description: We introduce a new simulation and analysis paradigm for Imaging Atmospheric Cherenkov Telescope (IACT) arrays, simulating the actual observation conditions as well as individual telescope configuration for each observation unit. Compared to existing frameworks, where simulations are usually generated using pre-defined settings, this run-wise simulation approach implies more realistic simulations and hence reduced systematic uncertainties. The computational effort of this dedicated simulation concept is notably independent of the amount of different observation configurations but just scales linearly with observation time. This corresponds to a large advantage for increasingly complex current and future IACT arrays where the size of the phase space makes it computationally unfeasible to generate simulations that reach the requirements regarding systematics using the classical simulation scheme.

description: This paper aims to quantify the driving forces behind the observed divergence of Indian economy. The results show that in a closed economy with agriculture as the predominant mode of production, the comparative advantage is mainly determined by the difference in land quality and climate across regions within a country. However, when the economy opens its door to the rest of the world, a region's comparative advantage is evaluated in a broader global context. Therefore, regions adjacent to more developed economies, or with better infrastructure such as ports and airports, enjoy a far better location advantage for trade and development than landlocked regions. More investment in physical infrastructure such as roads will bring the interior regions closer to the world markets and reduce regional disparity. Among all the factors considered, education is the only equalizing factor to regional development.

An analytic model for the transition from decelerated to accelerated cosmic expansion
Creators: name: de Leon, J. Ponce

Year: 2005
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We consider the scenario where our observable universe is devised as a dynamical four-dimensional hypersurface embedded in a five-dimensional bulk spacetime, with a large extra dimension, which is the {\it generalization of the flat FRW cosmological metric to five dimensions}. This scenario generates a simple analytical model where different stages of the evolution of the universe are approximated by distinct parameterizations of the {\it same} spacetime. In this model the evolution from decelerated to accelerated expansion can be interpreted as a "first-order" phase transition between two successive stages. The dominant energy condition allows different parts of the universe to evolve, from deceleration to acceleration, at different redshifts within a narrow era. This picture corresponds to the creation of bubbles of new phase, in the middle of the old one, typical of first-order phase transitions. Taking $Ω_{m} = 0.3$ today, we find that the cross-over from deceleration to acceleration occurs at $z \sim 1-1.5 $, regardless of the equation of state in the very early universe. In the case of primordial radiation, the model predicts that the deceleration parameter "jumps" from $q \sim + 1.5$ to $q \sim - 0.4$ at $z \sim 1.17$. At the present time $q = - 0.55$ and the equation of state of the universe is $w = p/ρ\sim - 0.7 $, in agreement with observations and some theoretical predictions.

description: The radial expansion of coronal mass ejections (CMEs) is known to occur from remote observations; from the variation of their properties with radial distance; and from local in situ plasma measurements showing a decreasing speed profile throughout the magnetic ejecta (ME). However, little is known on how local measurements compare to global measurements of expansion. Here, we present results from the analysis of 42 CMEs measured in the inner heliosphere by two spacecraft in radial conjunction. The magnetic field decrease with distance provides a measure of their global expansion. Near 1 au, the decrease in their bulk speed provides a measure of their local expansion. We find that these two measures have little relation with each other. We also investigate the relation between characteristics of CME expansion and CME properties. We find that the expansion depends on the initial magnetic field strength inside the ME, but not significantly on the magnetic field inside the ME measured near 1 au. This is an indirect evidence that CME expansion in the innermost heliosphere is driven by the high magnetic pressure inside the ME, while by the time the MEs reach 1 au, they are expanding due to the decrease in the solar wind dynamic pressure with distance. We also determine the evolution of the ME tangential and normal magnetic field components with distance, revealing significant deviations as compared to the expectations from force-free field configurations as well as some evidence that the front half of MEs expand at a faster rate than the back half.

description: A bipartite entanglement between two nearest-neighbor Heisenberg spins of a spin-1/2 Ising-Heisenberg model on a triangulated Husimi lattice is quantified using a concurrence. It is shown that the concurrence equals zero in a classical ferromagnetic and a quantum disordered phase, while it becomes sizable though unsaturated in a quantum ferromagnetic phase. A thermally-assisted reentrance of the concurrence is found above a classical ferromagnetic phase, whereas a quantum ferromagnetic phase displays a striking cusp of the concurrence at a critical temperature.

