Homophily‐adjusted social influence estimation

Canadian Journal of Statistics, EarlyView.
Abstract Homophily and social influence are two key concepts of social network analysis. Distinguishing between these phenomena is difficult, and approaches to disambiguate the two have been primarily limited to longitudinal data analyses. In this study, we provide sufficient conditions for valid estimation of social influence through cross‐sectional ...

Optimising hypoxia PET imaging and its applications in guiding targeted radiation therapy for non‐small cell lung cancer: a scoping review

Journal of Medical Radiation Sciences, Volume 72, Issue 1, Page 106-118, March 2025.
This review article reports that quantification of hypoxic volumes using PET in the pre‐radiation therapy setting is of prognostic value and indicative of treatment response in non‐small cell lung cancer. Abstract Introduction Non‐small cell lung cancer (NSCLC) is the leading cause of cancer‐related death. Definitive treatment includes chemotherapy and

An inverse nodal problem of a conformable Sturm-Liouville problem with restrained constant delay

Boundary Value Problems
This paper presents a new technique: a conformable derivative for the inverse problem of a Sturm-Liouville problem with restrained constant delay. Solutions to the Sturm-Liouville problem often involve eigenfunctions and eigenvalues, which have important

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Solving inverse nodal problem with frozen argument by using second Chebyshev wavelet method

summary:We consider the inverse nodal problem for Sturm-Liouville (S-L) equation with frozen argument. Asymptotic behaviours of eigenfunctions, nodal parameters are represented in two cases and numerical algorithms are produced to solve the given ...

Recovery from electrode position uncertainties in geophysical electrical resistance tomography – Application to moisture transport imaging

Near Surface Geophysics, EarlyView.
Abstract In studies of subsurface hydrology, monitoring and imaging techniques are used to estimate the moisture content, or to track moisture or injected tracer movement. One applied imaging technique is electrical resistance tomography (ERT), in which measurements collected using electrodes placed on the ground surface or in boreholes are used to ...

Oscillation estimates of eigenfunctions via the combinatorics of noncrossing partitions

Discrete Analysis, 2017
Oscillation estimates of eigenfunctions via the combinatorics of noncrossing partitions, Discrete Analysis 2017:13, 20 pp. An important phenomenon that often occurs with linear operators is that the complexity of their eigenfunctions is closely related ...
