BACKGROUND Data describing the inhibitory effects of nitric oxide synthase (NOS) on respiratory mechanics are conflicting, and no data are available concerning possible effects on the viscoelasticity of the respiratory system, on the inspiratory work of breathing (WOB) or on respiratory system hysteresis. OBJECTIVES The aim of this study was to measure the effects of NOS inhibition by N(G)-ni...

OBJECTIVE To compare the apparent diffusion coefficient (ADC) values of upper abdominal organs with 2 different 3.0 tesla MR systems and to investigate the usefulness of normalization using the spleen. MATERIALS AND METHODS Forty-one patients were enrolled in this prospective study, of which, 35 patients (M:F, 27:8; mean age ± standard deviation, 62.3 ± 12.3 years) were finally analyzed. In a...

Ten road cut samples collected from five lithological sections of Lokoja sandstone formation in the Middle Niger basin were investigated using integrated granulometric, petrographic and geochemical analyses. Results of grain size analysis; standard deviation and skewness which ranges from 0.08 to -0.05 and 0.59 to -0.07 respectively suggest very well sorted to moderately well sorted sediments. ...

Patients receiving warfarin who have unstable control of anticoagulation have a significantly lower intake of dietary vitamin K compared with their stable counterparts. We hypothesized that supplementation with oral vitamin K would improve stability in patients with previously unstable control of anticoagulation. Seventy warfarin-treated patients with unstable anticoagulation control were rando...

The aim of this study was to investigate a method which minimizes the effects of geometric distortion on various cephalometric measurements used to determine sagittal discrepancy, such as ANB angle, Wits appraisal, AB plane angle, projections on the palatal plane, Frankfort horizontal (FH) plane, the mandibulomaxillary bisector, and the SN line, in an attempt to optimize the correlation between...

INTRODUCTION Some types of antenatal maternal psychological distress may be associated with reduced fetal growth and birthweight. A stress-mediated reduction in placental blood flow has been suggested as a mechanism. Previous studies have examined this using ultrasound-derived arterial resistance measures in the uterine (UtA) and umbilical (UA) arteries, with mixed conclusions. However, a reduc...

We consider the problem of detecting a general sparse mixture and obtain an explicit characterization phase transition under some conditions, generalizing univariate results Cai Wu. Additionally, we provide sufficient condition for adaptive optimality Higher Criticism type testing statistic formulated by Gao Ma. In course establishing these results, offer unified perspective through large devia...

We have studied Gaussian integrals before and so you should be able to show that the distribution is normalized, and that the mean and standard deviation are μ and σ respectively. The width of the distribution is σ, since the the value of P (x) at x = μ ± σ has fallen to a fixed fraction, 1/ √ e ≃ 0.6065, of its value at x = μ. The probability of getting a value which deviates by n times σ fall...

In this paper, we study the limit properties of the ratio for order statistics based on samples from an exponential distribution and obtain the expression of the density functions, the existence of the moments, the strong law of large numbers for [Formula: see text] with [Formula: see text]. We also discuss other limit theorems such as the central limit theorem, the law of iterated logarithm, t...

The recent interest in investigating the prosodic features of speech rhythm (speech timing patterns) using acoustic measurements instead of just perception has brought about several different metrics. Two of the main approaches are: (1) to compare vocalic segment (Vs) percentage against the standard deviation of consonantal segments (Cs) or (2) to compare the pairwise variability index (PVI) of...
