Pakistan hockey players celebrate after scoring a goal against IndiaThe Indian men’s hockey team went down fighting 1-2 to arch-rivals and defending champions Pakistan in a keenly contested Pool B match of the 17th Asian Games at the Seonhak Hockey Stadium here Thursday.With the loss, India’s two-match winning streak came to an end. India are currently placed second in the group behind Pakistan.After a barren first two quarters, Pakistan took the lead in the eighth minute of the third quarter when Muhammad Umar Bhutta scored from a rebound. Nikkin Thimmaiah drew level for India in the 53rd minute by tapping home Kothajit Singh’s cross from the left flank. Pakistan restored their lead a minute later through Muhammad Waqas and held on to win their third consecutive group match.The high-voltage clash saw a neck-and-neck fight till the last minute. Playing as per expectations, both the teams displayed enormous amounts of strength and skills. India challenged their arch-rivals in all quarters but went down fighting.Both India and Pakistan showcased extreme attack and powerful defence, restricted each other from opening the goal account in the first two quarters of the game. It were Pakistan who managed the first breakthrough in the 38th minute when Bhutta sneaked in a field goal from a goalmouth melee and opened the account for the Greenshirts.Going into the fourth quarter, India went full throttle on the opponents D and drew the game in the 53rd minute when Thimmaiah sliced in a field goal that left Pakistan stunned.advertisementHowever, in the next minute, Waqas scored the second goal for Pakistan. India intensely fought back for the rest of the match to try and level the score but were unsuccessful in their efforts, and eventually lost the match by 1-2.India will be playing their last pool match against China, Saturday.
The match will be a repeat of the 2010 NYC final, which saw QSST defeat NSWCCC by two touchdowns, 8-6. The teams have had a great rivalry over recent years, with NSWCCC winning the title the year prior, at the 2009 event.Stay tuned to the website throughout the day to keep up-to-date with all of the latest news and information from the NYC finals.

Eniram’s Dynamic Trimming Assistant (DTA) including the Eniram Vessel Platform (EVP) system for collecting real time data from the vessel had been installed aboard the container vessel Santa Catarina in 2011 to optimize vessel trim. The key system that produced results was Eniram’s Propulsion Power Decomposition (PPD) technology. No other major operations were done at the installation of the twisted fin, which meant that the change in performance was undoubtedly attributed to the twisted fin. The PPD model allows us to eliminate the impact of variable environmental conditions such as wind, sea state, trim and squat (called the dynamic sea margin) and create a hydrodynamic model of the vessel to simulate the impact to ensure a more accurate performance comparison in the before and after installation scenario.Santa CatarinaWe measured Santa Catarina in both laden and ballast conditions, divided the speed-power curves before and after the BTF installation and compared those to different speed areas. In laden conditions, there was no visible change under 15 knots. From 15 to 18 knots, there was a 1-3 % impact and above 18 knots, there was a 4-7% impact. The vessel’s average median operational speed being 19.4 knots. zoom In early 2013, global container operator Hamburg Süd, which operates a fleet of more than 105 vessels with a capacity of over 454,000 TEUs, replaced the pre-swirl stators originally installed on its Santa class vessels with the new Becker Marine Systems’ Twisted Fin (BTF), a further development of the Becker Mewis Duct.Pekka Autere, Lead Analyst at Eniram explains in the following text how the validity of the container vessel Santa Catarina’s new propulsion system has been alayzed with the use the high frequency data collected from the vessel. “Model tank tests of the BTF had indicated a favourable effect on the fleet, and in the case of Hamburg Süd’s Santa Catarina, since we already had existing data collected from the ship for two years previous, in the flash of a few minutes, we were easily able to select operational data from three months previous to the twisted fin installation as well as three months afterward to carry out our propulsion efficiency analysis. Additionally, in order to analyze the vessel’s performance in similar conditions, periods in laden (draft more than 11 meters) and ballast (draft below 10 meters) were chosen for comparison. The EVP system interfaces with a vessel’s data from the bridge and associated automated systems and measures real-time vessel performance and fuel consumption. In this case, it was important to see the results of improved efficiency of the propeller by optimizing distribution of water to the propeller. Thanks to Eniram’s combined DTA and PPD technology and real-time sea condition data-collecting, we were able to confirm the original theoretical calculations worked. Our systems not only help continuously automate and streamline how ship efficiencies are measured but our systems also remove the possibility of human error when collecting data, saving operators time and money while providing complete clarity of a ship’s performance at sea.

