The Kobayashi pseudodistance on almost complex manifolds [PDF]
, 1997 We extend the definition of the Kobayashi pseudodistance to almost complex manifolds and show that its familliar properties are for the most part preserved.

Graph potentials and topological quantum field theories
Proceedings of the London Mathematical Society, Volume 132, Issue 4, April 2026.Abstract We introduce a new functional equation in birational geometry, whose solutions can be used to construct two‐dimensional topological quantum field theories (2d TQFTs), infinite‐dimensional in many interesting examples. The solutions of the equation give rise to a hierarchy of graph potentials, which, in the simplest setup, are Laurent ...

Journal of Geophysical Research: Planets, Volume 131, Issue 1, January 2026.Abstract We investigated the regolith parent rock (“protolith”) properties of Mare Tranquillitatis and Marius Hills on the Moon, utilizing lunar pit craters (“lua”) to contextualize observations of rock abundance and crater degradation. We discovered a significant difference in underlying materials: the region around the Tranquillitatis lua is ...

Entomologia Experimentalis et Applicata, Volume 174, Issue 1, Page 37-44, January 2026.This study demonstrated that the host essential oil significantly reduced Polygraphus proximus Blandford (Coleoptera: Scolytinae) attack density, but the density did not differ significantly among logs of various lengths of Abies sachalinensis. Our study suggests that host essential oils can perform as repellents against conifer‐infesting bark beetles.

Exotic holomorphic Engel structures on C4
, 2017 A holomorphic Engel structure determines a flag of distributions $\mathcal{W}\subset \mathcal{D}\subset \mathcal{E}$. We construct examples of Engel structures on $\mathbf{C}^4$ such that each of these distributions is hyperbolic in the sense that it has

Symmetric products and puncturing Campana‐special varieties
Proceedings of the London Mathematical Society, Volume 131, Issue 6, December 2025.Abstract We give a counterexample to the Arithmetic Puncturing Conjecture and Geometric Puncturing Conjecture of Hassett–Tschinkel using symmetric powers of uniruled surfaces, and propose a corrected conjecture inspired by Campana's conjectures on special varieties.

BL46XU: an applied hard X‐ray photoelectron spectroscopy beamline HAXPES II at SPring‐8
Journal of Synchrotron Radiation, Volume 32, Issue 6, Page 1578-1585, November 2025.The BL46XU beamline at SPring‐8 has been restructured for hard X‐ray photoelectron spectroscopy (HAXPES), featuring two specialized HAXPES instruments and advanced X‐ray optics for high‐throughput and ambient‐pressure measurements. This article outlines the beamline design, performance and recent scientific achievements enabled by these upgrades.The ...
