Commissioning evaluation of a deviceless 4DCT scanner
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background The utilization of four‐dimensional computed tomography (4DCT) for radiation therapy has not seen major advances to the method of data binning since shortly after inception. Recently there is increased interest in the utilization of an alternative binning method rather than more established techniques.

On amplitude zeros at threshold
, 1992 The occurrence of zeros of 2 to n amplitudes at threshold in scalar theories is studied. We find a differential equation for the scalar potential, which incorporates all known cases where the 2 to n amplitudes at threshold vanish for all sufficiently ...

Design and validation of a novel dosimetry phantom for motion management audits
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Background We present a novel phantom design for conducting end‐to‐end dosimetry audits for respiratory motion management of two anatomical treatment sites. The design enables radiochromic film measurements of the dose administered to the target throughout the respiratory cycle (motion‐included) and the dose delivered to the time‐averaged ...

Models of adaptation of the milking machines systems
BIO Web of Conferences, 2018 Two systems of milking machines were considered - biotechnical and vacuum. Methodology for estimation of efficiency of the "machine-animal" biotechnical system was worked out. The dependences of the efficiency parameters of the technical system operation

Focal muscle vibration: evaluation of physical properties and his applications
Senses and Sciences, 2014 Vibration is the sensation produced by sinusoidal oscillation of objects placed against the skin. The vibratory frequency is signaled bythe frequency of action potentials fired by the sensory nerves and the total number of active sensory nerves is ...

Journal of High Energy Physics, 2022 Abstract Celestial holography provides a promising avenue to studying bulk scattering in flat spacetime from the perspective of boundary celestial conformal field theory (CCFT). A key ingredient in connecting the two sides is the celestial amplitude, which is given by the Mellin transform of momentum space scattering amplitude in ...
