Hydrothermal Preparation and Characterization of Luminescent CdWO<sub>4</sub> Nanorods (2000)

CdWO4 nanorods have been prepared through a hydrothermal method at 130 °C. CdWO4 showed very strong photoluminescence at 486 nm at room temperature with the excitation 253 nm. The TEM image of the sample shows that it was composed of monomorphologic nanorods with a size of 80−280 × 20−40 nm2. We investigated the influence of the different initial pH values on the photoluminescent intensity of the products. The results show that the emission intensity is related to the preparation conditions; however, the photoluminescence emission peak positions are independent of the initial conditions.

In collaboration with the Auto-ID Center, ThingMagic LLC has developed a unique multi-band RFID tag reader reference platform. This reader has been designed to read tags conforming to the the Auto-ID Center’s emerging EPC specifications at both the 13.56MHz (HF) and 902 – 928MHz (UHF) frequency bands. The hardware architecture consists of a general purpose analog front end up/downconverter for each band, followed by a software radio architecture allowing easy adaptation to new frequencies and protocols. The reader's modular software architecture allows easy expansion while at the same time providing sophisticated networking capabilities including Web configurability, dynamic firmware update, and a TCP/IP reader interface by means of an embedded SQL-compatible database engine. This design offers excellent scalability and flexibility allowing rapid deployment and an in-situ upgrade path.
Oxetanes as Versatile Elements in Drug Discovery and Synthesis (2010)

Sizable resources, both financial and human, are invested each year in the development of new pharmaceutical agents. However, despite improved techniques, the new compounds often encounter difficulties in satisfying and overcoming the numerous physicochemical and many pharmacological constraints and hurdles. Oxetanes have been shown to improve key properties when grafted onto molecular scaffolds. Of particular interest are oxetanes that are substituted only in the 3-position, since such units remain achiral and their introduction into a molecular scaffold does not create a new stereocenter. This Minireview gives an overview of the recent advances made in the preparation and use of 3-substituted oxetanes. It also includes a discussion of the site-dependent modifications of various physicochemical and biochemical properties that result from the incorporation of the oxetane unit in molecular architectures.
Prochlorperazine—Treatment for Acute Confusional Migraine (2008)

Acute confusional migraine is a rare migraine variant primarily seen in childhood that lacks standardized diagnostic criteria. Acute symptomatic treatment for this disorder has not been established. We report 2 patients having a total of 6 episodes of acute confusional migraine where the symptoms resolved with prochlorperazine with variable success. Intravenous prochlorperazine was highly effective in 3 out of 4 episodes.

CORUM: the comprehensive resource of mammalian protein complexes (2007)

Protein complexes are key molecular entities that integrate multiple gene products to perform cellular functions. The CORUM (http://mips.gsf.de/genre/proj/corum/index.html) database is a collection of experimentally verified mammalian protein complexes. Information is manually derived by critical reading of the scientific literature from expert annotators. Information about protein complexes includes protein complex names, subunits, literature references as well as the function of the complexes. For functional annotation, we use the FunCat catalogue that enables to organize the protein complex space into biologically meaningful subsets. The database contains more than 1750 protein complexes that are built from 2400 different genes, thus representing 12% of the protein-coding genes in human. A web-based system is available to query, view and download the data. CORUM provides a comprehensive dataset of protein complexes for discoveries in systems biology, analyses of protein networks and protein complex-associated diseases. Comparable to the MIPS reference dataset of protein complexes from yeast, CORUM intends to serve as a reference for mammalian protein complexes.
Automobile Damage Scales and the Effect on Injury Analysis (1992)

<div class="htmlview paragraph">A review of the biomechanics literature reveals that various parameters are used to correlate injury severity to collision severity. The primary measurement of crash severity is based upon vehicle damage. This is associated with energy loss and change of speed. However, there are a number of identification tools presently used for injury statistical purposes such as the police collision report description, TAD, VDI and CDC damage scales.</div> <div class="htmlview paragraph">This paper discusses the development of these damage scales and evaluates the correlation between them. Numerous descriptors are utilized in the available damage scales and include verbal, photographic, and diagram descriptions. Accident rates are correlated to the damage severity and compared to the CDC levels. Efficacy of using the current CDC damage scale is evaluated by comparing it with more sensitive damage ratings.</div>
Advanced Cooling for Power Electronics (2012)

