Distributed organisations for Collaborative Research

Subjects: science communication, publishing, plan s, Web

description: The scientific community today operates on a paradigm of scientific communication that dates back to the early 17th century. The Web was first and foremost created with the intention to improve cooperation among scientist and to enable coordination of a complex scientific projects. Unfortunately it was then rapidly co-opted by publishing companies and for-profit business models instead of ensuring it to remain an open resource for scientists and society at large.

Both the hierarchical, outdated nature of how we operate to this date in academic institutions and the demands for metrics to measure research output by public funders that mostly are  generated by publishers leads to a vicious circle that is hard to escape.

The presentation highlights the historical roots of this problem and how open access movements begun to overcome it.

The distributed Web is poised to enable large scale coordination and cooperation among scientist and citizens, reaching beyond nations and even continents to tackle the world most pressing challenges. The talk thus proposes how we may integrate next generation web technologies that enable self sovereign publishing.

Year: 2023
Subjects: iTHRIV

description: RATIONALE
We aimed to create and critically examine models to predict the risk of hospitalization at the time of COVID19 diagnosis.

PARTICIPANTS
We used the N3C dataset to identify patients with COVID19 from the start of the pandemic until 5/11/2023. We excluded patients younger than 16 years, patients contributed by a data partner with >10% missing geographic data, and patients who were hospitalized on the calendar day of their test.

OUTCOMES
Our primary outcome was hospitalization within the 16 days following a COVID19 diagnosis.

MEASURES 
We included demographics, comorbid conditions, medication exposures, and zip-code level social determinants of health.

MODEL DEVELOPMENT
We compared two methods: a gradient boosted tree (GBT) ensemble model (LightGBM, Redmond, Washington) and machine learning optimized sparse scorecard model (FasterRISK, Durham, North Carolina). We used 80% of the data for training and 20% of the data for model validation. 

RESULTS
Our final training cohort consisted of 3.6 million patients with a 1.7% rate of hospitalization. Five data partners were excluded for >10% missing patient geographic data. The GBT model had a validation set AUROC of 0.773 and a brier skill score of 0.021. The sparse decision rule performance was slightly lower with a validation AUROC 0.735 and a brier skill score of 0.013. Performance of the GBT model varied across subgroups. Across gender the model had a validation set AUROC of 0.770 in men and 0.777 in women. Across patient self-reported race, the model had an AUROC on 0.787 in white subjects and 0.748 in Black subjects. 

CONCLUSIONS
Hospitalization can be predicted with reasonable discrimination and modest overall accuracy. Most of the identified risk factors comport with accepted risk factors. Identified social determinants are likely proxies for latent causes such as social vulnerability, structural racism, and historical injustice that continue to affect the health of people today.
Phylogenetics and molecular evolution of Alismatales based on whole plastid genomes
Creators: name: Ross, Thomas Gregory
Publisher: name: University of British Columbia
Year: 2015

description: The order Alismatales is a mostly aquatic group of monocots that displays substantial morphological and life history diversity, including the seagrasses, the only land plants that have re-colonized marine environments. Past phylogenetic studies of the order have either considered a single gene with dense taxonomic sampling, or several genes with thinner sampling. Despite substantial progress based on these studies, multiple phylogenetic uncertainties still remain concerning higher-order phylogenetic relationships. To address these issues, I completed a near-genus level sampling of the core alismatid families and the phylogenetically isolated family Tofieldiaceae, adding these new data to published sequences of Araceae and other monocots, eudicots and ANITA-grade angiosperms. I recovered whole plastid genomes (plastid gene sets representing up to 83 genes per taxa) and analyzed them using maximum likelihood and parsimony approaches. I recovered a well supported phylogenetic backbone for most of the order, with all families supported as monophyletic, and with strong support for most inter- and intrafamilial relationships. A major exception is the relative arrangement of Araceae, core alismatids and Tofieldiaceae; although most analyses recovered Tofieldiaceae as the sister-group of the rest of the order, this result was not well supported. Different partitioning schemes used in the likelihood analyses had little effect on patterns of clade support across the order, and the parsimony and likelihood results were generally highly congruent. I also used the inferred phylogeny of Alismatales to study the loss of the mostly plastid-encoded NADH dehydrogenase enzyme complex in the order. This enzyme is hypothesized to be involved in mitigating photooxidative stress by inducing chlororespiration. The inclusion or exclusion of ndh pseudogenes had little impact on the main phylogenetic results. Previous work hypothesized three independent losses/pseudogenization events within the core alismatids, which I confirmed here. I also inferred an additional loss in Tofieldiaceae, the first example in unsubmerged species of Alismatales. The repeated loss of plastid NADH dehydrogenase may spur future research into the physiological bases of the loss.

