description: The heat kernel expansion for field theory at finite temperature is constructed. It is based on the imaginary time formalism and applies to generic Klein-Gordon operators in flat space-time. Full gauge invariance is manifest at each order of the expansion and the Polyakov loop plays an important role at any temperature. The expansion is explicitly worked out up to operators of dimension six included. The method is then applied to compute the one loop effective action of QCD at finite temperature with massless quarks. The calculation is carried out within the background field method in the $\bar{\text{MS}}$ scheme up to dimension six operators. Further, the action of the dimensionally reduced effective theory at high temperature is also computed to the same order. Existing calculations are reproduced and new results are obtained in the quark sector for which only partial results existed up to dimension six.

On the Secondary's Rotation in Synchronous Binary Asteroid

description: This paper studies the secondary's rotation in a synchronous binary asteroid system in which the secondary enters the 1:1 spin-orbit resonance. The model used is the planar full two-body problem composed of a spherical primary plus a tri-axial ellipsoid secondary. Compared with classical spin-orbit work, there are two differences: (1) Influence on the mutual orbit from the secondary's rotation is considered; (2) Instead of the Hamiltonian approach, the approach of periodic orbits is adopted. Our studies find: (1) Genealogy of the two families of periodic orbits is same as that of the families around triangular libration points in the restricted three-body problem. That is, the long-period family terminates onto a short-period orbit travelling N times; (2) In the limiting case where the secondary's mass is negligible, our results can be reduced to the classical spin-orbit theory, by equating the long-period orbit with the free libration, and by equating the short-period orbit with the forced libration caused by orbit eccentricity. However, the two models show obvious differences when the secondary's mass is non-negligible. (3) By studying the stability of periodic orbits, for a specific binary asteroid system, we are able to obtain the maximum libration amplitude of the secondary (which is usually less than 90 degree), and the maximum mutual orbit eccentricity which does not break the secondary's synchronous state. We also find the anti-correlation between the secondary's libration amplitude and the orbit eccentricity. The (65803) Didymos system is taken as an example to show the results.

description: The neutron star binary SAX J1747.0-2853, located in the Galactic Center region at about 0.5 deg from Sgr A* and at a distance of 9 kpc, has been observed in outburst four times (1998, 1999, 2000 and 2001) by BeppoSAX and RossiXTE. At the time of its discovery in 1998 the source was observed in a low/hard state, showing a hard tail with a high energy cutoff of 70 keV. About two years later the source reappeared about one order of magnitude brighter in the X-rays (0.5-10 keV) and with a significantly steeper spectrum. As was the case for the low state, the data could be fitted by an input model based on two continuum primary components: a) a soft thermal excess, which is ~4 times more luminous than the one found in hard state; b) a non-thermal component which is compatible with either a power-law or a comptonization spectrum. The soft component is equally well described by pure blackbody or multi-color disk emission, with significantly higher temperature than observed in low state (~1.3 vs. the ~0.5 keV assuming pure blackbody). For this model, the flux of the non-thermal component below ~10 keV is a significant fraction of the total X-ray flux, i.e. greater than ~50% in the 2-10 keV band.

description: We discuss a continuous variables method of quantum key distribution employing strongly polarized coherent states of light. The key encoding is performed using the variables known as Stokes parameters, rather than the field quadratures. Their quantum counterpart, the Stokes operators $\hat{S}_i$ (i=1,2,3), constitute a set of non-commuting operators, being the precision of simultaneous measurements of a pair of them limited by an uncertainty-like relation. Alice transmits a conveniently modulated two-mode coherent state, and Bob randomly measures one of the Stokes parameters of the incoming beam. After performing reconciliation and privacy amplification procedures, it is possible to distill a secret common key. We also consider a non-ideal situation, in which coherent states with thermal noise, instead of pure coherent states, are used for encoding.

