A kinetic analysis of transcription initiation by the Bacillus subtilis sigma-43 RNA polymerase : the effect of the delta subunit
Creators: name: Dobinson, Katherine Frances
Publisher: name: University of British Columbia
Year: 2010

description: The initiation of transcription by the Bacillus subtilis sigma-M3 RNA polymerase at two Bacillus phage ɸ29 promoters and the effect of the delta subunit on initiation have been investigated by an in vitro kinetic analysis. The templates for the analysis were plasmids which carried the ɸ29 A2 or G2 promoter. The cloning and localization of the A2 promoter are reported here. The kinetics of RNA synthesis initiation were examined using a single-round run-off transcription assay in which multiple initiation events at a single promoter were inhibited with heparin. It was observed that the formation of heparin-resistant complexes at the A2 promoter required the presence of the initiating nucleotides, while the RNA polymerase alone was able to form heparin-resistant, non-initiated complexes at the G2 promoter. The G2 promoter was also shown by a competition assay to be a stronger promoter than A2. The effect of the delta subunit on complex formation at the two promoters was investigated with the single-round transcription assay. Delta had no effect on the formation of initiation complexes at the G2 promoter but lowered the rate and extent of complex formation at the A2 promoter. The effect of delta on the kinetic parameters of complex formation at the A2 promoter was also investigated. The data suggested that delta affects the efficiency with which the enzyme/promoter complexes undergo the transition(s) to a complex from which RNA synthesis can be initiated, although other interpretations were possible. A model for the effect of delta is proposed, in which it is postulated that the release of delta from the enzyme/promoter complex is essential for initiation. Enzyme which is associated with delta can interact with both the A2 and G2 promoters but complexes at the weaker A2 promoter do not efficiently release delta, thus slowing the formation of initiation complexes.

description: This work presents a novel general regularized distributed solution for the state estimation problem in networked systems. Resting on the graph-based representation of sensor networks and adopting a multivariate least-squares approach, the designed solution exploits the set of the available inter-sensor relative measurements and leverages a general regularization framework, whose parameter selection is shown to control the estimation procedure convergence performance. As confirmed by the numerical results, this new estimation scheme allows (i) the extension of other approaches investigated in the literature and (ii) the convergence optimization in correspondence to any (undirected) graph modeling the given sensor network.

description: The Choquet integral w.r.t. a capacity can be seen in the finite case as a parsimonious linear interpolator between vertices of $[0,1]^n$. We take this basic fact as a starting point to define the Choquet integral in a very general way, using the geometric realization of lattices and their natural triangulation, as in the work of Koshevoy. A second aim of the paper is to define a general mechanism for the bipolarization of ordered structures. Bisets (or signed sets), as well as bisubmodular functions, bicapacities, bicooperative games, as well as the Choquet integral defined for them can be seen as particular instances of this scheme. Lastly, an application to multicriteria aggregation with multiple reference levels illustrates all the results presented in the paper.

description: This paper investigates the problem of estimating three stellar atmospheric physical parameters and thirteen elemental abundances for medium-resolution spectra from Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). Typical characteristics of these spectra are their huge scale, wide range of spectral signal-to-noise ratios, and uneven distribution in parameter space.These characteristics lead to unsatisfactory results on the spectra with low temperature, high temperature or low metallicity.To this end, this paper proposes a Stellar Parameter Estimation method based on Multiple Regions (SPEMR) that effectively improves parameter estimation accuracy. On the spectra with {S/N $\geq 10$}, the precisions are 47 K, 0.08 dex, 0.03 dex respectively for the estimations of ($T_{\rm eff}$, $\log \,g$ and $\rm [Fe/H]$), 0.03 dex to 0.06 dex for elements C, Mg, Al, Si, Ca, Mn and Ni, 0.07 dex to 0.13 dex for N, O, S, K and Ti, while that of Cr is 0.16 dex.For the reference of astronomical science researchers and algorithm researchers, we released a catalog for 4.19 million medium-resolution spectra from the LAMOST DR8, experimental code, trained model, training data, and test data.

