description: Στην παρούσα διπλωματική εργασία παρουσιάζεται μια συγκριτική αξιολόγηση πειραματικών μετρήσεων των βασικών χαρακτηριστικών των θαλάσσιων κυμάτων στην περιοχή των Σφακίων.
 Η διεξαγωγή του πειράματος έγινε δυνατή με τη χρήση ειδικής μετρητικής διάταξης η οποία τοποθετήθηκε ανοιχτά του λιμανιού των Σφακίων για  χρονικό διάστημα δύο ετών. Παράλληλα συλλέχθηκαν πληροφορίες και δεδομένα από μετεωρολογικές εκτιμήσεις για το ύψος, τη συχνότητα και τη διεύθυνση των κυμάτων την ίδια χρονική περίοδο.
Στόχος της εργασίας είναι η συλλογή των πειραματικών δεδομένων και η σύγκριση τους με εκτιμήσεις μετεωρολογικών υπολογιστικών μοντέλων. Παρατηρείται, επίσης, η μεταβολή των κυματικών φαινομένων με την πάροδο του χρόνου και την αλλαγή των εποχών και σημειώνονται σημαντικά κυματικά συμβάντα.
Από την μελέτη των μετεωρολογικών εκτιμήσεων των βασικών κυματικών μεγεθών της ίδιας χρονικής περιόδου υποδεικνύεται σημαντική συνάφεια σε σχέση με τα πειραματικά δεδομένα.
Συμπερασματικά, τα αποτελέσματα θα μπορούσαν να χρησιμοποιηθούν για καλύτερη εποπτεία των κυματικών συνθηκών στην περιοχή των Σφακίων τόσο για σκοπούς ναυσιπλοΐας όσο και για κατασκευαστικούς σκοπούς στη διαμόρφωση της ακτής.

description: In the present diploma thesis, a comparative study of experimental measurements of the primary characteristics of sea waves in the area of Sfakia, Crete is presented.
The conduct of the experiment was made possible by the use of a special measuring device, which was located off the port of Sfakia for a total 2 years period of time. Meanwhile, information and data were selected from meteorological estimates of the wave height, frequency and direction at the same time period.
The purpose of this study is the collection of the experimental data and their comparison with the estimates of the meteorological computational models of wave distributions. In addition, the variation/alteration of the wave events during time is observed as well as the variations that occur on different seasons, and significant wave events are noted.

description: We investigate Gevrey order and 1-summability properties of the formal solution of a general heat equation in two variables. In particular, we give necessary and sufficient conditions for the 1-summability of the solution in a given direction. When restricted to the case of constants coefficients, these conditions coincide with those given by D.A. Lutz, M. Miyake, R. Schaefke in a 1999 article, and we thus provide a new proof of their result.

We note that these solutions all have single horizons. These black holes are very similar to each other when studying their thermodynamics. It is shown that a second order phase transition is unlikely possible to occur between $z=3,2$ Lifshitz black holes and $z=1$ Hořava black hole.

The Sentient Body: An exploration of the body's intimate connection to the environment.
Creators: name: Morrison, A
Publisher: name: University Of Tasmania
Year: 2023

description: This project investigates methodologies within the practice of oil painting in order to conceptualise perceptions about the intimate connection between the body and the environment. Today the notion of the integrity of the body as complete and separate is actively fostered by the virtual, which delivers knowledge without the smell and touch of realty. Increasingly insulated from the actual experiences of nature, our biological selves are nonetheless in a state of constant material exchange with the environment. Beyond this functionality, there are those who cultivate a deeper sensory connection with the land. They regard themselves as being at one with the environment and sense within their bodies the rhythms and pulse of the cosmos. It is these internal indicators, felt rather than seen, which form the subject of this project and the investigation has sought the means through painting to successfully conceptualise these feelings of connection. The issue of visually representing sensory responses which do not manifest themselves in pragmatic vision requires the invention of new and effective signifiers. Various methods based upon the fluid applications of oil on canvas have been investigated. Of course visual language cannot be expected to function completely outside the field of metaphor. Here the segments of the process, the actions of painter and paint, form the metaphors for flow and rhythm, and for the bindings which wrap the body into its surroundings. Throughout the project, the subjects of each painting have been the feelings referenced within my own bodily experience. Every work represents a new exploration of the metaphoric process yet, in terms of the investigation, each is an echo of the last and a foretaste of the next. The specific thematic connection of the body and the Environment lifts the project clear of the wider evocative intent present in aspects of the Abstract Expressionist movement, although both similarities and dissimilarities with painterly processes employed by artists such as Helen Frankenthaler and Morris Louis are recognised. The precursors within the thematic of this project are particular works by the artists Helen Chadwick, Ana Mendieta, Mona Hatoum, Terry Winters, Georgia O'Keeffe, Moira Dryer and Ian McKeever.
A study of the petrology and petrophysics of the Black Swan Komatiite, Eastern Goldfields, Western Australia
Creators: name: Italiano, P
Publisher: name: University Of Tasmania
Year: 2023

