Nature and Nurture in Dark Matter Halos

description: Cosmological simulations consistently predict specific properties of dark matter halos, but these have not yet led to a physical understanding that is generally accepted. This is especially true for the central regions of these structures. Recently two major themes have emerged. In one, the dark matter halo is primarily a result of the sequential accretion of primordial structure (ie `Nature'); while in the other, dynamical relaxation (ie `Nurture') dominates at least in the central regions. Some relaxation is however required in either mechanism. In this paper we accept the recently established scale-free sub-structure of halos as an essential part of both mechanisms. Consequently; a simple model for the central relaxation based on a self-similar cascade of tidal interactions, is contrasted with a model based on the accretion of adiabatically self-similar, primordial structure. We conclude that a weak form of this relaxation is present in the simulations, but that is normally described as the radial orbit instability.

description: Let $G$ be an abstract Kac-Moody group over a finite field and $\bar{G}$ be the closure of the image of $G$ in the automorphism group of its positive building. We show that if the Dynkin diagram associated to $G$ is irreducible and neither of spherical nor of affine type, then the contraction groups of elements in $\bar{G}$ which are not topologically periodic are not closed. (In those groups there always exist elements which are not topologically periodic.)
Medieval records of Ombersley manor : (rentals and court rolls, 1300-1500)
Creators: name: Scardellato, Gabriele Pietro

description: The history of English rural society in the Middle Ages generally is written on the basis of records produced by manorial lords which register the dues and obligations of tenants as well as changes in holdings, fines and other legal transactions which touch on the lives of the villagers. This thesis is a critical study of the potential uses of a group of such sources for an historical "reconstruction" of medieval rural conditions. The records under review refer to Ombersley, a Midlands manor belonging to the Benedictine abbey of Evesham, and cover the period of the fourteenth and fifteenth century. While by no means complete, they have survived to an extent that a special study of their value and the problems connected with them is warranted. A brief introduction on the geographic and settlement conditions of the manor (Ch. 1) is followed by a survey of the quality and quantity of the collection of Ombersley account rolls, court records and rentals, summarized in a calendar (Ch. 2 and Appendix). Recent works on the "reconstitution" of medieval rural communities have raised a number of questions on the use of such records; the present thesis attempts to focus this discussion to the use and misuse of rentals (surveys). The importance of this type of document in the study of population trends, land distribution and related aspects of manorial life derives from its wealth of detail. However, owing to their seigneurial point of view and "static" character, rentals are not as reliable as often assumed. The problems connected with them are discussed and illustrated by an analysis of two extensive rentals of Ombersley, presented in an annotated tabulation, combining their data with those extracted from court rolls and other manorial records (Ch. 3). These juxtapositions enable us to date these and other surveys correctly and to identify the "careers" of a good number of individuals and families on the manor. Based on the critical evaluation of these interrelated sources, a summary of the major demographic and economic trends is offered for the two centuries under review, including calculations of the manor's population, mortality rate, reproductive capacity and its economic development as reflected in the payment of different seigneurial dues. Bearing in mind some of the common pitfalls of generalization, I plan to use these data as a basis for monographic treatment of social stratification and other details in Ombersley's history.

description: Cyclopropane, also called trimethylene, is an explosive, colourless gas. Cyclopropane is nonirritating to mucous membranes and does not depress respiration. Induction of and emergence from cyclopropane anesthesia are usually rapid and smooth. A mixture of about 5 to 20 percent cyclopropane in oxygen is administered by inhalation. Because of the flammability and expense of cyclopropane, it is usually used in a closed (rebreathing) system, in which an absorbent chemical, such as soda lime, removes exhaled carbon dioxide, and the anesthetic is recirculated.

description: We investigate the agegraphic dark energy models which were recently proposed to explain the dark energy-dominated universe. For this purpose, we calculate their equation of states and squared speeds of sound. We find that the squared speed for agegraphic dark energy is always negative. This means that the perfect fluid for agegraphic dark energy is classically unstable. Furthermore, it is shown that the new agegraphic dark energy model could describe the matter (radiation)-dominated universe in the far past only when the parameter $n$ is chosen to be $n>n_c$, where the critical values are determined to be $n_c=2.6878(2.5137752)$ numerically. It seems that the new agegraphic dark energy model is no better than the holographic dark energy model for the description of the dark energy-dominated universe, even though it resolves the causality problem.

