Radii of Rapidly-Rotating Stars, with Application to Transiting-Planet Hosts
Creators: name: Brown, Timothy M.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: The currently favored method for estimating radii and other parameters of transiting-planet host stars is to match theoretical models to observations of the stellar mean density rho_*, the effective temperature T_eff, and the composition parameter [Z]. This explicitly model-dependent approach is based on readily-available observations, and results in small formal errors. Here I use two calibration samples of stars (eclipsing binaries and stars for which asteroseismic analyses are available) having well-determined masses and radii to estimate the accuracy and systematic errors inherent in the rho_* method. When matching to the Yonsei-Yale stellar evolution models, I find the most important systematic error results from selection bias favoring rapidly-rotating (hence probably magnetically active) stars among the eclipsing binary sample. If unaccounted for, this bias leads to a mass-dependent underestimate of stellar radii by as much as 4% for stars of 0.4 M_sun, decreasing to zero for masses above about 1.4 M_sun. The asteroseismic sample suggests (albeit with significant uncertainty) that systematic errors are small for slowly-rotating, inactive stars. Systematic errors arising from failings of the Yonsei-Yale models of inactive stars probably exist, but are difficult to assess because of the small number of well-characterized comparison stars having low mass and slow rotation. Poor information about [Z] is an important source of random error, and may be a minor source of systematic error as well. With suitable corrections for rotation, it is likely that systematic errors in the rho_* method can be comparable to or smaller than the random errors, yielding radii that are accurate to about 2% for most stars.

description: Individuals of different types, may it be genetic, cultural, or else, with different levels of fitness often compete for reproduction and survival. A fitter type generally has higher chances of disseminating their copies to other individuals. The fixation probability of a single mutant type introduced in a population of wild-type individuals quantifies how likely the mutant type spreads. How much the excess fitness of the mutant type increases its fixation probability, namely, the selection pressure, is important in assessing the impact of the introduced mutant. Previous studies mostly based on undirected and unweighted contact networks of individuals showed that the selection pressure depends on the structure of networks and the rule of reproduction. Real networks underlying ecological and social interactions are usually directed or weighted. Here we examine how the selection pressure is modulated by directionality of interactions under several update rules. Our conclusions are twofold. First, directionality discounts the selection pressure for different networks and update rules. Second, given a network, the update rules in which death events precede reproduction events significantly decrease the selection pressure than the other rules.

description: We extend the formalism of entanglement renormalization to the study of boundary critical phenomena. The multi-scale entanglement renormalization ansatz (MERA), in its scale invariant version, offers a very compact approximation to quantum critical ground states. Here we show that, by adding a boundary to the scale invariant MERA, an accurate approximation to the critical ground state of an infinite chain with a boundary is obtained, from which one can extract boundary scaling operators and their scaling dimensions. Our construction, valid for arbitrary critical systems, produces an effective chain with explicit separation of energy scales that relates to Wilson's RG formulation of the Kondo problem. We test the approach by studying the quantum critical Ising model with free and fixed boundary conditions.

description: Deoxymiroestrol is the most potent phytoestrogen in the chromene group found in Pueraria candollei. The estrogenic activity of P. candollei, functions as hormone replacement therapy in postmenopausal women. This study established an enzyme-linked immunosorbent assay (ELISA) for quantifying deoxymiroestrol using fragment antigen-binding (Fab) antibody to improve analytical performance. Our ELISA specifically detected deoxymiroestrol in the range of 31.25–1,000 ng/mL. Intra- and inter-assay precision was 1.48%–7.11% and 0.58%–9.31%, respectively, the recovery of authentic deoxymiroestrol spiked into samples was 99.77%–101.61%, and the limit of detection was 30.80 ng/mL. The findings of P. candollei root bark determined using our developed ELISA with Fab antibody and an ELISA with anti-deoxymiroestrol polyclonal antibody were consistent (R2 = 0.9807). The developed ELISA can be applied to the quality control of deoxymiroestrol derived from P. candollei.

