Should the earnings of co-operative associations be made subject to the federal income tax?
Creators: name: Chambers, Edward James Stewart
Publisher: name: University of British Columbia
Year: 2012

description: This thesis attempts to give an equitable and just answer to the problem of subjecting the earnings of co-operative associations to the federal income tax. The first three chapters discuss the nature of a co-operative per se, the development of the co-operative movement in Canada, the financial and business methods of Canadian co-operatives and the effect which the accumulation of tax-free reserves had had upon co-operative plant values. Chapters IV and V trace the Canadian history of the controversy over co-operative income taxation, and explain the particular application of the Income War Tax Act to co-operative associations before the 1946 amendments. The next two chapters examine the recommendations of three government bodies - two in Great Britain and one in Canada - which have wrestled with the question of subjecting co-operative earnings to income taxation. Chapter VIII explains the present Canadian tax law as it applies to co-operatives and compares it to the laws found in Great Britain and certain foreign countries. Chapter IX consists of an examination of the chief arguments advanced by both the advocates of co-operative income taxation and the defenders of co-operatives from such taxation. It will be noted that the problem is dealt with statistically, historically and theoretically. Such a three sided attack is necessary if just conclusions are to be set forth.

description: The capacity to collect fingerprints of individuals in online media has revolutionized the way researchers explore human society. Social systems can be seen as a non-linear superposition of a multitude of complex social networks, where nodes represent individuals and links capture a variety of different social relations. Much emphasis has been put on the network topology of social interactions, however, the multi-dimensional nature of these interactions has largely been ignored in empirical studies, mostly because of lack of data. Here, for the first time, we analyze a complete, multi-relational, large social network of a society consisting of the 300,000 odd players of a massive multiplayer online game. We extract networks of six different types of one-to-one interactions between the players. Three of them carry a positive connotation (friendship, communication, trade), three a negative (enmity, armed aggression, punishment). We first analyze these types of networks as separate entities and find that negative interactions differ from positive interactions by their lower reciprocity, weaker clustering and fatter-tail degree distribution. We then proceed to explore how the inter-dependence of different network types determines the organization of the social system. In particular we study correlations and overlap between different types of links and demonstrate the tendency of individuals to play different roles in different networks. As a demonstration of the power of the approach we present the first empirical large-scale verification of the long-standing structural balance theory, by focusing on the specific multiplex network of friendship and enmity relations.

description: The study of spectral behavior of networks has gained enthusiasm over the last few years. In particular, Random Matrix Theory (RMT) concepts have proven to be useful. In discussing transition from regular behavior to fully chaotic behavior it has been found that an extrapolation formula of the Brody type can be used. In the present paper we analyze the regular to chaotic behavior of Small World (SW) networks using an extension of the Gaussian Orthogonal Ensemble. This RMT ensemble, coined the Deformed Gaussian Orthogonal Ensemble (DGOE), supplies a natural foundation of the Brody formula. SW networks follow GOE statistics till certain range of eigenvalues correlations depending upon the strength of random connections. We show that for these regimes of SW networks where spectral correlations do not follow GOE beyond certain range, DGOE statistics models the correlations very well. The analysis performed in this paper proves the utility of the DGOE in network physics, as much as it has been useful in other physical systems.

description: We show that a diamond shaped periodic network, recently proposed as a model of a spin filter (A. Aharony {\em et al.} \cite{aharon08}) is capable of behaving as a p-type or an n-type semiconductor depending on a suitable choice of the on-site potentials of the atoms occupying the vertices of the lattice, and the strength of the magnetic flux threading each plaquette of the network. A detailed study of the density of states of an infinite network is made together with the conductance of finite sized system to establish the idea.

