description: Indonesia is an emerging market for beef and cattle exports so estimates of income and price elasticities may help analysts predict future demands. In contrast to developed countries, where meat demand studies often use aggregate data, Indonesian studies rely on household surveys, with unit values (ratios of expenditures to quantities) used instead of market prices. Elasticities estimated from unit values can be subject to various quality and measurement error biases. In this paper, data from 29,000 households on Java are used to estimate a demand system for beef, chicken and other meat groups, and the extent of bias from commonly used estimation strategies is evaluated.

description: Background: The ongoing COVID-19 epidemic dilated rapidly throughout India. To end the global COVID-19 pandemic major behavioral, social distancing, contact tracing, and state interventions has been undertaken to reduce the outbreak and avert the persistence of the coronavirus in humans in India and worldwide. In absence of any vaccine or therapeutics, forecasting is of utmost priority for health care planning and control the transmission of COVID-19. Methods: We have proposed a mathematical model that explain the transmission dynamics of COVID-19 in India. Based on the estimated data our model predicts the evolution of epidemics and the end of SARS-CoV-2 and aids to evaluate the influence of different policies to control the spread of the diseases. Findings: With the real data for infected individuals, we find the basic reproduction number $R_0$ for 17 states of India and overall India. A complete figure is given to demonstrate the estimated pandemic life cycle along with the real data or history to date. Our study reveals that the strict control measures implemented in India substantially mitigated the disseminate of SARS-CoV-2. Importantly, model simulations predict that 95% reduction of outbreak on June 26, 2020 and 99% reduction of outbreak on July 26, 2020 in India. Interpretation: Our model simulation demonstrates that the community-wide elimination of SARS-CoV-2 is possible by mitigating the social distancing and use essential precautions. Lockdown can be implemented strictly to prevent the human-to-human transmission of COVID-19. The model-based and parameter estimation of epidemic life cycle, and end dates, if can be done precisely, may decrease distress and over optimism and develop the mentality for all of us for the next stages of the outbreak evolution.

description: We study the non-equilibrium behavior of the three-dimensional Gaussian random-field Ising model at T=0 in the presence of a uniform external field using a 2-spin-flip dynamics. The deterministic, history-dependent evolution of the system is compared with the one obtained with the standard 1-spin-flip dynamics used in previous studies of the model. The change in the dynamics yields a significant suppression of coercivity, but the distribution of avalanches (in number and size) stays remarkably similar, except for the largest ones that are responsible for the jump in the saturation magnetization curve at low disorder in the thermodynamic limit. By performing a finite-size scaling study, we find strong evidence that the change in the dynamics does not modify the universality class of the disorder-induced phase transition.

description: The van der Waals compound, MnBi$_2$Te$_4$, is the first intrinsic magnetic topological insulator, providing a materials platform for exploring exotic quantum phenomena such as the axion insulator state and the quantum anomalous Hall effect. However, intrinsic structural imperfections lead to bulk conductivity, and the roles of magnetic defects are still unknown. With higher concentrations of same types of magnetic defects, the isostructural compound MnSb$_2$Te$_4$ is a better model system for a systematic investigation of the connections among magnetic, topology and lattice defects. In this work, the impact of antisite defects on the magnetism and electronic structure is studied in MnSb$_2$Te$_4$. Mn-Sb site mixing leads to complex magnetic structures and tunes the interlayer magnetic coupling between antiferromagnetic and ferromagnetic. The detailed nonstoichiometry and site-mixing of MnSb$_2$Te$_4$ crystals depend on the growth parameters, which can lead to $\approx$40\% of Mn sites occupied by Sb and $\approx$15\% of Sb sites by Mn in as-grown crystals. Single crystal neutron diffraction and electron microscopy studies show nearly random distribution of the antisite defects. Band structure calculations suggest that the Mn-Sb site-mixing favors a FM interlayer coupling, consistent with experimental observation, but is detrimental to the band inversion required for a nontrivial topology. Our results suggest a long range magnetic order of Mn ions sitting on Bi sites in MnBi$_2$Te$_4$. The effects of site mixing should be considered in all layered heterostructures that consist of alternating magnetic and topological layers, including the entire family of MnTe(Bi$_2$Te$_3$)$_n$, its Sb analogs and their solid solution.

