The diversity of northwest coast shell middens : late pre-contact settlement-subsistence patterns on Valdes Island, British Columbia
Creators: name: McLay, Eric Boyd
Publisher: name: University of British Columbia
Year: 2009

description: This study explores the nature of late pre-contact settlement-subsistence activity (1400/1000 - 200 B.P.) on Valdes Island, a large southern Gulf Island in the Gulf of Georgia region of the Northwest Coast. Settlement-subsistence patterns on Valdes Island demonstrate an economic orientation toward exploiting critical resource locations in the marine environment, specifically sandy intertidal environments and tidal streams, where populations aggregated to collect predictable, localized and abundant coastal resources, particularly shellfish and Pacific herring. The diversity of shell middens (or shell matrix sites (cf. Claasen 1998)) on Valdes Island agree with patterns of logistical mobility indicative of a "collector strategy" (cf. Binford 1980). The majority of small-sized, shallow shell matrix sites on Valdes Island represent limited-activity sites, such as shellfish resource-processing locations and task-specific field camps, where specific, highly localized resources in the coastal environment were collected. Large, deep, highly-stratified shell matrix sites on Valdes Island - several of which are identified as ethnographic Central Coast Salish Halkomelem winter villages - represent long-term residential bases located to maximize access multiple, overlapping coastal resource zones in proximity to the tidal streams and sandy foreshore environments of the southwest coast. This settlement study identifies an important strategy Central Coast Salish populations used to engage the highly variable, locally diverse nature of subsistence resources in the Gulf of Georgia was to strategically position settlement locations at dense, biologically-diverse marine micro-environments. This settlement strategy enabled these complex hunter-gatherer populations to generate economic surplus for subsistence, exchange and feasting, and provided the economic base for competition among elites.

description: We compute from quenched lattice QCD the ground state masses of the charmed hybrid mesons cbar c g, with exotic quantum numbers JPC=1-+, 0+- and 0--. The 0-- hybrid meson spectrum has never been provided by lattice simulations due to the difficulties to extract high gluonic excitations from noise. We employ improved gauge and fermion actions on the anisotropic lattice, which reduce greatly the lattice artifacts, and lead to very good signals. The data are extrapolated to the continuum limit, with finite size effects under well control. For 1-+ and 0+- hybrid mesons, the ground state masses are 4.405(38) GeV and 4.714(52) GeV. We predict for the first time from lattice QCD, the ground state mass of 0-- to be 5.883(146) GeV.

description: The most promising variation of the standard siren technique combines gravitational-wave (GW) data for binary neutron star (BNS) mergers with redshift measurements enabled by their electromagnetic (EM) counterparts, to constrain cosmological parameters such as $H_0$, $Ω_m$, and $w_0$. Here we evaluate the near- and long-term prospects of multi-messenger cosmology in the era of future GW observatories: Advanced LIGO Plus (A+, 2025), Voyager-like detectors (2030s), and Cosmic Explorer-like detectors (CE, 2035 and beyond). We show that the BNS horizon distance of $\approx 700$ Mpc for A+ is well-matched to the sensitivity of the Vera C. Rubin Observatory (VRO) for kilonova detections. We find that one year of joint A+ and VRO observations will constrain the value of $H_0$ to percent-level precision, given a small investment of VRO time dedicated to target-of-opportunity GW follow-up. In the Voyager era, the BNS-kilonova observations begin to constrain $Ω_m$ with an investment of a few percent of VRO time. With the larger BNS horizon distance in the Cosmic Explorer era, on-axis short gamma-ray bursts (SGRBs) and their afterglows (though accompanying only some of the GW-detected mergers) supplant kilonovae as the most promising counterparts for redshift identification. We show that five years of joint observations with Cosmic Explorer-like facilities and a next-generation gamma-ray satellite with localization capabilities similar to that presently possible with Swift could constrain both $Ω_m$ and $w_0$ to $15-20\%$. We therefore advocate for a robust target-of-opportunity (ToO) program with VRO, and a wide-field gamma-ray satellite with improved sensitivity in the 2030s, to enable standard siren cosmology with next-generation gravitational wave facilities.

