Software‐Defined Terahertz Beam Manipulation via Active Light‐Controlled Frequency Coding Information Metasurface

Advanced Physics Research, EarlyView.
This paper proposes an integrated active light‐controlled frequency coding metasurface and a software‐defined array control system. Utilizing spatially encoded structured light and a “Decision‐Optimization‐Execution” intelligent closed‐loop architecture, the system overcomes traditional electrical control interference, achieves real‐time dynamic ...

Toroidal‐Dipole‐Driven Polarization‐Selective Quasi‐BICs Enabling Wide‐Angle Near‐Field Image Display in Dielectric Metasurfaces

Advanced Physics Research, EarlyView.
This study presents toroidal‐dipole (TD)‐driven polarisation‐selective quasi‐bound states in the continuum (quasi‐BICs) in all‐dielectric metasurfaces, enabling transverse magnetic (TM)‐selective excitation with ultrahigh quality factors and wide‐angle‐stable polarisation‐dependent near‐field imaging.

Interconversion of Optical to Terahertz Pulses in Nonlinear Beta Barium Borate Crystal

Advanced Physics Research, EarlyView.
ABSTRACT Low‐temperature β‐phase barium borate (β‐BBO) is an important nonlinear crystal, widely utilized for optical second‐harmonic (SH) generation. Recent re‐measurements of refractive indices in the terahertz (THz) range reveal that β‐BBO is a positive uniaxial crystal.

A compatibility criterion for optimal control and information aggregation in hierarchical network systems

Asian Journal of Control, EarlyView.
Abstract Large swarms often adopt a hierarchical network structure that incorporates information aggregation. Although this approach offers significant advantages in terms of communication efficiency and computational complexity, it can also lead to degradation due to information constraints.

Too Hot to Profit? Climatic Stress and Farm‐Level Performance in Italian Viticulture

Business Strategy and the Environment, EarlyView.
ABSTRACT This paper investigates the economic impact of long‐run climatic conditions on Italian wine farms by applying a Ricardian framework to 1431 firms from the 2022 RICA‐FADN survey. We combine farm‐level revenues with viticulture‐specific agroclimatic indicators to assess how climate stress shapes profitability across 77 Italian NUTS3 provinces ...

Internalization of Management Systems and Eco‐Product Innovation: The More the Better?

Business Strategy and the Environment, EarlyView.
ABSTRACT Environmental challenges demand urgent and strategic responses from firms. Eco‐product innovation (EPI) is a key approach to reducing environmental impact while preserving competitiveness. This research analyses the relationship between EPI and the internalization of management system (MS) certifications, focusing on ISO 9001, ISO 14001, and ...

Ensemble‐based soil liquefaction assessment: Leveraging CPT data for enhanced predictions

Civil Engineering Design, Volume 7, Issue 1, Page 23-35, March 2025.
Abstract This study focuses on predicting soil liquefaction, a critical phenomenon that can significantly impact the stability and safety of structures during seismic events. Accurate liquefaction assessment is vital for geotechnical engineering, as it informs the design and mitigation strategies needed to safeguard infrastructure and reduce the risk ...
