Reaching for Ancestral Heritage: Sakha Collections in the Museums of the World

open access: yesMuseum Anthropology, Volume 49, Issue 1, Spring 2026.
ABSTRACT This paper is devoted to the collections of old Sakha objects produced by Indigenous craftsmen in the north of the Russian Empire and now located in many museums around the world. For several centuries, objects representing Sakha material culture were taken away from their place of origin by explorers, scholars, collectors, and missionaries ...

Kauzmann Paradox, Supercooling, and Finding Order in Chaos

open access: yesAngewandte Chemie, Volume 137, Issue 10, March 3, 2025.
80 years later: Kauzmann temperature (Tk), and associated entropy catastrophe/paradox remains an enigma for nearly 80 years without any unifying resolution. Potential resolutions to the Kauzmann paradox, however, have so far been limited in the existence of an equilibrium ideal glass transition and traditional description of phase transition. Continued

Toric amplitudes and universal adjoints

open access: yesJournal of the London Mathematical Society, Volume 113, Issue 2, February 2026.
Abstract A toric amplitude is a rational function associated with a simplicial polyhedral fan. The definition is inspired by scattering amplitudes in particle physics. We prove algebraic properties of such amplitudes and study the geometry of their zero loci. These hypersurfaces play the role of Warren's adjoint via a dual volume interpretation.

Physicochemical Characterization of Solid Catalysts: Morphological, Structural, Textural, Reducibility, and Acid‐Base Insights

open access: yesChemCatChem, Volume 17, Issue 23, December 8, 2025.
This review provides a practical guide for the characterization of solid catalysts, emphasizing key techniques such as SEM, TEM, XRD, Raman spectroscopy, and gas physisorption. It also covers reducibility and acid‐based analyses through TPR, TPD, and FTIR.

Holomorphic field theories and higher algebra

open access: yesBulletin 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 ...

Comparison of Mandelshtam's Conditions with Convergence Conditions for Iterative Procedures in the Analysis of Complex Dynamic Systems by Means of Partial Models

open access: yesEngineering Transactions, 1992
The convergence conditions for iterative procedures in the analysis of dynamic systems with the use of partial models are compared with Mandelshtam's conditions (uncoupling of vibrations of partial models). Both basic iteration procedures are discussed.

Global Lunar Boulder Map From LRO NAC Optical Images Using Deep Learning: Implications for Regolith and Protolith

open access: yesJournal of Geophysical Research: Planets, Volume 130, Issue 7, July 2025.
Abstract Boulders on the lunar surface indicate relatively recent surface activity, related to mass wasting or bedrock excavation by impact cratering, and degrade over time, producing regolith. Previously, the distribution of boulders was indirectly assessed using the anisothermality effects observed by the Lunar Reconnaissance Orbiter (LRO) Diviner ...
