Transparent polymer and diamond-like hydrogenated amorphous carbon thin films by PECVD technique (2008)

Optical, electrical and structural properties of hydrogenated amorphous carbon films deposited by radio frequency plasma enhanced chemical vapour deposition technique (RF-PECVED) have been investigated thoroughly. The films were deposited using a mixture of hydrogen and acetylene gases at a low substrate temperature of 200 °C. The electrical resistivities of the films are ≥ 109 Ω cm. The ratio of hydrogenated sp3 to sp2 bonded carbon atoms in the films is obtained by deconvoluting the infrared spectra over the 2800 cm−1–3100 cm−1 range. Polymer-like hydrogenated amorphous carbon films are grown at a low power (50 mW cm−2) having a high hydrogen content (30.3–46.1 at%). Increase in hydrogen dilution increases the total hydrogen content as well as the ratio of hydrogenated sp3 to sp2 carbon bonding and it becomes a maximum at an optimum hydrogen dilution. Similarly the grain density also increases with the increase in hydrogen dilution. On the other hand, at a higher RF power of 150 mW cm−2 much stronger C–C sp3 and C–C sp2 bonds are formed and the total hydrogen content drastically reduces to a very low value of 1.1–1.8 at%. This indicates the growth of hydrogenated diamond-like carbon (DLC) structure. The stronger C–C sp3 bonds present in the DLC film make the films harder as well as Raman active.

Long Term Serial Repitching and the Genetic and Phenotypic Stability of Brewer's Yeast (2007)

Two brewing yeast strains, one employed for the production of an ale type product and the other used solely for bottle conditioning, were serially repitched over a period of one year. Subsequently each yeast culture was compared to the original stocks for a variety of phenotypic and genotypic characteristics. Fermentation performance was assessed in terms of flocculation capacity and the time required to achieve attenuation in 150 barrel fermentation vessels, while the propensity for the population to accumulate variants was assessed by analysing giant colony morphology. Changes to the genome were monitored by DNA fingerprinting of each yeast culture using RAPD-PCR and RFLP. Although some colony morphology variation was observed between fresh and old ale yeast cultures, there were no detectable genetic changes or alterations in fermentation characteristics to either yeast strain over the course of serial repitching. It is suggested that although some brewing yeast strains are susceptible to genetic drift, others are more resilient and can remain stable over extended periods of time. The propensity to produce variants may therefore play a significant role in determining the number of times a strain may be serially repitched, or its suitability for beer fermentations.

<i>Agrobacterium rhizogenes</i> GALLS Protein Contains Domains for ATP Binding, Nuclear Localization, and Type IV Secretion (2006)

Agrobacterium tumefaciens and Agrobacterium rhizogenes are closely related plant pathogens that cause different diseases, crown gall and hairy root. Both diseases result from transfer, integration, and expression of plasmid-encoded bacterial genes located on the transferred DNA (T-DNA) in the plant genome. Bacterial virulence (Vir) proteins necessary for infection are also translocated into plant cells. Transfer of single-stranded DNA (ssDNA) and Vir proteins requires a type IV secretion system, a protein complex spanning the bacterial envelope. A. tumefaciens translocates the ssDNA-binding protein VirE2 into plant cells, where it binds single-stranded T-DNA and helps target it to the nucleus. Although some strains of A. rhizogenes lack VirE2, they are pathogenic and transfer T-DNA efficiently. Instead, these bacteria express the GALLS protein, which is essential for their virulence. The GALLS protein can complement an A. tumefaciens virE2 mutant for tumor formation, indicating that GALLS can substitute for VirE2. Unlike VirE2, GALLS contains ATP-binding and helicase motifs similar to those in TraA, a strand transferase involved in conjugation. Both GALLS and VirE2 contain nuclear localization sequences and a C-terminal type IV secretion signal. Here we show that mutations in any of these domains abolished the ability of GALLS to substitute for VirE2.
Investigation of a fixed‐bed pilot plant reactor by dynamic experimentation. Part 1. Apparatus and experimental results (1985)

