description: Next-generation cosmological surveys will observe larger cosmic volumes than ever before, enabling us to access information on the primordial Universe, as well as on relativistic effects. In a companion paper, we applied a Fisher analysis to forecast the expected precision on $f_{\rm NL}$ and the detectability of the lensing magnification and Doppler contributions to the power spectrum. Here we assess the bias on the best-fit values of $f_{\rm NL}$ and other parameters, from neglecting these light-cone effects. We consider forthcoming 21cm intensity mapping surveys (SKAO) and optical galaxy surveys (DESI and Euclid), both individually and combined together. We conclude that lensing magnification at higher redshifts must be included in the modelling of spectroscopic surveys. If lensing is neglected in the analysis, this produces a bias of more than 1$σ$ - not only on $f_{\rm NL}$, but also on the standard cosmological parameters.

description: In this paper we analyze the propagation of a charged scalar field in a Reissner-Nordström black hole endowed with one anisotropic fluid that can play the role of a cosmological term for certain set of parameters. The evolution of a scalar wave scattering is examined giving rise to the same superradiant scattering condition as in the de Sitter case. In addition, an analysis of the modes coming from the application of quasinormal boundary conditions is presented. Some special cases displaying analytical solutions for the quasinormal frequencies are discussed. Moreover, the superradiant condition is adapted to the quasinormal problem triggering unstable modes, what is confirmed by our numerical analysis.

description: We obtain a limit of a hierarchical Bayes estimator of a finite population mean when the sample size is large. The limit is in the sense of ordinary calculus, where the sample observations are treated as fixed quantities. Our result suggests a simple way to correct the hierarchical Bayes estimator to achieve design-consistency, a well-known property in the traditional randomization approach to finite population sampling. We also suggest three different measures of uncertainty of our proposed estimator.

Systemically and emotionally-focused marital therapies : a comparative outcome study
Creators: name: Goldman, Audrey A.
Publisher: name: University of British Columbia
Year: 2010

description: The present study compares the effectiveness of two interventions in the treatment of marital discord: a sequentially integrated systemic intervention focusing on reframing interactional patterns and an emotionally focused intervention, focusing on accessing emotional experiences underlying interaction patterns. Forty-two couples seeking therapy were randomly assigned to one of these treatments or to a wait-list control group. Each treatment was administered in ten weekly sessions by seven experienced therapists. Through an implementation check it was determined that the treatments had been implemented in accordance with the treatment manuals. Tests of equivalence showed that the groups were equivalent on pre-test levels, demographic variables and in the strength of their working alliance with their therapists. Post-test results indicated that both treatment groups made significant gains compared to untreated controls on measures of marital adjustment, conflict resolution, target complaint reduction and goal attainment, but that neither treatment group gained significantly more than the other. At follow-up, a further 16 weeks later, post-test levels on all measures were maintained by the sequentially integrated systemic group. The emotionally-focused group maintained levels on conflict resolution, and continued to achieve target complaint improvement but slipped back on pre-test goals and relapsed on marital adjustment. Results suggest that two very different treatments, one of which had not been tested before, are both effective in helping couples alleviate marital distress, but that the sequentially integrated systemic therapy is more self-sustaining.

description: Automatic and accurate detection of anatomical landmarks is an essential operation in medical image analysis with a multitude of applications. Recent deep learning methods have improved results by directly encoding the appearance of the captured anatomy with the likelihood maps (i.e., heatmaps). However, most current solutions overlook another essence of heatmap regression, the objective metric for regressing target heatmaps and rely on hand-crafted heuristics to set the target precision, thus being usually cumbersome and task-specific. In this paper, we propose a novel learning-to-learn framework for landmark detection to optimize the neural network and the target precision simultaneously. The pivot of this work is to leverage the reinforcement learning (RL) framework to search objective metrics for regressing multiple heatmaps dynamically during the training process, thus avoiding setting problem-specific target precision. We also introduce an early-stop strategy for active termination of the RL agent's interaction that adapts the optimal precision for separate targets considering exploration-exploitation tradeoffs. This approach shows better stability in training and improved localization accuracy in inference. Extensive experimental results on two different applications of landmark localization: 1) our in-house prenatal ultrasound (US) dataset and 2) the publicly available dataset of cephalometric X-Ray landmark detection, demonstrate the effectiveness of our proposed method. Our proposed framework is general and shows the potential to improve the efficiency of anatomical landmark detection.