description: The 2-matrix models can be defined in a setting more general than polynomial potentials, namely, the semiclassical matrix model. In this case, the potentials are such that their derivatives are rational functions, and the integration paths for eigenvalues are arbitrary homology classes of paths for which the integral is convergent. This choice includes in particular the case where the integration path has fixed endpoints, called hard edges. The hard edges induce boundary contributions in the loop equations. The purpose of this article is to give the loop equations in that semicassical setting.

description: This paper examines the strategic behavior of firms under emissions taxes and tradable emissions permits designed to mitigate phosphorus emissions. The Nash payoff to the regulator of the strategic game is determined for a sub-basin of the Minnesota River using econometric estimates of cost and benefit functions representative of the region. These payoffs are compared to determine the preferred policy instrument. Results show that emission permits yield lower deadweight losses than emissions taxes.

description: Two-dimensional atomic crystals can radically change their properties in response to external influences such as substrate orientation or strain, resulting in essentially new materials in terms of the electronic structure. A striking example is the creation of flat-bands in bilayer-graphene for certain 'magic' twist-angles between the orientations of the two layers. The quenched kinetic-energy in these flat-bands promotes electron-electron interactions and facilitates the emergence of strongly-correlated phases such as superconductivity and correlated-insulators. However, the exquisite fine-tuning required for finding the magic-angle where flat-bands appear in twisted-bilayer graphene, poses challenges to fabrication and scalability. Here we present an alternative route to creating flat-bands that does not involve fine tuning. Using scanning tunneling microscopy and spectroscopy, together with numerical simulations, we demonstrate that graphene monolayers placed on an atomically-flat substrate can be forced to undergo a buckling-transition, resulting in a periodically modulated pseudo-magnetic field, which in turn creates a post-graphene material with flat electronic bands. Bringing the Fermi-level into these flat-bands by electrostatic doping, we observe a pseudogap-like depletion in the density-of-states, which signals the emergence of a correlated-state. The described approach of 2D crystal buckling offers a strategy for creating other superlattice systems and, in particular, for exploring interaction phenomena characteristic of flat-bands.

description: We investigate the effect of vacancy defects on the electronic and magnetic properties of zigzag graphene nanoribbons (zGNRs) by making use of the Green's function formalism in combination with the tight-binding Hamiltonian. The evolution of the indirect exchange coupling, known as Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction, including single, double, and multiple 5-8-5 divacancy defects is explained. Our numerical calculations show that the changes in the electronic structure and the exchange coupling of zGNRs depend significantly on the location of the divacancy defects with respect to the ribbon edges and on the number of the divacancy defects. In the case both the impurities are located on the edge, the magnitude of the exchange coupling is several orders of magnitude strengthen that result when they are placed on the interior of the nanoribbon. Furthermore, a periodic divacancy causes a dramatic change in the magnetic ground state of the ribbon. In the limit of high vacancy potential, the strength of the RKKY interaction is approximately independent of the Fermi energy.

Studying the analytic structure of the scattering amplitude, we have found that there are two poles lying around energies of Lambda(1405) with different widths and couplings to the meson-baryon states. We discuss reactions to conform the double pole structure in experiment and elastic K^- p scattering at low energies.

Risk assessment for conservation under ecological uncertainty : a case study with a stream-dwelling amphibian in managed forests
Creators: name: Sutherland, Glenn Douglas
Publisher: name: University of British Columbia
Year: 2009