description: The old problem of a singular, inverse square potential in nonrelativistic quantum mechanics is treated employing a field-theoretic, functional renormalization method. An emergent contact coupling flows to a fixed point or develops a limit cycle depending on the discriminant of its quadratic beta function. We analyze the fixed points in both conformal and non-conformal phases and perform a natural extension of the renormalization group analysis to complex values of the contact coupling. Physical interpretation and motivation for this extension is the presence of an inelastic scattering channel in two-body collisions. We present a geometric description of the complex generalization by considering renormalization group flows on the Riemann sphere. Finally, using bosonization, we find an analytical solution of the extended renormalization group flow equations, constituting the main result of our work.

title: Synchronization and Media Exchange in Large-Scale Caenorhabditis elegans Cultures
Creators: name: Brown, Jason D
Publisher: name: Utah State University
Year: 2009

description: The nematode Caenorhabditis elegans is a model organism for understanding sensory molecules of multicellular organisms. Ovulating hermaphrodites produce putative pheromone(s) that cause male attraction. Because pheromones are produced in such small quantities, adult conditioned-media from large-scale synchronous culture is necessary to analyze these pheromones. Current protocols for culture synchronization have volume constraints that limit large-scale synchronous cultures and current methodology for adult conditioned-media production is impractical.
Modification of Tangential Flow Filtration (TFF) systems was investigated for use as a method to increase the volume limits of bleach egg harvest for C. elegans culture synchronization. Also, an adult retention device built within the culture vessel was investigated to optimize the environment for aseptic conditioned-media production from dense large-scale C. elegans cultures.
During this investigation, we have shown that synchronous C. elegans cultures for adult conditioned-media production can be grown at scales larger than reported before, with potential for further scale up. Our growth methodologies have also yielded denser cultures than previously achieved at large scales. Since rapid bleach harvesting appears to be the bottleneck for large-scale production of synchronous C. elegans cultures, our approach of using modified TFF systems with mesh to retain C. elegans eggs increased the amount of eggs that could be bleach harvested at one time. Using this method we have been able to achieve up to 5x103 synchronous C. elegans per mL at a 50L scale. Since scale-up of TFF is straightforward, our results suggest that the technique reported here can easily be applied to larger scale systems for production of adult conditionedmedia from C. elegans. Further, the adult retention device within the culture vessel can ensure that the whole process remains aseptic.

description: Neuroanatomy is often considered the part of the human anatomy syllabus students find hardest to study. To motivate them and boost their learning, clinical cases and neurosurgical images, mainly DTI tractographies produced using an intraoperative magnetic resonance imaging apparatus (MRI/DTI), were presented and discussed during integrated second-year neuroanatomy, neuroradiology and neurosurgery lectures over the five-year 2007-2012 period. Anonymous questionnaires, rated on the Likert scale, showed that the students appreciated this teaching procedure. The academic performance (exam marks for neuroanatomy) of those who attended all the integrated lectures, was slightly, though significantly higher than for students who attended the lectures only occasionally or not at all (p=0.04). Moreover, significantly better results were obtained at the 2012 national progress test (focusing on morphology) by students who attended the MRI/DTI-assisted lectures, compared to those who did so in part or not at all and compared to the national average. These results were obtained by students attending the second, third and, in particular, the fourth, fifth and sixth year (p≤0.0001) courses during the five above-mentioned academic years. The early study of real medical cases, including the relative surgical and post-operative phases, if illustrated by a good collaborative interdisciplinary team, can help direct the students positively towards their future professional reality, without any extra expense to the university. In conclusion, interactive learning tools, like our intraoperative MRI/DTI, motivate students and enhance their learning of neuroanatomy. Most probably it improves long-term retention, which appears to prove helpful during the clinical phase of their undergraduate careers.

