    The double scaling limit of the multi-orientable tensor model

    Full text link
    In this paper we study the double scaling limit of the multi-orientable tensor model. We prove that, contrary to the case of matrix models but similarly to the case of invariant tensor models, the double scaling series are convergent. We resum the double scaling series of the two point function and of the leading singular part of the four point function. We discuss the behavior of the leading singular part of arbitrary correlation functions. We show that the contribution of the four point function and of all the higher point functions are enhanced in the double scaling limit. We finally show that all the correlation functions exhibit a singularity at the same critical value of the double scaling parameter which, combined with the convergence of the double scaling series, suggest the existence of a triple scaling limit

    Two-dimensional abelian BF theory in Lorenz gauge as a twisted N=(2,2) superconformal field theory

    Full text link
    We study the two-dimensional topological abelian BF theory in the Lorenz gauge and, surprisingly, we find that the gauged-fixed theory is a free type B twisted N=(2,2) superconformal theory with odd linear target space, with the ghost field c being the pullback of the linear holomorphic coordinate on the target. The BRST operator of the gauge-fixed theory equals the total Q of type B twisted theory. This unexpected identification of two different theories opens a way for nontrivial deformations of both of these theories.Comment: Ver. 2: a discussion of the relation of descent to AKSZ construction added. Ver. 3: section 2.5.2 (a toy example of Gromov-Witten invariant) corrected; section 2.5.1 expanded with comments on the BV generating function for the action of a vector fiel

    A New Tool for Discourse Analysis: The Vocabulary-Management Profile

    Get PDF
    Includes bibliographical references.A Turbo Pascal program is used to generate vocabulary management profiles (VMPs). The program counts the new vocabulary words introduced into a text over successive thirty-five-word intervals, and these numbers are then plotted at the midpoints of their intervals. The resulting VMPs show clearcut peaks and valleys that demarcate constituents in discourse. New episodes in narratives and new topics in essays show up as sharp rises preceded by deep valleys in the curve. This correlation between new vocabulary and new topics suggests that is plausible to interpret VMPs as information-management, as well as vocabulary-management, profiles for a discourse. The VMPs for passages from James Joyce and George Orwell show surprisingly regular alternations between new and repeated vocabulary,reflecting two competing principles that underlie the structure of all discourse--innovation and coherence

    Sources of Social Capital for Malawi People Living With HIV.

    Get PDF
    With one of the highest rates of poverty and HIV in the world, Malawi faith-based organizations (FBOs), non-governmental organizations (NGOs), and community-based organizations (CBOs) are expected to provide tangible and emotional support to people living with HIV (PLWH). Using Lin's social capital theoretical approach, we examine the perspective of PLWH regarding the adequacy of support responses. Forty-six rural Malawi HIV+ adults provided interviews that were recorded digitally, translated, and transcribed by Malawi research assistants. Atlas.ti was used to organize the data and to aid in the analytic process. Participants expressed disappointment in the lack of resources that could be accessed through the FBOs although their expectations may have been unrealistic. Outcomes from accessing and mobilizing the FBO network were negative in terms of stigmatization by FBO leaders and members, whereas outcomes related to CBOs and NGOs were generally positive in terms of empowerment through HIV information and attendance at support groups

    Closed loop fiber optic rotation sensor

    Get PDF
    An improved optical gyroscope is provided, of the type that passes two light components in opposite directions through an optic fiber coil, and which adds a small variable frequency to one of the light components to cancel the phase shift due to rotation of the coil. The amount of coil rotation from an initial orientation, is accurately determined by combining the two light components, one of which has a slightly increased frequency, to develop beats that each represent a predetermined angle of rotation. The direction of rotation is obtained by combining the two light components on a photodetector, intermittently phase shifting a single light component by 90 deg and comparing the direction of change of photodetector output (+ or -) caused by the 90 deg shift, with the slope (+ or -) of the photodetector output at about the same time, when there is a 90 deg shift

    The Vocabulary-Management Profile: Two Stories by William Faulkner

    Get PDF
    Includes bibliographical references.The Vocabulary-Management Profile (VMP) is a graph of the moving average of the number of new vocabulary words introduced over successive intervals of text. Peaks and valleys on the VMP correlate closely with narrative structure: new episodes, new settings, new characters are signaled by an increase in new vocabulary, and hence by upturns on the curve. Conversely, downturns in the VMP normally signal a continuation of the episode, description, or characterization. Higher-level boundaries in discourse (such as those between paragraphs and narrative episodes) normally correspond with deeper valleys on VMPs than do lower-level boundaries (such as those between clauses and sentences). Hence, VMPs provide surprisingly accurate graphical representations of the hierarchical structure of discourse. In general, the VMPs for "A Rose for Emily" and "Dry September" confirm this close correspondence between VMPs and narrative structure. However, VMPs are formally equivalent to unlabeled tree diagrams, and like such diagrams, they can provide only partial, not complete analogues for the structure of discourse
