description: We report analytically known states at non-zero temperature which may serve as a powerful tool to reveal common topological and thermodynamic properties of systems ranging from the QCD phase diagram to topological phase transitions in condensed matter materials. In the holographically dual gravity theory, these are analytic solutions to a five-dimensional non-linear-sigma (Skyrme) model dynamically coupled to Einstein gravity. This theory is shown to be holographically dual to $\mathcal{N}=4$ Super-Yang-Mills theory coupled to an $SU(2)$-current. All solutions are fully backreacted asymptotically Anti-de Sitter~(AdS) black branes or holes. One family of global AdS black hole solutions contains non-Abelian gauge field configurations with positive integer Chern numbers and finite energy density. Larger Chern numbers increase the Hawking-Page transition temperature. In the holographically dual field theory this indicates a significant effect on the deconfinement phase transition. Black holes with one Hawking temperature can have distinct Chern numbers, potentially enabling topological transitions. A second family of analytic solutions, rotating black branes, is also provided. These rotating solutions induce states with propagating charge density waves in the dual field theory. We compute the Hawking temperature, entropy density, angular velocity and free energy for these black holes/branes. These correspond to thermodynamic data in the dual field theory. For these states the energy-momentum tensor, (non-)conserved current, and topological charge are interpreted.

description: Recently, discussion had reemerged over the value of integrated pest and crop management training, through intensive approaches such as farmer field schools or participatory training, as a development approach (Feder et al, 2004). This paper develops a model of human capital accumulation through participatory research and tests several hypotheses on the effectiveness of this approach to increase the adoption of soil conservation and fertility management innovations and improve farm productivity in southeast Asia. Bivariate Probit models with treatment effects are estimated using full information maximum likelihood (Evans and Schwab, 1995: Trost and Lee, 1984) and covariates related to changes in land allocation and productivity, measured before project and after project intervention, are investigates. We follow Greene (1998) to control for simultaneity between adoption and impact by using the predicted adoption decision from the second set of regressions to calculate productivity differentials. Overall, we find that treatment affects associated with the participatory research activities are significant and positive in explaining the differential adoption rates of intercropping, hedgerows, contour ridging, the usage of farm yard manure and chemical fertilizer. The positive relationship between the adoption of soil conservation and fertility management techniques and participation, given very limited productivity impact, may indicated the "value" of the participatory approach to illustrate the social costs of land degradation, sensitize participants towards internalizing these costs, and demonstrate the importance of long-run strategies to preserve land productivity, or both. Secondly, we find that there are additional benefits to participatory research activities that are not embodied in the adoption of soil conservation or fertility management techniques.

description: Quantum cosmological models are commonly described by means of semiclassical approximations in which a smooth evolution of the expectation values of elementary geometry operators replaces the classical and singular dynamics. The advantage of such descriptions is that they are relatively simple and display the classical behavior for large universes. However, they may smooth out an important inner structure and to include it a more detailed treatment is needed. The purpose of the present work is to investigate quantum uncertainty in the basic background variables and its influence on primordial gravitational waves. To this end we quantize a model of the Friedmann-Lemaitre-Robertson-Walker universe filled with a linear barotropic cosmological fluid and with gravitational waves. We carefully derive the dynamical equations for the perturbations in quantum spacetime. The quantization yields an equation of motion for the Fourier modes of gravitational radiation, which is a quantum extension to the usual parametric oscillator equation for gravitational waves propagating in an expanding universe. The two quantum effects from the cosmological background that enter the enhanced equation of motion are (i) a repulsive potential resolving the big bang singularity and replacing it with a big bounce and (ii) uncertainties in the numerical values for the background spacetime dynamical variables. First we study the former effect and its consequences for the primordial amplitude spectrum and carefully discuss the relation between the bounce scale and the physical predictions of the model. Next we investigate the latter effect, in particular the extent to which it may affect the primordial amplitude of gravitational waves. Making use of the WKB approximation we find an analytical formula for the amplitude spectrum as a function of the quantum dispersion of the background spacetime.

description: We propose to accelerate reversal of the ferromagnetic order parameter in spin valves by electronic noise. By solving the stochastic equations of motion we show that the current-induced magnetization switching time is drastically reduced by a modest level of externally generated current (voltage) noise. This also leads to a significantly lower power consumption for the switching process.

