description: Bid-rent curves are incorporated in a stochastic dynamic programming model of land development around a city when farmland generates both positive and negative externalities. The model delineates how the quantities of land in various uses over time should depend on the relative social weights assigned to the competing agricultural externalities.

description: The study of minimal complements in a group or a semigroup was initiated by Nathanson. The notion of minimal complements and being a minimal complement leads to the notion of co-minimal pairs which was considered in a prior work of the authors. In this article, we study which type of subsets in the integers and free abelian groups of higher rank can be a part of a co-minimal pair. We show that a majority of lacunary sequences have this property. From the conditions established, one can show that any infinite subset of any finitely generated abelian group has uncountably many subsets which is a part of a co-minimal pair. Further, the uncountable collection of sets can be chosen so that they satisfy certain algebraic properties.

description: There can exist a hidden sector of the Universe in the form of parallel ''mirror'' world which has the same particle physics as the observable world and interacts with the latter only gravitationally. Big Bang Nucleosynthesis bounds demand that the mirror sector should have a smaller temperature than the ordinary one. This implies that the mirror matter could play a role of dark matter, and in addition its chemical content should be dominated by helium. Here we study the evolutionary and structural properties of the mirror stars which essentially are similar to that of the ordinary stars but with higher helium contents. Being invisible in terms of photons, they could be observed only as MACHOs in the microlensing experiments. Using a numerical code, we compute evolution of stars with large helium abundances (Y = 0.30-0.80) and a wide range of masses, from 0.5 to 10 solar masses. We found that helium dominated mirror star should have much faster evolutionary time (up to a factor 30) than the ordinary star with the same mass. In addition, we show the diagrams of luminosities, effective temperatures, central temperatures and densities, and compute the masses of the He core at ignition and the minimum mass for carbon ignition, for different chemical compositions. The general conclusion is that mirror stars evolve faster as compared to ordinary ones, and explode earlier as type II supernovae, thus enriching the galactic halo of processed mirror gas with higher metallicity, with implications for MACHO observations and galaxy evolution.

description: The glucosinolate (GSL) profiles in different plant parts of the wild-growing species Lepidium draba L. (syn. Cardaria draba Desv.) (Brassicaceae) from Tunisia and Croatia were determined using UHPLC-DAD-MS/MS. The predominant GSLs in both Tunisian and Croatian samples were glucoraphanin and glucosinalbin, with the leaves and flowers being the richest sources. The study also revealed previously unreported GSLs in L. draba, methionine-derived glucoiberin, glucoalyssin, glucohesperin, and glucolesquerellin, as well as tryptophan-derived glucobrassicin and 4-methoxyglucobrassicin. In addition to the variability of GSL content across different plant parts, this study has also shown the limitations of indirect GSL analysis by isothiocyanates using GC-MS, which can lead to incorrect identification of GSLs due to thermal degradation of the isothiocyanates produced.

By Grace of the Flesh : race, sex, representation and David Mura’s memoirs
Creators: name: Chung, Steven
Publisher: name: University of British Columbia
Year: 2009

description: At its most general level, this thesis will engage with theoretical dialogues surrounding the complex intersectionality of race, sex and representation, especially in Asian American cultural production. On another level, I set up an interpretive tension between a Foucauldian genealogical approach and a kind of liberatory post-colonial approach engendered by a number of theorists, including Frantz Fanon. The specific field of representation that I will explore will be pornography—a medium/genre that raises, in a problematic but I think important fashion, the question of sexual discourses and the bodies, desires and pleasures which are their targets. It is a field that also crudely exposes the 'gendering of ethnicity' or the 'eroticization of race,' a signifying practice that has, as many critics have argued, historically formed the racialized subject. The specific texts upon which these issues will be negotiated come from disparate quadrants of ' Asian America.' These will include papers that in various ways formulate a pro-porn position as a hedonistic counter to the 'emasculation' of the Asian body that is produced by the 'white gaze.' The core of this study will be a reading of Japanese American writer David Mura ' s memoirs. In these works, Mura at once 'confesses' to a number of sexual 'transgressions' and 'disorders,' including an addiction to pornography, and further manufactures a concept of race and sexuality out of those experiences. I will argue that M u r a naturalizes or 'essentializes' the raced body along masculinist lines in order to evoke an ethos of psycho-somatic healing and community reconciliation. The thesis will conclude with an attempt to salvage this ethos from what might be called its 'implication in power strategies' by rearticulating it through the work of post-colonial theorist, psychiatrist and revolutionary, Frantz Fanon. His preoccupation with the erotic, colonizing gaze provides an illuminating counterpart to Mura's fixation with the pornographic, racializing gaze and points enigmatically to the possibility of a critical-emancipatory praxis of the body and its representation.

