description: Despite the recent rapid progress in numerical relativity, a convergence order less than the second has so far plagued codes solving the Einstein-Euler system of equations. We report simulations of the inspiral of binary neutron stars in quasi-circular orbits computed with a new code employing high-order, high-resolution shock-capturing, finite-differencing schemes that, for the first time, go beyond the second-order barrier. In particular, without any tuning or alignment, we measure a convergence order above three both in the phase and in the amplitude of the gravitational waves. Because the new code is able to calculate waveforms with very small phase errors already at modest resolutions, we are able to obtain accurate estimates of tidal effects in the inspiral that are essentially free from the large numerical viscosity typical of lower-order methods, and even for the challenging large compactness and small-deformability binary considered here. We find a remarkable agreement between our Richardson-extrapolated waveform and the one from the tidally corrected post-Newtonian (PN) Taylor-T4 model, with a de-phasing smaller than 0.2 radians during the seven orbits of the inspiral and up to the contact point. Because our results can be used reliably to assess the validity of the PN or other approximations at frequencies significantly larger than those considered so far in the literature, they seem to exclude at these compactnesses significant tidal amplifications from next-to-next-to-leading--order terms in the PN expansion.

COMMENTS: Placed in Xenogale by Allen (1919b), and followed by Rosevear (1974) and Ansell (1978). This taxon, and ichneumon, which is generally recognized as its sister taxon (Allen, 1919b; Rosevear, 1974; Hayman, in Sanderson, 1940), can be distinguished principally by proportional differences of the interorbital region (Rosevear, 1974). Hayman (in Sanderson, 1940), Wenzel and Haltenorth (1972), and Coetzee (1977b) did not feel these differences were sufficient to warrant generic distinction, as did Allen (1919b), and Rosevear (1974). Recognition of Xenogale would make Herpestes paraphyletic.

description: We solve a long-standing puzzle in Statistical Mechanics of disordered systems. By performing a high-statistics simulation of the D=3 random-field Ising model at zero temperature for different shapes of the random-field distribution, we show that the model is ruled by a single universality class. We compute the complete set of critical exponents for this class, including the correction-to-scaling exponent, and we show, to high numerical accuracy, that scaling is described by two independent exponents. Discrepancies with previous works are explained in terms of strong scaling corrections.

description: We demonstrate, by considering the triangular lattice spin-1/2 Heisenberg model, that Monte Carlo sampling of skeleton Feynman diagrams within the fermionization framework offers a universal first-principles tool for strongly correlated lattice quantum systems. We observe the fermionic sign blessing---cancellation of higher order diagrams leading to a finite convergence radius of the series. We calculate the magnetic susceptibility of the triangular-lattice quantum antiferromagnet in the correlated paramagnet regime and reveal a surprisingly accurate microscopic correspondence with its classical counterpart at all accessible temperatures. The extrapolation of the observed relation to zero temperature suggests the absence of the magnetic order in the ground state. We critically examine the implications of this unusual scenario.

description: Ile68Leu transthyretin-related amyloidosis (ATTR) is known as a mainly or exclusively cardiogenic variant. We hypothesized that an accurate specialized neurological evaluation could reveal a consistent frequency of mixed phenotypes. Forty-six consecutive subjects with transthyretin (TTR) Ile68Leu (p.Ile88Leu) mutation (29 patients and 17 unaffected carriers) underwent an in-depth cardiac and neurologic evaluation at a single center. All 29 patients showed cardiac involvement. In 20 (69%) cases, it was associated with neurological abnormalities (i.e. a mixed phenotype): 10 (35% of the total) had signs and symptoms of neuropathy, 5 (17%) had abnormalities at the neurologic specialist examination but without symptoms, and 5 (17%) had abnormal nerve conduction study only. None of the asymptomatic carriers showed neurological abnormalities or cardiac involvement. The Neuropathy Impairment Score was > 5 in seven patients at baseline, and became >5 in six more patients during follow-up. The probability of experiencing a major adverse cardiac event (MACE) during follow-up was higher in the mixed than cardiologic phenotype (p = 0.026). Age and phenotype were independent prognostic predictors of MACE. At least two-thirds of patients with Ile68Leu ATTR and amyloidotic cardiomyopathy show an associated – definite or probable – neurologic impairment of variable degree if accurately evaluated in a neurologic setting. This proportion can rise during follow-up. The mixed phenotype carries a worse prognosis compared to the exclusively cardiologic one. These observations show that more patients could be eligible for treatment with gene silencers than currently indicated and highlight the need for an in-depth and continuous multidisciplinary evaluation of Ile68Leu ATTR patients.
Continental glaciation in the Glenlyon area, Pelly River District, Yukon, Canada

