The work is made available under the Creative Commons CC0 public domain dedication. The purpose of this study is to evaluate the ability of quantitative magnetic resonance imaging (MRI) to discriminate between skin biopsies from individuals with osteogenesis imperfecta (OI) and skin biopsies from individuals without OI. Skin biopsies from nine controls (unaffected) and nine OI patients were imaged to generate maps of five separate MR parameters, T1 ,T2 ,km , MTR and ADC. Parameter values were calculated over the dermal region and used for univariate and multiparametric classification analysis. A substantial degree of overlap of individual MR parameters was observed between control and OI groups, which limited the sensitivity and specificity of univariate classification. Classification accuracies ranging between 39% and 67% were found depending on the variable of investigation, with T2 yielding the best accuracy of 67%. When several MR parameters were considered simultaneously in a multivariate analysis, the classification accuracies improved up to 89% for specific combinations, including the combination of T2 and km . These results indicate that multiparametric classification by quantitative MRI is able to detect differences between the skin of OI patients and of unaffected individuals, which motivates further study of quantitative MRI for the clinical diagnosis of OI.

description: The economic competitiveness of hydrogen-powered aviation highly depends on the supply costs of green liquid hydrogen to enable true-zero CO2 flying. This study uses non-linear energy system optimization to analyze three main liquid hydrogen (LH2) supply pathways for five locations. Final liquid hydrogen costs at the dispenser supply costs could reach 2.04 USD/kgLH2 in a 2050 base case scenario for locations with strong renewable energy source conditions. This could lead to cost-competitive flying with hydrogen. Reflecting techno-economic uncertainties in two additional scenarios, the liquid hydrogen cost span at all five airport locations ranges between 1.37–3.48 USD/kgLH2, if hydrogen import options from larger hydrogen markets are also available. Import setups are of special importance for airports with a weaker renewable energy source situation, e.g., selected Central European airports. There, on-site supply might not only be too expensive, but space requirements for renewable energy sources could be too large for feasible implementation in densely populated regions. Furthermore, main costs for liquid hydrogen are caused by renewable energy sources, electrolysis systems, and liquefaction plants. Seven detailed design rules are derived for optimized energy systems for these and the storage components. This and the cost results should help infrastructure planners and general industry and policy players prioritize research and development needs.

description: © 2016 Chaurio et al. Transmission-blocking (TB) vaccines are considered an important tool for malaria control and elimination. Among all the antigens characterized as TB vaccines against Plasmodium vivax, the ookinete surface proteins Pvs28 and Pvs25 are leading candidates. These proteins likely originated by a gene duplication event that took place before the radiation of the known Plasmodium species to primates. We report an evolutionary genetic analysis of a worldwide sample of pvs28 and pvs25 alleles. Our results show that both genes display low levels of genetic polymorphism when compared to the merozoite surface antigens AMA-1 and MSP-1; however, both ookinete antigens can be as polymorphic as other merozoite antigens such as MSP-8 and MSP-10. We found that parasite populations in Asia and the Americas are geographically differentiated with comparable levels of genetic diversity and specific amino acid replacements found only in the Americas. Furthermore, the observed variation was mainly accumulated in the EGF2- and EGF3-like domains for P. vivax in both proteins. This pattern was shared by other closely related non-human primate parasites such as Plasmodium cynomolgi, suggesting that it could be functionally important. In addition, examination with a suite of evolutionary genetic analyses indicated that the observed patterns are consistent with positive natural selection acting on Pvs28 and Pvs25 polymorphisms. The geographic pattern of genetic differentiation and the evidence for positive selection strongly suggest that the functional consequences of the observed polymorphism should be evaluated during development of TBVs that include Pvs25 and Pvs28.
And so it is : a group of short stories

