Abstract Freshwater bivalves (Bivalvia, Unionida) are one of the most threatened groups animals in world. Defining species boundaries and understanding phylogeny genetic diversity these is key to guiding their conservation management. However, presence significant phenotypic plasticity convergence within this group complicates delimitation. This includes freshwater mussel genus Nodularia , endemic East Asia, for which a comprehensive phylogenetic relationships remains elusive due inadequate...

Background: Parkinson's disease (PD) represents a prevalent neurodegenerative condition that leads to significant disability and contributes growing public health challenge worldwide. However, comprehensive report on progress from 1990 2021 is still lacking, especially regarding the risk factors associated with PD by gender age. This study aims examine patterns of incidence, mortality rates, disability-adjusted life years (DALYs) across all age groups, along linked PD-related fatalities,...

Ampicillin, a β-lactam antibiotic frequently prescribed for bacterial infections, is used off-label in neonates. Blood sampling limitations neonatal pharmacokinetic (PK) studies make dried blood spots (DBS) promising matrix micro-sampling. This study aims to develop population PK (PopPK) model using DBS-based approach optimize ampicillin dosing Chinese patients. DBS samples were collected at predefined intervals from patients after dosing. A PopPK was developed NONMEM 7.5, followed by...

We study the problem of energy-efficient target tracking in underwater wireless sensor networks (UWSNs). Since sensors UWSNs are battery-powered, it is impracticable to replace batteries when exhausted. This means that battery life affects lifetime whole network. In order extend network lifetime, worth reducing energy consumption on premise sufficient accuracy. paper proposes an filter implements tradeoff between communication cost and Under distributed fusion framework, local should not...

Abstract: Three new species of Chresmodidae are described. They belong to two different genera: Chresmoda multinervis sp. nov., shihi nov. and Jurachresmoda sanyica A study the forewing venation is provided. Longitudinal veins mostly parallel; costal area broad at basal narrowing distally; ScP probably extending close wing apex; R parallel length ScP; MA running R, with long branches; branched‐off basally; while MP not branched until middle wing. However, important part CuP poorly preserved....

The well known and most important function of nucleoli is ribosome biogenesis. However, the nucleolus showed delayed development malfunction in somatic cell nuclear transfer (NT) embryos. Previous studies indicated that nearly half rRNA genes (rDNA) cells were inactive not transcribed. We compared rDNA methylation level, active nucleolar organizer region (NORs) numbers, proteins (upstream binding factor (UBF), nucleophosmin (B23)) distribution, nucleolar-related gene expression three...

Target tracking is one of the broad applications underwater wireless sensor networks (UWSNs). Sensors UWSNs are battery-powered and it impracticable to replace batteries when exhausted. That means life affecting lifetime whole networks. So, worth reducing energy consumption on premise satisfactory accuracy. This paper proposes an adaptive scheduling scheme that implements for accurately energy-efficiently a maneuvering target detected by UWSNs. employs multi-sensor achieve task. A priori...

Interactions between plants and insects are among the most important life functions for all organism at a particular natural community. Usually large number of samples required to identify insect diets in food web studies. Previously, Sanger sequencing next generation (NGS) with short DNA barcodes were used, resulting low species-level identification; meanwhile costs expensive metabarcoding together more samples. Here, we present fast effective strategy larvae Lepidoptera their same time...

Target tracking is one of the broad applications underwater wireless sensor networks (UWSNs). However, as a result temporal and spatial variability acoustic channels, communications suffer from an extremely limited bandwidth. In order to reduce network congestion, it important shorten length data transmitted local sensors fusion center by quantization. Although quantization can bandwidth cost, also brings about bad performance information loss after To solve this problem, paper proposes...
