Year: 2005

description: We investigate the three-point functions of the weak lensing cosmic shear, using both analytic methods and numerical results from N-body simulations. The analytic model, an isolated dark matter halo with a powerlaw profile chosen to fit the effective index at the scale probed, can be used to understand the basic properties of the eight three-point functions observed in simulations. We use this model to construct a single three-point function estimator that "optimally" combines the eight three-point functions. This new estimator is an alternative to Map statistics and provides up to a factor of two improvement in signal to noise compared to previously used combinations of cosmic shear three-point functions.

description: This paper studies how the strength of intellectual property rights (IPRs) affects investments in biological innovations when the value of an innovation is stochastically reduced to zero because of the evolution of pest resistance. We frame the problem as a research and development (R&D) investment game in a duopoly model of sequential innovation. We characterize the incentives to invest in R&D under two competing IPR regimes, which differ in their treatment of the follow-on innovations that become necessary because of pest adaptation. Depending on the magnitude of the R&D cost, ex ante firms might prefer an intellectual property regime with or without a "research exemption" provision. The study of the welfare function that also accounts for benefit spillovers to consumers-which is possible analytically under some parametric conditions, and numerically otherwise-shows that the ranking of the two IPR regimes depends critically on the extent of the R&D cost.

description: It is shown that by properly designing the spatial dependence of the nonlinearity it is possible to induce long-living Bloch oscillations of a localized wavepacket in a periodic potential. The results are supported both by analytical and numerical investigations and are interpreted in terms of matter wave dynamics displaying dozens of oscillation periods without any visible distortion of the wave packet.

description: Accurate atmospheric parameters and chemical composition of planet-hosting stars are crucial for characterising exoplanets and understanding their formation and evolution. Our objective is to uniformly determine the atmospheric parameters and chemical abundances of carbon, nitrogen, oxygen, and the $α$-elements, magnesium and silicon, along with C/O, N/O and Mg/Si abundance ratios in planet-hosts. We aim to investigate the potential links between stellar chemistry and the presence of planets using high-resolution spectra of 149 F, G, and K dwarf and giant stars hosting planets or planetary systems. The spectra were obtained with the Vilnius University Echelle Spectrograph on the 1.65 m Molėtai Observatory telescope. Stellar parameters were determined through standard analysis using equivalent widths and one-dimensional, plane-parallel model atmospheres calculated under the assumption of local thermodynamical equilibrium. The differential synthetic spectrum method was used to uniformly determine carbon C(C2), nitrogen N(CN), oxygen [O I], magnesium Mg I, and silicon Si I elemental abundances as well as the C/O, N/O, and Mg/Si ratios. We found that [C/Fe], [O/Fe], and [Mg/Fe] are lower in metal-rich dwarf hosts; whereas [N/Fe] is close to the Solar ratio. Giants show smaller scatter in [C/Fe] and [O/Fe] and lower than the Solar average [C/Fe] and C/O ratios. The (C+N+O) abundances increase with [Fe/H] in giant stars, with a minimal scatter. We also noted an overabundance of Mg and Si in planet hosting stars, particularly at lower metallicities, and a lower Mg/Si ratio in stars with planets. In giants hosting high-mass planets, nitrogen shows a moderate positive relationship with planet mass. C/O and N/O ratios show moderate negative and positive slopes in giant stars, respectively. The Mg/Si ratio shows a negative correlation with planet mass across the entire stellar sample.

description: We show that conditional photon detection induces instantaneous phase synchronization between two decoupled quantum limit-cycle oscillators. We consider two quantum van der Pol oscillators without mutual coupling, each with an additional linearly coupled bath, and perform continuous measurement of photon counting on the output fields of the two baths interacting through a beam splitter. It is observed that in-phase or anti-phase coherence of the two decoupled oscillators instantaneously increases after the photon detection and then decreases gradually in the weak quantum regime or quickly in the strong quantum regime until the next photon detection occurs. In the strong quantum regime, quantum entanglement also increases after the photon detection and quickly disappears. We derive the analytical upper bounds for the increases in the quantum entanglement and phase coherence by the conditional photon detection in the quantum limit.

