Five things to know about WikiLeaks

first_imgIn this file photo taken on May 19, 2017 Wikileaks founder Julian Assange speaks from a balcony at the Embassy of Ecuador in London. British police have arrested WikiLeaks founder Julian Assange at Ecuador`s embassy in London after his asylum was withdrawn, the police said in a statement on April 11, 2019. AFPWikiLeaks has been making headlines for more than a decade by releasing millions of classified documents, embarrassing governments while also raising fears that its activities may have put lives in danger.Controversy also swirls around its founder Julian Assange, who was arrested on Thursday after being holed up in the Ecuadoran embassy in London for nearly seven years.Here are five things to know about WikiLeaks.- 10 million leaks -WikiLeaks was founded in 2006 by Australian-born Assange, who said it would use encryption and a censorship-proof website to publish secret information and protect sources.It first caught the world’s attention in 2007 with the release of manuals for US prison guards at Guantanamo Bay.But it really hit its stride in 2010 when it worked with The New York Times, The Guardian, Der Spiegel, Le Monde and El Pais to publish millions of classified diplomatic cables.It has published more than 10 million leaked documents and associated analyses, to the dismay of politicians, governments and corporations.- Controversy strikes -In its early days, WikiLeaks worked with dissidents worldwide to expose government secrets from the United States to Europe, China, Africa and the Middle East.But over time it has increasingly set its sights on the US. Assange has denied claims that it might be working with Russia.WikiLeaks raised a storm in July 2016 by releasing emails showing US Democratic Party officials favouring Hillary Clinton over left-winger Bernie Sanders in the presidential primary elections, forcing high-ranking party members to resign.WikiLeaks was also accused of revealing the identity of a gay man in ultra-conservative Saudi Arabia. Again, the group denied the accusation.- Arrest warrant -The worst scandals to affect WikiLeaks have been those involving Assange.Hailed as a hero by supporters and reviled as a manipulator by critics, the white-haired Australian was holed up in the Ecuadoran embassy in London since 2012, when he was facing rape allegations in Sweden.Swedish prosecutors dropped their investigation in 2017 but Assange remained in the embassy, fearing the US would extradite him for revealing state secrets.- Snowden and Manning -The mass exposure in 2010 of US diplomatic cables, which embarrassed governments worldwide, would not have been possible had it not been for US soldier Chelsea Manning, who handed WikiLeaks 700,000 classified documents.She was given a 35-year prison sentence in 2013 and served more than three years before being freed in 2017.In March 2019 she was jailed again for refusing to testify in a grand jury investigation targeting WikiLeaks.Former US intelligence contractor Edward Snowden has also received WikiLeaks’s backing, though he did not use the group’s site to publish his leaks about the National Security Agency.Assange recommended he quickly flee to Moscow to evade prosecution in the US — advice he heeded.- In the movies -Two major films have been made about WikiLeaks — “The Fifth Estate” (2013) and “Risk”, a documentary that was screened at the Cannes film festival in 2016.Assange meanwhile guest-starred as himself in an episode of “The Simpsons” in 2012, recording his lines over the phone from the Ecuadoran embassy.last_img

Driven by Streaming Global RecordedMusic Revenues Soar to 191 Billion

first_img Popular on Variety The global recorded music market grew by 9.7% in 2018 — its fourth consecutive year of growth — to $19.1 billion, according the latest annual report from the International Federation of the Phonographic Industry (IFPI).Streaming revenue grew by 34.0% and accounted for almost half (47%) of global revenue, powered by a 32.9% increase in paid subscription streaming, according to the report. There were 255 million users of paid streaming services at the end of 2018, with paid streaming accounting for 37% of total recorded music revenue. Growth in streaming more than offset a 10.1% decline in physical revenue and a 21.2% decline in download revenue.Streaming in North America was up by 14%, though that was down from 2017’s 17.1%.Looking at individual markets, for the fourth consecutive year, Latin America was the fastest-growing region (+16.8%) with Brazil (+15.4%) and Mexico (+14.7%) growing strongly. The Asia and Australasia region (+11.7%) grew to become the second-largest region for combined physical and digital revenue, with especially strong growth in South Korea (+17.9%). Drake Tops IFPI’s 2018 Best-Selling Artist List Related The top 10 markets are, in order, the U.S., Japan, the U.K., Germany, France, South Korea, China, Australia, Canada and Brazil.The IFPI previously named Drake as the biggest recording artist of 2018, while “The Greatest Showman” was the top-selling album and Camila Cabello’s “Havana” was the biggest global single of the year.“Last year represented the fourth consecutive year of growth, driven by great music from incredible artists in partnership with talented, passionate people in record companies around the world,” said Frances Moore, chief executive of IFPI.“Record companies continue their investment in artists, people and innovation both in established markets and developing regions that are increasingly benefitting from being part of today’s global music landscape.“As music markets continue to develop and evolve, it is imperative that the appropriate legal and business infrastructure is in place to ensure that music is fairly valued, and that the revenues are returned to rights holders to support the next cycle of development.” ×Actors Reveal Their Favorite Disney PrincessesSeveral actors, like Daisy Ridley, Awkwafina, Jeff Goldblum and Gina Rodriguez, reveal their favorite Disney princesses.

