A thermodynamically consistent stress-rate type model of one-dimensional strain-limiting viscoelasticity

description: We introduce a one-dimensional stress-rate type nonlinear viscoelastic model for solids that obey the assumptions of the strain-limiting theory. Unlike the classical viscoelasticity theory, the critical hypothesis in the present strain-limiting theory is that the linearized strain depends nonlinearly on the stress and the stress rate. We show the thermodynamic consistency of the model using the complementary free energy, or equivalently, the Gibbs free energy. This allows us to take the stress and the stress rate as primitive variables instead of kinematical quantities such as deformation or strain. We also show that the non-dissipative part of the materials in consideration have a stored energy. We compare the new stress-rate type model with the strain-rate type viscoelastic model due to Rajagopal from the points of view of energy decay, the nonlinear differential equations of motion and Fourier analysis of the corresponding linear models.
Development and sharing of ADME/Tox and drug discovery machine learning model

Year: 2015

description: On the order of hundreds of ADME/Tox models have been described in the literature in the last decade which are more often than not inaccessible to anyone but the authors. Public accessibility is also an issue with computational models for bioactivity. A major challenge limiting drug discovery still remains the ability to share such models. We now describe the creation of a reference implementation of a Bayesian model-building software module, which we have released as an open source component that is now included in the Chemistry Development Toolkit (CDK) project, as well as implemented in the CDD Vault and in several mobile apps. We use this implementation to build 18 Bayesian models for ADME/Tox, in vitro and in vivo bioactivity and other physicochemical properties. We show that these models possess cross validation ROC values comparable to those generated previously in prior publications using alternative tools. We have now described how implementation of Bayesian models with FCFP6 descriptors generated in the CDD vault enables the rapid production of robust machine learning models from public data, or the user’s own datasets. The current study sets the stage for generating models in proprietary software such as CDD and exporting these models in a format that could be run in open source software using CDK components. This work also demonstrates that we can enable biocomputation across distributed private or public datasets to enhance drug discovery.

description: No abstracts are to be cited without prior reference to the author. The circulation of Icelandic waters is simulated by the three-dimensional ocean model CODE. The high resolution simulation reveals several new insights into the regional oceanography. Thus, the northward transport of Atlantic Water over the Icelandic shelf, from the Irminger Sea and the Iceland Basin into the Nordic Seas, is simulated as a symmetrical system of two currents, with the established North Icelandic Irminger Current (NIIC) over the north-western and northern shelf, and a hitherto unnamed current over the southern and south-eastern shelf, denoted here as South Icelandic Current (SIC). Both currents are driven by barotropic pressure gradients induced by a sea level slope across the Greenland-Scotland Ridge. Being an upstream precursor of the Faroe Current (FC) the SIC is simulated to be an energetic flow with a mean volume flux of around 2 Sv south-east of Iceland which clearly differs from the wider, sluggish flow of the North Atlantic Drift east of it. With an additional numerical experiment the NIIC/SIC structure is reproduced by an idealised model setup which illuminates its basic dynamics.

description: We present analytic solutions to the Teukolsky equation for massless perturbations of any spin in the 4-dimensional de Sitter background. The angular part of the equation fixes the separation constant to a discrete set and its solution is given by hypergeometric polynomials. For the radial part, we derive analytic power series solution which is regular at the poles and determine a transcendental function whose zeros give the characteristic values of the wave frequency. We study the existence of explicit polynomial solutions to the radial equation and obtain two classes of singular closed-form solutions, one with discrete wave frequencies and the other with continuous frequency spectra.

Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author. Polar lows are intense small scale storms at high latitudes. They are projected to decline in response to anthropogenic climate change, due to an increase in atmospheric stability in this region. Here we show that this increase in stability is controlled by the weakening of the Atlantic Meridional Overturning Circulation (AMOC) in the global climate models. Combined with other recent findings of the influence of Polar Lows on oceanic deep convection, this result raises the possibility of a positive feedback on the strength of the AMOC involving processes not resolved in current coupled climate models.

