Efficient Numerical Quadrature for Highly Oscillatory Integrals with Bessel Function Kernels

Mathematics
In this paper, we investigate efficient numerical methods for highly oscillatory integrals with Bessel function kernels over finite and infinite domains. Initially, we decompose the two types of integrals into the sum of two integrals.

A highly accurate numerical method for solving boundary value problem of generalized Bagley‐Torvik equation

Mathematical Methods in the Applied Sciences, EarlyView.
A highly accurate numerical method is given for the solution of boundary value problem of generalized Bagley‐Torvik (BgT) equation with Caputo derivative of order 0<β<2$$ 0<\beta <2 $$ by using the collocation‐shooting method (C‐SM). The collocation solution is constructed in the space Sm+1(1)$$ {S}_{m+1}^{(1)} $$ as piecewise polynomials of degree at ...

Regional analysis of spatiotemporal trends in Colorado potato beetle abundance

Pest Management Science, EarlyView.
Leveraging a large data set on Colorado potato beetles in Wisconsin, we examine spatial and temporal abundance trends. Spatiotemporal statistical models substantially improve fit and show that climate and management factors are positively associated with abundance levels.

Insights From the Alphasat Aldo Paraboni Experiment at Tito Scalo and Spino d'Adda: Characterizing Scintillation and Rain Attenuation at Ka‐ and Q‐Band Frequencies

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT We present experimental results on the relationship between rain attenuation and simultaneous scintillation during rain events, based on beacon signal measurements at 19.7 (Ka‐band) and 39.4 GHz (Q‐band) from the geosynchronous Alphasat satellite (25° E), received at two Italian ground stations, Spino d'Adda (42.1° slant path) and Tito Scalo ...

Naprężenia, przemieszczenia i temperatura w ograniczonym ośrodku sprężystym przy uwzględnieniu sprzężenia termomechanicznego

Engineering Transactions, 1968
The mass forces are disregarded in the present paper. By applying the method devised by W. Nowacki [1] partial separation of the equations of e equations of thermoelasticity is achieved by generalizing Galerkin's function to the case of thermodynamical ...

Integrating Image Segmentation and Deep Learning to Improve Radio Frequency Propagation Models

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper proposes a multi‐sensor approach to improve radio frequency (RF) propagation models, which play a key role in the rapidly expanding field of connected vehicle technology. Focusing on the 1‐ to 20‐GHz frequency range, which is critical for both satellite‐to‐vehicle and base station‐to‐vehicle communications, our study introduces a ...

On the Modified Bessel Functions of the First Kind - dotepsilon- On Barrelling for a Material in Finite Elasticity

, 1983
A. On the modified Bessel functions of the first kind: We consider the functions v (t) t I (t) / I + 1 (t) where I are the modified Bessel functions of the first kind of order 0. We prove that v is strictly monotone and strictly convex on R+.

Caputo-hybrid fractional approach to estimates of corrected Euler-Maclaurin-type with computational analysis and applications

Journal of Inequalities and Applications
In this manuscript, firstly we introduce a new auxiliary result for the Caputo-Hybrid fractional operator ( P c a p ) $(P_{cap})$ . As a result, we obtain improved hybrid estimates of Euler-Maclaurin-type for both first- and -second-order differentiable ...

3D Nanoprinted Structures Promote Robust Integration of Brain Organoids into Topography‐Guided Neuronal Networks

Small, EarlyView.
Dedicated cultivation platforms facilitate the implementation of brain organoids in guided neuronal networks. Fabrication is enabled by two‐photon polymerization‐based 3D nanoprinting (3DN) and allows for cultivation in standard 12‐well plates. Fine features, namely slopes, funnels, rods, steps, and walls, facilitate and promote organoid positioning ...

Label‐Free YaxAB Nanopore Fingerprinting of Cancer‐Associated Single‐Residue Bcl‐xL Variants

Small Methods, EarlyView.
A YaxAB nanopore workflow enables label‐free single‐molecule fingerprinting of Bcl‐xL variants. Combined normalized current blockade and noise features generated reproducible current fingerprints for wild‐type Bcl‐xL and the cancer‐associated N136K and R165W variants across independent pores, with WT and N136K remaining distinct despite a mass ...