description: For $f,g\inω\ho$ let $\mycfa_{f,g}$ be the minimal number of uniform $g$-splitting trees needed to cover the uniform $f$-splitting tree, i.e. for every branch $ν$ of the $f$-tree, one of the $g$-trees contains $ν$. $\myc_{f,g}$ is the dual notion: For every branch $ν$, one of the $g$-trees guesses $ν(m)$ infinitely often. It is consistent that $\myc_{f_ε,g_ε}=\mycfa_{f_ε,g_ε}=κ_ε$ for $\al1$ many pairwise different cardinals $κ_ε$ and suitable pairs $(f_ε,g_ε)$. For the proof we use creatures with sufficient bigness and halving. We show that the lim-inf creature forcing satisfies fusion and pure decision. We introduce decisiveness and use it to construct a variant of the countable support iteration of such forcings, which still satisfies fusion and pure decision.

description: This paper develops an analytical framework which structures the problem of whether, how and to what extent small producers in developing countries are disadvantaged by the increasing prevalence of food quality standards. Based on a literature review, the empirical evidence is structured and research gaps are identified. The paper finds that small and medium producers rarely comply without support from downstream actors. In case of well-educated and relatively wealthy farmers, forward integration is also found. No empirical support exists for the intuitively appealing hypothesis of a lower cost of compliance per unit of output for large producers. Zusammenfassung In diesem Papier wird ein Analyserahmen entwickelt, um die Möglichkeit und das Ausmaß der Benachteiligung von Kleinlandwirten in Entwicklungsländern durch die zunehmende Verbreitung von Qualitätsstandards für Produkte der Agrar- und Ernährungsindustrie zu strukturieren. In einer Literaturübersicht werden die Ergebnisse empirischer Studien ausgewertet und Forschungslücken identifiziert. Es wird gezeigt, dass Kleinlandwirte aufwändige Prozessstandards selten ohne die Unterstützung von Unternehmen auf nachgelagerten Stufen der Wertschöpfungskette implementieren. Die einleuchtende und weit verbreitete Hypothese, dass die Cost of Compliance per Produkteinheit für große Produzenten niedriger als für kleine Produzenten seien, wurde bisher empirisch nicht bestätigt.
Identified particle correlation studies in central Au + Au collisions at sqrt(S)= 200 GeV

description: We present correlations between strange baryons and mesons with charged hadrons in AuAu and pp collisions at sqrt(s)=200 GeV for different pT ranges and centralities. We observe that for central AuAu collisions, the large width of the back side correlations indicates a collapse of the jet structure. This is consistent with previous measurement of suppression of the back side correlation for unidentified charged hadrons. However, in the medium pT range the same side correlations show large AA/pp ratios and wek centrality dependencies which indicate different medium modification of the soft jet components. For different leading particle species we have found no significant difference for both same side and back side correlations. These results are comparable to PHENIX's measurements in similar pT range

A markov decision process model for airline meal provisioning
Creators: name: Goto, Jason Hidekazu
Publisher: name: University of British Columbia
Year: 2009

description: An airline caterer seeks to provide a meal quantity for each flight that closely matches final on-board passenger load. Faced with preparation lead-time, the caterer must estimate required meal quantities well in advance of departure. Passenger load may vary considerably during this lead-time, thus, adjustments are often required as more information becomes available. In this thesis, we model the meal ordering processes at Canadian Airlines as a finite-horizon Markov decision process. The model generates policies that show the caterer how to adjust meal quantities at each decision point to minimize ordering costs. We evaluate the performance achieved with the optimal policies by applying them to a holdout dataset, and compare the results to those observed in actual practice. Next, we use the model to observe the multi-objective problem of excess meal provisioning and short meal provisioning, and estimate the cost of achieving high service levels. This thesis finds that current practice in meal ordering at Canadian Airlines often achieves performance close to that achieved with the minimum cost policies. Application of the model to a group of 40 flights yielded estimated savings of $4,500 per month, while reducing the number of short catered flights by 42%.
Complexity of Networks

description: Network or graph structures are ubiquitous in the study of complex systems. Often, we are interested in complexity trends of these system as it evolves under some dynamic. An example might be looking at the complexity of a food web as species enter an ecosystem via migration or speciation, and leave via extinction. In this paper, a complexity measure of networks is proposed based on the {\em complexity is information content} paradigm. To apply this paradigm to any object, one must fix two things: a representation language, in which strings of symbols from some alphabet describe, or stand for the objects being considered; and a means of determining when two such descriptions refer to the same object. With these two things set, the information content of an object can be computed in principle from the number of equivalent descriptions describing a particular object. I propose a simple representation language for undirected graphs that can be encoded as a bitstring, and equivalence is a topological equivalence. I also present an algorithm for computing the complexity of an arbitrary undirected network.

