Patent foramen ovale (PFO) is a congenital defect between the atria, resulting in abnormal hemodynamics. We conducted genome-wide association study (GWAS) to identify common genetic variants associated with PFO. performed whole genome sequencing discovery cohort of 3,227 unrelated Chinese participants screened for PFO via contrast transthoracic echocardiography (cTTE). Single-nucleotide polymorphisms (SNPs) were further validated by Sanger and subsequently evaluated validation cohort....

This study aimed to examine the impact of PM2.5 and its constituents on small for gestational age (SGA). We collected records 8082 twin pairs their mothers from 21 hospitals across China. Concentrations were Tracking Air Pollution dataset. Generalized linear models utilized in this observational explore relationship between SGA PM2.5. An increase by one interquartile range during pregnancy was linked a 17 % increased risk (OR = 1.17, 95 CI: 1.05-1.31), with population attributable fraction...

We successfully achieved the phosphorylation of secondary aromatic alcohols with H-phosphine oxides (less developed system) using phosphotungstic acid as a catalyst in dimethyl carbonate. The system was simple and environmentally friendly showed better activity than traditional Lewis or Brønsted acids such FeCl3, p-TsOH·H2O, etc., generating up to 97% isolated yield. Control experiments indicated that reaction did not occur through radical pathway, ethers carbocation were key intermediates pathway.

Abstract Background The American College of Medical Genetics and Genomics (ACMG)/Association for Molecular Pathology (AMP) guidelines recommend using variant enrichment among cases as "strong" evidence pathogenicity per the PS4 criterion. However, quantitative support thresholds from real-world Mendelian case–control cohorts is lacking. Methods To address this gap, we evaluated established data Chinese Deafness Consortium. A total 9,050 variants 13,845 patients with hearing loss (HL) 6,570...

Due to difficulties on improving point‐to‐point physical wireless link capacity, it is necessary study relay network communications under structured idea. In this paper, Solar System satellite constellation proposed for Earth‐Mars communications, including mission background, mathematic model, topology design, analysis....

Since great redundancy of telemetry data spacecraft, compression is a good solution for the limited bandwidth and contact wireless links. It important to obtain accurate characteristic firstly. State-of-the-art machine learning methods work well on mining pattern recognition under conditions given test set, which could be used as available tools post-event processing analysis, such trend forecasting outlier detection, but they have not provided proper from source on-board. In this paper,...

Optimizing deployment of charging base stations in wireless rechargeable sensor networks can considerably reduce the cost. Previously, are simply installed at some fixed special points (e.g., grid points) after partitioning area distributed by nodes. In this paper, a new algorithm planning is proposed based on greedy and location relationship The exploits local search ability avoids falling into an exponential increase number (i.e., combinatorial explosion). simulated results show that...

In this paper, we proposed a new approach to model video traffic H.263 encoded.

Conventional constant modulus algorithms (CMAs) suffer shortcomings of slow convergence rate and possibility improper convergence, which obstruct their application in real-time multiuser detection for CDMA cellular system. This paper focuses on developing new to alleviate these problems. Three CMAs, recursive variable step size CMA, normalized constrained CMA are obtained under a uniform framework. Interestingly they can be expressed general form. Since automatically adaptively choose the...

In current Mars relay communications, the Consultative Committee for Space Data Systems (CCSDS) Proximity-1 protocol is simple and efficient but it exhibits low flexibility in optimal access orbiter selection. Once connected with first successful hailing orbiter, rover would not switch to other better orbiters until end of that connection, which makes difficult provide more convenient data services. The entire system cost essential selection, includes both links' transmission concerned...
