description: Il contributo smentisce innanzitutto la distinzione tra proporzionalità ex ante e proporzionalità ex post. Esamina, poi, le due dimensioni del principio di proporzionalità nell’ambito della vigilanza bancaria, quella “verticale”, che investe il rapporto tra poteri pubblici e soggetti privati, e quella “orizzontale”, che informa la distribuzione di competenze e poteri tra i diversi ordinamenti e le diverse autorità. Evidenzia, ancora, gli occasionali contrasti “interni” tra i diversi corollari del principio stesso. Illustra, infine talune implicazioni della natura del principio di proporzionalità quale “meta-norma” che sovrintende alla collisione di principi confliggenti. The essay first denies the distinction between ex ante and ex post proportionality. Subsequently, the two dimensions of the principle of proportionality in the field of banking supervision are examined: these are the "vertical" dimension, concerning the relationship between public authorities and individuals or private entities, and the "horizontal" dimension, informing the distribution of competences and powers among different jurisdictions and authorities. Then, the possibility of “internal” conflicts among different requirements of the principle proportionality is underlined. Finally, the essay casts a light on some implications of the nature of the principle of proportionality as a "meta-norm", managing the collision of conflicting principles.

description: The short-range and tensor components of the bare nucleon-nucleon interaction induce a sizeable depletion of low momenta in the ground state of a nuclear many-body system. The self-consistent Green's function method within the ladder approximation provides an \textit{ab-initio} description of correlated nuclear systems that accounts properly for these effects. The momentum distribution predicted by this approach is analyzed in detail, with emphasis on the depletion of the lowest momentum state. The temperature, density, and nucleon asymmetry (isospin) dependence of the depletion of the Fermi sea is clarified. A connection is established between the momentum distribution and the time-ordered components of the self-energy, which allows for an improved interpretation of the results. The dependence on the underlying nucleon-nucleon interaction provides quantitative estimates of the importance of short-range and tensor correlations in nuclear systems.

description: Purpose The purpose of this study was to evaluate integrated training for aphasia (ITA), a multicomponent language-production treatment based on part–whole learning that systematically trains lexical retrieval, sentence production, and discourse-level communications. Specific research objectives were to evaluate acquisition of target structures, statistical parameters associated with learning variables, treatment generalization, and the efficacy of individual treatment components.Method ITA was administered to 3 individuals with nonfluent aphasia following a multiple-baseline, across-behaviors design. Effect size and correlational coefficients were computed to assess acquisition, generalization, and maintenance of target structures. Standardized tests and a treatment efficacy questionnaire were also completed.Results A significant treatment effect was found in 2 of the 3 participants. In addition, as is seen in normal skill acquisition, practice time and error rate were significantly correlated. All participants demonstrated evidence of generalization on standardized language measures. Only 1 participant improved, however, on the communication measures. Results of the treatment component analysis revealed significant differences in the perceived efficacy of individual therapy tasks.Conclusions Findings add to the evidence supporting multicomponent aphasia treatments, provide preliminary support for ITA and the application of a part–whole learning approach, and suggest that specific treatment components may contribute differentially to outcomes and generalization effects.
The junior British Army officer : experience and identity, 1793-1815
Creators: name: Huf, DL
Publisher: name: University Of Tasmania
Year: 2023

description: The bulk of British army officers during the French Revolutionary and Napoleonic Wars were junior officers, namely officers who held the rank of captain, or lower. Scholarship revealing the intellectual and cultural life of the British army during the Revolutionary and Napoleonic Wars is expanding; however, junior officers have received little specific scholarly attention. This thesis is the first full-length study of junior army officers, and has 'identity and experience' as its central themes. A combination of military and cultural history, this thesis examines British junior officers as products of the military and of Georgian society, and draws on histories of masculinity, family life, and national and political identities to interpret their experiences. This thesis focuses on the lived experiences of junior officers, and interrogates three main types of personal accounts, namely letters, diaries and journals, and memoirs. This group of officers developed a set of sensibilities and perspectives that were bound to their middling status within the army's hierarchy. Junior officers were imbued with significant authority over the rank and file, yet were subjected to the authority of superior officers. As some of the youngest members of the officer corps, junior officers straddled the lines between the civilian and military spheres, and between youth and adulthood. This thesis argues that the tensions inherent in such a position saw junior officers develop an identity as junior officers, which shaped other aspects of their identity. Junior officers fashioned identities as 'polite gentlemen', with the regimental mess inculcating a sense of gentlemanly value. Junior officers displayed careerist and professional ambitions, and hoped for promotion to deliver them from their subordinate position. While the honour culture of the officer corps could conflict with some new officers' sense of masculinity, junior officers found themselves embroiled in a performative culture of honour, which included fighting duels. Although military service entailed separation from family and friends, junior officers were adept at staying in touch with family members, with some officers contriving to bring their families into the field. These family bonds proved strong enough to outweigh comparatively fluid regimental loyalties. Drawing on their social standing and the language of sensibility, junior officers styled themselves as brave patriarchs, leading from the front and caring for their men. Serving within a truly 'British' army, junior officers' service had the effect of dissolving national differences, while their conceptions of patriotism broadened as the Revolutionary War gave way to war with Napoleon.

