description: It was proposed in [(https://doi.org/10.1103/PhysRevLett.114.145301){Chen et al., Phys. Rev. Lett. $\mathbf{114}$, 145301 (2015)}] that spin-2 chains display an extended critical phase with enhanced SU$(3)$ symmetry. This hypothesis is highly unexpected for a spin-2 system and, as we argue, would imply an unconventional mechanism for symmetry emergence. Yet, the absence of convenient critical points for renormalization group perturbative expansions, allied with the usual difficulty in the convergence of numerical methods in critical or small-gapped phases, renders the verification of this hypothetical SU$(3)$-symmetric phase a non-trivial matter. By tracing parallels with the well-understood phase diagram of spin-1 chains and searching for signatures robust against finite-size effects, we draw criticism on the existence of this phase. We perform non-Abelian density matrix renormalization group studies of multipolar static correlation function, energy spectrum scaling, single-mode approximation, and entanglement spectrum to shed light on the problem. We determine that the hypothetical SU$(3)$ spin-2 phase is, in fact, dominated by ferro-octupolar correlations and also observe a lack of Luttinger-liquid-like behavior in correlation functions that suggests that is perhaps not critical. We further construct an infinite family of spin-$S$ systems with similar ferro-octupolar-dominated quasi-SU$(3)$-like phenomenology; curiously, we note that the spin-3 version of the problem is located in a subspace of exact G$_2$ symmetry, making this a point of interest for search of Fibonacci topological properties in magnetic systems.

An oscillating axion field induces transitions between two quasi-degenerate resonant modes of a superconducting cavity. In two broadband runs optimized for high and low masses, this setup can probe unexplored parameter space for axion-like particles covering fifteen orders of magnitude in mass, including astrophysically long-ranged fuzzy dark matter.

description: Since their discovery twenty years ago, the observed luminosity function of $z\gtrsim6$ quasars has been suspected to be biased by gravitational lensing. Apart from the recent discovery of UHS J0439+1634 at $z\approx6.52$, no other strongly lensed $z\gtrsim6$ quasar has been conclusively identified. The hyperluminous $z\approx6.33$ quasar SDSS J0100+2802, believed to host a supermassive black hole of $\sim10^{10} M_\odot$, has recently been claimed to be lensed by a factor of $\sim450$, which would negate both its extreme luminosity and black hole mass. However, its Ly$α$-transparent proximity zone is the largest known at $z>6$, suggesting an intrinsically extreme ionizing luminosity. Here we show that the lensing hypothesis of $z\gtrsim6$ quasars can be quantitatively constrained by their proximity zones. We first show that our proximity zone analysis can recover the strongly lensed nature of UHS J0439+1634, with an estimated magnification $μ=28.0^{+18.4}_{-11.7}(^{+44.9}_{-18.3})$ at 68% (95%) credibility that is consistent with previously published lensing models. We then show that the large proximity zone of SDSS J0100+2802 rules out lensing magnifications of $μ>4.9$ at 95% probability, and conclusively rule out the proposed $μ>100$ scenario. Future proximity zone analyses of existing $z\gtrsim6$ quasar samples have the potential to identify promising strongly lensed candidates, constrain the distribution of $z\gtrsim6$ quasar lensing, and improve our knowledge of the shape of the intrinsic quasar luminosity function.

