A web service based disaster response interface for the DR NEP platform
Creators: name: Wang, Tiange
Publisher: name: University of British Columbia
Year: 2012

description: The Infrastructure Interdependencies Simulation (I2Sim) team led by Dr. José R. Martí at the University of British Columbia has been researching the hidden interdependencies between complex infrastructures for several years [1]. The I2Sim platform was developed on the foundation of Matlab Simulink and has been significantly improved by researchers and engineers since the first version of the toolbox created in 2007 [2]. The current version of the I2Sim toolbox has versatile capabilities on many applications such as disaster response, resource optimization, financial management, etc. For disaster response application, in particular, the I2Sim team has formed a group of engineers in cooperation with the University of Western Ontario and the University of New Brunswick to develop the Disaster Response Network Enabled Platform (DR NEP). DR NEP is a distributed platform that communicates through an Enterprise Service Bus (ESB)utilizing the state-of-the-art Lightpath services provided by CANARIE. With advanced computing power and high speed network connections, DR NEP is able to integrate I2Sim with other simulators and services, which are physically located all over Canada, to perform real time simulations and provide decision support for emergency responders. To further enhance user experience and improve the user interface for emergency responders, Web services were used in the project to create a web-based platform to display the simulation results on web pages and GIS systems, such as Google Earth. This platform enables responders to update and exchange information from standard web browsers and Google Earth. Simulation experts can use the website to control simulation and view simulation results and feedback from the website. A test case which involves the 2011 Tohoku earthquake incident in Japan is included in this report to demonstrate the simplicity of the user interface and the contribution of the web service to DR NEP. In addition, "what-if" scenarios were conducted on the model to explore better emergency responding strategies. The results from the simulation were studied and analyzed in detail. DR NEP is a fully functioning platform with complete components. With sufficient information provided by emergency responders or local resource management facilities, a complete model can be constructed for simulation and study. The next phase of the development would be model automatic creation, ergonomic user interface design, improvement on role-based access and model validation methodology development. Recommendations to those problems are included accordingly. As a member of the DR NEP team, I have been involved in most of the phases of the platform development. My main contribution to the team includes designing part of the table structures in database schema, implementing the web services for data visualization (Google Earth and the associated web services) and constructing the Japan Sendai City model.

description: Casimir-Polder interactions between an atom and a macroscopic body are typically regarded as due to the exchange of virtual photons. This is strictly true only at zero temperature. At finite temperature, real-photon exchange can provide a significant contribution to the overall dispersion interaction. Here we describe a new resonant two-photon process between an atom and a planar interface. We derive a second order effective Hamiltonian to explain how atoms can couple resonantly to the surface polariton modes of the dielectric medium. This leads to second-order energy exchanges which we compare with the standard nonresonant Casimir-Polder energy.

description: No abstracts are to be cited without prior reference to the author.Cod cannibalism in the Eastern Baltic Sea was most intensive in 1978–1984, a period with high juvenile abundance and large adult stock size. Approximately 60% of the 0-group and 30% of the 1group cod were consumed by conspecifics. Subsequently, cod recruitment and adult stock decreased, whereas sprat, the main fish prey for cod, became significantly more abundant. Predation rates on 0-group and 1-group cod decreased to 23% and 9%. Since 2003 cod stock size has increased again, and predation on the 0-group has also increased. Predation on the 1-group, however, has not increased as yet. Analysing trawl survey data and cod stomach content data in connection with a multispecies model, we show that the stagnant predation on age group 1 is a product of size structure at increasing adult cod biomass during recovery, and spatial overlap between small and large cod. We also address whether the changes in spatial overlap are a result of density-dependent habitat selection, environmental forcing, or a combination of both.

description: No abstracts are to be cited without prior reference to the author.Since 2002 the recruitment of North Sea herring has been below average and the signal can be easily seen in surveys of metamorphic larvae. From the 1970s onwards the recruitment strength of North Sea herring has been determined somewhere between the hatch and metamorphosis of the larvae. Larval abundance (1972–2008) was coupled to a spatial hydrodynamic model to investigate whether the mean daily mortality rates have increased since 2002. Tracked cohort mortality rates (horizontal life table approach) were compared with ”snapshot” estimates (vertical life table approach, i.e. decline across ages at one point in time). Distinct trends in the mortality rates were evident using dynamic factor analysis: the Downs component (southern) exhibited a constant rise in mortality, whereas the other three components (northern) demonstrated a shared distinct increase after 2002. The use of this long time-series of field surveys has provided valuable information on the trends in mortality rates and highlights that the signal of poor recruitment from 2002 onwards coincides with an increase in mortality in larvae younger than 30 days post-hatch (<16 mm). This suggests that year-class strength is determined very early in the development of North Sea herring perhaps associated with a critical period in the first 30 days.