description: We show that locally every beta-integrable (2,n)-Segre structure can be reduced to a torsion-free S^1*GL(n,R)-structure. This is done by observing that such reductions correspond to sections with holomorphic image of a certain `twistor bundle'. For the homogeneous (2,n)-Segre structure on the oriented 2-plane Grassmannian, the reductions are shown to be in one-to-one correspondence with the smooth quadrics in CP^{n+1} without real points.

The Evolution of Stock Market Efficiency in the US: A Non-Bayesian Time-Varying Model Approach

Year: 2012
Subjects: subject: Statistical Finance (q-fin.ST)
subject: FOS: Economics and business

description: A non-Bayesian time-varying model is developed by introducing the concept of the degree of market efficiency that varies over time. This model may be seen as a reflection of the idea that continuous technological progress alters the trading environment over time. With new methodologies and a new measure of the degree of market efficiency, we examine whether the US stock market evolves over time. In particular, a time-varying autoregressive (TV-AR) model is employed. Our main findings are: (i) the US stock market has evolved over time and the degree of market efficiency has cyclical fluctuations with a considerably long periodicity, from 30 to 40 years; and (ii) the US stock market has been efficient with the exception of four times in our sample period: during the long-recession of 1873-1879; the recession of 1902-1904; the New Deal era; and the recession of 1957-1958 and soon after it. It is then shown that our results are partly consistent with the view of behavioral finance.

A categorical foundation for Bayesian probability

description: Given two measurable spaces $H$ and $D$ with countably generated $σ$-algebras, a perfect prior probability measure $P_H$ on $H$ and a sampling distribution $S: H \rightarrow D$, there is a corresponding inference map $I: D \rightarrow H$ which is unique up to a set of measure zero. Thus, given a data measurement $μ: 1 \rightarrow D$, a posterior probability $\widehat{P_H}= I \circ μ$ can be computed. This procedure is iterative: with each updated probability $P_H$, we obtain a new joint distribution which in turn yields a new inference map $I$ and the process repeats with each additional measurement. The main result uses an existence theorem for regular conditional probabilities by Faden, which holds in more generality than the setting of Polish spaces. This less stringent setting then allows for non-trivial decision rules (Eilenberg--Moore algebras) on finite (as well as non finite) spaces, and also provides for a common framework for decision theory and Bayesian probability.

description: We show that K3 surfaces with non-symplectic automorphisms of prime order can be used to construct new compact irreducible G2-manifolds. This technique was carried out in detail by Kovalev and Lee for non-symplectic involutions. We use Chen-Ruan orbifold cohomology to determine the Hodge diamonds of certain complex threefolds, which are the building blocks for this approach.

