description: The efficacy of vitamin D3 in preventing fractures and falls has been explored in a number of clinical trials. However, recent evidence revealed new questions about the adequate doses of vitamin D3 supplementation and its efficacy in fracture prevention independent of calcium supplements for various types of fractures. To conduct a meta-analysis to estimate the effectiveness of 800 IU daily vitamin D3 supplementation for increasing bone mineral density (BMD) and preventing fractures in postmenopausal women. Medline and EMBASE were searched for controlled trials comparing the effectiveness of cholecalciferol (vitamin D3) against placebo with or without background calcium supplementation in the treatment of postmenopausal women. Eight controlled trials evaluating the effect of vitamin D3 supplementation with or without calcium were assessed. Of 12 658 women included in a Bayesian meta-analysis, 6089 received vitamin D3 (with or without calcium) and 6569 received placebo (with or without calcium). Compared to placebo, vitamin D3 with calcium supplementation showed beneficial effects on the incidence of non-vertebral (odds ratio [OR] 0.77, 95% credibility limit [CL] 0.6–0.93) and hip (OR 0.70, 95% CL 0.53–0.90) fractures, while the effects on non-vertebral-non-hip fractures (OR 0.84, 95% CL 0.67–1.04) % point increase) were associated with more uncertainty. Vitamin D3 supplementation showed a 70% probability of being a better treatment than placebo for the prevention of non-vertebral fractures, hip fractures, and non-vertebral, non-hip fractures. Compared to calcium supplementation, vitamin D3 plus calcium reduced non-vertebral fractures (OR 0.68, 95% CL 0.43–1.01) and non-vertebral, non-hip fractures (OR 0.64, 95% CL 0.38–0.99), but did not reduce hip fractures (OR 1.03, 95% CL 0.39–2.25). Key limitations to this analysis include a small number of studies and heterogeneity in the study populations. This meta-analysis supports the use of vitamin D3 of 800 IU daily to reduce the incidence of osteoporotic non-vertebral, hip, and non-vertebral-non-hip fractures in elderly women. Vitamin D3 with calcium appears to achieve benefits above those attained with calcium supplementation alone for non-vertebral and non-vertebral-non-hip fractures.

description: Given the dependency of current CNN architectures on a large training set, the possibility of using synthetic data is alluring as it allows generating a virtually infinite amount of labeled training data. However, producing such data is a non-trivial task as current CNN architectures are sensitive to the domain gap between real and synthetic data. We propose to adopt general-purpose GAN models for pixel-level image translation, allowing to formulate the domain gap itself as a learning problem. The obtained models are then used either during training or inference to bridge the domain gap. Here, we focus on training the single-stage YOLO6D object pose estimator on synthetic CAD geometry only, where not even approximate surface information is available. When employing paired GAN models, we use an edge-based intermediate domain and introduce different mappings to represent the unknown surface properties. Our evaluation shows a considerable improvement in model performance when compared to a model trained with the same degree of domain randomization, while requiring only very little additional effort.

Introduction to 'Art and Modern Copyright: The Contested Image' (CUP, 2018)
Creators: name: Cooper, Elena
Publisher: name: Zenodo
Year: 2021

