description: We estimate the two-point correlation function in redshift space of the recently compiled HIPASS neutral hydrogen (HI) sources catalogue, which if modeled as a power law, $ξ(r)=(r_{0}/r)^γ$, the best-fitting parameters for the HI selected galaxies are found to be $r_{0}=3.3 \pm 0.3 h^{-1}$ Mpc with $γ=1.38 \pm 0.24$. Fixing the slope to its universal value $γ=1.8$, we obtain $r_{0}= 3.2\pm 0.2 h^{-1}$ Mpc. Comparing the measured two point correlation function with the predictions of the concordance cosmological model, we find that at the present epoch the HI selected galaxies are anti-biased with respect to the underlying matter fluctuation field with their bias value being $b_{0}\simeq 0.68$. Furthermore, dividing the HI galaxies into two richness subsamples we find that the low mass HI galaxies have a very low present bias factor ($b_{0}\simeq 0.48$), while the high mass HI galaxies trace the underlying matter distribution as the optical galaxies ($b_{0}\simeq 1$). Using our derived present-day HI galaxy bias we estimate their redshift space distortion parameter, and correct accordingly the correlation function for peculiar motions. The resulting real-space correlation length is $r^{\rm re}_{0}=1.8 \pm 0.2 h^{-1}$Mpc and $r^{\rm re}_{0}=3.9 \pm 0.6 h^{-1}$Mpc for the low and high mass HI galaxies, respectively. The low-mass HI galaxies appear to have the lowest correlation length among all extragalactic populations studied to-date. Also, we have correlated the IRAS-PSCz reconstructed density field, smoothed over scales of 5$h^{-1}$ Mpc, with the positions of the HI galaxies, to find that indeed the HI galaxies are typically found in negative overdensity regions ($δρ/ρ_{\rm PSCz} \mincir 0$).

description: We investigate the effects of non-commutative geometry on the topological aspects of gauge theory using a non-perturbative formulation based on the twisted reduced model. The configuration space is decomposed into topological sectors labeled by the index nu of the overlap Dirac operator satisfying the Ginsparg-Wilson relation. We study the probability distribution of nu by Monte Carlo simulation of the U(1) gauge theory on 2d non-commutative space with periodic boundary conditions. In general the distribution is asymmetric under nu -> -nu, reflecting the parity violation due to non-commutative geometry. In the continuum and infinite-volume limits, however, the distribution turns out to be dominated by the topologically trivial sector. This conclusion is consistent with the instanton calculus in the continuum theory. However, it is in striking contrast to the known results in the commutative case obtained from lattice simulation, where the distribution is Gaussian in a finite volume, but the width diverges in the infinite-volume limit. We also calculate the average action in each topological sector, and provide deeper understanding of the observed phenomenon.

Etica ed evoluzionismo: la proposta di Marc Hauser
Creators: name: Pilloni, Irene
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2013

description: Le recenti scoperte nell’ambito della psicologia evoluzionistica potrebbero offrire una risposta al dibattito sull’origine evoluzionistica della facoltà morale dell’Homo sapiens. In passato, il tentativo di spiegare il comportamento morale a partire dalla teoria dell’evoluzione è stato intrapreso dal padre fondatore dell’evoluzionismo Charles Darwin, successivamente da T.H. Huxley e da H. Spencer e infine dal sociobiologo E. Wilson a metà degli anni ‘70 del Novecento. Oggi questa impresa è stata ereditata dallo psicologo evoluzionista Marc Hauser, le cui indagini prendono avvio da un’analogia tra facoltà morale e facoltà linguistica. Questa analogia gli consente di affermare che la pluralità di codici morali adottati dagli uomini nelle differenti culture dipende da un numero limitato di principi morali, nello stesso modo in cui la varietà di lingue con cui gli uomini si esprimono, dipende da un numero limitato di principi linguistici universali. Dunque, sembrerebbe che l’evoluzione biologica abbia plasmato dei principi morali universali e uniformi che si presentano costanti in tutti gli uomini a prescindere dalla loro appartenenza culturale. Come vadano intesi i principi morali universali e quale rapporto intercorre tra di essi e i vari codici morali sarà l’argomento di questo saggio, il quale tenterà di analizzare la proposta di Marc Hauser all’interno della cornice dei rapporti tra etica ed evoluzionismo.