description: Using experimental data on thermal convection, obtained at a Rayleigh number of 1.5 $\times 10^{11}$, it is shown that the temperature structure functions $$, where $ΔT_r$ is the absolute value of the temperature increment over a distance $r$, can be well represented in an intermediate range of scales by $r^{ζ_p} ϕ(r)^{p}$, where the $ζ_p$ are the scaling exponents appropriate to the passive scalar problem in hydrodynamic turbulence and the function $ϕ(r) = 1-a(\ln r/r_h)^2$. Measurements are made in the midplane of the apparatus near the sidewall, but outside the boundary layer.

description: A recent Penning-trap measurement of the masses of 46V and 46Ti leads to a Qec value that disagrees significantly with the previously accepted value, and destroys overall consistency among the nine most precisely characterized T=1 superallowed beta emitters. This raises the possibility of a systematic discrepancy between Penning-trap measurements and the reaction-based measurements upon which the Qec values depended in the past. We carefully re-analyze (n,gamma) and (p,gamma) reaction measurements in the 24 \leq A \leq 28 mass region, and compare the results to very precise Penning-trap measurements of the stable nuclei 24Mg, 26Mg and 28Si. We thus determine upper limits to possible systematic effects in the reaction results, and go on to establish limits for the mass of radioactive 26Al, to which future on-line Penning-trap measurements can be compared. We stress the urgency of identifying or ruling-out possible systematic effects.

It consists in solving the radiative transfer equation in a homogeneous and isothermal plane-parallel atmosphere, with light scattering taken as isotropic and monochromatic. The literature on the subject is reviewed and the existing solution in a finite slab is improved thanks to the introduction of non classical auxiliary functions. Eleven-figure tables of the solution are given for typical values of the input parameters currently met in stellar atmospheres.

description: Several criteria that produce rankings of risk management alternatives are evaluated. The criteria considered are Value at Risk, the Sharpe ratio, the necessary condition for first degree stochastic dominance with a risk free asset, and the necessary condition for second degree stochastic dominance with a risk free asset. The effectiveness of the criteria increases as decision-makers are assumed to be more risk averse and have greater access to financial leverage.

description: Neurodegenerative diseases are closely associated with the amplification and invasion of toxic proteins. In particular Alzheimer's disease is characterized by the systematic progression of amyloid-$β$ and $τ$-proteins in the brain. These two protein families are coupled and it is believed that their joint presence greatly enhances the resulting damage. Here, we examine a class of coupled chemical kinetics models of healthy and toxic proteins in two spatial dimensions. The anisotropic diffusion expected to take place within the brain along axonal pathways is factored in the models and produces a filamentary, predominantly one-dimensional transmission. Nevertheless, the potential of the anisotropic models towards generating interactions taking advantage of the two-dimensional landscape is showcased. Finally, a reduction of the models into a simpler family of generalized Fisher-Kolmogorov-Petrovskii-Piskunov (FKPP) type systems is examined. It is seen that the latter captures well the qualitative propagation features, although it may somewhat underestimate the concentrations of the toxic proteins.

description: We show the significance of the super-Eddington accretion for the cosmic growth of supermassive black holes (SMBHs) with a semi-analytical model for galaxy and black hole evolution. The model explains various observed properties of galaxies and active galactic nuclei at a wide redshift range. By tracing the growth history of individual SMBHs, we find that the fraction of the SMBH mass acquired during the super-Eddington accretion phases to the total SMBH mass becomes larger for less massive black holes and at higher redshift. Even at z = 0, SMBHs with > 1e+9 Msun have acquired more than 50% of their mass by super-Eddington accretions, which is apparently inconsistent with classical Soltan's argument. However, the mass-weighted radiation efficiency of SMBHs with > 1e+8 Msun obtained with our model, is about 0.08 at z = 0, which is consistent with Soltan's argument within the observational uncertainties. We, therefore, conclude that Soltan's argument cannot reject the possibility that SMBHs are grown mainly by super-Eddington accretions.

description: Underwriting schemes are increasingly being used as a basis for price policy in Australian agricultural industries. These policies simultaneously increase average returns and reduce the risk faced by producers.

