description: PVLAS is an experiment which aims at the direct detection of photon-field scattering: it employs optical methods and a large rotating superconducting magnet, and its large, compact structure is affected by both mechanical and electrical noises. This paper introduces briefly the data analysis methods used in the experiment and summarizes the mechanical and electrical noise situation.

description: Machine reading comprehension (MRC), which requires a machine to answer questions based on a given context, has attracted increasing attention with the incorporation of various deep-learning techniques over the past few years. Although research on MRC based on deep learning is flourishing, there remains a lack of a comprehensive survey summarizing existing approaches and recent trends, which motivated the work presented in this article. Specifically, we give a thorough review of this research field, covering different aspects including (1) typical MRC tasks: their definitions, differences, and representative datasets; (2) the general architecture of neural MRC: the main modules and prevalent approaches to each; and (3) new trends: some emerging areas in neural MRC as well as the corresponding challenges. Finally, considering what has been achieved so far, the survey also envisages what the future may hold by discussing the open issues left to be addressed.

description: The data volume of Partial Differential Equation (PDE) based ultra-large-scale scientific simulations is increasing at a higher rate than that of the system’s processing power. To process the increased amount of simulation data within a reasonable amount of time, the evolution of computation is expected to reach the exascale level. One of several key challenges to overcome in these exascale systems is to handle the high rate of component failure arising due to having millions of cores working together with high power consumption and clock frequencies. Studies show that even the highly tuned widely used checkpointing technique is unable to handle the failures efficiently in exascale systems. The Sparse Grid Combination Technique (SGCT) is proved to be a cost-effective method for computing high-dimensional PDE based simulations with only small loss of accuracy, which can be easily modified to provide an Algorithm-Based Fault Tolerance (ABFT) for these applications. Additionally, the recently introduced User Level Failure Mitigation (ULFM) MPI library provides the ability to detect and identify application process failures, and reconstruct the failed processes. However, there is a gap of the research how these could be integrated together to develop fault-tolerant applications, and the range of issues that may arise in the process are yet to be revealed. My thesis is that with suitable infrastructural support an integration of ULFM MPI and a modified form of the SGCT can be used to create high performance robust PDE based applications. The key contributions of my thesis are: (1) An evaluation of the effectiveness of applying the modified version of the SGCT on three existing and complex applications (including a general advection solver) to make them highly fault-tolerant. (2) An evaluation of the capabilities of ULFM MPI to recover from a single or multiple real process/node failures for a range of complex applications computed with the modified form of the SGCT. (3) A detailed experimental evaluation of the fault-tolerant work including the time and space requirements, and parallelization on the non-SGCT dimensions. (4) An analysis of the result errors with respect to the number of failures. (5) An analysis of the ABFT and recovery overheads. (6) An in-depth comparison of the fault-tolerant SGCT based ABFT with traditional checkpointing on a non-fault-tolerant SGCT based application. (7) A detailed evaluation of the infrastructural support in terms of load balancing, pure- and hybrid-MPI, process layouts, processor affinity, and so on.

description: Associative photoproduction of $ω$-meson and $N^{*}(1440)$ on nucleons, $γ+N\toω+N^{*}(1440)$, in the near threshold region is investigated in a framework employing effective Lagrangians. Besides $π$-exchange in t-channel, baryon exchanges, i.e. N- and $N^{*}$-exchanges, in the s- and u-channels are also taken into account in calculations of differential cross-section and beam asymmetry. Important inputs of this model are the vector and tensor coupling constants of $ωNN^{*}(1440)$-vertex, which are assumed to be equal to the values of these couplings for $ωNN$ vertex. Using our previous estimation of $ωNN$ coupling constants obtained from a fit to available experimental data on photoproduction of $ω$ meson in the near threshold region, we produce the necessary numerical predictions for different observables in $γ+N\toω+N^{*}(1440)$. Numerical results shows that at low $|$t$|$ dominant contribution comes from t-channel $π$-exchange while effects of nucleon and $N^{*}(1440)$ pole terms can be seen at large $|t|$. Our predictions for the differential cross section and beam asymmetry for the processes $γ+N\toω+N^{*}(1440)$, where N is proton and neutron at $E_γ=2.5$ GeV are presented with zero width approximation and also with the inclusion of width effects of $N^{*}(1440)$.