description: Studies of cluster mass and velocity anisotropy profiles are useful tests of dark matter models, and of the assembly history of clusters of galaxies. These studies might be affected by unknown systematics caused by projection effects. We aim at testing observational methods for the determination of mass and velocity anisotropy profiles of clusters of galaxies. Particularly, we focus on the MAMPOSSt technique (Mamon et al. 2013). We use results from two semi-analytic models of galaxy formation coupled with high-resolution N-body cosmological simulations, the catalog of De Lucia & Blaizot (2007) and the FIRE catalog based on the new GAlaxy Evolution and Assembly model. We test the reliability of the Jeans equation in recovering the true mass profile when full projected phase-space information is available. We examine the reliability of the MAMPOSSt method in estimating the true mass and velocity anisotropy profiles of the simulated halos when only projected phase-space information is available, as in observations. The spherical Jeans equation provides a reliable tool for the determination of cluster mass profiles, also for subsamples of tracers separated by galaxy color. Results are equally good for prolate and oblate clusters. Using only projected phase-space information, MAMPOSSt provides estimates of the mass profile with a standard deviation of 35-69 %, and a negative bias of 7-17 %, nearly independent of radius, and that we attribute to the presence of interlopers in the projected samples. The bias changes sign, that is, the mass is over-estimated, for prolate clusters with their major axis aligned along the line-of-sight. MAMPOSSt measures the velocity anisotropy profiles accurately in the inner cluster regions, with a slight overestimate in the outer regions, both for the whole sample of observationally-identified cluster members and separately for red and blue galaxies.

description: Phase separation and transitions among different molecular states are ubiquitous in living cells. Such transitions can be governed by local equilibrium thermodynamics or by active processes controlled by biological fuel. It remains largely unexplored how the behavior of phase-separating systems with molecular transitions differs between thermodynamic equilibrium and cases where detailed balance of the molecular transition rates is broken due to the presence of fuel. Here, we present a model of a phase-separating ternary mixture where two components can convert into each other. At thermodynamic equilibrium, we find that molecular transitions can give rise to a lower dissolution temperature and thus reentrant phase behavior. Moreover, we find a discontinuous thermodynamic phase transition in the composition of the droplet phase if both converting molecules attract themselves with similar interaction strength. Breaking detailed-balance of the molecular transition leads to quasi-discontinuous changes in droplet composition by varying the fuel amount for a larger range of inter-molecular interactions. Our findings showcase that phase separation with molecular transitions provides a versatile mechanism to control properties of intra-cellular and synthetic condensates via discontinuous switches in droplet composition.

description: The Brexit saga has reached a watershed moment. The United Kingdom withdrew from the European Union on 31 January 2020 and, following the expiry of the transitional period laid down in the EU-UK Withdrawal Agreement (EU-UK WA), it ceased to be bound by EU law. By the same token, it entered unchartered waters as a former EU Member State trying to find its place in an economically integrated world. This Article takes stock of the legal affairs as they stood on 1 January 2021. Yet, at the same time, it puts the new EU-UK legal framework in a broader perspective. For this purpose, it treats as a point of reference the Political Declaration, which was signed alongside the EU-UK Withdrawal Agreement. A good chunk of its potential has materialised in the EU-UK Trade and Cooperation Agreement (EU-UK TCA), although in some respects the proposals laid down in the Political Declaration are yet to turn into reality. Thus, to confine it to history books would be rather premature. While it is impossible to predict the future, the time is right to put the EU-UK legal framework under the microscope and to analyse its main legal parameters. The present Article offers such an insight. In part I, the centre of gravity is on institutional matters.

description: The exchange bias (EB) effect was discovered 60 years ago by Meiklejohn and Bean. Meanwhile the EB effect has become an integral part of modern magnetism with implications for basic research and for numerous device applications. The EB effect was the first of its kind which relates to an interface effect between two different classes of materials, here between a ferromagnet and an antiferromagnet. Here we review fundamental aspects of the exchange bias effect.

