Strings with extended non-Abelian gauge interaction
Creators: name: Kopecky, Z.
Publisher: name: arXiv
Year: 2004
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: The new generalization of the gauge interaction for the bosonic strings is found. We consider some quasiequivariant maps from the space of metrics on the worldsheet to the space of $n$-tuples of one- and two-dimensional loops. The two-dimensional case is based on the cylinders interacted with a path space connection. The special 2-gauge string model is formulated using two 1-connections, non-Abelian background symmetric tensor field and non-Abelian 2-form. The branched non-Abelian space-time is the result of our construction.

description: We find a relationship between coefficients of fractional parentage (cfp) obtained on the one hand from the principal parent method and on the other hand from a seniority classification. We apply this to the Redmond recursion formula which relates $n \to n+1$ cfp's to $n-1 \to n$ cfp's where the principal parent classification is used. We transform this to the seniority scheme. Our formula differs from the Redmond formula inasmuch as we have a sum over the possible seniorities for the $n \to n+1$ cfp's, whereas Redmond has only one term.

description: Exchange arrangements among different countries over the world are foundations of the world economy, which generally stand behind the daily economic evolution. As the first study of the world exchange arrangements web (WEAW), we built a bipartite network with countries as one type of nodes and currencies as the other, and found it to have a prominent scale-free feature with a power-law degree distribution. In a further empirical study of the currency section of the WEAW, we calculated the clustering coefficients, average nearest-neighbors degree, and average shortest distance. As an essential economic network, the WEAW is found to be a correlated disassortative network with a hierarchical structure, possessing a more prominent scale-free feature than the world trade web (WTW).

Long-Term Cognitive Impairment Following Mild Traumatic Brain Injury with Loss of Consciousness

description: A small subset of individuals that have experienced mild traumatic brain injury (mTBI) may experience persistent cognitive deficits more than a year following the head injury. Neuroimaging studies reveal structural and functional changes in frontal areas of the brain, exacerbated when loss of consciousness is experienced, and indicate that these changes may be progressive in nature for some people. Social support and social participation have, however, been suggested to confer cognitive reserve - neurocognitive protection against cognitive decline. Analyses were run on Canadian Longitudinal Study on Aging (CLSA) neuropsychological data, consisting of individuals who experienced mTBI with loss of consciousness (n = 536 for less than 1 minute, and n = 435 for unconsciousness between 1 and 20 minutes) more than a year prior, and 13,163 no-head injury comparisons. These same individuals were re-assessed three years later. The results presented in this thesis suggest that at a year or more after a single mTBI with loss of consciousness, a small subset of individuals are more likely to be impaired on prospective memory and other executive functioning tasks, relative to comparisons. In addition, when examined at three-year follow-up, those who experienced mTBI with longer duration of unconsciousness were more likely to exhibit cognitive decline relative to those who experienced less unconsciousness or comparisons. Moreover, greater social participation over the past year, and more perceived social support were predictive of lessened cognitive deterioration in those individuals.

Analysis of cells and matrix in cyclosporine-induced gingival overgrowth
Creators: name: Nouri, Masoumeh
Publisher: name: University of British Columbia
Year: 2009