description: Quantifying risks of forest and habitat management options are often limited by uncertainties in habitat associations, life history and population trends for resident species. Using the tailed frog (Ascaphus truei), a headwater stream-dependent amphibian, I: 1) developed hierarchical models of habitat relationships across this species' range in British Columbia; 2) examined plausible life history responses to habitat change, and 3) investigated population persistence outcomes within and among streams to uncertain effects of forest harvesting and disturbance scenarios. To develop habitat association relationships I used classification and regression trees (CART) together with simple and partial Mantel tests. Variables describing biophysical setting at meso- and micro-scales had a greater influence on occurrence and abundance of larval frogs than did adjacent forest practices, possibly because most sampling sites were in disturbed watersheds. Underlying geology was a consistently important determinant of occurrence patterns, with fine-scale stream structure more important in determining abundance. Using life stage-based population matrix models, I explored consequences of different life history strategies and ranges of habitat productivity and environmental variation on population persistence. Persistence is decreasingly sensitive to changes in growth rates, tadpole and adult survival, and fecundity. Populations also appear more sensitive to changes in survivorship of in-stream stages (eggs, hatchlings and tadpoles) than riparian stages (juveniles/adults). Clinal, elevational, and local reductions in habitat productivity (e.g., shorter growing seasons, reduced light penetration in mid-seral forests) appear as dominant factors mediating how local fluctuations in demographic rates determine risks of loss of small populations, even if environmental variation is relatively low. Using a spatially explicit metapopulation-landscape dynamics model, I explored six plausible hypotheses linking habitat alterations to population dynamics in response to forest harvesting and disturbances. Risks to populations from disturbance depend strongly on assumptions about age at first reproduction. Incremental effects of forest harvesting on risks were small compared with those already incurred through stochastic events (floods, debris flows, climatic variation) or state of the landscape. Once extirpated, population recovery through dispersal appears unlikely. However, key uncertainties about the impacts of harvesting and forest succession on demographic rates render evaluation of alternative riparian protection systems difficult with present knowledge.

The disorder represents a relevant perturbation according to the extended Harris criterion. Critical properties of the system are studied by large scale Monte Carlo simulations. The correlation length critical exponent, ν=2.005(5), corresponds to that expected in a system with isotropic correlated long-range disorder, whereas the scaling dimension of the magnetization density, x_m=0.1294(7), is somewhat larger than in the pure system. Conformal properties of the magnetization and energy density profiles are also examined numerically.

We also prove analogues of the Bianchi identities. In particular, we develop a cohomology theory which measures the existence of connections and curvings for $G$-gerbes over stacks. We also introduce $G$-central extensions of groupoids, generalizing the standard groupoid $S^1$-central extensions. As an example, we apply our theory to study the differential geometry of $G$-gerbes over a manifold.

description: Prescribed burning is increasingly being recognized as a useful land management and conservation tool, but with it comes the risk of fire and smoke damage to the property of others. All but two states have codified laws specifying criminal penalties or liability rules for prescribed burning, but the laws in a number of states have changed in recent years or are under review. We develop an economic model of the incentive and welfare effects of prescribed burning and the use of prior regulation and post liability as instruments to address potential external damage from the use of prescribed fire.

We find that the system exhibits similar characteristics of the Ising-class phase transition and the critical value of the control parameter, which is the total atomic number, can be calculated. In particular, the collective effect of the laser shadow becomes dominant at large atomic number, which is responsible for the population asymmetry of the dynamic two-state system. This study may be useful for investigation of dynamic phase transition and temporal behaviour of critical phenomena.

description: The cylindrical Taylor Interpolation through FFT (TI-FFT) algorithm for computation of the near-field and far-field in the quasi-cylindrical geometry has been introduced. The modal expansion coefficient of the vector potentials ${\bf F}$ and ${\bf A}$ within the context of the cylindrical harmonics (TE and TM modes) can be expressed in the closed-form expression through the cylindrical addition theorem. For the quasi-cylindrical geometry, the modal expansion coefficient can be evaluated through FFT with the help of the Taylor Interpolation (TI) technique. The near-field on any arbitrary cylindrical surface can be obtained through the Inverse Fourier Transform (IFT). The far-field can be obtained through the Near-Field Far-Field (NF-FF) transform. The cylindrical TI-FFT algorithm has the advantages of $\mathcal{O} \left( \hbox{N} \log_2 \hbox{N} \right)$ computational complexity for $\hbox{N} = \hbox{N}_ϕ\times \hbox{N}_z$ computational grid, small sampling rate (large sampling spacing) and no singularity problem.

