A unified formulation for home healthcare routing and scheduling problems

International Transactions in Operational Research, EarlyView.
Abstract Home Healthcare is an essential component of healthcare systems, where caregivers visit patients' homes to deliver services. While presenting advantages with respect to institutional care, such as being cost‐effective and alleviating family burdens, it presents challenges in scheduling and routing caregivers efficiently.

A hybrid robust‐stochastic optimization approach for green hydrogen production planning under wind power forecast uncertainty

International Transactions in Operational Research, EarlyView.
Abstract This work aims at minimizing the energy purchase costs related to the operation of a green hydrogen production plant connected both to an intermittent, uncertain renewable energy source and to the power grid. We focus on scenarios where, for economic or environmental reasons, the plant must primarily meet hydrogen demand using electricity from

Assessing the Impact of Urbanization on Grasshopper Behaviour—A Fieldwork Approach

Journal of Applied Entomology, EarlyView.
ABSTRACT Urbanization is one of the most significant land‐use changes globally, profoundly impacting biodiversity across taxa. Insects, including grasshoppers (Orthoptera), are particularly sensitive to urban pressures, often exhibiting both morphological and behavioural adaptations.

The Staircase Chart: Visualising Vertical and Cross‐Shelf Movements and Dispersal of Early‐Life Fish, Applied to Japanese Jack Mackerel

Fisheries Oceanography, Volume 35, Issue 5, Page 689-703, September 2026.
ABSTRACT Dispersal during early life stages is a critical process shaping marine fish connectivity and population dynamics, yet direct field observations at the individual level remain elusive. This has limited our understanding of the factors controlling dispersal, including the impact of active swimming by larvae and juveniles. Here, we present a new

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

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

Structure and Computation

Noûs, Volume 60, Issue 3, Page 593-605, September 2026.
ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

Degradation‐aware energy management for photovoltaic‐storage‐charging microgrids under extreme operating environments: A comprehensive review

Energy Conversion and Economics, Volume 7, Issue 4, Page 293-311, August 2026.
Abstract Photovoltaic‐storage‐charging microgrids (PSCMs) are being increasingly deployed in extreme environments, including desert, polar, coastal and high‐altitude regions, to provide a reliable and sustainable power supply. However, these harsh environments significantly accelerate the degradation of photovoltaic arrays, battery storage systems and ...

The Insect Calculator: A web tool to predict meadow arthropods based on mowing impacts

Ecological Solutions and Evidence, Volume 7, Issue 3, July–September 2026.
Although the biodiversity crisis and insect decline have gained increasing scientific and public attention, they persist, indicating that current measures are insufficient. The Insect Calculator (insektentaschenrechner.de/en), a digital tool that models and visualises the effects of mowing and environmental parameters on arthropod density and species ...

Expansion of invasive carabids across elevation and habitats on sub‐Antarctic South Georgia

Insect Conservation and Diversity, Volume 19, Issue 4, Page 812-827, July 2026.
Two introduced carabid species have continued to expand their ranges on the sub‐Antarctic island of South Georgia over the past 10–15 years. The species have colonised inland valleys and are present across habitats but are more abundant in those with high vegetation cover. N‐mixture models revealed the optimal sampling method, intensity and habitat for

An Account of Luck, Fortune, and Fate

Philosophy and Phenomenological Research, Volume 113, Issue 1, Page 16-28, July 2026.
ABSTRACT Luck is one of our most important concepts. In this article, I first argue that extant accounts of luck are deeply flawed. I then argue for a hybrid account of luck that is based around the difference between skill‐based and non‐skill‐based events.
