Electromagnetism in terms of quantum measurements
Creators: name: Andersson, Andreas
Publisher: name: arXiv
Year: 2015
Subjects: subject: Mathematical Physics (math-ph)
subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We consider the question whether electromagnetism can be derived from quantum physics of measurements. It turns out that this is possible, both for quantum and classical electromagnetism, if we use more recent innovations such as smearing of observables and simultaneous measurability. In this way we justify the use of von Neumann-type measurement models for physical processes. We apply operational quantum measurement theory to gain insight in fundamental aspects of quantum physics. Interactions of von Neumann type make the Heisenberg evolution of observables describable using explicit operator deformations. In this way one can obtain quantized electromagnetism as a measurement of a system by another. The relevant deformations (Rieffel deformations) have a mathematically well-defined "classical" limit which is indeed classical electromagnetism for our choice of interaction.

description: By event-driven molecular dynamics simulations we investigate magneto-transport in a two-dimensional model with randomly distributed scatterers close to the field-induced localization transition. This transition is generated by percolating skipping orbits along the edges of obstacle clusters. The dynamic exponents differ significantly from those of the conventional transport problem on percolating systems, thus establishing a new dynamic universality class. This difference is tentatively attributed to a weak-link scenario, which emerges naturally due to barely overlapping edge trajectories. We make predictions for the frequency-dependent conductivity and discuss implications for active colloidal circle swimmers in a heterogeneous environment.

Examining socioeconomic health disparities using a rank-dependent Rényi index
Creators: name: Talih, Makram
Publisher: name: arXiv
Year: 2015
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: The Rényi index (RI) is a one-parameter class of indices that summarize health disparities among population groups by measuring divergence between the distributions of disease burden and population shares of these groups. The rank-dependent RI introduced in this paper is a two-parameter class of health disparity indices that also accounts for the association between socioeconomic rank and health; it may be derived from a rank-dependent social welfare function. Two competing classes are discussed and the rank-dependent RI is shown to be more robust to changes in the distribution of either socioeconomic rank or health. The standard error and sampling distribution of the rank-dependent RI are evaluated using linearization and resampling techniques, and the methodology is illustrated using health survey data from the U.S. National Health and Nutrition Examination Survey and registry data from the U.S. Surveillance, Epidemiology and End Results Program. Such data underlie many population-based objectives within the U.S. Healthy People 2020 initiative. The rank-dependent RI provides a unified mathematical framework for eliciting various societal positions with regards to the policies that are tied to such wide-reaching public health initiatives. For example, if population groups with lower socioeconomic position were ascertained to be more likely to utilize costly public programs, then the parameters of the RI could be selected to reflect prioritizing those population groups for intervention or treatment.

Weak Godel's incompleteness property for some decidable versions of first order logic

description: The founding of the theory of cylindric algebras, by Alfred Tarski, was a conscious effort to create algebras out of first order predicate calculus. Let $n\inω$. The classes of non-commutative cylindric algebras ($NCA_n$) and weakened cylindric algebras ($WCA_n$) were shown, by István Németi, to be examples of decidable versions of first order logic with $n$ variables. In this article, we give new proofs for the decidability of the equational theories of these classes. We also give an answer to the open problem, posed by Németi in 1985, addressing the atomicity of the finitely generated free algebras of these classes. We prove that all the finitely generated free algebras of the varieties $NCA_n$ and $WCA_n$ are not atomic. In other words, we prove that the corresponding versions of first order logic have weak Gödel's incompleteness property.
Racial socialization and identity across the transition to middle school among African American youth
Creators: name: Hudgens, Tanée M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Grade, gender, and reporter differences in parental racial socialization practices and their relationship to race centrality were assessed in 197 African American child-parent pairs when the children were in 5th and 7th grades. Parents reported on their racial socialization practices with their children (racial pride and preparation for discrimination), and children reported their perceptions of their parents' behaviors. Contrary to study hypotheses, racial socialization practices did not increase after children entered middle school. Furthermore, few gender differences emerged, and the predicted bidirectional relationship between parental racial socialization and race centrality was not supported. The interplay among gender, racial socialization, and contextual change in shaping the identity development of African American youth is discussed.
Muon g$-$2 in two-Higgs-doublet models

