Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：Estimation of Common Factors for Microstructure Noise and Effcient Price in a High-frequency Dual Factor Model
高频双因子模型 微结构 噪声公因数 效率价格 估计
2023/4/17
We develop the Double Principal Component Analysis (DPCA) based on a dual factor structure for high-frequency intraday returns contaminated by microstructure noise. The dual factor structure allows a ...
Dietary glycemic load assessed by food-frequency questionnaire in relation to plasma high-density-lipoprotein cholesterol and fasting plasma triacylglycerols in postmenopausal women
glycemic index glycemic load women
2016/6/12
In metabolic studies, both greater carbohydrate
intakes and higher glycemic indexes (GIs) raise fasting triacylglycerol
concentrations. In epidemiologic studies, dietary
glycemic load (GL) is posit...
Validation of a self-administered food-frequency questionnaire administered in the European Prospective Investigation into Cancer and Nutrition (EPIC) Study: comparison of energy, protein, and macronutrient intakes estimated with the doubly labeled water, urinary nitrogen, and repeated 24-h dietary recall methods
Validity biomarkers energy expenditure

Recently, the analysis of dietary patterns has emerged
as a possible approach to examining diet-disease relations.
High Frequency of Class 1 Integrons in Escherichia coli Isolated From Patients With Urinary Tract Infections in Yasuj, Iran
Integrons Urinary Tract Infections Multidrug Resistant Escherichia coli
2016/1/26
Background: Most urinary tract infections (UTI) are caused by Escherichia coli. Integrons have an important role in distributing antibiotic resistance genes among bacteria.
Objectives: The aim of thi...
Frequency of Peripheral Arterial Disease in Patients With Chronic Venous Insufficiency
Peripheral Vascular Disease Venous Insufficiency Risk Factors Ankle Brachial Index Leg Ulcer
2016/1/26
Background: It is estimated that about 15% (10% - 30% in most of the studies) of the total adult population has some aspects of the Chronic Venous Insufficiency (CVI). Frequency of the Peripheral Arte...
llele frequency for c.335 A>C polymorphisms in porcine ghrelin/obestatin prepropeptide gene and association analysis with performance traits in various pig breeds
quantitative trait locus GHRL pigs polymorphism genetic marker
2015/10/9
The allelic frequency of c.335A>C polymorphisms in the porcine ghrelin/obestatin prepropeptide (GHRL) gene was surveyed among six pig breeds and two subspecies of wild boars. The c.335C was the most f...
Expression of Heat Shock Proteins (HSPs) in Aged Skeletal Muscles Depends on the Frequency and Duration of Exercise Training
Aging multiple short-duration exercise training single long-duration exercise training heat shock protein
2015/8/28
However, the associated molecular mechanisms mediating
different types of exercise training-induced adaptations are not
yet completely understood. Therefore, the purpose of this study
was to inv...