description: An Augmented Relative Price Spread (ARPS) model is employed to explain recent changes in real US beef wholesale-retail (WR) and hence farm-retail (FR) marketing margins. It is found that the surge in retail market concentration in 1999 most likely increased retail market oligopsony power relative to wholesale oligopoly power, ultimately changing real US WR beef marketing margins. The finding that higher oligopsony retail market power relative to oligopoly wholesale market power in the US beef industry was most likely responsible for the changes in US WR marketing margins in 1999 is important because it provides an economic justification for policy makers to regulate anticompetitive conduct by beef retailers.
New ladders of success : Sichuan students in the transitional times 1900-1920
Creators: name: Yu, Li
Publisher: name: University of British Columbia
Year: 2009

description: This Dissertation examines Sichuan students' attitude toward modern education in the transitional times. The text describes the intrinsic crisis of the civil service examination system in the late nineteenth century, the establishment of the new school system in the first decade of the twentieth century, and the birth of the first generation of the new political elite in Sichuan after the 1911 Revolution. It highlights the students' participation in the educational reform from their motives of career-seeking and social mobility rather than from their political sentiments such as radicalism, nationalism, and modernization. The study argues that without fundamental social and economic change, educational reform in inland China did not cause a substantial change in the students' traditional attitude towards education. The new school system, substituting for the abolished civil service examination system, functioned as a new ladder of success or a new elite recruiting mechanism for the students. The study suggests that statistical growth did not mean modernity. Tradition played an important role in inland China's modernization movements in the twentieth century by shaping the ways that were used to pursue the aims of the movements and the motives of the people who participate in the movements. Extensive primary documents - ranging from government decrees to local gazetteers - are employed in the study, and attention is paid to the similarities and contrasts between Sichuan and the coastal provinces. Quite a number of tables and a comprehensive bibliography are also included.

description: Panel data has been widely used in many social science studies. Pooling data across cross-sections and time-series improves quality of data analysis; however, the model is limited in its ability to actually accurately predict variables of interest due to severe practical data limitations and the ability of properly capturing varying market structures. In this article, a simple and innovative model of product share is introduced. The Full-Factorial Panel Data Model is based on the simple premises of re-conceptualization of any zero-sum group as a series of two-entity markets. This model solves the challenges associated with pooling data across disparate cross-sections and time-periods as well as the changing competitive market structure issues and therefore results in reliable variable of interest estimates.

description: We suggest that studies on active touch psychophysics are needed to inform the design of haptic musical interfaces and better understand the relevance of haptic cues in musical performance. Following a review of the previous literature on vibrotactile perception in musical performance, two recent experiments are reported. The first experiment investigated how active finger-pressing forces affect vibration perception, finding significant effects of vibration type and force level on perceptual thresholds. Moreover, the measured thresholds were considerably lower than those reported in the literature, possibly due to the concurrent effect of large (unconstrained) finger contact areas, active pressing forces, and long-duration stimuli. The second experiment assessed the validity of these findings in a real musical context by studying the detection of vibrotactile cues at the keyboard of a grand and an upright piano. Sensitivity to key vibrations in fact not only was highest at the lower octaves and gradually decreased toward higher pitches; it was also significant for stimuli having spectral peaks of acceleration similar to those of the first experiment, i.e., below the standard sensitivity thresholds measured for sinusoidal vibrations under passive touch conditions.

description: We present an approach for accurate estimation of the covariance of 2-point correlation functions that requires fewer mocks than the standard mock-based covariance. This can be achieved by dividing a set of mocks into jackknife regions and fitting the correction term first introduced in Mohammad & Percival (2022), such that the mean of the jackknife covariances corresponds to the one from the mocks. This extends the model beyond the shot-noise limited regime, allowing it to be used for denser samples of galaxies. We test the performance of our fitted jackknife approach, both in terms of accuracy and precision, using lognormal mocks with varying densities and approximate EZmocks mimicking the DESI LRG and ELG samples in the redshift range of z = [0.8, 1.2].
 We find that the Mohammad-Percival correction produces a bias in the 2-point correlation function covariance matrix that grows with number density and that our fitted jackknife approach does not. We also study the effect of the covariance on the uncertainty of cosmological parameters by performing a full-shape analysis. We find that our fitted jackknife approach based on 25 mocks is able to recover unbiased and as precise cosmological parameters as the ones obtained from a covariance matrix based on 1000 or 1500 mocks, while the Mohammad-Percival correction produces uncertainties that are twice as large. The number of mocks required to obtain an accurate estimation of the covariance for 2-point correlation function is therefore reduced by a factor of 40-60.