description: A complete sample of bright Swift Gamma-ray Bursts (GRBs) has been recently selected by Salvaterra et al. (2011). The sample has a high level of completeness in redshift (91%). We derive here the intrinsic absorbing X-ray column densities of these GRBs making use of the Swift X-ray Telescope data. This distribution has a mean value of log(NH/cm-2)=21.7+-0.5. This value is consistent with the distribution of the column densities derived from the total sample of GRBs with redshift. We find a mild increase of the intrinsic column density with redshift. This can be interpreted as due to the contribution of intervening systems along the line of sight. Making use of the spectral index connecting optical and X-ray fluxes at 11 hr (beta_OX), we investigate the relation of the intrinsic column density and the GRB `darkness'. We find that there is a very tight correlation between dark GRBs and high X-ray column densities. This clearly indicates that the dark GRBs are formed in a metal-rich environment where dust must be present.

title: Amyloid Precursor Protein: An adhesion protein and a novel talin binder
Creators: name: Rice, Matthew Robert Edward
Publisher: name: University of Kent
Year: 2023

description: Amyloid precursor protein (APP), the amyloid plaque forming protein, hypothesised to be involved in the development of Alzheimer's disease (AD) is an adhesion protein which localises to focal adhesions. The amyloid cascade hypothesis has resulted in the role of APP in adhesions being largely overlooked and understudied. This research provides the first experimental evidence of a novel protein interaction between APP and talin, another adhesion protein, and highlights a novel role of APP within focal adhesions. This protein interaction, shown here for the first time, highlights a new set of mechanical linkages available to cells within adhesions. Several biochemical and biophysical techniques were employed to investigate and characterise this interaction including Fluorescence Polarisation, Nuclear Magnetic Resonance and Microscale Thermophoresis. These techniques supported a direct interaction between the F2F3 domain of talin and the intracellular domain of APP. We were also able to show that this interaction is stronger in the presence of a lipid bilayer which mimics a cellular membrane. Both talin and APP are involved in several biological functions and so their ability to interact suggests an abundance of new nteractions between the binding partners of each protein when undertaking different roles. Importantly within neuroscience, this interaction may be crucial in shedding light on discrepancies within the amyloid cascade hypothesis and may well provide the basis for a more comprehensive explanation of AD onset.

description: Although there are a wealth of column density tracers for both the molecular and diffuse interstellar medium, there are very few observational studies investigating the relationship between the density variance ($σ^2$) and the sonic Mach number (${\cal M}_s$). This is in part due to the fact that the $σ^2$-${\cal M}_s$ relationship is derived, via MHD simulations, for the 3D density variance only, which is not a direct observable. We investigate the utility of a 2D column density $σ_{Σ/Σ_0}^2$-${\cal M}_s$ relationship using solenoidally driven isothermal MHD simulations and find that the best fit follows closely the form of the 3D density $σ_{ρ/ρ_0}^2$-${\cal M}_s$ trend but includes a scaling parameter $A$ such that: $σ_{ln(Σ/Σ_0)}^2=A\times ln(1+b^2{\cal M}_s^2)$, where $A=0.11$ and $b=1/3$. This relation is consistent with the observational data reported for the Taurus and IC 5146 molecular clouds with $b=0.5$ and $A=0.16$ and $b=0.5$ and $A=0.12$, respectively. These results open up the possibility of using the 2D column density values of $σ^2$ for investigations of the relation between the sonic Mach number and the PDF variance in addition to existing PDF sonic Mach number relations.

