description: In this paper we deal with the notion of semantic loss in Peer Data Management Systems (PDMS) queries. We define such a notion and we give a mechanism that discovers semantic loss in a PDMS network. Next, we propose an algorithm that addresses the problem of restoring such a loss.

description: The properties of a planetary system may be influenced by properties of the host star, such as its birth environment or age. Recently, a link has been found between a star's local phase space density in the Galaxy and the presence of a hot Jupiter: hot Jupiters are preferentially found around stars with higher local phase space densities. Using kinematic data for exoplanet hosts from Gaia EDR3, we show that the phase space density is primarily determined by a star's Galactic kinematics -- notably, its orbital velocity around the Galactic centre relative to a circular orbit. Stars on kinematically "colder" orbits have higher local phase space densities than stars on kinematically "hotter" orbits. Once this effect is accounted for, we find no evidence that hot Jupiter hosts are in higher-density regions of phase space than other stars. Younger stars are on average on colder orbits, and older stars are on average on hotter orbits, so we argue that the preference for hot Jupiter hosts to be in high-density regions reflects an age bias: hot Jupiters are more common around younger stars, before their population is reduced by tidal inspiral. Our work gives a hint of the relations that PLATO may uncover when it provides precise and accurate ages for a large number of main-sequence exoplanet hosts.

description: We analysed 337 multi-epoch optical spectra of 38 Herbig Ae/Be (HAeBe) stars to gain insights into the variability behaviour of the circumstellar (CS) atomic gas. Equivalent widths (EWs) and line fluxes of the Halpha, [OI]6300, HeI5876 and NaID lines were obtained for each spectrum; the Halpha line width at 10% of peak intensity (W10) and profile shapes were also measured and classified. The mean line strengths and relative variabilities were quantified for each star. Simultaneous optical photometry was used to estimate the line fluxes. We present a homogeneous spectroscopic database of HAeBe stars. The lines are variable in practically all stars and timescales, although 30 % of the objects show a constant EW in [OI]6300, which is also the only line that shows no variability on timescales of hours. The HeI5876 and NaID EW relative variabilities are typically the largest, followed by those in [OI]6300 and Halpha. The EW changes can be larger than one order of magnitude for the HeI5876 line, and up to a factor 4 for Halpha. The [OI]6300 and Halpha EW relative variabilities are correlated for most stars in the sample. The Halpha mean EW and W10 are uncorrelated, as are their relative variabilities. The Halpha profile changes in 70 % of the objects. The massive stars in the sample usually show more stable Halpha profiles with blueshifted self-absorptions and less variable 10% widths. Our data suggest multiple causes for the different line variations, but the [OI]6300 and Halpha variability must share a similar origin in many objects. The physical mechanism responsible for the Halpha line broadening does not depend on the amount of emission; unlike in lower-mass stars, physical properties based on the Halpha luminosity and W10 would significantly differ. Our results provide additional support to previous works that reported different physical mechanisms in Herbig Ae and Herbig Be stars.

description: The brain can be considered as a system that dynamically optimizes the structure of anatomical connections based on the efficiency requirements of functional connectivity. To illustrate the power of this principle in organizing the complexity of brain architecture, we portray the functional connectivity as diffusion on the current network structure. The diffusion drives adaptive rewiring, resulting in changes to the network to enhance its efficiency. This dynamic evolution of the network structure generates, and thus explains, modular small-worlds with rich club effects, f eatures commonly observed in neural anatomy. Taking wiring length and propagating waves into account leads to the morphogenesis of more specific neural structures that are stalwarts of the detailed brain functional anatomy, such as parallelism, divergence, convergence, super-rings, and super-chains. By showing how such structures emerge, largely independently of their specific biological realization, we offer a new conjecture on how natural and artificial brain-like structures can be physically implemented.

description: The two-color optical coherence absorption spectrum (QUIC-AB) of GaAs quantum well in the presence of a charge current is investigated. We find that the QUIC-AB depends strongly not only on the amplitude of the electron current but also on the direction of the electron current. Thus, the amplitude and the angular distribution of scattering current in the scatter process can be detected directly in real time with the QUIC-AB. The phase shift of scattered waves and the details of the scattering potential can also be determined.

description: Inspired by the ubiquity of composite filamentous networks in nature we investigate models of biopolymer networks that consist of interconnected floppy and stiff filaments. Numerical simulations carried out in three dimensions allow us to explore the microscopic partitioning of stresses and strains between the stiff and floppy fractions c_s and c_f, and reveal a non-trivial relationship between the mechanical behavior and the relative fraction of stiff polymer: when there are few stiff polymers, non-percolated stiff ``inclusions`` are protected from large deformations by an encompassing floppy matrix, while at higher fractions of stiff material the stiff network is independently percolated and dominates the mechanical response.

