Exploring the 3D Gravity Inversion Problem Using a Compact Hybrid Transformer‐Based Deep Learning Model

open access: yesJournal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract The three‐dimensional (3D) gravity inversion problem is the process of delineating the volumetric mass distributions from the surface gravity anomalies. Recently, many innovative Convolutional Neural Network (CNN) based algorithms have found some success in reduction of computation costs and delineation of sharper boundaries of causative ...

Ant-colony-based multiuser detection for multifunctional-antenna-array-assisted MC DS-CDMA systems

open access: yes, 2008
A novel Ant Colony Optimization (ACO) based Multi-User Detector (MUD) is designed for the synchronous Multi-Functional Antenna Array (MFAA) assisted Multi-Carrier Direct-Sequence Code-Division Multiple-Access (MC DS-CDMA) uplink (UL), which supports both

Future‐Making From Afar: Digital Twins in Medicine

open access: yesSociology of Health &Illness, Volume 48, Issue 5, June 2026.
ABSTRACT Digital twins in medicine are packaged as inevitable, disruptive technologies that will revolutionise healthcare, yet their integration into clinical practice remains slow. In this article, we extend current research on digital twins by shifting attention to the actors behind the technology and their visions.

Description, Articulation and Limitations in the Social Theory of Insurance

open access: yesThe British Journal of Sociology, Volume 77, Issue 3, Page 496-506, June 2026.
ABSTRACT There have been surprisingly few sustained efforts to explain or theorise the role insurance plays in society. Even the most theoretically inflected insurance scholarship, emanating from governmentality and Actor Network Theory scholarship, tends to be grounded in empirical cases, set in particular periods and places, and it is often ...

Multi-point path planning based on the algorithm of colony-particle swarm optimization

open access: yesTongxin xuebao, 2019
The problem of multi-point path planning is a NP-hard problem,which is equivalent to finding the shortest path of a starting point and some specific node.Aiming at the problem of multi-point path planning,a retrospective ant colony-particle swarm ...

New Heuristics for Stable LDA Parameter Search

open access: yesComputational Intelligence, Volume 42, Issue 3, June 2026.
ABSTRACT The Latent Dirichlet Allocation (LDA) algorithm automatically extracts latent topics from a textual corpus, but configuring its parameters can be difficult and time‐consuming. Optimization algorithms can help determine the best parameters, but not necessarily the optimal ones.
