description: Orexin (OX) neurons originating in the lateral hypothalamus (LH) are ideally positioned to modulate reward processing as they form connections with several key brain regions known to be involved in the reward pathway. Consistent with these findings, a growing number of studies have implicated the OX system in modulating the rewarding properties of several drugs of abuse, including ethanol (EtOH). However, the role of the OX system in excessive binge-like EtOH intake remains relatively unexplored. Here, we assessed changes in OX immunoreactivity (IR) in the hypothalamus following repeated cycles of binge-like EtOH drinking and assessed the participation of the OX-1 receptor (OX1R) in binge-like EtOH consumption.

description: We report a detection of water vapor in the protoplanetary disk around DoAr 44 with the Texas Echelon Cross Echelle Spectrograph --- a visitor instrument on the Gemini north telescope. The DoAr 44 disk consists of an optically thick inner ring and outer disk, separated by a dust-cleared 36 AU gap, and has therefore been termed "pre-transitional". To date, this is the only disk with a large inner gap known to harbor detectable quantities of warm (T=450 K) water vapor. In this work, we detect and spectrally resolve three mid-infrared pure rotational emission lines of water vapor from this source, and use the shapes of the emission lines to constrain the location of the water vapor. We find that the emission originates near 0.3 AU --- the inner disk region. This characteristic region coincides with that inferred for both optically thick and thin thermal infrared dust emission, as well as rovibrational CO emission. The presence of water in the dust-depleted region implies substantial columns of hydrogen (>10^{22} cm-2) as the water vapor would otherwise be destroyed by photodissociation. Combined with the dust modeling, this column implies a gas/small-dust ratio in the optically thin dusty region of >1000. These results demonstrate that DoAr 44 has maintained similar physical and chemical conditions to classical protoplanetary disks in its terrestrial-planet forming regions, in spite of having formed a large gap.

title: On Transonic Wing Shock Unsteadiness
Creators: name: Masini, Luke
Publisher: name: University of Liverpool Repository
Year: 2021

description: Aircraft wings in high-speed flight experience detrimental flow unsteadiness. Its interaction with the flexible wing structure and resulting dynamic loads are addressed in the certification specifications which stipulate a cruise design point free from any structural vibration and buffeting. One such flow unsteadiness is shock buffet and its inherent dynamics near the onset of unsteadiness are addressed herein. Specifically, an extensive experimental dataset of a large aircraft wing geometry and complementary scale-resolving simulations are scrutinised. Whilst the experimental dataset comprises a wide range of flow conditions from pre-onset to established buffet for Mach numbers between 0.70 and 0.84 and four configurations, the primary focus is on the clean wing at the design Mach number of 0.80 and Reynolds number of approximately 3.6 million (based on mean aerodynamic chord). Key to this study are highly-resolved unsteady surface pressure data acquired by dynamic pressure-sensitive paint, in addition to conventional data from pressure transducers and a wing-root strain gauge. To match the experiment and thereby aiding a richer elucidation of the flow physics, detached-eddy simulations are performed using two subgrid length-scale definitions, motivated by the challenge of simulating separating and reattaching shallow shear layers. Modal decomposition techniques are instrumental in pursuing a thorough data analysis. Experimentally, two distinct phenomena in shock-buffet conditions are identified. First, low-frequency shock unsteadiness with characteristic Strouhal numbers between 0.05 and 0.15 (where Strouhal number is based on mean aerodynamic chord and reference freestream velocity) propagates pressure disturbances predominantly inboard. Importantly, this coherent unsteadiness is exclusive to the experiment and even occurs before the strain gauge detects structural buffeting. Second, a broadband higher-frequency behaviour for Strouhal numbers between 0.2 and 0.5 is characterised by three-dimensional cellular patterns describing localised pockets of shear-layer pulsation synchronised with an outboard-propagating shock oscillation. Dominant modal features capturing this characteristic signature show striking similarity between experiment and simulation, detailing the pertinent attributes of shock-buffet unsteadiness whilst contrasting it with the first phenomenon. These findings will help clarify these edge-of-the-envelope flow phenomena and ultimately inform future wing design.

