Temperature Dependence of Magnetic Flux Drag Torque for a Single Grain YBa2Cu3O7 Superconductor (2008)

A modified close cycle helium gas cryogenic system was used to measure the flux drag torque acting on a free spinning disk magnet by a single grain YBCO superconductor. It was found that at low spinning speed ( less than 8 Hz ) and constant levitation height, the flux drag torque decreased with temperature which behavior is roughly similar to the temperature dependence of the reciprocal of critical current density for a single grain superconductor.

Measurements of the top quark pair production cross section in pp collisions at 7 TeV using the CMS detector (2012)

Measurements of the top-pair production cross section in proton-proton collisions at the CMS Experiment at the LHC are presented. The data were collected at a centre-of-mass energy of 7 TeV. Measurements performed on an integrated luminosity of 36/pb of data collected in 2010 are presented in top anti-top quark pair final states with one or two leptons (muon or electron) and jets. Moreover, first measurements of the cross section for the production of top quark pairs are presented in the fully hadronic channel, and in the dilepton final state with one muon and one tau-lepton. These measurements make use of 1.1/fb of data recorded in 2011.
Electrochemical Control of the Interactions of Polymers and Redox-Active Surfactants (2005)

We report the characterization of aqueous solutions (0.1 M Li(2)SO(4)) of dilute ethyl(hydroxyethyl) cellulose (EHEC) mixed with the redox-active surfactant (11-ferrocenylundecyl)trimethylammonium bromide (FTMA) by measurements of clouding temperatures and dynamic light scattering. The investigation sought to test the hypothesis that FTMA, which forms micelles in aqueous solution in its reduced state but not in its oxidized state, would permit reversible control over the formation of polymer-surfactant complexes in solution. Our measurements revealed that low concentrations of reduced FTMA enhance aggregation, whereas high concentrations of reduced FTMA disperse polymer-surfactant aggregates. This behavior is qualitatively similar to both dodecyltrimethylammonium bromide and sodium dodecyl sulfate and reflects cooperative interactions between FTMA and EHEC. In contrast, oxidized FTMA was found not to promote EHEC aggregation at low concentrations of oxidized FTMA nor disperse EHEC aggregates at high concentrations. Measurements of dynamic light scattering revealed that the reduction of oxidized FTMA in solutions of EHEC containing 0.1-0.3 mmolal FTMA causes an increase in the sizes of polymer-surfactant aggregates of more than 1 order of magnitude. Our cloud point measurements also revealed that clouding can be induced isothermally via the electrochemical reduction of oxidized FTMA at room temperature at FTMA concentrations between 0.4 and 10 mmolal. In contrast, at concentrations of FTMA greater than 15 mmolal, the reduction of oxidized FTMA induces the clearing of EHEC solutions. We conclude that aggregation of EHEC in dilute solutions can be controlled by the manipulation of the oxidation state of FTMA.
Admission Fibrinolytic Profile Is Associated With Symptomatic Hemorrhagic Transformation in Stroke Patients Treated With Tissue Plasminogen Activator (2004)

Baseline PAI-1 and TAFI levels predict SICH after stroke tPA therapy. In the future, these biomarkers could be used to improve thrombolysis safety.
Anti-Sm Autoantibodies in Systemic Lupus Target Highly Basic Surface Structures of Complexed Spliceosomal Autoantigens (2002)

Autoantibodies directed against spliceosomal proteins are a common and specific feature of systemic lupus erythematosus. These autoantibodies target a collection of proteins, including Sm B, B', D1, D2, and D3. We define the common antigenic targets of Sm D2 and D3 and examine their role in spliceosomal autoimmunity. Our results define nine major common epitopes, five on Sm D2 and four on Sm D3. These epitopes have significantly higher (more basic) isoelectric points than do nonantigenic regions. In fact, this association is of sufficient power to make isoelectric point an excellent predictor of spliceosomal antigenicity. The crystallographic structure of Sm D2 and D3 is now partially described. The anti-Sm D2 and D3 antigenic targets are located on the surface of the respective three-dimensional complexed proteins, thereby suggesting that these epitopes are accessible in the native configuration. All but one of these nine epitopes conspicuously avoid the specific regions involved in intermolecular interactions within the spliceosomal complex. One of the D3 epitopes (RGRGRGMGR) has significant sequence homology with a major antigenic region of Sm D1 (containing a carboxyl-terminal glycine-arginine repeat), and anti-D3 Abs cross-react with this epitope of Sm D1. These results demonstrate that spliceosomal targets of autoimmunity are accessible on native structure surfaces and that cross-reactive epitopes, as well as structural associations of various spliceosomal Ags, may be involved in the induction of autoimmunity in systemic lupus.
Linear and nonlinear propagation of optical Nyquist pulses in fibers (2012)

