description: In replica exchange Monte Carlo (REM), tuning of the temperature set and the exchange scheduling are crucial in improving the accuracy and reducing calculation time. In multi-dimensional simulated tempering, the first order phase transition is accessible. Therefore it is important to study the tuning of parameter set and the scheduling of exchanges in the parallel counterpart, the multi-dimensional REM. We extend Hukushima's constant exchange probability method to multi-dimensional REM for the parameter set. We further propose a combined method to use this set and the Bittner-Nussbaumer-Janke's PT tau algorithm for scheduling. We test the proposed method in two-dimensional spin-1 Blume-Capel model and find that it works efficiently, including the vicinity of the first order phase transition.

description: Through in situ photoemission spectroscopy (PES), we investigated the changes in the electronic structure of Cr-doped VO2 films coherently grown on TiO2 (001) substrates. The electronic phase diagram of CrxV1-xO2 is drawn by a combination of electric and spectroscopic measurements. The phase diagram is similar to that of bulk CrxV1-xO2, while the temperature of metal-insulator transition (TMIT) is significantly suppressed by the epitaxial strain effect. In the range of x = 0-0.04, where TMIT remains unchanged as a function of x, the PES spectra show dramatic change across TMIT, demonstrating the characteristic spectral changes associated with the Peierls phenomenon. In contrast, for x > 0.04, the TMIT linearly increases, and the metal-insulator transition (MIT) may disappear at x = 0.08-0.12. The PES spectra at x = 0.08 exhibit pseudogap behavior near the Fermi level, whereas the characteristic temperature-induced change remains almost intact, suggesting the existence of local V-V dimerization. The suppression of V-V dimerization with increasing x was confirmed by polarization-dependent x-ray absorption spectroscopy. These spectroscopic investigations reveal that the energy gap and V 3d states are essentially unchanged with 0 $\le$ x $\le$ 0.08 despite the suppression of V-V dimerization. The invariance of the energy gap with respect to x suggests that the MIT in CrxV1-xO2 arises primarily from the strong electron correlations, namely the Peierls-assisted Mott transition. Meanwhile, the pseudogap at x = 0.08 eventually evolves to a full gap (Mott gap) at x = 0.12, which is consistent with the disappearance of the temperature-dependent MIT in the electronic phase diagram. These results demonstrate that a Mott insulating phase without V-V dimerization is stabilized at x > 0.08 as a result of the superiority of Mott instability over the Peierls one.

description: The propagation of localized solitons in the presence of large-scale waves is a fundamental problem, both physically and mathematically, with applications in fluid dynamics, nonlinear optics and condensed matter physics. Here, the evolution of a soliton as it interacts with a rarefaction wave or a dispersive shock wave, examples of slowly varying and rapidly oscillating dispersive mean fields, for the Korteweg-de Vries equation is studied. Step boundary conditions give rise to either a rarefaction wave (step up) or a dispersive shock wave (step down). When a soliton interacts with one of these mean fields, it can either transmit through (tunnel) or become embedded (trapped) inside, depending on its initial amplitude and position. A comprehensive review of three separate analytical approaches is undertaken to describe these interactions. First, a basic soliton perturbation theory is introduced that is found to capture the solution dynamics for soliton-rarefaction wave interaction in the small dispersion limit. Next, multiphase Whitham modulation theory and its finite-gap description are used to describe soliton-rarefaction wave and soliton-dispersive shock wave interactions. Lastly, a spectral description and an exact solution of the initial value problem is obtained through the Inverse Scattering Transform. For transmitted solitons, far-field asymptotics reveal the soliton phase shift through either type of wave mentioned above. In the trapped case, there is no proper eigenvalue in the spectral description, implying that the evolution does not involve a proper soliton solution. These approaches are consistent, agree with direct numerical simulation, and accurately describe different aspects of solitary wave-mean field interaction

