description: To improve the robustness of subband adaptive filter (SAF) against impulsive interferences, we propose two modified SAF algorithms with an individual scale function for each subband, which are derived by maximizing correntropy-based cost function and minimizing logarithm-based cost function, respectively, called MCC-SAF and LC-SAF. Whenever the impulsive interference happens, the subband scale functions can sharply drop the step size, which eliminate the influence of outliers on the tap-weight vector update. Therefore, the proposed algorithms are robust against impulsive interferences, and exhibit the faster convergence rate and better tracking capability than the sign SAF (SSAF) algorithm. Besides, in impulse-free interference environments, the proposed algorithms achieve similar convergence performance as the normalized SAF (NSAF) algorithm. Simulation results have demonstrated the performance of our proposed algorithms.

description: Deep neural networks significantly power the success of machine learning and artificial intelligence. Over the past decade, the community keeps designing architectures of deep layers and complicated connections. Many works in deep learning theory tried to understand deep networks from different perspectives and contributed to concrete analysis. However, the gap between deep learning theory and application is growingly large. Specifically, due to our partial understanding of our deep networks, current deep learning theory is not enough to guide us in designing practical neural architectures. This is mainly because of two gaps: 1) designing network architectures is very expensive, and 2) practical network architectures are much more complicated than what we studied in theory. Therefore, our core question to focus on is: how do we bridge these gaps, between deep learning theory and practical neural architecture designs? This dissertation will center around this challenge and tries to bridge the gap between the two worlds. First, current deep learning theory can inspire our architecture design (Chapter 3 and 4). We propose three theory-inspired indicators with strong correlations with networks' performance and they can be measured at networks' initialization without introducing any gradient descent cost. Based on these important metrics, we propose a training-free neural architecture design algorithm with extremely low computation and time costs. Second, the architecture design can further inspire deep learning theory (Chapter 5 and 6). By introducing two principled directions of the network's graph topology, we jointly analyze the impact of the network architecture on its convergence, expressivity, and generalization of networks, and demonstrate a "no free lunch" behavior in ReLU networks. Finally, a practical use case in the industry will be discussed (Chapter 7), where we design and scale up vision foundation models, again, without any training cost.

description: The system of a cold atomic gas in an optical lattice is governed by two factors: nonlinearity originating from the interparticle interaction, and the periodicity of the system set by the lattice. The high level of controllability associated with such an arrangement allows for the study of the competition and interplay between these two, and gives rise to a whole range of interesting and rich nonlinear effects. This review covers the basic idea and overview of such nonlinear phenomena, especially those corresponding to extended states. This includes "swallowtail" loop structures of the energy band, Bloch states with multiple periodicity, and those in "nonlinear lattices", i.e., systems with the nonlinear interaction term itself being a periodic function in space.

description: Fermions become polarized in a vorticular fluid due to spin-vorticity coupling. Such a polarization can be calculated from the Wigner function in a quantum kinetic approach. Extending previous results for chiral fermions, we derive the Wigner function for massive fermions up to the next-to-leading order in spatial gradient expansion. The polarization density of fermions can be calculated from the axial vector component of the Wigner function and is found to be proportional to the local vorticity $ω$. The polarizations per particle for fermions and anti-fermions decrease with the chemical potential and increase with energy (mass). Both quantities approach the asymptotic value $\hbarω/4$ in the large energy (mass) limit. The polarization per particle for fermions is always smaller than that for anti-fermions, whose ratio of fermions to anti-fermions also decreases with the chemical potential. The polarization per particle on the Cooper-Frye freeze-out hyper-surface can also be formulated and is consistent with the previous result of Becattini et al..

description: We present $β$-FeSe magnetotransport data, and describe them theoretically. Using a simplified microscopic model with two correlated effective orbitals, we determined the normal state electrical conductivity and Hall coefficient, using Kubo formalism. With model parameters relevant for Fe-chalcogenides, we describe the observed effect of the structural transition on the ab-plane electrical resistivity, as well as on the magnetoresistance. Temperature-dependent Hall coefficient data were measured at 16 Tesla, and their theoretical description improves upon inclusion of moderate electron correlations. We confirm the effect of the structural transition on the electronic structure, finding deformation-induced band splittings comparable to those reported in angle-resolved photoemission.