Abstract A non‐isothermal, non‐adiabatic fixed‐bed pilot reactor specially designed for fast measurement of axial and radial temperature and concentration profiles during dynamic experiments is described. The pilot plant is interfaced to a process computer and facilitates conducting different types of dynamic experiments, such as those with simultaneous un‐correlated periodic changes of the process variables. This type of dynamic experiments proved to be most efficient for collecting the data necessary for reactor modelling. Axial and radial temperature and concentration profiles in the fixed bed were measured during catalytic hydrogenation of toluene on an industrial nickel catalyst. Peak shaped perturbations were employed to study the parametric sensitivity of the reactor behaviour and to estimate the reaction kinetics.
Phenylbutyrate inhibits the invasive properties of prostate and breast cancer cell lines in the sea urchin embryo basement membrane invasion assay (2002)

Histone deacetylase inhibitors, such as phenylbutyrate, are currently undergoing clinical trials as potential anticancer agents. Phenylbutyrate can induce cell differentiation and apoptosis in a number of cancer cell types and can act in synergy with ionizing radiation and chemotherapy to induce apoptosis. We used the sea urchin embryo basement membrane invasion assay to show that phenylbutyrate potently inhibited the invasive properties of both prostate and breast cancer cells at clinically achievable doses. This inhibition was dose-dependent and persisted for at least 24 hr after the drug was removed. These results suggest that in addition to activating apoptosis in cancer cells, phenylbutyrate may be used in prevention of metastatic disease.
Predicting Job Salaries from Text Descriptions (2013)

An online job listing web site has extensive data that is primarily unstructured text descriptions of the posted jobs. Many listings provide a salary, but as many as half do not. For those listings that do not provide a salary, it is useful to predict a salary based on the description of that job. We tested a variety of regression methods, including maximum-likelihood regression, lasso regression, artificial neural net- works and random forests. We optimized the parameters of each of these methods, validated the performance of each model using cross validation and compared the performance of these methods on a withheld test data set.
Equilibrium Relativity Humidity (ERH) Relationships for Yellow-Dent Corn (1989)

ABSTRACT Methodology for rapid collection of equilibrium relative humidity (ERH) data for grains and seeds has been developed. It is used to study the effects of variety, year grown, hysteresis and drying treatment on the ERH of yellow dent corn. Variety and year grown have a significant effect on ERH isotherms. Hysteresis occurs over almost all of the RH range although the amount of hysteresis decreases as moisture sorption temperature increases. The water adsorbing ability of yellow-dent corn decreases as the drying temperature increases. The interaction of drying treatment and rewetting significantly affects moisture sorption properties.
Chiral lanthanide complexes as probe of nucleic acids (2001)

A series of kinetically stable chiral lanthanide complexes has been developed, with a view to developing responsive probes for use in analysis and in seeking chiral complexes exhibiting selectivity in their interaction with nucleic acids. Firstly a pH sensitive complex has been modified with the aim of tuning the pH range to which it responds to the physiologically useful regime. The synthesis was undertaken of relatively lipophilic 6-butylphenanthridinyl complexes. Their photophysical behaviour was investigated by absorbance and luminescence spectroscopy and the modulation of their emission examined in the pH range 4.5 to 7.5.In addition to their luminescent properties, enantiomerically pure chiral lanthanide complexes permit chiroptical techniques to be used, allowing their interactions with other chiral species to be addressed (e.g. nucleic acids, oligonucleotides).The first series of enantiopure lanthanide complexes has been devised that show several interesting features in binding to oligonucleotides and nucleic acids. These macrocyclic tris-and tetra-amide lanthanide (Eu, Tb or Yb) complexes contain an N-alkyl phenanthridinium unit that allows intercalation between the base pairs of the DNA. Their binding to [(AT)(_6)](_2), [(CG)(_6)](_2) and CT-DNA was monitored by changes in the ligand and metal based luminescence, and in the characteristic CD bands of the oligonucleotides. Binding affinities were assessed using intrinsic methods and the McGhee-von Hippel analysis. Marked differences have been observed in the binding of Eu and Yb complexes as a function of the A and Î helicity of the complexes, which is itself determined by the configuration of the remote amide substituents. Binding of the A-Eu complex was over 50 times stronger to [(CG)(_6)](_2) compared to [(AT)(_6)](_2), while the left handed Î-Yb complex showed a different pattern of selectivity. In the europium complex of a related heptadentate tris-amide ligand, the coordination of a DNA phosphate group to the lanthanide centre was suggested by emission and lifetime changes. Another series of chiral tetraamide complexes linked to the 6 position of the phenanthridine moiety was synthesised and studied. An additional stereogenic centre at carbon, alpha to the phenanthridine group was introduced with the aim of tuning the selectivity of binding. A set of four diastereoisomeric ligands was separated and their lanthanide complexes characterised. The binding of their Eu and Yb complexes was evaluated and differences between Eu and Yb complexes persisted. The additional chiral centre did not appear to modify the binding affinity of this series of complexes. Finally, a series of 6-phenanthridinyl complexes was investigated in which the phenanthridine N atom was directly bound to the lanthanide centre. Their affinity for DNA was found to be relatively low, which may be related to their rigid structure.
Local regulation of the coronary circulation in health and disease: role of nitric oxide and endothelin (1995)