title: Paramedic Clinical Judgement and Decision-Making of Mental Illness in the Pre-Hospital Emergency Care Setting: A Case Study of Accounts of Practice
Creators: name: Shaban, Ramon Zenel

Year: 2011
Subjects: subject: Queensland Ambulance Service

subject: Mental illness clinical assessment

description: The introduction of legislation governing the management of mental illness in Queensland led to complaints from paramedics and their industrial association to the Commissioner of the Queensland Ambulance Service regarding the inadequacy of education and training to fulfil their new practice obligations. The industrial association asserted that their members were ill-prepared, insufficiently skilled, and unsupported professionally to make clinical judgements and decisions about mental illness in the pre-hospital emergency care setting. Furthermore, they raised concerns that their members were at significant risk of harm from patients with mental illness, and that they were vulnerable to litigation for actions of negligence and breaches of duty of care that were a direct result of the inadequacy of their education and training. These concerns, coupled with a lack of published literature that might address them, highlighted the need for a deeper understanding of how paramedics accomplish clinical judgement and decision-making of mental illness in the field, and the factors that influence this aspect of their work. Integral to the concerns were questions about the relationship between the formal expectations of paramedic practice—in the form of legislation and clinical policy—and their actual judgement practice in the field. At issue in this study was the preparedness of paramedics to recognise, assess, and manage mental illness in everyday practice and the sufficiency of education and training programs, clinical standards, policy, and legislation for ensuring quality practice and accountability in the field. To understand how paramedics accomplish clinical judgement and decision-making of mental illness in the Queensland pre-hospital emergency care setting and the factors that influence this aspect of their work, this thesis adopted a descriptive theoretical framework of judgement and decision-making (Bell, Raiffa, & Tversky, 1988a) and undertook an interpretive, naturalistic case study according to Stake (1995). In this study, the cases were paramedics, the context was the Queensland pre-hospital emergency care setting, and the issue was how they accomplished clinical judgement and decision-making of mental illness. The study of paramedic clinical judgement and decision-making of mental illness was conducted in two iterative and recursive phases.

 Distribution:— India, endemic (Kerala and Tamil Nadu).
 Notes:— Wight & Arnott (1834) described Millettia rubiginosa based on the collections of Wight (Wight 912) from Courtallum in south India. Pertaining to the type specification provided in protologue, 13 specimens were traced in various herbaria across the globe. Robert Wight was an assistant surgeon and botanist in the service of East India Company in Madras and served as superintendent of Madras Botanic Garden during 1826–1828. He returned to England on a three-years furlough due to physical problems and spent most of this period in Edinburgh to work on his material for the Prodromus (Basak 1981). G.A.W. Arnott was a botanist and Professor of Botany in the University of Glasgow from 1845 to 1868. The specimens housed at E and K must have been used by the authors to describe M. rubiginosa. Of these, K000848706 is designated here as the lectotype as it agrees well with the protologue.

Clockwork origin of neutrino mixings

description: The clockwork mechanism provides a natural way to obtain hierarchical masses and couplings in a theory. We propose a clockwork model that has nine clockwork generations. In this model, the candidates of the origin of the neutrino mixings are nine Yukawa mass matrix elements $Y^{aβ}$ that connect neutrinos and clockwork fermions, nine clockwork mass ratios $q_{aβ}$, and nine numbers of clockwork fermions $n_{aβ}$, where $a, β=1,2,3$. Assuming $|Y^{aβ}|=1$, the neutrino mixings originate from the pure clockwork sector. We show that the observed neutrino mixings are exactly obtained from a clockwork model in the case of the $q_{aβ}$ origin scenario. In the $n_{aβ}$ origin scenario, the correct order of magnitude of the observed neutrino mixings is obtained from a clockwork model.

