description: Data from the end of the second World War (1945) to the 1987 production year were used to quantify the pace of change in the structure of farni(ng with regard to labour. Where possible explanations of certain parameters arc put forward with the aim of identifying the economic problem with regard to farm labour. Two structural trends in South African commercial maize production are evident in the summer rainfall areas. The period 1945-1970 witnessed a large expansion in cultivated farm area, probably because tractors replaced draught o»en. Larger areas could be managed and more labour was required. Demands on labour for harvesting were heavy until the introductio. n. of the combine harvester. alleviated .this problem. These trends were strengthened by policies aimed at lowering the costs of capital, g1vmg nse to some of the soc10-econon11c concerns expressed in this paper. In the winter rainfall region where wheat is cultivated the e,-pansion in cultivated area took place before 1945. The period under consideration (1945-1987) therefore only saw the substitution of labour for machinery, especially in the period 1945-1970. It thus seems as if labour related developments in the summer rainfall area trailed that in the winter rainfall area.

description: We point out that the amplitudes for the decays $\bar{B}^0 \to D_s^+ D_s^-$ and $\bar{B}^0_s \to D^+ D^-$ have no factorizable contributions. If one or two of the $D$-mesons in the final state are vectors (i.e $D^*$ 's) there are relatively small factorizable contributions through the annihilation mechanism. The dominant contributions to the decay amplitudes arise from chiral loop contributions and $1/N_c$ suppressed tree level. We predict that the branching ratios for the processes $\bar B^0_d \to D_s^+ D_s^-$, $\bar B^0_d \to D_s^{+*} D_s^- $ and $\bar B^0_d \to D_s^+ D_s^{-*}$ are all of order $(2- 3) \times 10^{-4}$, while $\bar B^0_s \to D_d^+ D_d^-$, $\bar B^0_s \to D_d^{+*} D_d^- $ and $\bar B^0_s \to D_d^+ D_d^{-*}$ are of order $(4- 7) \times 10^{-3}$. If {\em both} $D$-mesons in the final state are $D^*$'s, we obtain branching ratios of order two times bigger.

description: The relativistic Boltzmann equation for a constant differential cross section and with periodic boundary conditions is considered. The speed of light appears as a parameter $c>c_0$ for a properly large and positive $c_0$. A local existence and uniqueness theorem is proved in an interval of time independent of $c>c_0$ and conditions are given such that in the limit $c\to +\infty$ the solutions converge, in a suitable norm, to the solutions of the non-relativistic Boltzmann equation for hard spheres.

description: We calculate exactly the Casimir force or dispersive force, in the non-retarded limit, between a spherical nanoparticle and a substrate beyond the London's or dipolar approximation. We find that the force is a non-monotonic function of the distance between the sphere and the substrate, such that, it is enhanced by several orders of magnitude as the sphere approaches the substrate. Our results do not agree with previous predictions like the Proximity theorem approach.

description: Microwave pulses are used ubiquitously to control and measure qubits fabricated on superconducting circuits. Due to continual environmental coupling, the qubits undergo decoherence both when it is free and during its interaction with the microwave pulse. As quantum logic gates are executed through pulse-qubit interaction, we study theoretically the decoherence-induced effects during the interaction, especially the variations of the pulse, under a dissipative environment with linear spectral distribution. We find that a transmissible pulse of finite width adopts an asymmetric multi-hump shape, due to the imbalanced pumping and emitting rates of the qubit during inversion when the environment is present. The pulse shape reduces to a solitonic pulse at vanishing dissipation and a pulse train at strong dissipation. We give detailed analysis of the environmental origin from both the perspectives of envelope and phase of the propagating pulse.
High-energy Emission from Pulsar Outer Magnetospheres