description: "And So It ls" is a group of eight short stories which were written to be read aloud. The reader should lead with his ear and follow with his eye. The story is in the sound, in the details, in the motion, and not in the plot or the characters. What happens is in no sense important; how it happens, is. All of my writing is based on incidents which did occur. So, "And Etc." is the story of a girl about to write an exam; "With My People" is about an Indian student who once wrote a paper for me as a teacher; "Where They Are," "Such As It Is," "They Know What They're Doing," "Other Men Make The," "A Single Scrambled," and "Some Trip This Is Going To Be" are stories of a girl's first introduction to boat-life as a mess-girl on a west-coast freighter. I attempt neither to enlarge nor diminish events, but naturally they change, take shape, assume a form as I write. So, although various listeners have called my fiction comic, symbolic, realistic, absurd, poetic, literal, imaginative, all I can say is that these stories are based on incidents which did occur and that they are oral.
On group invariant solutions to the Maxwell Dirac equations
Creators: name: Legg, GP
Publisher: name: University Of Tasmania
Year: 2023

description: This work constitutes a study on group invariant solutions of the Maxwell Dirac equations for a relativistic electron spinor in its own self-consistent electromagnetic field. First, the Maxwell Dirac equations are written in a gauge independent tensor form, in terms of bilinear Dirac currents and a gauge independent total four-potential. A requirement of this form is that the length of the current vector be non-zero. In this form they are amenable to the study of solutions invariant under subgroups of the Poincare group without reference to the Abelian gauge group. In particular, all subgroups of the Poincare group that generate 4 dimensional orbits by transitive action on Minkowski space, and the corresponding invariant vector fields are identifed, which will constitute invariant solutions merely if various constants satisfy a set of algebraic equations. For each such subgroup, the possibility of solutions to both the full Maxwell Dirac equations and to a classical approximation to the self-field equations is determined. Of the 19 classes of simply transitive subgroups, only one class yielded a solution.

description: © Mego et al. CTCs are involved in tumor dissemination and are an independent prognostic factor in primary and metastatic breast cancer patients. Dendritic cells (DCs) are the most efficient antigen presenting cells and are comprised of plasmacytoid-(pDC) and myeloid-(mDC) derived DC subsets. This study aimed to correlate CTC counts with the peripheral blood DC immunophenotypes and functions of inflammatory breast cancer (IBC) patients. This study included 65 IBC patients. Peripheral blood (PB) was obtained from patients prior to starting a new line of chemotherapy for CTCs enumeration by CellSearch® and DC phenotype and function by flow cytometry; the characteristics of DCs were then correlated with CTC counts and clinical outcome. Twenty-one (32.3%) patients with CTCs ≥5 had a significantly inferior overall survival (OS) compared to patients with <5 CTCs (p=0.045). In addition, patients with ≥5 CTCs had a lower percentage of mDCs capable of producing TNF-a before or after activation through the toll-like receptor (TLR), as well as a lower percentage of mDCs producing IL-12 after TLR-activation. There was a positive correlation between CTCs counts and expression of the activation (CCR7) and costimulatory (CD86) receptors on TLR-activated mDCs and pDCs, respectively. Moreover, presence of high percentage of mDC capable to produce increased levels of TNF-a was independently associated with inferior OS (p = 0.0006). An increase in the percentage of mDC producing TNF-a might induce a proinflammatory environment that could play a role in determining the poor clinical outcome in IBC patients and could add further prognostic value to CTCs.

description: A large sample of cosmic ray events collected by the CMS detector is exploited to measure the specific energy loss of muons in the lead tungstate of the electromagnetic calorimeter. The measurement spans a momentum range from 5 GeV/c to 1 TeV/c. The results are consistent with the expectations over the entire range. The calorimeter energy scale, set with 120 GeV/c electrons, is validated down to the sub-GeV region using energy deposits, of order 100 MeV, associated with low-momentum muons. The muon critical energy in lead tungstate is measured to be 160+5/-6 plus or minus 8 GeV, in agreement with expectations. This is the first experimental determination of muon critical energy.
A real-time spatio-temporal data exploration tool for marine research
Creators: name: Veness, A D
Publisher: name: University Of Tasmania
Year: 2023

