A New Single-Stage Three-Phase PFC for Four-Switch Three-Phase Inverter Fed IM Drives

open access: yesAdvances in Electrical and Computer Engineering, 2019
This paper proposes a single-stage three-phase power factor correction (PFC) for four-switch inverter (FSI) fed induction motor (IM) drives. The PFC scheme uses a Cuk converter with only one switch, and consequently, it needs only one control signal ...

Does Institutional Ownership Structure Reduce Greenhouse Gas Emissions? An In‐Depth Study of Corporations Social Responsibility of European‐Listed Firms

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Motivated by the growing attention and concerns surrounding climate change and the potential role of institutional investors' ownership concentration (OC) in reducing corporations' greenhouse gas (GHG) emissions, this article explores the relationship between various forms of institutional ownership and firms' GHG emission intensity. To do so,

Neurobiological correlates of obsessive‐compulsive disorder (OCD): A narrative review

open access: yesIbrain, EarlyView.
Obsessive‐compulsive disorder (OCD) is a common and disabling, as well as underdiagnosed, neuropsychiatric condition characterized by involuntary and unwanted obsessions and/or compulsions often accompanied by states of severe anxiety, distress and shame, as well as other comorbid disorders. Despite the extensive literature available to date, only some

General impedance synthesis using simple switching converters [PDF]

open access: yes, 2006
A general impedance synthesizer using a minimum number of switching converters is studied in this paper. We begin with showing that any impedance can be synthesized by a circuit consisting of only two simple power converters, one storage element (e.g ...

White Matter Dysfunction and Neurotransmitter Basis Underlying the Freezing of Gait in Parkinson's Disease

open access: yesiNew Medicine, EarlyView.
In the freezing of gait in Parkinson's disease, white matter shows decreased local activity but increased functional connectivity. These distinct dysfunctions are uniquely associated with specific neurotransmitter systems (GABA, dopamine, etc.), mapping a new neurochemical basis for this debilitating symptom. ABSTRACT Freezing of gait (FOG) is a severe