Integrating geochemical and microbiological information for better modeling of the N-cycle – past and present
Creators: name: Michiels, Céline Chantal
Publisher: name: University of British Columbia
Year: 2019

description: Cycling of N occurs through a multitude of microbial reactions used by microorganisms to harness energy and generate growth. These microbial reactions are the main controls on the availability of fixed-N and can often limit primary production in marine ecosystems. The microorganisms involved in the N-cycle are diverse and the metabolic pathways are further distributed across many taxa, rendering the modeling of the N-cycle complex. Indeed, models of N-cycling fall short of making robust and explicit predictions, in part due to a lack of ecophysiological information describing the relevant processes at a molecular scale. Direct ecophysiological information is obtained from process rate measurements, yet these generally lack coupled information on microbial community composition limiting their extensibility across multiple environments. This dissertation creates a new framework for the modeling of the N-cycle by measuring the rates and pathways of N-cycling in anoxic pelagic environments. This new and quantitative knowledge is incorporated into models of N-cycling to improve reconstructions of past and future N-cycle. I describe the rates and pathways of Fe-dependent NO¯₃ reduction in a ferruginous pelagic environment, analogous to the Proterozoic oceans. I then describe the nutrients status and the implications of NO¯₃ reduction through DNRA and denitrification for biological production through a flux-balance model for ancient oceans. I also study the environmental factors that influence the partitioning of N-loss between anammox and denitrification in an anoxic fjord (Saanich Inlet). A flux-balance model was built to describe the competition between anammox and denitrification based on the rates of N₂ production as well as changes in microbial community composition and ecophysiological parameters. We show that recycling of N through DNRA, rather than N-loss, dominates annual NO¯₃ reduction in Saanich Inlet, challenging current assumptions that DNRA does not need to be considered as an important pathway of N-cycling in the ocean. Overall, the work presented here offers a new and integrated approach that combines geochemical information such as nutrient profiles and process rate measurements, microbiological information such as microbial community composition, structure and functions analysis, and applies it to quantitative models that can be used to further test hypotheses about the N-cycle.
Origin and thermometry of graphites from Itapecerica supracrustal succession of the southern Sao Francisco Craton by C isotopes, X-ray diffraction, and Raman spectroscopy

description: In the mines of the Nacional de Grafite Company around Itapecerica (Minas Gerais), located in the southern Sao Francisco Craton, occurs a supracrustal succession of high-grade metamorphic rocks including quartzite, garnet-biotite gneiss, and graphite schist formed in the Palaeoproterozoic (2.0 Ga). During metamorphic processes, organic matter was progressively transformed into graphite. From four graphite samples of three different mines (two samples from high-grade metamorphic graphite schist and two generated by hydrothermal recrystallization of the graphite schist), the origin and formation temperature of this mineral was obtained by C isotopes, X-ray diffraction (XRD), and Raman spectroscopy. The values of δ13C range between −21.23 and −27.89 ‰, indicating that the source of the graphite was a primitive biogenic carbon material. High-grade metamorphic graphites show average temperatures around 729°C, while hydrothermal recrystallizated graphites (vein-graphites) show temperatures around 611°C by XRD, which correspond to granulite- to amphibolite facies conditions. The hydrothermal process with percolation of C-O-H fluids leads to a decrease in the crystal size along stacking direction (Lc(002)) when compared with the previously formed high-grade metamorphism graphites. An update of the current tectonic model about the collisional process during Rhyacian-Orosirian orogeny in the Sao Francisco Craton is proposed to insert the formation of the Itapecerica graphite-rich metasedimentary sequence.
Explosive Outflows Powered by the Decay of Non-Hierarchical Multiple Systems of Massive Stars: Orion BN/KL

description: The explosive BN/KL outflow emerging from OMC1 behind the Orion Nebula may have been powered by the dynamical decay of a non-hierarchical multiple system $\sim$500 years ago that ejected the massive stars I, BN, and source n, with velocities of about 10 to 30 km s$^{-1}$. New proper motion measurements of H$_2$ features show that within the errors of measurement, the outflow originated from the site of stellar ejection. Combined with published data, these measurements indicate an outflow age of $\sim$500 years, similar to the time since stellar ejection. The total kinetic energy of the ejected stars and the outflow is about 2 to $6 \times 10^{47}$ ergs. It is proposed that the gravitational potential energy released by the formation of a short-period binary, most likely source I, resulted in stellar ejection and powered the outflow. A scenario is presented for the formation of a compact, non-hierarchical multiple star system, its decay into an ejected binary and two high-velocity stars, and launch of the outflow. Three mechanisms may have contributed to the explosion in the gas: (i) Unbinding of the circum-cluster envelope following stellar ejection, (ii) disruption of circumstellar disks and high-speed expulsion of the resulting debris during the final stellar encounter, and (iii) the release of stored magnetic energy. Plausible proto-stellar disk end envelope properties can produce the observed outflow mass, velocity, and kinetic energy distributions. The ejected stars may have acquired new disks by fall-back or Bondi-Hoyle accretion with axes roughly orthogonal to their velocities. The expulsion of gas and stars from OMC1 may have been driven by stellar interactions.

