description: Until recently little was known about the high-dimensional operators of the standard model effective field theory (SMEFT). However, in the past few years the number of these operators has been counted up to mass dimension 15 using techniques involving the Hilbert series. In this work I will show how to perform the same counting with a different method. This alternative approach makes it possible to cross-check results (it confirms the SMEFT numbers), but it also provides some more information on the operators beyond just counting their number. The considerations made here apply equally well to any other model besides SMEFT and, with this purpose in mind, they were implemented in a computer code.

description: This paper describes the cutting sequences of geodesic flow on the modular surface H/PSL(2,Z) with respect to the standard fundamental domain F = {z=x+iy: -1/2 <= x <= 1/2 and |z|>=1} of PSL(2,Z). The cutting sequence for a vertical geodesic {θ+it: t > 0} is related to a one-dimensional continued fraction expansion for θ, called the one-dimensional Minkowski geodesic continued fraction (MGCF) expansion, which is associated to a parametrized family of reduced bases of a family of 2-dimensional lattices. The set of cutting sequences for all geodesics forms a two-sided shift in a symbol space {L,R,J} which has the same set of forbidden blocks as for vertical geodesics. We show that this shift is not a sofic shift, and that it characterizes the fundamental domain F up to an isometry of the hyperbolic plane H. We give conversion methods between the cutting sequence for the vertical geodesic {θ+it: t > 0}, the MGCF expansion of θand the additive ordinary continued fraction (ACF) expansion of θ. We show that the cutting sequence and MGCF expansions can each be computed from the other by a finite automaton, and the ACF expansion of θcan be computed from the cutting sequence for the vertical geodesic θ+it by a finite automaton. However, the cutting sequence for a vertical geodesic cannot be computed from the ACF expansion by any finite automaton, but there is an algorithm to compute its first l symbols when given as input the first O(l) symbols of the ACF expansion, which takes time O(l^2) and space O(l).

description: In this paper we will present recent work on a new unit-level small area methodology that can be used with continuous and discrete outcomes. The proposed method is based on constructing a model-based estimator of the distribution function by using a nested-error regression model for the quantiles of the target outcome. A general set of domain-specific parameters that extends beyond averages is then estimated by sampling from the estimated distribution function. For fitting the model we exploit the link between the Asymmetric Laplace Distribution and maximum likelihood estimation for quantile regression. The specification of the distribution of the random effects is considered in some detail by exploring the use of parametric and non- parametric alternatives. The use of the proposed methodology with discrete (count) outcomes requires appropriate transformations, in particular jittering. For the case of discrete outcomes the methodology relaxes the restrictive assumptions of the Poisson generalised linear mixed model and allows for what is potentially a more flexible mean-variance relationship. Mean Squared Error estimation is discussed. Extensive model-based simulations are used for comparing the proposed methodology to alternative unit-level methodologies for estimating a broad range of complex parameters.

description: A $k$-cycle with a pendant edge attached to each vertex is called a $k$-sun. The existence problem for $k$-sun decompositions of $K_v$, with $k$ odd, has been solved only when $k=3$ or $5$. By adapting a method used by Hoffmann, Lindner and Rodger to reduce the spectrum problem for odd cycle systems of the complete graph, we show that if there is a $k$-sun system of $K_v$ ($k$ odd) whenever $v$ lies in the range $2k< v < 6k$ and satisfies the obvious necessary conditions, then such a system exists for every admissible $v\geq 6k$.

description: We derive boundary conditions for the covariant open string corresponding to D-branes in an Hpp-wave, by requiring kappa symmetry of its bulk action. Both half-supersymmetric and quarter-supersymmetric branes are seen to arise in this way, and the analysis furthermore agrees fully with the existing probe brane and supergravity computations. We elaborate on the origin of dynamical and kinematical supersymmetries from the covariant point of view. In particular we focus on the D-string which only preserves half of the dynamical supersymmetries and none of the kinematical ones. We discuss its origin in AdS_5 x S^5 and its world-volume spectrum.

