SOI/DRIE all-fiber optical switch for high-power applications (2003)

An all-fiber optical switch based on silicon on insulator (SOI) and deep reactive-ion etching (DRIE) technology has been developed. The novel switch is designed for applications requiring high optical power transfer, such as routing in optical energy conversion and transfer systems, while requiring low electrical power for switch actuation. The optical switch was realized by attaching a short optical fiber segment to a large-displacement microactuator, suspended between fixed input and output optical fibers. When the fibers are coaxially aligned, optical transfer is achieved between the fixed input and output fibers. The present work offers the potential for low electrical power operation, high-density array fabrication, fully-integrated manufacturing, and decoupled electromechanical/optical performance. The device concept and fabrication process is described, and optical transfer efficiency results are discussed. Current switches employ integrated electrothermal actuators to move the intermediate optical fiber segment, and switches based on lower-power electrostatic actuators will also be described.
Small-angle neutron scattering study of high-pressure sintered detonation nanodiamonds (2011)

The structure of detonation diamonds sintered at a high pressure (7 GPa) and temperatures of 1200–1700°C has been investigated by small-angle neutron scattering. It is shown that sintering leads to an increase in the particle size from 6 to 30 nm and established that this increase is due to the chainlike oriented attachment of particles. This study supplements the oriented-attachment model, which was suggested based on the X-ray diffraction spectra of detonation nanodiamonds (DNDs) sintered under the same conditions.
Reacquisition of virulence of haemolysin-negative Listeria monocytogenes mutants by complementation with a plasmid carrying the hlyA gene. (1989)

An haemolysin negative mutant of Listeria monocytogenes LO28 produced by insertion of Tn917 resulted in an avirulent derivative. The hlyA gene of the same strain was previously cloned in Escherichia coli and retransfered by transformation to the hly- derivative, after subcloning in the shuttle vector pMK4. The transformant strain (L828) reacquired an haemolytic activity at a similar level than the wild strain. The virulence of this hly+ transformant was estimated by determining the LD50 in Swiss mice infected intravenously. With increasing doses of bacteria a hly- control strain (transformant with only pMK4) appeared to be totally avirulent; however, no significant difference in virulence was found between the hly+ transformants and the wild strain. Seriol viable counts in the liver and spleen of infected mice demonstrated an increase in number of L828 hly+ transformants at 48 h, but the hly- control transformants were rapidly eliminated. These results confirm that the production of haemolysin is a major factor in the pathogenic capabilities of L. monocytogenes.
All-Optical Selective Wavelength Shifter in a SOA-MZI (2011)

Simultaneous selective wavelength conversion and data erasing of a burst of data under an optical gate in a single SOA-MZI is experimentally demonstrated. Error free operation at 10 Gb/s without any bit loss is reported.
Activated THP-1 Cells: an Attractive Model for the Assessment of Intracellular Growth Rates ofMycobacterium tuberculosisIsolates (2004)

Capacity of certain Mycobacterium tuberculosis isolates to grow more rapidly in human macrophages may be indicative of increased virulence. Significant differences were observed in intracellular growth of two isolates from sites of tuberculosis transmission, with an outbreak-associated strain growing faster than a strain causing disease in only one person. Activated THP-1 cells are a suitable alternative to peripheral blood monocyte models.

Wear Studies on Moldings of Polytetrafluoroethylene Resin. Considerations of Crystallinity and Graphite Content (1963)

The wear of molded bearings of polytetrafluoroethylene resin has been investigated in relation to crystallinity and filler content (graphite) as factors effecting changes in selected mechanical properties. In a homogeneous, unfilled resin molding, the rate of wear increases in direct proportion to the modulus in flexure and inversely with yield strain. A useful, simple expression is proposed to describe this relationship. In a heterogeneous, graphite-filled molding at a low filler content, the rate of wear initially approximates that of the homogeneous unfilled system and then decreases with time; at moderate, filler content, the wear rate is constant at levels below that of the unfilled resin. The rate of wear is also proportional to the applied load at low loading under conditions where bearing temperature remains reasonably constant; the wear data indicate the importance of removing frictional heat especially at high bearing loads. Practical suggestions are included for design for efficient bearings.
Propagation characteristics of horizontally and vertically polarized electric fields in an indoor environment: simple model and results (2002)

This paper presents measurement results that demonstrate the different propagation characteristics of the vertical and horizontal polarizations and their crosscorrelation coupling under line-of-sight and non-line-of-sight conditions. We also present a simplified model for the propagation environment that uses an approach similar to the method of images, and achieves results that match the measurements.
A Proteomic Approach to Apoplastic Proteins Involved in Cell Wall Regeneration in Protoplasts of Arabidopsis Suspension-cultured Cells (2005)

