Genetic Evidence for Sites of Interaction Between the Gal3 and Gal80 Proteins of the <i>Saccharomyces cerevisiae GAL</i> Gene Switch (2008)

Galactose-activated transcription of the Saccharomyces cerevisiae GAL genes occurs when Gal3 binds the Gal4 inhibitor, Gal80. Noninteracting variants of Gal3 or Gal80 render the GAL genes noninducible. To identify the binding determinants for Gal3's interaction with Gal80 we carried out GAL3-GAL80 intergenic suppression analyses and selected for new GAL3 mutations that impair the Gal3-Gal80 interaction. We show that a GAL3(C)-D368V mutation can suppress the noninducibility due to a GAL80(S-1)-G323R mutation, and a GAL80-M350C mutation can suppress the noninducibility due to a gal3-D111C mutation. A reverse two-hybrid selection for GAL3 mutations that impair the Gal3-Gal80 interaction yielded 12 single-amino-acid substitutions at residues that are predicted to be surface exposed on Gal3. The majority of the affected Gal3 residues localized to a composite surface that includes D111 and a sequence motif containing D368, which has been implicated in interaction with Gal80. The striking colocalization of intergenic suppressor residues and Gal80 nonbinder residues identifies a Gal3 surface that likely interacts with Gal80.

Electrical Properties of Transparent Doped Titania Films by Sol-Gel Method (SOLID STATE CHEMISTRY-Amorphous Materials) (1998)

Transparent semiconductive TiO2 films co-doped with Ru and Ta (Nb), and Co and Nb (Sb) were prepared on SiO2 glass substrates by the sol-gel method using Ti(OC3H7 i)4 solutions. The solution preparation condition, solution composition, dopant content and heat-treatment temperature all severely affected the electrical resistivity of the resultant films. TiO2 films co-doped with Ru and Ta (Nb) showed n-type conductivity, while those co-doped with Co and Nb (Sb) showed p-type conductivity. It seems that the obtained films can be utilized for assembling all-solid-state TiO2-based pn type solar cell.
Development of muscarinic-cholinergic stimulation of inositol phosphate production in cultured embryonic chick atrial cells. Evidence for a switch in guanine-nucleotide-binding protein coupling (1990)

We have demonstrated that muscarinic stimulation of inositol phosphate production in cultured atrial cells from chicks at 14 days in ovo is partially sensitive to inhibition by pertussis toxin. In these cells, muscarinic agonist binding is coupled to phospholipase C activity via at least two guanine-nucleotide-binding proteins (G-proteins), one sensitive to pertussis toxin and the other (Gp) insensitive to pertussis toxin [Barnett, Shamah, Lassegue, Griendling & Galper (1990) Biochem. J. 271, 437-442]. In the current study we demonstrate that during embryonic development of the chick heart, muscarinic stimulation of inositol phosphate production decreases by 50% between days 5 and 14 in ovo in cells cultured from both atrium and ventricle. In atrial cells, however, pertussis toxin-sensitive muscarinic stimulation of inositol phosphate production increased from undetectable levels at day 5 in ovo to 40% of total stimulation at day 12 in ovo. Muscarinic stimulation of inositol phosphate production in the ventricle did not become sensitive to pertussis toxin at any age studied. In permeabilized atrial cells from embryonic chicks at 5 days in ovo, guanosine 5'-[gamma-thio]triphosphate (GTP[S]) stimulated InsP1 levels by 40 +/- 10% (mean +/- S.E.M., n = 3), InsP2 levels by 117 +/- 18% and InsP3 levels by 51 +/- 8%, suggesting that at day 5 in ovo all of the muscarinic-stimulated inositol phosphate production was coupled to phospholipase C via Gp. H.p.l.c. analysis demonstrated that, in spite of these changes in coupling of phospholipase C to different G-proteins, no changes could be demonstrated in the isomers of InsP3 produced in response to carbamylcholine at both days 5 and 14 in ovo. These data demonstrate that embryonic development of the chick atrium is associated with a switch in coupling of muscarinic receptors to phospholipase C from Gp to a pertussis toxin substrate. This developmental switch in coupling of G-proteins may be related to possible developmental switches in levels of muscarinic receptor isoforms or switches in the subtype of phospholipase C.