description: Wireless telephone speech is usually limited to the 300-3400 Hz band, which reduces its quality. There is thus a growing demand for wideband speech systems that transmit from 50 Hz to 8000 Hz. This paper presents an algorithm to generate wideband speech from narrowband speech using as low as 500 bits/s of side information. The 50-300 Hz band is predicted from the narrowband signal. A source-excitation model is used for the 3400-8000 Hz band, where the excitation is extrapolated at the receiver, and the spectral envelope is transmitted. Though some artifacts are present, the resulting wideband speech has enhanced quality compared to narrowband speech.

description: The time delay between the receptions of ultra-relativistic particles emitted simultaneously is a useful observable for both fundamental physics and cosmology. The expression of the delay when the particles travel through an arbitrary spacetime has been derived recently by Fanizza et al., using a particular coordinate system and self-consistent assumptions. The present article shows that this formula enjoys a simple physical interpretation: the relative velocity between two ultra-relativistic particles is constant. This result reveals an interesting kinematical property of general relativity, namely that the tidal forces experienced by ultra-relativistic particles in the direction of their motion are much smaller than those experienced orthogonally to their motion.

description: PROMETHEUS is the Precursor of a new liquid rocket Engine family designed for low-cost, flexibility and reusability. This Project, undertaken through cooperation between CNES and Ariane Group, entered in the ESA Future Launcher Preparatory Programme after the ESA Ministerial Conference in December 2016, with Germany, Italy, Belgium, Sweden and Switzerland joining France in the support of this Programme. The aim of PROMETHEUS programme is to design, produce, and test an advanced cost-effective 100tons class LOX/LCH4 reusable Engine. This Engine targets flexibility in operation through variable thrust, multiple ignitions, compatibility to main and upper stage operation, and minimized ground operations before and after flight. To reach those ambitious objectives, a design-to-cost approach is mandatory, as well as innovative technologies and advanced industrial capabilities; among the major levers, there are the extensive recourse to Additive J\\1anufacturing for the production of engine components, the introduction of a full electric command system and the on-board Rocket Engine Computer (REEC) for Engine management and monitoring. In addition, Prometheus programme promotes the application of Agile and Frugal methodologies to get maximum profit in product innovation and value creation in operation. This paper presents the global status of Prometheus advancements and gives a specific insight regarding the last and upcoming milestones: 2021 first engine delivery, 2022 engines tests realization on Themis lG and engine test campaign preparation for 2023 at PS in DLR Lampoldhausen.
Effectiveness of educational intervention on breast cancer knowledge and breast self-examination among female university students in Bangladesh: a pre-post quasi-experimental study
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Cancer diagnosis

description: Breast cancer is a global health issue and a leading cause of death among women. Early detection through increased awareness and knowledge on breast cancer and breast cancer screening is thus crucial. The aim of the present study was to assess the effect of an educational intervention program on breast cancer knowledge and the practice of breast self-examination among young female students of a university in Bangladesh. Methods: A quasi-experimental (pre-post) study design was conducted at Jahangirnagar University in Bangladesh. Educational information on breast cancer and breast self-examination (BSE), demonstration of BSE procedure and leaflets were distributed among 400 female students after obtaining written informed consent. The stepwise procedures of BSE performance were demonstrated with images. Pre-intervention and 15 days post-intervention assessments were conducted to assess the changes in knowledge on breast cancer and practices of BSE. Mc-Nemar’s tests and paired sampled t-tests were performed to investigate the differences between pre- and post-test stages. Results: A total of 400 female university students aged 18-26 years were included in the sample. Significant changes were found in knowledge and awareness about breast cancer and BSE practices after the educational intervention. The significant differences were measured in the mean scores of pre-test vs. post-test: breast cancer symptoms (2.99 ± 1.05 vs. 6.35 ± 1.15; p < 0.001), risk factors (3.35 ± 1.19 vs. 7.56 ± 1.04; p < 0.001), treatment (1.79 ± 0.90 vs. 4.63 ± 0.84; p < 0.001), prevention (3.82 ± 1.32 vs. 7.14 ± 1.03; p < 0.001), screening of breast cancer (1.82 ± 0.55 vs. 3.98 ± 0.71; p < 0.001) and process of BSE (1.57 ± 1.86 vs. 3.94 ± 0.93; p < 0.001). Likewise, a significant percentage of change in BSE practices was obtained between pre-test and post-test (21.3% vs. 33.8%; p < 0.001). Conclusions: Study findings confirm that the study population had inadequate awareness and knowledge at baseline which was improved significantly after educational intervention. A nationwide roll-out with community-based interventions is recommended for the female population in both rural and urban areas.
The social basis of vaccine questioning and refusal: A qualitative study employing bourdieu’s concepts of ‘capitals’ and ‘habitus’
Creators: name: Ward, Paul
Publisher: name: Torrens University Australia
Year: 2023
Subjects: Social determinants of health

