Highly Efficient and Ultra‐Broadband Yellow Emission of Lead‐Free Antimony Halide toward White Light‐Emitting Diodes and Visible Light Communication

Laser & Photonics Reviews, 2022
Due to the broadband emission induced by self‐trapped excitons (STEs), low‐dimensional hybrid lead halides are regarded as an emerging class of highly efficient light emitters. However, the toxic lead element impedes their commercial application. Here, a

PSO Algorithm on PAPR Reduction Performance of Asymmetrically Clipped Optical‐OFDM

Applied Computational Intelligence and Soft Computing, Volume 2026, Issue 1, 2026.
This research presents a novel hybrid optimization framework combining artificial neural networks (ANN) and particle swarm optimization (PSO) to mitigate the high peak‐to‐average power ratio (PAPR) in asymmetrically clipped optical‐orthogonal frequency division multiplexing (ACO‐OFDM) systems. While conventional PTS effectively reduces PAPR, it suffers

Cranial Defect Reconstruction With Custom 3D‐Printed Hydroxyapatite Scaffolds Augmented With rhBMP‐2 or Dipyridamole in a Nonhuman Primate Model

Journal of Tissue Engineering and Regenerative Medicine, Volume 2026, Issue 1, 2026.
Objective Reconstruction of critical‐sized bone defects, particularly in the cranio‐maxillofacial region, presents unique challenges due to the need for integration with adjacent well‐vascularized tissue and the absence of significant load‐bearing requirements.

Chemotherapy Under Fire: Narratives of Patients With Cancer During Wartime

Psycho-Oncology, Volume 34, Issue 11, November 2025.
ABSTRACT Study objective Patients with cancer living in regions of war face significant quality of life (QoL)‐related concerns, both cancer‐ and war‐related. This study examined the correlation between narratives of patients referred to an integrative oncology (IO) program in northern Israel and heart rate variability (HRV) measurements.

SPICE Modeling of GaN MicroLEDs for Optical Communication

Journal of the Society for Information Display, Volume 33, Issue 10, Page 1030-1045, October 2025.
Unified Gallium Nitride (GaN) µLED model: a new small‐signal approach integrated with static models enables accurate circuit‐level simulation of optical links (Figure a). Implemented in SPICE and validated experimentally, the model shows excellent agreement (Figure b), offering a compact and practical tool for next‐generation communication systems ...

Analysis of visible light communication (VLC)for biomedical application

International Journal of Engineering & Technology, 2018
In the visible light communication (VLC), light emitting diodes (LEDs) are used as transmitters; the air is the transmission medium and the photodiodes are used for receivers. This is often referred to as light fidelity (Li-Fi). In this method, provide the methodology to evaluate the performance of VLC hotspot networks in the context of data ...
