Evaluating the Role of Corticosteroid Pulse Therapy in Patients With Secondary Progressive Multiple Sclerosis Receiving Mitoxantrone: A Double Blind Randomized Controlled Clinical Trial
Methylprednisolone Mitoxantrone Secondary Progressive Multiple Sclerosis MS therapy
2015/11/9
Background: Multiple sclerosis (MS) is a central nervous system disorder with periods of recurrence and recovery. Mitoxantrone has been approved for secondary progressive MS (SPMS) treatment but data ...
Analog neuron circuits based on both frequency modulation and pulse modulation are investigated. The circuits are compared in terms of size, power, performance, and reliability; frequency modulation s...

Thermal mass flow sensor calorimetric sensor heat pulse bidirectional
2015/1/20
In this work we have designed and simulated a thermal bi-directional integrated circuit mass flow sensor. The approach used here was an extension to the gas flow model given by Mayer and Lechner. The ...
Scattering of a Solitary Pulse on a Local Defect or Breather
Model of nonlinear impulsive nonlinear defect optical pulse long fiber nonlinear optical fiber
2014/12/29
A model is introduced to describe guided propagation of a linear or nonlinear pulse which encounters a localized nonlinear defect, that may be either static or breather-like one. The model with the st...
Short pulse equations and localized structures in frequency band gaps of nonlinear metamaterials
Short pulse propagation nonlinear metamaterials nonlinear dielectric short pulse linear electromagnetic waves magnetic permeability
2014/12/24
We consider short pulse propagation in nonlinear metamaterials characterized by a weak Kerr-type nonlinearity in their dielectric response. Two short-pulse equations (SPEs) are derived for the high- a...
