coronary artery s tents: Effect of an Integrated Circuit Detector with Iterative Reconstruction 1 (2015)

By using a moving heart phantom, 18 data sets obtained from three coronary artery stents with small diameters were investigated. A second-generation dual-source CT system equipped with an integrated-circuit detector was used. Images were reconstructed with filtered back-pro jection (FBP) and IR at a section thickness of 0.75 mm (FBP75 and IR75, respectively) and IR at a section thickness of 0.50 mm (IR50). Multirow intensity profiles in Hounsfield units were modeled by using a sum-of-Gauss ians fit to analyze in-plane image characteristics. Out-ofplane image characteristics were analyzed with z upslope of multicolumn intensity profiles in Hounsfield units. Sta tistical analysis was conducted with one-way analysis of
Selective radical amination of aldehydic C(sp2)–H bonds with fluoroaryl azides via Co(ii)-based metalloradical catalysis: synthesis of N-fluoroaryl amides from aldehydes under neutral and nonoxidative conditions (2014)

The Co(II) complex of the <i>D</i><sub>2h</sub>-symmetric amidoporphyrin 3,5-Di <i><sup>t</sup></i> Bu-IbuPhyrin, [Co(<b>P1</b>)], has proven to be an effective metalloradical catalyst for intermolecular amination of C(sp<sup>2</sup>)-H bonds of aldehydes with fluoroaryl azides. The [Co(<b>P1</b>)]-catalyzed process can employ aldehydes as the limiting reagents and operate under neutral and non-oxidative conditions, generating nitrogen gas as the only byproduct. The metalloradical aldehydic C-H amination is suitable for different combinations of aldehydes and fluoroaryl azides, producing the corresponding <i>N</i>-fluoroaryl amides in good to excellent yields. A series of mechanistic studies support a stepwise radical mechanism for the Co(II)-catalyzed intermolecular C-H amination.
Studies on 2-oxoquinoline derivatives as blood platelet aggregation inhibitors. II. 6-(3-(1-Cyclohexyl-5-tetrazolyl)propoxy)-1,2-dihydro-2-oxoquinoline and related compounds. (1983)

A series of ω-(1-substituted-5-tetrazolylalkoxy)-2-oxoquinolines was synthesized and tested for inhibitory activity towards collagen-and adenosine diphosphate (ADP)-induced aggregation of rabbit blood platelets in vitro. These compounds were prepared by the reaction of 1-substituted-5-(ω-chloroalkyl)-tetrazoles and hydroxy-2-oxoquinolines in the presence of a base. Among them, 6-[3-(1-cyclohexyl-5-tetrazolyl)propoxy]-1, 2-dihydro-2-oxoquinoline (IVb) was found to have the most potent inhibitory activity. The structure-activity relationships are discussed.
Low power memory design (2003)

In this paper, we present a novel design procedure for multi-module, multi-port memory design that satisfies area and/or energy/timing constraints. Our procedure consists of (i) use of storage bandwidth optimization (SBO) techniques to simplify the conflict graph and (ii) use of memory exploration techniques to determine the best memory configuration (number of modules, size and number of ports per module) with the minimum area if the energy and timing are bounded or with the minimum energy/timing if the area is bounded. Here the simplest conflict graph implies more possibilities for the arrays assigned to the same module without the penalty in an increase of the number of ports for each module. Our benchmark shows that the heuristic algorithm is very efficient to decide the best memory configuration for the system constraints (timing, area, or energy). In addition, the CACTI tool (Premkishore Shivakumar and N.P. Jouppi, 2001) is modified to estimate the timing, area, and energy for each module in different CMOS technologies (0.8 /spl mu/m, 0.35 /spl mu/m, and 0.18 /spl mu/m). Furthermore, we consider the lifetime for arrays; this results in significant reduction in timing, area, and energy for the arrays executed in different cycles sharing the same memory module.
Use of antimicrobials in food-producing animals in Switzerland and in the European Union (EU) (2015)

The intensive and inappropriate use of antibiotics in both medicine and agriculture
has selected for antibiotic resistant bacteria that cause severe problems in
antibiotic therapy. In animal husbandry, antibiotics are used for therapeutic and
preventive treatments of infectious diseases and as growth promoters. In Europe,
many antibiotics used as growth promoters were of the same classes as important
antibiotics used in human medicine. The European Union withdrew the authorization
for the use of the major antimicrobial growth promoters between 1996 and
1999. In 1999 Switzerland decided to ban the use of all antimicrobials as growthpromoting
feed additives. The regulations concerning antibiotic use in animal husbandry
and the chronological reasons for the ban of antimicrobial growth promoters
are described. This ban led to a decrease of the antibiotic volume deployed in
agriculture. This measure helps to reduce the amount of antibiotic resistant bacteria
in food-producing animals. However, the use of medicated feed is still a common
practice to prevent and to remedy bacterial infections and thus still leads to resistant
pathogens. Surveillance programs, single animal treatment, good manufacturing
practices and vaccinations are additional measures to be taken to keep the level of
resistances in bacteria low.

