We show theoretically that range of reflection bands and defect modes inside the band gap can be tuned by using a one-dimensional tilted photonic crystal (TPC) structure. A TPC structure is similar to the conventional PC structure with the only difference that in this case alternate layers are inclined at certain angle in the direction of periodicity of the structure. In order to obtain the ref...

PURPOSE To evaluate patellar kinematics of volunteers without knee pain at rest and during isometric contraction in open-and closed-kinetic-chain exercises. METHODS Twenty individuals took part in this study. All were submitted to magnetic resonance imaging (MRI) during rest and voluntary isometric contraction (VIC) in the open and closed kinetic chain at 15 degrees, 30 degrees, and 45 degree...

Dimerization of single-pass membrane receptors is essential for activation. In the human thrombopoietin receptor (TpoR), a unique amphipathic RWQFP motif separates the transmembrane (TM) and intracellular domains. Using a combination of mutagenesis, spectroscopy, and biochemical assays, we show that W515 of this motif impairs dimerization of the upstream TpoR TM helix. TpoR is unusual in that a...

Dislocations govern the properties of crystals. Yet, how pentagon–heptagon (5|7) pairs in grain boundaries (GBs) affect mechanical MoS2 remains poorly known. Using atomistic simulations and continuum disclination dipole model, we show that depending on tilt angle 5|7 dislocation arrangement, GB strength can be enhanced or reduced with angle. For zigzag-tilt GBs primarily composed Mo5|7 + S5|7 d...

CONCLUSION The antero-posterior (AP) body tracking test (BTT) showed that the dominant foot could affect the tilt angle of the sway movement, delineated by primary component analysis. Differences associated with the dominant foot could represent the difference in space perception of each person. OBJECTIVES To examine whether the dominant foot could affect the postural control mechanism using ...

OBJECTIVE To make a comparative analysis on three femoropatellar radiographic parameters, between knees with chronic failure of the anterior cruciate ligament (ACL) and normal knees. METHODS Thirty volunteer patients with a diagnosis of unilateral isolated chronic ACL injury for more than one year and a normal contralateral knee were selected. Digital radiographs were produced for all the pat...

In this study, we present a new calibration method for the cooperation of wide-angle and pan-tilt-zoom (PTZ) cameras. A wide-angle camera enables the surveillance of a large area. However, it may be difficult to perceive the detail of an object. On the other hand, a PTZ camera enables the surveillance of the object detail. However, its view is limited when the camera zooms on a specific object....

Generalizations of the well-known Bassetti and Erskine formula to include tilt angle and non-Gaussian particle distributions, as well as centroid deflections, are derived.

In the present investigation, basic studies were conducted using an inclined pin-on-plate sliding tester to understand the influence of tilt angle and grinding marks direction of the plate on coefficient of friction and transfer layer formation during sliding against soft aluminium (Al) pin. 080 M40 steel plates were ground to attain different surface roughness with unidirectional grinding mark...

A dose of 5.0310 antimony (Sb) ions cm was implanted into silicon wafers at an energy of 70 keV, at different tilt angles ~0°, 15°, 30°, 45°, and 60°!. One set of samples was preamorphized with 160 keV germanium (Ge) ions with a dose of 1310 cm. The second set consisted of implants into single crystal silicon. After implantation the samples were annealed at 700 °C for 30 s in a pure nitrogen am...