Coronary artery disease is the leading cause of morbidity and mortality in western countries. Its pathogenesis is unknown, but involves enhanced vasoconstriction, increased interaction of platelets and monocytes with the vessel wall, as well as proliferation, migration and extracellular matrix formation of vascular smooth muscle. The endothelium lies in a strategic anatomical position between circulating blood and vascular smooth muscle cells. This supports the concept that dysfunction of these cells significantly contributes to coronary artery disease. Besides other mediators, endothelial cells are a source of nitric oxide and endothelin. Nitric oxide is a vasodilator, an inhibitor of both platelet function and proliferation and migration of vascular smooth muscle. Endothelin is a potent vasoconstrictor that facilitates proliferation. Under pathological conditions, in particular the presence of cardiovascular risk factors, endothelial dysfunction occurs and is a major contributor to the increase in platelet vessel wall interaction, vasoconstriction and proliferation in the coronary system. Endothelium-dependent vasodilation is usually reduced and endothelium-dependent constrictor responses, as well as endothelin production, are augmented. Hence, endothelial cells are important targets and mediators of coronary artery disease.
Blood flow measurements at different depths using photoplethysmography and laser Doppler techniques (2009)

The study showed that the new system is satisfactory for measuring tissue blood flow at different depths. The laser Doppler complements the photoplethysmography, and further development of the system into a thin flexible probe with the ability to measure a larger area is required.
A novel high-speed quasi-SOI power MOSFET with suppressed parasitic bipolar effect fabricated by reversed silicon wafer direct bonding (2002)

One of the most important issues related to thin-film SOI power MOSFETs is how to improve their high-frequency switching performance. Reducing the product of on-resistance (Ron) and output capacitance (Coss) by shrinking the design rule is an effective way to improve it. However, it has a limitation because it pronounces the parasitic bipolar effect which degrades the high-frequency performance and shrinks the safety operating area. Forming body contacts is a useful way to suppress the parasitic bipolar effect, however it increases Ron/spl middot/Coss. A quasi-SOI structure was proposed to overcome the problem of the parasitic bipolar effect based the numerical simulations. This paper presents a novel high-speed quasi-SOI power MOSFET and its fabrication process.

Classical wave propagation in periodic structures (1989)

We considered a muffin-tin periodic potential (-\ensuremath{\delta} inside the spheres and zero outside). Using the augmented-plane-wave method we studied systematically the location of gaps for positive energy and for various values of \ensuremath{\delta} and the sphere radius a. Our results are applicable to the problem of classical wave propagation in composite media and relevant to the problem of optical localization.
Conducting Polymers for Neutron Detection (2007)

Conjugated polymers have emerged as an attractive technology for large-area electronic applications. As organic semiconductors, they can be used to make large-area arrays of diodes or transistors using fabrication techniques developed for polymer coatings, such as spraying and screen-printing. We have demonstrated both neutron and alpha detection using diodes made from conjugated polymers and have done preliminary work to integrate a boron carbide layer into the conventional polymer device structure to capture thermal neutrons. The polymer devices appear to be insensitive to gamma rays, due to their small physical thickness and low atomic number.
Association-based recommendation of Web information (2003)

Introduces an approach to recommendation of Web pages based on conceptual association. This approach can produce recommendatory Web page links for users based on the information that associates strongly with user's query, increase the chance to find more relevant links, and therefore improve the recall of a search engine. We discuss the meaning, effect and variety of conceptual association, and describe how to generate associational information related with a user's query and how to realize the association-based recommendation of Web pages. We also present our experimental result and give idea about our further work.
MICROBIAL METABOLISM OF AROMATIC COMPOUNDS I (1964)

