A Multi‐Resonant Tunable Fabry‐Pérot Cavity for High Throughput Spectral Imaging

Advanced Optical Materials, Volume 13, Issue 8, March 13, 2025.
This study introduces a multi‐resonant tunable Fabry‐Pérot filter for high throughput spectral imaging. With a spectral resolution of 10 nm and a switching time of 23 ms, this compact and low‐cost device possesses better spectral imaging accuracy in poor light conditions while maintaining over six times higher optical throughput than standard liquid ...

Advancing All‐Day Passive Radiative Cooling Performance of 3D Anodized Aluminum Oxide Nanostructures on Aluminium

Advanced Optical Materials, EarlyView.
Advanced anodic aluminium oxide (AAO) nanostructures incorporate interconnections between the vertical pores, forming a 3D‐AAO nanonetwork that functions as a Bragg reflector. By varying the periodicity of the transverse channels, the light‐matter interaction can be tuneable to enhance their emissivity and passive radiative cooling performance across ...

Synchronous robotic networks and complexity of control and communication laws [PDF]

arXiv, 2005
This paper proposes a formal model for a network of robotic agents that move and communicate. Building on concepts from distributed computation, robotics and control theory, we define notions of robotic network, control and communication law, coordination task, and time and communication complexity. We then analyze a number of basic motion coordination

The Role of Theoretical Calculations for INVEST Systems: Complementarity Between Theory and Experiments and Rationalization of the Results

Advanced Optical Materials, EarlyView.
Theoretical lessons are key for molecules presenting an inverted singlet‐triplet excited state (e.g. S1 and T1) energy difference. This perspective provides a snapshot of the role played by calculations in last years, not only to anticipate experimental findings but also for driving high‐throughput virtual screenings, as well as the main challenge to ...

Community Detection for Heterogeneous Multiple Social Networks [PDF]

arXiv
The community plays a crucial role in understanding user behavior and network characteristics in social networks. Some users can use multiple social networks at once for a variety of objectives. These users are called overlapping users who bridge different social networks.