Year: 2010

description: It is widely accepted that health systems are not producing the desired output of health interventions due to factors such as insufficient skilled and experienced health personnel, health personnel that lack motivation, lack of management skills, poor working conditions and environment, and inadequate remuneration. This study explores the factors that positively as well as negatively affect performance of nurses who are working in hospitals and Health centers administrated by Addis Ababa Health Bureau with the endeavor of providing a recommendation for improving the performance of nurses. The study followed a quantitative research approach using an explorative descriptive design. A survey method using questionnaires was applied. The response to the study was positive as a response rate of 85% was obtained. Baseline results revealed various factors, which affect performance. The study revealed that hospitals and health centers administrated by Addis Ababa health Bureau have major deficiencies in human resource management aspects such as to remuneration, benefits, reward, recognition, knowledge and skills base, staff development, Management skills, and competencies. These aspects are strongly associated with level of performance of health personnel. Based on the results, recommendations were proposed: enhancing the nursing profession; strengthening knowledge and expertise, including management skills; improving performance; and generating knowledge through research

description: In this paper, we model the salient object detection problem under a probabilistic framework encoding the boundary connectivity saliency cue and smoothness constraints in an optimization problem. We show that this problem has a closed form global optimum which estimates the salient object. We further show that along with the probabilistic framework, the proposed method also enjoys a wide range of interpretations, i.e. graph cut, diffusion maps and one-class classification. With an analysis according to these interpretations, we also find that our proposed method provides approximations to the global optimum to another criterion that integrates local/global contrast and large area saliency cues. The proposed approach achieves mostly leading performance compared to the state-of-the-art algorithms over a large set of salient object detection datasets including around 17k images for several evaluation metrics. Furthermore, the computational complexity of the proposed method is favorable/comparable to many state-of-the-art techniques.

description: The merger of binary neutron-stars systems combines in a single process: extreme gravity, copious emission of gravitational waves, complex microphysics, and electromagnetic processes that can lead to astrophysical signatures observable at the largest redshifts. We review here the recent progress in understanding what could be considered Einstein's richest laboratory, highlighting in particular the numerous significant advances of the last decade. Although special attention is paid to the status of models, techniques, and results for fully general-relativistic dynamical simulations, a review is also offered on initial data and advanced simulations with approximate treatments of gravity. Finally, we review the considerable amount of work carried out on the post-merger phase, including: black-hole formation, torus accretion onto the merged compact object, connection with gamma-ray burst engines, ejected material, and its nucleosynthesis.

description: Recent advances in artificial intelligence (AI) have significantly intensified research in the geoscience and remote sensing (RS) field. AI algorithms, especially deep learning-based ones, have been developed and applied widely to RS data analysis. The successful application of AI covers almost all aspects of Earth observation (EO) missions, from low-level vision tasks like super-resolution, denoising and inpainting, to high-level vision tasks like scene classification, object detection and semantic segmentation. While AI techniques enable researchers to observe and understand the Earth more accurately, the vulnerability and uncertainty of AI models deserve further attention, considering that many geoscience and RS tasks are highly safety-critical. This paper reviews the current development of AI security in the geoscience and RS field, covering the following five important aspects: adversarial attack, backdoor attack, federated learning, uncertainty and explainability. Moreover, the potential opportunities and trends are discussed to provide insights for future research. To the best of the authors' knowledge, this paper is the first attempt to provide a systematic review of AI security-related research in the geoscience and RS community. Available code and datasets are also listed in the paper to move this vibrant field of research forward.

description: In this paper, we prove that every equivalence class in the quotient group of integral $1$-currents modulo $p$ in Euclidean space contains an integral current, with quantitative estimates on its mass and the mass of its boundary. Moreover, we show that the validity of this statement for $m$-dimensional integral currents modulo $p$ implies that the family of $(m-1)$-dimensional flat chains of the form $pT$, with $T$ a flat chain, is closed with respect to the flat norm. In particular, we deduce that such closedness property holds for $0$-dimensional flat chains, and, using a proposition from "The structure of minimizing hypersurfaces mod $4$" by Brian White, also for flat chains of codimension $1$.