description: Acetaminophen is among the most commonly used nonopioid analgesics, but significant variation exists in its prescribing practices for cirrhosis patients. Our primary objective was to describe the quality of evidence supporting or refuting the use of acetaminophen in patients with hepatic dysfunction. A comprehensive literature review of PubMed, Cochrane Library, Web of Science, and International Pharmaceutical Abstracts using the search terms “acetaminophen,” “paracetamol,” “chronic liver disease,” “cirrhosis,” and “hepatic disease” for studies describing changes in acetaminophen metabolism in patients with hepatic dysfunction was conducted. Twelve studies and four abstracts were included. Ten studies and three abstracts were pharmacokinetic studies. Two studies and one abstract evaluated the association of acetaminophen use and decompensation in the cirrhotic patient. The level of certainty for dosing recommendations obtainable from reviewing the evidence is low due to a small number of studies meeting search criteria, small samples sizes, inadequate information regarding cirrhosis etiology and compensated versus uncompensated liver disease, and lack of information on patient centered health outcomes. High-quality trials are not available to support the use of decreased acetaminophen doses in compensated cirrhosis patients. Acetaminophen can be a safe analgesic in patients with compensated hepatic dysfunction after careful analysis of patient-specific factors.

Topology comparison of Twitter diffusion networks effectively reveals misleading information

description: In recent years, malicious information had an explosive growth in social media, with serious social and political backlashes. Recent important studies, featuring large-scale analyses, have produced deeper knowledge about this phenomenon, showing that misleading information spreads faster, deeper and more broadly than factual information on social media, where echo chambers, algorithmic and human biases play an important role in diffusion networks. Following these directions, we explore the possibility of classifying news articles circulating on social media based exclusively on a topological analysis of their diffusion networks. To this aim we collected a large dataset of diffusion networks on Twitter pertaining to news articles published on two distinct classes of sources, namely outlets that convey mainstream, reliable and objective information and those that fabricate and disseminate various kinds of misleading articles, including false news intended to harm, satire intended to make people laugh, click-bait news that may be entirely factual or rumors that are unproven. We carried out an extensive comparison of these networks using several alignment-free approaches including basic network properties, centrality measures distributions, and network distances. We accordingly evaluated to what extent these techniques allow to discriminate between the networks associated to the aforementioned news domains. Our results highlight that the communities of users spreading mainstream news, compared to those sharing misleading news, tend to shape diffusion networks with subtle yet systematic differences which might be effectively employed to identify misleading and harmful information.

Comparing Simulations and Observations of Galaxy Evolution: Methods for Constraining the Nature of Stellar Feedback

description: Computational hydrodynamical simulations are a very useful tool for understanding how galaxies form and evolve over cosmological timescales not easily revealed through observations. However, they are only useful if they reproduce the sorts of galaxies that we see in the real universe. One of the ways in which simulations of this sort tend to fail is in the prescription of stellar feedback, the process by which nascent stars return material and energy to their immediate environments. Careful treatment of this interaction in subgrid models, so-called because they operate on scales below the resolution of the simulation, is crucial for the development of realistic galaxy models. Equally important is developing effective methods for comparing simulation data against observations to ensure galaxy models which mimic reality and inform us about natural phenomena. This thesis examines the formation and evolution of galaxies and the observable characteristics of the resulting systems. We employ extensive use of cosmological hydrodynamical simulations in order to simulate and interpret the evolution of massive spiral galaxies like our own Milky Way. First, we create a method for producing synthetic photometric images of grid-based hydrodynamical models for use in a direct comparison against observations in a variety of filter bands. We apply this method to a simulation of a cluster of galaxies to investigate the nature of the red-sequence/blue-cloud dichotomy in the galaxy color-magnitude diagram. Second, we implement several subgrid models governing the complex behavior of gas and stars on small scales in our galaxy models. Several numerical simulations are conducted with similar initial conditions, where we systematically vary the subgrid models, afterward assessing their efficacy through comparisons of their internal kinematics with observed systems. Third, we generate an additional method to compare observations with simulations, focusing on the tenuous circumgalactic medium. Informed by our previous studies, we investigate the sensitivity of this new mode of comparison to hydrodynamical subgrid prescription. Finally, we synthesize the results of these studies and identify future avenues of research.

