Anisotropic Hall Effect in Single Crystal Heavy Fermion YbAgGe

description: Temperature- and field-dependent Hall effect measurements are reported for YbAgGe, a heavy fermion compound exhibiting a field-induced quantum phase transition, and for two other closely related members of the RAgGe series: a non-magnetic analogue, LuAgGe and a representative, ''good local moment'', magnetic material, TmAgGe. Whereas the temperature dependent Hall coefficient of YbAgGe shows behavior similar to what has been observed in a number of heavy fermion compounds, the low temperature, field-dependent measurements reveal well defined, sudden changes with applied field; in specific for $H \perp c$ a clear local maximum that sharpens as temperature is reduced below 2 K and that approaches a value of 45 kOe - a value that has been proposed as the $T = 0$ quantum critical point. Similar behavior was observed for $H \| c$ where a clear minimum in the field-dependent Hall resistivity was observed at low temperatures. Although at our base temperatures it is difficult to distinguish between the field-dependent behavior predicted for (i) diffraction off a critical spin density wave or (ii) breakdown in the composite nature of the heavy electron, for both field directions there is a distinct temperature dependence of a feature that can clearly be associated with a field-induced quantum critical point at $T = 0$ persisting up to at least 2 K.

description: Spatial synchrony, which can be result of high migration, can increase the risk of regional extinction, and as a result reduce metapopulation persistence. Coupled patch models, based on a within-patch discrete growth model, are used to investigate the impact of predator pursuit (PP) and prey evasion (PE) on spatial synchrony and pattern formation in a metapopulation framework. Results show that PP and PE together can reduce spatial synchrony and thus the improvement of metapopulation persistence. PP and PE on their own do not signi¯cantly contribute towards asynchrony, however, they do contribute towards higher average population sizes, which in turn results in the improvement of metapopulation persistence. Spatially explicit predator-prey systems with local migration without PP and PE can produce self-organized spatial patterns such as spiral waves and circular waves. The e®ect of PP and PE on spatial pattern formation can decrease spatial synchrony and change the spiral and circular waves to spatial chaos which result in asynchrony of neighbouring patches and improve metapopulation persistence.
Regularizations of Action-Complexity for a Pure BTZ Black Hole Microstate

description: In the action-complexity proposal there are two different methods to regularize the gravitational on-shell action, which are equivalent in the framework of AdS/CFT. In this paper, we want to study the equivalence of them for a pure BTZ black hole microstate. The microstate is obtained from a two-sided BTZ black hole truncated by a dynamical timelike ETW brane. Moreover, it is dual to a finite energy pure state in a two-dimensional CFT. We show that if one includes the timelike counterterms inspired by holographic renormalization as well as the Gibbons-Hawking-York term on the timelike boundary of the WDW patch, which exists in one of the regularizations, the coefficients of the UV divergent terms of action-complexity in the two methods become equal to each other. Furthermore, we compare the finite terms of action-complexity in both regularizations, and show that when the UV cutoff surface is close enough to the asymptotic boundary of the bulk spacetime, action-complexities in both regularizations become exactly equal to each other.

description: The spreading of infectious diseases with and without immunization of individuals can be modeled by stochastic processes that exhibit a transition between an active phase of epidemic spreading and an absorbing phase, where the disease dies out. In nature, however, the transmitted pathogen may also mutate, weakening the effect of immunization. In order to study the influence of mutations, we introduce a model that mimics epidemic spreading with immunization and mutations. The model exhibits a line of continuous phase transitions and includes the general epidemic process (GEP) and directed percolation (DP) as special cases. Restricting to perfect immunization in two spatial dimensions we analyze the phase diagram and study the scaling behavior along the phase transition line as well as in the vicinity of the GEP point. We show that mutations lead generically to a crossover from the GEP to DP. Using standard scaling arguments we also predict the form of the phase transition line close to the GEP point. It turns out that the protection gained by immunization is vitally decreased by the occurrence of mutations.