description: This article is an in-depth analysis of the social nature of vaccine decision-making. It employs the sociological theory of Bourdieu and Ingram to consider how parents experience non-vaccination as a valued form of capital in specific communities, and how this can affect their decision-making. Drawing on research conducted in two Australian cities, our qualitative analysis of new interview data shows that parents experience disjuncture and tugs towards ‘appropriate’ forms of vaccination behavior in their social networks, as these link to broader behaviors around food, school choices and birth practices. We show how differences emerge between the two cities based on study designs, such that we are able to see some parents at the center of groups valorizing their decisions, whilst others feel marginalized within their communities for their decisions to vaccinate. We draw on the work of philosopher Mark Navin to consider how all parents join epistemic communities that reward compliance and conformity with the status quo and consider what this means for interventions that seek to influence the flow of pro-vaccine information through vaccine-critical social groups.

description: We consider the possibility to produce a bouncing universe in the framework of scalar-tensor gravity when the scalar field has a nonconformal coupling to the Ricci scalar. We prove that bouncing universes regular in the future with essentially the same dynamics as for the conformal coupling case do exist when the coupling deviates slightly from it. This is found numerically for more substantial deviations as well. In some cases however new features are found like the ability of the system to leave the effective phantom regime.

description: A good description of the electronic structure of BiS$_{2}$-based superconductors is essential to understand their phase diagram, normal state and superconducting properties. To describe the first reports of normal state electronic structure features from angle resolved photoemission spectroscopy (ARPES) in LaO$_{1-x}$F$_{x}$BiS$_{2}$, we used a minimal microscopic model to study their low energy properties. It includes the two effective tight-binding bands proposed by Usui et al [Phys.Rev.B 86, 220501(R)(2012)], and we added moderate intra- and inter-orbital electron correlations related to Bi-($p_{Y}$, $p_{X}$) and S-($p_{Y}$, $p_{X}$) orbitals. We calculated the electron Green's functions using their equations of motion, which we decoupled in second-order of perturbations on the correlations. We determined the normal state spectral density function and total density of states for LaO$_{1-x}$F$_{x}$BiS$_{2}$, focusing on the description of the k-dependence, effect of doping, and the prediction of the temperature dependence of spectral properties. Including moderate electron correlations, improves the description of the few experimental ARPES and soft X-ray photoemission data available for LaO$_{1-x}$F$_{x}$BiS$_{2}$. Our analytical approximation enabled us to calculate the spectral density around the conduction band minimum at $\vec{k}_{0}=(0.45π,0.45π)$, and to predict the temperature dependence of the spectral properties at different BZ points, which might be verified by temperature dependent ARPES.

description: With only the tree level operator, the decay of $Λ_b\rightarrow pK$ is predicted to be one order smaller than the experimental data. The QCD penguin effects should be taken into account. In this paper, we explore the one-loop QCD corrections to the decay of $Λ_b\to pK$ within the framework of QCD factorization approach. For the baryon system, the diquark approximation is adopted. The transition hadronic matrix elements between $Λ_b$ and $p$ are calculated in the light front quark model. The branching ratio of $Λ_b\rightarrow pK$ is predicted to be about $4.85\times 10^{-6}$ which is consistent with experimental data $(4.9\pm 0.9)\times 10^{-6}$. The CP violation is about 5\% in theory.

