description: With the almost forty year existence of the Long-term Ecological Research (LTER) Network and other networks worldwide, a diverse array of long-term observational and experimental data is becoming increasingly available. A number of data repositories are making the data accessible and the accompanying detailed metadata allow meaningful reuse, repurpose and integration with other data. However, in synthesis research the largest time investment is still in discovering, cleaning and combining primary datasets until all data are completely understood and converted to a similar format. There are two approaches to achieving this data regularity: a) to prescribe the format before data collection starts, or b) to convert primary data into a flexible standard format for reuse. Prescribed formats have rarely been successful due to a wide range of ecosystems, original research questions and varying sampling methods. Hence, we took the second approach: define a flexible intermediate data model, and convert primary data. In the context of the Environmental Data Initiative’s data repository, this allows to maintain the original data format, which is most convenient for answering the original research questions, add a conversion script in R to reformat the data into the intermediary format and make this available to synthesis research as Level 1 datasets. This pre-harmonization step may be accomplished by data managers because the dataset still contains all original information without any aggregation or science question specific decisions for data omission or cleaning. Although the data are still distributed into distinct datasets, they can easily be discovered and converted into other formats.

description: A finite-temperature density functional approach to describe the properties of parahydrogen in the liquid-vapor coexistence region is presented. The first proposed functional is zero-range, where the density-gradient term is adjusted so as to reproduce the surface tension of the liquid-vapor interface at low temperature. The second functional is finite-range and, while it is fitted to reproduce bulk pH2 properties only, it is shown to yield surface properties in good agreement with experiments. These functionals are used to study the surface thickness of the liquid-vapor interface, the wetting transition of parahydrogen on a planar Rb model surface, and homogeneous cavitation in bulk liquid pH2.

description: We develop, analyze, and evaluate a novel, supervised, specific-to-general learner for a simple temporal logic and use the resulting algorithm to learn visual event definitions from video sequences. First, we introduce a simple, propositional, temporal, event-description language called AMA that is sufficiently expressive to represent many events yet sufficiently restrictive to support learning. We then give algorithms, along with lower and upper complexity bounds, for the subsumption and generalization problems for AMA formulas. We present a positive-examples--only specific-to-general learning method based on these algorithms. We also present a polynomial-time--computable ``syntactic'' subsumption test that implies semantic subsumption without being equivalent to it. A generalization algorithm based on syntactic subsumption can be used in place of semantic generalization to improve the asymptotic complexity of the resulting learning algorithm. Finally, we apply this algorithm to the task of learning relational event definitions from video and show that it yields definitions that are competitive with hand-coded ones.

description: We have carried out an HI stacking analysis of a volume-limited sample of ~5000 galaxies with imaging and spectroscopic data from GALEX and the Sloan Digital Sky Survey, which lie within the current footprint of the Arecibo Legacy Fast ALFA (ALFALFA) Survey. Our galaxies are selected to have stellar masses greater than 10^10 Msun and redshifts in the range 0.0252.6 and with light profiles that are well fit by a De Vaucouleurs model. We then stack HI line spectra extracted from the ALFALFA data cubes at the 3-D positions of the galaxies from these two samples in bins of stellar mass, stellar mass surface density, central velocity dispersion, and NUV-r colour. We use the stacked spectra to estimate the average HI gas fractions M_HI/M_* of the galaxies in each bin. Our main result is that the HI content of a galaxy is not influenced by its bulge. The average HI gas fractions of galaxies in both our samples correlate most strongly with NUV-r colour and with stellar surface density. The relation between average HI fraction and these two parameters is independent of concentration index C. We have tested whether the average HI gas content of bulge-dominated galaxies on the red sequence, differs from that of late-type galaxies on the red sequence. We find no evidence that galaxies with a significant bulge component are less efficient at turning their available gas reservoirs into stars. This result is in contradiction with the "morphological quenching" scenario proposed by Martig et al. (2009).

