Supply Chain Finance (SCF) is a new type of financing business carried out by commercial banks on the basis supply chain management, which effectively promotes healthy development chain. As most typical mode SCF, accounts receivable can use part occupying working capital for financing, widely used. In order to manage credit risk in and maintain operation chain, this paper proposes financial pre...
BACKGROUND Glycated albumin (GA) has been increasingly used as a reliable index for short-term glycemic monitoring, and is inversely associated with β-cell function. Because the pathophysiologic nature of type 2 diabetes (T2D) is characterized by progressive decline in insulin secretion, the aim was to determine whether GA levels were affected by diabetes duration in subjects with T2D. METHOD...
Whether on the scale of a single cell, organ or organism, glutamine homeostasis is to a large extent determined by the activities of glutaminase (GA, EC 3.5.1.2) and glutamine synthetase (GS, EC 6.3.1.2), the two enzymes that are the focus of this report. GA and GS each provide examples of regulation of gene expression at many different levels. In the case of GA, two different genes (hepatic- a...
In this paper, a multi-objective genetic agorithm to solve assembly line balancing problems is proposed. The performance criteria considered are the number of workstations, the line efficiency, the smoothness index before trade and transfer, and the smoothness index after trade and transfer. The developed genetic algorithm is compared with six popular heuristic algorithms, namely, ranked positi...
In application to numerical analysis of geotechnical problems, the limit-state surface is usually not known in any closed form. The probability of failure can be assessed via the so-called reliability index. A minimization problem can naturally be formed with an implicit equality constraint defined as the limit-state function and optimization methods can be used for such problems. In this paper...
PURPOSE To document incidence of and risk factors for development of retinopathy of prematurity (ROP) in a population of low birthweight infants (< 1500 g). METHODS The authors registered clinical characteristics (birthweight, gestational age (GA), Clinical Risk Index for Babies (CRIB), Apgar score, respiratory characteristics (intubation, ventilation, respiratory support, supplemental oxygen...
OBJECTIVE The glycemic index (GI) of dietary carbohydrate is thought to affect glucose homeostasis. Recently, the Effect of Amount and Type of Dietary Carbohydrates on Risk for Cardiovascular Heart Disease and Diabetes Study (OmniCarb) trial reported that a low-GI diet did not improve insulin sensitivity. We conducted this ancillary study of the OmniCarb trial to determine the effects of GI and...
We investigated a possible association of peroxisome proliferator-activated receptor gamma coactivator-1 alpha (PGC-1α) Gly482Ser polymorphism with hypertension in Mongolians in Inner Mongolia. A total of 787 subjects were enrolled randomly, including 390 hypertension patients and 397 healthy controls. Triglycerides, cholesterol, and fasting plasma glucose were measured, and body mass inde...
a new structure learning approach for bayesian networks (bns) based on asexual reproduction optimization (aro) is proposed in this letter. aro can be essentially considered as an evolutionary based algorithm that mathematically models the budding mechanism of asexual reproduction. in aro, a parent produces a bud through a reproduction operator; thereafter the parent and its bud compete to survi...
PURPOSE To develop a predictive model based on quantitative characteristics of geographic atrophy (GA) to estimate future potential regions of GA growth. DESIGN Progression study and predictive model. PARTICIPANTS One hundred eighteen spectral-domain (SD) optical coherence tomography (OCT) scans of 38 eyes in 29 patients. METHODS Imaging features of GA quantifying its extent and location,...
