A review of critical pedagogies in health and social care: Findings from a ‘best fit’ framework synthesis
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Social determinants of health

description: Although recent research has highlighted the importance of understanding the structural social processes through which stigma is produced and maintained, educational approaches to stigma-reduction have not yet engaged with this concept. Recognising that critical pedagogies have been used in other contexts to help learners better understand and challenge structural social processes of marginalisation, we conducted a review of educational interventions that were informed by critical pedagogies and delivered within settings of health and social care. A systematic search was performed on academic and grey literature databases between January 1970 and 17 May 2017 to identify all literature reporting on the learning outcomes of educational interventions informed by frameworks of critical consciousness development. Articles were selected following a two-stage screening process and an assessment of methodological quality. Of the 9,674 articles identified from the systematic search, 33 were found to satisfy the inclusion criteria and were of sufficient quality to be considered within this review. Two major findings emerged from the analysis of interventional studies. Firstly, it was found that learners consistently articulated a sociostructural understanding of oppressive social relations and their position within it, based upon an understanding of their own group identity. Secondly, and despite the sociostructural content of reflection, individual actions tended to focus on the modification of interpersonal interactions. Although educational interventions informed by a critical pedagogy appear to support a structural analysis of social marginalisation or disadvantage, there is limited evidence to suggest how these structural processes might be challenged following this analysis.

description: In this paper we present a formal computational framework for modeling manipulation actions. The introduced formalism leads to semantics of manipulation action and has applications to both observing and understanding human manipulation actions as well as executing them with a robotic mechanism (e.g. a humanoid robot). It is based on a Combinatory Categorial Grammar. The goal of the introduced framework is to: (1) represent manipulation actions with both syntax and semantic parts, where the semantic part employs $λ$-calculus; (2) enable a probabilistic semantic parsing schema to learn the $λ$-calculus representation of manipulation action from an annotated action corpus of videos; (3) use (1) and (2) to develop a system that visually observes manipulation actions and understands their meaning while it can reason beyond observations using propositional logic and axiom schemata. The experiments conducted on a public available large manipulation action dataset validate the theoretical framework and our implementation.

A realist review of infant feeding counselling to increase exclusive breastfeeding by HIV-positive women in sub Saharan-Africa: What works for whom and in what contexts
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Community child health

description: Background: The most recent World Health Organization (WHO) guidelines on Human Immunodeficiency Virus (HIV) and infant feeding promotes exclusive breastfeeding (EBF) in resource limited settings for the prevention of mother to child transmission (PMTCT) of HIV. Literature reveals poor uptake of WHO feeding guidelines, with mixed feeding being a regular practice. In light of the limited success in EBF promotion, a realist review was conducted, analysing the use of feeding counselling to increase exclusive breastfeeding by HIV-positive women in sub Saharan-Africa, where the majority of HIV childhood infections occur. We considered what mechanisms were at play, for whom and in what circumstances they led to exclusive breastfeeding. Methods: Because infant feeding counselling is a complex social intervention with a non-linear causal pathway for preventing mother to child HIV transmission, a realist methodology was chosen for this study. Using Pawson's five stage sequence for conducting realist reviews, the results are presented as a set of identified and refined context-mechanism-outcome (CMO) configurations. These CMO configurations were used to show how particular outcomes occurred in specific contexts due to a generative mechanism and were developed through identifying a review question and program theory, searching for primary studies, quality appraisal, data extraction and data synthesis. Results: From an initial 1010 papers, 27 papers met the inclusion criteria and were used to refine the program theory. Exclusive breastfeeding occurred when a woman was motivated regarding motherhood, had correct learning and understanding about infant feeding practices through counselling, no fear of breastfeeding or the impact of opposing feeding related cultural beliefs, and the support from others to be assertive about their feeding choices when faced with pressure to mix-feed. An additional CMO configuration was added during the refinement of the program theory identifying that mothers needed to not just understand but also prioritize EBF advice over cultural beliefs and stigma. Conclusion: The intended audience for this review are researchers and health care workers in PMTCT, particularly sub-Saharan Africa, who may benefit from the work that has been done to identify contexts for the success and failures of EBF.
Characteristic distribution of finite-time Lyapunov exponents for chimera states