We perform a deep out-of-sample forecasting comparison analyzing many models that adopt both our preferred leading indicator (GI), the more standard initial claims or combinations of both. We find that models augmented with the GI outperform the traditional ones in predicting the monthly unemployment rate, even in most state-level forecasts and in comparison with the Survey of Professional Forecasters.
Spherical Isothermal Self-Similar Shock Flows

Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We explore self-similar dynamical processes in a spherical isothermal self-gravitational fluid with an emphasis on shocks and outline astrophysical applications of such shock solutions. The previous similarity shock solutions of Tsai & Hsu and of Shu et al. may be classified into two types: Class I solutions with downstream being free-fall collapses and Class II solutions with downstream being Larson-Penston (LP) type solutions. By the analyses of Lou & Shen and Shen & Lou, we further construct similarity shock solutions in the `semi-complete space'. These general shock solutions can accommodate and model dynamical processes of radial outflows (wind), inflows (accretion or contraction), subsonic oscillations, and free-fall core collapses all with shocks in various settings such as star-forming molecular clouds, `champagne flows' in H{\sevenrm II} regions around luminous massive OB stars or surrounding quasars, dynamical connection between the asymptotic giant branch phase to the proto-planetary nebula phase with a central hot white dwarf as well as accretion shocks around compact objects such as white dwarfs, neutron stars, and supermassive black holes. By a systematic exploration, we are able to construct families of infinitely many discrete Class I and Class II solutions matching asymptotically with a static outer envelope of singular isothermal sphere; the shock solutions of Tsai & Hsu form special subsets. These similarity shocks travel at either subsonic or supersonic constant speeds. We also construct twin shocks as well as an `isothermal shock' separating two fluid regions of two different yet constant temperatures.

Then, we pass to examine the equivalence between quantum tunnelling and "photon tunnelling" (evanescent waves propagation), with particular attention to tunnelling with Superluminal group-velocities ("Hartman effect"). At last, in an Appendix, we add a bird-eye view of all the experimental sectors of physics in which Superluminal motions seem to appear.

description: It has become commonly accepted that a successful climate strategy should compound mitigation and adaptation. The accurate combination between adaptation and mitigation that can best address climate change is still an open question. This paper proposes a framework that integrates mitigation, adaptation, and climate change residual damages into an optimisation model. This set-up is used to provide some insights on the welfare maximising resource allocation between mitigation and adaptation, on their optimal timing, and on their marginal contribution to reducing vulnerability to climate change. The optimal mix between three different adaptation modes (reactive adaptation, anticipatory adaptation, and investment in innovation for adaptation purposes) within the adaptation bundle is also identified. Results suggest that the joint implementation of mitigation and adaptation is welfare improving. Mitigation should start immediately, whereas adaptation somehow later. It is also shown that in a world where the probability of climate-related catastrophic events is small and where decision makers have a high discount rate, adaptation is unambiguously the preferred option. Adaptation needs, both in developed and developing countries, will be massive, especially during the second half of the century. Most of the adaptation burden will be on developing countries. International cooperation is thus required to equally distribute the cost of adaptation.

Detectability of Extrasolar Planets in Radial Velocity Surveys

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Radial velocity surveys are beginning to reach the time baselines required to detect Jupiter analogs, as well as sub-Saturn mass planets in close orbits. Therefore it is important to understand the sensitivity of these surveys at long periods and low amplitudes. In this paper, I derive analytic expressions for the detectability of planets at both short and long periods, for circular and eccentric orbits. I suggest an extension of the Lomb-Scargle periodogram for Keplerian orbits, and describe how to estimate the false alarm probability associated with a Keplerian fit. Using this to investigate the detectability of eccentric orbits shows that there are significant selection effects against eccentric orbits for e>0.6, and the small number of highly eccentric planets discovered so far may reflect this. Finally, I present a Bayesian approach to the periodogram, which emphasises the equivalence of least squares and periodogram techniques.

