Field‐Driven Active Colloids as Distributed Micromachines: Bridging Physics, Control, and Function Across Length Scales

Advanced Science, EarlyView.
Field‐driven active colloids are framed as distributed micromachines in which externally supplied power, sensing, and control regulate task‐relevant states. By closing the loop between particle behavior, imaging, computation, and electric or magnetic actuation, these systems can progress from programmable motion toward adaptive functional outcomes ...

Impact of Mode Decision Delay on Estimation Error in Continuous-Time Controlled System

IEEE Access, 2018
For highly maneuvering target interception in terminal guidance, the maximal admissible mode decision delay (MAMDD) and the least required mode sojourn time (LRMST) are calculated in continuous-time controlled system.

Radical Resection of the Third Portion of the Duodenum for Secondary Aortoduodenal Fistula

Annals of Gastroenterological Surgery, EarlyView.
Secondary aortoduodenal fistula most commonly involves the third portion of the duodenum and requires definitive management of both vascular and gastrointestinal components. We demonstrate a step‐by‐step technique for radical duodenal resection and reconstruction performed in structured collaboration with cardiovascular surgeons.