Tides, Differential Rotation, and Eclipsing Binaries

description: A poster for the Cool Stars 20.5 Virtual Conference. Based on this paper: Jermyn, Tayar, & Fuller 2020: https://academic.oup.com/mnras/article/491/1/690/5607798 Abstract: Over time, tides synchronize the rotation periods of stars in a binary system to the orbital period. However, if the star exhibits differential rotation, then only a portion of it can rotate at the orbital period, so the rotation period at the surface may not match the orbital period. The difference between the rotation and orbital periods can therefore be used to infer the extent of the differential rotation. We use a simple parametrization of differential rotation in stars with convective envelopes in circular orbits to predict the difference between the surface rotation period and the orbital period. Comparing this parametrization to observed eclipsing binary systems, we find that in the surface convection zones of stars in short-period binaries there is very little radial differential rotation, with |r∂rln Ω| < 0.02. This holds even for longer orbital periods, though it is harder to say which systems are synchronized at long periods, and larger differential rotation is degenerate with asynchronous rotation.
Probing inflation with large-scale structure data: the contribution of information at small scales

description: Upcoming full-sky large-scale structure surveys such as Euclid can probe the primordial Universe. Using the specifications for the Euclid survey, we estimate the constraints on the inflation potential beyond slow-roll. We use mock Euclid and Planck data from fiducial cosmological models using the Wiggly Whipped Inflation (WWI) framework, which generates features in the primordial power spectrum. We include Euclid cosmic shear and galaxy clustering, with two setups (Conservative and Realistic) for the non-linear cut-off. We find that the addition of Euclid data gives an improvement in constraints in the WWI potential, with the Realistic setup providing marginal improvement over the Conservative for most models. This shows that Euclid may allow us to identify oscillations in the primordial spectrum present at intermediate to small scales.

Key M.I.S. issues for management : an Eastern European perspective
Creators: name: Kiudorf, Enn
Publisher: name: University of British Columbia
Year: 2008

description: Considerable research has been done to identify issues of importance to MIS managers in North America and other Western countries. However, little is known about the priorities of Eastern European managers with respect to the application of information technologies (IT). IT will play an increasingly important role in Eastern Europe as organizations adapt to Western business practices. An understanding of managerial concerns is therefore useful for individuals and organizations with an interest in the economic transition and restructuring process of the region. This research aims to establish an understanding of MIS issues in an Eastern European organizational environment, and how these compare to the West. The study focuses on Estonia, which is judged to be an appropriately representative site for the research. A three round Delphi methodology was used to elicit the issues of importance from Estonian MIS managers and the research findings suggest a significantly distinct set of priorities. The managerial issues that have dominated the North American IS scene are of comparatively little importance; instead, the top issues for Eastern European managers are primarily technological concerns.

The step drift resulting from atomic evaporation and/or deposition is explicitly included in our model. A linear stability analysis reveals several stability inversions as the evaporation rate varies, while a deposition flux is shown to have a stabilizing effect.

description: The Magnificent Seven have all been discovered by their exceptional soft X-ray spectra and high ratios of X-ray to optical flux. They all are considered to be nearby sources. Searching for similar neutron stars with larger distances, one expects larger interstellar absorption resulting in harder X-ray counterparts. Current interstellar absorption treatment depends on chosen abundances and scattering cross-sections of the elements as well as on the 3D distribution of the interstellar medium. After a discussion of these factors we use the comprehensive 3D measurements of the Local Bubble by Lallement et al. 2003 to construct two simple models of the 3D distribution of the hydrogen column density. We test these models by using a set of soft X-ray sources with known distances. Finally, we discuss possible applications for distance estimations and population synthesis studies.

