description: Direct numerical simulations of the Taylor-Couette (TC) problem, the flow between two coaxial and independently rotating cylinders, have been performed. The study focuses on TC flow with mild curvature (small gap) with a radius ratio of $η=r_i/r_o=0.909$, an aspect ratio of $Γ=L/d=2π/3$, and a stationary outer cylinder. Three inner cylinder Reynolds of $1\cdot10^5$, $2\cdot10^5$ and $3\cdot 10^5$ were simulated, corresponding to frictional Reynolds numbers between $Re_τ\approx 1400$ and $Re_τ\approx 4000$. An additional case with a large gap, $η=0.5$ and driving of $Re=2\cdot10^5$ was also performed. Small-gap TC was found to be dominated by spatially-fixed large-scale structures, known as Taylor rolls (TRs). TRs are attached to the boundary layer, and are active, i.e. they transport angular velocity through Reynolds stresses. An additional simulation with inner cylinder Reynolds number of $Re=1\cdot10^5$ and fixed outer cylinder with an externally imposed axial flow of comparable strength as the wind of the TRs was also conducted. The axial flow was found to convect the TRs without any weakening effect. For small-gap TC, evidence for the existence of logarithmic velocity fluctuations, and of an overlap layer, in which the velocity fluctuations collapse in outer units, was found. Profiles consistent with a logarithmic dependence were also found for the angular velocity in large-gap TC, albeit in a very reduced range of scales. Finally, the behaviour of both small- and large-gap TC was compared to other canonical flows. Small-gap TC has similar behaviour in the near-wall region to other canonical flows, while large-gap TC displays very different behaviour.

description: We present a simple novel construction of recursion operators for integrable multidimensional dispersionless systems that admit a Lax pair whose operators are linear in the spectral parameter and do not involve the derivatives with respect to the latter. New examples of recursion operators obtained using our technique include {\em inter alia} those for the general heavenly equation, which describes a class of anti-self-dual solutions of the vacuum Einstein equations, and a six-dimensional equation resulting from a system of Ferapontov and Khusnutdinova.

Group A streptococcal peptidoglycan-polysaccharide inhibits phagocytic activity of human polymorphonuclear leukocytes.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1984

description: Injection of sterile aqueous preparations of the peptidoglycan-polysaccharide of group A streptococci (PG-APS) produces chronic inflammation in several animal models. Chronic bacterial infection may be involved in some aspects of the pathogenesis of inflammation associated with the accumulation of PG-APS. Accordingly, the effect of PG-APS on human neutrophil (polymorphonuclear leukocyte [PMN]) bactericidal activity was studied with the supposition that this interaction may contribute to the inflammation observed. Concentrations of PG-APS greater than 10 micrograms/ml inhibited the ability of PMNs to kill Staphylococcus aureus. This inhibition was not due to a cytotoxic effect of PG-APS on PMNs, nor did PG-APS inhibit PMN metabolism required for the formation of microbicidal oxygen reduction products. PG-APS concentrations of 10 micrograms/ml or greater in the presence of 10% normal serum inhibited the attachment of bacteria to PMNs by 49% as compared with control cell populations. The concentrations of PG-APS required to inhibit uptake of Staphylococcus aureus were identical to those required for inhibition of PMN bactericidal activity. This inhibition did not occur in the presence of serum-free medium or medium with sera that had been heated to inactivate complement. These results show that PG-APS interacts with serum to inhibit PMN-mediated killing of S. aureus, most probably by interfering with bacterial uptake.

description: We study a multiplicative transient price impact model for an illiquid financial market, where trading causes price impact which is multiplicative in relation to the current price, transient over time with finite rate of resilience, and non-linear in the order size. We construct explicit solutions for the optimal control and the value function of singular optimal control problems to maximize expected discounted proceeds from liquidating a given asset position. A free boundary problem, describing the optimal control, is solved for two variants of the problem where admissible controls are monotone or of bounded variation.

