Demographic Dynamics and International Trade: Stylized Facts and Theoretical Insights

open access: yesJournal of Economic Surveys, Volume 40, Issue 4, Page 1806-1833, September 2026.
ABSTRACT Demographic change within a country has economic repercussions for other countries through international transactions. Ongoing shifts in population size and age structure across countries have important implications for international trade, operating through changes in market size, consumption preferences, and labor supply.

Adaptive and Robust Control of Diamond Quantum Sensors via Meta‐Learning

open access: yesAdvanced Quantum Technologies, Volume 9, Issue 8, August 2026.
Quantum Meta‐Learning: Meta‐learning frameworks address pulse transferability in NV‐center quantum sensing. By training on diverse tasks that simulate experimental variations, robust surrogate models are created that rapidly adapt to new scenarios without extensive recalibration.

The Ramsey theory of the universal homogeneous triangle-free graph [PDF]

open access: yesJournal of Mathematical Logic, 2020
The universal homogeneous triangle-free graph, constructed by Henson [A family of countable homogeneous graphs, Pacific J. Math. 38(1) (1971) 69–83] and denoted [Formula: see text], is the triangle-free analogue of the Rado graph. While the Ramsey theory of the Rado graph has been completely established, beginning with Erdős–Hajnal–Posá [Strong ...

The Legacy of Policy Inaction in Climate‐Growth Models

open access: yesInternational Economic Review, Volume 67, Issue 3, Page 915-935, August 2026.
ABSTRACT To better understand the structure and core mechanisms of a broad class of climate‐growth models, we study a simplified version of the dynamic integrated model of climate and the economy (DICE) through the lens of growth theory. We analytically show that this model features a continuum of saddle‐point stable steady states.

Riboflavin Salvage Supports Glycolysis in Borrelia burgdorferi Through Flavin‐Dependent NAD+ Regeneration

open access: yesMolecular Microbiology, Volume 126, Issue 2, Page 208-219, August 2026.
The Lyme disease agent Borrelia burgdorferi has limited metabolic capabilities and depends on salvage of riboflavin via the BB0316‐BB0319 transport system for generation of critical flavin cofactors FMN and FAD. Riboflavin is important for NAD+ regeneration to fuel glycolysis.

Composite Ramsey theorems via trees

open access: yesDiscrete Analysis
Composite Ramsey theorems via trees, Discrete Analysis 2026:4, 17 pp. A famous unsolved problem in Ramsey theory, asked by Neil Hindman, is the question of whether if the natural numbers are finitely coloured, one can find $x$ and $y$ such that $x, y, x+

On a Ramsey–Turán variant of Roth's theorem

open access: yesBulletin of the London Mathematical Society, Volume 58, Issue 8, August 2026.
Abstract A classical theorem of Roth states that the maximum size of a solution‐free set of a homogeneous linear equation L$\mathcal {L}$ in Fp$\mathbb {F}_p$ is o(p)$o(p)$ if and only if the sum of the coefficients of L$\mathcal {L}$ is 0. In this paper, we prove a Ramsey–Turán variant of Roth's theorem, with respect to a natural notion of “structured”

Monochromatic Graph Decompositions Inspired by Anti-Ramsey Theory and Parity Constraints

open access: yesMathematics
We open here many new tracks of research in anti-Ramsey Theory, considering edge-coloring problems inspired by rainbow coloring and further by odd colorings and conflict-free colorings. Let G be a graph and F any given family of graphs. For every integer