 Distribution:— India, endemic (Kerala and Tamil Nadu).
 Notes:— Wight & Arnott (1834) described Millettia splendens based on the collection Wight 998. The collection locality and date are not mentioned in the protologue. Six specimens of M. splendens collected by Wight were traced (CAL0000012590, E00174565, K000848703, K000848704, M0233439 and P 02141868). Of these, K000848703 is chosen here as the lectotype as it well exhibits the diagnostic characters of the species mentioned in the protologue. The exact collection locality, Ballsar, Neelgheries is written on this sheet in Wight’s hand. In the specimens deposited at CAL and M, the collection number was labelled as ‘807’, which was probably a mistake happened during remounting. Wight Cat. n. 807 is Alysicarpus nummularifolius DC. (1825: 353) and 802 to 809 are pertaining to different species of Alysicarpus. The specimens in CAL and K are examined by Dunn during the revisionary studies of the genus Millettia and labelled as ‘typus’.

description: Magnetic fields penetrate a type-II superconductor as magnetic flux quanta, called vortices. In a clean superconductor they arrange in a hexagonal lattice, while by adding periodic artificial pinning centers many other arrangements can be realized. Using the focused beam of a helium ion microscope we have fabricated periodic patterns of dense pinning centers with spacings as small as 70 nm in thin films of the cuprate superconductor YBa$_{2}$Cu$_{3}$O$_{7-δ}$. In these ultradense kagomé-like patterns, the voids lead to magnetic caging of vortices, resulting in unconventional commensurability effects that manifest themselves as peaks in the critical current and minima in the resistance versus applied magnetic field up to $\sim 0.4\,$T. The various vortex patterns at different magnetic fields are analyzed by molecular dynamics simulations of vortex motion, and the magnetic field dependence of the critical current is confirmed. These findings open the way for a controlled manipulation of vortices in cuprate superconductors by artificial sub-100 nm pinning landscapes.

Abundances of 30 elements in 23 metal-poor stars

description: We report the abundances of 30 elements in 23 metal-poor ([Fe/H] 0.10 dex, the relative abundances, especially between closely allied atoms such as the rare earth group, often show only small (<0.03 dex) changes. We found that some strong lines of FeI, MnI and CrI consistently gave lower abundances by ~0.2 dex, a number larger than the quoted errors in the gf values. After considering a model with depth-dependent microturbulent velocity and a model with hotter temperatures in the upper layers, we conclude that the latter did a better job of resolving the problem and agreeing with observational evidence for the structure of stars. The error analysis includes the effects of correlation of Teff, log g, and microturbulent velocity errors, which is crucial for certain element ratios, such as [Mg/Fe]. The abundances presented here are being analyzed and discussed in a separate series of papers.

description: We live in an increasingly interconnected, complex world, where our collective decisions can have unanticipated indirect consequences on the world. What is today a hands-on job may soon be a job of managing variables at a computer screen. However, people have tremendous difficulty handling even relatively mild levels of complexity in experiments. Yet, in the context of many modern computer games, people eagerly teach themselves vastly complex systems, all without any external guidance or coercion. Educational video games research is a menagerie of different methodologies and paradigms. Meta analyses have found that mixed results in the literature are difficult to interpret due to the combination of different theoretical approaches, different data reporting conventions, and a general focus on proof-of-concept studies. They recommend a transition to narrower investigations of specific causal relationships between game properties and outcomes of engagement and learning, but this requires a way to incorporate them into the broader picture of educational and serious games research. In this thesis, I focus on educational games and propose the Model-Master-Transfer (MMT) framework to break down educational game usage into a set of formal subprocesses that can be studied in more depth individually, and specify how such narrow studies can then be assembled to build up a causal model of the underlying effects. The framework is illustrated using different educational examples. The conceptual study contributes a comprehensive framework to the ambiguous research on educational learning using games. MMT is then used in empirical experiments to address two sub-problems: 1) Why players sometimes choose to lose the game, completely derailing its intended purpose; 2) The design of inherently learnable systems in terms of how the complexity of a game relates to the player’s ability to master it - searching for forms of complexity that elicit curiosity to learn about that complexity. These experiments demonstrate the value and manner of how to apply MMT to investigate specific psychological phenomena while retaining a logically coherent place in our understanding of how educational and serious games achieve positive outcomes - a logically coherent place provided by the framework ofMMT. This body of work provides practical applications for game developers and educators alike, as well as interesting theoretical implications for cognition, curiosity, and complexity.
A reference grammar of Paiwan
Creators: name: Chang, Anna Hsiou-Chuan
Publisher: name: The Australian National University
Year: 2006

