Investigation of rotated X-cut Ca3TaGa3Si2O14 single crystals operating in FS mode in the temperature range up to 900°C (2014)

Crystal elements manufactured made of calcium tantalum gallium silicate single crystals (CTGS) operating in face shear mode were investigated. The frequency temperature characteristics of the rotated X-cut in high temperature range (up to 900°) were measured. The largest coupling factor close to 21.1% was found for (XYt) 9°-cut. It was shown that frequency temperature characteristic has a departure from a quadratic parabola which is atypical for langasite family crystals. The maximum value of the turnover temperature point 578° corresponds to (XYt) 9°-cut.
Characterization of RNA and DNA synthesis in Escherichia coli strains devoid of ppGpp (1993)

The synthesis rates of DNA, rRNA, bulk mRNA, protein, and RNA polymerase beta- and beta'-subunits were determined as functions of growth rate in a wild-type Escherichia coli strain, which produces guanosine tetraphosphate (ppGpp), and in a delta relA delta spoT mutant which does not produce ppGpp. The rate of stable RNA synthesis per amount of protein depends on three factors: RNA polymerase concentration, RNA polymerase activity, and the distribution of active RNA polymerase between stable and mRNA genes, measured as the stable RNA synthesis rate/total RNA synthesis rate, rs/rt. In the wild-type strain, all three factors increase with growth rate. In the ppGpp-deficient strains, only RNA polymerase synthesis and activity, but not rs/rt, increased with growth rate. Thus, adjustments of rs/rt require ppGpp. In the absence of ppGpp, the synthesis of rRNA and bulk mRNA both varied in direct proportion to the concentration of active RNA polymerase, in contrast to the wild-type strain, in which only rRNA synthesis increased with growth rate, while mRNA synthesis remained constant. Thus, a control specific for rRNA is absent in strains lacking ppGpp. In rich media, the ppGpp-deficient strain synthesized up to 4-fold more mRNA than wild-type bacteria, which was associated with a similarly increased RNA polymerase activity. We propose that RNA polymerase is rendered inactive in wild-type bacteria due to ppGpp-dependent transcriptional pausing during the synthesis of mRNA. Finally, the control of replication initiation was altered in ppGpp-less bacteria, apparently reflecting indirect changes in the cell physiology, rather than a direct effect of ppGpp on replication initiation.
P-HEMTs for low-voltage portable applications using filled gate fabrication process (2002)

A fundamental change in gate formation to a filled gate process was combined with changes in film deposition. The resulting p-HEMT manufacturing process gives much better performance for low-voltage RF amplification. At a drain voltage of 3.5 V, a 12-mm periphery device fabricated by this method is capable of 33 dBm output power with an associated power-added efficiency of greater than 75%.

Expression feature extraction based on difference of Local Binary Pattern histogram sequences (2008)

In this work, we present a novel facial feature extraction method for automatic facial expression recognition, which is based on difference of local binary pattern histogram sequences. First, the Local Binary Pattern (LBP) technique is used to extract facial texture features. Then the LBP Map is divided into non-overlapping rectangle regions with specific size, and histogram is computed for each region, which is concatenate to form histogram sequence called LBPHS. At last, the difference between the LBPHSes (DLBPHS) of the expression image and the neutral expression image is computed to form the final facial expression feature. The proposed feature extraction algorithm is tested on the JAFFE database and experimental results show that it is promising.

Diode-pumped passively mode-locked Yb:YLF laser (2008)

We demonstrate passive mode-locking by means of a semiconductor saturable-absorber mirror in a diode-pumped Yb:YLF laser. We present crystal growth process, spectroscopic measurements, and investigation of mode-locking performance. Pulse trains with minimum duration of 196 fs, average power of 54 mW and a repetition rate of 55 MHz were obtained. The optical spectrum, centered at 1028 nm, has a 7.1-nm bandwidth leading to nearly transform-limited pulses.
What Are the Implications of Rising Commodity Prices for Inflation and Monetary Policy (2011)

The recent run-ups in oil and other commodity prices and their implications for inflation and monetary policy have grabbed the attention of many commentators in the media. Clearly, higher prices of food and energy end up in the broadest measures of consumer price inflation, such as the Consumer Price Index. Since the mid-1980s, however, sharp increases and decreases in commodity prices have had little, if any, impact on core inflation, the measure that excludes food and energy prices.
Use of Dispersants/Detergents in Diesel Injector Keep Clean and Clean Up Studies (1991)