Observing matterwave diffraction from a periodic array of half planes

first_img “Our experiment is based on the wave–particle duality, which is a basic concept in quantum mechanics,” Wieland Schöllkopf, one of the researchers who carried out the study, told Phys.org. “The idea that microscopic particles such as electrons, neutrons, atoms or even molecules exhibit wave-like behavior dates back to the 1920s, when Louis de Broglie introduced the particle wavelength, which today is referred to as the ‘de Broglie wavelength.'” Since de Broglie first developed his theory, researchers have carried out numerous experiments observing diffraction and interference, two wave phenomena that cannot be explained in a particle picture. The main aim of the study carried out by Schöllkopf and his colleagues was to investigate novel matter-wave diffraction methods that allow for coherent manipulation of atomic and molecular beams. “We observed diffraction of He atoms and D2 molecules scattering off from a grating structure,” Schöllkopf explained. “The latter is formed by a periodic array of polymer film structured on a gold-coated glass substrate. A variety of grating structures, all with identical period, but differing in the width of the polymer stripes, were made at UNIST in Ulsan, Korea. These gratings were used in the diffraction apparatus at the Fritz-Haber-Institut in Berlin, Germany.” The apparatus at the Fritz-Haber-Institut allowed the researchers to generate an intense beam of He or D2 with extremely narrow angular divergence. The generated beam is incident to the grating under grazing conditions, hence, the particles’ velocity component perpendicular to the grating surface is very small. “In previous experiments carried out at our lab, we have observed coherent reflection and diffraction from a grating structure under grazing incidence conditions,” Schöllkopf said. “This was attributed to ‘quantum reflection,’ which is a reflection mechanism different from classical reflection.” In classical reflection, as atoms or molecules approach a surface, they are affected by the atom-surface van der Waals force. This force leads to an acceleration towards the surface, with the particle ultimately bouncing off from the surface. On the other hand, in quantum reflection, the atoms or molecules already bounce back from the region in space dominated by the van der Waals force. Researchers at Ulsan National Institute of Science and Technology (UNIST), in Korea, and Fritz-Haber-Institut der Max-Planck-Gesellschaft, in Germany, have recently conducted a study investigating matter-wave diffraction from a periodic array of half planes. Their paper, published on Physical Review Letters (PRL), reports on the reflection and diffraction of He and D2 beams from square-wave gratings of a 400−μm period and strip widths ranging from 10 to 200 μm at grazing-incidence conditions.