To clarify the mechanisms of cell wall construction, we used a proteomic approach to investigate the proteins secreted into cell wall spaces during cell wall regeneration from the protoplasts of Arabidopsis suspension-cultured cells. We focused on cell wall proteins loosely bound to the cell wall architecture and extractable with 1 M KCl solutions from: (i) native suspension cultured cells; (ii) protoplasts that had been allowed to regenerate their cell walls for 1 h; and (iii) protoplasts allowed to regenerate their cell walls for 3 h. We adopted a non-destructive extraction procedure without disrupting cellular integrity, thereby avoiding contamination from cytoplasmic proteins. Using two-dimensional polyacrylamide gel electrophoresis (2-D PAGE) and matrix-assisted laser desorption ionization-time-of-flight/mass spectrometry (MALDI-TOF/MS), we separated, mapped and identified 71 proteins derived from the native cell wall, and 175 and 212 proteins derived from the 1 and 3 h regenerated protoplasts, respectively. Quite different sets of proteins with differing status of their post-translational modifications, including phosphorylation and glycosylation, were identified in the three protein fractions. This indicated dynamic in muro changes in the cell wall proteins during cell wall regeneration in the protoplasts. The analysis revealed a set of enzymes specifically involved in cell wall expansion and construction in suspension-cultured cells. This approach has also determined a set of cell wall proteins that had not been predicted to be localized in cell wall spaces.
Zero-Field Electron Magnetic Resonance in Some Inorganic and Organic Radicals (1963)

Zero-field electron magnetic resonance (EMR) spectra have been observed for several dilute paramagnetic systems. Among these are peroxylamine disulfonate ions in aqueous solutions, Cr3+ in single crystals of MgO, free radicals in x-irradiated powders of malonic acid, potassium hydrogen malonate, dipotassium malonate, succinic acid, and glutaconic acid. Zero-field spectra were observed by means of a marginal oscillator—detector similar to that of Benedek and Kushida. The zero-field splittings in the systems studied were due exclusively to the hyperfine couplings between electronic and nuclear spins. Results obtained were in good agreement with high-field EMR measurements on these systems. In several cases the hyperfine couplings were obtained with greater precision than at high field. In addition, the radical —OOC–ĊH–COO— was identified, for the first time, in irradiated dipotassium malonate by means of its zero-field spectrum. No zero-field lines could be detected in electron-irradiated polyethylene. Advantages and disadvantages of the zero-field technique are discussed.
Ag/Au Mixed Sites Promote Oxidative Coupling of Methanol on the Alloy Surface (2014)

Nanoporous gold, a dilute alloy of Ag in Au, activates molecular oxygen and promotes the oxygen-assisted catalytic coupling of methanol. Because this trace amount of Ag inherent to nanoporous gold has been proposed as the source of oxygen activation, a thin film Ag/Au alloy surface was studied as a model system for probing the origin of this reactivity. Thin alloy layers of Ag(x)Au(1-x), with 0.15≤x≤0.40, were examined for dioxygen activation and methanol self-coupling. These alloy surfaces recombine atomic oxygen at different temperatures depending on the alloy composition. Total conversion of methanol to selective oxidation products, that is, formaldehyde and methyl formate, was achieved at low initial oxygen coverage and at low temperature. Reaction channels for methyl formate formation occurred on both Au and Au/Ag mixed sites with a ratio, as was predicted from the local 2-dimensional composition.
Bio-inspired Plasmonic Nanoarchitectured Hybrid System Towards Enhanced Far Red-to-Near Infrared Solar Photocatalysis (2016)

Solar conversion to fuels or to electricity in semiconductors using far red-to-near infrared (NIR) light, which accounts for about 40% of solar energy, is highly significant. One main challenge is the development of novel strategies for activity promotion and new basic mechanisms for NIR response. Mother Nature has evolved to smartly capture far red-to-NIR light via their intelligent systems due to unique micro/nanoarchitectures, thus motivating us for biomimetic design. Here we report the first demonstration of a new strategy, based on adopting nature's far red-to-NIR responsive architectures for an efficient bio-inspired photocatalytic system. The system is constructed by controlled assembly of light-harvesting plasmonic nanoantennas onto a typical photocatalytic unit with butterfly wings' 3D micro/nanoarchitectures. Experiments and finite-difference time-domain (FDTD) simulations demonstrate the structural effects on obvious far red-to-NIR photocatalysis enhancement, which originates from (1) Enhancing far red-to-NIR (700~1200 nm) harvesting, up to 25%. (2) Enhancing electric-field amplitude of localized surface plasmon (LSPs) to more than 3.5 times than that of the non-structured one, which promotes the rate of electron-hole pair formation, thus substantially reinforcing photocatalysis. This proof-of-concept study provides a new methodology for NIR photocatalysis and would potentially guide future conceptually new NIR responsive system designs.