<div class="htmlview paragraph">Considerable work has gone into the development of an active diesel injector additive with both deposit keep clean and clean up capabilities. TFA-4681, a high molecular weight polyisobutylene (PIB) derivative with amine functionality, was developed. In testing done with a GM 6.2 liter engine, a Daimler Benz OM-616 engine, and in testing using two 1981 Mercedes Benz 240D vehicles, the effectiveness of this additive was established.</div> <div class="htmlview paragraph">Some principals of surfactant theory as they relate to this additive development are discussed. The additive behaves as a surfactant in hydrocarbon medium. According to theory, an additve can act as a detergent (keep clean) by adsorption on a metal surface and, also, as a dispersant (clean up) by forming micelles with deposits. Usually, only high molecular additives are capable of behaving as detergent/dispersants with both keep clean and clean up activity.</div> <div class="htmlview paragraph">Experimental work on additive T-96A indicated that neither its clean up nor its keep clean activity increases linearly with concentration but levels off at some intermediate additive concentration. This is discussed in terms of a monolayer adsorption of the additive on the injector or deposit surface.</div> <div class="htmlview paragraph">Based upon infrared studies, the deposit surface contains considerable oxidation products such as carboxylic acid, anhydrides, etc. In a first step, the amine function of the additive is thought to react with the acid moities on the injector deposit surface at monolayer levels. In a second step, the additive-deposit compound is believed to be washed off the injector surface by fresh fuel. This explains the absence of additive chemistries on the surface of injector deposits after contact with additized fuel, as indicated by infrared and X-Ray Surface Analysis (XPS) studies.</div>
A one‐hybrid system for detecting RNA–protein interactions (1996)

We have demonstrated that N protein can cause antitermination through a heterologous RNA-protein interaction and that the system is capable of detecting RNA-protein interactions of differing affinities. This approach may also be useful in screening libraries for proteins that bind to novel RNA regulatory elements. Our results are also consistent with a model of N protein function in which binding to the nascent transcript increases the effective concentration of N in the vicinity of RNA polymerase leading to antitermination.

Multimerization of Hsp42p, a Novel Heat Shock Protein of Saccharomyces cerevisiae, Is Dependent on a Conserved Carboxyl-terminal Sequence (1996)

Rap1p is a transcriptional regulator of Saccharomyces cerevisiae, which plays roles in both transcriptional activation and silencing. To identify proteins involved in Rap1p-dependent regulation of transcription, we used the two-hybrid system to screen for Rap1p-interacting proteins. Two of the clones isolated from this screen encode a truncated protein with homology to small heat shock proteins (HSPs). Here we present an analysis of this novel S. cerevisiae HSP, which we name Hsp42p. Expression of HSP42 is regulated by a range of stress conditions similar to S. cerevisiae HSP26, with which Hsp42p shares most homology. However, HSP42 expression is more sensitive to increased salt concentration and to starvation and, in contrast to HSP26 is expressed in unstressed cells. Hsp42p interacts with itself in the two-hybrid assay. This interaction is dependent on a hydrophobic region which is conserved among small HSPs. Using bacterially expressed Hsp42p fusion proteins. we demonstrate that this is a direct interaction. Fractionation of yeast protein extracts by size demonstrates that all of the Hsp42p in these extracts is present in complexes with a molecular mass of greater than 200 kDa, suggesting that Hsp42p exists in high molecular mass complexes.
Progress in the ASML EUV program (2004)

ASML has continued to make significant investments in the development of extreme ultraviolet lithography (EUVL), addressing the critical challenges, including defect-free mask handling, reflective optics technology, environmental control, and source. We present updates in these key areas and in the realization of our process development exposure tool. This tool is used to minimize the risk of EUVL for the 45-nm technology node and below, and to support the development of the global infrastructure of masks, sources, and resist. Realization of the process development tool is well underway; most of the modules are in vacuum qualification and functional testing. From arial image simulations, we conclude that EUVL tools are particularly suited for contact printing, due to the use of dark-field masks, and hence, limited influence of flare.
Tumor necrosis factor induces tissue factor-like activity in human leukemia cell line U937 and peripheral blood monocytes (1988)

The induction of procoagulant activity (PCA) by human recombinant tumor necrosis factor (rTNF) was studied in human monoblastic leukemia cell line U937 and human peripheral blood monocytes. Using a one-step recalcificating clotting assay, PCA in cell lysates or whole cell preparations was measured by comparison to a rabbit brain thromboplastin standard. There was a dose- and time-dependent increase in PCA when U937 cells were cultured with rTNF. The effect of rTNF was not enhanced by recombinant human interferon-gamma (rIFN gamma). Cycloheximide inhibited the expression of PCA by U937 cells, showing that protein synthesis was necessary to mediate the effects of rTNF. Whole cell preparations demonstrated that greater than 80% of the PCA was expressed on the surface of the cells. The PCA functioned as a tissue factor-like substance, since it required coagulation factor VII and factor X. rTNF also increased PCA in human monocytes in a dose- and time-dependent manner. This effect was abrogated by boiling the rTNF for ten minutes, and was not inhibited by adding polymyxin-B to the cultures, making it unlikely that endotoxin accounted for the observed effects. These results suggest that TNF-induced expression of tissue factor by mononuclear phagocytes may modulate immunologic, inflammatory, and hemostatic processes.
Multiple functions of Na/K-ATPase in dopamine-induced salivation of the Blacklegged tick, Ixodes scapularis (2016)

