Parameter Estimation of LFM Signals Based on FOTD-CFRFT under Impulsive Noise

Fractal and Fractional, 2023
Due to the short duration and high amplitude characteristics of impulsive noise, these parameter estimation methods based on Gaussian assumptions are ineffective in the presence of impulsive noise. To address this issue, a LFM signal parameter estimation

Waiting for a Release: The Expectation in Virtual Gaming Communities

Journal of Consumer Behaviour, EarlyView.
ABSTRACT This study examines how virtual gaming communities influence and maintain player expectations before, during, and after a game's release. A mixed‐methods study was conducted, comprising a netnography followed by an experiment. First, a netnographic study was conducted over 12 months, tracking communities to understand player behavior and ...

Speech Denoising Using Transform Domains in the Presence of Impulsive and Gaussian Noises

IEEE Access, 2017
The speech denoising problem in the presence of mixed impulsive and Gaussian noises is investigated by exploiting transform domains. To that end, the proposed noise suppression scheme is a cascaded form consisting of an impulsive noise suppression module

Executive functions and self‐limited epilepsy with centro‐temporal spikes: A scoping review

Epileptic Disorders, EarlyView.
Abstract Executive functions are a set of high‐level cognitive processes necessary for planning, organization, decision‐making, self‐control, and attention, and are carried out in the anterior frontal lobes. An impairment in executive functioning might present as difficulties in planning and organizing activities, in attention and concentration, in ...

Epilepsy syndromes classification

Epilepsia Open, EarlyView.
Abstract Epilepsy syndromes are distinct electroclinical entities which have been recently defined by the International League Against Epilepsy Nosology and Definitions Task Force. Each syndrome is associated with “a characteristic cluster of clinical and EEG features, often supported by specific etiologic findings”.

Cyclostationarity-based DOA estimation algorithms for coherent signals in impulsive noise environments

EURASIP Journal on Wireless Communications and Networking, 2019
Estimating direction of arrival (DOA) is important in a variety of practical applications. Conventional cyclostationarity-based coherent DOA estimation algorithms are not robust to non-Gaussian α-stable impulsive noise.

Direction of arrival estimation under Class A modelled noise in shallow water using variational Bayesian inference method

IET Radar, Sonar & Navigation, 2022
The shallow water noise shows obvious impulsive property, which greatly degrades the direction of arrival (DOA) performance due to the conventional design concept based on the Gaussian assumption.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

FlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Imperfect Synthetic Controls

Journal of Applied Econometrics, EarlyView.
ABSTRACT The synthetic control method assumes the existence of a perfect synthetic control, which cannot exist if the outcomes are functions of transitory shocks with nonzero asymptotic variance and may not exist even in expectation for the treated unit. This paper first shows the benefits of estimating synthetic controls for all units.