<title>Multimodality cardiac image review station using dynamic decompression of JPEG images</title> (1995)

A cardiology review station for clinical use has been developed which can decompress, zoom, and display full resolution JPEG-encoded cardiac angiograms and echocardiograms in real- time (30 frames/second). The review station is installed in a network which includes a digital image archival system throughout Duke University Medical Center. The review station consists of a DEC 3000/600 AXP workstation with a DEC J300 sight and sound multimedia board. The J300 is used to decompress up to 45 true color JPEG-encoded frames/sec. at normal (512 X 512) resolution and 30 frames/sec. at 1.5 X zoom. Digitally acquired 512 X 512 X 8 bit monochrome angiograms as well as 600 X 430 X 8 bit color and monochrome echocardiograms are transferred to the workstation where they are JPEG-encoded in real time using the J300 board. A compression factor of approximately 15:1 is being used. A graphical user interface (GUI) developed using OSF/Motif 1.2 enables a clinical user to simultaneously display and control several image sequences. A sequence can be retrieved in under three seconds and displayed dynamically in forward or reverse directions with instantaneous speed control. Utilizing a commercial relational database (Sybase), the GUI organizes image sequences for a patient by image modality, location, time, and view. A schematic representation of cardiac anatomy allows a user to view specific angiographic image sequences by selecting appropriate objects in the anatomic diagram.
Nonlinear scattering of acoustic waves by vibrating obstacles (1982)

The problem of scattering of an acoustic wave (at angular frequency ω) by an obstacle whose surface vibrates harmonically (at angular frequency Ω) was studied both theoretically and experimentally. The theoretical approach involved solving the nonlinear wave equation, subject to appropriate boundary conditions, by use of a perturbation expansion of the fields and a Green's function method. This problem was previously studied theoretically by D. Censor [(J. Sound Vib. 25, 101–110 (1972)], who used the linear wave equation together with nonlinear boundary conditions to obtain his solution. In addition to ordinary rigid-body scattering, Censor predicted nongrowing waves at the sum and difference frequencies ω± = ω ± Ω. The solution to the nonlinear wave equation also yields scattered waves at frequencies ω±. However, the amplitudes of these waves tend to grow with increasing distance from the scatterer's surface and after a very small distance dominate those predicted by Censor. Preliminary experimental results are in qualitative agreement with the theoretical results based on the nonlinear wave equation.

[Improvement of the concentration method of the "head space" above wine for direct gas chromatographic analysis by means of two absorbent polymers (author's transl)]. (1976)

It has been defined, in a previous work, a procedure for the "head space" gas chromatographic analysis. This method allowed the separation of 17 volatile constituents, utilizing Porapak Q, either as trap or chromatographic adsorbent. A series of new experiences have improved this precedure, adopting as trap two polymers (Porapak Q, copolymer of the ethyl-vinyl-benzene divinyl-benzene; Tenax GC porous polymer 2,6-diphenyl-p-phenilene oxide) and two different chromatographic phases. Furthermore, it has been entirely modified the introduction of the sample into the gas chromatographic column simplifying the handling and improving the operative conditions (times and temperature of desorption). The analysis of the "head space" carried out on wines of different aromatic compositions (Riesling) and on wines at different degree of ageing (Rubesco), besides having allowed the separation of 61 volatile components, 27 of which have identified, has put in evidence the sensitivity of this procedure.

Starting from a brief analysis of classic bibliography on yellow fever, the fist studies carried out in Cuba on this condition carried out in Cuba and some important writings on this topic by Carlos J. Finlay the priority of the Cuban wise in the discovery of the mode of transmission of this condition by the Aedes aegypti mosquito and also the prevention method corroborating, at the same time, that in that sense there were not precedings. To corroborate this statement, a translation to Spanish of a letter sent by Walter Reed to Carlos J Finlay dated in October, 1900 requesting information on the experiments carried out with the insect.