description: The resources required to acquire high quality scientific data in a marine environment can be great. The complication of acquiring data from a platform which pitches, rolls and heaves makes the challenge even greater. The variability of the weather and sea conditions, along with equipment failures, seemingly conspire against the marine scientist. There is a great need for good quality-control measures, accurate electronic record keeping, and effective voyage management at sea if a good outcome from an expensive sea voyage is to be expected. Typically, the plethora of navigation, data acquisition, quality control, Geographical Information Systems and databases used at sea on the world's research vessels do not allow an intuitive, holistic, spatial and temporal view of real-time data. How close are we to the ship track from our last visit to the region?‚ÄövÑvp or What was the deployment depth of the instrument when we were last at this site two years ago?‚ÄövÑvp are typical questions asked by those undertaking research far from shore. Answering these questions like these, in a timely manner, using systems commonly used on research vessels can be difficult. This study explored the combination of an open-source spatio-temporal DataBase Management System (DBMS) and Keyhole Markup Language (KML), creating a framework for the storage and exploration of real-time spatio-temporal data at sea. The framework supported multiple concurrent users using Virtual Globe browsers. This study created a methodology, which resulted in a functional software tool, MARVIN, using open-source software. Empirical and modelled datasets were used in conjunction with MARVIN, both at sea and in the laboratory. MARVIN was found to be able to provide a simple and intuitive 4D (3D + time) real-time view of spatio-temporal datasets, as they were collected at sea. The key combination of a spatio-temporal DBMS and KML, offered a robust solution for the storage of real-time data, undertaking of Geographical Information System (GIS) operations, and streaming of data to multiple clients, running Virtual Globe browsers such as Google Earth. The techniques implemented also support existing navigation, GIS, and numeric modelling software commonly used on modern research vessels.

description: © 2016, The Author(s). Objective: To examine the extent to which mindfulness skills influence psychological distress and health-related quality of life (HRQOL) in men with metastatic or castration-resistant biochemical progression of prostate cancer. Patients and methods: A cross-sectional survey of 190 men (46 % response; mean age 71 years, SD = 8.7, range 40–91 years) with advanced prostate cancer, assessed psychological and cancer-specific distress, HRQOL. Mindfulness skills were assessed as potential predictors of adjustment outcomes. Results: Overall, 39 % of men reported high psychological distress. One third had accessed psychological support previously although only 10 % were under current psychological care. One quarter had accessed a prostate cancer support group in the past six months. Higher HRQOL and lower cancer-specific and global psychological distress were related to non-judging of inner experience (p

Our approach is universal in the sense that we do not employ any approximations apart from the large-$N$ limit. The final result is nonperturbative in N, i.e., it cannot be obtained by %the usual an expansion in 1/N, and we obtain far less topological defects than quasiparticle excitations, in sharp distinction to previous, low-dimensional investigations.

Constituting the quarantine protection of islands designated IUCN Category 1a protected areas - theoretical and practical perspectives.
Creators: name: Potter, S
Publisher: name: University Of Tasmania
Year: 2023

description: The successful protection of sites of high conservation value from the unintentional introduction of species necessitates an understanding of the drivers and impediments to action, and the manner in which research, policy development and praxis interface to constitute an appropriate level of protection - in theory and in practice. Factors bearing on how the quarantine protection of such sites is constituted are usefully explored in relation to islands - on account of the heightened planning considerations associated with their geographies and destination appeal, and their relatively small size, notionally defendable edges and oft-cited vulnerability and importance as refuges for rare and endangered species. Eight Australian Islands designated IUCN Category 1a Protected Areas (Strict Nature Reserves) were selected as case studies using a mixed, purposeful sampling strategy that deferred to each case's likely intrinsic merit in illustrating a diversity of protection issues, and in providing balance and variety of information. Insights into biosecurity praxis were elicited by conducting semi-structured interviews with policy makers, land managers and the proponents of island activities; reviewing the grey literature of stakeholder agencies; and observing quarantine management practices. Factors found to impact upon praxis included perspectives held about the activities providing for introductions and the extent to which these pathways can and need to be managed, how non-indigenous species issues are articulated and scoped, the sometimes default and problematic reliance placed on quarantine arrangements constituted at the national level, the degree to which land management agencies and land users are compelled to act and perspectives on the efficacy of past protection efforts.

