A more accurate half-discrete Hardy-Hilbert-type inequality with the logarithmic function

Journal of Inequalities and Applications, 2017
By means of the weight functions, the technique of real analysis and Hermite-Hadamard’s inequality, a more accurate half-discrete Hardy-Hilbert-type inequality related to the kernel of logarithmic function and a best possible constant factor is given ...

A calculation of the Weyl anomaly for 6D conformal higher spins

Journal of High Energy Physics, 2021
In this work we continue the study of the one-loop partition function for higher derivative conformal higher spin (CHS) fields in six dimensions and its holographic counterpart given by massless higher spin Fronsdal fields in seven dimensions.

A Shortcut to (Sun)Flowers: Kernels in Logarithmic Space or Linear Time [PDF]

, 2015
We investigate whether kernelization results can be obtained if we restrict kernelization algorithms to run in logarithmic space. This restriction for kernelization is motivated by the question of what results are attainable for preprocessing via simple and/or local reduction rules.

Flexible Chemiresistive Chitosan‐Glycerol Sensors on Laser‐Induced Graphene Electrodes for Room‐Temperature Ammonia Detection

Advanced Materials Technologies, EarlyView.
Flexible Chitosan‐glycerol sensor integrated with porous laser‐induced graphene (LIG) electrodes enable room‐temperature chemiresistive detection of ammonia (NH3) and proof‐of‐concept detection of fish spoilage. ABSTRACT We report a metal‐free sensor platform combining laser induced graphene (LIG) electrodes with drop‐deposited, glycerol‐plasticized ...

Quadrature error estimates for kernels with logarithmic singularity

Computers & Mathematics with Applications
Boundary integral methods are a powerful tool to solve partial differential equations by reformulating them as integral equations over the boundary of the domain. When dealing with boundary integral methods, and in particular with the numerical integration of layer potentials, it is essential to estimate the magnitude of the error associated with the ...

Enhanced Stability in Zero‐Excess Li‐Metal Batteries via Prelithiated Carbon Nanofiber Interlayers

Advanced Science, EarlyView.
Carbon nanofibers carbonized at 700°C show Li metal deposition predominantly on the side facing the Cu current collector. During delithiation, Li agglomerates remain as inactive lithium on the fiber surface. This behavior can be changed by a modified n‐Buli prelithiation without a washing step, suppressing dead Li formation and therefore enabling ...

Multi-Feature Fusion and Adaptive Kernel Combination for SAR Image Classification

Applied Sciences, 2021
Synthetic aperture radar (SAR) image classification is an important task in remote sensing applications. However, it is challenging due to the speckle embedding in SAR imaging, which significantly degrades the classification performance.

Upper bounds on derivatives of the logarithm of the heat kernel [PDF]

Communications in Analysis and Geometry, 1998
Let \(M\) be a compact, connected Riemannian manifold and denote by \(\Delta\) the Levi-Civita Laplace operator on \(M\). Let \(p_t(x,y)\) be the fundamental solution of the Cauchy initial value problem for the diffusion equation \(u_t=\frac{1}{2}\Delta u\). The main result of this paper asserts that if \(n\) is an arbitrary positive integer then the \(

De Novo Design of Membrane‐Targeting Antimicrobial Peptides Against Gram‐Negative Bacteria Using a Generative Artificial Intelligence Framework

Advanced Science, EarlyView.
Antimicrobial resistance caused by Gram‐negative bacteria remains difficult to overcome due to the protective outer membrane. To address this challenge, a multi‐condition constrained generative AI framework, GenMTAMP is proposed for de novo membrane‐targeting antimicrobial peptide design by integrating physicochemical and spatial structure descriptors.

The central emission vertex of two gravitons

Journal of High Energy Physics
It has recently been shown that there exists an s-channel sequence of classical corrections [1] to the H diagram computed long ago by Amati, Ciafaloni and Veneziano [2].