description: We study the stability of supersymmetry breaking vacuum in the presence of cosmic strings arising in the messenger sector. For certain ranges of the couplings, the desired supersymmetry breaking vacua become unstable against decay into phenomenologically unacceptable vacua. This sets constraints on the range of allowed values of the coupling constants appearing in the models and more generally on the chosen dynamics of gauge symmetry breaking.

title: Producing Japaneseness in Everday Life: Gendered biographies, locality and community-making among Japanese women in southeast London
Creators: name: Takahashi, Kaoru
Publisher: name: Goldsmiths, University of London
Year: 2022

description: This thesis examines the diverse lives of Japanese women migrants who live in southeast London. It draws on ethnographic fieldwork to question how social identities are shaped and framed by various relationships in and through migration, with particular foci on gender, life course and locality. The Japanese women who live in southeast London network extensively with their compatriots, reproducing a distinctive ‘Japaneseness’ and capitalise it in their everyday lives.

While social and cultural reproduction —particularly as this relates to their children—is central within this, their practices are also telling of their own agency in navigating the different registers of their gendered identities. They may be mothers, but they are also daughters, roles that carry with them a range of expectations and that are enacted and performed in different locations and that have enhanced significance at different points in their lives, with both intra- and inter- ethnic communities. Underpinned conceptually by an understanding of migration as an ongoing process, the study builds on existing research on Japanese women’s migration—which highlights the diversity of this population—to demonstrate their complex and multiple community making practice and belonging in which they accumulate and deploy locally-specific values and capitals.

By bringing the concepts of translocalism and biographical approach together, this thesis therefore contributes to the understanding of how gender, ethnicity and migration intersect in the everyday lives of these women. Furthermore, in disentangling their complex multi-layered lives and everyday identity negotiations, it speaks further to considerations over agency through the life course and the ways in which social world are both constitutive of and constituted by wider social structures.

description: The authors present a study of the non equilibrium statistical properties of a one dimensional hard-rod fluid dissipating energy via inelastic collisions and subject to the action of a Gaussian heat bath, simulating an external driving mechanism. They show that the description of the fluid based on the one-particle phase-space reduced distribution function, in principle necessary because of the presence of velocity dependent collisional dissipation, can be contracted to a simpler description in configurational space. Indeed, by means of a multiple-time scale method the authors derive a self-consistent governing equation for the particle density distribution function. This equation is similar to the dynamic density functional equation employed in the study of colloids, but contains additional terms taking into account the inelastic nature of the fluid. Such terms cannot be derived from a Liapunov generating functional and contribute not only to the relaxational properties, but also to the non equilibrium steady state properties. A validation of the theory against molecular dynamics simulations is presented in a series of cases, and good agreement is found.

description: We investigate the sensitivities of future neutrino oscillation experiments for measuring the neutrino mass squared differences and leptonic mixing angles independently with neutrinos and anti-neutrinos. We update the expected sensitivities of Neutrino Factories to the "atmospheric" (anti-)neutrino parameters using an optimized setup. A dedicated beta-Beam facility, in combination with a SPMIN reactor experiment, could give excellent sensitivities also to the "solar" parameters, for neutrinos and anti-neutrinos respectively. A signal of a different mass matrix for neutrinos and anti-neutrinos would imply CPT violation and non-locality of the underlying particle theory.

description: The recurrent nova RS Oph experienced an outburst in 2006, 21 years after its previous explosion in 1985, as expected. It was observed at almost all wavelengths, and important information about its properties is still being extracted. We present theoretical models of the explosion of this fascinating object, which indicate that the mass of the accreting white dwarf should be very close to the Chandrasekhar mass, to allow for such a short recurrence period. In addition, since models suggest that this nova ejects less mass than it accretes, it is an excellent candidate for a thermonuclear supernova explosion, in about $10^5-10^7$ years from now. We also analyze the emission of soft gamma-rays by RS Oph detected with the BAT instrument onboard Swift, and with the PCA onboard RXTE. We rule out that this emission has its origin in radioactive decays in the expanding nova envelope.