Inconsistent Objectives of Agricultural Export Credit Disciplines

Publisher: name: Unknown
Year: 2007
Subjects: International Relations/Trade

description: Negotiated disciplines on export credits in agriculture are intended to (1) eliminate any subsidy element caused by preferential financing or low fees and (2) provide special and differential treatment for developing countries. Inconsistent foundations of these two objectives limit the potential for negotiations on the disciplines to succeed. The subsidy element cannot be eliminated without agreement on the benchmark. Eliminating all advantage relative to private institutions precludes any reason to continue government support. Favourable financing to developing countries would introduce a prohibited subsidy. In their capacity to provide special and differential treatment, export credits fall well short of the requirements for food aid.

Besides employing the standard thermodynamic approach, we investigate the black hole thermodynamics by studying its thermodynamic geometry. We compute the Weinhold and Ruppeiner metrics and compare the thermodynamic geometry with the standard description on the black hole thermodynamics. We further consider the cosmological constant as an additional extensive thermodynamic variable. In the thermodynamic equilibrium three dimensional space, we compute the efficiency of the heat engine and show that it is possible to be built with this black hole.

description: We present BIMA 3 mm observations of the radio continuum source and the molecular gas disk in the radio loud Fanaroff & Riley Type I (FR I)galaxy NGC3801.We have detected a continuum source in the nucleus and determined that it has a flat millimeter-wave spectrum, suggesting that the emission is non-thermal and due to an AGN; the radio core is not evident in existing VLA observations. We also map the extended 3 mm emission from the previously known radio jets. In addition, we detect CO (1--0) emission associated with the dust disk observed in previous HST images. A velocity gradient is observed, indicating a two kpc radius rotating gas ring or disk oriented roughly perpendicular to the radio jets. The inferred molecular gas mass of the disk is $M(H_{2})=3\times10^{8}M_{\odot}$, about 1% of the dynamical mass. We also find a $\sim 10^8$ M$_\odot$ molecular gas clump not associated with the gas disk. There is evidence that this gas is associated with a merger and is infalling. This suggests that FR I type activity is related to merger activity, as is thought to be the case for FR II type radio galaxies. We also find indications that one of the radio jets is entraining gas from the infalling molecular gas.

description: In non-central high energy heavy ion collisions the colliding system posses a huge orbital angular momentum in the direction opposite to the normal of the reaction plane. Due to the spin-orbit coupling in strong interaction, such huge orbital angular momentum leads to the polarization of quarks and anti-quarks in the same direction. This effect, known as the global polarization effect, has been recently observed by STAR Collaboration at RHIC that confirms the theoretical prediction made more than ten years ago. The discovery has attracted much attention on the study of spin effects in heavy ion collision. It opens a new window to study properties of QGP and a new direction in high energy heavy ion physics -- Spin Physics in Heavy Ion Collisions. In this chapter, we review the original ideas and calculations that lead to the predictions. We emphasize the role played by spin-orbit coupling in high energy spin physics and discuss the new opportunities and challenges in this connection.

description: In this paper, we study the quantum decoherence induced by accumulation of electron tunnelings during the quantum measurement of a charge qubit. The charge qubit is a single electron confined in coupled quantum dots. The measurement of the qubit states is performed using a quantum point contact. A set of master equations for qubit states is derived within a nonequilibrium perturbation to the equilibrium reservoir due to the electron accumulation between the source and drain of the quantum point contact. The quantum decoherence of the qubit states arose from the electron accumulation during the measurement is explored in this framework, and several interesting results on charge qubit decoherence are obtained.

description: We show that in extremely irradiated atmospheres of hot super-Earths shortwave absorption of CN can cause strong temperature inversions. We base this study on previous observations of 55 Cancri e, which lead us to believe that ultra-short-period super-Earths can sustain volatile atmospheres, rich in nitrogen and/or carbon. We compute our model atmospheres in a radiative-convective equilibrium for a variety of nitrogen-rich cases and orbital parameters. We demonstrate the effects caused by thermal inversions on the chemistry and compute low resolution synthetic emission spectra for a range of 0.5 - 28 micron. Our results indicate that dueto shortwave absorption of CN, atmospheres with temperatures above 2000 K and C/O $\geq$ 1.0 are prone to thermal inversions. CN is one of the few molecules that is extremely stable at large temperatures occurring on the day side of short period super-Earths. The emission spectrum of such atmospheres will differ substantially from non-inverted cases. In the case of inversions, absorption features become inverted, showing higher than expected flux. We propose that inversions in hot atmospheres should be the expected norm. Hot super-Earths are some of the most extreme natural laboratories for testing predictions of atmospheric chemistry and structure. They are frequently occurring, bright in emission and have short orbital periods. All these factors make them perfect candidates to be observed with JWST and ARIEL missions.

