description: SH$^+$ is a surprisingly widespread molecular ion in diffuse interstellar clouds. There, it plays an important role triggering the sulfur chemistry. In addition, SH$^+$ emission lines have been detected at the UV-illuminated edges of dense molecular clouds, \mbox{so-called} photo-dissociation regions (PDRs), and toward high-mass protostars. An accurate determination of the SH$^+$ abundance and of the physical conditions prevailing in these energetic environments relies on knowing the rate coefficients of inelastic collisions between SH$^+$ molecules and hydrogen atoms, hydrogen molecules, and electrons. In this paper, we derive SH$^+$--H fine and hyperfine-resolved rate coefficients from the recent quantum calculations for the SH$^+$--H collisions, including inelastic, exchange and reactive processes. The method used is based on the infinite order sudden approach. State-to-state rate coefficients between the first 31 fine levels and 61 hyperfine levels of SH$^+$ were obtained for temperatures ranging from 10 to 1000 K. Fine structure-resolved rate coefficients present a strong propensity rule in favour of $Δj = ΔN$ transitions. The $Δj = ΔF$ propensity rule is observed for the hyperfine transitions. {The new rate coefficients will help significantly in the interpretation of SH$^+$ spectra from PDRs and UV-irradiated shocks where the abundance of hydrogen atoms with respect to hydrogen molecules can be significant.

description: Teams are relied upon in extreme and challenging environments in which there are considerable demands and failures can have severe consequences. Despite an increased interest in extreme teams, empirical research remains limited. Moreover, whilst the literature differentiates between extreme and non-extreme teams, it rarely distinguishes between different types of extreme teams. In this thesis, I argue extreme teams can be differentiated into multi-team systems (MTS) and teams in isolated, confined environments (ICE). I draw on contextual challenges present in different types of extreme environments to examine what factors support teamwork in emergency response teams (MTS) and expedition teams (ICE). In doing so, I identify methodological and analytical approaches suitable for researching extreme teams (Chapter II and V). MTS often form quickly in the response to emergencies. This creates challenges in establishing communication channels and managing conflicting objectives across inter-agency partners who may have limited experience working with one another. To address these challenges, I explored how teams communicated and coordinated in crises and if this is influenced by team member familiarity. Data were collected from immersive simulations with commanders in the emergency services and students. Mixed methods analysis showed how team processes changed across time (Chapter III) and how familiarity (Chapter IV) alleviated some of the challenges of working in MTS. In contrast to MTS, teams in ICE co-exist for pro-longed periods in hostile and remote settings. This creates challenges in maintaining team cohesion and balancing the personalities and characteristics of isolated individuals for pro-longed periods. Here, I used a diary methodology to track changes in cohesion over time and explore if fluctuations in cohesion are predicted by day-to-day events and the personality composition of teams (Chapter V). Theoretical implications for the importance of context in shaping team behaviours and practical implications for teams operating in extreme environments are provided.

description: Simultaneous spectral differential imaging is a high contrast technique by which subtraction of simultaneous images reduces noise from atmospheric speckles and optical aberrations. Small non-common wave front errors between channels can seriously degrade its performance. We present a new concept, a multicolor detector assembly (MCDA), which can eliminate this problem. The device consists of an infrared detector and a microlens array onto the flat side of which a checkerboard pattern of narrow-band micro-filters is deposited, each micro-filter coinciding with a microlens. Practical considerations for successful implementation of the technique are mentioned. Numerical simulations predict a noise attenuation of 10^-3 at 0.5" for a 10^5 seconds integration on a mH=5 star of Strehl ratio 0.9 taken with an 8-m telescope. This reaches a contrast of 10^-7 at an angular distance of 0.5" from the center of the star image.

The linearization of affixes : evidence from Nuu-chah-nulth
Creators: name: Wojdak, Rachel
Publisher: name: University of British Columbia
Year: 2009

