Canal Lock Displacement

Median nerve displacement through the carpal canal.

We determined the direct relationships between wrist position and displacement of the median nerve during active contraction of the flexor tendons at the wrist with an intact, transected transverse carpal ligament (TCL). Nine fresh cadavers were mounted in an apparatus to allow variable wrist position. Excursions of the tendons and displacement of the median nerve were measured by tracking mark...

Exaggerated displacement of the atrioventricular canal towards the bulbus cordis (rightward displacement of the mitral valve).

Seven malformed hearts in which a common feature seems to be an exaggerated displacement of the atrioventricular canal towards the bulbus cordis, i.e. the future right ventricle, are described. Transposition or malposition of the great arteries and a ventricular septal defect existed in 6 patients. Certain comparisons are established between previously described entities with which these cases ...

RH Lock: A Scalable Hierarchical Spin Lock

Scalable architectures with non-uniform memory access time (NUMAs) have gained increased popularity in recent years. The increased scalability have increased the demand for scalable lock implementations, such as the queue-based locks of Mellor-Crummey and Scott (MCS lock), and of Craig, Landin and Hagersten (CLH lock). This paper demonstrates that the first-come first-served nature of queue-bas...

Sensitivity of the Root Canal Impedance to Electrode Displacement – in vivo and in vitro Measurement

Root canal impedance measurement was carried out in vivo on a series of patients and in vitro on a model (tooth dipped into a saline solution). Impedance was measured for several file tip displacements from apical foramen in the frequency range from 100 Hz to 1 MHz. Comparison between in vivo and in vitro results was performed for the measured value of impedance and for the components (Rp, Cp) ...