Bayesian phylogenetic inference via Monte Carlo methods
Creators: name: Wang, Liangliang
Publisher: name: University of British Columbia
Year: 2013

description: A main task in evolutionary biology is phylogenetic tree reconstruction, which determines the ancestral relationships among di erent species based on observed molecular sequences, e.g. DNA data. When a stochastic model, typically continuous time Markov chain (CTMC), is used to describe the evolution, the phylogenetic inference depends on unknown evolutionary parameters (hyper-parameters) in the stochastic model. Bayesian inference provides a general framework for phylogenetic analysis, able to implement complex models of sequence evolution and to provide a coherent treatment of uncertainty for the groups on the tree. The conventional computational methods in Bayesian phylogenetics based on Markov chain Monte Carlo (MCMC) cannot e ciently explore the huge tree space, growing super exponentially with the number of molecular sequences, due to di culties of proposing tree topologies. sequential Monte Carlo (SMC) is an alternative to approximate posterior distributions. However, it is non-trivial to directly apply SMC to phylogenetic posterior tree inference because of its combinatorial intricacies. We propose the combinatorial sequential Monte Carlo (CSMC) method to generalize applications of SMC to non-clock tree inference based on the existence of a flexible partially ordered set (poset) structure, and we present it in a level of generality directly applicable to many other combinatorial spaces. We show that the proposed CSMC algorithm is consistent and fast in simulations. We also investigate two ways of combining SMC and MCMC to jointly estimate the phylogenetic trees and evolutionary parameters, particle Markov chain Monte Carlo (PMCMC) algorithms with CSMC at each iteration and an SMC sampler with MCMC moves. Further, we present a novel way to estimate the transition probabilities for a general CTMC, which can be used to solve the computing bottleneck in a general evolutionary model, string-valued continuous time Markov Chain (SCTMC), that can incorporate a wide range of molecular mechanisms.

description: The Hamiltonian structures of the incompressible ideal fluid, including entropy advection, and magnetohydrodynamics are investigated by making use of Dirac's theory of constrained Hamiltonian systems. A Dirac bracket for these systems is constructed by assuming a primary constraint of constant density. The resulting bracket is seen to naturally project onto solenoidal velocity fields.
Astrophysical foregrounds and primordial tensor-to-scalar ratio constraints from CMB B-mode polarization observations

Publisher: name: arXiv

description: We study the effects of astrophysical foregrounds on the ability of CMB B-mode polarization experiments to constrain the primordial tensor-to-scalar ratio, r. To clean the foreground contributions we use parametric, maximum likelihood component separation technique, and consider experimental setups optimized to render a minimal level of the foreground residuals in the recovered CMB map. We consider nearly full-sky observations, include two diffuse foreground components, dust and synchrotron, and study cases with and without calibration errors, spatial variability of the foreground properties, and partial or complete B-mode lensing signal removal. In all these cases we find that in the limit of very low noise level and in the absence of the intrumental or modeling systematic effects, the foreground residuals do not lead to a limit on the lowest detectable value of r. But the need to control the foreground residuals will play a major role in determining the minimal noise levels necessary to permit a robust detection of r < 0.1 and therefore in optimizing and forecasting the performance of the future missions. For current and proposed experiments noise levels, the foreground residuals are found non-negligible and potentially can affect our ability to set constraints on r. We also show how the constraints can be significantly improved on by restricting the post component separation processing to a smaller sky area. This procedure applied to a case of a COrE-like satellite mission is shown to result potentially in over an order of magnitude improvement in the detectable value of r. With sufficient knowledge of the experimental bandpasses as well as foreground component scaling laws, our conclusions are found to be independent on the assumed overall normalization of the foregrounds and only quantitatively depend on specific parametrizations assumed for the foreground components.

description: The task of multimodal cancer detection is to determine the locations and categories of lesions by using different imaging techniques, which is one of the key research methods for cancer diagnosis. Recently, deep learning-based object detection has made significant developments due to its strength in semantic feature extraction and nonlinear function fitting. However, multimodal cancer detection remains challenging due to morphological differences in lesions, interpatient variability, difficulty in annotation, and imaging artifacts. In this survey, we mainly investigate over 150 papers in recent years with respect to multimodal cancer detection using deep learning, with a focus on datasets and solutions to various challenges such as data annotation, variance between classes, small-scale lesions, and occlusion. We also provide an overview of the advantages and drawbacks of each approach. Finally, we discuss the current scope of work and provide directions for the future development of multimodal cancer detection.

description: No abstracts are to be cited without prior reference to the author.The overlap between predator and prey is known as a sensitive parameter in multispecies assessment models for fish, and its parameterization is notoriously difficult. Overlap indices were derived from the North Sea IBTS survey and used to parameterize the North Sea Stochastic Multi Species Model (SMS). The impact of different levels of detail in the overlap implementation (constant or year and quarter specific) on the historic (1991–2007) and predicted trophic interactions as well as the development of predator and prey stocks was investigated. The focus was on a general comparison between single-species and multispecies forecasts and the sensitivity of the predicted North Sea cod recovery towards different overlap implementations. The spatiotemporal overlap between cod and its predators was found to increase with increasing temperature, indicating that foodweb processes will potentially reduce the recovery potential of cod, especially in warm periods. Multispecies scenarios were highly influenced by assumptions on future spatial overlap and predicted a considerably lower recovery potential than single-species predictions. In addition, a negative impact of a North Sea cod recovery on its prey stocks was found in the multispecies forecasts. The consequences of these findings for management concepts were discussed.