description: The Glenlyon area in central Yukon is bounded by 62°
and 63°N and 134° and 136°W. It is part of the Yukon Plateau, a mature upland surface surmounted by isolated peaks and small ranges, and dissected by deep, young valleys. Features of glacial erosion and deposition ore such that the direction of flow and the upper limit or the last glaciation can be determined from them.

Ice flowed into central Yukon from three sources, Selwyn
Mountains to the east, Cassiar mountains to the southeast,
and the Coast and St. Elias mountains to the south. Ice
moved into the Glenlyon area from the first two of these
sources and apparently the maximum stages of these two gla
cial advances were not synchronous, but Selwyn ice was active last. In this area, many higher mountains and hills projected above the ice surface as nunataks. In detail, topography altered the direction of ice flow, ice thickness and extent.

Evidence from adjacent parts of Yukon suggest two or possibly three glaciations but only the last has been recognized in the Glenlyon area although this could not have escaped glaciation in earlier stages. The large glaciers of central Yukon developed by windward building in contrast with the Cordilleren ice sheet in central British Columbia which developed on the lee of the Coast Range.

description: We re-examine previous observations of folding kinetics of compressed lipid monolayers in light of the accepted mechanical buckling mechanism recently proposed [L. Pocivavsek et al., Soft Matter, 2008, 4, 2019]. Using simple models, we set conservative limits on a) the energy released in the mechanical buckling process and b) the kinetic energy entailed by the observed folding motion. These limits imply a kinetic energy at least thirty times greater than the energy supplied by the buckling instability. We discuss possible extensions of the accepted picture that might resolve this discrepancy.

The electrostatic interaction of an external charged system with a metal surface: a simplified density functional theory approach

description: As a first step to meet the challenge to calculate the electronic structure and total energy of charged states of atoms and molecules adsorbed on ultrathin-insulating films supported by a metallic substrate using density functional theory (DFT), we have developed a simplified new DFT scheme that only describes the electrostatic interaction of an external charged system with a metal surface. This purely electrostatic interaction is obtained from the assumption that the electron densities of the two fragments (charged system and metal surface) are non-overlapping and neglecting non-local exchange correlation effects such as the van der Waals interactions between the two fragments. In addition, the response of the metal surface to the electrostatic potential from the charged system is treated to linear order, whereas the charged system is treated fully within DFT. In particular, we consider the classical perfect conductor (PC) model for the metal response, although our formalism is not limited to this approximation. The successful computational implementation of this new methodology and the PC model is exemplified by the case of a Na$^{+}$ cation outside a metal surface.

description: In this paper we present a lattice Boltzmann model for combustion and detonation. In this model the fluid behavior is described by a finite-difference lattice Boltzmann model by Gan et al. [Physica A, 2008, 387: 1721]. The chemical reaction is described by the Lee-Tarver model [Phys. Fluids, 1980, 23: 2362]. The reaction heat is naturally coupled with the flow behavior. Due to the separation of time scales in the chemical and thermodynamic processes, a key technique for a successful simulation is to use the operator-splitting scheme. The new model is verified and validated by well-known benchmark tests. As a specific application of the new model, we studied the simple steady detonation phenomenon. To show the merit of LB model over the traditional ones, we focus on the reaction zone to study the non-equilibrium effects. It is interesting to find that, at the von Neumann peak, the system is nearly in its thermodynamic equilibrium. At the two sides of the von Neumann peak, the system deviates from its equilibrium in opposite directions. In the front of von Neumann peak, due to the strong compression from the reaction product behind the von Neumann peak, the system experiences a sudden deviation from thermodynamic equilibrium. Behind the von Neumann peak, the release of chemical energy results in thermal expansion of the matter within the reaction zone, which drives the system to deviate the thermodynamic equilibrium in the opposite direction. From the deviation from thermodynamic equilibrium, defined in this paper, one can understand more on the macroscopic effects of the system due to the deviation from its thermodynamic equilibrium.