title: Restorative justice & family abuse: extending a socio-legal approach to cases of forced marriage in Scotland
Creators: name: Gaw, Cameron J.
Publisher: name: University of Glasgow
Year: 2022

description: This thesis offers a comprehensive assessment of the theoretical and practical connections between restorative justice and forced marriage from a Scottish perspective. Existing legal models aimed at addressing Scotland’s forced marriage problem are focused on punitive sanctions and extracting victims from their abusive familial and community environments. It is argued that this top-down regulatory framework is falling short in several respects, leaving significant numbers of victims without legal protection. Recent evidence suggests some welfare organisations in Scotland are prepared to offer restorative and mediatory practices as alternative interventions despite significant opposition. In parallel, the Scottish Government’s recent commitment to a national model of restorative justice has yet to consider potential inclusion of forced marriage cases and implications for those involved. The aim of this thesis is twofold: to assess the potential benefits of restorative practice as an alternative legal approach to forced marriage; and consider how these cases might be incorporated within Scotland’s national restorative justice strategy. Chapter one outlines the broader context to these developments and draws key boundaries in conceptualising restorative justice. An assessment of Scots forced marriage law is offered in Chapter two, followed by an overview of existing and prospective restorative justice landscapes in Chapter three. Chapter four considers the positioning of forced marriage within the surrounding feminist literature on restorative justice, reframing the existing discourse. Chapter five analyses how a restorative approach might address some of the crucial conceptual concerns of forced marriage through dialogic engagement, taking note of important feminist insights for addressing power imbalances and instilling victim safety. Discussion concludes in Chapter six with key considerations for a more desirable professional response to forced marriage through restorative practice. The overall objective is to demonstrate how the positioning of these cases within a socio-legal framework of restorative justice might extend protection to a great number of victims and offer fuller appreciation of the cultural and collectivist contexts within which minority individuals exercise marital autonomy.

The study uses intraday data for the S&P 500 stocks from the New York Stock Exchange. After establishing an empirical overview we compare the quantile-based correlation function to stochastic processes from the GARCH family and find striking differences. This motivates us to propose the quantile-based correlation function as a powerful tool to assess the agreements between stochastic processes and empirical data.

Synthesis of High Refractive Index La3+ doped BaTiO3 Nanoparticles for Retroreflective Application Via Water Assisted Solid State Reaction

description: To guarantee the safe and well-organized movement of traffic on highway during bad weather and nighttime conditions, traffic signs, markings, helmet and safety textile paints have to be illuminated and made of retro-reflective materials. Materials having collective fluorescent and retro-reflective properties importantly improve visibility. For production of these materials Ceramics of glass having high refractive index are used. Most ceramic materials for different applications are synthesized by a conventional solid state reaction (SSR) method. In solid state reaction ionic diffusion in an ionic crystal is very sluggish at about room temperature Therefore it needs a high temperature conditions for boosting the reactivity between raw materials. Liquid phase reaction also can arise at relatively low temperature to SSR but needs additional temperature to dry the solvent and superior equipment for separation. Methods currently used to synthesis glass beads such as Container less flamespray, Conventional SSR, Molten salt etc. requires high temperature (780 ºC-1300ºC) to synthesize high purity glass beads. Furthermore, products obtained using these methods have large bead/ powder sizes. activated BaTiO3 at 100ºc. The starting materials, La2O3, TiO2, and Ba(OH)2.8H2O, weighed according to the stoichiometric ratio and mixed for 15 minutes with 8% of deionized water, Store in an automatic Oven for 6 hours at 100ºc. The La doping level were 0%, 5% and 10%. In this study, a WASSR route is employed to synthesize nano-sized La 3+ X-ray diffraction of the as prepared new material confirmed the product has a structure of Tetragonal BaTiO3 having a size ranging from 19.39 to 21.64nm.EDS mapping of the as prepared sample showed uniform distribution of components. From UV-Vi spectrometry, the La 3+ activated BaTiO3 nanoparticles has shown a refractive index of 3.392 when La doping was 1%. Raman spectroscopy also confirmed the structure of the as prepared sample is Tetragonal. The refractive index of nanoparticles greatly increased the wide wavelength range (426–900 nm), which is very useful for some special surfaces that require illumination from reflection of light rays, such as protective reflective helmet or clothes, road side signs, etc. In addition, it can be used as heat reflective layer, which solves the urban heat island effect.
Fate of the one-dimensional Ising quantum critical point coupled to a gapless boson

description: The problem of a quantum Ising degree of freedom coupled to a gapless bosonic mode appears naturally in many one dimensional systems, yet surprisingly little is known how such a coupling affects the Ising quantum critical point. We investigate the fate of the critical point in a regime, where the weak coupling renormalization group (RG) indicates a flow toward strong coupling. Using a renormalization group analysis and numerical density matrix renormalization group (DMRG) calculations we show that, depending on the ratio of velocities of the gapless bosonic mode and the Ising critical fluctuations, the transition may remain continuous or become fluctuation-driven first order. The two regimes are separated by a tri-critical point of a novel type.