description: We use the ellipsoidal collapse approximation to investigate the nonlinear redshift space evolution of the density field with primordial non-Gaussianity of the local f_{nl}-type. We utilize the joint distribution of eigenvalues of the initial non-Gaussian shear field and evaluate the evolved redshift space probability distribution function (PDF). It is shown that, similar to the real space analysis, the underdense tail of the nonlinear redshift space PDF differs significantly from that for Gaussian initial conditions. We also derive the lowest order correction of the Kaiser's formulain the presence of a non-zero f_{nl}.

description: We suggest that planets, brown dwarfs, and even low mass stars can be formed by fragmentation of protoplanetary disks around very massive stars M>~100 solar masses. We discuss how fragmentation conditions make the formation of very massive planetary systems around very massive stars favorable. Such planetary systems are likely to be composed of brown dwarfs and low mass stars of ~0.1-0.3 solar masses, at orbital separations of ~ few x 100 - 10^4 AU. In particular, scaling from solar-like stars suggests that hundreds of Mercury-like planets might orbit very massive stars at ~1000 AU, where conditions might favor liquid water. Such fragmentation objects can be excellent targets for the James Webb Space Telescope and other large telescopes working in the IR bands. We predict that deep observations of very massive stars would reveal these fragmentation objects, orbiting in the same orbital plane in cases where there are more than one object.

description: It is well known that the triviality problem for finitely presented groups is unsolvable; we ask the question of whether there exists a general procedure to produce a non-trivial element from a finite presentation of a non-trivial group. If not, then this would resolve an open problem by J. Wiegold: `Is every finitely generated perfect group the normal closure of one element?' We prove a weakened version of our question: there is no general procedure to pick a non-trivial generator from a finite presentation of a non-trivial group. We also show there is neither a general procedure to decompose a finite presentation of a non-trivial free product into two non-trivial finitely presented factors, nor one to construct an embedding from one finitely presented group into another in which it embeds. We apply our results to show that a construction by Stallings on splitting groups with more than one end can never be made algorithmic, nor can the process of splitting connect sums of non-simply connected closed 4-manifolds.

description: Climate change drives a northward shift of biomes in high-latitude regions. This might have consequences on the decomposition of plant litter entering the soil, including its lignin component, which is one of the most abundant components of vascular plants. In order to elucidate the combined effect of climate and soil characteristics on the decomposition pattern of lignin, we investigated lignin contents and its degree of oxidative decomposition within soil profiles along a climosequence in western Siberia. Soil samples were collected from organic topsoil to mineral subsoil at six sites along a 1500-km latitudinal transect, stretching from tundra, through taiga and forest steppe to typical steppe. The stage of lignin degradation, as mirrored by decreasing organic carbon-normalized lignin contents and increasing oxidative alteration of the remnant lignin (acid-to-aldehyde ratios of vanillyl- and syringyl-units [(Ac/Al)V and (Ac/Al)S]) within soil horizons, increased from tundra to forest steppe and then decreased to the steppe. Principal component analysis, involving also climatic conditions such as mean annual temperature and aridity index, showed that the different states of lignin degradation between horizons related well to the activity of phenoloxidases and peroxidases, enzymes involved in lignin depolymerization that are produced primarily by fungi and less importantly by bacteria. The low microbial lignin decomposition in the tundra was likely due to low temperature and high soil moisture, which do not favour the fungi. Increasing temperature and decreasing soil moisture, facilitating a higher abundance of fungi, led to increased fungal lignin decomposition towards the forest-steppe biome, while drought and high pH might be responsible for the reduced lignin decomposition in the steppe. We infer that a shift of biomes to the north, driven by climate change, might promote lignin decomposition in the northern parts, whereas in the south a further retardation might be likely.

In contrast with expectations from tensor network renormalization (TNR), we show that a simple, explicit analytic description of this fixed point using operator-algebraic renormalization (OAR) is possible. Specifically, the fixed point is characterized in terms of spin-spin correlation functions. Explicit error bounds for the approximation of continuum correlation functions are given.

