Interpreting How Neural Networks Infer Scatterer Geometry from Echolocation Echoes

open access: yesAdvanced Intelligent Systems, EarlyView.
Neural networks enable echolocation‐based shape classification but remain difficult to interpret due to their black‐box nature. This work presents a feature‐importance metric to uncover the echo regions driving decisions in shape‐specialized networks.

Recent Advances in Stimulated Brillouin Scattering in Integrated Photonics

open access: yesAdvanced Physics Research, EarlyView.
This review systematically surveys recent advances in stimulated Brillouin scattering (SBS) within integrated photonics. It begins by elucidating the fundamental mechanisms of stimulated coupling between photons and acoustic phonons in nanoscale waveguides, enhanced by the photoelastic and moving boundary effects.

Poseidon's Sanctuary at Samikon—The Discovery of an Ancient Temple Through an Integrated Geophysical and Geoarchaeological Survey Approach for Lagoonal and Swampy Environments

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Below the classical fortress of Samikon at the coast of the western Peloponnese, ancient writer Strabo mentioned a sanctuary of Poseidon which served as the centre of the religious association of the Triphylian cities. In this paper, we describe the discovery and investigation of a building structure by means of geophysical and ...

Life cycle assessment of biodiesel synthesis from waste cooking oil using bifunctional heterogeneous catalyst

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract The development of renewable energy sources is important in order to achieve the United Nations Sustainable Development Goals (SDGs). Waste cooking oil (WCO) is a promising feedstock for biodiesel production through transesterification. Heterogeneous bifunctional catalysts offer a sustainable alternative to conventional homogeneous bases such ...

Weak Labeling-specific Emitter Identification Algorithm Based on the Weakly Supervised Wav-KAN Network

open access: yesLeida xuebao
Most existing specific emitter identification technologies rely on supervised learning, making them unsuitable for scenarios with label loss due to factors such as the acquisition environment (e.g., weather conditions, terrain, obstacles, and ...

Innovating for Net‐Zero: Collaborative and Digital Decarbonisation Strategies in Sunset Industries' Global Value Chains

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Global net‐zero ambitions require transformative strategies to decarbonise carbon‐intensive global value chains (GVCs). This study examines how multinational enterprises (MNEs) in sunset industries integrate carbon capture technologies (CCT) with operational and supply chain dynamics (OSCD) to advance decarbonisation.