description: Fast Congestion Notification (FN) is one of the proactive queue management mechanisms that practices congestion avoidance to help avoid the beginning of congestion by marking or dropping packets before the routers queue gets full; and exercises congestion control, when congestion avoidance fails, by increasing the rate of packet marking or dropping. Technically, FN avoids the queue overflows by controlling the instantaneous queue size below the optimal queue size, and control congestion by keeping the average arrival rate close to the outgoing link capacity. Upon arrival of each packet, FN uses the instantaneous queue size and the average arrival rate to calculate the packet marking or dropping probability. FN marks or drops packets at fairly regular intervals to avoid long intermarking intervals and clustered packet marks or drops. Too many marked or dropped packets close together can cause global synchronization, and also too long packet intermarking times between marked or dropped packets can cause large queue sizes and congestion. This paper shows how FN controls the queue size, avoids congestion, and reduces global synchronization by uniformizing marked or dropped packet intervals.

description: Nanomechanical oscillators are at the heart of ultrasensitive detectors of force, mass and motion. As these detectors progress to even better sensitivity, they will encounter measurement limits imposed by the laws of quantum mechanics. For example, if the imprecision of a measurement of an oscillator's position is pushed below the standard quantum limit (SQL), quantum mechanics demands that the motion of the oscillator be perturbed by an amount larger than the SQL. Minimizing this quantum backaction noise and nonfundamental, or technical, noise requires an information efficient measurement. Here we integrate a microwave cavity optomechanical system and a nearly noiseless amplifier into an interferometer to achieve an imprecision below the SQL. As the microwave interferometer is naturally operated at cryogenic temperatures, the thermal motion of the oscillator is minimized, yielding an excellent force detector with a sensitivity of 0.51 aN/rt(Hz). In addition, the demonstrated efficient measurement is a critical step towards entangling mechanical oscillators with other quantum systems.

description: We consider current precision electroweak data, Z' searches and dark matter constraints and analyse their implications for an extension of the SM that includes an extra U(1)' massive gauge boson and a particular hidden sector ("hidden valley") with a confining (QCD-like) gauge group. The constraints on the Z' with arbitrary Z-Z' kinetic mixing coming from direct searches and precision tests of the Standard Model are analysed and shown to lead to a lower limit of 800 GeV on its mass. Renormalisable interactions involving the Z' probe the physics of the hidden valley sector which contains a pseudoscalar dark matter candidate. We find that dark matter constraints place an upper bound on the mass of the Z' of O(10) TeV. A TeV mass scale is needed for the hidden valley states, and the Sommerfeld factor for p-wave dark matter annihilation is found significantly to suppress the allowed parameter space of the model.

Exploring factors affecting attendance in a diabetes prevention program amongst first-generation Afghan immigrants residing in the Okanagan region of British Columbia
Creators: name: Bohlouli Masouleh, Azar
Publisher: name: University of British Columbia
Year: 2024

description: Background: As global immigration escalates, host nations must adapt to the diverse needs of new arrivals (Chand & Tung, 2019; Hilado et al., 2021; WHO, 2023). Immigrants forced to leave their homes often lack opportunities to learn about healthy behaviours, resources to practice health behaviours, or access proper treatment, compared to those who have not experienced forced resettlement (Hilado et al., 2021; WHO, 2023). The resettlement processes can also deteriorate health, making immigrants particularly vulnerable to non-communicable diseases like Type 2 Diabetes (T2D) (Qureshi et al., 2023; Towne et al., 2021; Wagner et al., 2020). Factors such as low socio-economic status, resettlement stress, acculturation challenges and traumatic life events may contribute to lower participation rates in diabetes prevention programs within host communities (Brown et al., 2023; Joachim-Célestin et al., 2020; Khatri & Assefa, 2022; Nieto-Martínez et al., 2023; van der Boor et al., 2020). This study aimed to understand the barriers and facilitators to attending a diabetes prevention program (DPP) amongst first-generation Afghan immigrants in the Okanagan region of British Columbia (BC) with a social constructivism lens, using the Theoretical Domain Framework (TDF) to identify key domains influencing program attendance. Methodology: 10 participants engaged in semi-structured interviews to explore perceived barriers and facilitators to diabetes prevention program attendance. Data were analysed abductively, with TDF as the deductive framework and Braun and Clarke’s six phases for thematic analysis for inductive analysis (Braun & Clarke, 2006). Results: The analyses identified 146 facilitators and 39 barriers in total. The most frequently reported barriers affecting participant’s decision to attend a diabetes prevention program were coded as TDF domains: Knowledge, Environmental context and resources, and Social influence. Inductive coding resulted in three themes: 1. Deprivation of Life/Growth Opportunities, 2. Sociocultural and Environmental factors, and 3. Reciprocal community support. Conclusion: Findings of this study highlight the need for culturally tailored features in community-based diabetes prevention programs to enhance their acceptability and effectiveness in immigrant populations living in Okanagan, Canada. This study also highlights the importance of such programs in aiding immigrant integration into communities. Applying these findings can enhance program adaptation for newcomers and minorities in Canada.