title: Writing characters from under-represented communities: a perspective from an emerging young adult fiction writer
Creators: name: Hehir, Sylvia
Publisher: name: University of Glasgow
Year: 2018
Subjects: subject: Under-represented communities, young adult fiction.

description: The category of young adult (YA) fiction encompasses a wide range of genres; but despite this generic diversity, it has so far failed to represent the full range of communities that make up contemporary British society. Discussions are ongoing between professionals in the publishing industry and campaigning individuals and organisations who are aiming to redress this imbalance. Writers making new work are in a position to help effect a change, but acknowledging and responding to the call for inclusion can be far from straightforward, with questions being raised such as: ‘how far can a writer stray from their own lived experience?’ and ‘how can a writer avoid tokenism or cultural appropriation when writing for inclusion?’ This thesis consists of a new YA contemporary novel, Sea Change, and an accompanying critical essay, which reflects on the challenges I encountered while aiming to write for inclusion. Set in the Scottish Highlands, Sea Change is a contemporary YA crime novel, in which the world of the sixteen-year-old protagonist, Alex, is thrown into turmoil when he discovers a dead body next to his fishing boat. The decisions Alex makes following this discovery set in motion the plot of the story. The narrative, as it unfolds, facilitates the exploration of themes frequently associated with adolescence, such as friendship, risk-taking and the maturation into an adult identity, along with themes specifically linked to Alex’s status as a member of marginalised communities because of his sexuality and social class, such as prejudice, acute stress brought on by economic pressure, and low self-esteem. This thesis, then, reviews the opinions and recommendations being expressed by campaigners for greater diversity, and exposes the uncertainties and challenges a writer faces when aiming to write for inclusion.
Information amplification via postselection: A parameter estimation perspective

description: It is known that weak measurement can significantly amplify the mean of measurement results, sometimes out of the range limited in usual quantum measurement. This fact, as actively demonstrated recently in both theory and experiment, implies the possibility to estimate a very small parameter using the weak measurement technique. But does the weak measurement really bring about the increase of "information" for parameter estimation? This paper clarifies that, in a general situation, the answer is NO; more precisely, the weak measurement cannot further decrease the lower bound of the estimation error, i.e. the so-called Cramér-Rao bound, which is proportional to the inverse of the quantum Fisher information.

description: We present a new model of the extragalactic background light (EBL) and corresponding gamma-gamma opacity for intergalactic gamma-ray absorption from z = 0 up to z = 10, based on a semi-analytical model of hierarchical galaxy formation that reproduces key observed properties of galaxies at various redshifts. Including the potential contribution from Population III stars and following the cosmic reionization history in a simplified way, the model is also broadly consistent with available data concerning reionization, particularly the Thomson scattering optical depth constraints from WMAP. In comparison with previous EBL studies up to z ~ 3-5, our predicted gamma-gamma opacity is in general agreement for observed gamma-ray energy below 400/(1 + z) GeV, whereas it is a factor of ~ 2 lower above this energy because of a correspondingly lower cosmic star formation rate, even though the observed UV luminosity is well reproduced by virtue of our improved treatment of dust obscuration and direct estimation of star formation rate. The horizon energy at which the gamma-ray opacity is unity does not evolve strongly beyond z ~ 4 and approaches ~ 20 GeV. The contribution of Population III stars is a minor fraction of the EBL at z = 0, and is also difficult to distinguish through gamma-ray absorption in high-z objects, even at the highest levels allowed by the WMAP constraints. Nevertheless, the attenuation due to Population II stars should be observable in high-z gamma-ray sources by telescopes such as Fermi or CTA and provide a valuable probe of the evolving EBL in the rest-frame UV. The detailed results of our model are publicly available in numerical form at the URL http://www.slac.stanford.edu/~yinoue/Download.html.