description: Fundamental symmetry tests with neutrons can provide unique information about whatever will be the new Standard Model of fundamental interactions. I review two aspects of this possibility: searches for the permanent electric dipole moment of the neutron and its relation to the origin of baryonic matter, and precision studies of neutron decay that can probe new symmetries. I discuss the complementarity of these experiments with other low-energy precision tests and high energy collider searches for new physics.

description: We perform molecular dynamics simulation of a small number of particles in a box with periodic boundary conditions from a view point of chaotic dynamical systems. There is a transition at a critical energy E_c that each particle is confined in each unit cell for EE_c. We find an anomalous behavior of the jump frequency above the critical energy in a two-particle system, which is related with the infinitely alternating stability change of the straight motion passing through a saddle point. We find simultaneous jump motions just above the critical energy in a four-particle system and sixteen-particle system, which is also related with the motion passing through the saddle point.

description: La scienza deve prendersi sostanzialmente cura delle persone, del loro benessere e dell’ambiente in cui esse vivono, sottolineando al contempo il valore della tecnologia per fare innovazione e guardare con fiducia al futuro. La ricerca scientifica ha avuto da sempre una “visione globale” dei problemi e delle relative soluzioni che essa propone e costituisce pertanto un mezzo attraverso il quale poter costruire un mondo migliore. La globalizzazione della scienza non è quindi da temere ma da incentivare. L’Europa è ben consapevole di ciò e tende a questo obiettivo. Scientific research should essentially take care of people, their well-being and the environment they live in, while underlining the value of history and technology in creating innovation and looking to the future with confidence. Science moreover has always had a “global perspective” on the problems and related solutions it proposes, and therefore constitutes a means by which to build a better world. The globalisation of science is consequently not to be feared but to be encouraged. Europe is well aware of this and aims to achieve this goal.

The phonological, morphological and syntactical patterns of standard colloquial Bengali and the Noakhali dialect
Creators: name: Morshed, Abul Kalam Manzur
Publisher: name: University of British Columbia
Year: 2010

description: Standard Colloquial Bengali (SCB) is the language used by the majority of educated speakers at the present time in Bangladesh and West Bengal. In contrast with this standard language there are dialects of Bengali sufficiently different to be unintelligible to SCB speakers. One of these is the Noakhali Dialect, spoken in the southern part of the country on the border of the Bay of Bengal. It is a somewhat isolated region, which explains at least in part the development of this divergent form of the language. The Noakhali Dialect (ND) differs from SCB at all linguistic levels; phonological, morphological and syntactical, as well as in lexicon. The aim of this thesis is to make a comparative and contrastive study of the standard language and the dialect at all these levels in order to establish the degree of their divergence. It is essentially a synchronic study, so that, in general, no attempt is made to link the present-day forms with possible ancestral sources in Sanscrit. For the phonological and morphological analyses, the generative approach of Noam Chomsky and Morris Halle has been used, which involves a study of distinctive features. Special emphasis is given to the phenomenon of gemination, and vocalic and consonantal alternation. The phonological structure of the morphemes of each language has been reduced to rules, and the sets of inflectional and derivational morphemes are described in some detail. As an approach to syntax, noun-phrase rules and verb-phrase rules have been elaborated for both languages. On the whole, however, SCB and ND differ little in their broader syntactical patterning so that a detailed study of their syntax would contribute little to a contrastive analysis. Thus the main emphasis of the present study is at the level of phonology and morphology, where significant contrasts can be brought out, once the generative theories have been adapted to suit a language like Bengali which is more highly inflected than English.