description: We report the results for nucleon decay searches via modes favored by supersymmetric grand unified models in Super-Kamiokande. Using 1489 days of full Super-Kamiokande-I data, we searched for $p \to \barν K^+$, $n \to \barν K^0$, $p \to μ^+ K^0$ and $p \to e^+ K^0$ modes. We found no evidence for nucleon decay in any of these modes. We set lower limits of partial nucleon lifetime 2.3$\times10^{33}$, 1.3$\times10^{32}$, 1.3$\times10^{33}$ and 1.0$\times10^{33}$ years at 90% confidence level for $p \to \barν K^+$, $n \to \barν K^0$, $p \to μ^+ K^0$ and $p \to e^+ K^0$ modes, respectively. These results give a strong constraint on supersymmetric grand unification models.

Theoretical models of segregation variance in the F2 populations and their application in Douglas-fir
Creators: name: Zhi, Jiwei
Publisher: name: University of British Columbia
Year: 2009

description: It is well known that when two pure lines or divergent populations are crossed, an outbreak of variation can be seen in the F₂ populations, caused by the segregating of alleles. Statistical models and qualitative analyses of these models can give insight into the most important mechanisms at work in this mating system. Lande (1981) showed that Wright-Castle method for segregation variance in F₂ populations also applies to parental populations still segregating for the loci of interest. This raises the question as to how divergent must the two parental populations be before the genetic variance in F₂ population is larger than those of parental populations. In this thesis I begin with formulating a genetic model to describe this problem by using the approach of "one locus model" and give a solution to this problem. I then develop two more practical models where the divergence of the two parental populations are maintained by selection- migration balances. I analyze the effects of selection, and migration on the amount of segregation variance in F₂ population. I also consider this problem at the phenotype level without invoking any genetic mechanism. I develop a phenotype transmission model to analyze this problem. Two other models relating to population structure, and sampling problem of this mating system are also developed. A Douglas - fir provenance experiment used is to verify some aspects of the above models.

description: Recently, Zakharov et al. (2005) considered the possibility of evaluating the spin parameter and the inclination angle for Kerr black holes in nearby galactic centers by using future advanced astrometrical instruments. A similar approach which uses the characteristic properties of gravitational retro-lensing images can be followed to measure the charge of Reissner-Nordstrom black hole. Indeed, in spite of the fact that their formation might be problematic, charged black holes are objects of intensive investigations. From the theoretical point of view it is well-known that a black hole is described by only three parameters, namely, its mass M, angular momentum J and charge Q. Therefore, it would be important to have a method for measuring all these parameters, preferably by model independent way. In this paper, we propose a procedure to measure the black hole charge by using the size of the retro-lensing images that can be revealed by future astrometrical missions. A discussion of the Kerr-Newmann black hole case is also offered.

description: Event-triggered control (ETC) holds the potential to significantly improve the efficiency of wireless networked control systems. Unfortunately, its real-world impact has hitherto been hampered by the lack of a network stack able to transfer its benefits from theory to practice specifically by supporting the latency and reliability requirements of the aperiodic communication ETC induces. This is precisely the contribution of this paper. Our Wireless Control Bus (WCB) exploits carefully orchestrated network-wide floods of concurrent transmissions to minimize overhead during quiescent, steady-state periods, and ensures timely and reliable collection of sensor readings and dissemination of actuation commands when an ETC triggering condition is violated. Using a cyber-physical testbed emulating a water distribution system controlled over a real-world multi-hop wireless network, we show that ETC over WCB achieves the same quality of periodic control at a fraction of the energy costs, therefore unleashing and concretely demonstrating its full potential for the first time.

description: The well-known increase of the decoherence rate with the temperature, for a quantum system coupled to a linear thermal bath, holds no longer for a different bath dynamics. This is shown by means of a simple classical non-linear bath, as well as a quantum spin-boson model. The anomalous effect is due to the temperature dependence of the bath spectral profile. The decoherence reduction via the temperature increase can be relevant for the design of quantum computers.