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: Updating various theoretical and experimental constraints on the four different types of two-Higgs-doublet models (2HDMs), we find that only the ``lepton-specific" (or ``type X") 2HDM can explain the present muon g$-$2 anomaly in the parameter region of large $\tanβ$, a light CP-odd boson, and heavier CP-even and charged bosons which are almost degenerate. The severe constraints on the models come mainly from the consideration of vacuum stability and perturbativity, the electroweak precision data, the $b$-quark observables like $B_S \to μμ$, the precision measurements of the lepton universality as well as the 125 GeV boson property observed at the LHC.

description: We examine a modification of the Kuramoto model for phase oscillators coupled on a network. Here, two populations of oscillators are considered, each with different network topologies, internal and cross-network couplings and frequencies. Additionally, frustration parameters for the interactions of the cross-network phases are introduced. This may be regarded as a model of competing populations: internal to any one network phase synchronisation is a target state, while externally one or both populations seek to frequency synchronise to a phase in relation to the competitor. We conduct fixed point analyses for two regimes: one, where internal phase synchronisation occurs for each population with the potential for instability in the phase of one population in relation to the other; the second where one part of a population remains fixed in phase in relation to the other population, but where instability may occur within the first population leading to `fragmentation'. We compare analytic results to numerical solutions for the system at various critical thresholds.

description: Inspired by the peculiarities of the effective geometry of crystalline structures, we reconsider thick brane scenarios from a metric-affine perspective. We show that for a rather general family of theories of gravity, whose Lagrangian is an arbitrary function of the metric and the Ricci tensor, the background and scalar field equations can be written in first-order form, and tensorial perturbations have a non negative definite spectrum, which makes them stable under linear perturbations regardless of the form of the gravity Lagrangian. We find, in particular, that the tensorial zero modes are exactly the same as predicted by Einstein's theory regardless of the scalar field and gravitational Lagrangians.

To sing is more than to remember: literary and philosophical allusion in the songs of Caetano Veloso
Creators: name: Wilkenfeld, Jacob Nelson
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: This thesis examines the literary associations that, through allusion, Brazilian singer/songwriter Caetano Veloso brings to bear upon his work and suggests interpretations of the meanings sparked by these meetings of different texts. By reading seven allusive lyrics in Veloso's songbook, I intend to show that the songwriter's use of such allusions is a key aspect of his aesthetic and a mark of his broadening of the poetic dimensions of popular song. My aim is not to trace every allusion that Veloso makes, but rather to provide a framework for interpreting what his art of allusion generally entails. Furthermore, I underscore those aspects of Veloso's allusions that reflect the songwriter's dynamic reworking of literary material, rather than tracing the passive assimilation of "influences." That is, I analyze the way in which Veloso both invokes past writers and creates works that underscore their own creative difference from previous texts.
Gap state analysis in electric-field-induced band gap for bilayer graphene

description: The origin of the low current on/off ratio at room temperature in dual-gated bilayer graphene field-effect transistors is considered to be the variable range hopping in gap states. However, the quantitative estimation of gap states has not been conducted. Here, we report the systematic estimation of the energy gap by both quantum capacitance and transport measurements and the density of states for gap states by the conductance method. An energy gap of ~250 meV is obtained at the maximum displacement field of ~3.1 V/nm, where the current on/off ratio of ~3*10^3 is demonstrated at 20 K. The density of states for the gap states are in the range from the latter half of 10^12 to 10^13 eV^-1cm^-2. Although the large amount of gap states at the interface of high-k oxide/bilayer graphene limits the current on/off ratio at present, our results suggest that the reduction of gap states below ~10^11 eV^-1cm^-2 by continual improvement of the gate stack makes bilayer graphene a promising candidate for future nanoelectronic device applications.

