Physical Observables for Noncommutative Landau Levels
Creators: name: Riccardi, Mauro
Publisher: name: arXiv
Year: 2005
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The Quantum Mechanics of a point particle on a Noncommutative Plane in a magnetic field is implemented in the present work as a deformation of the algebra which defines the Landau levels. I show how to define, in this deformed Quantum Mechanics, the physical observables, like the density correlation functions and Green function, on the completely filled ground level. Also it will be shown that the deformation changes the effective magnetic field which acts on the particles at long range, leading to an incompressible fluid with fractional filling of Laughlin type.

Productivity Analysis

description: This paper specifies an empirical model of the relative decline of the agricultural sector consistent with the neoclassical explanation. We utilize a production theory approach to analyze the effect of changes in relative prices, relative factor endowments and technical change on the share of agriculture in GDP in a growing economy. The model is estimated with time series data on the agricultural sector and nonagricultural sectors in Taiwan.
Characterization of the S. cerevisiae Rap1 DNA binding domain and biochemical analysis of its interactions with telomeric and silencer DNA
Creators: name: Stone, Geoffrey
Publisher: name: University of British Columbia
Year: 2009

description: groove. Deletion of this region resulted in a protein able to bind telomere and silencer DNA with high affinity, suggesting that this region is not essential for DNA binding or HTH1-HTH2 cooperative interaction. Deletion of a "loop" region between HTH1 and HTH2 was also performed, and results suggested a role for this region in optimal binding of Rap 1 to tandemly repeated telomere sequences. Rapl is a multifunctional protein in S. cerevisiae. It plays a role in chromatin organization, gene silencing and transcriptional activation. Activation alone takes place using up to 100 Rapl DNA binding sites on the genome. All of these functions are mediated by Rapl binding to the DNA duplex, and the Rapl DBD structure must be adaptive to the requirements of the various cellular processes. This thesis suggests that the HTH1, HTH2, "tail" and "loop" regions are specifically designed to optimize Rapl function. Cooperative binding to DNA by HTH1-HTH2 allows a certain degree of degeneracy at high affinity binding sites. "Tail" interactions, while not essential for DNA binding, maintain binding site specificity at a "core" ACC sequence. Finally, the "loop" region allows proper alignment of HTH1 and HTH2, increasing the cooperative association of these two motifs.

description: We propose and experimentally demonstrate a plug-and-play, practical, and enabling method allowing to synchronize the building blocks of a quantum network in an all-optical way. Our scheme relies on mature and reliable classical telecommunication and non-linear optical technologies and can be implemented in a universal way with off-the-shelf components. Compared to already reported solutions, it allows achieving high-quality synchronization compatible with high network-operation rate and is free from opto-electronic jitters affecting servo-loop based configurations. We test our scheme with a genuine quantum optical method in terms of the interference between two photons coming from two remotely synchronized sources spaced by distances of up to 100 km. Measured visibilities well above 90% confirm the validity of our approach. Due its simplicity and high-quality performance, our scheme paves the way for the synchronization of long-distance quantum networks based on fibre, free-space, as well as hybrid solutions.

On the diffusive anomalies in a long-range Hamiltonian system
Creators: name: Moyano, Luis G.

Year: 2006
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: We scrutinize the anomalies in diffusion observed in an extended long-range system of classical rotors, the HMF model. Under suitable preparation, the system falls into long-lived quasi-stationary states presenting super-diffusion of rotor phases. We investigate the diffusive motion of phases by monitoring the evolution of their probability density function for large system sizes. These densities are shown to be of the $q$-Gaussian form, $P(x)\propto (1+(q-1)[x/β]^2)^{1/(1-q)}$, with parameter $q$ increasing with time before reaching a steady value $q\simeq 3/2$. From this perspective, we also discuss the relaxation to equilibrium and show that diffusive motion in quasi-stationary trajectories strongly depends on system size.

description: We show that a simple approximation based on concepts underlying the Kibble-Zurek theory of second order phase transition dynamics can be used to treat avoided level crossing problems. The approach discussed in this paper provides an intuitive insight into quantum dynamics of two level systems, and may serve as a link between the theory of dynamics of classical and quantum phase transitions. To illustrate these ideas we analyze dynamics of a paramagnet-ferromagnet quantum phase transition in the Ising model. We also present exact unpublished solutions of the Landau-Zener like problems.

