Energy distribution of charged dilaton black holes
, 1998 Chamorro and Virbhadra studied, using the energy-momentum complex of Einstein, the energy distribution associated with static spherically symmetric charged dilaton black holes for an arbitrary value of the coupling parameter $\gamma$ which controls the ...

Helmholtz solitons in optical materials with a dual power-law refractive index [PDF]
, 2010 A nonlinear Helmholtz equation is proposed for modelling scalar optical beams in uniform planar waveguides whose refractive index exhibits a purely-focusing dual powerlaw dependence on the electric field amplitude.

Spatiotemporal dispersion and wave envelopes with relativistic and pseudorelativistic characteristics [PDF]
, 2012 A generic nonparaxial model for pulse envelopes is presented. Classic Schro¨dinger-type descriptions of wave propagation have their origins in slowly-varying envelopes combined with a Galilean boost to the local time frame.

Helmholtz-Manakov solitons [PDF]
, 2005 A novel spatial soliton-bearing wave equation is introduced, the Helmholtz-Manakov (H-M) equation, for describing the evolution of broad multi-component self-trapped beams in Kerr-type media. By omitting the slowly-varying envelope approximation, the H-M

Freedon study: Real‐life outcomes of cenobamate in different lines of treatment
Epilepsia, EarlyView.Abstract Objectives Cenobamate is an antiseizure medication (ASM) with proven effectiveness in individuals with highly refractory epilepsy. This study investigated the effectiveness and tolerability of cenobamate in different treatment lines and a less refractory setting. Methods This was a multicenter, retrospective, observational study.