description: Recently, Fasano, Rebaudo, Durante and Petrone (2019) provided closed-form expressions for the filtering, predictive and smoothing distributions of multivariate dynamic probit models, leveraging on unified skew-normal distribution properties. This allows to develop algorithms to draw independent and identically distributed samples from such distributions, as well as sequential Monte Carlo procedures for the filtering and predictive distributions, allowing to overcome computational bottlenecks that may arise for large sample sizes. In this paper, we briefly review the above-mentioned closed-form expressions, mainly focusing on the smoothing distribution of the univariate dynamic probit. We develop a variational Bayes approach, extending the partially factorized mean-field variational approximation introduced by Fasano, Durante and Zanella (2019) for the static binary probit model to the dynamic setting. Results are shown for a financial application.

sottolinea come il rapporto tra geografia e filosofia attenda ancora, in larga
parte, di essere analizzato. La responsabilità, secondo l’autore, va ripartita in egual misura tra geografi e filosofi. I primi hanno troppo spesso inteso come pericolose deviazioni quei tentativi di elaborare un’immagine della Terra che non fosse un mero calco della rappresentazione cartografica. I secondi si sono invece generalmente disinteressati a una disciplina che sembra offrire pochi appigli per una riflessione critica, a causa del suo ambiguo statuto epistemologico, a metà strada tra il fisico e l’umano (Tanca, 2012, p. 13).

description: Geography and philosophy: instructions for use
This article explores the relationships existing between geography and philosophy. The absence in the past of a serious reflection on the subject today gives way to virtuous connections where the two disciplines interact with each other. First of all, the paper analyses the different ways in which this relationship is studied: proceeding by themes and problems and identifying one or more keywords to link the investigation
to a sufficient number of issues without over-wide generalizations; focusing on some concepts with a historical-diachronic reading in a long-term perspective; showing four dialectical categories: Geography of Philosophy, Philosophy of Geography, Geography in Philosophy and Philosophy in Geography. Then the article focuses on “cultural turn” and conflictual relationship between the “principle of evidence” and the “pertinence principle” in geography. In conclusion, I talk about the philosophy of geographers through a reference to some theoretical positions in Italian geography.

Géographie et philosophie : mode d’emploi Cette contribution explore les relations entre géographie et philosophie. L’absence dans le passé d’une réflexion sérieuse sur ce sujet cède aujourd’hui la place à des liens vertueux où les deux disciplines interagissent entre elles. Tout d’abord, l’article analyse les différentes manières dont cette relation est étudiée: en procédant par thèmes et
problèmes et identifiant un ou plusieurs mots-clés pour relier l’enquête à un nombre suffisant de questions sans généralisations trop générales; en concentrant sur certains concepts avec une lecture historico-iachronique dans une perspective à long terme; en montrant quatre catégories dialectiques: Géographie de la Philosophie, Philosophie de la Géographie, la Géographie dans la Philosophie et la Philosophie dans la Géographie. Ensuite l’article se concentre sur le “tournant culturel” et la relation conflictuelle entre le « principe d’évidence » et le « principe de pertinence » en géographie. En conclusion, on parle de la philosophie des géographes à travers des références aux positions théoriques émergé dans la géographie italienne.

description: A Look from Philosophy on Geography: two visions of the world,
a community of problems
This article is written from the point of view of philosophy and seeks to contribute to the very complex question of the links between philosophy and geography. Philosophy and geography are here taken in their most original conceptions, respectively, as the knowledge of the first principles of the world and as a description of the Earth in the extent of its visible surface. In 1. we briefly present possible points of view to understand this articulation, by highlighting some moments in the history of ideas where this convergence was close. In 2. we discuss the topics “philosophy in geography” and “philosophy of geography”. In 3. we propose to approach these two fundamental branches of knowledge
through a community of problems, whose answers have never failed to produce contradictory solutions. A possible way of reunification, for both philosophy and geography, may be the adoption of a mediation thinking and the choice of synthetic categories, such as landscape, capable of overcoming the antinomies that have been at the basis of the divorce between science and philosophy, natural world and human world.

