description: In a recent paper Liang {\it et al.} [Nature {\bf 411}, 665 (2001)] showed experimentally, that metallic nanotubes, strongly coupled to external electrodes, may act as coherent molecular waveguides for electronic transport. The experimental results were supported by theoretical analysis based on the scattering matrix approach. In this paper we analyze theoretically this problem using a real-space approach, which makes it possible to control quality of interface contacts. Electronic structure of the nanotube is taken into account within the tight-binding model. External electrodes and the central part (sample) are assumed to be made of carbon nanotubes, while the contacts between electrodes and the sample are modeled by appropriate on-site (diagonal) and hopping (off-diagonal) parameters. Conductance is calculated by the Green function technique combined with the Landauer formalism. In the plots displaying conductance {\it vs.} bias and gate voltages, we have found typical diamond structure patterns, similar to those observed experimentally. In certain cases, however, we have found new features in the patterns, like a double-diamond sub-structure.

description: For dimensions $N \geq 4$, we consider the Brézis-Nirenberg variational problem of finding \[ S(εV) := \inf_{0\not\equiv u\in H^1_0(Ω)} \frac{\int_Ω|\nabla u|^2 \, dx +ε\int_ΩV\, |u|^2 \, dx}{\left(\int_Ω|u|^q \, dx \right)^{2/q}}, \] where $q=\frac{2N}{N-2}$ is the critical Sobolev exponent and $Ω\subset \mathbb{R}^N$ is a bounded open set. We compute the asymptotics of $S(0) - S(εV)$ to leading order as $ε\to 0+$. We give a precise description of the blow-up profile of (almost) minimizing sequences and, in particular, we characterize the concentration points as being extrema of a quotient involving the Robin function. This complements the results from our recent paper in the case $N = 3$.

description: A central question in high-dimensional mediation analysis is to infer the significance of individual mediators. The main challenge is that the total number of potential paths that go through any mediator is super-exponential in the number of mediators. Most existing mediation inference solutions either explicitly impose that the mediators are conditionally independent given the exposure, or ignore any potential directed paths among the mediators. In this article, we propose a novel hypothesis testing procedure to evaluate individual mediation effects, while taking into account potential interactions among the mediators. Our proposal thus fills a crucial gap, and greatly extends the scope of existing mediation tests. Our key idea is to construct the test statistic using the logic of Boolean matrices, which enables us to establish the proper limiting distribution under the null hypothesis. We further employ screening, data splitting, and decorrelated estimation to reduce the bias and increase the power of the test. We show that our test can control both the size and false discovery rate asymptotically, and the power of the test approaches one, while allowing the number of mediators to diverge to infinity with the sample size. We demonstrate the efficacy of the method through simulations and a neuroimaging study of Alzheimer’s disease. A Python implementation of the proposed procedure is available at https://github.com/callmespring/LOGAN.

description: Raw Data for a ManuscriptAbstract:Bacterial pathogens have evolved virulence factors to colonize, replicate, and disseminate within the vertebrate host. Although there is an expanding body of literature describing how bacterial pathogens regulate their virulence repertoire in response to diverse environmental signals, it has been challenging to directly visualize virulence response within the host tissue microenvironment. Multimodal imaging approaches enable visualization of host-pathogen interactions at the molecular level. Here we use high-resolution imaging mass spectrometry to directly visualize modifications to the Staphylococcus aureus envelope within infected murine and human tissues. Data mining strategies leveraging multimodal data-driven fusion of fluorescent bacterial reporters and MALDI FT-ICR IMS isolated S. aureus lysyl-phosphatidylglycerol lipids, localizing to select bacterial communities within infected tissue. Absence of lysyl-phosphatidylglycerol lipids is associated with decreased pathogenicity during vertebrate colonization as these lipids provide protection to S. aureus against the innate immune system. The presence of distinct and unique staphylococcal lysyl-phosphatidylglycerol lipid distributions within both murine and human infections suggests a heterogeneous, spatially-oriented microbial response to host defenses.

