An asymptotic behavior of the dilatation for a family of pseudo-Anosov braids [PDF]
arXiv, 2007 The dilatation of a pseudo-Anosov braid is a conjugacy invariant. In this paper, we study the dilatation of a special family of pseudo-Anosov braids. We prove an inductive formula to compute their dilatation, a monotonicity and an asymptotic behavior of the dilatation for this family of braids.

Stimulated Raman Scattering with Optical Vortex Beams
Advanced Photonics Research, EarlyView.This study presents exact analytical expressions for stimulated Raman scattering with Laguerre‐Gaussian beams, revealing signal dependence on topological and hyperbolic momentum. The results provide a theoretical foundation for coherent Raman imaging and detecting orbital angular momentum of light via structured light in nonlinear optics.

Decoupling of kinematical time dilation and gravitational time dilation in particular geometries [PDF]
ActaPhys.Polon.B39:1357-1362,2008, 2007 Two different forms of time dilation, namely, the kinematical time dilation of special relativity and gravitational red shift are coupled during observations of systems moving through a gravitational field. In the particular situation of free fall in a Schwarzschild geometry these two effects are decoupled and in consequence the time dilation, as ...

Advanced Science, EarlyView.PD‐L1 limits neuroinflammation in neovascular AMD by modulating microglial activation. Its deficiency exacerbates vascular leakage and choroidal neovascularization (CNV) via ERK signaling, while enhancing PD‐L1 reduces inflammation and neovascularization. Targeting PD‐L1 may offer a novel immunomodulatory strategy for NVAMD.

Filomat, 2022 We solve the And? dilation problem for linear maps on a vector space asked by Krishna and Johnson in [Oper. Matrices, 2022]. More precisely, we show that any commuting linear maps on vector spaces can be dilated to commuting injective linear maps.