description: Thermal photons from the QGP provide important information about the interaction among plasma constituents. The photon production rate from a thermally equilibrated system is proportional to the transverse spectral function $ρ_T(ω=|\vec k|, \vec k)$. One can also calculate the photon production rate from the difference between $ρ_T(ω,\vec k)$ (transverse) and $ρ_L(ω,\vec k)$ (longitudinal) projections, as $ρ_L$ vanishes on the photon point. Because the UV part of $ρ_T-ρ_L$ is suppressed, the corresponding Euclidean correlator receives most of its contribution from the IR part. We calculate the $T\!-\!L$ correlator on $N_f=2+1$ flavour HISQ configurations with $m_l=m_s/5$ at temperature of about $1.15\,T_{pc}$ (220 MeV). We have used two ansätze for the spectral function: 1) A polynomial connected to the UV region consistent with OPE expansion and 2) a hydro-inspired spectral function. We have also applied the Backus-Gilbert method to estimate the spectral function. All these different approaches are combined to estimate the photon production rate.

description: In this paper, we characterize major depression (MD) as a complex dynamical system in which symptoms (e.g., insomnia and fatigue) are directly connected to one another in a network structure. We hypothesize that individuals can be characterized by their own network with unique architecture and resulting dynamics. With respect to architecture, we show that individuals vulnerable to developing MD are those with strong connections between symptoms: e.g., only one night of poor sleep suffices to make a particular person feel tired. Such vulnerable networks, when pushed by forces external to the system such as stress, are more likely to end up in a depressed state; whereas networks with weaker connections tend to remain in or return to a healthy state. We show this with a simulation in which we model the probability of a symptom becoming active as a logistic function of the activity of its neighboring symptoms. Additionally, we show that this model potentially explains some well-known empirical phenomena such as spontaneous recovery as well as accommodates existing theories about the various subtypes of MD. To our knowledge, we offer the first intra-individual, symptom-based, process model with the potential to explain the pathogenesis and maintenance of major depression.

On the origin of the scatter broadening of fast radio burst pulses and astrophysical implications

description: Fast radio bursts (FRBs) have been identified as extragalactic sources which can make a probe of turbulence in the intergalactic medium (IGM) and their host galaxies. To account for the observed millisecond pulses caused by scatter broadening, we examine a variety of possible models of electron density fluctuations in both the IGM and the host galaxy medium. We find that a short-wave-dominated power-law spectrum of density, which may arise in highly supersonic turbulence with pronounced local dense structures of shock-compressed gas in the host interstellar medium (ISM), can produce the required density enhancements at sufficiently small scales to interpret the scattering timescale of FRBs. It implies that an FRB residing in a galaxy with efficient star formation in action tends to have a broadened pulse. The scaling of the scattering time with dispersion measure (DM) in the host galaxy varies in different turbulence and scattering regimes. The host galaxy can be the major origin of scatter broadening, but contribute to a small fraction of the total DM. We also find that the sheet-like structure of density in the host ISM associated with folded magnetic fields in a viscosity-dominated regime of magnetohydrodynamic (MHD) turbulence cannot give rise to strong scattering. Furthermore, valuable insights into the IGM turbulence concerning the detailed spatial structure of density and magnetic field can be gained from the observed scattering timescale of FRBs. Our results are in favor of the suppression of micro-plasma instabilities and the validity of collisional-MHD description of turbulence properties in the collisionless IGM.

