Compton scattering is a key process shaping spectra formation and accretion flow dynamics in accreting strongly magnetized neutron stars. A strong magnetic field affects the cross section makes it dependent on photon energy, momentum, polarization state. Using Monte Carlo simulations, we investigate statistical features of polarized X-ray radiation field. Our analysis focused gas behaviour well...
Abstract Motivation and objective Obstructive sleep apnea (OSA) is a disorder identified in nearly 10% of middle-aged people, which deteriorates the normal functioning human organs, notably that heart. Furthermore, untreated OSA associated with increased hypertension, diabetes, stroke, cardiovascular diseases, thereby increasing mortality risk. Therefore, early identification significant intere...
This paper describes a representation of the dynamics of human walking action for the purpose of person identification and classification by gait appearance. Our gait representation is based on simple features such as moments extracted from video silhouettes of human walking motion. We claim that our gait dynamics representation is rich enough for the task of recognition and classification. The...
We study a dynamic coordination process in which agents are uncertain about the actions of their fellow agents, and anticipate strategically relevant information. Because of the uncertainty and learning, (ir)reversibility of actions has important strategic consequences. We find that the reversibility option can either enhance or hamper efficient coordination, and we characterize the direction o...
Huntington's disease (HD) is a congenital, progressive, neurodegenerative disorder characterized by cognitive, motor, and psychological disorders. Clinical diagnosis of HD relies on the manifestation of movement abnormalities. In this study, we introduce a mathematical method for HD detection using step spacing. We used 16 walking signals as control and 20 walking signals as HD. We took a s...
