Risk Measure Duality Without Structure
Mathematical Finance, EarlyView.ABSTRACT We study risk measures on vector spaces of random variables which a priori have little structure, such as spaces lacking law invariance or a lattice structure. Ensuring the existence of a tractable dual representation (one which does not contain non‐sigma‐additive measures) is one of the main problems in risk measure theory, and we address it ...

Metroeconomica, EarlyView.ABSTRACT The Kurz–Salvadori eigenequation concerns Sraffian closed, single‐product–circulating capital economies and determines the unique economically relevant profit rate and price vector that correspond to an exogenously given money wage rate. This paper approaches the Kurz–Salvadori eigenequation as a (semi‐)positive rank‐one matrix perturbation of

Assessing the Effectiveness of Workers' Selection Exams: The Case of the Bank of Italy
Oxford Bulletin of Economics and Statistics, EarlyView.ABSTRACT High‐stakes exams can be used to rank and select candidates for job openings, and the ability of those selected hinges on the design of the exam. I propose a method to model candidates' performance to assess how effective the exam is at selecting high‐ability candidates.

Global Change Biology Communications, Volume 1, Issue 4, December 2026.The Gulf of Alaska (GOA) has experienced multiple marine heatwaves (MHWs) from 2014 to 2016 and 2019. Pacific cod hatch timing advanced by 2–4 weeks during and adjacent to MHWs (2018, 2020) at Eastern Kodiak Island, and a persistent southwest gradient with cooler waters, later hatching, and smaller changes in hatch timing during warming was present ...

NMR in Biomedicine, Volume 39, Issue 12, December 2026.Non‐negative geographically weighted regression separates tissue‐specific metabolic signals in MRSI while correcting for partial‐volume effects. Coupled with anatomical segmentation, it enables spatial interpolation of metabolite maps with realistic intratissue heterogeneity.

Arbitrary Lagrangian–Eulerian Formulation in a Rotating Frame to Model Friction Spinning
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT Friction spinning is a metal forming process that can be used to manufacture various shapes by rotating a metallic workpiece relative to a blunt tool. When used as a hot metal forming process, the relative velocity between workpiece and tool is increased until substantial heat is generated due to friction.

The Long Shadow of Karl Weierstraß Over the Calculus of Variations
Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.
