Treatment planning with a 2.5 MV photon beam for radiation therapy

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose The shallow depth of maximum dose and higher dose fall‐off gradient of a 2.5 MV beam along the central axis that is available for imaging on linear accelerators is investigated for treatment of shallow tumors and sparing the organs at risk (OARs) beyond it.

Accuracy of patient dose estimation in cone beam computed tomography in breast irradiation by size‐specific dose estimates with position correction

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract This study aims to investigate the effects of the position correction of size‐specific dose estimates (SSDE) on patient dose estimation in cone beam computed tomography (CBCT). The relationship between the phantom position and absorbed dose in the right breast was studied using optically stimulated luminescence dosimeters and a simulated human

Coincidence of a high-fluence blazar outburst with a PeV-energy neutrino event [PDF]

Nature Physics, 2016
The astrophysical sources of the extraterrestrial, very high-energy neutrinos detected by the IceCube collaboration remain to be identified. Gamma-ray (γ-ray) blazars have been predicted to yield a cumulative neutrino signal exceeding the atmospheric ...

Nonstationary flood coincidence risk analysis using time-varying copula functions

Scientific Reports, 2020
The coincidence of flood flows in a mainstream and its tributaries may lead to catastrophic floods. In this paper, we investigated the flood coincidence risk under nonstationary conditions arising from climate changes.

Coincidence velocity map imaging using Tpx3Cam, a time stamping optical camera with 1.5 ns timing resolution. [PDF]

Review of Scientific Instruments, 2017
We demonstrate a coincidence velocity map imaging apparatus equipped with a novel time-stamping fast optical camera, Tpx3Cam, whose high sensitivity and nanosecond timing resolution allow for simultaneous position and time-of-flight detection.

A case of a double variant of the arterial system in the upper extremity: Arteria brachialis accessoria et arteria comitans nervi mediani [PDF]

Archives of Biological Sciences, 2011
A thorough knowledge of arteries of the upper extremity is necessary for catheterization, graft harvesting, shunt application, and Astrup’s examination. Coincidences of two different variants are rather rare.

The clinical spectrum of SMA‐PME and in vitro normalization of its cellular ceramide profile

Annals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 1941-1952, December 2022., 2022
Abstract Objective The objectives of this study were to define the clinical and biochemical spectrum of spinal muscular atrophy with progressive myoclonic epilepsy (SMA‐PME) and to determine if aberrant cellular ceramide accumulation could be normalized by enzyme replacement.

Overlap coincidence to strong coincidence in substitution tiling dynamics [PDF]

European Journal of Combinatorics 39C (2014), pp. 233-243, 2014
Overlap coincidence is an equivalent criterion to pure discrete spectrum of the dynamics of self affine tilings. In the case of one dimension, strong coincidence on m letter irreducible substitution has been introduced in Dekking (1978) and Arnoux and Ito (2001) which implies that the system is metrically conjugate to a domain exchange. However being a

A scalable multi-photon coincidence detector based on superconducting nanowires [PDF]

Nature Nanotechnology, 2017
Coincidence detection of single photons is crucial in numerous quantum technologies and usually requires multiple time-resolved single-photon detectors. However, the electronic readout becomes a major challenge when the measurement basis scales to large ...

Prophetic Visions, Quality Serials: Twin Peaks’ new mode of storytelling

Series. International journal of tv serial narratives, 2015
Following the April 1990 debut of Twin Peaks on ABC, the vision - a sequence of images that relates information of the narrative future or past – has become a staple of numerous network, basic cable and premium cable serials, including Buffy the Vampire ...
