  1. The simplicial Ricci tensor

    International Nuclear Information System (INIS)

    Alsing, Paul M; McDonald, Jonathan R; Miller, Warner A

    2011-01-01

    The Ricci tensor (Ric) is fundamental to Einstein's geometric theory of gravitation. The three-dimensional Ric of a spacelike surface vanishes at the moment of time symmetry for vacuum spacetimes. The four-dimensional Ric is the Einstein tensor for such spacetimes. More recently, the Ric was used by Hamilton to define a nonlinear, diffusive Ricci flow (RF) that was fundamental to Perelman's proof of the Poincare conjecture. Analytic applications of RF can be found in many fields including general relativity and mathematics. Numerically it has been applied broadly to communication networks, medical physics, computer design and more. In this paper, we use Regge calculus (RC) to provide the first geometric discretization of the Ric. This result is fundamental for higher dimensional generalizations of discrete RF. We construct this tensor on both the simplicial lattice and its dual and prove their equivalence. We show that the Ric is an edge-based weighted average of deficit divided by an edge-based weighted average of dual area-an expression similar to the vertex-based weighted average of the scalar curvature reported recently. We use this Ric in a third and independent geometric derivation of the RC Einstein tensor in arbitrary dimensions.

  3. Implementing quantum Ricci curvature

    Science.gov (United States)

    Klitgaard, N.; Loll, R.

    2018-05-01

    Quantum Ricci curvature has been introduced recently as a new, geometric observable characterizing the curvature properties of metric spaces, without the need for a smooth structure. Besides coordinate invariance, its key features are scalability, computability, and robustness. We demonstrate that these properties continue to hold in the context of nonperturbative quantum gravity, by evaluating the quantum Ricci curvature numerically in two-dimensional Euclidean quantum gravity, defined in terms of dynamical triangulations. Despite the well-known, highly nonclassical properties of the underlying quantum geometry, its Ricci curvature can be matched well to that of a five-dimensional round sphere.

  4. Introducing quantum Ricci curvature

    Science.gov (United States)

    Klitgaard, N.; Loll, R.

    2018-02-01

    Motivated by the search for geometric observables in nonperturbative quantum gravity, we define a notion of coarse-grained Ricci curvature. It is based on a particular way of extracting the local Ricci curvature of a smooth Riemannian manifold by comparing the distance between pairs of spheres with that of their centers. The quantum Ricci curvature is designed for use on non-smooth and discrete metric spaces, and to satisfy the key criteria of scalability and computability. We test the prescription on a variety of regular and random piecewise flat spaces, mostly in two dimensions. This enables us to quantify its behavior for short lattices distances and compare its large-scale behavior with that of constantly curved model spaces. On the triangulated spaces considered, the quantum Ricci curvature has good averaging properties and reproduces classical characteristics on scales large compared to the discretization scale.

  5. Viscous Ricci dark energy

    International Nuclear Information System (INIS)

    Feng Chaojun; Li Xinzhou

    2009-01-01

    We investigate the viscous Ricci dark energy (RDE) model by assuming that there is bulk viscosity in the linear barotropic fluid and the RDE. In the RDE model without bulk viscosity, the universe is younger than some old objects at certain redshifts. Since the age of the universe should be longer than any objects living in the universe, the RDE model suffers the age problem, especially when we consider the object APM 08279+5255 at z=3.91 with age t=2.1 Gyr. In this Letter, we find that once the viscosity is taken into account, this age problem is alleviated.

  6. Ricci-flat branes

    International Nuclear Information System (INIS)

    Brecher, D.; Perry, M.J.

    2000-01-01

    Up to overall harmonic factors, the D8-brane solution of the massive type IIA supergravity theory is the product of nine-dimensional Minkowski space (the world-volume) with the real line (the transverse space). We show that the equations of motion allow for the world-volume metric to be generalised to an arbitrary Ricci-flat one. If this nine-dimensional Ricci-flat manifold admits Killing spinors, then the resulting solutions are supersymmetric and satisfy the usual Bogomol'nyi bound, although they preserve fewer than the usual one half of the supersymmetries. We describe the possible choices of such manifolds, elaborating on the connection between the existence of Killing spinors and the self-duality condition on the curvature two-form. Since the D8-brane is a domain wall in ten dimensions, we are led to consider the general case: domain walls in any supergravity theory. Similar considerations hold here also. Moreover, it is shown that the world-volume of any magnetic brane - of which the domain walls are a specific example - can be generalised in precisely the same way. The general class of supersymmetric solutions have gravitational instantons as their spatial sections. Some mention is made of the world-volume solitons of such branes

  7. Quantum wormhole as a Ricci flow

    OpenAIRE

    Dzhunushaliev, Vladimir

    2008-01-01

    The idea is considered that a quantum wormhole in a spacetime foam can be described as a Ricci flow. In this interpretation the Ricci flow is a statistical system and every metric in the Ricci flow is a microscopical state. The probability density of the microscopical state is connected with a Perelman's functional of a rescaled Ricci flow.

  8. OF SOCIAL NETWORKS AND LINGUISTIC INFLUENCE: THE LANGUAGE OF ROBERT LOWTH AND HIS CORRESPONDENTS

    Directory of Open Access Journals (Sweden)

    Ingrid Tieken-Boon van Ostade

    2005-06-01

    Full Text Available Analysing the unpublished correspondence of Robert Lowth, author of A Short Introduction to English Grammar (1762, this article attempts to find evidence of linguistic influence between people belonging to the same social network. Such evidence is used to try and determine where Lowth found the linguistic norm he presented in his grammar. Adding to the data presented by Nevalainen and Raumolin Bmnberg (2003 on the basis of their study of fourteen morphosyntactic items in the Corpus of Early English Correspondence, a detailed analysis is presented of eighteenth-century English. One of the results is an explanation for the presence in Lowth's grammar of the stricture against double negation at a time when double negation was no longer in current use.

  9. Contemporary Studies Network Roundtable: Responding to Robert Macfarlane’s ‘Generation Anthropocene’

    Directory of Open Access Journals (Sweden)

    Rachel Sykes

    2017-02-01

    Full Text Available In April 2016, 'The Guardian' published ‘Generation Anthropocene: How humans have altered the planet forever’ by the celebrated academic and nature writer Robert Macfarlane. Reflecting on the article’s importance as a critical experiment and, perhaps, a vital form of public engagement, Contemporary Studies Network (CSN asked six of its members, working across very different areas of literary and cultural studies, to respond to and extend Macfarlane’s article, mapping the different ways in which literary scholars might approach the age of the Anthropocene. Conducted via email, this roundtable conversation asks to what extent the Anthropocene marks a new era in literary criticism, how exactly it extends preexisting strands of ecocriticism and trauma studies, and what the global scope of the term might be beyond the confines of the Western literary canon. Discussion ranges from issues of temporality to genre and form and it also addresses Macfarlane’s rhetoric, his call to arms for those working in the humanities, for a more comprehensive investigation in to the roles of literature and art in responding to and representing what may become a new epoch.

  10. Ricci inheritance symmetry in general relativity

    International Nuclear Information System (INIS)

    Bokhari, A.H.; Al-Dweik, A.; Zaman, F.D.; Karim, M.; Kubel, D.

    2010-01-01

    In an earlier paper (see Nuovo Cimento B, 19 (2004) 1187) it was conjectured that none of the well-known spherically symmetric static space-time solutions of the Einstein equations admit non-trivial Ricci inheritance symmetry. In this paper we discuss Ricci inheritance (R I) symmetry in three well-known non static spherically symmetric space-time metrics and show that our conjecture is also valid in non-static space-time metrics.

  11. Ricci flow and geometrization of 3-manifolds

    CERN Document Server

    Morgan, John W

    2010-01-01

    This book is based on lectures given at Stanford University in 2009. The purpose of the lectures and of the book is to give an introductory overview of how to use Ricci flow and Ricci flow with surgery to establish the Poincar� Conjecture and the more general Geometrization Conjecture for 3-dimensional manifolds. Most of the material is geometric and analytic in nature; a crucial ingredient is understanding singularity development for 3-dimensional Ricci flows and for 3-dimensional Ricci flows with surgery. This understanding is crucial for extending Ricci flows with surgery so that they are defined for all positive time. Once this result is in place, one must study the nature of the time-slices as the time goes to infinity in order to deduce the topological consequences. The goal of the authors is to present the major geometric and analytic results and themes of the subject without weighing down the presentation with too many details. This book can be read as an introduction to more complete treatments of ...

  12. Statefinder diagnosis for Ricci dark energy

    International Nuclear Information System (INIS)

    Feng Chaojun

    2008-01-01

    Statefinder diagnostic is a useful method which can differ one dark energy model from each others. In this Letter, we apply this method to a holographic dark energy model from Ricci scalar curvature, called the Ricci dark energy model (RDE). We plot the evolutionary trajectories of this model in the statefinder parameter-planes, and it is found that the parameter of this model plays a significant role from the statefinder viewpoint. In a very special case, the statefinder diagnostic fails to discriminate LCDM and RDE models, thus we apply a new diagnostic called the Om diagnostic proposed recently to this model in this case in Appendix A and it works well

    2012-01-01

    In this paper, we prove several differential Harnack inequalities under a coupled Ricci flow. As applications, we get Harnack inequalities for positive solutions of backward heat-type equations with potentials under the coupled Ricci flow. We also derive Perelman’s differential Harnack inequality for fundamental solution of the conjugate heat equation under the Ricci flow.

  16. Topological Signals of Singularities in Ricci Flow

    Directory of Open Access Journals (Sweden)

    Paul M. Alsing

    2017-08-01

    Full Text Available We implement methods from computational homology to obtain a topological signal of singularity formation in a selection of geometries evolved numerically by Ricci flow. Our approach, based on persistent homology, produces precise, quantitative measures describing the behavior of an entire collection of data across a discrete sample of times. We analyze the topological signals of geometric criticality obtained numerically from the application of persistent homology to models manifesting singularities under Ricci flow. The results we obtain for these numerical models suggest that the topological signals distinguish global singularity formation (collapse to a round point from local singularity formation (neckpinch. Finally, we discuss the interpretation and implication of these results and future applications.

    2018-01-01

    Let (Mn , g , X) be a complete generic shrinking Ricci soliton of dimension n ≥ 3. In this paper, by employing curvature inequalities, the formula of X-Laplacian for the norm square of the trace-free curvature tensor, the weak maximum principle and the estimate of the scalar curvature of (Mn , g) , we prove some rigidity results for (Mn , g , X) . In particular, it is showed that (Mn , g , X) is isometric to Rn or a finite quotient of Sn under a pointwise pinching condition. Moreover, we establish several optimal inequalities and classify those shrinking solitons for equalities.

  20. Ricci solitons, Ricci flow and strongly coupled CFT in the Schwarzschild Unruh or Boulware vacua

    International Nuclear Information System (INIS)

    Figueras, Pau; Lucietti, James; Wiseman, Toby

    2011-01-01

    The elliptic Einstein-DeTurck equation may be used to numerically find Einstein metrics on Riemannian manifolds. Static Lorentzian Einstein metrics are considered by analytically continuing to Euclidean time. The Ricci-DeTurck flow is a constructive algorithm to solve this equation, and is simple to implement when the solution is a stable fixed point, the only complication being that Ricci solitons may exist which are not Einstein. Here we extend previous work to consider the Einstein-DeTurck equation for Riemannian manifolds with boundaries, and those that continue to static Lorentzian spacetimes which are asymptotically flat, Kaluza-Klein, locally AdS or have extremal horizons. Using a maximum principle, we prove that Ricci solitons do not exist in these cases and so any solution is Einstein. We also argue that the Ricci-DeTurck flow preserves these classes of manifolds. As an example, we simulate the Ricci-DeTurck flow for a manifold with asymptotics relevant for AdS 5 /CFT 4 . Our maximum principle dictates that there are no soliton solutions, and we give strong numerical evidence that there exists a stable fixed point of the flow which continues to a smooth static Lorentzian Einstein metric. Our asymptotics are such that this describes the classical gravity dual relevant for the CFT on a Schwarzschild background in either the Unruh or Boulware vacua. It determines the leading O(N 2 c ) part of the CFT stress tensor, which interestingly is regular on both the future and past Schwarzschild horizons. (paper)

  1. Spacetimes of Weyl and Ricci type N in higher dimensions

    International Nuclear Information System (INIS)

    Kuchynka, M; Pravdová, A

    2016-01-01

    We study the geometrical properties of null congruences generated by an aligned null direction of the Weyl tensor (WAND) in spacetimes of Weyl and Ricci type N (possibly with a non-vanishing cosmological constant) in an arbitrary dimension. We prove that a type N Ricci tensor and a type III or N Weyl tensor have to be aligned. In such spacetimes, the multiple WAND has to be geodetic. For spacetimes with type N aligned Weyl and Ricci tensors, the canonical form of the optical matrix in the twisting and non-twisting cases is derived and the dependence of the Weyl and the Ricci tensors and Ricci rotation coefficients on the affine parameter of the geodetic null congruence generated by the WAND is obtained.

  2. Quasi-topological Ricci polynomial gravities

    Science.gov (United States)

    Li, Yue-Zhou; Liu, Hai-Shan; Lü, H.

    2018-02-01

    Quasi-topological terms in gravity can be viewed as those that give no contribution to the equations of motion for a special subclass of metric ansätze. They therefore play no rôle in constructing these solutions, but can affect the general perturbations. We consider Einstein gravity extended with Ricci tensor polynomial invariants, which admits Einstein metrics with appropriate effective cosmological constants as its vacuum solutions. We construct three types of quasi-topological gravities. The first type is for the most general static metrics with spherical, toroidal or hyperbolic isometries. The second type is for the special static metrics where g tt g rr is constant. The third type is the linearized quasitopological gravities on the Einstein metrics. We construct and classify results that are either dependent on or independent of dimensions, up to the tenth order. We then consider a subset of these three types and obtain Lovelock-like quasi-topological gravities, that are independent of the dimensions. The linearized gravities on Einstein metrics on all dimensions are simply Einstein and hence ghost free. The theories become quasi-topological on static metrics in one specific dimension, but non-trivial in others. We also focus on the quasi-topological Ricci cubic invariant in four dimensions as a specific example to study its effect on holography, including shear viscosity, thermoelectric DC conductivities and butterfly velocity. In particular, we find that the holographic diffusivity bounds can be violated by the quasi-topological terms, which can induce an extra massive mode that yields a butterfly velocity unbound above.

  3. Asymptotic safety of quantum gravity beyond Ricci scalars

    Science.gov (United States)

    Falls, Kevin; King, Callum R.; Litim, Daniel F.; Nikolakopoulos, Kostas; Rahmede, Christoph

    2018-04-01

    We investigate the asymptotic safety conjecture for quantum gravity including curvature invariants beyond Ricci scalars. Our strategy is put to work for families of gravitational actions which depend on functions of the Ricci scalar, the Ricci tensor, and products thereof. Combining functional renormalization with high order polynomial approximations and full numerical integration we derive the renormalization group flow for all couplings and analyse their fixed points, scaling exponents, and the fixed point effective action as a function of the background Ricci curvature. The theory is characterized by three relevant couplings. Higher-dimensional couplings show near-Gaussian scaling with increasing canonical mass dimension. We find that Ricci tensor invariants stabilize the UV fixed point and lead to a rapid convergence of polynomial approximations. We apply our results to models for cosmology and establish that the gravitational fixed point admits inflationary solutions. We also compare findings with those from f (R ) -type theories in the same approximation and pin-point the key new effects due to Ricci tensor interactions. Implications for the asymptotic safety conjecture of gravity are indicated.

  4. Ricci-Gauss-Bonnet holographic dark energy

    Science.gov (United States)

    Saridakis, Emmanuel N.

    2018-03-01

    We present a model of holographic dark energy in which the infrared cutoff is determined by both the Ricci and the Gauss-Bonnet invariants. Such a construction has the significant advantage that the infrared cutoff, and consequently the holographic dark energy density, does not depend on the future or the past evolution of the universe, but only on its current features, and moreover it is determined by invariants, whose role is fundamental in gravitational theories. We extract analytical solutions for the behavior of the dark energy density and equation-of-state parameters as functions of the redshift. These reveal the usual thermal history of the universe, with the sequence of radiation, matter and dark energy epochs, resulting in the future to a complete dark energy domination. The corresponding dark energy equation-of-state parameter can lie in the quintessence or phantom regime, or experience the phantom-divide crossing during the cosmological evolution, and its asymptotic value can be quintessencelike, phantomlike, or be exactly equal to the cosmological-constant value. Finally, we extract the constraints on the model parameters that arise from big bang nucleosynthesis.

    Since 2004 the Robert Koch-Institute has supported the formation of regional networks for prevention of the spread of methicillin-resistant Staphylococcus aureus and multiresistant pathogens (MRSA/MRP, EpiBull 5/2005)). The third meeting of the coordinators of the regional MRP networks in Germany took place on 15 and 16 December 2011. A total of 60 representatives of the Public Health Services from 12 states participated. It must be emphasized that in the meantime many successfully established networks are active and not all coordinators of existing networks could participate merely due to the organizational format. Interested parties can obtain a good overview via a link to the corresponding internet homepage of each state under http://www.rki.de → Infektionsschutz → Krankenhaushygiene → Regionale Netzwerke. In summary it was clear that the number and the activity of regional MRP networks in Germany have further increased. The networks can synergistically benefit from important experiences through the different individual focal points of each network and a corresponding exchange of ideas.

  7. An introduction to the Kähler-Ricci flow

    CERN Document Server

    Eyssidieux, Philippe; Guedj, Vincent

    2013-01-01

    This volume collects lecture notes from courses offered at several conferences and workshops, and provides the first exposition in book form of the basic theory of the Kähler-Ricci flow and its current state-of-the-art. While several excellent books on Kähler-Einstein geometry are available, there have been no such works on the Kähler-Ricci flow. The book will serve as a valuable resource for graduate students and researchers in complex differential geometry, complex algebraic geometry and Riemannian geometry, and will hopefully foster further developments in this fascinating area of research.   The Ricci flow was first introduced by R. Hamilton in the early 1980s, and is central in G. Perelman’s celebrated proof of the Poincaré conjecture. When specialized for Kähler manifolds, it becomes the Kähler-Ricci flow, and reduces to a scalar PDE (parabolic complex Monge-Ampère equation). As a spin-off of his breakthrough, G. Perelman proved the convergence of the Kähler-Ricci flow on Kähler-Einstein man...

  8. Shape signature based on Ricci flow and optimal mass transportation

    Science.gov (United States)

    Luo, Wei; Su, Zengyu; Zhang, Min; Zeng, Wei; Dai, Junfei; Gu, Xianfeng

    2014-11-01

    A shape signature based on surface Ricci flow and optimal mass transportation is introduced for the purpose of surface comparison. First, the surface is conformally mapped onto plane by Ricci flow, which induces a measure on the planar domain. Second, the unique optimal mass transport map is computed that transports the new measure to the canonical measure on the plane. The map is obtained by a convex optimization process. This optimal transport map encodes all the information of the Riemannian metric on the surface. The shape signature consists of the optimal transport map, together with the mean curvature, which can fully recover the original surface. The discrete theories of surface Ricci flow and optimal mass transportation are explained thoroughly. The algorithms are given in detail. The signature is tested on human facial surfaces with different expressions accquired by structured light 3-D scanner based on phase-shifting method. The experimental results demonstrate the efficiency and efficacy of the method.

    CERN Document Server

    Mantegazza, Carlo

    2016-01-01

    Presenting some impressive recent achievements in differential geometry and topology, this volume focuses on results obtained using techniques based on Ricci flow. These ideas are at the core of the study of differentiable manifolds. Several very important open problems and conjectures come from this area and the techniques described herein are used to face and solve some of them. The book's four chapters are based on lectures given by leading researchers in the field of geometric analysis and low-dimensional geometry/topology, respectively offering an introduction to: the differentiable sphere theorem (G. Besson), the geometrization of 3-manifolds (M. Boileau), the singularities of 3-dimensional Ricci flows (C. Sinestrari), and Kahler-Ricci flow (G. Tian). The lectures will be particularly valuable to young researchers interested in differential manifolds.

    A generalization of the charged c metric to the nonstationary case is given. The possibility of associating the energy-momentum tensor with the electromagnetic or neutrino field is discussed.

  11. Non-adiabatic perturbations in Ricci dark energy model

    International Nuclear Information System (INIS)

    Karwan, Khamphee; Thitapura, Thiti

    2012-01-01

    We show that the non-adiabatic perturbations between Ricci dark energy and matter can grow both on superhorizon and subhorizon scales, and these non-adiabatic perturbations on subhorizon scales can lead to instability in this dark energy model. The rapidly growing non-adiabatic modes on subhorizon scales always occur when the equation of state parameter of dark energy starts to drop towards -1 near the end of matter era, except that the parameter α of Ricci dark energy equals to 1/2. In the case where α = 1/2, the rapidly growing non-adiabatic modes disappear when the perturbations in dark energy and matter are adiabatic initially. However, an adiabaticity between dark energy and matter perturbations at early time implies a non-adiabaticity between matter and radiation, this can influence the ordinary Sachs-Wolfe (OSW) effect. Since the amount of Ricci dark energy is not small during matter domination, the integrated Sachs-Wolfe (ISW) effect is greatly modified by density perturbations of dark energy, leading to a wrong shape of CMB power spectrum. The instability in Ricci dark energy is difficult to be alleviated if the effects of coupling between baryon and photon on dark energy perturbations are included

    Sandhu, Romeil S; Georgiou, Tryphon T; Tannenbaum, Allen R

    2016-05-01

    Quantifying the systemic risk and fragility of financial systems is of vital importance in analyzing market efficiency, deciding on portfolio allocation, and containing financial contagions. At a high level, financial systems may be represented as weighted graphs that characterize the complex web of interacting agents and information flow (for example, debt, stock returns, and shareholder ownership). Such a representation often turns out to provide keen insights. We show that fragility is a system-level characteristic of "business-as-usual" market behavior and that financial crashes are invariably preceded by system-level changes in robustness. This was done by leveraging previous work, which suggests that Ricci curvature, a key geometric feature of a given network, is negatively correlated to increases in network fragility. To illustrate this insight, we examine daily returns from a set of stocks comprising the Standard and Poor's 500 (S&P 500) over a 15-year span to highlight the fact that corresponding changes in Ricci curvature constitute a financial "crash hallmark." This work lays the foundation of understanding how to design (banking) systems and policy regulations in a manner that can combat financial instabilities exposed during the 2007-2008 crisis.

This was done by leveraging previous work, which suggests that Ricci curvature, a key geometric feature of a given network, is negatively correlated to increases in network fragility. To illustrate this insight, we examine daily returns from a set of stocks comprising the Standard and Poor’s 500 (S&P 500) over a 15-year span to highlight the fact that corresponding changes in Ricci curvature constitute a financial “crash hallmark.” This work lays the foundation of understanding how to design (banking) systems and policy regulations in a manner that can combat financial instabilities exposed during the 2007–2008 crisis.

  16. Topologically massive gravity and Ricci-Cotton flow

    We consider topologically massive gravity (TMG), which is three-dimensional general relativity with a cosmological constant and a gravitational Chern-Simons term. When the cosmological constant is negative the theory has two potential vacuum solutions: anti-de Sitter space and warped anti-de Sitter space. The theory also contains a massive graviton state which renders these solutions unstable for certain values of the parameters and boundary conditions. We study the decay of these solutions due to the condensation of the massive graviton mode using Ricci-Cotton flow, which is the appropriate generalization of Ricci flow to TMG. When the Chern-Simons coupling is small the AdS solution flows to warped AdS by the condensation of the massive graviton mode. When the coupling is large the situation is reversed, and warped AdS flows to AdS. Minisuperspace models are constructed where these flows are studied explicitly.

    Full text: Currently the accelerated expansion of the universe has been strongly confirmed by some independent experiments such as the Cosmic Microwave Background Radiation (CMBR) and Sloan Digital Sky Survey (SDSS). In an attempt to explain this phenomenon there are two possible paths; first option - propose corrections to general relativity, second option - assuming that there is a dominant component of the universe, a kind of antigravity called dark energy. Any way that we intend to follow, there are numerous models that attempt to explain this effect. One of the models of modified gravity that has stood out in recent years is the Chern-Simons modified gravity. This modification consists in the addition of the Pontryagin density, which displays violation of parity symmetry in Einstein-Hilbert action. From among the various models proposed for dark energy there are some that are based on the holographic principle, known as holographic dark energy. Such models are based on the idea that the energy density of a given system is proportional to the inverse square of some characteristic length of the system. From these studies, here we consider the model proposed by Gao et. al., a model of dark energy where the characteristic length is given by the average radius of the Ricci scalar. Thus, the dark energy density is proportional to the Ricci scalar, i.e., ρ{sub x} ∝ R. It is a phenomenologically viable model and displays results similar to that presented by the cosmological model ACDM. In this work, we have considered the Ricci dark energy model in the dynamic Chern-Simons modified gravity. We show that in this context the evolution of the scale factor is similar to that displayed by the modified Chaplygin gas. (author)

    This article provides an attempt to extend concepts from the theory of Riemannian manifolds to piecewise linear (p.l.) spaces. In particular we propose an analogue of the Ricci tensor, which we give the name of an Einstein vector field . On a given set of p.l. spaces we define and discuss (normalized) Einstein flows. p.l. Einstein metrics are defined and examples are provided. Criteria for flows to approach Einstein metrics are formulated. Second variations of the total scalar curvature at a specific Einstein space are calculated. (paper)

    While general relativity is an extremely robust theory to describe the gravitational interaction in our Universe, it is expected to fail close to singularities like the cosmological ones. On the other hand, it is well known that some dark energy models might induce future singularities; this can be the case for example within the setup of the Holographic Ricci Dark Energy model (HRDE). On this work, we perform a cosmological quantisation of the HRDE model and obtain under which conditions a cosmic doomsday can be avoided within the quantum realm. We show as well that this quantum model not only avoid future singularities but also the past Big Bang.

  5. Spontaneous compactification and Ricci-flat manifolds with torsion

    1985-06-01

    The Freund-Rubin mechanism is based on the equation Rsub(ik)=lambdagsub(ik) (where lambda>0), which, via Myers' Theorem, implies ''spontaneous'' compactification. The difficulties connected with the cosmological constant in this approach can be resolved if torsion is introduced and lambda set equal to zero, but then compactification ''by hand'' is necessary, since the equation Rsub(ik)=0 can be satisfied both on compact and on non-compact manifolds. In this paper we discuss the global geometry of Ricci-flat manifolds with torsion, and suggest ways of restoring the ''spontaneity'' of the compactification. (author)

Among other things, we prove that, if ( M, ω) is a smooth compact symplectic 4-manifold such that {b_2^+(M) > 1} and let g( t), t ∈ [0, ∞), be a solution to (1.3) on M whose Ricci curvature satisfies that |Ric( g( t))| ≤ 3 and additionally χ( M) = 3τ ( M) > 0, then there exists an {min mathbb{N}} , and a sequence of points { x j, k ∈ M}, j = 1, . . . , m, satisfying that, by passing to a subsequence, {{(M, g(tk+t), x_{1,k},ldots, x_{m,k})stackrel{d_{GH}}longrightarrow ({\\coprod limitsm_{j=1}} N_j , g_{infty}, x_{1,infty}, ldots, x_{m,infty}),}} t ∈ [0, ∞), in the m-pointed Gromov-Hausdorff sense for any sequence t k → ∞, where ( N j , g ∞), j = 1, . . . , m, are complete complex hyperbolic orbifolds of complex dimension 2 with at most finitely many isolated orbifold points. Moreover, the convergence is C ∞ in the non-singular part of {\\coprod _1^m Nj} and {text{Vol}_{g0}(M)=sum_{j=1}mtext{Vol}_{g_{infty}}(Nj)} , where χ( M) (resp. τ( M)) is the Euler characteristic (resp. signature) of M.

    Ricci flow is a powerful technique using a heat-type equation to deform Riemannian metrics on manifolds to better metrics in the search for geometric decompositions. With the fourth part of their volume on techniques and applications of the theory, the authors discuss long-time solutions of the Ricci flow and related topics. In dimension 3, Perelman completed Hamilton's program to prove Thurston's geometrization conjecture. In higher dimensions the Ricci flow has remarkable properties, which indicates its usefulness to understand relations between the geometry and topology of manifolds. This b

As a special case, we employ scaling arguments to derive a linear-type matrix LYH estimate. The new LYH quadratics obtained in this way are associated to the system of the Ricci flow coupled to a 1-form and a 2...