description: Wychowanie do zachowań etycznych jest ważnym elementem w rozwoju dzieci wieku przedszkolnego. Dziecko zachowań etycznych uczy się od osób znaczących w jego życiu (rodziców, nauczycieli). W tym okresie potrzebuje, poprzez zabawę, zrozumieć otaczające wartości i interakcje społeczne. Przechodzi z charakterystycznego dla wczesnego dzieciństwa skupienia na sobie, na etap, w którym zestawia swoje potrzeby z potrzebami innych na tle społecznie akceptowanych zachowań. Postawy etyczne dzieci kształtowane są w wyniku oddziaływań wychowawczych. Jedną z nich jest metoda Ruchu Rozwijającego Weroniki Sherborne (Sherborne Developmental Movement, skr. SDM), która wspiera rozwój psychomotoryczny dzieci. W edukacji SDM oferuje możliwość rozumienia i rozpoznawania emocji i stanów mentalnych innych ludzi, co sprzyja rozwojowi empatii i uczuć moralnych, a także uczy komunikować swoje potrzeby i rozumieć komunikaty innych osób. Szczególna wartość Ruchu Rozwijającego polega na tym, że jest pomocna w rozwijaniu komunikacji, co sprawia, że zabawy nabierają dla dzieci nowych znaczeń. Zabawy relacyjne („z”, „przeciwko” i „razem”) W. Sherborne stanowią nieocenione źródło wychowania do zachowań moralnych. Zestawiając teorię rozwoju moralnego J. Piageta z Metodą Ruchu Rozwijającego zauważamy, że SDM jest narzędziem, które można zastosować w każdych warunkach, aby wspierać rozwój moralny uczestników zajęć poprzez komunikację werbalną i niewerbalną. Ruch Rozwijający umożliwia uczestników reagować na wokalizację i wypowiedzi słowne, odczytywać mowę ciała i reagować na nią, a także podkreśla pozytywną komunikację w sytuacjach etycznie trudnych dla dzieci.

description: A dedicated front-end electronics has been developed for the trigger chambers of the ALICE muon spectrometer which will work at the future LHC at CERN. These trigger chambers are based on RPCs (Resistive Plate Chambers) working in streamer mode. The number of electronics channels (about 21000) and the fact that RPC pulsed signals have specific characteristics have led to design a 8 channels front-end ASIC using a new discrimination technique. The principle of the ASIC is described and the radiation hardness is discussed. Special emphasis is put on production characteristics of about 4000 chips.

description: This paper examines the effects of financial decsion on production, input demands, profitability, and productivityis in U.S. food manufacturing industry. Empirical results shows that output supply, variable input demands, profitability and productivity are affected by agency costs of debt and signaling benefits of dividend payments. Positive contribution of signalling benefits of dividend payments was more than offset by the negative effects of agency cost of debt in TFP growth.

description: We construct exact non-trivial ground states of spin-2 quantum antiferromagnets on the hexagonal lattice. Using the optimum ground state approach we determine the ground state in different subspaces of a general spin-2 Hamiltonian consistent with some realistic symmetries. These states, which are not of simple product form, depend on two free parameters and can be shown to be only weakly degenerate. We find ground states with different types of magnetic order, i.e. a weak antiferromagnet with finite sublattice magnetization and a weak ferromagnet with ferrimagnetic order. For the latter it is argued that a quantum phase transition occurs within the solvable subspace.

