Generation of vector beams with liquid crystal disclination lines
, 2014 We report that guiding light beams, ranging from continuous beams to femtosecond pulses, along liquid crystal defect lines can transform them into vector beams with various polarization profiles.

Chirality-biased protein expression profile during early stages of bone regeneration
Frontiers in Bioengineering and Biotechnology, 2023 Introduction: Chirality is a crucial mechanical cue within the extracellular matrix during tissue repair and regeneration. Despite its key roles in cell behavior and regeneration efficacy, our understanding of chirality-biased protein profile in vivo ...

Two-dimensional optical ring resonators based on radial Bragg resonance [PDF]
, 2003 A Bragg-reflection-based ring resonator is proposed and analyzed. Closed-form expressions for the field and dispersion curves for radial Bragg gratings and photonic bandgap crystals are derived.

Localized ultraviolet laser microbeam irradiation of early Drosophila embryos: Fate maps based on location and frequency of adult defects [PDF]
, 1979 Drosophila embryos were locally irradiated with a 257-nm laser microbeam during blastoderm and germ band stages. Depending on stage and beam diameter (10–30 μm), from 0 to 45 nuclei were exposed to the uv radiation.

Graphene Photodetector Integrated on a Photonic Crystal Defect Waveguide [PDF]
ACS Photonics, 2018 We present a graphene photodetector for telecom applications based on a silicon photonic crystal defect waveguide. The photonic structure is used to confine the propagating light in a narrow region in the graphene layer to enhance light-matter ...

Dirac Fermions and Domain Wall Defects in 2+1 Dimensions [PDF]
, 1998 We investigate some properties of a system of Dirac fermions in 2+1 dimensions, with a space dependent mass having domain wall like defects.These defects are defined by the loci of the points where the mass changes sign.
