EVALUATION OF THE INDUCTION OF ARYL HYDROCARBON HYDROXYLASE AND SUBCHRONIC TOXICITY OF SELECTED POLYCHLORINATED DIBENZOFURANS (ENVIRONMENT, EXPOSURE, POLLUTION, TCDD)
Creators: name: Doyle, Elizabeth Ann
Publisher: name: American University
Year: 2023

description: Limited data are available on the subchronic toxicity of chlorinated dibenzofurans (PCDF); estimates of PCDF effects have been made largely by analogy to the structurally similar dioxins. Aryl hydrocarbon hydroxylase (AHH) induction was evaluated for 25 PCDFs. AHH is induced by TCDD. Induction has been suggested as an indicator of the toxicity of polychorinated aromatic hydrocarbons. AHH was induced 2,7,2,3,7,8- and 2,3,4,7,8-CDF at half that of TCDD (strongly). Octa- and 2,8-CDF caused moderate induction. Other PCDFs tested were inactive. Sprague-Dawley rats were given 60 ppb PCDFs in feed for 90 days. PCDFs caused no changes in weight gains or feed intake. Blood parameters and organ weights were unaffected by PCDFs except for decreased corpuscular hemoglobin in females. Total lesions of the liver and kidney increased due to all PCDFs except 1,2,3,4,6,7,9-CDF. Testing of three PCDFs at higher doses confirmed that PCDFs are less toxic than TCDD and elicit different responses. Bile duct and hepatocellular necrosis were the major hepatic lesions observed. All PCDFs caused moderate renal lesions at all doses. Glomerulonephritis, proteinaceous casts and tubular degeneration were the major renal lesions observed.

description: In this class research project, we explored the usage of visual prompts in correct disposal of garbage, paper, recyclables, and food scraps. We focused our project on the distribution of coffee cups and plastic bags in the sorting bins at the Sauder Exchange Café and Forestry bins near Tim Hortons. Accordingly, our research question was “Do prompts such as “no coffee cup” and “no plastic bag” stickers impact coffee cup and plastic bag contamination in the wrong bins?” and we predicted that the percentage of correct throws of coffee cups and plastic bags would improve after applying the stickers on top of the sorting bins. We conducted an experimental groups design, using naturalistic observation to monitor participants. We measured the percentage of correct disposal of coffee cups and plastic bags before and after adding the prompts. In addition, we observed the percentage of correct disposals of all the other bins to see if prompts had an indirect effect on where a participant would throw their disposals. In the end, we found no significant results in our primary research question but we found some significant results in the general disposal.

Sign-graded posets, unimodality of $W$-polynomials and the Charney-Davis Conjecture

description: We generalize the notion of graded posets to what we call sign-graded (labeled) posets. We prove that the $W$-polynomial of a sign-graded poset is symmetric and unimodal. This extends a recent result of Reiner and Welker who proved it for graded posets by associating a simplicial polytopal sphere to each graded poset $P$. By proving that the $W$-polynomials of sign-graded posets has the right sign at -1, we are able to prove the Charney-Davis Conjecture for these spheres (whenever they are flag).

Decoherence, irreversibility and the selection by decoherence of quantum states with definite probabilities
Creators: name: Omnes, Roland
Publisher: name: arXiv
Year: 2003
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: The problem investigated in this paper is einselection, i. e. the selection of mutually exclusive quantum states with definite probabilities through decoherence. Its study is based on a theory of decoherence resulting from the projection method in the quantum theory of irreversible processes, which is general enough for giving reliable predictions. This approach leads to a definition (or redefinition) of the coupling with the environment involving only fluctuations. The range of application of perturbation calculus is then wide, resulting in a rather general master equation. Two distinct cases of decoherence are then found: (i) A ``degenerate'' case (already encountered with solvable models) where decoherence amounts essentially to approximate diagonalization; (ii) A general case where the einselected states are essentially classical. They are mixed states. Their density operators are proportional to microlocal projection operators (or ``quasi projectors'') which were previously introduced in the quantum expression of classical properties. It is found at various places that the main limitation in our understanding of decoherence is the lack of a systematic method for constructing collective observables.