Dynamic dispatch and graphical monitoring system (2002)

This paper presents the development and implementation of Motorola's graphical manufacturing monitoring system (GraMMS) that provides real-time graphical monitoring of manufacturing data including work-in-process (WIP), equipment, throughput, and dispatch rankings. GraMMS consists of four main applications namely; dynamic dispatch, WIP monitoring system (WMS), equipment management system (EMS), and throughput monitoring system (TMS). GraMMS (Pierce and Yurtsever, 1997) provides Motorola semiconductor wafer fabs with instant data-driven decision support and trend analysis as well as a short-interval scheduler via discrete-event simulation. The dynamic dispatch system is a combination of simulation and heuristics based on concepts from the theory of constraints. This competitive advantage increases output, decreases cycle time, and improves resource utilization.
The phase transition and elastic and optical properties of polymorphs of CuI (2012)

The high-pressure polymorphs of CuI have attracted much attention due to the somewhat contradictory identification of their structures by means of x-ray diffraction measurements and theoretical calculations. In this paper, we report the results of a theoretical investigation of polymorphs of CuI including zinc-blende, rhombohedral, tetragonal, rocksalt and orthorhombic phases. We find that CuI follows the high-pressure transition path from the zinc-blende phase to the orthorhombic phase via the tetragonal phase, and the rhombohedral phase shows mechanical instability under high pressure. The bulk moduli are almost isotropic but the shear moduli show large anisotropy in these polymorphs. A relatively strong hybridization of I p and Cu d states appears to determine the electronic properties of the CuI polymorphs. The zinc-blende and tetragonal CuI are direct gap semiconductors and their optical properties are similar, whereas the orthorhombic CuI is metallic.
Data Anonymization for Maintenance Knowledge Sharing (2021)

Formerly considered part of general enterprise costs, industrial maintenance has become critical for business continuity and a real source of data. Despite the heavy investments made by companies in smart manufacturing, traditional maintenance practices still dominate the industrial landscape. Maintenance knowledge sharing between industries can significantly optimize maintenance activity and improve process efficiency. Different international standards and initiatives are promoting such an approach. However, this trend failed to gain ground in the manufacturing industry. In this article, we present the results of our investigation about the real roadblocks that obstruct the progress of the maintenance knowledge sharing approach. We determined that knowledge graphs and, more importantly, automated data anonymization techniques can facilitate the development of general-purpose solutions to share maintenance knowledge among concerned actors.
Impact of linkers on the structural diversity of 3d-4f coordination polymers (2005)

One of the aims of crystal engineering is to produce extended frameworks utilising the wide range of possible covalent and supramolecular interactions. While the most common of the latter is probably the hydrogen bond (often used to generate organic as well as inorganic frameworks) a number of other interactions exist. Changes in experimental conditions may also influence the materials produced.
Imidazolium-Based Ionic Liquid Surfaces for Biosensing (2013)

Ionic liquid self-assembled monolayers (SAM) were designed and applied for binding streptavidin, promoting affinity biosensing and enzyme activity on gold surfaces of sensors. The synthesis of 1-((+)-biotin)pentanamido)propyl)-3-(12-mercaptododecyl)-imidazolium bromide, a biotinylated ionic liquid (IL-biotin), which self-assembles on gold film, afforded streptavidin sensing with surface plasmon resonance (SPR). The IL-biotin-SAM efficiently formed a full streptavidin monolayer. The synthesis of 1-(carboxymethyl)-3-(mercaptododecyl)-imidazoliumbromide, a carboxylated IL (IL-COOH), was used to immobilize anti-IgG to create an affinity biosensor. The IL-COOH demonstrated efficient detection of IgG in the nanomolar concentration range, similar to the alkylthiols SAM and PEG. In addition, the IL-COOH demonstrated low fouling in crude serum, to a level equivalent to PEG. The IL-COOH was further modified with N,N'-bis (carboxymethyl)-l-lysine hydrate to bind copper ions and then, chelate histidine-tagged biomolecules. Human dihydrofolate reductase (hDHFR) was chelated to the modified IL-COOH. By monitoring enzyme activity in situ on the SPR sensor, it was revealed that the IL-COOH SAM improved the activity of hDHFR by 24% in comparison to classical SAM. Thereby, IL-SAM has been synthesized and successfully applied to three important biosensing schemes, demonstrating the advantages of this new class of monolayers.
Delayed non-infectious lung disease in allogeneic bone marrow transplant recipients. (2001)