description: In this paper, we develop the notion of the linear atomic quantum coupler. This device consists of two modes propagating into two waveguides, each of them includes a localized and/or a trapped atom. These waveguides are placed close enough to allow exchanging energy between them via evanescent waves. Each mode interacts with the atom in the same waveguide in the standard way, i.e. as the Jaynes-Cummings model (JCM), and with the atom-mode in the second waveguide via evanescent wave. We present the Hamiltonian for the system and deduce the exact form for the wavefunction. We investigate the atomic inversions and the second-order correlation function. In contrast to the conventional linear coupler, the atomic quantum coupler is able to generate nonclassical effects. The atomic inversions can exhibit long revival-collapse phenomenon as well as subsidiary revivals based on the competition among the switching mechanisms in the system. Finally, under certain conditions, the system can yield the results of the two-mode JCM.

description: Excerpts from the report: In Montana, the principal function of country elevators is to buy and store grain. Here the farmer can find a ready cash grain market throughout the year. In addition, many of these elevators offer a variety of sidelines. This study is based on a survey--made in the summer of 1957--of 48 cooperative country elevators in Montana. It includes information for the year beginning in June 1956 and running through May 1957 on kind of elevator, type of structure, grain receipts and sales, storage capacity, turnover, transportation used, sidelines, and employees. Information gathered on storage problems, operating techniques, services, and costs will aid others in the grain trade in planning new elevator facilities. Although this survey was limited to cooperative elevators, the information gathered here and in the case studies will be valuable to all country elevators in Montana.
Understanding the dynamics of health policy change
Creators: name: Harpur, FS
Publisher: name: University Of Tasmania
Year: 2023

description: This thesis examines the dynamics of health policy change and uses Discursive Institutionalism (DI), explained in Chapter 2, as a lens to examine the empirical case of primary health policy in Tasmania, Australia. Health policy internationally has been slow to change from an emphasis on treating ill health to a broader focus on health improvement. There is a growing awareness that health is partly socially determined and poor health follows the gradient of relative disadvantage such that more equitable populations have better health overall. The discursive nature of the debate regarding the causes of ill health highlights the need to analyse competing frames and values that shape contemporary health policy. A DI approach is applied in the study because its emphasis on the dynamics of change provides significant insights into policy debates central to this thesis. The dissertation employs a case study approach that examines material relating to the Tasmania Health Plan (THP) in the period between September 2005 and May 2010. Tasmania has a population of 500,000 and relatively poor health outcomes compared with other Australian jurisdictions. The THP is intentional in taking a multi-agency and multi-strategy approach to improve the health of the Tasmanian population. The thesis concludes that DI is a useful theoretical lens to observe the dynamics of health policy change in practice, particularly with the diversity and volume of actors and organisations, the structures of communication, and the multiple discourses. It shows that there is potential for expertise and honest brokerage to facilitate the best outcomes between governments, citizens and private and not for profit organisations. Acknowledging complexity and adapting locally. This could open the opportunity for a revival of a civil society discourse, and an investment in policymaking leadership and capability.

description: We present three candidate clusters of galaxies at redshifts most likely between 1.7 and 2.0, which corresponds to a fundamentally unexplored epoch of clusters evolution. The candidates were found by studying the environment around our newly selected sample of "beacons" low-luminosity (FRI) radio galaxies in the COSMOS field. In this way we intend to use the fact that FRI at low z are almost invariably located in clusters of galaxies. We use the most accurate photometric redshifts available to date, derived by the COSMOS collaboration using photometry with a set of 30 filters, to look for three-dimensional space over-densities around our objects. Three out of the five FRIs in our sample which possess reliable photometric redshifts between z_phot = 1.7 and 2.0 display overdensities that together are statistically significant at the 4-sigma level, compared to field counts, arguing for the presence of rich clusters of galaxies in their Mpc environment. These first results show that the new method for finding high-z clusters we recently proposed, which makes use of low power FRI radio galaxies instead of the more powerful FRII sources often used in the literature to date, is returning very promising candidates.