description: Both gamma-ray bursts (GRBs) and blazars have relativistic jets pointing at a small angle from our line of sight. Several recent studies suggested that these two kinds of sources may share similar jet physics. In this work, we explore the variability properties for GRBs and blazars as a whole. We find that the correlation between minimum variability timescale (MTS) and Lorentz factor, $Γ$, as found only in GRBs by Sonbas et al. can be extended to blazars with a joint correlation of $\rm MTS\proptoΓ^{-4.7\pm0.3}$. The same applies to the $\rm MTS\propto \it L_γ^{\rm -1.0\pm0.1}$ correlation as found in GRBs, which can be well extended into blazars as well. These results provide further evidence that the jets in these two kinds of sources are similar despite of the very different mass scale of their central engines. Further investigations of the physical origin of these correlations are needed, which can shed light on the nature of the jet physics.

description: We study the long term Kepler light curve of the blazar W2R 1926+42 ($\sim$ 1.6 years) which indicates a variety of variability properties during different intervals of observation. The normalized excess variance, $F_{\rm var}$ ranges from 1.8 % in the quiescent phase and 43.3 % in the outburst phase. We find no significant deviation from linearity in the $F_{\rm var}$-flux relation. Time series analysis is conducted using the Fourier power spectrum and the wavelet analysis methods to study the power spectral density (PSD) shape, infer characteristic timescales and statistically significant quasi-periodic oscillations (QPOs). A bending power law with an associated timescale of $T_B = 6.2^{+6.4}_{-3.1}$ hours is inferred in the PSD analysis. We obtain a black hole mass of $M_\bullet = (1.5 - 5.9) \times 10^7 M_\odot$ for the first time using $F_{\rm var}$ and the bend timescale for this source. From a mean outburst lifetime of days, we infer a distance from the jet base $r \leq 1.75$ pc indicating that the outburst originates due to a shock. A possible QPO peaked at 9.1 days and lasting 3.4 cycles is inferred from the wavelet analysis. Assuming that the QPO is a true feature, $r = (152 - 378)~ G M_\bullet/c^2$ and supported by the other timing analysis products such as a weighted mean PSD slope of $-1.5 \pm 0.2$ from the PSD analysis, we argue that the observed variability and the weak and short duration QPO could be due to jet based processes including orbital features in a relativistic helical jet and others such as shocks and turbulence.

The application of fuzzy hybrid methods has significantly increased in recent years across various sectors. However, the application of fuzzy hybrid methods for modeling systems or processes, such as fuzzy machine learning, fuzzy simulation, and fuzzy decision-making, has been relatively limited in the energy sector. Moreover, compared to standard methods, the benefits of fuzzy-hybrid methods for capturing complex problems are not adequately explored for the solar energy sector, which is one of the most important renewable energy sources in electric grids. This paper investigates the application of fuzzy hybrid systems in the solar energy sector compared to other sectors through a systematic review of journal articles published from 2012 to 2022. Selection criteria for choosing an appropriate method in each investigated fuzzy hybrid method are also presented and discussed. This study contributes to the existing literature in the solar energy domain by providing a state-of-the-art review of existing fuzzy hybrid techniques to (1) demonstrate their capability for capturing complex problems while overcoming limitations inherent in standard modeling methods, (2) recommend criteria for selecting an appropriate fuzzy hybrid technique for applications in solar energy research, and (3) assess the applicability of fuzzy hybrid techniques for solving practical problems in the solar energy sector.

title: Conserving Australia's iconic marsupials; one genome at a time
Creators: name: Brandies, Parice Amber
Publisher: name: University of Sydney
Year: 2021

description: In the midst of a global sixth mass extinction event, conservation initiatives are now more crucial than ever. Australia houses the most diverse range of marsupial species in the world; however, the number that are threatened is growing every year. Genetic management of threatened populations is vital in species recovery, yet incorporation of genetic data in conservation management is currently limited. International and national genome sequencing consortia are currently producing reference genomes for a large variety of species, though there is currently a gap between the creation of these genomic resources and their downstream applications, particularly in conservation contexts. One of the major drivers of this gap is due to the bioinformatic expertise and resources that are required to analyse genomic datasets and to translate the findings into conservation management. This PhD employs a variety of bioinformatic and sequencing approaches to develop genomic resources for threatened Australian Marsupials and demonstrates how these resources can be used as a tool to assist species conservation. The value of genomic data for conservation is demonstrated for a range of species under varying scenarios including: i) using existing genomic datasets for the endangered Tasmanian devil to answer new conservation questions relating to reproduction, ii) creating a reference genome for the common brown antechinus, to act as a model species for its threatened congeneric counterparts and iii) generating and uniting a suite of genomic resources to assist in the management of the vulnerable greater bilby. In addition, ten simple rules for getting started with command-line bioinformatics are presented to facilitate the use of genomic data in wildlife conservation. Bridging the research-implementation gap is essential for harnessing the power of genomic resources for the conservation of threatened species. The findings from this PhD provide crucial steps into bridging this gap.