Some Classes of Gravitational Shock Waves from Higher Order Theories of Gravity

description: We study the gravitational shock wave generated by a massless high energy particle in the context of higher order gravities of the form $F(R,R_{μν}R^{μν},R_{μναβ}R^{μναβ})$. In the case of $F(R)$ gravity, we investigate the gravitational shock wave solutions corresponding to various cosmologically viable gravities, and as we demonstrate the solutions are rescaled versions of the Einstein-Hilbert gravity solution. Interestingly enough, other higher order gravities result to the general relativistic solution, except for some specific gravities of the form $F(R_{μν}R^{μν})$ and $F(R,R_{μν}R^{μν})$, which we study in detail. In addition, when realistic Gauss-Bonnet gravities of the form $R+F(\mathcal{G})$ are considered, the gravitational shock wave solutions are identical to the general relativistic solution. Finally, the singularity structure of the gravitational shock waves solutions is studied, and it is shown that the effect of higher order gravities makes the singularities milder in comparison to the general relativistic solutions, and in some particular cases the singularities seem to be absent.

A case study of Clinical Nursing Facilitator performance judgement
Creators: name: Simes, Tracey
Publisher: name: CQUniversity
Year: 2023
Subjects: Professional education and training

description: This study investigated the process whereby clinical facilitators (CFs) make judgements about a nursing student's performance during clinical placement. Previous studies have reported that many CFs lack confidence in their ability to judge nursing students’ performance. This lack of confidence is problematic as poor-performing students can progress through the study program, resulting in graduates not ready to function as independent registered nurses. This thesis details an interpretive–constructivist case study that investigated the performance judgement of CFs within an Australian clinical placement environment. A clinical facilitator (CF) is defined for this study as an educator within a health care facility employed to supervise six or more students simultaneously. Semi-structured interviews were conducted in 2018 with 15 CFs who had at least six months of experience facilitating nursing students within the Australian health care context. The research question guiding this study was: How do clinical facilitators construct judgements about a student nurse's performance in clinical placement? Guided by the Braun and Clarke thematic data analysis, the researcher identified six thematic actions that are foundational to CFs' performance judgements, which are described using participants’ own words. The cognitive continuum theory was used to frame the study and interpret findings. The study findings first reveal that the judgement of CFs is inherently reflexive due to the recursive development of new knowledge that occurs through interactions between self and other key players. Second, this judgement is also idiosyncratic, resulting in a wide variation in the accuracy of performance judgements. Third, CFs recognising and responding constructively to their feelings of uncertainty is a vital and valid component of performance judgement that needs to be investigated further. This study has contributed to the body of knowledge about how clinical facilitators make performance judgements, which may assist in the future production of work-ready graduates.
Wearable knee exoskeleton-assisted postural balance enhancement for industrial workers
Creators: name: Sreenivasan, Gayatri
Publisher: name: No Publisher Supplied
Year: 2023

description: Construction workers are highly susceptible to falls and contribute a large percentage of fatal occupational incidents. Workers use repeated gait sequences involving gaits like kneeling and squatting, which lead to knee osteoarthritis, joint injuries, and muscular dysfunction. These work-related musculoskeletal disorders (WMSDs) increase worker susceptibility to falls. Furthermore, several construction-related jobs place the worker at high elevations. The high-elevation workplace environment is stressful and challenging due to height perception, auditory stimulation, strong gusts of wind, and limited area for movement. The combined effect of environmental perturbations and WMSDs provokes worker postural instability and threatens worker safety. In order to prevent such WMSDs in industrial workers, wearable knee assistive robots (WKARs) have been developed. This thesis aims to facilitate effective balance controller design to equip existing WKARs that prevent WMSDs with balance-enhancing capabilities. Initially, biomechanical factors such as knee joint stiffness, postural sway, and body acceleration are explored in the presence of WKARs. While knee joint stiffness is a prominent parameter choice for WKAR control, there are considerable practical challenges associated with experimentally measuring knee joint stiffness due to the muted nature of quiet stance. In this work, the obstacles are carefully considered and circumvented to pave the way for future stiffness-based WKAR controllers for balance enhancement. Next, the neural balance strategy that humans employ during a relaxed stance is examined. In order to provide a representation of the neural mechanisms that influence upright balance, a linear quadratic regulator-controlled triple inverted pendulum model is built. Physiologically plausible controller parameters are assigned that allow the underlying neural balance strategy to be examined. Intersection point height-based frequency analysis is used in conjunction with the constructed model to study the effects of WKARs and cognitive loading on quiet stance. Lastly, an evaluation methodology that uses neurophysiological tasks in an immersive environment is proposed to assess the benefits and limitations of WKARs for specific occupational environments. The assessment is created with the goal of standardizing WKAR testing procedures in the future. In conclusion, this thesis investigates biomechanical and neurological factors affecting knee-based balance control and provides a foundation for advanced occupational WKAR development and assessment.