Exact sampling of self-avoiding paths via discrete Schramm-Loewner evolution

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: We present an algorithm, based on the iteration of conformal maps, that produces independent samples of self-avoiding paths in the plane. It is a discrete process approximating radial Schramm-Loewner evolution growing to infinity. We focus on the problem of reproducing the parametrization corresponding to that of lattice models, namely self-avoiding walks on the lattice, and we propose a strategy that gives rise to discrete paths where consecutive points lie an approximately constant distance apart from each other. This new method allows us to tackle two non-trivial features of self-avoiding walks that critically depend on the parametrization: the asphericity of a portion of chain and the correction-to-scaling exponent.

description: The instability and nonlinear evolution of directional ocean waves is investigated numerically by means of simulations of the governing kinetic equation for narrow-band surface waves. Our simulation results reveal the onset of the modulational instability for long-crested wave-trains, which agrees well with recent large-scale experiments in wave-basins, where it was found that narrower directional spectra leads to self-focusing of ocean waves and an enhanced probability of extreme events. We find that the modulational instability is nonlinearly saturated by a broadening of the wave-spectrum, which leads to the stabilization of the water-wave system. Applications of our results to other fields of physics, such as nonlinear optics and plasma physics are discussed.

description: The metabolic syndrome is a cluster of metabolic abnormalities including abdominal obesity, hypertension, altered levels of triglycerides and of cholesterol and high fasting glucose levels (Sohet and Delzenne, 2012). In this study, we hypothesized that melatonin, due to its ability to neutralize a number of toxic reactants, including reactive oxygen species and free radicals (Reiter et al. 2008; Agil et al. 2011), can minimize obesity-related alterations in aorta morphology and vasocostriction in an animal model of obesity (ob/ob mice). The animals were divided in four groups: (i) control lean mice, (ii) control lean mice treated with melatonin, (iii) ob/ob mice and (iv) ob/ob mice treated with melatonin. The melatonin (kindly provided by Chronolife S.r.l.) was added to the drinking water from postnatal week 5 to 13. Compared with the obese mice, melatonin intake was associated with a significant decrease in body weight and water consumption. Histological analysis showed that the aortic wall of ob/ob mice had a high tunica media/lumen ratio and that the elastic fibers in the medial layer appeared disrupted and degraded. Moreover, the aorta of ob/ob mice displayed both a higher degree of collagen accumulation in the tunica media and an elevated expression of endothelin-1, marker of vasoconstriction, respect to the normal aorta. Whereas, the aorta of ob/ob mice treated with melatonin had a lower tunica media/lumen ratio, collagen accumulation and endothelin-1 expression in comparison with untreated ob/ob mice. In conclusion, our results showed that melatonin had no apparent effects on the aorta of lean mice, but its administration in ob/ob mice can lead to a reduction in body weight and can ameliorate aorta histopathological dysfunctions; so melatonin could be an effective tool in the management of obesity-related vascular complications.

description: Vascular endothelial growth factor (VEGF) and its transmembrane receptors VEGFR1 and VEGFR2 play a key role in controlling both physiological and pathological angiogenesis, including vascularization of solid tumours. We have identified a novel and crucial signalling mechanism through which activation of VEGFR2 in human endothelial cells (HUVEC) selectively triggers the intracellular release of calcium from acidic compartments, operated by the second messenger NAADP (nicotinic acid adenine dinucleotide phosphate). Live imaging of calcium fluxes in cells treated with VEGF in the presence of specific inhibitors have shown that 1) VEGF-activated calcium stores are different from IP3 and ryanodine sensitive compartments and are of acidic nature, which strongly indicates the involvement of NAADP signalling 2) NAADP inhibition by its specific antagonist Ned-19 abolishes VEGF-induced calcium response. This inhibition is accompanied by impaired phosphorylation of downstream targets ERK1/2, Akt, eNOS, JNK (but not p38) and results in significant reduction of cell proliferation, migration and capillary-like tube formation in vitro. Interestingly, when the angiogenic response to VEGF was assayed in vivo utilizing Matrigel plugs subcutaneously implanted in mice, Ned-19 was found to dramatically inhibit VEGF-induced angiogenesis. Altogether our data showing that NAADP plays a key role in the control of VEGF-induced angiogenesis could potentially contribute to identify new targets for antiangiogenic therapeutic strategies, a goal to which much scientific effort has long been devoted but still awaiting ultimate success.