Molecular collapse in graphene: sublattice symmetry effect

description: Atomic collapse can be observed in graphene because of its large "effective" fine structure constant, which enables this phenomenon to occur for an impurity charge as low as $Z_c\sim 1-2$. Here, we investigate the effect of the sublattice symmetry on molecular collapse in two spatially separated charge tunable vacancies, that are located on the same (A-A type) or different (A-B type) sublattices. We find that the broken sublattice symmetry: (1) does not affect the location of the main bonding and anti-bonding molecular collapse peaks, (2) but shifts the position of the satellite peaks, because they are a consequence of the breaking of the local sublattice symmetry, and (3) there are vacancy characteristic collapse peaks that only occur for A-B type vacancies, which can be employed to distinguish them experimentally from the A-A type. As the charge, energy, and separation distance increase, the additional collapse features merge with the main molecular collapse peaks. We show that the spatial distribution around the vacancy site of the collapse states allows us to differentiate the molecular from the frustrated collapse.

description: The paper demonstrates a group incentive program to encourage farmer adoption of best management practices. It is demonstrated that the best management practices may not actually reduce farm profits but may increase farm profits and reduce environmental pollution. This may bring about a win-win situation for sponsor, the farmer participating in the program, and the society as a whole. The results show that the farmers subjective beliefs about response of corn yields and profits to nitrogen application differ from the simulated responses which in turn results in the willingness-to-Accept for adoption best management practices significantly higher than the expected program payments. The program could be implemented as an educational effort to demonstrate the benefits of sound management practices for larger adoption in the long run.

Entropy stable discontinuous Galerkin methods for ten-moment Gaussian closure equations

Publisher: name: arXiv
Year: 2020
Subjects: subject: Numerical Analysis (math.NA)

description: In this article, we propose high order discontinuous Galerkin entropy stable schemes for ten-moment Gaussian closure equations, which is based on the suitable quadrature rules (see [8]). The key components of the proposed method are the use of an entropy conservative numerical flux [31] in each cell and a suitable entropy stable numerical flux at the cell edges. This is then used in the entropy stable DG framework of [8] to obtain entropy stability of the semi-discrete scheme. We also extend these schemes to a source term that models plasma laser interaction. For the time discretization, we use strong stability preserving schemes. The proposed schemes are then tested on several test cases to demonstrate stability, accuracy, and robustness.

Strangeness production and hypernuclear formation in proton and antiproton induced reactions
Creators: name: Feng, Zhao-Qing
Publisher: name: arXiv
Year: 2020
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Strange particles and hyperfragments in collisions of antiprotons and protons on nuclei have been investigated systematically within a microscopic transport model. The hyperons are produced from the annihilation in antibaryon-baryon collisions and strangeness exchange process in antiproton induced reactions. A coalescence approach is used for constructing the primary hyperfragments in phase space and the statistical model is modified for describing the decay of hyperfragments via evaporating hyperon, neutron, charged particles etc, in which the shell effect, binding energy and root-mean-square radii are taken into account. It is found that the influence of the hyperon-nucleon interaction on the free $Λ$ and $Ξ^{-}$ production is negligible. However, the large hyperfragment yields are obvious with the attractive potential. The production of double strangeness hyperfragments are reduced below 1$μb$ in comparison to the yields of $Λ$-hyperfragments with the cross sections of 0.05-0.1 mb in the antiproton induced reactions on $^{63}$Cu at the incident momenta of 1-5 GeV/c. The light hyperfragments are formed in the dynamical fragmentation process. The energy dependence of hyperfragment formation is weak once the incident energy above the threshold energy for the hyperon production.

description: Arguments about using computer facilities to classroom teaching have gained a lot of attention over time. Using the computer facilities will be helpful to demonstrate real world applications, while poor data or inappropriate case studies might reduce the confidence in applying computer programs in classroom teaching. In this article we examine the results of using computer facilities to teach Business statistics to a group of Management students sampled from Krannert School of Management, Purdue University. This study shows that students are attracted to the interactive computer programs designed for the Business Statistics course, and students are more motivated to attend classes when using computer facilities are applied in teaching. Furthermore, computer programs help students to understand confusing topics (such as the Central Limit Theorem), and students feel that teaching them to use computer facilities really improves students' ability to apply similar programs in analyzing real world problems.

description: Dynamic programming is used to examine whether Australia should store wheat for subsequent sale at higher prices. The dynamic programming model is developed assuming that the demand for Australian wheat is perfectly elastic at the world price. An important consequence of this assumption is that the algorithm used in computing the optimal policy takes a very simple form. It is concluded that interest rate and wheat price in the following season are the major determinants of storage policy. When prices are stable, rule-of-thumb policies, such as storing when prices are below average, are sub-optimal.