Frequency responses of streamwise-constant perturbations in channel flows of Oldroyd-B fluids

description: Non-modal amplification of disturbances in streamwise-constant channel flows of Oldroyd-B fluids is studied from an input-output point of view by analyzing the responses of the velocity components to spatio-temporal body forces. These inputs into the governing equations are assumed to be harmonic in the spanwise direction and stochastic in the wall-normal direction and in time. An explicit Reynolds number scaling of frequency responses from different forcing to different velocity components is developed, showing the same $Re$-dependence as in Newtonian fluids. It is found that some of the frequency response components peak at non-zero temporal frequencies. This is in contrast to Newtonian fluids, where peaks are always observed at zero frequency, suggesting that viscoelastic effects introduce additional timescales and promote development of flow patterns with smaller time constants than in Newtonian fluids. The temporal frequencies, corresponding to the peaks in the components of frequency response, decrease with an increase in viscosity ratio (ratio of solvent viscosity to total viscosity) and show maxima for non-zero elasticity number. Our analysis of the Reynolds-Orr equation demonstrates that the energy-exchange term involving the streamwise/wall-normal polymer stress component $τ_{xy}$ and the wall-normal gradient of the streamwise velocity $\partial_y u$ becomes increasingly important relative to the Reynolds stress term as the elasticity number increases, and is thus the main driving force for amplification in flows with strong viscoelastic effects.

description: The bond-percolation properties of the Hanoi networks are analyzed with the renormalization group. Unlike scale-free networks, they are meant to provide an analytically tractable interpolation between finite dimensional, lattice-based models and their mean-field limits. In percolation, the hierarchical small-world bonds in the Hanoi networks impose a new form of order by uniting otherwise disconnected, local clusters. This "patchy" order results in merely a finite probability to obtain a spanning cluster for certain ranges of the bond probability, unlike the usual 0-1 transition found on ordinary lattices. The various networks studied here exhibit a range of phase behaviors, depending on the prevalence of those long-range bonds. Fixed points in general exhibit non-universal behavior.

A strategy for the quantitative analysis of fungal cell walls
Creators: name: Cameron, Donald Stewart
Publisher: name: University of British Columbia
Year: 2011

description: Cultures of Tremella mesenterica grown as haploid yeast-like unicells and Saprolegnia diclina were grown on incompletely defined media and the procedures for isolating cell wall preparations from each, free of cytoplasmic and capsular material, are described. A strategy for quantitative analysis of these cell wall preparations was devised and tested, selecting from the numerous procedures available: extraction and gravimetry for lipids; hydrolysis followed by gas-liquid chromatography for neutral sugars (as trimethyIsiIyI derivatives) and automatic amino acid analysis for amino acids and amino sugars. Problems of degradation as a result of hydrolysis have been considered. The extent to which degradation occurs is difficult to estimate because each constituent polymer is 'contaminated' with the others. This may accelerate degradation, particularly of amino acids. Analytical procedures were reproducible but only 90% of the weight of the cell wall was recovered. The remaining 10% is probably the result of degradation losses that have not been accounted for, and further studies are required to improve the estimation of this error. Even under carefully standardized conditions, cell wall preparations show variable composition. A complete analysis was therefore performed on a single cell wall preparation of each of the two species. Analyses were performed on other cell wall preparations of the' two species and they showed general similarities; the ratios of components were similar, although, for example one preparation, of S. diclina contained more than twice as much total protein as. another. Similar recoveries of constituents suggest that the strategy is appropriate for quantitative analysis. However, alternative methods for lipid analysis that provide more specific information are available and should be adapted for cell wall analysis. Quantitative recovery of uronic acids provides substantial difficulties, and improved methods are required.

description: Eleven-dimensional supergravity admits non-supersymmetric solutions of the form AdS(5)xM(6) where M(6) is a positive Kahler-Einstein space. We show that the necessary and sufficient condition for such solutions to be stable against linearized bosonic supergravity perturbations can be expressed as a condition on the spectrum of the Laplacian acting on (1,1)-forms on M(6). For M(6)=CP(3), this condition is satisfied, although there are scalars saturating the Breitenlohner-Freedman bound. If M(6) is a product S(2)xM(4) (where M(4) is Kahler-Einstein) then there is an instability if M(4) has a continuous isometry. We show that a potential non-perturbative instability due to 5-brane nucleation does not occur. The bosonic Kaluza-Klein spectrum is determined in terms of eigenvalues of operators on M(6).