description: Background and objective: Gingival overgrowth is one of the side effects of cyclosporine A, an immunosuppressant agent. Cyclosporine A is used clinically to counteract rejection following organ transplantation. The aim of the present study was to characterize the tissue changes that occur in gingival tissue in patients receiving this medication, compared to control patients' tissues. -Materials and Methods: Gingival biopsies were taken from 18 kidney transplant patients referred to Labafi hospital in Tehran/ Iran. Periodontal flap approach was a part of the procedure to treat their gingival overgrowth. In order to compare these samples with normal tissues, 12 gingival tissue samples were obtained from healthy individuals in the process of crown lengthening that took part in the school of dentistry in SHB University, Tehran/ Iran. The patients from the two groups were as sex and age-matched as much as possible. In all cases, patients gave informed consent for the use of their tissue samples for research. Tissue collection, fixation, histological and histochemical stainings were performed under the same conditions in both groups. The antibodies utilized for immunohistochemical stainings comprised of 1A4, PCNA, LC2, 2B1 and CD44. These antibodies target α-smooth muscle actin, proliferating cells, c terminal and core of versican and hyaluronan receptors, respectively. -Results: Compared to controls, histological features from gingival overgrowth samples revealed changed retepegs, some degrees of acanthosis, hyperkeratosis and parakeratosis, increased vascularization, and severe inflammatory infiltration. The inflammatory infiltrate included high number of macrophages. Matrix changes included prominent accumulation of glycosaminoglycans (GAGs) and proteoglycans (mainly versican). Conclusion: Both epithelium and connective tissue showed changes in gingival overgrowth samples. Gingival overgrowth tissues showed increased inflammation in which CD44 positive cells (macrophages) predominated. More proliferative activity and changes in retepegs were observed in epithelium. The presence of myofibroblasts was noted in connective tissue. Versican accumulation was also observed in connective tissue, in gingival overgrowth samples. Our studies are consistent with a macrophage-driven accumulation of versican-rich connective tissue, associated with epithelial proliferation in gingival overgrowth, secondary to cyclosporine therapy.

description: Kliauga, de Gorter, and Just (2008) and de Gorter, Drabik, and Just (2010) argue that the United States and the European Union establish the world ethanol and biodiesel prices, respectively. We test these theories using a cointegration analysis and the Vector Error Correction (VEC) model. Weekly price series are analyzed for the major global biofuel producers (European Union, United States, and Brazil) for the period 2002 – 2010. Biofuel policies in both the United States and Brazil appear to play a role in determining the ethanol prices in other countries, thus only partially confirming the previous findings for the U.S. price leadership in the literature. For biodiesel, our results demonstrate that the EU tax exemption and mandate impact the world biodiesel price, thus confirming the European Union’s price leadership.

description: We introduce a world fertilizers model that is capable of producing fertilizer demand projections by crop, by country, by macronutrients, and by year. For each crop, the most relevant countries in terms of production, consumption, or trade are explicitly modeled. The remaining countries are modeled, for each crop, within a regional aggregate. The nutrient coverage includes nitrogen (N), phosphorous (P), and potassium (K). In this report we present the data and procedures used to set up the model as well as the assumptions made. The fertilizer model interacts with the yield equations of the FAPRI-ISU model (Food and Agricultural Policy Research Institute at Iowa State University), and by means of a set of production elasticities, projects each nutrient’s application rate per hectare for each commodity and each country covered by the FAPRI-ISU model. Then, the application rates and the areas projected by FAPRI-ISU are used to obtain projections of fertilizer demand from agriculture on a global scale. With this fertilizer module, policies that directly affect fertilizer markets, such as input taxes or subsidies, quantity use restrictions, and trade restrictions, can now be explicitly formulated and evaluated. The effects of these policies on global agricultural markets and on greenhouse gas emissions can be evaluated with the FAPRI-ISU model and the Greenhouse Gas in Agriculture Simulation Model (GreenAgSiM). Also, any other policy affecting commodity markets such as input and output price shocks, biofuels mandates, and land-use change can now be evaluated with regard to its impacts on the world fertilizer markets.

description: This work is devoted to the theoretical description of the plasticity in crystalline material: mechanisms, processes, methods for studying these processes (and how they affect the samples), the texture formation. The brief review of the software package DAMASK is given. Then, the DAMASK is used to simulate some crystalline heterostructures to study the reorientations due to the substantial tensile plastic deformation. The results are analyzed via the inverse pole figures of the tension axis.

description: We investigate the spin-dependent transport properties of quantum-dot based structures where Kondo correlations dominate the electronic dynamics. The coupling to ferromagnetic leads with parallel magnetizations is known to give rise to nontrivial effects in the local density of states of a single quantum dot. We show that this influence strongly depends on whether charge fluctuations are present or absent in the dot. This result is confirmed with numerical renormalization group calculations and perturbation theory in the on-site interaction. In the Fermi-liquid fixed point, we determine the correlations of the electric current at zero temperature (shot noise) and demonstrate that the Fano factor is suppressed below the Poissonian limit for the symmetric point of the Anderson Hamiltonian even for nonzero lead magnetizations. We discuss possible avenues of future research in this field: coupling to the low energy excitations of the ferromagnets (magnons), extension to double quantum dot systems with interdot antiferromagnetic interaction and effect of spin-polarized currents on higher symmetry Kondo states such as SU(4).