description: About 5% of upper main sequence stars are permeated by a strong magnetic field, the origin of which is still matter of debate. With this work we provide observational material to study how magnetic fields change with the evolution of stars on the main sequence, and to constrain theory explaining the presence of magnetic fields in A and B-type stars. Using FORS1 in spectropolarimetric mode at the ESO VLT, we have carried out a survey of magnetic fields in early-type stars belonging to open clusters and associations of various ages. We have measured the magnetic field of 235 early-type stars with a typical uncertainty of about 100 G. In our sample, 97 stars are Ap or Bp stars. For these targets, the median error bar of our field measurements was about 80 G. A field has been detected in about 41 of these stars, 37 of which were not previously known as magnetic stars. For the 138 normal A and B-type stars, the median error bar was 136 G, and no field was detected in any of them.

description: We investigate theoretically the effect of a finite electric field on the resistivity of a disordered one-dimensional system in the variable-range hopping regime. We find that at low fields the transport is inhibited by rare fluctuations in the random distribution of localized states that create high-resistance ``breaks'' in the hopping network. As the field increases, the breaks become less resistive. In strong fields the breaks are overrun and the electron distribution function is driven far from equilibrum. The logarithm of the resistance initially shows a simple exponential drop with the field, followed by a logarithmic dependence, and finally, by an inverse square-root law.

Year: 1978
Subjects: Land Economics/Use

description: Changing social objectives and a greater variety of policy instruments require extra detail and fuller specification in analyses of land policies. Consumer's surplus remains an appropriate measure of net social benefit but surplus values must be estimated more carefully. The paper examines the application of four surplus concepts to policy problems and illustrates a methodology to estimate all four. The estimates for the different concepts can differ widely and the correct concepts have not always been advocated. The methodology appears useful where other estimation procedures have failed.
The Cohomology Algebra of the Semi-infinite Weil Complex

Subjects: subject: Quantum Algebra (math.QA)

description: In 1993, Lian-Zuckerman constructed two cohomology operations on the BRST complex of a conformal vertex algebra with central charge 26. They gave explicit generators and relations for the cohomology algebra equipped with these operations in the case of the c=1 model. In this paper, we describe another such example, namely, the semi-infinite Weil complex of the Virasoro algebra. The semi-infinite Weil complex of a tame Z-graded Lie algebra was defined in 1991 by Feigin-Frenkel, and they computed the linear structure of its cohomology in the case of the Virasoro algebra. We build on this result by giving an explicit generator for each non-zero cohomology class, and describing all algebraic relations in the sense of Lian-Zuckerman, among these generators.

description: One of the very common in situ signatures of interplanetary coronal mass ejections (ICMEs), as well as other interplanetary transients, are Forbush decreases (FDs), i.e. short-term reductions in the galactic cosmic ray (GCR) flux. A two-step FD is often regarded as a textbook example, which presumably owes its specific morphology to the fact that the measuring instrument passed through the ICME head-on, encountering first the shock front (if developed), then the sheath and finally the CME magnetic structure. The interaction of GCRs and the shock/sheath region, as well as the CME magnetic structure, occurs all the way from Sun to Earth, therefore, FDs are expected to reflect the evolutionary properties of CMEs and their sheaths. We apply modelling to different ICME regions in order to obtain a generic two-step FD profile, which qualitatively agrees with our current observation-based understanding of FDs. We next adapt the models for energy dependence to enable comparison with different GCR measurement instruments (as they measure in different particle energy ranges). We test these modelling efforts against a set of multi-spacecraft observations of the same event, using the Forbush decrease model for the expanding flux rope (ForbMod). We find a reasonable agreement of the ForbMod model for the GCR depression in the CME magnetic structure with multi-spacecraft measurements, indicating that modelled FDs reflect well the CME evolution.

These solitons cannot travel parallel to the noncommutative spatial direction. For the U(1) case, the rank-one single-soliton configuration is constructed explicitly and is singular in the commutative limit. The projection to 1+1 dimensions reduces it to a noncommutative instanton-like configuration. The latter is governed by a new integrable equation, which describes a Moyal-deformed sigma model with a particular Euclidean metric and a magnetic field.