description: In this study, we tested the robustness of three communication networks extracted from the online forums included in the intranet platforms of three large companies. For each company we analyzed the communication among employees both in terms of network structure and content (language used). Over a period of eight months, we analyzed more than 52,000 messages posted by approximately 12,000 employees. Specifically, we tested the network robustness and the stability of a set of structural and semantic metrics, while applying several different node removal strategies. We removed the forum moderators, the spammers, the overly connected nodes and the nodes lying at the network periphery, also testing different combinations of these selections. Results indicate that removing spammers and very peripheral nodes can be a relatively low impact strategy in this context; accordingly, it could be used to clean the noise generated by these types of social actor and to reduce the computation complexity of the analysis. On the other hand, the removal of moderators seems to have a significant impact on the network connectivity and the shared content. The most affected variables are closeness centrality and contribution index. We also found that the removal of overly connected nodes can significantly change the network structure. Lastly, we compared the behavior of moderators with the other users, finding distinctive characteristics by which moderators can be identified when their list is unknown. Our findings can help online community managers to understand the role of moderators within intranet forums and can be useful for social network analysts who are interested in evaluating the effects of graph simplification techniques.
NET4Age-Friendly - Integrated health and wellbeing pathways

Publisher: name: Zenodo
Year: 2024

description: The purpose of this report is to provide an overview of the current state-of-the-art on integrated health and well-being pathways related to Smart Healthy Age-Friendly Environments (SHAFE).

The report further focuses on integrated care models in the world and delivers some inspiring examples. A critical benchmark was performed across EU member states to distil common practices, highlight disparities, and identify opportunities for improvement by aligning with EU policies and standards. The report continues with an analysis of the implementation of integrated care and well-being to explore the success factors and barriers. Special attention is paid to the use of ICT for social interaction of older adults to age in place. Policy recommendations are described to address the challenges of an ageing society. The conclusion of the report focuses on the recommendations for the Module of the Reference Framework of NET4Age on integrated health and well-being pathways

Integrated care for older people is most widespread. The relevant shift is proposed towards the integration of health and social care in order to improve functional potentials and slow down the decline in mental capacities in older people with joint and synchronised actions, thus improving both patient-centric and system-centric outcomes. Despite many examples of efforts, the evidence of successful strategies is limited. The lives of human beings are a continuum of genetic, biological, social, cultural and economic processes. Each stage in life influences the next and determines the health effects or risks. A life course perspective of an integrated conceptual approach is needed to enable long-term health gain. Therefore, the report also focuses on integrated care for younger people. Integrated mental healthcare for children and younger people is most found in the literature.

description: We show that the proportionately spaced emission bands in the dynamic spectrum of the Crab pulsar (Hankins T. H. & Eilek J. A., 2007, ApJ, 670, 693) fit the oscillations of the square of a Bessel function whose argument exceeds its order. This function has already been encountered in the analysis of the emission from a polarization current with a superluminal distribution pattern: a current whose distribution pattern rotates (with an angular frequency $ω$) and oscillates (with a frequency $Ω>ω$ differing from an integral multiple of $ω$) at the same time (Ardavan H., Ardavan A. & Singleton J., 2003, J Opt Soc Am A, 20, 2137). Using the results of our earlier analysis, we find that the dependence on frequency of the spacing and width of the observed emission bands can be quantitatively accounted for by an appropriate choice of the value of the single free parameter $Ω/ω$. In addition, the value of this parameter, thus implied by Hankins & Eilek's data, places the last peak in the amplitude of the oscillating Bessel function in question at a frequency ($\simΩ^3/ω^2$) that agrees with the position of the observed ultraviolet peak in the spectrum of the Crab pulsar. We also show how the suppression of the emission bands by the interference of the contributions from differring polarizations can account for the differences in the time and frequency signatures of the interpulse and the main pulse in the Crab pulsar. Finally, we put the emission bands in the context of the observed continuum spectrum of the Crab pulsar by fitting this broadband spectrum (over 16 orders of magnitude of frequency) with that generated by an electric current with a superluminally rotating distribution pattern.