description: Adversarial examples of deep neural networks are receiving ever increasing attention because they help in understanding and reducing the sensitivity to their input. This is natural given the increasing applications of deep neural networks in our everyday lives. When white-box attacks are almost always successful, it is typically only the distortion of the perturbations that matters in their evaluation. In this work, we argue that speed is important as well, especially when considering that fast attacks are required by adversarial training. Given more time, iterative methods can always find better solutions. We investigate this speed-distortion trade-off in some depth and introduce a new attack called boundary projection (BP) that improves upon existing methods by a large margin. Our key idea is that the classification boundary is a manifold in the image space: we therefore quickly reach the boundary and then optimize distortion on this manifold.

description: Functional magnetic resonance imaging (fMRI) is used to extract {\em functional networks} connecting correlated human brain sites. Analysis of the resulting networks in different tasks shows that: (a) the distribution of functional connections, and the probability of finding a link vs. distance are both scale-free, (b) the characteristic path length is small and comparable with those of equivalent random networks, and (c) the clustering coefficient is orders of magnitude larger than those of equivalent random networks. All these properties, typical of scale-free small world networks, reflect important functional information about brain states.

description: Highly variable precipitation in western U.S. rangelands makes it challenging for ranchers to match animal demand to forage supply. Flexible stocking can enhance matching, thereby reducing losses during drought and increasing profit during wet years. Yet the benefits of flexible stocking depend on the availability of highly accurate and applicable seasonal climate outlooks. The availability and skill of seasonal climate outlooks is summarized, revealing shortcomings that make flexible stocking less practical and less beneficial. A new grassland productivity forecast, Grass-Cast, can facilitate flexible stocking by translating climate outlooks into more applicable summer forage outlooks, and its strengths and limitations are described.

description: Farm subsidies are commonly motivated by their promise to help keep families in agriculture and reduce farm structural change. Many of these subsidies are designed to be targeted to smaller farms, and include production caps or more generous funding for smaller levels of activity. Agricultural economists have long studied how such subsidies affect production choices, and resulting farm structure. Traditional econometric models are typically restricted to detecting average effects of subsidies on certain farm types or regions and cannot easily incorporate complex subsidy design or the multi-output, heterogeneous nature of many farming activities. Programming approaches may help address the broad scope of agricultural production but have less empirical measures for behavioral and technological parameters. This paper uses a recurrent neural network and detailed panel data to estimate the effect of subsidies on the structure of Norwegian farming. Specifically, we use the model to determine how the varying marginal subsidies have affected the distribution of Norwegian farms and their range of agricultural activities. We use the predictive capacity of this flexible, multi-output machine learning model to identify the effects of agricultural subsidies on farm activity and structure, as well as their detailed distributional effects.

description: Precise modeling of neutrino interactions on nuclear targets is essential for neutrino oscillations experiments. The modeling of the energy of final state particles in quasielastic (QE) scattering and resonance production on bound nucleons requires knowledge of both the removal energy of the initial state bound nucleon as well as the average Coulomb and nuclear optical potentials for final state leptons and hadrons. We extract the average values of the real part of the nuclear optical potential for final state nucleons ($U_{opt}^{QE}$) as a function of the nucleon kinetic energy from inclusive electron scattering data on nuclear targets ($\bf_{6}^{12}C$+$\bf_{8}^{16}O$, $\bf_{20}^{40}Ca$+$\bf_{18}^{40}Ar$, $\bf_{3}^{6}Li$, $\bf_{18}^{27}Al$, $\bf_{26}^{56}Fe$, $\bf_{82}^{208}Pb$) in the QE region and compare to calculations. We also extract values of the average of the real part of the nuclear optical potential for a $Δ(1232)$ resonance in the final state ($U^Δ_{opt}$) within the impulse approximation. We find that $U^Δ_{opt}$ is more negative than $U_{opt}^{QE}$ with $U^Δ_{opt}\approx$1.5~$U_{opt}^{QE}$ for $\bf_{6}^{12}C$.