    Full Text Available This January, while preparing a new course, Robert Seydel was struck and killed by an unexpected heart attack. He was a critically under-appreciated artist and one of the most beloved and admired professors at Hampshire College.At the time of his passing, Seydel was on the brink of a major artistic and career milestone. His Book of Ruth was being prepared for publication by Siglio Press. His publisher describes the book as: “an alchemical assemblage that composes the life of his alter ego, Ruth Greisman— spinster, Sunday painter, and friend to Joseph Cornell and Marcel Duchamp. Through collages, drawings, and journal entries from Ruth’s imagined life, Seydel invokes her interior world in novelistic rhythms.”This convergence of his professional triumph with the tragedy of his death makes now a particularly appropriate time to think about Robert Seydel and his work. This feature contains a selection of excerpts from Book of Ruth (courtesy of Siglio Press alongside a pair of texts remembering him and giving critical and biographical insights into his art and his person. These texts, from a former student and a colleague respectively, were originally prepared for Seydel's memorial at Hampshire College and have since been revised for publication in continent.

    2015-01-01

    In this work we investigate Ricci flows of almost Kaehler structures on Lie algebroids when the fundamental geometric objects are completely determined by (semi) Riemannian metrics, or effective) regular generating Lagrange/ Finsler, functions. There are constructed canonical almost symplectic connections for which the geometric flows can be represented as gradient ones and characterized by nonholonomic deformations of Grigory Perelman's functionals. The first goal of this paper is to define such thermodynamical type values and derive almost K\\"ahler - Ricci geometric evolution equations. The second goal is to study how fixed Lie algebroid, i.e. Ricci soliton, configurations can be constructed for Riemannian manifolds and/or (co) tangent bundles endowed with nonholonomic distributions modelling (generalized) Einstein or Finsler - Cartan spaces. Finally, there are provided some examples of generic off-diagonal solutions for Lie algebroid type Ricci solitons and (effective) Einstein and Lagrange-Finsler algebro...

    We perform the stability analysis of Schwarzschild-AdS (SAdS) black hole in the Einstein-Ricci cubic gravity. It shows that the Ricci tensor perturbations exhibit unstable modes for small black holes. We call this the mass-induced instability of SAdS black hole because the instability of small black holes arises from the massiveness in the linearized Einstein-Ricci cubic gravity, but not a feature of higher-order derivative theory giving ghost states. Also, we point out that the correlated stability conjecture holds for the SAdS black hole by computing the Wald entropy of SAdS black hole in Einstein-Ricci cubic gravity.

    A keynote speaker at Outlook 2001 conference, Robert Priddle, Executive Director of the International Energy Agency, provided a realistic assessment of the opportunities for a change in the energy supply mix in the light of the growing international debate about the design of a sustainable energy future. World energy supply today is based firmly on fossil fuels. Furthermore, projections of future supply, such as that made in the reference case of the recent World Energy Outlook by the IEA, indicate little change. Yet government's remain deeply engaged in efforts to reshape energy markets including (despite the failure of COP-6 in The Hague last November) efforts to curb national emissions of greenhouse gases, in particular from the energy sector. Australia has made considerable progress in developing and applying life cycle analysis to the energy sector. This effort demonstrates opportunities to combine, for example, coal seam methane capture, coal and biomass co-combustion, coal power generation and steel production and thus to reduce emissions by up to 15%. The prospect is that even with effective carbon constraints reflected in fuel prices, coal can remain a competitive fuel choice for longer than many analysts imagine. The outcome does not rely on exotic technology development, rather it requires the necessary market signals to create new business partnerships

    We apply the statefinder hierarchy plus the fractional growth parameter to explore the extended Ricci dark energy (ERDE) model, in which there are two independent coefficients α and β. By adjusting them, we plot evolution trajectories of some typical parameters, including the Hubble expansion rate E, deceleration parameter q, the third and fourth-order hierarchy S{sub 3}{sup (1)} and S{sub 4}{sup (1)}, and the fractional growth parameter ε, respectively, as well as several combinations of them. For the case of variable α and constant β, in the low-redshift region the evolution trajectories of E are in high degeneracy and that of q separate somewhat. However, the ΛCDM model is confounded with ERDE in both of these cases. S{sub 3}{sup (1)} and S{sub 4}{sup (1)}, especially the former, perform much better. They can differentiate well only varieties of cases within ERDE except ΛCDM in the low-redshift region. For the high-redshift region, combinations {S_n"("1"), ε} can break the degeneracy. Both of {S_3"("1"), ε} and {S_4"("1"), ε} have the ability to discriminate ERDE with α = 1 from ΛCDM, of which the degeneracy cannot be broken by all the before-mentioned parameters. For the case of variable β and constant α, S{sub 3}{sup (1)}(z) and S{sub 4}{sup (1)}(z) can only discriminate ERDE from ΛCDM. Nothing but pairs {S_3"("1"), ε} and {S_4"("1"), ε} can discriminate not only within ERDE but also ERDE from ΛCDM. Finally, we find that S{sub 3}{sup (1)} is surprisingly a better choice to discriminate within ERDE itself, and ERDE from ΛCDM as well, rather than S{sub 4}{sup (1)}. (orig.)

    The brane-world model proposed by Dvali, Gabadadze and Porrati (DGP) leads to an accelerated universe without cosmological constant or other form of dark energy for the positive branch (element of = +1). For the negative branch (element of = -1) we have investigated the behavior of a model with an holographic Ricci-like dark energy and dark matter, where the IR cutoff takes the form αH{sup 2} + βH, H being the Hubble parameter and α, β positive constants of the model. We perform an analytical study of the model in the late-time dark energy dominated epoch, where we obtain a solution for r{sub c}H(z), where r{sub c} is the leakage scale of gravity into the bulk, and conditions for the negative branch on the holographic parameters α and β, in order to hold the conditions of weak energy and accelerated universe. On the other hand, we compare the model versus the late-time cosmological data using the latest type Ia supernova sample of the Joint Light-curve Analysis (JLA), in order to constrain the holographic parameters in the negative branch, as well as r{sub c}H{sub 0} in the positive branch, where H{sub 0} is the Hubble constant. We find that the model has a good fit to the data and that the most likely values for (r{sub c}H{sub 0}, α, β) lie in the permitted region found from an analytical solution in a dark energy dominated universe. We give a justification to use a holographic cutoff in 4D for the dark energy in the 5-dimensional DGP model. Finally, using the Bayesian Information Criterion we find that this model is disfavored compared with the flat ΛCDM model. (orig.)

    2018-01-01

    This paper is devoted to explore the RICCI and MCs (Matter Collineations of the Som-Ray Chaudhary spacetime. The spacetime under consideration is one of the spatially homogeneous and rotating spacetimes. Collineations are the some kinds of the Lie symmetries. To discuss the required collineations we have used the RICCI and energy momentum tensors. As the RICCI tensor is formulated from the metric tensor, it must possess its symmetries. RCs (RICCI Collineations) leads to conservation laws. On the other hand for the distribution of matter in the spacetimes, the symmetries of energy momentum tensor or MCs provides conservation laws on matter field. Throughout this paper, these collineations are discussed by vanishing Lie derivative of RICCI and energy momentum tensors respectively. Complete solution of the RCs and MCs equations, which are formed in the result of vanishing Lie derivative are explored. Studying all these collineations in the said spacetime, it has been shown that RCs of the spacetime form an infinite dimensional vector space where as MCs are Killing vector fields. (author)

    It has already been shown that the gravitational waves emitted from a Schwarzschild black hole in f(R) gravity have no signatures of the modification of gravity from General Relativity, as the Regge-Wheeler equation remains invariant. In this paper we consider the perturbations of Ricci scalar in a vacuum Schwarzschild spacetime, which is unique to higher order theories of gravity and is absent in General Relativity. We show that the equation that governs these perturbations can be reduced to a Volterra integral equation. We explicitly calculate the reflection coefficients for the Ricci scalar perturbations, when they are scattered by the black hole potential barrier. Our analysis shows that a larger fraction of these Ricci scalar waves are reflected compared to the gravitational waves. This may provide a novel observational signature for fourth order gravity.

This comparative list can easily be extended to cover the classification in tetrad language of any second-order, trace-free, symmetric tensor in a space-time. A fourth-order tensor which is the product of two such tensors was defined by Plebanski and used in his classification. This has the same symmetries as the Weyl tensor. The Petrov classification of this tensor, here called the Plebanski tensor, is discussed along with the classification of the Ricci tensor. The use of the Plebanski tensor in a couple of areas of general relativity is also briefly discussed

  11. Ricci time in the Lemaître-Tolman model and the block universe

    It is common to think of our universe according to the "block universe" concept, which says that spacetime consists of many "stacked" three-surfaces, labelled by some kind of proper time, . Standard ideas do not distinguish past and future, but Ellis' "evolving block universe" tries to make a fundamental distinction. One proposal for this proper time is the proper time measured along the timelike Ricci eigenlines, starting from the big bang. This work investigates the shape of the "Ricci time" surfaces relative to the the null surfaces. We use the Lemaître-Tolman metric as our inhomogeneous spacetime model, and we find the necessary and sufficient conditions for these constant surfaces, , to be spacelike or timelike. Furthermore, we look at the effect of strong gravity domains by determining the location of timelike S regions relative to apparent horizons. We find that constant Ricci time surfaces are always spacelike near the big bang, while at late times (near the crunch or the extreme far future), they are only timelike under special circumstances. At intermediate times, timelike S regions are common unless the variation of the bang time is restricted. The regions where these surfaces become timelike are often adjacent to apparent horizons, but always outside them, and in particular timelike S regions do not occur inside the horizons of black-hole-like models.

    Full Text Available the present article aims at reconstructing Robert Nozick’s cen-tral arguments about the extreme positions held by North American li-bertarians who do not distinguish between Welfare state and totalitarian state. Despite divergences on a pivotal question, that of the state, there are some affinities between Nozick and this current of thought. Contrary to the anarchist theory, the Minimal state is preferable to the state of nature as described by John locke.O presente artigo tem como objetivo reconstruir argumentos cen-trais, desenvolvidos por Robert Nozick, acerca das posições extremas que não diferenciam Estado-providência e Estado totalitário na política dos libertarianos norte-americanos, isto é, sobre as afinidades percebidas por Nozick com as teses desta corrente de pensamento, embora se afastando num ponto essencial: a questão do Estado. Ao contrário da teoria anar-quista, o Estado mínimo é preferível ao estado de natureza, tal como John locke o descreve.

    A severely growth retarded baby was born at 38 weeks gestation. He had multiple craniofacial anomalies, microbrachycephaly, phocomelia in the upper limbs and renal cysts visible on ultrasound. He died of recurrent apneas. The autopsy showed left sided multicystic dysplastic kidney and absence of one testis. Cytogenetic studies did not reveal any abnormality. The phenotypic features match those described in the Roberts-SC phocomelia syndrome. A literature review revealed that 50% of these patients have chromosomal defects and antenatal detection is possible on ultrasound and by chromosome analysis of the amniocytes.

    Robert Hooke was a polymath whose expertise during the 17th century spanned many different scientific areas. As a schoolboy on the Isle of Wight he was obsessed with the possibility of human flight and later became equally absorbed in cosmology and planetary motion. His skills as an artist were put to good use both as an architect following the Great Fire of London and before that in Micrographia. Although that book is best known for demonstrating the power of Hooke's microscope, Micrographia describes distant planetary bodies, the wave theory of light, the organic origin of fossils, and various other philosophical and scientific interests of its author The following thumbnail sketches of Hooke reveal him to be a man of enormous energy and imagination whose ideas were often pirated or under-rated.

    Various descriptions of what would now be called Korsakoff Syndrome may be found in the medical literature predating the eponymous reports of Sergei Korsakoff (1854-1900) that date from 1887 onwards. Of these, it has been stated that the "most promising account" (Draaisma in Disturbances of the mind 163-164, 2009) may be that of Dr. Robert Lawson, published in 1878 in the journal Brain in its inaugural year of publication (Lawson in Brain 1:182-194, 1878). As Lawson is likely to be an unfamiliar name to most neurologists, and does not appear in the Oxford Dictionary of National Biography, we offer this brief account of his life and work.

    We make a scalar representation of interactive models with cold dark matter and modified holographic Ricci dark energy through unified models driven by scalar fields with non-canonical kinetic term. These models are applications of the formalism of exotic k-essences generated by the global description of cosmological models with two interactive fluids in the dark sector and in these cases they correspond to the usual k-essences. The formalism is applied to the cases of constant potential in Friedmann-Robertson-Walker geometries. (orig.)

    A special class of higher curvature theories of gravity, Ricci cubic gravity (RCG), in general d dimensional space-time has been investigated in this paper. We have used two different approaches, the linearized equations of motion and the auxiliary field formalism to study the massive and massless graviton propagating modes of the AdS background. Using the auxiliary field formalism, we have found the renormalized boundary stress tensor to compute the mass of the Schwarzschild-AdS and Lifshitz black holes in RCG theory. (orig.)

    2018-04-01

    We provide a complete classification of static plane symmetric space-times according to conformal Ricci collineations (CRCs) and conformal matter collineations (CMCs) in both the degenerate and nondegenerate cases. In the case of a nondegenerate Ricci tensor, we find a general form of the vector field generating CRCs in terms of unknown functions of t and x subject to some integrability conditions. We then solve the integrability conditions in different cases depending upon the nature of the Ricci tensor and conclude that the static plane symmetric space-times have a 7-, 10- or 15-dimensional Lie algebra of CRCs. Moreover, we find that these space-times admit an infinite number of CRCs if the Ricci tensor is degenerate. We use a similar procedure to study CMCs in the case of a degenerate or nondegenerate matter tensor. We obtain the exact form of some static plane symmetric space-time metrics that admit nontrivial CRCs and CMCs. Finally, we present some physical applications of our obtained results by considering a perfect fluid as a source of the energy-momentum tensor.

    The objective of this paper is to discuss the Chameleon Brans–Dicke gravity with non-minimally matter coupling of scalar field. We take modified Holographic Ricci dark energy model in this gravity with its energy density in interaction with energy density of cold dark matter. We assume power-law ansatz for scale factor and scalar field to discuss potential as well as coupling functions in the evolving universe. These reconstructed functions are plotted versus scalar field and time for different values of power component of scale factor n. We observe that potential and coupling functions represent increasing behavior, in particular, consistent results for a specific value of n. Finally, we have examined validity of the generalized second law of thermodynamics and we have observed its validity for all values of n. (paper)

    2013-11-01

    Full Text Available We demonstrate how a combination of our recently developed methods of partner symmetries, symmetry reduction in group parameters and a new version of the group foliation method can produce noninvariant solutions of complex Monge-Ampère equation (CMA and provide a lift from invariant solutions of CMA satisfying Boyer-Finley equation to non-invariant ones. Applying these methods, we obtain a new noninvariant solution of CMA and the corresponding Ricci-flat anti-self-dual Einstein-Kähler metric with Euclidean signature without Killing vectors, together with Riemannian curvature two-forms. There are no singularities of the metric and curvature in a bounded domain if we avoid very special choices of arbitrary functions of a single variable in our solution. This metric does not describe gravitational instantons because the curvature is not concentrated in a bounded domain.

Tchrakian, Phys. Lett. B 644 (2007) 370, (hep-th/0611077)] is rederived using the Fefferman-Graham (d+2)-dimensional ambient space approach. The corresponding mysterious 'holographic' structure of these operators is clarified. We explore also the (d+2)-dimensional ambient space origin of the Ricci gauging procedure proposed by A. Iorio, L. O'Raifeartaigh, I. Sachs and C. Wiesendanger as another method of constructing the Weyl invariant Lagrangians. The corresponding gauged ambient metric, Fefferman-Graham expansion and extended Penrose-Brown-Henneaux transformations are proposed and analyzed

    In this paper, two modified Ricci models are considered as the candidates of unified dark matter-dark energy. In model one, the energy density is given by ρ MR =3M pl (αH 2 + βH), whereas, in model two, by ρ MR =3M pl ((α)/(6)R + γH H -1 ). We find that they can explain both dark matter and dark energy successfully. A constant equation of state of dark energy is obtained in model one, which means that it gives the same background evolution as the wCDM model, while model two can give an evolutionary equation of state of dark energy with the phantom divide line crossing in the near past.

    In this work we study the dark energy problem by adopting an holographic model proposed recently in the literature. In this model there has been postulated an energy density {rho}{proportional_to}R, where R is the Ricci scalar curvature. Under this consideration, we have obtained a cosmological scenario which arises from considering two non-interacting fluids along the lines of a reasonable Ansatz for the cosmic coincidence parameter. We have adjusted the involved parameters in the model according to the observational data, showing that the equation of state for the dark energy exhibits a cross through the -1 barrier. Additionally, we have found a disagreement of these parameters in comparison with a scalar field theory approach. (orig.)

  16. Emergent Criticality and Ricci Flow in a 2D Frustrated Heisenberg Model

    Orth, Peter P.

    2014-03-01

    In most systems that exhibit order at low temperatures, the order occurs in the elementary degrees of freedom such as spin or charge. Prominent examples are magnetic or superconducting states of matter. In contrast, emergent order describes the phenomenon where composite objects exhibit longer range correlations. Such emergent order has been suspected to occur in a range of correlated materials. One specific example are spin systems with competing interactions, where long-range discrete order in the relative orientation of spins may occur. Interestingly, this order parameter may induce other phase transitions as is the case for the nematic transition in the iron pnictides. In this talk, we introduce and discuss a system with emergent Z6 symmetry, a two-dimensional frustrated Heisenberg antiferromagnet on the windmill lattice consisting of interpenetrating honeycomb and triangular lattices. The multiple spin stiffnesses can be captured in terms of a four-dimensional metric tensor, and the renormalization group flow of the stiffnesses is described by the Ricci flow of the metric tensor. The key result is a decoupling of an emergent collective degree of freedom given by the relative phase of spins on different sublattices. In particular, our results reveal a sequence of two Berezinskii-Kosterlitz-Thouless phase transitions that bracket a critical phase.

  17. Israel-Stewart Approach to Viscous Dissipative Extended Holographic Ricci Dark Energy Dominated Universe

    Directory of Open Access Journals (Sweden)

    Surajit Chattopadhyay

    2016-01-01

    Full Text Available This paper reports a study on the truncated Israel-Stewart formalism for bulk viscosity using the extended holographic Ricci dark energy (EHRDE. Under the consideration that the universe is dominated by EHRDE, the evolution equation for the bulk viscous pressure Π in the framework of the truncated Israel-Stewart theory has been taken as τΠ˙+Π=-3ξH, where τ is the relaxation time and ξ is the bulk viscosity coefficient. Considering effective pressure as a sum of thermodynamic pressure of EHRDE and bulk viscous pressure, it has been observed that under the influence of bulk viscosity the EoS parameter wDE is behaving like phantom, that is, wDE≤-1. It has been observed that the magnitude of the effective pressure peff=p+Π is decaying with time. We also investigated the case for a specific choice of scale factor; namely, a(t=(t-t0β/(1-α. For this choice we have observed that a transition from quintessence to phantom is possible for the equation of state parameter. However, the ΛCDM phase is not attainable by the state-finder trajectories for this choice. Finally it has been observed that in both of the cases the generalized second law of thermodynamics is valid for the viscous EHRDE dominated universe enveloped by the apparent horizon.

    The background cosmological dynamics of the late Universe is analysed on the framework of a dark energy model described by an holographic Ricci dark energy component. Several kind of interactions between the dark energy and the dark matter components are considered herein. We solve the background cosmological dynamics for the different choices of interactions with the aim to analyse not only the current evolution of the universe but also its asymptotic behaviour and, in particular, possible future singularities removal. We show that in most of the cases, the Big Rip singularity, a finger print of this model in absence of an interaction between the dark sectors, is substituted by a de Sitter or a Minkowski state. Most importantly, we found two new future bouncing solutions leading to two possible asymptotic behaviours, we named Little Bang and Little Sibling of the Big Bang. At a Little Bang, as the size of the universe shrinks to zero in an infinite cosmic time, the Hubble rate and its cosmic time derivative blow up. In addition, at a Little sibling of the Big Bang, as the size of the universe shrinks to zero in an infinite cosmic time, the Hubble rate blows up but its cosmic time derivative is finite. These two abrupt events can happen as well in the past.

    In this work, we studied the Power Law and the Logarithmic Entropy Corrected versions of the Ricci Dark Energy (RDE) model in a spatially non-flat universe and in the framework of Hořava-Lifshitz cosmology. For the two cases containing non-interacting and interacting RDE and Dark Matter (DM), we obtained the exact differential equation that determines the evolutionary form of the RDE energy density. Moreover, we obtained the expressions of the deceleration parameter q and, using a parametrization of the equation of state (EoS) parameter ω D given by the relation ω D ( z) = ω 0+ ω 1 z, we derived the expressions of both ω 0 and ω 1. We interestingly found that the expression of ω 0 is the same for both non-interacting and interacting case. The expression of ω 1 for the interacting case has strong dependence from the interacting parameter b 2. The parameters derived in this work are done in small redshift approximation and for low redshift expansion of the EoS parameter.

    Roberts syndrome is a rare disease, with multiple limb and skeletal abnormalities (called "pseudothalidomide disease"). There are only around 150 cases described in literature. We present a case of Roberts syndrome, diagnosed in moment of delivery, after a pregnancy without prenatal follow-up. The stillborn baby was naturally delivered by a 17-year-old primiparous woman at 38 weeks of amenorrhea. The pregnancy was not followed due to socioeconomic and family situation, and no prenatal ultrasound was performed. The male baby has 2650 g and presented several morphological abnormalities and tight double umbilical abdominal loop. The macroscopic evaluation showed: dolichocephaly, hypoplastic inferior maxilla with micrognathia, antimongoloid palpebral slant, pterygium colli, abnormal and lower implanted ears, superior limbs phocomelia, syndactyly at lower left limb and tetradactyly in all limbs, bilateral cryptorchidism, pancreatic aplasia. Roberts syndrome is a rare genetic disease with recessive autosomal transmission generated by mutations in ESCO2 gene, located on chromosome 8. The disease should be easy to diagnose by antenatal ultrasound examination, but in our case, the lack of prenatal follow-up determined the diagnostic at term. We believe consider this case is an argument towards introducing ultrasound-screening compulsory to all pregnancies. To identify a possible genetic mutation, further investigations of the parents are in progress, but classically the disease has a recessive autosomal transmission.

    Thus far, there seem to be no complete criteria that can settle the issue as to what the correct generalization of the Dirac-Born-Infeld (DBI) action, describing the low-energy dynamics of the D-branes, to the non-Abelian case would be. According to recent suggestions, one might pass the issue of worldvolume solitons from an Abelian to non-Abelian setting by considering the stack of multiple, coincident D-branes and use it as a guideline to construct or censor the relevant non-Abelian version of the DBI action. In this spirit, here we are interested in the explicit construction of SU(2) Yang-Mills (YM) instanton solutions in the background geometry of two coincident probe D4-brane worldspaces, particularly when the metric of the target spacetime in which the probe branes are embedded is given by the Ricci-flat, magnetic extremal 4-brane solution in type IIA supergravity theory with its worldspace metric being given by that of TaubendashNewman-Unti-Tamburino (NUT) and Eguchi-Hanson solutions, the two best-known gravitational instantons. Then we demonstrate that, with this YM instanton-gravitational instanton configuration on the probe D4-brane worldvolume, the energy of the probe branes attains its minimum value and hence enjoys a stable state provided one employs Tseytlin's non-Abelian DBI action for the description of multiple probe D-branes. In this way, we support the arguments in the literature in favor of Tseytlin's proposal for the non-Abelian DBI action

  6. Studying ventricular abnormalities in mild cognitive impairment with hyperbolic Ricci flow and tensor-based morphometry.

    Mild Cognitive Impairment (MCI) is a transitional stage between normal aging and dementia and people with MCI are at high risk of progression to dementia. MCI is attracting increasing attention, as it offers an opportunity to target the disease process during an early symptomatic stage. Structural magnetic resonance imaging (MRI) measures have been the mainstay of Alzheimer's disease (AD) imaging research, however, ventricular morphometry analysis remains challenging because of its complicated topological structure. Here we describe a novel ventricular morphometry system based on the hyperbolic Ricci flow method and tensor-based morphometry (TBM) statistics. Unlike prior ventricular surface parameterization methods, hyperbolic conformal parameterization is angle-preserving and does not have any singularities. Our system generates a one-to-one diffeomorphic mapping between ventricular surfaces with consistent boundary matching conditions. The TBM statistics encode a great deal of surface deformation information that could be inaccessible or overlooked by other methods. We applied our system to the baseline MRI scans of a set of MCI subjects from the Alzheimer's Disease Neuroimaging Initiative (ADNI: 71 MCI converters vs. 62 MCI stable). Although the combined ventricular area and volume features did not differ between the two groups, our fine-grained surface analysis revealed significant differences in the ventricular regions close to the temporal lobe and posterior cingulate, structures that are affected early in AD. Significant correlations were also detected between ventricular morphometry, neuropsychological measures, and a previously described imaging index based on fluorodeoxyglucose positron emission tomography (FDG-PET) scans. This novel ventricular morphometry method may offer a new and more sensitive approach to study preclinical and early symptomatic stage AD. Copyright © 2014 Elsevier Inc. All rights reserved.

Phantastic genre cinema is very rare in contemporary Germany—especially in the 1980s, the time when Italian horror reached another peak with Dario Argento's Opera (1985). The cliché of the German "easy comedy" ruled mainstream film production at the time, and so it appeared a kind of miracle when 27-year-old writer/direct...

    2013-01-15

    We examine a Friedmann-Robertson-Walker universe filled with interacting dark matter, modified holographic Ricci dark energy (MHRDE), and a decoupled baryonic component. The estimations of the cosmic parameters with Hubble data lead to an age of the universe of 13.17 Gyr and show that the MHRDE is free from the cosmic-age problem at low redshift (0{<=}z{<=}2) in contrast to holographic Ricci dark energy (HRDE) case. We constrain the parameters with the Union2 data set and contrast with the Hubble data. We also study the behavior of dark energy at early times by taking into account the severe bounds found at recombination era and/or at big bang nucleosynthesis. The inclusion of a non-interacting baryonic matter forces that the amount of dark energy at z{sub t} {proportional_to} O(1) changes abruptly implying that {Omega} {sub x} (z {approx_equal}1100)=0.03, so the bounds reported by the forecast of Planck and CMBPol experiments are more favored for the MHRDE model than in the case of HRDE cutoff. For the former model, we also find that at high redshift the fraction of dark energy varies from 0.006 to 0.002, then the amount of {Omega} {sub x} at the big bang nucleosynthesis era does not disturb the observed helium abundance in the universe provided that the bound {Omega} {sub x} (z {approx_equal}10 {sup 10}) <0.21 is hold.

    He called the first atomic bomb “technically sweet,” yet as he watched its brilliant light explode over the New Mexico desert in 1945 in advance of the black horrors of Hiroshima and Nagasaki, he also thought of the line from the Hindu epic The Bhagavad Gita: “I am become Death, the destroyer of worlds.” Physicist J. Robert Oppenheimer, the scientific director of the Manhattan Project, the single most recognizable face of the atomic bomb, and a man whose name has become almost synonymous with Cold War American nuclear science, was and still is a conflicted, controversial figure who has come to represent an equally ambivalent technology. The Meanings of J. Robert Oppenheimer examines how he has been represented over the past seven decades in biographies, histories, fiction, comics, photographs, film, television, documentaries, theater, and museums.

  15. Color and Contingency in Robert Boyle's Works.

    Baker, Tawrin

    2015-01-01

    This essay investigates the relationship between color and contingency in Robert Boyle's Experiments and Considerations Touching Colours (1664) and his essays on the unsuccessfulness of experiments in Certain Physiological Essays (1661). In these two works Boyle wrestles with a difficult practical and philosophical problem with experiments, which he calls the problem of contingency. In Touching Colours, the problem of contingency is magnified by the much-debated issue of whether color had any deep epistemic importance. His limited theoretical principle guiding him in Touching Colours, that color is but modified light, further exacerbated the problem. Rather than theory, Boyle often relied on craftsmen, whose mastery of color phenomena was, Boyle mentions, brought about by economic forces, to determine when colors were indicators of important 'inward' properties of substances, and thus to secure a solid foundation for his experimental history of color.