description: An increasing number of researchers support reproducibility by including pointers to and descriptions of datasets, software and methods in their publications. However, scientific articles may be ambiguous, incomplete and difficult to process by automated systems. In this paper we introduce RO-Crate, an open, community-driven, and lightweight approach to packaging research artefacts along with their metadata in a machine readable manner. RO-Crate is based on Schema.org annotations in JSON-LD, aiming to establish best practices to formally describe metadata in an accessible and practical way for their use in a wide variety of situations. An RO-Crate is a structured archive of all the items that contributed to a research outcome, including their identifiers, provenance, relations and annotations. As a general purpose packaging approach for data and their metadata, RO-Crate is used across multiple areas, including bioinformatics, digital humanities and regulatory sciences. By applying "just enough" Linked Data standards, RO-Crate simplifies the process of making research outputs FAIR while also contributes to enhancing research reproducibility.

description: In randomized experiments, treatment and control groups should be roughly the same--balanced--in their distributions of pretreatment variables. But how nearly so? Can descriptive comparisons meaningfully be paired with significance tests? If so, should there be several such tests, one for each pretreatment variable, or should there be a single, omnibus test? Could such a test be engineered to give easily computed $p$-values that are reliable in samples of moderate size, or would simulation be needed for reliable calibration? What new concerns are introduced by random assignment of clusters? Which tests of balance would be optimal? To address these questions, Fisher's randomization inference is applied to the question of balance. Its application suggests the reversal of published conclusions about two studies, one clinical and the other a field experiment in political participation.

description: A new method for efficiently generating an isolated single-cycle attosecond pulse is proposed. It is shown that the ultraviolet (UV) attosecond pulse can be utilized as a robust tool to control the dynamics of electron wave packets (EWPs). By adding a UV attosecond pulse to an infrared (IR) few-cycle pulse at a proper time, only one return of the EWP to the parent ion is selected to effectively contribute to the harmonics, then an isolated two-cycle 130-as pulse with a bandwidth of 45 eV is obtained. After complementing the chirp, an isolated single-cycle attosecond pulse with a duration less than 100 as seems achievable. In addition, the contribution of the quantum trajectories can be selected by adjusting the delay between the IR and UV fields. Using this method, the harmonic and attosecond pulse yields are efficiently enhanced in contrast to the scheme [G. Sansone {\it et al.}, Science {\bf314}, 443 (2006)] using a few-cycle IR pulse in combination with the polarization gating technique.

description: Cyclopropane is a cycloalkane, consisting of three methylene groups linked to each other to form a ring. The small size of the ring creates substantial ring strain in the structure. Cyclopropane itself is mainly of theoretical interest but many of its derivatives are of commercial significance. The unusual structural properties of cyclopropane have spawned many theoretical discussions. One theory invokes σ-aromaticity: the stabilization afforded by delocalization of the six electrons of cyclopropane's three C-C σ bonds. Cyclopropane is highly flammable. However, despite its strain energy it is not substantially more explosive than other alkanes.

description: A simple and commonly employed approximate technique with which one can examine spatially disordered systems when strong electronic correlations are present is based on the use of real-space unrestricted self-consistent Hartree-Fock wave functions. In such an approach the disorder is treated exactly while the correlations are treated approximately. In this report we critique the success of this approximation by making comparisons between such solutions and the exact wave functions for the Anderson-Hubbard model. Due to the sizes of the complete Hilbert spaces for these problems, the comparisons are restricted to small one-dimensional chains, up to ten sites, and a 4x4 two-dimensional cluster, and at 1/2 filling these Hilbert spaces contain about 63,500 and 166 million states, respectively. We have completed these calculations both at and away from 1/2 filling. This approximation is based on a variational approach which minimizes the Hartree-Fock energy, and we have completed comparisons of the exact and Hartree-Fock energies. However, in order to assess the success of this approximation in reproducing ground-state correlations we have completed comparisons of the local charge and spin correlations, including the calculation of the overlap of the Hartree-Fock wave functions with those of the exact solutions. We find that this approximation reproduces the local charge densities to quite a high accuracy, but that the local spin correlations, as represented by < S_i . S_j >, are not as well represented. In addition to these comparisons, we discuss the properties of the spin degrees of freedom in the HF approximation, and where in the disorder-interaction phase diagram such physics may be important.