DLDs represent a group of entities heterogeneous in regard to variables such as onset and clinical behaviour (acute, subacute or chronic), predominant pattern of lung involvement (airway or parenchymal), response to treatment. Although immunopathologic mechanisms related to c-GVHD probably have a relevant pathogenic importance in this setting, the possible role of associated events (eg, drug toxicity and infections) at least in priming the lung damage need to be better clarified for its therapeutical implications.

Differential Effects of β3‐ versus β2‐Amino Acid Residues on the Helicity and Recognition Properties of Bim BH3‐Derived α/β‐Peptides (2018)

Oligomers containing α- and β-amino acid residues (α/β-peptides) have been shown to mimic the α-helical conformation of conventional peptides when the unnatural residues are derived from β<sup>3</sup> -amino acids or cyclic β-amino acids, but the impact of incorporating β<sup>2</sup> residues has received little attention. The effects of β<sup>2</sup> residues on the conformation and recognition behavior of α/β-peptides that mimic an isolated α-helix were investigated. This effort has focused on 26-mers based on the Bim BH3 domain; a set of isomers with identical α/β backbones that differ only in the placement of certain side chains along the backbone (β<sup>3</sup> vs. β<sup>2</sup> substitution) was compared. Circular dichroism data suggest that β<sup>2</sup> residues can be helix-destabilizing relative to β<sup>3</sup> residues, although the size of this effect seems to depend on side chain identity. Binding data show that β<sup>3</sup> →β<sup>2</sup> substitution at sites that contact a partner protein, Bcl-x<sub>L</sub> , can influence affinity in a way that transcends effects on helicity.
Expression and deletion analysis of the Trypanosoma brucei rhodesiense cysteine protease in Escherichia coli (1991)

Trypanosoma brucei, the cause of African sleeping sickness, differentiates in the mammalian bloodstream from a long, slender trypanosome into a short, stumpy trypanosome. This event is necessary for infection of the tsetse fly and maintenance of the life cycle. We have previously shown that the stumpy form contains 10- to 15-fold-greater cysteine protease activity than either the slender form or the insect midgut procyclic, and we have isolated a cDNA encoding the protease. In order to determine whether the cDNA encodes the developmentally regulated cysteine protease, we have purified the protease from trypanosomes and have made a polyclonal antiserum against it. The trypanosomal protease gene was then expressed in Escherichia coli with three different methionines within the pre- and propeptides acting as initiation sites. In each case, a protein was synthesized that was recognized by an antiserum specific for the developmentally regulated trypanosomal cysteine protease. The protein synthesized from the more upstream initiation site within the propeptide was proteolytically active. The recombinant protease and the trypanosomal enzyme were identical with respect to peptide substrates and protease inhibitors. The protein remained active when synthesized in a truncated form lacking the nine consecutive prolines and carboxy-terminus extension, indicating that the terminal 108 amino acids are not necessary for proteolytic activity.
Efficiency improvement of converter for switched reluctance motor drives by mixed parallel operation of IGBT and MOSFET (2010)

This paper presents a method to improve the efficiency of a standard asymmetric half-bridge converter for 3-phase, 12/8 switched reluctance motor (SRM) drives at low speed operation. At that speed range, the converter operates mainly in current chopping modes. The proposed method employs mixed parallel operation of IGBT/MOSFET pairs. The technique is aiming for minimizing the turn-off switching losses of IGBT which are the main chopping switches. MOSFET are placed in parallel with each IGBT in order to momentarily conduct the phase current during IGBT's turn-off intervals. While the MOSFET is on, the voltage across the IGBT is close to zero resulting in substantially decreased turn-off loss. Those fast switching MOSFET later instantaneously turn-off the current with almost lossless. The algorithm is verified by computer simulation and experimental results. The results have satisfactorily shown validity of the proposed concept. Furthermore, performance of the proposed strategy is superior to those of the typical hard switching technique and the conventional soft switching scheme using optimum sized snubber capacitors.
Highly efficient x-ray imaging and backlighting schemes based on spherically bent crystals (2004)