Un regard de la philosophie sur la géographie. Deux visions
du monde, une communauté de problèmes
Cet article est écrit du point de vue de la philosophie et cherche à contribuer à la question très complexe des articulations entre philosophie et géographie. Philosophie et géographie sont ici prises dans leurs conceptions les plus originales, respectivement, comme la connaissance des premiers principes du monde et comme une description de la Terre dans l’étendue de sa surface visible. Dans 1. on présente brièvement des points de vue possibles pour comprendre cette articulation, en soulignant quelques moments de l’histoire des idées où cette convergence fut étroite. Dans 2. on discute le sens des expressions «philosophie dans la géographie» et «philosophie de la géographie», tout en soulignant leurs différences. Dans 3. On propose l’approche ces deux savoirs fondamentaux à travers une communauté de problèmes, dont les réponses n’ont jamais manqué de produire des solutions contradictoires. Une voie possible de réunification, tant pour la philosophie que pour la géographie, peut se trouver dans une pensée des médiations et dans le choix de catégories synthétiques, telles que le paysage, capables de surmonter les antinomies qui ont été à la base du divorce entre science et philosophie, entre monde naturel et monde humain.

description: The present work is a part of a larger program to construct explicit combinatorial models for the (indecomposable) regular representation of the nilpotent factor $N$ in the Iwasawa decomposition of a semi-simple Lie algebra $\mathfrak g$, using the restrictions to $N$ of the simple finite dimensional modules of $\mathfrak g$. Such a description is given in \cite{[ABW]}, for the cas $\mathfrak g=\mathfrak{sl}(n)$. Here, we give the analog for the rank 2 semi simple Lie algebras (of type $A_1\times A_1$, $A_2$, $C_2$ and $G_2$). The algebra $\mathbb C[N]$ of polynomial functions on $N$ is a quotient, called reduced shape algebra of the shape algebra for $\mathfrak g$. Basis for the shape algebra are known, for instance the so called semi standard Young tableaux (see \cite{[ADLMPPrW]}). We select among the semi standard tableaux, the so called quasi standard ones which define a kind basis for the reduced shape algebra.

description: Crabwalk
Following on from the reading of Strabo Prolegomena, a work in which the profound link between philosophy and geography is affirmed, and from the comparison between the “Greco-Roman” geographer and the methodological and epistemological aspects contained in the main production of Friedrich Ratzel, the geographer of the State, the present work tries to demonstrate how this connection meets the political matrix which is at the base of the possibility of practicing the “explanation” of the earth, opposed to apparently neutral “descriptions”. Subsequently, according to the thesis of Foucault which states that the ownership of the exercise of power today can no longer be ascribed only to a single subject, the State, the capillarity and pervasiveness of power relations within each form of relationship must be recognized. These relationships, often not particularly visible, affect the “production” and evolution of the geographical space. Consequently, the link between power, space and knowledge must be the subject-matter of geographical reflection. For the latter, therefore, the path to be followed leads far from the mere description-measurement of the visible sphere, in order to reacquire the critical dimension in compliance with its own origins.

En crabe
Le travail compare les Prolegomena de Strabon, oeuvre dans laquelle s’affirme le lien intime entre philosophie et géographie et les aspects méthodologiques et épistémologiques contenus dans la production principale de Friedrich Ratzel, le géographe de l’État. De cette comparaison émerge un lien qui rencontre la matrice politique sur laquelle se fonde l’explication de la Terre, par opposition à des “descriptions” apparemment neutrales. Par la suite, en acceptant la thèse de Foucault selon laquelle la propriété de l’exercice du pouvoir aujourd’hui ne peut plus être attribuée à un seul sujet, l’État, nous
devons reconnaître la capillarité et l’omniprésence des rapports de pouvoir dans tout type de relation. Ces rapports, souvent peu visibles, conditionnent la “production” et l’évolution de l’espace géographique. Par conséquence, la relation entre pouvoir, espace et connaissance doit être l’objet de réflexion de la géographie. Pour la géographie, donc, le tracé à suivre conduit loin de la simple description-mesure du visible, afin de retrouver, dans le respect de ses propres origines, la dimension critique de la connaissance.