    The Wood's lamp aids in the diagnosis of multiple infectious, inflammatory and neoplastic dermatologic conditions. Although the Wood's lamp has many applications, which have improved both the diagnosis and management of disease, the man credited for its invention is relatively unknown in medicine. Robert Williams Wood, a prominent physicist of the early 20th century, is credited for the invention of the Wood's lamp. Wood was the father of infrared and ultraviolet photography and made significant contributions to other areas in optics and spectroscopy. Wood's work encompassed the formative years of American Physics; he published over 200 original papers over his lifetime. A few years after the invention of the Wood's lamp for ultraviolet photography, physicians in Europe adopted the Wood's lamp for dermatologic applications. Wood's lamp remains popular in clinics globally, given its ease of use and ability to improve diagnostic precision. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    2004-01-01

    Robert Oppenheimer has become the symbol of the scientist tormented and anguished by the consequences of his discoveries. R.Oppenheimer took a major part in the Manhattan project for the designing of the first atomic bomb. During this period he considered the thermonuclear bomb as the next step to reach but after Japan's surrender he reconsidered his position and favoured a more moderate atomic policy. R.Oppenheimer began to militate in favour of an international control of nuclear energy and wanted that Usa relinquish to design the hydrogen bomb. In 1953 in full Mac-Carthysm era, he was accused of being a communist and of spying for Ussr and as a consequence he was deprived of his office in AEC (atomic energy committee) but in 1963 president Lyndon Johnson rehabilitated him and R.Oppenheimer was awarded the highest reward of AEC: the Enrico Fermi prize.

    Robert H. Koch, emeritus professor of astronomy and astrophysics at the University of Pennsylvania, passed away at his home in Ardmore, Pennsylvania on 11 October 2010 after a brief illness. Bob was 80 years old and remained sharp and intellectually engaged with the astronomical community up until the onset of complications from a brain tumor. Bob was born in York, Pennsylvania on 19 December 1929, and graduated from York Catholic High School in 1947. He attended the University of Pennsylvania on a senatorial scholarship, graduating in 1951. After two years in the United States Army, he enrolled in graduate school at the University of Pennsylvania, doing his doctoral research on the photoelectric photometry of R CMa, AO Cas, AS Eri, and XY Leo at the Steward Observatory, University of Arizona in Tucson. Bob would continue this exploration of close binary stars, their atmospheres and interactions, for the rest of his career. Bob met his future spouse, Joanne C. Underwood, while in graduate school in 1957 and they were married in 1959. Bob received his PhD in astronomy in 1959 and moved to Amherst, Massachusetts, where he taught as a member of the Four College Astronomy Department until 1966. Following a year at the University of New Mexico in Albuquerque, Bob joined the Astronomy Department at Penn, teaching and doing research there until his retirement in 1996. Bob's main interests were the study of close and eclipsing binary stars, stellar envelopes and winds, intrinsic variables, transits and occultations, and the Milky Way Galaxy, producing well over 100 refereed publications. Bob was partial to photoelectric photometry and polarimetry, conducting most of his observational research at the University of Pennsylvania Flower and Cook Observatory, and at other ground- and space-based observatories. As an international figure in the area of binary stars, Bob had widespread collaborations with scientists at other institutions, in the US and throughout the world, and

    Full Text Available Resumen Los discursos cruzados son el soporte común del presente número de Cuadernos. El cruce que planteamos tiene como protagonistas al artista Robert Smithson y a los arquitectos Adam Caruso y Peter St John. Estos últimos hacen mención del trabajo del artista norteamericano para explicar su proyecto de remodelación de Stortorget, la plaza de la catedral en el centro de Kalmar, Suecia. A partir de aquí, comenzamos una exploración del trabajo y las preocupaciones de ambos que nos permite dibujar convergencias y sintonías procesuales por encima de las diferencias temáticas, ideológicas y estilísticas. Al disponer en paralelo la obra de Smithson y Caruso St John descubrimos vibraciones y resonancias que muestran una interacción productiva de sus preocupaciones. La materia se convierte en sus propuestas en un objeto activo y sensible, un depósito energético con el que operar. El traslado de piedras en Stortorget convoca la memoria de la ciudad del mismo modo que el basalto y la sal del Spiral Jetty, erosionados por el tiempo, nos hablan de procesos abiertos. El tiempo y la memoria pasan a ser soportes estratégicos con los que construyen sus miradas. Los objetos se disuelven en las relaciones que establecen con su entorno produciendo equilibrios frágiles e instantáneos. De esta manera el artículo pretende generar un vórtice de reflexión, una espiral en cuyo recorrido se manifiesten las tensiones parciales del cruce propuesto, sus fijezas momentáneas.

    2004-12-01

    Robert M. Walker, PhD, Professor of Physics in Arts & Sciences and a faculty fellow of the McDonnell Center for the Space Sciences, died of stomach cancer Thursday, 12 February 2004, in Brussels, Belgium. He was 75. Walker worked on the frontiers of space research for more than four decades. Robert Walker was born in Philadelphia on 6 February 1929. His mother was Dorothy Potter and he considered Roger Potter his father though he was not his biological father. His early years were spent in New York City and in upstate New York. He attended the Bronx High School of Science, earned his BS in physics from Union College and in 1954, he received his PhD in particle physics from Yale University. He subsequently joined the General Electric Laboratory in Schenectady, New York where he studied the radiation effects in solids. His work on defects in irradiated copper is still regarded as the definitive work on the topic. In the early 1960s, Walker's discovery of fossil nuclear particle tracks in minerals was instrumental to new developments in geo-chronology and cosmic ray physics. In particular, his discovery of tracks from nuclei heavier than iron opened a new frontier of cosmic ray physics. He subsequently pioneered the use of plastics to detect and count such nuclei in cosmic ray balloon flights. Beginning in 1966, when he moved to Washington University and became the first McDonnell Professor of Physics, his research interests turned more toward space physics. He was the inaugural director of the McDonnell Center, which was established in 1975 by a gift from aerospace pioneer James S. McDonnell. Walker was a member of the NASA committee that allocated samples of the first returned lunar materials, and his laboratory led the way in deciphering their record of lunar, solar system and galactic evolution. Together with Ghislaine Crozaz and other colleagues, Walker made path breaking laboratory studies of the first moon rocks revealing the history of solar radiation and

  16. Robert Lowell’s Culturally Coded Lexis

    Directory of Open Access Journals (Sweden)

    Lidija Davidovska

    2014-12-01

    Full Text Available In this paper, I will examine how a vital ele­ment of Robert Lowell’s descriptive and narrative struc­tures, i.e., the lexis, promise to unfold the “layers” of the culture that served as context for Life Studies. This in­volves exploring both the denotations and connotations of his culturally encoded lexis, that is, the external mean­ings of certain words and phrases before they “en­ter” the poem and the internal meanings they acquire after entering the poem. This process of “verbal osmo­sis”, when words absorb meaning from these different contexts, is, what I believe, critic and linguist Winifred Nowottny describes as “give and take between those patterns” (Fowler, 2009: 31. My analysis will focus on the sociolinguistic patina accrued on certain units of Lowell’s poetic lexis, such as names of historical people, events and concepts belonging to American and Euro­pean spiritual cultures and traditions, as well as brand names from popular material culture of the first half of the twentieth century. The analysis will also dwell on the use of idioms, catch phrases and other verbal clichés which reflect the culture that generated them. They func­tion as verbal “ready-mades” that additionally rein­force Lowell’s well-known anecdotal, colloquial and infor­mal poetic language. The choice of these particular lexical items is significant as they reflect the categoriza­tion of the world and the experience of the poetic voice or the “language user” in broader linguistic terms. At the same time, the categorization of the experience reflects the ideational position, the worldview of the language user. In the context of his poetics of immanence and experi­ence, this culturally coded poetic diction is ana­lyzed as another authentic and documented presenta­tion of immanent narrator’s “lived experience”.

Kurz darauf starben in Hiroshima und Nagasaki mehr als 200 000 Menschen durch die neue ''Wunderwaffe'' - die Menschheit war ins Atomzeitalter eingetreten. Erschuettert von der Zerstoerungskraft seiner Schoepfung, engagierte sich Oppenheimer fortan gegen den Einsatz nuklearer Waffen. Das machte ihn im Amerika der McCarthy-Aera verdaechtig. Er geriet ins Visier des FBI, wurde als Spion der Sowjetunion verleumdet und musste den Staatsdienst quittieren. Sein Privatleben wurde an die Oeffentlichkeit gezerrt, seine Wohnung verwanzt, sein Telefon abgehoert. Erst 1963 rehabilitierte ihn Praesident Kennedy. Ueber dreissig Jahre hinweg haben die Autoren Interviews mit Oppenheimers Angehoerigen, Freunden und Kollegen gefuehrt, FBI-Akten gesichtet, Tonbaender von Reden und Verhoeren

    Robert Oppenheimer has become the symbol of the scientist tormented and anguished by the consequences of his discoveries. R.Oppenheimer took a major part in the Manhattan project for the designing of the first atomic bomb. During this period he considered the thermonuclear bomb as the next step to reach but after Japan's surrender he reconsidered his position and favoured a more moderate atomic policy. R.Oppenheimer began to militate in favour of an international control of nuclear energy and wanted that Usa relinquish to design the hydrogen bomb. In 1953 in full Mac-Carthysm era, he was accused of being a communist and of spying for Ussr and as a consequence he was deprived of his office in AEC (atomic energy committee) but in 1963 president Lyndon Johnson rehabilitated him and R.Oppenheimer was awarded the highest reward of AEC: the Enrico Fermi prize.

  19. Kaluza-Klein Multidimensional Models with Ricci-Flat Internal Spaces: The Absence of the KK Particles

    Directory of Open Access Journals (Sweden)

    Alexey Chopovsky

    2013-01-01

    Full Text Available We consider a multidimensional Kaluza-Klein (KK model with a Ricci-flat internal space, for example, a Calabi-Yau manifold. We perturb this background metrics by a system of gravitating masses, for example, astrophysical objects such as our Sun. We suppose that these masses are pressureless in the external space but they have relativistic pressure in the internal space. We show that metric perturbations do not depend on coordinates of the internal space and gravitating masses should be uniformly smeared over the internal space. This means, first, that KK modes corresponding to the metric fluctuations are absent and, second, particles should be only in the ground quantum state with respect to the internal space. In our opinion, these results look very unnatural. According to statistical physics, any nonzero temperature should result in fluctuations, that is, in KK modes. We also get formulae for the metric correction terms which enable us to calculate the gravitational tests: the deflection of light, the time-delay of the radar echoes, and the perihelion advance.

  20. Holographic Ricci dark energy in Randall-Sundrum braneworld: Avoidance of big rip and steady state future

    International Nuclear Information System (INIS)

    Feng Chaojun; Zhang Xin

    2009-01-01

    In the holographic Ricci dark energy (RDE) model, the parameter α plays an important role in determining the evolutionary behavior of the dark energy. When α<1/2, the RDE will exhibit a quintom feature, i.e., the equation of state of dark energy will evolve across the cosmological constant boundary w=-1. Observations show that the parameter α is indeed smaller than 1/2, so the late-time evolution of RDE will be really like a phantom energy. Therefore, it seems that the big rip is inevitable in this model. On the other hand, the big rip is actually inconsistent with the theoretical framework of the holographic model of dark energy. To avoid the big rip, we appeal to the extra dimension physics. In this Letter, we investigate the cosmological evolution of the RDE in the braneworld cosmology. It is of interest to find that for the far future evolution of RDE in a Randall-Sundrum braneworld, there is an attractor solution where the steady state (de Sitter) finale occurs, in stead of the big rip.

    Science.gov (United States)

    Surrounded by his loving family, Robert Charles Bless died at home on November 29th, three days before his 88th birthday. He was born in Ithaca, NY on Dec. 3, 1927 to a Russian father, Arthur Aaron Bless, and a French mother, Eva Chantrell Bless. Bob spent many summers on the family farm in the South of France, where he gained a great pride and joy in his French heritage, large extended family, and mother tongue. As a child growing up in Gainesville, FL, Bob's first job was snake wrangling, earning 10 cents per foot, with an added bonus for the more venomous species. Young Robbie took daily adventures in the Florida woods and swamps, armed only with pockets full of pecans and oranges. He enjoyed spending time at the family's lake cabin, where he learned to sail and helped his father plant acres of trees to grow their timber plantation. As a first generation immigrant, Bob's father received a PhD in physics, which inspired Bob to pursue an extensive educational route in astrophysics. Bob excelled in academics, graduating high school at the age of 16 and the University of Florida (B.Sc.) at 19. His path to graduate school was interrupted by a diagnosis of tuberculosis that forced him into a Florida sanitorium for one year. During this time, Bob made the most of what he described as the most dismal part of life by advocating for patient rights, initiating an inter-sanitorium newsletter, and gaining skills and experience in community organization and leadership - qualities that would later inform his leadership in academe. After being one of the first successfully treated tuberculosis patients in the US, Bob went on to earn a M.Sc. from Cornell University, and received his PhD degree in Astronomy from the University of Michigan in 1958. That same year, Bob joined the staff of the Astronomy Department of the University of Wisconsin (UW), Madison. It was there that Bob met Diane McQueen.

    2009-01-01

    It is with great sadness that I report the passing of Peter Robert Wilson, a well-known and well-loved figure in the solar physics community. Peter was on the faculty of the Department of Applied Mathematics at the University of Sydney for 39 years, and Chair of the department for 24 of these years. He was the author or co-author of more than 80 scientific research papers and a book, Solar and Stellar Activity Cycles (1994), published by Cambridge University Press. He died suddenly of a heart attack, at his home in Glebe, Australia, in the early morning of 11 November 2007. Peter was an organizer of, and participant in, many international conferences and workshops. He traveled extensively, holding visiting appointments at the University of Colorado (JILA), at Cambridge University, at the College de France (Paris), and at the California Institute of Technology [CalTech]. Most of his work was in the field of solar physics, but he also did some work on the philosophy of science and on tides. Peter came from a line of mathematicians. His father, Robert Wilson, immigrated to Australia from Glasgow in 1911, and became a mathematics teacher at Scotch College, a private school in Melbourne. There his name was changed to 'Bill' because 'Bob' was already taken." Peter's enjoyment of this story as characteristic of Australian academia (as any fan of Monty Python would understand) is indicative of his infectious sense of humor. In a similar vein, he claimed ancestry traced back to the eighteenth-century Scottish mathematician Alexander Wilson, Professor of Astronomy at the University of Glasgow. That Wilson is famous in the solar physics community for his discovery, known as the "Wilson Effect," of the photospheric depressions associated with sunspots. Peter himself could not resist writing a paper on this subject, and was delighted when the bait was taken by some less-informed colleagues who chided him for "naming an effect after himself." "Bill" Wilson married Naomi

    Boyce, Peter Bradford; Saffell, Mary E.

    2003-12-01

    Robert Fleischer was born 20 August 1918 to Leon and Rose Fleischer in Flushing, NY. He was educated at Harvard, receiving his BS in 1940, MA in 1947, and PhD in 1949. He specialized in geophysics and solar-terrestrial relations. Fleischer joined the faculty at Rensselaer Polytechnic Institute advancing from Assistant to Full professor in 1958. As Director of the RPI Observatory, Fleischer attempted to bring modern astronomy to the institutions in the Albany area by procuring the funds to build a radio telescope. He left for the National Science Foundation (NSF) before the observatory was completed. It is a testament to his character that without his enormous energy, organizational, and fundraising abilities, the radio telescope project languished after he left. Fleischer joined the NSF in 1962 as the Program Director for Solar-Terrestrial Research. He was the government-wide Coordinator for the International Quiet Sun Years, and coordinated the 1966 South American Eclipse expeditions. Thereafter, he was appointed Deputy Head of the Office of International Science Activities. Fleischer is most notably remembered as the head of the Astronomy Section at the National Science Foundation. He brought astronomy into its own at NSF and involved the community in a major way through use of advisory committees. He was dedicated to helping the astronomical community understand the funding system, the political environment, and the various factors in how money is allocated. Fleischer truly believed in the concept that scientists should be making the important decisions about their field. He was instrumental in injecting science into the oversight of the National Observatories. Relations with the community say a lot about the man, the complexities of his character, and the forces that drove him. Fleischer was passionate in his beliefs and in his devotion to doing the best for astronomy. His strong approach and belief in himself served him well in many ways, but caused him grief

  4. Roberts 22: a bipolar nebula with OH emission

    International Nuclear Information System (INIS)

    1980-01-01

    Roberts 22 is a bipolar reflection nebula illuminated by a hidden A2 Ie star. Most of its energy is radiated at infrared wavelengths. It also shows strong OH maser emission (OH 284.18 - 0.79) on the 1612 and 1665 MHz transitions, generally similar to the masers associated with M stars having infrared excesses. But the system contains no late-type star. This remarkable assemblage of attributes makes Roberts 22 unique; however, it is probably a key member of the newly-recognized population of bipolar nebulae. From an analysis of the properties of Roberts 22 some published interpretations of other bipolar nebulae are questioned, in particular the derivation of spectral types for their underlying stars by the assumption of photo-ionization of the gas, and their evolutionary description as proto-planetary nebulae.

    Robert Bourassa's contributions to the hydroelectric development at James Bay were acknowledged with the inauguration of a park in the ex-prime minister's name. Phase 1 of the James Bay hydroelectric project constituted the world's biggest construction site, employing more than 180,000 people from beginning to project completion. The James Bay project allowed Hydro-Quebec to gain one of the world's largest electric power utilities and to gain significant competitive edge over its competitors. The Robert Bourassa Park contains a picnic area and a visitor interpretation centre which describes the history of the project. A sequence of 5 signposts summarize the contributions that Robert Bourassa made to the megaproject which cost over $20.6 billion. The complex consists of 65 turbines which produce 15,235 megawatts of electricity. 1 fig

  6. Double trisomy (48,XXX,+18) with features of Roberts syndrome

    We report an infant with double trisomy 48,XXX,+18, who also displayed features of Roberts syndrome. All previously published cases with similar double trisomy have presented with features of trisomy 18 syndrome. The chromosome analysis done at birth revealed the double trisomy; parental chromosomes were normal. The proband presented with microbrachycephaly, unilateral cleft lip and palate, choanal atresia, midfacial capillary hemanioma, thin nares, shallow orbits, malformed ears, sparse hair, hypomelia of the upper limbs, rocker-bottom feet, auricular septal defect and agenesis of the corpus callosum. Characteristic features of Roberts syndrome included hypomelia, midfacial defects, and severe growth deficiency. Among the many different features reported in the literature for patients with trisomy 18 syndrome, the most consistent were growth deficiency, clenched fingers and congenital heart defects (e.g. VSD, ASD, PDA). Although some of our patient`s features such as cleft lip and cleft palate, low-set malformed ears, ASD, defects of the corpus callosum, choanal atresia, radial aplasia could also be seen in trisomy 18 syndrome (in 10-50% of the cases), her phenotype was more typical of Roberts syndrome because of symmetrical hypomelia and midfacial defects. Our patient`s chromosomes did not show premature separation of centromeric heterochromatin, a feature reported to occur in approximately one-half of individuals with Roberts syndrome. Sporadic aneuploidy involving different chromosomes has been found in lymphocyte cultures from some Roberts syndrome patients and is considered by some authors as a mitotic mutant. This aneuploidy is most likely to be chromosome gain. The simultaneous occurrence of trisomy X and 18 is extremely rare with only 11 cases having been reported in the literature. Our patient is unique since she has the double trisomy in addition to the characteristic features of Roberts syndrome.

    Few astronomy communication projects are as well known or as widely disseminated as the Astronomy Picture of the Day (or APOD for short). Since its creation in 1995, it has popularised thousands of images and helped to explain the cosmos through informative captions. Impressively, the site shows no signs of slowing down and has amassed many loyal supporters. This success can be attributed to the two astronomers behind the project: Robert Nemiroff and Jerry Bonnell. CAPjournal has interviewed Robert to discover his view of APOD, and the lesser known issues that surround it.

    2018-04-09

    As a professor of chemistry at the University of Pennsylvania, Robert Hare actively shaped early American science. He participated in a large network of scholars, including Joseph Henry, François Arago, and Jacob Berzelius, and experimented with and wrote extensively about electricity and its associated chemical and thermal phenomena. In the early nineteenth century, prominent chemists such as Berzelius and Humphry Davy proclaimed that a revolution had occurred in chemistry through electrical research. Examining Robert Hare's contributions to this discourse, this paper analyzes how Hare's study of electricity and the caloric theory of heat led him to propose a new theory of galvanism. It also examines the reception of Hare's work in America and Great Britain, highlighting the contributions of early American chemists to the development of electrochemistry.

  9. Transitioning Natures: Robert Schuller’s Garden Grove Experiment

    Directory of Open Access Journals (Sweden)

    Antonio Petrov

    2016-09-01

    Full Text Available Through the lens of Evangelist Reverend Robert H. Schuller’s Garden Grove drive-in walk-in church, this paper aims to exemplify how his architecture has transcended existing geographies that have long been anchored by the epistemology of what can be referred to as traditional “religious” architecture. This paper examines how Schuller instrumentalized broader imbrications of political contexts to change or manipulate the traditional religious subject. It also presents how Robert Schuller’s Garden Grove experiment reconceptualized “territory” as an evolving ideological dimension; not as a trajectory, or as transitory space, but as inhabitable third nature. My analysis challenges established readings of religious architecture as being interiorized manifestations. To do so, it poses the following questions: how does this meta-geographical dimension shed new light on questions of (traditional architectural aesthetics in Protestant architecture? What spaces and politics does it produce? Does the third nature have a history of its own?

  13. The auriferous placer at Mount Robert, Pietersburg Greenstone belt

    1986-01-01

    The Mount Robert gold placer near Potgietersrus occurs in coarse, matrix-supported conglomerates of the Uitkyk Formation within the Pietersburg greenstone belt. Sedimentological and mineralogical investigations indicate that the conglomerates and the ore minerals were derived from a greenstone provenance, and that they were deposited in a braided river environment within a rapidly subsiding trough. Lack of sedimentological concentration of the heavy minerals is considered to be the main reason for the low and erratic gold grades encountered (usually below 1 g/t) and, thus, the failure of all past mining ventures. The mineralogical composition of the Mount Robert ore closely resembles that of the Witwatersrand deposits. However, uraninite is absent, probably as a result of its complete removal by weathering processes. Remaining small uranium concentrations can still be detected within the conglomerates where they occur associated with grains of carbonaceous matter, leucoxene aggregates, and secondary iron-hydroxides. U3O8 values found in the conglomerates are given

    The drawings of fossils by Robert Hooke and Richard Waller that were the basis of the engravings in Hooke's Posthumous works (1705) are published here for the first time. The drawings show that both Hooke and Waller were proficient draftsmen with a keen eye for the details of petrified objects. These drawings provided Hooke with a polemic edge in making the case for the organic origins of ‘figured stones’.

    Roberts syndrome and SC phocomelia syndrome are rare autosomal recessive genetic disorders representing the extremes of the spectrum of severity of the same condition, caused by mutations in ESCO2 gene. We report three new patients with Roberts syndrome from three unrelated consanguineous Egyptian families. All patients presented with growth retardation, mesomelic shortening of the limbs more in the upper than in the lower limbs and microcephaly. Patients were subjected to clinical, cytogenetic and radiologic examinations. Cytogenetic analysis showed the characteristic premature separation of centromeres and puffing of heterochromatic regions. Further, sequencing of the ESCO2 gene identified a novel mutation c.244_245dupCT (p.T83Pfs*20) in one family besides two previously reported mutations c.760_761insA (p.T254Nfs*27) and c.764_765delTT (p.F255Cfs*25). All mutations were in homozygous state, in exon 3. The severity of the mesomelic shortening of the limbs and craniofacial anomalies showed variability among patients. Interestingly, patient 1 had abnormal skin hypopigmentation. Serial fetal ultrasound examinations and measurements of long bones diagnosed two affected fetuses in two of the studied families. A literature review and case comparison was performed. In conclusion, we report a novel ESCO2 mutation and expand the clinical spectrum of Roberts syndrome. © 2015 Japanese Teratology Society.

  18. An Architecture for the Electronic Church: Oral Roberts University in Tulsa, Oklahoma.

    2016-04-01

    More than a university, Oral Roberts University in Tulsa, Oklahoma, was also the headquarters for evangelist Oral Roberts's electronic church. The electronic church in America, dominated by Christian evangelicals, used technology to spread the Gospel over radio airways and television signals to a dispersed audience. Yet evangelicals like Roberts also constructed ambitious campuses in real space and time. The architecture of Oral Roberts University visualized a modern and "populuxe" image for the electronic church in the 1960s and 1970s. The university's Prayer Tower purposely alluded to the Seattle Space Needle, aligning religion and the Space Age, and the campus's white, gold, and black color palette on late modern buildings created an image of aspirational luxury, conveying Roberts's health and wealth gospel. Oral Roberts University served as a sound stage for Roberts's radio and television shows, a pilgrimage point for his audience, and a university dedicated to training evangelicals in the electronic church.

    Theatre was among the first popular culture forms to address HIV/AIDS and did so memorably in such works as The Normal Heart, As Is, Love! Valor! Compassion!, and March of the Falsettos. As a response to criticisms of stage dramas focusing on HIV/AIDS in the main as undifferentiated and melodramatic, the author suggests critical consideration of two works by playwright Robert Chesley. In her analysis of Night Sweats and Jerker, the author argues Chesley offers an alternative perspective that is both liberatory and sex-positive.

    Full Text Available In this paper we analyze how Robert Nozicks minimal state proposed would invariably end, unless its members were coerced by the central government to contribute to its maintenance. And, in this case, rights and freedom protected under the philosophers state would obviously be violated. We also analyze the flaws in Nozicks model through economic bias in order to show - through game theory and logic of collective action  how an organization that provides nonexclusive public goods is vulnerable to the action of free-riders, thus increasing the costs of its performance, and decreasing motivation for its existence.

    The diaries and other writings of Robert Hooke (1635-1703), as well as those of his contemporaries, are drawn upon to sketch his social and scientific life. An account is presented of his involvement with the Royal Society from its earliest days, and of his relations with notable scientists. In exploring the similarity between combustion and respiration, he established that air is composed of different gases, and that it is not motion of the lungs but a supply of fresh air that is necessary for life.

Result indicated that survival proportion transformed seed survival curve to line were much easier than the probability adopted by Ellis and Roberts, and the most important factor affecting logp50 and δ of seed lot was interaction between t and m. Thus, Ellis and Roberts viability model were suggested to be improved as Ki=Vi-p/10K-CWT (t×m to predict longevity of seed lot with initial germination percent unknown, a new model of Gi/G0=A-P/10K-CWT(t×m was constructed to predict longevity of seed lot with initial germination percent already known.

    Full Text Available The accuracy of first pendulum gravity measurements in the Czech territory was determined using both original surveying notebooks of Robert Daublebsky von Sterneck and modern technologies. Since more accurate methods are used for gravity measurements nowadays, our work is mostly important from the historical point of view. In previous  works, the accuracy of Sterneck’s gravity measurements was determined using only a small dataset. Here we process all Sterneck’s measurements from the Czech territory (a dataset ten times larger than in the previous works, and we complexly assess the accuracy of these measurements. Locations of the measurements were found with the help of original notebooks. Gravity in the site was interpolated using actual gravity models. Finally, the accuracy of Sterneck’s measurements was evaluated as the difference between the measured and interpolated gravity.

    2013-07-01

    Robert Heath Lock (1879-1915), a Cambridge botanist associated with William Bateson and R. C. Punnett, published his book Recent Progress in the Study of Variation, Heredity, and Evolution in 1906. This was a remarkable textbook of genetics for one appearing so early in the Mendelian era. It covered not only Mendelism but evolution, natural selection, biometry, mutation, and cytology. It ran to five editions but was, despite its success, largely forgotten following Lock's early death in 1915. Nevertheless it was the book that inspired H. J. Muller to do genetics and was remembered by A. H. Sturtevant as the source of the earliest suggestion that linkage might be related to the exchange of parts between homologous chromosomes. Here we also put forward evidence that it had a major influence on the statistician and geneticist R. A. Fisher at the time he was a mathematics student at Cambridge.