Power electronics devices such as MOSFET's, GTO's, IGBT's, IGCT's etc. are now widely used to efficiently deliver electrical power in home electronics, industrial drives, telecommunication, transport, electric grid and numerous other applications. This paper discusses cooling technologies that have evolved in step to remove increasing levels of heat dissipation and manage junction temperatures to achieve goals for efficiency, cost, and reliability. Cooling technologies rely on heat spreading and convection. In applications that use natural or forced air cooling, water heat pipes provide efficient heat spreading for size and weight reduction. Previous concepts are reviewed and an improved heat sink concept with staggered fin density is described for more isothermal cooling. Where gravity can drive liquid flow, thermosiphons provide efficient heat transport to remote fin volumes that can be oriented for natural and/or forced air cooling. Liquid cold plates (LCP's) offer the means to cool high heat loads and heat fluxes including double sided cooling for the highest density packaging. LCP's can be used both in single phase cooling systems with aqueous or oil based coolants and in two-phase cooling systems with dielectric fluids and refrigerants. Previous concepts are reviewed and new concepts including an air cooled heat sink, a thermosiphon heat sink, a vortex flow LCP and a shear flow direct contact cooling concept are described.
Suppression of autophagy permits successful enzyme replacement therapy in a lysosomal storage disorder—murine Pompe disease (2010)

Autophagy, an intracellular system for delivering portions of cytoplasm and damaged organelles to lysosomes for degradation/recycling, plays a role in many physiological processes and is disturbed in many diseases. We recently provided evidence for the role of autophagy in Pompe disease, a lysosomal storage disorder in which acid alphaglucosidase, the enzyme involved in the breakdown of glycogen, is deficient or absent. Clinically the disease manifests as a cardiac and skeletal muscle myopathy. The current enzyme replacement therapy (ERT) clears lysosomal glycogen effectively from the heart but less so from skeletal muscle. In our Pompe model, the poor muscle response to therapy is associated with the presence of pools of autophagic debris. To clear the fibers of the autophagic debris, we have generated a Pompe model in which an autophagy gene, Atg7, is inactivated in muscle. Suppression of autophagy alone reduced the glycogen level by 50–60%. Following ERT, muscle glycogen was reduced to normal levels, an outcome not observed in Pompe mice with genetically intact autophagy. The suppression of autophagy, which has proven successful in the Pompe model, is a novel therapeutic approach that may be useful in other diseases with disturbed autophagy.
DiffCorr: An R package to analyze and visualize differential correlations in biological networks (2012)

Large-scale "omics" data, such as microarrays, can be used to infer underlying cellular regulatory networks in organisms, enabling us to better understand the molecular basis of disease and important traits. Correlation approaches, such as a hierarchical cluster analysis, have been widely used to analyze omics data. In addition to the changes in the mean levels of molecules in the omics data, it is important to know about the changes in the correlation relationship among molecules between 2 experimental conditions. The development of a tool to identify differential correlation patterns in omics data in an efficient and unbiased manner is therefore desirable. We developed the DiffCorr package, a simple method for identifying pattern changes between 2 experimental conditions in correlation networks, which builds on a commonly used association measure, such as Pearson's correlation coefficient. DiffCorr calculates correlation matrices for each dataset, identifies the first principal component-based "eigen-molecules" in the correlation networks, and tests differential correlation between the 2 groups based on Fisher's z-test. We illustrated its utility by demonstrating biologically relevant, differentially correlated molecules in transcriptome coexpression and metabolite-to-metabolite correlation networks. DiffCorr can explore differential correlations between 2 conditions in the context of post-genomics data types, namely transcriptomics and metabolomics. DiffCorr is simple to use in calculating differential correlations and is suitable for the first step towards inferring causal relationships and detecting biomarker candidates. The package can be downloaded from the following website: http://diffcorr.sourceforge.net/.
Two-element refracting system for annular Gaussian-to-Bessel beam transformation (1998)

A refracting system consisting of two lenses is designed to transform an annular Gaussian laser beam into a circular Bessel beam. The slopes of the input and output surfaces fit well with a sixth-order polynomial. A smooth variation of the radii of curvature of the resulting aspheric surfaces is very attractive for easy machining of the surfaces. The diffraction-free length for the designed system is 59.4735 m at 633 nm.
Adsorbate-Induced Silver Nanoparticle Aggregation Kinetics (2005)

