Real-number codes for fault-tolerant matrix operations on processor arrays (1990)

A generalization of existing real numer codes is proposed. It is proven that linearity is a necessary and sufficient condition for codes used for fault-tolerant matrix operations such as matrix addition, multiplication, transposition, and LU decomposition. It is also proven that for every linear code defined over a finite field, there exists a corresponding linear real-number code with similar error detecting capabilities. Encoding schemes are given for some of the example codes which fall under the general set of real-number codes. With the help of experiments, a rule is derived for the selection of a particular code for a given application. The performance overhead of fault tolerance schemes using the generalized encoding schemes is shown to be very low, and this is substantiated through simulation experiments.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Homing in on the Role of Transition Metals in the HNH Motif of Colicin Endonucleases (1999)

The cytotoxic domain of the bacteriocin colicin E9 (the E9 DNase) is a nonspecific endonuclease that must traverse two membranes to reach its cellular target, bacterial DNA. Recent structural studies revealed that the active site of colicin DNases encompasses the HNH motif found in homing endonucleases, and bound within this motif a single transition metal ion (either Zn(2+) or Ni(2+)) the role of which is unknown. In the present work we find that neither Zn(2+) nor Ni(2+) is required for DNase activity, which instead requires Mg(2+) ions, but binding transition metals to the E9 DNase causes subtle changes to both secondary and tertiary structure. Spectroscopic, proteolytic, and calorimetric data show that, accompanying the binding of 1 eq of Zn(2+), Ni(2+), or Co(2+), the thermodynamic stability of the domain increased substantially, and that the equilibrium dissociation constant for Zn(2+) was less than or equal to nanomolar, while that for Co(2+) and Ni (2+) was micromolar. Our data demonstrate that the transition metal is not essential for colicin DNase activity but rather serves a structural role. We speculate that the HNH motif has been adapted for use by endonuclease colicins because of its involvement in DNA recognition and because removal of the bound metal ion destabilizes the DNase domain, a likely prerequisite for its translocation across bacterial membranes.
XPL, a Presentation Language based on User Interface Design Pattern (2007)

The great diversity of presentations in software applications deals with fulfillment of various type of graphic interface constructions related to different programming languages. Moreover, in the Internet era html pages play a main role because of the increasing complexity of Web applications. In Software Engineering, the use of design patterns is proven remarkable for the design and reuse of software components. Visual design patterns (ViDP) are useful to define interaction schemas between user and computer. By the some token, visual design patterns are useful to incorporate common interfaces of interaction schemas between user and computer. This paper describes the extensible presentation language (XPL), a presentation language based on visual pattern. XPL framework implementation will be discussed in details and a case study showing the benefits of employing XPL will be presented.
Interfacial and colloidal properties of cosmetic emulsions containing fatty alcohol and fatty alcohol polyglycol ethers (2007)

The phase behavior of multicomponent systems, especially of emulsions containing cetostearyl alcohol and fatty alcohol polyglycol ethers has been investigated. At the phase inversion from o/w to w/o emulsions, one-phase regions containing lamellar liquid crystals have been observed. In appropriate ratios of the amphiphiles, extremely low interfacial tensions (≈10−3 mN/m) are obtained, which lead to very easy emulsification and narrow particle size distribution. Thermoanalysis (DSC) and microscopy of binary, ternary and quaternary mixtures demonstrate the existence of hydrated crystals or gels at room temperature. Anisotropie phases could be identified around oil droplets of more coarse emulsions. Emulsions prepared at low temperatures possess structural viscosity. Increasing the temperature leads to newtonian behavior. At medium emulsifier concentrations fluid and stable emulsions are obtained. There is a strong dependence of the properties of the emulsions on the polarity of the oil phase. It can be concluded that the ability to form fine droplets, the viscosity and the long term stability of cosmetic emulsions do not depend on the properties of the fatty alcohol alone but on the mixed phases formed by the emulsifier and the alcohol.
The Pyrolytic Behavior of Selected Lignin Preparations (1985)