description: A palynological study of 239 outcrop samples and their sedimentological context was undertaken on the Pliocene Productive Series in the Kirmaky and Yasamal valleys, eastern Azerbaijan. The Productive Series is primarily a representation of the palaeo-Volga and forms the main hydrocarbon-producing reservoirs in the South Caspian Basin. Most sands are interpreted as fluvial, based on sedimentary characteristics. Mudstone and siltstones often contain freshwater and brackish assemblages interpreted as ‘Caspian lake’ transgressions, indicative of rapid Caspian Sea level change during the Pliocene. Most samples contain rich assemblages including pollen, spores, dinoflagellate cysts, algae and fungal bodies. Common tree pollen elements include Pinus, Alnus, Betula, Carya, Juglans, Pterocarya, Quercus and Ulmus, which all occur in present-day vegetation or pollen records from the Caucasus or Urals. Herbaceous pollen includes Amaranthaceae, Asteraceae (including Artemisia), Ephedra and Poaceae, commonly found in the drier Caspian regions. The dinoflagellate cysts include ‘Peri-paratethyan endemic’ taxa such as Caspidinium rugosum and Spiniferites cruciformis. ‘Pannonian’ species such as Thalassiphora balcanica, Romanodinium areolatum and Spiniferites oblongus confirm the persistence of these taxa into the early Pliocene in Eastern Paratethys, around five million years later than their first documented presence in Central Paratethys. ‘Caspian lake’ influences diminish up-section, as indicated by a progression from brackish to freshwater and sub-aerial conditions. Productive Series deposition was mainly driven by the combined effects of lake level and catchment climate. The principal hydrocarbon reservoir sands were deposited as a result of increased catchment humidity, whereas drying conditions led to reduced coarse clastic input and deposition of alluvial plain mudstones. Productive Series deposition terminated with the onset of the marine-influenced Akchagyl Series, which spans the Plio-Pleistocene boundary. The lowermost sediments of the Akchagyl Series are freshwater in origin and grade up-section into marine beds containing dinoflagellate cysts of Arctic affinity.

description: A numerous population of weak line galaxies (WLGs) is often left out of statistical studies on emission line galaxies (ELGs) due to the absence of an adequate classification scheme, since classical diagnostic diagrams, like [OIII]/Hb vs [NII]/Ha (the BPT diagram), require the measurement of at least 4 emission lines. This paper aims to remedy this situation by transposing the usual divisory lines between Star Forming (SF) and AGN hosts, and between Seyferts and LINERs to diagrams that are more economical in terms of line quality requirements. By doing this, we rescue from the classification limbo a substantial number of sources and modify the global census of ELGs. More specifically: (1) We use the SDSS DR7 to constitute a suitable sample of 280k ELGs, 1/3 of which are WLGs. (2) Galaxies with strong emission lines are classified using the widely applied criteria of Kewley et al (2001), Kauffmann et al (2003), Stasinska et al (2006) and Kewley et al (2006). (3) We transpose these classification schemes to alternative diagrams keeping [NII]/Ha as a horizontal axis, but replacing Hb by a stronger line (Ha or [OII]), or substituting [OIII]/Hb ratio with the equivalent width of Ha. Optimized equations for the transposed divisory lines are provided. (4) We show that nothing significant is lost in the translation, but that the new diagrams allow one to classify up to 50% more ELGs. (5) Introducing WLGs in the census of galaxies in the local Universe increases the proportion of metal-rich SF galaxies and especially LINERs. (abridged)

