From Clinic to Computation: Multiscale Bioengineering Strategies for Durable Biological Aortic Valve Replacements

Advanced Functional Materials, EarlyView.
Bioprosthetic aortic valves have revolutionized the treatment of aortic stenosis, but their durability is limited by structural valve deterioration (SVD). This review focuses on the pericardial tissue at the heart of these valves, examining how its mechanical properties and calcification drive fatigue and failure.

A 120 GHz Hybrid Low Noise Amplifier in 40 nm CMOS

IEEE Access
In this paper, we present a 6-stage 120 GHz hybrid low noise amplifier (LNA) for sub-THz radar systems. To enhance the noise figure (NF) and gain performance of the LNA, we propose a hybrid architecture that utilizes a combination of 2-stage single-ended