Analysis on Complete Set of Fock States with Explicit Wavefunctions for the Covariant Harmonic Oscillator Problem

description: The earlier treatments of Lorentz covariant harmonic oscillator have brought to light various difficulties, such as reconciling Lorentz symmetry with the full Fock space, and divergence issues with their functional representations. We present here a full solution avoiding those problems. The complete set of Fock states is obtained, together with the corresponding explicit wavefunction and their inner product integrals free from any divergence problem and the Lorentz symmetry fully maintained without additional constraints imposed. By a simple choice of the pseudo-unitary representation of the underlying symmetry group, motivated from the perspective of the Minkowski spacetime as a representation for the Lorentz group, we obtain the natural non-unitary Fock space picture commonly considered though not formulated and presented in the careful details given here. From a direct derivation of the appropriate basis state wavefunctions of the finite-dimensional irreducible representations of the Lorentz symmetry, the relation between the latter and the Fock state wavefunctions is also explicitly shown. Moreover, the full picture including the states with non-positive norm may give consistent physics picture as a version of Lorentz covariant quantum mechanics. Probability interpretation for the usual von Neumann measurements is not a problem as all wavefunctions restricted to a definite value for the `time' variable are just like those of the usual time independent quantum mechanics. A further understanding from a perspective of the dynamics from the symplectic geometry of the phase space is shortly discussed.

The amplitude of mass fluctuations and mass density of the Universe constrained by strong gravitational lensing
Creators: name: Chen, Da-Ming
Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We investigate the linear amplitude of mass fluctuations in the universe, $σ_8$, and the present mass density parameter of the Universe, $Ω_\mathrm{m}$, from the statistical strong gravitational lensing. We use the two populations of lens halos model with fixed cooling mass scale $M_\mathrm{c}=3\times 10^{13}h^{-1}M_{\sun}$ to match the observed lensing probabilities, and leave $σ_8$ or $Ω_\mathrm{m}$ as a free parameter to be constrained by data. Another varying parameter is the equation of state of dark energy $ω$, and its typical values of -1, -2/3, -1/2 and -1/3 are investigated. We find that $σ_8$ is degenerate with $Ω_\mathrm{m}$ in a way similar to that suggested by present day cluster abundance as well as cosmic shear lensing measurements: $σ_8Ω_\mathrm{m}^{0.6}\approx 0.33$ (Bahcall & Bode\cite{bahcall03a} and references therein). However, both $σ_8\leq 0.7$ and $Ω_\mathrm{m}\leq 0.2$ can be safely ruled out, the best value is when $σ_8=1.0$, $Ω_\mathrm{m}=0.3$ and $ω=-1$. This result is different from that obtained by Bahcall & Bode (\cite{bahcall03a}), who gives $σ_8 =0.98\pm 0.1$ and $Ω_m =0.17\pm 0.05$. For $σ_8=1.0$, higher value of $Ω_\mathrm{m}=0.35$ requires $ω=-2/3$ and $Ω_\mathrm{m}=0.40$ requires $ω=-1/2$.

URBAN GROWTH AND FAMILY FARMERS: STRATEGIC RESPONSES (UNITED STATES AGRICULTURE, REGIONAL FOOD PRODUCTION, DIRECT MARKETING, ADAPTIVE FARMING)
Creators: name: Daughdrill, Martha Jean
Publisher: name: American University
Year: 2023

description: Many of the farmers in the Mid-Atlantic region of the United States whose operations are located near metropolitan centers face a special set of survival problems generated in large part by urban expansion. Yet, urban expansion also provides opportunities for the continued existence of farming activity. This study is an exploration of the ways in which fruit, vegetable, and nursery growers near Washington, D.C., perceive and adapt to the rapid changes occurring in the region as urban growth pushes outward. During an eighteen-month period, ethnographic methods, including participant observation and in-depth interviews, were used to gather quantitative and qualitative data. From a diverse sample of growers who choose to grow and sell their products locally, five resources were identified as necessary components for agricultural production and distribution. Access to land, capital, labor, technical information, and markets influences each individual farm operation. The adaptive responses within the resource arena of markets and marketing are of particular significance to growers, especially because of the sociocultural context. Recent marketing innovations in direct retail sales, such as pick-your-own, roadside stands, and farmers' markets, are enabling growers to remain in agriculture. At the same time, these marketing strategies (particularly farmers' markets) are providing important social connections between growers who represent an emerging type of agriculture in the region and the region's urban and suburban population. Economically and socially, markets have proven beneficial to growers and consumers alike, bringing them together in a regional food system.

