marginal farmers

first_imgKolkata: The state government has introduced the Bangla Krishi Sech Yojana to extend support to farmers in setting up micro irrigation facilities that will ensure cultivation using less amount of water.The project will be immensely helpful to small and marginal farmers, mainly in the Jangalmahal area. The state cabinet has given approval to the project on Wednesday.It may be mentioned that there are some places in districts including Purulia and Bankura, which receive scanty rainfall and the technology that will ensure cultivation of crops, mainly fruits and vegetables, using less water, will be of great help to the farmers. Also Read – Rain batters Kolkata, cripples normal lifeThe state Agriculture department had taken an initiative and identified that two artificial processes – drip irrigation and sprinkle irrigation – will help in cultivation on more acres of land by using less quantity of water.Necessary trials and tests proved both the processes to be useful in ensuring cultivation with less water. Subsequently, a proposal was given to Chief Minister Mamata Banerjee in this connection and the cabinet has given its nod for the same on Wednesday. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedHowever, it was found that it would not be possible for the small and marginal farmers to bear the cost of the drip irrigation and sprinkle irrigation mechanisms, which cost around Rs 70,000 and Rs 20,000 respectively, per acre of land.So, the state government has allotted around Rs 35 crore for the project, thanks to which farmers are going to get the facilities completely free of cost.Since it is a continuous process, the amount would go up later with the success of the project.It has been learnt that experts will be engaged to support the farmers to carry out the project. The experts will develop the mechanisms for individual farmers and at the same time, they will also provide necessary support to farmers to become familiarised with the same.The state government will make the payment to the experts only after receiving a feedback from the farmers and proper scrutiny of the same.last_img read more

LoP asks LG to inquire advocate appointments by AAP govt

first_imgThe only thing that went in favour of the Delhi Chief Minister Arvind Kejriwal in the judgment of Delhi high court on Friday was the appointment of advocates but BJP has now demanded the LG to order inquiry into these appointments.“The precious public exchequer is being squandered by the CM for his upmanship. As a Leader of Opposition, I am being denied the information regarding engagement of advocates and case-wise payments made to the lawyers,” said Vijender Gupta alleging crores are being paid to the senior advocates by the Delhi government.“I urge the LG to constitute a High Level Inquiry Committee to probe into the engagement of large number of advocates and payment of crores of rupees as fees to them,” he added. He claimed that he wrote several letters to the Chief Secretary for providing information on the fee paid to the advocates but he did not provide the information so far. “The AAP government is deliberately hiding information on payments made to lawyers,” alleged Gupta. He also alleged that payment to contractual lawyers and salary to prosecutors were hiked to around 600 per cent to benefit lawyers associated with AAP.last_img read more

WB board Class X question papers to be opened before students

first_imgKolkata: In a departure from the norm, the West Bengal Board of Secondary Education (WBBSE) on Tuesday announced that question paper packets will henceforth be opened in front of Class 10 candidates, shortly before the commencement of the examination. Earlier, the sealed packets were broken in the office of the institution’s headmaster and papers sorted accordingly before distribution among the students. “From 2019, the sealed question packets of Madhyamik examination (Class 10 board exam) will be opened by invigilators in front of students in the examination hall and distributed accordingly,” board president Kalyanmoy Ganguly said. Also Read – Rain batters Kolkata, cripples normal life Sources said the WBBSE decision came in the wake of reports that the headmaster of a Jalpaiguri school, during the 2018 secondary examination, opened sealed question papers 35 minutes before the scheduled time. The headmaster was suspended by the board after he failed to give a satisfactory reply to a showcause notice issued to him. There were also reports of question paper leak on WhatsApp in 2017, but the board, back then, asserted that the paper circulated was “fake”. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed Ganguly said the WBBSE members, along with officer in-charge of local police station and a district administration official, will hold meetings with the head of examination centres to ensure that the measures were implemented without glitches. “This time, the number of question papers in the packets will tally with the number of examinees in the hall. There will be no sorting beforehand,” he said. The new measure was aimed at ensuring that exams were conducted in a transparent manner, Ganguly added.last_img read more

