Advanced Quantum Technologies, Volume 8, Issue 10, October 2025.It is shown how to use EPR, using electron spins as qubits, coupled with each other by the exchange interaction, to set the configuration of n qubits (n = 1–4) at resonance, in conjunction with pulses, to construct the varius Toffoli gates, to build a quantum computer.

A Deep Generative Model for the Simulation of Discrete Karst Networks
Earth and Space Science, Volume 12, Issue 10, October 2025.Abstract The simulation of discrete karst networks presents a significant challenge due to the complexity of the physicochemical processes at their origin, occurring within various geological and hydrogeological contexts over extended periods. This complex interplay leads to a wide variety of karst network patterns, each intricately linked to specific ...

Water Resources Research, Volume 61, Issue 10, October 2025.Abstract Simulation‐optimization methods are commonly used in groundwater pollution source identification. Traditional simulation‐optimization methods require multiple calls to the numerical model, which leads to a considerable computational burden.

Solving three core challenges in transient dynamics analysis of matrix population models
Methods in Ecology and Evolution, Volume 16, Issue 10, Page 2517-2530, October 2025.Abstract Populations are at the mercy of random disturbances, large and small, and rarely, if ever, converge on predicted long‐term behaviours. Therefore, when using matrix population models, ecologists study the dynamics of populations that depart from stable distributions.

Computer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 24, Page 4093-4111, 6 October 2025.Abstract Rail defects significantly impact train operations, even posing serious safety risks. Existing methods can automatically collect images from the rail surface and identify apparent defects while facing challenges such as high false positive rates, visually subtle defects omit errors, and quantitative defect size measurement.

Lagrange multiplier selection based on SATD for H.265/HEVC
Tongxin xuebao, 2017 In order to improve the coding performance of intra rough mode decision,a SATD-based Lagrange multiplier selection algorithm was proposed for H.265/HEVC.The characteristic of Hadamard transform was first analyzed,and following the new Lagrange multiplier

Moments, sums of squares, and tropicalization
Journal of the London Mathematical Society, Volume 112, Issue 4, October 2025.Abstract We use tropicalization to study the duals to cones of nonnegative polynomials and sums of squares on a semialgebraic set S$S$. The truncated cones of moments of measures supported on the set S$S$ are dual to nonnegative polynomials on S$S$, while “pseudomoments” are dual to sums of squares approximations to nonnegative polynomials.