title: A bioinformatic analysis of malaria host and pathogen genomics

description: Malaria is a significant global disease caused by infection with parasites of the Plasmodium genus, which resulted in an estimated 216 million cases and 445,000 deaths in 2016 alone. Co-evolution of Plasmodium parasites and their human hosts has shaped both genomes for thousands of years. In this thesis I describe my work identifying and characterising novel genomic variants and selection signals associated with host-pathogen interactions in malaria. For the parasite, analysis of the impact of sustained sulfadoxine/pyrimethamine (SP) use on the Malawian parasite population (n=220) lead to the identification of selection signals associated with SP resistance factors and a novel 436 bp gch1 promoter region duplication at near-fixation. Next a global approach to copy number variation discovery (n=3,110), based on short read sequencing, identified several novel and geographically specific variants including large 22.9 kbp duplications of crt in West Africa. Finally, an inversion discovery pipeline was developed for a long read based approach to inversion detection (n=17). This led to the identification of a novel ‘sandwich inversion’ of pi4k in a sample of GB4, similar to inversion-duplication of gch1 in Dd2. For human genetics within the context of malaria, I conducted a GWAS with a Tanzanian dataset (n=914) and identified novel protective associations, such as for IL-23R and IL-12RBR2. I also identified novel structural variants (SV) with a short-read sequencing based dataset of Tanzanian parent-child trios (n=234) identifying several novel SVs associated with blood antigen systems. Near-fixation deletions in SEC22B and BET1L were also identified, suggesting an impact on intracellular transportation. Genomic variation associated with host-pathogen interactions is diverse, and SVs represent one overlooked aspect that requires further investigation. Bioinformatic approaches can help identify novel variants but depend upon novel software development, such as those described within this thesis (e.g. SV-Pop).

title: A Cultural Adaptation of a Diabetes Self-Management Programme for Patients with Type 2 Diabetes Attending a Primary Health Care Centre in Saudi Arabia
Creators: name: Alabdulbaqi, D
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2019

description: Background: Self-management is an integral part of chronic disease management. Diabetes self-management programmes have shown to be effective. However, they are not standard practice in all high prevalence settings. For example, although the prevalence of Type 2 Diabetes in Saudi Arabia is 23%, such programmes have yet to be developed and deployed to serve this population. Self-management programmes are highly culturally and context specific, requiring substantial research and refinement to make them effective. Aim: To culturally adapt the Stanford Diabetes Self-Management Programme to be more relevant to patients with type 2 diabetes attending a primary health care centre in Saudi Arabia. Methods: A total of 39 participants were recruited from clinic settings to attend a six-week programme and their feedback was used to inform the adaptation. A qualitative study of this process and the experiences of diabetes was built into the programme. This consisted of non-participatory observations in a chronic disease clinic, informal meetings with a team of health care professional and a series of focus groups with participating patients to explore perceptions of the programme and barriers to self-management. These were audio-recorded, transcribed verbatim and thematically analysed. Results: Gender and social norms and roles, religion and reliance on Allah were the main themes emerging from the data. Conclusion: Adapting the evidence-based intervention through using a cultural adaptation framework was not fully successful. This is due to complexity of incorporating findings such as gender and gender roles into the adaptation and at the same time maintain fidelity of the original programme. The finding of this study suggests that content and messages of behaviour change intervention may benefit from being gender-specific, especially in Saudi Arabia. The study contributes to more understanding of barriers to self-management among Saudi patients.

description: In this paper we propose a general definition of secrecy for cryptographic protocols in the Dolev-Yao model. We give a sufficient condition ensuring secrecy for protocols where rules have encryption depth at most two, that is satisfied by almost all practical protocols. The only allowed primitives in the class of protocols we consider are pairing and encryption with atomic keys. Moreover, we describe an algorithm of practical interest which transforms a cryptographic protocol into a secure one from the point of view of secrecy, without changing its original goal with respect to secrecy of nonces and keys, provided the protocol satisfies some conditions. These conditions are not very restrictive and are satisfied for most practical protocols.