Application of chemotactic models to Alzheimer’s disease
Creators: name: Luca, Magdalena
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents the analysis of several chemotactic models developed for pattern formation in biological systems. The project was motivated by the complex interactions between glial cells, cytokines and proteins that cause neuronal death and eventual dementia in Alzheimer's disease. I investigate conditions that lead to periodic patterns and aggregation of glial cells and chemicals, as observed in the senile plaques of Alzheimer's disease. I have examined a hierarchy of one dimensional models, starting with a model in which there is a single chemoattractant inflammatory agent and the microglia cells. Thus, I constructed a minimal partial differential equations model similar to the Keller-Segel model for the chemotaxis of microglia and their involvement in secretion and uptake of various inflammatory factors. Stationary solutions of the system of equations are investigated using a method developed by Schaaf. The linear stability analysis of the system leads to the aggregation condition which can be biologically interpreted. As a result, I suggest possible methods that might affect plaque formation in Alzheimer's disease. Numerical simulations help corroborate theoretical results. A different form of the kinetics function which is part of the Keller-Segel model is suggested. Thus, the limiting kinetics function in the chemoattractant equation incorporates production or removal of the chemical factor by the cells, depending on the model parameters. Also, it limits the sharp increase in the cell density which is well known to occur in this type of a chemotactic model. Finally, a model for chemotaxis of cells in response to a chemoattractant and a chemorepellent is developed to include a greater level of detail. The system is reduced in complexity using quasi-steady state approximations, and explicit solutions for chemical diffusion are found using the Green's function method. The model predicts that local attraction and long range repulsion create periodic pattern formation. Biological interpretations of the linear instability condition lead to suggestions for therapy interventions in Alzheimer's disease. Using real biological parameters available in the literature, I compare and discuss the applicability of this particular model to the pattern formation observed in Alzheimer's disease.

description: The quantum Hall system can be used to study many-body physics owing to its multiple internal electronic degrees of freedom and tunability. While quantum phase transitions have been studied intensively, research on the temperature-induced phase transitions of this system is limited. We measured the pure bulk conductivity of a quantum Hall antiferromagnetic state in bilayer graphene over a wide range of temperatures and revealed the two-step phase transition associated with the breaking of the long-range order and short-range antiferromagnetic order. Our findings are fundamental to understanding electron correlation in quantum Hall systems.
Perturbative Wilson loops from unquenched Monte Carlo simulations at weak couplings

description: Perturbative expansions of several small Wilson loops are computed through next-to-next-to-leading order in unquenched lattice QCD, from Monte Carlo simulations at weak couplings. This approach provides a much simpler alternative to conventional diagrammatic perturbation theory, and is applied here for the first time to full QCD. Two different sets of lattice actions are considered: one set uses the unimproved plaquette gluon action together with the unimproved staggered-quark action; the other set uses the one-loop-improved Symanzik gauge-field action together with the so-called ``asqtad'' improved-staggered quark action. Simulations are also done with different numbers of dynamical fermions. An extensive study of the systematic uncertainties is presented, which demonstrates that the small third-order perturbative component of the observables can be reliably extracted from simulation data. We also investigate the use of the rational hybrid Monte Carlo algorithm for unquenched simulations with unimproved-staggered fermions. Our results are in excellent agreement with diagrammatic perturbation theory, and provide an important cross-check of the perturbation theory input to a recent determination of the strong coupling $α_{\bar{\rm MS}}(M_Z)$ by the HPQCD collaboration.

Multidimensional cut-off technique, odd-dimensional Epstein zeta functions and Casimir energy of massless scalar fields
Creators: name: Edery, Ariel

description: Quantum fluctuations of massless scalar fields represented by quantum fluctuations of the quasiparticle vacuum in a zero-temperature dilute Bose-Einstein condensate may well provide the first experimental arena for measuring the Casimir force of a field other than the electromagnetic field. This would constitute a real Casimir force measurement - due to quantum fluctuations - in contrast to thermal fluctuation effects. We develop a multidimensional cut-off technique for calculating the Casimir energy of massless scalar fields in $d$-dimensional rectangular spaces with $q$ large dimensions and $d-q$ dimensions of length $L$ and generalize the technique to arbitrary lengths. We explicitly evaluate the multidimensional remainder and express it in a form that converges exponentially fast. Together with the compact analytical formulas we derive, the numerical results are exact and easy to obtain. Most importantly, we show that the division between analytical and remainder is not arbitrary but has a natural physical interpretation. The analytical part can be viewed as the sum of individual parallel plate energies and the remainder as an interaction energy. In a separate procedure, via results from number theory, we express some odd-dimensional homogeneous Epstein zeta functions as products of one-dimensional sums plus a tiny remainder and calculate from them the Casimir energy via zeta function regularization.