description: The Black Swan Project, situated some 43 km south of northeast of Kalgoorlie in Western Australia, formed a case study for an assessment of the petrophysical properties of the Black Swan Succession. The Succession hosts a number of discrete magmatic nickel sulphide bodies and associated disseminated mineralization. The study was undertaken with the aim of establishing possible vectors to ore within the project area and potentially elsewhere in the Yilgam Craton. Komatiite flows that host mineralization were examined using a proprietary downhole logging system, OMS~LOGG, which recorded magnetic susceptibility, inductive conductivity, resistivity, natural gamma and gamma-gamma readings on selected diamond drill core samples sourced from both trough and flanking channel environments. Hand-held magnetic susceptibility, specific gravity and conductivity readings were taken from both ore-grade material and host rock lithologies, and a number of representative drillcore samples described in terms of mineralogy, geology and geomechanical data. This information was then used to relate the geophysical properties to individual lithological units. However, establishing such relationships proved difficult, as the variable metamorphic influences within the Black Swan Succession have resulted in wide ranging and inhomogeneous mineralogical assemblages, with complex distribution and composition of magnetic oxide minerals. In general, potentially mineralised trough environments were characterized by high conductivity and a higher density. Carbonate was the most abundant mineral in this environment. Conversely, the channel flanks had lower conductivities, and lower density readings, while chlorite was the primary mineral constituent. Susceptibility readings returned similar ranges in both environments, indicating the technique could not be used as a discriminator. No correlation was noted between manual estimations of magnetite content and magnetic susceptibility or between manual estimates of opaque mineral percentages and magnetic susceptibility. A weak inverse linear relationship was noted between the percentage of opaque material and the gamma-gamma readings in downhole logs.

Nonlinear pair production in scattering of photons on ultra-short laser pulses at high energy
Creators: name: Tuchin, Kirill
Publisher: name: arXiv
Year: 2009
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We consider scattering of a photon on a short intense laser pulse at high energy. We argue that for ultra-short laser pulses the interaction is coherent over the entire length of the pulse. At low pulse intensity $I$ the total cross section for electron-positron pair production is proportional to $I$. However, at pulse intensities higher than the characteristic value $I_s$, the total cross section saturates -- it becomes proportional to the logarithm of intensity. This nonlinear effect is due to multi-photon interactions. We derive the total cross section for pair production at high energies by resuming the multi-photon amplitudes to all orders in intensity. We calculate the saturation intensity $I_s$ and show that it is significantly lower than the Schwinger's critical value. We discuss possible experimental tests.

The Geochemistry and textures of the Grevillea Gossan, Northwest Queensland
Creators: name: Hann, Veryan
Publisher: name: University Of Tasmania
Year: 2023

description: The Grevillea deposit is a newly discovered Pb-Zn-Ag stratabound sediment-hosted deposit in the Lawn Hill Region of NNW Queensland. It lies in part of the Mount Isa Inlier which has been described as one of the richest mineral provinces in the world. The study undertook varied geochemical analyses for determining element variations and the relationships, and elemental partitions in the regolith units. It was found that TI, Pb, Si, Fe are surface indicators of mineralisation for the Grevillea deposit. Two types of rock units dominated the regolith, which overlies the massive pyrite zone: the jarosite limonites and the hematite limonites, and both act as sponges for metals derived from the ore. The jarosite types in the area are likely plumbojarosite and argentojarosite. Textures were also studied in outcrop, on a handspecimen scale, and on microscopic scales to search for evidence of primary sulfides. Sections of ore sample were studied and some links were made to surface textures. These included sedimentary features, bladed and platey hematite, and framboidal structures. Light rare earth minerals (monazites) in the core were an unexpected unusual find as they are not normally associated with sedex style deposits. The monazites may have useful application in dating the deposit or gossan formation.
Enhanced confinement with increased extent of the low magnetic shear region in tokamak plasma

