Bayesian inverse ensemble forecasting for COVID‐19

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Variations in strains of COVID‐19 have a significant impact on the rate of surges and on the accuracy of forecasts of the epidemic dynamics. The primary goal for this article is to quantify the effects of varying strains of COVID‐19 on ensemble forecasts of individual “surges.” By modelling the disease dynamics with an SIR model, we solve the ...

Invariant Measure and Universality of the 2D Yang–Mills Langevin Dynamic

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We prove that the Yang–Mills (YM) measure for the trivial principal bundle over the two‐dimensional torus, with any connected, compact structure group, is invariant for the associated renormalised Langevin dynamic. Our argument relies on a combination of regularity structures, lattice gauge‐fixing and Bourgain's method for invariant measures ...

Sudan at War With Itself: Civilian Devastation in the Civil War

open access: yesConflict Resolution Quarterly, EarlyView.
ABSTRACT A civil war is raging in Sudan between the Sudan Armed Forces (SAF) and the Rapid Support Forces (RSF) along with militia groups. Beginning on April 15, 2023, and continuing at least to this writing (October 15, 2025), civilian noncombatants have been subjected to bombings, beatings, torture, shootings, rape, and murder on a large scale. Since

Chaos communication system based on time index chaotic shape-forming filter

open access: yesTongxin xuebao
In order to improve the energy efficiency of chaotic signals generated by chaotic shape-forming filters, a chaotic communication system was proposed based on time indexed chaotic shape-forming filters. In this system, time index modulation was applied in
