How data market drives regional energy efficiency? —Quasi-natural experimental evidence from China by Xiaoxi Cao, Yiye Zhang

“…Employing the quasi-natural experiment afforded by the data trading platform, we construct a difference-in-differences (DID) model to investigate the impact of DM on energy efficiency. The key points: (1) DM exerts a favorable influence on regional energy efficiency, a relationship robustly confirmed through rigorous testing procedures; (2) DM facilitates improvements in energy efficiency by shaping the decision-making processes of enterprises and influencing environmental behaviors at the governmental level; (3) the efficacy of DM manifests more prominently in regions characterized by pronounced information asymmetries; (4) DM exhibits spatial effects, extending its influence across regional boundaries to impact energy efficiency levels. …”

Ultrafast dynamics in tailored VCSEL cavity geometry toward high-efficiency physical random number generation by Hang Lu, Omar Alkhazragi, Heming Lin, Tien Khee Ng, Boon Ooi

“…In this study, for the first time, we explored how cavity geometry impacts chaotic dynamics in vertical-cavity surface-emitting lasers (VCSELs) to optimize their performance as high-efficiency entropy sources. By comparing circular, D-shaped, and pentagonal cavity designs, we demonstrate that the pentagonal geometry significantly enhances multimode interactions by introducing more modes overlapping in the space and spectrum, thereby driving strong mode competition and ultrafast chaotic lasing dynamics, which allow for an ultra-high-speed random number generation (RNG) rate of 800 Gb/s with minimal post-processing, approaching the physical limits of measurement systems. …”