Subjects: subject: Chaotic Dynamics (nlin.CD)

description: It is shown that probability densities of finite-time Lyapunov exponents, corresponding to chimera states, have a characteristic shape. Such distributions could be used as a signature of chimera states, particularly in systems for which the phases of all the oscillators cannot be measured directly. In such cases, the characteristic distribution may be obtained indirectly, via embedding techniques, thus making it possible to detect chimera states in systems where they could otherwise exist, unnoticed.
Crystallisation of soft matter under confinement at interfaces and in wedges

description: The surface freezing and surface melting transitions exhibited by a model two-dimensional soft matter system is studied. The behaviour when confined within a wedge is also considered. The system consists of particles interacting via a soft purely repulsive pair potential. Density functional theory (DFT) is used to calculate density profiles and thermodynamic quantities. The external potential due to the confining walls is modelled via a hard-wall with an additional repulsive Yukawa potential. The surface phase behaviour depends on the range and strength of this repulsion: When the repulsion strength is weak, the wall promotes freezing at the surface of the wall. The thickness of this frozen layer grows logarithmically as the bulk liquid-solid phase coexistence is approached. Our mean-field DFT predicts that this crystalline layer at the wall must be nucleated (i.e. there is a free energy barrier) and its formation is necessarily a first-order transition, referred to as `prefreezing', by analogy with the prewetting transition. However, in contrast to the latter, prefreezing cannot terminate in a critical point, since the phase transition involves a change in symmetry. If the wall-fluid interaction is sufficiently long ranged and the repulsion is strong enough, surface melting can instead occur. Then the interface between the wall and the bulk crystalline solid becomes wet by the liquid phase as the chemical potential is decreased towards the value at liquid-solid coexistence. It is observed that the finite thickness fluid film at the wall has a broken translational symmetry due to its proximity to the bulk crystal and so the nucleation of the wetting film can be either first-order or continuous. Our mean-field theory predicts that for certain wall potentials there is a premelting critical point analogous to the surface critical point for the prewetting transition. In a wedge...

A population health approach in education to support children's early development: A Critical Interpretive Synthesis
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Community child health

description: The primary objective of this review is to investigate what is currently known about early childhood education planning, population health models and their relation to children's development. A systematic review using the Critical Interpretive Synthesis method was undertaken, guided by a preliminary research question, "How can a population heath approach be applied to educational planning to support children's early development?" which acted as a compass and guide throughout the process. The initial search yielded 20,122 results, of which 42 were included in the review. Four synthetic constructs emerged (1) Elements of population health models exist within communities and can help improve outcomes for more children, (2) Inter-disciplinary collaboration and partnerships possess unique opportunities to influence children's development, (3) Children's development can be influenced at a variety of levels, and (4) System change requires a range of drivers and supports. Within education, there are several models which are used to improve outcomes for children and families. Although a population health approach to planning does not explicitly exist, the results from this review indicate that it would indeed be plausible to adapt the population health approach to sites and schools, and that doing so would be advantageous for children's development. However, implementing such an approach requires more than desire for change and demands system changes and supports. A protocol for the review was published on the International Prospective Register of Systematic Reviews (PROSPERO), registration number CRD42018098835 on 31st July 2018.

description: We report on an analysis of the impact of available experimental data on hard processes in proton-lead collisions during Run I at the Large Hadron Collider on nuclear modifications of parton distribution functions. Our analysis is restricted to the EPS09 and DSSZ global fits. The measurements that we consider comprise production of massive gauge bosons, jets, charged hadrons and pions. This is the first time a study of nuclear PDFs includes this number of different observables. The goal of the paper is twofold: i) checking the description of the data by nPDFs, as well as the relevance of these nuclear effects, in a quantitative manner; ii) testing the constraining power of these data in eventual global fits, for which we use the Bayesian reweighting technique. We find an overall good, even too good, description of the data, indicating that more constraining power would require a better control over the systematic uncertainties and/or the proper proton-proton reference from LHC Run II. Some of the observables, however, show sizable tension with specific choices of proton and nuclear PDFs. We also comment on the corresponding improvements on the theoretical treatment.

