Long‐Time H1$$ {H}^1 $$‐Stability of the Cauchy One‐Leg θ$$ \theta $$‐Method for the Navier‐Stokes Equations

Numerical Methods for Partial Differential Equations, Volume 42, Issue 5, September 2026.
ABSTRACT In this paper we study the long‐time stability of the Cauchy one‐leg θ$$ \theta $$‐methods for the two‐dimensional Navier‐Stokes equations. We establish the uniform dissipativity in H1$$ {H}^1 $$, in the sense that the semi‐discrete‐in‐time approximations possess a global attractor for a small enough time step, using the discrete Grönwall ...

Sampling Noise and Optimized Measurement Distribution in Imaginary‐Time Quantum Dynamics Simulations

Advanced Quantum Technologies, Volume 9, Issue 9, September 2026.
Finite‐shot sampling noise fundamentally limits the accuracy and efficiency of variational quantum algorithms on near‐term quantum devices. Using noisy simulations of variational quantum imaginary‐time evolution as a representative example, an optimized shot‐allocation strategy with a minimum‐shot constraint is shown to improve convergence, enhance ...

Discrete Boltzmann Modeling of Two‐Layer Shallow Water Flows

Water Resources Research, Volume 62, Issue 9, September 2026.
Abstract Within the framework of discrete Boltzmann modeling (DBM), a two‐layer discrete Boltzmann model (D2Q16‐2) is proposed for the simulation of shallow water flows, aiming to overcome the limitations of conventional depth‐averaged models in representing layered flow structures and the reduced numerical stability of classical lattice Boltzmann ...

Thermo‐Mechanical Controls on Central‐Vent Caldera Collapse

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 9, September 2026.
Abstract Large‐scale magmatic systems are associated with catastrophic caldera‐forming eruptions, posing hazards to millions near active volcanoes. Despite occurring across a range of sizes, the physics driving caldera collapse remain incompletely understood. While large calderas have received considerable attention, moderately sized calderas (∼5–10 km)