Glomerular and Tubular Epithelial Defects in <i>kd/kd</i> Mice Lead to Progressive Renal Failure (2005)

The results suggest that the defect in kd/kd mice primarily affects both the tubular and glomerular visceral epithelium. The tubular epithelial defect triggers autoimmune interstitial nephritis, whereas a defect in podocytes leads to proteinuria and glomerulosclerosis. Thus, a single mitochondrial abnormality may result in differences in disease expression that vary with the type of epithelial cells. It is likely that the mitochrondrial perturbations in glomerular and tubular epithelia act in concert, through activation of different pathologic pathways, to accelerate disease progression leading to renal failure.
Efd-C(13)03/19 Neoclassical And Turbulent Transport Of W In Toroidally Rotating Jet Plasmas (2013)

The physical understanding of the transport of heavy impurities, like W, is important for the achievement of practical fusion energy. Among the plasma parameters which affect impurity transport, rotation has only recently received the deserved consideration. In addition to the off-diagonal contribution related to the presence of a radial gradient of the toroidal rotation (usually dubbed roto­diffusion), even in moderately rotating plasmas, centrifugal effects of heavy impurities become non-negligible. Plasmas obtained in the hybrid scenario in JET with the ITER-like wall (JETILW) can be used to study these effects on W, since the deuterium toroidal rotation reaches central thermal Mach numbers around 0.4 (Mach of W up to 3.8). At the same time, this study allows us to explore the transport mechanisms which are responsible for the central W accumulation which is often observed in this type of discharges.
Effect of Oral Drenching with Zinc Oxide or Synthetic Zeolite A on Total Blood Calcium in Dairy Cows (2001)

Danish Holstein dairy cows in late lactation and milked in the morning only were used as a model for dry pregnant cows to determine the effect of oral drenching with zeolite A and zinc oxide, respectively, on total serum calcium. Ten cows were assigned randomly to two groups of five cows each, given either synthetic zeolite A (group A) or zinc oxide (group B). Blood samples were drawn daily at 10 a.m. and 10 p.m. during the whole experiment, and total serum calcium was determined. Daily fluctuations in blood calcium were recorded, with morning values being consistently lower than evening values. Oral drenching with a single dose of zinc oxide of 100 mg/kg of body weight as well as with zeolite in doses of 500 g of zeolite/cow twice a day for 2.5 d was reflected in serum calcium levels. In the group given zeolite A, there was a depression in evening values of total serum calcium although the difference did not reach statistical significance. It was followed by an increase above baseline level ("overshooting"). This was interpreted as a response from the calcium homeostatic mechanisms. In the group given a single dose of zinc oxide, a decrease in total serum calcium occurred. This decrease was not followed by overshooting, indicating that the single treatment with zinc oxide did not stimulate the calcium homeostatic mechanisms. The perspective of this first attempt to reduce dry cow ration calcium availability may be seen in relation to difficulties in formulating dry cows rations from home grown forage sufficiently low in calcium to elicit a hypocalcemia protective response at calving.
A method of lumbar pedicle screw placement optimization applied to guidance techniques (2016)

Pedicle screws are an established method for spinal segmental fixation. To pursue high accuracy and minimally invasive, various different guidance techniques have developed. However, the preoperative screw position plans are determined by manual selection which demands complex operations and costs a lot of time. In addition, the current paths planning only consider the position, without taking the postoperative screws retention into consideration. In order to solve the problems, a new method was proposed to plan the lumbar pedicle screw placement automatically. Firstly, identify pedicle area and establish initial path based on the current vertebrae segmentation technology. After that, optimize path via the improved boundary limited Nelder–Mead simplex algorithm, and get the highest firmness path in theory. We considered that both the accuracy of position and the firmness of postoperative screws, achieved a fully automatic optimal path planning, which can effectively assist operators, improve the firmness of screw placement.
Electrical conductivity, thermopower, and Hall effect ofTi3AlC2,Ti4AlN3,andTi3SiC2 (2000)

