X-ray outflows of active galactic nuclei warm absorbers: A 900 ks
  Chandra simulated spectrum

We report on the performance of the statistical, X-ray absorption lines
identification procedure XLINE-ID. As illustration, it is used to estimate the
time averaged gas density $n_H(r)$ of a representative AGN's warm absorber
($T\approx 10^5$~K) X-ray simulated spectrum. The method relies on three key
ingredients: (1) a well established emission continuum level; (2) a robust grid
of photoionisation models spanning several orders of magnitude in gas density
($n_H$), plasma column density ($N_H$), and in ionization states; (3)
theoretical curves of growth for a large set of atomic lines. By comparing
theoretical and observed equivalent widths of a large set of lines, spanning
highly ionized charge states from O, Ne, Mg, Si, S, Ar, and the Fe L-shell and
K-shell, we are able to infer the location of the X-ray warm absorber.Comment: 18 pages, 10 figures. Accepted in book: Recent Advances in Fluid

This case study explores the challenges and successes that the University of the Fraser Valley had with Bibliographic/holding data transfer and other customizations between their ILS (SirsiDynix Symphony) and EBSCO Discovery Service. Two sets of data transfer will be considered: the identification and transfer of deleted ILS MARC records to the EDS, and the EDS inclusion of a dynamic location map, from UFV’s library catalogue, in the EDS layer. Technical details are included.Peer reviewedCorrected ProofWeb-Scale discovery interface EBSCO Discovery Service Integrated Library Systems (ILS) Library catalog MARC record Bibliographic data Holding dat
A Stochastic Multi-scale Approach for Numerical Modeling of Complex
  Materials - Application to Uniaxial Cyclic Response of Concrete

In complex materials, numerous intertwined phenomena underlie the overall
response at macroscale. These phenomena can pertain to different engineering
fields (mechanical , chemical, electrical), occur at different scales, can
appear as uncertain, and are nonlinear. Interacting with complex materials thus
calls for developing nonlinear computational approaches where multi-scale
techniques that grasp key phenomena at the relevant scale need to be mingled
with stochastic methods accounting for uncertainties. In this chapter, we
develop such a computational approach for modeling the mechanical response of a
representative volume of concrete in uniaxial cyclic loading. A mesoscale is
defined such that it represents an equivalent heterogeneous medium: nonlinear
local response is modeled in the framework of Thermodynamics with Internal
Variables; spatial variability of the local response is represented by
correlated random vector fields generated with the Spectral Representation
Method. Macroscale response is recovered through standard ho-mogenization
procedure from Micromechanics and shows salient features of the uniaxial cyclic
response of concrete that are not explicitly modeled at mesoscale.Comment: Computational Methods for Solids and Fluids, 41, Springer

Predicting adverse drug events from electronic medical records

Learning from electronic medical records (EMR) poses many challenges from a knowledge representation point of view.  This chapter focuses on how to cope with two specific challenges: the relational nature of EMRs and the uncertain
  dependence between a patient's past and future health status.   We discuss three different approaches for allowing standard propositional learners to incorporate relational information.  We evaluate these approaches   on three real-world tasks where the goal is to use EMRs to predict  whether a patient will have an adverse reaction to a medication.status: publishe
Moment Closure - A Brief Review

Moment closure methods appear in myriad scientific disciplines in the
modelling of complex systems. The goal is to achieve a closed form of a large,
usually even infinite, set of coupled differential (or difference) equations.
Each equation describes the evolution of one "moment", a suitable
coarse-grained quantity computable from the full state space. If the system is
too large for analytical and/or numerical methods, then one aims to reduce it
by finding a moment closure relation expressing "higher-order moments" in terms
of "lower-order moments". In this brief review, we focus on highlighting how
moment closure methods occur in different contexts. We also conjecture via a
geometric explanation why it has been difficult to rigorously justify many
moment closure approximations although they work very well in practice.Comment: short survey paper (max 20 pages) for a broad audience in

Analytical, Optimal, and Sparse Optimal Control of Traveling Wave
  Solutions to Reaction-Diffusion Systems

This work deals with the position control of selected patterns in
reaction-diffusion systems. Exemplarily, the Schl\"{o}gl and FitzHugh-Nagumo
model are discussed using three different approaches. First, an analytical
solution is proposed. Second, the standard optimal control procedure is
applied. The third approach extends standard optimal control to so-called
sparse optimal control that results in very localized control signals and
allows the analysis of second order optimality conditions.Comment: 22 pages, 3 figures, 2 table
Dynamics of fully coupled rotators with unimodal and bimodal frequency
  distribution

