Transgressing the horizons: Time operator in two-dimensional dilaton gravity [PDF]

, 2006
We present a Dirac quantization of generic single-horizon black holes in two-dimensional dilaton gravity. The classical theory is first partially reduced by a spatial gauge choice under which the spatial surfaces extend from a black or white hole ...

Comment on the “asymmetric variation of a finite mass harmonic like oscillator”

Results in Physics, 2022
The paper “asymmetric variation of finite mass harmonic like oscillator” in the Results Phys 19 (2020) 103335, contains a sign mistake in the dynamical equation used. This, in turn, affects the equations and results that follow.

Numerical properties of staggered quarks with a taste-dependent mass term [PDF]

, 2012
The numerical properties of staggered Dirac operators with a taste-dependent mass term proposed by Adams [1,2] and by Hoelbling [3] are compared with those of ordinary staggered and Wilson Dirac operators.

Integrated massive vertex operator in pure spinor formalism

Journal of High Energy Physics, 2018
We construct the integrated vertex operator for the first massive states of open superstrings with (mass)2 = 1/α ′ in the pure spinor formalism of the superstring theory. This vertex operator is expressed in terms of the ten dimensional N = 1 $$ \mathcal{

Exact NLO matching and analyticity in b → sℓℓ

Journal of High Energy Physics, 2020
Exclusive rare decays mediated by b → sℓℓ transitions receive contributions from four-quark operators that cannot be naively expressed in terms of local form factors. Instead, one needs to calculate a matrix element of a bilocal operator.

Removal of instabilities of the higher derivative theories in the light of antilinearity

European Physical Journal C: Particles and Fields, 2021
Theories with higher derivatives involve linear instabilities in the Hamiltonian commonly known as Ostrogradski ghosts and can be viewed as a very serious problem during quantization.

An analytic study of the off-diagonal mass generation for Yang-Mills theories in the maximal Abelian gauge [PDF]

, 2004
We investigate a dynamical mass generation mechanism for the off-diagonal gluons and ghosts in SU(N) Yang-Mills theories, quantized in the maximal Abelian gauge. Such a mass can be seen as evidence for the Abelian dominance in that gauge.

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Semi-Markov Model of MASS Voyage [PDF]

TransNav
The paper presents the readiness/safety model for the sea voyage of Maritime Autonomous Surface Ship (MASS), based on Semi-Markov process. The states of MASS during the voyage were defined as triplets of intentional type of MASS operations, reliability ...