description: The Hamiltonian representation of magnetic field lines enables one to study their confinement properties in tokamaks through the use of symplectic maps such as the symmetric tokamap and its bounded version, the latter being introduced here. In this time-independent purely magnetic framework, we observed the drastic improvement in the confinement of magnetic field lines produced by the local vanishing of the shear profile. This amounts to a non-twist condition that notably acts in the same way the safety profile being (non-strictly) monotonic or having a reversed shear. We single out the effect of the amount of flatness of the safety profile in the vicinity of its zero shear point. All other things being equal, the beneficial effect of the vanishing of the shear profile is shown to be increased if the radial extent of the low-shear region is increased. To be specific, the low-shear region induces the formation of a belt of robust KAM tori acting as an internal transport barrier whose width is all the larger as the extent of the low-shear region is broad.

description: We theoretically study the effect of exchange interaction on the non-equilibrium spin waves in disordered paramagnetic metals under the spin injection condition. We show that the gapless spectrum of spin waves, describing the spin precession in the absence of the applied magnetic field, changes sign to negative on the paramagnetic side near the ferromagnet - paramagnet phase transition. The damping of spin waves is small in the limit when electron-electron exchange energy is larger than the inverse electron mean free time, while in the opposite limit the propagation of spin waves is strongly suppressed. We discuss the amplification of the electromagnetic field by the non-equilibrium spin waves.

The distribution, mineralogy and paragensis of the Hellyer Baritic and Siliceous Caps
Creators: name: Sharpe, R
Publisher: name: University Of Tasmania
Year: 2023

description: Baritic and siliceous caps are a feature of many volcanic-hosted massive sulphide deposits. Their distribution, mineralogy and geochemis~ are important to the understanding of the genesis of these deposits. The baritic and siliceous caps overlying the Hellyer volcanic-hosted massive sulphide deposit, western Tasmania, show a spatial affinity to the centres of hydrothermal activity, identified previously from copper contents of the ore. Mineralogical and textural investigations identified barite as a precursor to formation of the siliceous cap. In both caps intricate sulphide textures, including pristine collofom pyrites, are present Mineralogical and spatial relationships suggest an interdigitation of the baritic and siliceous caps. Sulphur isotope studies of barite (with 034S values between +38 and +50 per mil) and pyrite (with 034-S values between +6 and+ 18 per mil) revealed a duality in the source of sulphur during formation of the caps; incompletely reduced seawater sulphur, and magmatic sulphur. The wide range of o34S values are thought to be the result of fluctuating contributions from these two sulphur sources. Metal zonation and mineral geochemical studies show that base and precious metal contents of both caps are enriched proximal to underlying massive sulphides. In such zones, textural evidence supports hydrothermal overprinting and porosity infill by paragenetically late sulphides. Formation of the barite cap at or above the seawater interface is interpreted to be the result of oxygenated seawater mixing with spent hydrothermal fluids enriched in barium, during periods of low hydrothermal flux, at temperatures between 230 and 250¬¨‚àûC. By contrast, silica cap precipitation requires the local dominance ofH2S and a combination of conductive cooling and mixing. This is evidenced by the presence of arsenopyrite, and the absence of hematite. The interdigitating spatial affmity combined with mineralogical and textural evidence suggests that formation of the baritic and siliceous caps at Hellyer was an integral part of orebody formation. Thus these facies evolved with the growing sulphide mound, in a manner consistent with the rone refming model proposed by Eldridge et al. (1983), for the growth of seafloor sulphide deposits.
Geology and geochemistry of the Que River shale, Western Tasmania
Creators: name: Sinclair, BJ
Publisher: name: University Of Tasmania
Year: 2023