Effect of short- and long-range scattering in the conductivity of graphene: Boltzmann approach vs tight-binding calculations

description: We present a comparative study of the density dependence of the conductivity of graphene sheets calculated in the tight-binding (TB) Landauer approach and on the basis of the Boltzmann theory. The TB calculations are found to give the same density dependence of the conductivity, $σ\sim n$, for short-range and long-range Gaussian scatterers. In the case of short-range scattering the TB calculations are in agreement with the predictions of the Boltzmann theory going beyond the Born approximation, but in qualitative and quantitative disagreement with the standard Boltzmann approach within the Born approximation, predicting $σ= $ const. Even for the long-range Gaussian potential in a parameter range corresponding to realistic systems the standard Boltzmann predictions are in quantitative and qualitative disagreement with the TB results. This questions the applicability of the standard Boltzmann approach within the Born approximation, commonly used for the interpretation of the results of experimental studies of the transport in graphene.

description: In recent years there has been a considerable increase in the publishing of textbooks and monographs covering what was formerly known as random or irregular deterministic motion, now named by the more fashionable term of deterministic chaos. There is still substantial interest in a matter that is included in many graduate and even undergraduate courses on classical mechanics. Based on the Hamiltonian formalism, the main objective of this article is to provide, from the physicist's point of view, an overall and intuitive review of this broad subject (with some emphasis on the KAM theorem and the stability of planetary motions) which may be useful to both students and instructors.

The wide spectral coverage of this recorder, in the 650-20 MHz range, permits an analysis of the radio bursts from the base of the Solar Corona to 2 Solar Radii; it thus facilitates the association of radio activity with other types of solar energetic phenomena. Furthermore the ARTEMIS-IV1, high time resolution (1/100 sec) in the 450-270 MHz range, makes possible the detection and analysis of the fine structure which most of the major radio events exhibit.

Exploring mitochondrial DNA abnormalities in HIV-exposed uninfected children diagnosed with autism spectrum disorder : a case control study
Creators: name: Budd, Matthew
Publisher: name: University of British Columbia
Year: 2016

description: Background: Antiretroviral therapy has reduced mother-to-child HIV transmission from 25-40% to less than 2%. Thus, increasing numbers of HIV-exposed uninfected (HEU) children are being born with perinatal exposure to antiretrovirals. Recently, a Canadian HIV clinic noticed a high prevalence of autism spectrum disorder (ASD) in HEU children. This prompted our analysis of HEU children enrolled in the pan-Canadian Children & Women AntiRetrovirals & Markers of Aging (CARMA) cohort study. Significant differences in mitochondrial DNA to nuclear DNA ratio (mtDNA content) have been observed in ASD children and HEUs as a potential marker for mitochondrial dysfunction, which has been theorized as a possible mechanism underlying abnormal neurodevelopment. We hypothesized that HEU children with ASD would have significantly different leukocyte mtDNA content than HEU children without ASD and/or HUU children with and without ASD. Methods: CARMA HEU children with ASD (n=14) were matched 1:3 on age, sex, and ethnicity to HEU children without ASD (n=42), HUU anonymous controls (n=42), and HUU children with ASD in the BC Autism Spectrum Interdisciplinary Research (ASPIRE) program (n=42). Non-ASD HUU siblings of ASD children (n=9) were also studied and grouped with the HUU controls for the purposes of analyses (n=51 total). MtDNA content was assessed using qPCR. Results: Among 299 HEU children in CARMA, 14 (4.7%) were diagnosed with ASD, substantially (>3-fold) above North American prevalence estimates (1.5%). HEU children with ASD had higher mtDNA content (median[interquartile range]: 163[150–179]) than non-ASD HEUs (115[91–153], p=0.02), HUUs with ASD (110[99–132], p=0.0001), and HUU controls (100[73–121], p<0.0001). Non-autistic HEU children and ASD children with no HIV/cART exposure had higher mtDNA content than controls (p=0.004 and p=0.03, respectively), but did not significantly differ from each other (p=0.2). Conclusions: Our results suggest a possible cumulative association between elevated leukocyte mtDNA content and both HEU and ASD status. This may implicate mitochondrial dysfunction as a contributor to the high ASD prevalence in our cohort. It is unclear if this effect is modulated by exposure to antiretrovirals or maternal HIV but it is consistent with studies suggesting increased mtDNA content as an adaptive mechanism to mitochondrial dysfunction.

Towards Adjustable Autonomy for the Real World

description: Adjustable autonomy refers to entities dynamically varying their own autonomy, transferring decision-making control to other entities (typically agents transferring control to human users) in key situations. Determining whether and when such transfers-of-control should occur is arguably the fundamental research problem in adjustable autonomy. Previous work has investigated various approaches to addressing this problem but has often focused on individual agent-human interactions. Unfortunately, domains requiring collaboration between teams of agents and humans reveal two key shortcomings of these previous approaches. First, these approaches use rigid one-shot transfers of control that can result in unacceptable coordination failures in multiagent settings. Second, they ignore costs (e.g., in terms of time delays or effects on actions) to an agent's team due to such transfers-of-control. To remedy these problems, this article presents a novel approach to adjustable autonomy, based on the notion of a transfer-of-control strategy. A transfer-of-control strategy consists of a conditional sequence of two types of actions: (i) actions to transfer decision-making control (e.g., from an agent to a user or vice versa) and (ii) actions to change an agent's pre-specified coordination constraints with team members, aimed at minimizing miscoordination costs. The goal is for high-quality individual decisions to be made with minimal disruption to the coordination of the team. We present a mathematical model of transfer-of-control strategies. The model guides and informs the operationalization of the strategies using Markov Decision Processes, which select an optimal strategy, given an uncertain environment and costs to the individuals and teams. The approach has been carefully evaluated, including via its use in a real-world, deployed multi-agent system that assists a research group in its daily activities.

