A hybrid architecture is presented for downlink beamforming (BF) with phased antenna arrays (PAA) in indoor 60 GHz spatial division multiple access (SDMA) channels. To manage the multiple access and inter-symbol interferences (MAI/ISI) encountered in SDMA with limited feedbacks, a cost-effective time-domain hybrid BF (HBF) method is presented to exploit the directivity provided by PAA in radio frequency (RF) beam patterns and the spatial diversity offered by multiple baseband processing modules. To maintain signal qualities under unpredictable MAI/ISI in wireless multimedia streaming to which indoor 60 GHz radio mainly applies, robust beamformers are designed to maintain the signal to interference-plus-noise ratio (SINR) for each user with minimum total transmit power. The percentages in which the target SINRs can be satisfied with the proposed HBF schemes are found sensitive to uncertainties in the phase shifters of PAA. Two kinds of robust formulations are thus proposed to jointly combat the MAI, ISI and phase uncertainties. Robust beamformers with semi closed-form expressions can be obtained with a nonlinear kind of them, whose SINR satisfaction ratio can attain 80% or more by extensive simulations in an indoor two-user 60 GHz environment if RF beam patterns of the users do not highly overlap in space. © 2013 IEEE.

An HPLC-DAD method was developed to detect and quantify a neonicotinoid insecticide acetamiprid (ATP) and its metabolite IM-1-2 in autopsy samples of a fatal intoxication case. The postmortem blood and tissue distribution of ATP and IM-1-2 was determined for the first time. The method showed acceptable precisions and recoveries with relative standard deviations of <10% for ATP level and 1.38 % for IM-1-2. The detection and quantification limits for ATP were 0.015 μg/mL and 0.030 μg/mL for blood and were 0.035 μg/g and 0.050 μg/g for liver samples, respectively. The mean contents of ATP were 0.79 μg/g in the liver, 47.35 μg/g in the stomach contents and 2.7 μg/mL in the blood. IM-1-2 content was 17.0 μg/g in the stomach contents. ATP and IM-1-2 were not detected in the urine. The presence of ATP and IM-1-2 in the samples was confirmed by GC-MS. The method can be exploited in future forensic casework. © 2013 American Academy of Forensic Sciences. Source