title: The geometry of jet bundles, with applications to the calculus of variations
Creators: name: Saunders, David John
Publisher: name: The Open University
Year: 1987

description: This dissertation presents an exposition of the geometric theory of jet bundles, and describes some applications of this theory to the study of certain types of differential equation, principally those associated with the calculus of variations. The detailed structure of this dissertation is as follows. Chapter 1 contains a review of the properties of bundles and their vector fields and differential forms, and also describe the theory of derivations along bundle maps. Chapter 2 contains a coherent account of the theory of jet bundles. It includes a definition of derivations of type h* and v* and the vertical bracket of vector-valued forms, and also describes infinite jets in a way which clarifies the manifold structure of J°° and the properties of smooth functions on this space. Chapter 3 contains a description of the prolongations of bundle maps and of vector fields, and also explains some properties of repeated jets. Chapter 4 contains a definition of jet fields and their associated connections, and a summary of their properties. It also relates the construction of Backlund transformations to jet fields along bundle maps. Chapter 5 contains a brief history of the almost tangent structure on a tangent manifold and a generalisation of this structure to vertical endomorphisms on an arbitrary jet manifold and a vertical vector-valued m-form on a first-order jet manifold. Chapter 6 contains a short summary of the modern approach to Lagrangian and Hamiltonian systems in mechanics. It also includes a construction for a C art an form in higher-order field theories and an explanation of the relationship of integral sections of jet fields to extremals of variational problems. Finally, Chapter 7 contains a discussion of completely integrable evolution equations and their Hamiltonian structure. There is also an explanation of the Kac-Moody algebra interpretation of the Inverse Scattering Transform in terms of higher-order tangent manifolds.

description: A coordinate system is constructed for a general accelerating observer in 1+1 dimensions, and is used to determine the particle density of the massless Dirac vacuum for that observer. Equations are obtained for the spatial distribution and frequency distribution of massless fermions seen by this observer, in terms of the rapidity function of the observer's worldline. Examples that are considered include the uniformly accelerating observer as a limiting case, but do not always involve particle horizons. Only the low frequency limit depends on the possible presence of particle horizons. The rest of the spectrum is `almost thermal' whenever the observer's acceleration is `almost uniform'.

Periodic orbit spectrum in terms of Ruelle--Pollicott resonances
Creators: name: Leboeuf, P.
Publisher: name: arXiv
Year: 2004
Subjects: subject: Chaotic Dynamics (nlin.CD)
subject: FOS: Physical sciences

description: Fully chaotic Hamiltonian systems possess an infinite number of classical solutions which are periodic, e.g. a trajectory ``p'' returns to its initial conditions after some fixed time tau_p. Our aim is to investigate the spectrum tau_1, tau_2, ... of periods of the periodic orbits. An explicit formula for the density rho(tau) = sum_p delta (tau - tau_p) is derived in terms of the eigenvalues of the classical evolution operator. The density is naturally decomposed into a smooth part plus an interferent sum over oscillatory terms. The frequencies of the oscillatory terms are given by the imaginary part of the complex eigenvalues (Ruelle--Pollicott resonances). For large periods, corrections to the well--known exponential growth of the smooth part of the density are obtained. An alternative formula for rho(tau) in terms of the zeros and poles of the Ruelle zeta function is also discussed. The results are illustrated with the geodesic motion in billiards of constant negative curvature. Connections with the statistical properties of the corresponding quantum eigenvalues, random matrix theory and discrete maps are also considered. In particular, a random matrix conjecture is proposed for the eigenvalues of the classical evolution operator of chaotic billiards.

Magnetic manipulation of the paramagnetic liquid within a miscible nonmagnetic liquid is possible by countering density-difference driven convection. The formation of salt fingers caused by double-diffusive convection in a liquid-liquid system of Gd(NO3)3 and Y(NO3)3 solutions can be prevented by the magnetic field gradient force.

We propose a simple model which reproduces many features of the biological system. We show that both the model and the real system exhibit a fractal behavior at small scales, due to the process of migration and dynamical aggregation, followed at large scale by a random percolation behavior due to the coalescence of aggregates. The results are in good agreement with the analysis performed on the experimental data.

Manuals for Translation
Quality Assurance

description: The research for this thesis was focused on whether use of a manual for the translation of a liturgical text can reduce errors in the 1st draft of a translation. For this research, manuals for translators were developed and tested for five hymns chanted for the feast of Theophany: the heirmos of Ode 1, Canon 1; and troparia 1 and 2 of Ode 9 of both canons. The manuals were tested by seven students with no prior translation experience at two Eastern Orthodox Christian theological schools (Kenya and Alaska), two Orthodox priests in Kenya, and two publication specialists in south Korea, who translated into Kikuyu, Maragoli, Swahili, Yupik, or Korean. Based on the results, the following conclusions were made: Use of a liturgical translator’s manual can be effective in both the prevention and detection phases of the translation quality assurance process. Successful use of a manual depends on personal factors associated with people who earned a four-year university degree or higher. Individuals without a university degree can improve their translations through use of a translation for translators (TFT). The quality assurance methods used for Bible translation projects are applicable to liturgical translation projects.