We denote this field broadly as nanoscale magnetophotonics. We include a general introduction to the field and describe the emerging magneto-optical effects in magnetoplasmonic and magnetophotonic nanostructures supporting localized and propagating plasmons. Special attention is given to magnetoplasmonic crystals with transverse magnetization and the associated nanophotonic non-reciprocal effects, and to magneto-optical effects in periodic arrays of nanostructures. We give also an overview of the applications of these systems in biological and chemical sensing, as well as in light polarization and phase control. We further review the area of nonlinear magnetophotonics, the semiconductor spin-plasmonics, and the general principles and applications of opto-magnetism and nano-optical ultrafast control of magnetism and spintronics.

description: In economic development, there are often regions that share similar economic characteristics, and economic models on such regions tend to have similar covariate effects. In this paper, we propose a Bayesian clustered regression for spatially dependent data in order to detect clusters in the covariate effects. Our proposed method is based on the Dirichlet process which provides a probabilistic framework for simultaneous inference of the number of clusters and the clustering configurations. The usage of our method is illustrated both in simulation studies and an application to a housing cost dataset of Georgia.

What is the least order finite group, $G_g$, for which there is a homomorphism $ψ$ from $π_1(F_g)$ to $G_g$ so that no nontrivial simple closed curve on $F_g$ represents an element in Ker($ψ$)? For the torus it is easily seen that $G_1 = Z_2 \times Z_2$ suffices. We prove here that $G_2$ is a group of order 32 and that an upper bound for the order of $G_g$ is given by $g^{2g +1}$. The previously known upper bound was greater than $2^{g{2^{2g}}}$.

description: Molecular switches on metal surfaces typically show very little photoreactivity. Using scanning tunneling microscopy, we show that the ring- opening–ring-closing switch nitrospiropyran thermally and optically isomerizes to the open merocyanine form on a Bi(110) surface. Irradiation by blue light of a monolayer of spiropyran molecules leads to mixed domains of the two isomers. At large illumination intensities a photostationary state is established, indicating the bidirectional ring-opening and ring-closing reaction of these molecules on the bismuth surface. The enhanced photoactivity contrasts with the case of adsorption on other metal surfaces, probably due to the low density of states at the Fermi level of the semimetallic Bi(110) surface.

description: In this paper we present an investigation about techniques and frameworks supporting in situ-visualization. With this term we mean that visualization is coupled with simulation and it occurs whilst the simulation is running. By coupling these together we can utilize the high performance computing for post processing, and we can circumvent the bottlenecks associated with storing and retrieving data in disk storage. Moreover it allows monitoring the simulation in-situ, performing not only visualization, but analysis of the incoming data as it is generated so that the simulation may be stopped or modified, thereby conserving CPU resources. In particular we have tested two techniques, by exploiting different visualization tools on two applications. The first one is the astrophysics code Pluto instrumented by using a ParaView plug-in called ICARUS, the second one is the neural simulator code BrainCore instrumented by using a library of VisIt.

description: Ribonucleotide reductases (RNRs) are essential for DNA synthesis in most organisms. In class-Ic RNR from Chlamydia trachomatis (Ct), a MnFe cofactor in subunit R2 forms the site required for enzyme activity, instead of an FeFe cofactor plus a redox-active tyrosine in class-Ia RNRs, for example in mouse (Mus musculus, Mm). For R2 proteins from Ct and Mm, either grown in the presence of, or reconstituted with Mn and Fe ions, structural and electronic properties of higher valence MnFe and FeFe sites were determined by X-ray absorption spectroscopy and complementary techniques, in combination with bond-valence-sum and density functional theory calculations. At least ten different cofactor species could be tentatively distinguished. In Ct R2, two different Mn(IV)Fe(III) site configurations were assigned either L4MnIV(μO)2FeIIIL4 (metal–metal distance of ~ 2.75 Å, L = ligand) prevailing in metal-grown R2, or L4MnIV(μO)(μOH)FeIIIL4 (~ 2.90 Å) dominating in metal- reconstituted R2. Specific spectroscopic features were attributed to an Fe(IV)Fe(III) site (~ 2.55 Å) with a L4FeIV(μO)2FeIIIL3 core structure. Several Mn,Fe(III)Fe(III) (~ 2.9–3.1 Å) and Mn,Fe(III)Fe(II) species (~ 3.3–3.4 Å) likely showed 5-coordinated Mn(III) or Fe(III). Rapid X-ray photoreduction of iron and shorter metal–metal distances in the high-valent states suggested radiation-induced modifications in most crystal structures of R2. The actual configuration of the MnFe and FeFe cofactors seems to depend on assembly sequences, bound metal type, valence state, and previous catalytic activity involving subunit R1. In Ct R2, the protonation of a bridging oxide in the MnIV(μO)(μOH)FeIII core may be important for preventing premature site reduction and initiation of the radical chemistry in R1.