description: We study the spin-up of the accreting neutron stars with a realistic hyperon-softened equation of state. Using precise 2-D calculations we study the evolutionary tracks of accreting neutron stars in the angular-momentum - frequency plane. In contrast to the case of spinning-down solitary radio-pulsars, where a strong back-bending behavior has been observed, we do not see back-bending phenomenon in the accretion-powered spinning-up case. We conclude that in the case of accretion-driven spin-up the back-bending is strongly suppressed by the mass-increase effect accompanying the angular-momentum increase.

description: HD 179821 is an evolved star of unknown progenitor mass range (either post-Asymptotic Giant Branch or post-Red Supergiant) exhibiting a double peaked spectral energy distribution (SED) with a sharp rise from $\sim8-20$ $μ$m. Such features have been associated with ejected dust shells or inwardly truncated circumstellar discs. In order to compare SEDs from both systems, we employ a spherically symmetric radiative transfer code and compare it to a radiative, inwardly truncated disc code. As a case study, we model the broad-band SED of HD 179821 using both codes. Shortward of 40 $μ$m, we find that both models produce equivalent fits to the data. However, longward of 40 $μ$m, the radial density distribution and corresponding broad range of disc temperatures produce excess emission above our spherically symmetric solutions and the observations. For HD 179821, our best fit consists of a $T_{eff}=7000$ K central source characterized by $τ_V\sim1.95$ and surrounded by a radiatively driven, spherically symmetric dust shell. The extinction of the central source reddens the broad-band colours so that they resemble a $T_{eff}=5750$ K photosphere. We believe that HD 179821 contains a hotter central star than previously thought. Our results provide an initial step towards a technique to distinguish geometric differences from spectral modeling.

Testing asset pricing models using market expectations

description: We investigate the use of market-based expectations to test the CAPM and the conditional CAPM using a generalised method of moments framework. This method is valid under much weaker distributional assumptions and provides the procedure with robustness that commonly employed tests lack. Expected returns are derived from projected price levels of individual securities that are supplied in the form of twelve{u00AD}month consensus (median) target price forecasts. The annual forecasts, updated each month, are combined with dividend expectations to calculate the necessary time series of continuous expected returns. As such, we are able to avoid the use of instrumental variable models that, we argue, are likely to suffer from overfitting data concerns. In fact, we find that expected returns estimated from analyst data, while certainly not perfect, provide a better fit in comparison to the existing instrumental variable models. In considering the testable implication of the model via a vector of orthogonality conditions, we find that using market-based expectations to test the CAPM directly leads to a rejection. Overall, the CAPM tends to underestimate returns, producing pricing errors that are large, positive and statistically significant. Our results link in with the existing asset pricing literature that also attempts to apply forward-looking data derived from analyst forecasts. The conditional CAPM, a model that benefits from time-varying parameters that are updateable in accordance with changes to the information set, is also rejected. Market based expectations are used to parameterise the marginal rate of substitution. While the results of our tests of the conditional CAPM indicate that the model is able to perform better than those reported in previous studies, it continues to consistently underestimate returns in contravention to the null hypothesis. This indicates that the market, as the sole risk factor of the model, is not enough to explain the variation of returns across assets. While beta-risk may be priced, the CAPM may not account for all priced risk factors.

description: We report the discovery of 5 massive Wolf-Rayet (WR) stars resulting from a programme of follow-up spectroscopy of candidate emission line stars in the AAO/UKST Southern Galactic Plane H-alpha survey. The 6195-6775 angstrom spectra of the stars are presented and discussed. A WC9 class is assigned to all 5 stars through comparison of their spectra with those of known late-type WC stars, bringing the known total number of Galactic WC9 stars to 44. Whilst three of the five WC9 stars exhibit near infrared (NIR) excesses characteristic of hot dust emission -- as seen in the great majority of known WC9 stars -- we find that two of the stars show no discernible evidence of such excesses. This increases the number of known WC9 stars without NIR excesses to 7. Reddenings and distances for all 5 stars are estimated.