Pareidolia : a visual inquiry into the perception of ambiguous images
Creators: name: Hodgetts, RJ
Publisher: name: University Of Tasmania
Year: 2023

description: This project explores the creative dynamics of visual perception through the phenomenon of pareidolia. Pareidolia manifests itself in recognisable shapes perceived in random stimuli and is a process which resists both adequate explanation and interpretation. The study explores some of the many cognitive and visual processes involved in the phenomenon, and interprets the findings in a materialistic form. Although pareidolia is often viewed as an illusion or misinterpretation of ambiguous stimuli, I believe it is an innate process which is allied to both imagination and human survival. This study explores the concept that it is a dual reality which brings into question established perceptions of reality. Utilising the medium of painting, I aim to create a body of work which reveals my interpretive response to random stimuli which contain pareidolian cues. The works and observations are a subjective analysis of ambiguous provocations which also bond cognitive and visual percepts to a material platform. The works reflect subconscious interactions with my perceptual set and reveal the vast array of responses which can emerge from seemingly featureless visual stimuli. From the figurative to the abstract, from the decorative to the simplistic, pareidolia evokes endless potential for artistic investigation. The project documents the progression of paintings, from initial interpretation, to the conceptual and visual closure of the percept. Three distinct phases emerge, figurative, ambiguous and abstract/pattern, all seemingly intertwined in degrees of shapeshifting. Within this context, the study examines artists who have utilised numerous aspects of this phenomenon in both subtle and overt guises. Leonardo da Vinci, Giuseppe Arcimboldo, Alexander Cozens, Justinus Kerner and Max Ernst are representative of artists who have pioneered new developments in this genre. In an Australian context, the work of Russell Drysdale and Reinis Zusters exhibit unique aspects of pareidolia which respond to their vision of the Australian landscape.

description: Purpose This investigation was designed to further the development of a treatment for acquired apraxia of speech (AOS), Sound Production Treatment (SPT), by examining the effects of blocked and random practice.
Method A multiple-baseline design across participants and behaviors was used with 6 speakers with chronic AOS and aphasia. Accuracy of production of target sounds in treated and untreated words produced in probe sessions served as the primary dependent variable. Stimulus generalization was also measured to phrase production and sentence completion. Participants received SPT applied with blocked presentation of treatment words (SPT-blocked) and SPT applied with random presentation of treatment words (SPT-random).
Results Increases in accuracy of articulation of target sounds in treated words were observed for all participants for both conditions of treatment. SPT-random appeared to be associated with better maintenance for 2 participants. Generalization to untreated words was positive for all participants for SPT-random and SPT-blocked. Stimulus generalization effects varied across participants and measurement conditions; patterns of generalization did not appear to be associated with treatment condition. Conclusions There may be an advantage for SPT-random for some speakers with AOS. Findings from the nonspeech motor learning literature may not translate directly to the treatment of AOS.

description: In this paper, we study the quantum properties of the three-mode squeezed operator. This operator is constructed from the optical parametric oscillator based on the three concurrent $χ^{(2)}$ nonlinearities. We give a complete treatment for this operator including the symmetric and asymmetric nonlinearities cases. The action of the operator on the number and coherent states are studied in the framework of squeezing, second-order correlation function, Cauchy-Schwartz inequality and single-mode quasiprobability function. The nonclassical effects are remarkable in all these quantities. We show that the nonclassical effects generated by the asymmetric case--for certain values of the system parameters--are greater than those of the symmetric one. This reflects the important role for the asymmetry in the system. Moreover, the system can generate different types of the Schrödinger-cat states.

