Uniform approximation to ¦x¦ by Sinc functions

Journal of Approximation Theory, 1991
AbstractThe best uniform approximation to the function ¦x¦β, β > 0, on [−1, 1] by any of the standard classes of functions of approximation theory has an asymptotic error of at best O(e−c√n), where n is the dimension of the space of approximating functions.

Sinc function representation and three-loop master diagrams [PDF]

Physical Review D, 2001
We test the Sinc function representation, a novel method for numerically evaluating Feynman diagrams, by using it to evaluate the three-loop master diagrams. Analytical results have been obtained for all these diagrams, and we find excellent agreement between our calculations and the exact values. The Sinc function representation converges rapidly, and

GATA4‐Driven Transcription of HtrA1 Promotes Cellular Senescence in Ménière's Disease and Age‐Related Audio‐Vestibular Dysfunction

Advanced Science, EarlyView.
This study identifies the HDAC6/GATA4/HtrA1 axis as a critical driver of cellular senescence in the inner ear. GATA4 nuclear translocation, facilitated by HDAC6 downregulation, transcriptionally activates HtrA1, promoting hair cell senescence, SASP, and audio‐vestibular dysfunction in models of Ménière's disease and age‐related audio‐vestibular ...

Fractional Fokker-Planck Equation

Mathematics, 2017
We shall discuss the numerical solution of the Cauchy problem for the fully fractional Fokker-Planck (fFP) equation in connection with Sinc convolution methods. The numerical approximation is based on Caputo and Riesz-Feller fractional derivatives.

LC3B Mediated SETDB1‐Accounted Alcoholic Steatohepatitis via Lipidation‐Dependent LAP and Lipidation‐Independent Nuclear Stabilization

Advanced Science, EarlyView.
SETDB1 is progressively downregulated in ALD, correlating with disease severity. SETDB1 deficiency impairs LAP by disrupting Rubicon membrane localization, leading to defective lipid droplet clearance. Concurrently, loss of SETDB1 reduces nuclear LC3B, causing R‐loop accumulation and cGAS‐STING‐driven inflammation. Lipidated LC3B mediates LAP‐dependent

Combating VEGFA‐siRNA‐Induced Metabolic Reprogramming via Glucose Utilization Deprivation

Advanced Science, EarlyView.
An ionizable lipid nanoparticle co‐delivers VEGFA siRNA and glucose oxidase to tumors to counteract VEGFA knockdown‐induced, glutamine‐driven metabolic compensation. Enzymatic glucose consumption reverses the adaptive pathways and restores metabolism toward baseline, thereby sensitizing tumors to therapy.

Jordan-Type Inequalities and Stratification

Axioms
In this paper, two double Jordan-type inequalities are introduced that generalize some previously established inequalities. As a result, some new upper and lower bounds and approximations of the sinc function are obtained.

Designing the sinc neural networks to solve the fractional optimal control problem [PDF]

Iranian Journal of Numerical Analysis and Optimization
Sinc numerical methods are essential approaches for solving nonlinear problems. In this work, based on this method, the sinc neural networks (SNNs) are designed and applied to solve the fractional optimal control problem (FOCP) in the sense of the ...

UCHL3 Regulates Subgenomic Flaviviral RNA Condensates to Promote Virus Propagation

Advanced Science, EarlyView.
ABSTRACT Flavivirus subgenomic RNAs (sfRNAs) antagonise antiviral defences, yet how sfRNAs are organized and maintained in cells remains poorly understood. Here we identify ubiquitin C‐terminal hydrolase L3 (UCHL3) as a post‐translational regulator of flavivirus sfRNA stability and function.

Depletion of p75NTR in Schwann Cells Driven by Inflammation Mediates Cutaneous Pain in Psoriasis

Advanced Science, EarlyView.
Psoriasis‐like inflammation induces proliferation and molecular remodeling of cutaneous Schwann cells, marked by reduced p75NTR and increased NGF expression. IL‐17A promotes this process, whereas Schwann cell‐specific p75NTR overexpression alleviates cutaneous pain in vivo.
