description: We numerically solve the Klein-Gordon equation at second order in cosmological perturbation theory in closed form for a single scalar field, describing the method employed in detail. We use the slow-roll version of the second order source term and argue that our method is extendable to the full equation. We consider two standard single field models and find that the results agree with previous calculations using analytic methods, where comparison is possible. Our procedure allows the evolution of second order perturbations in general and the calculation of the non-linearity parameter f_NL to be examined in cases where there is no analytical solution available.

description: In this Letter we show how the nonlinear evolution of a resonant triad depends on the special combination of the modes' phases chosen according to the resonance conditions. This phase combination is called dynamical phase. Its evolution is studied for two integrable cases: a triad and a cluster formed by two connected triads, using a numerical method which is fully validated by monitoring the conserved quantities known analytically. We show that dynamical phases, usually regarded as equal to zero or constants, play a substantial role in the dynamics of the clusters. Indeed, some effects are (i) to diminish the period of energy exchange $τ$ within a cluster by 20$%$ and more; (ii) to diminish, at time scale $τ$, the variability of wave energies by 25$%$ and more; (iii) to generate a new time scale, $T >> τ$, in which we observe considerable energy exchange within a cluster, as well as a periodic behaviour (with period $T$) in the variability of modes' energies. These findings can be applied, for example, to the control of energy input, exchange and output in Tokamaks; for explanation of some experimental results; to guide and improve the performance of experiments; to interpret the results of numerical simulations, etc.

description: Frictional drag is a major parameter that influences the efficiency of many engineering applications involving a relative motion between a solid surface and a turbulent fluid like the flow of air over an aircraft, water over a ship hull and flow of oil through pipelines. A thin layer of fluid near the bounding surface is called the boundary layer. The turbulence activity in the boundary layer is responsible for the majority of the frictional drag. An in-depth understanding of the mechanism of skin friction generation in wall-bounded turbulent flows is essential for the development of better flow control techniques and drag reduction devices. In this study, direct numerical simulations of three turbulent boundary layer cases with different streamwise pressure gradients are considered to investigate the various factors and coherent structures that influence the skin friction.
Energy-efficient large medium-speed catamarans : hull form design by full-scale CFD simulations
Creators: name: Haase, M
Publisher: name: University Of Tasmania
Year: 2023

description: Large medium-speed catamarans are currently under development as a new class of vessel for economically efficient and more environmentally sustainable fast sea transportation. Their design is based on current high-speed catamarans, to adopt advantages such as large deck areas and low wave-making resistance, but they will operate at lower speeds and carry a higher deadweight to obtain higher transport efficiency. They operate at speeds around the main drag hump, where the wave-making drag coefficient is at its maximum. Hence this speed range is usually avoided by boat designers no precise guidelines for hull form design of large medium-speed catamarans are present to operate efficiently in this generally unfavourable speed spectrum. Literature has been surveyed to derive hull form parameters that provide low drag for monohulls and catamaran vessels. Based on these findings a hull form family was developed with demihull slenderness ratios ranging from 9 to 15 and the hydrodynamic performance was evaluated at Froude numbers from 0.25 up to 0.49 to derive design parameters with the lowest drag and highest transport efficiency. These parameters corresponds to vessel sizes from 110 m to 190 m and speeds of 16 to 41 knots. A novel CFD-based approach has been developed to provide more accuracy to the final drag prediction at full scale. It was verified using results of model scale experiments of a 98 m and a 130 m catamaran and validated with results obtained from sea trial measurements, in deep as well as in shallow water. Furthermore, its capability to replicate the flow past a typical deep partially ventilated transom has been investigated using model scale experiments. The key advantage of this method is that the same computational mesh can be used for model-scale verification and full-scale predictions. The computational full-scale simulation approach was found to be capable of predicting the drag force within 5% of results derived from full-scale measurements and extrapolated model test data. In addition it has been shown to correctly predict steady and unsteady shallow water effects. Also the ventilation process of the transom stern has been experimentally validated and the ow feature in the stagnant zone past the partially ventilated transom was identified as a non-shedding squashed horseshoe vortex. The lowest drag can be achieved for catamarans with demihull slenderness ratios of 11 to 13 and hulls of 150 m in length provided highest transport efficiency for speeds of 20 to 35 knots at a light displacement, and 170 m and 190 m for a medium and a heavy displacement respectively. Finally, when comparing the results to contemporary large and fast catamarans carrying equivalent deadweight and travelling at the same speed, fuel savings up to 40% can be achieved if a hull of 150 m instead of 110 m length is used. This demonstrates that large medium catamarans have the potential to be a fuel-efficient alternative for a successful future of fast sea transportation.