The Beta Cephei instability domain for the new solar composition and with new OP opacities

Publisher: name: arXiv

description: The recent revision of the solar chemical composition (Asplund, Grevesse and Sauval 2005)is characterized by about 40 per cent decrease of C, N, O, Ne, Ar abundances and by 20 percent decrease of Fe and some other metal abundances. We tested the effect of these modifications on the instability of Beta Cephei models. For the opacities, the newest OP data from the Opacity Project (Seaton 2005) were used. We show that the Beta Cephei instability domain in the Hertzsprung-Russel diagram, when computed with new data for Z=0.012 (revised solar value), is very similar to the instability domain computed earlier using the OPAL opacities for the older solar composition with Z=0.02. Almost all observed Beta Cephei variables are located within the instability domain. Two effects are responsible for stronger instability when using the new data: (i) Metal opacity bump in the OP case is located slightly deeper in the star than that in the OPAL case, which results in more effective driving; (ii) at a fixed Z value, the new Fe-group abundances are higher than the older ones because the Z value is determined mainly by the abundances of C, N, 0, and Ne.

description: We revisit the problem of electron transport through mesoscopic rings with spin-orbit (SO) interaction. In the well-known path-integral approach, the scattering states for a quasi-1D ring with quasi-1D leads can be expressed in terms of spinless electrons subject to a fictitious magnetic flux. We show that spin-dependent quantum-interference effects in small rings are strongest for spatially inhomogeneous SO interactions, in which case spin currents can be controlled by a small external magnetic field. Mesoscopic spin Hall effects in four-terminal rings can also be understood in terms of the fictitious magnetic flux.

For irreducible representations, a theorem of Prasad shows that the space of such periods has dimension at most 1, and is non-zero when a certain epsilon-factor condition holds. We give an extension of this result to a certain class of reducible representations (of Whittaker type), extending results of Harris--Scholl when A is the split algebra F x F x F.

description: The aim of the present thesis was the study of Aristotle’s prime matter, a term that was used in his works On Coming-To-Be and Passing-Away and Physics A’. Firstly, through a historical retrospective, we showed the reasoning of scholars about the primary matter of the universe, from the presocratic philosophers, like Thales, Pythagoreans and Atomists, to Aristotle. Furthermore, we examined and commented on specific ancient text passages, in which the Stageirites philosopher analyzed his thoughts and deepened on the issue in these writings. Then we tried to connect the Aristotle’s ancient Greek thought with the up to date Physical science and more specifically, with the Quantum Physics. In this field of Physics, we ascertained that according to new data from modern studies, it is proved that the doctrine of the Stageirites philosopher is indirectly confirmed, which is an extremely impressive and pioneering fact

The first part introduces the concept of the care of the elderly starting with antiquity and going through history in the texts of the Old and New Testaments, the patristic literature and the ecclesiastical texts up until to Byzantium. The case of Hariseio Nursing Home which has written a history of more than 100 years in the city of Thessaloniki, is then being examined. The structure is studied through the perspective of pastoral care and how this care can be applied to an elderly home unit. In this study we find that older care structures can be the appropriate environment for the development of pastoral care, harmoniously linked to their lives within them