description: The paper presents late time cosmology in $f(Q,T)$ gravity where the dark energy is purely geometric in nature. We start by employing a well motivated $f(Q,T)$ gravity model, $f(Q,T)=mQ^{n}+bT$ where $m,n$ and $b$ are model parameters. Additionally we also assume the universe to be dominated by pressure-less matter which yields a power law type scale factor of the form $% a(t)=c_{2}(At+c_{1})^{\frac{1}{A}}$, where $A=\dfrac{3(8π+b)}{n(16π+3b)% }$ and $c_{1}$ \& $c_{2}$ are just integration constants. To investigate the cosmological viability of the model, constraints on the model parameters were imposed from the updated 57 points of Hubble data sets and 580 points of union 2.1 compilation supernovae data sets. We have thoroughly investigated the nature of geometrical dark energy mimicked by the parametrization of $f(Q,T)=mQ^{n}+bT$ with the assistance of statefinder diagnostic in $\{s,r\}$ and $\{q,r\}$ planes and also performed the $Om$ -diagnostic analysis. The present analysis makes it clear-cut that $f(Q,T)$ gravity can be promising in addressing the current cosmic acceleration and therefore a suitable alternative to the dark energy problem. Further studies in other cosmological areas are therefore encouraging to further investigate the viability of $f(Q,T)$ gravity.

description: The photoluminescence in amorphous semiconductors decays according to power law $t^{-delta}$ at long times. The photoluminescence is controlled by dispersive transport of electrons. The latter is usually characterized by the power $alpha$ of the transient current observed in the time-of-flight experiments. Geminate recombination occurs by radiative tunneling which has a distance dependence. In this paper, we formulate ways to calculate reaction rates and survival probabilities in the case carriers execute dispersive diffusion with long-range reactivity. The method is applied to obtain tunneling recombination rates under dispersive diffusion. The theoretical condition of observing the relation $delta = alpha/2 + 1$ is obtained and theoretical recombination rates are compared to the kinetics of observed photoluminescence decay in the whole time range measured.

Myocardial glycogen metabolism and its regulation

description: Introduction: Although glycogen metabolism has received much research attention, many unanswered questions regarding the contribution of glycogen to myocardial energy production and the regulation of cardiac glycogen metabolism remain. Glycogen use plays an important role in heart function, especially during periods of stress such as increased work and ischemia. Understanding the contribution of glycogen to myocardial energy metabolism and its regulation are essential in order to alter its metabolism to improve heart function. Purpose: The studies in this thesis are designed to test the hypotheses that glycogen contributes significantly to myocardial energy production under non-stressful conditions, that alterations in myocardial glycogen turnover (i.e. simultaneous synthesis and degradation) occur in association with changes in the activity of 5'AMP-activated protein kinase (AMPK), and that activation of AMPK by 5-aminoimidazole-4-carboxamide 1-β-D-ribofuranoside (AICAR) stimulates long-chain but not medium chain fatty acid oxidation by inhibiting acetyl CoA carboxylase, and stimulates cardiac glycogenolysis by stimulating glycogen phosphorylase (GP) and inhibiting glycogen synthase (GS). Methods: All studies were performed using the isolated working rat heart preparation. A new protocol was developed which allowed the direct measurement of glycolysis and glucose oxidation, both of glucose and glycogen. Results: Myocardial glycogen contributes significantly to myocardial energy production, is oxidized preferentially relative to exogenous glucose, undergoes substantial turnover (i.e. simultaneous synthesis and degradation) and is degraded in a random, rather than ordered, fashion. Further, the depletion of glycogen stores inhibits both glycogen degradation and glycogen turnover, while alterations in workload affect primarily glycogen degradation and not synthesis. Long-chain (palmitate), but not medium-chain (octanoate) fatty acid oxidation is significantly increased in the presence of AICAR. AMPK activation by AICAR did not alter glycogen content, GP or GS activity under the conditions examined. Conclusions: Glycogen contributes significantly to energy production under non-stressful conditions. Glucose from glycogen is preferentially oxidized compared to exogenous glucose Glycogen turnover occurs during periods of net glycogen degradation, but not during periods of net glycogen synthesis. AICAR activation of AMPK stimulates myocardial long-chain, but not medium-chain, fatty acid oxidation and does not alter glycogen content, or the activities of GP and GS under the conditions examined.
Hybrid Open-Loop Closed-Loop Control of Coupled Human-Robot Balance During Assisted Stance Transition with Extra Robotic Legs

description: A new approach to the human-robot shared control of the Extra Robotic Legs (XRL) wearable augmentation system is presented. The XRL system consists of two extra legs that bear the entirety of its backpack payload, as well as some of the human operator's weight. The XRL System must support its own balance and assist the operator stably while allowing them to move in selected directions. In some directions of the task space the XRL must constrain the human motion with position feedback for balance, while in other directions the XRL must have no position feedback, so that the human can move freely. Here, we present Hybrid Open-Loop / Closed-Loop Control Architecture for mixing the two control modes in a systematic manner. The system is reduced to individual joint feedback control that is simple to implement and reliable against failure. The method is applied to the XRL system that assists a human in conducting a nuclear waste decommissioning task. A prototype XRL system has been developed and demonstrated with a simulated human performing the transition from standing to crawling and back again while coupled to the prototype XRL system.