description: This report documents the procedures used to delineate 382 labor market areas (geographic areas encompassing both the place of work and the place of residence of a local population) for the United States. The data used to delineate these labor market areas (LMA's) were the 1980 Census journey-to-work data for counties and county-equivalents in the 50 States and the District of Columbia. Matrices of these data were constructed to indicate the relative strength of the commuting ties between each pair of counties. The results of a hierarchical cluster analysis on these matrices were then used to identify groups of counties with strong shared commuting ties.

description: We have combined existing optical magnitudes for stars in seven open clusters and 54 field stars with the corresponding JHKs photometry from the Two Micron All Sky Survey (2MASS). Combining optical with near-IR photometry broadens the color baseline minimizing the influence of photometric errors and allows better discrimination between cluster stars and contaminating foreground and background populations. The open clusters in this study include NGC 2516, M35, M34, NGC 3532, M37, M67, and NGC 188. The field stars we are using possess high quality Hipparcos parallaxes and well-determined metal abundances allowing us to empirically determine the dependence of (V-K) color on metal abundance in the range -0.45<=[Fe/H]<=+0.35. Using this relation along with the parallaxes of the field stars, we are able to construct an unevolved main sequence in the [Mv,(V-K)o] diagram for a specific abundance. These diagrams are then used to fit to the cluster main sequences in the [V,V-K] color-magnitude diagram in order to estimate a distance for each open cluster. We find that the resultant distances are within the range of distances found in the literature via the main sequence fitting technique. It is hoped that this will spur an expansion of the current (limited) database of star clusters with high quality (V-K) photometry down to the unevolved main sequence.

description: Investment in agricultural capital construction is an important factor in improving China's agricultural productivity and international competitiveness. In recent years, the attention to the investment in agricultural capital construction has been lifted to a strategic height. However, there is still little research on the investment in agricultural capital construction. From the perspective of investment of different ministries and commissions, this paper systematically analyzed current situations, problems, and came up with recommendations for the investment in the agricultural capital construction. According to the results, (i) from 1983 to the present, China's investment in agricultural capital construction experienced three stages. Especially after 2010, the scale of investment in agricultural capital construction was huge, and it showed a rapid increasing trend; (ii) the investment in agricultural capital construction is characterized by “multi-sector investment, different departments having different investment priorities and investment scale in different periods”; (iii) some investment projects are overlapping between departments, local areas are weak in providing support funds, project construction standard is single, and there are problems of attaching importance to the application, belittling the management, stressing the construction, belittling the maintenance, and serious brain drain; (iv) different departments have accumulated certain experience in long-term exploration. For example, they pay more attention to the refinement and differentiation of projects, focus on the development of targeted poverty alleviation, pay more attention to the “quality” of investment, and pay more attention to the transformation of agricultural production methods. Based on current situations and problems, it came up with recommendations including promoting the integration of funds for investment and project integration, strengthening the personnel cultivation, ensuring simultaneous construction and management of projects, stressing the maintenance after project construction, exploring new modes for project design, management, investment, and financing, and enhancing the support for special investment projects.

description: This paper analyzes the origin of the traditional small-scale peasant economy in China, introduces the development basis of traditional agriculture and the constraints of traditional agricultural development. Then it analyzes the possibility of transformation caused by the change of constraints according to the possibility of resource endowment changes and the possibility of changes in economic foundations and political cultural foundations. And finally based on the analysis of constraints, it is concluded that the development of China’s future needs to focus on small-scale farmers, large-scale planting households, cooperatives and a small number of enterprises, and put forward three paths to developing modern agriculture which are large scale land operation, the professional cooperation of farmers, and the large scale production processes.

Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)

description: Using a hybrid formalism, superstrings on AdS(3) x S(1) are studied in a manifestly supersymmetric manner. The world-sheet fields in this description including superspace coordinates are obtained through a field redefinition from the corresponding ones in the RNS formalism. The physical states are defined with the BRST cohomology as an N=4 topological string theory. The physical spectra for some lower mass levels are investigated. We identify two series of the space-time chiral primaries which have already been obtained from the analysis in the RNS formalism. We find that they are described by the chiral and the vector supermultiplets, but the on-shell physical structure of the latter depends on whether it is massive or massless. The spece-time supersymmetry on this background is extended to the boundary N=2 uperconformal symmetry. We explicitly construct its generators and study how they act on specific supermultiplets.