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate a stationary pair production cascade in the outer magnetosphere of an isolated, spinning neutron star. The charge depletion due to global flows of charged particles, causes a large electric field along the magnetic field lines. Migratory electrons and/or positrons are accelerated by this field to radiate gamma-rays via curvature and inverse-Compton processes. Some of such gamma-rays collide with the X-rays to materialize as pairs in the gap. The replenished charges partially screen the electric field, which is self-consistently solved together with the energy distribution of particles and gamma-rays at each point along the field lines. By solving the set of Maxwell and Boltzmann equations, we demonstrate that an external injection of charged particles at nearly Goldreich-Julian rate does not quench the gap but shifts its position and that the particle energy distribution cannot be described by a power-law. The injected particles are accelerated in the gap and escape from it with large Lorentz factors. We show that such escaping particles migrating outside of the gap contribute significantly to the gamma-ray luminosity for young pulsars and that the soft gamma-ray spectrum between 100 MeV and 3 GeV observed for the Vela pulsar can be explained by this component. We also discuss that the luminosity of the gamma-rays emitted by the escaping particles is naturally proportional to the square root of the spin-down luminosity.

description: We study collective attention paid towards hurricanes through the lens of $n$-grams on Twitter, a social media platform with global reach. Using hurricane name mentions as a proxy for awareness, we find that the exogenous temporal dynamics are remarkably similar across storms, but that overall collective attention varies widely even among storms causing comparable deaths and damage. We construct `hurricane attention maps' and observe that hurricanes causing deaths on (or economic damage to) the continental United States generate substantially more attention in English language tweets than those that do not. We find that a hurricane's Saffir-Simpson wind scale category assignment is strongly associated with the amount of attention it receives. Higher category storms receive higher proportional increases of attention per proportional increases in number of deaths or dollars of damage, than lower category storms. The most damaging and deadly storms of the 2010s, Hurricanes Harvey and Maria, generated the most attention and were remembered the longest, respectively. On average, a category 5 storm receives 4.6 times more attention than a category 1 storm causing the same number of deaths and economic damage.

Effects of Differential Strategies of Emotion Regulation

description: Patients suffering from mental disorders, especially anxiety disorders, are often impaired by inadequate emotional reactions. Specific aspects are the insufficient perception of their own emotional states and the use of dysfunctional emotion regulation strategies. Both aspects are interdependent. Thus, Cognitive Behavioral Therapy (CBT) comprises the development and training of adequate emotion regulation strategies. Traditionally, reappraisal is the most common strategy, but strategies of acceptance are becoming more important in the course of advancing CBT. Indeed, there is evidence that emotion regulation strategies differ in self-reported effectiveness, psychophysiological reactions, and underlying neural correlates. However, comprehensive comparisons of different emotion regulation strategies are sparse. The present study, therefore, compared the effect of three common emotion regulation strategies (reappraisal, acceptance, and suppression) on self-reported effectiveness, recollection, and psychophysiological as well as electroencephalographic dimensions. Twenty-nine healthy participants were instructed to either reappraise, accept, suppress, or passively observe their upcoming emotional reactions while anxiety- and sadness-inducing pictures were presented. Results showed a compelling effect of reappraisal on emotional experience, skin conductance response, and P300 amplitude. Acceptance was almost as effective as reappraisal, but led to increased emotional experience. Combining all results, suppression was shown to be the least effective but significantly decreased emotional experience when thoughts and feelings had to be suppressed. Moreover, results show that greater propensity for rumination differentially impairs strategies of emotion regulation.

description: With the explosion of online news, personalized news recommendation becomes increasingly important for online news platforms to help their users find interesting information. Existing news recommendation methods achieve personalization by building accurate news representations from news content and user representations from their direct interactions with news (e.g., click), while ignoring the high-order relatedness between users and news. Here we propose a news recommendation method which can enhance the representation learning of users and news by modeling their relatedness in a graph setting. In our method, users and news are both viewed as nodes in a bipartite graph constructed from historical user click behaviors. For news representations, a transformer architecture is first exploited to build news semantic representations. Then we combine it with the information from neighbor news in the graph via a graph attention network. For user representations, we not only represent users from their historically clicked news, but also attentively incorporate the representations of their neighbor users in the graph. Improved performances on a large-scale real-world dataset validate the effectiveness of our proposed method.

description: We study analytically and numerically dynamics and eigenstates of two electrons with Coulomb repulsion on a tight-binding lattice in one and two dimensions. The total energy and momentum of electrons are conserved and we show that for a certain momentum range the dynamics is exactly reduced to an evolution in an effective narrow energy band where the energy conservation forces the two electrons to propagate together through the whole system at moderate or even weak repulsion strength. We argue that such a mechanism of electron pair formation by the repulsive Coulomb interaction is rather generic and that it can be at the origin of unconventional superconductivity in twisted bilayer graphene.