An association of serum ALT with elevated blood pressure in senior adults: A case control study
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Aged health care

description: Hypertension is a major risk factor for cardiovascular diseases in China; hence, identifying good serum markers might provide cost benefits in terms of reducing morbidity rates. In this population-based case-control study, participants were recruited from five districts in Hunan province, and 416 cases were matched with an equal number of controls. Markers related to elevated blood pressure were assessed: Body Mass Index, total cholesterol, triglycerides, fasting blood glucose, and creatinine. Three potential serum markers homocysteine (HCY), C-reactive protein (CRP), and alanine aminotransferase (ALT) were dichotomized as normal or high level. Binary logistic regression was used to determine odds ratios (ORs) and 95% confidence intervals (CIs). The findings showed that ALT is a powerful serum marker for predicting high risk of high blood pressure with OR = 2.94, 95% CI (1.44–6.02), while there were no significant differences between cases and controls for HCY and CRP. Additionally, it seems likely that high concentrations of HCY conferred a protective effect against elevated blood pressure. When adjusted for sex, ORs for hypertensive females were nearly five times higher than for hypertensive males (OR = 4.34, 95% CI = 1.17–16.04). The study strongly supports findings showing ALT is a potential indicator for patients with hypertension.

description: For the study of symmetry-breaking phenomena in neuronal networks, simplified versions of the FitzHugh-Nagumo model are widely used. In this paper, these phenomena are investigated in a network of FitzHugh-Nagumo oscillators taken in the form of the original model and it is found that it exhibits diverse partial synchronization patterns that are unobserved in the networks with simplified models. Apart from the classical chimera, we report a new type of chimera pattern whose incoherent clusters are characterized by spatial random swings among a few fixed periodic attractors. Another peculiar hybrid state is found that combines the features of this chimera state and a solitary state such that the main coherent cluster is interspersed with some nodes with identical solitary dynamics. In addition, oscillation death including chimera death emerges in this network. A reduced model of the network is derived to study oscillation death, which helps explaining the transition from spatial chaos to oscillation death via the chimera state with a solitary state. This study deepens our understanding of chimera patterns in neuronal networks.
A model for (re)building consumer trust in the food system

Subjects: Public health nutrition

description: The article presents a best practice model that can be utilized by food system actors to assist with (re) building trust in the food system, before, during and after a food incident defined as 'any situation within the food supply chain where there is a risk or potential risk of illness or confirmed illness or injury associated with the consumption of a food or foods' (Commonwealth of Australia. National Food Incident Response Protocol. Commonwealth of Australia, Canberra, 2012). Interviews were undertaken with 105 actors working within the media, food industry and food regulatory settings across Australia, New Zealand (NZ) and the United Kingdom (UK). Interview data produced strategy statements, which indicated participant views on how to (re)build consumer trust in the food system. These included: (i) be transparent, (ii) have protocols and procedures in place, (iii) be credible, (iv) be proactive, (v) put consumers first, (vi) collaborate with stakeholders, (vii) be consistent, (viii) educate stakeholders and consumers, (ix) build your reputation and (x) keep your promises. A survey was designed to enable participants to indicate their agreement/disagreement with the ideas, rate their importance and provide further comment. The five strategies considered key to (re)building consumer trust were used to develop a model demonstrating best practice strategies for (re)building consumer trust in the food system before, during and after a food incident. In a world where the food system is increasingly complex, strategies for (re)building and fostering consumer trust are important. This study offers a model to do so which is derived from the views and experiences of actors working across the food industry, food regulation and the media.