description: We undertake a detailed numerical study of the twin phenomena of stochastic and vibrational resonance in a discrete model system in the presence of bichromatic input signal. A two parameter cubic map is used as the model that combines the features of both bistable and threshold settings. Our analysis brings out several interesting results, such as, the existence of a cross over behaviour from vibrational to stochastic resonance and the possibility of using stochastic resonance as a filter for the selective detection/transmission of the component frequencies in a composite signal. The study also reveals a fundamental difference between the bistable and threshold mechanisms with respect to amplification of a multi signal input.

description: We present in an unified and detailed way the Nested Bethe Ansatz for closed spin chains based on Y(gl(n)), Y(gl(m|n)), U_q(gl(n)) or U_q(gl(m|n)) (super)algebras, with arbitrary representations (i.e. `spins') on each site of the chain. In particular, the case of indecomposable representations of superalgebras is studied. The construction extends and unifies the results already obtained for spin chains based on Y(gl(n)) or U_q(gl(n)) and for some particular super-spin chains. We give the Bethe equations and the form of the Bethe vectors. The case of gl(2|1), gl(2|2$ and gl(4|4) superalgebras (that are related to AdS/CFT correspondence) is also detailed.

description: The nucleus-nucleus interaction potentials in heavy-ion fusion reactions are extracted from the microscopic time-dependent Hartree-Fock theory for mass symmetric reactions $^{16}$O${}+^{16}$O, $^{40}$Ca${}+^{40}$Ca, $^{48}$Ca${}+^{48}$Ca and mass asymmetric reactions $^{16}$O$ +^{40,48}$Ca, $^{40}$Ca${}+^{48}$Ca, $^{16}$O+$^{208}$Pb, $^{40}$Ca+$^{90}$Zr. When the center-of-mass energy is much higher than the Coulomb barrier energy, potentials deduced with the microscopic theory identify with the frozen density approximation. As the center-of-mass energy decreases and approaches the Coulomb barrier, potentials become energy dependent. This dependence signs dynamical reorganization of internal degrees of freedom and leads to a reduction of the "apparent" barrier felt by the two nuclei during fusion of the order of $2-3 %$ compared to the frozen density case. Several examples illustrate that the potential landscape changes rapidly when the center-of-mass energy is in the vicinity of the Coulomb barrier energy. The energy dependence is expected to have a significant role on fusion around the Coulomb barrier.

Il piano dell’oceano: James Cook e Immanuel Kant

description: The Ocean “plan”: James Cook and Immanuel Kant
The main purpose of this paper is to present and discuss a hypothesis concerning the relationship between Kant’s first Critique (1781) and Cook’s second voyage into the high southern latitudes (1772-1775). Starting from the Journal de bord by Derrida (2000), it considers the geographical lines traced by Cook function as guiding tools that intersect the metaphysics traced by Kant.

Le plateau de l’océan: James Cook et Immanuel Kant Cet essai vise à étudier la relation entre le philosophe Emmanuel Kant et l’explorateur James Cook. Croyant que le récit du deuxième voyage de James Cook aux hautes latitudes du sud (1772-1775) est le sous-texte géographique de la première critique de Kant, nous démarrons de l’imaginaire aquatique et insulaire de Derrida et de son suggestif «Journal de bord» (Derrida, 2000, nous approchons du philosophe Kant ainsi que du capitaine Cook pour amarrer enfin notre bateau sur les rives, jusqu’à maintenant si peu considérées, des références et des citations qui tant nous semblent établir une communication et une ressemblance entre les deux. Notre travail veut donc démontrer que l’analogie entre la raison cartographique et la raison pure, étudiée par Franco Farinelli (2009), est celle du plan exploratoire développé par James Cook.

