An Extended Formulation With Valid Inequalities for the Capacitated Steiner Arborescence Problem
Networks, Volume 88, Issue 2, Page 250-274, September 2026.ABSTRACT Given a directed graph, the Capacitated Steiner Arborescence Problem (CSAP) aims to determine the least‐cost connection from the root node to terminal nodes requiring a demand through Steiner nodes coming with a capacity, such that there is a unique path from the root to each terminal. This paper presents a new extended formulation of the CSAP,

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.ABSTRACT In this work, we present an extension of the semi‐discrete Lagrangian‐Eulerian numerical scheme for diffusive‐dispersive conservation law problems, including a jump discontinuous flux function. As in the one‐dimensional scalar hyperbolic case, the no‐flow curves also organize the geometry of the method.

Financial Climate‐Risk Measurement, Impact Funds, and Green Transitions
Journal of Accounting Research, Volume 64, Issue 4, Page 1867-1903, September 2026.ABSTRACT Regulators are contemplating or mandating precise measurement of financial climate‐risk exposure to promote sustainable investments. We show that such mandates can be counterproductive in the presence of social funds that catalyze change by subsidizing the adoption of cleaner production technologies.

International 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

A Microphysical Model for Predicting Magma Fragmentation
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Explosive volcanic eruptions occur when coherent bubbly magma breaks apart in a process called “fragmentation.” Accurate conceptual and numerical models of fragmentation are a pre‐requisite for prediction of eruption explosivity. However, existing models, which neglect bubble‐scale magma physics, agree poorly with new experimental evidence ...

Journal of Computational Chemistry, Volume 47, Issue 21, August 5, 2026.Accelerated on‐the‐fly CC‐PIMD combines quantum ring‐polymer contraction with a CCSD/HF force decomposition to treat electron correlation and nuclear quantum effects simultaneously. For an asymmetric shared proton, NQEs reshape proton localization and induce NMR shielding changes comparable to electron correlation.

Generalized Riemann problem for a totally degenerate hyperbolic system
Electronic Journal of Differential Equations, 2018 We consider the generalized Riemann problem for the Suliciu relaxation system in Lagrangian coordinates and we calculate the first-order expansion given by LeFloch and Raviart to verify our results, then we show the explicit solution for the ...
