Extensions of Rayleigh–Bloch waves above the cutoff frequency are studied via discrete spectrum a transfer operator for channel containing single cylinder with quasi-periodic side-wall conditions. Above cutoff, wavenumber becomes complex valued and an additional appears. For small- to intermediate-radius values, extended shown connect Neumann Dirichlet trapped modes before embedding in continuo...

The errors of radius and wall thickness of a single vessel due to oblique sectioning in histomorphometry are expressed as a function of the circular shape factor (CSF) of the section's lumen, assuming cylindrical geometry and the absence of tissue deformation. Using computer model trees generated by constrained constructive optimization, mean errors are estimated for an ensemble of vessel segme...

A finite ultraviolet cutoff near a reflecting boundary yields a stress tensor that violates the basic energy-pressure relation. Therefore, a " soft " wall described by a power-law potential , which needs no ad hoc cutoff, is being investigated by the collaboration centered at Texas A&M University and the University of Oklahoma. Progress is reported here. 1.1. Basic formalism and empty space We ...

background abnormalities in the velocity and pattern of myocardial shortening on tissue doppler imaging (tdi) have been proposed to aid in the noninvasive diagnosis of coronary artery disease (cad). objectives we investigated the diagnostic value of post-systolic shortening (pss), a delayed ejection velocity of the myocardium after the closure of the aortic valve, on tdi in the diagnosis of cad...

this research was conducted at torogh agricultural research station in khorasan-e razavi province to determine the impact of irrigation cutoff at different growth stages and percentage of water use on the yield and water use efficiency (wue) of wheat cultivars using sprinkler irrigation. the study was done from 2006-2008. the experimental design was a randomized complete block design with a str...

In the far north of Uttar Pradesh Province in the Indian Himalayas; the 280 MW Dhauliganga hydroelectric power plant is under construction by National Hydroelectric Power Corporation ( NHPC ), a stateowned enterprise; and a joint venture of Kajima Corporation of Tokyo and Daewoo Corporation of Seoul. This project sets out to develop the lower section of the mountain cascade of the Dhauliganga r...

By introducing the generalized uncertainty principle (GUP) on quantum density states, we newly obtain a consistent entropy of a scalar field on the (1+1)-dimensional Maxwell-dilaton background without an artificial cutoff in contrast to the results of the brick wall model, which depend on the choice of the Hawking temperature for the extremal case.