Li Po : a biographical study
Creators: name: Shih, Feng-Yu
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation is a critical study on the life of the great T'ang poet Li Po (701-62). First, I investigate the controversy about the poet's background and reconstruct a chronology of his life. Then, in the light of the historical reality of his times, I examine the two most important aspects of the poet's life, namely, his political pursuits and his life as a Taoist recluse. On Li Po's background, I endeavor to demonstrate that the poet was in all probability from obscure origins in modern Szechwan. He may have claimed membership in the Lung-hsi Li clan to promote his social status, and have fabricated the story of his family's long exile in Central Asia to explain why he failed to support, ”his" claim with an authoritative pedigree. The chronology presents a general picture of Li Po's life. Besides adopting or revising the findings of previous scholars, I also make special efforts to illuminate some obscure parts of the poet's life, notably the period 727-40. During that period, the poet kept his family at An-chou and then at Nan-yang, but travelled extensively himself to seek his fortune, including visiting Lo-yang and Ch'ang-an. A romantic dream predominated in Li Po's political life. Seeing himself as a born savior and a lofty recluse, the poet wished to fulfill his obligation to the empire with a quick political success and then to live in seclusion. He tried almost all avenues available to become prominent. However, he was not endowed with practical wisdom. His two short periods of political involvement both ended in failure. Li Po's life as a recluse partly resulted from the current idea that the loftiness of the recluse was prized both by society and by the government and, therefore, would lead to eminence. Indeed, romantic as he was, the poet also fervently loved the colorfulness and mysticism of the life of the recluse, which by his time was much blended with the Taoist quest for immortality. When frustrated in his political pursuits, he would turn to Taoist activities for consolation. But he never became a strict Taoist.
Blame, depression and coping in battered women
Creators: name: Porter, Carol Anne
Publisher: name: University of British Columbia
Year: 2010

description: The focus of this study was the interrelation among the causal attributions, affective reactions, and coping effectiveness of battered women. Fifty female residents of a shelter for battered women were interviewed in depth, and shelter counselors rated each woman on a measure of coping effectiveness. Consistent with predictions, both attributions and emotional state were related to coping. The major deviation from the hypothesized relationship, however, was the finding that self-blame attributions were not related to effective coping while another measure, women's perceptions of the degree of contingency between aspects of themselves and their partners' abusive behavior, was highly related to successful adjustment. As predicted, positive emotional state correlated with effective coping. The hypothesized relation between attributions of blame and affective state was not supported. While subjects' perceptions of avoidability were not related to coping as predicted, it was found that both perceived contingency and a decision not to return to the abusive situation were positively correlated with perceptions of the abuse as unavoidable. Finally, several variables distinguished the group of women who returned from those who did not. Those who returned were characterized by negative affect, a tendency to blame their partners, previous departures from the abusive situation, shorter durations of violence than those who did not return, and were more likely to perceive the abuse as avoidable. The concept of perceived contingency and in particular the difference between this measure and self-blame, is discussed at length because it has implications for both theoretical and applied concerns. The absence of a relation between attributions and affect is also discussed in some detail since an attribution-affect link has received strong support in other psychological research. Problems associated with the definition and measurement of coping are discussed, and finally, the implications of the findings for both attribution theory and research and practice in the area of domestic violence are presented.

description: The thermodynamical properties of dark energy are usually investigated with the equation of state $ω=ω_{0}+ω_{1}z$. Recent observations show that our universe is accelerating, and the apparent horizon and the event horizon vary with redshift $z$. When definitions of the temperature and entropy of a black hole are used to the two horizons of the universe, we examine the thermodynamical properties of the universe which is enveloped by the apparent horizon and the event horizon respectively. We show that the first and the second laws of thermodynamics inside the apparent horizon in any redshift are satisfied, while they are broken down inside the event horizon in some redshift. Therefore, the apparent horizon for the universe may be the boundary of thermodynamical equilibrium for the universe like the event horizon for a black hole.

