description: The low-frequency magneto-optical properties of bilayer Bernal graphene are studied by the tight-binding model with four most important interlayer interactions taken into account. Since the main features of the wave functions are well depicted, the Landau levels can be divided into two groups based on the characteristics of the wave functions. These Landau levels lead to four categories of absorption peaks in the optical absorption spectra. Such absorption peaks own complex optical selection rules and these rules can be reasonably explained by the characteristics of the wave functions. In addition, twin-peak structures, regular frequency-dependent absorption rates and complex field-dependent frequencies are also obtained in this work. The main features of the absorption peaks are very different from those in monolayer graphene and have their origin in the interlayer interactions.

description: Career decisions are not necessarily rational as they depend on an individual’s state of mind. Interests, work values, and career satisfaction are commonly investigated in the career development field, but emotions are ostensibly absent in career theory. The way people understand and interpret their life stories is influenced by unconscious influences such as cognitive schemas and defense mechanisms. Maladaptive schemas are usually unconscious and occur when cognitive and emotional patterns created early in life become rigid, self-defeating, and repetitive. Defense mechanisms also influence subjective reactions and can influence emotional distress, stress management, functioning and quality of life. A survey using a sample of American members of the general public (N = 376) was conducted and measured their maladaptive schemas, defense mechanisms, and career satisfaction. Most cognitive schemas correlated with career adaptabilities. There were many moderate correlations between defense mechanisms and career adaptabilities, especially mature defenses, such as sublimation. This research will inform the psychodynamic theory of career development and practice of career counselling.
Explosions Triggered by Violent Binary-Star Collisions: Application to Eta Carinae and other Eruptive Transients

description: This paper discusses a model where a violent periastron collision of stars in an eccentric binary system induces an eruption or explosion seen as a brief transient source, attributed to LBVs, SN impostors, or other transients. The key ingredient is that an evolved primary increases its photospheric radius on relatively short timescales, to a point where the radius is comparable to or larger than the periastron separation in an eccentric binary. In such a configuration, a violent and sudden collision would ensue, possibly leading to substantial mass ejection instead of a binary merger. Repeated periastral grazings in an eccentric system could quickly escalate to a catastrophic encounter, wherein the companion star actually plunges deep inside the photosphere of a bloated primary during periastron, as a result of the primary star increasing its own radius. This is motivated by the case of $η$ Carinae, where such a collision must have occured if conventional estimates of the present-day orbit are correct, and where brief peaks in the light curve coincide with periastron. Stellar collisions may explain brief recurring LBV outbursts like SN 2000ch and SN 2009ip, and perhaps outbursts from relatively low-mass progenitor stars (collisons are not necessarily the exclusive domain of very luminous stars). Finally, mass ejections induced repeatedly at periastron cause orbital evolution; this may explain the origin of very eccentric colliding-wind Wolf-Rayet binaries such as WR140.

description: In this work we consider the entropy-corrected version of interacting holographic dark energy (HDE), in the non-flat universe enclosed by apparent horizon. Two corrections of entropy so-called logarithmic 'LEC' and power-law 'PLEC' in HDE model with apparent horizon as an IR-cutoff are studied. The ratio of dark matter to dark energy densities $u$, equation of state parameter $w_D$ and deceleration parameter $q$ are obtained. We show that the cosmic coincidence is satisfied for both interacting models. By studying the effect of interaction in EoS parameter, we see that the phantom divide may be crossed and also find that the interacting models can drive an acceleration expansion at the present and future, while in non-interacting case, this expansion can happen only at the early time. The graphs of deceleration parameter for interacting models, show that the present acceleration expansion is preceded by a sufficiently long period deceleration at past. Moreover, the thermodynamical interpretation of interaction between LECHDE and dark matter is described. We obtain a relation between the interaction term of dark components and thermal fluctuation in a non-flat universe, bounded by the apparent horizon. In limiting case, for ordinary HDE, the relation of interaction term versus thermal fluctuation is also calculated.

