Memoryless quasi-Newton-type methods via some weak secant relations for large-scale unconstrained optimization

Journal of Inequalities and Applications
This article presents two variants of memoryless quasi-Newton methods with backtracking line search for large-scale unconstrained minimization. These updating methods are derived by means of a least-change updating strategy subjected to some weaker form ...

When Density Matters: Hydraulic and Salinity Evolution in Groundwater‐Fed Pit Lakes in Semiarid and Arid Climates

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.

The Effect of Listening Strategy Intervention on the Development of Young Learners’ L2 Listening Skills

International Journal of Applied Linguistics, EarlyView.
ABSTRACT The impact of strategy intervention on second language (L2) listening development has been explored in various contexts; however, research on both implicit and explicit listening strategy interventions for young learners remains limited.

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.

Comparison of conjunctival pedicle flap to corneal fixation strength achieved by Tisseel® fibrin glue, ethyl cyanoacrylate adhesive, ReSure® hydrogel sealant, and conventional suturing with 8‐0 VICRYL® ophthalmic suture

Veterinary Ophthalmology, Volume 28, Issue 2, Page 253-263, March 2025.
Abstract Objective To determine and compare the fixation strength of conjunctival pedicle flaps to cornea achieved via conventional ophthalmic suture and three different adhesive compounds. Animals Studied Ex vivo porcine globes. Procedures Following a 6 mm wide 500‐micron‐restricted depth lamellar keratectomy, conjunctival pedicle flaps were secured ...

Non-asymptotic study of quasi-Newton methods with application in large-scale machine learning

Quasi-Newton methods are among popular optimization algorithms for solving convex programs since they serve as a middle ground between first-order methods and second-order Newton-type algorithms.