description: We present and evaluate Spectrum-Based Log Diagnosis (SBLD), a method to help developers quickly diagnose problems found in complex integration and deployment runs. Inspired by Spectrum-Based Fault Localization, SBLD leverages the differences in event occurrences between logs for failing and passing runs, to highlight events that are stronger associated with failing runs. Using data provided by our industrial partner, we empirically investigate the following questions: (i) How well does SBLD reduce the effort needed to identify all failure-relevant events in the log for a failing run? (ii) How is the performance of SBLD affected by available data? (iii) How does SBLD compare to searching for simple textual patterns that often occur in failure-relevant events? We answer (i) and (ii) using summary statistics and heatmap visualizations, and for (iii) we compare three configurations of SBLD (with resp. minimum, median and maximum data) against a textual search using Wilcoxon signed-rank tests and the Vargha-Delaney measure of stochastic superiority. Our evaluation shows that (i) SBLD achieves a significant effort reduction for the dataset used, (ii) SBLD benefits from additional logs for passing runs in general, and it benefits from additional logs for failing runs when there is a proportional amount of logs for passing runs in the data. Finally, (iii) SBLD and textual search are roughly equally effective at effort-reduction, while textual search has a slightly better recall. We investigate the cause, and discuss how it is due to the characteristics of a specific part of our data. We conclude that SBLD shows promise as a method for diagnosing failing runs, that its performance is positively affected by additional data, but that it does not outperform textual search on the dataset considered. Future work includes investigating SBLD's generalizability on additional datasets.

description: We classify the non-supersymmetric, and perturbatively stable within $D=4$, AdS vacua of maximal $D=4$ supergravity with a dyonic ISO(7) gauging in a large sector of the supergravity. Seven such vacua are established within this sector, all of them giving rise to non-supersymmetric $\textrm{AdS}_{4} \times \textrm{S}^{6}$ type IIA backgrounds with and without non-trivial warpings and with internal fluxes. Then, we analyse the dynamics of various probe D$p$-branes in these backgrounds searching for potential brane-jet instabilities. In all these cases, such instabilities are absent. Finally, an alternative decay channel through tunnelling is investigated, focusing on one of the seven backgrounds. We do not find instabilities either, but the analysis remains inconclusive.

description: The properties of statistical ensembles with abelian charges close to the thermodynamic limit are discussed. The finite volume corrections to the probability distributions and particle density moments are calculated. Results are obtained for statistical ensembles with both exact and average charge conservation. A new class of variables (semi--intensive variables) which differ in the thermodynamic limit depending on how charge conservation is implemented in the system is introduced. The thermodynamic limit behavior of these variables is calculated through the next to leading order finite volume corrections to the corresponding probability density distributions.

description: Godunov type numerical schemes for the class of hyperbolic systems, admitting non-classical $δ-$ shocks are proposed. It is shown that the numerical approximations converge to the solution and preserve the physical properties of the system such as positive density and bounded velocity. The scheme has been extended to positivity preserving and velocity bound preserving second-order accurate scheme by using appropriate slope limiters. The numerical results are compared with the existing the literature and the scheme is shown to capture the solution efficiently. The paper presents a hyperbolic system, for which an entropy satisfying scheme is constructed through an appropriate decoupling of the system into two scalar conservation laws with discontinuous flux.

description: A complete sample of 18 X-ray selected clusters of galaxies belonging to the ROSAT North Ecliptic Pole (NEP) survey has been observed with the Very Large Array at 1.4 GHz. These are the most distant clusters in the X-ray survey with redshift in the range 0.3 < z < 0.8.Seventy-nine radio sources are detected within half an Abell radius with an observed peak brightness >=0.17 mJy/beam, except for three sources, belonging to the same cluster, which have a higher peak brightness limit of 0.26 mJy/beam. The NEP field source counts are in good agreement with the source counts of a comparison survey, the VLA-VIRMOS deep field survey, indicating that the NEP sample is statistically complete. Thirty-two out of the 79 sources are within 0.2 Abell radii, twenty-two of them are considered cluster members based on spectroscopic redshifts or their optical magnitude and morphological classification. The cluster radio galaxies are used to construct the Radio Luminosity Function (RLF) of distant X-ray selected clusters. A comparison with two nearby cluster RLFs shows that the NEP RLF lies above the local ones, has a steeper slope at low radio powers (<= 10^(24) W/Hz) and shows no evidence for a break at about 6 X 10^(24) W/Hz which is observed in the nearby cluster RLFs. We discuss briefly the origin and possible explanations of the differences observed in the radio properties of nearby and distant clusters of galaxies. The main result of this study is that the RLF of the distant X-ray clusters is very different from that of the local rich Abell clusters.