Diagnosing Circumstellar Debris Disks

Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)

description: (Abridged) A numerical model of a circumstellar debris disk is developed and applied to observations of the circumstellar dust orbiting beta Pictoris. The model accounts for the rates at which dust is produced by collisions among unseen planetesimals, and the rate at which dust grains are destroyed due to collisions. The model also accounts for the effects of radiation pressure, which is the dominant perturbation on the disk's smaller but abundant dust grains. Solving the resulting system of rate equations then provides the dust abundances versus grain size and over time. Those solutions also provide the dust grains' collisional lifetime versus grain size, and the debris disk's optical depth and surface brightness versus distance from the star. Comparison to observations then yields estimates of the unseen planetesimal disk's radius, and the rate at which the disk sheds mass due to planetesimal grinding. The model is then applied to optical observations of the edge-on dust disk orbiting beta Pictoris, and good agreement is achieved when the unseen planetesimal disk is broad, with 75

description: We demonstrate the lossless state-selective detection of a single rubidium 87 atom trapped in an optical tweezer. This detection is analogous to the one used on trapped ions. After preparation in either a dark or bright state, we probe the atom internal state by sending laser light that couples an excited state to the bright state only. The laser induced fluorescence is collected by a high numerical aperture lens. The single-shot fidelity of the detection is 98.6(0.2) % and is presently limited by the dark count noise of the detector. The simplicity of this method opens new perspectives in view of applications to quantum manipulations of neutral atoms.

We use ferromagnetically coupled ([Ni/Co]xn)Ni multilayers, and Py-based, symmetric double exchange-biased spin-valves (DEBSVs) containing inserts of ferromagnetically coupled ([Co/Ni]xn)Co or ([Ni/Co]xn)Ni multilayers, to derive Co/Ni interface specific resistances AR(Co/Ni)(Up) = 0.03 (+0.02)(-0.03) f-ohm-m^2 and AR(Co/Ni)(down) = 1.00 +/- 0.07 f-ohm-m^2, and interface spin-flipping parameter delta(Co/Ni) = 0.35 +/- 0.05. The specific resistances are consistent with our no-free-parameter calculations for an interface thickness between 2 and 4 monolayers (ML) that is compatible with expectations.

description: We determine the fundamental parameters of SPB and Beta Cep candidate stars observed by the Kepler satellite mission and estimate the expected types of non-radial pulsators by comparing newly obtained high-resolution spectra with synthetic spectra computed on a grid of stellar parameters assuming LTE and check for NLTE effects for the hottest stars. For comparison, we determine Teff independently from fitting the spectral energy distribution of the stars obtained from the available photometry. We determine Teff, log(g), micro-turbulent velocity, vsin(i), metallicity, and elemental abundance for 14 of the 16 candidate stars, two of the stars are spectroscopic binaries. No significant influence of NLTE effects on the results could be found. For hot stars, we find systematic deviations of the determined effective temperatures from those given in the Kepler Input Catalogue. The deviations are confirmed by the results obtained from ground-based photometry. Five stars show reduced metallicity, two stars are He-strong, one is He-weak, and one is Si-strong. Two of the stars could be Beta Cep/SPB hybrid pulsators, four SPB pulsators, and five more stars are located close to the borders of the SPB instability region.