Roll: a robotic on-board localization system using landmarks
Creators: name: Brewster, Jeffery Charles
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents the design of a system for robot localization named ROLL. The ROLL system was designed to be used in a dynamic real-time robot testbed. The system could provide location information to experimental robot control architectures. There are many existing localization systems for robots using many different techniques and sensors. All of these localization systems either require custom computer hardware or are much too slow or require the robot to stop for a certain period of time for the localization system to produce output. The system in this thesis allows localization without having to have the robot stop, and without the need for expensive custom hardware. The ROLL system uses a camera mounted on the robot facing forward to detect special landmarks placed in the environment. From the shape of the landmarks in the camera image, the position of the camera relative to the robot can be calculated. This position can be transformed into absolute frame coordinates using the known absolute frame position of the landmark. To test the ROLL system, it was implemented in the ACE programming environment on a stand-alone workstation. This implementation was fed sequences of stored images that included a visible landmark to simulate a real robot trajectory. The system was also implemented on a Texas Instruments TMS320C40 DSP board to prove that the algorithm could be run at acceptable real time speeds. The system was able to detect the landmark in all of the images in two series of 11 images each, except for one. The position of the camera was calculated to within 4.2cm of the known position for each image. The TMS320C40 implementation was able to provide location information at an average of approximately 8Hz.

description: Hawking radiation of black ring solutions to 5-dimensional Einstein-Maxwell-dilaton gravity theory is analyzed by use of the Parikh-Wilczek tunnelling method. To get the correct tunnelling amplitude and emission rate, we adopted and developed the Angheben-Nadalini-Vanzo-Zerbini covariant approach to cover the effects of rotation and electronic discharge all at once, and the effect of back reaction is also taken into account. This constitute a unified approach to the tunnelling problem. Provided the first law of thermodynamics for black rings holds, the emission rate is proportional to the exponential of the change of Bekenstein-Hawking entropy. Explicit calculation for black ring temperatures agree exactly with the results obtained via the classical surface gravity method and the quasilocal formalism.

description: No abstracts are to be cited without prior reference to the author. The Iceland Sea is an important part of the North Atlantic climate system, as it is known for water mass formation due to surface cooling. The Iceland Sea receives fresh and cold Arctic waters branching off from the East Greenland Current. A considerable amount of this freshwater flows to the south-east with the East Icelandic Current (EIC). In this study, the freshwater transport of the EIC across the Langanes Northeast section is estimated by a combination of data from a recent current meter mooring close to the Iceland shelf edge, repeated hydrographic surveys, and satellite altimetry. From these data, full-depth absolute geostrophic velocities, and temperature / salinity properties of the EIC are available four times per year, allowing freshwater transport estimates over the entire width of the EIC. The time series covers the period from 1992 to 2012, allowing to assess interannual variability and relation to variations in large-scale atmospheric forcing.

Relations between concurrent hard X-ray sources in solar flares

description: Context: Solar flares release a large fraction of their energy into non-thermal electrons, but it is not clear where and how. Bremsstrahlung X-rays are observed from the corona and chromosphere. Aims: We aim to characterize the acceleration process by the coronal source and its leakage toward the footpoints in the chromosphere. The relations between the sources reflect the geometry and constrict the configuration of the flare. Methods: We studied solar flares of GOES class larger than M1 with three or more hard X-ray sources observed simultaneously in the course of the flare. The events were observed with the X-ray satellite RHESSI from February 2002 until July 2005. We used imaging spectroscopy methods to determine the spectral evolution of each source in each event. The images of all of the five events show two sources visible only at high energies (footpoints) and one source only visible at low energies (coronal or looptop source, in two cases situated over the limb). Results: We find soft-hard-soft behavior in both, coronal source and footpoints. The coronal source is nearly always softer than the footpoints. The footpoint spectra differ significantly only in one event out of five. Conclusions: The observations are consistent with acceleration in the coronal source and an intricate connection between the corona and chromosphere.

Visualising variants on structure in Jalview

Publisher: name: F1000 Research Limited
Year: 2019

description: Jalview is a free, open source Java workbench for working with sequence alignments and structures, available from http://www.jalview.org. The latest release of Jalview (2.11, July 2019) adds the ability to load genomic variant data from VCF (Variant Call Format) files. This poster describes new features in Jalview for interpretation and visualisation of the rich data from VCF, by colouring linked coding and protein sequences and protein structures.

Jalview reads indexed VCF files using the samtools htsjdk Java library. Variants are added as feature annotation to gene, transcript or coding sequences. Ensembl services are used to lift over genomic coordinates if VCF and sequence use different genome reference assemblies. Variants on reverse strand genes are converted to their reverse complement form. If the VCF is VEP-annotated by Ensembl's Variant Effect Predictor, then transcript-specific consequences are assigned to the respective transcript and coding sequences.