Washington: Pakistan Prime Minister Imran Khan arrived here on his maiden trip to the US during which he will hold talks with Donald Trump and reboot bilateral ties that were hit after the US president publicly criticised Islamabad, cancelled military aid and asked it to do more to fight terrorism.Khan, 66, is scheduled to meet President Trump at the White House on Monday during which the American leadership is likely to press him to take “decisive and irreversible” actions against terrorist and militant groups operating from Pakistani soil and facilitate peace talks with the Taliban. Also Read – US blacklists 28 Chinese entities over abuses in XinjiangThe cricketer-turned-politician arrived here on Saturday afternoon aboard a commercial Qatar Airways flight and is staying at the official residence of the Pakistani Ambassador to the US, Asad Majeed Khan.He was welcomed at the airport by his foreign minister Shah Mehmood Qureshi. A large number of Pakistani Americans also welcomed him.Nawaz Sharif was the last Pakistani prime minister to visit the US on an official trip in October 2015.During his three-day visit, Khan, in addition to his meeting with Trump, is also scheduled to meet IMF acting chief David Lipton and World Bank President David Malpass. Secretary of State Mike Pompeo will call on him on Tuesday. Also Read – Want to bring back US forces engaged in endless wars: TrumpTrump, in addition to a one-on-one meeting in the Oval Office, will host the visiting delegation over a working lunch at the White House on Monday. Khan is also scheduled to meet lawmakers at the US Capitol Hill.The relations between Pakistan and the US have remained tense during Trump’s tenure. The US president has publicly said that Pakistan has given us “nothing but lies and deceit” and also suspended security and other assistance for backing terror groups. Prime Minister Khan is accompanied by Army chief Gen. Qamar Javed Bajwa and spy agency ISI chief Lt. Gen. Faiz Hameed.Diplomatic sources in Islamabad earlier said that issues like the Afghan peace process, Pakistan government’s action against terrorism and terror financing and restoration of military aid to Pakistan would be the highlights of the trip.Khan’s visit comes at a time when talks between the US and Afghan Taliban are thought to have entered a decisive phase.Pakistan’s efforts have been appreciated for facilitating peace talks with the Taliban. Actions like launching of cases of terror financing against Hafiz Saeed, head of the Jamaat ud Dawa are signals aimed at addressing concerns by India and the US.Khan is also scheduled to address a gathering of Pakistani Americans in downtown Washington DC on July 21 and speak at the US Institute of Peace think-tank on July 23.Before becoming the prime minister, Khan used to visit the US regularly and has a sizeable support base among the Pakistani diaspora.Meanwhile, hours before Khan’s arrival, Pakistan hired the services of lobbying firm Holland & Knight. The memorandum of understanding on this was signed between former Republican Congressman Tom Reynolds and Pakistani Ambassador Majeed Khan.Reynolds will lead a team comprising other former members of Congress, former senior Administration officials, Capitol Hill veterans and other professional experts to lobby in the US on behalf of the Government of Pakistan. The Embassy had no lobbyist during the past six years.Khan’s visit to the US is also marked by protests by several ethnic and religious minorities of Pakistan, including Baloch, Sindhis and Mohajirs.The Baloch groups Saturday started a mobile billboard campaign in America’s national capital urging President Trump to help end “enforced disappearances in Pakistan.A bipartisan group of 10 influential American lawmakers asked President Trump to raise the issue of human rights abuses in Pakistan’s Sindh province in his meeting with Khan.Protests have been planned in front of the White House and Capitol Hill Arena by these groups over the next few days.