To the authors' knowledge, this is the first such classification result for an algebra of dimension $> 1$. In the course of this study, we classify also all maximal $\textbf{k}$-subalgebras of $\textbf{k}[t, y]$ that contain a coordinate. Furthermore, we give examples of maximal $\textbf{k}$-subalgebras of $\textbf{k}[t, y]$ that do not contain a coordinate.

description: Given a complete noncompact Riemannian manifold $N^n$, we investigate whether the set of bounded Sobolev maps $(W^{1, p} \cap L^\infty) (Q^m; N^n)$ on the cube $Q^m$ is strongly dense in the Sobolev space $W^{1, p} (Q^m; N^n)$ for $1 \le p \le m$. The density always holds when $p$ is not an integer. When $p$ is an integer, the density can fail, and we prove that a quantitative trimming property is equivalent with the density. This new condition is ensured for example by a uniform Lipschitz geometry of $N^n$. As a byproduct, we give necessary and sufficient conditions for the strong density of the set of smooth maps $C^\infty (\overline{Q^m}; N^n)$ in $W^{1, p} (Q^m; N^n)$.

description: We introduce a non-commutative generalization of the Gross-Pitaevskii equation for one-dimensional quantum gasses and quantum liquids. This generalization is obtained by applying the time-dependent variational principle to the variational manifold of continuous matrix product states. This allows for a full quantum description of many body system ---including entanglement and correlations--- and thus extends significantly beyond the usual mean-field description of the Gross-Pitaevskii equation, which is known to fail for (quasi) one-dimensional systems. By linearizing around a stationary solution, we furthermore derive an associated generalization of the Bogoliubov -- de Gennes equations. This framework is applied to compute the steady state response amplitude to a periodic perturbation of the potential.

description: A new estimation of the isotropic diffuse gamma-ray background (IGRB) observed by the Large Area Telescope (LAT) on board the Fermi Gamma-ray Space Telescope (Fermi) has been presented for 50 months of data, in the energy range 100 MeV-820 GeV and for different modelings of the Galactic foreground. We attempt here the interpretation of the Fermi-LAT IGRB data in terms of the gamma-ray unresolved emission from different extragalactic populations. We find very good fits to the experimental IGRB, obtained with theoretical predictions for the emission from active galactic nuclei and star-forming galaxies. In addition, we probe a possible emission coming from the annihilation of weakly interacting dark matter (DM) particles in the halo of our Galaxy. We set stringent limits on its annihilation cross section into gamma rays, which are about the thermal relic value for a wide range of DM masses. We also identify regions in the DM mass and annihilation cross section parameter space which can significantly improve the fit to the IGRB data. Our analysis is conducted within the different IGRB data sets obtained from different models for the Galactic emission, which is shown to add a significant ambiguity on the IGRB interpretation.

description: A hybridoma derived from a mouse immunized with gonococcal outer membranes produced an antibody, designated H.8, that bound to all strains of Neisseria gonorrhoeae and N. meningitidis tested, and to N. lactamica and N. cinerea, but only rarely to other nonpathogenic Neisseria species. Studies with the gonococcal strain used in production of the antibody showed that the antibody bound to a surface-exposed, protease-sensitive, and heat-modifiable outer membrane antigen that we believe is distinct from previously described gonococcal outer membrane proteins.

description: Five mouse ascitic fluids (MAFs) containing monoclonal antibody to Rickettsia rickettsii were produced from three original fusions by murine hybridoma technology. The five MAFs were fractionated and purified; each contained monoclonal antibody of the immunoglobulin G2a subclass. Each monoclonal antibody-containing MAF was titrated by indirect immunofluorescence against three R. rickettsii isolates from humans and four other spotted fever group rickettsiae. Each MAF was also titrated in the complement fixation, latex agglutination, microagglutination, and indirect hemagglutination tests. Two of the MAFs were examined for their ability to prevent fever and rickettsemia in susceptible guinea pigs after a 1:100 dilution of each was mixed with viable R. rickettsii, and all five MAFs were titrated in the mouse toxicity phenomenon assay. All MAFs had high indirect immunofluorescence titers to the three strains of R. rickettsii (1:200,000 to 1:800,000), reduced indirect immunofluorescence titers to R. montana, and were nonreactive with R. akari, R. sibirica, and R. conorii. Each MAF was able to fix complement in the presence of spotted fever group antigen reagent and agglutinate a suspension of purified R. rickettsii, and each was negative in both the latex agglutination and the indirect hemagglutination tests. The two MAFs which were tested proved to be capable of preventing rickettsemia and death in guinea pigs, and each MAF was able to prevent death in mice at dilutions ranging from 1:40 to 1:80.

description: We propose a simple construction of the solution to the continuum parabolic Anderson model on $\mathbf{R}^2$ which does not rely on any elaborate arguments and makes extensive use of the linearity of the equation. A logarithmic renormalisation is required to counterbalance the divergent product appearing in the equation. Furthermore, we use time-dependent weights in our spaces of distributions in order to construct the solution on the unbounded space $\mathbf{R}^2$.