description: Standards govern the SHOULD and MUST requirements for protocol implementers for interoperability. In case of TCP that carries the bulk of the Internets' traffic, these requirements are defined in RFCs. While it is known that not all optional features are implemented and nonconformance exists, one would assume that TCP implementations at least conform to the minimum set of MUST requirements. In this paper, we use Internet-wide scans to show how Internet hosts and paths conform to these basic requirements. We uncover a non-negligible set of hosts and paths that do not adhere to even basic requirements. For example, we observe hosts that do not correctly handle checksums and cases of middlebox interference for TCP options. We identify hosts that drop packets when the urgent pointer is set or simply crash. Our publicly available results highlight that conformance to even fundamental protocol requirements should not be taken for granted but instead checked regularly.

description: I shall argue that the high Tc problem is the problem of doping into a Mott insulator. Furthermore, the well documented pseudo-gap phenomenon in underdoped cuprates holds the key to understanding this physics. Phase fluctuation alone cannot explain this phenomenon, but there is a clear need to identify a competing state which lives in the vortex core. The staggered flux state is a good candidate for the competing state and experimental tests of these ideas will be discussed.

Inferring the dark matter power spectrum from the Lyman-alpha forest in high-resolution QSO absorption spectra

Year: 2004

description: We use the LUQAS sample (Kim et al. 2004), a set of 27 high-resolution and high signal-to-noise QSO absorption spectra at a median redshift of z=2.25, and the data from Croft et al. (2002) at a median redshift of z=2.72, together with a large suite of high-resolution large box-size hydro-dynamical simulations, to estimate the linear dark matter power spectrum on scales 0.003 s/km < k <0.03 s/km. Our re-analysis of the Croft et al. data agrees well with their results if we assume the same mean optical depth and gas temperature-density relation. The inferred linear dark matter power spectrum at z=2.72 also agrees with that inferred from LUQAS at lower redshift if we assume that the increase of the amplitude is due to gravitational growth between these redshifts. We further argue that the smaller mean optical depth measured from high-resolution spectra is more accurate than the larger value obtained from low-resolution spectra by Press et al. (1993) which Croft et al. used. For the smaller optical depth we obtain a ~ 20% higher value for the rms fluctuation amplitude of the matter density. By combining the amplitude of the matter power spectrum inferred from the Lyman-alpha forest with the amplitude on large scales inferred from measurements of the CMB we obtain constraints on the primordial spectral index n and the normalisation sigma_8. For values of the mean optical depth favoured by high-resolution spectra, the inferred linear power spectrum is consistent with a LambdaCDM model with a scale-free (n=1) primordial power spectrum.

CAREER LADDERS AND PAY EQUITY VIA INTERNAL LABOR MARKET ADJUSTMENTS: A COMPARATIVE ANALYSIS OF THE NEW YORK AND MARYLAND PUBLIC SECTORS (DISCRIMINATION, WOMEN, UNIONS, WAGES, MOBILITY)
Creators: name: Figart, Deborah M.
Publisher: name: American University
Year: 2023

