Finally on Track: Interactions of Off-Track with Plex-Sema Pathway and Glycosaminoglycans

‘On-track’ and ‘off-track’ shoulder lesions

Shoulder stability depends on the position of the arm as well as activities of the muscles around the shoulder. The capsulo-ligamentous structures are the main stabilisers with the arm at the end-range of movement, whereas negative intra-articular pressure and concavity-compression effect are the main stabilisers with the arm in the mid-range of movement.There are two types of glenoid bone loss...

Investigation of the Influences of Track Superstructure Parameters on Ballasted Railway Track Design

The main design criteria of ballasted railway tracks include rail deflections, rail bending stresses, rail wheel contact stresses, sleeper bending moments and ballast sleeper contact pressures. Numerous criteria have been defined for the design of ballasted railway tracks owing to the various mechanical properties of track components and their complex interaction. Therefore, railway track desig...

Off Track: Problems with “On Track” Inferences in Empirical and Predictive Standard Setting

Off Track: Problems with “On Track” Inferences in Empirical and Predictive Standard Setting Andrew Ho, Harvard Graduate School of Education October 24, 2012 Abstract Predictive statements about future student performance can guide the selection of a performance standard. These predictive statements often take the following form: “A student with a current score X has a P% chance of exceeding a f...

dc track edge interactions

We have developed an experimental method for investigating the interaction between two dc track edges by studying the track edge noise. We conclude that two edges do not interact when they are several micrometers apart, but the noise reduces nearly to zero when their separation is less than about half a micrometer. There is a transition region that exists between these two limits. The net track...
