Rapid scavenging of avian carcasses in the desert Southwest: Implications for mortality surveys not associated with infrastructure

Wildlife Society Bulletin, EarlyView.
We placed 214 avian carcasses in a desert environment at locations not associated with infrastructure and monitored their removal by scavengers using camera traps. We found that 211 of the 214 carcasses were scavenged and median persistence time was 1.53 days. None of the predictor variables were informative of carcass persistence times.

Evaluation of the Sex and Species Distribution, Breeding, and Life Expectancy of Zoo‐Housed Chameleons

Zoo Biology, EarlyView.
ABSTRACT More than a third of the 202 identified chameleon species are classified as “vulnerable” or “critically endangered”. No data is available regarding the life expectancy of chameleons kept in zoos. The objectives of this study were to determine the sex and species distribution of chameleons kept in zoological institutions, and to assess their ...

Optimal Scheduling of Data Centre Integrated Energy Systems Considering Electric‐Thermal Demand Response Under Icing Uncertainty

Energy Internet, EarlyView.
ABSTRACT Extreme icing disasters increasingly undermine the reliability of integrated power and heat networks by causing line outages, supply shortages and sharp thermal load fluctuations. To address these challenges, this paper proposes a comprehensive optimisation framework that exploits the spatiotemporal flexibility of data centres for coordinated ...

Effect of Unit Cell Topology on Dielectric Properties of Periodic Lattice Materials Used for Functionally Graded Insulation

High Voltage, EarlyView.
ABSTRACT Periodic lattice material (PLM) is an innovative material system capable of rapidly and efficiently constructing functionally graded materials (FGMs). Among various PLM structures, triply periodic minimal surfaces (TPMS) exhibit numerous advantages, making TPMS‐based lattice materials a potential candidate to electrical FGMs.