description: This report updates a 1979 classification system of nonmetro counties, known as the ERS typology, which was designed to provide policy-relevant infomiation about diverse rural conditions to policymakers, public officials, and researchers. The original classification summarized the economic and social conditions existing in nonmetro counties in 1979 into seven county types. Four (farming, manufacturing, mining, and government) reflect dependence on particular economic activities. Three (persistent-poverty. Federal lands, and retirement-destination) reflect other pohcy-relevant themes. Unclassified counties comprise a residual group. This analysis focuses on rural economic and socio-demographic change from 1979 to 1986. Results reflect rural trends of the 1980's-decline in natural resource-based activities, continuing industrial restructuring, employment growth in services, and regional shifts in industrial location.

description: Visual relationship detection, as a challenging task used to find and distinguish the interactions between object pairs in one image, has received much attention recently. In this work, we propose a novel visual relationship detection framework by deeply mining and utilizing relative location of object-pair in every stage of the procedure. In both the stages, relative location information of each object-pair is abstracted and encoded as auxiliary feature to improve the distinguishing capability of object-pairs proposing and predicate recognition, respectively; Moreover, one Gated Graph Neural Network(GGNN) is introduced to mine and measure the relevance of predicates using relative location. With the location-based GGNN, those non-exclusive predicates with similar spatial position can be clustered firstly and then be smoothed with close classification scores, thus the accuracy of top $n$ recall can be increased further. Experiments on two widely used datasets VRD and VG show that, with the deeply mining and exploiting of relative location information, our proposed model significantly outperforms the current state-of-the-art.

description: As a key focus of cartography and terrain analysis, the simplification of a digital elevation model (DEM) is used to preserve the pattern features of the terrain surface while suppressing its details over multiple scales. Statistical filtering and structural analysis methods are commonly used for this process. The structural analysis method performs well in identifying terrain structural edges, while it tends to discard the smooth morphology of a terrain surface. In addition, the filter that aims to reduce noise on a surface may over-smooth the terrain structural edges. Therefore, to preserve both the terrain structural edges and smooth morphology, we propose to combine the techniques of statistical filtering and structural analysis. Specifically, all the critical elevation points and structural edges are first detected from the DEM surface by using the structural analysis method. Then, the iterative guided normal filter is used to smooth the generalized DEM with the guidance of the structure of the original surface. After this process, the terrain structure is retained in the smooth surface of the DEM. The experimental results with a real-world dataset show that our method can inherit the merits of both structural analysis and statistical filter in preserving terrain features for multi-scale DEM representations.

description: We present a systematic, and fully analytic, study of the ratio R_{pA} between the gluon distribution in a nucleus and that in a proton scaled up by the atomic number A. We consider initial conditions of the McLerran-Venugopalan type, and quantum evolution in the Color Glass Condensate, with both fixed and running coupling. We perform an analytic study of the Cronin effect in the initial conditions and point out an interesting difference between saturating effects and twist effects in the nuclear gluon distribution. We show that the distribution of the gluons which make up the condensate in the initial conditions is localized at low momenta, but this particular feature does not survive after the quantum evolution. We demonstrate that the rapid suppression of the ratio R_{pA} in the early stages of the evolution is due to the DGLAP-like evolution of the proton, whose gluon distribution grows much faster than that in the nucleus because of the large separation between the respective saturation momenta. The flattening of the Cronin peak, on the other hand, is due to the evolution of the nucleus. We show that the running coupling effects slow down the evolution, but eventually lead to a stronger suppression in R_{pA} at sufficiently large energies.

