A court here on Monday started recording depositions of witnesses against five accused, including Shafat Ahmed, in a case filed for raping two private university girls in a Banani hotel.Judge of the Women and Children Repression Prevention Tribunal-2 M Safiul Azam recorded the testimony of the complainant of the case in camera in the presence of the counsels of both plaintiff and the defence, reports UNB.The tribunal also fixed October 31 for the next hearing in the case, said plaintiff’s lawyer Fahmida Akhter Rinki.After the deposition of the complainant, Shafat’s lawyer Mosharraf Hossain Kajal started cross-examining the witness which could not be completed today, she said.The five accused were produced before the court from jail during the proceedings.The two female private university students were raped at The Raintree Dhaka hotel at Banani in the city on March 28 last. One of the victims filed a case with Banani Police Station on May 6 over the incident.On June 8, police pressed charges against all the accused in the case.Of the accused, Shafat Ahmed, 26, and Nayem Ashraf, 30, were sued for raping the two female university students while Sadman Shafiq, 24, Shafat’s driver Billal, 26, and his unnamed bodyguard for abetting in the crime.The prime accused, Shafat Ahmed, is the son of Dildar Ahmed who owns top jewellery brand “Apan Jewellers” along with three of his brothers.
Hillary Clinton and Donald TrumpUS Democrats, licking their wounds from last year’s election debacle, will pick a new leader Saturday to take the fight to President Donald Trump and his Republicans.With opposition Democrats preparing for crucial 2018 midterm elections and the nation’s next presidential race on the distant 2020 horizon, nothing less than the future of the party is at stake.The race to chair the Democratic National Committee (DNC) features front-runners Tom Perez, a Hispanic-American and former secretary of labor under Barack Obama who is the establishment pick, and Keith Ellison, a black Muslim congressman from the party’s progressive wing who has left open the prospect of pushing to impeach Trump.The race is narrowing — one of the second-tier challengers, South Carolina Democratic Party chairman Jamie Harrison dropped out of the race Thursday and supported Perez — and culminates in a vote Saturday at a DNC meeting in Atlanta, Georgia.During a debate with several DNC candidates Wednesday night, Perez and Ellison expressed similar views about how they would run the party.They acknowledged that it needs to take a solid economic message to working-class and middle-class Americans, many of whom said during last year’s campaign that they felt abandoned by Democrats.Perez, 55, said Democrats need to “get back to basics” by making house calls in all 50 states and establishing a year-round organizing presence to remind American workers that the Democratic Party represents their values and interests.”When we lead with our message, our message of economic opportunity, that’s how we win,” he said during the debate broadcast on CNN.- Crisis of confidence -Perez also warned that Democrats must reform their party’s presidential primary system, which he said has created “a crisis of confidence” because of its lack of transparency.The current system includes the use of several hundred so-called “super-delegates” — DNC members, party grandees and lawmakers who can vote for whomever they choose in the primary, regardless of how citizens vote in the states.Ellison, 53, is the insurgent in the race, a supporter of liberal Bernie Sanders during the Democratic primaries who, like Perez, has pledged to reclaim the party’s reputation of standing for fair trade, jobs, infrastructure investment and the preservation of Social Security.”That’s what we do,” said Ellison, who was endorsed by Sanders. Trump “stole a Democratic message” by constantly reminding working-class and middle-class voters during the campaign that he was the candidate who listened to their concerns.Trump no doubt is watching the DNC race closely. Earlier this week he tweeted that Ellison’s bid is notable because “he was the one who predicted early that I would win!”Beyond Perez and Ellison, a dark horse has emerged: Pete Buttigieg, the charismatic 35-year-old mayor of South Bend, Indiana.He has earned support from former presidential candidate Martin O’Malley, former DNC chair Steve Grossman, and Vermont ex-governor Howard Dean, himself a onetime presidential candidate and DNC chair.”The wolf is through the gates and eating our sheep right now. We’ve got to take it to the real opposition, which is the Republicans,” Buttigieg said in the debate.The falsehoods peddled by the Trump White House must be “met with fact and outrage,” he added. But at the same time, the focus has to return to struggling Americans.”We’ve got to get back to talking to people and about people in terms of their everyday lives.”The three candidates pledged to remain neutral should sitting Democrats be challenged by more liberal candidates in the 2018 midterm elections in the Republican-controlled Congress.And they portrayed the Democrats as a party desperate for a reenergizing from the ground up.Grossman, one of the former DNC chairs, said Trump was far more adept than Hillary Clinton, the Democratic presidential candidate he defeated, at showing Americans that he could feel their pain.”He did, and she didn’t, and that was the difference,” Grossman told CBS radio earlier this month, as he said the new DNC chair will be tasked with bringing that message home to voters.Saturday’s winner needs a majority of the DNC’s 447 members. Roll Call newspaper reported a number of ballots would likely be needed for a candidate to emerge victorious.