description: Previous high resolution cosmological simulations predict the first stars to appear in the early universe to be very massive and to form in isolation. Here we discuss a cosmological simulation in which the central 50 solar mass clump breaks up into two cores, having a mass ratio of two to one, with one fragment collapsing to densities of 10^{-8} g/cc. The second fragment, at a distance of 800 astronomical units, is also optically thick to its own cooling radiation from molecular hydrogen lines, but is still able to cool via collision-induced emission. The two dense peaks will continue to accrete from the surrounding cold gas reservoir over a period of 10^5 years and will likely form a binary star system.

description: We investigate the young stellar population in and near the cometary globule Ori,I-2. The analysis is based on deep Nordic Optical Telescope R-band and H-alpha images, JCMT SCUBA 450 and 850 micron images combined with near-infrared 2MASS photometry and mid-infrared archival Spitzer images obtained with the IRAC (3.6, 4.5, 5.8 and 8 micron), and MIPS (24 and 70 micron) instruments. We identify a total of 125 sources within the 5'x5' region imaged by IRAC. Of these sources 87 are detected in the R-band image and 51 are detected in the 2MASS survey. The detailed physical properties of the sources are explored using a combination of near/mid-infrared color-color diagrams, greybody fitting of SEDs and an online SED fitting tool that uses a library of 2D radiation transfer based accretion models of young stellar objects with disks. Ori I-2 shows clear evidence of triggered star formation with four young low luminosity pre-main sequence stars embedded in the globule. At least two, possibly as many as four, additional low-mass PMS objects, were discovered in the field which are probably part of the young sigma-Orionis cluster. Among the PMS stars which have formed in the globule, MIR-54 is a young, deeply embedded Class 0/I object, MIR-51 and 52 are young Class II sources, while MIR-89 is a more evolved, heavily extincted Class II object with its apparent colors mimicking a Class 0/I object. The Class II source, MIR-52, which is strong a H-alpha emission line star appears to drive an outflow approximately aligned with the outflow from MIR-54, and because of the proximity of the two outflows, either star could contribute. MIR-89 appears to excite a low excitation HH object, HH 992, discovered for the first time in this study.

Isolation of anaerobic cellulolytic thermophiles and production and purification of the cellulase from Clostridium thermocellulaseum M-7
Creators: name: Lee, Byong Hoon
Publisher: name: University of British Columbia
Year: 2011