description: This paper presents the first sub-10$μ$W, sub-0.1% total harmonic distortion (THD) sinusoidal current generator (CG) integrated circuit (IC) that is capable of 20kHz output for the bio-impedance (Bio-Z) sensing applications. To benefit from the ultra-low-power nature of near-threshold operation, a 9b pseudo-sine lookup table (LUT) is 3b $ΔΣ$ modulated in the digital domain, thus linearity burden of the digital-to-analog converter (DAC) is avoided and only a 1.29$μ$W of logic power is consumed, from a 0.5V supply and a 2.56MHz clock frequency. A half-period (HP) reset is introduced in the capacitive DAC, leading to around 30dB reduction of in-band noise by avoiding the sampling of data-dependent glitches and attenuating the kT/C noise and the non-idealities of reset switches (SW).

description: The flexibility in the structure of calmodulin (CaM) allows its binding to over 300 target proteins in the cell. To investigate the structure-function relationship of CaM, we combined methods of computer simulation and experiments based on circular dichroism (CD) to investigate the structural characteristics of CaM that influence its target recognition in crowded cell-like conditions. We developed a unique multiscale solution of charges computed from quantum chemistry, together with protein reconstruction, coarse-grained molecular simulations, and statistical physics, to represent the charge distribution in the transition from apoCaM to holoCaM upon calcium binding. Computationally, we found that increased levels of macromolecular crowding, in addition to calcium binding and ionic strength typical of that found inside cells, can impact the conformation, helicity and the EF hand orientation of CaM. Because EF hand orientation impacts the affinity of calcium binding and the specificity of CaM's target selection, our results may provide unique insight into understanding the promiscuous behavior of calmodulin in target selection inside cells.

description: BLDC motor applications require precise position and speed measurements, traditionally obtained with sensors. This article presents a method for estimating those measurements without position sensors using terminal phase voltages with attenuated spurious, acquired with a FPGA that also operates a PWM-controlled inverter. Voltages are labelled with electrical and virtual rotor states using an encoder that provides training and testing data for two three-layer ANNs with perceptron-based cascade topology. The first ANN estimates the position from features of voltages with incremental timestamps, and the second ANN estimates the speed from features of position differentials considering timestamps in an acquisition window. Sensor-based training and sensorless testing at 125 to 1,500 rpm with a loaded 8-pole-pair motor obtained absolute errors of 0.8 electrical degrees and 22 rpm. Results conclude that the overall position estimation significantly improved conventional and advanced methods, and the speed estimation slightly improved conventional methods, but was worse than in advanced ones.

description: In the microscopic world, multipartite entanglement has been achieved with various types of nanometer sized two-level systems such as trapped ions, atoms and photons. On the macroscopic scale ranging from micrometers to millimeters, recent experiments have demonstrated bipartite and tripartite entanglement for electronic quantum circuits with superconducting Josephson junctions. It remains challenging to bridge these largely different length scales by constructing hybrid quantum systems. Doing this may allow for manipulating the entanglement of individual microscopic objects separated by macroscopically large distances in a quantum circuit. Here we report on the experimental demonstration of induced coherent interaction between two intrinsic two-level states (TLSs) formed by atomic-scale defects in a solid via a superconducting phase qubit. The tunable superconducting circuit serves as a shuttle communicating quantum information between the two microscopic TLSs. We present a detailed comparison between experiment and theory and find excellent agreement over a wide range of parameters. We then use the theoretical model to study the creation and movement of entanglement between the three components of the quantum system.

