Automated and Efficient Sampling of Chemical Reaction Space

Advanced Science, Volume 12, Issue 9, March 6, 2025.
The paper presents an efficient method for sampling chemical reaction space to train machine learning interatomic potentials (MLIPs). By combining fast tight‐binding calculations with selective high‐level refinement, the approach generates diverse datasets capturing both equilibrium and reactive regions.

Predicting underwater unmanned vehicle dynamic recovery process in nonlinear watershed based on BP neural network

Xibei Gongye Daxue Xuebao
Because of a nonlinear watershed′s interference during the recovery of an unmanned underwater vehicle (UUV), a closed-loop control method for optimizing the recovery path of the UUV based on the BP neural network is proposed.

The Production of Ultra High Energy Cosmic Rays during the Early Epochs of Radio-loud AGN

, 2011
Powerful radio-loud active galactic nuclei (AGN) with large Mpc-scale jets have been theoretically motivated as emitters of high-energy cosmic rays. Recent radio observations have established a populous class of young radio-loud galaxies with compact ($<

Research on the Combined Detection of Magnetic Anomaly and Shaft‐Rate Magnetic Field Signals

IET Radar, Sonar &Navigation, Volume 19, Issue 1, January/December 2025.
Magnetic anomaly signal, shaft‐rate magnetic field signal, combined detection. ABSTRACT Due to the stable propagation of magnetic signals in ocean and air, magnetic detection technology has become an effective means for nonacoustic detection. The magnetic anomaly signal and shaft‐rate magnetic signal radiated by underwater vehicles are currently the ...

Robustness of spin filtering against current leakage in a Rashba-Dresselhaus-Aharonov-Bohm interferometer

, 2013
In an earlier paper [Phys. Rev. B 84, 035323 (2011)], we proposed a spin filter which was based on a diamond-like interferometer, subject to both an Aharonov-Bohm flux and (Rashba and Dresselhaus) spin-orbit interactions.

Pose‐graph underwater simultaneous localization and mapping for autonomous monitoring and 3D reconstruction by means of optical and acoustic sensors

Journal of Field Robotics, Volume 41, Issue 8, Page 2543-2563, December 2024.
Abstract Modern mobile robots require precise and robust localization and navigation systems to achieve mission tasks correctly. In particular, in the underwater environment, where Global Navigation Satellite Systems cannot be exploited, the development of localization and navigation strategies becomes more challenging.

New error measures and methods for realizing protein graphs from distance data

, 2016
The interval Distance Geometry Problem (iDGP) consists in finding a realization in $\mathbb{R}^K$ of a simple undirected graph $G=(V,E)$ with nonnegative intervals assigned to the edges in such a way that, for each edge, the Euclidean distance between ...
