Intelligent reflecting surface (IRS) is a promising technology for channel readjustment. In this letter, we investigate the simultaneous lightwave information and power transfer (SLIPT) technique deployed visible light communication (VLC) system, implement SLIPT by adjusting association between optical IRS (OIRS) transceivers to maximize harvested energy while guaranteeing achievable data rate. Further, binary assignment matrix introduced represent behavior mentioned above, then problem...
Abstract Flexible crystals that can capture solar energy and convert it into mechanical are promising for a wide range of applications such as information storage actuators, but obtaining them remains challenge. Herein, an elastic crystal barbiturate derivative was found to be excellent candidate, demonstrating plastic bending behavior under natural sunlight irradiation. 1 H NMR high‐resolution mass spectrum data microcrystals before after light irradiation demonstrated light‐induced [2+2]...
Faced with growing demands for high-speed and reliable communication systems, optical intelligent reflecting surfaces (OIRS) have recently attracted a lot of interest in visible light (VLC). With potential applications variety scenarios, including indoor wireless communications the Internet Things (IoT), OIRS is expected to transformative impact on communications. However, current research predominantly theoretical, hardware implementation insufficient. Therefore, this paper introduces an...
This paper investigates the problem of distributed fault detection in a class interconnected nonlinear uncertain systems. It significantly extends previous results by considering more general Under certain assumptions, method is developed, and adaptive thresholds for derived, ensuring robustness with respect to interconnections among subsystems modeling uncertainty. Moreover, detectability conditions are rigorously investigated, characterizing detectable process faults sensor each subsystem....

<title>Abstract</title> Cryo-electron microscopy (cryo-EM) single-particle analysis (SPA) has revolutionized structural biology, enabling the efficient determination of structures at atomic or near-atomic resolutions. However, a common challenge arises from severe imbalance among various conformations vitrified particles, leading to low-resolution reconstructions in rare due lack particle images these quasi-stable states. To address this limitation, we introduce CryoTRANS, method that...
Background: Roxithromycin (RXM), a macrolide antibiotic, exhibits anti-asthmatic effects, but its specific mechanism of action remains elusive. We evaluated the effects RXM on airway inflammation, expression calprotectin, and activity receptor advanced glycation end products (RAGE) to determine whether alleviates inflammation by regulating RAGE activation, thereby calprotectin expression, in neutrophilic asthma.Methods: Male Brown Norway rats were sensitized with ovalbumin (OVA) Freund's...