description: Self-accelerating solutions in massive gravity provide explicit, calculable examples that exhibit the general interplay between superluminality, the well-posedness of the Cauchy problem, and strong coupling. For three particular classes of vacuum solutions, one of which is new to this work, we construct the conformal diagram for the characteristic surfaces on which isotropic stress-energy perturbations propagate. With one exception, all solutions necessarily possess spacelike characteristics, indicating perturbative superluminality. Foliating the spacetime with these surfaces gives a pathological frame where kinetic terms of the perturbations vanish, confusing the Hamiltonian counting of degrees of freedom. This frame dependence distinguishes the vanishing of kinetic terms from strong coupling of perturbations or an ill-posed Cauchy problem. We give examples where spacelike characteristics do and do not originate from a point where perturbation theory breaks down and where spacelike surfaces do or do not intersect all characteristics in the past light cone of a given observer. The global structure of spacetime also reveals issues that are unique to theories with two metrics: in all three classes of solutions, the Minkowski fiducial space fails to cover the entire de Sitter spacetime allowing worldlines of observers to end in finite proper time at determinant singularities. Characteristics run tangent to these surfaces requiring {\it ad hoc} rules to establish continuity across singularities.

description: This thesis presents a group of studies published, submitted or in preparation, and other research study projects approved by Ethics Committees. Its general aim is to explore how patients with MDRDs may show dysfunctions in body perception. It is composed of two main parts. PART I presents a general overview of body perception mechanisms and perceptual dysfunctions in MDRDs. More particularly, Chapter I offers a systematic review of the literature dedicated to the questions and knowledge gaps highlighted in the introduction. PART II approaches the relationship between BPDs and neuropathic pain through an overview of the neurophysiological mechanisms described in the literature dedicated to the role of neuropathic pain in ?phantom perceptions?. A special focus has been placed on dysfunctions of the so-called small-fibers. Finally, Chapters II-V will address the hypotheses guiding the subsequent studies and research projects, which explore phenomena of bodily illusions in two categories of MDRDs: fibromyalgic patients and subjects with chronic low back pain affected by failed back surgery. A series of studies has been conducted during the three-year period of PhD training (2017-2019), while other research projects were proposed for future development. Research lines promoted has been planned and conducted from different perspectives, adopting a variety of methodologies in order to cover the complexity of body perception phenomena in chronic painful MDRDs.

description: This paper describes a method for the recovering of software architectures from a set of similar (but unrelated) software products in binary form. One intention is to drive refactoring into software product lines and combine architecture recovery with run time binary analysis and existing clustering methods. Using our runtime binary analysis, we create graphs that capture the dependencies between different software parts. These are clustered into smaller component graphs, that group software parts with high interactions into larger entities. The component graphs serve as a basis for further software product line work. In this paper, we concentrate on the analysis part of the method and the graph clustering. We apply the graph clustering method to a real application in the context of automation / robot configuration software tools.