Ontario’s education system is getting a failing grade when it comes to math. Students’ scores in the subject are dropping, raising concerns among educators, and as students complete another round of standardized EQAO testing this week, some people are calling for a review of the current math curriculum. This week and next a variety of subjects will be evaluated, including math. While it can be stressful, students at St. Martin of Tours in Stoney Creek say they are well prepared.“Since the beginning of the year he told us there’s going to be an EQAO test at the end of the year. We all got practice booklets and we’ve been practicing every day,” said one student. “I felt more confident because we practiced it at the beginning of year instead of like in grade three we did it closer to the end so we didn’t have much time to practice,” said another.While students at this school have seen improvement in their math grades, it’s not the norm. Across the province and the country, scores are on the steady decline.Results from the most recent EQAO testing are not good for the Hamilton-Wentworth area. For the Catholic District School Board, 54% of its grade six students performed at or above the provincial average. For the Public District School Board it was lower, with less than half meeting or exceeding the provincial average.Researchers studying the drop in math scores point to a lack of practice and teachers saddled with too many subjects.“We need to move towards the hiring of teachers who have some degree of subject specialty who are keen and interested in teaching those subjects and who have the expertise to provide the best instruction,” says Joe Engemann, associate professor at Brock University. One retired teacher says scores are not adding up because the basics are being skipped over. She’s even petitioning for a review of the current curriculum. “Teachers don’t have resources. They need textbooks which are very inquiry based, so when teachers try to teach the basics, they go to the computer for materials and that’s not the best way,” says Teresa Murray.Results of the EQAO tests will be released in the fall.
“At no time in the past 20 years in dealing with this growing catastrophe has there been such a sense of collective resolve and collective possibility,” the Secretary-General stressed in a statement released at UN Headquarters in New York. “I believe this year will go down in history as the year we turned the tide.” In order to galvanize global awareness and “build a response that matches the challenge,” the Secretary-General pledged his personal commitment to the fight against AIDS and called for “every sector of society to play its full part” in the battle. Mr Annan said the upcoming General Assembly special session on HIV/AIDS “will be a test for all of us who call ourselves the international community.” He expressed confidence that by the time the session opens later this month, there would be “widespread” support for his proposed Global AIDS and Health Fund, which is open to contributions from both governments and private donors.In a related development, on Saturday the Secretary-General hailed the annual AIDS Memorial Quilt March in Washington, D.C. as a “fine example of the kind of response we need across the world in facing HIV/AIDS.”In a message to the event, Mr. Annan underscored the devastating toll taken by the pandemic. “It is as though the population of five cities the size of Washington, D.C. had been wiped out in the space of a single year,” he said.Mr. Annan said the message of the AIDS Memorial Quilt March must reach delegates attending the special session. “It is essential that they hear people speak up about the virus and demand decisive action against it,” he said.
“We have received alarming information that six indigenous peasants were killed and at least 30 injured,” a spokesperson for the Office of the UN High Commissioner for Human Rights (OHCHR), Rupert Colville, told reporters in Geneva. Seven soldiers are also reported to have been injured in the incident, which took place yesterday in the Department of Totonicapan. According to reports, the day started with a large number of indigenous people putting up several roadblocks protesting against the increase of electrical tariffs and provision of other basic services. Mr. Colville noted that there have been conflicting reports about the location in which the incident occurred. “Details remain unclear and our office in Guatemala is shortly sending two teams of human rights observers – one to Sololá Department and one to Totonicapan – to verify the facts and follow up on the incidents,” he said. The UN High Commissioner for Human Rights, Navi Pillay, visited Totonicapan during her mission to Guatemala in March, during which she met with traditional indigenous authorities to discuss a range of human rights concerns. During her visit, Ms. Pillay had noted that although indigenous peoples constitute the majority of the population in the country, they continue to be subject to exclusion and denial of their human rights. Guatemala was one of the first signatories of the UN Declaration on the Rights of Indigenous Peoples, which underscores that indigenous peoples have the right to participate in decision-making in matters which would affect their rights.
Stan Van Gundy is jobless.Whether center Dwight Howard asked for it or not, Stan Van Gundy is out as coach of the Orlando Magic — and general manager Otis Smith, too.Those two were at the helm of one of the franchise’s most successful eras, an era that in recent years has been marred by a tumultuous relationship between Van Gundy and Howard, its perennial all-star center. In fact, the relationship reached a peculiar stage when, prior to the playoffs, Van Gundy claimed, without prompting, that Howard had requested to the team’s hiearchy that Van Gundy be fired.Howard denied doing so, but soon after was sidelined with back troubles. Orlando went on to lose to Philadelphia in the first round. Turns out, that was Van Gundy’s and Smith’s final competition with the Magic.“It’s time for a new leadership and a new approach,” Magic CEO Alex Martins said at a news conference to discuss the moves. “We simply came to the decision that we were not on the right track.”Martins added: “At no time during that time did Dwight ask me to have Stan fired.”No replacements have been named, but Martins said the hope is to have a new general manager in place by the NBA Draft in late June.There has been much speculation about Howard. He vacillated much of the season on whether he would accept a trade. The latest is that he does not want to return a Orlando.