One Time Traffic Fine Settlement scheme garners huge response

Officials also informed that there is no provision of extension of the scheme. The scheme is strictly for one time as per the government notification. It was also informed that many people whose cases have been sent to the court want to clear using the scheme. But that is not possible as it is only for those cases which are not listed with the concerned court. Sources informed that on seeing the response, all the traffic guards have been asked to communicate with the vehicle owners which are on the list sent by the Traffic department and ask them to submit the fine and properly inform them about the scheme.last_img read more

Bengali film screening cancelled sitin protest planned

first_imgKolkata: A day after the screening of his film “Bhobishyoter Bhoot” was cancelled, director Anik Dutta on Sunday said he was yet to get any “official communication” though people have offered support and asked him to join a sit-in protest. “Still, I haven’t got any official communication’ regarding the cancellation, all they said was that the instructions were from higher authorities. But I have received immense support and the film fraternity has shown great solidarity,” Dutta said. Also Read – Bose & Gandhi: More similar than apart, says Sugata Bose The film, released on Friday, is a comedy that explores the current political scenario. On Saturday, it was taken off from almost all multiplexes and single screen theatres in West Bengal for “political reasons”. Dutta mentioned that various groups have planned to organise a sit-in protest at Metro Y Channel on Sunday for upholding the democratic rights. “I have been invited by them. Senior film personalities like Soumitra Chatterjee will send their support via letters.” Also Read – Rs 13,000 crore investment to provide 2 lakh jobs: Mamata Asked if they would face a problem with the venue, he said: “The organisers will seek permission, if given fine else we will move. We will not be aggressive in any way and also the Chief Minister sat there on a protest few days back.” Earlier, the Mamata Banerjee-led government had imposed a ban on protests at the Metro Y Channel citing traffic disruption. But on February 1, she held a 45-hour sit-in at the Metro Y Channel following a face-off between the city police and the Central Bureau of Investigation (CBI). Dutta had approached a multiplex-chain in a city-based mall on Saturday where they said that the “film cannot be shown”. Expressing shock and dissatisfaction Dutta had earlier said: “The screening has been stopped even after the film was passed by the censor board without any major cuts. The hall owners are responsible for running the film and I seek an answer from the ones who have given them instructions.” “This film criticises all political parties without taking any name, then how can there be any issue of intolerance. We want to know what is the exact problem,” said critically acclaimed actor Kaushik Sen, who features in the film. Dutta is known for his 2012 blockbuster film “Bhooter Bhabishyat”. The current release is not a sequel and the only similarity is that both are ghost films of the satiric genre.last_img read more

He has multiple companies working to automate his business so he can concentrate on increasing his profits.Here are some ways eBay’s many resources can help automate your business and increase efficiency.Shipping: Avoid long lines at the post office with eBay’s Shipping Center. You can print postage online, learn about your shipping options and schedule mail pickups at your home or business.Many PowerSellers use Endicia. In addition to printing your postage at home, for a starting price of $9.95 a month you can print international customs forms, add marketing information to your labels, automatically verify shipping addresses, look up the status of shipments, take advantage of wholesale insurance and much more. “Endicia Premium has allowed my business to grow both domestically and internationally,” says Prete, 30. “Up to one-third of my business is overseas, and Endicia Premium makes printing customs forms a breeze. Just a few signatures, and my international packages are good to go–no waiting in line at the post office.”Communication: Adding another “employee” will cost you less than $1 an hour. Using the Selling Manager products lets you fully automate your e-mails and feedback for your buyers. These tools start at $4.99 and can easily save you up to 15 hours a month in time spent communicating with buyers. Listing: Doing your listings on eBay can be the most time-consuming task of your business. There are numerous listing management tools in the marketplace. Prete uses eBay Blackthorne Pro because it integrates with his other tools, including Selling Manager Pro and Endicia. “This gives me the flexibility I need for my business,” Prete says.Need help deciding which tools are right for your business? eBay has a great resource at http://pages.ebay.com/sell/toolrecommendations.html. You can also check out eBay’s Certified Providers at http://developer.ebay.com/programs/certifiedprovider/catalog.Don’t assume that a task is free if you do it yourself. Doing it yourself actually costs you money if the time consumed by these tasks keeps your business from growing. As Prete says, “These tools have enabled me to continue to work alone while allowing my business to expand.”Janelle Elms, eBay University instructor and dean of eBay Business for LA College International, is the creator of the eBay Stores Video Series. 3 min read This story appears in the February 2007 issue of Entrepreneur.

