DOI: 10.1016/j.anucene.2019.06.042
Abstract: Abstract Loading Pattern Optimization (LPO) is an extremely important issue for the safe and economic operation at nuclear power plants because the core configuration affects many of the neutronic and thermal-hydraulic parameters (NTPs) of the… read more here.

DOI: 10.1016/j.cej.2020.124623
Abstract: Abstract Thermoregulating textiles (or protective clothing) are highly demanded for both human health and labor productivity especially in hot working environments. It is challenging to balance wearability and thermal insulating property as they usually demand… read more here.

DOI: 10.1016/j.ecolind.2021.108245
Abstract: Abstract Climate warming and associated physical and biological changes will likely force widespread species redistribution, particularly in polar environments. However, tracking such distributional shifts is difficult. The dietary habits of apex predators, like polar bears… read more here.

DOI: 10.1038/s41558-020-0818-9
Abstract: Polar bears ( Ursus maritimus ) require sea ice for capturing seals and are expected to decline range-wide as global warming and sea-ice loss continue 1 , 2 . Estimating when different subpopulations will likely… read more here.

DOI: 10.1098/rsif.2022.0466
Abstract: Microscopic papillae on polar bear paw pads are considered adaptations for increased friction on ice/snow, yet this assertion is based on a single study of one species. The lack of comparative data from species that… read more here.

High contributions of sea ice derived carbon in polar bear (Ursus maritimus) tissue
Sign Up to like & getrecommendations! Published in 2018 at "PLoS ONE"
DOI: 10.1371/journal.pone.0191631
Abstract: Polar bears (Ursus maritimus) rely upon Arctic sea ice as a physical habitat. Consequently, conservation assessments of polar bears identify the ongoing reduction in sea ice to represent a significant threat to their survival. However,… read more here.

DOI: 10.3390/genes9090445
Abstract: The sequencing of ancient DNA samples provides a novel way to find, characterize, and distinguish exogenous genomes of endogenous targets. After sequencing, computational composition analysis enables filtering of undesired sources in the focal organism, with… read more here.

A real-time PCR assay to accurately quantify polar bear DNA in fecal extracts
Sign Up to like & getrecommendations! Published in 2020 at "PeerJ"
DOI: 10.7717/peerj.8884
Abstract: DNA extracted from fecal samples contains DNA from the focal species, food, bacteria and pathogens. Most DNA quantification methods measure total DNA and cannot differentiate among sources. Despite the desirability of noninvasive fecal sampling for… read more here.