description: We recover PH3 in the atmosphere of Venus in data taken with ALMA, using three different calibration methods. The whole-planet signal is recovered with 5.4σ confidence using Venus bandpass self-calibration, and two simpler approaches are shown to yield example 4.5-4.8σ detections of the equatorial belt. Non-recovery by Villanueva et al. is attributable to (a) including areas of the planet with high spectral-artefacts and (b) retaining all antenna baselines which raises the noise by a factor ~2.5. We release a data-processing script that enables our whole-planet result to be reproduced. The JCMT detection of PH3 remains robust, with the alternative SO2 attribution proposed by Villanueva et al. appearing inconsistent both in line-velocity and with millimetre-wavelength SO2 monitoring. SO2 contamination of the ALMA PH3-line is minimal. Net abundances for PH3, in the gas column above ~55 km, are up to ~20 ppb planet-wide with JCMT, and ~7 ppb with ALMA (but with signal-loss possible on scales approaching planetary size). Derived abundances will differ if PH3 occupies restricted altitudes - molecules in the clouds will contribute significantly less absorption at line-centre than equivalent numbers of mesospheric molecules - but in the latter zone, PH3 lifetime is expected to be short. Given we recover phosphine, we suggest possible solutions (requiring substantial further testing): a small collisional broadening coefficient could give narrow lines from lower altitude, or a high eddy diffusion coefficient could allow molecules to survive longer at higher altitudes. Alternatively, PH3 could be actively produced by an unknown mechanism in the mesosphere, but this would need to be in addition to cloud-level PH3 detected retrospectively by Pioneer-Venus.

description: A $\bar{K}\bar{K}N$ system with $I=1/2$ and $J^P=1/2^+$ is investigated with non-relativistic three-body calculations by using effective $\bar{K}N$ and $\bar K \bar K$ interactions. The present investigation suggests that a weakly bound state for the $\bar{K}\bar{K}N$ system can be formed below the two-body threshold of $\bar{K}$ and quasibound $\bar{K}N$ with a $40 \sim 60$ MeV decay width of $\bar{K}\bar{K}N\to πY\bar{K}$. This corresponds to an excited $Ξ$ baryon with $J^P=1/2^+$ located around 1.9 GeV. Studying the wave function of the $\bar{K}\bar{K}N$ system obtained in this formulation, we find that the three-body bound system has a characteristic structure of $\bar K N$+$\bar K$ cluster with spatial extent.

Un paradigma innovativo per moderni servizi di rete, il Service Switching
Creators: name: Manetti, Vittorio
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: The Internet was founded on a simple model in which the routers inside the network are responsible for forwarding packets from source to destination, and application programs run on the hosts connected to the edges of the network. However, the last few years have seen a blurring of the distinction between packet forwarding and application processing.
In such a context we propose a new paradigm for modern networked services: the Service Switching.
Composed by nodes capable to host services in addition to the traditional forwarding IP-based mechanism, the Service Switching infrastructure presents as its major feature the ability to implement a service migration mechanism among geographically distributed nodes, in order to make services seamlessly and transparently available to end-users regardless of their current location.
A Service Switch can store and host different services and applications with their respective data providing a secure and differentiated execution environment, and it can coordinate its behavior with other Service Switches in order to develop and provide services in a distributed way, according to optimal resource utilization schemes.
We propose an implementation of the Service Switching infrastructure based on virtualization mechanisms; such a technology allows to create isolated and self-contained virtual computing environments, completely independent from the underlying hardware.
Anisotropic tunneling magnetoresistance and tunneling anisotropic magnetoresistance: spin-orbit coupling in magnetic tunnel junctions