Cellular and extracellular protein antigens of Treponema pallidum synthesized during in vitro incubation of freshly extracted organisms.

description: A new medium that permits radiolabeling of freshly extracted cells of Treponema pallidum with [35S]methionine very efficiently has been devised. Although treponemes were not purified free of contaminating rabbit tissue, label was incorporated exclusively into treponemal protein in a linear manner for at least the first 16 h of in vitro incubation. Throughout this period, virtually a full complement of treponemal proteins was synthesized, based on a sodium dodecyl sulfate-polyacrylamide gel electrophoresis comparison of the radiolabeled protein profile with the Coomassie blue-stained profile of gradient-purified treponemes. The radiolabeled protein profiles obtained with three pathogenic strains were very similar but not identical. Using solubilized treponemal extracts and a sensitive radioimmunoprecipitation procedure, we identified the protein antigens of T. pallidum that were recognized by immunoglobulin G antibodies in various rabbit and human syphilitic sera. A simple fractionation procedure has been used to separate soluble and membrane-bound treponemal proteins. A number of the membrane proteins are exposed on the cell surface, since intact radiolabeled treponemes bound antibodies directed against these proteins. In addition, a unique class of low-molecular-weight extracellular treponemal proteins has been identified. The cell surface-exposed proteins were among the earliest proteins recognized by immunoglobulin G antibodies after experimental infection of rabbits with T. pallidum.

description: Micro-location is the process of locating any entity with high accuracy (possibly in centimeters), while geofencing is the process of creating a virtual fence around a so-called Point of Interest (PoI). In this paper, we present an insight into various micro-location enabling technologies and services. We also discuss how these can accelerate the incorporation of Internet of Things (IoT) in smart buildings. We argue that micro-location based location-aware solutions can play a significant role in facilitating the tenants of an IoT equipped smart building. Also, such advanced technologies will enable the smart building control system through minimal actions performed by the tenants. We also highlight the existing and envisioned services to be provided by using micro-location enabling technologies. We describe the challenges and propose some potential solutions such that micro-location enabling technologies and services are thoroughly integrated with IoT equipped smart building.

Recently this conjecture has been proved for $n=5$ and disproved for $n\ge 7$, leaving the case $n=6$ open. We make a step toward proving the conjecture for $n=6$. We show that if $A$ is a $6\times 6$ completely positive matrix that is orthogonal to an exceptional extremal copositive matrix, then the cp-rank of $A$ is at most $9$.

description: We propose a quantum voting system, in the spirit of quantum games such as the quantum Prisoner's Dilemma. Our scheme enables a constitution to violate a quantum analog of Arrow's Impossibility Theorem. Arrow's Theorem is a claim proved deductively in economics: Every (classical) constitution endowed with three innocuous-seeming properties is a dictatorship. We construct quantum analogs of constitutions, of the properties, and of Arrow's Theorem. A quantum version of majority rule, we show, violates this Quantum Arrow Conjecture. Our voting system allows for tactical-voting strategies reliant on entanglement, interference, and superpositions. This contribution to quantum game theory helps elucidate how quantum phenomena can be harnessed for strategic advantage.

description: By a conformal string in Euclidean space is meant a closed critical curve with non-constant conformal curvatures of the conformal arclength functional. We prove that (1) the set of conformal classes of conformal strings is in 1-1 correspondence with the rational points of the complex domain $\{q\in \mathbb{C} \,:\, 1/2 < \mathrm{Re}\, q < 1/\sqrt{2},\,\, \mathrm{Im}\, q > 0,\,\, |q| < 1/\sqrt{2}\}$ and (2) any conformal class has a model conformal string, called symmetrical configuration, which is determined by three phenomenological invariants: the order of its symmetry group and its linking numbers with the two conformal circles representing the rotational axes of the symmetry group. This amounts to the quantization of closed trajectories of the contact dynamical system associated to the conformal arclength functional via Griffiths' formalism of the calculus of variations.