CMCMPI : Compose-Map-Configure MPI
Creators: name: Chung, Ryan Ki Sing
Publisher: name: University of British Columbia
Year: 2014

description: In order to manage the complexities of Multiple Program, Multiple Data (MPMD) program deployment to optimize for performance, we propose (CM)²PI as a specification and tool that employs a four stage approach to create a separation of concerns between distinct decisions: architecture interactions, software size, resource constraints, and function. With function level parallelism in mind, to create a scalable architecture specification we use multi-level compositions to improve re-usability and encapsulation. We explore different ways to abstract out communication from the tight coupling of MPI ranks and placement. One of the methods proposed is the flow-controlled channels which also aims at tackling the common issues of buffer limitations and termination. The specification increase compatibility with optimization tools. This enables the automatic optimization of program run time with respect to resource constraints. Together these features simplify the development of MPMD MPI programs.
On a functional contraction method

description: Methods for proving functional limit laws are developed for sequences of stochastic processes which allow a recursive distributional decomposition either in time or space. Our approach is an extension of the so-called contraction method to the space $\mathcal{C}[0,1]$ of continuous functions endowed with uniform topology and the space $\mathcal {D}[0,1]$ of càdlàg functions with the Skorokhod topology. The contraction method originated from the probabilistic analysis of algorithms and random trees where characteristics satisfy natural distributional recurrences. It is based on stochastic fixed-point equations, where probability metrics can be used to obtain contraction properties and allow the application of Banach's fixed-point theorem. We develop the use of the Zolotarev metrics on the spaces $\mathcal{C}[0,1]$ and $\mathcal{D}[0,1]$ in this context. Applications are given, in particular, a short proof of Donsker's functional limit theorem is derived and recurrences arising in the probabilistic analysis of algorithms are discussed.

Subjects: subject: Geometric Topology (math.GT)

description: We show that any smooth, closed, oriented, connected 4--manifold can be trisected into three copies of $\natural^k (S^1 \times B^3)$, intersecting pairwise in 3--dimensional handlebodies, with triple intersection a closed 2--dimensional surface. Such a trisection is unique up to a natural stabilization operation. This is analogous to the existence, and uniqueness up to stabilization, of Heegaard splittings of 3--manifolds. A trisection of a 4--manifold $X$ arises from a Morse 2--function $G:X \to B^2$ and the obvious trisection of $B^2$, in much the same way that a Heegaard splitting of a 3--manifold $Y$ arises from a Morse function $g : Y \to B^1$ and the obvious bisection of $B^1$.

Drastic fall-off of the thermal conductivity for disordered lattices in the limit of weak anharmonic interactions

description: We study the thermal conductivity, at fixed positive temperature, of a disordered lattice of harmonic oscillators, weakly coupled to each other through anharmonic potentials. The interaction is controlled by a small parameter $ε> 0$. We rigorously show, in two slightly different setups, that the conductivity has a non-perturbative origin. This means that it decays to zero faster than any polynomial in $ε$ as $ε\rightarrow 0$. It is then argued that this result extends to a disordered chain studied by Dhar and Lebowitz, and to a classical spins chain recently investigated by Oganesyan, Pal and Huse.

description: We carry out a three-loop computation that establishes the existence of scale without conformal invariance in dimensional regularization with the MS scheme in d=4-epsilon spacetime dimensions. We also comment on the effects of scheme changes in theories with many couplings, as well as in theories that live on non-conformal scale-invariant renormalization group trajectories. Stability properties of such trajectories are analyzed, revealing both attractive and repulsive directions in a specific example. We explain how our results are in accord with those of Jack & Osborn on a c-theorem in d=4 (and d=4-epsilon) dimensions. Finally, we point out that limit cycles with turning points are unlike limit cycles with continuous scale invariance.

Thermodynamic and transport properties of a holographic quantum Hall system
Creators: name: Hutchinson, Joel
Publisher: name: University of British Columbia
Year: 2014

description: We apply the AdS/CFT correspondence to study a quantum Hall system at strong coupling. Fermions at finite density in an external magnetic field are put in via gauge fields living on a stack of D5 branes in Anti-deSitter space. Under the appropriate conditions, the D5 branes blow up to form a D7 brane which is capable of forming a charge-gapped state. We add finite temperature by including a black hole which allows us to compute the low temperature entropy of the quantum Hall system. Upon including an external electric field (again as a gauge field on the probe brane), the conductivity tensor is extracted from Ohm’s law.

