Radiative B decay spectrum: DGE at NNLO. [PDF]

open access: yes, 2010
We compute the differential ¯B → Xsγ decay width in the Standard Model as a function of the photon energy using Dressed Gluon Exponentiation (DGE).

Progress in computing inclusive B decay spectra. [PDF]

open access: yes, 2006
We review the progress in the QCD calculation of inclusive decay spectra. It was recently shown that the inherent infrared finiteness of inclusive spectra extends beyond the level of logarithms.

Reaction–diffusion with stochastic decay rates [PDF]

open access: yesPhysical Chemistry Chemical Physics, 2017
Microscopic physical and chemical fluctuations in a reaction–diffusion system lead to anomalous chemical kinetics and transport on the mesoscopic scale. Emergent non-Markovian effects lead to power-law reaction times and localization of reacting species.

Precision long-term measurements of beta-decay-rate ratios in a controlled environment

open access: yesPhysics Letters B, 2017
We report on measurements of relative beta-decay rates of Na-22, Cl-36, Co-60, Sr-90, Cs-137 monitored for more than one year. The radioactive samples are mounted in an automated sample changer that sequentially positions the five samples in turn, with ...

Degradation modeling of water environmental DNA: Experiments on multiple DNA sources in pond and seawater

open access: yesEnvironmental DNA, 2021
Environmental DNA (eDNA) analysis methods have been developed to detect organism distribution and abundance/biomass in various environments. eDNA degradation is critical for eDNA evaluation.

Proposal for an Electron Antineutrino Disappearance Search Using High-Rate 8Li Production and Decay [PDF]

open access: yes, 2012
This paper introduces a novel, high-intensity source of electron antineutrinos from the production and subsequent decay of 8Li. When paired with an existing ~1 kton scintillator-based detector, this =6.4 MeV source opens a wide range of possible searches

Decay rate of reindeer pellet-groups

open access: yesRangifer, 2008
Counting of animal faecal pellet groups to estimate habitat use and population densities is a well known method in wildlife research. Using pellet-group counts often require knowledge about the decay rate of the faeces.

General decay for a nonlinear pseudo-parabolic equation with viscoelastic term

open access: yesDemonstratio Mathematica, 2022
This work is concerned with a multi-dimensional viscoelastic pseudo-parabolic equation with critical Sobolev exponent. First, with some suitable conditions, we prove that the weak solution exists globally.

Impact of Hall effect on energy decay in magnetohydrodynamic turbulence [PDF]

open access: yes, 2003
We examine numerically the influence of Hall effect corrections to Ohm's law upon the decay of homogeneous compressible magnetohydrodynamic turbulence and conclude that there are no significant differences in global decay rate associated with the Hall ...

On Global Well-Posedness and Temporal Decay for 3D Magnetic Induction Equations with Hall Effect

open access: yesMathematics, 2020
The main purpose of this paper is to study the global existence and uniqueness of solutions for three-dimensional incompressible magnetic induction equations with Hall effect provided that ∥u0∥H32+ε+∥b0∥H2 ...