description: We show that a vector matter-wave soliton in Bose-Einstein condensate loaded into an optical lattice can escape from a trap formed by a parabolic potential, resembling a Hawking emission. The particle-antiparticle pair is emulated by a low-amplitude bright-bright soliton in two-component Bose-Einstein condensate with effective masses of opposite signs. It is shown that the parabolic potential leads to a spatial separation of BEC components. One component with chemical potential in a semi-infinite gap exerts periodical oscillations, while the other BEC component, with negative effective mass, escapes from the trap. The mechanism of atoms transfer from one BEC component to another by spatially periodic linear coupling term is discussed.

description: Although applications of additive manufacturing (AM) have been significantly increased in recent years, its broad application in several industries is still under progress. AM also known as three-dimensional (3D) printing is layer by layer manufacturing process which can be used for fabrication of geometrically complex customized functional end-use products. Since AM processing parameters have significant effects on the performance of the printed parts, it is necessary to tune these parameters which is a difficult task. Today, different artificial intelligence techniques have been utilized to optimize AM parameters and predict mechanical behavior of 3D-printed components. In the present study, applications of machine learning (ML) in prediction of structural performance and fracture of additively manufactured components has been presented. This study first outlines an overview of ML and then summarizes its applications in AM. The main part of this review, focuses on applications of ML in prediction of mechanical behavior and fracture of 3Dprinted parts. To this aim, previous research works which investigated application of ML in characterization of polymeric and metallic 3D-printed parts have been reviewed and discussed. Moreover, the review and analysis indicate limitations, challenges, and perspectives for industrial applications of ML in the field of AM. Considering advantages of ML increase in applications of ML in optimization of 3D printing parameters, prediction of mechanical performance, and evaluation of 3D-printed products is expected.

description: Accurate modeling of the dynamic stall remains a challenge for the design and construction of turbine blades and helicopter rotors. At the same time, wind turbines, for instance, are becoming steadily larger, further increasing the demands on their structure and necessitating even more detailed modeling of the forces at hand. The primarily used (semi-)empirical models today have a long research history and are invariably based on phase-averaged data from oscillating blade pitch experiments. However, much potential for more accurate modeling of uncertainties and force peaks is wasted here, since averaging blurs many features of the response signals. Even computational fluid dynamics can help little in this regard, since the Reynolds-averaged Navier–Stokes equations used in practice cannot account for cycle variations, and scale-resolving models require extremely large amounts of computational resources. This paper presents an approach for a fully stochastic machine learning model that can nevertheless simulate these critical properties. Aerodynamic coefficients are compared with experimental data for different test cases. It is shown that synthetic force profiles which cannot be distinguished from the experimental data visually and are very close to them in the frequency spectrum can be generated. Additionally, attention is drawn to the difficulty of evaluating such a model, as traditional error metrics are of little use. A combination of dynamic time warping and the Earth mover's distance provides a robust solution for this problem.

description: Fabrication based on additive manufacturing (AM) process from a three-dimensional (3D) model has received significant attention in the past few years. Although 3D printing was introduced for production of prototypes, it has been currently used for fabrication of end-use products. Therefore, the mechanical behavior and strength of additively manufactured parts has become of significant importance. 3D printing has been affected by different parameters during preparation, printing, and post-printing processes, which have influence on quality and behavior of the additively manufactured components. This paper discusses the effects of two printing parameters on the mechanical behavior of additively manufactured components. In detail, polylactic acid material was used to print test coupons based on fused deposition modeling process. The specimens with five different raster orientations were printed with different printing speeds. Later, a series of tensile tests was performed under static loading conditions. Based on the results, strength and stiffness of the examined specimens have been determined. Moreover, dependency of the strength and elastic modulus of 3D-printed parts on the raster orientation has been documented. In the current study, fractured specimens were visually investigated by a free-angle observation system. The experimental findings can be used for the development of computational models and next design of structural components.

