Spatio‐temporal changes in chimpanzee density and abundance in the Greater Mahale Ecosystem, Tanzania

open access: yesEcological Applications, Volume 32, Issue 8, December 2022., 2022
Abstract Species conservation and management require reliable information about animal distribution and population size. Better management actions within a species' range can be achieved by identifying the location and timing of population changes. In the Greater Mahale Ecosystem (GME), western Tanzania, deforestation due to the expansion of human ...

Nitrogen‐Rich Oxetanes Based on the Combination of Azides and Tetrazoles

open access: yesEuropean Journal of Organic Chemistry, Volume 26, Issue 1, January 2, 2023., 2023
Several new energetic oxetane derivatives with higher nitrogen contents than previously reported in the literature were synthesized and characterized. An azide group and a tetrazole moiety were introduced into the starting material oxetan‐3‐one to obtain a 3‐disubstituted oxetane.

Influence of geometrical manufacturing tolerances on lithium‐ion battery performance

open access: yesInternational Journal of Energy Research, Volume 46, Issue 15, Page 23824-23838, December 2022., 2022
The influence of electrode coating thickness, calendaring and electrode cutting tolerance on lithium‐ion battery capacity, energy, resistance and voltage relaxation is investigated through a numerical model. Electrode cutting tolerance has the largest affect upon cell performance characteristics, with calendaring tolerance predominantly affecting the ...

Modelling interactions between waves and diffused interfaces

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 95, Issue 2, Page 215-241, February 2023., 2023
When simulating multiphase compressible flows using the diffuse‐interface methods, important issues arise during the interaction of waves with diffused interfaces. A solution is to use a pressure‐disequilibrium model with finite, instead of infinite, pressure‐relaxation rate.

Neuropsychiatric symptoms associated multimodal brain networks in Alzheimer's disease

open access: yesHuman Brain Mapping, Volume 44, Issue 1, Page 119-130, January 2023., 2023
Neuropsychiatric symptoms (NPS)‐associated multimodal pattern spatially involves frontal‐subcortical limbic circuits, which significantly associated with cognitive performance and progression. Different frontal‐subcortical limbic circuit regions suffer different pathogenic mechanisms in Alzheimer's disease subjects concomitant with NPS.
