Ubiquitous monitoring over wireless sensor networks (WSNs) is of increasing interest in industrial cyber-physical systems (CPSs). Question how to understand a situation physical system by estimating process parameters largely unexplored.

Time-based localization approaches attract a lot of interest due to their high accuracy and potentially low cost for wireless sensor networks (WSNs). However, time-based is tightly coupled with clock synchronization. Thus, the reliability timestamps in becomes an important yet challenging task deal with. In this paper, we propose robust strategies locate target node help anchors (nodes known positions) asynchronous networks. Two kinds are considered: one only offsets, labeled...
The localization of autonomous underwater vehicles (AUVs) in anchor-free environments has always been a difficult problem due to the lack global positioning systems and absolute references. In general, AUVs localize themselves by dead reckoning (DR), whereas error grows without bound. To alleviate growth errors, we propose intermittent belief propagation based (IBPDR) as cooperative (CL) framework. IBPDR, use DR periodically correct DR's deviation with CL methods. feature IBPDR reduces...
While myeloid‐derived suppressor cells (MDSCs) have been reported to participate in the promotion of angiogenesis and tumor growth, little is known about their presence function during perioperative period. Here, we demonstrated that human MDSCs expressing CD11b + , CD33 HLA‐DR – significantly increased lung cancer patients after thoracotomy. isolated 24 hr surgery from were more efficient promoting growth than before surgical operation allograft model. In addition, produced high levels...
Abstract The fatality of avian influenza A(H7N9) infection in humans was over 30%. To identify human genetic susceptibility to infection, we performed a genome-wide association study (GWAS) involving 102 patients and 106 heavily-exposed healthy poultry workers, sample size critically restricted by the small number cases. tackle stringent significance cutoff GWAS, utilized an artificial imputation program SnipSnip improve signals. In single-SNP analysis, one top SNPs rs13057866 LGALS1 . (AI)...
Most applications of underwater acoustic sensor networks (UASNs) rely on accurate location information targets. However, the asynchronous clock, stratification effect, and strong-noise characteristics environment make target localization more challenging as compared with terrestrial networks. This paper focuses an issue for targets, subjected to isogradient sound speed noise measurements. A network architecture including surface buoys, sensors, is first designed, where clocks sensors are not...
Interleukin (IL)-35 is an inhibitory cytokine consisting of IL-12A and Epstein-Barr virus-induced gene 3 (Ebi3) required by regulatory T-cells (Tregs) for maximal activity. During chronic hepatitis B virus (HBV) infection, Tregs have immunosuppressive effects on HBV-specific T helper (Th) cells, yet little known about the complex regulation their contribution to inadequate immune system response virus. In present study, we investigated whether IL-35 involved in HBV-related cellular...
The most common EGFR mutations in non-small cell lung cancer are exon 19 deletions and 21 point mutations, which both sensitive to EGFR-tyrosine kinase inhibitors. However, rare do exist how these respond tyrosine inhibitors is not well understood. A Chinese woman diagnosed with stage IV adenocarcinoma harbored a L747P (2239-2240 TT > CC) mutation, treatment gefitinib osimertinib failed achieve the desired effect. Herein, possible correlations between gene analysis outcomes of subsequent discussed.
Weak or absent virus-specific CD8+ T-cell responses to hepatitis B virus (HBV) infection are thought be responsible for persistent HBV infection. Previous studies have indicated that multiple inhibitory receptors, including lymphocyte activation gene-3 (LAG-3), can suppress the response in chronic viral This study aimed detect LAG-3 expression and investigate manner which immune is regulated balance strength of with extent liver injury The results showed levels were significantly higher T...
Underwater communications are fundamental techniques for the Internet of Things (IoUT) to establish information links among underwater devices. Recently, orthogonal chirp division multiplexing (OCDM) has drawn great attention in due its advantages dealing with burst interference both time and frequency domains. However, harsh channel conditions (e.g., multipath propagation, temporal variations, significant Doppler effects) have not been systematically considered current OCDM systems. In this...
ABSTRACT We detected Toxoplasma gondii in 29.3% (95% confidence interval [CI], 25.5% to 33.1%) of 550 insectivorous bats collected Myanmar. The genotyping these positive samples revealed they were closely related or belong clonal type I, which is highly virulent mice, showing that are potential reservoirs for T. transmission.

We consider the problem of node localization given partial pairwise distance measurements. Current solutions first complete missing distances and then apply classical multidimensional scaling (MDS) algorithm. Instead, we extend MDS to a setup where sensor network is composed fully connected group nodes that communicate with each other (e.g., beacons), cannot other, but one them communicates in group. The positions all are unknown. localize by exploiting their measurements disconnected nodes....
