Early maternal experience shapes offspring performance in the wild [PDF]

open access: yes, 2013
Both the environments experienced by a mother as a juvenile and an adult can affect her investment in offspring. However, the implications of these maternal legacies, both juvenile and adult, for offspring fitness in natural populations are unclear.

Flow-structure identification in a radially grooved open wet clutch by means of defocusing particle tracking velocimetry

open access: yesExperiments in Fluids, 2021
The volumetric defocusing particle tracking velocimetry (DPTV) approach is applied to measure the flow in the sub-millimeter gap between the disks of a radially grooved open wet clutch.

Adaptive Starting Control Strategy for Hybrid Electric Vehicles Equipped with a Wet Dual-Clutch Transmission

open access: yesActuators, 2023
To improve the starting performance of the P2.5 plug-in hybrid electric vehicles with a wet dual-clutch transmission, an adaptive starting control strategy is presented in this paper, which controls the two clutches simultaneously involved in the ...

On the applicability of LDV profile-sensors for periodic open wet clutch flow scenarios

open access: yesExperiments in Fluids, 2022
The present experimental study revolves around the applicability of a Bragg-shifted laser Doppler velocimetry profile sensor (LDV-PS) in use for open wet clutch flow scenarios, where sub-millimeter gap height and textured surfaces are present.

Collective cell durotaxis emerges from long-range intercellular force transmission [PDF]

open access: yes, 2016
The ability of cells to follow gradients of extracellular matrix stiffness—durotaxis—has been implicated in development, fibrosis, and cancer. Here, we found multicellular clusters that exhibited durotaxis even if isolated constituent cells did not. This

Dynamic Characteristic Analysis and Clutch Engagement Test of HMCVT in the High-Power Tractor

open access: yesComplexity, 2021
Hydromechanical continuously variable transmission (HMCVT) is capable of bearing large torque and has wide transmission range, which is suitable for high-power tractors. Dynamic characteristics could influence the tractor life, especially in a high-power

Mechanistic Study of Groove Parameters on the Thermoelastic Instability of Wet Clutch

open access: yesLubricants
The groove parameters on the friction base of wet clutches significantly affect the temperature distribution of the steel plates. However, existing methods have not thoroughly investigated the mechanisms by which these parameters influence the ...

Comparison of Various Wet-Running Multi-Plate Clutches with Paper Friction Lining with Regard to Spontaneous Damage Behavior

open access: yesTribology in Industry, 2021
Wet-running multi-plate clutches fulfill a major safety-relevant role in drive trains and, as a result, damage to and failure of the clutch system must be strictly avoided, especially spontaneous damage.

Differences in early developmental rate and yolk conversion efficiency in offspring of trout with alternative life histories [PDF]

open access: yes, 2016
Partial migration, in which some individuals of a population migrate while other individuals remain resident, is generally associated with ontogenetic shifts to better feeding areas or as a response to environmental instability, but its underlying ...
