The m-weak core inverse relative to a Hermitian weight

Demonstratio Mathematica
In this paper, we introduce the concept of E-relative m-weak core inverse of a square matrix as a common extension of the E-weighted core-EP inverse and the m-weak core inverse.

Stability of Viscous Three‐Dimensional Stratified Couette Flow via Dispersion and Mixing

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT This article explores the stability of stratified Couette flow in the viscous 3d$3d$ Boussinesq equations. In this system, mixing effects arise from the shearing background, and gravity acts as a restoring force leading to dispersive internal gravity waves.

Association between patient safety culture, adverse events, and essential practices during childbirth in six Brazilian maternity hospitals

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective This study examines whether hospitals with stronger patient safety culture more consistently follow essential birth practices and have fewer adverse outcomes for mothers and newborns and whether this evidence can guide maternity care priorities in patient safety policy.

Staged Bilateral Magnetic Resonance‐Guided Focused Ultrasound for Treating Essential Tremor: Systematic Review and Meta‐Analysis

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Unilateral magnetic resonance guided focused ultrasound (MRgFUS) thalamotomy reduces tremor in essential tremor, yet disability often persists on the untreated side. The added benefit and safety of a staged contralateral lesion remain uncertain.

Designing γ‐TiAl Alloys With Refined Twin‐Lamellar Microstructures via Machine Learning‐Driven Phase‐Field Methods

Materials Genome Engineering Advances, EarlyView.
Dual‐phase γ‐TiAl alloys with refined twin‐lamellar (RTL) structures exhibit optimal strength‐ductility synergy. Here, phase‐field simulations reveal composition‐stress‐dependent refined twin‐lamellar (RTL) microstructure evolution. Machine learning (CatBoost + NSGA‐III) trained on phase‐field images predicts optimal RTL‐stress‐composition design space.

Real‐Time Fractional Control of an Electrohydraulic System Using Low‐Cost Technology

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Advances in control methods for electrohydraulic systems (EHS) improve performance by addressing nonlinearities and unknown parameters, although most studies are limited to numerical simulations. Furthermore, research with experimental validation often relies on high‐performance computing equipment, specialized data acquisition cards, and ...

Minimal rank weighted weak Drazin inverses

The Electronic Journal of Linear Algebra
The concept of a minimal rank weak Drazin inverse for square matrices is extended to rectangular matrices. Precisely, a minimal rank weighted weak Drazin inverse is introduced and its properties are investigated.

New properties of weighted generalized core-EP inverse in Banach algebras

We characterize the generalized weighted core-EP inverse via the canonical decomposition, utilizing a weighted core-EP invertible element and a quasinilpotent. We then offer a polar-like characterization for the generalized weighted core-EP invertible element.

Distinct Symptom Occurrence Subgroups Among Patients With Colorectal Cancer: Differences in Social Determinants of Health and Diet Quality

Research in Nursing &Health, EarlyView.
ABSTRACT Colorectal cancer (CRC) is a leading cause of cancer mortality in the United States. Many patients with CRC experience physical and psychological symptoms that diminish quality of life and are shaped by social determinants of health (SDOH) and diet quality.
