The high signal-to-noise ratios typical of swept-wavelength interferometry (SWI) enable distance measurements to be superresolved with 2σ uncertainties as low as 10-4-10-5 of Fourier transform-limited resolution. We compare three methods of superresolving SWI distance measurements: Local Linear Regression (LLR), Estimation of Signal Parameters via Rotational Invariance Tec...

AIM Pulmonary arteries are mainly innervated by sympathetic vasoconstrictor and parasympathetic vasodilatory fibers. We examined whether there is a relationship between the neuron densities of hilar parasympathetic ganglia and pulmonary vasospasm in subarachnoid hemorrhage (SAH). MATERIAL AND METHODS Twenty-four rabbits were divided into two groups: control (n=8) and SAH (n=16). The animals w...

Certain mutations in the unc-105 II gene of the nematode Caenorhabditis elegans have dominant effects on morphology and behavior: animals become small, severely hypercontracted and paralyzed. These unc-105 mutants revert both spontaneously and with mutagens at high frequencies to a wild-type phenotype. Most of the reversion events are intragenic, apparently because the null (loss-of-function) p...

Transient-state experiments with the obligately autotrophic Thiobacillus sp. strain W5 revealed that sulfide oxidation proceeds in two physiological phases, (i) the sulfate-producing phase and (ii) the sulfur- and sulfate-producing phase, after which sulfide toxicity occurs. Specific sulfur-producing characteristics were independent of the growth rate. Sulfur formation was shown to occur when t...

Abstract Novel organomagnesium crown ether molecules have been computationally characterized using density functional theory (DFT). Monomer units of MgC 6 are used as building blocks. Isomers H 2 extensively explored both DFT and coupled‐cluster methods in the past by some us. It had concluded that seven‐membered ring isomer, 1‐magnesacyclohept‐4‐en‐2,6‐diyne, was thermodynamically most stable ...

In this paper I investigate the System of fuzzy relation equations with inf → composition. I compare this system with the system of fuzzy relation equations with sup − ∗-composition. The purpose of this contribution is to show that there are many things which are common for both systems with sup−∗ and inf →-composition operations. K e y w o r d s: System of fuzzy relation equations; sup − ∗-com...

We prove some inf–sup and sup–inf formulae for the so–called effective multiplication factor arising in the study of reactor analysis. We treat in a same formalism the transport equation and the energy–dependent diffusion equation.

A cell culture model system has been used to study the susceptibility of cells to apoptotic cell death during different stages of neoplastic progression. This system consists of normal diploid Syrian hamster embryo (SHE) cells, two preneoplastic cell lines [tumor suppressor stage I (sup +I) and non-tumor suppressor stage II (sup -II)], and hamster tumor cell lines. Stage I preneoplastic cells a...

The uptake of guanethidine (3.3×10-5 M), debrisoquin (8.4×10-4 M), bretyliun (5.0 10-4 M) and xylocholine (1.0×10-3 M) by adrenergic neuron was studied indirectly by testing the ability of noradrenaline (NA) regarding low temp. or sodium deprivation to prevent or reverse adrenergic neuron blocking action in the indirectly stimulated ...