We analyze the synchronization transition of a globally coupled network of N
phase oscillators with inertia (rotators) whose natural frequencies are
unimodally or bimodally distributed. In the unimodal case, the system exhibits
a discontinuous hysteretic transition from an incoherent to a partially
synchronized (PS) state. For sufficiently large inertia, the system reveals the
coexistence of a PS state and of a standing wave (SW) solution. In the bimodal
case, the hysteretic synchronization transition involves several states.
Namely, the system becomes coherent passing through traveling waves (TWs), SWs
and finally arriving to a PS regime. The transition to the PS state from the SW
occurs always at the same coupling, independently of the system size, while its
value increases linearly with the inertia. On the other hand the critical
coupling required to observe TWs and SWs increases with N suggesting that in
the thermodynamic limit the transition from incoherence to PS will occur
without any intermediate states. Finally a linear stability analysis reveals
that the system is hysteretic not only at the level of macroscopic indicators,
but also microscopically as verified by measuring the maximal Lyapunov
exponent.Comment: 22 pages, 11 figures, contribution for the book: Control of

Effect of Social and Institutional Fragmentation on Collective Action in Peri- Urban Settings

Voluntary collective action is essential to natural resource governance. In peri-urban settings, a complex behavioural and institutional matrix frames such action, and the net balance of incentives and disincentives, supports and impediments determines the likelihood of effective action on any issue. Coupled with this, each issue has its own biophysical and social characteristic, which intersects with the character of the community. Taken together these issues suggest the need for a realistic understanding of what will make collective action feasible, and design of institutional arrangements to manage the totality of the behavioural setting and the reality of the problem being addressed. Taking invasive species (and in particular invasive animals) as an example, this chapter explores the dynamic nature of the challenge of collective action in a peri-urban setting.Full Tex
Planning Development to Reduce Mosquito Hazard in Coastal Peri-Urban Areas: Case Studies in NSW, Australia

In this chapter we take a multidisciplinary approach to evaluating planning for coastal development, particularly in peri-urban areas. We consider ecosystem services and disservices and how, in the past, much development was at the expense of coastal wetlands. We then focus on mosquito production as a wetland related disservice that affects residents and imposes costs on individuals and government from both a health and management perspective. Most coastal peri-urban areas including adjacent wetland sites retain legacy infrastructures and landforms that degrade wetland function and often exacerbate the mosquito hazard. Rehabilitating coastal wetlands can improve wetland function while also reducing the mosquito hazard. Yet examination of rehabilitation and mosquito management within the existing planning framework found deficiencies and complexity. In particular, coastal wetlands are almost always overlaid with a number of different zone and ownership boundaries that increase complexity of both mosquito management and wetland rehabilitation actions. We illustrate the issues with two case studies from northern New South Wales (NSW), Australia: a greenfield development located in Ballina and a retrofitted site at Banora Point near Tweed Heads. We recommend land use planning frameworks incorporate a trigger for both assessment of adjacent coastal wetland ecosystem function and restoration of wetland ecological processes that includes provision for habitat based source control of mosquito hazard and coastal wetland rehabilitation.Full Tex
Angiogenesis in Health, Disease and Malignancy

Vasculogenesis is the de novo formation of blood vessels by mesodermal progenitors undergoing differentiation to endothelial cells. New vasculature formation from pre-existing vasculature occurs through the physiological remodelling process known as angiogenesis. Angiogenesis is implicated in the proliferation and growth of both physiologically normal and neoplastic tissues, through the establishment of vascular supply, essential for delivering growth requirements such as oxygen and nutrients. Many inhibitory and promoter genes regulate this process, however the role of specific genes in the shift from normal angiogenesis to tumour initiation is complex and thus poorly understood. This book investigates the process of angiogenesis in malignancies. The functional role of key regulatory factors will be examined in the context of normal healthy condition. Then the association of these factors to disease and malignancy, cancer proliferation and progression will be discussed. New insights into the role of angiogenesis and the therapeutic inhibition of its regulators will be investigated due to the great potential for exploitation in the development of a novel treatment for cancer.Griffith Health, School of MedicineFull Tex
Generic Construction of UC-Secure Oblivious Transfer

