Airborne Wireless Sensor Networks for Airplane Monitoring System

In traditional airplane monitoring system (AMS), data sensed from strain, vibration, ultrasound of structures or temperature, and humidity in cabin environment are transmitted to central data repository via wires. However, drawbacks still exist in wired AMS such as expensive installation and maintenance, and complicated wired connections. In recent years, accumulating interest has been drawn to performing AMS via airborne wireless sensor network (AWSN) system with the advantages of flexibility, low cost, and easy deployment. In this review, we present an overview of AMS and AWSN and demonstrate the requirements of AWSN for AMS particularly. Furthermore, existing wireless hardware prototypes and network communication schemes of AWSN are investigated according to these requirements. This paper will improve the understanding of how the AWSN design under AMS acquires sensor data accurately and carries out network communication efficiently, providing insights into prognostics and health management (PHM) for AMS in future

Diabetes-associated neutrophil NETosis: pathogenesis and interventional target of diabetic complications

Neutrophil extracellular traps (NETs) are known as extracellular fibers networks consisting of antimicrobial proteins and decondensated chromatin DNA released by activated neutrophils. NETosis is a NETs-induced neutrophilic cell death which is unique from necrosis or apoptosis. Besides its neutralizing pathogen, NETosis plays a crucial role in diabetes and diabetes-related complications. In patients with diabetes, NETs-releasing products are significantly elevated in blood, and these findings confirm the association of NETosis and diabetic complications, including diabetic wound healing, diabetic retinopathy, and atherosclerosis. This article briefly summarizes the mechanisms of NETosis and discusses its contribution to the pathogenesis of diabetes-related complications and suggests new therapeutic targets by some small molecule compounds

Surface skyrmions and dual topological Hall effect in antiferromagnetic topological insulator EuCd2_2As2_2

In this work, we synthesized single crystal of EuCd$_2$As$_2$, which exhibits A-type antiferromagnetic (AFM) order with in-plane spin orientation below $T_N$ = 9.5~K.Optical spectroscopy and transport measurements suggest its topological insulator (TI) nature with an insulating gap around 0.1eV. Remarkably, a dual topological Hall resistivity that exhibits same magnitude but opposite signs in the positive to negative and negative to positive magnetic field hysteresis branches emerges below 20~K. With magnetic force microscopy (MFM) images and numerical simulations, we attribute the dual topological Hall effect to the N\'{e}el-type skyrmions stabilized by the interactions between topological surface states and magnetism, and the sign reversal in different hysteresis branches indicates potential coexistence of skyrmions and antiskyrmions. Our work uncovers a unique two-dimensional (2D) magnetism on the surface of intrinsic AFM TI, providing a promising platform for novel topological quantum states and AFM spintronic applications.Comment: 7 pages, 3 figure

Learning from experience in Hangzhou: WLCE leisure experience research opportunity

This text was collaboratively written by the 12 students – from Brazil, Canada, China, Hong Kong and Hungary – who participated in the WLCE Leisure Experience Research Opportunity, a fieldwork project focusing on resident, national and international visitors to the Chinese city of Hangzhou. The project, designed and implemented by the WLO, was supported by the Hangzhou Municipal Bureau of Commerce and Hangzhou Commerce and Tourism Group, and supervised by Dr. Marcel Bastiaansen (Breda University of Applied Sciences, the Netherlands), Dr. Marie Young (University of the Western Cape, South Africa) and Dr. Isabel Verdet (WLO Secretariat)

The enormous repetitive Antarctic krill genome reveals environmental adaptations and population insights

Antarctic krill (Euphausia superba) is Earth’smost abundant wild animal, and its enormous biomass is vital to the Southern Ocean ecosystem. Here, we report a 48.01-Gb chromosome-level Antarctic krill genome, whose large genome size appears to have resulted from inter-genic transposable element expansions. Our assembly reveals the molecular architecture of the Antarctic krill circadian clock and uncovers expanded gene families associated with molting and energy metabolism, providing insights into adaptations to the cold and highly seasonal Antarctic environment. Population-level genome re-sequencing from four geographical sites around the Antarctic continent reveals no clear population structure but highlights natural selection associated with environmental variables. An apparent drastic reduction in krill population size 10 mya and a subsequent rebound 100 thousand years ago coincides with climate change events. Our findings uncover the genomic basis of Antarctic krill adaptations to the Southern Ocean and provide valuable resources for future Antarctic research

The effects of the method and dose of cyclophosphamide administration on cashmere shedding

The objective of this study was to investigate the effects of the method and dose of cyclophosphamide (CPA) administration on cashmere shedding. Thirtytwo castrated Liaoning cashmere goats were randomly allotted to four groups, with eight replicates in each group. Goats in the four groups were injected intravenously or intramuscularly with CPA at doses of 20 or 25 mg kg−1 body weight (BW), respectively. Feed intake and BW were recorded, and erythrocyte count, hemoglobin content, and cashmere weight were determined. It was found that the CPA administration method had no significant effect on feed intake or BW of cashmere goats. Cyclophosphamide injection can significantly decrease the erythrocyte count and hemoglobin content of cashmere goats, but the effects are dependent on injection method and CPA dose. The injection method and dose did not significantly influence cashmere weight, but the method had significant effects on time to initiate shedding and regrown hair length. Regrown hair was longest by intramuscular injection with 20 mg kg−1 BW, which also caused the least erythema on the epidermis during the days after shedding. The results indicate that the CPA administration method can significantly influence cashmere shedding. Intramuscular injection of CPA at a dose of 20 mg kg−1 BW was found to be relatively beneficial for hair removal and regrowth in cashmere goat
