description: We study the stability of the replica-symmetric solution of a two-sublattice infinite-range spin-glass model, which can describe the transition from antiferromagnetic to spin glass state. The eigenvalues associated with replica-symmetric perturbations are in general complex. The natural generalization of the usual stability condition is to require the real part of these eigenvalues to be positive. The necessary and sufficient conditions for all the roots of the secular equation to have positive real parts is given by the Hurwitz criterion. The generalized stability condition allows a consistent analysis of the phase diagram within the replica-symmetric approximation.

description: We study the effect of variations of the electromagnetic coupling on the process of generation of primordial magnetic fields. We find that only through a significant growth of the electromagnetic coupling minimum seed fields can be produced. We also show that, if through some process in the early Universe the photon acquires a mass that leads, thanks to inflation, to the generation of primordial magnetic fields, then the influence of variations of the electromagnetic coupling amounts essentially to the results due to the photon effective mass alone.

description: We calculate the contributions of the flavor changing scalar ($FCS$) couplings arised from topcolor-assisted technicolor ($TC2$) models at tree-level to the $tγ$ and $tZ$ production at the Tevatron and $LHC$ experiments. We find that the production cross sections are very small at the Tevatron with $\sqrt{s}=1.96TeV$, which is smaller than 5 fb in most of the parameter space of $TC2$ models. However, the virtual effects of the $FCS$ couplings on the $tγ(Z)$ production can be easily detected at the $LHC$ with $\sqrt{s}=14TeV$ via the final state $γl\barνb$ ($l^{+}l^{-}l\barνb$).

description: While recommendation plays an increasingly critical role in our living, study, work, and entertainment, the recommendations we receive are often for irrelevant, duplicate, or uninteresting products and services. A critical reason for such bad recommendations lies in the intrinsic assumption that recommended users and items are independent and identically distributed (IID) in existing theories and systems. Another phenomenon is that, while tremendous efforts have been made to model specific aspects of users or items, the overall user and item characteristics and their non-IIDness have been overlooked. In this paper, the non-IID nature and characteristics of recommendation are discussed, followed by the non-IID theoretical framework in order to build a deep and comprehensive understanding of the intrinsic nature of recommendation problems, from the perspective of both couplings and heterogeneity. This non-IID recommendation research triggers the paradigm shift from IID to non-IID recommendation research and can hopefully deliver informed, relevant, personalized, and actionable recommendations. It creates exciting new directions and fundamental solutions to address various complexities including cold-start, sparse data-based, cross-domain, group-based, and shilling attack-related issues.

description: The isothermal gas sphere is well known as a powerful tool to model many problems in astrophysics, physics, chemistry, and engineering. This singular differential equation has not an exact solution and solved only by numerical and approximate methods. In the present paper and within the framework of the Newtonian hydrostatic equilibrium, we have developed general analytical formulations for the fractional isothermal gas sphere. To obtain analytical expressions for mass, radius, and density, besides the fractional isothermal gas sphere, we used the conformable fractional calculus. Using the series expansion method, we obtained a general recurrences relation, which allows us to determine the series coefficients. The comparison of the series solution with the numerical ones for the fractional parameter α=1 is good for dimensional parameters up to x=3.2, beyond this value, the series diverges. We applied a combination of Euler-Abel and Pade techniques to accelerate the series, therefore accelerated series converge to the numerical desired value. We analyzed some physical parameters of a typical model of the neutron stars such as the mass-radius relation, density, and pressure ratio for different models. We found that the current models of the conformable neutron stars had smaller volumes and masses than both stars in the context of modified Rienmann-Liouville derivatives as well as the integer one.