description: This dissertation addresses the linearization of affixes, and argues for a particular model of the way in which syntax maps to phonology. According to the proposal, syntax is spelled-out to phonology in minimal cycles equivalent to a single application of syntactic Merge (cf. Epstein et al. 1999). I term this proposal the local spell-out hypothesis. The empirical grounds on which this hypothesis is assessed is Nuu-chah-nulth (Nootka), a Southern Wakashan language spoken in British Columbia, Canada. Nuu-chah-nulth has a class of morphologically bound predicates termed affixal predicates which participate in a linearization strategy of suffixation. I claim that affixes in Nuu-chah-nulth are linearized at spell-out with respect to 'hosts' as a consequence of the PF requirement that utterances be sequentially ordered. Spell-out induces in Nuu-chah-nulth a relationship which I label PF Incorporation. The affixal predicate 'incorporates' its host in order to achieve a pronounceable form, that of a linearized affix. An affixal predicate in Nuu-chah-nulth consistently suffixes to a host chosen from its derivational sister, its complement. This suffixation pattern is subject to a string adjacency effect: an affixal predicate incorporates only the leftmost element from its complement, which happens to be contiguous with the affixal predicate. I present the argument that the local spellout hypothesis elegantly captures this dual sensitivity to derivational sisterhood and linear adjacency. Although the spell-out mechanism which induces linearization of affixes is nonsyntactic, syntactic sisterhood conditions linearization opportunities at PF via the composition of local spell-out domains. This dissertation presents a variety of diagnostics for Nuu-chah-nulth clausal structure, with a particular focus on the argument structure of affixal predicates. Amongst affixal predicates which take nominal complements, predicates range from unaccusative to extended unaccusative, transitive to ditransitive. Unergatives, however, are systematically absent from the inventory of affixal predicates in Nuu-chah-nulth. Amongst affixal predicates which take verbal complements, both modal and main predicates are found. A consequence of the analysis is that syntax is 'phonologized' over the course of the derivation, in minimal stages induced by application of Merge. Linearization is thus established in increments. This analysis has implications for the grammatical locus of head movement operations: head movement is not strictly phonological (contra Chomsky 1995, 2001).

description: The Accountability Principle of the GDPR requires that an organisation can demonstrate compliance with the regulations. A survey of GDPR compliance software solutions shows significant gaps in their ability to demonstrate compliance. In contrast, RegTech has recently brought great success to financial compliance, resulting in reduced risk, cost saving and enhanced financial regulatory compliance. It is shown that many GDPR solutions lack interoperability features such as standard APIs, meta-data or reports and they are not supported by published methodologies or evidence to support their validity or even utility. A proof of concept prototype was explored using a regulator based self-assessment checklist to establish if RegTech best practice could improve the demonstration of GDPR compliance. The application of a RegTech approach provides opportunities for demonstrable and validated GDPR compliance, notwithstanding the risk reductions and cost savings that RegTech can deliver. This paper demonstrates a RegTech approach to GDPR compliance can facilitate an organisation meeting its accountability obligations.

description: This review describes the observational properties of radio pulsars, fast rotating neutron stars, emitting radio waves. After the introduction we give a list of milestones in pulsar research. The following chapters concentrate on pulsar morphology: the characteristic pulsar parameters such as pulse shape, pulsar spectrum, polarization and time dependence. We give information on the evolution of pulsars with frequency since this has a direct connection with the emission heights, as postulated in the radius to frequency mapping (RFM) concept. We deal successively with the properties of normal (slow) pulsars and of millisecond (fast-recycled) pulsars. The final chapters give the distribution characteristics of the presently catalogued 1300 objects.

description: We discuss the quasi-normal modes of massive scalar perturbations of black holes in AdS_5 in conjunction with the AdS/CFT correspondence. On the gravity side, we solve the wave equation and obtain an expression for the asymptotic form of quasi-normal frequencies. We then show that these expressions agree with those obtained from a CFT defined on $\mathbb{R} \times S^3$ in a certain scaling limit, by identifying Euclidean time with one of the periodic coordinates. This generalizes known exact results in three dimensions (BTZ black hole). As a by-product, we derive the standard energy quantization condition in AdS by a simple monodromy argument in complexified AdS space. This argument relies on an unphysical singularity.

description: Mobile devices have evolved from just communication devices into an indispensable part of people's lives in form of smartphones, tablets and smart watches. Devices are now more personal than ever and carry more information about a person than any other. Extracting user behaviour is rather difficult and time-consuming as most of the work previously has been manual or requires feature extraction. In this paper, a novel approach of user behavior detection is proposed with Deep Learning Network (DNN). Initial approach was to use recurrent neural network (RNN) along with LSTM for completely unsupervised analysis of mobile devices. Next approach is to extract features by using Long Short Term Memory (LSTM) to understand the user behaviour, which are then fed into the Convolution Neural Network (CNN). This work mainly concentrates on detection of user behaviour and anomaly detection for usage analysis of mobile devices. Both the approaches are compared against some baseline methods. Experiments are conducted on the publicly available dataset to show that these methods can successfully capture the user behaviors.