description: Data collection is a key component of an information system. The widespread penetration of ICT tools in organizations and institutions has resulted in a shift in the way the data is collected. Data may be collected in printed-form, by e-mails, on a compact disk, or, by direct upload on the management information system. Since web services are platform-independent, it can access data stored in the XML format from any platform. In this paper, we present an interface which uses web services for data collection. It requires interaction between a web service deployed for the purposes of data collection, and the web address where the data is stored. Our interface requires that the web service has pre-knowledge of the address from where the data is to be collected. Also, the data to be accessed must be stored in XML format. Since our interface uses computer-supported interaction on both sides, it eases the task of regular and ongoing data collection. We apply our framework to the Education Management Information System, which collects data from schools spread across the country.

Publisher: name: California Institute of Technology

Subjects: Aeronautics

description: The equations governing a three-layer beam in which the middle layer is viscoelastic were derived by means of a variational principle.  These equations were solved subject to arbitrary time dependent boundary conditions of both the simply-supported and cantilever type.  In the simply-supported case, an eigenfunction expansion was constructed after the governing equations had been transformed through operation by a differential operator.  In the cantilever case, the solution was obtained by Fourier transform with respect to time, and inversion by residue theory.  An analysis of the theoretical response of the cantilever beam to steady state sinusoidal loading was carried out, and an experiment was conducted for comparison.

description: Inflammatory stimuli drive a fine rearrangement of cell-specific chromatin determinants at cis-regulatory regions of inflammatory genes. Although a few determinants are known (i.e. H3K4me1 and Pu.1), a global picture of the enhancers? molecular signature and how specific factors dynamically synergize during the inflammatory response remain incomplete. The aim of my thesis is the global characterization of the enhancers? determinants and their dynamic profiling during inflammatory response. I addressed this issue by employing the chromatin proteomics approach (ChroP), which combines chromatin immunoprecipitation and mass spectrometry-based proteomics, to dissect histone post-translational modifications (modificome) and chromatin-binding proteins (interactome) associated with a specific chromatin region. We used H3K4me1 and Pu.1 antibodies to specifically enrich enhancers from macrophage-derived RAW264.7 cells. Native chromatin and formaldehyde-fixed chromatin from SILAC-labeled cells were used for the hPTMs profiling and the identification of chromatin binding proteins, respectively. Furthermore, a triple-SILAC setup was used in time-course experiments to profile the gene transcriptional activation triggered by lipopolysaccharide. Our findings suggest that enhancers have in basal condition an overall higher-ordered structure that is maintained during the inflammation; while a subset of proteins displays a dynamic behavior, i.e. the PBAF complex and Dnmt1, that seem to synergize with specific hPTMs to set an environment permissive to transcription. Interestingly, a number of factors are newly recruited at enhancers, suggesting a role in fine-tuning the appropriate gene expression: among them, Junb and Stat1 are well characterized to be involved in inflammatory response, while others (i.e. DDIT3 and Ifi204) are novel, very promising and under further investigation.

description: We demonstrate the existence of supersonic bell soliton in the Bardeen-Cooper-Schrieffer-Bose-Einstein condensate (BCS-BEC) crossover regime. Starting from the extended Thomas-Fermi density functional theory of superfluid order parameter, a density transformation is used to map the hydrodynamic mean field equation to a Lienard type equation. As a result, bell solitons are obtained as exact solutions, which is further verified by the numerical solution of the dynamical equation. The stability of the soliton is established and its behaviour in the entire crossover domain is obtained. It is found that, akin to the case of vortices, the bell solitons yield highest contrast in the BEC regime.

description: The performance of the turbojet engine for high component efficiency is approximated by an ideal expression (efficiencies equal unity) plus the first terms of a Taylor Series expansion for the purpose of isolating the individual effects of the components.

