Sarcopenia, the accelerated loss of muscle mass and function, is commonly associated with aging, especially in older adults. While low serum calcium has been linked to individuals over 50, its relationship sarcopenia younger adults (20-60 years) unclear. This study examines this association using data from National Health Nutrition Examination Survey (NHANES) 2011 2018. population-based, cross-sectional analyzed participants aged 20-60 NHANES 2011-2018. Individuals missing were excluded....

A numerical investigation is conducted for the initial boundary value problem of Korteweg–de Vries (KdV) equation with homogeneous conditions. Using average implicit difference discretization, a second-order theoretical accuracy in time achieved. For spatial direction, center-symmetric discretization coupled extrapolation technique employed, yielding three-level linear method sixth-order accuracy. Consequently, integration these methods results finite scheme that accurately simulates two...

Two numerical methods are investigated for the initial–boundary value problem of a nonlinear Rosenau–KdV–RLW equation with homogeneous boundary conditions. With premise achieving second-order theoretical accuracy in temporal direction, two-level linearization discretization and three-level extrapolated applied to terms, respectively. To achieve higher spatial Richardson extrapolation combination technique is employed; thereby, linearized difference scheme linear proposed, both O(τ2+h4). The...

Sea cucumber Apostichopus japonicus is an important economic species in China, which affected by various diseases; skin ulceration syndrome (SUS) the most serious. In this study, we characterized transcriptomes A. challenged with Vibrio splendidus to elucidate changes gene expression throughout three stages of SUS progression. RNA sequencing 21 cDNA libraries from tissues and developmental SUS-affected yielded 553 million raw reads, 542 high-quality reads were generated deep-sequencing using...

The hardware impairments of transceiver nodes that generate signal distortions degrade the reliability performance communication systems. This paper investigates impact imperfections on outage hybrid satellite-terrestrial relay systems (HSTRS), where a geosynchronous earth orbit (GEO) satellite transmits its data to terrestrial destination with help decode-and-forward (DF) relays. We consider all network are subjected and propose multi-relay selection (MRS) scheme enhance HSTRS. traditional...

Customarily, retarders serve as the setting time regulators of cement-based composites to meet demands various construction environments. However, limited ability adjust restricts application polysaccharides in special In this study, we reported a naturally high-efficiency retarder, konjac glucomannan (KGM), and studied mechanism its effect on hydration ordinary Portland cement. Incorporating KGM could significantly prolong cement without strength damage. Furthermore, active hydroxyl group...

Log periodic dipole array (LPDA) antennas are one of the most widely used antenna types for normalized site attenuation (NSA) and radiated emission (RE) testing. A thorough understanding possible error sources associated with calibration application LPDAs EMC tests over a ground plane is essential evaluating minimizing measurement uncertainties. Systematic errors present in standard NSA measurement, which independent random effects equipment In an effort to determine on RE testing, these...

In order to understand the effects of seasonal change on immunity sea cucumber Apostichopus japonicus cultured in pond, A. with body weight 12.2 ± 4.5 g (sample A) and 32.6 7.1 B), respectively, were collected monthly randomly from a typical pond during year cycle employed for evaluation immunocompetence. Simultaneously, environmental factors including water temperature, pH, salinity dissolved oxygen (DO) measured using handheld multiparameter meter. The activities acid phosphatase (ACP),...

In recent years, sea cucumber has become a favorite healthcare food due to its characteristic prevention of cardiovascular diseases, suppression tumors, as well enhancement immunity. order screen the anti-tumoral proteins or peptides from (Apostichopus japonicus), cDNA library was analyzed, and disintegrin-like metalloproteinase with thrombospondin type 1 motif, member 13 (ADAMTS13)-like found. ADAMTS13-like contains 10 (TSP1) domains. Based on analysis bioinformatics, third TSP1 domain this...

Background: As one of the essential pieces chemical equipment, a reactor provides necessary reaction space and conditions for materials involved in during stirring process. However, under typical operating conditions, issues such as uneven gas distribution, suboptimal gas-liquid mixing, low product yield often arise phase reactors. Purpose: To address prevalent current stirred reactors, new design equipped with double-suction turbine agitator was developed. Method: In this paper, designed,...

The increasing demand for sensors and systems that use RF communication in one form or another modern vehicles is driving the growing degree of complexity control system density. For many these systems, it necessary to perform some level individual performance evaluation may involve an over air component assessment. Although this be just aspect overall operation, could a vital part since there are external environmental factors outside have profound impact on performance. importance...

Rates of neutron production in deuterium-tritium (D-T) plasmas below the temperature 100 keV have been widely studied with analytical cross sections based on nuclear physics. In present work, a new algorithm numerical simulation using latest database ENDF/B-VII, discrete ordinate (SN) method, and Monte Carlo methods was developed to describe reactions D-T plasma. Compared method that used section, this can predict reaction plasma several hundreds kilo-electron-volts has potential give...