description: The influence of non-minimal coupling of a scalar field and the Gauss-Bonnet term on the inflationary stage of evolution of the universe is investigated in this paper. The main cosmological effects of such a coupling were considered. The deviations between Einstein-Gauss-Bonnet inflation and standard one based on Einstein gravity were determined. The corrections of a weak GB coupling preserving the type of the scalar field potential to standard inflationary models is considered as well.

Publisher: name: Zenodo
Year: 2018

description: The theory of stellar evolution plays a central role in astrophysics as stellar models are used to infer properties for Galactic and Extragalactic stellar populations as well as exoplanetary systems. However, despite decades of experience, stellar models still face major issues linked to transport processes of chemicals and angular momentum. This review will focus on some of the processes responsible for the most sizable uncertainties in stellar models such as for example convection, rotation and mass loss. The presentation will discuss their implementation, their impact on theoretical predictions and how various observational constraints can help us gain insight on the physics inside stars and face the current challenges of the theory of stellar evolution.

description: The frustrated quantum spin system on the distorted diamond chain lattice is investigated using the numerical diagonalization of finite-size clusters and the level spectroscopy analysis. In the previous work this system was revealed to exhibit the 1/3 magnetization plateau due to two different mechanisms depending on the coupling parameters, and the phase diagram at the 1/3 magnetization was obtained. In the present work it is found that the 1/3 magnetization plateau vanishes for sufficiently large $XY$-like coupling anisotropy. The phase diagram based on the level spectroscopy analysis is also presented.

description: At first glance the existence of altruism in nature seems paradoxical. In displaying an altruistic act, an individual incurs some cost to its own fitness. Natural selection favours the fittest individuals and one would expect that genes promoting altruism would be selected against. This report investigates the mechanisms that facilitates the evolution of altruism. Game theory is widely applied in the study of the evolution of altruism and cooperation. We review game theory concepts which occur regularly in the literature and which are important in the study ofthe evolution of cooperation. The Prisoner's Dilemma game capturesthe essence of altruism and is a model often employed in the theoreticalstudy of cooperation. The best strategy for both players in the single round Prisoner's Dillema (PD) game is to defect, but having repeated rounds can lead to the evolution of cooperation. The mechanism by which cooperation is established in this scenario is known as direct reciprocity. Another mechanism which promotes the evolution of cooperation is the non-random interaction of players, called assortment. A couple of factors could influence the assortment of players, one of which is the spatial distribution of players. A model is constructed in which the players in the PD are placed on a lattice. Each player adopts one of two strategies, pure cooperation or pure defection. The players propagate and die out in proportion to how well they do in playing the PD against their neighbours. The model is used to investigate the spatial dynamics of the players and the level of assortment achieved. A simple movement strategy is introduced, whereby players move if they encounter a defector. The effect of this movement on the assortment is investigated. Our results show that by placing the players in the PD on lattice, enough assortment can be gained to allow the persistence of cooperation. An increase in the dispersal parameter leads to a decline in the success of cooperators and a loss in assortment. This suggests that the best movement strategy for cooperators is to have low dispersal rates, while defectors gain a big benefit from higher dispersal rates.
Exploring food literacy in Whitehorse

description: This paper identifies the topic of food literacy as an important aspect of food security. I then explore the breadth of food initiatives currently offered in Whitehorse, Yukon through a secondary content analysis of existing data for evidence of food literacy. The analysis showed that there is a strong foundation of initiatives that can be linked to food literacy in Whitehorse that are positively influencing community life. While there is room for more initiatives encompassing all of the three components of food literacy - food confidence, food wise, and food meaning - alongside further collaboration amongst organizations, the future for “re-establish[ing] the link between ourselves and the food we eat” (Smith, 2009b, p.2) for citizens in Whitehorse is bright. The analysis shows that there are several current initiatives that address some or all of the three components of food literacy and recommendations are made to strengthen what is already in place.
Electric field in hard superconductors with arbitrary cross section and general critical current law