Mobile App Marketing 101 How to Spread the Word About Your App

first_img Enroll Now for Free Marketing begins the day you put your mobile app idea into production. But not everyone has a budget for marketing. Contrary to popular belief, most effective marketing strategies don’t require any spending at all. In my last column, “4 Essentials for Successful Mobile Apps,” I offered advice on what makes a mobile app successful, with one of the key ingredients being a well-thought-out marketing strategy. But how to put that strategy in place?From the period before you launch your app to after it goes on the market, here are six important marketing strategies. While they may require time and perseverance, they involve little or no money:Make your press kit pop. Your press kit should include information about the problem you’re solving, but not enough detail to completely give the product away. Key components include a high-resolution logo, sample design screens, an app icon, a press release, a microsite and a teaser video. Make sure you have a fantastic name and icon for your app that’s catchy and connects with the audience instantly. The first paragraph of the app description should be your selling pitch and app store screenshots should be customized to attract your customer.One of the most under-rated, but highly effective strategies is app store marketing. Because a lot of people browse with keyword searches, select your keywords wisely by researching successful competitors.Build an enticing microsite. This two to three page website aggregates all the information about the product. While a lot of downloads will come directly through app stores, a huge amount of traffic is driven through the web. For example, the Path app’s microsite homepage greets visitors with the tagline: “Private messaging and sharing with friends and family” directly above a sign-up prompt at the top of the page. This is designed to hook new user as soon as they hit the landing page, before they’ve gotten all the information they need on the app.Create a teaser or giveaway campaign. Build a teaser or giveaway offer into your microsite and invite people to share their email address to stay updated on when your app launches. This helps build a database of people interested in your app. For example, a teaser video that came out before an app called Analog Camera came out last month, offered demos of how the app would work without going into a full explanation or revealing the release date. Instead the video lead you to a microsite with the message: “Sign up and you’ll be the first to know when Analog Camera launches!” — a clever way to gather potential customers early.Keep content fresh. Do this by creating a blog linked to your microsite. This is important because blog posts are indexed by Google. Keeping your content fresh will drive a lot of inbound traffic to your website. You can also make your presence cohesive on social media platforms like Twitter, Facebook, Linkedin, Digg and Stumbleupon by sharing your blog posts with an active audience. Always think about how your content can be of value to a follower. For example, Angry Birds’ social media strategy includes sneak peeks of new game levels and versions, special offers and real-life examples of people enjoying the game.Build hype. Once your app is ready to be submitted to the app store, be sure to set a release date and plan publicity around the launch.Get in touch with tech blogs and publications likely to write about your product. Personalize your email with links to the press kit and microsite. If you haven’t heard from them in a week, send a reminder. If they did not cover your product initially, reach out again after your launch with download statistics and customer testimonials.Some popular sites like 148 Apps, App Advice and Macworld can help spread the word about your app. After it launches, write to them for a review of your app. There’s a large audience that reads recommendations online when deciding what to download.Ask customers for feedback. The more positive the ratings are for your app, the better chance it has of being downloaded. That’s why it’s worth it for you to build a code into your application asking users to rate it. Make sure to include contact information at the end of your app description or use a software development kit such as Appsfire to let people send feedback from a notification inbox. You can then reach out to unhappy users, resolve their issues and ask them to leave a rating on the app store if they were satisfied. Converting unhappy users to happy ones will improve your ratings.The main investment in these tactics is your time, persistence and creativity. Armed with these three qualities, you can get over a million eyeballs for your app in a very short time. Opinions expressed by Entrepreneur contributors are their own. This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience.

