Variance-Guided Regression for Heteroscedastic Data With a Grouping-Based Extension for Nonlinear Prediction. [PDF]
Stat MedABSTRACT Although homoscedasticity is often assumed in linear regression, real data may show variance patterns or residual structures that violate this assumption. We propose VarGuid, a variance‐guided framework for two related settings: Covariate‐dependent conditional variance under a global linear mean model, and residual nonlinear mean structure ...

Fast Nodal Hessian Computation for Peridynamic Fracture Simulation
Computer Graphics Forum, EarlyView.A fast, exact nodal Hessian computation for Non‐Ordinary State‐Based Peridynamics is introduced through analytical simplification and a warp‐centric GPU strategy. The method accelerates preconditioned solvers and Vertex Block Descent, enabling interactive fracture simulation with physical accuracy.

European Journal of Oral Sciences, EarlyView.Abstract This study evaluated (1) the load‐bearing capacity of molars restored with direct occlusal veneers fabricated either from short‐fiber‐reinforced composite (SFRC) or particulate‐filled composite (PFC) and the presence of internal voids within the materials, and (2) effect of water storage on the fracture load and correlation between internal ...

Black Fugitivity in the Sporting Workplace: The Story of Eniola Aluko
Gender, Work &Organization, EarlyView.ABSTRACT Being a Black fugitive involves constant movement: to find and cultivate spaces of safety and hope. In this paper, I curate a sporting archive about the UK Black women's elite football player Eniola Aluko to read her as a Black fugitive. I demonstrate how she traversed a racist and anti‐Black sporting workplace—where she was unfairly demonized

Groundwater, EarlyView.Pit lakes in semiarid and arid regions are often assumed to be terminal sinks for groundwater following mine closure. Using synthetic numerical modeling, we demonstrate that evaporation‐driven density gradients can reverse this behavior, transforming pit lakes into throughflow systems and potentially increasing salinity in adjacent aquifers.

Discharge‐Targeted Hydraulic Tomography to Quantify and Locate Aquifer Discharge
Groundwater, EarlyView.Abstract Quantifying and localizing groundwater discharge is inherently difficult. It requires knowledge about hydraulic conductivity and the hydraulic gradient on the scale of interest. Conventional hydraulic testing, such as pumping tests, may fail in the presence of heterogeneity and complex structural boundaries.

Quasi-Newton's method with correction
Novi Sad Journal of Mathematics - NSJOM, 1996 The problem of solving a system of nonlinear equations \(F(x) = 0\), where \(F:\mathbb{R}^n \rightarrow \mathbb{R}^n\) is a nonlinear mapping of a special form \(F(x) = Ax + G(x)\) with linear part \(A \in \mathbb{R}^{n,n}\) and nonlinear part \(G:\mathbb{R}^n \rightarrow \mathbb{R}^n\), is considered.

Heterogeneity in Manufacturing Growth Risk
Journal of Money, Credit and Banking, EarlyView.Abstract We analyze differences in output growth risk with respect to financial conditions across U.S. manufacturing industries. Using a multilevel quantile regression approach, we find that industries exhibit heterogeneous increases of downside risk in times of tight financial conditions, while upside potential remains stable.