description: Distinct multiple antigenic determinants of the attachment protein of Mycoplasma pneumoniae have been identified by limited proteolytic cleavage, using specific monoclonal antibodies. Western blots prepared from the gels containing the cleaved fragments were probed with antiserum against M. pneumoniae or monoclonal antibodies. Five distinct bands with intact antigenic determinants were detected by the antiserum, of which two bands were each reactable with two monoclonal antibodies. A sequential binding assay suggested that these monoclonal antibodies recognized different antigenic sites of each band. These results demonstrate the existence of multiple antigenic sites on the attachment protein and describe procedures that should prove useful for identifying those antigenic sites critical to the specific attachment of M. pneumoniae.

description: IIt is known that a statistically significant treatment may not be clinically significant. A quantity that can be used to assess clinical significance is called the minimum clinically important difference (MCID), and inference on the MCID is an important and challenging problem. Modeling for the purpose of inference on the MCID is non-trivial, and concerns about bias from a misspecified parametric model or inefficiency from a nonparametric model motivate an alternative approach to balance robustness and efficiency. In particular, a recently proposed representation of the MCID as the minimizer of a suitable risk function makes it possible to construct a Gibbs posterior distribution for the MCID without specifying a model. We establish the posterior convergence rate and show, numerically, that an appropriately scaled version of this Gibbs posterior yields interval estimates for the MCID which are both valid and efficient even for relatively small sample sizes.

description: We propose a refinement of the Betti numbers and of the homology with coefficients in a field of a compact ANR in the presence of a continuous real valued function. The refinement of Betti numbers consists of finite configurations of points with multiplicities in the complex plane whose total cardinality are the Betti numbers and the refinement of homology consists of configurations of vector spaces indexed by points in complex plane, with the same support as the first, whose direct sum is isomorphic to the homology. When the homology is equipped with a scalar product these vector spaces are canonically realized as mutually orthogonal subspaces of the homology. The assignments above are in analogy with the collections of eigenvalues and generalized eigenspaces of a linear map in a finite dimensional complex vector space. A number of remarkable properties of the above configurations are discussed.

description: Humans are the sole reservoir of Neisseria gonorrhoeae, an organism which undergoes a marked increase in metabolic rate after exposure to a low-molecular-weight, heat-stable component(s) of human serum. Further studies on the effect of serum on gonococcal metabolism were undertaken. Gonococcal broth (GCB) is commonly used for in vitro cultivation of gonococci. Gonococci suspended in GCB plus 10% serum exhibited oxygen consumption rates of 139% (P less than 0.01) and 456% (P less than 0.01) of those suspended in GCB or Hanks balanced salt solution, respectively. A twofold increase in growth rate also resulted from the addition of 10% serum to GCB. Gonococcal 14C-labeled adenine incorporation increased threefold with 10% serum supplementation of Hanks balanced salt solution. Dialysis of serum in 1,000-molecular-weight exclusion tubing removed the stimulatory factor(s). Neither correction of anion-cation concentrations altered by dialysis nor addition of substances of known importance to the metabolism of gonococci (i.e., lactate, pyruvate, cysteine, ATP, AMP, NADPH, amino acids, malate, and glutathione) to dialyzed serum reconstituted stimulatory capacity. The effect of serum on gonococcal glucose-catabolic pathways was measured by modified radiospirometry. An apparent threefold increase in Entner-Doudoroff and pentose phosphate pathway activities was induced by 10% serum, as was the increased shunting of glucose-derived glyceraldehyde-3-phosphate into these pathways. These metabolic changes did not allow specific identification of the serum stimulatory factor(s). Acetate, the major by-product of gonococcal glucose catabolism, inhibited gonococcal oxygen consumption as previously reported. A high-molecular-weight serum component, probably albumin, reversed acetate-mediated inhibition of gonococcal oxygen consumption, identifying a second mechanism by which serum increases gonococcal metabolism. These results suggest that supplementation of growth media with serum should be considered to provide N. gonorrhoeae with conditions more consistent with its normal environment.