description: We investigate the impact of realistic 3D hydrodynamical model stellar atmospheres on the determination of elemental abundances in the carbon-rich, hyper iron-poor stars HE0107-5240 and HE1327-2326. We derive the chemical compositions of the two stars by means of a detailed 3D analysis of spectral lines under the assumption of local thermodynamic equilibrium (LTE). The lower temperatures of the line-forming regions of the hydrodynamical models cause changes in the predicted spectral line strengths. In particular we find the 3D abundances of C, N, and O to be lower by ~ -0.8 dex (or more) than estimated from a 1D analysis. The 3D abundances of iron-peak elements are also decreased but by smaller factors (~ -0.2 dex). We caution however that the neglected non-LTE effects might actually be substantial for these metals. We finally discuss possible implications for studies of early Galactic chemical evolution.

description: A generally covariant $U(1)^3$ gauge theory describing the $G_N \to 0$ limit of Euclidean general relativity is an interesting test laboratory for general relativity, specially because the algebra of the Hamiltonian and diffeomorphism constraints of this limit is isomorphic to the algebra of the corresponding constraints in general relativity. In the present work, we study boundary conditions and asymptotic symmetries of the $U(1)^3$ model and show that while asymptotic spacetime translations admit well-defined generators, boosts and rotations do not. Comparing with Euclidean general relativity, one finds that exactly the non-Abelian part of the $SU(2)$ Gauss constraint which is absent in the $U(1)^3$ model plays a crucial role in obtaining boost and rotation generators.

Ballcourts, competitive games, and the emergence of complex society
Creators: name: Hill, Warren D.
Publisher: name: University of British Columbia
Year: 2009

description: The processes that accompany the transition to social and political inequality have perplexed archeologists in their attempts to explain the emergence of complex society. Over the past decade, archaeological excavations in the Mazatan region of Chiapas, Mexico, has yielded new information on the processes surrounding this social and political transformation. Most recently, the earliest known ballcourt was discovered at the site of Paso de la Amada in the Mazatan region. This ballcourt predates all other known ballcourts by more than 500 years. For over 2500 years, ballcourts and the associated ballgame formed an integral part of religious, social, and political life of Mesoamerican complex societies. The tremendous success of the ballgame lies in its ability to act as a medium of social and political integration while simultaneously encouraging intense rivalry. This dissertation uses ballcourts and competitive games to address the larger question of how social and political inequality evolves. Using architectural, artifactual, and settlement pattern data, I argue that an emerging complex society was involved in the construction and use of the ballcourt at Paso de la Amada. I suggest that elites sponsored the ballcourt construction, enabling them to expand their regional networks and enhance their own social positions. I present evidence to support these claims, and review several existing models for the emergence of complex society in light of this discovery. I conclude that competitive games and gaming facilities, such as ballcourts, played a crucial role in the emergence of complex society in Mesoamerica and have significant implications for how this process is modeled.

description: In the past, it was a common practice to test cosmetics and skin relevant chemicals directly on humans or animals, as testing protocols lacked standardised and ethical guidelines were not established. As a result, the emergence of alternative in vitro models produced today allow for safer, controlled, and a more ethical responsible pathway for drug and cosmetic testing. This thesis focuses on the fabrication of a trilayered in vitro skin model within a laboratory environment as a platform for testing cosmetics.

Commercial in vitro skin models are available but are limited to simpler monolayers models or basic bilayered constructs that fail to replicate the complex architecture and function of human skin. In attempt to better recreate the functionality of human skin within a laboratory environment, various photocrosslinkable hydrogels were investigated for their ability to support appropriate cell-material interactions. However, bulk hydrogel scaffolds, commonly used by research groups to fabricate in vitro skin models, present limitations, such as the lack of nutrient diffusion through a bulk crosslinked hydrogel. Therefore, this thesis explores alternative biofabrication methods of scaffolds that support appropriate cell-material interactions. This thesis investigated the development of single layer skin models into a more representative trilayered skin construct.

Key aspects of hydrogel selection and material properties were evaluated to improve keratinocyte and fibroblast proliferation, relevant differentiation, and matrix deposition. It was found that collagen I, 3 and 4 gene expression levels were higher for bilayered models, as opposed to single layered models. This highlighted the importance of including appropriate cell types and architecture to better represent human skin. By using different biofabrication techniques, microgels made from 6% HM gelMA were crosslinked into a 3D scaffold and supported some formation of collagen 4 networks, which are characteristic of subcutaneous adipose tissue. Diffusion (demonstrated by diffusion coefficient analysis) was improved within the microgel scaffold compared to the bulk hydrogel control.