description: We calculate the shape and the velocity of a bubble rising in an infinitely large and closed Hele-Shaw cell using Park and Homsy's boundary condition which accounts for the change of the three dimensional structure in the perimeter zone. We first formulate the problem in the form of a variational problem, and discuss the shape change assuming that the bubble takes elliptic shape. We calculate the shape and the velocity of the bubble as a function of the bubble size, gap distance and the inclination angle of the cell. We show that the bubble is flattened as it rises. This result is in agreement with experiments for large Hele-Shaw cells.

description: I compare the risk attitudes of a large, representative sample of farmers to representative samples of the general population and of non-farm small business owners using a robust survey measure of risk tolerance. I find no difference between farmers and the general population in average risk tolerance while small business owners are significantly more risk tolerant than farmers. If farmers shared the same demographic profile as the general population, farmers would be significantly more risk tolerant while if farmers shared the profile of nonfarm business owners they would have similar risk tolerance.

description: This paper analyses efficiency and total factor productivity (TFP) in Hungarian sugar beet production applying non-parametric frontier techniques. For 2004 and 2005 efficiency and TFP are calculated by Data Envelopment Analysis (DEA) and by a Malmquist index respectively. Between 2004 and 2005 the average technical efficiency was very stable, around 0.80 for CRS efficiency and 0.87 for VRS efficiency, suggesting that in both years farms were similarly clustered towards the frontier. The analysis of returns to scale reveals that during both years half (48%) of the sugar beet growers were operating under increasing returns to scale. In the two analysed years changes occurred between decreasing returns to scale and scale efficient farms, when the first increased from 32% to 37%, while the second decreased from 20% to 15%. In 2004 the highest technical efficiency can be observed in Szerencs district followed by Kaba district and then Szolnok district, while the efficiency rating changed in 2005 when the most efficient district was Kaposvár, followed by Szerencs and Petőháza. Between years TFP increased by 9%. The main reason for the observed TFP increase was technical progress of 8%, while technical efficiency played a limited role in improving the performance of sugar beet production. At the same time there was a clear convergence which can be identified and thus improving efficiency scores among individual holdings. Although in the analysed period TFP increased, our empirical results have revealed pure technical inefficiency. In the first three most efficient sugar beet production districts the technical efficiency decreased while in the two least efficient districts technical efficiency increased and they became more homogenous to the frontier compared to the former three districts in 2005.

description: Since EU accession the Hungarian dairy industry’s domestic market has generally expanded as turnover and consumption have both grown, but this has been increasingly due to cheap imports, while the purchase and sale of domestic products has been decreasing or stagnating (both in the domestic and foreign markets). The growth in imports has cut Hungarian corporations domestic market share to 80%. In Hungary corporate concentration has become even more pronounced with large corporations further strengthening their position and smaller ones further shrinking. Moreover, foreign ownership prevails and has the primary aim of meeting domestic demand. Changes in ownership contribute to the strengthening of vertical integration. Still, in the EU corporate concentration trends also exist. However, in the current fierce competitive market, it is not yet apparent whether non-producer ownership or co-operative ownership is more viable. Therefore the increase in Hungarian owners and ownership of processing plants by (Hungarian) producers does not necessarily signal the end of the crisis, but may in fact still signal decline. Positive aspects are increasing concentration and, from the consumers’ standpoint, cheaper dairy products. Cheaper milk products have put great pressure on milk producers (lower milk prices), and have had a positive effect on consumption trends. Milk drinks and some new milk products have been replaced by products with lower milk content and milk-imitations.

