This study evaluated the validity of two wheelchair-mounted devices-the Cateye® and Wheeler-for monitoring wheelchair speed and distance traveled. Speed estimates were validated against a calibrated treadmill at speeds from 1.5 to 10 km/hr. Twenty-five wheelchair users completed a course of known distance comprising a sequence of everyday wheelchair activities. Speed estimate validity was very good (mean absolute percentage error ≤ 5%) for the Wheeleri at all speeds and for the Cateye at speeds >3 km/hr but not speeds <3 km/hr (mean absolute percentage error > 20%). Wheeleri distance estimates were good (mean absolute percentage error < 10%) for linear pushing activities and general maneuvering but poor for confined-space maneuvering. Cateye estimates were good for continuous linear propulsion but poor for discontinuous pushing and maneuvering (both general and confined space). Both devices provided valid estimates of speed and distance for typical wheelchair-based exercise activities. However, the Wheeleri provided more accurate estimates of speed and distance during typical everyday wheelchair activities.

Background: The study evaluated the relationship between balance function and skeletal muscle mass index (ASMI), physical function, and fatigue in children with chronic kidney disease (CKD).
Methods: A cross-sectional study of 83 children with CKD (stages 1-4, dialysis, transplant) and 71 healthy controls was conducted. Functional performance tests, including gait speed, 6-min walk distance (6MWD), five-repetition sit-to-stand (5RST), and timed up-and-go (TUG) tests, were administered.

Introduction: This study analyzed the impact of various overload conditions on sprint performance compared to free sprinting, aiming to identify the loading scenarios that most closely replicate the mechanics of unresisted sprints across the full acceleration spectrum. While velocity-based training methods have gained popularity, their applicability is limited to the plateau phase of sprinting.
Methods: To address this limitation, we employed cluster analysis to identify scenarios that best replicate the mechanical characteristics of free sprinting across various overload conditions.

As the size of the chemical industry increases, chemical accidents continue to occur as the handling volume of chemicals also increases. Currently, in the case of a chemical accident, the prediction of the scope of influence mainly analyzes the scope of the impact on a single substance in the accident and does not consider the scope of the decomposition and reaction products. Nitric acid, one of the many chemical accidents, produces nitrogen dioxide, which is harmful when decomposed.

Unlabelled: Dystrophinopathies - a group of hereditary X-linked neuromuscular diseases characterized by worsening fibrofatty degeneration of skeletal muscles, muscular weakness, low exercise tolerance, as well as orthopedic, cardiovascular and respiratory complications. Study of the effectiveness of physical medical rehabilitation in patients with neuromuscular diseases, evaluation of the influence of external and internal factors on functional capabilities and effectiveness of the conducted rehabilitation are highly relevant.
Objective: To evaluate the effectiveness of physical medical rehabilitation of patients with dystrophinopathies at the outpatient stages of the disease's course and the influence of anthropometric characteristics and functional status of patients' motor capabilities.

Sequencing-based Hi-C technology has been widely used to study the three-dimensional structure of chromatin. More recently, the development of single-cell Hi-C technology has enabled the study of chromatin structural variations between individual cells. However, single-cell Hi-C data are often highly sparse, necessitating the use of imputation algorithms to address insufficient sampling.
