Beyond Reputation: A Function for CSR in the Age of Systemic Crises. Evidence From the Italian Business Landscape

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Corporate Social Responsibility (CSR) and Corporate Sustainability (CS) are historically distinct constructs that have converged to the point of conceptual confusion. This paper operates within the CSR tradition, arguing that authentic CS is structurally impossible without the ethical foundation CSR provides.

Localized 3D acoustic streaming in microdroplets using high‐frequency micro‐beam IDTs

Droplet, EarlyView.
Miniaturized 160 MHz acoustic microbeam transducers, with a size much smaller than droplets, enable precise localized actuation, generating complex three‐dimensional streaming and tunable particle aggregation. This concept provides high‐resolution, non‐contact fluid manipulation for biosensing, lab‐on‐chip diagnostics, and targeted drug screening ...

Real‐time lithology identification while drilling based on drill cuttings image analysis with ensemble learning

Deep Underground Science and Engineering, EarlyView.
A lithology identification while drilling method was developed, integrating an automated cuttings sampling system, a smart drilling rig, and an ensemble learning model. Underground trials achieved 97.42% accuracy in real‐time identification of cuttings lithology and composition, enhancing hazard management and supporting unmanned drilling technology in

Gaborlet‐guided sparse filtering: A novel intelligent method for lithology identification by vibration signals while drilling

Deep Underground Science and Engineering, EarlyView.
The flowchart illustrates rock specimen testing, vibration signal acquisition, and feature extraction with Gaborlet and sparse filtering for classification. Abstract Traditional lithology identification methods mainly rely on core sampling and well‐logging data.