description: In order to alleviate the ecological footprint of Pie R Squared, the implementation of a cheese-less pizza into the current menu was pursued as a potential solution. Through conducting a pizza sampling survey, statistically significant data prove this strategy to be a viable option. Results indicate high consumer acceptance thus a high sales potential for the cheese-less pizza. In addition to having a lower ecological footprint, cheese-less pizza is vegan, lactose-free, has fewer calories and saturated fat, and has a great taste and appearance. Other strategies in lowering the ecological footprint of Pie R Squared focus on decreasing the amount of cheese and meat served by the outlet. Recommendations are made for Pie R Squared on how to implement the cheese-less pizza to promote sustainability, as other recommendations are made to future AGSC 450 students to further expand on current findings of the Food System Project.

description: This paper derives optimal commodity tax rules for general equilibrium models with imperfect competition. This is achieved by constructing functions for each imperfectly competitive industry describing the effect of taxation upon prices and profits, the construction is applicable to most forms of imperfect competition. Intermediate goods prices appear as important determinants of tax rates and it is shown that the implication of the Diamond-Mirrlees theorem, that intermediate goods remain untaxed, is inapplicable when the competitive assumption is relaxed.

description: We present a systematic comparison of different approaches for the modeling of $t\bar{t}γ$ final states with leptonic decays at the LHC. On the one hand, we consider a complete calculation at NLO QCD accuracy which includes all resonant and non-resonant diagrams. On the other hand, we consider predictions in the narrow-width approximation with top quark decays modeled at various accuracies. In this way we quantify the impact of the off-shell effects in $t\bar{t}γ$ production. We also discuss the relative importance of double-, single- and non-resonant contributions in the complete calculation. Finally we investigate the fraction of isolated photons from decays of top quarks, which represent a background for measurements of anomalous $tγ$ couplings.

High energy gamma ray counterparts of astrophysical sources of ultra-high energy cosmic rays

description: If ultra-high energy cosmic rays (UHECRs) are accelerated at astrophysical point sources, the identification of such sources can be achieved if there is some kind of radiation at observable wavelengths that may be associated with the acceleration and/or propagation processes. No radiation of this type has so far been detected or at least no such connection has been claimed. The process of photopion production during the propagation of UHECRs from the sources to the Earth results in the generation of charged and neutral pions. The neutral (charged) pions in turn decay to gamma quanta and electrons that initiate an electromagnetic cascade in the universal photon background. We calculate the flux of this gamma radiation in the GeV-TeV energy range and find that for source luminosities compatible with those expected from small scale anisotropies in the directions of arrival of UHECRs, the fluxes can be detectable by future Cerenkov gamma ray telescopes, such as VERITAS and HESS, provided the intergalactic magnetic field is not larger than $\sim 10^{-10}$ Gauss and for source distances comparable with the loss length for photopion production.

description: We examine the determination of spot and futures prices in rational expectations equilibrium in a model with three groups of agents, agricultural producers, processing firms and speculators. We find necessary and sufficient conditions for producers to be short, processors to be long, and for the futures price to lie below the expected future spot price (normal backwardation). The conditions impose plausible restrictions on demand elasticities, and on the elasticity of substitution in the processing technology. We use a new technique of analysis which, in contrast to much of the literature does not require restrictive assumptions to be imposed upon the structure of preferences. This paper is circulated for discussion purposes only and its contents should be considered preliminary.

description: The paper presents a simple pairwise meetings model of trade. The new feature is that agents have asymmetric information about the true state of the world. The focus is on the transmission of the information through the process of trade. The qualitative questions is: to what extent is the information revealed to uninformed agents through the trading process, when the market is in some sense frictionless? In particular: does the decentralized process give rise to full revelation results as derived by the literature on rational expectations for centralized and competitive environments? In the context of the model of this paper, it turns out that the information is not fully revealed to uninformed agents, even when the market is in some sense approximately frictionless.