В частности, рассматриваются сложности в определении правового статуса ветеран боевых действий , которые вызваны небесспорной правовой конструкцией, предложенной законодателем; анализируется перечень прав, гарантий и льгот ветеранов боевых действий в ряде стран Западной Европы и Северной Америки; делается вывод о недостаточно разветвленной системе ветеранских движений в России по сравнению с зарубежными странами. Через призму изучения зарубежного опыта также характеризуется основная проблема, существующая на данный момент в РФ, и имеющая практическое значение – отсутствие единого централизованного государственного органа, занимающегося вопросами правовой защиты военнослужащих – ветеранов боевых действий. В этой связи предлагается создание такого учреждения и обосновывается необходимость внедрения единого регистра ветеранов боевых действий, вне зависимости от того, в каких органах они проходили службу, что позволит существенно упростить ведение статистики и наиболее рационально распределять соответствующий бюджет на нужды ветеранов.

description: Kindleia fragosa Jordan, 1927
Kindleia is a common amiid from the Judith River Formation localities but has not been previously reported from the Campanian of Alberta, Montana, and Wyoming. The species was originally described from the upper Edmonton Formation of Alberta. It is now known from the Judith River Formation from an assortment of skull fragments, dentaries, and vertebrae similar to the material from the later Maestrichtian and Paleocene beds of Montana and Alberta. The cranial and post-cranial anatomy has been dealt with in great detail by Estes (1964, pp. 29-35), who made comparisons with Recent Amia calva and found a close resemblance.
A left vomer, AMNH 10109, is referred to Kindleia fragosa. The medial edge is relatively straight, whereas the lateral side has a concave outline. The posterior part of the vomer is broken but was probably elongated in the manner illustrated by Estes (1964, p. 37, fig. 17a, right). The Judith River Formation specimen is larger than the figured specimen from the Lance Formation but is otherwise indistinguishable from that of Paleocene material.
The vomer contains about 13 teeth. The anterior teeth, apparently with the enamel missing or imperfectly developed, are slightly more conical in shape than the posterior teeth. The central and the posterior teeth are pillarlike cylindrical pegs.

description: We present a detailed study of mechanically compliant, photonic-crystal-based microcavities featuring a quasi-bound state in the continuum. Such systems have recently been predicted to reduce the optical loss in Fabry-Perot-type optomechanical cavities. However, they require two identical photonic-crystal slabs facing each other, which poses a considerable challenge for experimental implementation. We investigate how such an ideal system can be simplified and still exhibit a quasi-bound state in the continuum. We find that a suspended photonic-crystal slab facing a distributed Bragg reflector realizes an optomechanical system with a quasi-bound state in the continuum. In this system, the radiative cavity loss can be eliminated to the extent that the cavity loss is dominated by dissipative loss originating from material absorption only. These proposed optomechanical cavity designs are predicted to feature optical quality factors in excess of 10^5.

description: Employing a logit model and farm-level data for Illinois from 1995 to 2004, this study explores the importance of farm-type differences in the development of credit scoring models. Apart from the conclusion that regional credit scoring models specific to each farm type are needed, the following are identified as the most pertinent factors for explaining creditworthiness: previous year's working capital to gross farm return, the debt-to-asset ratio, and return on farm assets. Furthermore, beef farms have a larger marginal effect compared to grain farms on the probability of the farmer being highly creditworthy. Hog farms differ from grain farms in how the following financial characteristics affect farmer creditworthiness: solvency, profitability, and financial efficiency. These separate credit scoring models result in increased expected profit for the lender, better capital management, less bankruptcy, and less burden on the government and tax payers.