Abstract A pyrolytic study of a variety of lignins prepared from hardwood and softwood species, and of selected commercial lignins, was performed using isothermal and dynamic thermogravimetric analysis and pyrolysis-gas chromatography. The lignins were evaluated according to weight loss, rate of weight loss, and products formed during the pyrolysis in an inert atmosphere. These data were then compared to nitrobenzene oxidation data. Infrared spectroscopy was used to determine structural changes of lignin during initial weight loss in the temperature range of 250° to 320°C. Structural changes appear to occur without any appreciable weight loss. Lignin's thermal behavior during pyrolysis depends upon the degree of condensation present in the initial lignin. Thermogravimetric analysis is shown to be a simple and accurate method to determine the extent of lignin condensation. The yield of monomeric phenols is also dependent on the degree of lignin condensation.
Photochemically induced reaction between perfluoroacetone and ethane (1975)

Abstract The gas‐phase photolysis of perfluoroacetone in the presence of ethane has been shown to result in the production of significant amounts of 1, 1‐bis(trifluoromethyl)propanol‐1, (CF 3 ) 2 (C 2 H 5 )COH, and 1, 1, 4, 4‐tetrakis(trifluoromethyl)butane‐1, 4‐diol, (CF 3 ) 2 C(OH)‐CH 2 CH 2 C(OH)(CF 3 ) 2 . A mechanism is presented which accounts for the relative rates of formation of these products at room temperature.
Triamcinolone Injections In Herpes Zoster Lesions (1969)

To the Editor:— In today's scientifically oriented medical world, new therapeutic maneuvers are not accepted without statistically significant series supported by valid controls. Yet, there are some instances in which the success of the therapy and the seriousness of the condition as measured by morbidity, disability, and even death make it mandatory that knowledge about a promising approach be brought to the attention of the practicing physician prior to the time that all scientific challenges can be met and conquered. Herpes zoster is such a disease. While the condition is capricious in its response to treatment, postzoster neuralgia tends to be constant and therapeutically resistant. Feeling that it would be unwise to maintain silence in this matter, the following therapeutic suggestion is being made. Its value, or lack thereof, can be established only by usage in many patients by multiple practitioners. However, in my hands, this has superseded all other
Design of a resonant micro reciprocating engine for power generation (2004)

Structure and performance of a silicon based micro reciprocating engine have been designed. The Otto cycle with hydrogen fuel has been adopted for the working cycle. The micro reciprocating engine is composed of opposite-pistons supported by an elastic spring. Resonant mode of the elastic spring is excited due to combustion pressure to increase the generated electric power. Theoretical electric power was found to be /spl sim/40 mW under the conditions that the compression ratio is 5, the maximum combustion temperature is 850 K and the first resonant frequency of the elastic spring is 610 Hz. The micro engine can be expected to use as a portable micro power generator with high energy density.
Indoleamine 2,3-dioxygenase-1 (IDO1) expression by childhood acute myeloid leukemias inhibits T-cell production of IFN-γ and confers an unfavorable prognosis (2013)

Meeting abstracts Indoleamine 2,3-dioxygenase 1 (IDO1) degrades tryptophan into kynurenine (KYN) and other immune suppressive molecules that inhibit effector T cells and promote regulatory T-cell differentiation. We have previously shown that IDO1 mRNA and protein are detectable in blast cells from
Scattering by randomly oriented ellipsoids: Application to aerosol and cloud problems (1979)

A program was developed for computing the scattering and absorption by arbitrarily oriented and randomly oriented prolate and oblate spheroids. This permits examination of the effect of particle shape for cases ranging from needles through spheres to platelets. Applications of this capability to aerosol and cloud problems are discussed. Initial results suggest that the effect of nonspherical particle shape on transfer of radiation through aerosol layers and cirrus clouds, as required for many climate studies, can be readily accounted for by defining an appropriate effective spherical particle radius.
The supremum distribution of a Lévy process with no negative jumps (1977)

Let be a process with stationary, independent increments and no negative jumps. Let be this same process modified by a reflecting barrier at zero (a storage process). Assuming that – and denote by ψ( s ) the exponent function of X. A simple formula is derived for the Laplace transform of as a function of W (0). Using the fact that the distribution of M is the unique stationary distribution of the Markov process W , this yields an elementary proof that the Laplace transform of M is µ s /ψ( s ). If it follows that These surprisingly simple formulas were originally obtained by Zolotarev using analytical methods.