Extended Josephson Relation and Abrikosov lattice deformation

description: From the point of view of time-dependent Ginzburg Landau (TDGL) theory, a Josephson-like relation is derived for an Abrikosov vortex lattice accelerated and deformed by applied fields. Beginning with a review of the Josephson Relation derived from the two ingredients of a lattice-kinematics assumption in TDGL theory and gauge invariance, we extend the construction to accommodate a time-dependent applied magnetic field, a floating-kernel formulation of normal current, and finally lattice deformation due to the electric field and inertial effects of vortex-lattice motion. The resulting Josephson-like relation, which we call an Extended Josephson Relation, applies to a much wider set of experimental conditions than the original Josephson Relation, and is explicitly compatible with the considerations of TDGL theory.

description: No abstracts are to be cited without prior reference to the author.In ordinary catch-at-age models, natural mortality conditions and determines the catchabilities at age obtained in the surveys that tune the assessments. For the same reason, inferring the natural mortality of a fish stock from survey estimates requires some assumption of the survey catchabilities at age. The anchovy fishery in the Bay of Biscay has been closed since 2005 (to date) because of low biomass levels. At the time, since 1989 the population has been directly monitored by two independent surveys—an acoustic survey and an egg (DEPM) survey—which have supplied basic information for the assessment of this stock by ICES. The closure of the fishery supposes a major change in total mortality levels affecting the population compared with the former period of exploitation, allowing estimates of natural and fishing mortalities, assuming that no major changes in M occur between both periods. A seasonal integrated catch-at-age analysis was tuned to the fishery and two series of surveys under the assumption of constant catchabilities across age for the two surveys’ population estimates. An analysis of the period 1987–2009, searching for a single and constant natural mortality-at-age, results in minimum residual SSQ for an M around 0.8. But a better result is obtained when a pattern of increasing natural mortality-atage is allowed, a possibility suggested a long time ago for this type of short-living species.

SU(3) symmetry breaking and CP violation in D -> PP decays

description: Evidence of CP violation in the charm sector has been observed recently by the LHCb and CDF Collaborations. Adopting the topological diagram approach, we study flavor SU(3) symmetry breaking effects in the weak decay tree amplitudes of singly Cabibbo-suppressed $D\to PP$ decays. The symmetry breaking in the color-allowed and color-suppressed amplitudes is estimated with the help of the factorization ansatz, while that in the $W$-exchange amplitude is done by fitting to related branching fraction data. We find that the $W$-exchange amplitudes stay in the second quadrant relative to the color-allowed tree amplitude, albeit there are two possibilities for one type of $W$-exchange amplitude. The weak decay penguin amplitudes, on the other hand, are evaluated within the framework of QCD factorization. Using the input of topological tree amplitudes extracted from the Cabibbo-favored decay modes and the perturbative results for QCD penguin amplitudes, we make predictions for the branching fractions and CP asymmetries of singly Cabibbo-suppressed modes. The predictions of branching fractions are generally improved from those in the SU(3) limit. We conclude that the direct CP asymmetry difference between $D^0 \to K^+ K^-$ and $D^0 \to π^+ π^-$ is about $-(0.139\pm 0.004)%$ and $-(0.151\pm 0.004)%$ for the two solutions of $W$-exchange amplitudes, respectively. We also find that the CP asymmetry of $D^0\to K^0\ov K^0$ dominated by the interference between $W$-exchange amplitudes ranges from $-0.62\times 10^{-3}$ to $-1.82\times 10^{-3}$. We study phenomenological implications of two new physics scenarios for explaining the observed CP asymmetry in the charm sector, one with large penguin amplitudes and the other with a large chromomagnetic dipole operator. We find that the two scenarios can be discriminated by the measurements of CP asymmetries of a set of decay modes.