description: The Que River Shale Fonnation overlies the Que-Hellyer Volcanics, which are the host sequence to the Hellyer and Que River massive sulphide deposits, western Tasmania. The Que River Shale is a homogeneous unit of finely laminated, fine grained (<100um)quartz, muscovite and calcite grains in a dirty brown chloritic matrix. The shale contains intercalated resedimented volcaniclatic sandstones at the top and base of the unit. Shale composition varies by less than 5 wt % with regards to major elements. Deposition of the Que River Shale began after the fonnation of the Hellyer Massive sulfide deposit but contemporaneous with the mixed sequence. Shale deposition extended throughout the end of deposition of the Mount Charter group, synchronous with the Southwell Subgroup volcanism. However the erruption of Upper Basalts and Andesites and the influx of predominantly rhyolitic volcaniclastic mass-flows and turbidites associated with the Southwell Subgroup restricted the finely laminated shale mostly to a period of quiesence between the two styles of volcanism. The depositional environment of the Que River Shale is interpreted to represent quiet, reducing bottom waters, due to a high proportion of complete agnostid trilobite specimems along with the presence of carbonaceous material and pyrite nodules. Geochemical techniques have been used to further define the basin as inhospitable (little or no oxygen present) to euxinic (free H2S). While Sisotopes range from o34S + 17 to +43 suggesting that the sediment may have been a closed system with respect to S04 z. ans H2S. The Que River Shale has an andesitic provenance suggesting a local source for the shale. However, the Que River Shale cannot be derived directly from any one source, or combination of sources in the Mount Read Volcanics without significant modification The only quantification that can be placed on the source rocks is that the Que River Shale must contain 20-25% Hellyer Basalt, to obtain the high Cr values observed (up to 1.3 wt % Cr203). The Que River shale must havebeen well homogenised by sedimentary processes to account for its restricted range in chemical composition The Que River shale does not show an extensive alteration plume unlike the underlying basalts. Alteration in the suite therefore cannot be used as an exploration indicator. However, anomalous base metal values (up to 400 ppm Pb and 938 ppm Zn) are spatially association to the orebody and may be useful as vectors to mineralisation.

description: Recent experiments [J. van Mameren et al. PNAS 106, 18231 (2009)] provide a detailed spatial picture of overstretched DNA, showing that under certain conditions the two strands of the double helix separate at about 65 pN. It was proposed that this observation rules out the existence of an elongated, hybridized form of DNA ('S-DNA'). Here we argue that the S-DNA picture is consistent with the observation of unpeeling during overstretching. We demonstrate that assuming the existence of S-DNA does not imply DNA overstretching to consist of the complete or near-complete conversion of the molecule from B- to S-form. Instead, this assumption implies in general a more complex dynamic coexistence of hybridized and unhybridized forms of DNA. We argue that such coexistence can rationalize several recent experimental observations.
The triumph of dynasticism in the Roman imperial succession : from the proclamation of Diocletian to the death of Constantine
Creators: name: Wilson, Edward George
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to trace the constitutional methods by which stability was restored to the Roman Empire after the civil wars of the middle part of the third century. The core of the problem was the lack of any specific laws concerning the appointment of imperial successors and the predominance of the army in the politics of the period. During the first two centuries of the Christian era the hereditary principle, never recognized in law, had brought stability to the imperial succession but the emperor's fundamental role as commander-in-chief of the armies necessitated that the elective principle be invoked by the military in order to oppose the barbarian invasions. The failure of this system became manifest in the decline of imperial unity and indicated that a method had to be devised whereby the succession might become automatic and at the same time might ensure capable military leaders. By an investigation of the ancient literary sources, and especially those which record imperial propaganda, and to a lesser extent the legal codes, inscriptions, and coins, an attempt is made in this thesis to trace the restoration of stability in the imperial succession. This restoration was accomplished in two distinct stages. In the first Diocletian anticipated potential usurpers by associating them with himself in the imperial power. Diocletian's denial of hereditary right led to the downfall of his system, the Tetrarchy, but the restoration of imperial unity enabled the dynastic system to flourish in the second stage under Constantine and his successors.

description: This report presents detailed methods and results from the Burden of Vaccine Preventable Diseases in Australia study which focused on diseases with vaccines on Australia’s National Immunisation Program (NIP) schedule. The study found the rate of vaccine preventable burden decreased by 31% between 2005 and 2015. The decrease was driven by falls for diseases that have had vaccines added to, or vaccine eligibility extended on, the NIP schedule during the past 20 years, such as HPV, pneumococcal disease and rotavirus.

description: We discover an Ising-type duality in the general $N$-state chiral Potts model, which is the Kramers-Wannier duality of planar Ising model when N=2. This duality relates the spectrum and eigenvectors of one chiral Potts model at a low temperature (of small $k'$) to those of another chiral Potts model at a high temperature (of $k'^{-1}$). The $τ^{(2)}$-model and chiral Potts model on the dual lattice are established alongside the dual chiral Potts models. With the aid of this duality relation, we exact a precise relationship between the Onsager-algebra symmetry of a homogeneous superintegrable chiral Potts model and the $sl_2$-loop-algebra symmetry of its associated spin-$\frac{N-1}{2}$ XXZ chain through the identification of their eigenstates.