By George Kevin Jordan, Special to the AFROIt’s time to dust off your goggles, pull out that snorkel and gather those fins, as D.C. gets ready for pool season. This past week, Mayor Muriel Bowser and the District rolled out the official pool season during a press event at Langdon Pool and Spray Park, 2680 Miles Avenue, N.E. In 2018, Langdon went through a $3 million renovation which made it the only place in D.C. with a combination of pool and spray park. Other features of Langdon include: a new pool and all new equipment, six lap lanes, ADA ramp and handrail into the pool, drinking fountain for people and their pets, and a splash pad area, with multiple spray features, according to the mayor’s office.Public pools are now open in the District on weekends and will be open on weekdays beginning June 17.(Courtesy Photo: dpr.dc.gov)“In D.C., we view our parks and pools and playgrounds and senior wellness centers not as a luxury, but as must haves – in every neighborhood, in every corner of the District,” said Mayor Bowser. Washington, D.C. celebrated being ranked the #1 park system in the country by The Trust for Public Land. The Trust’s survey found that 98 percent of District residents live within a 10 minute walk of a park.“The investments we’ve made have helped us achieve the #1 ranked park system in the nation, including a world-class system of indoor and outdoor pools for D.C, families to enjoy throughout the summer,” Bowser said.“We achieve this honor by investing more than $200 million to ensure that all residents have this great access. Coming into office we made another pledge that all of our fitness and recreational centers would be absolutely free for D.C. residents.”“So we recognize how important it is, especially in a growing city to have better access to places where they can have fun for free.”The mayor spoke of adding 1,000 new slots to eight sites around the city for kids, as well as other investments in the district’s summer camp programs. “When we’re talking about giving people a fair shot we want to make sure we have free things, as [often] as we can, including this pool,” Bowser said. “…we have affordable and [many] activities for families. When we do that we know that everybody has equal access to opportunity around our city.”The Department of Parks and Recreation (DPR) is expanding swim hours for 10 pool locations including: Anacostia, Francis, Langdon, Kenilworth, Oxon Run, Lincoln Capper, Happy Hollow, Harry Thomas, Upshur, and Banneker. those locations will open at 10 a.m. instead of 11 a.m.Pools will be open on a weekend-only schedule (Saturday and Sunday) through June 16. Starting Monday, June 17, all outdoor pools will operate on individual summer schedule. Spray Parks open Saturday, May 25 and operate daily, from 10 a.m. – 8:00 p.m., according to the mayor’s office.The DPR aquatic inventory includes 19 outdoor pools, 11 indoor pools, 23 spray parks and three children’s pools.For more information on the summer outdoor pool schedule, visit: dpr.dc.gov/page/outdoor-pools.
Laser interferometer gravitational wave detectors use laser light to measure the distances between mirrors. And light, being an electromagnetic (EM) field, is quantum in nature. EM fields contain quantum noise, fluctuations that make the beams less “sharp,” so to speak. Fluctuations mean that the physical parameters describing the beam are not fixed, but instead have built-in uncertainty or fuzziness, which limits the sensitivity of a gravitational wave detector.The researchers in this study, from several institutions in the U.S. and Australia,* seem to have found a solution to this problem: using “squeezed” light. When light is squeezed, the fluctuations of one parameter, such as the light wave’s amplitude, can be reduced at the expense of increased fluctuations of another parameter, such as its phase. The amplitude is a measure of the number of photons in the light beam, while the phase describes its location in time. Quantities corresponding to amplitude and phase are called quadratures, and quantum mechanics allows the uncertainty in one quadrature to be reduced as long as the uncertainty in the complementary quadrature increases.In this case, the scientists squeezed one quadrature of the light, decreasing its quantum noise. While the noise of the other quadrature is necessarily increased, it is a quadrature they don’t need to measure. By injecting the squeezed EM field in their prototype detector, the scientists were able to make it 44 percent more sensitive.“The significance of this work is that it forced us to confront and solve some of the practical challenges of squeezed state injection—and there are many,” said Massachusetts Institute of Technology physicist Nergis Mavalvala, the team’s leader. “We are now much better positioned to implement squeezing in the kilometer-scale detectors, and catch that elusive gravitational wave.” she added.Gravitational wave detectors work, in general, by interfering two laser beams that have traveled very long distances. The beams travel down two arms that form a 90 degree angle. While each arm is up to 4 kilometers in length, mirrors reflect the beams back and forth multiple times, effectively increasing the arm length to a few hundred kilometers. If a gravitational wave from deep space alters the length of each arm, the change to the laser interference pattern will be measurable.Existing gravitational wave detectors are so sensitive that they have already approached the quantum limit. They include the two LIGO (Laser Interferometry Gravitational Wave Observatory) facilities in Washington and Louisiana, both operated jointly by the Massachusetts Institute of Technology and the California Institute of Technology; and Europe’s largest gravitational wave detector, Virgo, located in Italy.The researchers say that the next generation of gravitational wave detectors, such as Advanced LIGO, the planned upgrade to both LIGO facilities, will boast some impressive improvements, but further advancements will have to rely on quantum techniques such as squeezing.Citation: K.

Pair of supermassive black holes discovered on a collision course Explore further A research collaboration has taken steps toward improving the sensitivity of gravitational wave detectors, devices designed to measure distance changes as minute as one-thousandth the diameter of a proton. Scientists hope these detectors can one day further verify Einstein’s theory of general relativity and even open a new window into the strange workings of the universe.

Gravitational waves, such as those emitted by extremely massive astronomical sources like neutron stars and black holes, can change the distance between two objects—even if that distance change is almost incomprehensibly small—by altering the shape of spacetime. Devices that can sense gravitational waves are among the most sensitive position meters ever built, but, right now, their abilities are inherently limited by quantum mechanics.