International audienceWe show how to construct a completely generic UC-secure oblivious transfer scheme from a collision-resistant chameleon hash scheme (CH) and a CCA encryption scheme accepting a smooth projective hash function (SPHF). Our work is based on the work of Abdalla et al. at Asiacrypt 2013, where the authors formalize the notion of SPHF-friendly commitments, i.e. accepting an SPHF on the language of valid commitments (to allow implicit decommitment), and show how to construct from them a UC-secure oblivious transfer in a generic way. But Abdalla et al. only gave a DDH-based construction of SPHF-friendly commitment schemes, furthermore highly relying on pairings. In this work, we show how to generically construct an SPHF-friendly commitment scheme from a collision-resistant CH scheme and an SPHF-friendly CCA encryption scheme. This allows us to propose an instanciation of our schemes based on the DDH, as efficient as that of Abdalla et al., but without requiring any pairing. Interestingly, our generic framework also allows us to propose an instantiation based on the learning with errors (LWE) assumption. For the record, we finally propose a last instanciation based on the decisional composite residuosity (DCR) assumption
The participatory medicine attitudes of general practitioners in Greece: an information behaviour perspectives.

General Practitioners (GPs) need to keep up with a wide range of medical conditions and at the same time closely interact with their patients to provide preventive care and health education. This requires effectively sourcing, utilizing, and sharing quality information with their patients as well as creating participatory and shared decision-making health environments. This paper explores the information seeking behaviour of GPs and their attitudes towards participatory medicine (PM). A questionnaire based survey with GPs in Greece, registered with the Hellenic Society of General Practitioners (HSGP) was conducted and included an exploration of three different information seeking dimensions (information needs, sources and barriers) that were associated with GPs' perceptions of PM. The survey results demonstrate an interplay of demographic and contextual factors in the choice of information sources and the barriers encountered and conclude that the effective utilization of online information sources is an essential condition for PM practices
The more they tried it the less they liked it:Norwegian and Romanian student’s response to electronic course material

In this paper we will present and compare survey findings from Romania and Norway taken from the “Multinational study on students’ preferences regarding print versus electronic resources for course readings”. This study was conducted in April 2015 and surveyed undergraduate, graduate and postgraduate students of various subjects at different universities. The aim was to investigate students’ format preferences when engaging with academic readings and what factors impact their preferences and behaviors. The comparative study will show whether students’ reading format preferences vary or remain consistent across multi-national student populations. We also make comparisons with results from an earlier study of Romanian and Norwegian students’ attitudes towards using academic libraries. In particular, we look at the reasons given for preferring course readings in either electronic or print format, and we discuss what this could mean for collection development policies.The final publication is available at Springer via http://dx.doi.org/10.1007/978-3-319-28197-1_4
Learning Scholarly Information Competencies in the Community of Practice: A Case Study of Polish Critical Pedagogy Researchers

University of Lower Silesia, decision number 04/dok/WGW/2015.The present paper presents the findings of research conducted in 2014/2015. The aim of the research was to understand how members of a particular academic community learn scholarly information competencies, wherein learning was perceived as a social and cultural phenomenon and, especially, as a practice. The research methodology was based on semi-structured interviews with individual members of the community and focus-group interviews. The community under study consisted of Polish critical pedagogy researchers. My investigations drew on Schatzki, Lave, and Wenger for the theoretical and philosophical underpinnings of the qualitative data analysis. The research showed that being a part of the community of practice offers multiple opportunities to learn scholarly information literacy. However, at the same time, being inside and co-creating a community does not necessarily entail new scholarly information competencies since the group may hinder the inclusion of new practices.Faculty of Education of the University of Lower Silesia, decision number 04/dok/WGW/201
Forbidden integer ratios of consecutive power sums

Let $S_k(m):=1^k+2^k+\cdots+(m-1)^k$ denote a power sum. In 2011 Bernd
Kellner formulated the conjecture that for $m\ge 4$ the ratio $S_k(m+1)/S_k(m)$
of two consecutive power sums is never an integer. We will develop some
techniques that allow one to exclude many integers $\rho$ as a ratio and
combine them to exclude the integers $3\le \rho\le 1501$ and, assuming a
conjecture on irregular primes to be true, a set of density $1$ of ratios
$\rho$. To exclude a ratio $\rho$ one has to show that the Erd\H{o}s-Moser type
equation $(\rho-1)S_k(m)=m^k$ has no non-trivial solutions.Comment: 28 pages, 3 tables; accepted for publication in the book "From