description: The implementation of ICRP 103 is a huge endeavour in countries with somehow old legislation. As a rule such legislation has been established when very first nuclear reactors have been constructed in the State, e.g. decades ago, and has been later regularly updated. But the implementation of the ICRP 103 is even much bigger challenge in countries with very new radiation safety regulatory framework, e.g. countries which are struggling to put in place their very first regulatory framework. The implementation of the ICRP 103 in legal system within EU Member States as well as IAEA Member States which is still taking place reveals some of the key issues within ICRP 103 which require further evaluation or guides. Namely, in authorization process and later in review and assessment of safety measures and in particular during inspection process it seems that some of the concepts are only poorly understood by users of sources, regulatory staff, qualified experts and other involved in assuring radiation safety. Moreover, it seems that some concepts might require more attention or guides how to implement them. The list of such concept include e.g.: practical implementation of justification principle in non-medical exposure and in particular nonmedical exposure related to sport activities, justification in planned exposure situations as a basic principle and optimisation principle resulting in risk assessment which is somehow used back in the process of justification, re-evaluation of justification in case of pandemic, use of dose constraints for the members of the public set by the authority and relation of such legal arrangement considering legal power of the authority to assure implementation of dose constraints, use of justification at the end of lifecycle, e.g. when managing disused sources, use a reference person in authorization process, optimisation bellow reference levels in e.g. in Radon Action Plan and control of building materials, practical implementation of justification in emergency exposure situations, regarding evacuation as needed in the Fukushima accident. Selected practical examples taken from regulatory experiences are systematically described. Although no major issues were identified when implementing ICRP 103 in ever-day work of regulators, it seems that above mentioned issues require further evolvement of the ICRP system of protection.

description: Material samples are foundational for research across a wide range of biological, environmental, and other interdisciplinary sciences. Their value and the value of the data derived from them depend to a large extent on the way we describe, identify, and reference them in publications and datasets. Use of globally unique and persistent sample identifiers and availability of rich and consistent information (metadata and data) about a sample on the web are critical for making samples and sample data findable, accessible, interoperable, and reusable (FAIR). This guide presents best practices for supporting open science for samples, developed by the Physical Sample Curation Cluster of the Earth Science Information Partners (ESIP) organization. Following this guidance will help ensure that we are able to track use of samples over time, which enables reproducible research, future data integration, reuse, and credit. The ESIP Physical Sample Curation Cluster is a forum for the community supporting physical samples in the earth, space, and environmental sciences. The working group consists of individual researchers who collect and work with physical samples, curators and collections managers, and cyberinfrastructure providers and developers.

Precision cluster mass determination from weak lensing

description: Weak gravitational lensing has been used extensively in the past decade to constrain the masses of galaxy clusters, and is the most promising observational technique for providing the mass calibration necessary for precision cosmology with clusters. There are several challenges in estimating cluster masses, particularly (a) the sensitivity to astrophysical effects and observational systematics that modify the signal relative to the theoretical expectations, and (b) biases that can arise due to assumptions in the mass estimation method, such as the assumed radial profile of the cluster. All of these challenges are more problematic in the inner regions of the cluster, suggesting that their influence would ideally be suppressed for the purpose of mass estimation. However, at any given radius the differential surface density measured by lensing is sensitive to all mass within that radius, and the corrupted signal from the inner parts is spread out to all scales. We develop a new statistic that is ideal for estimation of cluster masses because it completely eliminates mass contributions below a chosen scale (which we suggest should be about 20 per cent of the virial radius), and thus reduces sensitivity to systematic and astrophysical effects. We use simulated and analytical profiles to quantify systematic biases on the estimated masses for several standard methods of mass estimation, finding that these can lead to significant mass biases that range from ten to over fifty per cent. The mass uncertainties when using our new statistic are reduced by up to a factor of ten relative to the standard methods, while only moderately increasing the statistical errors. This new method of mass estimation will enable a higher level of precision in future science work with weak lensing mass estimates for galaxy clusters.