description: High-quality collections of Type II supernova (SN) light curves are scarce because they evolve for hundreds of days, making follow-up observations time consuming and often extending over multiple observing seasons. In light of these difficulties, the diversity of SNe II is not fully understood. Here we present ultraviolet and optical photometry of 12 SNe II monitored by the Las Cumbres Observatory Global Telescope Network (LCOGT) during 2013-2014, and compare them with previously studied SNe having well-sampled light curves. We explore SN II diversity by searching for correlations between the slope of the linear light-curve decay after maximum light (historically used to divide SNe II into IIL and IIP) and other measured physical properties. While SNe IIL are found to be on average more luminous than SNe IIP, SNe IIL do not appear to synthesize more 56Ni than SNe IIP. Finally, optical nebular spectra obtained for several SNe in our sample are found to be consistent with models of red supergiant progenitors in the 12-16 Msun range. Consequently, SNe IIL appear not to account for the deficit of massive red supergiants as SN II progenitors.

description: Gravitational waves are a prediction of general relativity, and with ground-based detectors now running in their advanced configuration, we will soon be able to measure them directly for the first time. Binaries of stellar-mass black holes are among the most interesting sources for these detectors. Unfortunately, the many different parameters associated with the problem make it difficult to promptly produce a large set of waveforms for the search in the data stream. To reduce the number of templates to develop, one must restrict some of the physical parameters to a certain range of values predicted by either (electromagnetic) observations or theoretical modeling. In this work we show that "hyperstellar" black holes (HSBs) with masses $30 \lesssim M_{\rm BH}/M_{\odot} \lesssim 100$, i.e black holes significantly larger than the nominal $10\,M_{\odot}$, will have an associated low value for the spin, i.e. $a<0.5$. We prove that this is true regardless of the formation channel, and that when two HSBs build a binary, each of the spin magnitudes is also low, and the binary members have similar masses. We also address the distribution of the eccentricities of HSB binaries in dense stellar systems using a large suite of three-body scattering experiments that include binary-single interactions and long-lived hierarchical systems with a highly accurate integrator, including relativistic corrections up to ${\cal O}(1/c^5)$. We find that most sources in the detector band will have nearly zero eccentricities. This correlation between large, similar masses, low spin and low eccentricity will help to accelerate the searches for gravitational-wave signals.

description: Using the Herschel Space Observatory we have observed a representative sample of 87 powerful 3CR sources at redshift z < 1. The far-infrared (FIR, 70-500 micron) photometry is combined with mid-infrared (MIR) photometry from the Wide-Field Infrared Survey Explorer (WISE) and catalogued data to analyse the complete spectral energy distributions (SEDs) of each object from optical to radio wavelength. To disentangle the contributions of different components, the SEDs are fitted with a set of templates to derive the luminosities of host galaxy starlight, dust torus emission powered by active galactic nuclei (AGN) and cool dust heated by stars. The level of emission from relativistic jets is also estimated, in order to isolate the thermal host galaxy contribution. The new data are in line with the orientation-based unification of high-excitation radio-loud AGN, in that the dust torus becomes optically thin longwards of 30 micron. The low excitation radio galaxies and the MIR weak sources represent MIR- and FIR-faint AGN population different from the high-excitation MIR-bright objects; it remains an open question whether they are at a later evolutionary state or an intrinsically different population. The derived luminosities for host starlight and dust heated by star formation are converted to stellar masses and star formation rates (SFR). The host-normalized SFR of the bulk of the 3CR sources is low when compared to other galaxy populations at the same epoch. Estimates of the dust mass yield a 1--100 times lower dust/stellar mass ratio than for the Milky Way, indicating that these 3CR hosts have very low levels of interstellar matter explaining the low level of star formation. Less than 10% of the 3CR sources show levels of star formation above those of the main sequence of star forming galaxies.