We present an analytical and numerical description of optical Nyquist pulse propagation in optical fibers in the presence of dispersion and nonlinearity. An optical Nyquist pulse has a profile given by the sinc-like impulse response of a Nyquist filter, which has periodic zero-crossing points at every symbol interval. This property makes it possible to interleave bits to an ultrahigh symbol rate with no intersymbol interference in spite of the strong overlap between adjacent pulses. We analyze how this periodic zero-crossing property is maintained or affected by the fiber dispersion and nonlinearity, and show that it is better maintained against nonlinearity in the presence of normal dispersion.
Human endothelial cells modulate granulocyte adherence and chemotaxis. (1985)

Although human endothelial cells (EC) and granulocytes interact in several ways, the factors that regulate such interactions are not well defined. In this study we found that EC and their products directly altered granulocyte adherence (GA) and chemotactic activity. The spontaneous adherence of granulocytes to human umbilical vein EC monolayers was significantly reduced at 5, 15 and 30 min if the granulocytes were preincubated with EC that were stimulated by rocking. At 30 min the spontaneous adherence of EC-preincubated granulocytes was 36% of that of control granulocytes (P = 0.004). The augmented adherence stimulated by FMLP was also decreased (54% of control) by preincubation of the granulocytes with rocked EC. The ability of stimulated EC to inhibit GA was attenuated when the EC monolayers that were used for preincubation with the granulocytes were pretreated with the cyclooxygenase inhibitor indomethacin. GA to unstimulated EC was not significantly altered by indomethacin or aspirin, suggesting that cyclooxygenase products do not influence GA under resting conditions. Preincubation of granulocytes with rocked EC monolayers or supernatant media from rocked EC monolayers diminished their chemotactic response to FMLP by 45 to 65. This inhibition was also attenuated by pretreatment of the EC with indomethacin. EC supernatant medium caused a rapid increase in granulocyte intracellular cyclic AMP, with a maximum increase to 200% of control at 1 min. These data indicate that stimulated EC release one or more arachidonic acid products that alter spontaneous and inflammatory mediator-stimulated granulocyte activity. Prostacyclin, a major cyclooxygenase product of EC arachidonate, depressed inflammatory mediator-augmented GA to EC monolayers and chemotaxis when present in nanomolar concentrations. We conclude that EC-derived prostacyclin, alone or in combination with other EC products, alters GA and chemotaxis stimulated by inflammatory mediators. This provides a mechanism by which EC may modulate granulocyte distribution as well as granulocyte responses that are influenced by adherence, such as the release of toxic oxygen metabolites and granular enzymes.
Structural analysis of chromosomal rearrangements associated with the developmental mutations Ph, W19H, and Rw on mouse chromosome 5. (1994)

We are studying the chromosomal structure of three developmental mutations, dominant spotting (W), patch (Ph), and rump white (Rw) on mouse chromosome 5. These mutations are clustered in a region containing three genes encoding tyrosine kinase receptors (Kit, Pdgfra, and Flk1). Using probes for these genes and for a closely linked locus, D5Mn125, we established a high-resolution physical map covering approximately 2.8 Mb. The entire chromosomal segment mapped in this study is deleted in the W19H mutation. The map indicates the position of the Ph deletion, which encompasses not more than 400 kb around and including the Pdgfra gene. The map also places the distal breakpoint of the Rw inversion to a limited chromosomal segment between Kit and Pdgfra. In light of the structure of the Ph-W-Rw region, we interpret the previously published complementation analyses as indicating that the pigmentation defect in Rw/+ heterozygotes could be due to the disruption of Kit and/or Pdgfra regulatory sequences, whereas the gene(s) responsible for the recessive lethality of Rw/Rw embryos is not closely linked to the Ph and W loci and maps proximally to the W19H deletion. The structural analysis of chromosomal rearrangements associated with W19H, Ph, and Rw combined with the high-resolution physical mapping points the way toward the definition of these mutations in molecular terms and isolation of homologous genes on human chromosome 4.
Combining background subtraction and three-frame difference to detect moving object from underwater video (2016)