Meiofaunal communities and human impacts at Casey Station, Antarctica
Creators: name: Mohammad, M

description: Marine benthic communities, including meiofauna, have commonly been used as a focus of monitoring programs and of research into the effects of human activities in the marine environment. In Antarctica, benthic communities have been shown to be good indicators of human impacts, however, there is very limited information on Antarctic meiofaunal communities and how they may respond to anthropogenic disturbances. The main types of contamination present in marine sediments around Antarctic stations are metals and hydrocarbons. A survey of sediment meiofaunal communities was done at Casey Station, Antarctica, with sampling at a range of spatial scales, from 10 meters to kilometers, to determine the spatial patterns of community composition and abundance. This included a comparison of control and disturbed areas (adjacent to old waste disposal sites). An MDS of all 47 samples supported by one way ANOSIM (Global R= 0.955, P< 0.001) showed the variation within locations was less than the variation between locations (kms) and significantly different between control and polluted locations. From the total meiofauna, a higher percentage of nematodes, by comparison to harpacticoid copepods in both controlled (nematode, 94.8%: harpacticoid copepods, 5.2%) and disturbed locations (nematode, 95.4%: harpacticoid copepods, 4.6%). Multivariate biological (meiofaunal communities) and environmental datasets were examined to determine whether there were any correlations between patterns of community composition and environmental variables. The analysis suggested that the most influential variables on the community pattern were metals of anthropogenic origin such as tin, lead, iron, copper, and zinc but also metals that probably relate to local differences in mineralogy such as silver, barium, uranium and arsenic. Grain size parameters were found to have a much lower capacity to explain differences in meiofaunal communities, although there did appear to be some influence. An experiment was setup in which four different hydrocarbons (SAB diesel fuel, and clean, used and biodegradable lubricant oils) were added to defaunated marine sediments and deployed in trays in a sheltered marine bay. The communities colonizing the sediments were monitored for up to five years. The effects of hydrocarbon contamination on meiofaunal communities were different for each type of hydrocarbon. The Control and Biodegradable treatments had the most similar meiofaunal communities at all sampling times. Effects of hydrocarbon treatments were still evident after five years. Results also suggest that changes in nematode composition are ideal for long term pollution monitoring. By comparison, copepods appeared to be less sensitive to hydrocarbon pollution. Long-term monitoring is essential to understand the true extent to which lubricants impact the community structure.

description: We analyze the performance of cross-validation (CV) in the density estimation framework with two purposes: (i) risk estimation and (ii) model selection. The main focus is given to the so-called leave-$p$-out CV procedure (Lpo), where $p$ denotes the cardinality of the test set. Closed-form expressions are settled for the Lpo estimator of the risk of projection estimators. These expressions provide a great improvement upon $V$-fold cross-validation in terms of variability and computational complexity. From a theoretical point of view, closed-form expressions also enable to study the Lpo performance in terms of risk estimation. The optimality of leave-one-out (Loo), that is Lpo with $p=1$, is proved among CV procedures used for risk estimation. Two model selection frameworks are also considered: estimation, as opposed to identification. For estimation with finite sample size $n$, optimality is achieved for $p$ large enough [with $p/n=o(1)$] to balance the overfitting resulting from the structure of the model collection. For identification, model selection consistency is settled for Lpo as long as $p/n$ is conveniently related to the rate of convergence of the best estimator in the collection: (i) $p/n\to1$ as $n\to+\infty$ with a parametric rate, and (ii) $p/n=o(1)$ with some nonparametric estimators. These theoretical results are validated by simulation experiments.

description: We study the error threshold of color codes, a class of topological quantum codes that allow a direct implementation of quantum Clifford gates suitable for entanglement distillation, teleportation and fault-tolerant quantum computation. We map the error-correction process onto a statistical mechanical random 3-body Ising model and study its phase diagram via Monte Carlo simulations. The obtained error threshold of p_c = 0.109(2) is very close to that of Kitaev's toric code, showing that enhanced computational capabilities does not necessarily imply lower resistance to noise.