description: A recent modeling study of brightness ratios for CO rotational transitions in gas typical of the diffuse ISM by Liszt found the role of H collisions to be more important than previously assumed. This conclusion was based on quantum scattering calculations using the so-called WKS potential energy surface (PES) which reported a large cross section for the important 0->1 rotational transition. New close-coupling (CC) rigid-rotor calculations for CO(v=0,J=0) excitation by H are performed on four different PESs. Two of the PESs are obtained in this work using state-of-the-art quantum chemistry techniques at the CCSD(T) and MRCI levels of theory. Cross sections for the J=0->1, as well as other odd Delta J, transitions are significantly suppressed compared to even Delta J transitions in thermal energy CC calculations using the CCSD(T) and MRCI surfaces. This is consistent with a expected even Delta J propensity and in contrast to CC calculations using the earlier WKS PES which predict a dominating 0->1 transition. The current results suggest that the original astrophysical assumption that excitation of CO by H_2 dominates the kinetics of CO in diffuse ISM gas is likely to remain valid.

description: Purpose: Silent corticotroph adenoma (SCA) exhibits more tumor aggressiveness features than functioning adenomas (FCA). We aimed to investigate PCSK1N expression in CA and examine if ER stress-induced responses affect cell survival in a corticotroph tumor cell model.

Methods: Clinical and imaging characteristics were recorded in 33 patients with FCA (20 women,11 macroadenomas) and 18 SCA (8 women, all macroadenomas). Gene expression of proopiomelanocortin (POMC), T-box transcription factor 19(TBX19)/TPIT, proprotein convertase subtilisin/kexin type 1(PCSK1)/PC1/3, and its inhibitor PCSK1N, was measured by RT-qPCR in adenoma tissue. Mouse pituitary corticotroph tumor (AtT-20) cells were treated with tanespimycin (17-AAG), a HSP90 chaperone inhibitor, to induce ER stress followed by gene and protein analyses.

Results: POMC, TPIT, and PCSK1 expression were higher, whereas PCSK1N was lower in FCA compared to SCA. PCSK1N correlated with POMC (rs= -0.514, p <0.001), TPIT (rs= -0.386, p = 0.005), PCSK1 (rs= -0.3691, p = 0.008), and tumor largest diameter (rs= 0.645, p <0.001), in all CA. Induction of ER stress by 17-AAG in AtT-20 cells led to a decrease of POMC but an increase of PCSK1N gene expression at 24h. Moreover, a downregulation of cell cycle, apoptosis, and senescence pathways, and alterations in cell adhesion and cytoskeleton were observed at the protein level.

Conclusions: PCSK1N is higher in SCA compared with FCA, and associated with corticotroph cell markers and tumor size. PCSK1N is likely to be part of the adaptive response to ER stress, potentially conferring a survival advantage to the corticotroph tumor cell in conjunction with other proteins.

description: We present a novel scenario for the growth of dust grains in galaxies at high-redshift ($z\sim 6$). In our model, the mechanical feedback from massive star clusters evolving within high-density pre-enriched media allows to pile-up a large amount of matter into massive supershells. If the gas metallicity ($\geq$ Z$_{\odot}$), number density ($\geq 10^6$ cm$^{-3}$) and dust-to-gas mass ratio ($\sim 1/150 \times Z$) within the supershell are sufficiently large, such supershells may become optically thick to the starlight emerging from their host star clusters and even to radiation from the Cosmic Microwave Background (CMB). Based on semi-analytic models, we argue that this mechanism, occurring in the case of massive ($\geq 10^7$ M$_{\odot}$) molecular clouds hosting $\geq 10^6$ M$_{\odot}$ star clusters, allows a large mass of gas and dust to acquire a temperature below that of the CMB, whereupon dust grain growth may occur with ease. In galaxies with total stellar mass $M_{*}$, grain growth within supershells may increase the dust mass by $\sim 10^6$ M$_{\odot}$ $(M_{*}/10^{8}$ M$_{\odot}$).

description: We present an explicit conjecture for the chiral fusion algebra of critical percolation considering Virasoro representations with no enlarged or extended symmetry algebra. The representations we take to generate fusion are countably infinite in number. The ensuing fusion rules are quasi-rational in the sense that the fusion of a finite number of these representations decomposes into a finite direct sum of these representations. The fusion rules are commutative, associative and exhibit an sl(2) structure. They involve representations which we call Kac representations of which some are reducible yet indecomposable representations of rank 1. In particular, the identity of the fusion algebra is a reducible yet indecomposable Kac representation of rank 1. We make detailed comparisons of our fusion rules with the recent results of Eberle-Flohr and Read-Saleur. Notably, in agreement with Eberle-Flohr, we find the appearance of indecomposable representations of rank 3. Our fusion rules are supported by extensive numerical studies of an integrable lattice model of critical percolation. Details of our lattice findings and numerical results will be presented elsewhere.