description: The Hans-Ertel Centre for Weather Research is a network of German universities, research institutes and the German Weather Service (Deutscher Wetterdienst, DWD). It has been established to trigger and intensify basic research and education on weather forecasting and climate monitoring. The performed research ranges from nowcasting and short-term weather forecasting to convective-scale data assimilation, the development of parameterizations for numerical weather prediction models, climate monitoring and the communication and use of forecast information. Scientific findings from the network contribute to better understanding of the life-cycle of shallow and deep convection, representation of uncertainty in ensemble systems, effects of unresolved variability, regional climate variability, perception of forecasts and vulnerability of society. Concrete developments within the research network include dual observation-microphysics composites, satellite forward operators, tools to estimate observation impact, cloud and precipitation system tracking algorithms, large-eddy-simulations, a regional reanalysis and a probabilistic forecast test product. Within three years, the network has triggered a number of activities that include the training and education of young scientists besides the centre's core objective of complementing DWD's internal research with relevant basic research at universities and research institutes. The long term goal is to develop a self-sustaining research network that continues the close collaboration with DWD and the national and international research community.

description: We discuss an application of the method of the angular quantization to reconstruction of form-factors of local fields in massive integrable models. The general formalism is illustrated with examples of the Klein-Gordon, sinh-Gordon and Bullough-Dodd models. For the latter two models the angular quantization approach makes it possible to obtain free field representations for form-factors of exponential operators. We discuss an intriguing relation between the free field representations and deformations of the Virasoro algebra. The deformation associated with the Bullough-Dodd models appears to be different from the known deformed Virasoro algebra.

description: Our concern is the axiomatisation problem for modal and algebraic logics that correspond to various fragments of two-variable first-order logic with counting quantifiers. In particular, we consider modal products with Diff, the propositional unimodal logic of the difference operator. We show that the two-dimensional product logic Diff x Diff is non-finitely axiomatisable, but can be axiomatised by infinitely many Sahlqvist axioms. We also show that its `square' version (the modal counterpart of the substitution and equality free fragment of two-variable first-order logic with counting to two) is non-finitely axiomatisable over Diff x Diff, but can be axiomatised by adding infinitely many Sahlqvist axioms. These are the first examples of products of finitely axiomatisable modal logics that are not finitely axiomatisable, but axiomatisable by explicit infinite sets of canonical axioms.
title: More than Words: An Examination of Intimate Expression in Men’s Homosocial Friendships
Creators: name: Walters, Benjamin James
Publisher: name: Griffith University
Year: 2016
Subjects: subject: Homosexual platonic friendships
subject: Homosexual intimacy
subject: Homosexual friendship

description: Despite a history of high quality research in the area, division exists within literature examining gender and communication regarding the degree to which men experience platonic intimacy in their homosocial friendships. Dominant theoretical approaches range from those suggesting that communication behaviours typical of men’s friendships are unemotive and, therefore, lacking in intimacy (e.g., Gupta et al., 2013; Levy, 2005; Reisman, 1990); to those suggesting that men’s friendships feature overt emotional intimacy, such as vulnerable disclosure (e.g., Batalha, Reynolds, & Newbigin, 2011; Hyde, 2005; Walker, 1994). The present research aimed to examine the various modes of expressing intimacy men employed within a friendship context (Study 1), the degree to which this expression met men’s needs for intimacy (Studies 1 and 3), and the impact of contextual factors and individual subscription to masculine role norms on men’s use of various modes of expression (Study 2). A mixed methods design was employed to assess intimacy in accordance with men’s subjective definitions. Importantly, studies were designed with the limiting implicit assumptions of some previous research in mind (such as the assumption that covert expression is inherently less intimate than vulnerable expression; and that masculinity is inherently incongruent with vulnerable expression). In doing this, the present research attempted to gain new perspective on hitherto unresolved issues in this area of research.