Metal sols are often stabilized in solution by the presence of a charged double layer surrounding each colloidal nanoparticle that produces a coulomb barrier to aggregation. The nanoparticles can be induced to aggregate by replacing the charged surface species by uncharged adsorbate. We present a simple analysis that produces an expression for the initial rate constant describing the aggregation process, which is shown to depend nontrivially on the adsorbate concentration. The expression is tested experimentally by following and analyzing the time rate of decrease of the surface plasmon resonance absorption of isolated Ag nanoparticles in aqueous solution. The experimental result accords well with theory, producing a rough estimate of the (adsorbate-concentration dependent) barrier to aggregation that in the absence of added adsorbate is approximately equal to 0.08 eV.
Brain oxytocin receptors mediate ejaculation elicited by 7‐hydroxy‐2‐(di‐<i>N</i>‐propylamino) tetralin (7‐OH‐DPAT) in anaesthetized rats (2008)

Brain oxytocin receptors mediate male sexual responses elicited by i.c.v. 7-OH-DPAT in anaesthetized rats whereas L6 spinal oxytocin receptors only impair the occurrence of ejaculation. Peripheral oxytocin receptors are marginally involved in 7-OH-DPAT-induced sexual responses. These findings should be considered for the development of potential pharmacological treatment of premature ejaculation in man.
Recent Studies on the Regioselective C-Protonation of Enol Derivatives using Carbonyl-Containing Proton Donors (2001)

Enolate protonation can occur by two different pathways. With strong acids regioselective protonation generally occurs on the oxygen of the enolate to give an enol and then acid catalysed tautomerisation leads directly to the thermody-namically preferred carbonyl motif. However, with much weaker acids kinetic protonation on carbon can occur to give directly the carbonyl derivative. This review discuss recent developments into the use of chelating acids to promote this stereochemically important C-protonation and we comment on factors that appear to promote this selectivity.
A Single-Phase Single-Source 7-Level Inverter With Triple Voltage Boosting Gain (2018)

The cascaded H-bridge multilevel inverter (MLI) requires separate isolated dc sources to generate more than three voltage levels and to generate higher output voltage. This paper proposes a new MLI topology that requires only one dc source and is capable of generating seven voltage levels with triple voltage boosting gain. Three H-bridges are interconnected through two bidirectional voltage blocking switches to enable the integration of two switched-capacitors. Unlike the existing two-stage structure switched-capacitor-based MLI, the proposed MLI is a single-stage topology. It alleviates the voltage stress across switches such that low voltage stress of not more than the dc source voltage is ensured on all switches. In addition, capacitors voltage balancing is achieved automatically during operation. The operation of the proposed MLI is analyzed followed by verification through simulation and experimental test of a low power/voltage prototype.
3D structure of the Earth's lower mantle (2003)

We present an overview of the present knowledge of the Earth's lower mantle 3D structure, as currently obtained owing to progress, in the last ten years, in seismic tomography as well as forward modelling of seismic travel times and waveforms. We discuss constraints that seismic modelling brings to the debate concerning major geodynamical questions, in particular the issue of global ‘1 layer’ or ‘2 layer’ circulation, of the missing geochemical reservoir, as well as of the role in global dynamics of the thermochemical boundary layer at the base of the mantle.

Learning tag relevance by neighbor voting for social image retrieval (2008)

Social image retrieval is important for exploiting the increasing amounts of amateur-tagged multimedia such as Flickr images. Since amateur tagging is known to be uncontrolled, ambiguous, and personalized, a fundamental problem is how to reliably interpret the relevance of a tag with respect to the visual content it is describing. Intuitively, if different persons label similar images using the same tags, these tags are likely to reflect objective aspects of the visual content. Starting from this intuition, we propose a novel algorithm that scalably and reliably learns tag relevance by accumulating votes from visually similar neighbors. Further, treated as tag frequency, learned tag relevance is seamlessly embedded into current tag-based social image retrieval paradigms.
The effect of varactor non-linearity on the phase noise of a completely integrated 1.8 GHz VCO (2003)

This work discusses variations in phase noise over the tuning range. The circuit has a phase noise of /spl sim/101 dBc/Hz at 100 kHz offset, and delivers -2 dBm differentially. Calculations predict phase noise with only a small error.
Generation of Mucosal Anti-Human Immunodeficiency Virus Type 1 T-Cell Responses by Recombinant <i>Mycobacterium smegmatis</i> <sup>▿</sup> (2006)

