Weibull Distribution and the multiplicity moments in $pp\,(p\bar{p})$ collisions [PDF]
A higher moment analysis of multiplicity distribution is performed using the Weibull description of particle production in $pp\,(p\bar{p})$ collisions at SPS and LHC energies. The calculated normalized moments and factorial moments of Weibull distribution are compared to the measured data.

Impact of flexible noise control (FNC) image processing parameters on portable chest radiography
Abstract There is a lack of understanding in the performance of flexible noise control (FNC) processing, which is used in digital radiography on a scanner vendor and has four parameters each involving multiple options. The aim of this study was to investigate the impact of FNC on portable chest imaging. An anthropomorphic chest phantom was imaged using

Nonadiabatic Induced Dipole Moment by High Intensity Femtosecond Optical Pulses [PDF]
Nonadiabtic dressed states and nonadiabatic induced dipole moment in the leading order of nonadiabaticity is proposed. The nonadiabatic induced dipole moment is studied in the femtosecond time domain.

Volume staging for arteriovenous malformation SRS treatment using VMAT
Abstract Volume staging involves dividing the target volume into smaller parts and treating each part separately. In this study, the feasibility of volume‐staged stereotactic radiosurgery (VS‐SRS) on a linear accelerator using volumetric modulated arc therapy (VMAT) and a frameless patient positioning system is investigated.

Abstract This study aimed to evaluate the clinical beam commissioning results and lateral penumbra characteristics of our new pencil beam scanning (PBS) proton therapy using a multi‐leaf collimator (MLC) calculated by use of a commercial Monte Carlo dose engine.

Matter-parity as a residual gauge symmetry: Probing a theory of cosmological dark matter
We discuss a non-supersymmetric scenario which addresses the origin of the matter-parity symmetry, PM=(−1)3(B−L)+2s, leading to a viable Dirac fermion dark matter candidate.

formulation of the first principles in Physics I 7 in light of the notion of generation
In the present work we are interested in analyzing how Aristotle formulates the principles of physics from the notion of generation. Our thesis is that Physics I 7 is the “moment” of euporia that closes a process beginning in 1-2 with the ...

Abstract Purpose The aim of this work was to evaluate the SunCHECK PerFRACTION, the software for in vivo monitoring using EPID images. Materials/Methods First, the PerFRACTION ability to detect errors was investigated simulating two situations: (1) variation of LINAC output and (2) variation of the phantom thickness.

Electric dipole moments and the search for new physics
Static electric dipole moments of nondegenerate systems probe mass scales for physics beyond the Standard Model well beyond those reached directly at high energy colliders. Discrimination between different physics models, however, requires complementary searches in atomic-molecular-and-optical, nuclear and particle physics.

Electric dipole moments in a leptoquark scenario for the B-physics anomalies [PDF]
Abstract Vector leptoquarks can address the lepton flavor universality anomalies in decays associated with the b → cℓν and b → sℓℓ transitions, as observed in recent years. While not required to explain the anomalies, these leptoquarks generically yield new sources of CP violation.
