Reforming Export Control Regimes: Addressing Emerging Technologies Through Responsible Innovation

Global Policy, EarlyView.
ABSTRACT The proliferation of dual‐use emerging technologies—such as artificial intelligence (AI), quantum computing, and additive manufacturing—poses a growing challenge for multilateral export control regimes. Designed for tangible goods and slower innovation cycles, existing arrangements increasingly struggle to govern technologies that are ...

A novel elite guidance-based social learning particle swarm optimization algorithm

Xibei Gongye Daxue Xuebao
To improve the premature convergence and poor global search capability of the classical particle swarm algorithm(PSO), this paper proposes a novel elite guidance-based social learning particle swarm optimization (ESLPSO) algorithm.

Between Hedging and Bandwagoning: E3 and Iran's Nuclear Program From the JCPOA to the 2026 “Ramadan War”

Global Policy, EarlyView.
ABSTRACT This article examines the evolution of the European Troika's narratives on Iran's nuclear program, from the aftermath of the JCPOA to the 2026 “Ramadan War.” Drawing on an analysis of 55 official statements by E3 leaders and diplomats, the study traces how the E3 shifted between a posture of normative hedging and one of bandwagoning.

Power Allocation Scheme for Multi-Static Radar to Stably Track Self-Defense Jammers

Remote Sensing
Due to suppression jamming by jammers, the signal-to-interference-plus-noise ratio (SINR) during tracking tasks is significantly reduced, thereby decreasing the target detection probability of radar systems.

High Accuracy and Unambiguous 2D-DOA Estimation With an Uniform Planar Array of “Long” Electric-Dipoles

IEEE Access, 2018
For the polarization sensitive array considered in the most current literature, the physical length of the electric-dipole is less than 0.1 of a wavelength, and the radiation efficiency of this “short”electric-dipole is too low.

An Overview of the Rock Art of AlUla: Tracing Changes in Content and Form Across 12,000 Years of Human History

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT Between 2018 and 2021, the Identification and Documentation of Immovable Heritage Assets (IDIHA) Project recorded over 19,000 rock art panels in the AlUla (al‐‘Ulā) region of north‐western Saudi Arabia. This study presents a chronological assessment of the corpus, drawing on superimpositions, datable motifs, inscriptions, and varnish formation,

Embodied Narrations: Video Narrative Inquiry for Meaning‐Making of Learning Contexts

International Journal of Art &Design Education, EarlyView.
Abstract This text begins with the initial question of how we can narrate in a situated and meaningful way about the processes of teaching and learning, not to repeat what we imagine that we should say and already know, but to be truthful with respect to the issues that affect us and matter to us.