description: This Working Paper is a re-print of the introductory chapter of the monograph ‘Art and Modern Copyright: The Contested Image’ published as part of the Cambridge Intellectual Property and Information Law series by Cambridge University Press in 2018. Art and Modern Copyright is the first in-depth and longitudinal account of the history of copyright relating to the visual arts and concerns the protection of painting, engraving and photography in the UK 1850-1911. Together with the copyright history monographs discussed in the accompanying CREATe Working Paper ‘Copyright History in Review’ (Working Paper 2021/3), Art and Modern Copyright can be seen as part of a new wave of recently published scholarship which shifts the focus of copyright history away from its longstanding concern with the protection of books and literary works, to other subject matter (visual arts, drama and news). The Introduction to Art and Modern Copyright argues that art added something new to the making of modern copyright law in the UK – the history of artistic copyright was in many respects distinct from the history of literary copyright – and provides an overview of the thematic chapters of the book that substantiate that claim: the protection of copyright ‘authors’ (i.e. the claims to protection advanced by painters, photographers and engravers), art collectors, sitters and the public interest. It also makes a number of more general claims about the value of copyright history. In particular, rather than looking to history to uncover a point of origin or foundational moment, Dr Cooper explores the value of history as a destabilising influence. In taking us to ways of thinking about copyright that, in some respects, differ starkly from our own and have no authority today or continuity with the present, history can sharpen the critical lens through which we view current copyright debates and lend to us a more flexible way of thinking through legal challenges today. Art and Modern Copyright was shortlisted by the Society of Legal Scholars for the Birks Book Prize for Outstanding Legal Scholarship in 2020. Drawing on extensive original archival work made possible by a Peter Orton Fellowship at Trinity Hall Cambridge, it significantly extends a PhD thesis (concerning photographic copyright only) supervised by Lionel Bently at Cambridge University, which was awarded a Yorke Prize by the Faculty of Law, Cambridge in 2011.

description: Transfer learning from natural images to medical images has been established as one of the most practical paradigms in deep learning for medical image analysis. To fit this paradigm, however, 3D imaging tasks in the most prominent imaging modalities (e.g., CT and MRI) have to be reformulated and solved in 2D, losing rich 3D anatomical information, thereby inevitably compromising its performance. To overcome this limitation, we have built a set of models, called Generic Autodidactic Models, nicknamed Models Genesis, because they are created ex nihilo (with no manual labeling), self-taught (learnt by self-supervision), and generic (served as source models for generating application-specific target models). Our extensive experiments demonstrate that our Models Genesis significantly outperform learning from scratch and existing pre-trained 3D models in all five target 3D applications covering both segmentation and classification. More importantly, learning a model from scratch simply in 3D may not necessarily yield performance better than transfer learning from ImageNet in 2D, but our Models Genesis consistently top any 2D/2.5D approaches including fine-tuning the models pre-trained from ImageNet as well as fine-tuning the 2D versions of our Models Genesis, confirming the importance of 3D anatomical information and significance of Models Genesis for 3D medical imaging. This performance is attributed to our unified self-supervised learning framework, built on a simple yet powerful observation: the sophisticated and recurrent anatomy in medical images can serve as strong yet free supervision signals for deep models to learn common anatomical representation automatically via self-supervision. As open science, all codes and pre-trained Models Genesis are available at https://github.com/MrGiovanni/ModelsGenesis.

description: We present new high-sensitivity high-resolution mm-wave observations of the Onsala 1 ultra-compact HII region that bring to light the internal structure of this massive star forming cloud. The 1.2 mm continuum map obtained with the IRAM 30-m radiotelescope (~11" resolution) shows a centrally peaked condensation of 1' size (~0.5 pc at the assumed distance of 1.8 kpc) which has been further investigated at higher resolution in the 3 mm continuum and in the emission lines of H13CO+ J=1--0 and SiO J=2--1 with the IRAM Plateau de Bure interferometer. The 3 mm data, with a resolution of ~5" X 4", displays a unresolved continuum source at the peak of the extended 1.2 mm emission and closely associated with the ultra-compact HII region. The H13CO+ map traces the central condensation in good agreement with previous NH_3 maps of Zheng et al. (1985). However, the velocity field of this central condensation, which was previously thought to arise in a rapidly rotating structure, is better explained in terms of the dense and compact component of a bipolar outflow. This interpretation is confirmed by SiO and CO observations of the full region. In fact, our new SiO data unveils the presence of multiple (at least 4) outflows in the region. In particular, there is an important center of outflow activity in the region at about 1' north of the UCHII region. Indeed the different outflows are related to different members of the Onsala 1 cluster. The data presented here support a scenario in which the phases of massive star formation begin much later in the evolution of a cluster and/or UCHII region last for much longer than 10^5 yrs.