Neuroimaging techniques

description: The advancements in neuroimaging techniques, predominantly magnetic resonance imaging (MRI) and computed tomography (CT) scans, have undeniably reformed the clinical neuroscience landscape by escalating the accuracy and reliability of both diagnosis and prognosis in the realm of intricate neurological disorders. However, the quest to further augment these advancements continues, igniting a compelling interest in the conception and integration of sophisticated machine learning models which potentiate swift and precise three-dimensional reconstruction of neuronal particles, thereby aiding medical practitioners in formulating efficacious therapeutic interventions. To actualize this motive, the present thesis proposed an innovative methodology, underpinned by an interpretive simulation which in turn is a corollary of the accrued model assessment results. The methodological design of this investigative endeavor amalgamates robust imaging pipelines such as generative adversarial networks (GANs) with precision-calibrated deep learning networks, featuring a meticulously designed densenet-41-based backbone in tandem with CornerNet. For the pragmatic application of this scientific inquiry, a selected sample set derived from the Medical Image Computing and Computer Assisted Intervention (MICCAI) 2020 dataset, embodying brain MRI images, was exploited. Moreover, insights from the RSNA-MICCAI Brain Tumor Radiogenomic Classification challenge were assimilated, focusing on predicting MGMT promoter methylation status, an essential biomarker in brain tumor treatments. The experimental design delineated 100 images as the training set, complemented by an auxiliary set of 10 images demarcated for validation purposes. Findings from this research exude a striking classification efficacy of 91.2% for the densenet-41-based backbone and 89.8% for CornerNet, ascertaining the hitherto diagnostic precision of this methodology. In the interest of fortifying classification accuracy, a Time-Lapse analysis was incorporated for sequential scrutiny, alongside the induction of a Long Short-Term Memory (LSTM) layer responsible for processing voxels in a sequence, thereby augmenting the precision of tracking from one voxel to another. In conclusion, the outcomes derived from this pioneering study corroborate that the novel approach substantially optimizes both velocity and precision in the diagnosis and prognosis of neurological disorders. The empirical evidence garnered aligns impeccably with the relevant academic and clinical benchmarks, providing a robust platform for quantitative analysis and facilitating the classification of an array of brain tumor types, potentially leading to transformative outcomes in neuro-oncology treatment paradigms.

L?analisi comparata si estende alle strutture incaricate di predisporne l'attuazione, ossia la Spes nel caso della propaganda democristiana e il Servizio Informazioni della Presidenza del Consiglio nel caso, invece, della comunicazione istituzionale del governo. Di entrambi gli enti vengono ricostruite origine ed evoluzione in relazione, rispettivamente, al modello organizzativo di partito e al quadro istituzionale antecedente e coevo. Eleggendo quale fonte privilegiata il materiale audiovisivo prodotto nel corso degli anni, l'analisi del contenuto della propaganda politica e della comunicazione istituzionale individua alcuni temi specifici e ricorrenti all'interno di una narrazione che si dispiega fra la ricostruzione post-bellica e l'affermarsi e consolidarsi dello sviluppo economico. In conclusione, si dedica una riflessione relativa alle modalit� di fruizione delle fonti audiovisive della Spes e del Servizio Informazioni e alle pratiche di valorizzazione attuate dai soggetti conservatori.

description: Experimental demonstrations of entangled quantum images produced through parametric downconversion have so far been confined to studying two photon correlations. Here we show that multiphoton correlations between quantum images are accessible experimentally and exhibit many new features including being sensitive to the phase of the bi-photon wavefunction. As a concrete example, we consider a modification of existing quantum imaging experiments in which the CCD cameras are moved out of focus, provide detailed analytical predictions for the resulting 4 photon intereferences, and support these by numerical simulations. The proposed experiment can also be interpreted as entanglement swapping: Bob's photons are initially unentangled, but the joint detection of Alice's photons projects Bob's photons onto an entangled state. The general approach proposed here can be extended to other quantum optics experiments involving high dimensional entanglement.

description: Binge drinking during adolescence is associated with increased risk for developing alcohol use disorders (AUDs); however, the neural mechanisms underlying this liability are unclear. In this study, we sought to determine if binge-drinking alters expression or phosphorylation of two molecular mechanisms of neuroplasticity, calcium/calmodulin dependent kinase II alpha (CaMKIIα) and the GluA1 subunit of AMPA receptors (AMPAR) in addiction-associated brain regions. We also asked if activation of CaMKIIα-dependent AMPAR activity escalates binge-like drinking.