Fictitious gauge fields in bilayer graphene

description: We discuss the effect of elastic deformations on the electronic properties of bilayer graphene membranes. Distortions of the lattice translate into fictitious gauge fields in the electronic Dirac Hamiltonian that are explicitly derived here for arbitrary elastic deformations, including in-plane as well as flexural (out-of-plane) distortions. We include gauge fields associated to intra- as well as interlayer hopping terms and discuss their effects on the electronic band structure and on the transport properties of suspended bilayer membranes. In particular, we consider the electron-phonon coupling induced by the fictitious gauge fields and analyze its contribution to the electrical resistivity. Of special interest is the appearance of a linear coupling for flexural modes, in stark contrast to the case of monolayer graphene. This new coupling channel is shown to dominate the temperature- dependent resistivity in suspended samples with low tension.
Comparing and Contrasting Korean and Japanese Government Responses to Sex Trafficking

description: The purpose of this paper is to compare and contrast modern South Korean and Japanese government responses to the issue of sex trafficking. By comparing and contrasting both government responses, I aim to gain a greater understanding as to why the government responses in both countries have differed despite similar causes of trafficking and to look at the implications of the remedies enforced by the governments to combat sex trafficking. This paper will specifically examine factors such as law and policy, economic interests, NGOs, and law enforcement. By examining these factors, this paper will argue that the South Korean and Japanese government responses are heavily influenced by the prioritization of economic interest over human rights.

description: The objective of this study was to evaluate the quality and comparability of published literature, and to summarize the effect of prostaglandin F(2α) (PGF(2α)) for the treatment of endometritis. It has been postulated that there is a dearth of high-level evidence-based research results in veterinary medicine. Also, there is a marked variation in the quality of studies in veterinary and animal science. Post-partum uterine infections occur commonly in dairy cattle and are reported to have a negative impact on reproductive performance. A comprehensive literature search was conducted utilizing online databases revealing a total of 2723 references. After applying specific exclusion criteria, a total of 68 trials were eligible for further analysis. These articles were evaluated utilizing specific parameters listed in an evaluation form such as randomization and the involvement of control groups. The analysis revealed that more than half of the trials (51·5%) were at least 20 years old. Furthermore, we found that about one third (36·8%) of all trials were controlled and randomized, while 3 of those (4·4%) were also blinded. Of those trials which calculated a calving-to-conception interval (n=30), 50% of the authors claimed an improvement, which was statistically significant in 23·3% of the cases. We conclude that there is a wide discrepancy between research results investigating the efficacy of PGF(2α).

description: Diverse and inclusive environments in work and professional settings are difficult to find, and more difficult to create. Tech companies, academic departments, conferences, governing bodies, all are increasingly hunting for better practices to reduce bias. This statement relates my record and contributions to diversity, and my vision for continuing to make a lasting difference in the communities and institutions I belong to.

Inequalities in our society are structural, permeating through various dimensions of our endeavors. Being active to curb inequalities thus involves many efforts: some through formal programs, others through spontaneous and informal interactions with individuals in our circles. In my role as an academic and educator, I have taken the opportunity to advance diversity through both systematic activities, and eclectic minor actions—this statement reflects that mix.

Vector operators in the BMN correspondence

Year: 2002
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We consider a BMN operator with one scalar, phi, and one vector, D_{m}Z, impurity field and compute the anomalous dimension both at planar and torus levels. This "mixed" operator corresponds to a string state with two creation operators which belong to different SO(4) sectors of the background. The anomalous dimension at both levels is found to be the same as the scalar impurity BMN operator. At planar level this constitutes a consistency check of BMN conjecture. Agreement at the torus level can be explained by an argument using supersymmetry and supression in the BMN limit. The same argument implies that a class of fermionic BMN operators also have the same planar and torus level anomalous dimensions. Implications of the results for the map from N=4 SYM theory to string theory in the pp-wave background are discussed.