Manchester United duo of Nemanja Matic and Juan Mata are confident their side can still mount a serious title challenge despite a poor start to the new season.The Red Devils beat Burnley to end a run of successive defeats and currently six points behind leaders Liverpool after four games.Asked whether United can afford any further slip-ups considering the gap, Matic said: “Of course, but they (United’s rivals) also have to win all games, and I think that’s impossible.“Someone needs to lose to drop the points and it’s still too early to say something.“We will see in March where we are because in March you can see who is fighting for the title, who is not, who is fighting to be in the top 4. It is still too early.Vidic: “Ronaldo is the most professional footballer I’ve seen” Andrew Smyth – September 14, 2019 Nemanja Vidic opened up on how a 21-year-old Cristiano Ronaldo’s professionalism left him stunned at Manchester United.“We have to start to win the games and I think we played well, like we played first half against Spurs, I think we did well.Meanwhile, Juan Mata told the club’s official website: “On a personal level, the afternoon didn’t start so well for me when I found out I wouldn’t be involved in the game.“But two things helped me to feel better about myself – the result and the atmosphere from our fans in the stands.“The passion, spirit, intensity, and energy that comes from the fans is the engine that drives football.“The club is special for a lot of reasons, and undoubtedly one of them is all of you out there. You struggle along with us when we lose and celebrate with us when we win, just like yesterday.”
Facebook Twitter Google+LinkedInPinterestWhatsApp Facebook Twitter Google+LinkedInPinterestWhatsApp#Jamaica, October 27, 2017 – Kingston – The Universal Service Fund (USF) handed over four laptop computers to the children of persons affected by breast cancer, during its Positively Pink Midday Mingle on October 25 in observance of Breast Cancer Awareness Month.The USF-hosted event, which was held at the Petroleum Corporation of Jamaica (PCJ) Auditorium, Trafalgar Road in Kingston, featured presentations by Harmony Health Clinic and Medical Spa Physician, Dr. Sandra Allen-Knight; Officers and Board members of the USF, and others who shared their personal stories of breast cancer. Several breast cancer survivors were also presented with gift vouchers for spa treatment at the Eden Gardens Resort and Spa in Kingston.Minister of Science, Energy and Technology, Dr. the Hon. Andrew Wheatley, who brought greetings at the function, hailed the initiative and stressed the importance of family support for persons battling breast cancer.“In the family structure with husband, wife and children, when the woman is diagnosed with breast cancer and may have to remove her breast, the whole family must support that woman. I am pleased to see that as a society we are maturing and accepting that this is part of the process, and we are more supportive of women affected by this terrible disease,” he said.Breast Cancer Awareness Month is observed annually in October internationally in an effort to raise awareness and increase education on early detection, education and treatment of the disease. It is the most common cancer affecting women. According to a World Health Organization (WHO) Global Health Estimates, more than 508,000 women died from the disease in 2011.Women most at risk are over the age of 50 with a family history of breast cancer; have had their first child after age 30; have never had children; or are obese, that is, weighing 40 per cent more than their ideal body weight.Early detection is the best defence. Women are encouraged to do a breast self-examination every month, and have a clinical examination by a physician; and women 40 years and older should do a mammogram at least once a year. Men between 60 and 70 years of age are at increased risk of developing breast cancer.A mammogram is still the number-one screening tool for early detection of breast cancer. It is able to detect lumps two years before they can be felt and has the capacity to detect other abnormalities that indicate the presence of cancer.Additionally, a healthy plant-based diet with limited intake of processed foods and alcohol, and a minimum of 30 minutes’ exercise daily are some simple measures that can be adopted to lower the risk of developing cancer.