description: We study positive kernels on $X\times X$, where $X$ is a set equipped with an action of a group, and taking values in the set of $\mathcal A$-sesquilinear forms on a (not necessarily Hilbert) module over a $C^*$-algebra $\mathcal A$. These maps are assumed to be covariant with respect to the group action on $X$ and a representation of the group in the set of invertible ($\mathcal A$-linear) module maps. We find necessary and sufficient conditions for extremality of such kernels in certain convex subsets of positive covariant kernels. Our focus is mainly on a particular example of these kernels: a completely positive (CP) covariant map for which we obtain a covariant minimal dilation (or KSGNS construction). We determine the extreme points of the set of normalized covariant CP maps and, as a special case, study covariant quantum observables and instruments whose value space is a transitive space of a unimodular type-I group. As an example, we discuss the case of instruments that are covariant with respect to a square-integrable representation.

description: BACKGROUND: Methylome-wide association (MWAS) studies present a new way to advance the search for biological correlates for alcohol use. A challenge with methylation studies of alcohol involves the causal direction of significant methylation-alcohol associations. One way to address this issue is to combine MWAS data with genomewide association study (GWAS) data.

METHODS: Here, we combined MWAS and GWAS results for alcohol use from 619 individuals. Our MWAS data were generated by next-generation sequencing of the methylated genomic DNA fraction, producing over 60 million reads per subject to interrogate methylation levels at ~27 million autosomal CpG sites in the human genome. Our GWAS included 5,571,786 single nucleotide polymorphisms (SNPs) imputed with 1000 Genomes.

RESULTS: When combining the MWAS and GWAS data, our top finding was a region in an intron of CNTN4 (p = 2.55 × 10(-8) ), located between chr3: 2,555,403 and 2,555,524, encompassing SNPs rs1382874 and rs1382875. This finding was then replicated in an independent sample of 730 individuals. We used bisulfite pyrosequencing to measure methylation and found significant association with regular alcohol use in the same direction as the MWAS (p = 0.021). Rs1382874 and rs1382875 were genotyped and found to be associated in the same direction as the GWAS (p = 0.008 and p = 0.009). After integrating the MWAS and GWAS findings from the replication sample, we replicated our combined analysis finding (p = 0.0017) in CNTN4.

CONCLUSIONS: Through combining methylation and SNP data, we have identified CNTN4 as a risk factor for regular alcohol use.

This makes it possible to describe the asymptotic growth of polynomial functions on S in terms of combinatorial data. We extend our earlier work to compute the ring of bounded functions in this setting and discuss applications to positive polynomials and the moment problem. Complete results are obtained in special cases, like sets defined by binomial inequalities. We also show that the wild behaviour of certain examples constructed by Krug and by Mondal-Netzer cannot occur in a toric setting.

description: Studying compact star binaries and their mergers is integral to determining progenitors for observable transients. Today, compact-star mergers are typically studied via state-of-the-art computational fluid dynamics codes. One such numerical technique, Smoothed Particle Hydrodynamics (SPH), is frequently chosen for its excellent mass, energy, and momentum conservation. The natural treatment of vacuum and the ability to represent highly irregular morphologies make SPH an excellent tool for the study of compact-star binaries and mergers. For many scenarios, including binary systems, the outcome of simulations is only as accurate as the initial conditions. For SPH, it is essential to ensure that the particles are distributed regularly, representing the initial density profile but without long-range correlations. Particle noise in the form of high-frequency local motion and low-frequency global dynamics must be damped out. Damping the latter can be as computationally intensive as the actual simulation. We discuss a new and straightforward relaxation method, Halted-Pendulum Relaxation (HPR), to remove global oscillation modes of SPH particle configurations. In combination with effective external potentials representing gravitational and orbital forces, we show that HPR has an excellent performance in efficiently relaxing SPH particles to the desired density distribution and removing global oscillation modes. We compare the method to frequently used relaxation approaches and test it on a white dwarf binary model at its Roche lobe overflow limit. We highlight the importance of our method in achieving accurate initial conditions and its effect on achieving circular orbits and realistic accretion rates when compared with other general relaxation methods.