description: A Quantum Phase Transition (QPT) in a simple model that describes the coexistence of atoms and diatomic molecules is studied. The model, that is briefly discussed, presents a second order ground state phase transition in the thermodynamic (or large particle number) limit, changing from a molecular condensate in one phase to an equilibrium of diatomic molecules-atoms in coexistence in the other one. Usual markers for this phase transition are the ground state energy and the expectation value of the number of atoms (or, alternatvely, the number of molecules) in the ground state. In this work, other markers for the QPT as the Inverse Participation Ratio (IPR) and, particularly, the Rényi entropy are analysed and proposed as QPT markers. Both magnitudes present abrupt changes at the critical point of the QPT.

description: We present the results of ATCA HI line and 20-cm radio continuum observations of the galaxy Quartet NGC 6845. The HI emission extends over all four galaxies but can only be associated clearly with the two spiral galaxies, NGC 6845A and B, which show signs of strong tidal interaction. We derive a total HI mass of at least 1.8 x 10^10 Msun, most of which is associated with NGC 6845A, the largest galaxy of the group. We investigate the tidal interaction between NGC 6845A and B by studying the kinematics of distinct HI components and their relation to the known HII regions. No HI emission is detected from the two lenticular galaxies, NGC 6845C and D. A previously uncatalogued dwarf galaxy, ATCA J2001-4659, was detected 4.4' NE from NGC 6845B and has an HI mass of about 5 x 10^8 Msun. No HI bridge is visible between the group and its newly detected companion. Extended 20-cm radio continuum emission is detected in NGC 6845A and B as well as in the tidal bridge between the two galaxies. We derive star formation rates of 15 to 40 Msun/yr.

description: Proof-of-Work (PoW) systems face critical challenges, including excessive energy consumption and the centralization of mining power among entities with expensive hardware. Static mining pools exacerbate these issues by reducing competition and undermining the decentralized nature of blockchain networks, leading to economic inequality and inefficiencies in resource allocation. Their reliance on centralized pool managers further introduces vulnerabilities by creating a system that fails to ensure secure and fair reward distribution. This paper introduces a novel Collaborative Proof-of-Work (CPoW) mining approach designed to enhance efficiency and fairness in the Ethereum network. We propose a dynamic mining pool formation protocol that enables miners to collaborate based on their computational capabilities, ensuring fair and secure reward distribution by incorporating mechanisms to accurately verify and allocate rewards. By addressing the centralization and energy inefficiencies of traditional mining, this research contributes to a more sustainable blockchain ecosystem.

description: Observation time is the key parameter for improving the precision of measurements of gravitational quantum states of particles levitating above a reflecting surface. We propose a new method of long confinement in such states of atoms, anti-atoms, neutrons and other particles possessing a magnetic moment. The Earth gravitational field and a reflecting mirror confine particles in the vertical direction. The magnetic field originating from electric current passing through a vertical wire confines particles in the radial direction. Under appropriate conditions, motions along these two directions are decoupled to a high degree. We estimate characteristic parameters of the problem, and list possible systematic effects that limit storage times due to the coupling of the two motions. In the limit of low particle velocities and magnetic fields, precise control of the particle motion and long storage times in the trap can provide ideal conditions for both gravitational, optical and hyperfine spectroscopy: for the sensitive verification of the equivalence principle for antihydrogen atoms; for increasing the accuracy of optical and hyperfine spectroscopy of atoms and antiatoms; for improving constraints on extra fundamental interactions from experiments with neutrons, atoms and antiatoms.

description: The contribution of radiative processes to $p_\perp$-broadening of fast partons in a quark-gluon plasma is investigated. Calculations are performed beyond the soft gluon approximation. It is shown that the radiative correction to $\langle p_{\perp}^2\rangle$ for conditions of heavy ion collisions at RHIC and LHC is negative and can be comparable in absolute value with the nonradiative contribution. This prediction differs radically from the essentially positive contribution of radiative processes to $p_{\perp}$-broadening, which was predicted earlier in the literature.