description: The induced electric field $\vec{E}(\vec{x})$ during magnetic flux entry in superconductors with arbitrary cross section $Ω$ and general critical current law, has been evaluated by integration along the vortex penetration paths. Nontrivial flux motion streamlines are obtained from a variational statement of the critical state, which takes the form of an optimization problem on the finite element discretization of $Ω$. The generality of the theory allows to deal with physical conditions not considered before. In particular, it is shown that the boundary condition to be used for determining $\vec{E}$ is the knowledge of the locus E=0 within the sample. This is emphasized for anisotropic materials in which the electric field is not parallel to the surface. Both numerical and analytical evaluations are presented for homogeneous materials with different geometries: convex and concave contours, samples with holes, variable curvature contours, and for anisotropic samples. In the isotropic case, discontinuities in the electric current paths are shown to be related to changing curvature of the sample's surface. Anisotropic samples display the same kind of discontinuities, even for constant surface curvature.

Spin pumping and magnetization dynamics in ferromagnet-Luttinger liquid junctions

Subjects: subject: Strongly Correlated Electrons (cond-mat.str-el)

description: We study spin transport between a ferromagnet with time-dependent magnetization and a conducting carbon nanotube or quantum wire, modeled as a Luttinger liquid. The precession of the magnetization vector of the ferromagnet due for instance to an outside applied magnetic field causes spin pumping into an adjacent conductor. Conversely, the spin injection causes increased magnetization damping in the ferromagnet. We find that, if the conductor adjacent to the ferromagnet is a Luttinger liquid, spin pumping/damping is suppressed by interactions, and the suppression has clear Luttinger liquid power law temperature dependence. We apply our result to a few particular setups. First we study the effective Landau-Lifshitz-Gilbert (LLG) coupled equations for the magnetization vectors of the two ferromagnets in a FM-LL-FM junction. Also, we compute the Gilbert damping for a FM-LL and a FM-LL-metal junction.

description: Smolin has put forward the proposal that the universe fine tunes the values of its physical constants through a Darwinian selection process. Every time a black hole forms, a new universe is developed inside it that has different values for its physical constants from the ones in its progenitor. The most likely universe is the one which maximizes the number of black holes. Here we present a concrete quantum gravity calculation based on a recently proposed consistent discretization of the Einstein equations that shows that fundamental physical constants change in a random fashion when tunneling through a singularity.

description: In the framework of multidimensional $f(R)$ gravity, we study the metrics of compact extra dimensions assuming that our 4D space has the de Sitter metric. Manifolds described by such metrics could be formed at the inflationary and even higher energy scales. It is shown that in the presence of a scalar field, varying in the extra factor space $\mathbb{M}_2$, it is possible to obtain a variety of inhomogeneous metrics in $\mathbb{M}_2$. Each of these metrics leads to a certain value of the 4D cosmological constant $Λ_4$, and in particular, it is possible to obtain $Λ_4 =0$, as is confirmed by numerically obtained solutions. A nontrivial scalar field distribution in the extra dimensions is an important feature of this family of models.

description: The rice consumption in Korea is rapidly decreasing. Moreover It is very likely to import much more rice after rice talks in 2004. In order to improve the competitiveness of domestic rice, it is necessary to build producing and marketing system toward to satisfy consumer's preference. This study concerns the evaluation about the rice price, quality and brand using the consumer survey in 2003, 2004. With increase of the household income, consumers purchase high price rice and consider producing area the important factor as impact on taste. Safety, appearance and certification marks need to establish consumer's trust by strict quality management and promotion. In rice brand part, Imgumnimpyo Icheon rice brand have the power based on high awareness. Rice brand users are required to exert effort to build and raise consumer brand awareness, in the first place.

description: The decomposition of the Solar system abundances of heavy isotopes into their s- and r- components plays a key role in our understanding of the corresponding nuclear processes and the physics and evolution of their astrophysical sites. We present a new method for determining the s- and r- components of the Solar system abundances, fully consistent with our current understanding of stellar nucleosynthesis and galactic chemical evolution. The method is based on a study of the evolution of the solar neighborhood with a state-of-the-art 1-zone model, using recent yields of low and intermediate mass stars as well as of massive rotating stars. We compare our results with previous studies and we provide tables with the isotopic and elemental contributions of the s- and r-processes to the Solar system composition.