Self-optimization, community stability, and fluctuations in two individual-based models of biological coevolution

description: We compare and contrast the long-time dynamical properties of two individual-based models of biological coevolution. Selection occurs via multispecies, stochastic population dynamics with reproduction probabilities that depend nonlinearly on the population densities of all species resident in the community. New species are introduced through mutation. Both models are amenable to exact linear stability analysis, and we compare the analytic results with large-scale kinetic Monte Carlo simulations, obtaining the population size as a function of an average interspecies interaction strength. Over time, the models self-optimize through mutation and selection to approximately maximize a community fitness function, subject only to constraints internal to the particular model. If the interspecies interactions are randomly distributed on an interval including positive values, the system evolves toward self-sustaining, mutualistic communities. In contrast, for the predator-prey case the matrix of interactions is antisymmetric, and a nonzero population size must be sustained by an external resource. Time series of the diversity and population size for both models show approximate 1/f noise and power-law distributions for the lifetimes of communities and species. For the mutualistic model, these two lifetime distributions have the same exponent, while their exponents are different for the predator-prey model. The difference is probably due to greater resilience toward mass extinctions in the food-web like communities produced by the predator-prey model.

Blake (1940) originally reported the genus from the Aquia Formation (lower Eocene) of Maryland. Current investigations, however, have revealed the presence of Paralbula not only in the Judith River Formation, Montana, but also in the Oldman Formation, Alberta. The teeth, which are fairly common in both formations, have been tentatively identified as belonging to? Paralbula sp. (Estes, personal commun.). The Judith River Formation specimens from Clambank Hollow are similar to those obtained from the Oldman Formation and consist of a mixture of thoroughly eroded to well-preserved teeth. The teeth vary in size and shape. Some are round, most are slightly convex, and a few are elongate or rectangular. AMNH 10100 has an average diameter of 2.5 mm. and AMNH 10101 has a length of 3.5 mm. (fig. 7R-U). The attachment surface of the teeth is slightly concave and is characterized by a few concentric layers. The larger teeth comprise the central part of the pharyngeal plate, whereas the smaller, more rounded ones form the peripheral areas. The isolated occurrence of the teeth makes it impossible to decipher the arrangement in which the teeth were stacked, and hence makes comment on their affinity to phyllodonts inadvisable at this time. The affinities and relationships of the Alberta and Montana occurrences of Paralbula are currently under study by Estes, at Boston University.

description: Arrays of individual atoms trapped in optical microtraps with micrometer-scale sizes have emerged as a fundamental, versatile, and powerful platform for quantum sciences and technologies. This platform enables the bottom-up engineering of quantum systems, offering the capability of low-entropy preparation of quantum states with flexible geometry, as well as manipulation and detection at the single-site level. The utilization of ultracold itinerant atoms with tunnel coupling in optical microtraps provides new opportunities for quantum simulation, enabling the exploration of exotic quantum states, phases, and dynamics, which would otherwise be challenging to achieve in conventional optical lattices due to high entropy and limited geometric flexibility. Here the development of tunnel-coupled optical microtraps for the manipulation of ultracold atomic quantum systems and its recent advances are briefly reviewed.

description: HIP 7666 is a variable star newly discovered during the Hipparcos mission and classified as of unknown type (ESA 1997). During 23 nights between July 2000 and November 2000, over 2300 CCD observations in the V band were obtained from Hostalets de Pierola and Monegrillo observatories in Spain. These data show that the new variable is a detached eclipsing binary system with an orbital period of 2.37229 days. In addition, one of the components undergoes very short-period oscillations with a main pulsation frequency of 24.46 or 25.47 c/d. HIP 7666 is therefore a new member of the presently very few known detached eclipsing binary systems with a Delta Scuti type component.

description: Complexity of environmental programs is most apparent with information asymmetries, making the design of efficient mechanisms particularly challenging. As developed theoretically in this paper, a new regulatory capitalism paradigm mating voluntary agreements with environmental education can produce outcomes at least as efficient as voluntary agreements alone. Such a design exploits a key difference between voluntary agreements versus educational programs in terms of their impact on agents' incentive compatibilities. Specifically, in a principal-agent model, voluntary agreements are associated with an incentive-compatibility constraint, whereas educational programs are not. The efficient bundle will likely consist of a set of education programs and voluntary agreements. With the new order of regulatory capitalism, it is time to concentrate on removing barriers yielding inefficient mono-mechanism design and start constructing multidimensional incentives to efficiently allocate effort toward environmental and economic goals.