We explore couplings up to |β|<5. In the case of the exponential potential, we find an upper limit on $Ω_νh^2$<0.004 at 2-$σ$ level. In the case of the inverse power law potential the null coupling can be excluded with more than 2-σsignificance; the limits on the coupling are β>3 for the growing neutrino mass and β

The adventures of Nikita and Casper : high power ultraviolet lasers for precision spectroscopy
Creators: name: Altiere, Emily Elizabeth
Publisher: name: University of British Columbia
Year: 2014

description: The Optically Pumped Semiconductor Laser (OPSL) offers several advantages as a laser source for precision spectroscopy. The semiconductor gain bandwidth allows an OPSL to run continuous wave (CW) between 920 - 1154 nm and with a free running linewidth 500 kHz. High powers have been observed in OPSL, as high as 70 W. Paired with doubling crystals the wavelength range can be extended down to the ultraviolet(UV) with high power. This research presents an OPSL operating at 972 nm at 1.7 W sequentially doubled down twice to a wavelength of 243 nm at 150 mW. The linewidth is reduced by locking one OPSL to a Fabry-Poret stabilization cavity and then the relative linewidth was measured between two OPSL's locked together. The linewidth is determined to be 87 kHz, dominated mostly by technical noise. This laser is set to be used for cryogenic hydrogen spectroscopy and precision measurements of the Lamor precessional frequency of ¹²⁹Xe when it is used as a comagnetometer for measuring the electrical dipole moment (EDM) of the neutron.

description: We propose a method called ideal regression for approximating an arbitrary system of polynomial equations by a system of a particular type. Using techniques from approximate computational algebraic geometry, we show how we can solve ideal regression directly without resorting to numerical optimization. Ideal regression is useful whenever the solution to a learning problem can be described by a system of polynomial equations. As an example, we demonstrate how to formulate Stationary Subspace Analysis (SSA), a source separation problem, in terms of ideal regression, which also yields a consistent estimator for SSA. We then compare this estimator in simulations with previous optimization-based approaches for SSA.

description: We consider the problem of estimating neural activity from measurements of the magnetic fields recorded by magnetoencephalography. We exploit the temporal structure of the problem and model the neural current as a collection of evolving current dipoles, which appear and disappear, but whose locations are constant throughout their lifetime. This fully reflects the physiological interpretation of the model. In order to conduct inference under this proposed model, it was necessary to develop an algorithm based around state-of-the-art sequential Monte Carlo methods employing carefully designed importance distributions. Previous work employed a bootstrap filter and an artificial dynamic structure where dipoles performed a random walk in space, yielding nonphysical artefacts in the reconstructions; such artefacts are not observed when using the proposed model. The algorithm is validated with simulated data, in which it provided an average localisation error which is approximately half that of the bootstrap filter. An application to complex real data derived from a somatosensory experiment is presented. Assessment of model fit via marginal likelihood showed a clear preference for the proposed model and the associated reconstructions show better localisation.

description: A real 3-manifold is a smooth 3-manifold together with an orientation preserving smooth involution, called a real structure. In this article we study open book decompositions on smooth real 3-manifolds that are compatible with the real structure. We call them real open book decompositions. We show that each real open book carries a real contact structure and two real contact structures supported by the same real open book decomposition are equivariantly isotopic. We also show that every real contact structure on a closed 3-dimensional real manifold is supported by a real open book. Finally, we conjecture that two real open books on a real contact manifold supporting the same real contact structure are related by positive real stabilizations and equivariant isotopy and that the Giroux correspondence applies to real manifolds as well namely that there is a one to one correspondence between the real contact structures on a real 3-manifold up to equivariant contact isotopy and the real open books up to positive real stabilization. Meanwhile, we study some examples of real open books and real Heegaard decompositions in lens spaces.