    Full Text Available In diesem Aufsatz werden die Gesammelten Schriften über Musik und Musiker von Robert Schumann untersucht, insbesondere die Rezensionen, die der Komponist zwischen 1834 und 1836 verfasst hat. Es soll festgestellt werden, inwiefern sich darin die wichtigsten Auffassungen über Sprache und Übersetzung, die Ende des 18. und Beginn des 19. Jahrhunderts in Deutschland entstanden, wiederfinden. Im Vordergrund der Untersuchung steht die Dimension der Bewegung, die sich sowohl im Individuum als auch in der Zeit festmachen lässt. Im Individuum manifestiert sich die Bewegung als ein sehr persönlicher Vorgang, da es sich innerhalb verschiedener Zeichensysteme bewegt, die seine Gedanken ausdrücken; oder aber es bewegt sich innerhalb verschiedener Sprachen. Die Zeitdimension wiederum bedeutet, in ein Umfeld einzutauchen, das die Zeitbarrieren überwindet und die Vergangenheit auf einen Schlag mit der Gegenwart und der Zukunft verbindet.

  12. [Margaret Cavendish vs Robert Hooke: An impossible duel].

    Science.gov (United States)

    Aït-Touati, Frédérique

    2016-12-01

    In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article.

  13. The diffident naturalist Robert Boyle and the philosophy of experiment

    CERN Document Server

    Sargent, Rose-Mary

    2009-01-01

    In a provocative reassessment of one of the quintessential figures of early modern science, Rose-Mary Sargent explores Robert Boyle's philosophy of experiment, a central aspect of his life and work that became a model for mid- to late seventeenth-century natural philosophers and for many who followed them. Sargent examines the philosophical, legal, experimental, and religious traditions-among them English common law, alchemy, medicine, and Christianity-that played a part in shaping Boyle's experimental thought and practice. The roots of his philosophy in his early life and education, in his religious ideals, and in the work of his predecessors-particularly Bacon, Descartes, and Galileo-are fully explored, as are the possible influences of his social and intellectual circle. Drawing on the full range of Boyle's published works, as well as on his unpublished notebooks and manuscripts, Sargent shows how these diverse influences were transformed and incorporated into Boyle's views on and practice of experiment.

    Full Text Available The films of French director Robert Bresson are considered sober and transcendental. However, in A gentle woman (1969 and in Four nights of a dreamer (1972, he included extracts of quite different genres, like a libertine comedy (the extract of film Benjamim by Michel Deville, 1968, a Shakespearean tragedy (a performance of Shakespeare´s Hamlet and a gangster film (When love possesses us, produced by Bresson himself. In a way, those excerpts represent exactly the opposite of Bresson´s cinema. On the other hand, they still have some familiarity with it. We analyze the approach of those genres in the sequences in Bresson´s films, as well of the styles present in them by the use of music and images of paintings.

  15. Hooke's figurations: a figural drawing attributed to Robert Hooke.

    2010-09-20

    The experimental philosopher Robert Hooke (1635-1703) is known to have apprenticed to the leading painter Peter Lely on his first arrival in London in the late 1640s. Yet the relevance of Hooke's artistic training to his mature draughtsmanship and identity has remained unclear. Shedding light on that larger interpretive problem, this article argues for the attribution to Hooke of a figural drawing now in Tate Britain (T10678). This attributed drawing is especially interesting because it depicts human subjects and bears Hooke's name functioning as an artistic signature, both highly unusual features for his draughtsmanship. From evidence of how this drawing was collected and physically placed alongside images by leading artists in the early eighteenth century, I suggest how it can offer new insight into the reception of Hooke and his graphic work in the early Enlightenment.

    2005-12-01

    Between 1875 and 1910 Sir Robert Stawell Ball gave an estimated 2,500 lectures in towns and cities all over the British Isles and abroad. This paper traces his lecturing career from its beginnings in Ireland to the triumphs of the Royal Institution, and on lecture tours in the United States of America. After a period in mathematics and mechanics, he became a populariser of science, especially astronomy, and found fame and fortune among the working classes and the aristocracy. What motivated him to tireless travels is uncertain, but it might have been that it was rewarding, financially and to his reputation. Whatever his motives, contemporary accounts are clear that BallÕs lectures were extremely popular and well-received.

    2006-12-01

    Full Text Available This article is a study of Robert Musil´s work “The Man Without Qualities” from philosophical sources. It is a novel that has produced so many overriding metaphors through which we can better understand the crises of the social identity on the horizont of the last modernity in Europe. Much of the key-concepts that helped in creating the so called “Leyend of Modernity” start to vanish in an irremediable way: not only did Musil trace the disappearance of the support for national aspirations and social cohesion, he also showed us how culture is a mad carrousel of collapsed expectations, and how the prevailing idea of “subjectivity” lacks today any solid or essential nucleus. In the middle of this disenchanted landscape of Europe, where all the modern and clasical illusions became nothing, appears however “a new human being”, since the man “without qualities” is the man with endless possibilities too.El presente ensayo es una interpretación de la novela de Robert Musil “El hombre sin atributos” a partir de fuentes filosóficas. Se trata de una obra que ha producido algunas metáforas decisivas para comprender las crisis de la identidad social en el horizonte de la última modernidad europea. Muchos de los conceptos clave que ayudaron a crear la leyenda de la modernidad empiezan a erosionarse de modo irreversible: se descomponen las aspiraciones nacionales, el sujeto pierde su núcleo sustancial y la cultura es un carrusel de esperanzas abortadas incapaces de responder a ninguna idea rectora. Y, sin embargo, en el paisaje de esta Europa tardomoderna en que se han agotado las pasadas ilusiones surge la idea de que el “hombre sin atributos” es también el “hombre de las posibilidades”.

    West, John B

    2014-07-01

    Robert Hooke (1635-1703) was a polymath who made important contributions to respiratory physiology and many other scientific areas. With Robert Boyle, he constructed the first air pump that allowed measurements on small animals at a reduced atmospheric pressure, and this started the discipline of high-altitude physiology. He also built the first human low-pressure chamber and described his experiences when the pressure was reduced to the equivalent of an altitude of ∼2,400 m. Using artificial ventilation in an animal preparation, he demonstrated that movement of the lung was not essential for life. His book Micrographia describing early studies with a microscope remains a classic. He produced an exquisite drawing of the head of a fly, showing the elaborate compound eye. There is also a detailed drawing of a flea, and Hooke noted how the long, many-jointed legs enable the insect to jump so high. For 40 years, he was the curator of experiments for the newly founded Royal Society in London and contributed greatly to its intellectual ferment. His mechanical inventions covered an enormous range, including the watch spring, the wheel barometer, and the universal joint. Following the Great Fire of London in 1666, he designed many of the new buildings in conjunction with Christopher Wren. Unfortunately, Hooke had an abrasive personality, which was partly responsible for a lack of recognition of his work for many years. However, during the last 25 years, there has been renewed interest, and he is now recognized as a brilliant scientist and innovator. ©2014 Int. Union Physiol. Sci./Am. Physiol. Soc.

    The transfer of energy and momentum between the terrestrial magnetosphere and ionosphere is substantially mediated by large-scale field-aligned currents (FACs), driven by magnetopause dynamics and magnetospheric pressures and closing through the ionosphere where the dissipation and drag are governed. While significant insight into ionospheric electrodynamics and the nature of magnetosphere-ionosphere (M-I) coupling have been gained by rocket and satellite measurements, in situ measurement of these ionospheric closure currents remains challenging. To date the best estimates of ionospheric current densities are inferred from ground-based radar observations combining electric fields calculated from drifts with conductivities derived from densities. RICCI aims to observe the structure of the ionospheric currents in situ to determine how the altitude structure of these currents is related to precipitation and density cavities, electromagnetic dynamics, and governs energy dissipation in the ionosphere. In situ measurement of the current density using multi-point measurements of the magnetic field requires precise attitude knowledge for which the only demonstrated technique is the use of star camera systems. The low vehicle rotation rates required for miniature commercial off-the-shelf (COTS) star cameras prohibit the use of available rocket sub-payload technologies at Wallops Flight Facility (WFF) which use high rates of spin to stabilize attitude. However, CubeSat attitude systems are already designed to achieve low vehicle rotation rates, so RICCI will use a set of three CubeSat sub-payloads deployed from a main low altitude payload with apogee of 160 km to provide precise current density measurement through the ionospheric closure altitude regime, together with a second rocket with apogee near 320 km to measure the incident input energy flux and convection electric field. The two rocket payloads and CubeSate sub-payloads are all instrumented with star cameras and

    2012-02-01

    We show that it is possible to realize a " μ-split SUSY" scenario (Cheng and Cheng, 2005) [1] in the context of large volume limit of type IIB compactifications on Swiss-cheese Calabi-Yau orientifolds in the presence of a mobile space-time filling D3-brane and a (stack of) D7-brane(s) wrapping the "big" divisor. For this, we investigate the possibility of getting one Higgs to be light while other to be heavy in addition to a heavy higgsino mass parameter. Further, we examine the existence of long lived gluino that manifests one of the major consequences of μ-split SUSY scenario, by computing its decay width as well as lifetime corresponding to the three-body decays of the gluino into either a quark, a squark and a neutralino or a quark, squark and goldstino, as well as two-body decays of the gluino into either a neutralino and a gluon or a goldstino and a gluon. Guided by the geometric Kähler potential for Σ obtained in Misra and Shukla (2010) [2] based on GLSM techniques, and the Donaldson's algorithm (Barun et al., 2008) [3] for obtaining numerically a Ricci-flat metric, we give details of our calculation in Misra and Shukla (2011) [4] pertaining to our proposed metric for the full Swiss-cheese Calabi-Yau (the geometric Kähler potential being needed to be included in the full moduli space Kähler potential in the presence of the mobile space-time filling D3-brane), but for simplicity of calculation, close to the big divisor, which is Ricci-flat in the large volume limit. Also, as an application of the one-loop RG flow solution for the higgsino mass parameter, we show that the contribution to the neutrino masses at the EW scale from dimension-six operators arising from the Kähler potential, is suppressed relative to the Weinberg-type dimension-five operators.

    In Tahiti he had ambitious writing plans but after four years of living in Tahiti, he left his plantation and sailed to the Cook Islands. He spent the rest of his life in the Cook Islands and married a local girl Ngatokorua. His new happiness gave him the inspiration to write. 29 sketches appeared in the United States in 1929, collected by The Century Company under the title of The Book of Puka-Puka. His second book My Tahiti, a book of memories, was published in 1937. After the death of Ropati 's beloved wife his goals were to bring up his children. But by this time Frisbie was seriously ill. The family left Puka-Puka and settled down on the uninhabited atoll of Suwarrow. Later on they lived on Rarotonga and Samoa where Frisbie was medically treated. Robert Dean Frisbie died of tetanus in Rarotonga on November 18, 1948. Frisbie wrote in a vivid, graceful style. His characters and particularly the atoll of Puka-Puka are memorably depicted. Gifted with a feeling for language and a sense of humor, he was able to capture on paper the charm, beauty, and serenity of life of the small islands in the South Pacific without exaggerating the stereotypical idyllic context and as such Frisbie's contribution to South Pacific literature went far deeper than that of many writers who have passed through the Pacific and wrote about their experiences. Frisbie's first book The Book of Puka-Puka was published in New York in 1929. It is the most endearing and the most original of his works. It was written during his lifetime on the atoll Puka-Puka in the Cook Islands. It is a collection of 29 short stories, episodic and expressively narrative in style. This is an account of life on Puka-Puka that criticizes European and American commercialism and aggressiveness, and presents the themes of the praise of isolation, the castigation of missionaries, and the commendation of Polynesian economic collectivism and sexual freedom. At the same time, the book presents a portrait of Frisbie himself

    Former CERN Director Robert Lévy-Mandel passed away on 3 July at the age of 87.   After obtaining a diploma from the Institut polytechnique in Grenoble, in 1948 he started work at the CEA, and was involved in the development and construction of the Saclay institute's first particle accelerator, a Van de Graaff machine. From 1954 to 1957 he was responsible for the coordination, development and construction of the CEA’s Saturne synchrotron, which entered service in 1958. In 1963 he was appointed head of the Saturne Synchrotron Department. The team led the construction of the Gargamelle bubble chamber, which was installed at CERN, and made contributions to other major facilities, including the Big European Bubble Chamber (BEBC). In 1971 he was invited to come to Geneva by John Adams, who was in charge of the SPS accelerator project. With the start of the SPS project, CERN had two laboratories, one at Meyrin and one at Prévessin, each with its own Director General: ...

    Tony came from Netherton, a small town near Birmingham in the English West Midlands, where he grew up with his parents, who ran the local grocery store, "T.W. Roberts & Son". This is where he regularly liked to return, firstly to help his parents and later simply to spend time with them. Here undoubtedly lie the roots of his organizational skills and his ability to get on so well with others. He soon became interested in the rapidly-developing field of computing and this was how he first came to CERN, during the summer of 1973, at the age of 25. He joined the DD Division as an operator responsible for the "calculators" of that time, where he stayed until 1979 when he joined the Fellows and Associates Section of Personnel Division. He participated in the general computerisation of the Administration and continued his career in the Records Office of HR Department, a post he held until the end. Though still very British – ob...

    Full Text Available In 2013 the Nobel Prize in Economic Sciences was awarded to the American economists, Eugene Fama, Lars Peter Hansen and Robert Shiller. The monetarists, Fama and Hansen, from the University of Chicago, and the Neo- Keynesian, Shiller, from the Yale University, according to the Swedish Royal Academy, won this prestigious prize for their research providing mathematical and economic models to determine (irregularities in the stock value trends at the stock exchanges. With his colleagues, in the 1960s Fama established that, in the short term, it is extremely difficult to forecast stock prices, given that new information gets embedded in the prices rather quickly. Shiller, however, determined that, although it is almost impossible to predict the stock prices for a period of few days, this is not true for a period of several years. He discovered that the stock prices fluctuate much more substantially than corporation dividents, and that the relationship between prices and dividends tends to decline when high, and to grow when low. This pattern does not apply only to stocks, but also to bonds and other forms of capital.

  10. Robert Wood Johnson Foundation Nurse Faculty Scholars program leadership training.

    Campbell, Jacquelyn C; McBride, Angela Barron; Etcher, LuAnn; Deming, Katie

    The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing shortage via development of the next generation of national leaders in academic nursing. The leadership training combined development at the scholar's home institution with in-person didactic and interactive sessions with notable leaders in nursing and other disciplines. A curriculum matrix, organized by six domains, was evaluated quantitatively and qualitatively. What set this program apart is that it immersed junior faculty in concerted leadership development with regard to all aspects of the faculty role so that teaching interactively, making use of the latest in information technology, giving testimony before a policy-making group, participating in strategic planning, and figuring out how to reduce the budget without jeopardizing quality were all envisioned as part of the faculty role. The domains covered by this program could easily be used as the framework to plan other leadership-development programs for the next generation of academic leaders. Copyright © 2017 Elsevier Inc.

  12. Statistical ultrasonics: the influence of Robert F. Wagner

    Insana, Michael F.

    2009-02-01

    An important ongoing question for higher education is how to successfully mentor the next generation of scientists and engineers. It has been my privilege to have been mentored by one of the best, Dr Robert F. Wagner and his colleagues at the CDRH/FDA during the mid 1980s. Bob introduced many of us in medical ultrasonics to statistical imaging techniques. These ideas continue to broadly influence studies on adaptive aperture management (beamforming, speckle suppression, compounding), tissue characterization (texture features, Rayleigh/Rician statistics, scatterer size and number density estimators), and fundamental questions about how limitations of the human eye-brain system for extracting information from textured images can motivate image processing. He adapted the classical techniques of signal detection theory to coherent imaging systems that, for the first time in ultrasonics, related common engineering metrics for image quality to task-based clinical performance. This talk summarizes my wonderfully-exciting three years with Bob as I watched him explore topics in statistical image analysis that formed a rational basis for many of the signal processing techniques used in commercial systems today. It is a story of an exciting time in medical ultrasonics, and of how a sparkling personality guided and motivated the development of junior scientists who flocked around him in admiration and amazement.

    Full Text Available This paper analyzes Robert Lucas's contribution to economic theory between 1967 (year of his first solo publication and 1981 (the year before the emergence of Real Business Cycle approach, and it has two parts. The first one, using citation data from three different sources, we try to answer two questions: (i What are Lucas's most influential papers currently? (ii How has this influence changed through time? We show, for instance, that according to two of those three sources, Lucas's most influential paper today is not from his business cycle research agenda, which gave him his Nobel Prize in 1995. Moreover, it is clear the loss of influence of Lucas's macroeconomic theory since the early 1980s. In the second part, by cataloging all the works that Lucas had used as bibliographical references in his papers and separating them in two categories (positive and negative, we try to understand who exerted influence on him. We show that the author that Lucas most cited in a positive context were John Muth, Milton Friedman and Edmund Phelps. The authors more often cited in a negative context were John M. Keynes and A. W. Phillips. We discuss the reasons behind this data.

  14. Robert Boyle and the representation of imperceptible entities.

    Science.gov (United States)

    Wragge-Morley, Alexander

    2018-03-01

    In this essay, I examine Robert Boyle's strategies for making imperceptible entities accessible to the senses. It is well known that, in his natural philosophy, Boyle confronted the challenge of making imperceptible particles of matter into objects of sensory experience. It has never been noted, however, that Boyle confronted a strikingly similar challenge in his natural theology - he needed to make an equally imperceptible God accessible to the senses. Taking this symmetrical difficulty as my starting point, I propose a new approach to thinking about the interconnections between Boyle's natural philosophy and natural theology. For the most part, studies of science and religion in the early modern period work by seeking out the influence of explicitly stated religious beliefs on scientific ideas. I argue, by contrast, that we need to focus on Boyle's representational practices, using his attempts to represent imperceptible entities as a means of uncovering metaphysical and theological presuppositions that he did not always articulate when stating his religious beliefs. With new interpretations of both A Discourse of Things Above Reason (1681) and Some Physico-Theological Considerations about the Possibility of the Resurrection (1675), I show that there were crucial similarities between Boyle's practices for representing both God and atoms. I go on to show, moreover, that Boyle used these practices to enact an ontological stance at odds with one of his most important professed beliefs.

    Full Text Available http://dx.doi.org/10.5007/2175-8026.2017v70n2p107 Ae, the narrator-protagonist of the novel Stone, by Adam Roberts, is the only criminal in a post-human utopian society in which the use of nanotechnology has allowed humanity to reach its plenitude. Isolated from the rest of society, one day Ae is offered freedom and wealth if he agrees to kill the population of a whole planet. After accepting this offer, Ae must try to fulfil his mission at the same time that he questions himself and tries to discover who his employers are. In developing the conflict between this deviant individual and the utopia in which he lives, Stone examines the limits of the utopia itself, which is based on the idea of flux and indefiniteness. The novel also explores the models of subjectivity created in the context of this utopia. The notion of utopia as a well-defined social project is replaced by the image of utopian bodies, influenced by technologies that challenge the definitions of the human and of the post-human. In establishing this network of tensions and indefiniteness, the novel offers the possibility that the marginalized sociopath might be the only one capable of examining in depth the reality of a world anesthetized by its own comfort.

    To evaluate the effectiveness of the Robert view in assessing trapeziometacarpal arthrosis and to compare the accuracy of the Robert and lateral views in staging trapeziometacarpal (TM) joint arthrosis. Patient demographics were obtained. Four participating raters reviewed 62 randomly selected thumb x-rays of patients presenting with thumb TM joint pain. Lateral and Robert-hyperpronation views were assessed using an analysis of 13 criteria. X-rays of 62 thumbs for 58 patients were evaluated. The average patients' age was 64 (47-87) and 51 (80%) were females. The majority of X-rays evaluated fell into stage 3. Stage 2 was the second most common level of arthritis encountered and the least was stage 1. More osteophytes were encountered in the trapezium than metacarpal on both the Robert and lateral views. The Robert view was superior in detecting osteophytes on the trapezium than the lateral view. Osteophyte size varied from 1.7 to 2 mm. The lateral view displayed 61 cases with dorsal metacarpal subluxation (98%). The Robert view displayed 48 cases (77%) with radial metacarpal subluxation and 9 cases (15%) with ulnar metacarpal subluxation. Thumb metacarpal adduction deformity was encountered on the lateral view in 20 cases (32%) whereas on the Robert view it was encountered in 14 cases (23%). Subchondral sclerosis was encountered on the Robert view in 56 thumbs (90%) while it was seen on the lateral view in 52 thumbs (84%). Pantrapezial arthritis involving the STT joint was encountered equally in 16 cases (26%) on the Robert view and the lateral views. The study found a moderate level of interrater reliability on both the lateral and Robert views. With the exception of osteophytes encountered on the trapezium versus the metacarpal, there were no other statistically significant findings. This study confirms that each of the Robert and lateral views offer unique information and combining both views enhances the ability to assess radiographic disease severity, and

    The paper summarises the accessible literature on the life and work of well-known American lung surgeon, Professor Dr. Med. Robert Klopstock, who was in the years 1920-1924 a friend Franz Kafka. Professor Klopstock was of Hungarian origin and he got acquainted with Franz Kafka at the end of the year 1920 in Tatranské Matliare (The High Tatras). They were both patients treated for lung tuberculosis. They became close friends and their mutual correspondence shows their real friendship. Robert Klopstock was present at Franz Kafka's death-bed on June 3, 1924 in Kierling, near Klosterneuburg, not far from Vienna. Robert Klopstock studied at Medical Faculties of the Universities in Budapest, Prague, Kiel and Berlin. After his graduation in 1933 in Berlin, he worked as a lung surgeon at various surgical clinics and departments in Budapest and Berlin. In 1936 Robert Klopstock together with his wife visited the High Tatras and Tatranské Matliare. In 1937 Robert Klopstock with his wife Gizela, a writer and a translator, who translated the first chapters of Franz Kafka's novel "Trial" into Hungarian language, went to United States of America. During his stay in U.S.A. Dr. Med. Robert Klopstock was very active as a lung surgeon and a scientist. He published 64 specialized scientific papers, mostly in American medical journals. He became Professor of Lung Surgery at Downstate Medical Centre in New York-Brooklyn. He died on June 15, 1972 in New York.

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

Manuscripts for the Letters should, as before, be sent directly to Dr. Alex Dalgarno at the Center for Astrophysics in Cambridge, MA. We are fortunate that a person with as much experience in research and proven good judgment as Dr. Kennicutt is willing to accept this difficult and time-consuming responsibility. He will be only the seventh Managing Editor or Editor-in-Chief that this Journal has had in its 104 years. Please give him the cooperation and help that you have given the current editor. It has been my privilege to work for 28 years with many of the best astrophysicists in the world and to publish their papers. This was done with the help of the AAS Publications Board and AAS officers, the efforts of Peter Boyce and Evan Owens who made the on-line edition of the Journal possible, three Associate Editors, a score of Scientific Editors, a hardworking staff of six in Tucson, up to 25 production controllers and manuscript editors at the University of Chicago Press, and the thousands of astronomers throughout the world who served as referees.

    The publishers of Physics in Medicine and Biology (PMB), IOP Publishing, in association with the journal owners, the Institute of Physics and Engineering in Medicine (IPEM), jointly award the Roberts prize for the best paper published in PMB during the previous year. The procedure for deciding the winner is a two-stage process. First, a shortlist of contenders is drawn up based on those papers that had the best referees' quality assessments, with a further quality check and endorsement by the Editorial Board. The papers on the shortlist are then reviewed by a specially convened IPEM committee consisting of members with fellow status. This committee reads the shortlisted papers and selects the winner. We have much pleasure in advising readers that the Roberts Prize for the best paper published in 2012 is awarded to Michel Defrise, Ahmadreza Rezaei and Johan Nuyts from the Vrije Universiteit Brussels and the Katholieke Universiteit Leuven, Belgium for their breakthrough paper that describes how the information needed for attenuation correction in PET imaging can be extracted, to within a constant, from time-of-flight emission data: Time-of-flight PET data determine the attenuation sinogram up to a constant 2012 Phys.

In hybrid PET/CT scanners, the PET attenuation correction, necessary for quantitative reconstruction of the tracer distribution, can be derived directly from the CT data. Sometimes, however, the PET and CT scans may be poorly aligned due to patient motion and other approaches are needed. In addition, hybrid PET/MRI scanners also, have been developed recently, and in

    2016-01-01

    Full Text Available There are several syndromes in which specific mitotic chromosomal abnormalities can be seen, like premature centromere separation, premature (sister chromatid separation, and somatic aneuploidies. Identifications of such specific cytogenetic findings can be the key factor that leads towards the diagnosis of syndromes like Roberts SC phocomelia. The case presented here as Roberts SC phocomelia syndrome was identified as a child with multiple congenital anomalies and dysmorphic features. Conventional cytogenetic analysis of the case revealed premature sister chromatid separation. The premature centromeric separation was also confirmed by C banding analysis of the child. It is the first and the only case of Roberts SC phocomelia diagnosed from this part of the world. The present case report emphasizes the importance of conventional cytogenetics in the diagnosis of such syndromes.

  18. Numerical Methods in Atmospheric and Oceanic Modelling: The Andre J. Robert Memorial Volume

    Science.gov (United States)

    Rosmond, Tom

    Most people, even including some in the scientific community, do not realize how much the weather forecasts they use to guide the activities of their daily lives depend on very complex mathematics and numerical methods that are the basis of modern numerical weather prediction (NWP). André Robert (1929-1993), to whom Numerical Methods in Atmospheric and Oceanic Modelling is dedicated, had a career that contributed greatly to the growth of NWP and the role that the atmospheric computer models of NWP play in our society. There are probably no NWP models running anywhere in the world today that do not use numerical methods introduced by Robert, and those of us who work with and use these models everyday are indebted to him.The first two chapters of the volume are chronicles of Robert's life and career. The first is a 1987 interview by Harold Ritchie, one of Robert's many proteges and colleagues at the Canadian Atmospheric Environment Service. The interview traces Robert's life from his birth in New York to French Canadian parents, to his emigration to Quebec at an early age, his education and early employment, and his rise in stature as one of the preeminent research meteorologists of our time. An amusing anecdote he relates is his impression of weather forecasts while he was considering his first job as a meteorologist in the early 1950s. A newspaper of the time placed the weather forecast and daily horoscope side by side, and Robert regarded each to have a similar scientific basis. Thankfully he soon realized there was a difference between the two, and his subsequent career certainly confirmed the distinction.

     The Roberts Court and the “municipal prayer” Abstract: In the USA, few topics are more divisive than the government’s use of religious expressions and symbols. The Supreme Court has tried to find a balance between the Establishment Clause of the U.S. Constitution and the inclusion of religious expressions in government activities. In Town of Greece v. Galloway, the Roberts Court upheld a town’s practice of opening board meetings with prayers from invited speakers. The essay critically examines the various opinions in the case, and looks at where this decision suggests the Establishment Clause doctrine is moving award.

  15. Topological network entanglement as order parameter for the emergence of geometry

    International Nuclear Information System (INIS)

    Diamantini, M Cristina; Trugenberger, Carlo A

    2017-01-01

    We show that, in discrete models of quantum gravity, emergent geometric space can be viewed as the entanglement pattern in a mixed quantum state of the ‘universe’, characterized by a universal topological network entanglement. As a concrete example we analyze the recently proposed model in which geometry emerges due to the condensation of 4-cycles in random regular bipartite graphs, driven by the combinatorial Ollivier–Ricci curvature. Using this model we show that the emergence of geometric order decreases the entanglement entropy of random configurations. The lowest geometric entanglement entropy is realized in four dimensions.

    Full Text Available Sociology, science and political philosophy are the disciplinary fields that have guided Robert M. Maclver's investigation. This is based on accurate intuition always present in his thought: to study human social action in order to set up a realistic theory on democracy with important federal contents by reason of an understanding of the relation between society and state. At this relation, state is a simple mean belonging to the sphere of civilization and society is an original reality (a "network of groups and communities", in which the primary interests of any social being are expressed.

    Sociología, ciencia y filosofía política son los ámbitos disciplinares que han guiado y alimentado, compenetrándose, la investigación de Robert M. Maclver.