Jalview 2.11 adds the ability to colour and filter sequence annotation by associated data ('attributes'). This allows sophisticated visualisation based on data of interest, such as:
- only show sequence_variant features where PolyPhen predicts damaging or SIFTS predicts deleterious
- graduate missense_variant colour by Allele Count (AC) above zero, darkest colour for lowest count
- only show stop_gained variants
- restrict to a chosen range of allele frequencies in a selected subpopulation (e.g. AF_AFR)
Favourite colour and filter configurations can be saved and reapplied, and all settings may be saved in a Jalview project (session) file.

Jalview 2.11.1 (next release) optionally renders coding sequence annotation as 'virtual features' on protein sequences and structure. This allows all of the flexibility of filtering on the coding sequence to apply through to protein and structural context. Alternative colourings can be rapidly explored to investigate regions of interest on structure. Variant data can be overlaid on selected protein annotation (such as binding sites) to explore potential impact on protein function. Protein variants are computed 'on the fly' from the standard codon and any alleles for each amino acid, and shown in tooltips on protein sequence and Jmol structure viewer. Full details of an individual variant can be displayed in a table on request.

Protein annotation may conversely be overlaid on coding data sequences, for example to show how functional domains relate to exon boundaries.

The poster shows six examples of visualisations exploiting these capabilities, using variant data from the gnomAD exome dataset.

description: We present results for light meson masses and pseudoscalar decay constants from the first of a series of lattice calculations with 2+1 dynamical flavors of domain wall fermions and the Iwasaki gauge action. The work reported here was done at a fixed lattice spacing of about 0.12 fm on a 16^3\times32 lattice, which amounts to a spatial volume of (2 fm)^3 in physical units. The number of sites in the fifth dimension is 16, which gives m_{res} = 0.00308(4) in these simulations. Three values of input light sea quark masses, m_l^{sea} \approx 0.85 m_s, 0.59 m_s and 0.33 m_s were used to allow for extrapolations to the physical light quark limit, whilst the heavier sea quark mass was fixed to approximately the physical strange quark mass m_s. The exact rational hybrid Monte Carlo algorithm was used to evaluate the fractional powers of the fermion determinants in the ensemble generation. We have found that f_π= 127(4) MeV, f_K = 157(5) MeV and f_K/f_π= 1.24(2), where the errors are statistical only, which are in good agreement with the experimental values.

description: Automatic text summarization has been widely studied as an important task in natural language processing. Traditionally, various feature engineering and machine learning based systems have been proposed for extractive as well as abstractive text summarization. Recently, deep learning based, specifically Transformer-based systems have been immensely popular. Summarization is a cognitively challenging task - extracting summary worthy sentences is laborious, and expressing semantics in brief when doing abstractive summarization is complicated. In this paper, we specifically look at the problem of summarizing scientific research papers from multiple domains. We differentiate between two types of summaries, namely, (a) LaySumm: A very short summary that captures the essence of the research paper in layman terms restricting overtly specific technical jargon and (b) LongSumm: A much longer detailed summary aimed at providing specific insights into various ideas touched upon in the paper. While leveraging latest Transformer-based models, our systems are simple, intuitive and based on how specific paper sections contribute to human summaries of the two types described above. Evaluations against gold standard summaries using ROUGE metrics prove the effectiveness of our approach. On blind test corpora, our system ranks first and third for the LongSumm and LaySumm tasks respectively.