description: We report experimental results on the relative motion of pairs of solid spheric particles with initial separations in the inertial range of fully developed turbulence in water. The particle densities were in the range of $1 \lessapprox ρ_{p}/ρ_{f} \lessapprox 8$, \textit{i.e.}, from neutrally buoyant to highly inertial; and their sizes were of the Kolmogorov scale. For all particles, we observed a Batchelor like regime, in which particles separated ballistically. Similar to the Batchelor regime for tracers, this regime was observed in the early stages of the relative separation for times $t \lessapprox 0.1 t_0$ with $t_0$ determined by the turbulence energy dissipation rate and the initial separation between particle pairs. In this time interval heavier particles separated faster than fluid tracers. The second order Eulerian velocity structure functions was found to increase with density. In other words, both observations show that the relative velocity between inertial particles was larger than that between tracers. Based on the widely used, simplified equation of motion for inertial point-particles, we derived a model that shows an increase in relative velocity between inertial particles. In its scale dependence, however, it disagrees quantitatively with the experimental results. This we attribute to the preferential sampling of the flow field by inertial particles, which is not captured by the model.

description: With the increasing number of highly infectious disease incidents, outbreaks, and pandemics in our society (e.g., Ebola virus disease, Lassa fever, coronavirus diseases), the need for consensus and best practices on highly infectious decedent management is critical. In January 2020, a workshop of subject matter experts from across the world convened to discuss highly infectious live patient transport and highly infectious decedent management best practices. This commentary focuses on the highly infectious decedent management component of the workshop. The absence of guidance or disparate guidance on highly infectious decedent management can increase occupational safety and health risks for death care sector workers. To address this issue, the authorship presents these consensus recommendations on best practices in highly infectious decedent management, including discussion of what is considered a highly infectious decedent; scalability and storage for casualty events; integration of key stakeholders; infection control and facility considerations; transport; care and autopsy; psychological, ethical, and cultural considerations as well as multi-national care perspectives. These consensus recommendations are not intended to be exhaustive but rather to underscore this overlooked area and serve as a starting point for much-needed conversations.
Eating behaviours and cardiovascular disease and diabetes risk in young Australian adults
Creators: name: Smith, KJ
Publisher: name: University Of Tasmania

description: Background: Cardiovascular disease (CVD) and diabetes are major contributors to the burden of disease in Australia and their prevalence is expected to increase with the ageing of the population and the increasing prevalence of obesity. Dietary intake is known to affect cardio-metabolic disease risk but little is known about the eating behaviours of young adults and whether they are associated with diet quality and risk factors for CVD and diabetes. Aims: To investigate whether eating behaviours (involvement in meal preparation; takeaway food consumption; number of daily eating occasions and breakfast skipping) were associated with socio-economic status, lifestyle factors, diet quality and cardio-metabolic risk factors. Methods: Participants were 2,868 Australian adults aged 26-36 years enrolled in the Childhood Determinants of Adult Health study, a follow-up to the 1985 Australian Schools Health and Fitness Survey. Participants completed a food frequency questionnaire, a food habits questionnaire and a meal patterns chart. In childhood, participants were asked if they usually ate before school. Cardio-metabolic risk factors assessed in adulthood included waist circumference, fasting glucose, fasting insulin and lipids. Results: Participants who were single, less educated, current smokers and less physically active tended to be higher consumers of takeaway food, eat fewer times per day and skip breakfast. Frequent takeaway food consumption, having a low number of daily eating occasions and skipping breakfast as an adult were behaviours associated with poorer diet quality. In addition, those who ate takeaway at least twice per week, had low number of daily eating occasions (men only), and skipped breakfast both as a child and an adult had a larger waist circumference compared to those who did not have these eating behaviours. Involvement in meal preparation was not strongly associated with diet quality or weight status. Cardio-metabolic risk factors were associated with eating behaviours: fasting glucose, insulin and HOMA with frequent takeaway food consumption for women; fasting glucose, insulin and lipids with low number of eating occasions for men; and fasting insulin, total and LDL cholesterol with skipping breakfast in both childhood and adulthood. Conclusions: Eating behaviours were associated with diet quality and cardio-metabolic risk factors in young Australian adults. Simple public health messages that promote limiting takeaway food consumption to once per week and the importance of not skipping breakfast may help reduce the risk of CVD and type 2 diabetes.

description: The Cathode Strip Chambers (CSCs) constitute the primary muon tracking device in the CMS endcaps. Their performance has been evaluated using data taken during a cosmic ray run in fall 2008. Measured noise levels are low, with the number of noisy channels well below 1%. Coordinate resolution was measured for all types of chambers, and fall in the range 47 microns to 243 microns. The efficiencies for local charged track triggers, for hit and for segments reconstruction were measured, and are above 99%. The timing resolution per layer is approximately 5 ns.