New Crop of Robots to Vie for Space in the Operating Room

first_img Free Webinar | Sept 5: Tips and Tools for Making Progress Toward Important Goals Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. Even though many doctors see need for improvement, surgical robots are poised for big gains in operating rooms around the world.Within five years, one in three U.S. surgeries — more than double current levels — is expected to be performed with robotic systems, with surgeons sitting at computer consoles guiding mechanical arms. Companies developing new robots also plan to expand their use in India, China and other emerging markets.Robotic surgery has been long dominated by pioneer Intuitive Surgical Inc., which has more than 3,600 of its da Vinci machines in hospitals worldwide and said last week the number of procedures that used them jumped by 16 percent in the second quarter compared to a year earlier.The anticipated future growth — and perceived weaknesses of the current generation of robots — is attracting deep-pocketed rivals, including Medtronic Inc. and a startup backed by Johnson & Johnson and Google. Developers of the next wave aim to make the robots less expensive, more nimble and capable of performing more types of procedures, company executives and surgeons told Reuters.Although surgical robots run an average of $1.5 million and entail ongoing maintenance expenses, insurers pay no more for surgeries that utilize the systems than for other types of minimally-invasive procedures, such as laparoscopy.Still, most top U.S. hospitals for cancer treatment, urology, gynecology and gastroenterology have made the investment. The robots are featured prominently in hospital marketing campaigns aimed at attracting patients, and new doctors are routinely trained in their use.Surgical robots are used in hernia repair, bariatric surgery, hysterectomies and the vast majority of prostate removals in the United States, according to Intuitive Surgical data.Doctors say they reduce fatigue and give them greater precision.But robot-assisted surgery can take more of the surgeon’s time than traditional procedures, reducing the number of operations doctors can perform. That’s turned off some like Dr. Helmuth Billy.Billy was an early adopter of Intuitive’s da Vinci system 15 years ago. But equipping its arms with instruments slowed him down. He rarely uses it now.”I like to do five operations a day,” Billy said. “If I have to constantly dock and undock da Vinci, it becomes cumbersome.”Surgeons’ wish listTo gain an edge, new robots will need to outperform laparoscopic surgery, said Dr. Dmitry Oleynikov, who heads a robotics task force for the Society of American Gastrointestinal and Endoscopic Surgeons.Surgeons told Reuters they want robots to provide a way to feel the body’s tissue remotely, called haptic sensing, and better camera image quality.New systems also will need to be priced low enough to entice hospitals and outpatient surgical centers that have not yet invested in a da Vinci, as well as convince those with established robotic programs to consider a second vendor or switching suppliers altogether.”That is where competitors can differentiate,” said Vik Srinivasan of the Advisory Board Co., a research and consulting firm that advises hospitals.Developers say they are paying attention. Verb Surgical, the J&J-Google venture that is investing about $250 million in its project, said creating a faster and easier-to-use system is a priority.Verb also envisions a system that is “always there, always on,” enabling the surgeon to use the robot for parts of a procedure as needed, said Chief Executive Scott Huennekens.Intuitive said it too is looking to improve technology at a reasonable cost, but newcomers will face the same challenges.”As competitors come in, they are going to have to work within that same framework,” CEO Gary Guthart said in an interview.Device maker Medtronic has said it expects to launch its surgical robot before mid-2018 and will start in India. Others developing surgical robots include TransEnterix Inc. and Canada’s Titan Medical Inc.An RBC Capital Markets survey found that U.S. surgeons expect about 35 percent of operations will involve robots in five years, up from 15 percent today.J&J, which hopes to be second to market with a product from Verb, has said it sees robotics as a multibillion-dollar market opportunity. Huennekens said Verb’s surgical robot will differ from another Google robotics effort, the driverless car, in one important aspect.”There will always be a surgeon there,” he said.(Reporting by Susan Kelly; Editing by Michele Gershberg and Lisa Girion) This story originally appeared on Reuters July 28, 2016 4 min read Register Now »last_img read more