description: Traditional economic approaches to the sex-based wage differential have overlooked the effect that internal labor markets have on women's employment and earnings. This study argues that the factors behind the pay gap are more complex than the average figures indicate. The gap increases over the life cycle because women are on a lower or different occupational ladder than men, or often do not have access to mobility ladders at all. How then do we promote women into higher-level jobs? How do we create occupational and wage hierarchies in the internal labor market for women? This study answers these questions through a comparison of the career ladder structure for female- versus male-dominated occupations in the public sectors of a strong collective bargaining state, New York, and a state with no comprehensive collective bargaining law, Maryland. The hypothesis is that unions can play a major role in creating ladders and allowing women access to higher-level jobs, as they have done for men. Data are from the Equal Employment Opportunity Commission EEO-4 forms for seven aggregated occupations in 1975, 1980, and 1984. Specifically, mobility probability values and mobility probability lines, proxies for the length and strength of a career ladder, are developed to analyze differences by occupation, sex, and state. Numerical, graphical, and econometric analyses demonstrate that: (1) men have significantly better career opportunities than women in both states (expected); (2) the difference in the mobility opportunities between the sexes in the union state is greater than the nonunion state (unexpected), but decreasing over time; yet (3) career opportunities for both men and women in the union state are greater than the nonunion state (expected). It is concluded that unionization benefits women in a two-stage process. In the first stage, absolute economic gains for all employees are made, but the gap between the sexes is intensified. In the second stage, when prior studies demonstrate a shift from a wage to a nonwage emphasis, women can press for strategies such as labor market mobility or job restructuring to narrow the gap between them and their union brothers.

description: Phase-locking governs the phase noise in classical clocks through effects described in precise mathematical terms. We seek here a quantum counterpart of these effects by working in a finite Hilbert space. We use a coprimality condition to define phase-locked quantum states and the corresponding Pegg-Barnett type phase operator. Cyclotomic symmetries in matrix elements are revealed and related to Ramanujan sums in the theory of prime numbers. The employed mathematical procedures also emphasize the isomorphism between algebraic number theory and the theory of quantum entanglement

SEX DIFFERENCES IN AVERSIVE CONDITIONING: A COMPARISON OF WOMEN AT DIFFERENT PHASES OF THE MENSTRUAL CYCLE WITH MEN (PHOBIA, AGORAPHOBIA, GSR)
Creators: name: Hedlund, Mark Alan
Publisher: name: American University
Year: 2023

description: In an effort to evaluate potential sex differences that may be related to the differential incidence of agoraphobia between the sexes, 30 women and 15 men were exposed to an aversive conditioning procedure. Women were tested either premenstrually (within four days prior to menstruation) or intermenstrually (at any time other than seven days before or following menstruation). Skin conductance was the dependent measure in the conditioning procedure. The purpose of the conditioning procedure was disguised. Menstrual phase information was acquired by the administration of a modified Menstrual Distress Questionnaire. This questionnaire administration was represented to women as a separate experiment. Although substantial evidence established the presence of conditioning among all three groups, no differences were found in conditionability between menstrual phases; however, a weak effect was found indicating a sex difference in conditionability. The disparity between the findings of no menstrual phase differences in this study, and the prior research that has found menstrual differences in conditioning may be accounted for by this investigation's adoption of a more stringent definition of conditioning, and the use of deception. The indication that women are more conditionable than men was discussed within the context of the previous literature which has reported a similar sex difference in aversive conditioning. The possibility that sex differences in aversive conditioning might contribute to the higher frequency of phobias among women as compared to men was also discussed.

description: Driven-dissipative kerr lattices with two-photon driving are experimentally relevant systems known to exhibit a symmetry-breaking phase transition, which belongs to the universality class of the thermal Ising model for the parameter regime studied here. In this work, we perform finite-size scaling of this system as it is quenched to the transition and the dynamical critical exponent is found to be compatible with $z\approx2.18$ corresponding with metropolis dynamics in classical simulations. Furthermore, we show that the Liouvillian gap scales with the same exponent, similar to scaling of the Hamiltonian gap at quantum phase transitions in closed systems.