New approaches of a spectrally tunable backlighting schemes based on a spherically bent crystal are considered. In a contrary to the traditional backlighting scheme, in which the investigated objects should be placed between the backlighter and the crystal, for the considered schemes an object is placed downstream of the crystal, before the tangential or after the sagittal focus and an image of the object is recorded at the distance from the object corresponded to the needed magnification. The magnification is defined by the ratio of the distances form the sagittal focus to the detector and from the object to the sagittal focus. A ray tracing modeling and experimental images of test meshes, obtained at an incidence angles of the backlighter radiation of 10° and 22°, are presented. It is demonstrated that, at incident angles up to 22°, a linear transformation of the obtained astigmatic images allows to reconstruct them with an accuracy (5 - 15%). A spatial resolution around 10 &#956;m in a field of view of some mm<sup>2</sup> is achieved, for the spectral range around 9 &angst;. It is also demonstrated that spherically bent crystals could be used for X-ray imaging of a self emitting plasma structures with a spatial resolution at least 50 &#956;m in a field of view of some square millimeters for angles of incidence up to 22°.

A Centralized Reactive Power Compensation System for LV Distribution Networks (2014)

A centralized reactive power compensation system is proposed for low voltage (LV) distribution networks. It can be connected with any bus which needs reactive power. The current industry practice is to locally install reactive power compensation system to maintain the local bus voltage and power factor. By centralizing capacitor banks together, it can help to maintain bus voltages and power factors as well as reduce the power cable losses. Besides, the centralized reactive power system can be easily expanded to meet any future load increase. A reasonably sized centralized reactive power compensation system will be capable of meeting the requirements of the network and the optimization algorithm proposed in this paper can help to find this optimal size by minimizing the expected total cost ( ETCH). Different load situations and their respective probabilities are also considered in the proposed algorithm. The concept of the centralized reactive power compensation system is applied to a local shipyard power system to verify its effectiveness. The results show that an optimally sized centralized reactive power system exists and is capable of maintaining bus voltages as well as reducing the power losses in the distribution network. A significant power loss reduction can be obtained at the optimal capacity of the centralized reactive power compensation system in the case study.

Metal triflate-mediated coupling of allylgermanes with thiols: a facile route to thiogermanes (2015)

A novel coupling reaction of thiols with (2-methylallyl)germanes catalyzed by metal triflates has been developed. This reaction provides a direct and efficient method to afford thiogermanes and opens a valuable and general synthetic route for the Ge-S cross-coupling with the elimination of isobutylene as a single by-product. Scandium(iii) triflate demonstrates the highest catalytic activity among the tested triflates. All reactions were carried out under extremely mild conditions to give thiogermanes in excellent yields. This Ge-S coupling reaction shows high generality for the variety of thiols.

Synthesis of a high T/sub c/ superconducting phase in Bi-Sr-Ca-Cu-O system (1989)

The synthesis of a high-T/sub c/ phase in the Bi-Sr-Ca-Cu-O system by the solid-state reaction and the J/sub c/ characteristics are reported. The partial pressure of oxygen near 0.1 atm is preferable as a sintering atmosphere, and Pb addition is effective to produce a large amount of high-T/sub c/ phase. Two classes of amorphouslike metastable superconducting phases with T/sub c/ of approximately 90 K and approximately 40 K, respectively, are found. It is thought that they have a randomly stacked structure. J/sub c/ of 93 A/cm/sup 2/ at zero field, 77 K is obtained for the sample with T/sub c/( rho =0)=107 K, which includes a high-T/sub c/ phase and a small amount of a low-T/sub c/ phase covered with the former phase. J/sub c/ is exponentially decreased by increasing the field. It is found that the transport J/sub c/ is limited by the weak-link regions in this system, as evidenced by the observation of a low resistive state above the J/sub c/ and of superconductivity in that state.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">&gt;</ETX>
Fabrication of Submicron Feature Diffractive Elements using Near-Field Direct-Write Ultra-Violet Lithography (1996)

The fabrication of surface relief diffractive elements using a series of binary exposures and etches in photo-resist is attractive because it relies upon standard lithographic techniques [1]. Disadvantages of this process include the necessity for mask generation prior to photoresist exposure and the logarithmic relationship between the desired number of phase levels and number of exposures. To overcome the latter restriction, the generation of gray level masks has been proposed [2]. However, both restrictions can be overcome if the photoresist is exposed directly. Electron beam [3] and laser beam direct-write [4] procedures have been proposed. Electron beam writing is attractive for its high resolution and laser beam writing for its cost. Both high resolution and low cost are possible if a tapered fiber is used to deliver energy to the photoresist [5,6]. We report on the fabrication of diffractive gratings with submicron features using a tapered fiber to deliver ultra-violet (UV) energy to a layer of photoresist.
