On the Abscissa of Convergence of Laplace–Stieltjes Integrals in the Euclidean Real Vector Space ${\mathbb{R}}^p$

Axioms
New estimates for the convergence abscissas of the multiple Laplace–Stieltjes integral are obtained. There is described the relationship between the integrand function, the Lebesgue–Stieltjes measure, and the abscissa of convergence of the multiple ...

Asymptotic Analysis of the Static Bidomain Model for Pulsed Field Cardiac Ablation

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Cardiac arrhythmias are caused by faulty electrical signals in the heart, which lead to chaotic wave propagation and impaired cardiac function. This work focuses on a non‐thermal ablation technique based on electroporation (EP), a promising method for treating arrhythmias, called pulsed field ablation (PFA).

On absolutely convergent Dirichlet series [PDF]

Proceedings of the American Mathematical Society, 1957
satisfying 1 b,j < oo, if and only if f(s) is bounded away from zero in the half-plane o?0. This discovery amounts to a determination of the spectrum of the Banach-algebra element associated with f(s), and it thus makes available for the theory of ordinary Dirichlet series the well-known theorem of Gelfand on analytic functions of Banach-algebra ...

Inner‐Layer Asymptotics in Partially Perforated Domains: Coupling Across Flat and Oscillating Interfaces

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The article examines a boundary‐value problem in a bounded domain Ωε$$ {\Omega}_{\varepsilon } $$ consisting of perforated and imperforate regions, with Neumann conditions prescribed at the boundaries of the perforations. Assuming the porous medium has symmetric, periodic structure with a small period ε$$ \varepsilon $$, we analyze the limit ...

On Recovering Sturm--Liouville-Type Operator with Delay and Jump Conditions [PDF]

Sahand Communications in Mathematical Analysis
In this manuscript, the second order differential operators with constant delay and transmission boundary conditions are studied. The asymptotic forms of the characteristic functions and eigenvalues  of the operators are obtained.

An integrated integral projection model (IPM²) to disentangle size-structured harvest and natural mortality. [PDF]

J Anim Ecol
An IPM2—a combination of an integrated population model and integral projection model—creates a synergistic modelling framework useful for disentangling multiple size‐structured demographic rates and understanding the effectiveness of invasive European green crab removal efforts.

Existence Analysis of a Three‐Species Memristor Drift‐Diffusion System Coupled to Electric Networks

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT The existence of global weak solutions to a partial‐differential‐algebraic system is proved. The system consists of the drift‐diffusion equations for the electron, hole, and oxide vacancy densities in a memristor device, the Poisson equation for the electric potential, and the differential‐algebraic equations for an electric network.

A regional implementation of a mixed finite‐element, semi‐implicit dynamical core

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A regional version of a new dynamical core with an iterated semi‐implicit time discretisation and mixed finite‐element spatial discretisation is described. This involves modifying the mixed‐system and Helmholtz‐preconditioner equations to use lateral boundary condition (LBC) data specified by a driving model.

Coefficient Estimates for Dirichlet Series [PDF]

Transactions of the American Mathematical Society, 1970
Some subsequent papers in much the same vein are due to G. Halasz [3] and to J. M. Anderson and K. G. Binmore [1]. Halasz has obtained estimates for ani 1 an, and Z1 IanI when An + l/Anq> 1 and f satisfies appropriate conditions. The paper of Anderson and Binmore is concerned with the application of coefficient estimates to the study of entire ...

Local labor market frictions and platform‐based entrepreneurship

Strategic Entrepreneurship Journal, EarlyView.
Abstract Research Summary Building on prior research about the heterogeneous impact of labor shocks on individuals' propensity to start businesses, we explore how local labor market frictions affect individuals' selection into platform‐based entrepreneurship.