Measurement and CFD modelling of diesel engine spray dynamics
Creators: name: Ghiji, M
Publisher: name: University Of Tasmania
Year: 2023

description: Engine manufacturers are constantly aiming to reduce exhaust gas emissions by optimizing the fuel injection process. Despite the wide use of injectors, the key physics governing the injection process are not yet fully understood. The primary atomisation process of the liquid fuel jet is initiated in the injector nozzle and the region close to the nozzle exit, influences secondary atomisation and ultimately the entire spray dynamics. Computational Fluid Dynamics (CFD) which is used in the design of fuel injectors is subjected to further developments through the inclusion of research findings. The present work focuses on processes in the nozzle and the first several nozzle diameters after the nozzle exit of a sharp edged single-hole solid cone injector. The aim of this research is to gain further insight into the primary atomisation at different stages of the injection process; the Start Of Injection (SOI); the Quasi-Steady stage; and finally the End Of Injection (EOI). Experiments are conducted using back- and side-lit microscopic imaging techniques within a constant volume high pressure spray chamber. The numerical method is based on the Volume Of Fluid (VOF) phase-fraction interface capturing technique, in an Eulerian framework integrated with Large Eddy Simulation (LES) turbulence modelling. The influences of grid resolution, convection interpolation scheme, temporal integration scheme, compressibility, shock waves, phase changes of the liquid jet, and in-nozzle disturbances on the modelling of jet physics are investigated. The early stage liquid jet leading edge demonstrates an umbrella-shaped structure in the numerical results which is in qualitative agreement with experimental imaging. The existence of vortex before liquid fuel emergence suggests the inclusion of air in the nozzle prior to injection. The development of supercavitation down to the end of the nozzle hole leads to the detachment of the liquid from the nozzle walls, associated with the diminution of boundary layer effects and thus reduced in-nozzle turbulence and increased liquid jet velocity. The numerical and experimental results demonstrate the shock waves occur where the jet velocity at the interface with the surrounding air exceeds the local speed of sound. Analysis of the EOI process shows the mechanism of air ingestion into the nozzle liquid due to the high inertia of liquid jet emerging from the nozzle. Numerical results show not only how a single bubble of chamber gas remaining embedded within the liquid in the nozzle hole, but also show entrainment of air into the sac volume of the injector at the EOI. These results provide further insight into the air ingestion process, an explanation for the presence of gas at the SOP in the experimental images. The existence of large droplets at the EOI is shown, which is potentially a source of unburnt hydrocarbons and detrimental emissions in a real engine.

description: We present weak lensing mass estimates of seven shear-selected galaxy cluster candidates from the Deep Lens Survey. The clusters were previously identified as mass peaks in convergence maps of 8.6 sq. deg of R band imaging, and followed up with X-ray and spectroscopic confirmation, spanning a redshift range 0.19 - 0.68. Most clusters contained multiple X-ray peaks, yielding 17 total mass concentrations. In this paper, we constrain the masses of these X-ray sources with weak lensing, using photometric redshifts from the full set of BVRz' imaging to properly weight background galaxies according to their lensing distance ratios. We fit both NFW and singular isothermal sphere profiles, and find that the results are insensitive to the assumed profile. We also show that the results do not depend significantly on the assumed prior on the position of the mass peak, but that this may become an issue in future larger samples. The inferred velocity dispersions for the extended X-ray sources range from 250-800 km/s, with the exception of one source for which no lensing signal was found. This work further establishes shear selection as a viable technique for finding clusters, but also highlights some unresolved issues such as determination of the mass profile center without biasing the mass estimate, and fully accounting for line-of-sight projections.

description: We study the light scattering properties of random ballistic aggregates constructed in Shen et al. (Paper I). Using the discrete-dipole-approximation, we compute the scattering phase function and linear polarization for random aggregates with various sizes and porosities, and with two different compositions: 100% silicate and 50% silicate-50% graphite. We investigate the dependence of light scattering properties on wavelength, cluster size and porosity using these aggregate models. We find that while the shape of the phase function depends mainly on the size parameter of the aggregates, the linear polarization depends on both the size parameter and the porosity of the aggregates, with increasing degree of polarization as the porosity increases. Contrary to previous studies, we argue that monomer size has negligible effects on the light scattering properties of ballistic aggregates, as long as the constituent monomer is smaller than the incident wavelength up to 2*pi*a_0/lambda\sim 1.6 where a_0 is the monomer radius. Previous claims for such monomer size effects are in fact the combined effects of size parameter and porosity. Finally, we present aggregate models that can reproduce the phase function and polarization of scattered light from the AU Mic debris disk and from cometary dust, including the negative polarization observed for comets at scattering angles 160

