Analysis of Load and Lubrication State of Racks and Pinions of Three Gorges Ship Lift Based on Actual Service Conditions

open access: yesJixie chuandong, 2023
The rack and pinion of the three gorges ship lift is a low speed and heavy load open gear transmission with hard tooth surface. Once the lubrication is poor, it is easy to cause damage such as tooth surface scuffing, which will affect the operation ...

Inhibition and potentiation of the exercise pressor reflex by pharmacological modulation of TRPC6 in male rats

open access: yesThe Journal of Physiology, Volume 603, Issue 18, Page 5027-5052, September 15, 2025.
Abstract figure legend The majority of L4–L5 dorsal root ganglion cells innervating the triceps surae muscles of healthy rats expressed TRPC6 channels. In decerebrated rats, pharmacological inhibition of TRPC6 channels by injection of antagonists (SAR7334 or BI‐749327) into the arterial supply of the triceps surae muscles inhibited the exercise pressor

Lactate and hydrogen ions play a predominant role in evoking the exercise pressor reflex during ischaemic contractions but not during freely perfused contractions

open access: yesThe Journal of Physiology, Volume 603, Issue 18, Page 5053-5070, September 15, 2025.
Abstract figure legend The role of lactate and hydrogen ions in evoking the metabolic component of the exercise pressor reflex was studied in rats with either a functional pygm gene (pygm+/+) or with a non‐functional “knocked out” pygm gene (pygm−/−). The pygm gene is responsible for producing the myophosphorylase enzyme which catalyses the breakdown ...

Untethered Autonomous Holonomic Mobile Micromanipulator for Operations in Isolated Confined Spaces

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 8, August 2025.
Herein, a lightweight (515 g), compact (10 cm3), untethered holonomic mobile micromanipulator powered by piezoelectric actuators is presented. It autonomously manipulates mm to sub‐mm objects and droplets in narrow, hazardous spaces, achieving 0.18 ± 0.51 mm positioning accuracy and −0.4° ± 1.2° angular deviation.

Complex Assemblies of Colloidal Microparticles with Compliant DNA Linkers and Magnetic Actuation

open access: yesAdvanced Materials Technologies, Volume 10, Issue 8, April 17, 2025.
High‐surface‐energy polycarbonate templates are used to assemble polystyrene microspheres, improving yields more than 100‐fold. These higher yields facilitate the construction of active colloids and complex microstructures, including 10‐sphere microrotors and a 26‐sphere “CMU.” These active colloids are connected with compliant DNA linkages, enabling ...

Solar drum positioner mechanisms [PDF]

open access: yes, 1982
The need for additional power on spinning satellites required development of deployable solar arrays activated, as on a 3-axis vehicle, after separation from a booster or shuttle orbiter. Mechanisms were developed for telescopically extending a secondary

A Soft Robotic Textile‐Actuated Anthropomorphic Artificial Shoulder Mechanism

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 4, April 2025.
This article describes the concept, development, and applications of anthropomorphic, artificial shoulder mechanism that is actuated by soft robotic textile. By mimicking the structural and functional aspect of the shoulder, the mechanism has been demonstrated to serve as a gesture‐controlled robot and advanced testing dummy for human augmentation ...