The KB paradigm and its application to interactive configuration

The knowledge base paradigm aims to express domain
knowledge in a rich formal language, and to use this domain knowledge
as a knowledge base to solve various problems and tasks that arise
in the domain by applying multiple forms of inference. As such, the
paradigm applies a strict separation of concerns between information
and problem solving. In this paper, we analyze the principles and fea-
sibility of the knowledge base paradigm in the context of an important
class of applications: interactive configuration problems. In interactive
configuration problems, a configuration of interrelated objects under
constraints is searched, where the system assists the user in reaching
an intended configuration. It is widely recognized in industry that good
software solutions for these problems are very difficult to develop. We
investigate such problems from the perspective of the KB paradigm. We
show that multiple functionalities in this domain can be achieved by
applying different forms of logical inferences on a formal specification
of the configuration domain. We report on a proof of concept of this
approach in a real-life application with a banking company.status: publishe
An alternative to the Allen-Cahn phase field model for interfaces in
  solids - numerical efficiency

The derivation of the Allen-Cahn and Cahn-Hilliard equations is based on the
Clausius-Duhem inequality. This is not a derivation in the strict sense of the
word, since other phase field equations can be fomulated satisfying this
inequality. Motivated by the form of sharp interface problems, we formulate
such an alternative equation and compare the properties of the models for the
evolution of phase interfaces in solids, which consist of the elasticity
equations and the Allen-Cahn equation or the alternative equation. We find that
numerical simulations of phase interfaces with small interface energy based on
the alternative model are more effective then simulations based on the
Allen-Cahn model.Comment: arXiv admin note: text overlap with arXiv:1505.0544
High-Dimensional Stochastic Design Optimization by Adaptive-Sparse
  Polynomial Dimensional Decomposition

This paper presents a novel adaptive-sparse polynomial dimensional
decomposition (PDD) method for stochastic design optimization of complex
systems. The method entails an adaptive-sparse PDD approximation of a
high-dimensional stochastic response for statistical moment and reliability
analyses; a novel integration of the adaptive-sparse PDD approximation and
score functions for estimating the first-order design sensitivities of the
statistical moments and failure probability; and standard gradient-based
optimization algorithms. New analytical formulae are presented for the design
sensitivities that are simultaneously determined along with the moments or the
failure probability. Numerical results stemming from mathematical functions
indicate that the new method provides more computationally efficient design
solutions than the existing methods. Finally, stochastic shape optimization of
a jet engine bracket with 79 variables was performed, demonstrating the power
of the new method to tackle practical engineering problems.Comment: 18 pages, 2 figures, to appear in Sparse Grids and

Combination technique based second moment analysis for elliptic PDEs on random domains

In this article, we propose the sparse grid combination technique for the second moment analysis of elliptic partial differential equations on random domains. By employing shape sensitivity analysis, we linearize the influence of the random domain perturbation on the solution. We derive deterministic partial differential equations to approximate the random solution’s mean and its covariance with leading order in the amplitude of the random domain perturbation. The partial differential equation for the covariance is a tensor product Dirichlet problem which can efficiently be determined by Galerkin’s method in the sparse tensor product space. We show that this Galerkin approximation coincides with the solution derived from the combination technique if the detail spaces in the related multiscale hierarchy are constructed with respect to Galerkin projections. This means that the combination technique does not impose an additional error in our construction. Numerical experiments quantify and qualify the proposed method
On the evaluation potential of quality functions in community detection
  for different contexts

Due to nowadays networks' sizes, the evaluation of a community detection
algorithm can only be done using quality functions. These functions measure
different networks/graphs structural properties, each of them corresponding to
a different definition of a community. Since there exists many definitions for
a community, choosing a quality function may be a difficult task, even if the
networks' statistics/origins can give some clues about which one to choose.
  In this paper, we apply a general methodology to identify different contexts,
i.e. groups of graphs where the quality functions behave similarly. In these
contexts we identify the best quality functions, i.e. quality functions whose
results are consistent with expectations from real life applications.Comment: 14 pages, 11 tables, Advances in Network Science: 12th International