Mercury's global evolution : elucidating the tectonic, volcanic, and early magnetic field history through observations and numerical modeling
Creators: name: Peterson, Georgia
Publisher: name: University of British Columbia
Year: 2021

description: The MESSENGER mission from 2008-2015 yielded a wealth of information about our innermost planet, Mercury. For the first time, visible images of the entire planet, measurements of topography, global characterization of the gravity and magnetic fields as well as surface composition, were all acquired. From these observations, multiple enigmatic aspects regarding the geological evolution of Mercury emerged: The early evolution was dominated by crustal production and creation of the Intercrater Plains by extensive effusive volcanism covering the planet until ~4.0 billion years ago (Ga). This was followed by spatially localized effusive volcanism until ~3.5 Ga that created the Smooth Plains, by global contraction that resulted in a unique global distribution of thrust-fault related landforms called shortening structures, and an early internally-driven magnetic field at ~4.0-3.5 Ga producing crustal magnetization detectable from orbit. In this thesis, I focus on the origin and driving mechanism(s) of each these observations. First, I constrain and investigate the formation of shortening structures in the Smooth Plains. I compile a new comprehensive database that characterizes the morphology of shortening structures and provide the first statistical analysis of variations in morphological characteristics across the entire planet (Chapter 2). Second, areal strain estimates (Chapter 2), and numerical modelling of the surface morphology of Smooth Plain’s shortening structures to constrain the subsurface fault structure (Chapter 3), both require large compressional stresses. These stresses are attributed mainly to 5-10 km of global contraction due to secular cooling of the planet, rather than to bending stresses from volcanic loading by ~1-4 km of basalt as previously assumed. Lastly, I revisit the thermal evolution of Mercury (Chapter 4) and propose the first self-consistent model that matches the newly-constrained geologic record. I focus on a novel way to incorporate the thermal consequences of magmatism and crustal production to form the Intercrater and Smooth Plains. Here, I show that voluminous crustal production can drive a period of strong mantle cooling that both favors an ancient thermally driven dynamo, 5-10 km of radial contraction of the planet, and crustal production.

description: Climate change is a planetary concern that includes a range of extreme weather events and is linked to serious developments in the future. Is local government aware of these threats? What policies could politicians adopt at the local and/or regional level against Climate Change? This is the main question we are invited to answer. The failure to link the global view of a problem to local factors is beginning to be recognized, and significant research efforts are now underway to link the global to local level (Sami, 2018). We explore how Chinese provinces and municipalities work with the central government to implement climate policy. This paper considers China’s potential role in Climate governance, the foundations and nature of China’s climate change policies and envisions the possibility of a new leader emerging in Eurasia policy making (Stavins, 2020)

description: We investigate an estimator to measure the primordial trispectrum in equilateral type non-Gaussian models such as k-inflation, single field DBI inflation and multi-field DBI inflation models from Cosmic Microwave Background (CMB) anisotropies. The shape of the trispectrum whose amplitude is not constrained by the bispectrum in the context of effective theory of inflation and k-inflation is known to admit a separable form of the estimator for CMB anisotropies. We show that this shape is $87 \%$ correlated with the full quantum trispectrum in single field DBI inflation, while it is $33 \%$ correlated with the one in multi-field DBI inflation when curvature perturbation is originated from purely entropic contribution. This suggests that $g_{\rm NL} ^{equil}$, the amplitude of this particular shape, provides a reasonable measure of the non-Gaussianity from the trispectrum in equilateral non-Gaussian models. We relate model parameters such as the sound speed, $c_s$ and the transfer coefficient from entropy perturbations to the curvature perturbation, $T_{\mathcal{R} S}$ with $g_{\rm NL} ^{equil}$, which enables us to constrain model parameters in these models once $g_{\rm NL}^{equil}$ is measured in WMAP and Planck.

