On the Fourth Power Mean of a Sum Analogues to Character Sums Over Short Intervals

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2011
The paper under review deals with the sum \(\sum_{1\leq n\leq N}(-1)^n\chi(n)\), where \(\chi\) denotes a Dirichlet character modulo \(q\geq 2\). The first theorem gives the following asymptotic formula \[ \sum_{\chi\bmod q}\Bigl|\sum_{n\leq N}(-1)^nn^k\chi(n)\Bigr|^4=\frac{80\ln N-50\ln 2}{(2k+1)^3n^2}\frac{\varphi^4(q)}{q^3}N^{4k+2}\prod_{p|q}\frac{p}

Sex‐Stratified Association of Regional Dopamine Transporter Binding With Disease Progression in Amyotrophic Lateral Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To clarify the clinical relevance of dopamine transporter single‐photon emission computed tomography (DAT‐SPECT) abnormalities in amyotrophic lateral sclerosis (ALS), with a prespecified focus on sex‐stratified associations with disease progression and short‐term prognosis.

Adaptive fuzzy integrated LMS based control strategy for voltage power quality enhancement

open access: yese-Prime: Advances in Electrical Engineering, Electronics and Energy
In this paper, an adaptive Takagi Sugeno (TS) Fuzzy integrated Mixed Order Normalized Least Mean Square/Fourth Algorithm (MONLMS/F) is proposed for the unresolved voltage power quality issues in distribution system. The proposed control utilizes the cost

Electroencephalographic Normalization as a Biomarker of Clinical Recovery in Down Syndrome Regression Disorder

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Down syndrome regression disorder is a syndrome characterized by subacute loss of cognitive, behavioral, and functional abilities in individuals with Down syndrome. Electroencephalography abnormalities are frequently observed during evaluation, but it remains unclear whether these findings represent a dynamic marker of disease ...

Thalamo‐Lesional Connectivity Signatures of Bilateral Tonic–Clonic Seizures in Focal Cortical Dysplasia‐Related Epilepsy

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Focal cortical dysplasia (FCD) is the most common etiology of drug‐resistant epilepsy in children. Focal to bilateral tonic–clonic seizures (FBTCS) mark a high risk of drug‐resistant epilepsy and involve thalamocortical circuitry in their generation and propagation.

The impact of a random metric upon a diffusing particle

open access: yesScientific Reports
We show that if the singularity of the covariance of the random metric is $$\vert \textbf{x}\vert ^{-2\gamma }$$ | x | - 2 γ then the mean value of the fourth power of the distance achieved in time t by a diffusing particle behaves as $$t^{2(1-\gamma )}$$

Clutter attenuation‐stable normalised least‐mean fourth for PBR

open access: yesElectronics Letters, 2016
The stable normalised least‐mean fourth (SNLMF) algorithm is developed in the passive bistatic radar (PBR) system to realise the interference cancellation. The larger power of the reference signal may lead to the poor convergence rate.
