The optical singularities of birefringent dichroic chiral crystals
, 2003 Using a new formalism involving projection from the sphere of directions to the stereographic plane, and associated complex variables, explicit formulae are obtained for the two refractive indices and polarizations in optically anisotropic crystals that ...

Polarization singularities in a stress-engineered optic
Journal of the Optical Society of America A, 2019 We develop a simplified version of a recently presented model to simulate the oblique propagation of polarized light through a thick birefringent element known as a stress-engineered optic (SEO). We use this model to analyze the formation and evolution of three polarization singularities, stars, lemons, and monstars, and experimentally verify the ...

FEBS Open Bio, EarlyView.Evolutionary analysis across 32 placental mammals identified positive selection at residues H148 and W149 in the immune receptor FcγR1. Ancestral reconstruction combined with molecular dynamics simulations reveals how these mutations may influence receptor structure and dynamics, providing insight into the evolution of antibody recognition and immune ...

Exact gravitational plane waves and two-dimensional gravity
Physics Letters B, 2018 We discuss dynamical aspects of gravitational plane waves in Einstein theory with massless scalar fields. The general analytic solution describes colliding gravitational waves with constant polarization, which interact with scalar waves and, for generic ...

Cutaneous Melanoma Drives Metabolic Changes in the Aged Bone Marrow Immune Microenvironment
Aging and Cancer, EarlyView.Melanoma, the deadliest form of skin cancer, increasingly affects older adults. Our study reveals that melanoma induces changes in iron and lipid levels in the bone marrow, impacting immune cell populations and increasing susceptibility to ferroptosis.