The Compression of Dark Matter Halos by Baryonic Infall

description: The initial radial density profiles of dark matter halos are laid down by gravitational collapse in hierarchical structure formation scenarios and are subject to further compression as baryons cool and settle to the halo centers. We here describe an explicit implementation of the algorithm, originally developed by Young, to calculate changes to the density profile as the result of adiabatic infall in a spherical halo model. Halos with random motion are more resistant to compression than are those in which random motions are neglected, which is a key weakness of the simple method widely employed. Young's algorithm results in density profiles in excellent agreement with those from N-body simulations. We show how the algorithm may be applied to determine the original uncompressed halos of real galaxies, a step which must be computed with care in order to enable a confrontation with theoretical predictions from theories such as LCDM.

Social Stratification of Women.docx

Subjects: subject: Sociology
subject: FOS: Sociology

description: This analysis is conducted to support my research on three generations of women's mothering experiences in China. Stratifying these three generations of women is difficult due to the huge change in the meaning of ‘class’ in the different historical periods and the significant differences from the normal usage in the west. For the oldest generation, the idea of ‘social status’ is more accurate than ‘class’ to describe how people were stratified at that time. Economic differences were reduced to a very low level (Li, 2010) for the great-grandmothers’ generation and part of the grandmothers’ generation. However, after the Reform and Open Door (1978) policies were gradually implemented across China in the late 1980s and early 1990s, rapid differences in people’s incomes became significant and, for the youngest generation, a more western style of ‘middle-class’ started to emerge. Due to these differences, I use ‘social-and-economic status’, instead of ‘class’, in referring to the social stratification of these women. Also, instead of simply presenting each family or woman in terms of low/middle/high social-economic status, I give a detailed rationale for the varied set of criteria used to stratify these women in their specific historical time which consist of this detailed analysis – the historical stratification of women in China. It is worthwhile to point out again that even though I have tried to recruit women from a range of backgrounds, the aim of sampling is not to be representative of the general or certain populations, but to understand how different social positions impact on mother’s experiences.

After some remarks on the general case, timelike and lightlike totally umbilic submanifolds of Lorentzian manifolds are discussed, along with their physical interpretation in view of general relativity. In particular, the mathematical notion of totally umbilic submanifolds is linked to the notions of photon surfaces and of null strings which have been used in the physics literature.

description: In this paper I will show that it is relatively consistent with the usual axioms of mathematics (ZFC) together with a strong form of the axiom of infinity (the existence of a supercompact cardinal) that the class of uncountable linear orders has a five element basis. In fact such a basis follows from the Proper Forcing Axiom, a strong form of the Baire Category Theorem. The elements are X, omega_1, omega_1^*, C, C^* where X is any suborder of the reals of cardinality aleph_1 and C is any Countryman line. This confirms a longstanding conjecture of Shelah.

description: We present new Large Binocular Telescope, Hubble Space Telescope, and Spitzer Space Telescope data for the failed supernova candidate N6946-BH1. We also report an unsuccessful attempt to detect the candidate with Chandra. The ~300,000 Lsun red supergiant progenitor underwent an outburst in 2009 and has since disappeared in the optical. In the LBT data from May 2008 through October 2019, the upper limit on any increase in the R-band luminosity of the source is 2000 Lsun. HST and Spitzer observations show that the source continued to fade in the near-IR and mid-IR, fading by approximately a factor of 2 between October 2015 and September 2017 to 2900 Lsun at H band (F160W). Models of the spectral energy distribution are inconsistent with a surviving star obscured either by an ongoing wind or dust formed in the transient. The disappearance of N6946-BH1 remains consistent with a failed supernova.

description: The objective of supply chain management (SCM) is to remove time and cost from supply chains, improving profitability and/or competitiveness. It is possible through conceptual advances, utilization of computer hardware and software, and other advances in electronic technology. Business literature is used to define the concept. Most applications and benefits have resulted from alliances between large retailers and large packaged goods vendors. Specific applications of SCM in the produce industry, with emphasis on factors such as perishability and production variability, are discussed. Firm-size implications are important. While small and mid-sized growers may find the cost to be high, the innovation of logistics provided by outside suppliers is an alternative. A third-party provider was interviewed; its approach and services are documented; and industry implications are discussed.