description: We point out that the suppression in the ratio R_dAu recently observed by the BRAHMS collaboration in forward scattering is stronger than usually appreciated. This is related to the fact that at forward rapidities BRAHMS measures negatively charged hadrons and that R_dAu is defined from the ratio of dA and pp scattering cross sections. We also investigate the influence of standard shadowing on R_dAu, and the typical values of partonic momentum fractions relevant in forward scattering. We find that x_Au > 0.02 dominate in the cross section.

description: The recent discovery of the microwave induced vanishing resistance states in a two dimensional electron system (2DES) is an unexpected and surprising phenomena. In these experiments the magnetoresistance of a high mobility 2DES under the influence of microwave radiation of frequency $ω$ at moderate values of the magnetic field, exhibits strong oscillations with zero-resistance states (ZRS) governed by the ratio $ω/ω_c$, where $ω_c$ is the cyclotron frequency. In this work we present a model for the photoconductivity of a two dimensional electron system (2DES) subjected to a magnetic field. The model includes the microwave and Landau contributions in a non-perturbative exact way, impurity scattering effects are treated perturbatively. In our model, the Landau-Floquet states act coherently with respect to the oscillating field of the impurities, that in turn induces transitions between these levels. Based on this formalism, we provide a Kubo-like formula that takes into account the oscillatory Floquet structure of the problem. We study the effects of both short-range and long-range disorder on the photoconductivity. Our calculation yields a magnetoresistance oscillatory behavior with the correct period and phase. It is found that, in agreement with experiment, negative dissipation can only be induced in very high mobility samples. We analyze the dependence of the results on the microwave power and polarization. For high-intensity radiation multi-photon processes take place predicting new negative-resistance states centered at $ ω/ ω_c=1/2$, and $ ω/ ω_c= 3/2$.

description: Artificial Neural Networks (ANNs) are increasingly being used within safety-critical Cyber-Physical Systems (CPSs). They are often co-located with traditional embedded software, and may perform advisory or control-based roles. It is important to validate both the timing and functional correctness of these systems. However, most approaches in the literature consider guaranteeing only the functionality of ANN based controllers. This issue stems largely from the implementation strategies used within common neural network frameworks -- their underlying source code is often simply unsuitable for formal techniques such as static timing analysis. As a result, developers of safety-critical CPS must rely on informal techniques such as measurement based approaches to prove correctness, techniques that provide weak guarantees at best. In this work we address this challenge. We propose a design pipeline whereby neural networks trained using the popular deep learning framework Keras are compiled to functionally equivalent C code. This C code is restricted to simple constructs that may be analysed by existing static timing analysis tools. As a result, if compiled to a suitable time-predictable platform all execution bounds may be statically derived. To demonstrate the benefits of our approach we execute an ANN trained to drive an autonomous vehicle around a race track. We compile the ANN to the Patmos time-predictable controller, and show that we can derive worst case execution timings.

Convection in galaxy-cluster plasmas driven by active galactic nuclei and cosmic-ray buoyancy

Publisher: name: arXiv
Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Turbulent heating may play an important role in galaxy-cluster plasmas, but if turbulent heating is to balance radiative cooling in a quasi-steady state, some mechanism must set the turbulent velocity to the required value. This paper explores one possible regulating mechanism associated with an active galactic nucleus at cluster center. A steady-state model for the intracluster medium is presented in which radiative cooling is balanced by a combination of turbulent heating and thermal conduction. The turbulence is generated by convection driven by the buoyancy of cosmic rays produced by a central radio source. The cosmic-ray luminosity is powered by the accretion of intracluster plasma onto a central black hole. The model makes the rather extreme assumption that the cosmic rays and thermal plasma are completely mixed. Although the intracluster medium is convectively unstable near cluster center in the model solutions, the specific entropy of the thermal plasma still increases outwards because of the cosmic-ray modification to the stability criterion. The model provides a self-consistent calculation of the turbulent velocity as a function of position, but fails to reproduce the steep central density profiles observed in clusters. The principal difficulty is that in order for the fully mixed intracluster medium to become convectively unstable, the cosmic-ray pressure must become comparable to or greater than the thermal pressure within the convective region. The large cosmic-ray pressure gradient then provides much of the support against gravity, reducing the thermal pressure gradient near cluster center and decreasing the central plasma density gradient. A more realistic AGN-feedback model of intracluster turbulence in which relativistic and thermal plasmas are only partially mixed may have greater success.

