We propose novel RH-metamaterial structure of the Z-chip for improving the oblique incidence characteristics as an electromagnetic wave absorber. The basic characteristics of a wave absorber using a Z-chip is calculated by FDTD simulation at an oblique incidence. To demonstrate the efficiencies of the chip, a unit cell like a Z-chip was introduced to an actual computer controlled metamaterial e...

The purpose of the study was to assess the diagnostic potential of the axial oblique view in acute ankle injury prospectively. This was an exploratory study and objectives were to determine the radiographic features that the axial oblique view demonstrates better than the mortise view. To compare axial oblique view and mortise view in fracture evaluation and assessment of ankle stability. 60 Pa...

Dong, Sheng-Jing, Paul S. Hees, Wen-Mei Huang, Sam A. Buffer, Jr., James L. Weiss, and Edward P. Shapiro. Independent effects of preload, afterload, and contractility on left ventricular torsion. Am. J. Physiol. 277 (Heart Circ. Physiol. 46): H1053–H1060, 1999.—Shortening of oblique left ventricular (LV) fibers results in torsion. A unique relationship between volume and torsion is therefore ex...

OBJECTIVE This study was undertaken to quantify the in vitro range of motion (ROM) of oblique as compared with anterior lumbar interbody devices, pullout resistance, and subsidence in fatigue. METHODS Anterior and oblique cages with integrated plate fixation (IPF) were tested using lumbar motion segments. Flexibility tests were conducted on the intact segments, cage, cage + IPF, and cage + IP...

Background: In 1991, Wright described a superior oblique expander procedure for browns syndrome and superior overaction with good results. Originally, this procedure has been performed with silicone band expander. The aim of this study was to report the results of treatment of a series of patients with Apattern strabismus associated with overacting superior oblique muscle using the fascia lata ...

The superior oblique tendon sheath syndrome was first described by Brown (I950), who noted that many cases of apparent congenital paresis of the inferior oblique muscle had restricted elevation in adduction on passive duction testing. At operation he observed thickening of the anterior part of the superior oblique tendon sheath, and whern this was stripped away a full range of passive movements...

Brainstem pathology due to infections, infarcts and tumors are common in developing countries, but neuroimaging technology in these resource-poor settings is often limited to single slice, and occasionally spiral, CT. Unlike multislice CT and MRI, single slice and spiral CT are compromised by bone artifacts in the posterior fossa due to the dense petrous bones, often making imaging of the brain...

PURPOSE To investigate the degree of reunion in rabbit eyes of the superior oblique tendon after several surgical weakening procedures. METHODS A total of 32 rabbits (64 eyes) were used in this study. The rabbits were randomly assigned to four groups, eight rabbits (16 eyes) in the tenotomy group, eight rabbits (16 eyes) in the tenectomy group, eight rabbits (16 eyes) in the disinsertion grou...

A virtual prototype of oblique rotary tilling based on SPH(Smooth Particle Hydrodynamics) was developed. Digital simulation and field test of oblique rotary tilling were conducted. The digital simulation suggested that soil mainly was torn to failure during oblique rotary tilling. Therefore, oblique rotary tilling could save energy. The given power consumption comparison of digital simulation a...

It is well known that maximal sensitivity to subtle orientation differences around a cardinal axis exceeds that around an oblique axis. In principle, this oblique effect in orientation sensitivity could either be constant across stimulus durations or could evolve as stimulus durations increase. To distinguish between these possibilities, we asked participants to judge subtle (4 deg) angular dif...