description: Starburst galaxies are efficient $γ$-ray producers, because their high supernova rates generate copious cosmic ray (CR) protons, and their high gas densities act as thick targets off which these protons can produce neutral pions and thence $γ$-rays. In this paper we present a first-principles calculation of the mechanisms by which CRs propagate through such environments, combining astrochemical models with analysis of turbulence in weakly ionised plasma. We show that CRs cannot scatter off the strong large-scale turbulence found in starbursts, because efficient ion-neutral damping prevents such turbulence from cascading down to the scales of CR gyroradii. Instead, CRs stream along field lines at a rate determined by the competition between streaming instability and ion-neutral damping, leading to transport via a process of field line random walk. This results in an effective diffusion coefficient that is nearly energy-independent up to CR energies of $\sim 1$ TeV. We apply our computed diffusion coefficient to a simple model of CR escape and loss, and show that the resulting $γ$-ray spectra are in good agreement with the observed spectra of the starbursts NGC 253, M82, and Arp 220. In particular, our model reproduces these galaxies' relatively hard GeV $γ$-ray spectra and softer TeV spectra without the need for any fine-tuning of advective escape times or the shape of the CR injection spectrum.

description: We present a numerical method for generating vortex rings in Bose-Einstein condensates confined in axially symmetric traps. The vortex ring is generated using the line-source approximation for the vorticity, i.e., the rotational of the superfluid velocity field is different from zero only on a circumference of given radius located on a plane perpendicular to the symmetry axis and coaxial with it. The particle density is obtained by solving a modified Gross-Pitaevskii equation that incorporates the effect of the velocity field. We discuss the appearance of density profiles, the vortex core structure and the vortex nucleation energy, i.e., the energy difference between vortical and ground-state configurations. This is used to present a qualitative description of the vortex dynamics.

description: Stellar clusters are born embedded within giant molecular clouds (GMCs) and during their formation and early evolution are often only visible at infrared wavelengths, being heavily obscured by dust. Over the last 15 years advances in infrared detection capabilities have enabled the first systematic studies of embedded clusters in galactic molecular clouds. In this article we review the current state of empirical knowledge concerning these extremely young protocluster systems. From a survey of the literature we compile the first extensive catalog of galactic embedded cluster properties. We use the catalog to construct the mass function and estimate the birthrate for embedded clusters within roughly 2 Kpc of the Sun. We find that the embedded cluster birthrate exceeds that of visible open clusters by an order of magnitude or more indicating a high infant mortality rate for protocluster systems. Less than 4-7% of embedded clusters survive emergence from molecular clouds to become bound clusters of Pleiades age. The vast majority (90%) of stars that form in embedded clusters form in rich clusters of 100 or more members with masses in excess of 50 solar masses. We review the role of embedded clusters in investigating the nature of the IMF which, in one nearby example, has been measured over the entire range of stellar and substellar mass, from OB stars to subsellar objects near the deuterium burning limit. We also review the role embedded clusters play in the investigation of circumstellar disk evolution and the important constraints they provide for understanding the origin of planetary systems. Finally, we discuss current ideas concerning the origin and dynamical evolution of embedded clusters and the implications for the formation of bound open clusters.

description: We perform numerical studies of the wave packet propagation through open quantum billiards whose classical counterparts exhibit regular and chaotic dynamics. We show that for t less or similar to tau (tau being the Heisenberg time), the features in the transmitted and reflected currents are directly related to specific classical trajectories connecting the billiard leads. In contrast, the long-time asymptotics of the wave packet dynamics is qualitatively different for classical and quantum billiards. In particularly, the decay of the quantum system obeys a power law that depends on the number of decay channels, and is not sensitive to the nature of classical dynamics (chaotic or regular).

description: We study neighborhoods of configurations of symplectic surfaces in symplectic 4-manifolds. We show that suitably `positive' configurations have neighborhoods with concave boundaries and we explicitly describe open book decompositions of the boundaries supporting the associated negative contact structures. This is used to prove symplectic nonfillability for certain contact 3-manifolds and thus nonpositivity for certain mapping classes on surfaces with boundary. Similarly, we show that certain pairs of contact 3-manifolds cannot appear as the disconnected convex boundary of any connected symplectic 4-manifold. Our result also has the potential to produce obstructions to embedding specific symplectic configurations in closed symplectic 4-manifolds and to generate new symplectic surgeries. From a purely topological perspective, the techniques in this paper show how to construct a natural open book decomposition on the boundary of any plumbed 4-manifold. Erratum (added December 2003): We correct the main theorem and its proof. As originally stated, the theorem gave conditions on a configuration of symplectic surfaces in a symplectic 4-manifold under which we could construct a model neighborhood with concave boundary and describe explicitly the open book supporting the contact structure on the boundary. The statement should have included constraints on the areas of the surfaces.