Ryan adds in a separate memo: “Although it has been a difficult decision to make, I have concluded that the closing of the sale will be the logical time to pursue other career options that have emerged in recent months and explore how best to put my business interests to work in a new arena.”I will remain in my roles at Politico and Allbritton Communications Company until my work in closing the television sale is complete. This gradual transition will allow Robert Allbritton to think about his goals for the company and his options for my successor at Poltico.” Frederick J. Ryan Jr. is leaving Politico and parent company, Allbritton Communications, later this year, he announced late Sunday night.Ryan (pictured), CEO and president of Politico and COO and president of Allbritton, will leave when the sale of the company’s television stations is completed.The sale—a $985 million deal announced in July, and expected to close by year’s end—will reportedly allow Allbritton chairman and CEO Robert Allbritton to increase the company’s investments in digital media, like Politico. The first hint of the new strategy came earlier this month as Politico purchased city-centric news startup Capital New York for an undisclosed sum.”This is a big moment in the life of our publication,” Politico’s executive team commented in an internal memo regarding Ryan’s announcement. “It is one we have known is coming for some time, and it comes at a moment when we are well-positioned to begin a new chapter at Politico.”
In this photograph taken on March 27, 2018, Myanmar fighters Than Zaw Htay (L) and Tun Tun (R) battle during a ground-breaking Lethwei competition marking Armed Forces Day in the town of Maungdaw in Rakhine state. Photo : AFPA boxing-fan tycoon, a venerated monk and the army lured some of Myanmar’s top fighters to Rakhine state this week in an attempt to show normality is returning after a military crackdown drove 700,000 Rohingya into exile.The deep cuts and brutal knockouts of ‘Lethwei’ — Myanmar’s bare-knuckle traditional boxing — made a debut in Maungdaw, a town with a history of violence against Rohingya Muslims.For seven long months, Maungdaw in northern Rakhine has been under curfew as the military systematically forced Rohingya Muslims over the border into Bangladesh.Ethnic Rakhine stand accused of colluding with the security forces in mass killings, widespread rape and the burning down of Rohingya villages — actions the UN has labelled as ethnic cleansing.Myanmar vehemently rebuts the allegation, saying it was forced to act to fight off Rohingya militants who launched raids on police posts on August 25 last year.Authorities — aided by rich businessmen — have piled in with redevelopment cash and say the refugees are welcome back, insisting that the communal scars are healing.Yet only 556 Rohingya have been ‘verified’ for repatriation so far — and none have returned.Soe Tun Shein, a tycoon known for his love of Lethwei and his anti-Muslim views, stumped up the cash behind the Lethwei event — the first ever in Maungdaw — which organisers confirmed was given the green light by Senior General Min Aung Hlaing, who heads Myanmar’s army.”The army chief is supporting this and instructed his officers here to make sure the competition was a success,” Myanmar Lethwei Federation Chairman Thein Aung, 71, told AFP.”I believe that (Lethwei) encourages people to love the country and to develop our traditional arts,” he added.But critics decried the event as a PR move by authorities desperate to gloss over crimes against the Rohingya.”It is another squalid stunt in a series of propaganda shows crudely fashioned to delude the people of Myanmar and the world,” said Yangon-based independent analyst David Mathieson.”It is military soft power that will not assuage the fears of people left in northern Rakhine.”‘No trust anymore’While the focus has been on their enmity with the Rohingya, many Rakhine are also deeply distrustful of the central government and military, long-dominated by the ethnic ‘Bamar’.Rakhine nationalist sentiment boiled over in the nearby ancient temple city of Mrauk U in January, sparking riots that ended with police shooting dead seven protesters.The incident made the task of winning back the hearts and minds of ethnic Rakhine all the more pressing to authorities.Some of the top names in Lethwei travelled to Rakhine to take part in the bout, held in a new stadium — and were even treated to a sightseeing trip to the Bangladesh border.”I agreed to fight because I did not know about the problems here and I have never been here before,” says 28-year-old fighter Saw Ba Oo from eastern Karen State, who drew against his opponent in the climactic finale and took home $2,600 in prize money.But tension and insecurity pervaded the atmosphere, even finding their way into the boxing ring.Local Buddhist monk Manisara, a community leader who hosted the visiting boxers at his monastery and served as announcer for the fights, heaped praise on the military for defending his flock.”When we are in trouble, the Tatmadaw (armed forces) are the only ones we can rely on,” he says. “Without them, we live in danger.”The Lethwei tournament did offer what some might see as a flicker of hope for the divided town.A handful of Rohingya children cheered alongside ethnic Rakhine youngsters with whom they play football on the adjacent sports field most evenings.The communities, who live side-by-side across the small town, are forced out of necessity to have some level of interaction on a daily basis even if, for now, their relationship is riven by suspicion and fear.”We used to visit each other’s houses,” said Lethwei fan Myo Thandar Aye, 25.”But we can never go back to the relationship we had before. We don’t trust each other.”