description: Changes in consumer demographic composition, information technology, labor force participation, and time demands of the workplace have created demand as well as opportunities for the food retailing industry to deliver food using new alternative methods. Using a logit analysis, this study analyzes consumers' interest in patronizing four alternative food delivery mechanisms by examining the impacts of various socioeconomic and preference variables on consumers' interest in using these services. Data for the study was obtained via surveys conducted at various locations in New Jersey to gather information on consumers' socioeconomic conditions and their interest in using four different methods of accessing food. Empirical results suggest that younger consumers, individuals with at least college education, and households having a larger food budget are more likely to use these services. Interest in convenience contributes positively while concern over product quality, diversity, and prices negatively affect consumers' interest in using one or more of these services. Gender, employment and marital statuses, and driving distance to nearest supermarket have effects on consumers' interest level for some, but not all, of the alternative food delivery methods analyzed.

description: This paper considers and assesses the concept of social externalities through human interdependence, in relation to the economic analysis of externalities in the tradition of Pigou and Arrow, including the analysis of the commons. It argues that there are limits to economic analysis. Our proposal is to enlarge the perspective and start thinking about a broader framework in which any pattern of influence of an agent or a group of agents over a third party, which is not mediated by any economic, social, or psychological mechanism guaranteeing the alignment of the marginal net private benefit with marginal net social benefit, can be attached the “externality” label and be scrutinized for the likely negative consequences that result from the divergence. These consequences may be significant given the many interactions between the social and economic realms, and the scope for spillovers and feedback loops to emerge. The paper also establishes a tentative and probably incomplete list of possible internalizing mechanisms for externalities under this broader framework, which includes: pricing and monetary incentives; altruism and solidarity; moral norms; reciprocity and mutual monitoring; centralized cooperative decision-making; and merger. There are clear reasons why the pricing mechanism is not appropriate in some cases. A more difficult question to answer is what factors determine which of the mechanisms is the appropriate one to rely on in a given sphere of relations and activities. The object of the paper is to encourage research and contributions from all the relevant disciplines of social sciences on the pervasive human interdependence that the notion of social externalities tries to capture.

description: This paper develops two brand-level demand models, where prices are treated as endogenous, to estimate unilateral market power in a representative product-differentiated oligopolistic food market. The results are estimated using point-of-purchase scanner data and are used to quantify the impact of a private-label brand on the economic performance of national brands. Specifically, our study calculates demand parameter estimates and returns to retailer vertical coordination for the frozen vegetable market - the third largest private-label food and beverage category in the United States, after ice cream and carbonated beverages. Consistent with broader industry trends, empirical evidence suggests that the private-label brand maintained a slight competitive advantage over Birds Eye and Green Giant.

description: The Stieltjes-Wigert polynomials, which correspond to an indeterminate moment problem on the positive half-line, are eigenfunctions of a second order q-difference operator. We consider the orthogonality measures for which the difference operator is symmetric in the corresponding weighted $L^2$-spaces. These measures are exactly the solutions to the q-Pearson equation.In the case of discrete and absolutely continuous measures the difference operator is essentially self-adjoint, and the corresponding spectral decomposition is given explicitly. In particular, we find an orthogonal set of q-Bessel functions complementing the Stieltjes-Wigert polynomials to an orthogonal basis for $L^2(μ)$ when $μ$ is a discrete orthogonality measure solving the q-Pearson equation. To obtain the spectral decomposition of the difference operator in case of an absolutely continuous orthogonality measure we use the results from the discrete case combined with direct integral techniques.

description: In an effort to ease communication between packaged goods manufacturers and retailers, this study investigates food retailers' preferences concerning the various promotional programs used in their stores. Through the use of a mail survey, retail executives from supermarket companies shared their perceptions of 22 specific promotional programs regarding each program's use, effectiveness, and attractiveness for future support. According to retailers, clear and consistent promotional performers include targeted direct mail, shipper displays, in-store coupons, in-ad coupons, and in-store demos and sampling. It is noted, however, that the use and perceived effectiveness of these programs may not always seem consistent. For example, retailers felt that promotions tied to local charities are relatively ineffective for increasing product movement or overall store sales, and yet this promotional tool is used by 92 percent of surveyed retailers. On the other hand, frequent shopper programs received favorable marks regarding program effectiveness, and yet they are not commonly used by retailers in this survey. Ultimately, the value that a retailer places on any given promotion is a function of that promotion's ability to meet stated retail objectives, which may extend beyond any hard sales statistics.

