Khaleda ZiaThe head of a pro-Awami League organisation has lodged a complaint of sedition charge against BNP chairperson Khaleda Zia with a Dhaka court on Wednesday.Bangabandhu Foundation executive chairman Mashiur Rahman allegedly that Khaleda had held a secret meeting with an official of Pakistani intelligence agency ISI in the United Kingdom.The court of chief metropolitan magistrate Abdullah Al Masud that received the complant in the morning is set to pass an order later in the day.In his complaint, Mashiur claimed that during her stay in London, Khaleda met ISI official Junaid at Taj Hotel on 18 and 19 July last.He alleged that the meeting was held to instigate anarchy in the country, and deteriorate the Bangladesh-India relation and take it towards war.He came to know about the meeting through different media reports and investigation conducted by Bangabandhu Foundation’s London unit, Mashiur said.Mashiur filed another sedition case against the BNP chief on 25 January which is still under trial.
The highly reactive hydroxyl radicals typically appear in fractions of a second prior to combining with volatile organic chemicals and other gases which act as a cleanser for the atmosphere. Scientists found unusually high levels and surge in hydroxyl radical levels, but without an accompanying increase in ozone levels around noon time. The scientific team found hydroxyl radicals levels some three to five times more than would be expected in current models of atmospheric chemistry. Altogether, for some inexplicable reason or known source of hydroxyl produced an astounding 28 parts per billion each hour concentration of the chemical.The net effect is that a not yet discovered process has occurred in the Pearl River Delta that is producing an extremely high level of hydroxyl radicals. The next step of the research is to test samples of the air from the Pearl River region to see if light-stimulated reactions produce similar high readings of hydroxyl radicals under lab conditions. Thus far, the scientists are impressed with their unusual findings, but are only able to speculate on the source coming from a combination of anthropogenic sources, biogenic sources and gases found in the air surrounding the delta.Source: Amplified Trace Gas Removal in the Troposhere; www.sciencemag.org/cgi/content/abstract/1164566 Chemists find important contributor to smog Credit: Wikipedia A team of atmospheric scientists have published their field study findings about unusual chemical reactions taking place in the Pearl River Delta in China during 2006.

Citation: Study investigates pressure-induced superconducting transition in electrides (2019, March 20) retrieved 18 August 2019 from https://phys.org/news/2019-03-pressure-induced-superconducting-transition-electrides.html Journal information: Physical Review Letters “Considering the wide potential applications of superconducting materials, the understanding of high-temperature superconductors is a key scientific challenge in condensed matter physics,” Aitor Bergara and Guochun Yang, two of the researchers who carried out the study, told Phys.org, via email. Electrides are ionic compounds in which most electrons reside at interstitial regions of the crystal and behave like anions. Due to their structural peculiarity, these compounds have interesting physical properties. For instance, the magnitude and distribution of their interstitial electrons can be effectively modulated, either by adjusting their chemical composition or external conditions, such as pressure. Overall, electrides are very poor superconductors. For example, the experimentally observed superconducting transition temperature of a canonical electride [Ca24Al28O64]4+ (4e-)4 is ~0.4 K. On the other hand, it is now well-known that, under high pressure, alkali metals can easily lose their outer orbital electrons and form electrides. “Interestingly, pressure-induced lithium (Li) electride is metallic,” Bergara and Yang said. “Additionally, phosphorus (P) presents a moderate electronegativity, so that they can trap some electrons in Li-rich Li-P compounds, while the remaining electrons may remain at interstitial regions. Thus, as we are predicting is this work, it would be possible to adjust the morphology of interstitial electrons by changing the ratio of Li and P and, therefore, obtain compounds with novel electronic properties. For example, according to our calculations, Li 6 P electride is predicted to have a superconducting transition temperature of 39.3 K, breaking the existing record among the electrides.”Predicting the atomic structure of materials from first principles (based only on their composition), is an extremely challenging task. It typically requires classifying a huge number of energy minima on a multidimensional energy surface lattice. In recent years, researchers have introduced several computation methods that can speed up this process, one of which is called CALYPSO. “In our study we have used the Calypso program developed by Yanming Ma and his colleagues at Jilin University, which implements a particle swarm optimization algorithm to determine the preferred crystal structures, just fixing the Li:P ratios and pressure as the only starting inputs,” Bergara and Yang explained. “Once the most stable structures are identified we have characterized their physical properties. For example, we have explored their superconducting properties within the McMillan-Allen-Dynes approximation.” In their study, Bergara, Yang and their colleagues reported that a pressure-induced stable Li6P electride can become a superconductor with a predicted superconducting transition temperature of 39.3K; the highest predicted so far in known electrides. They found that the compound’s interstitial electrons, with dumbbell-like connected electride states, play a dominant role in this superconducting transition. “Our prediction not only breaks the superconducting transition temperature record in the electrides, but also allows a better understanding of these materials,” Bergara and Yang said. According to the researchers’ predictions, other Li-rich phosphides, such as Li5P, Li11P2, Li15P2, and Li8P, could also be superconducting electrides, yet their Tc is expected to be lower. This recent study by Bergara, Yang and their colleagues could pave the way for further research exploring high-temperature superconductivity in similar binary compounds. “We believe that research into superconducting electrides has just begun,” Bergara and Yang said. “There is still a lot to be explored, for example, the analysis of the superconducting mechanism in novel electride compounds, especially under high pressure. As we have shown in this article, an effective way to design such superconducting materials is to explore metallic electride compounds formed between weak electronegative and strong electropositive elements.” New method yields higher transition temperature in superconducting materials The image on the left shows the atomic structure of the Li6P compound, and on the right the electronic charge density is plotted, where the electronic localization at the interstitials can be seen in red.