Cultuurdeelname in de levensloop (2004)

The general question of this study is: how does the participation in cultural activities develop during the first 35 years of the life course, in consequence of the family of origin and later acquired social status? \n\nTaking the results based on cross-sectional data as a starting point, this study analyzes mainly longitudinal (life-history) data referring to 1028 Dutch former schoolmates graduated from 31 secondary schools. The data also contain extensive and independent information on cultural activities in the parental home, obtained by interviewing 840 parents. In addition, for 654 respondents the siblings nearest in age were located and information was collected on their cultural participation. The combined clustering of former schoolmates within schools, and siblings within families, made it possible to estimate total effects of family and school.\n\nIn sum, the main findings are:\n* Cultural participation emerges as a rather stable kind of behavior, originating early in life, most often in the parental family. \n* Among those who have started their cultural careers before the age of eighteen, the age of initial attendance turns out to be most effective. A person s starting age matters more to cultural participation in early adulthood than the company of the first visit, the cultural behavior by the parents or art education at school. \n* The association between the cultural behavior by parents and their offspring is at its maximum when the children are between ten and twelve years old. After the age of ten (museum) or twelve (stage arts) the resemblance in cultural participation between parents and children decreases, but remains positive. \n* As a result of the longitudinal research design and the opportunity to estimate total family and school effects, is has become clear that a number of apparent effects of social conditions occurring later in life are to a large extent the result of selection mechanisms. Differences in cultural participation according to later acquired status characteristics are largely present before these conditions turn up.\n* The additional influence of social conditions, occurring later in life, especially level of education and arts instruction, is found to be smaller than in studies using cross-sectional data.

A Real-Time Augmented Reality System to See-Through Cars (2016)

One of the most hazardous driving scenario is the overtaking of a slower vehicle, indeed, in this case the front vehicle (being overtaken) can occlude an important part of the field of view of the rear vehicle's driver. This lack of visibility is the most probable cause of accidents in this context. Recent research works tend to prove that augmented reality applied to assisted driving can significantly reduce the risk of accidents. In this paper, we present a real-time marker-less system to see through cars. For this purpose, two cars are equipped with cameras and an appropriate wireless communication system. The stereo vision system mounted on the front car allows to create a sparse 3D map of the environment where the rear car can be localized. Using this inter-car pose estimation, a synthetic image is generated to overcome the occlusion and to create a seamless see-through effect which preserves the structure of the scene.
Efficient implementation of lazy suffix trees (2003)

Abstract We present an efficient implementation of a write‐only top‐down construction for suffix trees. Our implementation is based on a new, space‐efficient representation of suffix trees that requires only 12 bytes per input character in the worst case, and 8.5 bytes per input character on average for a collection of files of different type. We show how to efficiently implement the lazy evaluation of suffix trees such that a subtree is evaluated only when it is traversed for the first time. Our experiments show that for the problem of searching many exact patterns in a fixed input string, the lazy top‐down construction is often faster and more space efficient than other methods.

Sialic Acid and Structural Analogues: Stereoselective Syntheses (2007)

Sialic acid (N-acetylneuraminic acid) is a carbohydrate that is often found on the ends of oligosaccharide chains in biological systems. As such, it is important in several biological recognition/communication events mediated by sialic acid recognising proteins that play integral roles in these phenomena. It is therefore necessary to develop synthetic routes to sialic acid and its derivatives and analogues. Many of these routes have led to compounds used as enzyme inhibitors for treatment of disease states and also as probes of biologically relevant binding events and of the mechanisms of enzyme action. Every position on the nine-carbon backbone of sialic acid has been derivatised for such purposes, being synthesised both chemoenzymatically and chemically from precursors ranging from non-carbohydrate sources to sialic acid itself. This review describes various synthetic strategies developed for the synthesis of sialic acid and its variants at each position on the carbon skeleton.
Surface Modification of Cold Working Die Steel, SKD 11, using Laser Irradiation. (1999)

