Econometric predictive model for assessing the functional state of students during the examination period: a cross-sectional exploratory pilot study
Published 2023-10-01“…Mathematical modeling is widely used in medicine to analyze the body systems in terms of their structure, work and interrelations. The present study investigates factors associated with the adaptation potential of the cardiovascular system, develops multiple regression models for the dependence of the adaptive potential on these factors, and compares the significance of the linear model with non-linear ones. …”

The competition between self-seeding and specific nucleation in crystallization of long-chain branched polypropylene
Published 2023-11-01“…The main purpose of this work is to present the effect of long-chain branching and specific α-nucleation on the optical properties, crystallization and supermolecular structure of polypropylene (PP). Commercially available α-nucleating/clarifying agent 1,3;2,4-bis(3,4-dimethylbenzylidene)sorbitol (Millad 3988) was mixed into linear PP and long-chain branched PP (LCB-PP) in the concentration of 0.2 wt%. …”

A Time-Variant Model for Chloride Ion Diffusion Coefficient in Concrete
Published 2025-06-01“…When the chloride ion concentration within concrete reaches a certain threshold, it triggers corrosion of the reinforcing steel bars, severely compromising the durability of reinforced concrete structures. Accurately assessing how the chloride ion concentration in concrete evolves over time is crucial for ensuring structural safety and evaluating the remaining service life. …”

Strategies for regulating energy storage characteristics of relaxor ferroelectric films
Published 2025-03-01“…The analysis indicates although element doping is easy to achieve, its regulatory scope is limited, and the improvement of the energy storage characteristics relaxor ferroelectric films is not ideal. The composite structure, by using the approximate linear superposition of the related properties of two or more materials, has further improved the energy storage characteristics. …”

QSPR and QSTR analysis to explore pharmacokinetic and toxicity properties of antifungal drugs through topological descriptors
Published 2025-05-01“…In theoretical chemistry, a chemical molecule is converted into an isomorphic molecular graph, represented as G (V, E) by considering atom set V as vertices and bond set E as edges. Quantitative structure–activity/property/toxicity relationships (QSAR, QSPR, QSTR) modelling is a widely recognized discipline that correlates physicochemical and molecular descriptors with a drug’s bioactivity to predict its standard pharmacological properties. …”