description: This Letter proposes a new signature for confining dark sectors at the Large Hadron Collider. Under the assumption of a QCD-like hidden sector, hadronic jets containing stable dark bound states could manifest in proton-proton collisions. We present a simplified model with a $Z'$ boson yielding the production of jets made up of dark bound states and subsequently leading to the decays of those that are unstable to $τ$ leptons and Standard Model quarks. The resulting signature is characterised by non-isolated $τ$ lepton pairs inside semi-visible jets. We estimate the constraints on our model from existing CMS and ATLAS analyses. We propose a set of variables that leverage the leptonic content of the jet and exploit them in a supervised jet tagger to enhance the signal-to-background separation. Furthermore, we discuss the performance and limitations of current triggers for accessing sub-TeV $Z'$ masses, as well as possible strategies that can be adopted by experiments to access such low mass regions. We estimate that with the currently available triggers, a high mass search can claim a $5 σ$ discovery (exclusion) of the $Z'$ boson with a mass up to 4.5TeV (5.5TeV) with the full Run2 data of the LHC when the fraction of unstable dark hadrons decaying to $τ$ lepton pairs is around $50\%$, and with a coupling of the $Z'$ to right-handed up-type quarks of 0.25. Furthermore, we show that, with new trigger strategies for Run3, it may be possible to access $Z'$ masses down to 700 GeV, for which the event topology is still composed of two resolved semi-visible jets.

Gaussian Processes Online Observation Classification for RSSI-based Low-cost Indoor Positioning Systems

description: In this paper, we propose a real-time classification scheme to cope with noisy Radio Signal Strength Indicator (RSSI) measurements utilized in indoor positioning systems. RSSI values are often converted to distances for position estimation. However due to multipathing and shadowing effects, finding a unique sensor model using both parametric and non-parametric methods is highly challenging. We learn decision regions using the Gaussian Processes classification to accept measurements that are consistent with the operating sensor model. The proposed approach can perform online, does not rely on a particular sensor model or parameters, and is robust to sensor failures. The experimental results achieved using hardware show that available positioning algorithms can benefit from incorporating the classifier into their measurement model as a meta-sensor modeling technique.

description: Habitat destruction and overexploitation are the main threats to biodiversity and where they co-occur, their combined impact is often larger than their individual one. Yet, detailed knowledge of the spatial footprints of these threats is lacking, including where they overlap and how they change over time. These knowledge gaps are real barriers for effective conservation planning. Here, we develop a novel approach to reconstruct the individual and combined footprints of both threats over time. We combine satellite-based land-cover change maps, habitat suitability models and hunting pressure models to demonstrate our approach for the community of larger mammals (48 species >1 kg) across the 1.1 million km2 Gran Chaco region, a global deforestation hotspot cov-ering parts of Argentina, Bolivia and Paraguay. This provides three key insights. First, we find that the footprints of habitat destruction and hunting pressure expanded con-siderably between 1985 and 2015, across ~40% of the entire Chaco – twice the area affected by deforestation. Second, both threats increasingly acted together within the ranges of larger mammals in the Chaco (17% increase on average, ± 20% SD, cumula-tive increase of co-occurring threats across 465 000 km2), suggesting large synergistic effects. Conversely, core areas of high-quality habitats declined on average by 38%. Third, we identified remaining priority areas for conservation in the northern and central Chaco, many of which are outside the protected area network. We also identify hotspots of high threat impacts in central Paraguay and northern Argentina, providing a spatial template for threat-specific conservation action. Overall, our findings suggest increasing synergistic effects between habitat destruction and hunting pressure in the Chaco, a situation likely common in many tropical deforestation frontiers. Our work highlights how threats can be traced in space and time to understand their individual and combined impact, even in situations where data are sparse.

description: Emerging technologies in the embedded domain enable the development of innovative software-driven solutions. Autonomous systems are a clear example of this trend and have attracted considerable attention from different industrial sectors and research fields. In fact, they can be considered game-changers for several domains, even for the functional safety domain. These innovative safety-related systems are characterized by an increasing software complexity and high-performance requirements. Hence, a desirable requirement is to deploy an Operating System (OS), such as Linux, on these next-generation complex safety-related systems to fully take advantage of its benefits (e.g., security, reliability, software updates, performance). However, implementing a software layer, such as the Linux kernel, on a resource-sharing architecture hinders the verification process so that it is no longer feasible to base it on traditional approaches, most notably on testing. The potential of traditional testing lies in achieving exhaustive coverage, which is extremely difficult (if even feasible) in the systems with the complexity of those being developed today. Therefore, we believe that testing of software elements needs to be combined with analysis to pave the way towards safety assurance. This thesis contributes with a novel statistical analysis technique to quantify the execution path coverage of the Linux kernel and for estimating the risk entailed by untested execution paths. In the first part, the main gaps in the field of test coverage are examined, specially focused on the Linux kernel. Afterward, different research activities are conducted to statistically estimate the test coverage by the analysis of the execution paths traversed during the testing campaign. The inherent non-determinism of the Linux kernel and the viability of estimating the coverage with different methods is further demonstrated. An additional statistical method to calculate the execution probability of untested paths and determine the risk they entail is proposed. Finally, a technique that combines all these contributions in order to quantify the testing process and the risk associated with the uncovered paths. With the above contributions, this thesis proposes moving towards a statistical approach to quantify the coverage and the risk, and bridge the gap towards the certification of safety-related complex applications based on Linux or other complex OS that run on Commercial Off-The-Shelf (COTS) multi-core devices.

