On skein relations in class S theories

Loop operators of a class S theory arise from networks on the corresponding Riemann surface, and their operator product expansions are given in terms of the skein relations, that we describe in detail in the case of class S theories of type A. As two applications, we explicitly determine networks corresponding to dyonic loops of $N=4$ $SU(3)$ super Yang-Mills, and compute the superconformal index of a nontrivial network operator of the $T_3$ theory.Comment: 44 pages, v2 add a few references and little modification in sec.

D∗D^{\ast} polarization vs. RD(∗)R_{D^{(\ast)}} anomalies in the leptoquark models

Polarization measurements in $\bar{B} \to D^{(\ast)} \tau \overline{\nu}$ are useful to check consistency in new physics explanations for the $R_{D}$ and $R_{D^{\ast}}$ anomalies. In this paper, we investigate the $D^{\ast}$ and $\tau$ polarizations and focus on the new physics contributions to the fraction of a longitudinal $D^{\ast}$ polarization ($F_{L}^{D^{\ast}}$), which is recently measured by the Belle collaboration $F_{L}^{D^{\ast}} = 0.60 \pm 0.09$, in model-independent manner and in each single leptoquark model (${\rm R}_2$, ${\rm S}_1$ and ${\rm U}_1$) that can naturally explain the $R_{D^{(\ast)}}$ anomalies. It is found that $\mathcal{B}(B_c^{+} \to \tau^{+} \nu)$ severely restricts deviation from the Standard Model (SM) prediction of $F_{L, \textrm{SM}}^{D^{\ast}} = 0.46 \pm 0.04$ in the leptoquark models: [0.43, 0.44], [0.42, 0.48], and [0.43, 0.47] are predicted as a range of $F_{L}^{D^{\ast}}$ for the ${\rm R}_2$, ${\rm S}_1$, and ${\rm U}_1$ leptoquark models, respectively, where the current data of $R_{D^{(\ast)}}$ is satisfied at $1\,\sigma$ level. It is also shown that the $\tau$ polarization observables can much deviate from the SM predictions. The Belle II experiment, therefore, can check such correlations between $R_{D^{(\ast)}}$ and the polarization observables, and discriminate among the leptoquark models.Comment: 24 pages, 3 figures, 1 table; references added, version published in JHE

Unstable pseudo-isotopies of spherical 3-manifolds

In our previous works, we constructed diffeomorphisms of compact 4-manifolds $X$ by surgeries on theta-graphs embedded in $X$. In this paper, we consider the case $X=M\times I$, where $M$ is a spherical 3-manifold. For some of such $X$, we compute lower bounds of the ranks of the abelian groups $\pi_0\mathrm{Diff}(X,\partial)$. We study the behavior of the elements constructed by theta-graph surgery under the suspension functor in stable pseudo-isotopy theory, and their triviality in the space of block diffeomorphisms.Comment: 17 pages.

Properties of Concrete Using Treated Low-Class Recycled Coarse Aggregate and Blast Furnace Slag Sand

Since high quality natural aggregates are becoming scarce, it is important that industrial recycled products and by-products are used as aggregates for concrete. In Japan, the use of recycled aggregate (RG) is encouraged. Since, strength and durability of recycled aggregate concrete is lower than that of normal aggregate concrete, the use of recycled aggregate has not been significant. In order to improve physical properties of concrete using recycled coarse aggregate, blast furnace slag sand has been proposed. Recently, blast furnace slag sand is expected to improve durability, freezing, and thawing damage of concrete in Japan. Properties of fresh and hardened concrete bleeding, compressive strength, and resistance to freezing and thawing which are caused by the rapid freezing and thawing test using liquid nitrogen is a high loader than the JIS A 1148 A method that were investigated. As a result, concrete using treated low-class recycled coarse aggregate and 50% or 30% replacement of crushed sand with blast furnace slag sand showed the best results, in terms of bleeding, resistance to freezing and thawing