description: We demonstrate that the Weihrauch lattice can be used to classify the uniform computational content of computability-theoretic properties as well as the computational content of theorems in one common setting. The properties that we study include diagonal non-computability, hyperimmunity, complete consistent extensions of Peano arithmetic, 1-genericity, Martin-Löf randomness, and cohesiveness. The theorems that we include in our case study are the low basis theorem of Jockusch and Soare, the Kleene-Post theorem, and Friedberg's jump inversion theorem. It turns out that all the aforementioned properties and many theorems in computability theory, including all theorems that claim the existence of some Turing degree, have very little uniform computational content: they are located outside of the upper cone of binary choice (also known as LLPO); we call problems with this property indiscriminative. Since practically all theorems from classical analysis whose computational content has been classified are discriminative, our observation could yield an explanation for why theorems and results in computability theory typically have very few direct consequences in other disciplines such as analysis. A notable exception in our case study is the low basis theorem which is discriminative. This is perhaps why it is considered to be one of the most applicable theorems in computability theory. In some cases a bridge between the indiscriminative world and the discriminative world of classical mathematics can be established via a suitable residual operation and we demonstrate this in the case of the cohesiveness problem and the problem of consistent complete extensions of Peano arithmetic. Both turn out to be the quotient of two discriminative problems.

Identification and characterization of the protein antigens of Leptospira interrogans serovar hardjo.

description: We radiolabeled Leptospira proteins with [35S]methionine. Solubilized extracts of radiolabeled L. interrogans serovar hardjo strain hardjoprajitno were analyzed by one-dimensional sodium dodecyl sulfate-polyacrylamide gel electrophoresis and fluorography. We compared the protein profile obtained in this manner to the protein profiles of various [35S]methionine-labeled Leptospira spp. The profiles of the pathogenic L. interrogans strains were very similar but not identical and exhibited no obvious relationship to those of the two nonpathogenic species. We used solubilized, radiolabeled hardjoprajitno extracts and a sensitive radioimmunoprecipitation procedure to identify protein antigens recognized by immunoglobulin G antibodies present in various rabbit anti-hardjo sera. Homologous hyperimmune rabbit serum efficiently precipitated a large subset of proteins, the majority of which were between 30,000 and 66,500 daltons. Radioimmunoprecipitations with sera prepared against each of four recent hardjo isolates cultured from infected cattle produced similar results. Immunoprecipitations done with various radiolabeled Leptospira extracts and anti-hardjoprajitno serum demonstrated that the pathogenic leptospires possessed a number of cross-reactive major and minor protein antigens. By cell fractionation procedures, we found that most of the major protein antigens were present in the outer envelope. These proteins were exposed on the leptospiral cell surface because intact radiolabeled leptospires bound antibodies directed against them.

description: In this paper we consider the equivariant 2+1 dimensional Einstein-wave map system and show that if the target satisfies the so called Grillakis condition, then global existence holds. In view of the fact that the 3+1 vacuum Einstein equations with a spacelike translational Killing field reduce to a 2+1 dimensional Einstein-wave map system with target the hyperbolic plane, which in particular satisfies the Grillakis condition, this work proves global existence for the equivariant class of such spacetimes.

Influence of estrogen on host resistance: increased susceptibility of mice to Listeria monocytogenes correlates with depressed production of interleukin 2.

description: Mice given pharmacological levels of the synthetic estrogen diethylstilbestrol demonstrated a marked increase in susceptibility to infection with Listeria monocytogenes. Experiments were performed in an effort to determine the mechanism(s) by which estrogen treatment increases the susceptibility of mice to L. monocytogenes infection. Estrogen exposure depressed the in vivo proliferative response of splenic lymphocytes to L. monocytogenes, which correlated with the decreased in vitro response of these cells to phytohemagglutinin. Interleukin 2 (IL 2) production by splenic lymphocytes from estrogen-treated mice was decreased, although these cells were capable of proliferating normally in response to exogenous IL 2. Interleukin 1 production by peritoneal macrophages was not depressed by estrogen exposure. The number of bacteria observed in the spleens of estrogen-exposed mice challenged with L. monocytogenes was reduced by IL 2 administration. Thus, estrogens may decrease host resistance to L. monocytogenes by inhibiting IL 2 production and the subsequent proliferation of antigen-sensitized T lymphocytes required for recovery.