They always have. They want the oil, OK? They’ve always wanted that.” Trump has blamed both Democrats and former President George W Bush when talking about unrest in the Middle East, particularly citing Bush’s decision to invade Iraq in 2003.

Trump and Clinton have been involved in a war of words in recent weeks. Clinton had slammed Trump’s recent comments about banning Muslim immigrants, saying the Republican front-runner was “becoming ISIS’s best recruiter. He is becoming ISIS’s best recruiter. They are going to people showing videos of Trump insulting Islam and Muslims in order to recruit more radical jihadists,” she had said. Trump dismissed Clinton’s assertion that the Islamic State was using his videos as a recruitment tool saying she is “a liar” and “made up” the claim.

Last week, on Monday, The House Energy and Commerce Committee announced that Twitter CEO Jack Dorsey will testify before the committee regarding Twitter algorithms and content monitoring. The hearing is scheduled to take place on the afternoon of Wednesday, September 5, 2018. It is Wednesday, and Jack Dorsey has released a Testimony ahead of appearing before the committee today. Mid August, Jack Dorsey announced plans to rethink how Twitter works to combat fake news and data scandals. In July, Twitter deleted 70 million fake accounts in an attempt to curb fake news and improve Twitter algorithms. It has been constantly suspending fake accounts which are inauthentic, spammy or created via malicious automated bots. In his testimony, Dorsey has pushed back critics who have accused Twitter of censoring political content and not acting quickly enough to take down hateful expression. “Twitter does not use political ideology to make any decisions, whether related to ranking content on our service or how we enforce our rules.” His testimony provided information on four important factors that E&C sought answers for. Improving Twitter’s health Twitter algorithms Twitter’s work on Russian meddling of the 2016 elections Information on recent malicious activity Twitter saw on the platform. Twitter Healthcare Regarding Twitter’s health, Dorsey asserted that the platform has developed a more “comprehensive framework” to encourage healthy debate, conversations, and critical thinking. Earlier this year, Twitter began collaborating with the non-profit research center Cortico and the MIT Media Lab on exploring how to measure aspects of the health of the public sphere. They also requested outside experts for their proposed health metrics for Twitter. Following which the social platform is partnering with the University of Oxford and Leiden University and other academic institutions to better measure the health of Twitter, focusing on “informational echo chambers and unhealthy discourse on Twitter”. Twitter Algorithms In 2016, Twitter introduced a Home Timeline new ranking feature to show people the Tweets they might find most interesting first. Twitter also has a notification timeline that enables people to see who has liked, retweeted and replied to their Tweets, as well as who mentioned or followed them. Twitter algorithms also promote “Safe Search”. Per this mode, potentially sensitive content is excluded from search results, such as spam, adult content, and the accounts an individual has muted or blocked. Individual accounts may also mark their own posts as sensitive. Twitter also uses behavioral signals to determine how Tweets are organized. When a Tweet is identified as potentially detracting from a healthy conversation, it will only be available to view if you click on “Show more replies” or choose to see everything in your search setting. Using behavior signals, Twitter has had a 4 percent drop in abuse reports from search and 8 percent fewer abuse reports from conversations. In preparation for the hearing, Twitter data scientists analyzed Tweets sent by all members of the House and Senate that have Twitter accounts for a 30 day period spanning July 23, 2018 until August 13, 2018. They observed that there is no statistically significant difference between the number of times a Tweet by a Democrat is viewed versus a Tweet by a Republican. Their performance is the same because the Twitter platform itself does not take sides. Twitter’s work on Russian meddling of the 2016 elections After the meddling of Russian interference in US presidential elections in 2016, Twitter conducted a comprehensive platform activity. They identified 50,258 automated accounts that were Russian-linked and Tweeting election-related content. They also conducted an analysis of accounts that promoted election-related Tweets on the platform throughout 2016 in the form of paid ads. The two most active accounts were affiliated with Russia Today (“RT”), which Twitter subsequently barred from advertising. Per Dorsey’s testimony “Twitter’s main focus is on promoting healthy public discourse through protection of the democratic process. We must continue to work together with our elected officials, government partners, industry peers, outside experts, and other stakeholders so that the American people and the global community can understand the full context in which these threats arise.” Recent Malicious activity Twitter saw on its platform Twitter has suspended a total of 3,843 malicious accounts affiliated with the Russian Internet Research Agency. “As an example of Twitter’s ongoing efforts, Twitter identified 18 accounts in March 2018, believed to be linked to the Internet Research Agency uncovered by our ongoing additional reviews.” They have also suspended 770 accounts for violating Twitter policies in Iran. These accounts were in violation of Twitter’s platform manipulation policies and were engaged in coordinated activity intended to propagate messages artificially across accounts. Dorsey says, “Twitter has been in close contact with our industry peers about the malicious accounts located within Iran—we have received detailed information from them that has assisted us in our investigation, and we have shared our own details and work with other companies.” Dorsey ends his testimony saying that increased transparency is critical to promoting healthy public conversation on Twitter and earning trust. “We remain vigilant about identifying and eliminating abuse on the platform perpetrated by hostile foreign actors, and we will continue to invest in resources and leverage our technological capabilities to do so,” he wrote.