description: Αυτή η διατριβή έχει ως σκοπό τη σχεδίαση ενός συστήματος μετάδοσης πληροφορίας με χρήση μη αυτόνομων χαοτικών ταλαντωτών για υλοποίηση σε επαναπροσδιορίσιμο υλικό και συγκεκριμένα το SPARTAN3E FPGA της Xilinx. Οι ψηφιακοί ταλαντωτές προέρχονται από ψηφιοποίηση μη αυτόνομων αναλογικών χαοτικών ταλαντωτών. Πιο συγκεκριμένα, στο περιβάλλον εξομοίωσης του Cadence, ερευνώνται διάφορες μέθοδοι διαμόρφωσης του σήματος διέγερσης ώστε να αποσταλεί ολοκληρωμένα πληροφορία. Ύστερα, με χρήση αριθμητικής ανάλυσης, ανάλυσης ευστάθειας και εξομοίωσης, ο αναλογικός ταλαντωτής μετατρέπεται σε ψηφιακό και μέσω περιγραφής σε VHDL, υλοποιείται στο FPGA. Επειδή το νέο κύκλωμα, λόγω της ψηφιοποίησης, εμφανίζει διαφορετική χαοτική συμπεριφορά, βρίσκεται ο μέγιστος εκθέτης Lyapunov για ένα εύρος διαφορετικών συχνοτήτων διέγερσης. Τέλος, σχεδιάζεται το τελικό ψηφιακό σύστημα, χρησιμοποιώντας τον ιδανικό χαοτικό συγχρονισμό μεταξύ τους, την PWM διαμόρφωση του σήματος διέγερσης, ενώ η σωστή λειτουργία του επιβεβαιώνεται και από το υλικό αλλά και μέσω εξομοίωσης.
description: This dissertation intends to the realization of transmission of information, by the use of non autonomous digital chaotic oscillators; the system was implemented by reconfigurable hardware in particular the SPARTAN3e FPGA series, manufactured by Xilinx. The digital oscillators are realized by digitizing following the original guidelines of analog non autonomous chaotic oscillators previously by the group. Additionally the Cadence simulating environment was utilized to investigate various methods of modulating an excitation signal, used to implement a complete transmission of information, in a unified fashion. Numerical analysis, stability analysis and simulation was used to convert the analog oscillator to a digital one, described by the associated VHDL and monitored on the appropriate FPGA hardware. Because the new circuit exhibits different chaotic behavior, we found the maximal Lyapunov exponent for broad range of different excitation frequencies. Finally, the new digital system was designed, by exploiting the identical chaotic synchronization between of the proposed PWM digitally chaotic modulated response. Results from hardware and simulations confirms the system’s overall proper functionality.

description: No abstracts are to be cited without prior reference to the author. The Iceland Sea is split into two separate basins by the Kolbeinsey Ridge. It is separated in two parts by the Spar Fracture Zone at 69°N, with a sill depth of roughly 1400 m, that provides a corridor between the two basins. The depth at the crest of the ridge is less than 1000 m over most of its extent. In the area around the Spar Fracture Zone many currents are interacting, such as the East Greenland Current, the North Icelandic Irminger Current, the North Icelandic Jet and the East Icelandic Current as well as the cyclonic Gyre circulation over the Iceland Plateau. In recent years, several studies, including hydrographic surveys and current meter moorings, have been carried out, that have shed some light on the circulation in this area. Altimetry data are also used to investigate the surface currents in the area. New features of the circulation have been revealed that have improved our understanding as well as giving rise to new questions regarding the circulation.

description: In this paper, we present the identification of five previously unknown giant radio galaxies (GRGs) using Data Release 1 of the Radio Galaxy Zoo citizen science project and a selection method appropriate to the training and validation of deep learning algorithms for new radio surveys. We associate one of these new GRGs with the brightest cluster galaxy (BCG) in the galaxy cluster GMBCG J251.67741+36.45295 and use literature data to identify a further 13 previously known GRGs as BCG candidates, increasing the number of known BCG GRGs by >60%. By examining local galaxy number densities for the number of all known BCG GRGs, we suggest that the existence of this growing number implies that GRGs are able to reside in the centers of rich ($\sim 10^{14}$ M$_{\odot}$) galaxy clusters and challenges the hypothesis that GRGs grow to such sizes only in locally under-dense environments.
Likelihood Methods for Cluster Dark Energy Surveys

description: Galaxy cluster counts at high redshift, binned into spatial pixels and binned into ranges in an observable proxy for mass, contain a wealth of information on both the dark energy equation of state and the mass selection function required to extract it. The likelihood of the number counts follows a Poisson distribution whose mean fluctuates with the large-scale structure of the universe. We develop a joint likelihood method that accounts for these distributions. Maximization of the likelihood over a theoretical model that includes both the cosmology and the observable-mass relations allows for a joint extraction of dark energy and cluster structural parameters.

description: GreenLab Model is a functional-structural plant growth model that combines both organogenesis (at each cycle, new organs are created with respect to genetic rules) and photosynthesis (organs are filled with the biomass produced by the leaves photosynthesis). Our new developments of the model concern the retroaction of photosynthesis on organogenesis. We present here the first step towards the total representation of this retroaction, where the influence of available biomass on the number of metamers in new growth units us modelled. The theory is introduced and applied to a Corner model tree. Different interesting behaviours are pointed out.

