Small but mighty: Impact hazards from iron Near‐Earth Objects
Meteoritics &Planetary Science, Volume 61, Issue 2, Page 224-240, February 2026.Abstract Small asteroids can impact Earth unexpectedly, as demonstrated by the Chelyabinsk event in 2013. The warning times are likely to be short, and the first tools for fast hazard predictions have been developed in the last years for encounters with rocky or cometary objects, which quickly fragment in the atmosphere and cause airbursts. However, in

Witt groups of sheaves on topological spaces
, 2007 This paper investigates the Witt groups of triangulated categories of sheaves (of modules over a ring R in which 2 is invertible) equipped with Poincare-Verdier duality.

Entrepreneurship as strategic network creation: A relational practices perspective
European Management Review, Volume 22, Issue 4, Page 972-994, December 2025.Abstract Often entrepreneurship may be more about the strategic creation of an interorganizational network than of an organization. Based on a revelatory case study from a rather traditional industry in a vibrant entrepreneurial ecosystem, we argue that once startups replace organization creation by means of network creation they are confronted with a ...

A note on the cohomology of moduli spaces of local shtukas
Bulletin of the London Mathematical Society, Volume 57, Issue 12, Page 3709-3729, December 2025.Abstract We study localized versions of spectral action of Fargues–Scholze, using methods from higher algebra. As our main motivation and application, we deduce a formula for the cohomology of moduli spaces of local shtukas under certain genericity assumptions, and discuss its relation with the Kottwitz conjecture.

Holomorphic field theories and higher algebra
Bulletin of the London Mathematical Society, Volume 57, Issue 10, Page 2903-2974, October 2025.Abstract Aimed at complex geometers and representation theorists, this survey explores higher dimensional analogs of the rich interplay between Riemann surfaces, Virasoro and Kac‐Moody Lie algebras, and conformal blocks. We introduce a panoply of examples from physics — field theories that are holomorphic in nature, such as holomorphic Chern‐Simons ...

Food Science &Nutrition, Volume 13, Issue 9, September 2025.X‐ray micro‐CT allows accurate morphological olive fruit and stone phenotyping for quality monocultiivar olive oil traceability. Stone extremity traits mainly influence variety classification, but also internal ones. Bhattacharyya coefficient of trait discriminant functions helps in variety distinctness while Support Vector Machine provides best olive ...

The Shi variety corresponding to an affine Weyl group
Bulletin of the London Mathematical Society, Volume 57, Issue 3, Page 913-940, March 2025.Abstract Let W$W$ be an irreducible Weyl group and Wa$W_a$ its affine Weyl group. In this article we show that there exists a bijection between Wa$W_a$ and the integral points of an affine variety, denoted X̂Wa$\widehat{X}_{W_a}$, which we call the Shi variety of Wa$W_a$.

Double Copy From Tensor Products of Metric BV■‐Algebras
Fortschritte der Physik, Volume 73, Issue 1-2, February 2025.Abstract Field theories with kinematic Lie algebras, such as field theories featuring color–kinematics duality, possess an underlying algebraic structure known as BV■‐algebra. If, additionally, matter fields are present, this structure is supplemented by a module for the BV■‐algebra.
