description: Since September 11th, there have been massive increases in personal, commercial, and governmental expenditures on anti-terrorism strategies, as well as a proliferation of programs designed to fight terrorism. These increases in spending and program development have focused attention on the most significant and central policy question related to these interventions: Do these programs work? To explore research evidence regarding this question, we conducted a Campbell systematic review on counter-terrorism strategies to determine the scope and strength of evaluation research in this area. In the course of our review, we discovered that there is an almost complete absence of evaluation research on counter-terrorism strategies. From over 20,000 studies we located on terrorism, we found only seven which contained moderately rigorous evaluations of counterterrorism programs. We conclude that there is little scientific knowledge about the effectiveness of most counter-terrorism interventions. Further, from the evidence we were able to locate, it appears that some evaluated interventions either didn’t work or sometimes increased the likelihood of terrorism and terrorism-related harm. The findings of this review dramatically emphasize the need for government leaders, policy makers, researchers, and funding agencies to include and insist on evaluations of the effectiveness of these programs in their agendas. These agendas would include identifying ways to overcome methodological and data challenges often associated with terrorism research, increasing funding to evaluate existing programs through methodologically rigorous evaluation designs, and paying attention to existing evaluations of programs when implementing them. Further, programs should be assessed to establish if they cause more harm than good or if they create unanticipated consequences.

description: Recent observations of topological spin textures brought spintronics one step closer to new magnetic memories. Nevertheless, the existence of Skyrmions, as well as their stabilization, require very specific intrinsic magnetic properties which are usually fixed in magnets. Here we address the possibility to dynamically control their intrinsic magnetic interactions by varying the strength of a high-frequency laser field. It is shown that drastic changes can be induced in the antiferromagnetic exchange interactions and the latter can even be reversed to become ferromagnetic, provided the direct exchange is already non-negligible in equilibrium as predicted, for example, in Si doped with C, Sn, or Pb adatoms. In the presence of Dzyaloshinskii-Moriya interactions, this enables us to tune features of ferromagnetic Skyrmions such as their radius, making them easier to stabilize. Alternatively, such topological spin textures can occur in frustrated triangular lattices. Then, we demonstrate that a high-frequency laser field can induce dynamical frustration in antiferromagnets, where the degree of frustration can subsequently be tuned suitably to drive the material toward a Skyrmionic phase.

description: We investigate competing insulating phases in nearly metallic zigzag carbon nanotubes, under conditions where an applied magnetic flux approximately closes the single particle gap in one valley. Recent experiments have shown that an energy gap persists throughout magnetic field sweeps where the single-particle picture predicts that the gap should close and reopen. Using a bosonic low-energy effective theory to describe the interplay between electron-electron interactions, spin-orbit coupling, and magnetic field, we obtain a phase diagram consisting of several competing insulating phases that can form in the vicinity of the single-particle gap closing point. We characterize these phases in terms of spin-resolved charge polarization densities, each of which can independently take one of two possible values consistent with the mirror symmetry of the system, or can take an intermediate value through a spontaneous mirror symmetry breaking transition. In the mirror symmetry breaking phase, adiabatic changes of the orbital magnetic flux drive charge and spin currents along the nanotube. We discuss the relevance of these results to recent and future experiments.
Childhood trauma as a vulnerability to psychopathology after subsequent trauma in adulthood