Subjects: Risk Communication, Risk Perception

description: This deliverable D1.3 brings together research from the two previous Work Package (WP) 1 deliverables, that are outlined below, to discuss the gaps between the state of the art research (SOTA) and what occurs in practice in six the case study areas. The report defines concepts and processes of disaster management, discusses current operations, and suggests solutions to the gaps discovered. First, background information on the work already done in WP1 is discussed. Then, the gaps are examined in more detail, including information on how they were identified. While discussing the gaps definitions of DRM terms, current practices in case study areas, and suggestions of ways to address these gaps are also highlighted. Finally, the report provides a roadmap for future activities in RiskPACC, and how they can be used to close some of the gaps highlighted in the report. Additionally, the risk perception action gap (RPAG) is discussed in relation to the gaps and activities are suggested to close the RPAG going forward. Chapter 2 of this report provides an overview of the previous work done in WP1. This includes a summary of the results of two deliverables, D1.1 and D1.2. D1.1 provides the theoretical background on disaster resilience, vulnerability and risk perception, leading to the creation of working definitions of these concepts for RiskPACC. There is then a dicussion of the current research on operationalising the concepts. The research on both disaster resilience and risk perception highlighted the need for more bottom-up activiites and an increase in two-way communication. This SOTA research was then contrasted with the work done in D1.2, where empirical evidence was gathered through interviews with CPAs in the case study areas. These interviews highlighted the current practices of different CPAs in the case study areas, which demonstrated the current use of top-down intiatives and communication strategies. In Chapter 3, the gaps are discussed in depth. The gaps were discovered through a thorough analysis of the information provided in both D1.1 and D1.2, with the addition of data on the citizen perspective that is provided in D2.2. There are 15 gaps discussed in this report, which were categorized into the following major themes: - Communication - Theory vs practice - Governance - Operations and implementation - Data and technology Communication gaps address the current lack of communication between CPAs and citizens, and highlight the need for two-way communication, including creating better communication channels to facilitate this two-way communication. CPA and community experiences in communication are discussed, showing the current lack of engagement between the two groups

description: School reintegration following hospitalisation has been explored for children and young people (CYP) with medical and mental health needs. No previous research was identified that specifically focused on the experiences of CYP who have returned to school following inpatient care for an eating disorder. A multiple case study design was used to retrospectively explore the experiences of two young people who successfully reintegrated to school following hospital support for an eating disorder. The study compromised of two case studies. The research focused on exploring ‘what went well’ and ‘what could have been even better’ during the school reintegration process. Semi-structured interviews were used in two case studies of a young person who had spent time at inpatient unit for over 6 months for support with anorexia nervosa before reintegrating into sixth form. Views were gathered from four participants in each case study: the young person, their parent, the young person's previous hospital school key teacher and the home school key person (who supported with the reintegration). The interviews were carried out remotely, via Microsoft Teams, due to the coronavirus pandemic. The dataset from each case study was analysed separately using thematic analysis and an overall thematic map was presented for the findings from each case study. Three themes were identified in Case Study One: young person’s strengths, preparation for young person’s return and supportive relationships and environment. Four themes were identified in Case Study Two: young person’s internal motivators and external motivators, preparing for school return, support systems, and sense of school belonging and connectedness. Findings are discussed in relation to previous research that has explored school reintegration following hospital support for mental health difficulties more broadly and psychological theory. Strengths, limitations and implications for schools, families and educational psychologists are highlighted. Recommendations for future research are also discussed.
Characterizing the time variability in magnetized neutrino--cooled accretion disks: signatures of the gamma-ray burst central engine

description: The central engine of Gamma Ray Bursts is hidden from direct probing with photons mainly due to the high densities involved. Inferences on their properties are thus made from their cosmological setting, energetics, low-energy counterparts and variability. If GRBs are powered by hypercritical accretion onto compact objects, on small spatial scales the flow will exhibit fluctuations, which could in principle be reflected in the power output of the central engine and ultimately in the high energy prompt emission. Here we address this issue by characterizing the variability in neutrino cooled accretion flows through local shearing box simulations with magnetic fields, and then convolving them on a global scale with large scale dynamical simulations of accretion disks. The resulting signature is characteristic, and sensitive to the details of the cooling mechanism, providing in principle a discriminant for GRB central engine properties.

description: The evolution of suspension drops sedimenting under gravity in a viscous fluid close to a vertical wall was studied experimentally and numerically with the use of the point-force model, in the Stokes flow regime. The fluid inside and outside the drop was identical. The initial distribution of the suspended solid heavy particles was uniform inside a spherical volume. In the experiments and in the simulations, the suspension drops evolved qualitatively in the same way as in an unbounded fluid. However, it was observed, both experimentally and numerically that, on the average, the destabilization time T and the distance L traveled by the drop until break-up were smaller for a closer distance h of the drop center from the wall, with approximately linear dependence of T and L on D/h, for h larger or comparable to the drop diameter D. Destabilization times and lengths of individual drops with different random configurations of the particles were shown to differ significantly from each other, owing to the chaotic nature of the particle dynamics.