description: We study M-theory compactification on ${\mathbb{T}^7/ \mathbb{Z}_2^3}$ in the presence of a seven-flux, metric fluxes and KK monopoles. The effective four-dimensional supergravity has seven chiral multiplets whose couplings are specified by the $G_2$-structure of the internal manifold. We supplement the corresponding superpotential by a KKLT type non-perturbative exponential contribution for all, or for some of the seven moduli, and find a discrete set of supersymmetric Minkowski minima. We also study type IIA and type IIB string theory compactified on ${\mathbb{T}^6/ \mathbb{Z}_2^2}$. In type IIA, we use a six-flux, geometric fluxes and non-perturbative exponents. In type IIB theory, we use F and H fluxes, and non-geometric Q and P fluxes, corresponding to consistently gauged supergravity with certain embedding tensor components, \emph{without non-perturbative exponents}. Also in these situations, we produce discrete Minkowski minima. Finally, to construct dS vacua starting from these Minkowski progenitors, we follow the procedure of mass production of dS vacua.

description: In recent years, there has been a marked increase in the creation of alternative family structures by same-sex individuals and same-sex couples through various means. These families deviate from traditional models and include a variety of settings. Despite increasing diversity, the legal recognition and rights of same-sex couples as parents varies widely in different regions, with some regions offering full legal rights while others present significant legal barriers and discrimination. Social attitudes towards same-sex parenthood also vary, affecting the well-being of both parents and children. The purpose of this research is to provide comprehensive information on non-traditional family structures formed by same-sex individuals and same-sex couples. It seeks to educate readers about the different methods of family formation, issues of legal recognition, social attitudes and research findings on the upbringing of children, especially during the preschool age, who grow up in such families. Overall previous research consistently shows that children raised by same-sex parents do just as well as those raised by heterosexual parents, with the quality of the family environment being the critical factor in children's emotional, social and academic development. The paper begins with an exploration of fundamental concepts in the field of sexuality and gender identity. Chapter 1 delves into key definitions, including an examination of homosexuality and gay identity development, as well as an overview of the LGBTQI community and the dynamics of same-sex parenting. Moving on to Chapter 2, the focus shifts to the legislative landscapes and social attitudes concerning LGBTQI people, both globally and specifically in Greece. Chapter 3 then delves into the complexities of parenting by same-sex couples, detailing the different types of LGBTQI couples as parents, the unique challenges they face, and an analysis of research on developmental outcomes and parenting in preschool. in these families. Through this comprehensive exploration, the paper aims to provide a nuanced understanding of the experiences and realities of same-sex couples in the context of parenting.

description: We describe a population of young star clusters (SCs) formed in a hydrodynamical simulation of a gas-rich dwarf galaxy merger resolved with individual massive stars at sub-parsec spatial resolution. The simulation is part of the GRIFFIN (Galaxy Realizations Including Feedback From INdividual massive stars) project. The star formation environment during the simulation spans seven orders of magnitude in gas surface density and thermal pressure, and the global star formation rate surface density ($Σ_\mathrm{SFR}$) varies by more than three orders of magnitude during the simulation. Young SCs more massive than $M_{\mathrm{*,cl}}\sim 10^{2.5}\,M_{\odot}$ form along a mass function with a power-law index $α\sim-1.7$ ($α\sim-2$ for $M_{\mathrm{*,cl}}\gtrsim10^{3}\,M_{\odot}$) at all merger phases, while the normalization and the highest SC masses (up to $\sim 10^6 M_{\odot}$) correlate with $Σ_\mathrm{SFR}$. The cluster formation efficiency varies from $Γ\sim20\%$ in early merger phases to $Γ\sim80\%$ at the peak of the starburst and is compared to observations and model predictions. The massive SCs ($\gtrsim10^4\,M_{\odot}$) have sizes and mean surface densities similar to observed young massive SCs. Simulated lower mass clusters appear slightly more concentrated than observed. All SCs form on timescales of a few Myr and lose their gas rapidly resulting in typical stellar age spreads between $σ\sim0.1-2$ Myr ($1σ$), consistent with observations. The age spreads increase with cluster mass, with the most massive cluster ($\sim10^6\, M_{\odot}$) reaching a spread of $5\, \mathrm{Myr}$ once its hierarchical formation finishes. Our study shows that it is now feasible to investigate the SC population of entire galaxies with novel high-resolution numerical simulations.