description: The effects of the spin-orbit interaction on the tunneling magnetoresistance of ferromagnet/semiconductor/normal metal tunnel junctions are investigated. Analytical expressions for the tunneling anisotropic magnetoresistance (TAMR) are derived within an approximation in which the dependence of the magnetoresistance on the magnetization orientation in the ferromagnet originates from the interference between Bychkov-Rashba and Dresselhaus spin-orbit couplings that appear at junction interfaces and in the tunneling region. We also investigate the transport properties of ferromagnet/semiconductor/ferromagnet tunnel junctions and show that in such structures the spin-orbit interaction leads not only to the TAMR effect but also to the anisotropy of the conventional tunneling magnetoresistance (TMR). The resulting anisotropic tunneling magnetoresistance (ATMR) depends on the absolute magnetization directions in the ferromagnets. Within the proposed model, depending on the magnetization directions in the ferromagnets, the interplay of Bychkov-Rashba and Dresselhaus spin-orbit couplings produces differences between the rates of transmitted and reflected spins at the ferromagnet/seminconductor interfaces, which results in an anisotropic local density of states at the Fermi surface and in the TAMR and ATMR effects. Model calculations for Fe/GaAs/Fe tunnel junctions are presented. Furthermore, based on rather general symmetry considerations, we deduce the form of the magnetoresistance dependence on the absolute orientations of the magnetizations in the ferromagnets.

description: This paper introduces a new approach to the study of rates of convergence for posterior distributions. It is a natural extension of a recent approach to the study of Bayesian consistency. In particular, we improve on current rates of convergence for models including the mixture of Dirichlet process model and the random Bernstein polynomial model.

description: Measurements of differential and double-differential cross sections of top quark pair ($\text{t}\overline{\text{t}}$) production are presented in the lepton+jets channels with a single electron or muon and jets in the final state. The analysis combines for the first time signatures of top quarks with low transverse momentum $p_\text{T}$, where the top quark decay products can be identified as separated jets and isolated leptons, and with high $p_\text{T}$, where the decay products are collimated and overlap. The measurements are based on proton-proton collision data at $\sqrt{s} = $ 13 TeV collected by the CMS experiment at the LHC, corresponding to an integrated luminosity of 137 fb$^{-1}$. The cross sections are presented at the parton and particle levels, where the latter minimizes extrapolations based on theoretical assumptions. Most of the measured differential cross sections are well described by standard model predictions with the exception of some double-differential distributions. The inclusive $\text{t}\overline{\text{t}}$ production cross section is measured to be $σ_{\text{t}\overline{\text{t}}} = $ 791 $\pm$ 25 pb, which constitutes the most precise measurement in the lepton+jets channel to date.

Attrition and completion in distance education : the student's perspective
Creators: name: Brindley, Jane E.
Publisher: name: University of British Columbia

description: This was an exploratory study which used Flanagan's (1954) Critical Incident Technique to examine students' experiences in taking their first distance education course. Specifically, the study asked what incidents hindered or facilitated persistence, and if reports of experiences from completers were different from those of non-completers. The 40 subjects for the sample were drawn at random from selected courses at Athabasca University, an open admission distance education institution serving students across Canada. All students were able to identify incidents which hindered or facilitated their progress. A mean of 6.6 incidents was reported per student. From the 265 incidents reported, 13 Basic Categories were formed, with a reliability of 94%. Only one category had less than 20% of students reporting in it. The highest proportion of students reporting in one category was 80%. Significant factors affecting attrition in distance education emerged from the study, as did findings about the similarities and differences between the experiences of completers and non-completers. Suggestions for how the findings might contribute to the development of a model of attrition and retention strategies are included in the discussion.

description: The computer vision community has paid much attention to the development of visible image super-resolution (SR) using deep neural networks (DNNs) and has achieved impressive results. The advancement of non-visible light sensors, such as acoustic imaging sensors, has attracted much attention, as they allow people to visualize the intensity of sound waves beyond the visible spectrum. However, because of the limitations imposed on acquiring acoustic data, new methods for improving the resolution of the acoustic images are necessary. At this time, there is no acoustic imaging dataset designed for the SR problem. This work proposed a novel backprojection model architecture for the acoustic image super-resolution problem, together with Acoustic Map Imaging VUB-ULB Dataset (AMIVU). The dataset provides large simulated and real captured images at different resolutions. The proposed XCycles BackProjection model (XCBP), in contrast to the feedforward model approach, fully uses the iterative correction procedure in each cycle to reconstruct the residual error correction for the encoded features in both low- and high-resolution space. The proposed approach was evaluated on the dataset and showed high outperformance compared to the classical interpolation operators and to the recent feedforward state-of-the-art models. It also contributed to a drastically reduced sub-sampling error produced during the data acquisition.
The unified geometric theory of mesoscopic stochastic pumps and reversible ratchets

description: We construct a unifying theory of geometric effects in mesoscopic stochastic kinetics. We demonstrate that the adiabatic pump and the reversible ratchet effects, as well as similar new phenomena in other domains, such as in epidemiology, all follow from geometric phase contributions to the effective action in the stochastic path integral representation of the moment generating function. The theory provides the universal technique for identification, prediction and calculation of pump-like phenomena in an arbitrary mesoscopic stochastic framework.