The analytical solution to two optimizations is presented; namely:

(A) For fixed burner outlet temperature, flight Mach number, and component efficiency, what is the compressor pressure ratio corresponding to maximum jet velocity (maximum thrust per unit mass flow)?

(B) For fixed flight Mach number, compressor pressure ratio and component efficiency, what is the burner outlet temperature corresponding to minimum specific fuel consumption?
title: Assessing Organizational Effectiveness Through the Competing Values Framework A Data Envelopment Approach

Publisher: name: Old Dominion University Libraries
Year: 2014

description: This study proposes a model to diagnose organizations using the mathematical principles of data envelopment analysis (DEA) to the variables generated using competing values :framework (CVF) in order to evaluate overall organizational effectiveness. The notion of organizational effectiveness is abstract and difficult to measure due to its complexity and multi-functional nature. Over the years, measurement of organizational effectiveness has remained a challenge due to the lack of agreement on the factors that should be assessed to determine effectiveness. This research is aimed at shedding some light into this topic by using data envelopment analysis as a tool to measure relative efficiency based on a predefined effectiveness model. The effectiveness model is prepared on basis of competing values framework.

The relative efficiency scores that are obtained though this integrated approach compare and suggest the best practices that may be employed by an organization. In this research, a measurement model integrating CVF and DEA is developed and tested in context of power and hand tool manufacturers. The results obtained tested the feasibility of the model to assess organizational effectiveness. The findings may provide useful information to company stakeholders and business analysts about the factors that influence critical outcomes and compare that information with that of major competitors.

description: The effect of on-site electron-electron repulsion $U$ in a band insulator is explored for a bilayer Hubbard Hamiltonian with opposite sign hopping in the two sheets. The ground state phase diagram is determined at half-filling in the plane of $U$ and the interplanar hybridization $V$ through a computation of the antiferromagnetic (AF) structure factor, local moments, single particle and spin wave spectra, and spin correlations. Unlike the case of the ionic Hubbard model, no evidence is found for a metallic phase intervening between the Mott and band insulators. Instead, upon increase of $U$ at large $V$, the behavior of the local moments and of single-particle spectra give quantitative evidence of a crossover to a Mott insulator state preceding the onset of magnetic order. Our conclusions generalize those of single-site dynamical mean field theory, and show that including interlayer correlations results in an increase of the single particle gap with $U$.

Feshbach Resonance in a Tight-Binding Model

description: The physics of Feshbach resonance is analyzed using an analytic expression for the $s$-wave scattering phase-shift and the scattering length $a$ which we derive within a two-channel tight-binding model. Employing a unified treatment of bound states and resonances in terms of the Jost function, it is shown that for strong inter-channel coupling, Feshbach resonance can occur even when the closed channel does not have a bound state. This may extend the range of ultra-cold atomic systems that can be manipulated by Feshbach resonance. The dependence of the sign of $a$ on the coupling strength in the unitary limit is elucidated. As a by-product, analytic expressions are derived for the background scattering length, the external magnetic field at which resonance occurs, and the energy shift $\varepsilon-\varepsilon_B$, where $\varepsilon$ is the scattering energy and $\varepsilon_B$ is the bound state energy in the closed channel (when there is one).

description: The modification of the electronic current resulting from Stark resonances has been studied for the semiconductor nanowire with the double-barrier structure. Based on the calculated current-voltage characteristics we have shown that the resonant tunneling current is a periodic function of the width of the spacer layer. We have also demonstrated that the simultaneous change of the source-drain voltage and the voltage applied to the gate located near the nanowire leads to almost periodic changes of the resonant tunneling current as a function of the source-drain and gate voltages. The periodic properties of the resonant tunneling current result from the formation of the Stark resonance states. If we change the electric field acting in the nanowire, the Stark states periodically acquire the energies from the transport window and enhance the tunneling current in a periodic manner. We have found that the separations between the resonant current peaks on the source-drain voltage scale can be described by a slowly increasing linear function of the Stark state quantum number. This allows us to identify the quantum states that are responsible for the enhancement of the resonant tunneling. We have proposed a method of the experimental observation of the Stark resonances in semiconductor double-barrier heterostructures.

