Published in 2020 at "Solar Energy"

DOI: 10.1016/j.solener.2019.09.025

Abstract: Abstract Parabolic trough solar receivers are the key heat-collecting elements (HCEs) in parabolic trough collectors (PTCs). However, the HCEs emit considerable heat loss at high operating temperature, which exerts significantly negative impact on the thermal… read more here.

Published in 2023 at "Proceedings of the National Academy of Sciences of the United States of America"

DOI: 10.1073/pnas.2218142120

Abstract: The internal state of an animal, including homeostatic requirements, modulates its behavior. Negative energy balance stimulates hunger, thus promoting a range of actions aimed at obtaining food. While these survival actions are well established, the… read more here.

Published in 2021 at "Italian Journal of Animal Science"

DOI: 10.1080/1828051x.2021.1899855

Abstract: Negative energy balance (NEB) is an important risk factor for the dairy cow’s anoestrus. The purpose of the experiment is to screen out differentially expressed proteins (DEPs) in the follicular fl... read more here.

Published in 2019 at "Biology of Reproduction"

DOI: 10.1093/biolre/ioz175

Abstract: Abstract Metabolic demands of modern hybrid sows have increased over the years, which increases the chance that sows enter a substantial negative energy balance (NEB) during lactation. This NEB can influence the development of follicles… read more here.

Published in 2019 at "Physical Review D"

DOI: 10.1103/physrevd.99.026002

Abstract: Quantum states with negative energy densities have been long known to exist in quantum field theories. We explore the structure of such states for holographic theories using quantum information theory tools and show how certain… read more here.

Published in 2021 at "BMC Genomics"

DOI: 10.1186/s12864-021-07713-z

Abstract: Background In post-partum dairy cows, the energy needs to satisfy high milk production induces a status of more or less pronounced Negative Energy Balance (NEB). NEB associated with fat mobilization impairs reproductive function. In a… read more here.

Published in 2017 at "Journal of Animal Science and Biotechnology"

DOI: 10.1186/s40104-017-0224-y

Abstract: BackgroundAssociative data and some controlled studies suggest that the inflammatory cytokine tumor necrosis factor (TNF) α can induce fatty liver in dairy cattle. However, research demonstrating that TNFα is a necessary component in the etiology… read more here.

Published in 2020 at "Journal of dairy science"

DOI: 10.3168/jds.2019-17705

Abstract: The objective of this study was to determine how feeding behavior of dairy cows is altered in response to diet-induced negative energy balance, and if this response varies depending on dietary particle size distribution. Multiparous… read more here.

Published in 2020 at "Nutrients"

DOI: 10.3390/nu12040891

Abstract: The indisputable association between visceral adipose tissue (VAT) and cardiometabolic risk makes it a primary target for lifestyle-based strategies designed to prevent or manage health risk. Substantive evidence also confirms that liver fat (LF) is… read more here.