title: Alternative Sampling and Analysis Methods for Digital Soil Mapping in Southwestern Utah
Creators: name: Brungard, Colby W
Publisher: name: Utah State University
Year: 2009

description: Digital soil mapping (DSM) relies on quantitative relationships between easily measured environmental covariates and field and laboratory data. We applied innovative sampling and inference techniques to predict the distribution of soil properties, soil attributes, taxonomic classes, and dominant vegetation across a 30,000-ha complex Great Basin landscape in southwestern Utah. This arid rangeland was characterized by rugged topography, diverse vegetation, and intricate geology. Environmental covariates calculated from digital elevation models (DEM) and spectral satellite data were used to represent factors controlling soil development and distribution. We investigated optimal sample size and sampled the environmental covariates using conditioned Latin Hypercube Sampling (cLHS). We demonstrated that cLHS, a type of stratified random sampling, closely approximated the full range of variability of environmental covariates in feature and geographic space with small sample sizes. Site and soil data were collected at 300 locations identified by cLHS. Random forests was used to generate spatial predictions and associated probabilities of site and soil characteristics. Balanced random forests and balanced and weighted random forests were investigated for their use in producing an overall soil map. Overall and class errors (referred to as out-of-bag [OOB] error) were within acceptable levels. Quantitative covariate importance was useful in determining what factors were important for soil distribution. Random forest spatial predictions were evaluated based on the conceptual framework developed during field sampling.

description: We investigate the local regularity of pointed spacetimes, that is, time-oriented Lorentzian manifolds in which a point and a future-oriented, unit timelike vector (an observer) are selected. Our main result covers the class of Einstein vacuum spacetimes. Under curvature and injectivity bounds only, we establish the existence of a local coordinate chart defined in a ball with definite size in which the metric coefficients have optimal regularity. The proof is based on quantitative estimates, on one hand, for a constant mean curvature (CMC) foliation by spacelike hypersurfaces defined locally near the observer and, on the other hand, for the metric in local coordinates that are spatially harmonic in each CMC slice. The results and techniques in this paper should be useful in the context of general relativity for investigating the long-time behavior of solutions to the Einstein equations.

Induced Biochemical osteoporosis: Effects of 1-month calcium–deprived diet on rat bone remodelling with/ without contemporary administration of PTH(1-34)

description: It is known that rats fed calcium-deprived diet develop osteoporosis due to enhanced bone resorption secondary to parathyroid overactivity resulting from nutritional hypocalcemia. Therefore, rats provide a good experimental animal model for studying bone remodelling alterations during biochemical osteoporosis. This preliminary study is performed in 3 month-old Sprague Dawley male rats, divided into 4 groups (5 rats each): 1) base line, 2) normal diet for 4 weeks, 3) calcium-deprived diet for 4 weeks; 4) calcium-deprived diet for 4 weeks plus contemporary administration of PTH(1-34) 40µg/kg/day. Three labels of osteogenesis were performed at 1st , 20th and 27th day of experimental period in order to evaluate bone formation during animal treatment. Histomorphometrical analyses were performed on cortical bone of femoral diaphyses, as well as on trabecular bone of distal femoral metaphyses, both transversely sectioned. The preliminary results showed that at femur mid-diaphyseal level the diet induced a reduction of cortical bone area (even if not significant) with enlargement of the medullary canal due to endosteal resorption, while periosteal neo-deposition is similar in all groups and particularly abundant in those periosteal regions mainly devoted in answering the mechanical demands. PTH(1-34) treatment seems to reduce endosteal resorption only in those surfaces where periosteal mechanical loading are less consistent. Conversely, PTH(1-34) treatment doesn’t seem to affect osteoblast activity. Moreover, in distal femoral metaphyses, diet induced osteoclast activity, with a decrease in the amount of trabecular bone volume, confirming that this architecture is mainly devoted in answering the metabolic demands. The novelty of the proposed model Is the contemporary administration of PTH(1-34) together with calcium deprived diet to evaluate induced-biochemical osteoporosis. This model seems a good starting point for successive studies in order to study bone alterations during unbalanced calcium metabolism frequently occurring in aging and to define time and manner of bone mass recovery.