description: We study a quality-ladder model of endogenous growth that produces stochastic leadership cycles. Over a cycle, industry leaders can innovate several successive times in the same industry, gradually increasing the magnitude of their technological lead before being replaced by a new entrant. Initially, new leaders are eager to enlarge their lead and do much of the research, but if they innovate repeatedly, their propensity to invest in R&D decreases. Eventually they stop doing research altogether, and as they are overtaken a new cycle starts. The model generates a skewed firm size distribution and a deviation from Gibrat’s law that accord with the empirical evidence. We also consider various policy measures, showing that in some cases policy should favour R&D by incumbents, not outsiders, and that stronger patent protection may reduce innovation and growth.

description: Border adjustments are currently discussed to limit the possible adverse impact of climate policies on competitiveness and carbon leakage. We discuss the main choices that will have to be made if the European Union implements such a system alongside with the EU ETS. Although more analysis is required on some issues, on others some design options seem clearly preferable to others. First, the import adjustment should be a requirement to surrender allowances rather than a tax. Second, the general rule to determine the amount of allowances per ton imported should be the product-specific benchmarks that the European Commission is currently elaborating for a different purpose (i.e. to determine the amount of free allowances). Third, this obligation should apply when the exported product is registered at the EU border, and not after the end of the year as is the case for domestic emitters. Fourth, the export adjustment should take the form of a rebate on the amount of allowances a domestic emitter has to surrender. Five, this rebate should equal the above-mentioned product-specific benchmarks, not the emissions of the particular exporting plant or firm. Finally, the adjustment does not have to apply to consumer products but mostly to basic products.

description: Although a global cap-and-trade system is seen by many researchers as the most cost-efficient solution to reduce greenhouse gas emissions, developing countries governments refuse to enter into such a system in the short term. Hence, many scholars and stakeholders, including the European Commission, have proposed various types of commitments for developing countries that appear less stringent, such as sectoral approaches. In this paper, we assess such a sectoral approach for developing countries. More precisely, we simulate two policy scenarios in which developed countries continue with Kyoto-type absolute commitments, whereas developing countries adopt an emission trading system limited to electricity generation and linked to developed countries' cap-and-trade system. In a first scenario, CO2 allowances are auctioned by the government, which distributes the auctions receipts lump-sum to households. In a second scenario, the auction receipts are used to reduce taxes on, or to give subsidies to, electricity generation. Our quantitative analysis, led with a hybrid general equilibrium model, shows that such options provide almost as much emission reductions as a global cap-and-trade system. Moreover, in the second sectoral scenario, GDP losses in developing countries are much lower than with a global cap-and-trade system and so is the impact on the electricity price.

description: In this letter we present the discovery of a very light planetary companion to the star mu Ara (HD160691). The planet orbits its host once every 9.5days, and induces a sinusoidal radial velocity signal with a semi-amplitude of 4.1 m/s, the smallest Doppler amplitude detected so far. These values imply a mass of m2 sini = 14 earth-masses. This detection represents the discovery of a planet with a mass slightly smaller than that of Uranus, the smallest ``ice giant" in our Solar System. Whether this planet can be considered an ice giant or a super-earth planet is discussed in the context of the core-accretion and migration models.

description: Using first-principles approaches we investigate local heating and the inelastic contribution to the current for various alkanethiols sandwiched between metal electrodes. In the absence of good heat dissipation into the bulk electrodes, we find that the local temperature of the alkanethiols is relatively insensitive to their length. This is due to the rates of heating and cooling processes scaling similarly with length. On the other hand, when considering heat dissipation into the bulk electrodes, the local temperature of alkanethiols decreases as their length increases. We also find that the inelastic scattering profile displays an odd-even effect with length which compares well with experimental results. This effect is due to the alternating direction of the CH3 group motion with respect to current flow with increasing C atoms in the chain, and is very sensitive to the structure of the carbon-sulfur-gold bond. Inelastic scattering profiles can therefore help illuminate the bonding configuration of molecules to metallic surfaces.