We study the interplay between the oscillations of $T_c$ due to the Little--Parks effect and the oscillations due to the exchange field. We demonstrate that the exchange field provokes the switching between the superconducting states with different vorticities and this may result in the increase the critical temperature of the superconducting transition in the magnetic field. Moreover we analyse the influence of the S/F transparency on the realisation of the states with higher vorticities.

description: The Collaborative Research Center 1153 is investigating a novel process chain for manufacturing high-performance hybrid components. The combination of aluminum and steel can reduce the weight of components and lead to lower fuel consumption. During the welding of aluminum and steel, a brittle intermetallic phase is formed that reduces the service life of the component. After welding, the workpiece is heated inhomogeneously and hot-formed in a cross-wedge rolling process. Since the intermetallic phase grows depending on the temperature during hot forming, temperature control is of great importance. In this paper, the possibility of process-integrated contact temperature measurement with thin-film sensors is investigated. For this purpose, the initial temperature distribution after induction heating of the workpiece is determined. Subsequently, cross-wedge rolling is carried out, and the data of the thin-film sensors are compared to the temperature measurements after heating. It is shown that thin-film sensors inserted into the tool are capable of measuring surface temperatures even at a contact time of 0.041 s. The new process monitoring of the temperature makes it possible to develop a better understanding of the process as well as to further optimize the temperature distribution. In the long term, knowledge of the temperatures in the different materials also makes it possible to derive quality characteristics as well as insights into the causes of possible process errors (e.g., fracture of the joining zone).
The Spurling legacy and the emergence of wilderness photography in Tasmania
Creators: name: Burgess, CH
Publisher: name: University Of Tasmania
Year: 2023

description: During the nineteenth and early twentieth centuries, the Spurling photographic firm made a significant contribution to photography in Tasmania. However, over the years, fact and fiction about the Spurlings became confused. Their photographs became dispersed and inaccessible. Then, in the late 1970s a series of co-incidences led to the re-discovery of a large number of photographic glass plates. Some Spurling-related research commenced and then lapsed. Since then, with the exception of a few dedicated investigators, the Spurlings' contribution to Australian photography has remained largely untold. The task of this research was to redress this situation by locating, worldwide, as many Spurling images as possible, to catalogue and date them, and then to investigate relevant contextual information. This data was then placed into an historical and social framework. The thesis examines the careers of the three generations of Spurling photographers -- Stephen 1st, his two photographer sons Stephen 2nd and Frederick, and his grandson Stephen 3rd. It describes and analyses their cumulative photographic achievements from the early 1840s through to 1941, and traces their move from portraiture through to scenic, and ultimately wilderness photography. It also examines Stephen 3rd's significant wilderness treks and looks at the artistic and photographic conventions that influenced the ways in which the Spurlings depicted the landscape. Other subjects considered include issues surrounding the production of these images, and how wilderness photography can play an important role in alerting the public to environmental conservation. By examining these issues, this thesis adds significantly to the current literature on Australian photographic history. Although many photo-historians refer to the Spurlings, most have either overlooked or dismissed the significance of the Spurlings' photographic legacy, or provided only brief overviews. This thesis argues that while some of the factors that led to the Spurlings' virtual disappearance from the historical record were due to external influences and prejudices, the Spurlings themselves did little to record their history for posterity. This was due in part to modesty, but also a desire to keep family secrets hidden. This thesis concludes with a call for more accurate, unbiased and data-driven accounts of early Tasmanian photography, and a re-assessment of the Spurlings' place in Australian photographic history.

description: We investigate the properties of heavy quarkonia at finite temperature in detail using QCD sum rules. Extending previous analyses, we take into account a temperature dependent effective continuum threshold and derive constraints on the mass, the width, and the varying effective continuum threshold. We find that at least one of these quantities of a charmonium changes abruptly in the vicinity of the phase transition. We also calculate the ratio of the imaginary time correlator to its reconstructed one, $G/G_{\text{rec}}$, by constructing a model spectral function and compare it to the corresponding lattice QCD results. We demonstrate that the almost constant unity of $G/G_{\text{rec}}$ can be obtained from the destructive interplay of the changes in each part of the spectral modification which are extracted from QCD sum rules.

