The Relationship Between Sleep Quality and Shooting Accuracy in Female Archers: A Cross-Sectional Study

Precision sports such as archery require sustained attention, fine motor control, and technical consistency, all of which may be influenced by sleep quality. This cross-sectional study aimed to examine the association between sleep quality and shooting accuracy in female archers...

Comparative Remineralization Efficacy of Different Physical Forms of Chitosan in a Newly Developed Olive Leaf Extract-Containing Artificial Saliva

Plant-derived bioactive compounds and natural biopolymers are increasingly investigated as components of multifunctional remineralization systems. This in vitro study compared the remineralization efficacy of chitosan film, gel, and solution on bleached human enamel within an oli...

A Spectral Projected Gradient Algorithm for an Elliptic Inverse Coefficient Problem with a Robin Boundary Condition

An inverse problem of recovering a lower-order coefficient in a second-order elliptic equation with a Robin boundary condition is considered. Uniqueness of the inverse problem solution is established. For the numerical solution of the inverse problem, a difference scheme is const...

Field-validated modelling of coupler forces during freight-train start-up on a steep gradient

Restarting a heavy freight train on a steep gradient produces transient tensile forces because locomotive tractive effort is transmitted through sequential coupler-slack closure and nonlinear draft-gear loading. This study develops a longitudinal multi-body model in MSC Adams for...

Evaluation of the Diagnostic Performance of Prenatal Screening Markers for Down Syndrome in the Turkistan Region

Background: The Turkestan region is one of the regions with a high birth rate; therefore, analysis of the effectiveness of an early detection system for chromosomal abnormalities in this region is important for practical healthcare. Objective: To evaluate the diagnostic potential...

Radiographic Evaluation Of The Success Of Root Canal Treatment In Mandibular Premolars: A Retrospective Cross-Sectional Study

Background and Aim: Radiographic assessment is essential forevaluating the technical quality of root canal fillings and periapicalstatus after root canal treatment (RCT). This retrospective crosssectionalstudy assessed the radiographic quality of RCT in mandibularpremolars using...

The relationship between the uric acid to prealbumin ratio and frailty, muscle strength, and malnutrition risk in older geriatric outpatients: a retrospective cross-sectional study

Frailty, sarcopenia, and malnutrition are common in older adults; however, simple biomarkers reflecting both inflammatory and nutritional status remain limited. We aimed to evaluate the relationship between the uric acid-to-prealbumin ratio (UPR) and frailty, muscle strength, and...

Assessment of the Dissipative Properties of Viscoelastic Hollow Cylindrical Bodies with Filler During the Propagation of Natural Waves

Searching by numerical simulation for structures with optimal damping properties among viscoelastic hollow cylindrical bodies with a filler is usually associated with a large amount of computation. Formulating the mechanical problem as one of natural vibrations and natural wave p...

Teaching methodology for the course “Computer Methods in Physics” for prospective physics teachers based on adaptive technologies

Contemporary teacher education requires instructional approaches that can respond to heterogeneous levels of digital competence, subject knowledge, and learning pace among prospective teachers. This study examines a teaching methodology for the course “Computer Methods in Physics...
