At present, there is no standard or research to define the specific length of entrance and exit sections an undersea tunnel. In combination with unique longitudinal slope tunnel change in illumination difference, lengths lane change, transition adaptation were theoretically deduced, a model for was established. Considering Qingdao Jiaozhou Bay as experimental subject, accuracy section verified ...

An analysis of electrocardiograms from a patient with spontaneous double irregular ventricular parasystole is presented. Irregularity in one of the two parasystoles was produced by intermittence based on rate-dependent (phase 3) entrance block, and in the other parasystole it was attributed to "supernormal" exist conduction. Critical analysis of electrocardiograms revealed that first degree blo...

We give computable bounds on the rate of convergence of the transition probabilities to the stationary distribution for a certain class of geometrically ergodic Markov chains. Our results are different from earlier estimates of Meyn and Tweedie, and from estimates using coupling, although we start from essentially the same assumptions of a drift condition towards a “small set”. The estimates sh...

At operation for the correction of cubitus varus by removal of a wedge based laterally, the radial nerve fortunately was first explored and found to run through a transverse bony tummel at the posterior level of a suprocondylar fracture sustained eight years previously. After elevation of the bony tunnel and nerve en bloc the osteotomy was completed; neurapraxia of the radial nerve soon recover...
