Quantifying the nutritional and income loss due to crop raiding in rural African subsistence farming community in South Africa

open access: yesJàmbá, 2021
Globally, crop damage by wildlife contributes to food insecurity through direct loss of food and income. We investigated the calories lost and potential economic impact of crop raiding to subsistence homesteads abutting the Hluhluwe Game Reserve and ...

All‐polymer solar cells with over 16% efficiency and enhanced stability enabled by compatible solvent and polymer additives

open access: yesAggregate, 2022
Considering the robust and stable nature of the active layers, advancing the power conversion efficiency (PCE) has long been the priority for all‐polymer solar cells (all‐PSCs). Despite the recent surge of PCE, the photovoltaic parameters of the state‐of‐

Study of Energy Loss Characteristics of a Shaft Tubular Pump Device Based on the Entropy Production Method

open access: yesEntropy, 2023
The unstable flow of a shaft tubular pump device (STPD) leads to energy loss, thereby reducing its efficiency. The aim of this study is to investigate the distribution pattern of energy loss in STPDs.

Event Plane Dependence of Jet-Hadron Correlations in Au–Au Collisions at √sNN = 200 GeV with the STAR Detector at RHIC

open access: yesProceedings, 2019
The phenomenon of jet quenching indicates that partons lose energy as they traverse the hot dense medium. By restricting a trigger jet in azimuth relative to the event plane, we are given another tool, which allows us to study the path length dependence ...