description: Glioblastoma (GB, grade IV astrocytoma) is highly proliferating, infiltrating, and relapsing. So far, no therapy cures the disease and on average lethality occurs within 2 years from diagnosis. Despite the intimate molecular mechanisms of GB remain unknown, the mammalian Target Of Rapamycin (mTOR) is constantly upregulated within GB and in other astrocytomas. Consistently, mTOR was proposed as a target to cure GB. In fact, the mTOR inhibitor rapamycin was tested in order to prevent the growth of GB in human primary cultures and in mouse xenograft. Cytopathology of GB is highly heterogeneous for the co-existence of various cell types and the occurrence progressive steps in cell differentiation. Remarkably, the non differentiated stem-like cells represent primary GB precursors which initiate the tumor growth. Altered transmission of pathological proteins was recently claimed to underly the growth of GB and its infiltration. These proteins are controlled by the mTOR pathway and spread from cell to cell suggesting a prion-like mechanism in GB. Therefore, in the present study, using the human GB cell line U87MG, we evaluated the effect of a wide range of rapamycin concentrations (between 1 nM to 1 x 103 nM) at 24 h on: cell survival; cell morphology and electrophysiology; cell differentiation and migration; expression of PrP and other prion-like proteins. We found that effects of rapamycin on U87MG are dose-dependent. While high doses (100 nM up to 1000 nM) reduce cell viability, lower rapamycin doses (1nm up to 10 nM) produce cell differentiation consisting of morphological and immunohistochemical changes. Rapamycin promotes a neuronal shape with process elongation and increased cell size. This associates with the loss of the staminal marker nestin while the early neuronal marker betaIII-tubulin increases. At 24 h rapamycin inhibits U87MG cell migration dose-dependently. The neuronal morphology associates with altered intracellular calcium flux but not neuronal electrophysiological properties. Finally, expression of prionoids which we found to be high in baseline conditions was suppressed by rapamycin. This is consistent with our ultrastructural findings which substantiate the dramatic effects induced by mTOR inhibition. Our results suggests pathological cell communication in GB while providing cellular evidence supporting the use of rapamycin as well rapalogs as effective drugs to treat malignant astrocytoma.

description: We discuss the large gap anisotropy found for the A1g (s-wave) state in RPA spin-fluctuation and functional renormalization group calculations and show how the simple arguments leading to isotropic sign-switched s-wave states in these systems need to be supplemented by a consideration of pair scattering within Fermi surface sheets and between the individual electron sheets as well. In addition, accounting for the orbital makeup of the states on the Fermi surface is found to be crucial.

Holonomy of a principal composite bundle connection, non-abelian geometric phases and gauge theory of gravity

description: We show that the holonomy of a connection defined on a principal composite bundle is related by a non-abelian Stokes theorem to the composition of the holonomies associated with the connections of the component bundles of the composite. We apply this formalism to describe the non-abelian geometric phase (when the geometric phase generator does not commute with the dynamical phase generator). We find then an assumption to obtain a new kind of separation between the dynamical and the geometric phases. We also apply this formalism to the gauge theory of gravity in the presence of a Dirac spinor field in order to decompose the holonomy of the Lorentz connection into holonomies of the linear connection and of the Cartan connection.

Statistics of eigenfunctions in open chaotic systems: a perturbative approach

description: We investigate the statistical properties of the complexness parameter which characterizes uniquely complexness (biorthogonality) of resonance eigenstates of open chaotic systems. Specifying to the regime of isolated resonances, we apply the random matrix theory to the effective Hamiltonian formalism and derive analytically the probability distribution of the complexness parameter for two statistical ensembles describing the systems invariant under time reversal. For those with rigid spectra, we consider a Hamiltonian characterized by a picket-fence spectrum without spectral fluctuations. Then, in the more realistic case of a Hamiltonian described by the Gaussian Orthogonal Ensemble, we reveal and discuss the rôle of spectral fluctuations.