description: Cosmological simulations, as well as mounting evidence from observations, have shown that supermassive black holes play a fundamental role in regulating the formation of stars throughout cosmic time. This has been clearly demonstrated in the case of galaxy clusters in which powerful feedback from the central black hole is preventing the hot intracluster gas from cooling catastrophically, thus reducing the expected star formation rates by orders of magnitude. These conclusions have however been almost entirely based on nearby clusters. Based on new Chandra X-ray observations, we present the first observational evidence for massive, runaway cooling occurring in the absence of supermassive black hole feedback in the high-redshift galaxy cluster SpARCS104922.6+564032.5 ($z=1.709$). The hot intracluster gas appears to be fueling a massive burst of star formation ($\approx900$~M$_\odot$yr$^{-1}$) that is offset by dozens of kpc from the central galaxy. The burst is co-spatial with the coolest intracluster gas but not associated with any galaxy in the cluster. In less than 100 million years, such runaway cooling can form the same amount of stars as in the Milky Way. Intracluster stars are therefore not only produced by tidal stripping and the disruption of cluster galaxies, but can also be produced by runaway cooling of hot intracluster gas at early times. Overall, these observations show the dramatic impact when supermassive black hole feedback fails to operate in clusters. They indicate that in the highest overdensities such as clusters and proto-clusters, runaway cooling may be a new and important mechanism for fueling massive bursts of star formation in the early universe.

description: We implement extensive computer simulations to investigate the hysteresis characteristics in the ordered arrays ($l^{}_x\times l^{}_y$) of magnetic nanoparticles as a function of aspect ratio $A^{}_r=l^{}_y/l^{}_x$, dipolar interaction strength $h^{}_d$, and external magnetic field directions. We have considered the aligned anisotropy case, $α$ is the orientational angle. It provides an elegant en route to unearth the explicit role of anisotropy and dipolar interaction on the hysteresis response in such a versatile system. The superparamagnetic character is dominant with weak dipolar interaction ($h^{}_d\leq0.2$), resulting in the minimal hysteresis loop area. Remarkably, the double-loop hysteresis emerges even with moderate interaction strength ($h^{}_d\approx0.4$), reminiscent of antiferromagnetic coupling. These features are strongly dependent on $α$ and $A^{}_r$. Interestingly, the hysteresis loop area increases with $h^{}_d$, provided $A^{}_r$ is enormous, and the external magnetic field is along the $y$-direction. The coercive field $μ^{}_oH^{}_c$, remanent magnetization $M^{}_r$, and the heat dissipation $E^{}_H$ also depend strongly on these parameters. Irrespective of the external field direction and weak dipolar interaction ($h^{}_d\leq0.4$), there is an increase in $μ^{}_oH^{}_c$ with $h^{}_d$ for a fixed $α$ and $A^{}_r\leq4.0$. The dipolar interaction also elevates $M^{}_r$ as long as $A^{}_r$ is huge and the field is along the $y$-direction. $E^{}_H$ is minimal for negligible and weak dipolar interaction, irrespective of $A^{}_r$, $α$, and the field directions. Notably, the magnetic interaction enhances $E^{}_H$ if $A^{}_r$ is enormous and the magnetic field is along the long axis of the system. These results are beneficial in various applications of interest such as digital data storage, spintronics, etc.

description: The epoch of Cosmic Dawn, when the first stars and galaxies were born, is widely considered the final frontier of observational cosmology today. Mapping the period between Cosmic Dawn and the present-day provides access to more than 90% of the baryonic (normal) matter in the Universe, and unlocks several thousand times more Fourier modes of information than available in today's cosmological surveys. We review the progress in modelling baryonic gas observations as tracers of the cosmological large-scale structure from Cosmic Dawn to the present day. We illustrate how the description of dark matter haloes can be extended to describe baryonic gas abundances and clustering. This innovative approach allows us to fully utilize our current knowledge of astrophysics to constrain cosmological parameters from future observations. Combined with the information content of multi-messenger probes, this will also elucidate the properties of the first supermassive black holes at Cosmic Dawn. We present a host of fascinating implications for constraining physics beyond the $Λ$CDM model, including tests of the theories of inflation and the cosmological principle, the effects of non-standard dark matter, and possible deviations from Einstein's general relativity on the largest scales.

