Class of fully soft-switched power factor correction circuits

, 1995
This paper presents a class of soft-switched power factor correction circuits (PFC) based on the quasi-resonant (QR) principle. All power devices in the PFC converter can be switched at zero-voltage and/or zero current conditions, thus reducing switching

Cognitive reappraisal modulates neural responses to aversive sensory stimulation in autistic youth

Journal of Child Psychology and Psychiatry, EarlyView.
Background Sensory over‐responsivity (SOR) is highly prevalent and impairing in autism spectrum disorder (ASD). SOR has been associated with sensory‐limbic hyperresponsivity and reduced prefrontal top‐down regulation during sensory stimulation. There are few evidence‐based treatments for SOR, but cognitive reappraisal, an emotion regulation strategy ...

Emotional problems and dysregulation in children/youth with ADHD: predictive and moderating effects in a randomized controlled trial of methylphenidate and neurofeedback

Journal of Child Psychology and Psychiatry, EarlyView.
Background Children and adolescents with Attention‐Deficit/Hyperactivity Disorder (ADHD) often show increased emotional dysregulation (ED) and internalizing emotional problems (iEP). However, the predictive and moderating role of these emotional difficulties in the treatment of ADHD—particularly regarding pharmacological (methylphenidate, MPH) and non ...

Power factor correction using boost converter technique: article / Nur Zati Akmar Lukeman [PDF]

, 2013
This paper describes a single phase rectifier with improved power factor by using the boost converter technique. Low power factor is caused by non-linearity of the input current.

Flexible absolute circuit for advanced power factor correction controller

, 2016
© 2016 IEEE. In this paper, a flexible absolute circuit of advanced power factor correction (PFC) control for a bridgeless boost converter is proposed. The proposed circuit are able to eliminate the diode-bridge short-circuit problem if negative sensing ...

Mini social cognition and emotional assessment: Diagnostic performance and neural correlates in behavioural‐variant frontotemporal dementia

Journal of Neuropsychology, EarlyView.
Abstract We aimed at validating the Mini Social Cognition and Emotional Assessment (Mini‐SEA) in a German cohort of mildly impaired behavioural‐variant frontotemporal dementia (bvFTD) patients and healthy controls. The Mini‐SEA comprises the Facial Emotion Recognition Test (FERT) and the Faux Pas Test (FPT) measuring Theory of Mind (ToM) abilities in ...