title: A woman's world: a bioarchaeological approach to the Romano-British female life course
Creators: name: McGovern, Candace
Publisher: name: University of Reading
Year: 2019

description: This thesis examines Romano-British women using a life course approach and from a holistic perspective by combining archaeological, historical and biological information. Within the female life course three physical events or transitions occur which directly relate to shifts within society: puberty, childbirth and menopause. These transitions were explored using 436 females between the ages of 10.0 and 44.9 from 11 southern Romano-British urban centres. These sites are of different legal status and size, with some examples bordering between urban and rural, providing insights into the lower status and local populations as well as towns of higher legal status. All individuals are dated to the later (2nd – 5 th century) Roman period. The Females between 10.0 and 24.9 years of age were included within the puberty subsample (n=136) and placed into six categories ranging from Initiation to Completion. Puberty primarily took place over 5 years with a mean age for menarche of 14.1 years. The shape and development of the pelvis also directly impacts a successful pregnancy and vaginal birth. Based on measurements of the pelvic inlet, midplane and outlet, 398 females were assigned to three categories: no contraction, at-risk and high risk. Within the sample, 100% (n=12) of females aged 13.0-15.9 years and 78.6% (n=11) of those between 16.0 and 17.9 years were contracted. Therefore, is highly unlikely that women under 18 years were frequently able to deliver vaginally. The developmental obstetric dilemma (DOD) hypothesis was investigated through pelvis typology and pelvimetry. Pathologies and morphological changes associated with obstetrics including prematurely fused coccyx and osteophyte growth were also examined as potential hazards. Stature, body mass (BM) and Body Mass Index (BMI) were determined based on femoral measurements. This research is the first to explore the female life course using a bioarchaeological approach to puberty and childbirth.

description: We report time-resolved optical CCD photometry on newly discovered SU UMa-type dwarf novae, FL TrA and CTCV J0549-4921. During the 2006 August outburst, we detected superhumps with a period of 0.59897(11) days for FL TrA, clarifying the SU UMa nature of the system. On the first night of our observations on FL TrA, the object showed no superhumps. This implies that it takes a few days for full development of superhumps. The superhump period variation diagram of FL TrA was similar to that observed in some WZ Sge stars and short period SU UMa-type stars. This indicates that the system is closely related to WZ Sge stars and SU UMa stars having short orbital periods. For CTCV J0549-4921, the candidates of the mean superhump period are 0.083249(10) days and 0.084257(8) days, respectively. Due to a lack of the observations, we cannot determine the true superhump period, but the latter period is favorable. Using the ASAS-3 archive, it turned out that the system shows only four outbursts over the past 6 years. The outburst amplitude of CTCV J0549-4921 was relatively small, with about 4.5 mag. One possibility is that mass evaporation may play a role during quiescence.

Magnetic turnstiles in nonresonant stellarator divertor

description: Non-resonant stellarator divertors have magnetic flux tubes, called magnetic turnstiles, that cross cantori, which are fractal remnants of destroyed invariant tori with holes, that lie outside the outermost confining surface. The exiting and entering flux tubes can be adjacent as is generally expected but can also have the unexpected feature of entering or exiting at separate locations of the cantori. Not only can there be two types of turnstiles, but pseudo turnstiles can also exist. A pseudo turnstile is formed when a cantorus has a sufficiently large, although limited, radial excursion to strike a surrounding chamber wall. The existence of non-adjacent and adjacent turnstiles and pseudo turnstiles resolves issues that arose in earlier simulations of nonresonant stellarator divertors [A. Punjabi and A. H. Boozer, Phys. Plasmas 27, 012503 (2020)].