description: We aimed to report the results of fundus photography ophthalmic examinations among older adults in a rural community in South Korea. We used data from the Korean Social Life, Health, and Aging Project cohort study, which was designed to examine the entire population of individuals aged 60 years or older and their spouses living in a rural Village K of Ganghwa Island, South Korea. At baseline, a total of 860 people was targeted as the study population. From December 2011 to January 2019, five health examinations were conducted, including baseline and follow-up tests. During the fifth wave of the study, we performed fundus photography to assess eye health. Ophthalmic and physical examinations were conducted for 387 people who participated in the fifth wave by trained researchers. Systemic factors were evaluated via blood and diagnostic tests. After excluding eight people who did not undergo follow-up fundoscopy, a total of 379 participants was included for analysis. We classified the participants into two groups with either no (zero) or one or more suspicious ophthalmic diseases. The abnormalities included media opacity, suspected glaucoma, and suspicion of retinal disease as diagnosed by a trained specialist. We further categorized ophthalmic conditions as clinically insignificant, follow-up needed, semi-urgent, and urgent conditions. We included 379 participants, of which 225 (59.4%) were women. The mean age of the participants was 76.4 ± 6.2 years. Among all participants, 81% (n=307) had one or more abnormalities on fundus screening. Older age, living alone, high blood pressure, and high fasting insulin were associated with an increased risk of having ≥ one eye disease. In terms of triage, 3.7% (n= 14) of the observed conditions were urgent, and 25.9% (n= 98) were semi-urgent. Therefore, we documented fundoscopy results among the elderly population in a rural community in South Korea. Elderly people living alone were more likely to have eye disease. Policies to improve eye health are needed to prevent vision loss in this population.

description: We investigated realistic neutron stars in axion $R^{2}$ gravity. The coupling between curvature and axion field $ϕ$ is assumed in the simple form $\sim R^2ϕ$. For the axion mass in the range $m_{a}\sim 10^{-11}-10^{-10}$ eV the solitonic core within neutron star and corresponding halo with size $\sim 100$ km can exist. Therefore the effective contribution of $R^2$ term grows inside the star and it leads to change of star parameters (namely, mass and radius). We obtained the increase of star mass independent from central density for wide range of masses. Therefore, maximal possible mass for given equation of state grows. At the same time, the star radius increases not so considerably in comparison with GR. {Hence, our model may predict possible existence of supermassive compact stars with masses $M\sim 2.2-2.3M_\odot$ and radii $R_{s}\sim 11$ km for realistic equation of state (we considered APR equation of state). In General Relativity one can obtain neutron stars with such characteristics only for unrealistic, extremely stiff equations of state.} Note that this increase of mass occurs due to change of solution for scalar curvature outside the star. In GR curvature drops to zero on star surface where $ρ=p=0$. In the model under consideration the scalar curvature dumps more slowly in comparison with vacuum $R^2$ gravity due to axion "galo" around the star.

description: Despite the growing number of pregnant women engaging in outdoor adventure activities, very few studies have explored pregnancy or the specific needs and challenges of pregnant women in tourism research. To fill this gap in the literature, we examine the participation of pregnant women in adventure tourism through the theoretical lens of liminality. Conceptualising pregnancy as a liminal stage in which women are ‘suspended’ between two statuses, opens diverse possibilities to delve into women’s experiences of embodiment, bodily image and control. In this sense, pregnancy is understood as an ‘internal change’, which adds specific challenges to women’s practice of adventure tourism, including bodily changes and different perceptions of risk-taking. Similarly, the context of adventure tourism provides an ideal space to reflect on liminal transitions and the ‘outside changes’ that pregnant women go through in the predominantly masculinised spaces that characterise this tourism segment. Semi-structured interviews were conducted with 35 Mexican women who actively pursue adventure tourism and who had engaged in these activities during at least one pregnancy. The analysis indicates the importance of norms and social expectations experienced by pregnant women when doing adventure tourism. The concept of the ‘rhizomatic body’ proved to be a valuable tool when looking at the social taboos, prohibitions and rules that apply to pregnant women in specific sociocultural contexts (in this case, Mexico). By reframing and reconceptualising pregnant women and their practice of adventure activities, the social construction of pregnancy is elucidated. Finally, the study contributes to the understanding of alternative models and experiences of being a woman in gendered spaces, while shedding light on relevant behavioural patterns among pregnant tourists and the sociocultural impacts of these patterns.