description: The novel coronavirus SARS-CoV-2 emerged in 2019. It spread rapidly around the globe and was declared a pandemic by the World Health Organization on March 11, 2020. To mitigate the unprecedented threat of COVID-19, public health agencies, researchers and pharmaceutical companies launched massive efforts to develop effective vaccines and medical treatments. To buy time and save lives, policymakers issued social distancing, mass gathering and face mask orders while ramping up programs for SARS-CoV-2 testing, contact tracing and isolation. In this dissertation, I developed data-driven mathematical models to evaluate the impacts of different intervention strategies on SARS-CoV-2 disease dynamics at a city-level. Chapter 1 provides a brief introduction and the historical context for the four studies, each of which modeled transmission dynamics and mitigation strategies at different stages of the pandemic. In Chapter 2, I estimated the impacts of various school closure and social distancing measures on local healthcare demands. This analysis supported pandemic decision making in Austin, Texas, including the local shelter-in-place order enacted on March 24, 2020. In Chapter 3, I modeled the impacts of relaxing social distancing orders following the initial stay-home orders across the US. For this study, I calibrated the transmission rate in my model based on hospitalization data from the city of Austin and estimated the impacts of cocooning (i.e., sheltering) high-risk individuals as measures relaxed. In Chapter 4, I examined the potential impacts of testing, contact tracing, and case isolation on disease transmission. Using data from a test-trace program jointly administered by Austin Public Health and the University of Texas, I evaluated the relative importance of testing and tracing speed and capacity and found that available resources are insufficient to slow transmission, particularly during times when the virus is spreading rapidly. In Chapter 5, I developed a model to compare SARS-CoV-2 vaccination strategies, that incorporates published efficacy estimates for the Moderna and Pfizer-BioNTech vaccines that received Emergency Use Approval in the US in late 2020. I evaluated the impacts of the timing of the vaccine rollout, the prioritization of vaccines to risk groups and age groups, rates of uptake, and single-dose versus two-dose strategies. Chapter 6 discusses the public health impacts, limitations, and lessons learned from the studies presented in Chapters 2-5. The research presented in this dissertation elucidated SARS-CoV-2 transmission dynamics and effective mitigation strategies at multiple stages of the COVID-19 pandemic and supported decision making by Austin, Texas and the US Centers for Disease Control and Prevention.

Sense of belonging

description: No studies about undecided and exploratory students have focused on sense of belonging. In addition, few of these studies feature or spotlight the student voice. My dissertation fills this gap by purposefully investigating exploratory students and experiences and how they develop or do not develop sense of belonging at a four-year institution. The study uses a case study design with photo elicitation methods to identify and understand this unique case, exploratory students and their sense of belonging (Merriam & Tisdell, 2015; Stake, 1995; Yin, 2017). The research questions are: 1. How do exploratory students describe how they navigate the university? 2. What do they perceive impacting their experiences at this university? 3. Where do they experience or not experience a sense of belonging associated with the university? I interviewed 13 first, second, and third-year exploratory or undecided students in a series of two interviews. These students defined exploratory as an active, positive approach to discovering your interests, while being undecided was associated with stigma and a sense of being stuck. They shared that they encountered common supports at the institution, like the positive messaging and resources of the School of Undergraduate Studies (UGS), the knowledge and care of their academic advisors, and strong positive relationships with peers and faculty built through clubs, organizations, and courses. They also encountered barriers like the COVID-19 pandemic, the complexity of the major change process, and restrictions on introductory courses in some colleges. Returning students seemed to experience greater sense of belonging, recalling their memories of UT prior to the pandemic, while first-year students seemed to experience a lower sense of belonging, as many of these students were unable to visit campus and more acutely felt the impacts of COVID-19 and remote courses. Key recommendations for practitioners include moving from undecided to exploratory in university language, addressing the stigma of the term “undecided” and embracing the possibilities of “exploratory,” creating simple and clear major change processes, and investing in specific staff and resources designed to support exploratory students. Key recommendations for future research include investigating the impacts of institutional context on sense of belonging and student retention and persistence at a variety of institutions, learning more about sense of belonging for exploratory students’ post-pandemic, especially focusing on underrepresented exploratory students, investigating how programs or organizations actively work to destigmatize being exploratory on college campuses, developing a photovoice study (Latz, 2017) where exploratory students set the research agenda and identify their unique areas of concern, and explicitly focusing on staff impacts when investigating sense of belonging.