description: An enrichment procedure led to the isolation, by the cellulose roll tube method, of a number of actively cellulolytic anaerobic thermophilic bacteria. Two isolates were terminally sporing rods and were tentatively identified as Clostridium thermocellulaseum (Enebo, 1951). Strain M-7 (0.6 μm x 4.0 μm) from manure grew optimally at 58°C to 63°C, pH 6.0 to 6.5 and did not require organic nitrogen. Strain C-19 (0.3 μm x 4.5 μm) from compost was similar but grew optimally at 50°C to 68°C, pH 7.5. Both utilized cellobiose and a wide range of other sugars. Strain C-19 did not utilize glucose, raffinose and inositol but did use inulin. The mean generation times in a rich nutrient medium containing cellobiose were 35 min for strain M-7 and 25 min for strain C-19. Strain M-7 had a mean generation time of 2 hr when grown on cellulose. Yeast extract (0.5%) stimulated growth and cellulase production by strain M-7 but was inhibitory at higher concentrations. Other organic nitrogen sources acted similarly. Cellulose at 1.0% gave maximum cellulase production after 72 hr incubation of strain M-7. Higher concentrations of cellulose were not completely degraded in 72 hr. Strain M-7 did not produce cellulase when grown on any carbon source other than cellulose substrates. The addition of cellobiose (0.3%) and glucose (0.4%) prevented cellulose hydrolysis in cellulose medium. This may have been repression of synthesis but cellulase was inhibited by both sugars. Both C₁, cellulase (degrades native cellulose) and Cx cellulase (β-1,4-glucanase) activities in strain M-7 cultures were assayed by measuring the liberation of reducing sugars, using dinitrosalicylic acid. Both activities had optima at pH 6.5 and 67°C. Cx cellulase could conveniently be assayed by a new automated procedure. Strain M-7 was very actively cellulolytic when compared to previously microbial species. The 48 hr culture contained Cx activity (56 μg glucose/min/ml from carboxymethyl cellulose) and C₁ activity (8 μg glucose/min/ml from cotton fibres); the ratio of C₁,:Cx was 1:7. The cellulase(s) from strain M-7 were extra-cellular, produced during exponential growth but were not free in the growth medium until 50% of the cellulose was hydrolyzed. Glucose and cellobiose were the only soluble products liberated by the cellulase from cellulose. ZnCl₂ precipitation appeared to be a good method for the concentration of cellulase activity but subsequent purification was not successful. Isoelectric focusing indicated the presence of four Cx cellulases (pI 4.5, 6.3, 6.8, and 8.7). DEAE-Sephadex chromatography indicated three Cx components. It is concluded that C. thermocellulaseum M-7 produces cellulase(s) capable of rapidly hydrolyzing native cellulose. The rapid production and high activity of cellulases from this organism strongly support the basic premise that increased hydrolysis of cellulose is possible at elevated temperature.

The influence of late-life university education on age-related cognitive decline and cognitive reserve : The Tasmanian Healthy Brain Project
Creators: name: Thow, ME
Publisher: name: University Of Tasmania
Year: 2023

description: Background: A strong link between education and cognitive performance suggests that a period of education in later-life could reduce age-related cognitive decline (ARCD) and risk for Alzheimer's disease (AD). The aim of this thesis was to examine the effect of late-life education on cognitive reserve (CR), cognitive functioning; and the potential influence of genetic factors on any relationship. Method: A sample of 459 participants aged 50-79 years (M = 60.24, SD = 6.75) enrolled in the first four years of the THBP, provided salivary samples for genetic analysis and completed comprehensive annual cognitive assessments. Within this sample, an intervention group (n = 359) who undertook a minimum of 12 months part-time university level education were compared with a control reference group (n = 100). Results: Growth Mixture Modelling (GMM) revealed that while 92.5% of the intervention group displayed an increase in CR, only 55.6% of the control group displayed an increase. Further, the intervention group displayed a significant increase in language processing capacity but no significant change in episodic memory, working memory or executive function. There was no influence of genetic factors (APOE ˜í¬µ4 or BDNF Val66Met) on cognitive function over time or on intervention response. Conclusions: Attending university improved CR and triggered a commensurate improvement in crystallised cognitive function (language processing capacity) but not fluid cognitive functions (episodic memory, working memory or executive function). These results indicate that encouraging mental activity in later-life may be a viable means to reduce ARCD and potentially delay the onset of AD.
Learning to be the mistress : convict transportation, domestic service and family structure in 19th century Australia and America
Creators: name: Hodgson, AM
Publisher: name: University Of Tasmania
Year: 2023