description: In physical science, the concept of \emph{emergence} is often used to describe phenomena that occur at macroscopic scales but not at microscopic scales. The latter is usually referred to as a \emph{fundamental property} and the former as an \emph{emergent property}. In this paper, noncommutative geometry, often viewed as an offshoot of string theory, is the primary fundamental theory that gives rise to macroscopic wormholes and their properties, thereby becoming an emergent phenomenon. As a consequence of these considerations, we will reexamine the boundary conditions that characterize a Morris-Thorne wormhole. The result is a significant modification of the wormhole structure.

description: All to all broadcast is a collective communication in a network with the constraint that every node must send to each other certain piece of its data. This paper addresses the problem of optimal all port all to all broadcast in multidimensional tori. The optimality criteria considered are the minimum exchange steps, no duplicated data in the sense that only new data are conveyed to receivers and the balance of the communication links load. It is proved that under these constraints, an optimal broadcast is not feasible in any multidimensional torus. Then, the tori which are capable of optimal broadcasts are characterized.

Extreme Sensitivity of the YORP Effect to Small-Scale Topography

Publisher: name: arXiv
Year: 2009
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: Radiation recoil (YORP) torques are shown to be extremely sensitive to small-scale surface topography. Starting from simulated objects representative of the near-Earth object population, random realizations of three types of small-scale topography are added: Gaussian surface fluctuations, craters, and boulders. For each, the resulting expected relative errors in the spin and obliquity components of the YORP torque are computed. Gaussian power produces errors of order 100% if observations constrain the surface to a spherical harmonic order l < 10. A single crater with diameter roughly half the object's mean radius, placed at random locations, results in errors of several tens of percent. Boulders create torque errors roughly 3 times larger than do craters of the same diameter. A single boulder comparable to Yoshinodai on 25143 Itokawa, moved by as little as twice its own diameter, can alter the magnitude of the torque by factors of several, and change the sign of its spin component at all obliquities. A YORP torque prediction derived from groundbased data can be expected to be in error by of order 100% due to unresolved topography. Small surface changes caused by slow spin-up or spin-down may have significant stochastic effects on the spin evolution of small bodies. For rotation periods between roughly 2 and 10 hours, these unpredictable changes may reverse the sign of the YORP torque. Objects in this spin regime may random-walk up and down in spin rate before the rubble-pile limit is exceeded and fissioning or loss of surface objects occurs. Similar behavior may be expected at rotation rates approaching the limiting values for tensile-strength dominated objects.

Advancing equity in water demand management among local governments in British Columbia, Canada
Creators: name: Chireh, Vincent Kuuteryiri
Publisher: name: University of British Columbia
Year: 2024

description: Sustainable management of and equitable access to water have become pressing and shared global concerns requiring innovative approaches. The stress on water resources and untenable supply-side management have compelled local governments and utilities to employ measures and practices to promote conservation and reduce usage—including bundles of policies often referred to as Water Demand Management (WDM). Among other things, these policies can reduce wasteful water use/losses, ensure fair distribution and billing, and promote efficient use. However, the ways that policymakers formulate and implement these policies have equity implications – often including increased costs, supply disconnections, and the exclusion of some groups from the implementation process. This dissertation employs a mixed-methods approach, combining quantitative surveys and semi-structured interviews, to examine the equity implications of WDM. In doing so, the dissertation synthesizes how equity is conceptualized and impacted by WDM policies in the scholarly literature. From water policymakers’ perspective, the thesis then examines the progress regarding how jurisdictions prioritize, plan, and implement various WDM policies in British Columbia. Analyzing semi-structured interviews with mayors, chief administrative officers, and public works officers in metered jurisdictions helps to understand how they conceptualize equity and seek to address inequities in their local contexts. The dissertation finds that equity is mainly perceived as equality, where the cost and benefits of WDM are shared among water users in line with the cost-of-service principle. While the province is increasingly adopting these measures to conserve water and reduce usage, the analysis also suggests that efforts are needed to address potential associated access and affordability challenges. This dissertation contributes to the ongoing discourse on sustainable water management and equity, shedding light on the potential negative impacts of WDM policies, and considerations going forward.

