Analysis of Mechanical‐Electrical‐Hydraulic Coupled Vibration Response Characteristics of Thermal Control Circulating Pumps Supported by Water‐Lubricated Bearings

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The operational reliability of thermal control circulation pumps is significantly restricted by the multi‐physics coupled environment. To reveal the vibration transmission mechanisms and dynamic response characteristics under multi‐field coupled excitations, a multi‐DOF coupled dynamic representation of the overall system, incorporating the ...

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.

Interplay Between Dispersion, Nucleation, and Crystallization in HDPE/Graphene Nanocomposites Processed Under Thermokinetic Conditions

Polymer Engineering &Science, EarlyView.
Thermokinetic processing controls graphene fragmentation and dispersion in HDPE, promoting heterogeneous nucleation and multistep crystallization. The balance between nucleation enhancement and chain mobility restriction governs the final crystalline structure and material performance.