The experience of health in chronic illness : the perspectives of adults diagnosed with end-stage renal disease during adolescence
Creators: name: Venables, Lisa Jane
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the experience of health in chronic illness from the perspectives of adults diagnosed with end-stage renal disease (ESRD) during adolescence. Grounded theory methodology was used to guide this qualitative study. Data was collected in two interviews from eight young adults who were diagnosed with ESRD during adolescence. Interviews were audiotaped and transcribed for analysis using the constant comparative method. Five themes emerged from the data and included; the diagnosis in adolescence, having a sense of control over ESRD, facilitators of control, threats to control, and descriptions of the concept "health". The findings were developed into a grounded theory. The experience of health involves the fluctuating state of perceived control and perceived loss of control over the disease as individuals are faced with both facilitators and threats to control. When individuals are diagnosed with ESRD during adolescence, they initially perceive having no control over the disease because others assume control, they are unable to do things that are important, and they feel the disease sets them apart from their peers. This lack of control and their desire for independence and to be like their normal peers, results in the adolescent with ESRD attempting to take control. Having a sense of control over ESRD becomes the preferred way of being throughout adolescence and into adulthood. When individuals are able to have a sense of control over the disease they are able to experience a sense of health which allows them to do what they want, have the abilities of a normal person, and not focus on the disease. The theory raises issues regarding the fluctuating nature of the experience of health, the implications of the diagnosis of a chronic illness in adolescence, and the concept of perceived control as a balance between being controlled by the disease and controlling the disease by not attending to its physiological needs. These issues were discussed in relation to current literature regarding the diagnosis of chronic illness in adolescence, issues of compliance, and models of chronic illness.

description: Videogames are nowadays one of the biggest entertainment industries in the world. Being part of this industry means competing against lots of other companies and developers, thus, making fanbases of vital importance. They are a group of clients that constantly support your company because your video games are fun. Videogames are most entertaining when the difficulty level is a good match for the player's skill, increasing the player engagement. However, not all players are equally proficient, so some kind of difficulty selection is required. In this paper, we will present Dynamic Difficulty Adjustment (DDA), a recently arising research topic, which aims to develop an automated difficulty selection mechanism that keeps the player engaged and properly challenged, neither bored nor overwhelmed. We will present some recent research addressing this issue, as well as an overview of how to implement it. Satisfactorily solving the DDA problem directly affects the player's experience when playing the game, making it of high interest to any game developer, from independent ones, to 100 billion dollar businesses, because of the potential impacts in player retention and monetization.

description: The problem of energy conservation in the lattice Boltzmann method is solved. A novel model with energy conservation is derived from Boltzmann's kinetic theory. It is demonstrated that the full thermo-hydrodynamics pertinent to the Boltzmann equation is recovered in the domain where variations around the reference temperature are small. Simulation of a Poiseuille micro-flow is performed in a quantitative agreement with exact results for low and moderate Knudsen numbers. The new model extends in a natural way the standard lattice Boltzmann method to a thermodynamically consistent simulation tool for nearly-incompressible flows.

description: Deep learning based medical image diagnosis has shown great potential in clinical medicine. However, it often suffers two major difficulties in real-world applications: 1) only limited labels are available for model training, due to expensive annotation costs over medical images; 2) labeled images may contain considerable label noise (e.g., mislabeling labels) due to diagnostic difficulties of diseases. To address these, we seek to exploit rich labeled data from relevant domains to help the learning in the target task via {Unsupervised Domain Adaptation} (UDA). Unlike most UDA methods that rely on clean labeled data or assume samples are equally transferable, we innovatively propose a Collaborative Unsupervised Domain Adaptation algorithm, which conducts transferability-aware adaptation and conquers label noise in a collaborative way. We theoretically analyze the generalization performance of the proposed method, and also empirically evaluate it on both medical and general images. Promising experimental results demonstrate the superiority and generalization of the proposed method.

description: We use very deep (R_lim=27) UGRI imaging to study the evolution of the faint end of the UV-selected galaxy luminosity function from z~4 to z~2. We find that the number of sub-L* galaxies increases from z~4 to z~3 while the number of bright ones appears to remain constant. We find no evidence for continued evolution to lower redshift, z~2. If real, this differential evolution of the luminosity function suggests that differentially comparing key diagnostics of dust, stellar populations, etc. as a function of z and L may let us isolate the key mechanisms that drive galaxy evolution at high redshift and we describe several such studies currently underway.

description: We develop a conceptual framework that integrates quality of output and transaction costs in the choice of marketing channels. We estimate a reduced-form Tobit model and a semi-reduced logit model using a farm-level cross-sectional dataset to measure the effects of transaction costs in farming ability to make sales to indirect markets (retailers and wholesalers). We find strong empirical evidence that existing organic retail and wholesale markets impose considerable barriers to entry on individual organic farmers. The effects of transaction costs are asymmetric between farmers, those who transitioned from conventional farming and those who did not. Those who did are overall favored, and those who did not are constrained by more types of transaction costs and are constrained more severely than those who did. We argue that an effective policy should target the least favored farmers by encouraging or mandating distributors and retailers have a more transparent and objective process in selecting organic suppliers, such that all farmers would have an equal opportunity to be successful in selling to indirect markets.