Several specific approaches to business assistance are discussed: a focus on small business, industrial targeting, retention and expansion programs, seed and venture capital programs, industrial parks, business incubators, and enterprise zones. The authors stress that the success of any specific business assistance approach will depend upon the context, and that the strength of an overall economic development strategy for a rural community or region is likely to come from the thoughtful combination of several elements, often including some business assistance, rather than the selection of a single "perfect" ingredient.

description: The glass transition remains unclarified in condensed matter physics. Investigating the mechanical properties of glass is challenging because any global deformation that may result in shear rejuvenation requires an astronomical relaxation time. Moreover, it is well known that a glass is heterogeneous and a global perturbation cannot explore local mechanical/transport properties. However, an investigation based on a local probe, i.e. microrheology, may overcome these problems. Here, we establish active microrheology of a bulk metallic glass: a probe particle driven into host medium glass. This is a technique amenable for experimental investigations. We show that upon cooling the microscopic friction exhibits a second-order phase transition; this sheds light on the origin of friction in heterogeneous materials. Further, we provide distinct evidence to demonstrate that a strong relationship exists between the microscopic dynamics of the probe particle and the macroscopic properties of the host medium glass. These findings establish active microrheology as a promising technique for investigating the local properties of bulk metallic glass.

description: We study how we can understand the change of the spectral function and the pole location of the correlation function for sigma at finite temperature, which were previously obtained in the linear sigma model with a resummation technique called optimized perturbation theory. There are two relevant poles in the sigma channel. One pole is the original sigma pole which shows up as a broad peak at zero temperature and becomes lighter as the temperature increases. The behavior is understood from the decreasing of the sigma condensate, which is consistent with the Brown-Rho scaling. The other pole changes from a virtual state to a bound state of pion-pion as the temperature increases which causes the enhancement at the pion-pion threshold. The behavior is understood as the emergence of the pion-pion bound state due to the enhancement of the pion-pion attraction by the induced emission in medium. The latter pole, not the former, eventually degenerates with pion above the critical temperature of the chiral transition. This means that the observable "sigma" changes from the former to the latter pole, which can be interpreted as the level crossing of "sigma" and pion-pion at finite temperature.

description: Each December, college football fans and pundits across America debate which two teams should meet in the NCAA Division I-A National Championship game. The Bowl Championship Series (BCS) standings employed to select the teams invited to this game are intended to provide an unequivocal #1 v. #2 game for the championship; however, this selection process has itself been highly controversial in recent years. The computer algorithms that constitute one part of the BCS standings often act as lightning rods for the controversy, in part because they are inadequately explained to the public. We present an alternative algorithm that is simply explained yet remains effective at ranking the best teams. We define a ranking in terms of biased random walkers on the graph formed by the schedule of games played, with two teams (vertices) connected by an edge if they played each other. Each random walker moves from team to team by selecting a game and "voting" for its winner with probability p, tracing out a never-ending path motivated by the "my team beat your team" argument. We study the statistical properties of a collection of such walkers, relate the rankings to the community structure of the underlying network, and demonstrate the results for recent NCAA Division I-A seasons. We also discuss the algorithm's asymptotic behavior, illustrated with some analytically tractable cases for round-robin tournaments, and discuss possible generalizations.

description: Inhibition is one of the core concepts in Cognitive Psychology. The idea of inhibitory mechanisms actively weakening representations in the human mind has inspired a great number of studies in various research domains. In contrast, Computer Science only recently has begun to consider inhibition as a second basic processing quality beside activation. Here, we review psychological research on inhibition in memory and link the gained insights with the current efforts in Computer Science of incorporating inhibitory principles for optimizing information retrieval in Personal Information Management. Four common aspects guide this review in both domains: 1. The purpose of inhibition to increase processing efficiency. 2. Its relation to activation. 3. Its links to contexts. 4. Its temporariness. In summary, the concept of inhibition has been used by Computer Science for enhancing software in various ways already. Yet, we also identify areas for promising future developments of inhibitory mechanisms, particularly context inhibition.

title: Sexual Motivation and Mate Choice in the Female Smooth Newt, Triturus vulgaris
Creators: name: Hosie, Charlotte Ann
Publisher: name: The Open University
Year: 1992

description: This thesis describes a study of sexual motivation and mate choice in the female smooth newt, Triturus vulgaris. Chapter one introduces the species' natural and life histories and sexual behaviour. It also describes the different approaches (causal and functional) that have been employed and explains why a female perspective has been particularly emphasised.