description: (abridged) A detailed examination of the evolution of stochastic magnetic fields between high cosmic temperatures and the present epoch is presented. A simple analytical model matching the results of the 3D MHD simulations allows for the prediction of present day magnetic field correlation lengths and energy. Our conclusions are multi fold. (a) Initial primordial fields with only a small amount of helicity are evolving into maximally helical fields. (b) There exists a correlation between the strength of the magnetic field, B, at the peak of it's spectrum and the location of the peak, given at the present epoch by: B ~ 5x10^{-12} (L/kpc) Gauss, where L is the correlation length determined by the initial magnetic field. (c) Concerning studies of generation of cosmic microwave background (CMBR) anisotropies due to primordial magnetic fields of B~10^{-9} Gauss on ~ 10 Mpc scales, such fields are not only impossible to generate in early causal magnetogenesis scenarios but also seemingly ruled out by distortions of the CMBR spectrum due to magnetic field dissipation on smaller scales and the overproduction of cluster magnetic fields. (d) The most promising detection possibility of CMBR distortions due to primordial magnetic fields may be on much smaller scales at higher multipoles l~10^6 where the signal is predicted to be the strongest. (e) It seems possible that magnetic fields in clusters of galaxies are entirely of primordial origin, without invoking dynamo amplification. Such fields would be of (pre-collapse) strength 10^{-12} - 10^{-11} Gauss with correlation lengths in the kpc range, and would also exist in voids of galaxies.

description: The increasing urban population imposes a substantial and growing burden on the supporting infrastructure, such as electricity, water, heating, natural gas, road transportation, etc. This paper presents a Hetero-functional graph theory (HFGT) based modeling framework for these integrated infrastructures followed by an analysis of network robustness. The supporting infrastructures along with the infrastructure repair facilities are considered. In contrast to conventional graph representations, a weighted HFGT model is used to capture the system processes and mutual dependencies among resources. To assess robustness of the inter-dependent networks, impacts of complete/partial and random/targeted attacks are quantified. Specifically, various contingency scenarios are simulated and the vulnerability of the network is evaluated. Additionally, several robustness metrics are proposed to provide a comprehensive evaluation of system robustness. The proposed weighted HFGT modeling and robustness assessment approach is tested using a synthetic interdependent network, comprising of an electrical power system, a water network, a district heating network, a natural gas system and a road transportation network. Results demonstrate that system robustness can be enhanced via securing system information and mitigating attack strength.

description: A description of dislocations and disclinations defects in terms of Riemann--Cartan geometry is given, with the curvature and torsion tensors being interpreted as the surface densities of the Frank and Burgers vectors, respectively. A new free energy expression describing the static distribution of defects is presented, and equations of nonlinear elasticity theory are used to specify the coordinate system. Application of the Lorentz gauge leads to equations for the principal chiral SO(3)-field. In the defect-free case, the geometric model reduces to elasticity theory for the displacement vector field and to a principal chiral SO(3)-field model for the spin structure. As illustrated by the example of a wedge dislocation, elasticity theory reproduces only the linear approximation of the geometric theory of defects. It is shown that the equations of asymmetric elasticity theory for the Cosserat media can also be naturally incorporated into the geometric theory as the gauge conditions. As an application of the theory, phonon scattering on a wedge dislocation is considered. The energy spectrum of impurity in the field of a wedge dislocation is also discussed.

description: We present column density measurements of the HD molecule in the interstellar gas toward 17 Galactic stars. The values for the seven most heavily reddened sightlines, with E(B-V) = 0.38-0.72, are derived from observations with the Far Ultraviolet Spectroscopic Explorer (FUSE). The other ten values are from a reanalysis of spectra obtained with Copernicus. In all cases, high-resolution ground-based observations of KI and/or the CH molecule were used to constrain the gas velocity structure and to correct for saturation effects. Comparisons of the column densities HD, CH, CN, and KI in these 17 sightlines indicate that HD is most tightly correlated with CH. Stringent lower limits to the interstellar D/H ratio, derived from the HD/2H2 ratio, range from 3.7 10^(-7) to 4.3 10^(-6). Our results also suggest that the HD/H2 ratio increases with the molecular fraction f(H2) and that the interstellar D/H ratio might be obtained from HD by probing clouds with f(H2) = 1. Finally, we note an apparent relationship between the molecular fractions of hydrogen and deuterium.

description: In the country of Uganda in Sub-Saharan Africa, a World Bank-funded development project has been implemented under the Clean Development Mechanism of the Kyoto Protocol for the purpose of improving waste management and reducing emissions from untreated household waste. This project has set up twelve active composting facilities throughout the country. The residues resulting from the composting process are currently landfilled. Municipal solid waste quantity and composition data recorded on nine of the twelve active facilities was thoroughly reviewed to show that the residues contain enough combustible material to process further to create two different forms of refuse-derived fuelone primarily composed of paper and one primarily composed of plastics. The theoretical quantitative values of each RDF was then derived, as well as their lower heat values based on their composition. It was then shown that both RDFs would serve as viable fuel replacements for clinker production in Ugandas growing cement industry, therefore reducing the demand for primary fossil-based fuel sources, and ultimately, leading to a net carbon dioxide gas emission reduction, should the alternative fuel production scheme be implemented.