description: Accurately credit default prediction faces challenges due to imbalanced data and low correlation between features and labels. Existing default prediction studies on the basis of gradient boosting decision trees (GBDT), deep learning techniques, and feature selection strategies can have varying degrees of success depending on the specific task. Motivated by this, we propose Tab-Attention, a novel self-attention-based stacked generalization method for credit default prediction. This approach ensembles the potential proprietary knowledge contributions from multi-view feature spaces, to cope with low feature correlation and imbalance. We organize multi-view feature spaces according to the latent linear or nonlinear strengths between features and labels. Meanwhile, the f1 score assists the model in imbalance training to find the optimal state for identifying minority default samples. Our Tab-Attention achieves superior Recall_1 and f1_1 of default intention recognition than existing GBDT-based models and advanced deep learning by about 32.92% and 16.05% on average, respectively, while maintaining outstanding overall performance and prediction performance for non-default samples. The proposed method could ensemble essential knowledge through the self-attention mechanism, which is of great significance for a more robust future prediction system.

description: No abstracts are to be cited without prior reference to the author.Finite-state continuous-time models provide a framework for simultaneous inference of various population dynamics parameters such as mortality and migration rates. These models are particularly useful for analysing data arising from tagging studies such as tag-recovery experiments because of the ability to simultaneous account for nuisance parameters associated with these data. These nuisance parameters account for aspects such as tag-reporting behaviour, tag shedding, and temporary tag-induced changes in behaviour. It is important to account for these parameters for the scale of estimated fishing and natural mortality to be correct. Migration and mortality rates can also be modelled as functions of environmental covariates. The analytical approach is illustrated with an application to an Atlantic cod tagging experiment in the Northwest Atlantic Ocean. For Atlantic cod we consider models that allow ontogenic changes in migration between three adjacent regions as well as fishing and natural mortality rates that may be regionspecific.

description: In this paper, we study the effects of an interaction between dark matter and dark energy through a two scalar field model with a potential $V(ϕ,χ)=e^{-λϕ}P(ϕ,χ)$, where $P(ϕ,χ)$ is a polynomial. We show that the cosmic expansion dynamics of the Universe is reproduced for a large range of the bare mass of the dark matter field and that there exist solutions with transient accelerated expansion. A modification in the exponential behavior of the potential is studied, with important physical implications, including the possibility of more realistic transient acceleration solutions.

Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Building on work by Andersen and Beyer, Pedersen and co-workers recently developed a numerical model for community size spectra that resolves both species, characterized by maturation body size, and the individual size distributions within species. Empirical values for all model parameters are known. Here, an analytic characterization of static and dynamic model states is presented. The combined equilibrium conditions for (i) population structure, (ii) population size, and (iii) size-spectrum slope imply that predation mortality (M) must generally equal the massspecific individual growth rate (specific physiological mortality = 1), but is lower for the smallest individuals—confirming and explaining simulation results by Pedersen et al. This, in turn, implies an equilibrium condition for (iv) the size-spectrum offset (i.e. absolute biomass density). However, the dependence of specific physiological mortality on biomass density, and hence the density dependence of size-spectrum dynamics, can be weak, and then external effects control community structure. The theory predicts that and how perturbations of the size spectrum (e.g. by fishing) propagate to larger species (at a rate that generally differs from individual growth rates), and the time-scale of recovery to the unperturbed spectrum. Concerns that community perturbations by fishing may cascade to lower trophic levels are not supported by this theory.
Instabilities of Bosonic Spin Currents in Optical Lattices

description: We analyze the dynamical and energetic instabilities of spin currents in a system of two-component bosons in an optical lattice, with a particular focus on the Neel state. We consider both the weakly interacting superfluid and the strongly interacting Mott insulating limits as well as the regime near the superfluid-insulator transition and establish the criteria for the onset of these instabilities. We use Bogoliubov theory to treat the weakly interacting superfluid regime. Near the Mott transition, we calculate the stability phase diagram within a variational Gutzwiller wavefunction approach. In the deep Mott limit we discuss the emergence of the Heisenberg model and calculate the stability diagram within this model. Though the Bogoliubov theory and the Heisenberg model (appropriate for deep superfluid and deep Mott phase respectively) predict no dynamical instabilities, we find, interestingly, between these two limiting cases there is a regime of dynamical instability. This result is relevant for the ongoing experimental efforts to realize a stable Neel-ordered state in multi-component ultracold bosons.