A common magnetic behavior is detected for all the three families, demonstrating negligible effects of the isovalent Y-substituent disorder. Two distinct regimes are identified, separated by a crossover, whose origin is attributed to the concurrent thermal activation of spin and charge degrees of freedom: a thermally activated and a re-entrant quenched-hole antiferromagnetic regime. The peculiar temperature and hole density dependence of the magnetic moment m(h,T) fit a model with a (spin) activation energy for the crossover between the two regimes throughout the entire investigated range. The magnetic moment is suppressed by a simple dilution mechanism both in the reentrant regime (0

description: When a generic quantum system is prepared in a simple initial condition, it typically equilibrates toward a state that can be described by a thermal ensemble. A known exception is localized systems that are non-ergodic and do not thermalize; however, local observables are still believed to become stationary. Here we demonstrate that this general picture is incomplete by constructing product states that feature periodic high-fidelity revivals of the full wavefunction and local observables that oscillate indefinitely. The system neither equilibrates nor thermalizes. This is analogous to the phenomenon of weak ergodicity breaking due to many-body scars and challenges aspects of the current phenomenology of many-body localization, such as the logarithmic growth of the entanglement entropy. To support our claim, we combine analytic arguments with large-scale tensor network numerics for the disordered Heisenberg chain. Our results hold for arbitrarily long times in chains of 160 sites up to machine precision.

description: Flapan--Naimi--Pommersheim showed that every spatial embedding of $K_{10}$, the complete graph on ten vertices, contains a non-split three-component link; that is, $K_{10}$ is intrinsically triple-linked in $\mathbb{R}^3$. The work of Bowlin--Foisy and Flapan--Foisy--Naimi--Pommersheim extended the list of known intrinsically triple-linked graphs in $\mathbb{R}^3$ to include several other families of graphs. In this paper, we will show that while some of these graphs can be embedded 3-linklessly in $\mathbb{R}P^3$, $K_{10}$ is intrinsically triple-linked in $\mathbb{R}P^3$.

description: The kidney flushes out toxic substances and metabolic waste products, and homeostasis is maintained owing to the kidney efforts. Unfortunately, kidney disease is one of the illnesses with a poor prognosis and a high death rate. The current investigation was set out to assess erythropoietin (EPO) potential therapeutic benefits against thioacetamide (TAA)-induced kidney injury in rats. EPO treatment improved kidney functions, ameliorated serum urea, creatinine, and malondialdehyde, increased renal levels of reduced glutathione, and slowed the rise of JAK2, STAT5, AMPK, and their phosphorylated forms induced by TAA. EPO treatment also greatly suppressed JAK2, Phosphatidylinositol 3-kinases, and The Protein Kinase R-like ER Kinase gene expressions and mitigated the histopathological alterations brought on by TAA toxicity. EPO antioxidant and anti-inflammatory properties protected TAA-damaged kidneys. EPO regulates AMPK, JAK2/STAT5, and pro-inflammatory mediator synthesis.

description: Motivated by the possible mechanism for the pinning of the electronic liquid crystal direction in YBCO as proposed in \cite{Pardini08}, we use the first principles Monte Carlo method to study the spin 1/2 Heisenberg model with antiferromagnetic couplings $J_{1}$ and $J_{2}$ on the square lattice. The corresponding low-energy constants, namely the spin stiffness $ρ_s$, the staggered magnetization density ${\cal M}_s$, the spin wave velocity $c$, as well as the ground state energy density $e_0$ are determined by fitting the Monte Carlo data to the predictions of magnon chiral perturbation theory. In particular, the spin stiffnesses $ρ_{s1}$ and $ρ_{s2}$ are investigated as a function of the ratio $J_{2}/J_{1}$ of the couplings. Although we find a good agreement between our results with those obtained by the series expansion method in the weakly anisotropic regime, for strong anisotropy we observe discrepancies.