description: We examine the motives for and consequences of 5,317 failed and completed cross-border acquisitions constituting $619 billion of total activity that were led by government-controlled acquirers over the period from 1990 to 2008. We benchmark this activity at the aggregate country level and also at the deal level with cross-border acquisitions involving corporate acquirers over the same period. We find that government-led deal activity is relatively more intense for geographically-closer countries, but also relatively less sensitive to differences in the level of economic development of the acquirer’s and target’s home countries, in the quality of their legal institutions and accounting standards, and to how stringent are restrictions on FDI flows in their countries. Government-led acquirers are more likely to pursue larger targets with greater growth opportunities and more financial constraints. But, the share-price reactions to the announcements of such acquisitions are not different. Among those deals involving government-controlled acquirers, we do find important differences involving sovereign wealth funds (SWFs). SWF-led acquisitions are less likely to fail, they are more likely to pursue acquirers that are larger in total assets and with fewer financial constraints, and the market reactions to SWF-led acquisitions, while positive, are statistically and economically much smaller. We discuss policy implications in terms of recent regulatory changes in the U.S. and other countries that seek to restrict foreign acquisitions by government-controlled entities.

description: The selection problem of an optimal set of sensors estimating the snapshot of high-dimensional data is considered. The objective functions based on various criteria of optimal design are adopted to the greedy method: D-optimality, A-optimality, and E-optimality, which maximizes the determinant, minimize the trace of inverse, and maximize the minimum eigenvalue of the Fisher information matrix, respectively. First, the Fisher information matrix is derived depending on the numbers of latent state variables and sensors. Then, the unified formulation of the objective function based on A-optimality is introduced and proved to be submodular, which provides the lower bound on the performance of the greedy method. Next, the greedy methods based on D-, A-, and E-optimality are applied to randomly generated systems and a practical data set of global climates. The sensors selected by the D-optimality objective function works better than those by A- and E-optimality with regard to the determinant, trace of the inverse, and reconstruction error, while those by A-optimality works the best with regard to the minimum eigenvalue. On the other hand, the performance of sensors selected by the E-optimality objective function is worse for all indices and reconstruction error. This might be because of the lack of submodularity as proved in the paper. The results indicate that the greedy method based on D-optimality is the most suitable for high accurate reconstruction with low computational cost.

description: Research background: Adequate and sufficient intake of fruits and vegetables has been listed as one of the important avenues for actualizing a healthy living. More so, access to fruits and vegetables through a preference for retail outlets is indispensable to the debate on fruits and vegetable consumption among households. Purpose of the article: The study examines factors influencing the choice of retail outlets and frequency of visits to retail outlets for the purchase of fruits and vegetables. Methods: The study employed multistage sampling to select the respondent for the study. Primary data were collected from 290 respondents through semi-structured questionnaires and were analysed using Descriptive statistics and Multinomial Logistic Regression. Findings & Value added: The results indicate that majority (52.76%) of consumers preferred to purchase fruits and vegetables daily, weekly, and monthly, while 27.59% preferred to purchase fruits and vegetables weekly only. Regarding the choice of retail outlet, most (46.21%) preferred both open market, neighbourhood stores, and supermarkets, while 33.10% preferred open market only for the choice of fruits and vegetables. The results also indicate important and significant factors like household size (p<0.1), number of people working within the household (p<0.05), total household income (p<0.05) that influenced the consumer’s choice of retail outlet for fruits and vegetable. Likewise, important and significant factors such as customer service (p<0.05), sex of consumer (p<0.05), shopping habit (p<0.01) influenced the frequency of visits to fruit and vegetable retail outlets by consumers. The study recommended that retail outlet owners should strive to create a conducive and friendly atmosphere with their customers to engender an enduring customer service experience to encourage customers’ repeat purchases.

description: Are natural resources a source of conflict or stability? Empirical studies demonstrate that rents from natural resources, and in particular oil, are an important source of civil war. Allegedly, resource rents attract rent seekers, which destabilize society. However, there is a large literature on how so-called rentier states manage to pacify opposition groups by handing out special favors. The present paper attempts to bridge the gap between the rent-seeking view of resource rents as a source of conflict and the rentier state view which emphasizes the role of resource rents in promoting peace and stability, and show how one may lead to the other. The mechanism that we highlight relies on the notion that higher rents may activate more interest groups in a power struggle. We demonstrate that the associated increased cost of conflict may in fact promote social stability. The peaceful solution is upheld by a self reinforcing transfer program, in the form of patronage employment. The chance of conflict and rent dissipation in our model is highest for intermediate levels of resource rents, where the government cannot make credible commitments to the opposition groups.