In this paper we report on the thermopower and electrical conductivities of ${\mathrm{Ti}}_{4}{\mathrm{AlN}}_{2.9}$ and ${\mathrm{Ti}}_{3}{\mathrm{Al}}_{1.1}{\mathrm{C}}_{1.8}$ in the 300--850 K temperature range. We also measured the room temperature Hall effect in ${\mathrm{Ti}}_{3}{\mathrm{SiC}}_{2},$ ${\mathrm{Ti}}_{4}{\mathrm{AlN}}_{2.9},$ and ${\mathrm{Ti}}_{3}{\mathrm{Al}}_{1.1}{\mathrm{C}}_{1.8}.$ Based on these results we conclude that holes are the majority carriers at room temperature in ${\mathrm{Ti}}_{3}{\mathrm{Al}}_{1.1}{\mathrm{C}}_{1.8}$ and ${\mathrm{Ti}}_{4}{\mathrm{AlN}}_{2.9}.$ At higher temperatures free electrons contribute to the transport properties. ${\mathrm{Ti}}_{3}{\mathrm{SiC}}_{2}$ is a mixed conductor wherein the concentrations and mobilities of the free electrons are, respectively, equal to those of the holes over an extended temperature range. The high conductivity of ${\mathrm{Ti}}_{3}{\mathrm{SiC}}_{2}$ is due to the presence of a large concentration of charge carriers. The lower conductivity of ${\mathrm{Ti}}_{3}{\mathrm{Al}}_{1.1}{\mathrm{C}}_{1.8}$ is due to a dearth of charge carriers. The even lower conductivity of ${\mathrm{Ti}}_{4}{\mathrm{AlN}}_{2.9}$ is attributed to a reduced mobility, most probably due to vacancy scattering of the charge carriers.

APD3: the antimicrobial peptide database as a tool for research and education (2015)

The antimicrobial peptide database (APD, http://aps.unmc.edu/AP/) is an original database initially online in 2003. The APD2 (2009 version) has been regularly updated and further expanded into the APD3. This database currently focuses on natural antimicrobial peptides (AMPs) with defined sequence and activity. It includes a total of 2619 AMPs with 261 bacteriocins from bacteria, 4 AMPs from archaea, 7 from protists, 13 from fungi, 321 from plants and 1972 animal host defense peptides. The APD3 contains 2169 antibacterial, 172 antiviral, 105 anti-HIV, 959 antifungal, 80 antiparasitic and 185 anticancer peptides. Newly annotated are AMPs with antibiofilm, antimalarial, anti-protist, insecticidal, spermicidal, chemotactic, wound healing, antioxidant and protease inhibiting properties. We also describe other searchable annotations, including target pathogens, molecule-binding partners, post-translational modifications and animal models. Amino acid profiles or signatures of natural AMPs are important for peptide classification, prediction and design. Finally, we summarize various database applications in research and education.
Ubiquitin accumulation in autophagy-deficient mice is dependent on the Nrf2-mediated stress response pathway: a potential role for protein aggregation in autophagic substrate selection (2010)

Genetic ablation of autophagy in mice leads to liver and brain degeneration accompanied by the appearance of ubiquitin (Ub) inclusions, which has been considered to support the hypothesis that ubiquitination serves as a cis-acting signal for selective autophagy. We show that tissue-specific disruption of the essential autophagy genes Atg5 and Atg7 leads to the accumulation of all detectable Ub-Ub topologies, arguing against the hypothesis that any particular Ub linkage serves as a specific autophagy signal. The increase in Ub conjugates in Atg7(-/-) liver and brain is completely suppressed by simultaneous knockout of either p62 or Nrf2. We exploit a novel assay for selective autophagy in cell culture, which shows that inactivation of Atg5 leads to the selective accumulation of aggregation-prone proteins, and this does not correlate with an increase in substrate ubiquitination. We propose that protein oligomerization drives autophagic substrate selection and that the accumulation of poly-Ub chains in autophagy-deficient circumstances is an indirect consequence of activation of Nrf2-dependent stress response pathways.

Studies on pyrazine derivatives. XLVII. Synthesis and antibacterial activity of novel pyrazine derivatives with amidoxime moiety. (2007)

The new pyrazine derivatives exhibiting an antibacterial activity have been synthesized. Initial amidoxime 1 was obtained in the reaction of pyrazinecarbonitrile with hydroxylamine. Upon treatment of amidoxime with methyl iodide O-methyl derivative 2 was formed. Both amidoximes were transformed into imidoyl chlorides 3, 4. Then the chloride atom in those derivatives was substituted with various secondary amines giving appropriate oximes 5-18 and O-methyl-oximes 19 and 20. The obtained compounds were tested in vitro for their tuberculostatic activity. The inhibiting concentration (MIC) values were within 25-100 microg/mL. Their activity towards 25 strains of anaerobic and 25 strains of aerobic bacteria was also studied. Three compounds exhibited activity against both types of bacteria.

Evolving multi-tenant SaaS applications through self-adaptive upgrade enactment and tenant mediation (2016)

When successful, multi-tenant SaaS applications service many customer organizations (tenants) at once, and SaaS providers face the challenge of complying to the different SLAs of each of these tenants. As a consequence, evolving a SaaS application is in practice done at run time to limit service disruptions, and preferably on a gradual, tenant-pertenant basis, while taking into account the nature of the upgrade at hand but also these different tenant SLAs.
