Dinitrogen Activation: A Novel Approach with P/B Intermolecular FLP.
J Phys Chem A
January 2025
School of Applied Science and Humanities, Haldia Institute of Technology, ICARE Complex, Haldia 721657, India.
This study explores the reactivity of a new intermolecular P/B frustrated Lewis pair in the context of dinitrogen activation through a push-pull mechanism. The ab initio molecular dynamics model known as atom-centered density matrix propagation plays a pivotal role in elucidating the weakly associated encounter complex. In-depth analysis, mainly through intrinsic reaction coordinate calculations, supports a single-step mechanism.

Introduction: Previous studies have revealed that perfectionism and identity development during adolescence are related. However, no longitudinal study has been conducted on the impact of perfectionism on identity development in adulthood. In the present study, we analyzed for the first time the longitudinal relationship between personal standards, an indicator of perfectionistic strivings, and concern over mistakes and doubts about actions, indicators of perfectionist concerns, and identity development in one of the most important yet least understood domains for adults, parental identity.

The development of deep learning algorithms has transformed medical image analysis, especially in brain tumor recognition. This research introduces a robust automatic microbrain tumor identification method utilizing the VGG16 deep learning model. Microscopy magnetic resonance imaging (MMRI) scans extract detailed features, providing multi-modal insights.

Soil microorganisms transform plant-derived C (carbon) into particulate organic C (POC) and mineral-associated C (MAOC) pools. While microbial carbon use efficiency (CUE) is widely recognized in current biogeochemical models as a key predictor of soil organic carbon (SOC) storage, large-scale empirical evidence is limited. In this study, we proposed and experimentally tested two predictors of POC and MAOC pool formation: microbial necromass (using amino sugars as a proxy) and CUE (by O-HO approach).

J Anim Ecol
January 2025
Section of Ecology, Department of Biology, University of Turku, Turku, Finland.
The hoarding behaviour of animals has evolved to reduce starvation risk when food resources are scarce, but effects of food limitation on survival of hoarding animals is poorly understood. Eurasian pygmy owls (Glaucidium passerinum) hoard small mammals and birds in natural cavities and nest boxes in late autumn for later use in the following winter. We studied the relative influence of the food biomass in hoards of pygmy owls on their over-winter and over-summer apparent survival.