description: Osoby poddane izolacji domowej z powodu choroby COVID-19 znajdują się w trudnej sytuacji. Z jednej strony towarzyszy im obawa związana bezpośrednio z chorobą (czy i kiedy będą w stanie się wyleczyć), z drugiej uniemożliwienie opuszczania własnego domu w celu nawet załatwienia podstawowych spraw powoduje pogłębienie bezradności. Ludzie w takiej sytuacji są wręcz skazani na pomoc z zewnątrz. Tekst przywołuje doświadczenia osób zarażonych koronawirusem w zakresie wparcia społecznego jakie otrzymywali będąc chorymi na Covid-19.

Modeling Agricultural Trade Liberalization. A Review.

Publisher: name: Unknown
Year: 2001
Subjects: International Relations/Trade

description: The paper reviews the models used in the past 10 years or so to analyze the expected effects of liberalizing agricultural trade. The main aim of the paper it to provide the reader with an overview of models which have been used to assess, first, during the Uruguay Round, the implications of alternative hypothetical trade liberalization scenarios, then, the Agreement itself, and, more recently, the implications of further steps in liberalizing agricultural markets as a result of the on going WTO negotiations. The conclusion reached is that the efforts to model agricultural trade and trade policies, taken as a whole, are not fully satisfactory. Although several models offer accurate representations of international agricultural markets and trade policies, many others, including several developed and used by governments and relevant multilateral institutions, are structurally incapable of providing reliable answers to some of the policy questions they are asked to address. The final part of the paper identifies priorities for actions to be taken for improving modeling of trade policies and WTO commitments.

description: We find a new class of Hopf algebras, local quasitriangular Hopf algebras, which generalize quasitriangular Hopf algebras. Using these Hopf algebras, we obtain solutions of the Yang-Baxter equation in a systematic way. The category of modules with finite cycles over a local quasitriangular Hopf algebra is a braided tensor category.

The allocative efficiency measure is then used to determine if allowance prices actually reflect opportunity costs.
Nervous Excitability dynamics in a multisensory syndrome and its similitude with a normal state. Scaling Laws

description: In the context of increased number of works published on multisensory and cross-modal effects, we review a cortical multisensory syndrome (called central syndrome) associated with a unilateral parieto-occipital lesion in a rather unspecific (or multisensory) zone of the cortex. The patients with this syndrome suffered from bilateral and symmetric multisensory disorders dependent on the extent of nervous mass lost and the intensity of the stimulus. They also presented cross-modal effects. A key point is the similitude of this syndrome with a normal state, since this syndrome would be the result of a scale reduction in brain excitability. The first qualities lost when the nervous excitation diminishes are the most complex ones, following allometric laws proper of a dynamic system. The inverted perception (visual, tactile, auditive) in this syndrome is compared to other cases of visual inversion reported in the literature. We focus on the capability of improving perception by intensifying the stimulus or by means of another type of stimulus (cross-modal), muscular effort being one of the most efficient and least known means. This capability is greater when nervous excitability deficit (lesion) is greater and when the primary stimulus is weaker. Thus, in a normal subject, this capability is much weaker although perceptible for functions with high excitability demand. We also review the proposed scheme of functional cortical gradients whereby the specificity of the cortex is distributed with a continuous variation leading to a brain dynamics model accounting for multisensory or cross-modal interactions. Perception data (including cross-modal effects) in this syndrome are fitted using Stevens' power law which we relate to the allometric scaling power laws dependent on the active neural mass, which seem to be the laws governing many biological neural networks.