description: This thesis is a grammatical description ofNorth Paiwan, spoken in Santimen and Saichia townships in Pingtung County, Taiwan. This language is predicate-initial. Order of the arguments is flexible, as there is a preceding case marker indicating their syntactic role. Paiwan has fairly rich morphology. Like most Formosan languages, it has four morphologically marked voices: Actor Voice (A V), Goal Voice (GV), Instrument Voice (IV) and Locative Voice (LV). GV, IV and LV can be grouped under the heading ofNon-actor Voice (NAV). Topicality is the main factor determining choice among voice constructions. Although the alignment of argument case marking is seemingly consistent with ergativity, morphologically Paiwan is neither ergative nor accusative because neither A V Clauses nor NA V clauses are attested to be more basic. It is thus better classes as a morphologically symmetrical language. Syntactically it is not entirely a symmetrical language. Paiwan A V verbs may be transitive because an oblique argument may also bear some properties of core arguments. However, NAV verbs are more transitive than AV verbs. Syntactically, Paiwan resembles Tagalog, standing somewhere between ergativity and symmetricality. This thesis consists of fifteen chapters. Chapter 1 introduces the language, its speakers and the areas where they live. Chapter 2 describes the phonetics and phonology. Chapter 3 deals with reduplication and some morphophonemic processes. An overview of Paiwan main clause structures, including verbal clauses and nonverbal clauses, is provided in Chapter 4. Chapter 5 treats major and minor word classes. Paiwan major word classes include verbs, nouns and adjectives. Chapter 6 deals with the derivation of complex stems. Chapter 7 analyses the structure of the noun phrase. Chapter 8 treats verbs and verbal predicates. Verbal focus morphology and valence-changing morphology, including causatives, anticausatives, reflexives and reciprocals, are described, as are verbal auxiliaries. Chapter 9 introduces verb serialization. Chapter 10 describes interrogative and imperative clauses. Chapter 11 introduces some complex constructions, discourse connectors and inferential markers. Chapter 12 describes relative clauses. Chapter 13 deals with complement clauses. Argument raising in a tu complement clause is examined. The pragmatic function of the Paiwan voice system is discussed in Chapter 14. Chapter 15 examines the syntax of the Paiwan voice system.
A Two Dimensional Tunneling Resistance Transmission Line Model for Nanoscale Parallel Electrical Contacts

description: Contact resistance and current crowding are important to nanoscale electrical contacts. In this paper, we present a self-consistent model to characterize partially overlapped parallel contacts with varying specific contact resistivity along the contact length. For parallel tunneling contacts formed between contacting members separated by a thin insulating gap, we examine the local voltage-dependent variation of potential barrier height and tunneling current along the contact length, by solving the lumped circuit transmission line model (TLM) equations coupled with the tunneling current self consistently. The current and voltage distribution along the parallel tunneling contacts and their overall contact resistance are analyzed in detail, for various input voltage, electrical contact dimension, and material properties (i.e. work function, sheet resistance of the contact members, and permittivity of the insulating layer). It is found the existing one-dimensional (1D) tunneling junction models become less reliable when the tunneling layer thickness becomes smaller or the applied voltage becomes larger. In these regimes, the proposed self-consistent model may provide a more accurate evaluation of the parallel tunneling contacts. This work provides insights on the design, and potential engineering, of nanoscale electrical contacts with controlled current distribution and contact resistance via engineered spatially varying contact layer properties and geometry.

description: Workers can be exposed to solid airborne particles in some occupational environments, and they might be required to wear chemical protective clothing to prevent skin exposure. Dedicated standards exist to certify the protective value of such clothing, but they are not informative enough to identify the main pathways of entry for solid particles nor to compare performances between different chemical protective clothing. In this work, 20 non-woven fabrics used to make chemical protective clothing for solid particle protection were selected to be examined for both filtration and comfort performances. Nine were microporous fabrics (MP), 10 were multilayered nonwoven fibrous media (SMS) and one was a flash spun material (FS). To assess their filtration performances, fabrics were challenged in a benchtop wind tunnel with a 20–3,000 nm diameter sodium chloride aerosol at three low fabric face velocities (0.05, 0.15, 0.3 cm/sec). Airflow resistance and water vapor transmission rate were also measured to provide indications of comfort for the wearer. The penetration results led to the classification of the 20 fabrics into distinct groups of filtration efficiency. The data were analysed based on the porous media characteristics (thickness, fiber diameter, porosity, etc.). MPs were the most efficient fabrics, and SMSs showed a wide range of performances, mostly due to variations in the thickness of the filtering layer as well as to the fabric treatment. Measurements of airflow resistance and water vapor transmission rates revealed major differences between MPs and FSs and SMSs. This highlights the potential of some SMS fabrics to meet a compromise between protection and comfort.
Water Vapor in Carbon-rich AGB Stars from the Vaporization of Icy Orbiting Bodies