description: The paper discusses how the lean concept could be applied to a food-manufacturing company. The paper first presents the lean concept and value-stream mapping tools. The empirical section discusses how a case company, operating as a contract manufacturer in the food industry, has applied the lean production concept and tools. In the case study, three analysis tools are examined and the structures of demand chains of different customers are presented. The delivery times will decrease and more flexibility will be needed from the contract manufacturer. The case study shows that much movement is possible toward the lean supply chain and partnership-based cooperation. By implementing the lean concept, food companies can increase customer value through cost reduction or through provision of additional value-enhanced services.

description: We present results from a Chandra survey of the nine square degree Bootes field of the NOAO Deep Wide-Field Survey (NDWFS). This XBootes survey consists of 126 separate contiguous ACIS-I observations each of approximately 5000 seconds in duration. These unique Chandra observations allow us to search for large scale structure and to calculate X-ray source statistics o ver a wide, contiguous field of view with arcsecond angular resolution and uniform coverage. Optical spectroscopic follow-up observations and the rich NDWFS data set will allow us to identify and classify these X-ray selected sources. Using wavelet decomposition, we detect 4642 point sources with n $\ge$ 2 counts. In order to keep our detections ~99% reliable, we limit our list to sources with n $\ge$ 4 counts. The full 0.5--7 keV band n $\ge$ 4 count list has 3293 point sources. In addition to the point sources, 43 extended sources have been detected consistent, with the depth of these observations and the number counts of clusters. We present here the X-ray catalog for the XBootes survey, including source positions, X-ray fluxes, hardness ratios and their uncertainties. We calculate and present the differential number of sources per flux densit y interval, $N(S)$, for the point sources.

description: We describe an unambiguous gravitational-wave signature to identify the occurrence of a strong phase transition from hadronic matter to deconfined quark matter in neutron star mergers. Such a phase transition leads to a strong softening of the equation of state and hence to more compact merger remnants compared to purely hadronic models. If a phase transition takes place during merging, this results in a characteristic increase of the dominant postmerger gravitational-wave frequency relative to the tidal deformability characterizing the inspiral phase. By comparing results from different purely hadronic and hybrid models we show that a strong phase transition can be identified from a single, simultaneous measurement of pre- and postmerger gravitational waves. Furthermore, we present new results for hybrid star mergers, which contain quark matter already during the inspiral stage. Also for these systems we find that the postmerger GW frequency is increased compared to purely hadronic models. We thus conclude that also hybrid star mergers with an onset of the hadron-quark phase transition at relatively low densities may lead to the very same characteristic signature of quark deconfinement in the postmerger GW signal as systems undergoing the phase transition during merging.

description: The fast growth of product differentiation affects even the raw food product market and causes substantial price variations. The hedonic price technique is applied to examine raw-egg attributes because of a recent transformation from an undifferentiated to a highly differentiated market. The effects of product attributes, production methods, distribution, and product image on retail egg prices are considered. Results reveal that retail egg prices are influenced by specific product attributes including nutritional characteristics and unconventional production methods. Results provide knowledge useful in the development of marketing strategies and suggest areas for possible involvement of policymakers.

description: This thesis presents mathematical and computational approaches to studying signal transduction pathways. The biology.of cellular signalling is introduced, highlighting the importance of signalling pathways in regulating the processes of cell division and proliferation. A brief history of mathematical approaches to such systems is presented. Two multivariate analysis methods, principal component analysis and clustering, are introduced and applied to both gene expression and simulated protein concentration data. Several recent reverse engineering methods that have been used to study genetic networks are introduced. Finally, a reverse engineering method intended to elucidate the structure of genetic networks is adapted to the study of signal transduction systems.
