Dynamic Peak Threshold Estimation Method for Noise Mitigation in Hybrid PLC/VLC Systems

IEEE Access
Most communication systems suffer from signal distortions as a result of noise interference. These distortions have multiple effects on communication channels, including higher bit error rate (BER), reduced signal-to-noise ratio (SNR), and restricted ...

Evaluating Brief Behavioural Activation for depression in adolescents with acquired brain injury using a single‐case experimental design

JCPP Advances, EarlyView.
Abstract Background Adolescents who have had an acquired brain injury (ABI) commonly experience depression. Brief Behavioural Activation (Brief BA) is a successful, values‐based intervention for managing depression in neurotypical adolescents. This study investigated the effectiveness of Brief BA, using a single‐case experimental design, with ...

Reduced occurrence of alpha waves during resting state predicts high attention‐deficit/hyperactivity disorder traits in young adults

JCPP Advances, EarlyView.
Abstract Background Attention‐deficit/hyperactivity disorder (ADHD) is a neurodevelopmental condition with significant cognitive and social impacts. Identifying reliable biomarkers for ADHD is crucial for developing personalised therapies. Electroencephalography (EEG) alpha oscillations (8–12 Hz) have been suggested as a potential biomarker, but ...

Analytical bit error rate performance evaluation of an orthogonal frequency division multiplexing power line communication system impaired by impulsive and Gaussian channel noise

The Journal of Engineering, 2015
An analytical approach is presented to evaluate the bit error rate (BER) performance of a power line (PL) communication system considering the combined influence of impulsive noise and background PL Gaussian noise.

Infant frontal alpha asymmetry predicts social attention and transdiagnostic risk for emotional reactivity

JCPP Advances, EarlyView.
Abstract Background Differences in Frontal Alpha Asymmetry (FAA), derived from the electroencephalogram (EEG), have been associated with approach‐withdrawal behavior, although inconsistently. The current study examined how early patterns of FAA during the first 2 years of life relate to various socioemotional characteristics (at 2 years) and ultimately

Co‐development of a digital animated video on attention deficit hyperactivity disorder with children and parents/carers

JCPP Advances, EarlyView.
Abstract Background When receiving an attention deficit hyperactivity disorder (ADHD) diagnosis, children and families/carers need clear and accurate information about the condition in a suitable format. However, many of the available resources are complex or provide content that is not evidence‐based.

Negative Capability and Entrepreneurial Action

Strategic Change, EarlyView.
ABSTRACT Entrepreneurs operate in environments marked by uncertainty. Existing theories of entrepreneurial action largely emphasize an entrepreneur's ability to make judgments and take decisive action despite ongoing uncertainty—competencies primarily supported by what we term positive capability (PC).

Distribution based definition of impulse noise [PDF]

The Journal of the Acoustical Society of America, 1985
Existing definitions of impulse noise are based on estimates of either the decay of the noise envelope, the repetition rate of the peaks, or a comparison of single peak level to rms level. Because each of these measures fails to fully characterize at least one of the relevant characteristics of an impulse, many exceptions to these classifications can ...

Dynamic Evolution and Transformative Trends in the Consumer Market: A Technology Paradox Perspective

Psychology &Marketing, EarlyView.
ABSTRACT The consumer market is defined by tensions arising from the clash between technological advancement and consumer psychology. Current research lacks a unifying framework to explain these contradictions. Addressing this gap, we introduce a conceptual model based on technology paradox theory, which maps the dynamic process from antecedents ...

Joint channel and impulsive noise estimation method for MIMO-OFDM systems

Tongxin xuebao, 2021
Aiming at the impulsive noise occurring in MIMO-OFDM systems， a joint channel and impulsive noise estimation method based on the multiple measurement vector compressed sensing theory was proposed.The channel impulse response and the impulsive noise were ...