description: Che il populismo nell?ultimo decennio attraversi un momento di particolare fortuna � fuor di dubbio, molti leader populisti sono stati eletti e molti partiti etichettati allo stesso modo sono nati e hanno da subito ottenuto risultati sorprendenti. Tutti questi ?nuovi? esempi di populismo hanno ben poco in comune tra loro, se non l?opposizione ad un?�lite che sembra superare i confini nazionali ed estendersi in ogni continente. L?elaborato mira ad evidenziare le cause alla base dell?attuale fortuna del populismo, osservandolo in relazione ai modelli all?�lite che si sono susseguiti nella modernizzazione riflessiva, con particolare attenzione all?�lite neo-liberale, considerata dominante nella societ� contemporanea. Per raggiungere questo obbiettivo il rapporto tra populismo e mutamento sociale � osservato attraverso un?ottica il pi� ampia possibile, che comprende alcune delle pi� note definizioni politiche e sociali del populismo ed alcune descrizioni della societ� post-industriale. L?elaborato si compone di cinque capitoli ognuno dei quali aggiunge un tassello alla descrizione dell?attuale fortuna del populismo. Dapprima si analizza il concetto di populismo al fine di proporre una nuova definizione che permetta di rapportarlo al mutamento sociale. Il lavoro considera il populismo come un insieme di strategie atte a costruire un?ideologia che movimenta la parte di societ� con una mentalit� opposta a quella dell?�lite. Allo stesso tempo si presenta il momento pi� propizio per l?affermazione del populismo in corrispondenza dell?ideologizzazione, che avviene quando l?�lite assolutizza alcune posizioni sociali facendole corrispondere ad elementi di distinzione della posizione sociale. All?analisi del populismo segue quella del risentimento, inteso come processo mentale alla base della propensione ad accogliere la propaganda populista. Nei capitoli che seguono si descrivono le propensioni sociali del populismo dagli anni Settanta ad oggi in una doppia chiave di lettura: la prima � ciclica e osserva l?ideologizzazione dell?�lite all?apice del suo corso; la seconda � progressiva e guarda al crescente sviluppo del risentimento. La diffusione del populismo contemporaneo � dunque osservata come risultante dal declino dell?�lite neo-liberale dopo aver raggiunto il suo apice e dalle contraddizioni del modello politico e sociale del neo-liberalismo che propende alla diffusione del risentimento.
title: The Effect of Economic and Individual Variables on Retirement Decisions

description: Pension systems in several countries have begun to show a lack of efficiency and sustainability, which motivates governments to investigate which factors cause this loss of balance. It is commonly known that traditional pension systems where active workers finance the pensions of retired workers as pay-as-you-go (PAYGO) have a strong dependence on the demographic structure of countries. Here is where factors such as the increase in life expectancy and a decrease in birth rate, have an impact on this balance. Several measures aimed at keeping the sustainability of pension schemes are focused on the modification of variables, such as retirement age and contribution of workers, to maintain the solvency of the system. Some articles have gone beyond and studied how macroeconomic and individual variables can influence the decision of early retirement. This study contributes to written literature about the effect of macroeconomic variables on retirement decisions. It expands in the inclusion of oil prices as an important variable that can affect retirement, specifically in countries that export oil and whose economy depends on this income. Additionally, this study presents an innovative model of artificial intelligence developed for the industry to predict the early retirement of individuals. This model takes into account economic factors and individuals characteristics to create an alert system that constantly is fed as new data is generated. This research has a strong impact in recent years. Oil prices have had several fluctuations, mainly downward, affecting the economy of countries in different ways. Early retirement is one example of the consequences in the economy caused by the fluctuating oil prices. Currently, there is no machine-learning model implemented internally in insurance companies or government institutions to track early retirement. The alert system allows controlling early retirement at a company level. The governments and administrators of pensions should be aware of this.
Fully achromatic nulling interferometer (FANI) for high SNR exoplanet characterization