description: We study convective motions taken from hydrodynamic simulations of rotating proto--neutron stars (PNSs) with respect to their ability to excite a dynamo instability which may be responsible for the giant neutron star magnetic fields. Since it is impossible to simulate the magnetic field evolution employing the actual magnetic Reynolds numbers ($\Rm$) resulting from the hydrodynamic simulations, (smallest) critical $\Rm$s and the corresponding field geometries are derived on the kinematic level by rescaling the velocity amplitudes. It turns out that the actual values of $\Rm$ are by many orders of magnitude larger than the critical values found. A dynamo might therefore start to act vigorously very soon after the onset of convection. But as in general dynamo growth rates are non--monotonous functions of $\Rm$ the later fate of the magnetic field is uncertain. Hence, no reliable statements on the existence and efficiency of PNS dynamos can be drawn without considering the interplay of magnetic field and convection from the beginning. Likewise, in so far as convection inside the PNS is regarded to be essential in re--launching the supernova explosion, a revision of its role in this respect could turn out to be necessary.

description: Since the outbreak of the COVID-19 pandemic, many healthcare facilities have suffered from shortages in medical resources, particularly in Personal Protective Equipment (PPE). In this paper, we propose a game-theoretic approach to schedule PPE orders among healthcare facilities. In this PPE game, each independent healthcare facility optimises its own storage utilisation in order to keep its PPE cost at a minimum. Such a model can reduce peak demand considerably when applied to a variable PPE consumption profile. Experiments conducted for NHS England regions using actual data confirm that the challenge of securing PPE supply during disasters such as COVID-19 can be eased if proper stock management procedures are adopted. These procedures can include early stockpiling, increasing storage capacities and implementing measures that can prolong the time period between successive infection waves, such as social distancing measures. Simulation results suggest that the provision of PPE dedicated storage space can be a viable solution to avoid straining PPE supply chains in case a second wave of COVID-19 infections occurs.

description: We consider Voronoi's reduction theory of positive definite quadratic forms which is based on Delone subdivision. We extend it to forms and Delone subdivisions having a prescribed symmetry group. Even more general, the theory is developed for forms which are restricted to a linear subspace in the space of quadratic forms. We apply the new theory to complete the classification of totally real thin algebraic number fields which was recently initiated by Bayer-Fluckiger and Nebe. Moreover, we apply it to construct new best known sphere coverings in dimensions 9,..., 15.

description: Broad institutional changes, which occurred after Kazakhstan separated from the Soviet Union in 1991, direct performance in the agricultural sector by either creating costs for farmers or shifting costs away. First, the new government called for mass decollectivization that resulted in the emergence of private farm governance structures that were neither financially viable nor efficient. Second, in 1995, a Land Code was established that introduced a system to demarcate collective and state farmland, yet land remains the property of the state. Third, bankruptcy legislation and a rural tax system were designed for the new private farm enterprises. These broad institutional changes resulted in an agricultural sector with high levels of transaction costs and uncertainty for farmers where barter trade predominates on the open market. The problems inherent in the farm restructuring process are largely institutional and therefore lend themselves well to being analyzed within an institutional framework.

description: The Michigan Apple Committee (MAC) is a commodity organization comprised of approximately 1000 apple growers in Michigan. The objective of this study was to evaluate growers' perceptions about the effectiveness of past MAC programs and solicit their opinions about future directions for MAC in order to provide one source of input for Board decisions. In addition, this study provided growers with some information about the broad programmatic areas that are covered under MAC guidelines. In Winter 2003 a mail survey was sent to the entire MAC mailing list (1,123 growers); 282 surveys were returned (25 percent). Overall results of the survey indicate that Michigan apple growers are generally satisfied with the performance of the MAC, but perhaps equally importantly, that many members do not fully understand the function of the MAC. Response to questions about specific programming areas provides more details concerning grower beliefs. Although differences in opinion were generally not identified by grower age or scale of operation, the survey results did highlight some distinct regional differences of opinion within the Michigan apple industry.

