Influence of Facility Size on Perioperative Outcomes in Minimally Invasive Esophagectomy for 14 152 Patients With Esophageal Cancer Based on the Japanese National Clinical Database: A Multicenter Cohort Study

Annals of Gastroenterological Surgery, EarlyView.
This multicenter study investigated 14 152 minimally invasive esophagectomies (MIEs) using data from the Japanese National Clinical Database and showed a significantly lower operative mortality rate in high‐volume centers than in low‐volume centers. However, no differences in morbidity rates were found between facility sizes.

Rapid and Reversible Morphing to Enable Multifunctionality in Robots

Advanced Intelligent Systems, EarlyView.
This article introduces a rapid, reversible, and repeatable morphing robot through a bistable latch‐mediated, spring actuated (LaMSA) mechanism. This enables an untethered, multifunctional robot to near‐instantaneously (< 50 ms) and reversibly switch between a flying and driving configuration to navigate through different environments.

Morphy: A Compliant and Morphologically Aware Flying Robot

Advanced Intelligent Systems, EarlyView.
This study presents Morphy, a 25.2 cm‐wide, 260 g aerial robot with flexible, sensorized joints that enable it to withstand high‐speed collisions and squeeze through narrow spaces. Powered by an adaptive control scheme exploiting real‐time morphology feedback, Morphy demonstrates resilience in trajectory tracking, collision, and impact recovery and ...