description: The number of excursions (finite paths starting and ending at the origin) having a given number of steps and obeying various geometric constraints is a classical topic of combinatorics and probability theory. We prove that the sequence $(e^{\mathfrak{S}}_n)_{n\geq 0}$ of numbers of excursions in the quarter plane corresponding to a nonsingular step set $\mathfrak{S} \subseteq \{0,\pm 1 \}^2$ with infinite group does not satisfy any nontrivial linear recurrence with polynomial coefficients. Accordingly, in those cases, the trivariate generating function of the numbers of walks with given length and prescribed ending point is not D-finite. Moreover, we display the asymptotics of $e^{\mathfrak{S}}_n$.

description: We introduce an operation on modules over an $F$-finite ring of characteristic $p$. We call this operation \emph{tight interior}. While it exists more generally, in some cases this operation is equivalent to the Matlis dual of tight closure. Moreover, the interior of the ring itself is simply the big test ideal. We directly prove, without appeal to tight closure, results analogous to persistence, colon capturing, and working modulo minimal primes, and we begin to develop a theory dual to phantom homology. Using our dual notion of persistence, we obtain new and interesting transformation rules for tight interior, and so in particular for the test ideal, which complement the main results of a recent paper of the second author and K. Tucker. Using our theory of phantom homology, we prove a vanishing theorem for maps of Ext. We also compare our theory to M. Blickle's notion of Cartier modules, and in the process, we prove new existence results for Blickle's test submodule. Finally, we apply the theory we developed to the study of test ideals in non-normal rings, proving that the finitistic test ideal coincides with the big test ideal in some cases.

description: Cultural competence resides at the core of undergraduate and postgraduate medical and health professional education. The evolution of studies on cultural competence has resulted in the existence of multiple theoretical frameworks and models, each emphasising certain elements of culturally appropriate care, but generally lacking in providing a coherent and systematic approach to teaching this subject. Following a meta-ethnographic approach, a systematic search of five databases was undertaken to identify relevant articles published between 1990 and 2022. After citation searching and abstract and full article screening, a consensus was reached on 59 articles for final inclusion. Key constructs and concepts of cultural competence were synthesised and presented as themes, using the lens of critical theory. Three key themes were identified: competences; roles and identities; structural competency. Actionable concepts and themes were incorporated into a new transformative ACT cultural model that consists of three key domains: activate consciousness, connect relations, and transform to true cultural care. This critical review provides an up-to-date synthesis of studies that conceptualise cultural competence frameworks and models in international medical and healthcare settings. The ACT cultural model provides a set of guiding principles for culturally appropriate care, to support high-quality educational interventions.

description: The influence of additional information on the decision making of agents, who are interacting members of a society, is analyzed within the mathematical framework based on the use of quantum probabilities. The introduction of social interactions, which influence the decisions of individual agents, leads to a generalization of the quantum decision theory developed earlier by the authors for separate individuals. The generalized approach is free of the standard paradoxes of classical decision theory. This approach also explains the error-attenuation effects observed for the paradoxes occurring when decision makers, who are members of a society, consult with each other, increasing in this way the available mutual information. A precise correspondence between quantum decision theory and classical utility theory is formulated via the introduction of an intermediate probabilistic version of utility theory of a novel form, which obeys the requirement that zero-utility prospects should have zero probability weights.

Structured quantitative inquiry labs : developing critical thinking in the introductory physics laboratory
Creators: name: Holmes, Natasha Grace
Publisher: name: University of British Columbia

description: Many undergraduate labs engage students in experimentation without developing critical thinking or scientific reasoning skills, especially about measurement and data. In this thesis, I present a pedagogical framework for developing students' critical thinking behaviours in a first-year undergraduate physics lab. The main critical thinking behaviours assessed were for students to reflect on their data collection and analyses, iterate to improve their measurements and methods, and evaluate the experiments and theoretical models. The pedagogy uses structured comparisons between measurements and models, with a critical focus on understanding measurement and uncertainty at a conceptual level and applying the concepts to quantitative analysis of data. Implementation involved scaffolded instructions and support for reflection and iteration that was dynamically faded throughout the course. Through analysis of students' written lab materials, I evaluated their engagement in reflection, iteration, and evaluation, comparing to a previous iteration of the course that did not include the critical thinking scaffolding. Students in the new course structure not only transferred the previously scaffolded reflection and iteration behaviours to unscaffolded experiments, but also spontaneously evaluated theoretical models, which was never explicitly structured. While the previous version of the course supported students in data analysis at a procedural, 'plug-and-chug' level, the new course structure significantly improved students' critical thinking behaviours, shifted students into more expert-like epistemological frames, and improved their motivation and attitudes about experimental physics.