Publisher: name: The University of British Columbia
Year: 2015

description: The purpose of the Eco-Friendly Post-it Note Project is to help determine which Post-it note product is the most sustainable and should be purchased by UBC for use by the staff. Recently, UBC purchased 50 units of the eco-friendly Post-it notes and 331 units of the standard Post-it notes. To determine the sustainability of each of these Post-it products, this report analyzes the paper and adhesives used in the Post-its with regards to its environmental, social and economic impacts. Based on this analysis, this report proposes that UBC switch from buying the eco-friendly product to the standard product. The eco-friendly Post-it notes that are being considered are made with 100% post-consumer paper. The eco-friendly product is option environmentally by saving energy in manufacturing and reducing pollutants. The eco-friendly post-it is the most. On the other hand, there is a significant cost increase to switch all of the standard Post-it notes to the eco-friendly product. For the social indicators we conducted a survey and the results show that there is no preference for which Post-it notes are used. In the end we determined that the significant cost increase outweighed the environmental benefits of switching to the eco-friendly Post-it notes. We recommend that all purchases of Post-it notes be switched to the standard which will cause a significant cost saving that can be used for other more impactful sustainable products.Disclaimer: “UBC SEEDS provides students with the opportunity to share the findings of their studies, as well as their opinions, conclusions and recommendations with the UBC community.

description: In this work, two composite polymer blends, PMMA/SR and PMMA/PUR, reinforced with carbon fibers (CF)were prepared as a suitable material for lower limb prosthetic foot. The tensile properties were measuredexperimentally. The theoretical part of this work deals with calculations of the deformation and dorsiflexion angle.The finite element technique (ANSYS-15) was used to analyze and evaluate the tensile characteristics, represented by total deformation distribution, equivalent stress and equivalent elastic strain. Results showed that the reinforcement has an influence on the measured properties. Composite polymer blends gave optimum experimental, numerical and theoretical results, which indicates that the composite polymer blends are the best option for the lower limb prosthetic foot.

Skin conductance was the dependent measure in the conditioning procedure. The purpose of the conditioning procedure was disguised. Menstrual phase information was acquired by the administration of a modified Menstrual Distress Questionnaire. This questionnaire administration was represented to women as a separate experiment. Although substantial evidence established the presence of conditioning among all three groups, no differences were found in conditionability between menstrual phases; however, a weak effect was found indicating a sex difference in conditionability. The disparity between the findings of no menstrual phase differences in this study, and the prior research that has found menstrual differences in conditioning may be accounted for by this investigation's adoption of a more stringent definition of conditioning, and the use of deception. The indication that women are more conditionable than men was discussed within the context of the previous literature which has reported a similar sex difference in aversive conditioning. The possibility that sex differences in aversive conditioning might contribute to the higher frequency of phobias among women as compared to men was also discussed.

description: In recent years, multi-access edge computing (MEC) is a key enabler for handling the massive expansion of Internet of Things (IoT) applications and services. However, energy consumption of a MEC network depends on volatile tasks that induces risk for energy demand estimations. As an energy supplier, a microgrid can facilitate seamless energy supply. However, the risk associated with energy supply is also increased due to unpredictable energy generation from renewable and non-renewable sources. Especially, the risk of energy shortfall is involved with uncertainties in both energy consumption and generation. In this paper, we study a risk-aware energy scheduling problem for a microgrid-powered MEC network. First, we formulate an optimization problem considering the conditional value-at-risk (CVaR) measurement for both energy consumption and generation, where the objective is to minimize the expected residual of scheduled energy for the MEC networks and we show this problem is an NP-hard problem. Second, we analyze our formulated problem using a multi-agent stochastic game that ensures the joint policy Nash equilibrium, and show the convergence of the proposed model. Third, we derive the solution by applying a multi-agent deep reinforcement learning (MADRL)-based asynchronous advantage actor-critic (A3C) algorithm with shared neural networks. This method mitigates the curse of dimensionality of the state space and chooses the best policy among the agents for the proposed problem. Finally, the experimental results establish a significant performance gain by considering CVaR for high accuracy energy scheduling of the proposed model than both the single and random agent models.