description: A new class of cylindrically symmetric inhomogeneous string cosmological models is investigated. To get the deterministic solution, it has been assumed that the expansion ($θ$) in the model is proportional to the eigen value $σ^{1}_{1}$ of the shear tensor $σ^{i}_{j}$. The physical and geometric aspects of the model are also discussed.

description: Geography and Spatial turn according to Augustin Berque
The purpose of this study is to research the connection between geography and philosophy from a geographical standpoint. In this respect, acknowledged the spatial turn occurred in several disciplines, the study examines the philosophical foundation of Augustin Berque’s geography. In particular, it questions the ideas he outlined in some
chapters (Lieu, Univers, Mouvance) of his seminal work: Écoumène. Introduction à l’étude des milieux humains. The focus will be on the category of médiance and the idea that spatiality is a basic trait in human beings.

A New Spin Foam Model for 4d Gravity

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: Starting from Plebanski formulation of gravity as a constrained BF theory we propose a new spin foam model for 4d Riemannian quantum gravity that generalises the well-known Barrett-Crane model and resolves the inherent to it ultra-locality problem. The BF formulation of 4d gravity possesses two sectors: gravitational and topological ones. The model presented here is shown to give a quantization of the gravitational sector, and is dual to the recently proposed spin foam model of Engle et al. which, we show, corresponds to the topological sector. Our methods allow us to introduce the Immirzi parameter into the framework of spin foam quantisation. We generalize some of our considerations to the Lorentzian setting and obtain a new spin foam model in that context as well.

description: Long-distance quantum communication requires quantum repeaters to overcome photon loss in optical fibers. Here we demonstrate a repeater node with two memory atoms in an optical cavity. Both atoms are individually and repeatedly entangled with photons that are distributed until each communication partner has independently received one of them. An atomic Bell-state measurement followed by classical communication serves to establish a key. We demonstrate scaling advantage of the key rate, increase the effective attenuation length by a factor of two, and beat the error-rate threshold of 11\% for unconditionally secure communication, the corner stones for repeater-based quantum networks.
Geo-ontologie, prospettivismo ontologico e geografia del senso comune

Year: 2018

description: Geo-ontologies, ontological perspectivalism and common sense
geography
In addition to constituting part of the conceptual background of geo-ontologies, philosophy and geography can provide some prospects of research that may be useful for improving the general aims of informativeness and accessibility required by such tools – especially, when they have to describe multidisciplinary domains. Accordingly, the
purpose of this article is analyzing some of these prospects. The first two paragraphs are devoted to the philosophical reflection, showing some ontological approaches to GIS and geo-ontologies, and how ‘ontological perspectivalism’ can supply a platform for integrating conceptualizations coming from different domains of investigation. The third paragraph is focused on the ‘common sense geography’, analyzing three different
meanings of such a locution and clarifying how it can improve the accessibility of geo-ontologies.

Géo-ontologies, perspectivisme ontologique et géographie du sens
commun
Le but de ces pages est de montrer comment la philosophie et la géographie font partie du fond conceptuel des géo-ontologies. En outre, il s’agira de montrer comme elles peuvent fournir des perspectives de recherche utiles pour répondre aux besoins en informativité et en accessibilité requis par de tels outils informatiques – en particulier
lorsque ceux-ci doivent décrire des domaines d’enquête  multidisciplinaire. Dans les deux premiers paragraphes, l’accent est mis sur la réflexion philosophique, soulignant comment l’ontologie a abordé le domaine des SIG et des géo-ontologies, et comment le perspectivisme ontologique peut fournir un élément de synthèse pour différents domaines de recherche. Le troisième paragraphe (et les sous-paragraphes qui le composent) est plutôt consacré à la géographie du sens commun, en particulier pour en analyser trois significations fonctionnelles différentes afin d’en clarifier son efficacité pour améliorer l’accessibilité d’une géo-ontologie.
