Optical coherence tomography (OCT) has recently become one of the primary methods for noninvasive probing human retina. The pseudoimage formed by OCT (the so-called B-scan) varies probabilistically across pixels due to complexities in measurement technique. Hence, sensitive automatic procedures diagnosis using may exploit statistical analysis spatial distribution reflectance. In this paper, we perform a study retinal data. We find that stretched exponential probability density function can...
Abstract. A patient with a thymic carcinoid tumour causing ectopic ACTH syndrome is presented. The case illustrates the rapid development of clinical and laboratory findings often associated secretion ACTH, including severe proximal myopathy, emotional lability, hypokalaemic alkalosis. Interpretation conventional tests pituitary-adrenal function was complicated by intermittent tumour. results selective venous sampling for ruled out pituitary hypersecretion were suggestive source;...
A method of realization a linear time-invariant system based on the moments impulse-response matrix is proposed. For this purpose some characteristics matrices are set forth. Then given which makes it possible to construct minimal realization.
This electron microscopic study was primarily of 2 aspects rat liver carcinogenesis induced by chronic diethylnitrosamine (DENA) administration. An abnormality initially DENA in the hepatocytes an increase volume smooth endoplasmic reticulum (SER) form tubules and vesicles. Between 49 70 days from initial administration, small foci were found that differed distinctly others because absence or greatly reduced SER. system also lacking tumors, observed between 91 122 days, but present increased...
Experimental and numerical investigations have been performed in order to study the effect of welding parameters on properties FSW-ed AZ31 magnesium alloy sheets. The results, presented terms tensile strength field variables distributions, allow understand behaviour such material when using different rotational speeds for a given tool geometry.
A respiratory chamber is used for monitoring O(2) consumption (Vo(2)), CO(2) production (Vco(2)), and quotient (RQ) in humans, enabling long term (24-h) observation under free-living conditions. Computation of Vo(2) Vco(2) currently done by inversion a mass balance equation, with no consideration measurement errors other uncertainties. To improve the accuracy results, new mathematical model suggested present study explicitly accounting presence such uncertainties error sources use optimal...
Incubation of anterior pituitary glands female rats with 10-5M vincristine or colchicine reduced both synthesis and release prolactin. perphenazine-treated male blocked the perphenazine-induced increase in vitro prolactin synthesis. At 10-4M, inhibited growth hormone by untreated but could not block dibutyryl cyclic AMP-induced stimulation release. 10 μg/ml cytochalasin B resulted decreased drug significantly hormone. Concomitant electron microscopic observations indicated that cytoplasmic...
ABSTRACT In this work we face the Routing problem defined as an optimal control problem, with variables representing percentages of each flow routed along available paths (multi‐path routing), and a set cost functions corresponding to two different objectives traffic balancing bottleneck load minimization. A key issue considered in paper is possibility splitting given network sub‐networks, one controlled by separate subset variables. This course designs decomposition original...
Abstract. The realization of the additive manufactured components requires understanding variables having an effect on physical final geometry. One them is represented by initial digital information with required tolerance, in particular where different parts such as planar and curved ones need to be connected together. other important variable extruding conditions FDM PLA blend materials. temperature setting which reduce induced tensions, volume variation warpage determined.
Cells of nickel sulfide-induced rhabdomyosarcomas were studied with the electron microscope. in proliferative compartment mononucleate and exhibited neither myofilaments nor other features normal muscle cell differentiation. nonproliferative had differentiated similarly to fetal early postnatal cells. The tumor cells did not differentiate beyond initial stage formation triads smooth endoplasmic reticulum. Transitional forms between undifferentiated observed. Only a fraction progeny dividing...