Alcohol and Flourishing for Australian Women in Midlife: A Qualitative Study of Negotiating (Un)Happiness
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Social determinants of health

description: This article responds to calls for empirically grounded and critically analytical research on the sociology of happiness. We explore how 35 Australian women in midlife (45–64 years) navigate alcohol use in the context of gendered lifecourses. In response to emerging themes around happiness in and through alcohol consumption during inductive analysis, data were re-analysed using neo-Aristotlean notions of flourishing. This illuminated alcohol consumption for women in midlife vis-á-vis moment-in-time pleasure, lifecourse happiness and management of gendered constraints. Drawing on Ahmed’s concepts of ‘affective economies’ and ‘happiness and unhappiness archives’ we contemporise Aristotle’s notion of flourishing and argue that changing structures of feeling for women in midlife give rise to differing emotions that attach to alcohol use. Understanding the affective reasons for alcohol consumption among this population provides new avenues to think about how alcohol consumption is purposed by women to make and make do with (un)happiness during midlife.

Alcohol and breast cancer risk: Middle-aged women's logic and recommendations for reducing consumption in Australia
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Preventative health care

description: Background :We aimed to understand the factors shaping alcohol consumption patterns in middle-aged women (45-64), and to identify participant-driven population- and policy-level strategies that may be used to addresses alcohol consumption and reduce breast cancer risk. Methods: Semi-structured interviews (n = 35) were conducted with 'middle-aged' women conversant in English and living in South Australia with no history of breast cancer diagnosis. Data were deductively coded using a co-developed framework including variables relevant to our study objectives. Women were asked about their current level of awareness of the association between alcohol and breast cancer risk, and their personal recommendations for how to decrease consumption in middle-aged Australian women. Results: Women discussed their previous efforts to decrease consumption, which we drew on to identify preliminary recommendations for consumption reduction. We identified a low level of awareness of alcohol and breast cancer risk, and confusion related to alcohol as a risk for breast cancer, but not always causing breast cancer. Participants suggested that education and awareness, through various means, may help to reduce consumption. Conclusions: Participants' description of strategies used to reduce their own consumption lead us to suggest that campaigns might focus on the more salient and immediate effects of alcohol (e.g. on physical appearance and mental health) rather than longer-term consequences. Critical considerations for messaging include addressing the personal, physical and social pleasures that alcohol provides, and how these may differ across socio-demographics.
Parallel search algorithm for finding the closest object in a collection of polygonal models

Publisher: name: Zenodo
Year: 2023

description: In this paper, we consider the problem of finding an element of a collection of polygonal models that is closest to a given object using parallel computing. Options for parallelizing the solution to this problem are proposed, with static and dynamic load balancing, which made it possible to significantly speed up the search process. The developed algorithm was implemented in the Python programming language using the MPI for Python library, which supports parallel computing, and tested on a collection of several thousand models on a local machine and on the IBM Polus high-performance computing system. The results of computational experiments have shown that the developed algorithm significantly outperforms the sequential search for the closest object in terms of computation speed. The algorithm proposed in this paper can be used in various fields, such as computer graphics, computer vision, robotics, and others.

description: We report calculations of the surface tension of the water-air interface using ab initio molecular dynamics (AIMD) simulations. We investigate the simulation cell size dependence of the surface tension of water from force field molecular dynamics (MD) simulations, which show that the calculated surface tension increases with increasing simulation cell size, thereby illustrating that a correction for finite size effects is required for the small system used in the AIMD simulation. The AIMD simulations reveal that the double-ξ basis set overestimates the experimentally measured surface tension due to the Pulay stress, while the triple and quadruple-ξ basis sets give similar results. We further demonstrate that the van der Waals corrections critically affect the surface tension. AIMD simulations without the van der Waals correction substantially underestimate the surface tension, while van der Waals correction with the Grimme's D2 technique results in the value for the surface tension that is too high. The Grimme's D3 van der Waals correction provides a surface tension close to the experimental value. Whereas the specific choices for the van der Waals correction and basis sets critically affect the calculated surface tension, the surface tension is remarkably insensitive to the details of the exchange and correlation functionals, which highlights the impact of long-range interactions on the surface tension. These simulated values provide important benchmarks, both for improving van der Waals corrections, and AIMD simulations of aqueous interfaces.

