Design and analysis of power convertors for electric vehicle applications

IOP Conference Series: Earth and Environmental Science, 2019
AbstractThe surge in the cost of fuels can be accounted as a major trigger which leads to the advent of hybrid vehicles. The hybrid electric vehicles are in the reckoning to address the dangers of the exponential increase in contamination of air and global warming associated with greenhouse gases.

Dementia Incidence in Individuals With Parkinson's Disease in the Framingham Heart Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Limited information exists on incident dementia in individuals with Parkinson's disease (PD) in US community‐based samples. We examined cognitive statuses and PD diagnoses of 183 individuals in the Framingham Heart Study (FHS) to establish incident dementia, mortality rates, associations with sex, age at PD onset, and education level.

Peripheral Neutrophil Activation and Extracellular Trap Formation in Amyotrophic Lateral Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
Markers of neutrophil activation are increased in plasma during ALS, and markers of NET formation associate with ALS survival. ABSTRACT Objectives Peripheral neutrophil levels in amyotrophic lateral sclerosis (ALS) inversely correlate with survival, suggesting a role for neutrophils in disease progression.