description: Exposure to trauma is common; however not everyone develops posttraumatic stress disorder (PTSD) or depression after a traumatic event. Prior trauma in childhood trauma has been linked with several detrimental outcomes in adulthood. This thesis aims to explore the vulnerability of adults with a history of childhood trauma to psychopathology following exposure to a subsequent trauma. The thesis begins with a review of the relevant literature, including a discussion of prevalence of trauma, the impact of trauma, a presentation of cognitive models of PTSD and evidence for them, a discussion of risk factors for development of PTSD and depression, and the impact of trauma in children in light of developmental theories and research evidence. The thesis then presents the findings of two studies focusing on the vulnerabilities of childhood trauma. The first study addresses whether individuals with a history of childhood trauma are at an increased risk of developing PTSD or depression after a subsequent trauma in adulthood. It further assesses the contribution of other vulnerability factors frequently linked to childhood trauma to this risk, such as frequency of prior trauma, prior social support or prior psychopathology. The results showed that adults with a history of childhood trauma were more likely to experience posttraumatic stress and depressive symptoms after a subsequent trauma compared to adults with adolescent trauma, adulthood trauma only or no trauma history. The results further showed that those with childhood trauma experienced a greater number of prior traumas, had received less social support prior to the trauma and had more prior psychopathology compared to the other groups. Findings indicated that this group’s increased risk of psychopathology after a subsequent trauma was predominantly through these vulnerability factors. The second study used structural equation modelling (SEM) to investigate the PTSD symptom response pathways to PTSD in those with a history of childhood trauma and those without a history of childhood trauma to compare if they differ. Two distinct PTSD subtypes have recently been suggested: a dissociative/avoidant and a re-experiencing/arousal subtype. This study investigated whether these subtypes represent response pathways after a trauma, and whether these response pathways differ between adult trauma survivors with and without a history of child trauma. Results showed that individuals with a history of childhood trauma utilise a predominantly avoidant response leading to PTSD, while those without childhood trauma utilise a predominantly arousal and re-experiencing response. Finally, these results and their implications are discussed.

description: This thesis work focuses on non-reactive solute transport modeling of the akaki wellfield for two selected groundwater contaminants (chloride & fluoride) for the 25 operating boreholes administered by Addis Ababa Water & Sewerage Authority (AAWSA). The work is conducted based on laboratory analysis of groundwater samples from selected boreholes and based on historical data of the wellfield boreholes. The widespread use of chemical products, coupled with the disposal of large volumes of waste materials, poses the potential for widely distributed groundwater contamination. Because such contaminations can pose a serious threat to public health, prediction of the degree of contamination by appropriate numerical modeling tools is vital to aware the end user from possible risks. Mathematical models solved numerically are the subject of this thesis work focusing on conservative solute transport in the Akaki well field. Chloride & fluoride ions predictive modeling of the wellfield for the next ten years (2007-2017) is made first by calibrating the model input parameters using the available historical solute concentration data for selected boreholes at various periods. For calibration purpose, initial solute concentration was taken as 3 mg/l for chloride and 0.51 mg/l for fluoride and MATLAB simulation of chloride & fluoride ion concentration is done. The simulation results show that while chloride concentrations in the wellfield get increased; fluoride, however, is getting decreasing through out all of the boreholes in the wellfield. This is in agreement with the actual observed pattern of solute load of the wellfield revealing chloride is being introduced in to the wellfield by one or more mechanisms somewhere in the vicinity of the akaki river catchment (ARC) while fluoride is not. Keywords: aquifers, breakthrough curves, initial conditions, boundary conditions, calibration, prediction, conservative contaminant transport, hydraulic conductivity, porosity.

description: Spin gapless semiconductors exhibit a finite band gap for one spin channel and closed gap for other spin channel, emerged as a new state of magnetic materials with a great potential for spintronic applications. The first experimental evidence for the spin gapless semiconducting behavior was observed in an inverse Heusler compound Mn2CoAl. Here, we report a detailed investigation of the crystal structure and anomalous Hall effect in the Mn2CoAl using experimental and theoretical studies. The analysis of the high-resolution synchrotron x-ray diffraction data shows anti-site disorder between Mn and Al atoms within the inverse Heusler structure. The temperature-dependent resistivity shows semiconducting behavior and follows Mooijs criteria for disordered metal. Scaling behavior of the anomalous Hall resistivity suggests that the anomalous Hall effect in the Mn2CoAl is primarily governed by intrinsic mechanism due to the Berry curvature in momentum space. The experimental intrinsic anomalous Hall conductivity (AHC) is found to be 35 S/cm, which is considerably larger than the theoretically predicted value for ordered Mn2CoAl. Our first-principle calculations conclude that the anti-site disorder between Mn and Al atoms enhances the Berry curvature and hence the value of intrinsic AHC, which is in a very well agreement with the experiment.