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We derive a new method for initial-state collinear showering in Monte-Carlo event generators which is based on the use of unintegrated parton correlation functions. Combined with a previously derived method for final-state showering, the method solves the problem of treating both the hard scattering and the evolution kernels to be used in arbitrarily non-leading order. Although we only treat collinear showering, so that further extensions are needed for QCD, we have discovered several new results: (1) It is better to generate exact parton kinematics in the hard scattering rather than with the subsequent parton showering, and similarly at each step of the showering. (2) Parton showering is then done conditionally on the exact energy-momentum of the initiating parton. (3) We obtain a factorization for structure functions in terms of parton correlation functions so that parton kinematics can be treated exactly from the beginning. (4) We obtain two factorization properties for parton correlation functions, one in terms of ordinary parton densities and one, suitable for event generation, in terms of parton correlation functions themselves.

description: other Hungarian food industry sectors and also compared to the concentration level in West European countries. In the sector the share of foreign capital is also very low (17%). Because of the low share of foreign capital and relatively small concentration, structural and ownership changes were to be expected, resulting in a more concentrated and competitive sector. The restructuring process involved a number of steps. First of all, Sándor Csányi acquired Délhús and then later acquired Pick Szeged, and in 2005 these two corporations’ sectoral share was about 25%. As for the other two large corporations – R-KO-N and Carnex – in late 2005 the latter weakened significantly causing a loss in market share and the bankruptcy of two companies within its industrial group. Currently the meat sector is undergoing rationalisation of costs and activities, coordination, and an elimination process, all brought on by increasing competition. Pork consumption tends to run counter to the rising standard of living as consumption has been stagnating for years. Domestic production of pork is going down but imports (mainly live pigs) are shooting up. Now a portion of produced pork (mainly carcass meat) can be sold in Hungarian’s export markets at the re-accession level. Even today the elimination process is affecting numerous abattoirs. Changes in ownership structure could hasten the elimination process, leading to a reduction in the large surplus capacities. For example, in 2003 50% of pig slaughtering capacities were used, similar to the capacity used in salami and sausage production.

description: We present an antipodal Vivaldi antenna for broadband double metal waveguide terahertz quantum cascade lasers and frequency combs. Its exponentially curved flare profile results in an adiabatic in-plane mode expansion, producing an improved far-field with a single-lobed beam of (23°x19°) full width half maximum with an octave-spanning bandwidth. The antenna also acts as a wave retarder, rotating the polarization from vertical toward horizontal polarization by a frequency-dependent angle. The laser's emission spectrum and current-voltage characteristics are not affected, as well as frequency comb operation. Measurements agree well with numerical simulations, and the proposed antenna covers a broad spectral range (1.5-4.5 THz).
Down to the nitty gritty : the politics and practice of implementing a vision in Kensington-Cedar Cottage, Vancouver
Creators: name: Slack, Sarah

description: Kensington-Cedar Cottage [KCC] is one of twenty three local areas as defined for planning purposes in the City of Vancouver. It is an area characterized by remarkable social diversity. KCC was one of two local areas to pilot the Community Visions program, a new approach to local area planning employed by the City of Vancouver. The KCC CityPlan Committee is comprised of a group of area residents who work with planners from the City of Vancouver in the implementation of the KCC Community Vision. This research asks in what sense the existence of the KCC CityPlan Committee strengthens community planning by facilitating inclusive citizen participation in decision making about the future of the area. This thesis finds that while the existence of the Committee facilitates active citizen participation in decision making about the future of the area for the relatively small group of people who are involved in its activities, the Committee is not representative of the residents of KCC. The KCC CityPlan Committee facilitates information sharing about planning activities with the wider community; however, the priorities and activities of the Committee and Community Vision Implementation Program do not reflect the needs of many KCC residents who struggle daily with securing adequate and affordable housing, food, childcare, and transportation. This research also finds that the existence of the KCC CityPlan Committee provides opportunities for neighbourhood groups in the area to coordinate at the local area level, build a broad base of support, and find resources for their initiatives. In the relationships created between neighbours, that result in collective action toward inclusion, we can find possibilities for neighbourhoods in which all residents feel they belong. The Community Visions Program does support the activities of some of these neighbourhood level groups, though mainly those concerned with environmental beautification. Exclusion and growing disparity will be a reality in Kensington-Cedar Cottage, unless there is a sustained and active commitment to the goal of inclusion by citizens, community groups, city planners, and politicians. Two actions that would result in more inclusive planning in Kensington- Cedar Cottage are support for initiatives at the neighbourhood level that foster inclusion, and the establishment of meaningful partnerships with community based organizations working with marginalized members of the community.