description: The objective of many high-dimensional microarray and RNA-seq studies is to develop a classifier of cancer patients based on characteristics of their disease. The germinal center B-cell (GCB) classifier study in lymphoma and the National Cancer Institute's Director's Challenge lung (DC-lung) study are two examples. In recent years, such classifiers are often developed using regularized regression, such as the lasso. A critical question is whether a better classifier can be developed from a larger training set size and, if so, how large the training set should be. This paper examines these two questions using an existing sample size method and a novel sample size method developed here specifically for lasso logistic regression. Both methods are based on pilot data. We reexamine the lymphoma and lung cancer data sets to evaluate the sample sizes, and use resampling to assess the estimation methods. We also study application to an RNA-seq data set. We find that it is feasible to estimate sample size for regularized logistic regression if an adequate pilot data set exists. The GCB and the DC-lung data sets appear adequate, under specific assumptions. Existing human RNA-seq data sets are by and large inadequate, and cannot be used as pilot data. Pilot RNA-seq data can be simulated, and the methods in this paper can be used for sample size estimation. A MATLAB program is made available.

description: ESPRESSO is an extremely stable high-resolution spectrograph which is currently being developed for the ESO VLT. With its groundbreaking characteristics it is aimed to be a "science machine", i.e., a fully-integrated instrument to directly extract science information from the observations. In particular, ESPRESSO will be the first ESO instrument to be equipped with a dedicated tool for the analysis of data, the Data Analysis Software (DAS), consisting in a number of recipes to analyze both stellar and quasar spectra. Through the new ESO Reflex GUI, the DAS (which will implement new algorithms to analyze quasar spectra) is aimed to get over the shortcomings of the existing software providing multiple iteration modes and full interactivity with the data.

description: The proposed experiment on 290 volunteers simulates the process of reading a narrative on terrorism — misinformation or accurate information — followed by exposure to official data. Participants that consulted official data following exposure to misinformation (N = 43) did not differ from participants exposed solely to misinformation in regard to the level of worry about terrorism (N = 43). Similarly, there was no significant difference between misinformation (N = 43) and accurate (N = 47) information groups in the level of worry about terrorism after consulting official data. However, the role of deliberate attention and total media consumption have proven essential: when presented with accurate information followed by reliable data, participants’ worry about terrorism decreased significantly, but only for those generally paying maximal attention to news concerning terrorism. Similarly, when presented with misinformation followed by reliable data, participants’ worry significantly increased, but only for those not paying attention to terrorism-related news. Further analyses revealed a polarization effect within the group of participants exposed to inaccurate information and reliable data, with attention paid to terrorism-related news and conservatism as predictors.

description: The dynamics in the thin boundary layers of temperature and velocity is the key to a deeper understanding of turbulent transport of heat and momentum in thermal convection. The velocity gradient at the hot and cold plates of a Rayleigh-Bénard convection cell forms the two-dimensional skin friction field and is related to the formation of thermal plumes in the respective boundary layers. Our analysis is based on a direct numerical simulation of Rayleigh-Bénard convection in a closed cylindrical cell of aspect ratio $Γ=1$ and focused on the critical points of the skin friction field. We identify triplets of critical points, which are composed of two unstable nodes and a saddle between them, as the characteristic building block of the skin friction field. Isolated triplets as well as networks of triplets are detected. The majority of the ridges of line-like thermal plumes coincide with the unstable manifolds of the saddles. From a dynamical Lagrangian perspective, thermal plumes are formed together with an attractive hyperbolic Lagrangian Coherent Structure of the skin friction field. We also discuss the differences from the skin friction field in turbulent channel flows from the perspective of the Poincaré-Hopf index theorem for two-dimensional vector fields.