  1. The importance of chromosome studies in Roberts syndrome/SC phocomelia and other cohesinopathies.

    Roberts syndrome/SC phocomelia is a rare, autosomal recessive syndrome characterised by pre- and postnatal growth retardation, microcephaly, craniofacial anomalies, mental retardation, and tetraphocomelia in varying degrees of severity. The clinical diagnosis can be challenging in phenotypically mild cases. In the extremely mild case presented here, specific mitotic abnormalities were detected and proved to be very helpful, since Roberts syndrome/SC phocomelia could be diagnosed after finding premature centromere separation and somatic aneuploidy at routine karyotyping. We discuss these and other mitotic cytogenetic abnormalities that can be of significant diagnostic importance, but which will be missed if only array studies are performed. We also discuss the difference between premature centromere separation and premature (sister) chromatid separation. Copyright (c) 2009 Elsevier Masson SAS. All rights reserved.

  2. Robert Hooke, inventor of the vacuum pump and the first altitude chamber (1671).

    2006-08-01

    Robert Hooke (1635-1703), an assistant researcher to Robert Boyle (1627-1691), invented the first functional British air pump. Applying it to scientific research, Hooke operated the world's first hypobaric chamber in 1671, using it for self-experimentation. He recorded the first physiological observations in an artificial altitude-equivalent environment up to 2400 m. Though Hooke's experiment showed some methodological insufficiencies, his imaginative experimental techniques were remarkable for their time and were indicative of the lively intellectual atmosphere of the Royal Society and the significant contributions of Hooke, who was a member. Two centuries passed before the French physiologist Paul Bert (1830-1886) conducted his famous laboratory-supported investigations of high altitude physiology. Bert played a decisive role in the discovery of the causes of decompression sickness; a contribution Hooke could not make due to the technical deficiencies of the 17th century.

  3. [Robert Koch was right. Towards a new interpretation of tuberculin therapy].

    Cardona, Pere J

    2006-01-01

    At the centenary of Robert Koch's Nobel Prize award, tuberculosis treatment with tuberculin, which was announced in Berlin in 1890, is still considered a failure. Nevertheless, there is now sufficient information supporting the idea that tuberculin therapy was widely used until the second half of the twentieth century; thus, the impact of this treatment should be studied and related to the decrease in tuberculosis-related mortality recorded in that period. Moreover, tuberculin therapy has inspired at least two new immunotherapies; these, however, were directed toward precisely the opposite effect: suppression of the Koch phenomenon. Thus, inoculation of Mycobacterium vaccae polarizes the immune response towards the Th1 type; and inoculation of RUTI avoids local immunodepression after short-term chemotherapy without inducing toxicity. For this reason, Robert Koch's work on antituberculosis therapy should be reread and proper recognition given to his contribution in this field.

  4. Invited commentary on 'Robert G Edwards and the Roman Catholic Church'.

    In this issue of Reproductive BioMedicine Online, Benagiano, Carrara and Filippi have produced a clearly written and comprehensive account of why the Roman Catholic Church has not welcomed the award of the 2010 Nobel Prize in Physiology and Medicine to Dr Robert G Edwards for the development of human IVF. I commend the article for its clarity and lucidity but attempt to point out some areas where disagreement even with its nuanced opposition to IVF may be legitimate. I try to make some simple comments that explain why this is so and I suggest some areas to which contemporary theology and philosophy can commit itself. But it is good to see even a nuanced response to the work of Robert G Edwards rather than a blanket condemnation. Copyright © 2011 Reproductive Healthcare Ltd. Published by Elsevier Ltd.

    2013-12-01

    Charles Darwin and Alfred Russel Wallace independently discovered the mechanism of natural selection for evolutionary change. However, they viewed the working of selection differently. For Darwin, selection was always focused on the benefit for the individual. For Wallace, selection was as much something of benefit for the group as for the individual. This difference is traced to their different background political-economic views, with Darwin in favor of Adam Smith's view of society and Wallace following Robert Owen in being a socialist.

  13. Homosexual orientation-from nature, not abuse: A critique of Roberts, Glymour, and Koenen (2013).

    Science.gov (United States)

    Rind, Bruce

    2013-11-01

    Roberts, Glymour, and Koenen (2013), using instrumental variable models, argued that child abuse causes homosexual orientation, defined in part as any same-sex attractions. Their instruments were various negative family environment factors. In their analyses, they found that child sexual abuse (CSA) was more strongly related to homosexual orientation than non-sexual maltreatment was, especially among males. The present commentary therefore focused on male CSA. It is argued that Roberts et al.'s "abuse model" is incorrect and an alternative is presented. Male homosexual behavior is common in primates and has been common in many human societies, such that an evolved human male homosexual potential, with individual variation, can be assumed. Cultural variation has been strongly influenced by cultural norms. In our society, homosexual expression is rare because it is counternormative. The "counternormativity model" offered here holds that negative family environment weakens normative controls and increases counternormative thinking and behavior, which, in combination with sufficient homosexual potential and relevant, reinforcing experiences, can produce a homosexual orientation. This is a benign or positive model (innate potential plus release and reinforcement), in contrast to Roberts et al.'s negative model (abuse plus emotional compensation or cognitive distortion). The abuse model is criticized for being based on the sexual victimological paradigm, which developed to describe the female experience in rape and incest. This poorly fits the gay male experience, as demonstrated in a brief non-clinical literature review. Validly understanding male homosexuality, it is argued, requires the broad perspective, as employed here.

    Stone, J L

    2001-10-01

    JOHN BINGHAM ROBERTS (1852-1924) of Philadelphia was an active general surgeon in the latter 19th and early 20th centuries. He made pioneering contributions to a number of areas of surgery. From 1880 until the end of his career, he was one of the few American surgeons to advocate an aggressive exploratory approach to cranial fractures in an effort to avoid consequences such as infection, delayed seizures, and insanity. In his 1885 article in the Transactions of the American Surgical Association titled "The Field and Limitation of the Operative Surgery of the Human Brain," he predicted that with antiseptic precautions and the growing knowledge of cerebral localization, operations on the brain would become commonplace. This work predated that of Horsley, Keen, and many others. Roberts had a continuing interest in head injuries, cranial fractures, and the development of trephines and burrs for reconstructive cranial work, but his active enthusiasm for brain surgery diminished in the 1890s. Nevertheless, Roberts was a very prolific teacher and leader in American surgery who is perhaps best remembered for his monographs and textbooks on general, orthopedic, plastic, and reconstructive surgery.

    2003-07-01

    Full Text Available The Robert/SC (pseudothalidomide syndrome is a rare autosomal recessive disorder, associated with phocomelia and craniofacial abnormalities. An anomalous fetus with lower limb phocomelia and micromelia, lumbar myeloschisis, upper limb and ribs defects and craniofacial abnormalities is reported whose diabetic mother took mebendazole and glibenclamide in early pregnancy. Ultrasonographic findings of syndromes with phocomelia are discussed as well as Robert/SC syndrome which is the most probable diagnosis. Robert/SC phocomelia syndrome is a rare autosomal recessive condition characterized by severe pre and postnatal growth deficiency, symmetric limb reductions of variable severity and craniofacial anomalies including hypertelorism, hypoplastic nasal alae, cleft lip and palate. About half of the reported cases presented chromosomal abnormalities. We think that findings in our case are consistent with Robert/SC syndrome with additional abnormalities.

    Kiselev Aleksandr

    2014-12-01

    Full Text Available Despite the fact that Robert Harley is known as Tory politician, he began his career as a Whig politician. His grandfather and father were Presbyterians, and Robert Harley himself was a Presbyterian during his entire life. Harley’s family supported the Glorious Revolution of 1688. In 1689 Robert Harley was first elected to the House of Commons as a representative of the Whig party. Thanks to his wife’s Foley family, Robert Harley was elected as a commissioner of public accounts in the House of Commons. In 1689 Britain entered the “war of King William” which was a burden for many gentry (Whigs or Tories. Robert Harley became famous in the parliament as a critic of the war and corruption in the army. In 1693 the Whig leaders headed the ministry and continued the war. Their policy divided the Whigs party in two factions: “Court Whigs” and “Country Whigs”. Robert Harley and his supporters became “Country Whigs”, and they criticized the “Court Whigs”. By 1700 Robert Harley joined the Tory party. The article also describes the evolution of historiography of Harley‘s policy. Victorian historians have called the Prime Minister a “stupid person”. The same opinion was repeated by Russian historians of the 19th century. But in the 20th century the assessment of Robert Harley’s activity was changed by the works of K. Feiling, G. Holmes, B.W. Hill and other historians. Soviet historians (for example M.A. Barg also called R.Harley a “mediocre politician”, but modern Russian historians (L.I. Ivonina, T.L. Labutina and others consider him a “clever statesman” and a “master of political intrigues and parliamentary diplomacy”.

  17. Towards large volume big divisor D3/D7 “μ-split supersymmetry” and Ricci-flat Swiss-cheese metrics, and dimension-six neutrino mass operators

    International Nuclear Information System (INIS)

    Dhuria, Mansi; Misra, Aalok

    2012-01-01

    We show that it is possible to realize a “μ-split SUSY” scenario (Cheng and Cheng, 2005) in the context of large volume limit of type IIB compactifications on Swiss-cheese Calabi-Yau orientifolds in the presence of a mobile space-time filling D3-brane and a (stack of) D7-brane(s) wrapping the “big” divisor. For this, we investigate the possibility of getting one Higgs to be light while other to be heavy in addition to a heavy higgsino mass parameter. Further, we examine the existence of long lived gluino that manifests one of the major consequences of μ-split SUSY scenario, by computing its decay width as well as lifetime corresponding to the three-body decays of the gluino into either a quark, a squark and a neutralino or a quark, squark and goldstino, as well as two-body decays of the gluino into either a neutralino and a gluon or a goldstino and a gluon. Guided by the geometric Kähler potential for Σ B obtained in Misra and Shukla (2010) based on GLSM techniques, and the Donaldson's algorithm (Barun et al., 2008) for obtaining numerically a Ricci-flat metric, we give details of our calculation in Misra and Shukla (2011) pertaining to our proposed metric for the full Swiss-cheese Calabi-Yau (the geometric Kähler potential being needed to be included in the full moduli space Kähler potential in the presence of the mobile space-time filling D3-brane), but for simplicity of calculation, close to the big divisor, which is Ricci-flat in the large volume limit. Also, as an application of the one-loop RG flow solution for the higgsino mass parameter, we show that the contribution to the neutrino masses at the EW scale from dimension-six operators arising from the Kähler potential, is suppressed relative to the Weinberg-type dimension-five operators.

    2008-01-01

    Roberts' model of lunar soil erosion beneath a landing rocket has been updated in several ways to predict the effects of future lunar landings. The model predicts, among other things, the number of divots that would result on surrounding hardware due to the impact of high velocity particulates, the amount and depth of surface material removed, the volume of ejected soil, its velocity, and the distance the particles travel on the Moon. The results are compared against measured results from the Apollo program and predictions are made for mitigating the spray around a future lunar outpost.

    Roberts/SC phocomelia syndrome (RBS) is a rare but distinct genetic disorder with an autosomal recessive inheritance pattern. It has been associated with microcephaly, craniofacial malformation, cavernous hemangioma, encephalocele, and hydrocephalus. There are no previously reported cases of RBS with intracranial aneurysms. The authors report on a patient with a history of RBS who presented with a spontaneous posterior fossa hemorrhage. Multiple small intracranial aneurysms were noted on a preoperative CT angiogram. The patient underwent emergency craniotomy for evacuation of the hemorrhage. A postoperative angiogram confirmed the presence of multiple, distal small intracranial aneurysms.

    Attempting to play the role of King Solomon in his PPACA decision, Chief Justice John Roberts split the baby perversely by ruling it was not a tax under the Anti-Injunction Act, which would have likely deprived the Court of jurisdiction to hear this pre-enforcement challenge to the individual mandate, but it was a tax for taxing and spending purposes even though Congress said it was a "penalty" and not a tax. And the Chief Justice had to twist further his "wisdom" to hold that it was not an unconstitutional direct tax, even though that is exactly what it is, if it is a tax in the first instance.

    Robert Hooke played important roles in the early development of the Royal Society of London. As Curator of Experiments of the Society, he became a pioneering microscopist, prolific inventor, astronomer, geologist, architect, and an effective surveyor of the City of London following the Great Fire of 1666. Hooke's Micrographia (1665) revealed the microscopic structures of numerous biological and inorganic objects and became an important source of information for later studies. Aside from the body of detailed observations reported and depicted in Micrographia, the Preface is in itself an extraordinary document that exhibits Hooke's fertile mind, philosophical insights, and rare ability to look into the future.

    2014-01-01

    In an influential article of 1952, Thomas Kuhn argued that Robert Boyle had little or no influence on the subsequent development of chemistry. This essay challenges Kuhn's view on two fronts. First, it shows that Johann Joachim Becher developed his hierarchical matter theory under the influence of Boyle and then transmitted it to the founder of the phlogiston theory, G. E. Stahl. Second, this essay argues that transmutational matter theories were not necessarily opposed to the existence of stable chemical species, pace Kuhn. Boyle's corpuscular theory descended largely from the tradition of "chymical atomism," which often advocated both chrysopoeia and the reality of robust chemical substances.

    Robert B. Mandell is the quintessential modern clinical scientist. Over his long academic career, he has pioneered many advances in contact lens practice, ranging from a more complete understanding of corneal shape to the effects of contact lenses on corneal health. His classic text, Contact Lens Practice, first published in 1965, was reprinted 14 times in four editions up to 1988. Mandell's contributions to the advancement of the profession of optometry have always been characterized by a genuine concern for the patient and a steadfast belief that his research must have relevance to the practice of optometry.

    2017-08-01

    Friedrich Robert Helmert died in Potsdam in 1917 at the age of 74 after serving for over 30 years as director of the Royal Prussian Geodetic Institute and of the Central Bureau of the Internationale Erdmessung, the forerunner of today's International Association of Geodesy. He dedicated his life and his scientific career to the field of geodesy. His teachings on theoretical and physical geodesy were incorporated into university curricula around the world and hence into international endeavours to measure planet Earth. The purpose of this article is to illustrate the impact he has had on the development of modern geodesy and on the related sciences.

    2005-01-01

    As editors of the Robert Wood Johnson Foundation's (RWJF's) anthology series, we have examined the entire range of the foundation's grant making since 1972. We found that the RWJF has enjoyed considerable success in building fields--from nurse practitioners to tobacco control to end-of-life care. The RWJF has done this by shaping fields as they were emerging, by adopting a wide-ranging "bear hug" approach, and by staying the course. The lessons from the RWJF's field-building efforts are relevant for both large and small foundations: Small funders can develop strategic plans aimed at building fields in their home state or locality.

    2010-12-01

    Full Text Available To a considerable extent, Romantic Orientalist literature is founded on scholasticism, authentication, quotation of antiquarian sources, in other words, on paratext. It constitutes in many respects an oxymoronic, though fascinating and dynamic, symbiosis of repetition / replication and creative imagination / invention. By focusing on Robert Southey’s art of quotation in his extraordinarily abundant notes to his orientalist narrative verse this essay seeks to establish paratext as an integral, formative aspect of Romantic Orientalism and Romantic-period poetics, illustrating the hybridity of the Romantic genius and Romantic poetic creation, and challenging common assumptions about a sublime, universal Romantic-period poetry.

    2017-10-01

    After the First World War, the young Soviet Union (USSR) desperately needed new engineers and scientists who would provide the new country with development of modern industry and transportation. At that time, Western European countries had knowledge and experience, especially in the field of aviation. One of the young engineers was Robert Bartini, who was educated in Austria-Hungary and Italy, and graduated from Milan Polytechnic Institute. In 1923, he fled Italy to escape Fascists and emigrated in Soviet Union. This article is a brief description of aircraft designer Robert Bartini and his role in the development of the military, passenger and transport aviation. In addition, it presents his vision of the intercontinental and continental high-speed transport, which was his focus in the last years of his work and creation. He worked as a researcher and expert in the former Soviet Union, therefore, more detailed and relevant information on his work has been revealed to the public in recent years. In Russia, he is very popular as a researcher and developer. There are many books about him in Russian and Italian language, but not in English. Thus, his work is still quite unknown in the West. He was born in Kanjiza (today Serbia) in 1897, and spent his youth in Fiume (Rijeka, today Croatia).

  3. James George Frazer’s Anthropologic Heritage in the Work of Robert Graves

    Directory of Open Access Journals (Sweden)

    Tomislav M. Pavlović

    2016-02-01

    Full Text Available The works of Sir James George Frazer had an outstanding influence on the literature of modernism. Among those who benefited from Frazer’s ritualism were W. B. Yeats, T. S. Eliot. James Joyce, Ernest Hemingway, D. H. Lawrence, Ezra Pound, Mary Renault, Joseph Campbell, Robert Graves and many others. Robert Graves was known for his famous adaptation of Frazer’s concept of the sacred king who is sacrificed for the benefit of his subjects thus forming the narrative frame for the one of his most controversial novels. The dying king is also identified with the poet striving to attain the favour of the Triple Muse Goddess - who represents the embodiment of true poetic inspiration. The aforementioned concept is not the only thing that Graves inherited from his famous ancestor. In our analysis we laid stress on the customs, rituals, magic symbols and deities both authors dealt with. We also observed a striking resemblance of the style Greves and Frazer developed and their euchemeristic approach to myths as well.

    This article investigates the influence of perception that is altered by psychedelic drugs on processes of creativity through a case study of the work of well-known comic artist Robert Crumb. Samples of Crumb's work before, during, and after the period of his use of psychedelic drugs are content analyzed and compared according to the categorization offered by Janiger and Dobkin de Rios (1989). The results of the comparison indicate that Robert Crumb's drug use significantly altered the stylistic approach of his artwork not only during the period of his drug use, but long after he had stopped using drugs.

    Full Text Available The article emphasizes the centrality of the concept of work in the thought of the French sociologist Robert Castel. Despite being best known in Brazil for his concepts of social question and social disaffiliation, the concept of work is crucial in the articulation of the author's thought, notably in his latest writing. The article is divided into four parts. First, it provides a general introduction to the work of Castel. Then, it demonstrates how work can be considered the main social question of contemporary global capitalism. Following, it resumes the relationship between work and social vulnerability. The study concludes by pointing out the importance of understanding work as the main contemporary social issue.

  11. The Aspiring Adept: Robert Boyle and His Alchemical Quest (Lawrence M. Principe)

    Science.gov (United States)

    Kovac, Jeffrey

    1999-10-01

    Robert Boyle is widely regarded as the Father of Modern Chemistry, who broke once and for all from the irrational, misguided alchemy that preceded him. One of the goals of this carefully researched and argued new book by Lawrence M. Principe, Assistant Professor in the Department of Chemistry and the Institute for the History of Science, Medicine, and Technology at The Johns Hopkins University, is to refute the two errors in this characterization of Boyle and to understand his life, thought, and work in the intellectual and social context of his time. This book is not for the casual reader; it is a detailed scholarly treatise in the history of science, but it provides a fresh and interesting perspective on Boyle and on the development of chemistry in the 17th century. Boyle is usually characterized as a modern scientist and his most famous book, The Skeptical Chymist, as a critique of traditional alchemy. Principe demonstrates that this characterization is based on a selective and sometimes incorrect reading of Boyle's works. Like Newton, Boyle was deeply involved in traditional transmutational alchemy, reading the works of other alchemists, performing experiments, and even witnessing transmutations. Alchemy, however, was not a monolith and Boyle adhered to what Principe tentatively identifies as a uniquely English school of supernatural alchemy. According to Principe, The Skeptical Chymist was mainly a criticism of the Paracelsians interested in chemical medicine rather than a defense of what we would now regard as modern chemistry. To further support his characterization of Boyle and to better reveal Boyle's involvement in alchemyparticularly the transmutation of base metals to gold, termed chrysopoeiaPrincipe has reconstructed from some 20 fragments one of Boyle's alchemical manuscripts, his Dialogue on the Transmutation of Metals. The full text of this lost work is included as Appendix 1. Two other primary sources, Interview Accounts of Transmutations and

  13. ANTHROPOLOGY AT WAR: ROBERT H. LOWIE AND THE TRANSFORMATION OF THE CULTURE CONCEPT, 1904 to 1954.

    Science.gov (United States)

    Bargheer, Stefan

    2017-03-01

    The concept of culture used in American anthropology has fundamentally transformed throughout the first half of the twentieth century. The changing resonance of the work of Robert H. Lowie offers revealing insights into this development. Lowie was part of the first generation of students of Franz Boas that highlighted the importance of individual variation for the study of both primitive and civilized societies. Yet, its initial resonance notwithstanding, the culture concept that prevailed in the discipline went into a different direction as the result of anthropologists' involvement in the war effort. It was advanced by the second generation of Boas' students such as Ruth Benedict and Margaret Mead, who stressed the homogeneity of cultures. The contrast highlights the diversity of approaches available within anthropology in the first half of the century and the crucial impact of World War II in determining which of these possibilities became institutionalized in the decades after the war. © 2017 Wiley Periodicals, Inc.

  14. Contemporary Hegelian Scholarship: Robert Stern’s Holistic Reading of Hegel

    Directory of Open Access Journals (Sweden)

    Paniel Reyes Cardenas

    2015-12-01

    Full Text Available This is a monographic presentation in which the author depicts the guidelines of Professor Robert Stern’s interpretation of Hegelian Metaphysics by emphasizing in its characteristic holistic reading. The proposal is that some key fundamental topics of Hegelian scholarship will emerge with a clarified understanding after this reading: the concept of Truth and absolute knowledge are reassessed by showing the necessary connection of Epistemology and Metaphysics in Hegel. Hegelian Metaphysics, accordingly, appears ultimately as the principle for a reading of Hegel’s entire philosophy and illuminates its nature of general metaphysical inquiry. Finally, this reading allows drawing on the connection of Hegel’s Idealism with the Pragmatist tradition initiated by Peirce.

    Gest, Howard

    2009-01-01

    Microorganisms were first observed by Robert Hooke and Antoni van Leeuwenhoek between 1665 and 1678. In 1665, Hooke published Micrographia, which depicted the details of 60 objects as seen in the microscope. One chapter was devoted to the microfungus Mucor, the first microbe observed by the human eye. Leeuwenhoek, despite having no scientific training, became the first to observe protozoa, red blood cells, the sperm cells of animals, and bacteria, which he described in numerous letters to the Royal Society of London. In 1677, Hooke became Secretary of the Royal Society and, in the same year, confirmed some of Leeuwenhoek's discoveries. The discovery in 2006 of more than 650 pages of Hooke's missing records (the "Hooke Folio") allows us to verify the proceedings of Royal Society meetings and promises to be an important new source of Hooke's views on the renaissance of science in the 17th century.

    2004-05-01

    The existence of microscopic organisms was discovered during the period 1665-83 by two Fellows of The Royal Society, Robert Hooke and Antoni van Leeuwenhoek. In Micrographia (1665), Hooke presented the first published depiction of a microganism, the microfungus Mucor. Later, Leeuwenhoek observed and described microscopic protozoa and bacteria. These important revelations were made possible by the ingenuity of Hooke and Leeuwenhoek in fabricating and using simple microscopes that magnified objects from about 25-fold to 250-fold. After a lapse of more than 150 years, microscopy became the backbone of our understanding of the roles of microbes in the causation of infectious diseases and the recycling of chemical elements in the biosphere.

  17. CRAFTING THE MICROWORLD: HOW ROBERT HOOKE CONSTRUCTED KNOWLEDGE ABOUT SMALL THINGS.

    Science.gov (United States)

    Lawson, Ian

    2016-03-20

    This paper investigates the way in which Robert Hooke constructed his microscopical observations. His Micrographia is justifiably famous for its detailed engravings, which communicated Hooke's observations of tiny nature to his readers, but less attention has been paid to how he went about making the observations themselves. In this paper I explore the relationship between the materiality of his instrument and the epistemic images he produced. Behind the pictures lies an array of hidden materials, and the craft knowledge it took to manipulate them. By investigating the often counter-theoretical and conflicting practices of his ingenious microscope use, I demonstrate the way in which Hooke crafted the microworld for his readers, giving insight into how early modern microscopy was understood by its practitioners and audience.

    2003-01-01

    Robert A. Rankin, one of the world's foremost authorities on modular forms and a founding editor of The Ramanujan Journal, died on January 27, 2001, at the age of 85. Rankin had broad interests and contributed fundamental papers in a wide variety of areas within number theory, geometry, analysis, and algebra. To commemorate Rankin's life and work, the editors have collected together 25 papers by several eminent mathematicians reflecting Rankin's extensive range of interests within number theory. Many of these papers reflect Rankin's primary focus in modular forms. It is the editors' fervent hope that mathematicians will be stimulated by these papers and gain a greater appreciation for Rankin's contributions to mathematics. This volume would be an inspiration to students and researchers in the areas of number theory and modular forms.

    Jonathan Carr-West

    2018-04-01

    Full Text Available Local Government in England: Centralisation, Autonomy and Control is a serious book and an important contribution to the scholarship around local government. It opens however, with a pleasingly comic tableau as academics from England, Portugal and Poland bicker amiably at a conference and on Twitter about whose country is really the most centralised. The rest of the book is devoted to showing why the English academics were right, why it matters and what should be done about it. The main thrust of the text is an analysis of the impact of the dominant policy narratives around centralism and localism. The argument that Copus, Wall and Roberts put forward could be boiled down to the assertion that the problem with local government in England is that it is neither local nor government. But to make this case they first helpfully unpack several sets of concepts that are all too often elided together.

  3. Lessons in power: Lyndon Johnson revealed. A conversation with historian Robert A. Caro.

    2006-04-01

    No one can lead who does not first acquire power, and no leader can be great who does not know how to use that power. The trouble is that the combination of the two skills is rare. Amassing power requires ambition, a focused pragmatism, and a certain ruthlessness that is often at odds with the daring, idealistic vision needed to achieve great things with that power. The tension is as real in business as it is in politics. This magazine is replete with examples of successful senior managers who could not make the switch from ambitious executive to corporate leader because they did not know what to do with the power they had so expertly accumulated. Robert Caro is a student of power. For the past 27 years, the two-time Pulitzer prize-winning biographer of Robert Moses and Lyndon Johnson has focused on the question of how Johnson amassed and wielded power. Caro's deep understanding of the inner workings of power offers senior executives a nuanced picture of leadership at the highest level. In this wide-ranging conversation, Caro shares his insights about the nature of power, the complexity of ambition, and the role that the greater good can play in the making of a leader. Power doesn't always corrupt, he insists. But what it invariably does is reveal a leader's true nature. "Today, when CEOs have acquired more and more power to change our lives," Caro says,"they have become like presidents in their own right, and they, too, need to align themselves with something greater than themselves if they hope to become truly great leaders."

    Full Text Available David Roberts' views of Córdoba were carried out in 1833 and later redrafted as lithographs, engravings, and oils. These artworks enjoyed great commercial success and international diffusion due to their thematic and undoubted artistic value. The authors analyze their documentary value as a graphic record -prior to the advent of photography- of the urban landscape and architecture of Cordoba, a city now denominated a World Heritage Site. These images are studied here for the first time as a group, since they are either virtually untraceable or dispersed in museums throughout the world. In addition, these views have been contextualized with information concerning the artist and his Spanish journey, including a letter that he wrote from Córdoba. The documentary reliability of every image is also assessed, while the significant transformations of the places represented are indicated.Las vistas realizadas en Córdoba por David Roberts en 1833, reelaboradas como litografías, grabados y óleos, han gozado de gran éxito comercial y difusión internacional por su temática e indudable interés artístico. Esta investigación profundiza en su valor documental como registros gráficos previos a la aparición de la fotografía, del paisaje y la arquitectura de una ciudad hoy considerada Patrimonio de la Humanidad. Las imágenes presentadas se analizan por primera vez como conjunto, pues algunas son de difícil localización o están dispersas en museos de todo el mundo, y se contextualizan con datos sobre el pintor y su viaje por España, considerando una carta que éste escribió desde Córdoba. También se valora la fiabilidad documental de cada vista, a la vez que se detectan significativas transformaciones de los lugares representados.

