Continuous Respiratory Oscillometry in Pediatric Laparoscopic Surgery—The COMET Study

Pediatric Anesthesia, EarlyView.
ABSTRACT Background Laparoscopic appendectomy is the accepted surgical approach for appendicitis in centers worldwide. Laparoscopic surgery requires the creation of a pneumoperitoneum to facilitate surgical access. Laparoscopic surgery affects the respiratory mechanics of patients under general anesthesia.

Application of Non‐Isothermal Network Theory With Curved‐Channel Element Characteristics to Predict Melt Conveying in High‐Performance Single‐Screw Extruders

Journal of Polymer Science, EarlyView.
This study presents a fast and accurate calculation tool to predict conveying of polymer melts in single‐screw extruders. Integrating generalized sub‐models into network theory allows to represent the complex screw shapes and material behavior more realistically. Tests on an industrial extruder show close agreement with experiments, outperforming older

The Hidden Costs of Coffee Production in the Eastern African Value Chains

Sustainable Development, EarlyView.
ABSTRACT There is increasing recognition that significant hidden costs associated with agrifood systems are not reflected in market prices. Coffee is among the three most traded agricultural commodities in the world and supports the livelihoods of more than 30 million smallholder households.

A Compact Annular Electrostatic Clutch Joint: Dynamic Response Modeling and Time‐Sharing Control for Underactuated Robots

SmartBot, EarlyView.
Electrostatic clutches offer programmable variable stiffness for multi‐DOF robots, but their continuous motion is usually bottlenecked by spatial constraints and detachment delays. Here, the authors report a compact annular electrostatic clutch joint with a biphasic amplitude‐frequency modulation strategy to rapidly mitigate residual polarization ...

Optimization study of pulsating heat pipe performance using taguchi method

, 2013
碩士震盪式熱管之實驗過程往往需耗費許多的時間，本研究使用田口方法減少實驗次數之特性應用於震盪式熱管；在不同控制因子與水準的搭配下進行震盪式熱管之性能最適化探討。 本研究以50%、60%、70%的填充率，0.05 /min、0.1L/min、0.15L/min的冷凝水流速與90W、120W、150W的加熱功率等為3個水準與3個控制因子，並以熱阻為品質進行L9直交表之田口方法分析。另實驗以水為工作流體，35°C恆溫水進行冷卻，蒸發區則利用加熱線圈進行加熱。分析結果顯示最佳組合為填充率60%、冷凝水流速0 ...

Intelligent Continuum Micromachines in Complex Confined Spaces

SmartBot, EarlyView.
The cover depicts a conceptual design for an intelligent continuum micromachine entering a target capsule used in fusion‐energy research through its slender gas‐fill tube. By combining route‐adaptive deformation, embedded sensing, and a functional end effector, the robot could inspect hidden defects, assess local conditions, and support localized ...

Precisely Engineering Biomimetic Nanoparticles via Controlled Cell Membrane Coating

Small, Volume 22, Issue 55, -Not available-.
Precise engineering of cell membrane‐coated nanoparticles (CMNPs) requires coordinated control over particle size, coating integrity, and membrane leaflet orientation. This review integrates key synthesis parameters, assembly strategies, and analytical methods that govern these features, revealing how structural control underpins biomimetic function ...