description: We have used the Very Long Baseline Array (VLBA) to image five radio-quiet quasars (RQQs) at milliarcsecond resolution, at frequencies between 1.4 and 5 GHz. These quasars have typical total flux densities of a few millijansky at gigahertz frequencies, and are compact on arcsecond scales. The VLBA images reveal that four of the quasars are dominated by unresolved radio cores, while the fifth has an apparent two-sided jet. Typical core brightness temperatures range from 10^8 K to at least 10^9 K. The compact radio morphologies and X-ray luminosities of many objects in the RQQ sample seem to indicate classical accretion onto black holes as massive as 10^9 solar masses, with emission physics in many ways similar to their radio-loud counterparts. Therefore, the relatively small amount of radiative energy emerging at radio wavelengths in the RQQs may simply be due to the presence of less powerful radio jets.

Flavor Changing Supersymmetry Interactions in a Supernova

description: We consider for the first time R-parity violating interactions of the Minimal Standard Supersymmetric Model involving neutrinos and quarks (``flavor changing neutral currents'', FCNC's) in the infall stage of stellar collapse. Our considerations extend to other kinds of flavor changing neutrino reactions as well. We examine non-forward neutrino scattering processes on heavy nuclei and free nucleons in the supernova core. This investigation has led to four principal original discoveries/products: (1) first calculation of neutrino flavor changing cross sections for spin one half (e.g. free nucleon) and spin zero nuclear targets; (2) discovery of nuclear mass number squared (A squared) coherent amplification of neutrino-quark FCNC's; (3) analysis of FCNC-induced alteration of electron capture and weak/nuclear equilibrium in the collapsing core; and (4) generalization of the calculated cross sections (mentioned in 1) for the case of hot heavy nuclei to be used in collapse/supernova and neutrino transport simulations. The scattering processes that we consider allow electron neutrinos to change flavor during core collapse, thereby opening holes in the electron neutrino sea, which allows electron capture to proceed and results in a lower core electron fraction. A lower electron fraction implies a lower homologous core mass, a lower shock energy, and a greater nuclear photo-disintegration burden for the shock. In addition, unlike the standard supernova model, the core now could have net muon and/or tau lepton numbers. These effects could be significant even for supersymmetric couplings below current experimental bounds.

description: In this paper, a position and velocity estimation method for robotic manipulators which are affected by constant bounded disturbances is considered. The tracking control problem is formulated as a disturbance rejection problem, with all the unknown parameters and dynamic uncertainties lumped into disturbance. Using adaptive robust extended Kalman filter(AREKF) the movement and velocity of each joint is predicted to use in discontinuous Lyapunov-based controller structure. The parameters of the error dynamics have been validated off-line by real data. Computer simulation results given for a two degree of freedom manipulator demonstrate the efficacy of the improved Kalman Filter by comparing the performance of EKF and improved AREKF. Although it is shown that accurate trajectory tracking can be achieved by using the proposed controller.

description: Optimizing on-sky single-mode fiber (SMF) injection is an essential part of developing precise Doppler spectrometers and new astrophotonics technologies. We installed and tested a prototype SMF injection system at the Large Binocular Telescope (LBT) in April 2016. The fiber injection unit was built as part of the de-risking process for a new instrument named iLocater that will use adaptive optics (AO) to feed a high resolution, near-infrared spectrograph. In this paper we report Y-band SMF coupling measurements for bright, M-type stars. We compare theoretical expectations for delivered Strehl ratio and SMF coupling to experimental results, and evaluate fundamental effects that limit injection efficiency. We find the pupil geometry of the telescope itself limits fiber coupling to a maximum efficiency of rho_tel=0.78. Further analysis shows the individual impact of AO correction, tip-tilt residuals, and static (non-common-path) aberrations contribute coupling coefficients of rho_Strehl=0.33, rho_tip/tilt=0.84, and rho_ncpa=0.8 respectively. Combined, these effects resulted in an average Y-band SMF efficiency of 0.18 for all observations. Finally, we investigate the impact of fiber coupling on radial velocity (RV) precision as a function of stellar apparent magnitude.