An Analysis of Phase Transition in NK Landscapes

Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)
subject: FOS: Computer and information sciences

description: In this paper, we analyze the decision version of the NK landscape model from the perspective of threshold phenomena and phase transitions under two random distributions, the uniform probability model and the fixed ratio model. For the uniform probability model, we prove that the phase transition is easy in the sense that there is a polynomial algorithm that can solve a random instance of the problem with the probability asymptotic to 1 as the problem size tends to infinity. For the fixed ratio model, we establish several upper bounds for the solubility threshold, and prove that random instances with parameters above these upper bounds can be solved polynomially. This, together with our empirical study for random instances generated below and in the phase transition region, suggests that the phase transition of the fixed ratio model is also easy.

description: We report spectroscopic observations for 19 $δ$\,Sct candidates observed by the {\it Kepler} satellite both in long and short cadence mode. For all these stars, by using spectral synthesis, we derive the effective temperature, the surface gravity and the projected rotational velocity. An equivalent spectral type classification has been also performed for all stars in the sample. These determinations are fundamental for modelling the frequency spectra that will be extracted from the {\it Kepler} data for asteroseismic inference. For all the 19 stars, we present also periodograms obtained from {\it Kepler} data. We find that all stars show peaks in both low- ($γ$\,Dor; g mode) and high-frequency ($δ$\,Sct; p mode) regions. Using the amplitudes and considering 5\,c/d as a boundary frequency, we classified 3 stars as pure $γ$\,Dor, 4 as $γ$\,Dor\,-\,$δ$\ hybrid, Sct, 5 as $δ$\,Sct\,-\,$γ$\,Dor hybrid, and 6 as pure $δ$\,Sct. The only exception is the star KIC\,05296877 which we suggest could be a binary.

description: For a large class of space and time-dependent warped geometries we find the general solution of the 6-dimensional Einstein-Gauss-Bonnet equations in the presence of p-form matter fields. This is done under two conditions on the matter sector which we show impose the integrability of the full system. Solutions are classified and known black hole limits are found. It is shown that Lovelock gravity restricts drastically the possible horizon geometries and allowed matter sources. In fact, we show that if we allow only for solutions of asymptotically flat falloff behaviour, and no fine-tuning of coupling constants, then the only permissible black hole is that of Boulware-Deser with electromagnetic charge. The situation of 6 dimensional Lovelock gravity is therefore almost identical to 4 dimensional General Relativity. The gravitational horizon constraints lead us to find static solutions involving 3-form matter fields in anti de-Sitter space which are also new to General Relativity along with other cosmological and black string type of solutions.

Online participatory systems : a case study of a web platform for public consultation
Creators: name: Castro Miravalles, Claudia Maria
Publisher: name: University of British Columbia
Year: 2016

description: The aim of the study was to address the issues discussed by scholars that refer to the potential and the challenges of the use of online participatory methods, and contextualize them in a case study of a web platform for public consultation. To accomplish this, first a framework was set up by conducting a literature review. This study contrasts some of the theories described in the academic literature with the empirical results of this study. Using a mixed methods approach, an online survey (N=118) and phone interviews (N=23) were conducted. The survey and interview addressed issues of satisfaction with the current experience of participating online, trade-off between transparency and privacy, governance involvement and familiarity with technology in the context of online public consultation, in the hope to learn more regarding the concerns that users have about potentially replacing more traditional methods of consultation with online methods. Based on the experience of the participants of this study, we were able to identify some of the elements that increase and decrease satisfaction when participating in public consultation online, which seems to be critical in guiding the efforts of increasing online engagement. It was also found that participants prefer features such as summary tables, graphs and pictures when presented data related to the topic consulted, and that they value having options to providing feedback on a participatory web platforms. Finally, we discuss the possibility of further research with the aims of providing participants the opportunities they look for to engage in a more nuanced way. Although this research sheds light on online behavior, it also demonstrates that this is still a field that constantly requires exploration as the interaction of internet users with participatory platforms evolves. We think that understanding how theory and practice coming into play in an empirical scenario of a public consultation web platform could help online platforms and mechanisms to not only improve online participants’ experience, but most importantly, to focus on ways to achieve the larger goals of public consultation via the Internet.
Universal topological phase of 2D stabilizer codes

description: Two topological phases are equivalent if they are connected by a local unitary transformation. In this sense, classifying topological phases amounts to classifying long-range entanglement patterns. We show that all 2D topological stabilizer codes are equivalent to several copies of one universal phase: Kitaev's topological code. Error correction benefits from the corresponding local mappings.