description: The objective of this paper is to separate a target speaker's speech from a mixture of two speakers using a deep audio-visual speech separation network. Unlike previous works that used lip movement on video clips or pre-enrolled speaker information as an auxiliary conditional feature, we use a single face image of the target speaker. In this task, the conditional feature is obtained from facial appearance in cross-modal biometric task, where audio and visual identity representations are shared in latent space. Learnt identities from facial images enforce the network to isolate matched speakers and extract the voices from mixed speech. It solves the permutation problem caused by swapped channel outputs, frequently occurred in speech separation tasks. The proposed method is far more practical than video-based speech separation since user profile images are readily available on many platforms. Also, unlike speaker-aware separation methods, it is applicable on separation with unseen speakers who have never been enrolled before. We show strong qualitative and quantitative results on challenging real-world examples.

description: We employ the modification of the basic Penrose formula in twistor theory, which allows to introduce commuting composite space-time coordinates. It appears that in the course of such modification the internal symmetry SU(2) of two-twistor system is broken to U(1). We consider the symplectic form on two-twistor space, permitting to interpret its 16 real components as a phase-space. After a suitable change of variables such a two-twistor phase space is split into three mutually commuting parts, describing respectively the standard relativistic phase space (8 degrees of freedom), the spin sector (6 degrees of freedom) and the canonical pair angle-charge describing the electric charge sector (2 degrees of freedom). We obtain a geometric framework providing a twistor-inspired 18-dimensional extended relativistic phase space $\mathcal{M}^{18}$. In such a space we propose the action only with first class constraints, describing the relativistic particle characterized by mass, spin and electric charge.

description: We obtain a phase diagram for a trapped two-dimensional ultra-cold Bose gas. We find a critical temperature above which the free energy of a state with a pair of vortices of opposite circulation is lower than the one for a vortex-free Bose-Einstein condensed ground state. We identify three distinct phases which are, in order of increasing temperature; a phase coherent Bose-Einstein condensate, a vortex pair plasma with a fluctuating condensate phase, and a thermal Bose gas. The existence of the vortex pair phase could be verified using current experimental setups.

I feel Canadian : affective practices of nation and nationalism on Canadian television
Creators: name: Bociurkiw, Marusya
Publisher: name: University of British Columbia
Year: 2009

description: In this dissertation, I examine how ideas about the nation are produced via affect, especially Canadian television's role in this discursive construction. I analyze Canadian television as a surface of emergence for nationalist sentiment. Within this commercial medium, U.S. dominance, Quebec separatism, and the immigrant are set in an oppositional relationship to Canadian nationalism. Working together, certain institutions such as the law and the corporation, exercise authority through what I call 'technologies of affect': speech-acts, music, editing. I argue that the instability of Canadian identity is re-stabilized by a hyperbolic affective mode that is frequently produced through consumerism. Delimited within a fairly narrow timeframe (1995 -2002), the dissertation's chronological starting point is the Quebec Referendum of October 1995. It concludes at another site of national and international trauma: media coverage of September 11, 2001 and its aftermath. Moving from traumatic point to traumatic point, this dissertation focuses on moments in televised Canadian history that ruptured, or tried to resolve, the imagined community of nation, and the idea of a national self and national others. I examine television as a marker of an affective Canadian national space, one that promises an idea of 'home'. I discuss several overlapping texts: the television programs themselves, their political and cultural contexts, and their convergence with other forms of media. More specifically, I privilege television's speech acts, its generic repetitions and compulsive returns, particularly in the context of recent trauma theory. As part of the larger text of television, I also ponder the flow- between television and body, between program and commercial, between TV, telephone and internet, and between television and the spaces of home, the workplace, and the street. Using an interdisciplinary methodology informed by post-structuralist thought, and a writing style inflected by autobiographical modes, I argue that collective affect frequently operates in relation to media representations of nationalism, producing national practices framed by a television screen.