description: We report a measurement of the power spectrum of cosmic microwave background (CMB) lensing from two seasons of Atacama Cosmology Telescope Polarimeter (ACTPol) CMB data. The CMB lensing power spectrum is extracted from both temperature and polarization data using quadratic estimators. We obtain results that are consistent with the expectation from the best-fit Planck LCDM model over a range of multipoles L=80-2100, with an amplitude of lensing A_lens = 1.06 +/- 0.15 (stat.) +/- 0.06 (sys.) relative to Planck. Our measurement of the CMB lensing power spectrum gives sigma_8 Omega_m^0.25 = 0.643 +/- 0.054; including baryon acoustic oscillation scale data, we constrain the amplitude of density fluctuations to be sigma_8 = 0.831 +/- 0.053. We also update constraints on the neutrino mass sum. We verify our lensing measurement with a number of null tests and systematic checks, finding no evidence of significant systematic errors. This measurement relies on a small fraction of the ACTPol data already taken; more precise lensing results can therefore be expected from the full ACTPol dataset.

description: Glucose is a primary source of energy for the body’s cells. It is a simple sugar (monosaccharide) that is absorbed into the bloodstream after the digestion of carbohydrates from foods.

Here’s how glucose functions as an energy source:

Absorption and Transport: After consuming carbohydrates, they are broken down into glucose in the digestive system. Glucose enters the bloodstream, where it is transported to cells throughout the body.

Cellular Uptake: Cells take up glucose from the bloodstream via insulin, a hormone produced by the pancreas. Insulin facilitates the entry of glucose into cells, especially muscle and fat cells.

Glycolysis: Inside the cell, glucose undergoes glycolysis, a process that breaks it down into pyruvate while producing a small amount of ATP (adenosine triphosphate), the energy currency of the cell.

description: We present charmonium and bottomonium correlators and corresponding reconstructed spectral functions from full QCD calculations in the pseudoscalar channel. Correlators are obtained using a mixed-action approach, clover-improved Wilson valence quarks on gauge field configurations generated with $N_f=2+1$ HISQ sea quarks, with physical strange quark masses and light quark masses corresponding to $m_π=315$ MeV. The charm and bottom quark masses are tuned to reproduce the experimental mass spectrum of the spin averaged quarkonium vector mesons from the particle data group. For the spectral reconstruction, we use models based on perturbative spectral functions from different frequency regions like resummed thermal contributions around the threshold from pNRQCD and vacuum contributions well above the threshold. We show preliminary results of the reconstructed spectral function obtained for the first time in our study for full QCD.

description: The auditory system displays remarkable sensitivity and frequency discrimination, attributes shown to rely on an amplification process that involves a mechanical as well as a biochemical response. Models that display proximity to an oscillatory onset (a.k.a. Hopf bifurcation) exhibit a resonant response to distinct frequencies of incoming sound, and can explain many features of the amplification phenomenology. To understand the dynamics of this resonance, frequency locking is examined in a system near the Hopf bifurcation and subject to two types of driving forces: additive and parametric. Derivation of a universal amplitude equation that contains both forcing terms enables a study of their relative impact on the hair cell response. In the parametric case, although the resonant solutions are 1:1 frequency locked, they show the coexistence of solutions obeying a phase shift of $π$, a feature typical of the 2:1 resonance. Different characteristics are predicted for the transition from unlocked to locked solutions, leading to smooth or abrupt dynamics in response to different types of forcing. The theoretical framework provides a more realistic model of the auditory system, which incorporates a direct modulation of the internal control parameter by an applied drive. The results presented here can be generalized to many other media, including Faraday waves, chemical reactions, and nonlinear optics, which are known to exhibit resonant behavior.
