Imperial uses of non‐territorial autonomy: The projects of André Mandelstam and Boris Nolde

Nations and Nationalism, Volume 31, Issue 2, Page 431-446, April 2025.
Abstract The article explores imperial uses of non‐territorial autonomy in the works of international lawyers André Mandelstam and Boris Nolde, which they wrote before the collapse of the Russian Empire. Although written in different contexts, their projects for non‐territorial autonomy departed from other similar plans proposed in the Russian Empire ...

On isomorphisms between quiver Yangians

Journal of High Energy Physics
Quiver Yangians are infinite-dimensional algebras capturing the BPS structure of a large class of supersymmetric models. Quiver theories related by Seiberg duality are expected to have isomorphic quiver Yangians, and this isomorphism has previously been ...

Slopes of Lunar Crater Size‐Frequency Distributions on Exterior Impact Melt Deposits of Young Craters

Journal of Geophysical Research: Planets, Volume 130, Issue 3, March 2025.
Abstract Lunar impact craters can be used as a tool to derive information about the timing and sequence of the emplacement of geologic units and surface processes on the Moon. The production function (PF) derived from crater size‐frequency distribution (CSFD) measurements is an essential component in determining the model age of a geologic surface. The

DDF amplitudes are lightcone amplitudes and the naturalness of Mandelstam maps

European Physical Journal C: Particles and Fields
We show that on-shell DDF amplitudes are on-shell lightcone amplitudes and that Mandelstam maps emerge naturally with a precise normalization, and are intrinsic to the DDF states. Off-shell DDF and Mandelstam amplitudes à la Kaku–Kikkawa differ.

Embracing uncertainty: porous and actionable responses to climate change at the borders of Indigenous and scientific expertise(s) in Siberia

Journal of the Royal Anthropological Institute, Volume 31, Issue 1, Page 63-81, March 2025.
Abstract This article explores uncertainty as an onto‐epistemological concept that reveals integrative capacities of Indigenous and scientific knowledge. Looking at official scientific approaches to climate change in Russia, it traces how Indigenous peoples in Siberia navigate their lives as they continue to witness anthropogenic causes of climatic ...

Investigation into the effect of phenylalanine gating on anaerobic haem breakdown using the energy landscape approach

Protein Science, Volume 34, Issue 2, February 2025.
Abstract We have recently demonstrated a novel anaerobic NADH‐dependent haem breakdown reaction, which is carried out by a range of haemoproteins. The Yersinia enterocolitica protein, HemS, is the focus of further research presented in the current paper.

Large N master field optimization: the quantum mechanics of two Yang-Mills coupled matrices

Journal of High Energy Physics
We study the large N dynamics of two massless Yang-Mills coupled matrix quantum mechanics, by minimization of a loop truncated Jevicki-Sakita effective collective field Hamiltonian.

Complexity of quadratic quantum chaos

Journal of High Energy Physics
We investigate minimal two-body Hamiltonians with random interactions that generate spectra resembling those of Gaussian random matrices, a phenomenon we term quadratic quantum chaos.

An analytic zeta function ramp at the black hole Thouless time

Journal of High Energy Physics
Black hole normal modes have intriguing connections to logarithmic spectra, and the spectral form factor (SFF) of E n = log n is the mod square of the Riemann zeta function ζ(s).