description: We discuss atmosphere models of HD209458b in light of the recent day-side flux measurement of HD209458b's secondary eclipse by Spitzer-MIPS at 24 microns. In addition, we present a revised secondary eclipse IRTF upper limit at 2.2 microns which places a stringent constraint on the adjacent H2O absorption band depths. These two measurements are complementary because they are both shaped by H2O absorption and because the former is on the Wien tail of the planet's thermal emission spectrum and the latter is near the thermal emission peak. A wide range of models fit the observational data, confirming our basic understanding of hot Jupiter atmospheric physics. Although a range of models are viable, some models at the hot and cold end of the plausible temperature range can be ruled out. One class of previously unconsidered hot Jupiter atmospheric models that fit the data are those with C/O >~ 1 (as Jupiter may have), which have a significant paucity of H2O compared to solar abundance models with C/O = 0.5. The models indicate that HD209458b is in a situation intermediate between pure in situ reradiation and very efficient redistribution of heat; one which will require a careful treatment of atmospheric circulation. We discuss how future wavelength-dependent and phase-dependent observations will further constrain the atmospheric circulation regime. In the shorter term, additional planned measurements for HD209458b, especially Spitzer IRAC photometry, should lift many of the model degeneracies. Multiwavelength IR observations constrain the atmospheric structure and circulation properties of hot Jupiters and thus open a new chapter in quantitative extrasolar planetology.

description: The average shape of the pulse in Barkhausen noise has been recently proposed as a tool to compare models and experiments. We compute theoretically the pulse shape of Barkhausen noise in a model describing the motion of a domain wall in an effective Brownian potential. In this framework, the pulse shape is related to the properties of the excursion of a random process in a $c\log(x)-kx$ potential. We record the Barkhausen noise in polycristalline ${FeSi}$ materials, and compare the pulse shape with the one predicted by the domain wall model.

description: The validity of the utility concept, particularly in an expected utility framework, has been questioned because of its inability to predict revealed behavior. In this paper we focus on the global shape of the utility function instead of the local shape of the utility function. We examine the extent of heterogeneity in the global shape of the utility function of decision makers and test whether its shape predicts strategic risk management behavior. We assess the utility functions and relate them to strategic decisions for portfolio managers (N = 104) and hog farmers (N = 239). The research design allows us to examine the robustness of our results and the extent to which the results can be generalized. Furthermore, we assess the shape of the utility functions for these decision makers applying two different methods. This allows us to further test the robustness of our empirical results. If there exists a relationship between the shape of the utility function and strategic decisions, both methods should yield the same result. The empirical results indicate that the global shape of the utility function differs across decision makers (fully concave or convex versus S-shaped), and that the global shape predicts strategic decisions (e.g., asset allocation strategy in the case of portfolio managers; type of production process employed in the case of hog farmers). These findings support the notion that the often criticized concept of utility is a useful concept when studying actual behavior, and highlight the importance of considering decision-maker behavior over a wide outcome range when examining strategic behavior.

Firstly, we deal with elementary properties and examine, existence, and characterizations of generalized quasi-Einstein normal metric contact pair manifold. Secondly, the generalized quasi-constant curvature of normal metric contact pair manifolds are studied and it is proven that a normal metric contact pair manifold with generalized quasi-constant curvature is a generalized quasi-Einstein manifold. Normal metric contact pair manifolds satisfying cyclic Ricci tensor and the Codazzi type of Ricci tensor are considered and its shown that a generalized quasi-Einstein normal metric contact pair manifold does not satisfy Codazzi type of Ricci tensor. Finally, we work on normal metric contact pair manifolds satisfying certain curvature conditions related to $ \mathcal{M}- $projective, conformal, and concircular curvature tensors. We show that a normal metric contact pair manifold with generalized quasi-constant curvature is locally isometric to the Hopf manifold $ S^{2n+1}(1) \times S^1 $.

description: To date, there is only fragmented and anecdotal information about the impact of the recommendations of market advisory services (MAS) on producers' decision-making. A conceptual framework is developed in which, among others, producers' risk attitudes and risk perceptions; producers' perceptions about MAS performance and delivery; and match between the MAS and the producers' marketing philosophy are hypothesized to influence the impact of MAS on producers' marketing decisions. Data from 656 U.S. producers were used and the impact of MAS on producers' marketing decisions was tested using an ordered probit model. The empirical results reveal that not only the perceived MAS performance, but also the way in which MAS recommendations are delivered, and the match between MAS and producer's marketing philosophy are important factors explaining the impact of MAS recommendations.