description: The modern conception of phases of matter has undergone tremendous developments since the first observation of topologically ordered states in fractional quantum Hall systems in the 1980s. In this paper, we explore the question: How much detail of the physics of topological orders can in principle be observed using state of the art technologies? We find that using surprisingly little data, namely the toric code Hamiltonian in the presence of generic disorders and detuning from its exactly solvable point, the modular matrices -- characterizing anyonic statistics that are some of the most fundamental finger prints of topological orders -- can be reconstructed with very good accuracy solely by experimental means. This is a first experimental realization of these fundamental signatures of a topological order, a test of their robustness against perturbations, and a proof of principle -- that current technologies have attained the precision to identify phases of matter and, as such, probe an extended region of phase space around the soluble point before its breakdown. Given the special role of anyonic statistics in quantum computation, our work promises myriad applications both in probing and realistically harnessing these exotic phases of matter.

The role of TGF-β superfamily members: TGF-β1 and activin A in early folliculogenesis
Creators: name: Cossigny (Rosairo), Davina Annaliz Fiona
Publisher: name: Monash University
Year: 2017
Subjects: Uncategorized

description: Members of the TGF-β superfamily have been implicated in numerous roles throughout the process of folliculogenesis. They are expressed by oocytes, granulosa cells and theca cells and oversee follicle recruitment, growth, steroidogenesis, apoptosis, ovulation and luteinization (Knight and Glister, 2003). The importance of this family is well recognized and has formed the foundation of the research conducted throughout this PhD. To assess the role of members of the TGF-β superfamily play in folliculogenesis, more specifically from primordial to preantral follicle development, a model system of cultured whole ovaries was employed. The role of TGF-β1 and activin A in follicle development within the ovary was investigated. In the first instance, TGF-β1 was administered to cultured whole rat ovaries, with or without FSH. Follicle counts were performed and atresia was assessed. At the completion of these investigations the impact of activin A with or without FSH, on follicle development was assessed. Follicle counts were performed and an observation into atresia was made. The postnatal rat model employed has proven beneficial in investigating early follicle development as it utilizes the defined follicle populations that first appear in the ovary of the rodent. It allowed growth of these ovaries containing growing follicles with the addition of specific growth factors in order to assess the impact they may or may not be having on folliculogenesis (see Chapters 2 and 3). Additionally, Chapter 4 details the investigations made into the transgenic human follistatin (tghFST) mouse model. Follistatin (FST) is a monomeric protein that like inhibin, was initially discovered for its ability to suppress FSH activity (Robertson et al., 1987; Ueno et al., 1987). It is now well recognized that FST is a high-affinity activin-binding protein that can modulate the biological availability of activin (Nakamura et al., 1990). The two major isoforms, follistatin 288 (FST288) and follistatin 315 (FST315) result from alternative splicing of FST mRNA. Utilizing a novel “knock-in” approach of the tghFST genes, this mouse model expresses human FST288 and human FST315, providing a unique opportunity to decipher the differential roles each isoform may play in ovarian follicle development and growth. Whole organ histological and gene expression profiles were investigated. These studies have provided direct evidence for individual roles for healthy follicle development and growth. Further analysis will shed light into the interactions FST has with members of the TGF-β superfamily and its involvement in the pathway to female organogenesis. Ovarian follicle maturation is highly specialized involving various signalling factors, of which several belong to the TGF-β superfamily. Understanding how members of the TGF-β superfamily influence ovarian follicle development will greatly enhance our knowledge in ovarian and reproductive biology.

description: Producing high-brightness and high-charge (>100 pC) electron bunches at blowout regime requires ultrashort laser pulses with high fluence. The effects of laser pulse heating of the copper photocathode are analyzed in this paper. The electron and lattice temperature is calculated using an improved two-temperature model, and an extended Dowell-Schmerge model is employed to calculate the thermal emittance and quantum efficiency. A time-dependent growth of the thermal emittance and the quantum efficiency is observed. For a fixed amount of charge, the projected thermal emittance increases with decreasing laser radius, and this effect should be taken into account in laser optimization at blowout regime. Moreover, laser damage threshold fluence is simulated, showing that the maximum local fluence should be less than 40 mJ/cm^2 to prevent damage to the cathode.

