Published in 2022 at "Advanced Science"

DOI: 10.1002/advs.202103735

Abstract: Metal halide perovskite scintillators encounter unprecedented opportunities in indirect ionizing radiation detection due to their high quantum yields. However, the long scintillation lifetime of microseconds upon irradiation, known as the afterglow phenomenon, obviously limits their… read more here.

Published in 2019 at "Ecosphere"

DOI: 10.1002/ecs2.2790

Abstract: Existing projections of climate change impacts focus primarily on direct abiotic impacts on individuals and populations. However, these models often ignore species interactions, which are vital for determining community composition and structure. To evaluate both… read more here.

Published in 2022 at "Journal of Leukocyte Biology"

DOI: 10.1002/jlb.5ru0222-082r

Abstract: Vascular endothelial growth factor‐A (VEGF) is the predominant angiogenic factor that is expressed in solid tumors. Besides its critical function in mediating tumor angiogenesis, multiple studies have demonstrated that VEGF also contributes to tumor immunosuppression.… read more here.

Published in 2025 at "Medical Physics"

DOI: 10.1002/mp.18108

Abstract: In contrast‐enhanced digital mammography (CEDM) and contrast‐enhanced digital breast tomosynthesis (CEDBT), low‐energy (LE) and high‐energy (HE) images are acquired after injection of iodine contrast agent. Weighted subtraction is then applied to generate dual‐energy (DE) images,… read more here.

Published in 2020 at "Sustainable Development"

DOI: 10.1002/sd.2123

Abstract: The effect of national culture on country environmental performance has received attention during the past few years. However, previous studies considered a subset of cultural dimensions, focused on diverse environmental performance measures, provided contrasting results,… read more here.

Published in 2019 at "Molecular Genetics and Genomics"

DOI: 10.1007/s00438-019-01588-2

Abstract: Traditional single-trait genetic analyses, such as quantitative trait locus (QTL) and genome-wide association studies (GWAS), have been used to understand genotype–phenotype relationships for egg traits in chickens. Even though these techniques can detect potential genes… read more here.
