Land-Greening Hotspot Changes in the Yangtze River Economic Belt during the Last Four Decades and Their Connections to Human Activities

open access: yesLand, 2022
The spatial patterns of the normalized difference vegetation index (NDVI) changes in the Yangtze River Economic Belt (YREB) and their potential causes during the last four decades remain unclear.

Eigenstrain modelling of residual stress generated by arrays of Laser Shock Peeing shots and determination of the complete stress field using limited strain measurements [PDF]

open access: yes, 2012
This paper presents a hybrid explicit finite element (FE) /eigenstrain model for predicting the residual stress generated by arrays of adjacent/overlapping laser shock peening (LSP) shots where the use of a completely explicit FE analysis may be ...

A Novel Lifetime Model With A Bathtub-Shaped Hazard Rate: Properties & Applications

open access: yesJournal of Applied Science and Engineering, 2022
A novel three-parameter lifetime model called the Marshall Olkin power Ailamujia (MOPA) distribution is developed. The statistical qualities and reliability characteristics of the proposed model are examined, including moment, generating function ...

A review of residual stress analysis using thermoelastic techniques

open access: yes, 2009
Thermoelastic Stress Analysis (TSA) is a full-field technique for experimental stress analysis that is based on infra-red thermography. The technique has proved to be extremely effective for studying elastic stress fields and is now well established.

Comparison of joining efficiency and residual stresses in laser and laser hybrid welding [PDF]

open access: yes, 2011
Laser welding is a high energy density process, which can produce welds with less energy input and thereby lower residual stress generation compared to arc welding processes.

Analysis of residuating logic programs

open access: yesThe Journal of Logic Programming, 1995
Summary: Residuation is an operational mechanism for the integration of functions into logic programming languages. The residuation principle delays the evaluation of functions during the unification process until the arguments are sufficiently instantiated.

Estimation of genetic variation in residual variance in female and male broiler chickens [PDF]

open access: yes, 2008
In breeding programs, robustness of animals and uniformity of end product can be improved by exploiting genetic variation in residual variance. Residual variance can be defined as environmental variance after accounting for all identifiable effects.

GC–MS/MS–based multiresidue pesticide analysis in mealworm (Tenebrio molitor) larvae: Optimization of standard QuEChERS-based method to minimize matrix effects

open access: yesFood Chemistry: X
Given the unsuitability of the standard quick, easy, cheap, effective, rugged, and safe (QuEChERS)-based method for multiresidue pesticide analysis in mealworm larvae due to their complex composition and high lipid content, we established a gas ...

Analysis on long-range residue-residue communication using molecular dynamics [PDF]

open access: yesProteins: Structure, Function, and Bioinformatics, 2014
We investigated the possibility of inter-residue communication of side chains in barstar, an 89 residue protein, employing mutual information theory. The normalized mutual information (NMI) of the dihedral angles of the side chains was obtained from all-atom molecular dynamics simulations.