Moving object detection is the basis of object tracking and classification in computer vision, which has been applied to underwater robots to execute underwater missions and do marine ecological research. The complicated scene and poor lighting condition in underwater environment usually make moving object detection difficult. To solve above problems and to detect moving object from underwater video, we propose an approach combining background subtraction and three-frame difference. In this method, firstly we detect moving object pixels by background subtraction and three-frame difference perspectively. Next, we perform "AND" operation on the results of background subtraction and three-frame difference, background subtraction provides the object information to supplement the incomplete information detected from three-frame difference. Lastly, morphology processing is utilized on the result to remove the noise caused by non-static objects in background. This method shows an effective and reliable performance in detecting moving object from underwater video.
Q-plates as higher order polarization controllers for orbital angular momentum modes of fiber (2015)

We demonstrate that a |q|=1/2 plate, in conjunction with appropriate polarization optics, can selectively and switchably excite all linear combinations of the first radial mode order |l|=1 orbital angular momentum (OAM) fiber modes. This enables full mapping of free-space polarization states onto fiber vector modes, including the radially (TM) and azimuthally polarized (TE) modes. The setup requires few optical components and can yield mode purities as high as ∼30  dB. Additionally, just as a conventional fiber polarization controller creates arbitrary elliptical polarization states to counteract fiber birefringence and yield desired polarizations at the output of a single-mode fiber, q-plates disentangle degenerate state mixing effects between fiber OAM states to yield pure states, even after long-length fiber propagation. We thus demonstrate the ability to switch dynamically, potentially at ∼GHz rates, between OAM modes, or create desired linear combinations of them. We envision applications in fiber-based lasers employing vector or OAM mode outputs, as well as communications networking schemes exploiting spatial modes for higher dimensional encoding.
Controlled Growth of Pt Nanowires on Carbon Nanospheres and Their Enhanced Performance as Electrocatalysts in PEM Fuel Cells (2008)

Single-crystal Pt nanowires are directly grown on carbon nanospheres via a simple chemical route, at room temperature in aqueous solution. The growth density and length of Pt nanowires on the carbon support can be easily modulated. Of interest for PEM fuel cell application, such Pt nanowire/C composites show enhanced catalytic activity for the oxygen reduction reaction compared with a state-of-the-art Pt/C catalyst made of Pt nanoparticles.

Measurements of leaf water content using terahertz radiation (1999)

A novel technique for the noninvasive continuous measurement of leaf water content is presented. The technique is based on transmission measurements of terahertz radiation with a null-balance quasi-optical transmissometer operating at 94 GHz. A model for the propagation of terahertz radiation through leaves is presented. This, in conjunction with leaf thickness information determined separately, may be used to quantitatively relate transmittance measurements to leaf water content. Measurements using a dispersive Fourier transform spectrometer in the range of 100 GHz-500 GHz using Phormium tenax and Fatsia japonica leaves are also reported.
p38 Mitogen-Activated Protein Kinase-Dependent Hyperinduction of Tumor Necrosis Factor Alpha Expression in Response to Avian Influenza Virus H5N1 (2005)

Avian influenza A virus subtype H5N1 can infect humans to cause a severe viral pneumonia with mortality rates of more than 30%. The biological basis for this unusual disease severity is not fully understood. We previously demonstrated that in contrast to human influenza A virus subtypes including H1N1 or H3N2, the H5N1 virus associated with the "bird flu" outbreak in Hong Kong in 1997 (H5N1/97) hyperinduces proinflammatory cytokines, including tumor necrosis factor alpha (TNF-alpha), in primary human macrophages in vitro. To delineate the molecular mechanisms involved, we analyzed the role of transcription factor NF-kappaB and cellular kinases in TNF-alpha dysregulation. H5N1 and H1N1 viruses did not differ in the activation of NF-kappaB or degradation of IkappaB-alpha in human macrophages. However, we demonstrated that unlike H1N1 virus, H5N1/97 strongly activates mitogen-activated protein kinase (MAPK), including p38 MAPK and extracellular signal-regulated kinases 1 and 2. Specific inhibitors of p38 MAPK significantly reduced the H5N1/97-induced TNF-alpha expression in macrophages. Taken together, our findings suggest that H5N1/97-mediated hyperinduction of cytokines involves the p38 MAPK signaling pathway. These results may provide insights into the pathogenesis of H5N1 disease and rationales for the development of novel therapeutic strategies.
A novel circulating current suppressing method of modular multilevel converter (2014)

In this paper, a novel circulating current suppressing method of modular multilevel converter (MMC) is proposed. The circulating current is caused by the difference between the dc bus voltage and the sum voltage of upper arm and lower arm. When using actual value of sub-module capacitor voltage to generate switching function, the sum voltage of upper arm and lower arm is constantly equal to the dc bus. So the circulating current is zero. But the voltages of sub-modules in one phase are not able to balance. So circulating current must to be injected to balance the sub-modules voltages. But the amplitude of injected circulating current is very smaller. Simulation results on a MMC based on three-phase inverter show validity of the proposed method.

