The nuclear physics of neutron stars [PDF]

AIP Conference Proceedings, 2014
Neutron stars—compact objects with masses similar to that of our Sun but radii comparable to the size of a city—contain the densest form of matter in the universe that can be probed in terrestrial laboratories as well as in earth- and space-based observatories. The historical detection of gravitational waves from a binary neutron star merger has opened

Five‐year evaluation of linear accelerator‐based SRS platform isocentricity

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Linear accelerator (LINAC)‐based stereotactic radiosurgery (SRS) has become a mainstay in the management of intracranial tumors. However, the high fractional doses and sharp gradients used in SRS place heavy demands on geometric accuracy.

Verification of daily dose recalculation accuracy for an adaptive radiation therapy monitoring tool in helical tomotherapy for nasopharyngeal carcinoma

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose PreciseART, an adaptive radiation therapy (ART) software for helical tomotherapy (HT), was integrated into the Precision treatment planning system (Accuray, Inc., Sunnyvale, CA). It supports automatic monitoring of dose variations to both the target and organs at risk (OARs) throughout the treatment course.

Fundamental physics studies in time domain and multi-messenger astronomy

Frontiers in Astronomy and Space Sciences
The era of ime domain and multi-messenger astronomy is not only leading to the development of a much broader set of detectors and instruments for astrophysical observations, but is also providing the means for astronomy to tie directly to cutting-edge ...

Electroweak Probes and Nuclear Effective Field Theory [PDF]

arXiv, 2001
There is growing interest in nuclear physics applications of effective field theory. I give a brief account of some of the latest developments in this area. I also describe interplay between this new approach and the traditional nuclear physics approach.

Electro and gamma nuclear physics in Geant4

, 2003
Adequate description of electro and gamma nuclear physics is of utmost importance in studies of electron beam-dumps and intense electron beam accelerators. I also is mandatory to describe neutron backgrounds and activation in linear colliders.

Calibration and volunteer testing of a prototype contactless respiratory motion detection system based on laser tracking

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose The goal of this study was to assess the feasibility of a cost‐effective prototype of a laser‐based respiratory motion detection system utilizing a Leuze LDS for breath monitoring through calibration and volunteer tests. Methods This study was performed using the Anzai AZ‐773 V and computerized imaging reference systems (CIRS) motion ...

Application of Atomic Spectroscopy of Trapped Radioactive Ions in Nuclear Physics

Atoms
A review is given of precision measurements of hyperfine constants and nuclear g-factors measured with ions confined in ion traps. The nuclear physics observables which can be extracted from these types of measurements are discussed.

Optimization of target grouping in distributive stereotactic radiosurgery using the excel evolutionary solver

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Distributive stereotactic radiosurgery (dSRS) is a form of fractionation where groups of metastases are treated with a full single‐fraction dose on different days. The challenge with dSRS is determining optimal target groupings to maximize the distance between targets treated in the same fraction.
