Particle Creation by a Moving Boundary with Robin Boundary Condition
, 2006 We consider a massless scalar field in 1+1 dimensions satisfying a Robin boundary condition (BC) at a non-relativistic moving boundary. We derive a Bogoliubov transformation between input and output bosonic field operators, which allows us to calculate ...

FEBS Letters, EarlyView.This perspective highlights emerging insights into how the circadian transcription factor CLOCK:BMAL1 regulates chromatin architecture, cooperates with other transcription factors, and coordinates enhancer dynamics. We propose an updated framework for how circadian transcription factors operate within dynamic and multifactorial chromatin landscapes ...

The possible mechanism for a frequency shift by a time-varying of medium features
Journal of Telecommunications and Information Technology, 2000 The optical frequency shift of an electromagnetic wave reflecting from a boundary of a medium is studies for two cases: for temporal variations of medium permittivity, and for a moving plasma boundary. It has been shown that a simultaneous occurrence of

Passive scalars, moving boundaries, and Newton's law of cooling
, 2014 We study the evolution of passive scalars in both rigid and moving slab-like domains, in both horizontally periodic and infinite contexts. The scalar is required to satisfy Robin-type boundary conditions corresponding to Newton's law of cooling, which ...

Drug diffusion from polymeric delivery devices: a problem with two moving boundaries [PDF]
, 2011 An existing model for solvent penetration and drug release from a spherically-shaped polymeric drug delivery device is revisited. The model has two moving boundaries, one that describes the interface between the glassy and rubbery states of polymer, and ...

Disordered but rhythmic—the role of intrinsic protein disorder in eukaryotic circadian timing
FEBS Letters, EarlyView.Unstructured domains known as intrinsically disordered regions (IDRs) are present in nearly every part of the eukaryotic core circadian oscillator. IDRs enable many diverse inter‐ and intramolecular interactions that support clock function. IDR conformations are highly tunable by post‐translational modifications and environmental conditions, which ...

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.

The numerical solution of thawing process in phase change slab using variable space grid technique [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2007 This paper focuses on the numerical analysis of melting process in phase change material which considers the moving boundary as the main parameter. In this study, pure ice slab and saturated porous packed bed are considered as the phase change material ...

Characterization and Equilibrium Study of Drug Release of pH-Responsive Chitosan-graft-Maleic Film
International Journal of Technology, 2022 This paper reports on a pH responsive material and a mathematical model for a drug release study. This material can be applied as a tumor drug carrier, because the tumor tissue has a different pH (5.7–7.8) compared to the ...

Left-Right Entanglement Entropy of Boundary States
, 2014 We study entanglement entropy of boundary states in a free bosonic conformal field theory. A boundary state can be thought of as composed of a particular combination of left and right-moving modes of the two-dimensional conformal field theory.
