MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

Advanced Electronic Materials, EarlyView.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...

Long-Time Coherent Integration Method for Passive Bistatic Radar Using Frequency Hopping Signals

Sensors
Long-time coherent integration using frequency hopping signals is a challenging problem for passive bistatic radar due to its frequency hopping characteristics. Apart from range walk, range curve, and Doppler frequency migration, Doppler diffusion caused

Fluorescence Guided Surgery in Gastric Cancer: What Do We Have and What Can We Do?

Annals of Gastroenterological Surgery, EarlyView.
ABSTRACT Background and Objective Fluorescence imaging has emerged as a valuable adjunct in gastric surgery, enhancing resection precision and oncologic outcomes. However, the use of indocyanine green (ICG) remains controversial due to uncertainties in efficacy and administration. A lack of standardized protocols persists.