The influence of red alder in adjacent conifer stands : nutrient cycling and light transmission
Creators: name: Lavery, John Meredith
Publisher: name: University of British Columbia
Year: 2009

description: Red alder (Alnus rubra(Bong.)) is an important successional deciduous species in British Columbia with expanding commercial markets. Alder is a pioneer species which grows rapidly on disturbed sites and in riparian areas of coastal British Columbia. Alder's impressive early height growth and ability to increase the rate of cycling of nitrogen and other nutrients lead to a challenge in managing alder with conifers. Managing alder in mixedwood stands requires finding an appropriate balance between competition for light and the improvement in N status of a site, which would lead to improved conifer growth over time. Light transmission to the understory of adjacent alder and conifer stands was measured along a transect between the two stands using photodiode and quantum sensors, as well as hemispherical photography. Light varied with age and site, but alder stands generally had more light in the understory than the adjacent conifer stands. This difference was more marked in younger stands. Modeling using SLIM and LITE correlated well with the sensor information, and further modelling of the alder stands suggests that the amount of light available to conifers adjacent to an alder stand is of adequate quantity to sustain conifer growth within 5m of the alder/conifer stand boundary. The assessment of nutrient cycling in alder stands involved independent studies of litterfall, soil qualities, and a bioassay of the soils using Douglas-fir seedlings. Higher concentrations of N and several other nutrients were found in alder litter, but the conifer litter had very high levels of several micronutrients. The alder litterfall made significant contributions to nutrient inputs up to 15m into the conifer stands. The soil showed elevated N, and Total C, C:N and pH were influenced by alder presence in the oldest stands. This series of experiments also showed the influence of alder on the concentration of N in the shoots of the seedlings, as well as an influence on boron. The influence of alder litterfall, soil and bioassay N at points along the transects was correlated at the oldest and middle aged sites, suggesting that red alder produces a significant change in the nutrient cycling in adjacent conifer stands. Implications for managers and suggestions for management are discussed.

description: Based on the 1990-2010 CTPP data in Baton Rouge, this research analyzes the temporal trends of commuting patterns in both time and distance. In comparison to previous work, commuting length is calibrated more accurately by Monte Carlo based simulation of individual journey-to-work trips to mitigate the zonal effect. First, average commute distance kept climbing in 1990-2010 while average commute time increased in 1990-2000 but then slightly dropped toward 2010. Secondly, urban land use remained a good predictor of commuting pattern over time (e.g., explaining up to 90% of mean commute distance and about 30% of mean commute time). Finally, the percentage of excess commuting increased significantly in 1990-2000 and stabilized afterwards.
THE CASE AGAINST TARIFF COMPENSATION

Subjects: Political Economy

description: Should lightly protected industries be given tariff compensation? Reasonable people can and do differ on this issue; neither the case supporting tariff compensation nor that opposing it is fully conclusive. Nevertheless, it is the purpose of this paper to argue that, on balance, the stronger argument is on the negative side. It is argued that economists in particular should focus their limited influence on recommending tariff reductions rather than tariff compensation, but that even if this fails they should be most reluctant to recommend tariff compensation. The potential benefits from tariff compensation are small relative to the gains from tariff reduction but the informational problems of tariff compensation are such as to make even these small potential benefits unlikely in practice.

description: In a paper in the April 1977 issue of this Journal by Scobie and Franklin (1977) it is argued that supervised credit programs are of dubious value in promoting technological change in developing agriculture. However, the case presented by the authors is not conclusive and may be open to alternative interpretations because: (a) the general economic framework used by them is inappropriate for use in smallholder developing agriculture; (b) the results of the Guatemalan test case are inconclusive; and ( c) these results can be plausibly explained in other ways in any case.
Compact Radio Emission from Nearby Galaxies with Mid-infrared Nuclear Outbursts

description: We present 5.5 GHz observations with the VLA of a sample of nearby galaxies with energetic nuclear outbursts at mid-infrared (MIR) bands. These observations reach a uniform depth down to a median rms of ~10 uJy, representing one of most sensitive searches for radio emission associated with nuclear transients. We detect radio emission in 12 out of 16 galaxies at a level of >5sigma, corresponding to a detection rate of 75%. Such a high detection is remarkably different from previous similar searches in stellar tidal disruption events. The radio emission is compact and not resolved for the majority of sources on scales of ~<0.5" (<0.9 kpc at z<0.1). We find the possibility of the star-formation contributing to the radio emission is low, but an AGN origin remains a plausible scenario, especially for sources that show evidence of AGN activity in their optical spectra. If the detections could represent radio emission associated with nuclear transient phenomenon such as jet or outflow, we use the blast wave model by analogy with the GRB afterglows to describe the evolution of radio light curves. In this context, the observations are consistent with a decelerating jet with an energy of ~10^{51-52} erg viewed at 30\degree-60\degree off-axis at later times, suggesting that powerful jets may be ubiquitous among MIR-burst galaxies. Future continuous monitoring observations will be crucial to decipher the origin of radio emission through detections of potential flux and spectral evolution. Our results highlight the importance of radio observations to constrain the nature of nuclear MIR outbursts in galaxies.