description: Many thousands of women were transported to Britain's colony Van Diemen's Land (Tasmania) between 1803, when the colony was founded, and 1853 when transportation ceased. Some died at sea; some endured colonial lives of struggle, poverty or crime; many failed to form families and lived out their years without kith and kin to support them. Eliza Williams was one who prospered. Williams achieved security, status and wealth. Her legacy of letters allows a new assessment of the life, aspirations and opportunities of convict women. Williams, a young Irish woman convicted of theft from her London workplace, arrived in Hobart Town in 1852. By 1862 she was living in Detroit, married to Irishman George Hanley, and with her first child toddling at her feet. In the space of a decade she had travelled from Britain to Australia and back, then across the Atlantic to New York and on to Detroit. Three decades later she was firmly established in Detroit society, living in its premiere Yankee suburb. She had departed Tasmania with skills, knowledge and determination. Hers is a story of transformation: from servant to mistress. Williams served her sentence in the house of John Leake and his family. Leake was master to a household and estate workforce that was predominantly drawn from convict ranks. The Rosedale estate was an open prison. The way convictism shaped the lives of both master and worker is fundamental to this thesis. The original contribution of the research is an analysis of the impact on domestic life of the colonial convict experience. This is achieved by close examination of the lives of two nineteenth-century women, one a transported convict and the other her colonial employer. The thesis also explores how daily life in the private home was conducted and maintained. The research has exposed a neglected archive to detailed examination. The Leake Papers held by the University of Tasmania provided the means to give voice to a diverse community who inhabited a colonial estate and hitherto were silent in the record.

description: The mechanism of electron pairing in high-temperature superconductors is still the subject of intense debate. Here, we provide direct evidence of the role of structural dynamics, with selective atomic motions (buckling of copper-oxygen planes), in the anisotropic electronlattice coupling. The transient structures were determined using time-resolved electron diffraction, following carrier excitation with polarized femtosecond heating pulses, and examined for different dopings and temperatures. The deformation amplitude reaches 0.5 % of the c-axis value of 30 A when the light polarization is in the direction of the copper-oxygen bond, but its decay slows down at 45 degrees. These findings suggest a selective dynamical lattice involvement with the anisotropic electron-phonon coupling being on a time scale (1 to 3.5 ps depending on direction) of the same order of magnitude as that of the spin exchange of electron pairing in the high-temperature superconducting phase.

description: A simulation model is presented, comprising elastic spheres with a short range attraction. Besides conservative forces, radial- and shear friction, and radial noise are added. The model can be used to simulate colloids, granular solids and powders, and the parameters may be related to experimental systems via the range of attraction and the adhesion energy. The model shares the simplicity and speed of Dissipative Particle Dynamics (DPD), yet the predictions are rather non-trivial. We demonstrate that the model predicts the correct scaling relations for fracture of granular solids, and we present a schematic phase diagram. This shows liquid-vapor coexistence for sufficiently large interaction range, with a surface tension that follows Ising criticality. For smaller interaction range only solid-vapor coexistence is found, but for very small attractive interaction range stable liquid-vapor coexistence reappears due to pathological stability of the solid phase. At very low temperature the model forms a glassy state.

description: The Conventions of the Rights of the Child aims to facilitate children’s provision, protection, and participation to enhance their lives. Facilitating children’s participation involves providing adequate information and giving children opportunities to share their views in decision-making processes. In Ireland, children’s participation is supported by the national participation strategy 2015-2020 which has recently been followed-up by the Participation Implementation Framework. This includes the expectation that all children, including those with disabilities should participate in (re)design processes of public playspaces in their communities. This poster presents on phase one of a PhD study that aims to explore how children’s participation is incorporated in guidelines for (re)designing public playspace. A scoping review methodology is being used to identify guidelines on (re)designing public playspaces. Data analysis involves a mapping and extracting process between frameworks of children’s participation and guidelines, tools and policies on (re)design public playspaces. Occupational therapists working in and with the local community are considered as important stakeholders in enabling children with disabilities to share their views in matters that affect, for example in creating play opportunities in the neighbourhood and contributing to social inclusion.

description: All prior work on measuring the spins of stellar-mass black holes via the X-ray continuum-fitting method has relied on the use of weakly-Comptonized spectra obtained in the thermal dominant state. Using a self-consistent Comptonization model, we show that one can analyze spectra that exhibit strong power-law components and obtain values of the inner disk radius, and hence spin, that are consistent with those obtained in the thermal dominant state. Specifically, we analyze many RXTE spectra of two black hole transients, H1743-322 and XTE J1550-564, and we demonstrate that the radius of the inner edge of the accretion disk remains constant to within a few percent as the strength of the Comptonized component increases by an order of magnitude, i.e., as the fraction of the thermal seed photons that are scattered approaches 25%. We conclude that the continuum-fitting method can be applied to a much wider body of data than previously thought possible, and to sources that have never been observed to enter the thermal dominant state (e.g., Cyg X-1).