Overall, this research supports the development of more complex in vitro skin models, which can be used for testing cosmetic products. This was demonstrated by the application of eyeliner to the fabricated trilayered model.

description: Stereo matching is one of the fundamental tasks in early vision. Unlike human brain recognizes objects and estimates the depth easily, it is difficult to design algorithms that perform well on a computer due to variations of illumination, occlusion or textureless. Like most of the early vision problems, stereo matching can be formulated as an energy minimization problem in which the optimal depth is the one with the lowest energy. And graph cuts is one of the efficient and effective minimization tools that avoids the problems of local minima. Conventional energy functions are defined on Markov Random Fields (MRFs) with a 4-connected grid structure derived from the image, however it is incapable of expressing complex relationship between group of pixels. This thesis focuses on exploring some aspects of stereo matching problems through higher-order structure and higher-order graph cuts. The first problem I address relates to the evaluation of five state-of-the-art segmentation approaches. Their different contributions to segment-based stereo matching have been quantitatively measured and analyzed. This works aim at helping researchers to choose the segmentation approach that most suitable for their stereo matching application. The second part of the thesis proposes a novel approach to dense stereo matching. This method features sub-segmentation and adopts a higher-order potential to enforce the label consistency inside segments as a soft constraint. Moreover, several successful techniques have been combined. Experiments show that this approach obtains state-of-the-art results while still keeping efficiency. In the last part of the thesis, a novel two-layer MRFs framework is presented in which stereo matching and surface boundary estimation are combined. Both properties are inferred simultaneously and globally so that they can benefit each other. This work has direct application in phosphene vision based human indoor navigation. Experiments prove that the proposed framework achieves significantly better performance than other popular methods in all resolutions.

description: Despite the importance of Type Ia supernovae (SNe Ia) throughout astronomy, the precise progenitor systems and explosion mechanisms that drive SNe Ia are still unknown. An explosion scenario that has gained traction recently is the double detonation in which an accreted shell of He detonates and triggers a secondary detonation in the underlying white dwarf. Our research presents a number of high resolution, multi-dimensional, full star simulations of thin-He-shell, sub-Chandrasekhar-mass white dwarf progenitors that undergo a double detonation. This suite of thin-shell progenitors incorporates He shells that are thinner than those in previous multi-dimensional studies. We confirm the viability of the double detonation across a range of He shell parameter space as well as present bulk yields and ejecta profiles for each progenitor. The yields obtained are generally consistent with previous works and indicate the likelihood of producing observables that resemble SNe Ia. The dimensionality of our simulations allow us to examine features of the double detonation more closely, including the details of the off-center secondary ignition and asymmetric ejecta. We find considerable differences in the high-velocity extent of post-detonation products across different lines of sight. The data from this work will be used to generate predicted observables and may further support the viability of the double detonation scenario as a SNe Ia channel as well as show how properties of the progenitor or viewing angle may influence trends in observable characteristics.

description: Results of a lattice field theory simulation of the single-flavor Thirring model in 2+1 spacetime dimensions are presented. The lattice model is formulated using domain wall fermions as a means to recover the correct U(2) symmetries of the continuum model in the limit where wall separation $L_s\to\infty$. Simulations on $12^3, 16^3\times L_s$, varying self-interaction strength $g^2$ and bare mass $m$ are performed with $L_s = 8, \ldots 48$, and the results for the bilinear condensate $\langle\barψψ\rangle$ fitted to a model equation of state assuming a U(2)$\to$U(1)$\otimes$U(1) symmetry-breaking phase transition at a critical $g_c^2$. First estimates for $g^{-2}a$ and critical exponents are presented, showing small but significant departures from mean-field values. The results confirm that a symmetry-breaking transition does exist and therefore the critical number of flavors for the Thirring model $N_c > 1$. Results for both condensate and associated susceptibility are also obtained in the broken phase on $16^3\times48$, suggesting that here the $L_s\to\infty$ extrapolation is not yet under control. We also present results obtained with the associated 2+1$d$ truncated overlap operator DOL demonstrating exponential localisation, a necessary condition for the recovery of U(2) global symmetry, but that recovery of the Ginsparg-Wilson condition as $L_s\to\infty$ is extremely slow in the broken phase.