description: Space-borne nulling interferometers have long been considered as the best option for searching and characterizing extra-solar planets located in the habitable zone of their parent stars. Solutions for achieving deep starlight extinction are now numerous and well demonstrated. However they essentially aim at realizing an achromatic central null in order to extinguish the star. In this communication is described a major improvement of the technique, where the achromatization process is extended to the entire fringe pattern. Therefore higher Signal-to-noise ratios (SNR) and appreciable simplification of the detection system should result. The basic principle of this Fully achromatic nulling interferometer (FANI) consists in inserting dispersive elements along the arms of the interferometer. Herein this principle is explained and illustrated by a preliminary optical system design. The typical achievable performance and limitations are discussed and some initial tolerance requirements are also provided

title: The Sustainability of Chinese Pay-As-You-Go Pension System in Urban Areas

description: A pay-as-you-go (PAYG) pension system requires a balance between the benefits paid to pensioners and the contributions made by active workers. The decline in fertility rates and the increase in longevity in China will lead to a substantial increase in the old-age dependency ratio, raising serious concerns about the long-term sustainability of the Chinese pension system. This thesis provides the first estimate of the sustainability of the Chinese PAYG pension system in urban areas and is based on two actuarial balance methodologies. The first is the Swedish solvency ratio, which is based on verifiable facts. The second is the United States’ actuarial balance indicator, which takes into account projected demographic and economic structures. Both methodologies show that the Chinese pension system, in its current form, is unsustainable. Two factors, namely the one-child policy and the urbanization process, that affect the sustainability of the Chinese pension system are analysed. Population projections under different demographic structures are provided using the cohort component method, and an automatic balancing mechanism is designed in order to restore the sustainability of this pension system. The main finding is that the one-child policy is harmful to the system’s sustainability. Furthermore, all scenarios studied show there is an urgent need to introduce mechanisms that will guarantee long-term sustainability of the system. The analysis of the urbanization process shows that demographic changes due to rural-urban migration will have an enormous impact on the Chinese PAYG pension system. Contrary to the current public hypothesis that a huge inflow of a working-age population will restore the demographic balance between contributors and pensioners, the rapid urbanization process will result in a higher old-age dependency ratio after 2050. Overall, urbanization worsens the long-term sustainability of the Chinese pension system.

description: We present new NuSTAR and Chandra observations of NGC 3393, a galaxy reported to host the smallest separation dual AGN resolved in the X-rays. While past results suggested a 150 pc separation dual AGN, three times deeper Chandra imaging, combined with adaptive optics and radio imaging suggest a single, heavily obscured, radio-bright AGN. Using VLA and VLBA data, we find an AGN with a two-sided jet rather than a dual AGN and that the hard X-ray, UV, optical, NIR, and radio emission are all from a single point source with a radius <0.2". We find that the previously reported dual AGN is most likely a spurious detection resulting from the low number of X-ray counts (<160) at 6-7 keV and Gaussian smoothing of the data on scales much smaller than the PSF (0.25" vs. 0.80" FWHM). We show that statistical noise in a single Chandra PSF generates spurious dual peaks of the same separation (0.55$\pm$0.07" vs. 0.6") and flux ratio (39$\pm$9% vs. 32% of counts) as the purported dual AGN. With NuSTAR, we measure a Compton-thick source (NH=$2.2\pm0.4\times10^{24}$ cm$^{-2}$) with a large torus half-opening angle, θ=79 which we postulate results from feedback from strong radio jets. This AGN shows a 2-10 keV intrinsic to observed flux ratio of 150. Using simulations, we find that even the deepest Chandra observations would severely underestimate the intrinsic luminosity of NGC 3393 above z>0.2, but would detect an unobscured AGN of this luminosity out to high redshift (z=5).