description: A classical construction of Katz gives a purely algebraic construction of Eisenstein–Kronecker series using the Gauß–Manin connection on the universal elliptic curve. This approach gives a systematic way to study algebraic and p-adic properties of real-analytic Eisenstein series. In the first part of this paper we provide an alternative algebraic construction of Eisenstein–Kronecker series via the Poincaré bundle. Building on this, we give in the second part a new conceptional construction of Katz’ two-variable p-adic Eisenstein measure through p-adic theta functions of the Poincaré bundle.

description: This paper analyses the properties of a model of imperfect competition in conjunction with a preference for product variety. When the consumer treats product variety as parametric, a tax scheme is described that generates a socially optimal equilibrium from market behaviour. Welfare-improving and optimal commodity taxes are also discussed. An alternative, conjectural, definition of equilibrium is introduced; for a single consumer model this is argued to result in greater variety and utility. If further consumers are introduced, variety causes externalities in consumption; their effects are analysed and policies to overcome these discussed.

Asteroseismology of evolved stars to constrain the internal transport of angular momentum. III. Using the rotation rates of intermediate-mass stars to test the Fuller-formalism

description: Context: The internal characteristics of stars, such as their core rotation rates, are obtained via asteroseismic observations. A comparison of core rotation rates found in this way with core rotation rates as predicted by stellar evolution models demonstrate a large discrepancy. This means that there must be a process of angular momentum transport missing in the current theory of stellar evolution. A new formalism was recently proposed to fill in for this missing process, which has the Tayler instability as its starting point (hereafter referred to as `Fuller-formalism'). Aims: We investigate the effect of the Fuller-formalism on the internal rotation of stellar models with an initial mass of 2.5 Mo. Methods: Stellar evolution models, including the Fuller-formalism, of intermediate-mass stars were calculated to make a comparison between asteroseismically obtained core rotation rates in the core He burning phase and in the white dwarf phase. Results: Our main results show that models including the Fuller-formalism can match the core rotation rates obtained for the core He burning phases. However, these models are unable to match the rotation rates obtained for white dwarfs. When we exclude the Fuller-formalism at the end of the core He burning phase, the white dwarf rotation rates of the models match the observed rates. Conclusions: We conclude that in the present form, the Fuller-formalism cannot be the sole solution for the missing process of angular momentum transport in intermediate-mass stars.

description: This paper examines the relationship between trade unions and the incidence of share ownership, profit sharing and value added schemes in Britain. The first two schemes are more common in the union sector whilst the third occurs more in non-union establishments. A distinction is made between weak and strong unions and it is found that performance linked pay schemes are in general less likely to be present if an establishment has a strong union rather than a weak one.

Since such Rydberg excitons have strong van der Waals interactions, they can dynamically break the conditions for resonant exciton creation and dramatically modify the refractive index of the material in a nonlinear manner. We explore this mechanism theoretically and determine its effects on the optical properties of a semiconductor for the case of degenerate pair-state asymptotes of Rydberg excitons in Cu$_2$O. Upon analyzing the additional effects of a dilute residual electron-hole plasma, we find quantitative agreement with previous transmission measurements, which provides strong indications for the enhancement of Rydberg-induced nonlinearities by surrounding free charges.

description: The static local-field factor (LFF) of the 2-D electron fluid is calculated {\it nonperturbatively} using a mapping to a classical Coulomb fluid $\lbrack$Phys. Rev. Lett., {\bf 87}, 206$\rbrack$. The LFF for the paramagnetic fluid {\it differs markedly} from perturbation theory where a maximum near 2$k_F$ is expected. Our LFF has a quasi-linear small-k region leading to a maximum close to 3$k_F$, in agreent with currently available quantum Monte Carlo data. The structure in the LFF and its dependence on the density and temperature are interpretted as a signature of correlated scattering of electron pairs of opposite spin.The lack of structure at $2k_F$ implies weakened Friedel oscillations, Kohn anomalies etc.

description: The coordination of Froduction and consumption decisions is analysed in a static model where the interdependence between production, income and demand is explicitly modelled. With imperfect competition and non-convex production technologies it is shown that there exists a zero pure profit equilibrium with a positive level of employment and possible involuntary employment. Finally, it is shown how to arrange a form of external intervention so as to ensure full employment.