The EuroFIR Food Platform

description: The eBASIS database includes online food composition and biological effects data (both beneficial and toxicological) for phytochemicals in food plants and products thereof. The database is compiled from quality-assessed, peer-reviewed literature using a standardised approach. Data exports are in a user-defined ready-to-use format. We previously showed that eBASIS is a useful tool for regulators to independently check completeness of health claims applications relating to phytochemicals and is a potentially valuable resource to assist claimants in the compilation of dossiers on functional foods and health claims. The objective of the current project is to scope the requirements to extend the application of eBASIS beyond scientific research into the commercial arena. Results of the usability testing of eBASIS carried out during the EuroFIR NoE project recommended one-to-one testing with a small number of clients to define requirements of commercial users. The current report describes outcomes of the pilot phase of this “friendly client” approach, including the process used to identify and select potential clients for the pilot and the main recommendations.

description: In the Mott insulating phase of the transition metal oxides, the effective orbital-orbital interaction is directional both in the orbital space and in the real space. We discuss a classical realization of directional coupling in two dimensions. Despite extensive degeneracy of the ground state, the model exhibits partial orbital ordering in the form of directional ordering of fluctuations at low temperatures stabilized by an entropy gap. Transition to the disordered phase is shown to be in the Ising universality class through exact mapping and multicanonical Monte Carlo simulations.

Our study covers causality (causal ladder, inexistence of horizons), geodesic completeness, geodesic connectedness and existence of conjugate points. Appropiate mathematical tools for each problem are emphasized and the necessity to improve several Riemannian (positive definite) results is claimed.

description: The Eulerian fluid simulation is an important HPC application. The neural network has been applied to accelerate it. The current methods that accelerate the fluid simulation with neural networks lack flexibility and generalization. In this paper, we tackle the above limitation and aim to enhance the applicability of neural networks in the Eulerian fluid simulation. We introduce Smartfluidnet, a framework that automates model generation and application. Given an existing neural network as input, Smartfluidnet generates multiple neural networks before the simulation to meet the execution time and simulation quality requirement. During the simulation, Smartfluidnet dynamically switches the neural networks to make the best efforts to reach the user requirement on simulation quality. Evaluating with 20,480 input problems, we show that Smartfluidnet achieves 1.46x and 590x speedup comparing with a state-of-the-art neural network model and the original fluid simulation respectively on an NVIDIA Titan X Pascal GPU, while providing better simulation quality than the state-of-the-art model.

description: The main result is a rigorous proof that artificial neural networks without explicit regularization implicitly regularize the integral of the squared second derivative. when trained by gradient descent by solving very precisely the smoothing spline regression problem := arg min C2(Ni=1((xi train)yi traini)2+(′′)2dx) under certain conditions. Artificial neural networks are often used in Machine Learning to estimate an unknown function True by only observing finitely many data points. There are many methods that guarantee the convergence of the estimated function to the true function True as the number of samples tends to infinity. But in practice there is almost always only a finite number N of samples available. Given a finite number of data points there are infinitely many functions that fit perfectly through the N data points but generalize arbitrary bad. Therefore one needs some regularization to find a suitable function. With the help of the main theorem one can solve the paradox why training neural networks without explicit regularization works surprisingly well under certain conditions (in the case of 1-dimensional wide ReLU randomized shallow neural networks).
Finite Size Effects in Thermal Field Theory

description: We consider a neutral self-interacting massive scalar field defined in a d-dimensional Euclidean space. Assuming thermal equilibrium, we discuss the one-loop perturbative renormalization of this theory in the presence of rigid boundary surfaces (two parallel hyperplanes), which break translational symmetry. In order to identify the singular parts of the one-loop two-point and four-point Schwinger functions, we use a combination of dimensional and zeta-function analytic regularization procedures. The infinities which occur in both the regularized one-loop two-point and four-point Schwinger functions fall into two distinct classes: local divergences that could be renormalized with the introduction of the usual bulk counterterms, and surface divergences that demand countertems concentrated on the boundaries. We present the detailed form of the surface divergences and discuss different strategies that one can assume to solve the problem of the surface divergences. We also briefly mention how to overcome the difficulties generated by infrared divergences in the case of Neumann-Neumann boundary conditions.
