Cascaded multilevel control of DSTATCOM using multiband hysteresis modulation [PDF]

, 2006
In this paper a cascaded H-bridge inverter topology is used in a distribution static compensator (DSTATCOM). A new multiband hysteresis algorithm is used to control the switches of the cascaded H-bridges leading to multilevel output of the inverter.

A Dual‐Bioresponsive and Programmable Microneedle Matrix as a Bioinspired Coupler for Orchestrating Diabetic Bone Regeneration

Advanced Materials, EarlyView.
This project developed a smart bandage‐like patch (a microneedle array) for repairing diabetic bone damage. It intelligently senses signals from infection and inflammation, then releases its medicines in a specific, timed sequence: first an antibacterial agent, then an anti‐inflammatory agent, and finally growth factors.