description: Building on earlier work by Cramer, this paper tests for price-advertising interaction effects in the U.S. non-alcoholic beverage market. Full and restricted specifications of the Rotterdam model are tested along with compensated and first difference double-log models using annual time-series data for the period 1970-2000. Results are mixed in that the full Rotterdam and first difference double-log models fail to reject the null hypothesis of no rotation while the restricted Rotterdam and compensated double-log models indicate rejection. One reason for the ambiguous results may be multicollinearity problems associated with the unrestricted models. Still, our overall conclusion is that there is little solid evidence to suggest that generic advertising rotated the demand curves for non-alcoholic beverages in the United States.

description: Using the intertwining relation we construct a pseudosuperpartner for a (non-Hermitian) Dirac-like Hamiltonian describing a two-level system interacting in the rotating wave approximation with the electric component of an electromagnetic field. The two pseudosuperpartners and pseudosupersymmetry generators close a quadratic pseudosuperalgebra. A class of time dependent electric fields for which the equation of motion for a two level system placed in this field can be solved exactly is obtained. New interesting phenomenon is observed. There exists such a time-dependent detuning of the field frequency from the resonance value that the probability to populate the excited level ceases to oscillate and becomes a monotonically growing function of time tending to 3/4. It is shown that near this fixed excitation regime the probability exhibits two kinds of oscillations. The oscillations with a small amplitude and a frequency close to the Rabi frequency (fast oscillations) take place at the background of the ones with a big amplitude and a small frequency (slow oscillations). During the period of slow oscillations the minimal value of the probability to populate the excited level may exceed 1/2 suggesting for an ensemble of such two-level atoms the possibility to acquire the inverse population and exhibit lasing properties.

description: Livestock waste pollutes multiple environmental media along multiple dimensions. This study explores the economic and environmental implications of single-medium and coordinated multi-media policies for reducing manure-related externalities, with particular attention paid to tradeoffs that occur when policies designed to correct an externality in one medium ignore externalities in other media.

description: Most studies measuring asymmetric adjustments in vertical price transmissions fail to provide empirical support to explain such behavior. The literature invokes theoretical models, which derive asymmetric behavior based on variables that are difficult to measure such as oligopolies' coordination policies, market imperfections or menu costs. Therefore, with no empirical support explaining the asymmetries, these studies leave no room for policy implementation. In this paper I relate asymmetric price responses to a theory of behavior under risk driven by the perishable rate of the goods. Retailers of a perishable good facing an increment in the wholesale price may decide not to increase their prices for fear of being left with a spoiled product. Using three agricultural products with different perishable rates I reject the null hypothesis of symmetric adjustments in the most perishable product but fail to reject for the less perishable goods. The nonlinear responses are consistent with the prediction of the model. The test for asymmetries uses a threshold cointegration technique where the threshold level and the cointegration vector are estimated from the data instead of being imposed by the econometrician.

description: We present 3D general relativistic magnetohydrodynamic (GRMHD) simulations of the accretion flow surrounding Sagittarius A* that are initialized using larger-scale MHD simulations of the $\sim$ 30 Wolf--Rayet (WR) stellar winds in the Galactic center. The properties of the resulting accretion flow on horizon scales are set not by ad hoc initial conditions but by the observationally constrained properties of the WR winds with limited free parameters. For this initial study we assume a non-spinning black hole. Our simulations naturally produce a $\sim 10^{-8} M_\odot$ yr$^{-1}$ accretion rate, consistent with previous phenomenological estimates. We find that a magnetically arrested flow is formed by the continuous accretion of coherent magnetic field being fed from large radii. Near the event horizon, the magnetic field is so strong that it tilts the gas with respect to the initial angular momentum and concentrates the originally quasi-spherical flow to a narrow disk-like structure. We also present 230 GHz images calculated from our simulations where the inclination angle and physical accretion rate are not free parameters but are determined by the properties of the WR stellar winds. The image morphology is highly time variable. Linear polarization on horizon scales is coherent with weak internal Faraday rotation.