description: Given a polynomial f(z) = z^d + c over a global field K and a_0 in K, we study the density of prime ideals of K dividing at least one element of the orbit of a_0 under f. The density of such sets for linear polynomials has attracted much study, and the second author has examined several families of quadratic polynomials, but little is known in the higher-degree case. We show that for many choices of d and c this density is zero for all a_0, assuming K contains a primitive dth root of unity. The proof relies on several new results, including some ensuring the number of irreducible factors of the nth iterate of f remains bounded as n grows, and others on the ramification above certain primes in iterated extensions. Together these allow for nearly complete information when K is a global function field or when K=Q(zeta_d).

description: Artykuł przedstawia wnioski z badań dotyczących społeczności wirtualnych skupionych wokół gier mutliplayer i tego, jak kształtują one relacje społeczne. Autor zaczyna od wprowadzenia czytelnika w nowczesny świat, oparty o pryncypium interaktywności, przedstawiając literaturę dotyczącą zagadanienia, by później przejść do etnograficznego opisu badanej grupy. Tego dokonuje zaś z dwóch perspektyw – jako insidera, członka owej społeczności, oraz badacza, opierając się na jakościowych wywiadach z osobami zaangażowami w forum i grę. Autor konkluduje, iż badaną grupę można opisać jako "społeczność budowniczych" w myśl kategorii Roberta Kozinetsa, a także, że takie społeczności tworzą relacje równie mocne, jak grupy występujące w rzeczywistości. Osoby zaangażowane w społeczności wirtualne tego typu szukają również możliwości do dewirtualizowania kontaktów, które zbudowały w Sieci przez lata swojej obecności w tym kontekście.

description: Five physics mechanisms of interaction leading to the binding of the ${\rm H}_3^+$ molecular ion are identified. They are realized in a form of variational trial functions and their respective total energies are calculated. Each of them provides subsequently the most accurate approximation for the Born-Oppenheimer (BO) ground state energy among (two-three-seven)-parametric trial functions being correspondingly, H$_2$-molecule plus proton (two variational parameters), H$_2^+$-ion plus H-atom (three variational parameters) and generalized Guillemin-Zener (seven variational parameters). These trial functions are chosen following a criterion of physical adequacy. They include the electronic correlation in the exponential form $\sim\exp{(γr_{12})}$, where $γ$ is a variational parameter. Superpositions of two different mechanisms of binding are investigated and a particular one, which is a generalized Guillemin-Zener plus H$_2$-molecule plus proton (ten variational parameters), provides the total energy at the equilibrium of $E=-1.3432$\ a.u. The superposition of three mechanisms: generalized Guillemin-Zener plus (H$_2$ -molecule plus proton) plus (H$_2^+$ -ion plus H) (fourteen parameters) leads to the total energy which deviates from the best known BO energy to $\sim 0.0004$\ a.u., {\it it reproduces two-three significant digits in exact, non-BO total energy}. In general, our variational energy agrees in two-three-four significant digits with the most accurate results available at present as well as major expectation values.

description: We present a new perturbative formulation of non-equilibrium thermal field theory, based upon non-homogeneous free propagators and time-dependent vertices. The resulting time-dependent diagrammatic perturbation series are free of pinch singularities without the need for quasi-particle approximation or effective resummation of finite widths. After arriving at a physically meaningful definition of particle number densities, we derive master time evolution equations for statistical distribution functions, which are valid to all orders in perturbation theory and all orders in a gradient expansion. For a scalar model, we make a loopwise truncation of these evolution equations, whilst still capturing fast transient behaviour, which is found to be dominated by energy-violating processes, leading to non-Markovian evolution of memory effects.