description: The statistical mechanics of self-gravitating systems has not been well understood, and still remains an open question so far. In a previous study by Kang & He, we showed that the fluid approximation may give a clue to further investigate this problem. In fact, there are indeed many dynamical similarities between self-gravitating and fluid systems. Based on a fluid-like entropy, that work explained successfully the outer density profiles of dark matter halos, but there left some drawbacks with the calculation concerning extremizing process of the entropy. In the current paper, with the improved extremizing calculation -- including an additional differential constraint of dynamical equilibrium and without any other assumptions, we confirm that statistical-mechanical methods can give a density profile with finite mass and finite energy. Moreover, this density profile is also consistent with the observational surface brightness of the elliptical galaxy NGC 3379. In our methods, the density profile is derived from the equation of state, which is obtained from entropy principle but does not correspond to the maximum entropy of the system. Finally, we suggest an alternative entropy form, a hybrid of Boltzmann-Gibbs and Tsallis entropy, whose global maximum may give rise to this equation of state.

Mass distributions of stars and cores in young groups and clusters

description: We investigate the relation of the stellar initial mass function (IMF) and the dense core mass function (CMF), using stellar masses and positions in 14 well-studied young groups. Initial column density maps are computed by replacing each star with a model initial core having the same star formation efficiency (SFE). For each group the SFE, core model, and observational resolution are varied to produce a realistic range of initial maps. A clumpfinding algorithm parses each initial map into derived cores, derived core masses, and a derived CMF. The main result is that projected blending of initial cores causes derived cores to be too few and too massive. The number of derived cores is fewer than the number of initial cores by a mean factor 1.4 in sparse groups and 5 in crowded groups. The mass at the peak of the derived CMF exceeds the mass at the peak of the initial CMF by a mean factor 1.0 in sparse groups and 12.1 in crowded groups. These results imply that in crowded young groups and clusters, the mass distribution of observed cores may not reliably predict the mass distribution of protostars which will form in those cores.

description: The Atacama Pathfinder Experiment (APEX) 12m telescope was used to observe the N=1-0, J=0-1 ground state transitions of OH+ at 909.1588 GHz with the CHAMP+ heterodyne array receiver. Two blended hyperfine structure transitions were detected in absorption against the strong continuum source Sagittarius B2(M) and in several pixels offset by 18". Both, absorption from Galactic center gas as well as absorption from diffuse clouds in intervening spiral arms in a velocity range from -116 to 38.5 km/s is observed. The total OH+ column density of absorbing gas is 2.4 \times 10^15 cm-2. A column density local to Sgr B2(M) of 2.6 \times 10^14 cm-2 is found. On the intervening line-of-sight the column density per unit velocity interval are in the range from 1 to 40 \times 10^12 cm-2/(km/s). OH+ is found to be on average more abundant than other hydrides such as SH+ and CH+. Abundance ratios of OH and atomic oxygen to OH+ are found to be in the range of 10^1-2 and 10^3-4, respectively. The detected absorption of a continuous velocity range on the line-of-sight shows OH+ to be an abundant component of diffuse clouds.