Fig. 27G–H
Material examined
ESTONIA • 1 spec.; Haapsalu holm; Adila Formation, Pirgu Regional Stage; TUG 1745-4 • 1 spec.; Vormsi Island, Hosholm shore (tower locality); Adila Formation, Pirgu Regional Stage; GIT 878-323 • 1 spec.; Vohilaid Island, Vohilaid shore (E); Adila Formation, Pirgu Regional Stage; GIT 878-233.
Description
Specimen GIT 878-233 (Fig. 27H) is a fragment of a mature body chamber with a height and width of 33 mm and 20 mm, respectively (CHI = 1.65). The preserved length of the body chamber is 28 mm. The body chamber is slightly exogastrically curved and slightly gibbous. An inconspicuous constriction occurs near the adoral margin of the preserved part where the conch height is ca 30 mm.
The second specimen (GIT 878-323) preserves parts of a mature body chamber and three chambers of the phragmocone (Fig. 27G). The conch height at the base of the body chamber was estimated ca 33 mm. The body chamber is similar in shape and preserved height to that of specimen GIT 878-233. The preserved part of the phragmocone indicates a relatively strong exogastric conch curvature. The third specimen (TUG 1745-4) is a strongly curved fragment of a phragmocone of seven chambers with a maximum conch height of 26 mm.
Remarks
The two specimens belong to a strongly curved, compressed oncocerid species with a gibbous body chamber. Their general conch shape is similar to that of Kallholnoceras. All three specimens are larger than the type species of this monotypic genus, which has a mature conch of 20 mm. Because of the fragmentary character of the material, a species level determination, and the erection of a new species is not currently possible.

description: We study charge transport through a chain of quantum dots. The dots are fully coherent among each other and weakly coupled to metallic electrodes via the dots at the interface, thus modelling a molecular wire. If the non-local Coulomb interactions dominate over the inter-dot hopping we find strongly enhanced shot noise above the sequential tunneling threshold. The current is not enhanced in the region of enhanced noise, thus rendering the noise super-Poissonian. In contrast to earlier work this is achieved even in a fully symmetric system. The origin of this novel behavior lies in a competition of "slow" and "fast" transport channels that are formed due to the differing non-local wave functions and total spin of the states participating in transport. This strong enhancement may allow direct experimental detection of shot noise in a chain of lateral quantum dots.

A REVIEW OF RECENT CHANGES IN MEXICAN AGRICULTURAL POLICY: IMPLICATIONS FOR SMALL SCALE BEAN PRODUCTION

description: Until the early 1980s, Mexican economic policy was characterized by import substitution industrialization. Agriculture's role was to provide a cheap and abundant food supply for the urban sector, and to generate foreign exchange through exports. While Mexico achieved food self-sufficiency by the early 1960s, conflicting policies succeeded in undermining basic grain production and exacerbating an existent dichotomy between traditional and rainfed production. Austerity measures imposed during the 1980s resulting from the collapse of world oil prices further undermined small-scale production. These effects are viewed in the context of the bean subsector, characterized by a bimodal system of production; while the majority of Mexican bean producers are small-scale farmers, most beans are produced on commercial, mechanized farms. Although bean production was affected by mounting inflation during the '70s and '80s, in which static producer prices overrode government subsidies, large scale winter producers benefitted from two-part pricing, begun in the 1980s. Under the Salinas administration, producer prices for beans have risen in recent years, and the Mexican government is embarking on a new rural development program. More importantly, the advent of the North American Free Trade Agreement spells profound changes for the bean subsector. During the 15 year interim period in which tariffs for beans will be phased out, the Mexican government must decide either to invest in increasing the bean sector's productivity, or merely ensure that Mexican consumers have a cheap supply of beans--regardless of whether they are imported or domestically produced.
Navier--Stokes transport coefficients for a model of a confined quasi-two-dimensional granular binary mixture

description: The Navier--Stokes transport coefficients for a model of a confined quasi-two-dimensional granular binary mixture of inelastic hard spheres are determined from the Boltzmann kinetic equation. A normal or hydrodynamic solution to the Boltzmann equation is obtained via the Chapman--Enskog method for states near the local version of the homogeneous time-dependent state. The mass, momentum, and heat fluxes are determined to first order in the spatial gradients of the hydrodynamic fields, and the associated transport coefficients are identified. As expected, they are given in terms of the solutions of a set of coupled linear integral equations. In addition, in contrast to previous results obtained for low-density granular mixtures, there are also nonzero contributions to the first-order approximations to the partial temperatures $T_i^{(1)}$ and the cooling rate $ζ^{(1)}$. Explicit forms for the diffusion transport coefficients, the shear viscosity coefficient, and the quantities $T_i^{(1)}$ and $ζ^{(1)}$ are obtained by assuming the steady-state conditions and by considering the leading terms in a Sonine polynomial expansion. The above transport coefficients are given in terms of the coefficients of restitution, concentration, and the masses and diameters of the components of the mixture. The results apply in principle for arbitrary degree of inelasticity and are not limited to specific values of concentration, mass and/or size ratios. As a simple application of these results, the violation of the Onsager reciprocal relations for a confined granular mixture is quantified in terms of the parameter space of the problem.