description: Στην παρούσα μεταπτυχιακή διπλωματική εργασία γίνεται εκτίμηση των περιοχών σύγκλισης περιοδικών τροχιών στο γενικό πρόβλημα των τριών σωμάτων στο επίπεδο, όπου θεωρούμε δύο σώματα με μάζες m1<<1 και m2<<1 τα οποία κινούνται γύρω από ένα σώμα μάζας m0=1-m1-m2. Πρόβλημα τριών σωμάτων τέτοιου τύπου ονομάζεται πλανητικό πρόβλημα των τριών σωμάτων. Το μεγάλο σώμα το ονομάζουμε αστέρα και τα δύο μικρότερα πλανήτες. Οι επαναλαμβανόμενες σχετικές διαμορφώσεις των τριών σωμάτων μπορούν να συσχετιστούν με περιοδικές τροχιές σε ένα κατάλληλο περιστρεφόμενο πλαίσιο αναφοράς. Σε αυτό το πλαίσιο, το γενικό επίπεδο πρόβλημα τριών σωμάτων, το οποίο είναι το βασικό μας μοντέλο, περιορίζεται σε τρεις βαθμούς ελευθερίας. Εξετάζουμε τρεις οικογένειες περιοδικών τροχιών σε συντονισμό 2:1 και διαφορετικές μάζες, όταν τα σώματα κινούνται στο ίδιο επίπεδο. Η πρώτη οικογένεια αντιστοιχεί σε μάζες m1=0.001, m2=0.001 (m_1=m_2), η δεύτερη σε m1=0.001 και m2=0.0002 (m_1=5m_2) και η τρίτη σε m1=0.001 και m2=0.002 (m_1=1/2 m_2).Ο πλανήτης m1 είναι ο εσωτερικός πλανήτης και ο m2 ο εξωτερικός Υπολογίζουμε τους χάρτες σύγκλισης με σταθερή στροφορμή και με σταθερή ενέργεια. Επίσης ελέγχουμε τον αριθμό επαναλήψεων που απαιτούνται για την εύρεση των τροχιών οι οποίες συγκλίνουν στην τροχιά στόχο.
description: In this postgraduate diploma thesis, we evaluate the convergence regions of periodic orbits in the general problem of the three bodies, in which we consider two bodies with masses m1 << 1 and m2 << 1 which orbit around a mass body m0 = 1-m1- m2. The problem of three bodies of this type is called the planetary problem of the three bodies. The big body we call it “the star” and the two smaller “planets”. Repeated relative configurations of the three bodies can be associated with periodic trajectories in a suitable rotating reference frame. In this context, the general three-body problem, where all bodies moves on the same plane, which is the basic model, is reduced to three degrees of freedom. We examine three families of periodic orbits in 2: 1 resonance and different masses. The first family corresponds to masses m1 =0.001, m2 = 0.001 (m_1=m_2), the second to m1 = 0.001 and m2 = 0.0002 (m_1=5m_2) and the third to m1 = 0.001 and m2 = 0.002 (m_1=1/2 m_2). The planet m1 is the inner planet and m2 is the outer one. We calculate the convergence maps with constant spin and with constant energy. We also control the number of iterations required to find the trajectories that converge to the target track.

description: One of the plausible unification schemes in physics considers the observable universe to be a 4-dimensional surface (the "brane") embedded in a higher-dimensional curved spacetime (the "bulk"). In such braneworld gravity models with infinitely large extra dimensions, black holes evaporate fast through the emission of the additional gravitational degrees of freedom, resulting in lifetimes of stellar-mass black holes that are significantly smaller than the Hubble time. We show that the predicted evaporation rate leads to a change in the orbital period of X-ray binaries harboring black holes that is observable with current instruments. We obtain an upper limit on the rate of change of the orbital period of the binary A0620-00 and use it to constrain the asymptotic curvature radius of the extra dimension to a value comparable to the one obtained by table-top experiments. Furthermore we argue that any measurement of a period increase for low-mass X-ray binaries with a high mass ratio is evidence for new physics beyond general relativity and the standard model.

description: The properties of the type Ic supernova SN 1994I are re-investigated. This object is often referred to as a "standard SN Ic" although it exhibited an extremely fast light curve and unusually blue early-time spectra. In addition, the observations were affected by significant dust extinction. A series of spectral models are computed based on the explosion model CO21 (Iwamoto et al. 1994) using a Monte Carlo transport spectral synthesis code. Overall the density structure and abundances of the explosion model are able to reproduce the photospheric spectra well. Reddening is estimated to be E(B-V)=0.30 mag, a lower value than previously proposed. A model of the nebular spectrum of SN 1994I points toward a slightly larger ejecta mass than that of CO21. The photospheric spectra show a large abundance of iron-group elements at early epochs, indicating that mixing within the ejecta must have been significant. We present an improved light curve model which also requires the presence of 56Ni in the outer layers of the ejecta.

description: This dissertation examines the basic concepts of the dynamic systems and focuses on study of population in the aquatic world, which are solved by using difference equations. In summary, the paper is based on a bibliographic review and is divided into two main parts. The first part presents the theoretical background of the difference equations, a trait of which is that they take place at a discrete time, and emphasis is placed on non-linear difference equations. In the second part, reference is made to fishery and in particular to over-fishing, where problems related to the marine organisms are being studied. In particular, two non-linear difference equations are laid out that are regulated by the world population of Atlantic Cod-fish
title: Dissecting the CD8+ T cell responses to pre-erythrocytic malaria antigens