It included system assessment for change readiness, implementation of the algorithm across a 6-week period, evaluation of usefulness by nursing staff, and determination of sustained change at one month. Stakeholder Theory (Friedman and Miles, 2002) and Deming's (1982) Plan-Do-Check-Act Cycle, as adapted by Roberts et al (2010), provided the framework for project implementation. the project was undertaken on a labor and delivery (L&D) unit of a large tertiary care facility in a southwestern state in the USA. The unit had 19 suites with close to 6000 laboring patients each year. full, part-time, and per diem Registered Nurse (RN) staff (N=80), including a subset (n=18) who served as the pilot group and champions for implementing the change. a majority of RNs held a positive attitude toward use of the CWLA to assess laboring women's coping with the pain of labor as compared to a Numeric Rating Scale (NRS). RNs reported usefulness in using the CWLA with patients from a wide variety of ethnicities. A pre-existing well-developed team which advocated for evidence-based practice on the unit proved to be a significant strength which promoted rapid change in practice. this work provides important knowledge supporting use of the CWLA in a large tertiary care facility and an approach for effectively implementing that change. Strengths identified in this project contributed to rapid implementation and could be emulated in other facilities. Participant reports support usefulness of the CWLA with patients of varied ethnicity. Assessment of change sustainability at 1 and 6 months demonstrated widespread use of the algorithm though long-term determination is yet needed. Copyright © 2017 Elsevier Ltd. All rights reserved.

  13. Robert L. Oprisko’s Honor: A Phenomenology and Holden Caulfield

    Directory of Open Access Journals (Sweden)

    Eliza Quincey

    2015-07-01

    Full Text Available Robert L. Oprisko’s book, “Honor: A Phenomenology” challenges ones of the most obvious social norms in contemporary society. The concept of honor is one that the “generic” as Sergei Prozorov would say, simply cannot comprehend, nor even make efforts to define. Though fluently used in infamous works such as “The Iliad”, honor has yet to be so explicitly dissected until now. Dr. Oprisko’s book takes a promiscuous and brutally honest approach to “Honor” en generale as well as the many facets associated with such. Similar to fine cuisine and wine, there are many literary accompaniments that serve as wonderful pairings to broaden the kaleidoscope perspectives presented in the book. The contested novel by J.D. Salinger, “The Catcher in the Rye”, although by no means consists of any political or metaphysical theory, contains a stark personification of what is actively presented in every chapter of Dr. Oprisko’s book. Holden Caufield serves as a terrific litmus test for the concepts defined in Oprisko’s work. Holden is by no means a likeable character in the literary world, but however he is raw enough to be able to internalize and beholden things like, “honorableness”, “dignity”, and most importantly for Holden, “face”. Though to the naked eye and untrained mind these “things” which Holden can in fact internalize may seem fairly simple; it challenges the reader to humble oneself and accept that which is the raw. There is no space for semantics and lies in Oprisko’s work. In fact it is so shockingly explicit, one may find themselves utterly offended. Holden Caufield offended readers for years after Sallinger brought him to life over the span of 200 or more so pages, so much that the book was condemned in certain places. Robert L. Oprisko’s, “Honor: A Phenomenology”, in my utmost opinion, contains this same potential. By critically engaging in Oprisko’s spar with “honor”, one may find themselves

  14. Bookshelf (Conceptual Foundations of Modern Particle Physics, by Robert E. Marshak)

    International Nuclear Information System (INIS)

    Fritzsch, Harald

    1994-01-01

    Particle physics really began as an independent scientific discipline after the Second World War. Robert Marshak was one of its pioneers on the theoretical front, starting out his career with important contributions on meson theory (together with Hans Bethe). The life of Marshak, who died in December 1992, was intimately interwoven with the post-war development of particle physics. His work on weak interaction theory was an important step towards the formulation of the V-A theory, the main pillar on which the modern electroweak theory rests erected. He is also remembered as the founder of the biennial 'Rochester' conference series (March 1993, page 24). Just before his death Robert Marshak finished writing his book on the concepts of particle physics. The book starts out with an historical account of the development of the field. He divides it into the startup period (1945-60) - the period of meson physics, the physics of strange particles, parity violation etc; the heroic period (1960-1975) when the Standard Model of the electroweak and strong interactions was developed; and finally the period of consolidation and speculation (since 1975). Marshak's recollection of the development of particle physics represents a personal view, worth reading by young researchers, although it does not attempt to provide a complete picture. After the historical chapter Marshak introduces the reader to the basics of quantum field theory (space-time symmetries, global internal symmetries and their breaking, gauge symmetries). Later he turns to a description of QCD and the gauge theory of the electroweak interactions. A whole chapter is devoted to the problems related to anomalies. In the last part of the book Marshak discusses various hypotheses of unifying the strong and electroweak interactions, especially the various facets of the SO(10) theory, followed by a long discussion of the fermion generation problem and of preon models. The book concludes with an extensive

    Managing diversity dynamics in academic or clinical settings for men in nursing has unique challenges resulting from their minority status within the profession. The purpose of this study was to share challenges and lessons learned identified by male scholars in the Robert Wood Johnson Foundation Nurse Faculty Scholars program and suggest strategies for creating positive organizations promoting inclusive excellence. Multiple strategies including informal mentored discussions and peer-to-peer dialogue throughout the program, formal online surveys of scholars and National Advisory Committee members, and review of scholar progress reports were analyzed as part of the comprehensive evaluation plan of the program. Diversity dynamic issues include concerns with negative stereotyping, microaggression, gender intelligence, and differences in communication and leadership styles. Male nurse faculty scholars report experiencing both opportunities and challenges residing in a predominately female profession. This article attempts to raise awareness and suggest strategies to manage diversity dynamics in service of promoting the development of a culture of health that values diversity and inclusive excellence for both men and women in academic, research, and practice contexts.

  18. The two faces of Robert Fitzroy, Captain of HMS Beagle and governor of New Zealand.

    Paul, Diane B; Stenhouse, John; Spencer, Hamish G

    2013-09-01

    Robert FitzRoy, Captain of HMS Beagle and second governor of New Zealand, has two contradictory reputations among modern academics. Evolutionary biologists and Darwin scholars generally view FitzRoy as a supporter of slavery, famously quarrelling with the abolitionist Darwin over that topic during a Brazilian stopover early in the voyage of HMS Beagle. He is also regarded as a political and religious reactionary, taking a biblically creationist position at the infamous 1860 Oxford meeting of the British Association for the Advancement of Science. New Zealand historians, however, view his record as governor much more positively. They emphasize that FitzRoy was wildly unpopular with the British settlers because of his enlightened insistence that the native Maori should be treated fairly. We outline the history of these seemingly inconsistent views and examine the evidence for each. We conclude by suggesting that a more nuanced account of FitzRoy's career would surely be more thought-provoking as well as respectful of the facts.

    2013-01-01

    Kathleen Kaska has done a remarkable job of capturing the life of Robert Porter Allen, truly one of the premier biologist/conservationists of the twentieth century. Allen, born in 1905, grew up reading outdoor adventure books and playing in the woods of northern Pennsylvania with his brother. At a young age, he was encouraged to join the Junior Audubon club and his passion for ornithology soon crystallized. He attended Lafayette College to study ornithology, but he was disinterested in academics and fared poorly. He dropped out after two years and joined the Merchant Marines. Not an auspicious beginning for such a highly respected scientist and conservationist! Soon, however, he landed a librarian job with Audubon and his diligence, acumen, and communication skills allowed him to take more and more responsibilities. He became one of the youngest Audubon sanctuary directors ever appointed, and he was also able to secure a fellowship through Cornell to work on Roseate Spoonbills (Platalea ajaja). Audubon later appointed him to lead their Whooping Crane (Grus americana) studies.

  20. Robert Plant (1818–1858: A Victorian plant hunter in Natal, Zululand, Mauritius and the Seychelles

    Directory of Open Access Journals (Sweden)

    Donal P. McCracken

    2011-03-01

    Full Text Available In the 1850s Robert William Plant collected plants and other natural specimens in what is now KwaZulu-Natal. This one-time Englishman compiled a dictionary for gardeners before emigrating to Natal in 1850. There he worked as the agent for Samuel Stevens, the London dealer in ‘curiosities of natural history’. Though Plant collected mainly plants, he also sent consignments of beetles, butterflies, bird skins and shells back to Britain. He published the first scientific paper on Zululand and was requested by the Royal Botanic Gardens at Kew to write the first Flora natalensis. It was while collecting for this never-to-be-completed treatise that Plant contracted malaria in Maputaland. He died in St Lucia in 1858 and in doing so became South Africa’s martyr to botany. What emerges from this study is a picture of the difficulties faced by plant hunters in mid-19th-century South Africa, the sort of plants they collected and the necessity for them sometimes to diversify into other natural history products to survive.

  1. A capital Scot: microscopes and museums in Robert E. Grant's zoology (1815-1840).

    Science.gov (United States)

    Quick, Tom

    2016-06-01

    Early nineteenth-century zoology in Britain has been characterized as determined by the ideological concerns of its proponents. Taking the zoologist Robert E. Grant as an exemplary figure in this regard, this article offers a differently nuanced account of the conditions under which natural-philosophical knowledge concerning animal life was established in post-Napoleonic Britain. Whilst acknowledging the ideological import of concepts such as force and law, it points to an additional set of concerns amongst natural philosophers - that of appropriate tool use in investigation. Grant's studies in his native Edinburgh relied heavily on the use of microscopes. On his arrival in London, however, he entered a culture in which a different set of objects - museum specimens - held greater persuasive power. This article relates changes in Grant's ideas and practices to the uneven emphases on microscopic and museological evidence amongst European, Scottish and English natural philosophers at this time. In so doing, it identifies the reliance of London-based natural philosophers on museology as constituting a limiting effect on the kinds of claim that Grant sought to make regarding the nature of life.

    Roberts syndrome and SC phocomelia (RBS/SC) are genetic autosomal recessive syndromes caused by establishment of cohesion 1 homolog 2 ( ESCO 2) mutation. RBS/SC appear to have a variety of clinical features, even with the same mutation of the ESCO2 gene. Here, we established and genetically characterized a medaka model of RBS/SC by reverse genetics. The RBS/SC model was screened from a mutant medaka library produced by the Targeting Induced Local Lesions in Genomes method. The medaka mutant carrying the homozygous mutation at R80S in the conserved region of ESCO2 exhibited clinical variety (i.e. developmental arrest with craniofacial and chromosomal abnormalities and embryonic lethality) as characterized in RBS/SC. Moreover, widespread apoptosis and downregulation of some gene expression, including notch1a, were detected in the R80S mutant. The R80S mutant is the animal model for RBS/SC and a valuable resource that provides the opportunity to extend knowledge of ESCO2. Downregulation of some gene expression in the R80S mutant is an important clue explaining non-correlation between genotype and phenotype in RBS/SC. © 2012 The Authors Development, Growth & Differentiation © 2012 Japanese Society of Developmental Biologists.

  3. The relation between creation and salvation in the Trinitarian theology of Robert Jenson

    Directory of Open Access Journals (Sweden)

    Anné H. Verhoef

    2013-02-01

    Full Text Available This article explored the relation between creation and salvation as acts of God in the theology of Robert Jenson, an American Lutheran theologian. This is important due to Jenson’s growing importance as theologian and because of the current importance of ecotheology (and related themes that were implicated by the relation between creation and salvation. Jenson’s theology is an effort to tell God’s particular story and it can be described as a Trinitarian, narrative and eschatological theology. His starting point is that God’s eternity must not be understood as timeless (this is unbiblical and incompatible with the story of creation and redemption and that creation (space and time takes place somehow within the being of God. Jenson qualified this ‘withinness’, but also emphasised that creation is an intelligible whole, a history with an intended end. It is important for him that God’s story – a story of dramatic coherence – is not separated from our own and creation’s story. Within this understanding of God’s story (as dramatic coherence, creation found its own dramatic teleology because salvation also includes creation. Creation is therefore not subjected to pointlessness any longer, but will find its final place within God. The implication of this is that we must value creation much more and act with more responsibility towards it. According to Jenson we must enjoy creation in an aesthetic fashion and delight in creation as a whole because of its dramatic teleology.

  4. A Staged Reading of the Play: TRANSCENDENCE: Relativity and Its Discontents by Robert Marc Friedman

    Friedman, Robert Marc

    2015-04-01

    TRANSCENDENCE explores aspects of Einstein's life and his general theory of relativity at the time of the theory's creation and initial reception. While being faithful to historical scholarship, the play creates its own theatrical reality aiming to engage emotions and intellect. Those who strive for transcendence must nevertheless also confront the harsh realities of living in specific time-bound social contexts. Universal constants that anchor physical theory in an objective reality, as Einstein believed, do not readily have equivalents in notions of identity, duty, loyalty, and excellence. In November 1915 after toiling for years in Zurich, Prague, and now Berlin, Einstein achieved his general theory of relativity. When in 1919 British astronomers announced evidence for the bending of starlight by the sun as Einstein had predicted, he soon surprisingly found himself an international celebrity. Expectations arose that he would be called to Stockholm. But the Nobel Committee for Physics refused to acknowledge ``speculations'' such Einstein's. The dismissal of relativity entailed principled and biased opposition, and not simply mistakes in evaluation. Several committee members agreed that Einstein must not receive a Prize. Join us for a dramatic staged reading of TRANSCENDENCE, a play by the science historian Robert Marc Friedman (http://www.hf.uio.no/iakh/english/people/aca/robertfr/index.html) and directed by James Glossman, Lecturer in Directing and Shakespeare, Johns Hopkins University. After the performance, the playwright, director and actors will be available for a talk-back audience discussion.

  5. Diagnostic Overlap between Fanconi Anemia and the Cohesinopathies: Roberts Syndrome and Warsaw Breakage Syndrome

    Directory of Open Access Journals (Sweden)

    Petra van der Lelij

    2010-01-01

    Full Text Available Fanconi anemia (FA is a recessively inherited disease characterized by multiple symptoms including growth retardation, skeletal abnormalities, and bone marrow failure. The FA diagnosis is complicated due to the fact that the clinical manifestations are both diverse and variable. A chromosomal breakage test using a DNA cross-linking agent, in which cells from an FA patient typically exhibit an extraordinarily sensitive response, has been considered the gold standard for the ultimate diagnosis of FA. In the majority of FA patients the test results are unambiguous, although in some cases the presence of hematopoietic mosaicism may complicate interpretation of the data. However, some diagnostic overlap with other syndromes has previously been noted in cases with Nijmegen breakage syndrome. Here we present results showing that misdiagnosis may also occur with patients suffering from two of the three currently known cohesinopathies, that is, Roberts syndrome (RBS and Warsaw breakage syndrome (WABS. This complication may be avoided by scoring metaphase chromosomes—in addition to chromosomal breakage—for spontaneously occurring premature centromere division, which is characteristic for RBS and WABS, but not for FA.

    2008-11-25

    Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

    The history of psychosurgery is filled with tales of researchers pushing the boundaries of science and ethics. These stories often create a dark historical framework for some of the most important medical and surgical advancements. Dr. Robert G. Heath, a board-certified neurologist, psychiatrist, and psychoanalyst, holds a debated position within this framework and is most notably remembered for his research on schizophrenia. Dr. Heath was one of the first physicians to implant electrodes in deep cortical structures as a psychosurgical intervention. He used electrical stimulation in an attempt to cure patients with schizophrenia and as a method of conversion therapy in a homosexual man. This research was highly controversial, even prior to the implementation of current ethics standards for clinical research and often goes unmentioned within the historical narrative of deep brain stimulation (DBS). While distinction between the modern practice of DBS and its controversial origins is necessary, it is important to examine Dr. Heath's work as it allows for reflection on current neurosurgical practices and questioning the ethical implication of these advancements.

  9. Essay: Robert H. Siemann As Leader of the Advanced Accelerator Research Department

    Energy Technology Data Exchange (ETDEWEB)

    Colby, Eric R.; Hogan, Mark J.; /SLAC

    2011-11-14

    Robert H. Siemann originally conceived of the Advanced Accelerator Research Department (AARD) as an academic, experimental group dedicated to probing the technical limitations of accelerators while providing excellent educational opportunities for young scientists. The early years of the Accelerator Research Department B, as it was then known, were dedicated to a wealth of mostly student-led experiments to examine the promise of advanced accelerator techniques. High-gradient techniques including millimeter-wave rf acceleration, beam-driven plasma acceleration, and direct laser acceleration were pursued, including tests of materials under rf pulsed heating and short-pulse laser radiation, to establish the ultimate limitations on gradient. As the department and program grew, so did the motivation to found an accelerator research center that brought experimentalists together in a test facility environment to conduct a broad range of experiments. The Final Focus Test Beam and later the Next Linear Collider Test Accelerator provided unique experimental facilities for AARD staff and collaborators to carry out advanced accelerator experiments. Throughout the evolution of this dynamic program, Bob maintained a department atmosphere and culture more reminiscent of a university research group than a national laboratory department. His exceptional ability to balance multiple roles as scientist, professor, and administrator enabled the creation and preservation of an environment that fostered technical innovation and scholarship.

    Full Text Available Spare Parts (spareparts.exchange is an art installation created collaboratively by Heather Dewey-Hagborg, Jim Ruxton, Camille Turner, and Monir Moniruzzaman. Based on Monir Moniruzzaman’s ethnographic research on the illicit organ trade, Spare Parts explores the ethics of organ trafficking and the emergence of bodily inequality in times of transplant tinkering. In this installation, the viewer is confronted with life sized video projections of Rahim Sheikh, a Bangladeshi kidney seller and Robert Zurrer, a Canadian kidney transplant recipient/buyer, whose kidneys were commodified in the marketplace. The video projections are installed so that the individuals sit in silence facing each other.  Spare Parts highlights the intimacy of spare parts, the economy of the global marketplace, the perils of techno-medicine, and what is means to be human in the 21st century. The installation captures that the buying and selling of body parts is not just a market transaction, but rather represents the desperation, dis/connection, and inequality that exists in the trade.

    Robert Graves is a poet-mythographer, well-known in the U. K. and the U. S. A., but not in Japan despite his huge amount of poetic, mythographical, prose and critical works. Furthermore, even in the U. S. A. and the U. K., some people have been shunning him politely as a versatile iconoclast possessed of the White Goddess. In fact, it is not difficult to imagine that when King Jesus, a life story of Christ, was published, people were shocked at his extraordinary mythographical Christology derived from his enthusiasm towards the White Goddess Cult. In Christ he discovered the fragments of maternal doctrine as a new concept in opposition to the Apollonian theory of Judaism, but they seemed to be quite incomplete in the author's eyes lacking in something most essential in life, recognition of love and hatred discipline. This paper is an inquiry into how the author developed his own hermaneutics of Christ through his wide and thorough scholarship on mythology, history, the Bible and Celtic poetry.

    The Robert Wood Johnson Foundation Nurse Faculty Scholars program was created to address the nursing faculty shortage and thereby decrease the nursing shortage. The purpose of the study was to describe the program development, implementation, and ongoing outcome evaluation. Data on scholarly productivity, impact of research, research funding, and leadership positions were compiled, including an h-index (impact of publications) comparison with a comparison group of other interdisciplinary faculty at the same institutions of the 90 current and alumni scholars. There is evidence of the achievements of the individual scholars; however, the effect of the synergy of the multiple components of the program is difficult to capture in traditional evaluation strategies. The sense of possibility and responsibility (to the profession, to improving the health of all Americans, and to one's school of nursing and university) was a significant outcome of the program. Lessons learned from the program are important for the leadership development and retention of nursing faculty. Copyright © 2017 Elsevier Inc. All rights reserved.

The basic premise is that Kurt Lewin's field-theoretical psychology played a crucial role in the development of behavioral self-regulation concepts. The goal is to show (1) that Lewin's early experiments and theories were based on the idea of a dynamic process of self-regulation determined by the actors and their personal motivation and interaction, (2) that this concept of self-regulation functioned as a camouflage for power-strategies that aimed to regulate and optimize the economic production and social reproduction processes, (3) that in Robert Musil's fragmentary, 'fringing' novel The Man without Qualities the attempt to optimize the social and economic behavior and to establish a homeostatic state proved to be a complete failure. As a notable result, this 'literary test' of behavioral self-regulation revealed the violence and imbalance of power inherent in this concept of self-regulation and its practical implementation.

    The Robert Wood Johnson (RWJ) Foundation initiated Turning Point in collaboration with the W.K. Kellogg Foundation (Kellogg) in 1997. The purpose of this major national initiative was to strengthen the public health infrastructure in the United States so that states, local communities, and their public health agencies might respond to the challenge to protect and improve the public's health in the 21st century. RWJ funded 21 states and Kellogg funded 43 communities to work together to create a new way of thinking about how health could be improved and who should be involved. Although the ultimate outcome was to improve health, both foundations expected diverse partnerships to work together to create strategic health improvement plans at both the community and state levels. The foundations funded a variety of strategies within those health improvement plans during an implementation phase. The premise in funding partnerships, as opposed to a single entity, was that effective public health systems would be developed best through a shared responsibility (including the private sector) for the health of a community.

    To analyze the prevalence, cause, treatment, and risk factors of severe post-partum hemorrhage (transfusion, surgery, radiology) observed at the maternity ward of the Robert-Debré Hospital, Paris. Method. This retrospective cohort was collected from a database including 19182 deliveries from 1992 to 1998. The entire medical file was reviewed in cases of severe hemorrhage. The prevalence of severe post-partum hemorrhage was 23 per 10,000 deliveries (44 patients). Transfusion was performed in 44/44 and hysterectomy in 3/44. Three patients were transferred to the intensive care unit. There were no deaths. At multivariate analysis, risk factors for severe post-partum hemorrhage were: abnormal placental insertion (OR=7.2; 95CI: 2.18-18.3), cesarean (OR=5.8; 95CI: 2.9-11.6), multiple pregnancy (OR=3.2; 95CI: 1.3-7.8), prematurity (OR=3, 95CI: 1.5-6.2), hypertension (OR=2.9; 95CI: 1.3-6.3). Twenty-six percent of the patients had no risk factors. The prevalence of severe pot-partum hemorrhage is low in our experience. The methodology used for this retrospective cohort does not enable an explanation. Intensive obstetrical care is necessary in case of abnormal placenta insertion. In 10 out of 44 cases, severe post-partum hemorrhage occurred in a context of insufficient monitoring, late or erroneous diagnosis, or incorrect treatment.

  16. Robert Dicke and the naissance of experimental gravity physics, 1957-1967

    2017-06-01

    The experimental study of gravity became much more active in the late 1950s, a change pronounced enough be termed the birth, or naissance, of experimental gravity physics. I present a review of developments in this subject since 1915, through the broad range of new approaches that commenced in the late 1950s, and up to the transition of experimental gravity physics to what might be termed a normal and accepted part of physical science in the late 1960s. This review shows the importance of advances in technology, here as in all branches of natural science. The role of contingency is illustrated by Robert Dicke's decision in the mid-1950s to change directions in mid-career, to lead a research group dedicated to the experimental study of gravity. The review also shows the power of nonempirical evidence. Some in the 1950s felt that general relativity theory is so logically sound as to be scarcely worth the testing. But Dicke and others argued that a poorly tested theory is only that, and that other nonempirical arguments, based on Mach's Principle and Dirac's Large Numbers hypothesis, suggested it would be worth looking for a better theory of gravity. I conclude by offering lessons from this history, some peculiar to the study of gravity physics during the naissance, some of more general relevance. The central lesson, which is familiar but not always well advertised, is that physical theories can be empirically established, sometimes with surprising results.

  17. Essay: Robert H. Siemann As Leader of the Advanced Accelerator Research Department

    2008-01-01

    Robert H. Siemann originally conceived of the Advanced Accelerator Research Department (AARD) as an academic, experimental group dedicated to probing the technical limitations of accelerators while providing excellent educational opportunities for young scientists. The early years of the Accelerator Research Department B, as it was then known, were dedicated to a wealth of mostly student-led experiments to examine the promise of advanced accelerator techniques. High-gradient techniques including millimeter-wave rf acceleration, beam-driven plasma acceleration, and direct laser acceleration were pursued, including tests of materials under rf pulsed heating and short-pulse laser radiation, to establish the ultimate limitations on gradient. As the department and program grew, so did the motivation to found an accelerator research center that brought experimentalists together in a test facility environment to conduct a broad range of experiments. The Final Focus Test Beam and later the Next Linear Collider Test Accelerator provided unique experimental facilities for AARD staff and collaborators to carry out advanced accelerator experiments. Throughout the evolution of this dynamic program, Bob maintained a department atmosphere and culture more reminiscent of a university research group than a national laboratory department. His exceptional ability to balance multiple roles as scientist, professor, and administrator enabled the creation and preservation of an environment that fostered technical innovation and scholarship.

    Transdermal drug delivery continues to provide an advantageous route of drug administration over injections. While the number of drugs delivered by passive transdermal patches has increased over the years, no macromolecule is currently delivered by the transdermal route. Substantial research efforts have been dedicated by a large number of researchers representing varied disciplines including biology, chemistry, pharmaceutics and engineering to understand, model and overcome the skin's barrier properties. This article focuses on engineering contributions to the field of transdermal drug delivery. The article pays tribute to Prof. Robert Langer, who pioneered the engineering approach towards transdermal drug delivery. Over a period spanning nearly 25 years since his first publication in the field of transdermal drug delivery, Bob Langer has deeply impacted the field by quantitative analysis and innovative engineering. At the same time, he has inspired several generations of engineers by collaborations and mentorship. His scientific insights, innovative technologies, translational efforts and dedicated mentorship have transformed the field. © 2013 S. Karger AG, Basel.

    The reproduction of a San Joaquin kit fox population (Vulpes velox macrotis) was investigated at Camp Roberts Army National Guard Training Site, California, from November 1988 through September 1991. Of 38 vixens radiocollared prior to parturition, 12 (32%) were successful in raising pups from conception to the point where pups were observed above ground. No yearling vixens were known tb be reproductively active. The mean litter size during 1989 - 1991 was 3.0 (n = 21, SE = 0.28) and ranged from one to six pups. Both the proportion of vixens successfully raising pups and the mean litter size observed at Camp Roberts during this study were lower than those reported at other locations. Sex ratios of kit fox pups were male biased two of the three years, but did not differ statistically from 1:1 throughout the study. Whelping was estimated to occur between February 15 and March 5. Results of this study support previous reports that kit foxes are primarily monogamous, although one case of polygamy may have occurred. Both the proportion of dispersing radiocollared juveniles (26%) and the mean dispersal distance (5.9 km) of juveniles at Camp Roberts appeared low compared to other locations

  2. From Notebook to Novel and from Diary to Dante: Reading Robert Dessaix’s Night Letters

    Full Text Available This paper has developed out of a larger work in progress, which focuses on representations of Italy in contemporary Australian fiction and non-fiction prose. This larger project aims to add to an established body of work on travel writing by considering Australian texts that describe Australian travel in Italy, Italian people and Italian places. In this paper, I will specifically focus on the representations of Italy in Robert Dessaix’s novel Night Letters (1996. My paper will explore the relationship between the writer’s actual journey in Italy and that of the creative work’s main character. The novel offers the protagonist’s account in the form of letters, which describe his travel from Switzerland across Northern Italy to Venice. I will begin by briefly outlining the Italian itinerary followed by Dessaix that would eventually inspire the novel. I will then explore the relationship between Dessaix’s notebooks recording his two journeys in Italy and the literary accomplishment of Night Letters. My aim is to show ways in which an itinerary becomes a story, a complex narrative. Reference will be made to factual accounts and descriptions in the author’s own diaries with an analysis of their generative role as key sources for the fictional work. This will be done through a close reading of particular passages, in the diaries and in the novel, concerning the same event. A comparative analysis of the notebooks and Night Letters can show that Dessaix’s diary entries relating to Italian places are woven into the fictional fabric of the ‘night letters’ according to a unifying principle.

    The Robert Wood Johnson Foundation Nurse Faculty Scholars (RWJF NFS) program was developed to enhance the career trajectory of young nursing faculty and to train the next generation of nurse scholars. Although there are publications that describe the RWJF NFS, no evaluative reports have been published. The purpose of this study was to evaluate the first three cohorts (n = 42 scholars) of the RWJF NFS program. A descriptive research design was used. Data were derived from quarterly and annual reports, and a questionnaire (seven open-ended questions) was administered via Survey Monkey Inc. (Palo Alto, CA, USA). During their tenure, scholars had on average six to seven articles published, were teaching/mentoring at the graduate level (93%), and holding leadership positions at their academic institutions (100%). Eleven scholars (26%) achieved fellowship in the American Academy of Nursing, one of the highest nursing honors. The average ratings on a Likert scale of 1 (not at all supportive) to 10 (extremely supportive) of whether or not RWJF had helped scholars achieve their goals in teaching, service, research, and leadership were 7.7, 8.0, 9.4, and 9.5, respectively. The majority of scholars reported a positive, supportive relationship with their primary nursing and research mentors; although, several scholars noted challenges in connecting for meetings or telephone calls with their national nursing mentors. These initial results of the RWJF NFS program highlight the success of the program in meeting its overall goal-preparing the next generation of nursing academic scholars for leadership in the profession.

