Frequency-Selective PAPR Reduction for OFDM [PDF]

, 2019
We study the peak-to-average power ratio (PAPR) problem in orthogonal frequency-division multiplexing (OFDM) systems. In conventional clipping and filtering based PAPR reduction techniques, clipping noise is allowed to spread over the whole active ...

Neurodevelopmental burden in young adults undergoing opioid substitution therapy: The role of inattentive and hyperactive/impulsive symptoms

The American Journal on Addictions, EarlyView.
Abstract Background and Objectives Attention‐deficit/hyperactivity disorder (ADHD) is recognized as a condition that can persist into adulthood, often with psychiatric comorbidities that worsen the overall prognosis. ADHD has been associated with substance use disorders (SUDs), especially through symptoms like hyperactivity and impulsivity, while the ...

Caregivers' perspectives of support needs for adolescents with fetal alcohol spectrum disorder

Children &Society, EarlyView.
Abstract Research focused on fetal alcohol spectrum disorder (FASD) is often deficit‐focused, limiting a holistic understanding of individuals' support needs. Families of adolescents with FASD also struggle to access appropriate services. Using semi‐structured interviews, the current study explored the perspectives of seven caregivers of adolescents ...

Species separation and modification of neutron diagnostics in inertial-confinement fusion

, 2014
The different behaviours of deuterium (D) and tritium (T) in the hot spot of marginally-igniting cryogenic DT inertial-confinement fusion (ICF) targets are investigated with an ion Fokker-Planck model.

LCN2‐ACOD1 Signalling Affects the Post‐Injury Regeneration of Skeletal Muscle Through Mediating Ferroptosis

Cell Proliferation, EarlyView.
LCN2 mediates the suppression of C2C12 myoblast proliferation and myotube formation via erastin‐induced ferroptosis. Mechanistically, the LCN2‐ACOD1 axis regulates skeletal muscle growth via mitochondria‐associated ferroptosis, providing a theoretical basis for the prevention and therapy of muscle‐related diseases.