At present, cold working die steel, SKD11, is commonly being used as a material for metal molds due to its superior wear and corrosion resistance properties. However, it is difficult to obtain die steel SKD11 with a mirror-finished surface during metal mold manufacturing, because of the coarse-grained carbides present in the base metal. In this study, laser surface modification with melting has been proposed to improve the surface finish of SKD11 as a new surface modification method. In this method, coarse-grained carbides can be decomposed by melting the surface layer using a laser beam. As a result, the carbides containing coarse grains in the surface layer can be completely decomposed into their elements by laser beam irradiation to the surface. Both the compositions and crystalline structure in the modified region are entirely uniform, and the laser irradiated material could be polished easily to obtain a mirror-finished surface using alumina as an abrasive. Moreover, the reflectivity of light from the laser irradiated surface after polishing is 15% higher than that from the surface of the as-received sample.
Kinetics of hemolysis induced by a toxin from Bacillus thuringiensis israelensis (1988)

The kinetics of hemolysis resulting from the action on rabbit erythrocytes of a highly purified cytolytic toxin (26,000 mol. wt) isolated from a spore-crystal mixture of Bacillus thuringiensis israelensis was studied. Course of hemolysis, as determined by release of hemoglobin, yielded sigmoid curves whose maximum slopes were taken as a measure of the rate of lysis. Hemolysis occurred without an induction period, and the rate of lysis was a linear function of toxin concentration. Rate of hemolysis as a function of temperature yielded an Arrhenius constant of 9300 calories per mole. The toxin was active between pH 4.5 and 8.0. Lysis was strongly inhibited by Cu2+, Fe2+ and Zn2+ in concentrations as low as 0.025 M. Phosphatidylserine, phosphatidylinositol, phosphatidylcholine and sphingomyelin inhibited lysis, whereas phosphatidylethanolamine, cerebroside, cholesterol and major integral erythrocyte membrane proteins caused little or no inhibition. Inhibition of lysis by sucrose indicates that hemolysis is of the colloid-osmotic type.
cdc25 cell cycle-activating phosphatases and c-myc expression in human non-Hodgkin's lymphomas. (1998)

cdc25A, cdc25B, and cdc25C are a family of human phosphatases that activate the cyclin-dependent kinases at different points of the cell cycle. cdc25A and cdc25B have been shown to have oncogenic potential, and they have been identified as transcriptional targets of c-myc. To determine the role of cdc25 genes in the pathogenesis of human lymphomas and their possible correlation with c-myc deregulation, we have analyzed the expression of cdc25A, cdc25B, and cdc25C and c-myc genes in a series of 63 non-Hodgkin's lymphomas and 8 nonneoplastic lymphoid tissues. The mRNA levels of the three phosphatases in the nonneoplastic tissues were negative or negligible. cdc25B overexpression was detected in 35 tumors (56%). This overexpression was more frequently found in aggressive (81%) than in indolent lymphomas (36%; P < 0.01). cdc25B overexpression was also significantly associated with a higher proliferative activity of the tumors. No cdc25B gene amplification or rearrangements were detected by Southern blot analysis. A biallelic EcoRI polymorphism of cdc25B gene was identified with a similar distribution in patients with lymphoma and in a normal population. cdc25A was overexpressed in three aggressive lymphomas. No detectable cdc25C mRNA levels were seen in any of the tumors. c-myc was overexpressed in 43% of tumors, and it correlated significantly with the presence of cdc25B up-regulation. Twenty-six of 35 (74%) lymphomas with high levels of cdc25B mRNA also showed c-myc overexpression, whereas 27 of 28 (96%) tumors without detectable or with very low cdc25B expression also had undetectable c-myc levels (P < 0.0001). In addition, a significant linear correlation was found between the cdc25B and c-myc mRNA levels (r = 0.575, P < 0.001). These findings suggest that cdc25B overexpression in non-Hodkin's lymphoma may participate in the pathogenesis of aggressive variants, and it may cooperate with c-myc oncogene in the development of these tumors.