Robustness to Bit Inversion in Registers and Acceleration of Program Evolution in On-Board Computer (2011)

This paper focuses on an on-board computer (OBC) that evolves computer programs through bit inversion and targets analyzing robustness against bit inversion in registers. We also propose a new method that can change the number of computer programs dynamically. Intensive experiments revealed the following: (1) Correct programs can be maintained even in bit inversion in registers in addition to bit inversion in instructions. (2) Our proposal accelerates program evolution by increasing the population size, i.e., the number of programs, within fixed memory size.

A mixture-site model for edge-preserving image restoration (2002)

The paper summarizes a new Bayesian method for edge-preserving image restoration from noisy measurements. The line-site method of Geman and Geman (1984) forces region boundaries to lie along pixel boundaries, which is unnatural, particularly for 3D data. The present authors augment the intensity process with a binary "mixture site" process, which has one parameter for each pixel indicating the presence of a boundary at some unknown location within that pixel. The method was motivated by the PET and SPECT transmission images with partial volume effects, and is easily extended to 3D data sets.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

SELECTIVE SORPTION OF D-AND L-TRYPTOPHAN BY CHITOSAN AND ITS N-ACYLATED DERIVATIVES (1986)

The chemical modification of chitosan by N-acylation of the amino groups with various carboxylic anhydrides was performed to introduce a new functionality. The equilibrium sorption of tryptophan by the N-acylated chitosan gels was determined at 30°C. The N-dodecanoyl derivative has a lower equilibrium sorption as compared with the original chitosan resulting from the more compact structure of the gel. On the other hand, the N-octadecanoyl derivative, which can not form a compact structure due to a longer side chain, has a higher sorptivity of tryptophan. The N-octadecanoyl chitosan gel having a degree of substitution of 0.45, selectively sorbs L-tryptophan from an aqueous 1:1 D, L-tryptophan solution of 1.015×10-2 mol•dm3 giving a ratio of sorption of L/D ≈60.
A neural predictor for blind equalization of digital communication systems: is it plausible? (2002)

In digital channel equalization, self-learning techniques are used in the cases where a training period is not available. Considering the transmitted sequence as composed of independent random variables, the equalization task can be done by means of prediction. In this work we propose artificial neural networks (ANN), instead of a linear prediction device, in order to obtain a better performance and analyse its performance and applicability. Linear and nonlinear prediction concepts are revisited and a new self-organized algorithm is proposed to update the first layer in the nonlinear predictor whose aim is to avoid local minimum points in the applied cost function. The second layer is updated by using a classical supervised algorithm based on prediction error. Simulation results are presented which illustrate the performance of this technique.
Effect of Test Method on SSC Performance of Modified 13Cr Steel (1998)

Abstract Effect of test method on SSC performance of modified 13Cr martensitic stainless steel (0.025C-13Cr-Ni-Mo) are investigated. The SSC for martensitic stainless steel initiates at the pitting and propagates by hydrogen embrittlement. The pH stability of the test solution affects the test results. SSC threshold stress for modified 13Cr steel in the stable solution is higher than that in the unstable solution. This difference seems to depend on the pH value in the pitting, since a great volume of hydrogen enters into steel at low pH condition and causes SSC. The SSC susceptibility for subsize specimens is higher than that for full size specimens. The oxygen in the test solution causes pitting. The deaeration procedure affects the SSC test result. The deaerated test solution should be transferred to test vessel. The SSC performance for martensitic stainless steel should be evaluated by full size test specimens under stable pH condition.
Fine needle aspiration cytology of malignant melanoma of the skin. (1981)

Fifty malignant melanomas of the skin were aspirated with a fine needle, and the cytomorphologic features of the smears were evaluated. An attempt was made to establish the frequency of morphologic features found in melanoma cells. The following features were regarded as frequent: lack of cohesiveness between the malignant cells; binucleated, multinucleated and giant cells; and intranuclear "vacuoles." The nuclei usually had a regular outline, and the nuclear chromatin was evenly distributed. The majority of the smears contained a mixture of epithelial-type and spindle cells. The nuclei of the epithelial-type cells were usually in an eccentric position. The morphologic features of malignant cells in smears, as described, can be helpful in making the preoperative cytologic diagnosis of nonpigmented malignant melanoma of the skin.
Preservation of urinary postprandial alkaline tide despite inhibition of gastric acid secretion. (1980)