HEMOLIA is a new generation Anti-Money Laundering (AML) intelligent multi-agent alert and investigation system which in addition to the traditional financial data makes extensive use of modern societys huge telecom data source, thereby opening up a new dimension of capabilities to all Money Laundering fighters (FIUs, LEAs) and Financial Institutes (Banks, Insurance Companies, etc.). Adding the Telecom Plane to the existing Financial Plane may improve and dramatically change AML doctrines, since another dimension is added to the analysis and investigation processes. HEMOLIA, taking into account existing legal frameworks, will hybridize and correlate the Financial and Telecom Planes in order to create richer and more accurate alerts, intelligence and investigation tools, as well as information sharing, both nationally and internationally. A major part of HEMOLIA will be the legal research and provision of legal guidelines to all ML fighters. To respect privacy rights HEMOLIA will bring a new model of Push Privacy Preserving Alerts where all FIUs and FIs are pushed with alerts that mark a transaction or customer with a money laundering / fraud risk level or risk probability, yet without disclosing any private data. This model may have outstanding impact on AML because it means that FIs will be alerted based on data of all other FIs and based on Telecom service providers at the national and international level, opening up a new era of Money Laundering and financial crime reporting by FIs to FIUs. The HEMOLIA consortium includes 2 end users (Belgium FIU, Ministry of Justice of Poland) and 7 technological partners which bring together European SMEs, industries and academies, ranging from system and database design through to money laundering detection. HEMOLIA will be tested in an environment which simulates live network and systems of 3 different countries which have implemented the HEMOLIA concept and which will cooperate together to share AML information.
Despite decades of intellectual isolation, the Soviet Union produced some fine science. When it imploded, only a wave of foreign aid and philanthropy protected that excellent research base from collapse. The strategy worked: as individualism and entrepreneurship took hold in Russia, science regained its strength and started to look outwards — as any successful research endeavour must in the twenty-first century. Yet Russian President Vladimir Putin believes that his country can increasingly go its own way, and centralism and anti-Western rhetoric are on the rise. Science is beginning to suffer from paranoid state control. As we report on page 486, Russia has placed strict new rules on how its scientists can operate. In response to a recently amended law, Russian universities and research institutes have begun to instruct scientists to seek permission from the Federal Security Service before they submit papers or give talks at scientific conferences.. The wording of the law is vague, seemingly deliberately so. It effectively requires any work that is applicable to industry to be approved for publication. Russian scientists are rightly outraged by this return to inglorious Soviet practices. Meanwhile, dozens of organizations that receive foreign funding (and which the Russian government suspects are involved in “political activities” — again vaguely defined) are under scrutiny. Officially, this is to identify and repel unwelcome foreign influence. Unofficially, there is a whiff of political scores being settled. In May, the Dynasty Foundation, Russia’s largest private science-funding organization, shut down after the Ministry of Justice labelled it a “foreign agent”. Other philanthropic groups and foreign-funded foundations fear that they may soon find themselves on a list of “undesirable” organizations that the Russian parliament is drawing up. This is not the 1960s. Today, fear and isolationism can only damage collaborative science. In turn, this will undermine Russia’s efforts to modernize its struggling economy. Putin knows only too well that his country’s dependence on oil and gas exports is a treacherous anachronism as the world steers away from fossil-fuel use. Wisely, the government has substantially stepped up its science funding in recent years. But neither a multibillion-rouble nanotechnology initiative, launched in 2007, nor attempts to create a number of world-class research universities and attract top Western scientists to Russian labs will bear fruit if fear and distrust continue to stand in the way of a liberal science culture. Russia’s annexation of the Crimean Peninsula last year, and its dubious role in the ongoing conflict in the rest of Ukraine, chilled East–West collaborations, in science and other fields. Russia’s controversial military involvement in the civil war in Syria, although cautiously tolerated by Western powers, threatens to cause further tension. Through large European research facilities such as the particle-physics laboratory CERN and the international nuclear-fusion project ITER, science can still offer a much-needed peaceful counterbalance in these politically turbulent times. But a disturbingly anti-Western speech to the upper chamber of the Russian parliament by Putin’s top science adviser on 30 September — the same day that Russia began its air strikes in Syria — testifies to the level of misunderstanding that is currently poisoning East–West relations across the board. The speech by Mikhail Kovalchuk, director of the Kurchatov Institute of nuclear science in Moscow and a key contact for many international collaborations, delivered a patently absurd account, riddled with lies and propaganda, of how international science is a US plot to undermine Russia. Such anti-Western sentiments are readily echoed in Russia: last week, a high-ranking IT adviser to the government said that Russia should stop training computer experts because they will before long be serving Western interests. Making a bogeyman of the outside world — and in particular of the United States — is a populist political strategy intended to prepare the ground for anti-liberal isolationism. For Russia’s scientific community, a crackdown on academic freedom and foreign support will be devastating. Putin, who frequently expresses his appreciation of science, must see that investment alone is not enough. To pour cash into a system that stifles intuition, brilliance and truth will not help a nation that has always held scientists and explorers in great esteem. Even through difficult economic and political times, Russian science has produced a never-ending supply of great minds. It needs the freedom and respect to continue to do so.

Inmates in the U.K. have been organizing deliveries of drugs and electronics via small drones, The Sun reports. Over the weekend, The Sun reported a drone crash at the Category B Bullingdon jail in Bicester, Oxfordshire. The drone contained large amounts of cannabis, as well as cellphones and chargers. "The drone was in a part of the jail without CCTV," an insider told The Sun. "It was well-planned. We’ve no idea how many times this method of smuggling has been used before." But this crash is just the latest in a string of drone drops—according to the U.K. Ministry of Justice, at least nine drones have attempted to infiltrate prisons in the U.K. in the first half of 2015. The potential security threat reaches beyond smuggled drugs or luxury items, as drones could also be used to carry guns or other weapons. For now, the penalty for smuggling illegal supplies into a prison is two years in jail, but parts of the U.K. are calling for more serious consequences. In September, a Prison Service spokesman told the BBC, "We are introducing new legislation to further strengthen our powers, making it illegal to land a drone in prison or to use a drone to drop in psychoactive substances."