A critical food system program in South Australia and the effects on consumer knowledge and attitudes
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Public health nutrition

description: Issue addressed: This study investigated the effects of food system literacy on knowledge and attitudes of food consumers. Methods: A 2-week online course critically discussed the food system through three lenses of environmental sustainability, equity and health. Participants were randomly allocated into one Control and two Intervention groups (A & B). Data collection was by online questionnaire pre- and postintervention, addressing self-perceived food system knowledge, attitudes towards food purchasing behaviours, demographic characteristics and course evaluation. Differences in knowledge and attitude scores between Control and Intervention groups were assessed. Subjects were staff and students of Flinders University in South Australia. Results: Forty-seven participants completed the course. The completion rate was 71.2%. Knowledge about the food system improved significantly for both Intervention groups when compared to the Control group (P ≤ 0.001). Although attitudes towards food purchasing behaviours also improved significantly for both Intervention groups (P < 0.001 and P = 0.005 for Interventions A and B respectively), the improvements were not significant when compared to the Control group (P = 0.065 and P = 0.43 for Interventions A and B respectively). The online methodology received positive feedback from participants. Conclusion: This 2-week online food system course showed that the pedagogy was appropriate and successful in improving self-perceived knowledge and attitudes towards food consumption. So what?: It provides encouraging indications of the potential of food system literacy to empower citizens to make healthier as well as, more environmentally and socially sustainable food choices.

description: Solid-state modulation of 2-dimensional electron gases (2DEGs) with extreme (~3.3 x 1014 cm-2) densities corresponding to 1/2 electron per interface unit cell at complex oxide heterointerfaces (such as SrTiO3/GdTiO3 or SrTiO3/SmTiO3) is challenging because it requires enormous gate capacitances. One way to achieve large gate capacitances is by geometrical capacitance enhancement in fin structures. In this work, we fabricate both Au-gated planar field effect transistors (FETs) and Fin-FETs with varying fin-widths on 60nm SrTiO3/5nm SmTiO3 thin films grown by hybrid molecular beam epitaxy (hMBE). We find that the FinFETs exhibit higher gate capacitance compared to planar FETs. By scaling down the SrTiO3/SmTiO3 fin widths, we demonstrate further gate capacitance enhancement, almost twice compared to the planar FETs. In the FinFETs with narrowest fin-widths, we demonstrate a record 2DEG electron concentration modulation of ~2.4 x 1014 cm-2.

We achieve this by creating a controlled number of initial seed excitations. Greater insight into the avalanche mechanism is obtained from an analysis of the full counting distributions. We also present simple mathematical models and numerical simulations of the excitation avalanches that agree well with our experimental results.

description: Background Exercise is the recommended first-line therapy for a degenerative meniscal tear (DMT). Despite this, knee pain attributed to DMTs are a common presentation to specialist orthopaedic clinics. In the primary care setting, the general practitioner (GP) plays a central role in managing patients with knee pain, but to date their perspective has not been explored in relation to DMTs. This study explored GPs’ experiences of managing people with knee pain attributed to a DMT. Methods A qualitative research design was adopted and practices in the South and Mid-West of Ireland were contacted via recruitment emails circulated through professional and research networks. Interested GPs contacted the researchers via email, and purposive and snowball sampling was used for recruitment. Semi-structured interviews were conducted online or over the telephone. Interviews were digitally recorded and transcribed. Data was analysed using an inductive approach to thematic analysis. Ethical approval was granted by the Irish College of General Practitioners (ICGP_REC_21_0031). Results Seventeen semi-structured one-on-one interviews were conducted. Three main themes were identified with related subthemes: (1) GPs’ experiences of relational aspects of care, (2) GP beliefs about what constitutes best care for patients with a DMT, and (3) how GP practice is enacted within the current healthcare setting. GPs described the challenge of maintaining a strong clinical alliance, while managing perceived patient expectations of a ‘quick fix’ and advanced imaging. They reported slowing down clinical decisions and feeling ‘stuck’ with limited options when conservative treatment had failed. GPs believed that exercise should be the core treatment for DMTs and emphasised engaging patients in an active approach to recovery. Some GPs believed arthroscopy had a role in circumstances where patients didn’t improve with physiotherapy. Limited access to public physiotherapy and orthopaedic services hampered GPs’ management plans and negatively impacted patient outcomes. Conclusions GP beliefs around what constitutes best care for a DMT generally aligned with the evidence base. Nonetheless, there was sometimes tension between these beliefs and the patient’s own treatment expectations.The ability to enact their beliefs was hampered by limited access to conservative management options, sometimes leading to early escalation of care
Where is the beat : introducing 'AV-PhonemeBeatSync', a multimodal singing dataset aiming at understanding coarticulation and rhythm in singing

