POINTS -- Playful objects for inclusive, personalized movement games [PDF]
arXiv, 2019 Promoting exercise and promoting fun in sport and activity is a common goal of schools. However, children and adolescents do not exercise enough, which can favor a number of chronic illnesses. Exercise and sports often require coordination of visual perception and reaction, which is an additional barrier for visually impaired (blind and partially ...

The impact of physical exertion on the level of back pain
Journal of Education, Health and SportIntroduction: Physical activity is an inherent factor in a healthy lifestyle. Regular exercise allows you to maintain fitness with age and allows for proper functioning of everyday life. The aim of the study was to assess the impact of physical effort on the level of back pain. Materials and methods: The study involved 113 people who were assigned to

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose To investigate the feasibility of adapting a commercial prostate biopsy system for transrectal ultrasound (TRUS)‐guided hybrid gynecological (GYN) high‐dose‐rate (HDR) brachytherapy (BT). Leveraging 3D‐TRUS and MR image fusion, the prototype system aims to improve real‐time needle placement accuracy.

Fluctuations and Long-Term Stability: from Coherence to Chaos [PDF]
arXiv, 2005 Exerting fluctuations is a part of our daily life: traffic noise, heartbeat, opinion poll, currency exchange rate, electrical current, chemical reactions - they all permanently fluctuate. One of the most important questions is why the systems that exert fluctuations stay long-term stable. Is there any general functional relation that provides long-term

Machine stability and dosimetry for ultra‐high dose rate FLASH radiotherapy human clinical protocol
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The FLASH effect, induced by ultra‐high dose rate (UHDR) irradiations, offers the potential to spare normal tissue while effectively treating tumors. It is important to achieve precise and accurate dose delivery and to establish reliable detector systems, particularly for clinical trials needed to help the clinical transfer of FLASH‐

Casimir Torque for a Perfectly Conducting Wedge: A Canonical Quantum Field Theoretical Approach [PDF]
IJTP 44 (2005) 229 (including the Erratum published in 2007), 2013 The torque density per unit height exerted on a perfectly conducting wedge due to the quantum vacuum fluctuations (the Casimir torque) is obtained. A canonical quantum field theoretical approach with the method of calculating vacuum-to-vacuum propagator (Green function) [1] is used.

Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background Tumor segmentation is crucial for lung disease diagnosis and treatment. Most existing deep learning‐based automatic segmentation methods rely on manually annotated data for network training. Purpose This study aims to develop an unsupervised tumor segmentation network smic‐GAN by using a similarity‐driven generative adversarial ...

Vain is the pursuit of gravity waves [PDF]
arXiv, 1999 The modern apparatuses for the detection of the gravity waves are devised with the purpose to exploit the geodesic deviation generated by them. But the pseudo energy-momentum of these waves cannot exert any physical action on the apparatuses.
