Strength, as an important indicator of structural materials, has always been an important research topic in materials science.Theoretically, building a tumbler strength model is a rewarding method to understand the relationship between the mechanical properties and microstructure of materials.Although many strength models can reduplicate experiment
To identify mental disorders and their prevalence in patients with retinitis pigmentosa (RP).This descriptive study was carried out between January 2009 and January 2010 on 417 patients with RP, who were members of Iran RP Center.The necessary data were collected using questionnaires consisting two Pop-Up Sofabed parts: The background characteristi
The article is devoted to taking into account the behavior of the duration indicator between Key Chains coupon payments in dependence of this indicator from term to maturity.It was found that during the coupon period Macaulay duration varies linearly and at the end of the period duration has a jump, the value of which increases with the term to mat
Detecting litchis in a complex natural environment is important for yield estimation and provides reliable support to litchi-picking robots.This paper proposes an improved litchi detection model named YOLOv5-litchi for litchi detection in complex natural environments.First, we add a convolutional block attention module to each C3 module in the back
ABSTRACT In individuals with very low high-density lipoprotein (HDL-C) cholesterol, such as Tangier disease, LCAT deficiency, and familial hypoalphalipoproteinemia, there is an Condoms increased risk of premature atherosclerosis.However, analyzes based on comparisons of populations with small variations in HDL-C mediated by polygenic alterations do