description: We report on the anisotropic properties of Pauli-limited superconductivity (SC) and antiferromagnetism (AFM) in the solid solutions CeCo(In_{1-x}Zn_x)_5 (x<=0.07). In CeCo(In_{1-x}Zn_x)_5, the SC transition temperature T_c is continuously reduced from 2.3 K (x=0) to ~1.4 K (x=0.07) by doping Zn, and then the AFM order with the transition temperature of T_N~2.2 K develops for x larger than ~0.05. The present thermal, transport and magnetic measurements under magnetic field B reveal that the substitution of Zn for In yields little change of low-temperature upper critical field μ_0H_{c2} for both the tetragonal a and c axes, while it monotonically reduces the SC transition temperature T_c. In particular, the magnitudes of μ_0H_{c2} at the nominal Zn concentration of x = 0.05 (measured Zn amount of ~0.019) are 11.8 T for B||a and 4.8 T for B||c, which are as large as those of pure compound though T_c is reduced to 80% of that for x=0. We consider that this feature originates from a combination of both an enhanced AFM correlation and a reduced SC condensation energy in these alloys. It is also clarified that the AFM order differently responds to the magnetic field, depending on the field directions. For B||c, the clear anomaly due to the AFM transition is observed up to the AFM critical field of ~5 T in the thermodynamic quantities, whereas it is rapidly damped with increasing B for B||a. We discuss this anisotropic response on the basis of a rich variety of the AFM modulations involved in the Ce115 compounds.

The Regulation of Hepatic Choline Transport

description: Choline is an essential nutrient, in the liver it is a precursor necessary for the synthesis of phosphatidylcholine (PC) and is also required as a methyl donor towards the synthesis of betaine and later regeneration of S-adenomethionine (SAM). Choline deficiency is known to trigger the development of non-alcoholic fatty liver disease and affect mitochondrial homeostasis along with a myriad of methylation related regulatory mechanisms. Because of its importance in maintaining liver lipid and mitochondrial homeostasis, choline metabolism has been well characterized with the exception of its transport. The identification of choline transporters has only been recently discovered and because of this, relatively little is known about their expression and regulation. This study has established that choline transporter like proteins 1-5 (CTL1-5) is an intermediate affinity transport system responsible for ~80% of hepatic choline uptake with a smaller percentage accomplished through the low affinity organic cation transporter 1-3/N1-2 (OCT1-3/N1-2) transporters. SLC44A1 expression and choline incorporation have been shown to follow a 24 hour rhythmic trend suggesting the presence of a circadian regulatory mechanism. This finding is supported by the significant decrease in choline expression and aberrant pattern of choline incorporation discovered among rhythmic deficient BMAL-/- mice and through a bioinformatics analysis which revealed the existence of four REV-ERBα consensus sequences. Hepatic SLC44A1 expression and choline incorporation have also been shown to decrease with the onset of obesity. Choline uptake was also shown to decrease following treatment with the free fatty acid oleate. This work increases our knowledge of hepatic choline transport and demonstrates a link between the circadian rhythm and obesity with the hepatic CTL1 transporter.

description: An increasingly important goal of psychiatry is the use of brain imaging data to develop predictive models. Here we present two contributions to statistical methodology for this purpose. First, we propose and compare a set of wavelet-domain procedures for fitting generalized linear models with scalar responses and image predictors: sparse variants of principal component regression and of partial least squares, and the elastic net. Second, we consider assessing the contribution of image predictors over and above available scalar predictors, in particular, via permutation tests and an extension of the idea of confounding to the case of functional or image predictors. Using the proposed methods, we assess whether maps of a spontaneous brain activity measure, derived from functional magnetic resonance imaging, can meaningfully predict presence or absence of attention deficit/hyperactivity disorder (ADHD). Our results shed light on the role of confounding in the surprising outcome of the recent ADHD-200 Global Competition, which challenged researchers to develop algorithms for automated image-based diagnosis of the disorder.