description: The development of micropixel gas detectors, capable to image tracks produced in a gas by photoelectrons, makes possible to perform polarimetry of X-ray celestial sources in the focus of grazing incidence X-ray telescopes. HXMT is a mission by the Chinese Space Agency aimed to survey the Hard X-ray Sky with Phoswich detectors, by exploitation of the direct demodulation technique. Since a fraction of the HXMT time will be spent on dedicated pointing of particular sources, it could host, with moderate additional resources a pair of X-ray telescopes, each with a photoelectric X-ray polarimeter (EXP2, Efficient X-ray Photoelectric Polarimeter) in the focal plane. We present the design of the telescopes and the focal plane instrumentation and discuss the performance of this instrument to detect the degree and angle of linear polarization of some representative sources. Notwithstanding the limited resources, the proposed instrument can represent a breakthrough in X-ray Polarimetry.

Assessing the association between trends in a biomarker and risk of event with an application in pediatric HIV/AIDS
Creators: name: Brown, Elizabeth R.
Publisher: name: arXiv
Year: 2009
Subjects: subject: Applications (stat.AP)
subject: FOS: Computer and information sciences

description: We present a new joint longitudinal and survival model aimed at estimating the association between the risk of an event and the change in and history of a biomarker that is repeatedly measured over time. We use cubic B-splines models for the longitudinal component that lend themselves to straight-forward formulations of the slope and integral of the trajectory of the biomarker. The model is applied to data collected in a long term follow-up study of HIV infected infants in Uganda. Estimation is carried out using MCMC methods. We also explore using the deviance information criteria, the conditional predictive ordinate and ROC curves for model selection and evaluation.

description: The tomographic method is employed to investigate the presence of quantum correlations in two classes of parameter-dependent states of two qutrits. The violation of some Bell's inequalities in a wide domain of the parameter space is shown. A comparison between the tomographic approach and a recent method elaborated by Wu, Poulsen and Molmer shows the better adequacy of the former method with respect to the latter one.

description: We present a practical, algebraic method for efficiently calculating the Yukawa couplings of a large class of heterotic compactifications on Calabi-Yau three-folds with non-standard embeddings. Our methodology covers all of, though is not restricted to, the recently classified positive monads over favourable complete intersection Calabi-Yau three-folds. Since the algorithm is based on manipulating polynomials it can be easily implemented on a computer. This makes the automated investigation of Yukawa couplings for large classes of smooth heterotic compactifications a viable possibility.

description: The ecological state of aquatic ecosystems is systematically monitored using various bioindicators in many countries worldwide. In the European Union, freshwater biomonitoring is the central component of the EU Water Framework Directive (WFD, 2000/60/EC) and currently based on morpho-taxonomic methods. DNA metabarcoding is a novel approach to assess the ecological state fast and efficiently based on organismal DNA signatures and thereby support and upscale biomonitoring. However, compliance of metabarcoding with existing morpho-taxonomic methods must be ensured prior to official implementation. Thus, this study, co-designed by research institutions and environmental agencies, explored necessary key parameters and performed method intercalibration for the implementation of metabarcoding into WFD assessments of running waters. We focussed on benthic invertebrates as the most commonly used bioindicators. We analysed 170 invertebrate samples collected as part of the German federal state WFD routine stream biomonitoring, first via microscopic determination and then using metabarcoding. Our goals were to quantify overlap in i) taxonomic composition and ii) ecological status derived with both methods. For this purpose, we established data harmonisation measures to integrate invertebrate metabarcoding data into the official national WFD classification modules considering abundance and presence/absence data. Our results revealed a high (ca. 70 %) overlap of bioindicator taxa found with both methods. Metabarcoding identified significantly more small invertebrate taxa and detected similar proportions of the important bioindicator ‘EPT’ taxa (mayflies, stoneflies, caddisflies). Despite deviations in some detected bioindicator taxa, the derived ecological status classes were highly correlated between methods, particularly after intercalibration (R2 = 0.74, Spearman rho = 0.86). Regardless of whether we used abundance or presence/absence data, the resulting stream type classifications showed strong agreement. Thus, our study not only demonstrates the consistency of the methods for the stream types analysed but is also the first to operationalise a path to integration of metabarcoding data into the WFD assessment modules based on formal intercalibration guidelines.
