It has been verified that, as an emerging contaminant, microplastics are capable of adsorbing certain traditional contaminants like the heavy metal Cd. However, majority previous studies only focused on types virgin microplastics, especially for PE and PS. In addition, this adsorption process might be affected by inevitably undergoing aging consequent changes in natural environment. Unfortunately, relevant reports effects were mainly about organic pollutants, rather than metals. By far,...

Metal phosphorus trichalcogenides ($\mathrm{MP}{\mathrm{X}}_{3}$) constitute a vast family of van der Waals materials, comprising more than four dozen candidates with versatile properties spanning spin crossover, catalysis, and pressure-induced superconductivity. While exceptions exist, such as $\mathrm{SnPS}{\mathrm{e}}_{3}$, which adopts both 2D 3D crystalline structures, its isomer recently exhibiting superconductivity under high pressure, the investigation counterpart presents an...

Rheumatoid arthritis (RA) is a chronic autoimmune disorder characterized by joint inflammation, leading to pain, swelling, stiffness, and damage. Mesenchymal stem cell-derived extracellular vesicles (MSC-EVs) hold significant promise as therapeutic agents owing their potent paracrine activities. This study investigated the anti-inflammatory effects of human umbilical cordderived MSC (hUCSC)-EVs overexpressing miR-124 in collagen-induced (CIA). hUCSCs were transfected with miR-124, hUCSC-EVs...

Abstract Intermittent loads, such as grinders and welders, are the main factors that degrade power quality in distribution system. loads will result voltage fluctuations with stochastic characteristics, which may lead to malfunction of other sensitive loads. This paper uses cumulant method calculate bus fluctuation using algebraic addition multiplication. The probability density function can be further expressed by Gram‐Charlier series expansion. Compared traditional methods, computation...

An extended generalised spatial modulation (E-GSM) technique is proposed. Unlike the conventional (SM) schemes where number of activated transmit antennas (TAs) has been fixed, E-GSM scheme employs variable TAs to represent explicit symbol, which makes fuller use antenna combinations (TACs) and thus, enhances spectral efficiency. The average bit error ratio proposed derived in a closed-form expression theoretical analysis agrees well with numerical results. In addition, further improve...

摘要: 基于COSTAS环的载波同步环路在对大频偏OQPSK信号进行载波同步时，所需的入锁时间较长，不能满足突发信号的处理要求。针对这一问题，该文将OQPSK信号的平方谱与载波同步环路相结合设计了改进算法。仿真结果显示，改进算法比传统算法的估计精度更高；在信噪比高于6 dB时，入锁时间短、误比特率接近理论限，满足大频偏突发信号的处理要求。 关键词: OQPSK信号 / 载波同步 平方谱 COSTAS环

On June 15, 2007 a great tragedy occurred due to ship collision with bridge pier which resulted in nine fatalities Guangdong Providence, China. This event greatly increased concern over the safety of bridges crossing navigable waterways.
