Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background While autoimmune encephalitis (AE) outcomes vary, serostatus‐specific prognostic determinants and institutional clustering effects remain poorly characterized. We aimed to delineate the distinct prognostic architecture of AE, identifying serostatus‐specific risk factors and potential therapeutic windows.

Existence of solutions to n-th order neutral dynamic equations on time scales
Electronic Journal of Differential Equations, 2010 In this article, we study n-th order neutral nonlinear dynamic equation on time scales. We obtain sufficient conditions for the existence of non-oscillatory solutions by using fixed point theory.

On the Convergence of the Approximate Solution to the Optimization Problem for Oscillatory Processes
Қарағанды университетінің хабаршысы. Математика сериясыThis article addresses the non-linear optimization problem of oscillatory processes governed by partial integro-differential equations involving a Fredholm integral operator. A distinctive feature of the problem is that both the objective functional and

Trends in Computational and Applied Mathematics, 2005 In this work the essentially non-oscillatory schemes (ENO) and the weighted essentially non-oscillatory schemes (WENO) are implemented in a cell centered finite volume context on unstructured grids. The 2-D Euler equations will be considered to represent

Linear and weakly nonlinear multi-diffusive convection in a Navier-Stokes-Voigt fluid layer
Arab Journal of Basic and Applied SciencesThe stability of a triply diffusive Voigt fluid layer, where fluid density is influenced by three stratifying agents with different diffusivities (e.g. heat, solute, and another solute like a third agent), has been examined. The linear stability analysis

On periodic solutions in the non-dissipative Lorenz model: the role of the nonlinear feedback loop
Tellus: Series A, Dynamic Meteorology and Oceanography, 2018 In this study, we discuss the role of the linear heating term and nonlinear terms associated with a non-linear feedback loop in the energy cycle of the three-dimensional (X–Y–Z) non-dissipative Lorenz model (3D-NLM), where (X, Y, Z) represent the ...

Continuability and (non-) oscillatory properties of solutions of generalized Liénard equation
Hiroshima Mathematical Journal, 1990 The paper deals with the equation (1) \(x''+f(x)x'+g(x)=0\) where f and g are continuous on R and \(xf(x)>0\), \(xg(x)>0\) for all \(x\neq 0\). There are treated the problems of continuability of the solutions, the properties of (ultimately) positive and negative solutions, the nonexistence of such solutions and consequently there are stated sufficient

Advanced Engineering Materials, EarlyView.This study explores the discrepancies between bulk mechanics and spatial mapping in a tissue‐mimetic hydrogel model. Microplastic particles create localized stiff mechanical microenvironments that are detectable by cellular‐scale nanoindentation but leave bulk properties unchanged as measured by rheology.

A Novel Approach to Estimate the Transition Temperature via Dynamic Nanoindentation
Advanced Engineering Materials, EarlyView.A new dynamic nanoindentation‐based method was developed that uses the stiffness ratio as an indicator of the elastic–plastic deformation contributions at different temperatures. The approach successfully identified transition temperatures in ferritic steel and distinguished them from continuously ductile austenitic steel.
