Perovskite‐based time‐domain signal‐balancing LiDAR sensor with centimeter depth resolution

open access: yesInfoMat, EarlyView.
In this study, we present a monolithic high‐speed perovskite‐based photodetector capable of directly sensing the time delay between two light pulses with a temporal resolution of at least 170 ps. This outstanding time resolution is achieved through a signal‐balancing detection scheme that effectively overcomes the limitations of conventional ...

Evaluation of Acute Exposure to Combustible and Novel Tobacco Products Using an In Vitro Human Airway Organ Tissue Equivalent Model

open access: yesJournal of Applied Toxicology, EarlyView.
ABSTRACT Despite the well‐known risks of tobacco use, tobacco exposure remains a major contributor to morbidity and mortality worldwide. Although cigarette use has declined, the popularity of novel tobacco products (NTPs), such as electronic cigarettes (ECs) and heated tobacco products (HTPs), has increased.

Admission Plasma Lipopolysaccharide‐binding protein, Procalcitonin, and Lactate for Early Identification of Nosocomial Infection in Cirrhotic Patients With Upper Gastrointestinal Bleeding: A Retrospective Analysis

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study aimed to assess whether admission plasma lipopolysaccharide‐binding protein (LBP), procalcitonin (PCT), and lactate could improve detection of nosocomial infection in cirrhotic patients presenting with upper gastrointestinal bleeding (UGIB).

Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform

open access: yesLaser &Photonics Reviews, EarlyView.
Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Topological Photonic Devices and Circuits at Terahertz Frequencies

open access: yesLaser &Photonics Reviews, EarlyView.
This review examines how 3D topological insulators and emerging topological photonic phases enable robust, low‐loss and defect‐immune terahertz devices. Fundamental properties, device implementations and topological transport mechanisms are surveyed, revealing new opportunities for reconfigurable, high‐performance THz components and scalable ...