UNETHICAL BEHAVIOR: A MODEL BASED ON PERSONALITY THEORY AND VALIDATED BY BIOGRAPHIC SIMULATION

description: This research quantified the amount of unethical behavior in the federal executive branch. Unethical behavior was partitioned into two categories: convicted, defined as behavior which resulted in a conviction in a court of law, and unconvicted, defined as unethical behavior of a lesser degree. Data for convicted unethical behavior were collected from the national archives. A regression analysis of these data disclosed that convicted unethical behavior in the federal executive branch had a linear relationship of 17 cases per million employees with no significant variance in any administration over the past one hundred years. Data on unconvicted unethical behavior were collected using the Delphi Method with volunteers who were witting to the incidence of unconvicted unethical behavior. The Delphi Method disclosed that the incidence of unconvicted unethical behavior was ninety times greater than that of convicted unethical behavior. It also arrived at a consensus that the most common abuses of unconvicted unethical behavior were incidents involving abuses of resources, information, influence, time, and the acceptance of favors. These data suggested that this type of behavior was rooted within the individual personality and that a continuum existed with unethical behavior and ethical behavior as its poles. All individuals are located somewhere on this continuum. How one moves along this continuum is the analog of ethical/unethical behavior and is related to the dimensions of personality expressed in terms of Gittinger's Theory of Personality. A model of unethical/ethical behavior was formulated by combining Festinger's Theory of Cognitive Dissonance and Gittinger's Theory of Personality with this continuum. A biographic simulation using the personality dimensions of Robert E. Lee and Benedict Arnold was conducted to validate the model. The simulation correctly replicated the ethical behavior of Lee and the unethical behavior of Arnold. The causal factors of unethical behavior as posited appeared to be validated by the biographic simulation. The utility of biographic simulation and the Personality Assessment System in obtaining values relating to specific dimensions of individual personality appear to have been validated also.

description: We study the dynamical response of cold interacting atoms in the Mott insulator phase to a static force. As shown in the experiment by M. Greiner et. al., Nature \textbf{415}, 39 (2002), this response has resonant character, with the main resonance defined by coincidence of Stark energy and on-site interaction energy. We analyse the dynamics of the atomic momentum distribution, which is the quantity measured in the experiment, for near resonant forcing. The momentum distribution is shown to develop a recurring interference pattern, with a recurrence time which we define in the paper.

Rethinking the Properties of the Quark-Gluon Plasma at $T\sim T_c$

description: We argue that although at asymptotically high temperatures the QGP in bulk behaves as a gas of weakly interacting quasiparticles (modulo long-range magnetism), at temperatures up to few times the critical temperature $T_c$ it displays different properties. If the running of the QCD coupling constant continues in the Coulomb phase till the screening length scale, it reaches the strong coupling treshold $α_s(m_D)\sim 1$. As a result, the Coulomb phase supports weakly bound Coulombic s-wave $\bar c c$, light quark and even $gg$ states. The existence of shallow bound states dramatically increases the quasiparticle rescattering at low energies, reducing the viscosity and thereby explaining why heavy ion collisions at RHIC exhibit robust collective phenomena. In conformal gauge theories at finite temperature the Coulomb binding persists further in the strong coupling regime, as found for ${\cal N}=4$ SUSY YM in the Maldacena regime.

title: Understanding developments in computer technology: a pragmatic and synthetic interpretation
Creators: name: Conroy, Peter William
Publisher: name: The Open University

description: This thesis constructs a new concept of technology which it uses to explain developments in computers and their practical application. The need for this reconceptuallsatlon is demonstrated by a survey illustrating the variability and contradictions between existing uses of the term ’technology', in particular their tendency to emphasise either its concrete or abstract attributes. The possibility of using positivist principles as the basis for a comprehensive concept which can synthesis these two orientations is examined and rejected. Instead, the new concept is constructed with ideas drawn from the work of various non-positivist theorists, principally Marx and Foucault. The result is not a definitive list of characteristics, but a description of the relationships in which technology is used and through which it changes. In order to explore the potential of this concept, it is used to develop an understanding of various aspects of computer technology. Firstly, historical events which led to the construction of the first modern computers are described and their interpretation in terms of the synthetic concept of technology contrasted with ones derived from a positivist causal analysis. In its second application to computer technology, the synthetic concept is used to interpret changes in contemporary methods of developing commercial data processing systems. This discussion is then reinforced and expanded through an interpretation of developments in current research into artificial intelligence. Finally some broader social implications of the case being made by the thesis are examined. Limitations in its argument for this purpose are seen to arise both from the methodology adopted and the narrow empirical domain which has been considered. Consequently new directions of research which will further validate its conclusions are identified.