A successful vaccine vector for human immunodeficiency virus type 1 (HIV-1) should induce anti-HIV-1 immune responses at mucosal sites. We have generated recombinant Mycobacterium smegmatis vectors that express the HIV-1 group M consensus envelope protein (Env) as a surface, intracellular, or secreted protein and have tested them in animals for induction of both anti-HIV-1 T-cell and antibody responses. Recombinant M. smegmatis engineered for expression of secreted protein induced optimal T-cell gamma interferon enzyme-linked immunospot assay responses to HIV-1 envelope in the spleen, female reproductive tract, and lungs. Unlike with the induction of T-cell responses, priming and boosting with recombinant M. smegmatis did not induce anti-HIV-1 envelope antibody responses, due primarily to insufficient protein expression of the insert. However, immunization with recombinant M. smegmatis expressing HIV-1 Env was able to prime for an HIV-1 Env protein boost for the induction of anti-HIV-1 antibody responses.
Synthesis and antibacterial properties of peptidyl derivatives and cyclopeptides structurally based upon the inhibitory centre of human cystatin C. Dissociation of antiproteolytic and antibacterial effectsNote (2000)

Cysteine protease-inhibiting proteins of the cystatin superfamily can inhibit the replication of certain viruses and bacteria. The inhibitory centre of human cystatin C, the most widely distributed human cystatin, comprises three peptide segments. The present work describes the synthesis and antibacterial activity of 27 new peptidyl derivatives or cyclopeptides based upon the aminoterminal segment Arg8-Leu9-Val10-Gly11. Fourteen of the new compounds displayed antibacterial activity against from 1 up to 9 of 17 clinically important bacterial species tested. Antiproteolytic activity of a compound was usually not required for its antibacterial capacity. Peptidyl diazomethanes generally had a very narrow antibacterial spectrum, inhibiting only Streptococcus pyogenes, whereas cyclopeptides and peptidyl derivatives of the general structure X-Arg-Leu-NH-CH(iPr)-CH2-NH-Y had a much wider spectrum. The most potent of these substances displayed approximately equal minimal inhibitory and bactericidal concentrations of about 20 microg/ml for both Staphylococcus aureus and S. pyogenes and were devoid of antiproteolytic activity. Several of the new substances could protect mice against lethal intraperitoneal challenge with S. pyogenes. Though their target remains to be disclosed, the group of substances here reported might be promising for the development of antibacterial drugs and the discovery of novel principles of action.

Detection and Processing of bistatically reflected GPS signals from low Earth orbit for the purpose of ocean remote sensing (2005)

We will show that ocean-reflected signals from the global positioning system (GPS) navigation satellite constellation can be detected from a low-earth orbiting satellite and that these signals show rough correlation with independent measurements of the sea winds. We will present waveforms of ocean-reflected GPS signals that have been detected using the experiment onboard the United Kingdom's Disaster Monitoring Constellation satellite and describe the processing methods used to obtain their delay and Doppler power distributions. The GPS bistatic radar experiment has made several raw data collections, and reflected GPS signals have been found on all attempts. The down linked data from an experiment has undergone extensive processing, and ocean-scattered signals have been mapped across a wide range of delay and Doppler space revealing characteristics which are known to be related to geophysical parameters such as surface roughness and wind speed. Here we will discuss the effects of integration time, reflection incidence angle and examine several delay-Doppler signal maps. The signals detected have been found to be in general agreement with an existing model (based on geometric optics) and with limited independent measurements of sea winds; a brief comparison is presented here. These results demonstrate that the concept of using bistatically reflected global navigation satellite systems signals from low earth orbit is a viable means of ocean remote sensing.
Far-Field Optical Hyperlens Magnifying Sub-Diffraction-Limited Objects (2007)

The diffraction limit of light, which is causd by the loss of evanescent waves in the far field that carry high spatial frequency information, limits the resolution of optical lenses to the order of the wavelength of light. We report experimental demonstration of the optical hyperlens for sub-diffraction-limited imaging in the far field. The device magnifies subwavelength objects by transforming the scattered evanescent waves into propagating waves in an anisotropic medium and projects the high-resolution image at far field. The optical hyperlens opens up possibilities in applications such as real-time biomolecular imaging and nanolithography.