Toward Introduction of Immunity-based Model to Continuous Behavior-based User Authentication on Smart Phone

AbstractSmart phone stores a lot of important private information, so that user authentication is increasingly necessary to prevent attacks by illegal users who are not the owner of the smart phone. Password authentication or biometrics can be generally applied only on login. After the authentication is passed, not only the legal owner but also illegal users freely use the smart phone. Therefore we are trying to develop a behavior-based user authentication system to continuously check the user activities after login. The developing system can extract many operational and behavioral features characteristic of user by multiple sensors; for example, touch screen, accelerometer, microphone, and GPS sensor. And then it can combine the authentication results from the multiple sensors because a single sensor may produce poor authentication accuracy. In this paper, we report the ongoing results of our system, that is, the experimental results from user authentication using touch operational features, and some features extracted from accelerometer. We also discuss the introduction of immunity-based model to our system to integrate the authentication results from the multiple sensors

β_2-インデグランド ニ カイゴウスル シンキ ヒト GPI アンカー タンパクシツ GPI-80 ニタイスル タンクローン コウタイ ワ ヒト タンキュウ ノ macropinocytosis オ センタクテキ ニ ゾウキョウ スル

We have shown previously that neutrophils and small population of human monocytes have a glycosylphosphatidylinositol (GPI) -anchored protein, GPI-80 on their surface. In a study of neutrophils, we reported that GPI-80 regulates the adherence and migration. In this study, we examined the functions of GPI-80 in monocytes. Treatment of monocytes with monoclonal antibody (mAb) to GPI-80 enhanced pinocytosis of fluorescein isothiocyanate (FITC)-labeled dextran but not that of lucifer yellow and low-density lipoprotein. This treatment neither changed phagocytosis, adherence nor reactive oxygen production of monocytes. These results suggest that GPI-80 modulates fluid phase macropinocytosis of high molecular weight molecules, but not that of low molecular weight ones, clathrin-dependent pinocytosis, phagocytosis, adherence and reactive oxygen production. Treatment of neutrophils with mAbs to GPI-80 did not change macropinocytosis of FITC-labeled dextran, suggesting that the functions of GPI-80 on macropinocytosis of high molecular weight molecules are different between neutrophils and monocytes. This study, first reported GPI-80 function on monocytes, implies that GPI-80 may be one of the molecules associated with macropinocytosis on monocytes.　Key words: macropinocytosis, monocytes, GPI -anchored protei

Protogenin mediates cell adhesion for ingression and re-epithelialization of paraxial mesodermal cells

AbstractIn the avian embryo, precursor cells of the paraxial mesoderm that reside in the epiblast ingress through the primitive streak and migrate bilaterally in an anterolateral direction. Herein, we report on the roles of Protogenin (PRTG), an immunoglobulin superfamily protein expressed on the surface of the ingressing and migrating cells that give rise to the paraxial mesoderm, in paraxial mesoderm development. An aggregation assay using L-cells showed that PRTG mediates homophilic cell adhesion. Overexpression of PRTG in the presumptive paraxial mesoderm delayed mesodermal cell migration due to augmented adhesiveness. In contrast, siRNA knockdown of PRTG impaired successive ingression of epiblast cells and disorganized the epithelial structure of the somites. These results suggest that PRTG mediates cell adhesion to regulate continuous ingression of cells giving rise to the paraxial mesodermal lineage, as well as tissue integrity

Co-emergence of Institutional Innovation Navigates the New Normal in Growing Economies

Increasing fear of the global simultaneous stagnation derived from the Euro-crisis together with the New Normal in growing economies reveals the limit of individual strength leading to the significance of fusion with global best practices. Dramatic advancement of the Internet has enabled consumers in any nation to choose and learn from world’s strongest suppliers. Both trends inevitably necessitate co-emergence of institutional innovation between suppliers and consumers for sustainability. On the basis of an empirical analysis comparing institutional systems in 100 nations, this paper demonstrates the significance of this co-emergence thereby navigating the New Normal in growing economies