description: We present HARPS spectroscopy of mu Arae (HD160691) performed for studying the origin of the metallicity excess in this planet-hosting stars. The asteroseismologic campaign led to the previously reported discovery of a 14 earth mass planetary companion (Santos et al. 2004). The present analysis reinforces this interpretation by excluding other possible processes for explaining the observed Doppler variation and leads to the identification of up to 43 p-mode oscillations with l=0-3, frequencies in the range 1.3-2.5 mHz and amplitudes in the range 10-40 cm/s.
ON WHY RATES OF ASSISTANCE DIFFER BETWEEN AUSTRALIA'S RURAL INDUSTRIES

Year: 1978
Subjects: Community/Rural/Urban Development

description: An economic theory of politics is applied to the question of why there are large differences in effective rates of assistance to Australia's rural industries. It is suggested that a major part of the explanation is the different incentives faced by industry lobby groups to demand assistance and by the government to supply assistance. Various determinants of the incentives to demand and supply assistance are hypothesized, and these hypotheses are tested against the existing pattern of rural assistance. The evidence generally supports the hypotheses, and suggests some policy changes to reduce existing government distortions.
DECOMPOSING THE VARIANCE OF GROSS REVENUE INTO DEMAND AND SUPPLY COMPONENTS

Subjects: Demand and Price Analysis

description: Some recent analyses relating to gross revenue instability have used a procedure for decomposing the variance of gross revenue into components attributable to price variability, quantity variability and interaction between these. This paper offers some criticisms of the procedure and outlines an alternative procedure which divides the variance of gross revenue into components due to demand variability, supply variability and interaction between these. The procedure is used to investigate the causes of instability in quarterly beef revenues in the Australian beef industry. Since demand and supply variability are both important contributors to beef revenue instability, direct market intervention to stabilise beef industry revenues would be a complex and risky task.

description: Within the dinuclear system model, unknown neutron-deficient isotopes Np, Pu, Am, Cm, Bk, Cf, Es, Fm are investigated in $^{40}$Ca, $^{36,40}$Ar, $^{32}$S, $^{28}$Si,$^{24}$Mg induced fusion-evaporation reactions and multinucleon transfer reactions with radioactive beams $^{59}$Cu,$^{69}$As,$^{90}$Nb,$^{91}$Tc, $^{94}$Rh, $^{105,110}$Sn, $^{118}$Xe induced with $^{238}$U near Coulomb barrier energies. The production cross sections of compound nuclei in the fusion-evaporation reactions and fragments yields in the multinucleon transfer reactions are calculated within the model. A statistical approach is used to evaluate the survival probability of excited nuclei via the both reaction mechanisms. A dynamical deformation is implemented into the model in the dissipation process. It is found that charge particle channels (alpha and proton) dominate in the decay process of proton-rich nuclides and the fusion-evaporation reactions are favorable to produce the new neutron-deficient actinide isotopes. The total kinetic energies and angular spectra of primary fragments are strongly dependent on colliding orientations.

Two-matrix model with semiclassical potentials and extended Whitham hierarchy

description: We consider the two-matrix model with potentials whose derivative are arbitrary rational function of fixed pole structure and the support of the spectra of the matrices are union of intervals (hard-edges). We derive an explicit formula for the planar limit of the free energy and we derive a calculus which allows to compute derivatives of arbitrarily high order by extending classical Rauch's variational formulae. The four-points correlation functions are explicitly worked out. The formalism extends naturally to the computation of residue formulae for the tau function of the so-called universal Whitham hierarchy studied mainly by I. Krichever: our setting extends that moduli space in that there are certain extra data.

PROS AND CONS OF TEMPORARY INDUSTRY ASSISTANCE

Year: 1978
Subjects: Political Economy

description: The objectives and relative effectiveness of different methods of providing temporary assistance to a particular industry experiencing a significant reduction in returns and liquidity are evaluated. It is doubtful that assistance can be justified for resource efficiency reasons. This is argued to be so when the cause of the downturn in industry returns is due to temporary factors, such as drought, and when it is due to long-term trend factors, such as economic growth. While an industry slump can cause welfare problems, most households are able to use contingency strategies, e.g. savings, or resort to existing welfare programs, e.g. unemployment benefits. Direct income grants are preferable to output and input subsidies as means of providing welfare assistance.