Annie Baxter in Van Diemen's Land : an abridged and annotated version of her journal, 1834 ‚Äö- 1851
Creators: name: Sherwood, TA
Publisher: name: University Of Tasmania
Year: 2023

description: The day after Annie Baxter embarked with her husband, a British army officer, on the Augusta Jessie to travel to the Australian colonies, she began a journal which she maintained for the next thirty-four years. This thesis presents an edited scholarly edition of those sections of Annie Baxter's extant manuscript journal which record her five visits to Van Diemen's Land and her experiences in the colony between 1835 and 1851, together with a detailed commentary. During her first visit she resided in Launceston with her husband for almost four years; subsequently she visited alone, travelling each time from Yambuk, a grazing property in the Portland region of Port Phillip. After her initial visit in the 1830s, she made three visits between November 1844 and February 1849 for periods which varied in length from three to seven months, to stay with her brother, a Royal Engineer then stationed in Hobart Town. From June 1849 she lived in Hobart Town with her brother following the death of his wife, before returning to England in January 1851. The text of Annie Baxter's journal included in this thesis maps Annie's experiences at a difficult and eventful time of her life in a particular colonial location, while also tracing the journal's development as a serial life writing project. Stylistically, I refrain in the thesis from aesthetic evaluation of the journal but emphasise its complexity as literary endeavour. And while these aspects of the journal are explored, in line with the requirements of responsible scholarly editing, care has been taken to preserve the integrity of the manuscript in terms of the writer's preoccupations, emphasis, and interest. The thesis comprises a general introduction which provides necessary background material and establishes editorial practice, then an abridged reading text presented in four parts: one for each of the first, fourth and fifth visits, while the journal records of the second and third visits are presented together. Each of the four parts is supported by an introductory essay that contextualises the journal record and provides relevant cultural and stylistic commentary, and annotations which are both interpretative and explanatory. The thesis is completed with a full electronic transcription to accommodate the imperative for editorial transparency.
The phase diagram of the extended anisotropic ferromagnetic-antiferromagnetic Heisenberg chain

description: By using Density Matrix Renormalization Group (DMRG) technique we study the phase diagram of 1D extended anisotropic Heisenberg model with ferromagnetic nearest-neighbor and antiferromagnetic next-nearest-neighbor interactions. We analyze the static correlation functions for the spin operators both in- and out-of-plane and classify the zero-temperature phases by the range of their correlations. On clusters of $64,100,200,300$ sites with open boundary conditions we isolate the boundary effects and make finite-size scaling of our results. Apart from the ferromagnetic phase, we identify two gapless spin-fluid phases and two ones with massive excitations. Based on our phase diagram and on estimates for the coupling constants known from literature, we classify the ground states of several edge-sharing materials.

description: The mean-square displacement (MSD) was measured by neutron scattering at various temperatures and pressures for a number of molecular glass-forming liquids. The MSD is invariant along the glass-transition line at the pressure studied, thus establishing an ``intrinsic'' Lindemann criterion for any given liquid. A one-to-one connection between the MSD's temperature dependence and the liquid's fragility is found when the MSD is evaluated on a time scale of approximately 4 nanoseconds, but does not hold when the MSD is evaluated at shorter times. The findings are discussed in terms of the elastic model and the role of relaxations, and the correlations between slow and fast dynamics are addressed.

ICRP and a Century of Governance and Ethics for Radiation Protection in Medicine

description: This paper is based on the governance framework for radiation protection in medicine over the 125 years since Roentgen discovered X-rays. However most the material relates to the period since 1928, during which ICRP and its predecessors were key players. Much of it mines the online archive of ICRP reports, and the paper would not have been possible without open access to these. The paper has been published on an open access basis by Physica Medica. It places the attempts to deal with the harms and inappropriate activities side by side with positive developments. Its narrative is based on the Recommendations of ICRP as they evolved over time — interrogated with respect to governance and ethics. The governance commentary is based on assessing the independence of ICRP and the scope of its recommendations re medical exposures. While it has generally asserted its independence it has, perhaps, been too close to an International Radiological professional body and this may be reflected in the recommendations. In terms of ethics, the recommendations are reviewed in the light of values that are deemed appropriate to both medical ethics and radiation protection. There has been much to celebrate, but there are also significant ethics deficits some of which are currently being addressed. At a more fundamental level, the commission’s attempts to create a rigorous quantitative scientific framework for the trade-off between benefits and harms may be overambitious. It may prove necessary to follow the science and give more prominence to uncertainty in the future. The commission’s work has been formative and important, but much more can be achieved to guide medical uses of radiation into the future.
