Si‐Based GeSn Lateral p–i–n Waveguide Photodetectors Covering Entire Short‐Wave Infrared Band
Advanced Photonics Research, Volume 7, Issue 3, March 2026.This work introduces a complementary metal‐oxide‐semiconductor (CMOS)‐compatible GeSn lateral p–i–n waveguide photodetector monolithically integrated on a silicon platform. Enabled by a high‐quality, and high‐Sn‐content GeSn active layer, the developed GeSn photodetector achieves photodetection covering the entire short‐wave infrared band for ...

Advanced Science, Volume 13, Issue 16, 18 March 2026.Resorbable impedance sensors are successfully implanted into porcine small intestinal anastomoses. Impedance was recorded for 2 hours prior, and 2 hours following ischemia induction, and a significant drop in tissue impedance was observed. Abstract Anastomotic failure remains one of the most severe complications in gastrointestinal surgery.

Demystifying Piecewise and Localized Scatter Correction Methods
Journal of Chemometrics, Volume 40, Issue 3, March 2026.ABSTRACT Multiplicative scatter is a common source of noise in near‐infrared spectroscopy and other related instrumental techniques. A wide variety of methods are commonly used for the correction of multiplicative scatter. However, the majority of such methods assume that the parameters that describe the scatter are constant throughout the measured ...