description: Daylight plays a major role in the wake/sleep cycle in humans. Indeed, the wake/sleep system stems from biological systems that follow a circadian rhythm determined by the light/dark alternation. The oscillations can be modeled by the higher order non-linearity van der Pol -type equation driven by a term that mimics the light cycle. In this work noise in the illumination is introduced to investigate its effect on the human circadian cycle. It is found that the presence of noise is detrimental for the sleep/wake rhythm, except for some special values for which it may favor regular oscillations. Depending for system parameters, noise induces regularities, such as stochastic resonance: if the natural light is turned off, it emerges that there is an optimal value of intensity noise which most deteriorates the regularity of the cycle, it is the phenomenon of anti-coherent resonance. Also, the phenomenon of stochastic resonance occurs: in the presence of the drive of natural light, there is an optimal noise intensity which improves the evolution of the wake / sleep system. However, there is a critical value of the noise beyond which the system becomes chaotic; indeed, for sufficiently high noise levels (how high depends upon the parameter of the system), the sleep/wake cycle evolves in a random and unpredictable manner, for whatever parameters of the external light.

description: We present a systematic approach for determining the optimal actuator location for separation control from input-output response data, gathered from numerical simulations or physical experiments. The Eigensystem Realization Algorithm is used to extract state-space descriptions from the response data associated with a candidate set of actuator locations. These system realizations are then used to determine the actuator location among the set that can drive the system output to an arbitrary value with minimal control effort. The solution of the corresponding minimum energy optimal control problem is evaluated by computing the generalized output controllability Gramian. We use the method to analyze high-fidelity numerical simulation data of the lift and separation-angle responses to a pulse of localized body-force actuation from six distinct locations on the upper surface of a NACA 65(1)-412 airfoil. We find that the optimal location for controlling lift is different from the optimal location for controlling separation angle. In order to explain the physical mechanisms underlying these differences, we conduct controllability analyses of the flowfield by leveraging the dynamic mode decomposition with control algorithm. These modal analyses of flowfield response data reveal that excitation of coherent structures in the wake benefit lift control; whereas, excitation of coherent structures in the shear layer benefit separation-angle control.

description: Prior to the commencement of this study, all parties involved (i.e. CAC, the author, her supervisor and UCT) signed a non-disclosure agreement, which granted the author permission to use the data concerned, subject to confidentiality requirements. Ethical clearance for the research was also obtained from the UCT Ethics Committee. Following this, the PGDA Programme Coordinator at CA Connect ("CAC") sent the author several spreadsheets containing the relevant information applicable to the CAC PGDA classes of 2015, 2016 and 2017. The information received from CAC consisted of details entered into the online application system by students when applying for the programme (which had been independently validated by CAC for all accepted students); demographic data gathered at the time of enrolment; the final marks spreadsheet for each academic year, indicating students’ results in each of the four core subjects after the outcome of supplementary exams had been taken into account; and an analysis of the ITC results of students who had successfully passed PGDA. Working backwards from students for whom the marks spreadsheet indicated final PGDA outcomes (i.e. eliminating those students who were either not eligible for final exams in accordance with the programme rules or who had dropped out during the year for some other reason), relevant information was compiled for each student in each year, using their unique, numeric student number as a reference point. Where missing data points were identified for certain students, the author manually retrieved this information from CAC’s online application records, where possible. The three years were then combined into a single spreadsheet. Any identifying particulars (such, as name, surname and student number) were then deleted from the dataset and each data point was instead allocated a unique ID number for the purposes of this research.

description: We develop an exact generalized Bogoliubov transformation for the spin 3/2 Hubbard model with large anti-Hunds rule coupling near half filling. Since our transformation is unitary, we can thereafter employ standard approximate mean field theory methods in the full Hilbert space to analyze the doped Mott insulator, in contrast to a conventional approach based on truncated Hilbert spaces complemented with hard core constraints. The ground state at exactly half filling is an insulating (Mott) singlet, and according to our analysis a non-Fermi liquid order parameter $ Δ$ usually associated with extended s-wave superconductivity, will appear self-consistently as soon as a finite density $ n $ holes are introduced. The non-Fermi liquid behavior is a consequence of the nonlinear nature of the unitary transformation mapping the Mott singlet state to a Fock vacuum which introduces anomalous terms such as $Δn$ in the effective Lagrangian. Our analysis uses an approach that generalizes readily to multi-band Hubbard models and could provide a mechanism whereby a non-Fermi liquid order parameter proportional to density is developed in Mott insulators with locally entangled ground states. For more complicated systems, such an order parameter could coexist naturally with a variety of other order parameters.