Mutually Unbiased Bases for Continuous Variables

description: The concept of mutually unbiased bases is studied for N pairs of continuous variables. To find mutually unbiased bases reduces, for specific states related to the Heisenberg-Weyl group, to a problem of symplectic geometry. Given a single pair of continuous variables, three mutually unbiased bases are identified while five such bases are exhibited for two pairs of continuous variables. For N = 2, the golden ratio occurs in the definition of these mutually unbiased bases suggesting the relevance of number theory not only in the finite-dimensional setting.

description: No abstracts are to be cited without prior reference to the author. The Barents Sea throughflow accounts for approximately half of the Atlantic Water advection to the Arctic Ocean. Within the Barents Sea, the Atlantic Water undergoes considerable modifications before entering the Arctic Ocean through the St. Anna Trough. While the inflow area in the south-western Barents Sea is regularly monitored, oceanographic data from the outflow area to the northeast are scarce. Here, we use CTD (Conductivity, Temperature, and Depth) data from August/September 2008 to describe in detail the water masses present in the downstream area of the Barents Sea, their spatial distribution and transformations. We find that the Barents Sea Branch Water consists of both locally formed Cold Deep Water and modified Atlantic Water. While the Cold Deep Water represents a temperature and salinity minimum, the Atlantic component is identified by both temperature and salinity increasing with depth. As opposed to earlier reports, we find that the densest part of the Barents Sea Branch Water is more saline than the Fram Strait Branch Water observed within the St. Anna Trough. Despite the recent warming of the Barents Sea, locally formed bottom water observed in the St. Anna Trough matches the potential density at 2000 meter depth in the Arctic Ocean.

description: We exhibit a lower-triangular matrix of polynomials $T(a,c,d,e,f,g)$ in six indeterminates that appears empirically to be coefficientwise totally positive, and which includes as a special case the Eulerian triangle. We prove the coefficientwise total positivity of $T(a,c,0,e,0,0)$, which includes the reversed Stirling subset triangle.

Integrating simulation and animation software systems through a generic computational engine
Creators: name: Walker, Robert James
Publisher: name: University of British Columbia
Year: 2009

description: There continue to be a proliferation of simulation/animation software packages. These packages typically are not designed to communicate in a general fashion with others, or if they do, often require tight restrictions on the conceptual designs of their partners typically in terms of temporal management. Attempting to combine and coordinate such disparate packages leads to the requirement of a system for the manipulation, configuration, and synchronization of communication between them. The form of such a communication system is naturally described in terms of a graph; thus, the need for a means to utilize some sort of graph or network as a computational engine arises. A particular formulation of coloured Petri nets (CPNs) is seen to be an effective vehicle to this end; in addition, a system built out of CPNs has the ability to be directly analyzed, since that is what CPNs were originally devised for. This work demonstrates an efficient implementation method which also leads to additional, desirable features such as permitting a hierarchical construction language.
Entanglement Purification of Any Stabilizer State

description: We present a method for multipartite entanglement purification of any stabilizer state shared by several parties. In our protocol each party measures the stabilizer operators of a quantum error-correcting code on his or her qubits. The parties exchange their measurement results, detect or correct errors, and decode the desired purified state. We give sufficient conditions on the stabilizer codes that may be used in this procedure and find that Steane's seven-qubit code is the smallest error-correcting code sufficient to purify any stabilizer state. An error-detecting code that encodes two qubits in six can also be used to purify any stabilizer state. We further specify which classes of stabilizer codes can purify which classes of stabilizer states.

description: No abstracts are to be cited without prior reference to the author. A comparison of the mean conditions and variability in the climate and physical oceanographic characteristics between the Labrador Sea and surrounding shelves and the Norwegian and Barents seas is presented. Several climate and oceanographic variables, including air temperatures, eastward winds, heat fluxes, and the range of seasonal sea surface temperature range show a general latitudinal dependence within each of the two regions but with regional varying rates of change with latitude. The previously reported out-of-phase relationships on interannual to decadal time scales of air and sea temperatures and sea-ice conditions between the Labrador Sea and the Norwegian and Barents seas regions from the 1950s until the mid-1990s was found. This is owing to their opposite response to the variability in the North Atlantic Oscillation (NAO). However, from the mid-1990s, air and sea temperatures in both regions generally have been in phase, showing strong warming and reduced ice coverage. The cause of this change is related to changes in the spatial structure of the atmospheric pressure patterns, resulting in a general reduction in the importance of NAO forcing over the North Atlantic.