description: Artificial Neural Networks (ANNs) have been successfully used in various nuclear engineering applications, such as predicting reactor physics parameters within reasonable time and with a high level of accuracy. Despite this success, they cannot provide information about the model prediction uncertainties, making it difficult to assess ANN prediction credibility, especially in extrapolated domains. In this study, Deep Neural Networks (DNNs) are used to predict the assembly axial neutron flux profiles in the SAFARI-1 research reactor, with quantified uncertainties in the ANN predictions and extrapolation to cycles not used in the training process. The training dataset consists of copper-wire activation measurements, the axial measurement locations and the measured control bank positions obtained from the reactor's historical cycles. Uncertainty Quantification of the regular DNN models' predictions is performed using Monte Carlo Dropout (MCD) and Bayesian Neural Networks solved by Variational Inference (BNN VI). The regular DNNs, DNNs solved with MCD and BNN VI results agree very well among each other as well as with the new measured dataset not used in the training process, thus indicating good prediction and generalization capability. The uncertainty bands produced by MCD and BNN VI agree very well, and in general, they can fully envelop the noisy measurement data points. The developed ANNs are useful in supporting the experimental measurements campaign and neutronics code Verification and Validation (V&V).

His method is based on fast polynomial arithmetic techniques and runs in time $\widetilde{O}(N^{1/4})$, which has been state of the art for the last forty years. In this paper, we will combine Strassen's approach with a babystep-giantstep method to improve the currently best known bound by a superpolynomial factor. The runtime complexity of our algorithm is of the form \[ \widetilde{O}\left(N^{1/4}\exp(-C\log N/\log\log N)\right). \]

What Does a One-Bit Quanta Image Sensor Offer?

Subjects: subject: Image and Video Processing (eess.IV)

description: The one-bit quanta image sensor (QIS) is a photon-counting device that captures image intensities using binary bits. Assuming that the analog voltage generated at the floating diffusion of the photodiode follows a Poisson-Gaussian distribution, the sensor produces either a ``1'' if the voltage is above a certain threshold or ``0'' if it is below the threshold. The concept of this binary sensor has been proposed for more than a decade, and physical devices have been built to realize the concept. However, what benefits does a one-bit QIS offer compared to a conventional multi-bit CMOS image sensor? Besides the known empirical results, are there theoretical proofs to support these findings? The goal of this paper is to provide new theoretical support from a signal processing perspective. In particular, it is theoretically found that the sensor can offer three benefits: (1) Low-light: One-bit QIS performs better at low-light because it has a low read noise, and its one-bit quantization can produce an error-free measurement. However, this requires the exposure time to be appropriately configured. (2) Frame rate: One-bit sensors can operate at a much higher speed because a response is generated as soon as a photon is detected. However, in the presence of read noise, there exists an optimal frame rate beyond which the performance will degrade. A Closed-form expression of the optimal frame rate is derived. (3) Dynamic range: One-bit QIS offers a higher dynamic range. The benefit is brought by two complementary characteristics of the sensor: nonlinearity and exposure bracketing. The decoupling of the two factors is theoretically proved, and closed-form expressions are derived.

description: The rich absorption spectra of Sun-like stars are enticing probes for variations in the fine-structure constant, $α$, which gauges the strength of electromagnetism. While individual line wavelengths are sensitive to $α$, they are also sensitive to physical processes in the stellar atmospheres, which has precluded their use so far. Here we demonstrate a new, differential approach using solar twins: velocity separations between close pairs of transitions are compared across stars with very similar physical properties, strongly suppressing astrophysical and instrumental systematic errors. We utilise 423 archival exposures of 18 solar twins from the High-Accuracy Radial velocity Planetary Searcher (HARPS), in which calibration errors can be reduced to $\lesssim$3 m/s. For stars with $\approx$10 high signal-to-noise ratio spectra ($\ge$200 per pixel), velocity separations between pairs are measured with $\approx$10 m/s statistical precision. A companion paper assesses a range of systematic error sources using 130 stars, with a greater range of stellar parameters, providing accurate corrections for astrophysical effects and a residual, intrinsic star-to-star scatter of 0-13 m/s. Within these uncertainties, we find no evidence for velocity separation differences in 17 transition pairs between solar twins. In a second companion paper, this is found to limit local ($\lesssim$50 pc) variations in $α$ to $\approx$50 parts per billion, $\sim$2 orders of magnitude less than other Galactic constraints.