description: High-resolution observations of the solar photosphere have recently revealed the presence of elongated filamentary bright structures inside sunspot umbrae. These features, which have been called umbral filaments (UFs), differ in morphology, evolution, and magnetic configuration from light bridges that are usually observed to intrude in sunspots. To study an UF observed in the leading sunspot of active region NOAA 12529, we have analyzed spectro-polarimetric observations taken in the photosphere with the spectropolarimeter (SP) aboard the Hinode satellite. High-resolution observations in the upper chromosphere and transition region taken with the IRIS telescope and observations acquired by SDO/HMI and SDO/AIA have been used to complement the spectro-polarimetric analysis. The results obtained from the inversion of the Hinode/SP measurements allow us to discard the hypothesis that UFs are a kind of light bridge. In fact, we find no field-free or low-field strength region cospatial to the observed UF. In contrast, we detect in the structure Stokes profiles that indicate the presence of strong horizontal fields, larger than 2500 G. Furthermore, a significant portion of the UF has opposite polarity with respect to the hosting umbra. In the upper atmospheric layers, we observe filaments being cospatial to the UF in the photosphere. We interpret these findings as suggesting that the UF could be the photospheric manifestation of a flux rope hanging above the sunspot, which triggers the formation of penumbral-like filaments within the umbra via magneto-convection.

Subjects: subject: Artificial intelligence

description: In the coming years, the impact of Artificial Intelligence (AI) will be keenly felt, in both, our personal and professional lives. Given the pace and scale of developments in this field, it is imperative to explore AI research and potential applications. Kohonen’s Self-Organising Maps is an algorithm used to improve a machine’s performance in pattern recognition problems. The algorithm is especially capable of clustering and visualising complex high-dimensional data and can potentially be applied to solve many complex real-world problems. The aim of this thesis is to provide an in-depth study of Kohonen’s algorithm, and present insights of its properties, by implementing a complete and functional model. As part of this project, an extensive literature review on Kohonen networks was conducted first; and a brief background on its relevance to society, the technical structure, and the variables and formulas are presented. The scope, aims and objectives of the project are then defined in detail, highlighting the key differences that make Kohonen networks unique compared to other available models. Subsequently, the project follows a design methodology, employing identified technologies to build a model, before presenting a comprehensive description of how each component of the final implementation was realised and tested. The results of the project are then presented to provide answers to the formulated problem, before evaluating the project, and discussing its strengths, weaknesses, and the general learning points.

description: Underwater noise pollution from the installation of offshore wind turbine foundations and the detonation of unexploded ordnance (UXO) is recognised as an issue of growing concern by UK regulators and policymakers. Marine mammals, fish and invertebrate species can be adversely affected by exposure to noise from these activities. Some of these species are protected under UK law, and in order to issue a license authorising these activities it needs to be shown that there is no satisfactory alternative to the activity. However, for both pile-driving and UXO, technologies are available which reduce the amount of noise emitted at source (noise abatement). Such technologies are being routinely deployed in other parts of the North Sea in order to reduce the risk of impact on marine life, particularly marine mammals. The aim of the workshop was to explore the technical feasibility of applying noise abatement measurements to offshore windfarm construction and UXO detonation to improve the quality of the acoustic habitat in UK seas. Drawing on expertise developed by operators implementing noise abatement measures elsewhere in the North Sea, the workshop considered the technologies available and their benefits, and assessed what technical challenges there may be to implementation in UK waters. As well as technical input, representatives from industry, non-governmental organisations, government agencies, and Statutory Nature Conservation Bodies offered their perspectives on the issue, and a structured break-out session allowed time for more focused groups to discuss ways forward.