The optimal edge for containing the spreading of SIS model

description: Numerous real-world systems, for instance, the communication platforms and transportation systems, can be abstracted into complex networks. Containing spreading dynamics (e.g., epidemic transmission and misinformation propagation) in networked systems is a hot topic in multiple fronts. Most of the previous strategies are based on the immunization of nodes. However, sometimes, these node--based strategies can be impractical. For instance, in the train transportation networks, it is dramatic to isolating train stations for flu prevention. On the contrary, temporarily suspending some connections between stations is more acceptable. Thus, we pay attention to the edge-based containing strategy. In this study, we develop a theoretical framework to find the optimal edge for containing the spreading of the susceptible-infected-susceptible model on complex networks. In specific, by performing a perturbation method to the discrete-Markovian-chain equations of the SIS model, we derive a formula that approximately provides the decremental outbreak size after the deactivation of a certain edge in the network. Then, we determine the optimal edge by simply choosing the one with the largest decremental outbreak size. Note that our proposed theoretical framework incorporates the information of both network structure and spreading dynamics. Finally, we test the performance of our method by extensive numerical simulations. Results demonstrate that our strategy always outperforms other strategies based only on structural properties (degree or edge betweenness centrality). The theoretical framework in this study can be extended to other spreading models and offers inspirations for further investigations on edge-based immunization strategies.

description: This paper reports on a student enterprise carried out under the ambit of the University of British Columbia Food System Project. The Project seeks to initiate a transition towards sustainability in the campus food system and incorporates a process of community-based action research. The authors were requested to assist the Alma Mater Society in carrying out an action plan designed to aid one of its several food outlets to carry a lighter ecological footprint. A literature review and communication with stakeholders provided direction for the project. The objective of this study was to introduce a seasonal, local, vegetarian item into The Pendulum’s menu, the chosen food outlet. Ingredients for the menu item were selected based on their relative abundance and local availability from September to April, the busiest period for The Pendulum. Another consideration was the potential to source food materials from the UBC Farm in the future. A beet and apple salad with goat cheese was prepared, evaluated by a sensory panel, costed, nutritionally analyzed, and then test marketed at The Pendulum. Display case signage was used to market the salad as local, seasonal, nutritional, and that it helps to reduce the ecological footprint of the Alma Mater Society. The salad was popular, selling out within a day, and will be incorporated into The Pendulum menu.

description: Cold inelastic collisions between confined cesium (Cs) atoms and Cs$\_2$ molecules are investigated inside a CO$\_2$ laser dipole trap. Inelastic atom-molecule collisions can be observed and measured with a rate coefficient of $\sim 2.5 \times 10^{-11} $cm$^3$ s$^{-1}$, mainly independent of the molecular ro-vibrational state populated. Lifetimes of purely atomic and molecular samples are essentially limited by rest gas collisions. The pure molecular trap lifetime ranges 0,3-1 s, four times smaller than the atomic one, as is also observed in a pure magnetic trap. We give an estimation of the inelastic molecule-molecule collision rate to be $\sim 10^{-11}$ cm$^{3}$ s$^{-1}$.

description: In this paper we solve for the optimal (Stackelberg) policy in a model of credibility and monetary policy developed by Cuckierman and Meltzer(1486) . Unlike the (Nash) solution provided by Cuckierman and Meltzer the dynamic optimisation problem facing the monetary authority in this case isnot of a linear quadratic form and certainty equivalence does not apply. The learning behaviour of the private sector (regarding the policy maker's preferences ) becomes intimately linked with the choice of the optimal policy and cannot be separated as in the certainty equivalent case. Once the dual effect of the optimal Stackelberg policy is recognised the monetary authority has an additional channel of influence to consider beyond that taken into account by sub—optimal certainty equivalent , Nash, policy rules. Unlike Nash behaviour the Stackelberg solution implies no inflationary bias but it lacks credibility. The learning behaviour of the private sector does not sufficiently inhibit the incentive of the monetary authority to cheat in this model despite the fact that this learning is explicitly recognised in the Stackelberg solution.