description: Molecular vibroic spectroscopy, where the transitions involve non-trivial Bosonic correlation due to the Duschinsky Rotation, is strongly believed to be in a similar complexity class as Boson Sampling. At finite temperature, the problem is represented as a Boson Sampling experiment with correlated Gaussian input states. This molecular problem with temperature effect is intimately related to the various versions of Boson Sampling sharing the similar computational complexity. Here we provide a full description to this relation in the context of Gaussian Boson Sampling. We find a hierarchical structure, which illustrates the relationship among various Boson Sampling schemes. Specifically, we show that every instance of Gaussian Boson Sampling with an initial correlation can be simulated by an instance of Gaussian Boson Sampling without initial correlation, with only a polynomial overhead. Since every Gaussian state is associated with a thermal state, our result implies that every sampling problem in molecular vibronic transitions, at any temperature, can be simulated by Gaussian Boson Sampling associated with a product of vacuum modes. We refer such a generalized Gaussian Boson Sampling motivated by the molecular sampling problem as Vibronic Boson Sampling.

description: Sun-like stars are a new probe of variations in the fine-structure constant, $α$, via the solar twins approach: velocity separations of close pairs of absorption lines are compared between stars with very similar stellar parameters, i.e. effective temperature, metallicity and surface gravity within 100K, 0.1 dex and 0.2 dex of the Sun's values. Here we assess possible systematic errors in this approach by analysing $\gtrsim$10,000 archival exposures from the High-Accuracy Radial velocity Planetary Searcher (HARPS) of 130 stars covering a much broader range of stellar parameters. We find that each transition pair's separation shows broad, low-order variations with stellar parameters which can be accurately modelled, leaving only a small residual, intrinsic star-to-star scatter of 0-33 m/s (average $\approx$7 m/s, $\approx$10$^{-4}$Å at 5000Å). This limits the precision available from a single pair in one star. We consider potential systematic errors from a range of instrumental and astrophysical sources (e.g. wavelength calibration, charge transfer inefficiency, stellar magnetic activity, line blending) and conclude that variations in elemental abundances, isotope ratios and stellar rotational velocities may explain this star-to-star scatter. Finally, we find that the solar twins approach can be extended to solar analogues - within 300K, 0.3 dex and 0.4 dex of the Sun's parameters - without significant additional systematic errors, allowing a much larger number of stars to be used as probes of variation in $α$, including at much larger distances.