Ingestion of food leads to a rise in urinary pH. This phenomenon is commonly known as "postprandial alkaline tide" and is generally attributed to acid secretion in the stomach. To examine this hypothesis, we studied the changes of urinary pH, H+ concentration, PCO2, and bicarbonate in nine healthy volunteers with and without histamine H2 receptor blockade, using cimetidine and placebo medication. Postprandial alkaline tide persisted and was even exaggerated during treatment with cimetidine. Preservation of postprandial urinary alkaline tide, despite the expected inhibition of gastric acid secretion by cimetidine, tends to exclude a causal relation between alkaline tide and gastric acid secretion.

Analysis of the distribution of pitch angles in model galactic disks - Numerical methods and algorithms (1993)

Numerical methods and algorithms are developed for analyzing the morphology of global and local structure in prototype and observed disk- shaped galaxies. One prototype spiral galaxy, taken from the 1992 theoretical-computational studies of Roberts et al., serves as the representative candidate to be analyzed in this paper. From the computed distribution of the gaseous component, "partitioning" methods based on nearest-neighbor and Voronoi polyhedra calculations are applied to capture regions of high-population gas density associated with local arm segments, spurs, feathers, and secondary features. The pitch angle and length of each of these features are determined using least-squares procedures minimizing perpendicular distances from data points to the regression curve in adapted logarithmic spiral coordinates. The resulting least-squares approximations are further checked for goodness of fit using the Kolmogorov-Smirnov test. Despite the fact that the representative prototype model galaxy is driven by an underlying global two-armed density wave of 10^deg^-15^deg^ pitch angle, the gas response is found to exhibit many local and mesoscale spiral features of much greater pitch angle. These features are attributed to the self-gravitational effects of the gas itself on local scales. Prominent peaks are found in the computed pitch angle distribution between 20^deg^ and 40^deg^; these are attributed to spurs and local arm segments that branch off the underlying 10^deg^-15^deg^ modal density-wave-driven global spiral pattern. Prominent highly inclined spurs and feathers in the outer half of the prototype galaxy are found to give rise to a peak pitch angle distribution between 50^deg^ and 55^deg^.
Optimal input design for aircraft instrumentation systematic error estimation (1991)

A new technique for designing optimal flight test inputs for accurate estimation of instrumentation systematic errors was developed and demonstrated. A simulation model of the F-18 High Angle of Attack Research Vehicle (HARV) aircraft was used to evaluate the effectiveness of the optimal input compared to input recorded during flight test. Instrumentation systematic error parameter estimates and their standard errors were compared. It was found that the optimal input design improved error parameter estimates and their accuracies for a fixed time input design. Pilot acceptability of the optimal input design was demonstrated using a six degree-of-freedom fixed base piloted simulation of the F-18 HARV. The technique described in this work provides a practical, optimal procedure for designing inputs for data compatibility experiments.

Pruning local feature correspondences using shape context (2004)

We propose a novel approach to improve the distinctiveness of local image features without significantly affecting their robustness with respect to image deformations. Local image features have proven to be successful in computer vision tasks involving partial occlusion, background noise, and various types of image deformations. However, the relatively high number of outliers that have to be rejected from the correspondences set, formed during the search for similar features, still plagues this approach. The task of rejecting outliers is usually based on estimating the global spatial transform suffered by the features in the correspondences set. This presents two problems: (i) it cannot properly deal with non-rigid objects, and (ii) it is sensitive to a high number of outliers. Here, we address these problems by combining typical local features with shape context. A performance evaluation shows that this new semi-local feature generally provides higher distinctiveness and robustness to image deformations, thus potentially increasing the inlier/outlier ratio in the correspondences set. Also, we show that in wide baseline stereo matching, and non-rigid motion applications, the use of the novel semi-local feature not only provides robustness to non-rigid deformations, but also produces a higher inlier/outlier ratio than the standard Hough clustering of the global spatial transform of parameters.