description: Smartphone technology has drastically improved over the past decade. These improvements have seen the creation of specialized health applications, which offer consumers a range of health-related activities such as tracking and checking symptoms of health conditions or diseases through their smartphones. We term these applications as Symptom Checking apps or simply SymptomCheckers. Due to the sensitive nature of the private data they collect, store and manage, leakage of user information could result in significant consequences. In this paper, we use a combination of techniques from both static and dynamic analysis to detect, trace and categorize security and privacy issues in 36 popular SymptomCheckers on Google Play. Our analyses reveal that SymptomCheckers request a significantly higher number of sensitive permissions and embed a higher number of third-party tracking libraries for targeted advertisements and analytics exploiting the privileged access of the SymptomCheckers in which they exist, as a mean of collecting and sharing critically sensitive data about the user and their device. We find that these are sharing the data that they collect through unencrypted plain text to the third-party advertisers and, in some cases, to malicious domains. The results reveal that the exploitation of SymptomCheckers is present in popular apps, still readily available on Google Play.

description: Theoretical predictions of the magnetic anisotropy of antiferromagnetic materials are demanding due to a lack of experimental techniques which are capable of a direct measurement of this quantity. At the same time it is highly significant due to the use of antiferromagnetic components in magneto-resistive sensor devices where the stability of the antiferromagnet is of upmost relevance. We perform an ab-initio study of the ordered phases of IrMn and IrMn3, the most widely used industrial antiferromagnets. Calculating the form and the strength of the magnetic anisotropy allows the construction of an effective spin model, which is tested against experimental measurements regarding the magnetic ground state and the Neel temperature. Our most important result is the extremely strong second order anisotropy for IrMn3 appearing in its frustrated triangular magnetic ground state, a surprising fact since the ordered L12 phase has a cubic symmetry. We explain this large anisotropy by the fact that cubic symmetry is locally broken for each of the three Mn sub-lattices.

description: Spin squeezing of a nonlinear interaction model with Josephson-like coupling is studied to obtain time scale of maximal squeezing. Based upon two exactly solvable cases for two and three particles, we find that the maximal-squeezing time depends on the level spacing between the ground state and its next neighbor eigenstate.

Taxation and the financial policy of Canadian closely-held corporations
Creators: name: Macnaughton, Alan Robert
Publisher: name: University of British Columbia

description: Closely-held corporations differ from widely-held corporations in that there are only a few shareholders, most or all of whom participate actively in management. This implies that the objective function is the owners' utility rather than profits, and corporate behaviour is influenced by both the corporate and personal income taxes. This dissertation builds a theoretical model of a closely-held corporation based on these features and uses this model to study empirically farmers' decisions to incorporate. The theoretical model determines the financial policy of a closely-held corporation from the static utility maximization problem of its owner. The model differs from previous work in that the set of financial instruments is extended beyond taxable dividends to include owner's salary, in-kind benefits, and the change in loans from the owner. Also, the modelling of the tax system is unusually detailed and includes the special tax provisions applying to incorporated Canadian small businesses . The Kuhn-Tucker conditions for the model show that the quantities of in-kind benefits consumed by the owner will depend on prices which are adjusted for the tax consequences of the goods' purchase. For dividends, salary, and changes in the amount of shareholder's loans, a financial optimum requires that it is not possible to decrease total personal and corporate taxes paid by increasing one financial variable and decreasing another. More specific conclusions are derived from the model in two ways. First, tax rates applying in Ontario in 1980 are substituted in the Kuhn-Tucker conditions to produce graphs showing the optimal financial policy in the more common situations'. Second, linear programming is used to provide numerical examples of optimal financial policies. This information is used to illuminate a number of tax policy issues relating to closely-held corporations. Other chapters discuss the extension of the model to multiple owners, many time periods, and the decision to incorporate. The last issue is studied empirically using a sample of 3,000 Saskatchewan farmers. Probit analysis shows that the probability that a farm will be incorporated is positively related to the farmer's education and the tax savings from incorporation.
