Neutron Induced reactions on different target nuclei have get impact on many nuclear basic sciences and applications. Due to the lack of literature available experimental data for many targets, empirical formulae for the (n, p) reactions cross section on different targets and different incident neutron energies are formulated. The formulae are used for calculation of excitation functions for target isotopes having atomic numbers in the range from 21 to 51 and neutron energies from 20 MeV down to respective threshold energy of each reaction. The results are compared to the existing experimental results as well as the TENDL-2019 database values.

This study employs quantum chemical computational methods to predict the spectroscopic properties of fluorescent probes 2,6-bis(2-benzimidazolyl)pyridine (BBP) and ()-3-(2-(1-benzo[]imidazol-2-yl)vinyl)-9-(2-(2-methoxyethoxy)ethyl)-9-carbazole (BIMC). Using time-dependent density functional theory (TDDFT), we successfully predicted the fluorescence emission wavelengths of BBP under various protonation states, achieving an average deviation of 6.0% from experimental excitation energies.

Sigmoid functions are widely used for the description of viscoelastic material properties of asphalt mixtures. Unfortunately, there are still no known closed functions for describing connections among model parameters in the time and the frequency domains. In most cases, complicated interconversion methods are applied for the conversion of viscoelastic material properties.

Alzheimer's disease (AD) is gradually increasing in prevalence and the complexity of its pathogenesis has led to a lengthy process of developing therapeutic drugs with limited success. Faced with this challenge, we proposed using a state-of-the-art drug screening algorithm to identify potential therapeutic compounds for AD from traditional Chinese medicine formulas with strong empirical support. We developed four deep neural network (DNN) models for AD drugs screening at the disease and target levels.

Importance: Using albumin-adjusted calcium is commonly recommended for for measuring calcium, but with little empirical evidence to support the practice.
Objective: To assess the correlation between total calcium measurements (with or without adjustment) vs the ionized calcium level as a reference standard.
Design, Setting, And Participants: This was a population-based cross-sectional study in the province of Alberta, Canada, including adults tested for serum total calcium and ionized calcium simultaneously between January 1, 2013, and October 31, 2019.
