Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.Abstract Mantle convection drives the solid Earth, powering plate motions, volcanism, and earthquakes while regulating planetary heat loss. Reconstructing its history is hampered by sparse, noisy observations concentrated near the surface and the present day. Here I develop an inverse physics‐informed neural network framework to estimate mantle thermal

The Legacy of Policy Inaction in Climate‐Growth Models
International 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.

A description of the projective Stone algebras [PDF]
Glasgow Mathematical Journal, 1983 In his book [6] Grätzer sets a guideline for the research on Stone algebras; in view of his and Chen's triple characterization of Stone algebras [3], he considers a problem for these algebras solved if it can be reduced to a problem for Boolean algebras and one for distributive lattices with 1.

A Comparative Review of Specification Tests for Diffusion Models
International Statistical Review, Volume 94, Issue 2, Page 347-381, August 2026.Summary Diffusion models play an essential role in modelling continuous‐time stochastic processes in the financial field. Therefore, several proposals have been developed in the last decades to test the specification of stochastic differential equations.

Saturated boolean algebras and their stone spaces
Topology and its Applications, 1985 For \(\kappa\geq \omega\), a Tychonoff space X is called \(\kappa\)- Parovichenko if (1) X is compact and zero-dimensional, and (2) the Boolean algebra CO(X) of clopen subsets of X is \(\kappa\)-saturated and satisfies \(| CO(X)| =\kappa^{

The Role of Dice in the Emergence of the Probability Calculus
International Statistical Review, Volume 94, Issue 2, Page 464-483, August 2026.Summary The early development of the probability calculus was clearly influenced by the roll of dice. However, while dice have been cast since time immemorial, documented calculations on the frequency of various dice throws date back only to the mid‐13th century.

A class of projective Stone algebras [PDF]
Bulletin of the Australian Mathematical Society, 1981 We prove that a regular double Stone algebra is protective in the category of Stone algebras if and only if its centre is a projective Boolean algebra and its dense set is countably generated as a filter. It follows that every countable regular double Stone algebra is projective as a Stone algebra.