description: We examine the distribution of the [O/Fe] abundance ratio in stars across the Galactic disk using H-band spectra from the Apache Point Galactic Evolution Experiment (APOGEE). We minimize systematic errors by considering groups of stars with similar atmospheric parameters. The APOGEE measurements in the Sloan Digital Sky Survey Data Release 12 reveal that the square root of the star-to-star cosmic variance in the oxygen-to-iron ratio at a given metallicity is about 0.03-0.04 dex in both the thin and thick disk. This is about twice as high as the spread found for solar twins in the immediate solar neighborhood and the difference is probably associated to the wider range of galactocentric distances spanned by APOGEE stars. We quantify the uncertainties by examining the spread among stars with the same parameters in clusters; these errors are a function of effective temperature and metallicity, ranging between 0.005 dex at 4000 K and solar metallicity, to about 0.03 dex at 4500 K and [Fe/H]= -0.6. We argue that measuring the spread in [O/Fe] and other abundance ratios provides strong constraints for models of Galactic chemical evolution.

description: PROMETHEUS is the Precursor of a new liquid rocket Engine family designed for low-cost, flexibility and reusability. This Project, undertaken through cooperation between CNES and Ariane Group, entered in the ESA Future Launcher Preparatory Programme after the ESA Ministerial Conference in December 2016, with Germany, Italy, Belgium, Sweden and Switzerland joining France in the support of this Programme. The aim of Prometheus project is to design, produce, and test an advanced low-cost 100-tons class reusable Engine. This cost competitive Engine, designed for reusability, for flexibility in operation through variable thrust, multiple ignitions, compatibility to main and upper stage operation, and minimized ground operations before and after flight. In early January 2021, following the visit of the French President Emmanuel Macron, an agreement preparatory to the testing of the new Prometheus rocket engine at the Vernon site in Normandy was signed. This agreement, funded through the space component of the France Relance recovery plan in support to French industry, allowed to accelerate and de-risk the PROMETHEUS test schedule whilst settling an agile stage test stand in ArianeGroup Vernon test area, the PF20-B, in an optimised synergy with the Future Launchers Preparatory Programme ofESA This paper presents the genesis of PROMETHEUS tests on PF20-B / THEMIS-lBench in Vernon, the status of PROMETHEUS France Re lance test campaign and gives insight to the stage test stand which was defined on frugal basis, taking maximum benefit of the elements made available by THEMIS stage first demonstrations.

description: In the interstellar medium of galaxies and the intracluster gas of galaxy clusters, the charged particles making up cosmic rays are moving almost exclusively along (but not across) magnetic field lines. The resulting anisotropic transport of cosmic rays in the form of diffusion or streaming not only affects the gas dynamics but also rearranges the magnetic fields themselves. The coupled dynamics of magnetic fields and cosmic rays can thus impact the formation and evolution of galaxies and the thermal evolution of galaxy clusters in critical ways. Numerically studying these effects requires solvers for anisotropic diffusion that are accurate, efficient, and robust, requirements that have proven difficult to satisfy in practice. Here, we present an anisotropic diffusion solver on an unstructured moving mesh that is conservative, does not violate the entropy condition, allows for semi-implicit time integration with individual timesteps, and only requires solving a single linear system of equations per timestep. We apply our new scheme to a large number of test problems and show that it works as well or better than previous implementations. Finally, we demonstrate for a numerically demanding simulation of the formation of an isolated disk galaxy that our local time-stepping scheme reproduces the results obtained with global time-stepping at a fraction of the computational cost.