Interactive Learning-Based Realizability for Heyting Arithmetic with EM1

description: We apply to the semantics of Arithmetic the idea of ``finite approximation'' used to provide computational interpretations of Herbrand's Theorem, and we interpret classical proofs as constructive proofs (with constructive rules for $\vee, \exists$) over a suitable structure $\StructureN$ for the language of natural numbers and maps of Gödel's system $\SystemT$. We introduce a new Realizability semantics we call ``Interactive learning-based Realizability'', for Heyting Arithmetic plus $\EM_1$ (Excluded middle axiom restricted to $Σ^0_1$ formulas). Individuals of $\StructureN$ evolve with time, and realizers may ``interact'' with them, by influencing their evolution. We build our semantics over Avigad's fixed point result, but the same semantics may be defined over different constructive interpretations of classical arithmetic (Berardi and de' Liguoro use continuations). Our notion of realizability extends intuitionistic realizability and differs from it only in the atomic case: we interpret atomic realizers as ``learning agents''.
Bound by reconciliation? : social criticism, treaty, and decolonization
Creators: name: Snelgrove, Corey
Publisher: name: University of British Columbia
Year: 2021

description: Through a survey of the politics of reconciliation in Canada and as a concept within political thought, I reconstruct a social-theoretical approach to reconciliation that asks not ‘how can we be reconciled?’ but ‘is reconciliation possible in this society?’ This calls into question the presumption that reconciliation is possible and clarifies Indigenous critiques of reconciliation as social criticism. A social critique of reconciliation is important for it politicizes depoliticized practices, institutions, and social relations that renders our form of interdependence unfree and reveals the contradictions and antagonisms within a settler colonial society that furnishes the motivation for solidarity needed for an emancipatory politics that aims to give interdependence a free form. The presumption of reconciliation has also ‘bound’ approaches to criticism and treaty interpretation. Rather than reading Indigenous treaty visions as a form of immanent critique that demands a change in social relations, treaty is read as a form of internal criticism that in appealing to the gap between Canadian norms and practices seeks to restore the community’s moral standing. This downplays that the institutionalization of the norm of self-determination in Canada has been limited to white settler self-rule while the ends of this political association are constrained by anthropocentric and capitalist social relations. Because of this, self-determination needs to be transformed not extended; treaty represents more critical innovation than the realization of underlying potentials of Canadian norms and institutions. I conclude by returning to the political economy of reconciliation as revealing a shared yet differently experienced crisis of social reproduction caused by the indirect social relations of capitalist societies where needs are subordinated to profit, and that treaty represents an answer to this problem because it aims to transform an unfree form of interdependence into a free one keyed to the flourishing of human and non-human relations. Politically, this requires reading treaty less through the politics of reconciliation and more through the framework of articulation: the treaty partner is not given but must be made. Ultimately I argue that the danger of recuperations of reconciliation – and the presumption of its possibility – is that it downplays the politics of decolonization.

description: This paper introduces a notion of regularity (or irregularity) of the point at infinity for the unbounded open subset of $\rr^{N}$ concerning second order uniformly elliptic equations with bounded and measurable coefficients, according as whether the A-harmonic measure of the point at infinity is zero (or positive). A necessary and sufficient condition for the existence of a unique bounded solution to the Dirichlet problem in an arbitrary open set of $\rr^{N}, N\ge 3$ is established in terms of the Wiener test for the regularity of the point at infinity. It coincides with the Wiener test for the regularity of the point at infinity in the case of Laplace equation. From the topological point of view, the Wiener test at infinity presents thinness criteria of sets near infinity in fine topology. Precisely, the open set is a deleted neigborhood of the point at infinity in fine topology if and only if infinity is irregular.

description: We demonstrate that a Quark-Gluon Plasma (QGP) with a dilute admixture of heavy quarks has, in general, a lower speed of sound than a "pure" QGP without effects from heavy flavors. The change in the speed of sound is sensitive to the details of the theory, making the hydrodynamic response to "flavoring" a sensitive probe of the underlying microscopic dynamics. We suggest that this effect may be measured in ultrarelativistic heavy ion collisions by relating the event-by-event number of charm quarks to flow observables such as the average transverse momentum.

description: We show that scalar, 0-form, Galileon actions --models whose field equations contain only second derivatives-- can be generalized to arbitrary even p-forms. More generally, they need not even depend on a single form, but may involve mixed p combinations, including equal p multiplets, where odd p-fields are also permitted: We construct, for given dimension D, general actions depending on scalars, vectors and higher p-form field strengths, whose field equations are of exactly second derivative order. We also discuss and illustrate their curved-space generalizations, especially the delicate non-minimal couplings required to maintain this order. Concrete examples of pure and mixed actions, field equations and their curved space extensions are presented.