Some unpublished letters from Thomas Henry Hall Caine to Dante Gabriel Rossetti (July 1879 - July 1881)
Creators: name: Dolman, Florence Janet Lucy Caple
Publisher: name: University of British Columbia
Year: 2011

description: This thesis is a selected edition of thirty-six unpublished letters and fragments from Thomas Henry Hall Caine to Dante Gabriel Rossetti with an introduction and explanatory notes. The letters have been chosen to illustrate Caine's typical interests and concerns as these appear in the body of eighty-six unpublished letters and fragments contained in the Angeli Papers in Special Collections at the University of British Columbia Library. Although the letters are far from being masterpieces of epistolary art, they are of historical interest as a chronicle of the friendship which was initiated by letter. The introduction provides a background for the letters, using, in so far as possible, unpublished contemporaneous material from the Angeli and Penkill Papers. Hall Caine knew Rossetti for less than three years; for two of those years the friendship was conducted almost exclusively by letter, but for the last ten months of Rossetti1s life they lived together. The friendship began when Caine published a eulogistic article on Rossetti's poetry, and sent a copy to him. Caine was then an eager, ambitious, and very naive twenty-six year old Liverpudlian; Rossetti, a known painter and poet of fifty-one, was lonely, frightened, filled with morbid phantasies and a chloral hydrate addict. He was virtually a recluse in his gloomy London house, but Caine's letters revived his interest in literary criticism and during the last years of his life Rossetti taught Caine about literature. His "pupil's" interest and energy also helped to inspire Rossetti on his own behalf, for in 1881 he published a revised edition of Poems and a new book, Ballads and Sonnets. Very shortly after Rossetti*s death, Caine published his Recollections of Dante Gabriel Rossetti (1882), a biography of his friend which included some seventy-five fragments of the "nearly two hundred letters" he had received from Rossetti. In 1908 Caine included a large section on Rossetti in My Life, and in 1928 he produced a considerably altered version of his first biography. Caine became a prolific and popular novelist and playwright, was knighted for his war effort, and made a Companion of Honour "in recognition of his distinction in literature," but in spite of his successes, skepticism remains concerning his reliability as Rossetti's biographer. The doubts must have sprung from Caine's character—he had a romantic sensibility, a flair for seeing the simplest events dramatically, and a distinct taste for self-aggrandizement. However, although contemporaneous materials indicate that he inspired a certain wariness among Rossetti’s intimates, there are no concrete reasons to doubt his veracity in matters of fact.

description: We study the limits of communication efficiency for function computation in collocated networks within the framework of multi-terminal block source coding theory. With the goal of computing a desired function of sources at a sink, nodes interact with each other through a sequence of error-free, network-wide broadcasts of finite-rate messages. For any function of independent sources, we derive a computable characterization of the set of all feasible message coding rates - the rate region - in terms of single-letter information measures. We show that when computing symmetric functions of binary sources, the sink will inevitably learn certain additional information which is not demanded in computing the function. This conceptual understanding leads to new improved bounds for the minimum sum-rate. The new bounds are shown to be orderwise better than those based on cut-sets as the network scales. The scaling law of the minimum sum-rate is explored for different classes of symmetric functions and source parameters.

description: In this study, we have developed two facile spectroscopic methods for quantifying oxybutynin (OBT) hydrochloride in its pure form and tablets using design of experiments (DOEs). The spectroscopic methods depended on the ion-pair complex formation between the tertiary amino group in the drug and eosin in 0.2 M acetate buffer of pH 4. Method I involves spectrophotometric measurement of the absorbance of the developed complex at 550 nm and showed linearity through 1.0–10.0 µgml−1. Method II involves spectrofluorometric measurement of the quenching influence of OBT on the native fluorescence of eosin (λ excitation/λ emission of 304/548 nm) and showed linearity through 1.0–6.0 µg ml−1. Critical parameters were identified through preliminary trials and optimized using the DOE. Additionally, the quenching mechanism was investigated and the pathway of the reaction was postulated. The fluorescence quenching constant and thermodynamic parameters were explored using the Stern–Volmer plot and Van't Hoff graph, respectively. Assessments conducted via Analytical ecoscale revealed the ‘excellent-greenness’ of the methodology. The two methods have the potentials of being green and fast compared with other reported methods.

