Analytical and Experimental Investigation of Windage–Churning Behavior in Spur, Bevel, and Face Gears

Applied Sciences
This paper presents comparable sets of the no-load power loss as a product of windage and churning behaviors of a family of various rotating parts (i.e., disc, spur gear, straight bevel gear, and orthogonal face gear).

An Experimental Investigation of Churning Power Losses of a Gearbox

Volume 10: 2017 ASME International Power Transmission and Gearing Conference, 2017
In this study, load-independent (spin) power losses of a gearbox operating under dip-lubrication conditions are investigated experimentally using a final-drive helical gear pair from an automotive transmission as the example system. A dedicated gearbox is developed to operate a single gear or a gear pair under given speed and temperature conditions.

TREX1, a predator for treating MSI‐H tumors?

Molecular Oncology, EarlyView.
Immunotherapy benefits many patients; yet, some with MSI‐H tumors remain unresponsive despite their high immunogenicity. Xu et al. reveal that TREX1 enables immune evasion by degrading cytosolic DNA and suppressing cGAS–STING–IFN‐I signaling. TREX1 loss restores DNA sensing, increases CD8+ T and NK cell infiltration, and boosts antitumor immunity ...

Testimony of John M. Abowd Before the House Committee on Energy and Commerce, Subcommitte on Commerce, Manufacturing and Trade, United States House of Representatives [PDF]

, 2012
We focus attention on gross flows in the labor market and their role in economic reallocation. Economists distinguish between movements of individuals (gross worker flows) and those associated with businesses (gross job flows). The gross worker flows are

Experimental Investigation on Churning Power Loss of Splash Lubricated Worm Gear

Periodica Polytechnica Mechanical Engineering, 2023
Churning power losses are a complex phenomenon that produces critical power losses when considering the splash lubrication of gear units. This article describes the method to investigate the churning power loss in a worm gearbox. A particular test rig was designed and fabricated to experiment on single start worm gear incompletely submerged in an oil ...

Association of Corticospinal Tract Asymmetry With Ambulatory Ability After Intracerebral Hemorrhage

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Ambulatory ability after intracerebral hemorrhage (ICH) is important to patients. We tested whether asymmetry between ipsi‐ and contra‐lesional corticospinal tracts (CSTs) assessed by diffusion tensor imaging (DTI) is associated with post‐ICH ambulation.
