Edge‐Based Discretizations on Triangulations in Any Dimension, With Special Attention to Four‐Dimensional Space

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 98, Issue 10, Page 1143-1164, October 2026.
This article provides important geometric formulas for node‐centered, edge‐based schemes in any number of dimensions. These formulas are noteworthy, as they do not require the explicit formation of dual regions. We prove several key geometric results, with a particular focus on the four‐dimensional case, due to potential space‐time applications ...

Navigating Supply Shocks: Sector Resilience and Production Prices Through Stochastic Input–Output Modeling

open access: yesMathematical Finance, Volume 36, Issue 4, Page 826-845, October 2026.
ABSTRACT This study develops a novel multivariate stochastic framework for assessing systemic risks, such as climate and nature‐related shocks, within production or financial networks. By embedding a linear stochastic fluid network, interpretable as a generalized vector Ornstein–Uhlenbeck process, into the production network of interdependent ...

Mathematical Modeling of Pulse‐Seeded Metapopulation Dynamics for Andes Hantavirus Border Dispersal

open access: yesEngineering Reports, Volume 8, Issue 9, September 2026.
A pulse‐seeded metapopulation SEIR model for Andes hantavirus maritime dispersal shows that heterogeneous quarantine compliance determines secondary outbreak risk. The weakest‐compliance country governs global containment, while uniform compliance above ∼65%$$ \sim 65\% $$ reduces the global reproduction number below unity.

Improved Optimal Bounds Using the Watson Theorem

open access: yesPhysical Review D, 1973
A method is presented to find an optimal lower bound on the quadratic functional integrals which appear in the derivation of bounds on the hadronic contribution to the muon magnetic moment, or on the Kl3 form factors, when one knows that the function and its derivative take some definite values at the origin and that its phase is given on a part of the

Urban vs. Rural Lifestyles in terms of Theories of Cultural Globalization

open access: yesجامعه شناسی کاربردی, 2013
Introduction   Globalization has indubitably caused local, national, and international sections to meet and intertwine in ways that have historically been unimaginable.

Evaluating the Timing of Sitz Baths After Laser Hemorrhoidoplasty: An Exploratory Study

open access: yesHealth Science Reports, Volume 9, Issue 9, September 2026.
ABSTRACT Background Laser hemorrhoidoplasty (LHP) is a minimally invasive procedure for the treatment of hemorrhoids. Early sitz baths are recommended after conventional hemorrhoidectomy; however, their effectiveness following LHP has not been evaluated.

A novel dual‐decomposition method for non‐convex two‐stage stochastic mixed‐integer quadratically constrained quadratic problems

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 5, Page 3128-3157, September 2026.
Abstract We propose the novel p‐branch‐and‐bound method for solving two‐stage stochastic programming problems whose deterministic equivalents are represented by non‐convex mixed‐integer quadratically constrained quadratic programming (MIQCQP) models. The precision of the solution generated by the p‐branch‐and‐bound method can be arbitrarily adjusted by

On a Watson-like Uniqueness Theorem and Gevrey Expansions

open access: yes, 2005
We present a maximal class of analytic functions, elements of which are in one-to-one correspondence with their asymptotic expansions. In recent decades it has been realized (B. Malgrange, J. Ecalle, J.-P. Ramis, Y. Sibuya et al.), that the formal power series solutions of a wide range of systems of ordinary (even non-linear) analytic differential ...

Adverse Moral Selection: Moral Injury and the Moral Composition of the Clinical Workforce

open access: yesJournal of Evaluation in Clinical Practice, Volume 32, Issue 6, September 2026.
ABSTRACT Rationale Clinician distress has been progressively reframed over the past decade: from burnout, construed as an individual failure of resilience, to moral injury, construed as a systemic failure that betrays the practitioner's commitment to the patient.

Adaptive Estimation for Weakly Dependent Functional Times Series

open access: yesJournal of Time Series Analysis, Volume 47, Issue 5, Page 1013-1027, September 2026.
ABSTRACT We propose adaptive mean and autocovariance function estimators for stationary functional time series under 𝕃p−m‐approximability assumptions. These estimators are designed to adapt to the regularity of the curves and to accommodate both sparse and dense data designs.
