We give a randomized algorithm (the ”Wedge Algorithm”) of competitiveness 3 2 Hk − 1 2k for any metrical task system on a uniform space of k points, for any k ≥ 2, where Hk = P k i=1 1 i , the k harmonic number. This algorithm has better competitiveness than the Irani-Seiden algorithm if k is smaller than 10. The algorithm is better by a factor of 2 if k < 47.

Exact inviscid theory is applied to a simple lifting configuration consisting of a wedge beneath a plane wing, both the wedge and the wing being terminated by a trailing edge which lies along a Mach cone. The efficiency of such an arrangement is compared with the efficiency of a wedge producing lift directly through incidence, as in the Nonweiler wing. The comparison is favourable to the interf...

Mount St Helens is the most active volcano within the Cascade arc; however, its location is unusual because it lies 50 km west of the main axis of arc volcanism. Subduction zone thermal models indicate that the down-going slab is decoupled from the overriding mantle wedge beneath the forearc, resulting in a cold mantle wedge that is unlikely to generate melt. Consequently, the forearc location ...

Spatial coherence of the undulator radiation in the horizontal direction is measured by a wedge-shaped crystal interferometer. The Borrmann effect, the effect of the angular divergence of the incidence and the wavefront matching of the collimating asymmetric diffractions with the interferometer are discussed to estimate the coherence factor. The spatial coherence length of 145 microm is experim...

Stability of reinforced slopes is almost always carried out using limit equilibrium methods and controlled by the shear strengths of the slope materials and the extension force of reinforcements. According to limit equilibrium methods, the stability of slopes is assessed by dividing the whole failure wedge into several vertical elements. In order to determine the safety factor of the reinforce...

Pulmonary tumor thrombotic microangiopathy (PTTM) is a fatal cancer-related complication with rapid progression. Although the underlying molecular mechanisms of PTTM remain unclear, platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) may play important roles in the pathogenesis of PTTM. We herein report a case of PTTM that was diagnosed antemortem by pathology us...

Fingerprint image quality is an important factor in the performance of Automatic Fingerprint Identification Systems(AFIS). It is used to evaluate the system performance, assess enrollment acceptability, and evaluate fingerprint sensors. This paper presents a novel methodology for fingerprint image quality measurement. We propose limited ring-wedge spectral measure to estimate the global fingerp...

The specific aim of this study was to quantify muscle activity while performing squat with technique variations. Eight healthy volunteers performed squats under 5 types of foot positions: neutral position, under a 10o descending wedge, under a 10o ascending wedge, under a 10o medial wedge and under a 10o lateral wedge. It was evaluated electromyographic data of vastus medialis oblique, vastus l...

[Purpose] This study compared the hamstring/quadriceps ratio in females during squat exercise using various foot wedges. [Subjects and Methods] Nine females participated in this study. Surface electrodes measurements were taken over the hamstring and quadriceps under 3 squat exercise conditions, and the hamstring/quadriceps ratio was calculated. [Results] The hamstring/quadriceps ratio was sign...