 Chapter three reports the results of the preliminary study of female sexual motivation which provided the basis for further investigation. Chapter four discusses some of the results of the follow-up study. Female sexual responsiveness was monitored over a complete breeding season. The relationship between inseminations and egg-laying was investigated. This chapter essentially looked at female sexual responsiveness from a functional perspective. It was found to vary greatly, and was affected by egg-laying and time of season.

 Chapter five discusses female sexual responsiveness in the same study reported in Chapter four, but from a causal perspective. Female sexual behaviour was described in detail, behaviour patterns were defined and motivation scores were devised to examine variation over the season. Chapter six examines female mate choice. Aspects of male morphology, spermatophore pick-up and partner familiarity were investigated. Females were found to show discrimination for larger-crested males, but this discrimination varied and was related to sexual motivation. Chapter seven reports an investigation into how females perceive the stimuli presented to them by the male during his display. The relative importance of visual and olfactory stimuli was studied, as well as the effect of the combination of both sets of cues.

 Chapter eight re-examines the value to this area of research of using the different approaches and perspectives employed here and discusses the results of all the experiments performed.

description: Research on harvesting alternative energy sources is of interest to meet human demands for energy while reducing environmental pollution caused by the extensive use of fossil fuels. Thermoelectric materials are a promising technology for converting heat into electricity. Among thermoelectric materials, the binary bismuth telluride system (Bi-Te) is widely used. To produce high-quality Bi-Te systems with low materials consumption, spark plasma sintering (SPS) is commonly applied. Because SPS is a fast low-temperature process, controlling the ratio and crystallization of Bi-Te is critical for effective energy conversion. Here, we investigated the quality of Bi-Te systems formed by SPS compaction of raw powders with an in-depth examination of the oxidation effects on their thermoelectric performance. With increasing measurement temperature (300→420 K), the mechanically mixed sample and a commercial Bi2Te3 alloy (sintered at 533 K) showed differences in Seebeck coefficients (0.245→0.267 and 0.223→0.246 mVK−1, respectively). The alloy sample showed a decreased figure of merit (0.863→0.331) while that of the mechanically mixed sample (0.543→1.671) increased with temperature. This was related to the degree of oxygen impurity in each Bi-Te process based on XPS analysis. This study proposes that the integration of oxygen species to Bi-Te can be considered to maximize the thermoelectric efficiency at the specified temperature.

description: The bachelor thesis deals with the perception of their own lives by populations of homosexually oriented men who are infected with HIV virus, live in the Ustecky region and are registered as an infected persons. It also deals with their perception of social services in the region and social work services. The theoretical part focuses not only on the description of HIV and AIDS in general, the mechanism of the virus, treatment and other specifics of the disease, but also describes homosexuality, its origin and connection with the virus, and the related concept of stigmatization, as it can be concluded that the virus socially stigmatizes those who suffer from it. The empirical part aims to determine the perception of life of gays with HIV in the Ustecky Region through their eyes. In the form of semi-structured interviews, it will therefore deals with their subjective evaluation, opinions and satisfaction from the general level of life, as well as the related issue of stigmatization.

description: α-(BEDT-TTF)2KHg(SCN)4 is considered to be in the charge-density-wave (CDW) state below 8 K. We present new magnetoresistance data suggesting that the material undergoes a series of field-induced CDW (FICDW) transitions at pressures slightly exceeding the critical pressure Pc at which the zero-field CDW state is destroyed. Further, we argue that a novel kind of FICDW transitions, entirely determined by a superposition of the strong Pauli and quantizing orbital effects of magnetic field on the CDW wavevector, arises when the field is strongly tilted towards the conducting layers. These new transitions can take place even in the case of a relatively well nested Fermi surface. Finally we report on the superconducting (SC) state and its coexistence with the CDW in the title compound under quasi-hydrostatic pressure. Below Pc the material is most likely a heterogeneous SC/CDW mixture, with the SC phase persisting down to ambient pressure. The SC onset temperature appears to drastically increase upon entering the SC/CDW coexistence region.
