Motor Vehicle Brake Pad Wear—A Review

Vehicles
The paper offers an overview of the motor vehicle brake pad wear process. Considering the types of wear that occur between the pads and the disc, the study begins by presenting Archard’s fundamental wear law. It explains how the hardness and roughness of

Auto‐Downregulation of the Florigen FT Production Prevents Precocious Flowering in Plants

Advanced Science, EarlyView.
This study shows that the leaf vein‐expressed FD complexes with the florigen FT to bind DNA motifs in FT promoter, which antagonizes CONSTANS‐mediated FT activation to feedback down‐regulate FT expression. This prevents an excessive induction of FT expression by inductive photoperiods, thereby precluding precocious transition to flowering in ...

Inverse Design of Pre‐Strain via a Predictive Electromechanical Model for Enhanced Strain Sensing

Advanced Science, EarlyView.
An analytical electromechanical model rooted in microcrack evolution mechanics is globally calibrated from only eight pre‐strain datasets, enabling prediction of the complete sensing response at untested pre‐strain values within the calibrated design space (R2 > 0.99).

A numerical and experimental study on the factors that influence heat partitioning in disc brakes [PDF]

, 2010
YesTo investigate the heat partition on a vehicle disc brake, a small scale test rig with one contact interface was used. This allowed the disc/pad contact temperatures to be measured with fast-response foil thermocouples and a rubbing thermocouple ...

Cold wear of brake disc related to brake induced vibrations

International Journal of Vehicle Noise and Vibration, 2005
The cold wear of brake disc is a phenomenon related to judder and other kinds of vibrations. The mechanism and the parameters concerning the cold wear of the disc are the basis for the comprehension of the sources of brake induced vibrations. As a continuation of prior research, a tribometric study was conducted with different disc materials: grey cast

The BTB/POZ‐MATH Protein ZmBPM1 Interacts With Autophagy‐related Protein ZmATG6 and Modulates the NLR Protein Rp1‐D21‐Mediated Defense Response in Maize

Advanced Science, EarlyView.
The maize BTB/POZ‐MATH (BPM) protein ZmBPM1 interacts with autophagy‐related protein ZmATG6 to relocate the NLR protein Rp1‐D21 from the nucleo‐cytoplasmic compartment into autophagosome‐like puncta, leading to autophagy‐mediated turnover and suppressing the hypersensitive response.