Δαπάνες υγείας

description: Εισαγωγή: Ο τομέας της υγείας, ίσως, είναι από τους πιο σύνθετους τομείς στη δημόσια ζωή μιας χώρας, καθώς η παροχή υπηρεσιών υγείας υψηλού επιπέδου αντανακλά στοιχεία ευημερίας και ανάπτυξης αλλά παράλληλα απαιτεί υψηλή οργάνωση και μεγάλη κατανάλωση οικονομικών και ανθρώπινων πόρων. Οι παράγοντες που σχετίζονται με την διαχρονική αύξηση της δαπάνης υγείας είναι η αύξηση του πληθυσμού, το προσδόκιμο επιβίωσης, η δημογραφική γήρανση, το εισόδημα των πολιτών και η τεχνολογική εξέλιξη στον τομέα της υγείας. Ταυτόχρονα, όμως, με τη διαχρονική αύξηση της δαπάνης υγείας, λαμβάνονται μέτρα και προτείνονται παρεμβάσεις που σκοπό έχουν να ελέγξουν την εκτόξευση της ιατροφαρμακευτικής δαπάνης. Σκοπός: Η παρούσα διπλωματική εργασία διερευνά την εξέλιξη της φαρμακευτικής δαπάνης στο Π.Γ.Ν. ΑΤΤΙΚΟΝ τη δεκαετία 2012-2022 και πως αυτή μεταβάλλεται στη διάρκεια των ετών, εξαρτώμενη από ένα πλήθος παραγόντων. Μέθοδος: Η μεθοδολογική προσέγγιση για την παρακολούθηση της φαρμακευτικής δαπάνης στο Αττικό Νοσοκομείο συνίσταται στη λήψη συγκεντρωτικών στοιχείων σχετικά με τις δαπάνες φαρμάκων και τις ποσότητες αυτών . Τα στοιχεία υπέστησαν ίδια επεξεργασία αναλύοντας τις κυριότερες κατηγορίες φαρμάκων, την ποσοστιαία μεταβολή ανά έτος και την επίδραση τους στη φαρμακευτική δαπάνη. Αποτελέσματα: Τα τελευταία χρόνια η συνεχής αύξηση της υγειονομικής δαπάνης είναι γεγονός και αποτελεί αντικείμενο μελέτης της επιστημονικής κοινότητας. Οι κατηγορίες φαρμάκων με την μεγαλύτερη επιδραστικότητα στην εξέλιξη της φαρμακευτικής δαπάνης στο Αττικό Νοσοκομείο είναι τα ογκολογικά, τα αντιρετροϊκά, του υψηλού κόστους και τα αντιβιοτικά φάρμακα. Συμπεράσματα: Η κατανόηση του μηχανισμού συσχέτισης μεταξύ των παραγόντων που προκαλούν αύξηση στη δαπάνη υγείας βοηθά στο να αποσαφηνίσουμε τις ανάγκες του συστήματος υγείας και οδηγεί στην πιο συνετή χρήση των υπηρεσιών.

description: The aim of this thesis was to research patient satisfaction and experience in Saudi Arabian hospitals. A secondary aim was to develop a validated patient experience tool and associated benchmarking protocols for Saudi Arabia that was based on the Victorian Patient Satisfaction Monitor (VPSM) in Australia. The VPSM is a tool that has been used in Victorian hospitals to monitor patient experience for the past ten years. The thesis commences with a comprehensive narrative review of the relevant research literatures. The main study within the thesis involved a large survey of recently discharged patients from Saudi Hospitals. Survey data were obtained from seventeen hospitals in Riyadh region in Saudi Arabia from a sample frame of 2125 patients. Of the 2125 distributed questionnaires, 1700 were returned and 1604 were found to be adequate for the data analysis, yielding a net response rate of 75.5 per cent. Analysis of the study data showed that the adapted VPSM instrument was a valid and reliable tool amongst Saudi hospital patient respondents. Cronbach alpha values for all of the six VPSM indices and the summary overall care index were found to be satisfactory. The reliability of the six indices ranged from a high of 0.954 for treatment information to a low of 0.849 for access and admission. The results show considerable variability across the patient groups from the surveyed hospitals. The patients’ mean overall care index score was found to vary considerably across the sampled hospitals (2.53 to 4.17). Among the six sub-indices, the lowest average score was achieved on the physical environment index (2.95) and the highest mean score was achieved on the treatment information index (3.61). The impacts of age, gender and remoteness of the hospital upon index scores were systematically modeled within the study. The modeling showed that there was an interaction effect between age and gender on patients’ satisfaction level. Moreover, the remoteness of the hospital significantly affected patients’ responses in terms of the access and admission index, general patient information index, physical and environmental index and discharge and follow-up index. Based on these results, it is recommended that the Ministry of Health of Saudi Arabia adopts the adapted VPSM for measuring patients’ satisfaction and experiences in all Saudi public hospitals. The expected results for VPSM adoption in Saudi Arabia will be an enhanced healthcare delivery system and more effective health resources utilization.