    The rare, autosomal recessive Roberts syndrome (RBS) is characterized by tetraphocomelia, profound growth deficiency of prenatal onset, craniofacial anomalies, microcephaly, and mental deficiency. SC phocomelia (SC) has a milder phenotype, with a lesser degree of limb reduction and with survival to adulthood. Since heterochromatin repulsion (HR) is characteristic for both disorders and is not complemented in somatic-cell hybrids, it has been hypothesized that the disorders are allelic. Recently, mutations in ESCO2 (establishment of cohesion 1 homolog 2) on 8p21.1 have been reported in RBS. To determine whether ESCO2 mutations are also responsible for SC, we studied three families with SC and two families in which variable degrees of limb and craniofacial abnormalities, detected by fetal ultrasound, led to pregnancy terminations. All cases were positive for HR. We identified seven novel mutations in exons 3-8 of ESCO2. In two families, affected individuals were homozygous--for a 5-nucleotide deletion in one family and a splice-site mutation in the other. In three nonconsanguineous families, probands were compound heterozygous for a single-nucleotide insertion or deletion, a nonsense mutation, or a splice-site mutation. Abnormal splice products were characterized at the RNA level. Since only protein-truncating mutations were identified, regardless of clinical severity, we conclude that genotype does not predict phenotype. Having established that RBS and SC are caused by mutations in the same gene, we delineated the clinical phenotype of the tetraphocomelia spectrum that is associated with HR and ESCO2 mutations and differentiated it from other types of phocomelia that are negative for HR.

  6. Projecting Dynastic Majesty: State Ceremony in the Reign of Robert Bruce

    2015-07-01

    Full Text Available Following the murder of his rival John Comyn on 10 February at Greyfriars in Dumfries, and the crisis this act incited, Robert the Bruce’s inaugural ceremony took place at Scone in late March 1306. Much about this ceremony is speculative; however, subsequent retrospective legitimisation of the Bruce claims to the royal succession would suggest that all possible means by which Robert’s inauguration could emulate his Canmore predecessors and outline his right to rule on a level playing field with his contemporaries were amplified, particularly where they served the common purpose of legitimising Robert’s highly questioned hold on power. Fourteenth-century Scottish history is inextricably entwined in the Wars of Independence, civil strife and an accelerated struggle for autonomous rule and independence. The historiography of this period is unsurprisingly heavily dominated by such themes and, while this has been offset by works exploring subjects such as the tomb of Bruce and the piety of the Bruce dynasty, the ceremonial history of this era remains firmly in the shadows. This paper will address three key ceremonies through which a king would, traditionally, make powerful statements of royal authority: the inauguration or coronation of Bruce; the marriage of his infant son to the English princess Joan of the Tower in 1328, and his extravagant funeral ceremony in 1329. By focusing thus this paper hopes to shed new light on the ‘dark and drublie days’ of fourteenth-century Scotland and reveal that glory, dynastic majesty and pleasure were as central to the Scottish monarchy in this era as war and political turbulence.

    Full Text Available Robert Seymour was celebrated enough in his day to become one of very few late Regency and early Victorian comic and satirical draughtsmen sufficiently visible to be traced through the magazines of the 1830s. His periodical contributions are, therefore, of considerable significance in trying to establish the patterns of work and maps of interconnected activity that were necessary to sustain the career of a jobbing draughtsman at this time. After contributing to Bell’s Life in London in the late 1820s, Seymour’s presence as a prolific magazine illustrator dates largely from the early 1830s. As well as a mass of jobbing illustrations that were produced for a remarkably diverse range of magazines. Seymour worked extensively for three significant and profusely illustrated magazines at this time — the Looking Glass, Figaro in London, and the Comic Magazine. The Looking Glass was published by Thomas McLean and sought to sustain an established tradition of political caricature through adapting it to a magazine format using the relatively new reprographic medium of lithography. Figaro in London was illustrated by vignette wood engravings, which were both vernacular and sophisticated at the same time. The Comic Magazine, another publication dependent on small wood-engraved images, sought to build on the growing popularity of song books and comic annuals. The diversity and prolixity of Seymour’s output at this time bears testimony to the extraordinary demands made on draughtsmen and engravers in the 1830s, and suggests something of the relentlessly innovative market place for humorous and satirical print at this time.

  8. An experimental 'Life' for an experimental life: Richard Waller's biography of Robert Hooke (1705).

    Moxham, Noah

    2016-03-01

    Richard Waller's 'Life of Dr Robert Hooke', prefixed to his edition of Hooke's Posthumous Works (1705), is an important source for the life of one of the most eminent members of the early Royal Society. It also has the distinction of being one of the earliest biographies of a man of science to be published in English. I argue that it is in fact the first biography to embrace the subject's natural-philosophical work as the centre of his life, and I investigate Waller's reasons for adopting this strategy and his struggle with the problem of how to represent an early experimental philosopher in print. I suggest that Waller eschews the 'Christian philosopher' tradition of contemporary biography - partly because of the unusually diverse and fragmentary nature of Hooke's intellectual output - and draws instead upon the structure of the Royal Society's archive as a means of organizing and understanding Hooke's life. The most quoted phrase from Waller's biography is that Hooke became 'to a crime close and reserved' in later life; this essay argues that Waller's biographical sketch was fashioned in order to undo the effects of that reserve. In modelling his approach very closely on the structure of the society's records he was principally concerned with making Hooke's work and biography accessible, intelligible and useful to the fellowship in a context familiar to them, a context which had provided the institutional framework for most of Hooke's adult life. I argue that Waller's 'Life' was also intended to make the largest claims for Hooke's intellectual standing that the author dared in the context of the enmity between Hooke and Isaac Newton once the latter became president of the Royal Society. However, I also adduce fresh manuscript evidence that Waller actually compiled, but did not publish, a defence of Hooke's claim to have discovered the inverse square law of gravity, allowing us to glimpse a much more assertive biography of Hooke than the published version.

  9. Deficit or creativity: Cesare Lombroso, Robert Hertz, and the meanings of left-handedness.

    Science.gov (United States)

    Kushner, Howard I

    2013-01-01

    In the first decade of the twentieth century two influential researchers attempted to explain the origin and impact of left-handedness in human history. The first, the Turin physician Cesare Lombroso, often referred to as the father of modern criminology, was nearing the end of his long distinguished career. Lombroso tied left-handedness to criminality, insanity, and feeble mindedness. According to Lombroso, these groups shared biological regressions to primitive mentalities that could not be reversed by education or training. The second, French sociologist Robert Hertz, was at the beginning of a career cut short by his death in combat during the First World War. Hertz challenged Lombroso's claims, insisting that the predominance of right-handedness, whatever its biological substrate, was ultimately a cultural artefact driven by a primitive human urge to make sense of the world by dividing it into binary oppositions in which the right was viewed as sacred and the left as profane. Ending discrimination against left-handedness would, according to Hertz, unleash access to both hands and thus both hemispheres. The results, he insisted, would allow repressed talents and creativity to flourish. The conflicting views of Lombroso and Hertz have informed investigations of the causes and consequences of left-handedness until today. While the language of the debate has been reframed in current scientific discourses, left-handedness continues to be portrayed in the contradictory ways first elaborated by Lombroso and Hertz more than a century ago as either the cause of a variety of learning disabilities or as the key that can unlock creativity and talent. The debate also exposed the extent to which other cultural concerns, particularly anti-Semitism, informed theories of handedness.

    Full Text Available The present paperwork aimed to analyse whether or not the publication of a biography should require the prior authorisation from the subject  or their family. As there is, in this case, a collision between personality rights and freedom of speech, the proportionality test was used to solve such conflict. The first step was to define biography as a non-ficctional genre. The paperwork then aimed to define the theory of the principles, the external theory of the restriction of fundamental rights and the proportionality test developed by jurist Robert Alexy, which are largely used in Brazil by authors like Virgílio Afonso da Silva, Ingo Wolfgang Sarlet and Daniel Sarmento. It was observed that when fundamental rights collide, the proportionality must be verified and as a result there is a conditional precedence relation between the rights. In such case, the ceding right will be restricted by the preciding one. The external theory is a recognised manner of verifying whether the restriction of a fundamental right is legit or if it is a violation. The need for prior authorisation, based on the personality protection, restricts freedom of speech, on the other hand, its exemption is based on the right to freedom of speech. By applying the aforementioned method, a particular rule was developed and the conditions for it to be applicable: freedom of speech prevails over personality rights in given conditions (public figure, over suitable means, no expectation for privacy in the publication, diligence in the verification of truth or social and journalistic interest over the information

  11. Robert Burns and the Re-making of National Memory in Contemporary Scotland

    2012-05-01

    Full Text Available Robert Burns, the eighteenth-century Scottish poet and song writer, continues to maintain a substantial cultural ‘afterlife’ in the twenty first century, both within Scotland and beyond. Achieving cult status in the nineteenth century, the power of Burns as a popular cultural icon remains undiminished. Where the appropriation of Burns as national icon in the nineteenth century was made manifest in statuary, commemorative objects, and painted portraits, the twenty-first century has been marked by the proliferation of the image of Burns in new forms and technologies, with Burns as product and brand logo, museum and heritage attraction, and tourism industry selling point. This recent flourishing of interest and engagement raises questions about why and how an eighteenth-century poet continues to be the object of such extensive cultural elaboration at this time. In approaching this question, some fruitful lines of enquiry are being suggested in recent discussions that have looked at the nineteenth-century Burns as a ‘mobilizing agent in collective memory production’ (Rigney 2011, 81. One such appraisal points to how the construction of Burns in the nineteenth century as an iconic figure of Scottish cultural memory has the potential to ‘be resignified as necessary in subsequent chronological and geographical sites’ (Davis 2010, 14. It is this potential for the resignification of Burns as a symbolic site for the nation’s memory that this paper explores. In pointing to Burns’ representation in a variety of popular forms and in public discourse, the paper examines how a writer comes to be invested and reinvested as the voice and persona of the nation.

    Full Text Available Este artigo procura investigar a leitura que o arquiteto Robert Venturi faz de alguns traços da obra de Le Corbusier, para conceber suas considerações sobre arquitetura e comunicação. Para isso, foram estudadas, de modo breve, as maneiras como Le Corbusier já fazia uso, em sua obra, de algumas categorias que, posteriormente, seriam atribuídas, excelentemente, aos ditos pós-modernos: a retórica, a alusão, a memória dos centro históricos e dos interiores decorados. Tendo em vista a obra geral do arquiteto suíço, é certo que essas categorias aparecem somente nas entrelinhas de seu projeto modernista de reorganização das cidades. Entretanto, uma leitura de minúcias revela alguns temas – especificamente o interesse de Corbusier nos monumentos de Paris, seus pórticos desenhados na Ville contemporaine (1921, e a lareira com motivos surrealistas na cobertura De Beistegui (1929 que seriam objeto de pleno interesse para historiadores e arquitetos da década de 1960. Justamente, nessa recuperação de traços obscuros de Corbusier, Venturi posiciona alguns de seus temas, especificamente em suas soluções residenciais, privilegiando – e, em alguns casos, mesmo exagerando, a imagem chaminé, duplicando sua altura ou colocando-a como grande ordenadora da planta. Todo esse debate será estudado tendo, como pano de fundo, escritos recentes que realizam um balanço crítico das rupturas engendradas pela dita arquitetura pós-moderna com os modernismos. Fazendo uso de considerações de Andreas Huyssen, Paul Virilio e Beatriz Colomina, entre outros, procurou-se ora delimitar, com maior clareza, a fronteira entre essas duas correntes do século 20, ora diluir seus contornos, revelando semelhanças que, eventualmente, fazem-nas indissociáveis.

  18. Distribution and origin of authigenic smectite clays in Cape Roberts Project Core 3, Victoria Land Basin, Antarctica

    Of some 800 m of lower Oligocene marine sediments cored continuously from the seafloor in the Victoria Land Basin of Antarctica at Cape Roberts Site CRP-3, the lower 500 m exhibit authigenic smectite clay coats on shallow-water sandstone grains. A scanning electron microscope/EDS study of 46 fracture sections confirms that the distribution of the clay coats through the unit is not uniform or evenly distributed, but rather varies with depth, original porosity, and the kinds and abundance of source materials. Our results suggest that smectite emplacement resulted from in-situ, low-temperature burial diagenesis rather than hydrothermal or fault-focused thermobaric fluids.

    Mentoring has long been regarded as one of the key components of research training and faculty development. The Robert Wood Johnson Foundation Nurse Faculty Scholars program purposely facilitated scholars' development of a mentoring network by providing each individual with three mentors: a school-of-nursing mentor (primary), a university-based non-nurse research mentor (research), and a nationally-recognized nurse leader at another university (national). The Mentorship Effectiveness Scale was used to assess the effectiveness of each type of mentor in the first five completed cohorts. The ratings of mentorship effectiveness for all three kinds of mentors were generally high. Scholars valued most their mentors' support and advocacy; the biggest weakness in dealing with all mentors was accessibility. Even when one mentor proved a poor match, another mentor turned out to be an advocate and helpful, thus reaffirming the benefits of a mentoring network as opposed to only a single mentoring relationship. One lesson learned is the importance of preparing mentors for their role via written materials, in-person or phone orientations, and discussions at the annual meeting. Copyright © 2016.

    2000-01-01

    "You're going to teach the organic chemistry section of the Natural Science class?" - one of my biology colleagues asked me last semester - "Better you than me!" "You are?" added a chemistry professor, with interest. Yet these same people ardently believe that all our students should have a basic understanding of carbon's remarkable bonding capabilities and how they relate to life on Earth. If our art or economics majors can learn about organic chemistry and genetics and astronomy, our faculty should be able to teach those same topics, regardless of their acknowledged specialties. The basis of a scientifically literate society is not expertise in specific arcane subfields of science. Scientific literacy is a general understanding of what science is, what science can and cannot do, and what scientific accomplishments have occurred over the centuries. If you subscribe to this definition of scientific literacy, James Trefil and Robert M. Hazen's The Sciences: An Integrated Approach can help you and your general science students. The self-avowed purpose of this text is to address science illiteracy in America. Trefil and Hazen propose that the best way to combat scientific illiteracy is to provide integrated science courses that focus on a broad understanding of science, rather than the specialized knowledge available to a science major. The new edition of The Sciences has been influenced by the 1996 publication of the National Research Council's National Science Education Standards. While the first edition of Trefil and Hazen's book admirably addressed the integration of the natural and physical sciences, in this second edition, the authors have increased the connections between science and real-world situations and have made a more conscious effort to emphasize the process of science and the overlapping nature of scientific disciplines. The text is based on 25 "scientific concepts", one per chapter. These concepts are clearly explained in relatively jargon

Les contributrices ont été en particulier invitées à explorer la relation entre leur identité féministe et leurs croyances religieuses. Le ton de ces contributions varie fortement, allant de l’envie passionnée de concilier les objectifs du féminisme avec le christianisme à un rejet total de l’Eglise comme institution patriarcale suprême.

    2016-02-01

    Full Text Available The influence of process metaphysics on the development of abstraction between 1800 and the second half of the 20th century can best be exemplified with the case of the American Expressionist painter and theoretician Robert Motherwell (1915–1991. Taking as its starting point Motherwell's exposure to the History of Idea of Romanticism, Arthur O. Lovejoy's yearlong seminar at Harvard (1937–38, the artist's affinity with fluid forms through motion brushstrokes in Romanticist painting is analyzed as a preformative stage of his own transitory creations. This is done by structural comparison between Motherwell's written reflections and Romanticist art theory. Motherwell's specific perception through Bergson's and Whitehead's lens of immanence and multiplicity, I argue, resonates Lovejoy's principle of “Romantic Evolutionism,” in its turn from being to becoming, derived from the philosophies of the Spiritualist Maine de Biran and the Idealist–Empiricist George Berkeley.

    Full Text Available This article is dedicated to the understanding of what is read the Bible as literature. We present two moments in the recent history of Bible reading that seem crucial to the definition of this form of reading. The two moments were the publications of two important works that approached the biblical texts from a literary perspective, differing from traditional approaches, religious and exegetical, and influencing the next generations. The first of these two works was Mimesis: The Representation of Reality in Western Literature by Erich Auerbach, originally published in 1946, the other was The Art of Biblical Narrative by Robert Alter, original 1981. We examine some of the main contributions of these two authors for the Bible studies and try to demonstrate that there is a thematic dependence between their works, then list the main assumptions of this way of reading the Bible today, and defend the hypothesis that religious mediation still dividing the Bible studies.

    Full Text Available Already fifty years ago, Frank Robert Tangherlini, an American theoretical physicist, suggested an original procedure which, targeting the synchronization of clocks located in two different inertial reference frames of the space, was di erent from that Einstein had introduced. As a result of these, Tangherlini had deduced the so-called the Tangher- lini transformations, which are a sort of the transformations of the spatial coordinates and time being moved from one inertial reference frame into another one. The Tangher- lini transformations differ from the Lorentz transformations (which can be meant clas- sic ones in the theory of relativity and, in particular, suggest the velocity of light to be anisotropic in a moving inertial reference frame. The Tangherlini transformations be- ing applied provide adequate explanations to all well-known interference experiments checking of the Special Theory of Relativity.

    1992-01-01

    Fifty years ago there were two widely circulated nursing journals, each with a unique purpose and style. The Trained Nurse and Hospital Review was the privately owned older journal, and the American Journal of Nursing was the voice of the professional organization. Each journal was edited by a strong nursing leader, Janet Geister and Mary Roberts, respectively. Each editor had many years of service to the nursing profession in varied capacities. Naturally, each had distinctly different interests, visions, and styles of communication. These editors witnessed and commented on the change in the sphere of nursing practice from a private duty and public health orientation to one that eventually became dominated by the hospital. Although their approaches differed, both recognized the need for organization, versatility, and creative problem solving. However, the legacy of these leaders must be considered in view of the gap that continues to exist between practicing nurses and the American Nurses' Association leadership.

    2016-12-01

    Full Text Available In the US context Fluxus is understood as an advance of the ‘60s radicalism. The assumption that Fluxus was opposed to consumption culture, as that embodied by Pop art, is among the interpretations that renew such a view. Examining the example of Implosions Inc., a short-lived but nevertheless interesting commercial enterprise formed by Robert Watts, Herman Fine and George Maciunas in 1967, this essay focuses its attention on the complex relationship between Fluxus and commercial culture. Implosions Inc. was a project in which many Pop artists were asked to participate along with its Fluxus founders, and it was intended as another step forward in the transformation of the artist into a commodity mass-producer. In analyzing this phenomenon, this article questions assumed principles in the Neo-avantgarde theory like the distinction between art production and culture consumption. The essay, however, will try to establish another paradigm that draws the differences between Pop art and Fluxus as the kind of audiences both these tendencies tried to conform. As a conclusion, the article fleshes out some ideas on individualism that were developed by Maciunas, which shed light on the notions surrounding the idea of collectivism as developed in Fluxus.En el contexto de los EE.UU., Fluxus ha sido entendido como avanzadilla del radicalismo de la década de los 60. La asunción de que Fluxus se oponía a la cultura comercial, tal y como era representada por el pop art, es una de las líneas que renueva dicha interpretación. Mediante el análisis de Implosions Inc., una pequeña pero fundamental empresa de Fluxus que formaron en 1967 George Maciunas, Robert Watts y Herman Fine, este ensayo pretende mostrar colaboraciones entre los artistas Fluxus y Pop y que se propuso hacer del artista un productor de mercancía de masas.

    Sorgner, Helene

    2016-06-01

    This paper compares Feyerabend's arguments in Science in a Free Society to the controversial theory of expertise proposed by Harry Collins and Robert Evans as a Third Wave of Science Studies. Is the legitimacy of democratic decisions threatened by the unquestioned authority of scientific advice? Or does, on the contrary, science need protection from too much democratic participation in technical decisions? Where Feyerabend's political relativism envisions democratic society as inherently pluralist and demands equal contribution of all traditions and worldviews to public decision-making, Collins and Evans hold a conception of elective modernism, defending the reality and value of technical expertise and arguing that science deserves a privileged status in modern democracies, because scientific values are also democratic values. I will argue that Feyerabend's political relativism provides a valuable framework for the evaluation of Collins' and Evans' theory of expertise. By constructing a dialog between Feyerabend and this more recent approach in Science and Technology Studies, the aim of this article is not only to show where the two positions differ and in what way they might be reconciled, but also how Feyerabend's philosophy provides substantial input to contemporary debate.

    Neuroblastoma is often widespread at the time of diagnosis. Three physicians between 1900 and 1910 played an important role in the pathologic definition of neuroblastoma and its route of spread in relation to the age of the patient. These findings eventually led to the advances in treatment and decreased morbidity of today. In 1910 James Homer Wright was the first to recognize the tumor as being of primitive neural cell origin, calling it neuroblastoma and emphasizing the bundle of cells termed rosettes. While Wright recognized the neural nature of the tumor, the authors of previous reports had described its two distinct patterns of spread. In 1901 William Pepper published a series of infants with massive hepatic infiltration associated with adrenal tumors without spread to bone, and in 1907 Robert Grieve Hutchison reported his experience with a similar pathologic process in older infants and children who had orbital and skull metastases. Wright's valuable unifying concept served to tie together the descriptions of Pepper and Hutchison. A century later the names of these physicians should be remembered - Wright, who defined the adrenal tumor as of primitive neural origin, Pepper for his clinically accurate report of massive liver involvement in the infant, and Hutchison for describing the propensity of the tumor to spread to bone in older children.

    The Breakthrough Listen Initiative is undertaking a comprehensive search for radio and optical signatures from extraterrestrial civilizations. An integral component of the project is the design and implementation of wide-bandwidth data recorder and signal processing systems. The capabilities of these systems, particularly at radio frequencies, directly determine survey speed; further, given a fixed observing time and spectral coverage, they determine sensitivity as well. Here, we detail the Breakthrough Listen wide-bandwidth data recording system deployed at the 100 m aperture Robert C. Byrd Green Bank Telescope. The system digitizes up to 6 GHz of bandwidth at 8 bits for both polarizations, storing the resultant 24 GB s‑1 of data to disk. This system is among the highest data rate baseband recording systems in use in radio astronomy. A future system expansion will double recording capacity, to achieve a total Nyquist bandwidth of 12 GHz in two polarizations. In this paper, we present details of the system architecture, along with salient configuration and disk-write optimizations used to achieve high-throughput data capture on commodity compute servers and consumer-class hard disk drives.

    Dr. Robert J. White (1926-2010) was an eminent neurosurgeon and bioethicist, renowned for his classic work in hypothermia and pioneering mammalian head transplant experiments. He founded the Division of Neurosurgery at the Cleveland Metropolitan General Hospital (currently MetroHealth Medical Center, a level 1 trauma county hospital) and became the youngest full professor at the Case Western Reserve University in Cleveland, Ohio. With over 500 research articles to his credit, he founded the Brain Research Laboratory at what was then the Cleveland Metropolitan General Hospital, which was also home to future leaders in neurosurgery, neurosciences, and allied specialties. He transferred a healthy monkey head onto a surgically beheaded monkey body under deep hypothermic conditions drawing both laurels and criticisms alike. Despite a largely controversial neurosurgical research career, his original contributions to deep hypothermia have found profound clinical applications in modern trauma and vascular neurosurgery. The new fusogens and myelorrhaphy methods being tried in Europe hold promise for a future of reanastomosing 2 homologous or heterologous tracts in the neuraxis. Copyright © 2018 Elsevier Inc.

    Roberts syndrome (RBS) (OMIM #268300) is a rare autosomal recessive disorder characterized by tetraphocomelia (symmetrical limb reduction), craniofacial anomalies, growth retardation, mental retardation, cardiac and renal abnormalities. The syndrome is caused by mutations in the ESCO2 (establishment of cohesion 1 homolog 2) (Entrez 609353) gene, which is located at 8p21.1, and encodes a protein essential in establishing sister chromatid cohesion during S phase. SC phocomelia (SC) (OMIM #269000), has less severe symmetric limb reduction, flexion contractures of various joints, minor facial anomalies, growth retardation and occasionally, mental retardation. These two syndromes can be considered part of a spectrum, with RBS at the most severe range in which severely affected infants may be stillborn or die in the post-natal period, while individuals with SC phocomelia represent the milder end of the spectrum and typically survive to adulthood. In both presentations, karyotype investigations characteristically reveal premature centromere separation (PCS), otherwise known as heterochromatin repulsion or puffing. There is little literature about the follow-up of adults with the spectrum of RBS/SC phocomelia or their recommended management. We report on an adult presentation of RBS/SC phocomelia spectrum disorder with a history of major cardiac malformation in childhood, normal limbs on physical examination, mild facial anomalies, mild learning difficulties, and PCS. Molecular studies of ESCO2 have confirmed the diagnosis. A literature review, focussing on adult manifestations of this condition and a discussion of follow-up guidelines are presented.

    Professor Frantisek Por MD and Professor Robert Klopstock MD were contemporaries, both born in 1899, one in Zvolen, the other in Dombovar, at the time of Austro-Hungarian Monarchy. Prof. Por attended the Faculty of Medicine in Budapest from 1918 to 1920, and Prof. Klopstock studied at the same place between 1917 and 1919. From 1920 until graduation on 6th February 1926, Prof. Por continued his studies at the German Faculty of Medicine, Charles University in Prague. Prof. Klopstock had to interrupt his studies in Budapest due to pulmonary tuberculosis; he received treatment at Tatranske Matliare where he befriended Franz Kafka. Later, upon Kafka's encouragement, he changed institutions and continued his studies at the German Faculty of Medicine, Charles University in Prague, where he graduated the first great go. It is very likely that, during their studies in Budapest and Prague, both professors met repeatedly, even though their life paths later separated. Following his graduation, Prof. Por practiced as an internist in Prague, later in Slovakia, and from 1945 in Kosice. In 1961, he was awarded the title of university professor of internal medicine at the Faculty of Medicine, Pavol Jozef Safarik University in Kosice, where he practiced until his death in 1980. Prof. Klopstock continued his studies in Kiel and Berlin. After his graduation in 1933, he practiced in Berlin as a surgeon and in 1938 left for USA. In 1962, he was awarded the title of university professor of pulmonary surgery in NewYork, where he died in 1972.

    It has been suggested that Robert Louis Stevenson's masterpiece Strange Case of Dr. Jekyll and Mr. Hyde derived inspiration from the real-life tragedy of the final days of Connecticut dentist Horace Wells, innovator of the clinical use of the anesthetic properties of nitrous oxide. We examined Stevenson's letters, biographies, and other references in the literature, press, and online to determine whether any factual basis exists for Stevenson to be aware of Wells' life, and also if it played any role in creating the novel's plot. Stevenson was born in Scotland, several years after Wells had committed suicide in New York. Wells' life and death received widespread coverage in the northeastern United States, but there is no evidence that it was printed in newspapers or periodicals in England or Scotland. On the other hand, novelists of the period, psychologists, and the lay public were quite interested in the concept of split personalities and the dual nature of man, so these may have been natural substrates for the novel. There is evidence that Stevenson dreamt about episodes similar to those depicted in his novel. All claims to any relationship between Wells and the novel come from the United States, and none of them are backed by evidence. In the absence of evidence supporting a relationship between the behavior exhibited by Wells during his final days and any inspiration that Stevenson might have derived from it, we conclude that there is insufficient evidence to suggest any relationship between them.