Wu's spiritual autobiography _Beyond East and West_ was published in 1951, it became an instant Catholic best seller and was compared to Thomas Merton's _The Seven Storey Mountain_, which had appeared four years earlier. It was also hailed as the new Confession of St. Augustine for its moving description of Wu's conversion in 1937 and early years as a Catholic. This new edition, including a foreward written by Wu's son John Wu, Jr., makes this profoundly beautiful book by one of the most influential Chinese lay Catholic intellectuals of the twentieth century available for a new generation of readers hungry for spiritual sustenance.\u000a\u000a_Beyond East and West_ recounts the story of Wu's early life in Ningpo, China, his family and friendships, education and law career, drafting of the constitution of the Republic of China, translation of the Bible into classical Chinese in collaboration with Chinese president Chiang Kai-Shek, and his role as China's delegate to the Holy See. In passages of arresting beauty, the book reveals the development of his thought and the progress of his growth toward love of God, arriving through experience at the conclusion that the wisdom in all of China's traditions, especially Confucian thought, Taoism, and Buddhism, point to universal truths that come from, and are fulfilled in, Christ.\u000a\u000aIn _Beyond East and West_, Wu develops a synthesis between Catholicism and the ancient culture of the Orient. A sublime expression of faith, here is a book for anyone who seeks the peace of the spirit, a memorable book whose ideas will linger long after its pages are closed.
New WZW D-branes from the algebra of Wilson loop operators
Creators: name: Monnier, Samuel
Publisher: name: arXiv

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We investigate the algebra generated by the topological Wilson loop operators in WZW models. Wilson loops describe the nontrivial fixed points of the boundary renormalization group flows triggered by Kondo perturbations. Their enveloping algebra therefore encodes all the fixed points which can be reached by sequences of Kondo flows. This algebra is easily described in the case of SU(2), but displays a very rich structure for higher rank groups. In the latter case, its action on known D-branes creates a profusion of new and generically non-rational D-branes. We describe their symmetries and the geometry of their worldvolumes. We briefly explain how to extend these results to coset models.

description: In this study, we have developed two facile spectroscopic methods for quantifying oxybutynin (OBT) hydrochloride in its pure form and tablets using design of experiments (DOEs). The spectroscopic methods depended on the ion-pair complex formation between the tertiary amino group in the drug and eosin in 0.2 M acetate buffer of pH 4. Method I involves spectrophotometric measurement of the absorbance of the developed complex at 550 nm and showed linearity through 1.0–10.0 µgml−1. Method II involves spectrofluorometric measurement of the quenching influence of OBT on the native fluorescence of eosin (λ excitation/λ emission of 304/548 nm) and showed linearity through 1.0–6.0 µg ml−1. Critical parameters were identified through preliminary trials and optimized using the DOE. Additionally, the quenching mechanism was investigated and the pathway of the reaction was postulated. The fluorescence quenching constant and thermodynamic parameters were explored using the Stern–Volmer plot and Van't Hoff graph, respectively. Assessments conducted via Analytical ecoscale revealed the ‘excellent-greenness’ of the methodology. The two methods have the potentials of being green and fast compared with other reported methods.
Facing up to a new way of coping : development and psychometric evaluation of a scale to measure engagement in coping strategies facilitated by Facebook
Creators: name: Walker, CS
Publisher: name: University Of Tasmania

