Efficiency simulation and coincidence-summing correction for HPGe detector by ZHANG Ruiqin, LI Qi, FAN Yuanqing, ZHAO Yungang, ZHANG Xinjun, JIA Huaimao, NIU Yazhou, LI Ruiying, WANG Shilian

“…BackgroundIn order to enhance the detection sensitivity of HPGe detectors for measuring the low-level activity of radionuclides, samples are usually measured as close to the detector as possible to improve the detection efficiency, which inevitably leads to serious coincidence-summing effects in return and affects the accuracy of measured activity.PurposeThis study aims to conduct efficiency simulation and coincidence-summing correction for HPGe detectors.MethodsFirst of all, the peak efficiency of the HPGe detector was simulated by Geant4 and the internal geometry of the HPGe detector was optimized by comparing the simulated results with the experimental results of the mixed standard calibration source. …”

Energy-efficiency priority based beamforming design and optimization in IRS-assisted SWIPT system by Xiaorong XU, Weiwei ZHU, Jianrong BAO, Weiping ZHU, Wei FENG, Yingbiao YAO

“…Intelligent reflecting surface (IRS)-assisted simultaneous wireless information and power transfer (SWIPT) system is set as research background.Joint design and optimization of energy-efficiency priority based active beamforming at multi-antenna transmitter and passive beamforming at IRS were investigated.The optimization objective was to maximize minimum energy-efficiency, which was subject to transmitter power control, energy constraint at energy harvesting (EH) receiver and IRS phase shift constraint.Alternating direction method of multipliers (ADMM) was implemented to solve this non-linear non-convex optimization problem.Firstly, the fraction objective function was transformed via Dinkelbach’s approach.Singular value decomposition (SVD) andsemi-definite relaxation (SDR) were applied to obtain active beam forming vector at transmitter.Simulation results indicate that, IRS assisted SWIPT could significantly reduce energy threshold at EH receiver.The achievable energy-efficiency of the proposed strategy is 300 KB/J when total circuit power consumption is -15 dBm.Maximum energy-efficiency can be achieved with the maximum numbers of passive reflecting elements and transmitter antennas.…”

Evolution of the activities of states as reflected in legal and political Teachings by A. A. Klishin

“…The return of the law to its traditional, system-level basics that are clear to everyone taking part in the social relations is often facilitated by crises, such as the one in place today when the existing challenges and problems are complemented by the objective force majeure events like the virus attack in 2020 which the amorphous “network-based” instruments or not entirely just and efficient elements of the “international legal order” cannot cope with, as opposed to the active governmental and legal mechanisms of sovereign states capable of ensuring the balance of legal instruments and administrative levers of management in crisis situations.MATERIALS AND METHODS. …”

Impact of short-term germination on dehulling efficiency, enzymatic activities, and chemical composition of mung bean seeds (Vigna radiata L.) by Christina Wintersohle, Sophie Julia Arnold, Hanna Marie Geis, Franziska Keutgen, Lara Etzbach, Ute Schweiggert-Weisz

“…Mung bean seeds were soaked overnight and germinated in the dark for 4, 8, 12, 24, 32, and 48 h, with the effects on dehulling efficiency, enzymatic activities, and chemical composition, including antinutritional factors, examined.After 48 h of germination, a substantial increase in enzyme activities was observed: lipolytic activities increased by 644 %, amylolytic activities by 200 %, and polyphenol oxidase activity by 280 %. …”