Fresnel Diffraction Mirror for an Atomic Wave, Physical Review Letters (2005). DOI: 10.1103/PhysRevLett.94.013203 A third reflection mechanism, which differs from classical and quantum reflection, is based on the diffraction of the de Broglie waves of atoms or molecules from the edges of half planes, which are very narrow ridges on a surface. This mechanism, first observed in Japan by Prof. Shimizu and his colleagues, is now referred to as “Fresnel diffraction mirror” due to its analogy with the edge diffraction of light waves in optics. In their study, Schöllkopf and his colleagues observed fully resolved matter-wave diffraction patterns, including specular reflection and diffracted beams up to the second diffraction order. They also found that as strip width decreased, diffraction efficiencies transformed from the known regime of quantum reflection to the regime of edge diffraction. “In our experiment, we observed the transition from quantum reflection for relatively large widths of the grating stripes to the regime at small stripe widths where edge diffraction dominates,” Schöllkopf said. “Furthermore, in addition to the specular (mirror-like) reflection seen previously, we observed intense grating diffraction beams up to second order.”The experimental findings collected by the researchers confirm a previously developed single-parameter model, which is commonly used to describe a variety of phenomena, including quantum billiards, scattering of radio waves in urban areas and the reflection of matter waves from microstructures. Moreover, their observations suggest that neither classical nor quantum reflection mechanisms are essential for the reflective diffraction of matter waves from a structured solid, as this can result exclusively from half-plane edge diffraction. “Our observations allowed us to make a quantitative analysis of the reflection and diffraction efficiencies,” Bum Suk Zhao from UNIST, the principle investigator of the study, told Phys.org. “This, in turn, allowed for an experimental test of the Bogomolny-Schmit model of half-plane array diffraction. According to this model description the phenomenon is fully scalable with respect to the wavelength and the dimensions of the half-plane array. As a result, for a given incidence angle, the scattering of atomic matter waves of 1 nm de Broglie wavelength from a 4-μm-period array of parallel half planes shows identical diffraction effects as, e.g., the scattering of 1-cm-wavelength radio waves off buildings separated by 40 m.” The study conducted by Schöllkopf, Zhao and their colleagues provides a clear confirmation of the Bogomolny-Schmit model. In the future, their findings could also be used as a test bench for models of quantum reflection from microstructured surfaces that need to account for half-plane edge diffraction. In their next studies, the researchers plan to apply half-plane array diffraction to the investigation of weakly bound molecules, such as the He dimer and trimer.”Due to their extremely small binding energies, these di- and triatomic helium molecules are not amenable to many experimental tools,” Bum Suk Zhao explained. “For instance, classical scattering of He2 from a solid surface will inevitably lead to break-up. To overcome these limitations, more experimental techniques allowing for non-destructive manipulation of these species are needed. Half-plane array diffraction is a well suited method for this purpose.” ‘Meta-mirror’ reflects sound waves in any direction Journal information: Physical Review Letters “This counter-intuitive quantum effect of attractive forces, effectively resulting in recoil of the particle, can only be observed if the incident velocity in the direction perpendicular to the surface is very small,” Schöllkopf explained. “This is why, in our experiment, we can only observe quantum reflection at near grazing incidence conditions.” © 2019 Science X Network Citation: Observing matter-wave diffraction from a periodic array of half planes (2019, February 20) retrieved 18 August 2019 from https://phys.org/news/2019-02-matter-wave-diffraction-periodic-array-planes.html A photograph of the research team taken inside a lab at Fritz-Haber-Institute, in Berlin.

Mamata as PM is not an isolated comment by BJP Somen Mitra

first_imgKolkata: West Bengal Congress president Somen Mitra Monday said BJP president Dilip Ghosh’s comment that Mamata Banerjee has the best chance to become PM, is proof of “tacit understanding” between TMC and the BJP. “Dilip Ghosh’s statement that Mamata Banerjee has the best chance to become the first Bengali Prime Minister is not an isolated statement. It is a reflection of tacit understanding between both the parties in the state. We have been saying this for a long time but now the cat is out of the bag,” Mitra told reporters here. Also Read – Rain batters Kolkata, cripples normal life Ghosh had, however, on Sunday made a U-turn and said his remark the day earlier on Chief Minister Mamata Banerjee’s prime ministerial prospects was made in jest. Mitra termed Ghosh’s u-turn as a “lame excuse” and said that the people of the state very well understood the kind of “political setting” that exist between parties. Mitra claimed that by making the statement, Ghosh has virtually accepted that the BJP will not return to power in the 2019 Lok Sabha polls and might extend support to Mamata Banerjee in such a scenario. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killed Commenting on the general strike called by various Left trade unions on January 8 and 9, Mitra said TMC’s opposition to the strike call is another example of ‘TMC-BJP fixed match’ in the state. “Why is she opposed to the strike call in the state? It is not against the state government. It is a nationwide strike call against the policies of the Modi government. This only proves that the TMC and BJP are both on the same page regarding economic policies and TMC’s call to fight against BJP is nothing but a farce,” he said. As many as 10 central trade unions have called a nationwide general strike on January 8 and 9, against the “anti-people” policies of the Centre and have placed a charter of 12 demands before the Centre. The demands include minimum wage, universal social security, workers’ status and including pay and facilities for the scheme workers, against privatisation of public and government organisations. Leaders and activists of various parties including TMC, Union Muslim League and CPI(M) Monday joined Congress and vowed to fight against the communal politics of TMC and BJP in the state.last_img read more