A graphene photodetector with gold contacts in the form of a snowflake-like fractal pattern has a higher optical absorption and an order-of-magnitude increase in photovoltage, as compared to graphene photodetectors that have contacts with plain edges. Credit: Fang et al. ©2016 American Chemical Society © 2017 Phys.org The researchers explained that these characteristics can be directly attributed to the fractal pattern. (Phys.org)—Researchers have found that a snowflake-like fractal design, in which the same pattern repeats at smaller and smaller scales, can increase graphene’s inherently low optical absorption. The results lead to graphene photodetectors with an order-of-magnitude increase in photovoltage, along with ultrafast light detection and other advantages. “Our proposed fractal metasurface has the unique ability of supporting plasmonic resonances (free electron oscillations) over a wide spectral range in a polarization-insensitive way due to its complex and highly hexagonally symmetric geometry,” Kildishev said. “Previously reported plasmonic-enhanced graphene photodetectors use simpler narrowband and polarization-sensitive structures, and therefore the enhancement is also narrowband and polarization-sensitive.”As previous research has shown, the reason that a fractal pattern can improve optical absorption is that the fractal metasurface creates additional resonances, with the amount of resonance increasing as the number of fractal levels increases. In addition, the researchers here found that the fractal metasurface confines and enhances the electric field of the light that hits the surface. This ultimately leads to a higher photovoltage generated in the graphene photodetector.As Kildishev explained in more detail, there are two major mechanisms of inducing photovoltage in a graphene-based photodetector: the photovoltaic effect and the photothermoelectric effect. The photovoltaic effect uses the built-in electric field induced by differently doped regions in graphene to separate the optically excited electron hole pairs in graphene. The photothermoelectric effect drives the free electrons in graphene across regions with different thermoelectric powers (Seebeck coefficients), given a temperature gradient in between the two regions. The fractal metasurface enhances both effects in graphene photodetectors by increasing the electric field intensity and by heating via incident light in highly confined spaces.”The fractal metasurface enhances the photovoltage by making use of plasmonic resonance—free electron oscillations in gold under the excitation of light,” Kildishev said. “This then confines the electromagnetic energy to ultra-small volumes, generating excessive electron-hole pairs in graphene which are then separated by the photovoltaic effect. The incident light also heats up the plasmonic structure to create a large temperature gradient across the metal/graphene interface, giving rise to a stronger photothermoelectric response.”In the future, the researchers plan to explore the potential applications of graphene photodetectors, which could extend beyond photodetection to photoharvesting, with applications such as solar cells and optical heating. Technologies that require a fast response could also experience significant improvements due to the graphene photodetector’s fast operation speed.”One great attribute of the graphene photovoltaic/photothermoelectric detector is that it reacts to light at an extremely fast rate, thanks to the ultrafast electron moving speed (photovoltaic effect) and the ultrashort time the electrons need to give away heat (photothermoelectric effect) in graphene,” Wang said. “Such response speed is unparalleled by other photodetection materials. “Plasmonic enhancement has been known to sacrifice the ultrafast response speed to a minor extent. Therefore, plasmonic-enhanced graphene photodetectors are promising for all-optical modulator readout and other applications where response speed is key. Moreover, graphene has zero (or tunable) bandgap and uniform optical absorption in the entire electromagnetic spectrum. Therefore, graphene photodetectors can in principle be used to detect light of any frequency with identical sensitivity, which again is unparalleled by other detectors made of other photodetection materials.” Developing graphene microwave photodetector Explore further This document is subject to copyright.