description: The loop braid group is the motion group of unknotted oriented circles in $\mathbb{R}^3$. In this paper, we study their representations through the approach inspired by two dimensional topological phases of matter. In principle, the motion of loops in $\mathbb{R}^3$ reduces to the motions of points in a two dimensional sliced plane. We realize this physical picture in terms of braided tensor categories and their braid group representations.

description: We present preliminary results from a coronagraphic survey of young nearby Sun-like stars using the Palomar and Keck adaptive optics systems. We have targeted 251 solar analogs (F5-K5) at 20-160 pc from the Sun, spanning the 3-3000 Myr age range. The youngest (<500 Myr) 100 of these have been imaged with deeper exposures to search for sub-stellar companions. The deep survey is sensitive to brown-dwarf companions at separations >0.5" from their host stars, with sensitivity extending to planetary-mass (5-15 Mjup) objects at wider (>3") separations. Based on the discovery of a number of new low-mass (<0.2 Msun) stellar companions, we infer that their frequency at >20 AU separations (probed via direct imaging) may be greater (12%) than that found from radial velocity surveys probing <4 AU separations (6%; Mazeh et al. 2003). We also report the astrometric confirmation of the first sub-stellar companion from the survey - an L4 brown dwarf at a projected distance of 44 AU from the 500 Myr-old star HD 49197. Based on this detection, we estimate that the frequency of sub-stellar companions to solar-type stars is at least 1%, and possibly of order a few per cent.

description: We present a new method for component separation from multifrequency maps aimed to extract Sunyaev-Zeldovich (SZ) galaxy clusters from Cosmic Microwave Background (CMB) experiments. This method is best suited to recover non--Gaussian, spatially localized and sparse signals. We apply our method on simulated maps of the ACBAR experiment. We find that this method improves the reconstruction of the integrated $y$ parameter by a factor three with respect to the Wiener filter case. Moreover, the scatter associated with the reconstruction is reduced by 30 per cent.

An Analysis of Sampling Effect on the Absolute Stability of Discrete-time Bilateral Teleoperation Systems

description: Absolute stability of discrete-time teleoperation systems can be jeopardized by choosing inappropriate sampling time architecture. A modified structure is presented for the bilateral teleoperation system including continuous-time slave robot, master robot, human operator, and the environment with sampled-data PD-like + dissipation controllers which make the system absolute stable in the presence of the time delay and sampling rates in the communication network. The output position and force signals are quantized with uniform sampling periods. Input-delay approach is used in this paper to convert the sampled-data system to a continuous-time counterpart. The main contribution of this paper is calculating a lower bound on the maximum sampling period as a stability condition. Also, the presented method imposes upper bounds on the damping of robots and notifies the sampling time importance on the transparency and stability of the system. Both simulation and experimental results are performed to show the validity of the proposed conditions and verify the effectiveness of the sampling scheme.
Derivation of a Fractional Cross-Diffusion System as the Limit of a Stochastic Many-Particle System Driven by Lévy Noise

description: In this article a fractional cross-diffusion system is derived as the rigorous many-particle limit of a multi-species system of moderately interacting particles that is driven by Lévy noise. The form of the mutual interaction is motivated by the porous medium equation with fractional potential pressure. Our approach is based on the techniques developed by Oelschläger (1989) and Stevens (2000), in the latter of which the convergence of a regularization of the empirical measure to the solution of a correspondingly regularized macroscopic system is shown. A well-posedness result and the non-negativity of solutions are proved for the regularized macroscopic system, which then yields the same results for the non-regularized fractional cross-diffusion system in the limit.