description: Singing, the vocal production of musical tones is a key element in music. It plays a central role in the emotions perceived while listening to a musical piece, and has been present in human culture since antiquity, acting as a way to transmit information such as stories, rituals or tales from the past. Being able to sing well is considered as a valuable skill to have, and singing has shown benefits in mental and physical health. A distinctive area of Music Information Retrieval is dedicated to the analysis and synthesis of singing. Research in this domain focuses notably on understanding the singing processus, assessing performance quality, or generating automatic singing content.
 While most of the approaches now uses extensive machine learning techniques, datasets are lacking, and there is none containing annotated audiovisual singing performances and none containing clear beat annotations. Previous research has been done on analyzing a singing performance and giving feedback, but none of them tried to understand where the performers line the syllables with their percep-tion of the beat, and where the emphasis is placed.
 In this Master Thesis, we present a new multimodal dataset : AV_PhonemeBeatSync, aiming at providing new annotated data to propel various research on singing anal-ysis and synthesis. A brief analysis is conducted on the gathered data, and we find that performers, when having to sing a syllable, concentrate their attention on the vowels and disregard the consonants, regardless of their singing experience.
 AV_PhonemeBeatSync contains valuable data that is worth mining, and could be used to train and evaluate neural networks aiming at visually understanding the coarticulation phenomenon, and the relationship between lyrics and rhythm.

description: We analyze archival Chandra HRC observations of the ultra luminous accreting pulsar M82-X2 (NuSTAR J095551+6940.8), and determine an upper limit of $< 1.7\times 10^{38}$~erg/s to its luminosity at an epoch at which it was undetected. Combined with other recent measurements, this confirms that the source X-ray emission has been highly variable during the last 15 years, ranging from a maximum of $10^{40}$ erg/s through intermediate values $\sim$ a few $\times 10^{39}$ erg/s, and down to a minimum that must be below the current detection threshold $\sim (2-3) \times 10^{38}$ erg/s . We interpret these results by means of a magnetically-threaded disk model: when at peak luminosity, the neutron star (NS) is close to spin equilibrium, its inner disk edge r_m ~ 10^8 cm is approximately half the corotation radius r_{co}, and radiation pressure dominates the disk out to r_{tr} ~ 10^9 cm. In the radiation pressure-dominated regime, r_m grows very slowly as the mass inflow rate drops: as a result, r_m < r_{co} remains valid until the mass accretion rate becomes ~ the Eddington accretion rate, allowing a wide range of accretion luminosities to the NS. Once the mass accretion rate is below Eddington, accretion onto the NS is inhibited because r_m > r_{co}, and the source luminosity is expected to drop by a large factor. We conclude that a magnetically threaded, radiation pressure-dominated disk, around a highly magnetized NS (B~10^{13} G) offers the best intepretation for all the currently observed properties of NuSTAR J095551+6940.8. This source offers an unprecedented opportunity to study the disk-magnetosphere interaction in a new regime of supercritical accretion, and across the transition between-radiation pressure and gas-pressure dominance inside the disk.