description: This paper reports the values of contributions to the electron g-2 from 300 Feynman diagrams of the gauge-invariant Set III(a) and 450 Feynman diagrams of the gauge-invariant Set III(b). The evaluation is carried out in two versions. Version A is to start from the sixth-order magnetic anomaly M_6 obtained in the previous work. The mass-independent contributions of Set III(a) and Set III(b) are 2.1275 (2) and 3.3271 (6) in units of (alpha/pi)^5, respectively. Version B is based on the recently-developed automatic code generation scheme. This method yields 2.1271 (3) and 3.3271 (8) in units of (alpha/pi)^5, respectively. They are in excellent agreement with the results of the first method within the uncertainties of numerical integration. Combining these results as statistically independent we obtain the best values, 2.1273 (2), and 3.3271 (5) times (alpha/pi)^5, for the mass-independent contributions of the Set III(a) and Set III(b), respectively. We have also evaluated mass-dependent contributions of diagrams containing muon and/or tau-particle loop. Including them the total contribution of Set III(a) is 2.1349 (2) and that of Set III(b) is 3.3299 (5) in units of (alpha/pi)^5. The total contributions to the muon g-2 of various leptonic vacuum-polarization loops of Set III(a) and Set III(b) are 112.418 (32) and 15.407 (5) in units of (alpha/pi)^5, respectively.

description: One of the problems in the development and maintenance of systems with a microservice architecture is the laboriousness of the process of updating application programming interfaces (API) while maintaining backward compatibility and constant system availability. The paper proposes a solution to the problem - a method of automated deployment and management of a group of services by using the capabilities of infrastructure mechanisms such as orchestration and service mesh. The proposed method was implemented in the form of an integration library and a Kubernetes service that manages the deployment and routing processes. The obtained test results show a significant increase in the automation of an API update process.

description: In this paper, we analyzed the clinical data on the volume flow rate and pressures in the abdominal aorta and the iliac arteries. Based on them, the averaged boundary conditions are specified at the inlet and outlet of the vessel bifurcation. For the first time, a study was conducted of the influence of the elasticity of the vessel walls on the flow of blood in an average statistical model of the bifurcation of the abdominal aorta with iliac arteries. In this work, the flow for elastic and rigid walls in the bifurcation of the abdominal aorta with the iliac arteries for the Reynolds number Re = 1600 in a pulsating flow was calculated. The effect of the elasticity of the vessel walls on the flow structure was investigated.
Neuromechanics of neck muscles : implications for whiplash injury
Creators: name: Fice, Jason Bradley
Publisher: name: University of British Columbia
Year: 2019

description: Occupants involved in automobile collisions can adopt various postures preceding impact. Epidemiologic data have shown increased rates of whiplash associated disorders for drivers who have a rotated head posture or braced themselves before impact. In this dissertation we investigated how neck muscle activity and head/neck kinematics of volunteers are influenced by rotated non-neutral head postures and by bracing against the steering-wheel. We also provided important biomechanical and neuromuscular data to improve computational human body models of the neck (HBMs). In experiment one, 9 males performed neck maximum voluntary isometric contractions (MVIC) in 17 three-dimensional directions. We discovered how neck MVICs scale in directions not aligned with the principal axes and discuss how this scaling relationship can be used to validate an HBM’s off-axis strength, an important step before simulating rotated head postures. In experiment two, the biomechanical lines of action of three key neck muscles, as determined via electrical stimulation, were compared to their preferred activation directions, as determined via muscle activity during 15% MVICs in 26 3D directions (8M volunteers). We showed that neck muscles’ biomechanical lines of action are not an accurate predictor of their function, a finding which will help guide the development of realistic neck muscle controllers in HBMs. In experiment three, we quantified the non-neutral head postures that 20(14M, 6F) drivers adopted while driving on public roads. These data were then used in experiment four, where 12(5F, 7M) volunteers were exposed to low-speed rear impacts on a perturbation sled while in a neutral posture or four common non-neutral postures. In the final experiment, 11(3F, 8M) volunteers were exposed to low-speed frontal and rear impacts with their hands on the steering-wheel while either relaxed or braced by pushing with their arms. We found that non-neutral postures and bracing increased pre-impact muscle activity, but generally did not alter peak muscle activity during impact. Further, sagittal plane kinematic changes suggest a stiffer neck in both non-neutral postures and bracing, but non-neutral postures resulted in motions beyond the sagittal plane. The results of these experiments will help inform injury prevention methods, improve HBMs, and ultimately lead to safer automobiles.