description: Ultrafast time-resolved differential reflectivity of Bi2Se3 crystals is studied using optical pump-probe spectroscopy. Three distinct relaxation processes are found to contribute to the initial transient reflectivity changes. The deduced relaxation timescale and the sign of the reflectivity change suggest that electron-phonon interactions and defect-induced charge trapping are the underlying mechanisms for the three processes. After the crystal is exposed to air, the relative strength of these processes is altered and becomes strongly dependent on the excitation photon energy.

description: The AdS/CFT correspondence in principle gives a new approach to deep inelastic scattering as formulated by Polchinski and Strassler. Subsequently Brower, Polchinski, Strassler and Tan (BPST) computed the strong coupling kernel for the vacuum (or Pomeron) contribution to total cross sections. By identifying deep inelastic scattering with virtual photon total cross section, this allows a self consistent description at small-$x$ where the dominant contribution is the vacuum exchange process. Here we formulate this contribution and compare it with HERA small-$x$ DIS scattering data. We find that the BPST kernel along with a very simple local approximation to the proton and current "wave functions" gives a remarkably good fit not only at large $Q^2$ dominated by conformal symmetry but also extends to small $Q^2$, supplemented by a hard-wall cut-off of the AdS in the IR. We suggest that this is a useful phenomenological parametrization with implications for other diffractive processes, such as double diffractive Higgs production.

description: We present a method for phase and number squeezing in two-mode Bose systems using dissipation. The effectiveness of this method is demonstrated by considering cold Bose gases trapped in a double-well potential. The extension of our formalism to an optical lattice gives control of the phase boundaries of the steady-state phase diagram, and we discover a new phase characterized by a non-zero condensate fraction and thermal-like particle-number statistics. We also show how to perform amplitude squeezing in a single-mode system using dissipation.

description: Conventional particle theories such as the Standard Model have a number of freely adjustable coupling constants and mass parameters, depending on the symmetry algebra of the local gauge group and the representations chosen for the spinor and scalar fields. There seems to be no physical principle to determine these parameters as long as they stay within certain domains dictated by the renormalization group. Here however, reasons are given to demand that, when gravity is coupled to the system, local conformal invariance should be a spontaneously broken exact symmetry. The argument has to do with the requirement that black holes obey a complementarity principle relating ingoing observers to outside observers, or equivalently, initial states to final states. This condition fixes all parameters, including masses and the cosmological constant. We suspect that only examples can be found where these are all of order one in Planck units, but the values depend on the algebra chosen. This paper combines findings reported in two previous preprints, and puts these in a clearer perspective by shifting the emphasis towards the implications for particle models.

description: We report the use of the DBU-CO2 switchable solvent system for the direct electrospinning of cellulose. Two cellulose types were investigated, i.e. microcrystalline cellulose (MCC) and cellulose pulp (CP). The morphologies of the obtained cellulose fibers were studied using scanning electron microscopy and optical microscopy. Results obtained showed that only particles with mean diameter about 1.2 μm could be obtained when MCC was used, even at high concentration (10 wt%). In the case of CP, an optimized concentration of 4 wt% resulted in standing fibers with a mean diameter of about 500nm. In order to improve the spinnability of the cellulose, different concentrations and ratios of PVA in combination with cellulose were investigated. The combination of cellulose (both MCC and CP) resulted in the formation of a unique fiber morphology, characterized by a homogeneous bead-like structure. An in-depth study of the fiber structure was carried out using Raman spectroscopy and showed that both cellulose and PVA were present in the formed beads. Finally, the challenge observed remained a complete removal of the solvents, which are not volatile enough, as well as explore a coagulation collection process for the fiber recovery in order to recover and re-use the employed solvent.