description: In this paper, we study the stochastic optimization of cloud radio access networks (C-RANs) by joint remote radio head (RRH) activation and beamforming in the downlink. Unlike most previous works that only consider a static optimization framework with full traffic buffers, we formulate a dynamic optimization problem by explicitly considering the effects of random traffic arrivals and time-varying channel fading. The stochastic formulation can quantify the tradeoff between power consumption and queuing delay. Leveraging on the Lyapunov optimization technique, the stochastic optimization problem can be transformed into a per-slot penalized weighted sum rate maximization problem, which is shown to be non-deterministic polynomial-time hard. Based on the equivalence between the penalized weighted sum rate maximization problem and the penalized weighted minimum mean square error (WMMSE) problem, the group sparse beamforming optimization based WMMSE algorithm and the relaxed integer programming based WMMSE algorithm are proposed to efficiently obtain the joint RRH activation and beamforming policy. Both algorithms can converge to a stationary solution with low-complexity and can be implemented in a parallel manner, thus they are highly scalable to large-scale C-RANs. In addition, these two proposed algorithms provide a flexible and efficient means to adjust the power-delay tradeoff on demand.

description: We study a binary system composed of point particles of unequal masses in eccentric orbits in the linear regime of the characteristic formulation of general relativity, generalising a previous study found in the literature in which a system of equal masses in circular orbits is considered. We also show that the boundary conditions on the time-like world tubes generated by the orbits of the particles can be extended beyond circular orbits. Concerning the power lost by the emission of gravitational waves, it is directly obtained from the Bondi's News function. It is worth stressing that our results are completely consistent, because we obtain the same result for the power derived by Peters and Mathews, in a different approach, in their seminal paper of 1963. In addition, the present study constitutes a powerful tool to construct extraction schemes in the characteristic formalism to obtain the gravitational radiation produced by binary systems during the inspiralling phase.

description: Objective: To estimate the population prevalence and treatable burden of severe aortic stenosis (AS) in the UK.MethodsWe adapted a contemporary model of the population profile of symptomatic and asymptomatic severe AS in Europe and North America to estimate the number of people aged ≥55 years in the UK who might benefit from surgical aortic valve replacement (SAVR) or transcatheter aortic valve implantation (TAVI).ResultsWith a point prevalence of 1.48%, we estimate that 291 448 men and women aged ≥55 years in the UK had severe AS in 2019. Of these, 68.3% (199 059, 95% CI 1 77 201 to 221 355 people) would have been symptomatic and, therefore, more readily treated according to their surgical risk profile; the remaining 31.7% of cases (92 389, 95% CI 70 093 to 144 247) being asymptomatic. Based on historical patterns of intervention, 58.4% (116 251, 95% CI 106 895 to 1 25 606) of the 199 059 symptomatic cases would qualify for SAVR, with 7208 (95% CI 7091 to 7234) being assessed as being in a high, preoperative surgical risk category. Among the remaining 41.6% (82 809, 95% CI 73 453 to 92 164) of cases potentially unsuitable for SAVR, an estimated 61.7% (51 093, 95% CI 34 780 to 67 655) might be suitable for TAVI. We estimate that 172 859 out of 291 448 prevalent cases of severe AS (59.3%) will subsequently die within 5 years without proactive management.ConclusionsThese data suggest a high burden of severe AS in the UK requiring surgical or transcatheter intervention that challenges the ongoing capacity of the National Health Service to meet the needs of those affected.

description: A theoretical investigation on slow light propagation based on eletromagnetically induced transparency in a three-level quantum-dot system is performed including non-Markovian effects and correlated dephasing reservoirs. It is demonstraonated that the non-Markovian nature of the process is quite essential even for conventional dephasing typical of quantum dots leading to significant enhancement or inhibition of the group velocity slow-down factor as well as to the shifting and distortion of the transmission window. Furthermore, the correlation between dephasing reservoirs may also either enhance or inhibit non-Markovian effects.