description: Constraints on the heavy sterile neutrino mixing angles are studied in the framework of a minimal supersymmetric ${\rm SO}(10)$ model with {\it double see-saw mechanism}. A new singlet matter in addition to the right-handed neutrinos is introduced to realize the double see-saw mechanism. The minimal ${\rm SO}(10)$ model gives an unambiguous Dirac neutrino mass matrix, which enables us to predict the masses and the mixing angles in the enlarged $9 \times 9$ neutrino mass matrix. Mixing angles between the light Majorana neutrinos and the heavy sterile neutrinos are shown to be within the LEP experimental bound on all ranges of the Majorana phases.

description: In Southern Alberta, agriculture is the largest water user. Thirteen irrigation districts plus numerous private irrigators hold licenses to withdraw more than 75% of the available surface water. Water use decisions made by farmers in irrigation districts have significant impacts on the productivity of water use and on environmental outcomes (instream flow needs) throughout the South Saskatchewan River Basin (SSRB), especially during periods of drought. The objective of this paper is to investigate current and alternative water allocation strategies and their effects on crop choices with a focus on the irrigation districts in the Bow River Sub-basin of the SSRB. A mathematical programming model is developed to optimize economic returns from crop production, subject to specified restrictions imposed by water supply, institutional and hydrological conditions, production technology and land characteristics. Positive Mathematical Programming is used for model calibration with data from 2002-2003 provided by Alberta Agriculture Food and Rural Development. This research provides an explicit framework for the design and comparison of water policy options in Southern Alberta. The findings provide information to address the twin objectives of increasing the productivity of agricultural water use and meeting the environmental flow requirements of the Bow River Basin.

description: The objective of an expert recommendation system is to trace a set of candidates' expertise and preferences, recognize their expertise patterns, and identify experts. In this paper, we introduce a multimodal classification approach for expert recommendation system (BERTERS). In our proposed system, the modalities are derived from text (articles published by candidates) and graph (their co-author connections) information. BERTERS converts text into a vector using the Bidirectional Encoder Representations from Transformer (BERT). Also, a graph Representation technique called ExEm is used to extract the features of candidates from the co-author network. Final representation of a candidate is the concatenation of these vectors and other features. Eventually, a classifier is built on the concatenation of features. This multimodal approach can be used in both the academic community and the community question answering. To verify the effectiveness of BERTERS, we analyze its performance on multi-label classification and visualization tasks.

description: As water becomes scarcer in northern China, designing policies that can induce water users to save water has become one of the most important tasks facing China's leader. Past water policies may not be a solution for the water scarcity problem in the long run. This paper looks at a new water policy: increasing water prices so as to provide water users with direct incentives to save water. Using a methodology that allows us to incorporate the resource constraints, we are able to recover the true price of water with a set of plot level data. Our results show that farmers are quite responsive if the correct price signal is used, unlike estimates of price elasticities that are based on traditional methods. Our estimation results show that water is severely under priced in our sample areas in China. As a result, water users are not likely to respond to increases in water prices. Thus as the first step to establishing an effective water pricing policy, policy makers must increase water price to the level of VMP so that water price reflects the true value of water, the correct price signal. Increases in water prices once they are set at the level of VMP, however, can lead to significant water savings. However, our analysis also shows that higher water prices also affect other aspects of the rural sector. Higher irrigation costs will lower the production of all crops, in general, and that of grain crops, in particular. Furthermore, when facing higher irrigation costs, households suffer income losses. Crop income distribution also worsens with increases in water prices. In summary, our paper provides both good news and bad news to policy makers. On the one hand, water pricing policies obviously have great potential for curbing demand and helping policy makers address the emerging water crisis. On the other hand, dealing with the negative production and income impacts of higher irrigation cost will pose a number of challenges to policy makers. In other words, if China's leaders plan to increase water prices to address the nation's water crisis, an integrated package of policies will be needed to achieve water savings without hurting rural incomes or national food security.

description: Exclusive reactions induced at high momentum transfer in few body systems provide us with an original way to study the production and propagation of hadrons in cold nuclear matter. In very well defined parts of the phase space, the reaction amplitude develops a logarithmic singularity. It is on solid ground since it depends only on on-shell elementary amplitudes and on low momentum components of the nuclear wave function. This is the best window to study the propagation of exotic configurations of hadrons such as, for instance, the onset of color transparency. It may appear earlier in meson photo-production reactions, more particularly in the strange sector, than in more classical quasi elastic scattering of electrons. More generally, those reactions provide us with the best tool to determine the cross section of the scattering of various hadrons (strange particles, vector mesons) from the nucleon and to access the production of possible exotic states.