description: We present numerical simulations to model the production of observable long-period comets (LPCs) from the Oort Cloud, a vast reservoir of icy bodies surrounding the Sun. We show that inner Oort Cloud objects can penetrate Jupiter's orbit via a largely unexplored dynamical pathway, and they are an important, if not the dominant, source of known LPCs. We use this LPC production to place observationally motivated constraints on the population and mass of the inner Oort Cloud, which are consistent with giant planet formation theory. These constraints indicate that only one comet shower producing late Eocene bombardment levels has likely occurred since the Cambrian Explosion, making these phenomena an improbable cause of additional extinction events.

description: We introduce a simple generalization of the basic holographic superconductor model in which the spontaneous breaking of a global U(1) symmetry occurs via the Stueckelberg mechanism. This more general setting allows tuning features such as the order of the transition. The physical vacuum of the condensed phase and the order of the transition are determined by a detailed analysis of the free energy of the system. For first order transitions, we identify a metastable phase above the critical temperature. In this case, the conductivity shows additional poles, thus suggesting that the condensate has internal structure. We comment on the possibility of obtaining second order phase transitions with non mean-field critical exponents.

description: We have combined the large SN Ia database of the Canada-France-Hawaii Telescope Supernova Legacy Survey and catalogs of galaxies with photometric redshifts, VLA 1.4 GHz radio sources, and Spitzer infrared sources. We present eight SNe Ia in early-type host galaxies which have counterparts in the radio and infrared source catalogs. We find the SN Ia rate in subsets of radio and infrared early-type galaxies is ~1-5 times the rate in all early-type galaxies, and that any enhancement is always

Topological superconductivity in twisted cuprates and device applications inspired by their Josephson physics
Creators: name: Can, Oguzhan
Publisher: name: University of British Columbia
Year: 2024

description: In this thesis we explore the physics of moiré heterostructures of few-layer d-wave superconductor thin films. We show that such a twisted bilayer stack exhibits spontaneous time reversal symmetry breaking near 𝜃 = 45º twist, leading to a chiral superconductor state with topological edge modes. We then discuss the signatures of this prediction in polar Kerr effect experiments and find that expected Kerr rotation is three orders of magnitude larger compared to strontium ruthenate, one of the most studied chiral topological superconductor candidates. Another experimental signature of this novel phase we predict turns out to be the superconducting diode effect, which has recently been observed in twisted cuprate bilayers. Inspired by this experimental observation and the Josephson current-phase behaviour of this system, we introduce a novel superconducting circuit element made out of arrays of conventional Josephson junctions which can be printed on a Al or Nb superconducting chip relying on available fabrication technology for practical applications. Finally, we propose a novel superconducting qubit design and discuss its advantages over existing superconducting qubits.
Mixed Heavy Quark Hybrid Mesons, Decay Puzzles, and RHIC

description: We estimate the energy of the lowest Charmonium and Upsilon states with hybrid admixtures using the method of QCD Sum Rules. Our results show that the $Ψ'(2S)$ and $Υ(3S)$ states both have about a 50% admixture of hybrid and meson components. From this we find explanations of both the famous $ρ-π$ puzzle for Charmonium, and the unusual pattern of $σ$ decays that have been found in $Υ$ decays. Moreover, this picture can be used for predictions of heavy quark production with the octet model for RHIC.