description: Ultrafast transmission changes around the fundamental trion resonance are studied after exciting a p-shell exciton in a negatively charged II-VI quantum dot. The biexcitonic induced absorption reveals quantum beats between hot trion states at 133 GHz. While interband dephasing is dominated by relaxation of the P-shell hole within 390 fs, trionic coherence remains stored in the spin system for 85 ps due to Pauli blocking of the triplet electron. The complex spectro-temporal evolution of transmission is explained analytically by solving the Maxwell-Liouville equations. Pump and probe polarizations provide full control over amplitude and phase of the quantum beats.

description: By considering a new form of dimensional reduction for noncommutative field theory, we show that the signature of spacetime may be changed. In particular, it is demonstrated that a temporal dimension can emerge from a purely Euclidean geometry. We suggest that this mechanism may hint at the origin of time in the fundamental theory of quantum gravity.

description: The CCAT-prime project's first light array will be deployed in Mod-Cam, a single-module testbed and first light cryostat, on the Fred Young Submillimeter Telescope (FYST) in Chile's high Atacama desert in late 2022. FYST is a six-meter aperture telescope being built on Cerro Chajnantor at an elevation of 5600 meters to observe at millimeter and submillimeter wavelengths.1 Mod-Cam will pave the way for Prime-Cam, the primary first generation instrument, which will house up to seven instrument modules to simultaneously observe the sky and study a diverse set of science goals from monitoring protostars to probing distant galaxy clusters and characterizing the cosmic microwave background (CMB). At least one feedhorn-coupled array of microwave kinetic inductance detectors (MKIDs) centered on 280 GHz will be included in Mod-Cam at first light, with additional instrument modules to be deployed along with Prime-Cam in stages. The first 280 GHz detector array was fabricated by the Quantum Sensors Group at NIST in Boulder, CO and includes 3,456 polarization-sensitive MKIDs. Current mechanical designs allow for up to three hexagonal arrays to be placed in each single instrument module. We present details on this first light detector array, including mechanical designs and cold readout plans, as well as introducing Mod-Cam as both a testbed and predecessor to Prime-Cam.

Kinetic and spectroscopic studies of the redox centers of photosystem II

description: The work conducted in this thesis aimed to elucidate the function of key components of the photosystem II (PS II) enzyme. Several experimental methodologies were employed, allowing a complete snap-shot of the enzyme in a particular meta-stable state. Particular emphasis was placed on resolving processes that occur within the PS II enzyme at redox cofactors involved in electron transfer. Topics addressed in this thesis include the following: Protein mediated electron transfer between the light active pigments (P680) and the metal catalytic site - the oxidation of the redox active tyrosine D116 (Yz) of the D1 polypeptide. It was shown that the Yz{u2022} weakly interacts (dipolar only) with the S{u2081} state Mn cluster of the OEC. A model for water molecule mediated H-bond bridging between the Mn cluster and Yz{u2022} is discussed. This model rationalizes both observed substrate water exchange rates and the patterns of 'split signal' ESR line-shapes seen in the various S states. The low temperature carotenoid donor of PS II - associated with photo-protection - is heterogeneous. A significant fraction exhibits weak magnetic interaction with its surrounding environment -possibly with the ferr-cytochrome b559, ~12 {u00C5} away. From the latest PS II structural data, this implies the major carotenoid donor is that closest to P680, CarD. Comparison with earlier results on ca{u207A} radicals in PS II and in vitro suggest that CarD{u207A} may have two conformational states, corresponding to a localized or de-localised charge distribution along the chain. The electronic structure of the primary plasto-quinone acceptor (QA) of PS II. The ESR spectrum of the native semi-quinone iron signal was simulated using the spin Hamiltonian formalism. By comparison with density functional theory calculations, the native exogenous ligand to the non-heme iron of PS II is suggested to be carbonate. Its role in proton mediation to QB is discussed. The nature of the primary electron acceptor( pheoD1) of PS II. The Q{u03B3} excitation of the pheosD1, was shown to be dominantly at 683 nm (in spinach). Its coupling to the neighboring accessory chlorophyll (chID1) is estimated to be small (< 10 cm{u207B}{u00B9}). The kinetics of photo-assembly of the inorganic core -the site of water oxidation. A Markov analysis was used to interpret the mechanism of photo-activation. By varying the turnover (photo-induced advancement) conditions used to photo-assemble the apo-WOC-PS II inorganic core, the complete kinetics of photo-assembly were deduced.