Expert-Guided Subgroup Discovery: Methodology and Application

Publisher: name: arXiv
Year: 2011
Subjects: subject: Artificial Intelligence (cs.AI)

description: This paper presents an approach to expert-guided subgroup discovery. The main step of the subgroup discovery process, the induction of subgroup descriptions, is performed by a heuristic beam search algorithm, using a novel parametrized definition of rule quality which is analyzed in detail. The other important steps of the proposed subgroup discovery process are the detection of statistically significant properties of selected subgroups and subgroup visualization: statistically significant properties are used to enrich the descriptions of induced subgroups, while the visualization shows subgroup properties in the form of distributions of the numbers of examples in the subgroups. The approach is illustrated by the results obtained for a medical problem of early detection of patient risk groups.
Local solutions to a global problem? : Canadian municipal policy responses to climate change
Creators: name: Schwartz, Elizabeth
Publisher: name: University of British Columbia
Year: 2016

description: Urbanization and global warming are two of the most pressing issues facing humanity over the next 50 years. Why do some local governments enact more climate change mitigation policies than others? What makes some cities leaders in urban sustainability, while others lag far behind? Over the past decade, global climate change negotiations have repeatedly failed to produce binding commitments and robust responses by national governments. These failures have led academics and practitioners to put increasing emphasis on the potential for sub-national governments, including cities, to undertake commitments that might substitute for national action on climate change. Applying concepts from the comparative public policy literature to the study of urban politics, this dissertation puts forward and tests a new theory to explain variation in Canadian cities’ climate change policy. I find that political economy factors reduce the likelihood that cities will adopt climate change policy that will significantly reduce greenhouse gas emissions, but the presence of independent municipal environment departments makes the adoption of such policy more likely. This dissertation employs a systematic and explicit process tracing methodology. It examines the decision-making of four Canadian cities (Brampton, Toronto, Winnipeg and Vancouver) across four policy areas (landfill gas management, fleet services, cycling infrastructure and building standards). The analysis is based on data gathered from primary and secondary sources and expert interviews with over 70 local politicians, bureaucrats, journalists, and NGO and business representatives. This dissertation argues that cities cannot solve the climate change challenge on their own, but knowledge of the dynamics of climate change mitigation policy adoption at the local level may permit scholars and practitioners to increase the effectiveness of municipal governments’ climate change policy choices.
title: The Friendzone: Real and imagined dynamics of romantic rejection in cross-sex friendships
Creators: name: Zibell, Hannah Deborah
Publisher: name: University of Kent
Year: 2025

description: Cross-sex friendships are historically novel and consequently less well understood than same-sex friendships, both by society and the individuals within them. When these friendships are between heterosexual men and women, romantic interest is a frequent challenge. One manifestation of this challenge is the friendzone, that is, romantic interest within a cross-sex friendship that is rejected by the cross-sex friend, which has become increasingly salient in public awareness in the past three decades. Online discourse on the friendzone tends to describe it as gendered: women are portrayed as the friendzoners (i.e., those who friendzone) and men as the friendzonees (i.e., those who get friendzoned). This gendered conceptualisation of the friendzone has been noted by feminist critics who have connected the friendzone construct to sexism, misogyny, and rape culture. However, so far, no empirical research has investigated the commonness of heterosexual friendzone experiences, the perceptions of the friendzone and whether beliefs about the friendzone are associated with sexist or antifeminist ideology. This thesis presents seven studies that investigate friendzone experiences among heterosexual men and women, general perceptions of the friendzone, and associations with sexist ideologies, specifically ambivalent sexism and rape myth acceptance. Findings from these studies suggest that (a) the friendzone is experienced as gendered with men reporting more experiences as friendzonees and women as friendzoners; (b) perceptions of the friendzone are also gendered; (c) the belief that women are predominantly the friendzoners and men the friendzonees in cross-sex friendships is not reliably associated with sexist ideology; (d) though not associated with individual differences in sexism, beliefs about the friendzone are distorted insofar as people believe it is more commonly experienced, and more gendered, than is evident from first-person accounts; (d) men’s belief in the degree to which the friendzone is gendered are more exaggerated than women’s; and (e) though sexist vi ideology is not associated with beliefs about the frequency of friendzone experiences, it is associated with beliefs that women are causally responsible for them. The implications of these findings for research, the public and feminist discourse of the friendzone, perceptions of cross-sex friendships, and methodological limitations are discussed.

Evolutionary Tracks of Individual Quasars in the Mass-Luminosity Plane

description: Previous work on the quasar mass-luminosity plane indicates the possibility that quasars of the same central black hole mass might follow a common evolutionary track, independent of the properties of the host galaxy. We consider two simple models for the evolution of individual quasars. Requiring these tracks to lie within the observed quasar locus at all redshifts strongly constrains the model parameters, but does allow some solutions. These solutions include a family of tracks with similar shape but different initial masses that might match the observed quasar distributions at all redshifts z < 2.0. This family of solutions is characterized by short (1-2 Gyr) lifetimes, a duty cycle in which the quasar is on at least 25% of the time, and a rapid decline in Eddington ratio, perhaps with L/L_Edd ~ t^-6 or steeper.
