Calculation of the line shapes of electronic transitions at defects using the frozen Gaussian technique [PDF]
, 1999 Calculations of the optical properties of defects in semiconductors or multiphonon transition rates presently make far more severe approximations than standard electronic structure calculations. One major challenge is how one can handle realistically the

Pseudospin-Polarized Topological Line Defects in Dielectric Photonic Crystals [PDF]
IEEE Transactions on Antennas and Propagation, 2019 Electromagnetic (EM) topological insulators have been extensively explored due to the robust edge states they support. In this work, we propose a topological EM system based on a line defect in topologically nontrivial photonic crystals (PCs).

Attractor flows from defect lines [PDF]
Journal of Physics A: Mathematical and Theoretical, 2011 Deforming a two dimensional conformal field theory on one side of a trivial defect line gives rise to a defect separating the original theory from its deformation. The Casimir force between these defects and other defect lines or boundaries is used to construct flows on bulk moduli spaces of CFTs.

Defect Line Coarsening and Refinement in Active Nematics
Physical Review Letters, 2023 Active matter is naturally out of equilibrium which results in the emergence of diverse dynamic steady states, including the omnipresent chaotic state known as the active turbulence. However, much less is known how active systems dynamically depart out of these configurations, such as get excited or damped to a different dynamic steady state.

FEBS Letters, EarlyView.Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Line-defect calibration for line-scanning projection display
Optics Express, 2009 A method of line-defect calibration for line-scanning projection display is developed to accomplish acceptable display uniformity. The line scanning display uses a line modulating imaging and scanning device to construct a two-dimensional image. The inherent line-defects in an imaging device and optical lenses are the most fatal performance-degrading ...

Bootstrapping line defects in $$ \mathcal{N} $$ = 2 theories [PDF]
Journal of High Energy Physics, 2019 We study half-BPS line defects in $$ \mathcal{N} $$ N = 2 superconformal theories using the bootstrap approach. We concentrate on local excitations constrained to the defect, which means the system is a 1d defect CFT with osp(4∗|2) symmetry.

Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions
FEBS Letters, EarlyView.The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

2D ISING MODEL WITH A DEFECT LINE
Modern Physics Letters A, 1994 We study the two-dimensional Ising model with a defect line and evaluate multipoint energy correlation functions using nonperturbative field-theoretical methods. We also discuss the evaluation of the two-spin correlator on the defect line.

FEBS Letters, EarlyView.This review focuses on the role of autophagy and mitophagy in maintaining pancreatic β‐cell function and homeostasis. We discuss how genetic defects affecting these pathways contribute to the development of type 1, type 2, monogenic, and gestational diabetes. We further explore their potential as therapeutic targets. Created in BioRender.