Tabak, Henry H. (Robert A. Taft Sanitary Engineering Center, Cincinnati, Ohio), Cecil W. Chambers, and Paul W. Kabler. Microbial metabolism of aromatic carbon compounds. I. Decomposition of phenolic compounds and aromatic hydrocarbons by phenol-adapted bacteria. J. Bacteriol. 87:910-919. 1964.-Bacteria from soil and related environments were selected or adapted to metabolize phenol, hydroxy phenols, nitrophenols, chlorophenols, methylphenols, alkylphenols, and arylphenols when cultured in mineral salts media with the specific substrate as the sole source of carbon. A phenol-adapted culture (substrate-induced enzyme synthesis proven) was challenged in respirometric tests with 104 related compounds; probable significant oxidative activity occurred with 65. Dihydric phenols were generally oxidized; trihydric phenols were not. Cresols and dimethylphenols were oxidized; adding a chloro group increased resistance. Benzoic and hydroxybenzoic acids were oxidized; sulfonated, methoxylated, nitro, and chlorobenzoic acids were not; m-toluic acid was utilized but not the o- and p-isomers. Benzaldehyde and p-hydroxybenzaldehyde were oxidized. In general, nitro- and chloro-substituted compounds and the benzenes were difficult to oxidize.
Photoluminescence from laser assisted debonded epitaxial GaN and ZnO films (1999)

Photoluminescence from epitaxial GaN and ZnO films is employed as a diagnostic of the laser assisted debonding process used to separate the films from their sapphire substrates. The observed shifts in the photoluminescence spectra, recorded after separation, at 77 K are consistent with the removal of the thermal expansion mismatch strain associated with the films being cooled from their deposition temperature and indicate that after separation the films are essentially stress free.
A formal model of program dependences and its implications for software testing, debugging, and maintenance (1990)

A formal, general model of program dependences is presented and used to evaluate several dependence-based software testing, debugging, and maintenance techniques. Two generalizations of control and data flow dependence, called weak and strong syntactic dependence, are introduced and related to a concept called semantic dependence. Semantic dependence models the ability of a program statement to affect the execution behavior of other statements. It is shown that weak syntactic dependence is a necessary but not sufficient condition for semantic dependence and that strong syntactic dependence is necessary but not sufficient condition for a restricted form of semantic dependence that is finitely demonstrated. These results are used to support some proposed uses of program dependences, to controvert others, and to suggest new uses.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Static and Dynamic Big Data Partitioning on Apache Spark (2016)

Many of today's large datasets are organized as a graph. Due to their size it is often infeasible to process these graphs using a single machine. Therefore, many software frameworks and tools have been proposed to process graph on top of distributed infrastructures. This software is often bundled with generic data decomposition strategies that are not optimised for specific algorithms. In this paper we study how a specific data partitioning strategy affects the performances of graph algorithms executing on Apache Spark. To this end, we implemented different graph algorithms and we compared their performances using a naive partitioning solution against more elaborate strategies, both static and dynamic.
A Recombinant Carboxy-Terminal Domain of the Protective Antigen of <i>Bacillus anthracis</i> Protects Mice against Anthrax Infection (2002)

The immunogenicity and protective efficacy of overlapping regions of the protective antigen (PA) polypeptide, cloned and expressed as glutathione S-transferase fusion proteins, have been assessed. Results show that protection can be attributed to individual domains and imply that it is domain 4 which contains the dominant protective epitopes of PA.
Indwelling catheter infection. (1973)

A "catheter team", consisting of two hospital assistants specially trained to catheterize male patients, inserted indwelling catheters in 435 men over a two-year period. The infection rate was 33%; in the 200 patients not treated with antimicrobial drugs (study group) the rate was 37%, while in the 235 patients who were so treated (antibacterial group) the infection rate was 29%. Fifty percent of patients not treated were infected after 6.3 days, whereas in patients on antibacterial therapy a 50% infection rate was not reached until 14 days after insertion. Therefore, no antibacterial therapy is necessary if it is anticipated that the catheter will be necessary for less than four days. On the other hand, prophylactic antibacterial therapy would delay the onset of infection considerably if catheterization were expected to continue for more than four days. Sulfisoxazole was our drug of choice for prophylactic treatment.
