PURPOSE To determine whether perioperative desaturation (PD) in preschool children undergoing non-cardiac surgery is associated with subsequent impairment of intelligence or subsequent change in age-specific weight and height percentile. METHOD A historical-concurrent follow-up study was conducted in children aged ≤ 60 months who underwent general anesthesia (GA) for non-cardiac surgery betwe...
if both reference station (rs) and navigational device in differential global positioning system (dgps) receive signals from the same satellite, rs position components error (rpce) can be used to compensate for navigational device error. this research used hybrid method for rpce prediction which was collected by a low-cost gps receiver. it is a combination of genetic algorithm (ga) computing an...
BACKGROUND The aim of the present study was to investigate the serum levels of endothelial progenitor cells (EPCs) in type 2 diabetic patients without documented ischemic disease and the association between EPCs and atherosclerotic plaque formation in the carotid artery. METHODS AND RESULTS A clinic-based, prospective study of type 2 diabetic patients was conducted. A total of 73 subjects wer...
Parallel robots have been used in a large number of applications ranging from astronomy to flight simulators and are becoming increasingly popular in the field of construction industry. This paper is aimed at presenting a study on the optimization of the BIGLIDE and BIPOD parallel robots, which comprises two-degree-of-freedom (DOF) parallel robots with constant and variable struts. The robot wo...
Dwarf stature is introduced to improve lodging resistance and harvest index in crop production. In many crops including maize, mining and application of novel dwarf genes are urgent to overcome genetic bottleneck and vulnerability during breeding improvement. Here we report the characterization and expression profiling analysis of a newly identified maize dwarf mutant Dwarf11 (D11). The D11 dis...
Abstract The author proposes a model evaluation based on the GA-SVM to better understand of company’s relationship and core competitiveness. system index is reduced by relative gray analysis, support vector machine optimized genetic algorithm, specific algorithm steps are introduced. Select models from top 100 enterprises in China’s construction industry 2020 published China Construction Indust...
Purpose: Among black transgender women (transwomen) at high risk of HIV acquisition or already living with HIV/AIDS, the study examined whether medical or socially based gender affirming factors may contribute differentially to selected measures of resiliency, perceived stress, and a scale measure of mental health outcomes. This question has implications for clinical care and counseling of this...
BACKGROUND AND OBJECTIVES Available data on survival rates and outcomes of extremely low gestational age (GA) infants (22-25 weeks' gestation) display wide variation by country. Whether similar variation is found in statements by national professional bodies is unknown. The objectives were to perform a systematic review of management from scientific and professional organizations for delivery r...