description: A virtual "digital twin" experiment using web browser based iLabs client of the 3 Point Bend test delivered at the department of Multidisciplinary Engineering Education at the University of Sheffield.Stanford University has developed a platform referred to as “iLab”, which allows students to access data from real experiments in an interactive way. It is described as a “digital twin”. However, the system is not a true simulation, as the outcomes of physical processes are not produced in a dynamic way based on the inputs.  During a laboratory experiment, a number of independent variables are set and for each combination of these, an output state of the system is produced.  The iLabs system allows instructors to upload photographic images and numerical data for a large number of output states for any particular experiment. Following the upload to the system, students are able to retrieve individual output states by specifying a combination of inputs from an open access web based interface. In practice, this gives students control of the beam shape, beam material and applied load (and measurement of beam deflection), in the same way as the real experiment.A semi-automated system using remotely controlled Raspberry Pi (RPi) based cameras was used to capture the photographs of the experiment in its many input/output states. Once the framing of each camera is established to capture critical viewpoints of the experimental equipment, a command line based UI is used to capture numerical data from instrumentation and remotely instruct the simultaneous capture of images from the cameras. The cameras do not need to be touched, so the framing is not changed and data, including the filenames of the digital images, is exported in the format required to directly upload to iLabs.

Merger rate of black hole binaries from globular clusters: theoretical error bars and comparison to gravitational wave data from GWTC-2

description: Black hole binaries formed dynamically in globular clusters are believed to be one of the main sources of gravitational waves in the Universe. Here, we use our new population synthesis code, cBHBd, to determine the redshift evolution of the merger rate density and masses of black hole binaries formed in globular clusters. We simulate $\sim 2$ million models to explore the parameter space that is relevant to real clusters and over all mass scales. We show that when uncertainties on the initial cluster mass function and density are properly taken into account, they become the two dominant factors in setting the theoretical error bars on merger rates. Other model parameters (e.g., natal kicks, black hole masses, metallicity) have virtually no effect on the local merger rate density, although they affect the masses of the merging black holes. Modelling the merger rate density as a function of redshift as $R(z)=R_0(1+z)^κ$ at $z<2$, and marginalizing over uncertainties, we find: $R_0=7.2^{+21.5}_{-5.5}{\rm Gpc^{-3}yr^{-1}}$ and $κ=1.6^{+0.4}_{-0.6}$ ($90\%$ credibility). The rate parameters for binaries that merge inside the clusters are ${R}_{\rm 0,in}=1.6^{+1.9}_{-1.0}{\rm Gpc^{-3}yr^{-1}}$ and $κ_{\rm in}=2.3^{+1.3}_{-1.0}$; $\sim 20\%$ of these form as the result of a gravitational-wave capture, implying that eccentric mergers from globular clusters contribute $\lesssim 0.4 \rm Gpc^{-3}yr^{-1}$ to the local rate. A comparison to the merger rate reported by LIGO-Virgo shows that a scenario in which most of the detected black hole mergers are formed in globular clusters is consistent with current constraints, and requires initial cluster half-mass densities $\gtrsim 10^4 M_\odot \rm pc^{-3}$. Such models also reproduce the inferred primary black hole mass distribution for masses $13-30 M_\odot$, but under-predict the data outside this range.

description: We calculate the integrated-pulse quantum efficiency of single-photon sources in the cavity quantum electrodynamics (QED) strong-coupling regime. An analytical expression for the quantum efficiency is obtained in the Weisskopf-Wigner approximation. Optimal conditions for a high quantum efficiency and a temporally localized photon emission rate are examined. We show the condition under which the earlier result of Law and Kimble [J. Mod. Opt. 44, 2067 (1997)] can be used as the first approximation to our result.
