For the absolute quantification of regional cerebral blood flow (rCBF) by means of H2 15 O positron emission tomography (PET) and kinetic modeling, arterial input function should be determined accurately. Even if arterial blood sampling, as an input function, provides an accurate time-activity curve (TAC), it is invasive and delay from carotid artery to radial artery should be corrected. Since ...

Controversy persists over the role of the primary somatosensory cortex (SI) in processing small-fiber peripheral afferent input. We therefore examined subject I.W, who, due to sensory neuronopathy syndrome, has no large-fiber afferents below C3 level. Cortical evoked responses were recorded with a whole-scalp neuromagnetometer to high-intensity electrical stimulation of the distal right radial,...

data envelopment analysis (dea) is a mathematical technique to evaluate the performance of firms with multiple inputs and outputs. in conventional dea models, the efficiency scores of decision making units (dmus) with non-negative inputs and outputs are evaluated in a special period of time. however, in the real world there are situations wherein performance of firms must be evaluated in multip...

Retinal fibers approach close to the tectal midline but do not encroach on the other side. Just before the entry of retinal axons into the superior colliculus (SC), a group of radial glia differentiates at the tectal midline; the spatiotemporal deployment of these cells points to their involvement in the unilateral containment of retinotectal axons. To test for such a barrier function of the te...

Background and purpose: This study was designed to compare the effectiveness of task oriented balance training program with altered sensory input versus without input. helps us choose a better for improving reducing risk fall in elderly population Subjects: Fourty eight older adults from independent life-care communities, aged 71 75 years (X = 79.2, SD 6.2), participated.Methods: Patients were ...

We investigate a discrimination method for invalid and valid spoken inquiries, received by a speech-oriented guidance system operating in a real environment. Invalid spoken inquiries include background voices, which are not directly uttered to the system, and nonsense utterances. Such spoken inquiries should be rejected beforehand. By now, we have reported a method using the likelihood values o...

We propose a new approach to measure differential radial velocities, mainly for single-lined spectroscopic binaries. The proposed procedure – TIRAVEL (Template Independent RAdial VELocities) – does not rely on a prior theoretical or observed template, but instead looks for a set of relative Doppler shifts that simultaneously optimizes the alignment of all the observed spectra. We suggest a simp...

In this paper, we present the application of the neural network for the identification of Reusable Software modules in Procedure Oriented Software System. Metrics are used for the structural analysis of the different procedures. The proposed metrics for Procedure oriented paradigm are Cyclometric Complexity Using Mc Cabe’s Measure, Halstead Software Science Indicator, Regularity Metric, Reuse f...