description: Motivated by the recent interest aroused by non-dynamical axionic electrodynamics in the context of topological insulators and Weyl semimetals, we discuss a simple model of the magnetoelectric effect in terms of a $θ$-scalar field that interacts through a delta-like potential located at a planar interface. Thus, in the bulk regions the field is constructed by standard free waves with the absence of evanescent components. These waves have to be combined into linear superposition to account for the boundary conditions at the interface in order to yield the corresponding normal modes. Our aim is twofold: first we quantize the $θ$-scalar field using the normal modes in the canonical approach and then we look for applications emphasizing the effect of momentum non-conservation due to the presence of the interface. To this end we calculate the decay of a standard scalar particle into two $θ$-scalar particles showing the opening of new decay channels. As a second application we deal with the two body scattering of standard charged scalar particles mediated by a $θ$-scalar particle, focusing on the momentum non-conserving contribution of the scattering amplitude ${\cal M}^{NC}$. We define a generalization of the usual cross section in order to quantify the emergence of these events. We also study the allowed kinematical region for momentum non-conservation as well as the position of the poles of the amplitude ${\cal M}^{NC}$. Finally, the ratio of the magnitudes between ${\cal M}^{NC}$ and the momentum conserving amplitude is discussed in the appropriate region of momentum space.
Exact time-reversal focusing of acoustic and quantum excitations in open cavities: The perfect inverse filter

description: The time-reversal mirror (TRM) prescribes the reverse playback of a signal to focalize an acoustic excitation as a Loschmidt echo. In the quantum domain, the perfect inverse filter (PIF) processes this signal to ensure an exact reversion provided that the excitation originated outside the cavity delimited by the transducers. We show that PIF takes a simple form when the initial excitation is created inside this cavity. This also applies to the acoustical case, where it corrects the TRM and improves the design of an acoustic bazooka. We solve an open chaotic cavity modeling a quantum bazooka and a simple model for a Helmholtz resonator, showing that the PIF becomes decisive to compensate the group velocities involved in a highly localized excitation and to achieve subwavelength resolution.

description: To quantify spatial protein-protein proximity (colocalization) in fluorescence microscopic images, cross-correlation and autocorrelation functions were decomposed into fast and slowly decaying components. The fast component results from clusters of proteins specifically labeled and the slow one from background/image heterogeneity. We show that the calculation of the protein-protein proximity index and the correlation coefficient are more reliably determined by extracting the fast-decaying component.

description: We examine the majorization properties of general thermal-like mixed states depending on a set of parameters. Sufficient conditions which ensure the increase in mixedness, and hence of any associated entropic form, when these parameters are varied, are identified. We then discuss those exhibiting a power law distribution, showing that they can be characterized by two distinct mixing parameters, one associated with temperature and the other with the non-extensivity index q. Illustrative numerical results are also provided.

description: Data is collected everywhere in our world; however, it often is noisy and incomplete. Different sources of data may have different characteristics, quality levels, or come from dynamic and diverse environments. This poses challenges for both humans who want to gain insights from data and machines which are learning patterns from data. How can we leverage the diversity of data across domains to enhance our understanding and decision-making? In this thesis, we address this question by proposing novel methods and applications that use multiple domains as more holistic sources of information for both human and machine learning tasks. For example, to help human operators understand environmental dynamics, we show the detection and localization of distribution shifts to problematic features, as well as how interpretable distributional mappings can be used to explain the differences between shifted distributions. For robustifying machine learning, we propose a causal-inspired method to find latent factors that are robust to environmental changes and can be used for counterfactual generation or domain-independent training; we propose a domain generalization framework that allows for fast and scalable models that are robust to distribution shift; and we introduce a new dataset based on human matches in StarCraft II that exhibits complex and shifting multi-agent behaviors. We showcase our methods across various domains such as healthcare, natural language processing (NLP), computer vision (CV), etc. to demonstrate that learning from data across domains can lead to more faithful representations of data and its generating environments for both humans and machines.

Semiconductor saturable absorbers for ultrafast THz signals

description: We demonstrate saturable absorber behavior of n-type semiconductors GaAs, GaP and Ge in THz frequency range at room temperature using nonlinear THz spectroscopy. The saturation mechanism is based on a decrease in electron conductivity of semiconductors at high electron momentum states, due to conduction band nonparabolicity and scattering into satellite valleys in strong THz fields. Saturable absorber parameters, such as linear and non-saturable transmission, and saturation fluence, are extracted by fits to a classic saturable absorber model. Further, we observe THz pulse shortening, and an increase of the group refractive index of the samples at higher THz pulse peak fields.