description: We argue that the presence of water vapor in the circumstellar outflow of a carbon-rich AGB star is potentially a distinctive signature of extra-solar cometary systems. Detailed models show that at suitable distances from the star, water ice can survive well into the carbon-rich AGB phase; water vapor abundances as large as 10^-6 could result from the vaporization of a collection of orbiting icy bodies with a total mass comparable to what might have been originally present in the solar system's Kuiper Belt. In particular, the recently-reported detection by the Submillimeter Wave Astronomy Satellite of water vapor in the circumstellar outflow of IRC+10216 can be explained if ~10 Earth masses of ice is present at a distance ~300 AU from that carbon-rich star. Future observations with the Herschel Space Observatory (HSO, formerly known as FIRST) will facilitate sensitive multi-transition observations of water, yielding line ratios that can establish the radial distribution of water vapor in IRC+10216. The greater sensitivity of HSO will also allow searches for water vapor to be carried out in a much larger sample of carbon-rich AGB stars.

description: We develop a model-independent analysis of hadronic scattering data in the resonance region, where the resonance shape follows from the matrix elements of a Hamiltonian. We investigate the rho meson in the tau decay. We demonstrate that the rho meson resonance in the two-pion decay of the tau lepton is described well through the coupling of a bare rho meson to the two-pion and the four-pion continuum. Furthermore, this four-pion continuum corresponds with the data of the four-pion decay channel of the tau lepton at energies up to 1.1 GeV.

description: At the Helmholtz Association, we strive to establish a well-formed harmonized data space, connecting information across distributed data infrastructures. This requires standardizing the description of data sets with suitable metadata to achieve interoperability and machine actionability.

One way to make connections between datasets and to avoid redundancy in metadata is the consistent use of Persistent Identifiers (PIDs). A lot of information within the metadata such as people, organizations, projects, laboratories, repositories, publications, vocabularies, samples, instruments, licenses, and methods should be commonly referenced by PIDs, but not for all of these agreed identifiers exist yet.

Typically, researchers who are publishing datasets are also tasked with compiling the metadata for those datasets. However, researchers are usually not in charge of a lot of information that should be part of the documentation of a dataset. They often have to rely on information they receive from other sources, e.g. technicians, responsible for the measuring devices or librarians, who are experts in assigning licenses. Starting from PID Systems ROR, ORCID, IGSN, PIDInst, DataCiteDOI and CrossRef DOI we suggest to share the load, and assign certain expert stakeholder groups responsibility to maintain specific information and to conduct certain tasks within the research data management (RDM) workflow.

The conclusions from this process do not only affect the implementation of PID metadata, but may also be used for the harmonization of vocabularies, digital objects, interfaces, licenses, quality flags and others, in order to connect our global data systems, to redefine stakeholder responsibility and to ultimately reach the data space.

description: We find the constraints on various non-standard interactions (NSI) of neutrinos from monojet+MET searches at the Large Hadron Collider (LHC). Also, we show that the measurement of neutrino-nucleon cross-section from the observation of high energy astrophysical neutrino events at IceCube facilitates strong constraints on NSI as well. To this end, we pursue a comparative study of the prospects of LHC and IceCube in detecting NSI, also mentioning the role of low-energy experiments. We discuss the case of NSI with a new vector boson $Z'$ and it is found that for some range of $m_{Z'}$ LHC puts more stringent bound, whereas IceCube supersedes elsewhere. We also pay special attention to the case of $Z'$ of mass of a few GeVs, pointing out that the IceCube constraints can surpass those from LHC and low-energy experiments. Although, for contact-type effective interactions with two neutrinos and two partons, constraints from LHC are superior.

