A Ground Motion Prediction Model for Average Spectral Acceleration

open access: yesJournal of Earthquake Engineering, 2018
This study presents a ground motion prediction model that directly estimates the median and dispersion of Saavg, defined as the geometric mean of 5%-damped pseudo-acceleration ordinates of oscillators with periods between one fifth and three times the structure’s period of vibration.

Paroxysmal Dyskinesias Secondary to HHV‐6A Encephalitis: The First Case Report and Literature Review

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Paroxysmal dyskinesias encompasses a spectrum of conditions marked by intermittent involuntary movements, with paroxysmal kinesigenic dyskinesias being the most common phenotype. Central nervous system infection is a rare cause of paroxysmal dyskinesias.

Performance of Composite Endpoints Defining Progression Independent of Relapse Activity in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective The characteristics and utility of composite progression independent of relapse activity (cPIRA; worsening on the Expanded Disability Status Scale [EDSS], or 9‐Hole Peg Test, or Timed 25‐Foot Walk Test) were evaluated as an endpoint in relapsing multiple sclerosis (RMS) trials using the ENSEMBLE (NCT03085810) and pooled OPERA I/II ...

Development of Ternary Magnesium Alloys for Laser Powder Bed Fusion: Optimizing Oxide Layer Thickness

open access: yesAdvanced Engineering Materials, EarlyView.
Additive manufacturing of magnesium alloys by laser is difficult because the melting point of the oxide layer is much higher than the evaporation temperature of the metal underneath. Making the oxide layer thinner can solve this problem. Alloying magnesium with strontium makes the oxide layer thinner, especially at 0.5 wt%.