The optimality properties of underwriting schemes in achieving these targets are examined and compared to those of alternative schemes. Aspects of underwriting scheme design are discussed.

description: Hadronic tau decays represent a clean laboratory for the precise study of quantum chromodynamics (QCD). Observables (sum rules) based on the spectral functions of hadronic tau decays can be related to QCD quark-level calculations to determine fundamental quantities like the strong coupling constant, parameters of the chiral Lagrangian, |V_us|, the mass of the strange quark, and to simultaneously test the concept of quark-hadron duality. Using the best available measurements and a revisited analysis of the theoretical framework, the value alpha_s(m_tau) = 0.345 +- 0.004[exp] +- 0.009[theo] is obtained. Taken together with the determination of alpha_s(m_Z) from the global electroweak fit, this result leads to the most accurate test of asymptotic freedom: the value of the logarithmic slope of 1/alpha_s(s) is found to agree with QCD at a precision of 4%. In another approach, the tau spectral functions can be used to determine hadronic quantities that, due to the nonperturbative nature of long-distance QCD, cannot be computed from first principles. An example for this is the contribution from hadronic vacuum polarization to loop-dominated processes like the anomalous magnetic moment of the muon. This article reviews the measurements of nonstrange and strange tau spectral functions and their phenomenological applications.

description: Machine learning is nowadays the methodology of choice for flare forecasting and supervised techniques, in both their traditional and deep versions, are becoming the most frequently used ones for prediction in this area of space weather. Yet, machine learning has not been able so far to realize an operating warning system for flaring storms and the scientific literature of the last decade suggests that its performances in the prediction of intense solar flares are not optimal. The main difficulties related to forecasting solar flaring storms are probably two. First, most methods are conceived to provide probabilistic predictions and not to send binary yes/no indications on the consecutive occurrence of flares along an extended time range. Second, flaring storms are typically characterized by the explosion of high energy events, which are seldom recorded in the databases of space missions; as a consequence, supervised methods are trained on very imbalanced historical sets, which makes them particularly ineffective for the forecasting of intense flares. Yet, in this study we show that supervised machine learning could be utilized in a way to send timely warnings about the most violent and most unexpected flaring event of the last decade, and even to predict with some accuracy the energy budget daily released by magnetic reconnection during the whole time course of the storm. Further, we show that the combination of sparsity-enhancing machine learning and feature ranking could allow the identification of the prominent role that energy played as an Active Region property in the forecasting process.

description: We present observations of the young multiple system UX Tauri to look for circumstellar disks and for signs of dynamical interactions. We obtained SPHERE/IRDIS deep differential polarization images in the J and H bands. We also used ALMA archival CO data. Large extended spirals are well detected in scattered light coming out of the disk of UX Tau A. The southern spiral forms a bridge between UX Tau A and C. These spirals, including the bridge connecting the two stars, all have a CO (3-2) counterpart seen by ALMA. The disk of UX Tau C is detected in scattered light. It is much smaller than the disk of UX Tau A and has a major axis along a different position angle, suggesting a misalignment. We performed PHANTOM SPH hydrodynamical models to interpret the data. The scattered light spirals, CO emission spirals and velocity patterns of the rotating disks, and the compactness of the disk of UX Tau C all point to a scenario in which UX Tau A has been perturbed very recently (about 1000 years) by the close passage of UX Tau C.

Comparison of 13CO Line and Far-Infrared Continuum Emission as a Diagnostic of Dust and Molecular Gas Physical Conditions: I. Motivation and Modeling

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)

description: Determining temperatures in molecular clouds from ratios of CO rotational lines or from ratios of continuum emission in different wavelength bands suffers from reduced temperature sensitivity in the high-temperature limit. In theory, the ratio of far-IR, submillimeter, or millimeter continuum to that of a 13CO (or C18O) rotational line can place reliable upper limits on the temperature of the dust and molecular gas. Consequently, far-infrared continuum data from the {\it COBE}/{\it DIRBE} instrument and Nagoya 4-m $\cOone$ spectral line data were used to plot 240$\um$/13CO J=1-0 intensity ratios against 140$\um$/240$\um$ dust color temperatures, allowing us to constrain the multiparsec-scale physical conditions in the Orion$ $A and B molecular clouds. The best-fitting models to the Orion clouds consist of two components: a component near the surface of the clouds that is heated primarily by a very large-scale (i.e. $\sim 1 $kpc) interstellar radiation field and a component deeper within the clouds. The former has a fixed temperature and the latter has a range of temperatures that varies from one sightline to another. The models require a dust-gas temperature difference of 0$\pm 2 $K and suggest that 40-50% of the Orion clouds are in the form of dust and gas with temperatures between 3 and 10$ $K. These results have a number implications that are discussed in detail in later papers. These include stronger dust-gas thermal coupling and higher Galactic-scale molecular gas temperatures than are usually accepted, an improved explanation for the N(H$_2$)/I(CO) conversion factor, and ruling out one dust grain alignment mechanism.
description: The second version includes some discussion of why previous models of dust-gas thermal coupling were simplistic. Paper III in the series discusses this in more detail. Also, some minor errors were corrected. These errors in no way affect the final conclusions