Steady-state simulation of reflected Brownian motion and related stochastic networks

description: This paper develops the first class of algorithms that enable unbiased estimation of steady-state expectations for multidimensional reflected Brownian motion. In order to explain our ideas, we first consider the case of compound Poisson (possibly Markov modulated) input. In this case, we analyze the complexity of our procedure as the dimension of the network increases and show that, under certain assumptions, the algorithm has polynomial-expected termination time. Our methodology includes procedures that are of interest beyond steady-state simulation and reflected processes. For instance, we use wavelets to construct a piecewise linear function that can be guaranteed to be within $\varepsilon$ distance (deterministic) in the uniform norm to Brownian motion in any compact time interval.

description: Das Schadensphänomen „Craquelé“ stellt in der Glasmalereirestaurierung ein bislang ungelöstes Problem dar. Vor allem Gläser aus der Zeit des 19. Jahrhunderts, insbesondere bernsteinfarbene, sind davon betroffen. Sie zeigen verschiedene Rissmuster in Form von oberflächlichen Risslagen mit Schollenbildung bis hin zu Tiefenrissen, die das Glas in der gesamten Stärke durchziehen. Je nach Ausprägung führen die Risssysteme zu deutlich verminderter Stabilität der Scheiben und zu veränderter Transparenz. Zur Behandlung craquelierter Gläser gibt es bislang keine tragfähigen Konzepte. Unklar ist auch, welche Ursachen das Schadensbild auslösen. Unter anderem kommt schadstoffbelastete Luft als ein gewichtiger Faktor in Frage.

Hauptgegenstand der Untersuchungen war das Jesus-Sirach-Fenster, ein großes Fenster aus dem „Welterzyklus“, des Kölner Domes. Weitere craquelierte Einzelgläser aus anderen Glasmalereibeständen des späten 19. Jahrhunderts wurden in die Untersuchungen einbezogen. Anhand originaler Gläser sollte eine Charakterisierung des Schadensbildes Craquelé erfolgen. Als reproduzierbares Probenmaterial sollten künstlich craquelierte Modellgläser entwickelt werden, um Untersuchungen zu Schadensursachen und konservatorische Versuchsreihen durchführen zu können.

Als Konservierungsmaterial sollte der Einsatz eines im Kompetenzfeld „Anorganische Materialien aus flüssigen Vorstufen“ des Fraunhofer-Instituts für Silicatforschung (ISC) entwickelten, hydroaktiven Gels (Laborbezeichnung „A18“) getestet und an die Erfordernisse zur Sicherung craquelierter Gläser angepasst werden. Das neue Festigungsmaterial, ein nanomolekular strukturierter, organisch-anorganischer Aluminiumkomplex mit glasähnlichem Brechungsindex, weist prinzipiell gute Eigenschaften für die Festigung feinster Spaltsysteme, v. a. die langen engen Risssysteme von Tiefenrissen, auf. Mit reinem Ethanol verdünnt und als niedrigviskose Lösung infiltriert, polymerisiert das Sol-Gel in den Spalten zu einem anorganischen silicatischen Gerüst und stabilisiert sie von innen her. Parallel zum Einsatz von A18 sollte auch die Verwendung von Glasfasergeweben und -vliesen als quasi unsichtbare Kaschierung craquelierter Gläser geprüft und durch die Auswahl geeigneter Materialien in Kombination mit möglichen Klebematerialien optimiert werden.