description: The increasing prominence of social networking site (SNS) use has led to the identification that people may use such sites to cope with stress. However, to date, no measure has been developed to assess coping in a SNS context. This study aimed to develop a scale to measure engagement in coping strategies facilitated by Facebook and to evaluate its psychometric properties. Participants (N=315) were Facebook users who completed an online questionnaire consisting of 48 items depicting ways of coping via Facebook and additional measures for validity evaluation. Exploratory factor analysis revealed eight Facebook-facilitated coping strategies: Cognitive Coping, Organisation, Spiritual Coping, Information Seeking, Social Support Seeking, Connecting, Disengagement and Venting. Internal consistency, temporal reliability and discriminant validity of the scale were good. Evidence for the scale's convergent validity was mixed. Whilst maladaptive strategies correlated appropriately with other variables, some adaptive strategies did not. Although preliminary, findings suggested that coping via Facebook may have different implications for psychological wellbeing than offline coping. Specifically, Facebook-facilitated coping may encourage disengagement from a stressor, or may not meet the needs of stressed individuals. This study indicates that Facebook facilitates coping, highlighting that coping research, theory and intervention should consider how individuals cope through this medium.
Efficient cosmic ray acceleration, hydrodynamics, and Self-consistent Thermal X-ray Emission applied to SNR RX J1713.7-3946

description: We model the broad-band emission from SNR RX J1713.7-3946 including, for the first time, a consistent calculation of thermal X-ray emission together with non-thermal emission in a nonlinear diffusive shock acceleration (DSA) model. Our model tracks the evolution of the SNR including the plasma ionization state between the forward shock and the contact discontinuity. We use a plasma emissivity code to predict the thermal X-ray emission spectrum assuming the initially cold electrons are heated either by Coulomb collisions with the shock heated protons (the slowest possible heating), or come into instant equilibration with the protons. For either electron heating model, electrons reach >10^7 K rapidly and the X-ray line emission near 1 keV is more than 10 times as luminous as the underlying thermal bremsstrahlung continuum. Since recent Suzaku observations show no detectable line emission, this places strong constraints on the unshocked ambient medium density and on the relativistic electron to proton ratio. For the uniform circumstellar medium (CSM) models we consider, the low densities and high relativistic electron to proton ratios required to match the Suzaku X-ray observations definitively rule out pion-decay as the emission process producing GeV-TeV photons. We show that leptonic models, where inverse-Compton scattering against the cosmic background radiation dominates the GeV-TeV emission, produce better fits to the broad-band thermal and non-thermal observations in a uniform CSM.

Can Component/Service-Based Systems Be Proved Correct?
Creators: name: Attiogbe, Christian
Publisher: name: arXiv

Subjects: subject: Software Engineering (cs.SE)

description: Component-oriented and service-oriented approaches have gained a strong enthusiasm in industries and academia with a particular interest for service-oriented approaches. A component is a software entity with given functionalities, made available by a provider, and used to build other application within which it is integrated. The service concept and its use in web-based application development have a huge impact on reuse practices. Accordingly a considerable part of software architectures is influenced; these architectures are moving towards service-oriented architectures. Therefore applications (re)use services that are available elsewhere and many applications interact, without knowing each other, using services available via service servers and their published interfaces and functionalities. Industries propose, through various consortium, languages, technologies and standards. More academic works are also undertaken concerning semantics and formalisation of components and service-based systems. We consider here both streams of works in order to raise research concerns that will help in building quality software. Are there new challenging problems with respect to service-based software construction? Besides, what are the links and the advances compared to distributed systems?

Is shared care indicated or contraindicated following parental separation?
Creators: name: Turner, CM

description: There is currently a multitude of research relating to shared care and its effect on a child's psychosocial wellbeing following parental separation. However, there is no clear consensus in the literature about what custody arrangement is best for the child following parental separation, especially when there is inter-parental conflict. This systematic literature review aimed to provide a synthesis of the current literature surrounding shared care following separation. The review aimed to ascertain when shared care is indicated or contraindicated in families with children under the age of 12, across both conflict and no conflict families. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA; Moher, Liberati, Tetzlaff, & Altman, 2009) guidelines were implemented for this systematic literature review, with data being extracted from a total of 24 included studies. Of these studies, 18 indicated that shared care was no worse for children's wellbeing than sole custody arrangements. Furthermore, it appears that it is not the care arrangement itself that affects child wellbeing, but a number of other positive and negative factors. These factors have been discussed at length with recommendations being provided for practitioners working in psychology, family therapy and family law.