    During a parasitological survey of the ichthyofauna of Lake Catemaco, a freshwater system in the Mexican State of Veracruz, the widespread copepod Ergasilus arthrosis Roberts, 1969 was recovered from two cichlid teleosts, Mayaheros urophthalmus (Günther) and Oreochromis sp. This is the first confirmed record of this copepod species outside of the United States and from Mexico; its finding as a parasite of cichlids represents an expansion of the known host range for this copepod. The local prevalence and intensity of infection of E. arthrosis was highest in M. urophthalmus. The infection prevalence of E. arthrosis on M. urophthalmus (60%) was higher than that known for other ergasilids on cichlids. Ergasilus arthrosis can be distinguished from its closest congener E. lizae Krøyer, 1863 by the morphometry of the antennary segments, the ventral ornamentation of the thoracic sclerites and by details of the antennulary setation, but also by its habitat and host preferences. Taxonomic illustrations and morphological details of the specimens examined are also provided together with comments on the variability of this species.

  12. Variations in dysfunction of sister chromatid cohesion in esco2 mutant zebrafish reflect the phenotypic diversity of Roberts syndrome

    Full Text Available Mutations in ESCO2, one of two establishment of cohesion factors necessary for proper sister chromatid cohesion (SCC, cause a spectrum of developmental defects in the autosomal-recessive disorder Roberts syndrome (RBS, warranting in vivo analysis of the consequence of cohesion dysfunction. Through a genetic screen in zebrafish targeting embryonic-lethal mutants that have increased genomic instability, we have identified an esco2 mutant zebrafish. Utilizing the natural transparency of zebrafish embryos, we have developed a novel technique to observe chromosome dynamics within a single cell during mitosis in a live vertebrate embryo. Within esco2 mutant embryos, we observed premature chromatid separation, a unique chromosome scattering, prolonged mitotic delay, and genomic instability in the form of anaphase bridges and micronuclei formation. Cytogenetic studies indicated complete chromatid separation and high levels of aneuploidy within mutant embryos. Amongst aneuploid spreads, we predominantly observed decreases in chromosome number, suggesting that either cells with micronuclei or micronuclei themselves are eliminated. We also demonstrated that the genomic instability leads to p53-dependent neural tube apoptosis. Surprisingly, although many cells required Esco2 to establish cohesion, 10-20% of cells had only weakened cohesion in the absence of Esco2, suggesting that compensatory cohesion mechanisms exist in these cells that undergo a normal mitotic division. These studies provide a unique in vivo vertebrate view of the mitotic defects and consequences of cohesion establishment loss, and they provide a compensation-based model to explain the RBS phenotypes.

    The Raman spectra of two historical specimens of human hair attributed to the engineer Robert Stephenson and scientist Sir Isaac Newton, preserved in private collections are reported. Comparisons are made with the Raman spectra of modern hair specimens and with hair from archaeological excavations. The hair spectra collected with a laser excitation of 785 nm are of a better quality than those collected using 1064 nm. The historical hair specimens are remarkably well-defined spectroscopically in terms of the amide I vibrational mode and the [small nu](SS), ascribed to a predominantly gauche-gauche-gauche CSSC conformation. The contrast with degraded hair specimens recovered from archaeological excavations is striking. The presence of a weak feature near 2590 cm(-1) in the hair samples attributed to a [small nu](SH) vibration could be indicative of a reduction process operative on the CSSC cystine keratotic linkages and a possible origin of this is bacterial biodegradation identified histologically. This study demonstrates the molecular information available from non-destructive Raman spectroscopic analysis from single hair shafts or small bundles of fibres which complements information available from histological and destructive analytical techniques for rare biological specimens subjected to conservation or curation procedures in museums or private collections.

    Species with relatively narrow niches, such as plants restricted (endemic) to particular soils, may be especially vulnerable to extinction under a changing climate due to the enhanced difficulty they face in migrating to suitable new sites. To test for community-level effects of climate change, and to compare such effects in a highly endemic-rich flora on unproductive serpentine soils vs. the flora of normal (diorite) soils, in 2007 we resampled as closely as possible 108 sites originally studied by ecologist Robert H. Whittaker from 1949 to 1951 in the Siskiyou Mountains of southern Oregon, USA. We found sharp declines in herb cover and richness on both serpentine and diorite soils. Declines were strongest in species of northern biogeographic affinity, species endemic to the region (in serpentine communities only), and species endemic to serpentine soils. Consistent with climatic warming, herb communities have shifted from 1949-1951 to 2007 to more closely resemble communities found on xeric (warm, dry) south-facing slopes. The changes found in the Siskiyou herb flora suggest that biotas rich in narrowly distributed endemics may be particularly susceptible to the effects of a warming climate.

    Cambridge scientists Robert McCance and Elsie Widdowson are best known for their work on the British food tables and wartime food rations, but it is their research on prenatal and early postnatal growth that is today seen as a foundation of the fields studying the impact of environment upon prenatal development and, consequently, adult disease. In this essay I situate McCance's and Widdowson's 1940s human and 1950s experimental studies in the context of pre-war concerns with fetal growth and development, especially within biochemistry, physiology and agriculture; and the Second World War and post-war focus on the effects of undernutrition during pregnancy upon the fetus. I relate Widdowson's and McCance's research on the long-term effects of early undernutrition to the concern with recovery from early trauma so pertinent in post-war Europe and with sensitive (critical) periods, a concept of high importance across different fields. Finally I discuss how, following a hiatus in which fetal physiology engaged with different questions and stressed fetal autonomy, interest in the impact of environment upon prenatal growth and development revived towards the end of the twentieth century. The new field of "developmental origins of health and disease", I suggest, has provided a context in which Widdowson's and McCance's work has regained importance. Copyright © 2013 Elsevier Ltd.

    We studied female graduates of the Robert Wood Johnson Clinical Scholars Program (CSP, Class of 1984 to 1989) to explore and describe the complexity of creating balance in the life of mid-career academic woman physicians. We conducted and qualitatively analyzed (kappa 0.35 to 1.0 for theme identification among rater pairs) data from a semi-structured survey of 21 women and obtained their curricula vitae to quantify publications and grant support, measures of academic productivity. Sixteen of 21 (76%) women completed the survey. Mean age was 48 (range: 45 to 56). Three were full professors, 10 were associate professors, and 3 had left academic medicine. Eleven women had had children (mean 2.4; range: 1 to 3) and 3 worked part-time. From these data, the conceptual model expands on 3 key themes: (1) defining, navigating, and negotiating success, (2) making life work, and (3) making work work. The women who described themselves as satisfied with their careers (10/16) had clarity of values and goals and a sense of control over their time. Those less satisfied with their careers (6/16) emphasized the personal and professional costs of the struggle to balance their lives and described explicit institutional barriers to fulfillment of their potential. For this group of fellowship-prepared academic women physicians satisfaction is achieving professional and personal balance.

    Hematology, serum chemistry, and prevalence of antibodies against selected, pathogens in a San Joaquin kit fox population (Vulpes velox macrotis) were investigated at Camp Roberts Army National Guard Training Site, California, in 1989 and 1990. Samples from 18 (10 female, 8 male) adult kit foxes were used to establish normal hematology and serum chemistry values for this population. Average values were all within the normal ranges reported for kit foxes in other locations. Three hematology parameters had significant differences between male and female values; males had higher total white blood cell and neutrophil counts, and lower lymphocyte counts. There were no significant differences between serum chemistry values from male and female foxes. Prevalence of antibodies was determined from serum samples from 47 (26 female, 21 male) adult kit foxes and eight (4 female, 4 male) juveniles. Antibodies were detected against five of the eight pathogens tested: canine parvovirus, Toxoplasma gondii Leptospira interrogans, canine distemper virus, and canine hepatitis virus. Antibodies were not detected against Brucella, canis, Coccidioides immitis, or Yersinia pestis.

    Full Text Available Tras una breve contextualización de la relevancia de la figura de Robert Malthus en los debates actuales acerca de la población mundial, se examina su pensamiento desde una doble vertiente. En la primera se argumenta que dicho pensamiento ha sido objeto de reducciones al ser clasificado de acuerdo con los criterios actuales de división académica del trabajo, en especial cuando es vinculado a la demografía; Malthus era un economista político y su interés por la demografía estuvo subordinado a sus objetivos investigadores como tal. En la segunda parte del trabajo se incide en las conexiones metodológicas existentes en el trabajo de Malthus y el de un autor tan opuesto a él, pero también economista político, como Karl Marx. Estas conexiones, que separan a ambos de la corriente neoclásica y del pensamiento llamado neomaltusiano, pueden ser relevantes de cara al análisis de problemáticas actuales.

    We define a measure of network cohesion and show how it arises naturally in a broad class of dynamic models of endogenous perpetual growth with network externalities. Via a standard growth model, we show why network cohesion is crucial for conditional convergence and explain that as cohesion increases, convergence is faster. We prove properties of network cohesion and define a network aggregator that preserves network cohesion.

    Full Text Available La publication récente par le Borneo Research Council d’un ouvrage collectif sur la mort fournit l’occasion de réévaluer l’apport de Robert Hertz à la compréhension des rites funéraires à Bornéo. Si la traduction en anglais, dans les années 1960, de l’essai de Hertz sur la représentation collective de la mort avait consacré, grâce notamment aux travaux de Peter Metcalf sur les Berawan, la puissance du modèle analytique hertzien, ce nouvel ouvrage semble signaler que le moment de la célébration finale est venu, où les héritiers se libèrent de l’emprise spirituelle du défunt. Tout en conservant une grande part de sa valeur comme théorie du deuil, le paradigme transitionnel ou « réactif » de Hertz révèle ses limites, mises ici en lumière par des données ethnographiques encore peu connues ou inédites, qui démontrent, par exemple, l’existence d’une circulation des composantes de la personne par delà l’opposition entre la vie et la mort, ou encore l’influence directe des secondes funérailles sur la renaissance des défunts. Cet article aborde le dépassement du modèle hertzien en retournant à la lettre de l’essai, dont il met en relief l’intelligence ethnographique et la finesse théorique.The recent publication by the Borneo Research Council of a collection of essays on death provides an opportunity to reassess the heritage of Robert Hertz, whose theory of the double obsequies relies heavily on the ethnography of the Ngaju and other Borneo peoples. The translation of Hertz’s essay on the collective representation of death in the 1960s, prompting in particular Peter Metcalf’s work on the Berawan, has consecrated the explanatory power of Hertz’s model. With this new book, however, time seems to have come for the final celebration that marks the heirs’ liberation from the deceased’s spiritual influence.

The article points to resources held in archives in Ireland and the United States that can additionally address questions related to this film. While a noteworthy contribution to the filmography of Robert Flaherty, the short ‘talkie’ must be approached with caution by folklorists due to the coaching of actors and cinematographic editing.

    Prediction and control of the dynamics of complex networks is a central problem in network science. Structural and dynamical similarities of different real networks suggest that some universal laws might accurately describe the dynamics of these networks, albeit the nature and common origin of such laws remain elusive. Here we show that the causal network representing the large-scale structure of spacetime in our accelerating universe is a power-law graph with strong clustering, similar to many complex networks such as the Internet, social, or biological networks. We prove that this structural similarity is a consequence of the asymptotic equivalence between the large-scale growth dynamics of complex networks and causal networks. This equivalence suggests that unexpectedly similar laws govern the dynamics of complex networks and spacetime in the universe, with implications to network science and cosmology.

    2012-06-01

    Dr Robert R. Shaw arrived in Dallas to practice Thoracic Surgery in 1937, as John Alexander's 7th Thoracic Surgical Resident from Michigan University Medical Center. Dr Shaw's modus operandi was, "You can accomplish almost anything, if you don't care who gets the credit." He was a remarkable individual who cared the most about the patient and very little about getting credit for himself. From 1937 to 1970, Dr Shaw established one of the largest lung cancer surgical centers in the world in Dallas, Texas. It was larger than M.D. Anderson and Memorial Sloan-Kettering Hospitals put together regarding the surgical treatment of lung cancer patients. To accomplish this, he had the help of Dr Donald L. Paulson, who trained at the Mayo Clinic and served as Chief of Thoracic Surgery at Brook Army Hospital during the Second World War. Following the War, because of his love for Texas, he ended up as a partner of Dr Shaw in Dallas. Together, they pursued the development of this very large surgical lung cancer center. Dr Shaw and his wife Ruth went to Afghanistan with Medico multiple times to teach men modern cardiac and thoracic surgery. They also served as consultants on Medico's Ship of Hope in Africa. Dr Shaw initiated multiple new operations including: 1) resection of Pancoast's cancer of the lung after preoperative irradiation; 2) upper lobe of the lung bronchoplasty, reattaching (and saving) the lower lobe to prevent the "disabling" pneumonectomy; and 3) resections of pulmonary mucoid impaction of the lung in asthmatics. Because of his humility and giving "the credit to others," Dr Shaw was never President of a major medical or surgical association. Copyright © 2012 The Society of Thoracic Surgeons.

    The investigation into whether Mars contains signatures of past or present life is of great interest to science and society. Amino acids and nucleobases are compounds that are essential for all known life on Earth and are excellent target molecules in the search for potential Martian biomarkers or prebiotic chemistry. Martian meteorites represent the only samples from Mars that can be studied directly in the laboratory on Earth. Here, we analyzed the amino acid and nucleobase content of the shergottite Roberts Massif (RBT) 04262 using liquid chromatography-mass spectrometry. We did not detect any nucleobases above our detection limit in formic acid extracts; however, we did measure a suite of protein and nonprotein amino acids in hot-water extracts with high relative abundances of beta-alanine and gamma-amino-eta-butyric acid. The presence of only low (to absent) levels of several proteinogenic amino acids and a lack of nucleobases suggest that this meteorite fragment is fairly uncontaminated with respect to these common biological compounds. The distribution of straight-chained amine-terminal eta-omega-amino acids in RBT 04262 resembled those previously measured in thermally altered carbonaceous meteorites. A carbon isotope ratio of -24(0/00) +/- 6(0/00) for beta-alanine in RBT 04262 is in the range of reduced organic carbon previously measured in Martian meteorites (Steele et al. 2012). The presence of eta-omega-amino acids may be due to a high temperature Fischer-Tropschtype synthesis during igneous processing on Mars or impact ejection of the meteorites from Mars, but more experimental data are needed to support these hypotheses.

  5. Temporal networks

    CERN Document Server

    Saramäki, Jari

    2013-01-01

    The concept of temporal networks is an extension of complex networks as a modeling framework to include information on when interactions between nodes happen. Many studies of the last decade examine how the static network structure affect dynamic systems on the network. In this traditional approach  the temporal aspects are pre-encoded in the dynamic system model. Temporal-network methods, on the other hand, lift the temporal information from the level of system dynamics to the mathematical representation of the contact network itself. This framework becomes particularly useful for cases where there is a lot of structure and heterogeneity both in the timings of interaction events and the network topology. The advantage compared to common static network approaches is the ability to design more accurate models in order to explain and predict large-scale dynamic phenomena (such as, e.g., epidemic outbreaks and other spreading phenomena). On the other hand, temporal network methods are mathematically and concept...

  6. Interconnected networks

    CERN Document Server

    2016-01-01

    This volume provides an introduction to and overview of the emerging field of interconnected networks which include multi layer or multiplex networks, as well as networks of networks. Such networks present structural and dynamical features quite different from those observed in isolated networks. The presence of links between different networks or layers of a network typically alters the way such interconnected networks behave – understanding the role of interconnecting links is therefore a crucial step towards a more accurate description of real-world systems. While examples of such dissimilar properties are becoming more abundant – for example regarding diffusion, robustness and competition – the root of such differences remains to be elucidated. Each chapter in this topical collection is self-contained and can be read on its own, thus making it also suitable as reference for experienced researchers wishing to focus on a particular topic.

  9. Network Ambivalence

    Directory of Open Access Journals (Sweden)

    Patrick Jagoda

    2015-08-01

    Full Text Available The language of networks now describes everything from the Internet to the economy to terrorist organizations. In distinction to a common view of networks as a universal, originary, or necessary form that promises to explain everything from neural structures to online traffic, this essay emphasizes the contingency of the network imaginary. Network form, in its role as our current cultural dominant, makes scarcely imaginable the possibility of an alternative or an outside uninflected by networks. If so many things and relationships are figured as networks, however, then what is not a network? If a network points towards particular logics and qualities of relation in our historical present, what others might we envision in the future? In  many ways, these questions are unanswerable from within the contemporary moment. Instead of seeking an avant-garde approach (to move beyond networks or opting out of networks (in some cases, to recover elements of pre-networked existence, this essay proposes a third orientation: one of ambivalence that operates as a mode of extreme presence. I propose the concept of "network aesthetics," which can be tracked across artistic media and cultural forms, as a model, style, and pedagogy for approaching interconnection in the twenty-first century. The following essay is excerpted from Network Ambivalence (Forthcoming from University of Chicago Press. 

  10. A tribute to Dr. Robert C. Allen, an inspirational teacher, humanitarian, and friend (Nov. 18, 1950-Mar. 24, 2005).

    Science.gov (United States)

    Edlich, Richard F; Greene, Jill A; Long, William B

    2006-01-01

    Dr. Robert C. Allen was a gifted educator, as well as experienced ophthalmologist, who was a close personal friend of Dr. Edlich at the University of Virginia Health System. While serving on the faculty at the University of Virginia Health System, Dr. Allen proved to be a compassionate physician, who developed close personal relationships with the residents, faculty, and his patients. Dr. Allen was invited by Dr Edlich to be a member of the Editorial Board of the Journal of Long-Term Effects of Medical Implants. When Dr. Allen told Dr. Edlich that he had ocular melanoma in 2000, this news was a wake-up call to Dr. Edlich on the need to prevent skin cancer, as well as ocular melanoma. Empowered by this news, Dr. Edlich was honored to co-author four articles on skin cancer prevention, as well as the latest article focusing on prevention of ocular melanoma. The Ocular Melanoma Foundation (Richmond, VA (USA)) was founded in 2003 by Dr. Robert C. Allen to increase awareness, enhance education, and provide advocacy among both patients and health care professionals regarding this rare, but potentially lethal cancer. It has a website that provides patient information, up-to-date information and enables communication/ discourse between and among patients and practitioners (admin@ocularmelanoma.org). Dr. Allen died on March 24, 2005, at his home surrounded by family and loved ones. When surgeons are faced with challenging healthcare diseases, Dr. Edlich's mentor, Dr. Owen Wangensteen, advised Dr. Edlich that he should seek the advice and guidance of skilled basic scientists, who are familiar with the problem. Dr. Wangensteen is recognized as the greatest surgical teacher during the 20th century. Consequently, Dr. Edlich enlisted the advice and guidance from the two co-authors of the next article regarding the scientific basis for the selection of sunglasses to prevent the development of cataracts, pterygia, skin cancer, as well as ocular melanoma.

    2012-01-01

    This study sets out to extend and challenge existing historiography on late eighteenth century British popular culture, customary sports, class and cultural identity, focusing upon the rural geo-political borderland of England. It suggests that prevailing class-based and more London-biased studies need to be balanced with more regionalist-based work, and shows the importance of northern regional leisure variants. The textual and historical analysis draws largely on the published works of a neglected working-class dialect poet, Robert Anderson, living and working in Cumberland, arguing that he represented a strain of ''bardic regionalism,'' a variant of Katie Trumpener’s ''bardic nationalism.''

  3. Spatial networks

    Science.gov (United States)

    Barthélemy, Marc

    2011-02-01

    Complex systems are very often organized under the form of networks where nodes and edges are embedded in space. Transportation and mobility networks, Internet, mobile phone networks, power grids, social and contact networks, and neural networks, are all examples where space is relevant and where topology alone does not contain all the information. Characterizing and understanding the structure and the evolution of spatial networks is thus crucial for many different fields, ranging from urbanism to epidemiology. An important consequence of space on networks is that there is a cost associated with the length of edges which in turn has dramatic effects on the topological structure of these networks. We will thoroughly explain the current state of our understanding of how the spatial constraints affect the structure and properties of these networks. We will review the most recent empirical observations and the most important models of spatial networks. We will also discuss various processes which take place on these spatial networks, such as phase transitions, random walks, synchronization, navigation, resilience, and disease spread.

    Our dependence on networks - be they infrastructure, economic, social or others - leaves us prone to crises caused by the vulnerabilities of these networks. There is a great need to develop new methods to protect infrastructure networks and prevent cascade of failures (especially in cases of coupled networks). Terrorist attacks on transportation networks have traumatized modern societies. With a single blast, it has become possible to paralyze airline traffic, electric power supply, ground transportation or Internet communication. How, and at which cost can one restructure the network such that it will become more robust against malicious attacks? The gradual increase in attacks on the networks society depends on - Internet, mobile phone, transportation, air travel, banking, etc. - emphasize the need to develop new strategies to protect and defend these crucial networks of communication and infrastructure networks. One example is the threat of liquid explosives a few years ago, which completely shut down air travel for days, and has created extreme changes in regulations. Such threats and dangers warrant the need for new tools and strategies to defend critical infrastructure. In this paper we review recent advances in the theoretical understanding of the vulnerabilities of interdependent networks with and without spatial embedding, attack strategies and their affect on such networks of networks as well as recently developed strategies to optimize and repair failures caused by such attacks.

  7. Chromatid repulsion associated with Roberts/SC phocomelia syndrome is reduced in malignant cells and not expressed in interspecies somatic-cell hybrids.

    Science.gov (United States)

    Krassikoff, N E; Cowan, J M; Parry, D M; Francke, U

    1986-01-01

    Different cell types from a female patient with Roberts/SC phocomelia syndrome were evaluated quantitatively for the presence of repulsion of heterochromatin and satellite regions of mitotic chromosomes. Whereas EBV-transformed lymphoblasts from an established cell line revealed these phenomena at frequencies equal to those in PHA-stimulated lymphocytes and cultured skin fibroblasts, aneuploid cells from a metastatic melanoma displayed them at 50% lower frequency. Cocultivation of the patient's fibroblasts with either an immortal Chinese hamster cell line or with a human male fibroblast strain carrying a t(4;6)(p14;q21) translocation showed that the phenomenon was not corrected or induced by a diffusible factor or by cell-to-cell contact. In each experiment, only the patient's metaphase spreads revealed chromatid repulsion. In fusion hybrids between the patient's fibroblasts and an established Chinese hamster cell line, the human chromosomes behaved perfectly normally, suggesting that the gene product which is missing or mutant in Roberts/SC phocomelia syndrome is supplied by the Chinese hamster genome.

    2016-10-29

    McRoberts' and suprapubic pressure are often recommended as the initial choices of manoeuvres to manage shoulder dystocia, as they are believed to be less invasive compared to other manoeuvres. However, their success rates range from 23 to 40 %. This study aims to investigate the predictive factors for the success of McRoberts' manoeuvre with or without suprapubic pressure (M+/-S). All cases of shoulder dystocia in a tertiary hospital in South East Asia were recruited from 1995 to 2009. Subjects were analysed according to either 'success' or 'failure' of M+/-S. Maternal and fetal antenatal and intrapartum factors were compared by univariate and multivariate analysis. Among 198 cases of shoulder dystocia, M+/-S as the primary manoeuvre was successful in 25.8 %. The other 74.2 % needed either rotational or posterior arm manoeuvres or combination of manoeuvres. Instrumental delivery was the single most significant factor associated with an increased risk of failed M+/-S on logistic regression (p dystocia occurred after instrumental delivery but was 47.7 % after spontaneous vaginal delivery. When shoulder dystocia occurs after instrumental vaginal delivery, the chance of failure of M+/-S is 85 %, which is 4.7 times higher than that after spontaneous vaginal delivery. Hence all operators performing instrumental delivery should be proficient in performing all manoeuvres to relieve shoulder dystocia when M+/-S cannot do so.

Boyd Blackwell, Anthony Cooper, Chris Hegna, Stuart Hudson, John Krommes, Alexander Pletzer, Ellen Zweibel, and I gave talks that covered various aspects of Bob's wide-ranging scholarship, and his leadership in the Australian and the US fusion program. At the Symposium, Bob gave an insightful talk, published in this issue as a paper with D Leykam. This paper makes available for the first time unpublished results from Bob's M Sc Thesis on a general method for calculating the potential around a `dressed' test particle in an isotropic and collisionless plasma. The paper is interesting not only because it provides a glimpse of the type of elegant applied mathematics that we have come to associate with Bob, but also because he discusses some leitmotifs in his intellectual evolution since the time he was a graduate student at the University of Melbourne and Princeton University. Through his early encounter with quantum field theory, Bob appreciated the power of Lagrangian and Hamiltonian formalisms, which he used with great effectiveness in nonlinear dynamics and plasma physics. A question that animates much of his work is one that underlies the `dressed' particle problem: if one is given a Hamiltonian with an unperturbed (or `bare') part and an interaction part, how is one to obtain a canonical transformation to `the oscillation centre' thatwould reduce the interaction part to an irreducible residual part while incorporating the rest in a renormalized zeroth-order Hamiltonian? One summer in Princeton, I worked with Bob on a possible variational formulation for this problem, and failed. I was daunted enough by my failure that I turned

    of CoPs we shall argue that the metaphor or theory of networked learning is itself confronted with some central tensions and challenges that need to be addressed. We then explore these theoretical and analytic challenges to the network metaphor, through an analysis of a Danish social networking site. We......In this article we take up a critique of the concept of Communities of Practice (CoP) voiced by several authors, who suggest that networks may provide a better metaphor to understand social forms of organisation and learning.

    This book introduces the security mechanisms deployed in Ethernet, Wireless-Fidelity (Wi-Fi), Internet Protocol (IP) and MultiProtocol Label Switching (MPLS) networks. These mechanisms are grouped throughout the book according to the following four functions: data protection, access control, network isolation, and data monitoring. Data protection is supplied by data confidentiality and integrity control services. Access control is provided by a third-party authentication service. Network isolation is supplied by the Virtual Private Network (VPN) service. Data monitoring consists of applying

    This is the final version of the article. It first appeared from Springer via http://dx.doi.org/10.1007/s00199-016-0992-1 We define a measure of network cohesion and show how it arises naturally in a broad class of dynamic models of endogenous perpetual growth with network externalities. Via a standard growth model, we show why network cohesion is crucial for conditional convergence and explain that as cohesion increases, convergence is faster. We prove properties of network cohesion and d...

    2007-01-01

    In order to optimize the management of the Technical Network (TN), to ease the understanding and purpose of devices connected to the TN, and to improve security incident handling, the Technical Network Administrators and the CNIC WG have asked IT/CS to verify the "description" and "tag" fields of devices connected to the TN. Therefore, persons responsible for systems connected to the TN will receive email notifications from IT/CS asking them to add the corresponding information in the network database. Thank you very much for your cooperation. The Technical Network Administrators & the CNIC WG

    With their ability to solve problems in massive information distribution and processing, while keeping scaling costs low, overlay systems represent a rapidly growing area of R&D with important implications for the evolution of Internet architecture. Inspired by the author's articles on content based routing, Overlay Networks: Toward Information Networking provides a complete introduction to overlay networks. Examining what they are and what kind of structures they require, the text covers the key structures, protocols, and algorithms used in overlay networks. It reviews the current state of th

    Bipartite networks refer to a specific kind of network in which the nodes (or actors) can be partitioned into two subsets based on the fact that no links exist between actors within each subset, but only between the two subsets. Due to the partition of actors in two sets and the absence of relations

    A great variety of systems in nature, society and technology-from the web of sexual contacts to the Internet, from the nervous system to power grids-can be modeled as graphs of vertices coupled by edges. The network structure, describing how the graph is wired, helps us understand, predict and optimize the behavior of dynamical systems. In many cases, however, the edges are not continuously active. As an example, in networks of communication via e-mail, text messages, or phone calls, edges represent sequences of instantaneous or practically instantaneous contacts. In some cases, edges are active for non-negligible periods of time: e.g., the proximity patterns of inpatients at hospitals can be represented by a graph where an edge between two individuals is on throughout the time they are at the same ward. Like network topology, the temporal structure of edge activations can affect dynamics of systems interacting through the network, from disease contagion on the network of patients to information diffusion over an e-mail network. In this review, we present the emergent field of temporal networks, and discuss methods for analyzing topological and temporal structure and models for elucidating their relation to the behavior of dynamical systems. In the light of traditional network theory, one can see this framework as moving the information of when things happen from the dynamical system on the network, to the network itself. Since fundamental properties, such as the transitivity of edges, do not necessarily hold in temporal networks, many of these methods need to be quite different from those for static networks. The study of temporal networks is very interdisciplinary in nature. Reflecting this, even the object of study has many names-temporal graphs, evolving graphs, time-varying graphs, time-aggregated graphs, time-stamped graphs, dynamic networks, dynamic graphs, dynamical graphs, and so on. This review covers different fields where temporal graphs are considered