The Humanities in Deconstruction: Raising the Question of the Post-colonial University (2007)

Derrida is, perhaps, the foremost philosopher of the humanities and of its place in the university. Over the long period of his career he has been concerned with the fate, status, place and contribution of the humanities. Through his deconstructive readings and writings he has done much not only to reinvent the Western tradition by attending closely to those texts which constitute it but also he has redefined its procedures and protocols, questioning and commenting upon the relationship between commentary and interpretation, the practice of quotation, the delimitation of a work and its singularity, its signature, and its context - the whole form of life of literary culture, together with textual practices and conventions that shape it. From his very early work he has occupied a marginal in-between space - simultaneously, textual, literary, philosophical, and political - a space that permitted him a freedom to question, to speculate and to draw new limits to 'humanitas'. Derrida has demonstrated his power to reconceptualise and to reimagine the humanities in the space of the contemporary university. This paper discusses Derrida's tasks for the new humanities (Trifonas & Peters, 2005).
International Law: Recognition of Soviet Russia: Extraterritorial Effect of Decrees of Confiscation and Nationalization (1936)

The Moscow Fire Insurance Company, the Northern Insurance Company of Moscow, and the First Russian Insurance Company were incorporated in Russia under the Czarist regime, and given authority to do business in New York. Deposits were made in New York for the benefit of policy holders and creditors in this country. Subsequent to the revolution in Russia and the Soviet decrees nationalizing all Russian corporations and confiscating without compensation such corporations' assets in Russia and abroad, these deposits were turned over to the New York State Insurance Commissioner for liquidation. Large sums remained after domestic claims were satisfied and the court ordered them turned over to the defendant institutions to be held in trust for whomsoever should be entitled thereto. The old boards of directors and shareholders in the old corporations instituted actions in the New York courts to have this money turned over to them. In November of 1933 the United States recognized the Soviet Government and an assignment was made by the Soviet Government to the United States Government of all claims which the Soviet Government had to property in the United States at that time. The United States Government brought suit in the Federal District Court, Eastern District of New York, claiming the funds in question on the ground that the Soviet decrees of confiscation gave the Soviet Government title to the funds and that the claims to them had been assigned to the United States Government. The district court decided against the claim of the United States on the ground that the Soviet decrees were against the public policy of the United States and were ineffective to pass title to this property, and also that the purported assignment did not include these funds. On certiorari to the United States Supreme Court, held, because the New York courts had retained control and jurisdiction over the funds and its proceedings were not terminated, and the suit of the United States was for the specific funds and not in personam merely, the United States must bring its suit in the New York courts. United States v. Bank of New York & Trust Co., 296 U.S. 463, 56 S. Ct. 343 (1936).
Recent discovery and development of endothelin receptor antagonists (2000)

Endothelin (ET) receptor antagonists, in particular ETA selective or ETA/ETB balanced antagonists, represent a new therapeutic area for serious diseases such as congestive heart failure (CHF) and pulmonary hypertension. Endothelin antagonists have profound effects on the pulmonary vasculature and the right heart whereas ACE inhibitors primarily affect the peripheral vessel and the left heart. Therefore, combination of endothelin antagonists and ACE inhibitors may be particularly useful in chronic heart failure. Pulmonary hypertension represents another unmet medical need where endothelin antagonists, especially orally-active compounds, show great promise. The importance of this field is evidenced by the number of compounds in clinical trials and by the number of patents filed in recent years. Between January 1997 and April 2000, there are 139 endothelin patents of which 128 are concerned with endothelin receptor antagonists and 11 with endothelin converting enzyme inhibitors. Of the 128 patents, 93 are about new chemical structures, 16 process, 4 formulation, 14 new use or combination therapy and 1 natural product. This article focuses on the 93 novel composition of matter patents in the area of endothelin receptor antagonists.