description: We study the jamming phase diagram of sheared granular material using a novel Couette shear set-up with multi-ring bottom. The set-up uses small basal friction forces to apply a volume-conserving linear shear with no shear band to a granular system composed of frictional photoelastic discs. The set-up can generate arbitrarily large shear strain due to its circular geometry, and the shear direction can be reversed, allowing us to measure a feature that distinguishes shear-jammed from fragile states. We report systematic measurements of the stress, strain and contact network structure at phase boundaries that have been difficult to access by traditional experimental techniques, including the yield stress curve and the jamming curve close to $ϕ_{SJ}\approx 0.74$, the smallest packing fraction supporting a shear-jammed state. We observe fragile states created under large shear strain over a range of $ϕ< ϕ_{SJ}$. We also find a transition in the character of the quasi-static steady flow centered around $ϕ_{SJ}$ on the yield curve as a function of packing fraction. Near $ϕ_{SJ}$, the average contact number, fabric anisotropy, and non-rattler fraction all show a change of slope. Above $ϕ_{F}\approx 0.7$ the steady flow shows measurable deviations from the basal linear shear profile, and above $ϕ_c\approx 0.78$ the flow is localized in a shear band.

description: We report the first detailed decay studies of trapped metastable (2S) hydrogen. By two-photon excitation of ultracold H samples, we have produced clouds of at least 5x10^7 magnetically trapped 2S atoms at densities greater than 4x10^10 cm^-3 and temperatures below 100 \muK. We derive experimental values for the total 2S-2S two-body loss rate constant in this temperature regime. Our results are in the range of recent theoretical calculations. We also find experimental upper limits on the rate constant for loss due to inelastic 1S-2S collisions.

description: Distributed computing and computational optimisation algorithms are often applied to design problems in various engineering disciplines. In electromagnetic compatibility, an area of electrical engineering concerned with the unintentional generation of and susceptibility to electromagnetic energy, distributed optimisation techniques could be used to ensure compliance with various civilian and military standards that most electrical devices must meet. While there are a variety of numerical techniques that can be applied to problems in computational electromagnetic compatibility, the finite-difference time-domain (FDTD) method stands out as it allows a wide range of frequencies to be examined in a single simulation using Fourier analysis. This property is important for electromagnetic compatibility problems, as resonant frequencies are usually not known or easily calculable. The efficacy of the application of the FDTD method to electromagnetic compatibility problems is limited, however, by a need for excitation sources which can accurately represent the device being modelled. Computational electromagnetic simulations have long been used in many engineering fields to numerically examine the performance of a wide variety of systems. Using such numerical methods, it is possible to examine the influence that any number of input parameters or stimuli have on the design. Optimisation algorithms are often used in conjunction with these numerical simulations to automate the design process.
title: Adsorption of CO2 by Coal and Activated Carbon: A Study Using In-situ Small-Angle X-ray Scattering and Sorption Manometry

description: Carbon capture and storage in unmineable coal seams has been recognised as one of several possible means for mitigating anthropogenic green-house-gas emissions into the atmosphere. However, implementation of this technology on the industrial scale required to significantly reduce CO2 emissions is inhibited by the lack of understanding of many aspects of the interactions between the injected CO2 fluid and coal microstructure. This thesis introduces and details the aspects of the techniques of sorption manometry and small-angle X-ray scattering applicable to the investigation of CO2 adsorption by coal. The experimental work is divided into three sections: the first investigates a self-consistent method for determining the helium density of a microporous material, the second assesses the reliability of manometric measurements of CO2 uptake by small samples, and the third presents an in-situ small-angle X-ray scattering study of CO2 and Xe adsorption by Baralaba coal and Takeda 4A activated carbon. An established self-consistent method for determining the helium density of a microporous material from gravimetric helium sorption data was reworked for application to manometric sorption data. The method was applied to a data set of four He isotherms obtained for a sample of activated carbon at 77, 87, 195 and 298 K using the manometric technique, yielding an unrealistic helium density value of 1.06 g/cm3. It was found that the sensitivity of the method to sample density was too low to provide a reliable measure of the helium density, owing to insufficient variation in the temperature dependency of the Henry constant for temperatures above room-temperature. Assuming negligible helium adsorption at low-pressure (P ≤ 1 bar) and room-temperature remains the best method at present for determining the helium density of a microporous material. Application of this method yielded a helium density value of 2.01 g/cm3 for the activated carbon sample studied.
