A novel hybrid numerical method for delay differential equations with delay-dependent nonlocal condition

Arab Journal of Basic and Applied Sciences
This paper develops a novel hybrid numerical method for the [Formula: see text]-uniform approximation of singularly perturbed second-order delay differential equations subject to delay-dependent nonlocal boundary condition.

Deconvolution of the density of states of tip and sample through constant-current tunneling spectroscopy

Beilstein Journal of Nanotechnology, 2011
We introduce a scheme to obtain the deconvolved density of states (DOS) of the tip and sample, from scanning tunneling spectra determined in the constant-current mode (z–V spectroscopy).

Nonlinear progressive internal gravity wave on fluid of trapezoidal bottom

, 1997
In the present paper we discuss a theoretical model for the interfacial profiles of progressive nonlinear waves which result from introducing a trapezoidal obstacle, of finite height, attached to the bottom below the flow of a stratified, ideal, two ...

Pharmacokinetics, safety, tolerability and fluorescence imaging of nizaracianine triflutate administered in three divided doses to healthy volunteers

British Journal of Clinical Pharmacology, EarlyView.
Aim Fluorescence‐guided surgery enhances intraoperative visualization of anatomical structures. Nizaracianine is a near‐infrared fluorescent agent that is exclusively renally cleared in animal models. It enables real‐time ureteral imaging and identification, potentially reduces risk of injury and facilitates assessment before surgical closure.

Pharmacokinetic profiling of imatinib in relation to CYP3A4 activity in leukaemia patients

British Journal of Clinical Pharmacology, EarlyView.
Aim Imatinib pharmacokinetics exhibit large interindividual variability because of differences in CYP3A4 activity—the main imatinib‐metabolizing enzyme. While therapeutic drug monitoring is effective, it requires steady‐state conditions and frequent sampling.

High-order corrected trapezoidal quadrature rules for functions with a logarithmic singularity in 2-D

, 2002
In this report, we construct correction coefficients to obtain high-order trapezoidal quadrature rules to evaluate two-dimensional integrals with a logarithmic singularity of the form where the domain D is a square containing the point of singularity (0,

A Universal and Actionable Measure of Corporate Sustainability for Strategic Decision Making

Business Strategy and the Environment, EarlyView.
ABSTRACT Managers require a universal, comparable, and decision‐useful measure of corporate sustainability that can reliably inform business strategy, yet such a tool remains absent in the literature and current practice. This paper introduces a comprehensive and operational metric—grounded in Goertz's Basic Framework for developing social science ...

Numerical Study of Fourth-Order Volterra Partial Integrodifferential Equation With Weakly Singular Kernel via Subdivision Collocation Approach

Journal of Function Spaces
In the present article, an emerging subdivision-based technique is developed for the numerical solution of linear Volterra partial integrodifferential equations (LVPIDEs) of order four with a weakly singular kernel. To approximate the spatial derivatives,

Analysis and Approximate Replacement of Tool for Trapezoid Spline Shaft

Jixie chuandong, 2022
The trapezoid spline has the characteristics of good guidance and self-centering， and its application range has been extended to the field of low-speed and high-torque transmission. Based on the tooth profile normal line method， the formula of the hob tooth profile of the trapezoid spline shaft is analyzed.