description: Jets provide one of the primary probes of the quark-gluon plasma produced in ultrarelativistic heavy ion collisions and the cold nuclear matter explored in deep inelastic scattering experiments. However, despite important developments in the last years, a description of the real-time evolution of QCD jets inside a medium is still far from being complete. In our previous work, we have explored quantum technologies as a promising alternative theoretical laboratory to simulate jet evolution in QCD matter, to overcome inherent technical difficulties in present calculations. Here, we extend our previous investigation from the single particle $|q\rangle$ to the $|q\rangle+|qg\rangle$ Fock space, taking into account gluon production. Based on the light-front Hamiltonian formalism, we construct a digital quantum circuit that tracks the evolution of a multi-particle jet probe in the presence of a medium described as a stochastic color field. Studying the momentum broadening of the jet state, we observe sizable sub-eikonal effects by comparing to eikonal estimates. We also study the medium-induced modifications to the gluon emission probability, which exhibit small corrections compared to the vacuum splitting function. In addition, we study the time evolution of the von-Neumann entropy associated with the quark component; we find that the exponential of the entropy grows linearly in time for the bare quark but super-linearly when taking into account gluon emission.

Chiral Tetrahedrons as Unitary Quaternions: Molecules and Particles Under the Same Standard?

description: Chiral tetrahedral molecules can be dealt under the standard of quaternionic algebra. Specifically, non-commutativity of quaternions is a feature directly related to the chirality of molecules. It is shown that a quaternionic representation naturally comes out from empirical Fischer projections and the action of the related algebra on the quantum states of molecules is studied. Analogies with fundamental particle physics are discussed.

description: This article provides an overview of model predictive control (MPC) frameworks for dynamic operation of nonlinear constrained systems. Dynamic operation is often an integral part of the control objective, ranging from tracking of reference signals to the general economic operation of a plant under online changing time-varying operating conditions. We focus on the particular challenges that arise when dealing with such more general control goals and present methods that have emerged in the literature to address these issues. The goal of this article is to present an overview of the state-of-the-art techniques, providing a diverse toolkit to apply and further develop MPC formulations that can handle the challenges intrinsic to dynamic operation. We also critically assess the applicability of the different research directions, discussing limitations and opportunities for further research.

description: We present a time-dependent Langevin description of dynamics of stock prices. Based on a simple sliding-window algorithm, the fluctuation of stock prices is discussed in the view of a time-dependent linear restoring force which is the linear approximation of the drift parameter in Langevin equation estimated from the financial time series. By choosing suitable weighted factor for the linear approximation, the relation between the dynamical effect of restoring force and the autocorrelation of the financial time series is deduced. We especially analyze the daily log-returns of S$&$P 500 index from 1950 to 1999. The significance of the restoring force towards the prices evolution are investigated from its two coefficients, slope coefficient and equilibrium position. The new simple form of the restoring force obtained both from statistical and theoretical analyses suggests that the Langevin approach can effectively present the macroscopical and the detail properties of the price evolution.

Properties of the $η_q$ leading-twist distribution amplitude and its effects to the $B/D^+ \toη^{(\prime)}\ell^+ ν_\ell$ decays

description: The $η^{(\prime)}$-mesons in the quark-flavor basis are mixtures of two mesonic states $|η_{q}\rangle=|\bar u u+\bar d d\rangle/\sqrt 2$ and $|η_{s}\rangle=|\bar s s\rangle$. In the previous work, we have made a detailed study on the $η_{s}$ leading-twist distribution amplitude. As a sequential work, in the present paper, we fix the $η_q$ leading-twist distribution amplitude by using the light-cone harmonic oscillator model for its wave function and by using the QCD sum rules within the QCD background field to calculate its moments. The input parameters of $η_q$ leading-twist distribution amplitude $ϕ_{2;η_q}$ at an initial scale $μ_0\sim 1$ GeV are then fixed by using those moments. The sum rules for the $0_{\rm th}$-order moment can also be used to fix the magnitude of $η_q$ decay constant, which gives $f_{η_q}=0.141\pm0.005$ GeV. As an application of the present derived $ϕ_{2;η_q}$, we calculate the transition form factors $B(D)^+ \toη^{(\prime)}$ by using the QCD light-cone sum rules up to twist-4 accuracy and by including the next-to-leading order QCD corrections to the twist-2 part, and then fix the related CKM matrix element and the decay width for the semi-leptonic decays $B(D)^+ \toη^{(\prime)}\ell^+ ν_\ell$.