The researchers, from Purdue University in Indiana, include graduate students Jieran Fang and Di Wang, who were guided by professors Alex Kildishev, Alexandra Boltasseva, and Vlad Shalaev, along with their collaborators from the group of Professor Yong P. Chen. The team has published a paper on the new graphene photodetector fractal design in a recent issue of Nano Letters.Photodetectors are devices that detect light by converting photons into an electric current. They have a wide variety of applications, including in X-ray telescopes, wireless mice, TV remote controls, robotic sensors, and video cameras. Current photodetectors are often made of silicon, germanium, or other common semiconductors, but recently researchers have been investigating the possibility of making photodetectors out of graphene.Although graphene has many promising optical and electrical properties, such as uniform, ultra-broadband optical absorption, along with ultra-fast electron speed, the fact that it is only a single atom thick gives it an intrinsically low optical absorption, which is its major drawback for use in photodetectors. To address graphene’s low optical absorption, the Purdue researchers designed a graphene photodetector with gold contacts in the form of a snowflake-like fractal metasurface. They demonstrated that the fractal pattern does a better job of collecting photons across a wide range of frequencies compared to a plain gold-graphene edge, enabling the new design to generate 10 times more photovoltage.The new graphene photodetector has several other advantages, such as that it is sensitive to light of any polarization angle, which is in contrast to nearly all other plasmonic-enhanced graphene photodetectors in which the sensitivity is polarization-dependent. The new graphene photodetector is also broadband, enhancing light detection across the entire visible spectrum. In addition, due to graphene’s inherently fast electron speed, the new photodetector can detect light very quickly.”In this work, we have solved a vital problem of enhancing the intrinsically low sensitivity in graphene photodetectors over a wide spectral range and in a polarization-insensitive manner, using an intelligent self-similar design of a plasmonic fractal metasurface,” Wang told Phys.org. “To our knowledge, these two attributes were not achieved in previously reported plasmonic-enhanced graphene photodetectors.” Journal information: Nano Letters More information: Jieran Fang et al. “Enhanced Graphene Photodetector with Fractal Metasurface.” Nano Letters.

Congratulations to the Arenal Expeditionary Team for their recent ascent of Mount Chirripó, Costa Rica’s highest peak. Remarkably, the combined ages of the climbers exceeds 200 years. Sue Jones, a member of the 14 Club (people who have climbed peaks more than 14,000 feet high) had undergone a hip joint replacement less than a year before. After months of conditioning, David Fountaine, Jim Aoki and Sue felt ready to meet the challenge of Chirripó.Mount Chirripó can be very unforgiving. Summit temperatures have been recorded at -27 degrees Celcius with wind velocities exceeding 75 mph. At 10,000 feet, oxygen levels start dropping, increasing the effort of every step. Unseasonable warm spells had left the lower slopes wet with slippery foot-grabbing mud, which imposed demands on physical reserves earlier than usual.Leaving base camp before daylight, the team climbed for 9.5 grueling hours to reach the summit camp, from which final ascent started the following day.A rustic windbreak with bunk beds and a supply of icy water looks inviting to cold, exhausted climbers who must start their trek to the top at 2:30 a.m. in order to return to base camp before dark. A thick layer of frost covered the ground as they started out.The return proved equally challenging, as the mucky lower slopes caused many slips and falls when boots lost traction. The Golden Rule of climbers is a quote from Sir Isaac Newton: “Gravity always wins.” His observation was proven many times during the difficult descent. After long hot baths and much celebrating, the triumphant trio dosed up on Aleve and sacked out at 7:30 p.m.It took five days for the stiffness and pain to subside, during which no one walked on anything but flat ground. Already there’s talk of another climb in March, with other folks who have added Chirripó to their bucket lists. The unanimous recommendation from the Arenal Expeditionary Team: Hire pack mules to carry your stuff, including a small bottle of oxygen. It might prove helpful.Final Note: the feria held on the second and fourth Sundays of the month at Cinco Esquinas is attracting more vendors and more buyers looking for anything from fresh organic produce to clothing, plants, massage oils and beauty products, goat milk cheese – you name it. Each session brings additional vendors with different items for sale.Half-sized hamburgers (called “sliders”) are available hot-off-the-grill for cheap and are a real favorite with shoppers – some of whom arrive on horseback! The feria goes from 9 a.m.-2 p.m. and is a great way to meet folks from around the Lake Arenal area.–William & Jean Priestjean_pri@msn.com Facebook Comments No related posts.