description: Droughts are a feature of the Australian agricultural scene. Most farmers develop successful strategies to grapple with drought. The purchased fodder and interest rate subsidies used in the 1982-83 drought are analysed. As partial input subsidies, they had serious flaws in meeting goals of efficiency, equity and welfare support. Alternative policies to provide incentives for rational private decision making and to provide direct welfare support are discussed and advocated as a preferable approach to future droughts.

description: Low-mass satellites around Milky Way (MW)-like galaxies are important probes of small scale structure and galaxy formation. However, confirmation of satellite candidates with distance measurements remains a key barrier to fast progress in the Local Volume (LV). We measure the surface brightness fluctuation (SBF) distances to recently cataloged candidate dwarf satellites around 10 massive hosts within $D<12$ Mpc to confirm association. The satellite systems of these hosts are complete and mostly cleaned of contaminants down to $M_g{\sim}-9$ to $-10$, within the area of the search footprints. Joining this sample with hosts surveyed to comparable or better completeness in the literature, we explore how well cosmological simulations combined with common stellar to halo mass relations (SHMR) match observed satellite luminosity functions in the classical satellite luminosity regime. Adopting a SHMR that matches hydrodynamic simulations, the predicted overall satellite abundance agrees well with the observations. The MW is remarkably typical in its luminosity function amongst LV hosts. Contrary to recent results, we find that the host-to-host scatter predicted by the model is in close agreement with the scatter between the observed systems, once the different masses of the observed systems are taken into account. However, we find significant evidence that the observed systems have more bright and fewer faint satellites than the SHMR model predicts, necessitating a higher normalization of the SHMR around halo masses of $10^{11}$ \msun\ than present in common SHMRs. These results demonstrate the utility of nearby satellite systems in inferring the galaxy-subhalo connection in the low-mass regime.

description: We derive the triply differential spectrum for the inclusive rare decay B -> Xs l+ l- in the shape function region, in which Xs is jet-like with $mX^2 \lesssim mb Λ_QCD$. Experimental cuts make this a relevant region. The perturbative and non-perturbative parts of the matrix elements can be defined with the Soft-Collinear Effective Theory, which is used to incorporate alphas corrections consistently. We show that, with a suitable power counting for the dilepton invariant mass, the same universal jet and shape functions appear as in B-> Xs gamma and B-> Xu l nu decays. Parts of the usual alphas(m_b) corrections go into the jet function at a lower scale, and parts go into the non-perturbative shape function. For B -> Xs l+ l-, the perturbative series in alphas are of a different character above and below mu=mb. We introduce a ``split matching'' method that allows the series in these regions to be treated independently.

description: Decision theory affords a means for the objectively rational use of information in decision-making. Concern has been expressed from time to time that the application of decision theory is, or is sometimes, of doubtful appropriateness. In this paper an attempt is made to identify a principal source of this concern and the mis-specification of decision problems using decision theory that it implies. Suggestions are offered as to how the merits of the use of decision theory might be retained in decision-making situations where doubts may arise about the appropriateness of its application.

description: The space-requirement for routing-tables is an important characteristic of routing schemes. For the cost-measure of minimizing the total network load there exist a variety of results that show tradeoffs between stretch and required size for the routing tables. This paper designs compact routing schemes for the cost-measure congestion, where the goal is to minimize the maximum relative load of a link in the network (the relative load of a link is its traffic divided by its bandwidth). We show that for arbitrary undirected graphs we can obtain oblivious routing strategies with competitive ratio $\tilde{\mathcal{O}}(1)$ that have header length $\tilde{\mathcal{O}}(1)$, label size $\tilde{\mathcal{O}}(1)$, and require routing-tables of size $\tilde{\mathcal{O}}(\operatorname{deg}(v))$ at each vertex $v$ in the graph. This improves a result of Räcke and Schmid who proved a similar result in unweighted graphs.

