The effectiveness of resistance exercises performed on stable and unstable surfaces in relation to torso activation

Baltic Journal of Health and Physical Activity, 2023
Introduction: Deep stabilization system (DSS) strength and endurance are crucial for injury prevention and athletic performance. Training surfaces can influence training outcomes; therefore, this study aimed to compare the impact of performing strength ...

Vision-based Anti-UAV Detection and Tracking [PDF]

arXiv, 2022
Unmanned aerial vehicles (UAV) have been widely used in various fields, and their invasion of security and privacy has aroused social concern. Several detection and tracking systems for UAVs have been introduced in recent years, but most of them are based on radio frequency, radar, and other media.

Observable dynamics and coordinate systems for automotive target tracking [PDF]

Proceedings of the IEEE Intelligent Vehicles Symposium (2009) 741-746, 2010
We investigate several coordinate systems and dynamical vector fields for target tracking to be used in driver assistance systems. We show how to express the discrete dynamics of maneuvering target vehicles in arbitrary coordinates starting from the target's and the own (ego) vehicle's assumed dynamical model in global coordinates.

Higher frequency of hamstring injuries in elite track and field athletes who had a previous injury to the ankle - a 17 years observational cohort study

Journal of Foot and Ankle Research, 2018
BackgroundInversion injury to the ankle and hamstring injuries are common problems in most sports. It is not known whether these injuries constitute a predisposing factor or a precursor of injury or re-injury of these anatomical locations.

A New Track Reconstruction Algorithm suitable for Parallel Processing based on Hit Triplets and Broken Lines [PDF]

, 2016
Track reconstruction in high track multiplicity environments at current and future high rate particle physics experiments is a big challenge and very time consuming. The search for track seeds and the fitting of track candidates are usually the most time consuming steps in the track reconstruction. Here, a new and fast track reconstruction method based

TROPHY: A Topologically Robust Physics-Informed Tracking Framework for Tropical Cyclones [PDF]

arXiv, 2023
Tropical cyclones (TCs) are among the most destructive weather systems. Realistically and efficiently detecting and tracking TCs are critical for assessing their impacts and risks. Recently, a multilevel robustness framework has been introduced to study the critical points of time-varying vector fields.

Lifetime Prevalence of Verbal, Physical, and Sexual Abuses in Young Elite Athletics Athletes

Frontiers in Sports and Active Living, 2021
To examine prevalence of verbal, physical, and sexual abuses in young elite athletes, a cross sectional questionnaire-based survey was conducted during the World Athletics under 20 World Championships.

The Importance of Lean Body Mass for the Rate of Force Development in Taekwondo Athletes and Track and Field Throwers

Journal of Functional Morphology and Kinesiology, 2018
The rate of force development (RFD) is vital for power athletes. Lean body mass (LBM) is considered to be an essential contributor to RFD, nevertheless high RFD may be achieved by athletes with either high or low LBM. The aim of the study was to describe

Tracking habitus across a transnational professional field [PDF]

Work, Employment and Society, 2015
The sociology of the professions has shied away from cross-national comparative work. Yet research in different professional jurisdictions emphasizes the transnational nature of professional fields. Further work is therefore needed that explores the extent to which transnational professional fields are characterized by unity or heterogeneity.