Control of salivary secretion in ticks involves autocrine dopamine activating two dopamine receptors: D1 and Invertebrate-specific D1-like dopamine receptors. In this study, we investigated Na/K-ATPase as an important component of the secretory process. Immunoreactivity for Na/K-ATPase revealed basal infolding of lamellate cells in type-I, abluminal interstitial (epithelial) cells in type-II, and labyrinth-like infolding structures opening towards the lumen in type-III acini. Ouabain (10 μmol l(-1)), a specific inhibitor of Na/K-ATPase, abolished dopamine-induced salivary secretion by suppressing fluid transport in type III acini. At 1 μmol l(-1), ouabain, the secreted saliva was hyperosmotic. This suggests that ouabain also inhibits an ion resorptive function of Na/K-ATPase in the type I acini. Dopamine/ouabain were not involved in activation of protein secretion, while dopamine-induced saliva contained constitutively basal level of protein. We hypothesize that the dopamine-dependent primary saliva formation, mediated by Na/K-ATPase in type III and type II acini, is followed by a dopamine-independent resorptive function of Na/K-ATPase in type I acini located in the proximal end of the salivary duct.

Resonant tunneling through metal (Ag–Ti)/insulator (MgO) triple barrier structures (2002)

Resonant tunneling through metal (Ag–Ti)/insulator (MgO) triple barrier structures has been demonstrated. The multilayers with the triple barrier structures were epitaxially grown on MgO (001) substrates under 473 K by the electron beam evaporation method. For the measurement of current–voltage characteristics, the mesa-isolated diodes were fabricated by photolithography. The observed current peaks in the current–voltage characteristics of the diodes could be explained as the resonant tunneling current.
Reliability of conformance tests (2001)

Conformance testing is considered from a statistical point of view. An s-confidence interval is found for the reliability that an implementation of a software package complies with specifications of a standard. Determination of whether it complies depends on a conformance test, which is written directly from the standard. Although the conformance test is written directly from the standard it does not test all possible software parameter-settings that invoke the standard. Thus, statistical inference is necessary. A general s-confidence interval for the reliability is given when the specification requires that the implementation passes all the tests in the conformance test suite. The conformance test is made of disjoint homogeneous partitions. The failure probability of the software is based on a weighted linear combination of the partition failure probabilities. An example is included.
In vivo evaluation of recombinant Vaccinia virus MVA delivering ancestral H9 hemagglutinin antigen of Avian Influenza virus (2015)

Avian Influenza (AI) viruses pose a threat to human and animal health and are responsible for potential economic losses. From the waterfowl reservoir, these RNA viruses can be transmitted to domestic poultry and humans, causing illness and death among people as well as mass culling of farm birds worldwide. This study contributes to increasing the knowledge by evaluating a promising poxvirus-based vector vaccine that carries and expresses an artificial, computationally derived hemagglutinin sequence in order to induce immunity against low pathogenic avian influenza H9N2. Modified Vaccinia virus Ankara (MVA) based vaccines have been tested in multiple human and animal trials and proved to be a safe and reliable vector system. The ancestral strategy uses a hemagglutinin sequence located at the node of a phylogenetic tree which arranges virus strains according to their evolutionary relationship. Inactivated whole virus vaccines engineered this way have conferred cross-clade protection in the ferret model of influenza A virus infections. In the present study, we aimed at testing the ancestral H9N2 MVA vaccine in the chicken model. Hereby, we tried to find answers to the following questions: What levels of H9 specific antibody responses are induced in chicken? Do the antibodies elicited by the ancestral H9 antigen cross-react with H9 antigens from other virus strains? Do the induced antibodies confer protection?
<i>PIF</i>- and <i>Pong</i>-Like Transposable Elements: Distribution, Evolution and Relationship With <i>Tourist</i>-Like Miniature Inverted-Repeat Transposable Elements (2004)

Abstract Miniature inverted-repeat transposable elements (MITEs) are short, nonautonomous DNA elements that are widespread and abundant in plant genomes. Most of the hundreds of thousands of MITEs identified to date have been divided into two major groups on the basis of shared structural and sequence characteristics: Tourist-like and Stowaway-like. Since MITEs have no coding capacity, they must rely on transposases encoded by other elements. Two active transposons, the maize P Instability Factor (PIF) and the rice Pong element, have recently been implicated as sources of transposase for Tourist-like MITEs. Here we report that PIF- and Pong-like elements are widespread, diverse, and abundant in eukaryotes with hundreds of element-associated transposases found in a variety of plant, animal, and fungal genomes. The availability of virtually the entire rice genome sequence facilitated the identification of all the PIF/Pong-like elements in this organism and permitted a comprehensive analysis of their relationship with Tourist-like MITEs. Taken together, our results indicate that PIF and Pong are founding members of a large eukaryotic transposon superfamily and that members of this superfamily are responsible for the origin and amplification of Tourist-like MITEs.