Subjects: Risk and Uncertainty

description: Project appraisal under uncertainty should, in general, be worked in terms of carefully computed expected or mean values of uncertain elements. The major exceptions are when: (a) project returns are large relative to national income; or (b) project returns are highly correlated with other national income. Approximate procedures have been developed for computing risk adjustments in each of these special cases singly, but here, a more comprehensive procedure is described that encompasses both cases separately and jointly.

description: In livestock feeding experiments the problem of recursiveness arises because the quantity of feed consumed by an animal is a function of its past history of feeding. The problem is most acute where experiments are designed to analyse sub ad lib feeding. The analysis of such experiments encounters two important problems. The first is that the actual quantity of feed consumed is an endogenous variable and is not directly under the control of the experimenter or the livestock producer. The second problem is the mathematical complexity of the relationships involved. A solution is suggested as a quasi reduced-form model.

description: The radial spatial distribution of low-mass satellites around a Milky Way (MW)-like host is an important benchmark for simulations of small-scale structure. The distribution is sensitive to the disruption of subhalos by the central disk and can indicate whether the disruption observed in simulations of MW analogs is artificial (i.e., numeric) or physical in origin. We consider a sample of 12 well-surveyed satellite systems of MW-like hosts in the Local Volume that are complete to $M_V

description: We investigated the dependence of giant tunnel magnetoresistance (TMR) on the thickness of an MgO barrier and on the annealing temperature of sputtered CoFeB/MgO/CoFeB magnetic tunnel junctions deposited on SiO2/Si wafers. The resistance-area product exponentially increases with MgO thickness, indicating that the quality of MgO barriers is high in the investigated thickness range of 1.15-2.4 nm. High-resolution transmission electron microscope images show that annealing at 375 C results in the formation of crystalline CoFeB/MgO/CoFeB structures, even though CoFeB electrodes are amorphous in the as-sputtered state. The TMR ratio increases with annealing temperature and is as high as 260% at room temperature and 403% at 5 K.

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: In the conventional theory of hopping transport the positions of localized electronic states are assumed to be fixed, and thermal fluctuations of atoms enter the theory only through the notion of phonons. On the other hand, in 1D and 2D lattices, where fluctuations prevent formation of long-range order, the motion of atoms has the character of the large scale diffusion. In this case the picture of static localized sites may be inadequate. We argue that for a certain range of parameters, hopping of charge carriers among localization sites in a network of 1D chains is a much slower process than diffusion of the sites themselves. Then the carriers move through the network transported along the chains by mobile localization sites jumping occasionally between the chains. This mechanism may result in temperature independent mobility and frequency dependence similar to that for conventional hopping.

Nonlinear traveling waves as a framework for understanding turbulent drag reduction

description: Nonlinear traveling waves that are precursors to laminar-turbulent transition and capture the main structures of the turbulent buffer layer have recently been found to exist in all the canonical parallel flow geometries. We study the effect of polymer additives on these "exact coherent states" (ECS), in the plane Poiseuille geometry. Many key aspects of the turbulent drag reduction phenomenon are found, including: delay in transition to turbulence; drag reduction onset threshold; diameter and concentration effects. Furthermore, examination of the ECS existence region leads to a distinct prediction, consistent with experiments, regarding the nature of the maximum drag reduction regime. Specifically, at sufficiently high wall shear rates, viscoelasticity is found to completely suppress the normal (i.e. streamwise-vortex-dominated) dynamics of the near wall region, indicating that the maximum drag reduction regime is dominated by a distinct class of flow structures.

Year: 1967
Subjects: Research Methods/ Statistical Methods

description: Multi-period linear programming models are classified initially. The main interest of this paper is in models of cyclical activity. The conditions under which such models lead to stable repetitive optimal solutions are defined. A simple technique is presented by which this stable solution (termed here the "stable core") can be derived without recourse to solving a full extended matrix. Firm-level applications of this model in agriculture are discussed.

description: We present a method to perform fault-tolerant single-qubit gate operations using Landau-Zener tunneling. In a single Landau-Zener pulse, the qubit transition frequency is varied in time so that it passes through the frequency of the radiation field. We show that a simple three-pulse sequence allows eliminating errors in the gate up to the third order in errors in the qubit energies or the radiation frequency.

description: We evaluate abundance anomalies generated in patches of the universe where the baryon-to-photon ratio was locally enhanced by possibly many orders of magnitude in the range $η= 10^{-10} - 10^{-1}$. Our study is motivated by the possible survival of rare dense regions in the early universe, the most extreme of which, above a critical threshold, collapsed to form primordial black holes. If this occurred, one may expect there to also be a significant population of early-forming stars that formed in similar but subthreshold patches. We derive a range of element abundance signatures by performing BBN simulations at high values of the baryon-to-photon ratio that may be detectable in any surviving first generation stars of around a solar mass. Our predictions apply to metal-poor galactic halo stars, to old globular star clusters and to dwarf galaxies, and we compare with observations in each of these cases.