description: The pre-erythrocytic stages of malaria are the preliminary steps to a disease of massive global health importance. Following transmission of sporozoites by mosquito bite to a human host, a clinically silent period of parasite development in the liver preludes the harmful blood stages that characterise malarial infection. Creating a vaccine that targets these stages is a very attractive notion as it would prevent this burden of disease. Protection against the pre-erythrocytic stages has been shown to be dependent on CD8+ T cells. However, very few antigens that induce anti-Plasmodium CD8+ T cell responses have been identified, especially those expressed by the parasite when developing inside hepatocytes. Using mouse models, experimental genetics and bioinformatics tools, I present work that has progressed our understanding of CD8+ T cells induced in the preerythrocytic stages of malaria and assessed the ability of antigen-specific CD8+ T cells to protect against subsequent challenge following vaccination. I have investigated and compared the differences in CD8+ T cell responses to a sporozoite (Circumsporozoite Protein) and a vacuolar membrane liver stage protein (Upregulated in Infectious Sporozoites gene 4) and showed that despite a divergence in immunogenicity when immunising with radiation attenuated sporozoites, both types of antigen are equally protective when mice are vaccinated with viral vectors to induce large antigen-specific CD8+ T cell populations. The natural immunogenicity of the liver stage antigen does not improve when liver stage development is extended by using drug prophylaxis. Additionally, I have compared the protection induced by liver stage antigens expressed constitutively after hepatocyte invasion and those expressed only after at least 12 hours post invasion. I have shown that some protection can be induced by the mid-late expressed Liver Specific Proteins 1 and 2, suggesting that these antigens are effectively presented and recognised by CD8+ T cells. This highlights the potential for the incorporation of liver stage antigens into next-generation malaria vaccines. 4 Additionally, I have investigated the role of the immunodominant CD8+ T cell epitope of Circumsporozoite Protein and showed that a significant level of protection is mediated by CD8+ T cells specific for this epitope. Nonetheless, following multiple immunisations with a parasite lacking this epitope, sterile protection can still be achieved, suggesting other antigens are important for parasite-induced protection. Thus, finally I go on to identify a number of novel CD8+ T cell epitopes from antigens expressed in the sporozoite and liver stage parasite, to further broaden our view of the CD8+ T cell responses induced during the pre-erythrocytic stages of malaria.

description: The problem of simultaneous rigid alignment of multiple unordered point sets which is unbiased towards any of the inputs has recently attracted increasing interest, and several reliable methods have been newly proposed. While being remarkably robust towards noise and clustered outliers, current approaches require sophisticated initialisation schemes and do not scale well to large point sets. This paper proposes a new resilient technique for simultaneous registration of multiple point sets by interpreting the latter as particle swarms rigidly moving in the mutually induced force fields. Thanks to the improved simulation with altered physical laws and acceleration of globally multiply-linked point interactions with a 2^D-tree (D is the space dimensionality), our Multi-Body Gravitational Approach (MBGA) is robust to noise and missing data while supporting more massive point sets than previous methods (with 10^5 points and more). In various experimental settings, MBGA is shown to outperform several baseline point set alignment approaches in terms of accuracy and runtime. We make our source code available for the community to facilitate the reproducibility of the results.

description: Neutrino transport and neutrino-matter interactions are known to play an important role in the evolution of neutron star mergers, and of their post-merger remnants. Neutrinos cool remnants, drive post-merger winds, and deposit energy in the low-density polar regions where relativistic jets may eventually form. Neutrinos also modify the composition of the ejected material, impacting the outcome of nucleosynthesis in merger outflows and the properties of the optical/infrared transients that they power (kilonovae). So far, merger simulations have largely relied on approximate treatments of the neutrinos (leakage, moments) that simplify the equations of radiation transport in a way that makes simulations more affordable, but also introduces unquantifiable errors in the results. To improve on these methods, we recently published a first simulation of neutron star mergers using a low-cost Monte-Carlo algorithm for neutrino radiation transport. Our transport code limits costs in optically thick regions by placing a hard ceiling on the value of the absorption opacity of the fluid, yet all approximations made within the code are designed to vanish in the limit of infinite numerical resolution. We provide here an in-depth description of this algorithm, of its implementation in the SpEC merger code, and of the expected impact of our approximations in optically thick regions. We argue that the latter is a subdominant source of error at the accuracy reached by current simulations, and for the interactions currently included in our code. We also provide tests of the most important features of this code.