description: Understanding the process and the dynamics involved in news translation, as well as the challenges news translators face in my country of origin - The Gambia- has been a long-held goal, considering my background and experience as a former bilingual editor for Kuwait Oil Company and a senior news translator for Al-Watan Daily in Kuwait. The quest to unravel the enigmas surrounding news translation practices has always been a subject of great interest to me. With the intent of proffering pragmatic solutions to the attendant challenges of news translation in the Gambia, my focus is on providing well-researched recommendations. The study specifically seeks to answer questions regarding news translation processes and practices and how they have evolved over time in the Gambia. Furthermore, this study sheds light on the manifold professional and technical obstacles that confront news translators in the Gambia as they endeavour to render news content originally produced in English into Mandinka, which is one of the prominent Indigenous languages. It also delves into the broader linguistic landscape in the Gambia and other colonized territories from an indigenous perspective. Colonialism looms large over my study, considering the fact that news is translated from English, a minority colonial language imposed on the majority speakers of indigenous languages. The legacy of colonialism still lingers, with the news still being read in English first before it gets rendered in indigenous languages. Using qualitative methodology, my research explores the evolution and importance of news translation in the Gambia and the underlying factors behind the professional and technical challenges that Gambia’s news translators continue to wrestle with. Dowling, Lloyd, and Suchet-Pearson (2016) posit that this methodology is employed to comprehend the spatialities, interpretations, and experiences of social life. The undertaken field study has availed me of the opportunity to have a deeper understanding of some of those challenges and come up with recommendations that might hopefully address them, including language planning, the development of a monolingual Mandinka dictionary, translator training, the development of unique Mandinka writing systems, among others. My research participants were enthused to participate in the study, affirming that it was the first time ever a researcher approached them to have an idea about the dynamics of their work and include their findings in a thesis—an assertion that sustained the momentum throughout the journey.

description: We present a new approach in modelling the polarized Galactic synchrotron emission in the microwave range (20-100 GHz), where this radiation is expected to play the leading role in contaminating the Cosmic Microwave Background (CMB) data. Our method is based on real surveys and aims at providing the real spatial distributions of both polarized intensity and polarization angles. Its main features are the modelling of a polarization horizon to determine the polarized intensity and the use of starlight optical data to model the polarization angle pattern. Our results are consistent with several existing data, and our template is virtually free from Faraday rotation effects as required at frequencies in the cosmological window.

description: We attack generalized Thomson problems with a continuum formalism which exploits a universal long range interaction between defects depending on the Young modulus of the underlying lattice. Our predictions for the ground state energy agree with simulations of long range power law interactions of the form 1/r^{gamma} (0 < gamma < 2) to four significant digits. The regime of grain boundaries is studied in the context of tilted crystalline order and the generality of our approach is illustrated with new results for square tilings on the sphere.

Self-Care in Young People With Diabetes: A Qualitative Exploration Using a Salutogenic Approach
Creators: name: Green, Emma
Publisher: name: University of East London
Year: 2018

description: This thesis investigates experiences of self-care amongst young people with diabetes using a qualitative salutogenic approach. Diabetes self-care includes injecting insulin, counting carbohydrates, attending hospital check-ups and other activities to maintain stable blood sugar levels. Optimal blood sugar levels are not always easy for young people with diabetes to attain, placing them at increased risk of health complications. A lack of self-care has been assumed traditionally to indicate a lack of knowledge. This exemplifies a ‘deficit’ approach whereby efforts to improve self-care focus heavily on diabetes education to increase knowledge. However, there is a lack of evidence that young people lack diabetes knowledge or that education-only interventions are effective. This thesis applies salutogenesis as an alternative to the deficit approach in which young people are conceptualised as individuals and their capabilities are acknowledged. The empirical work undertaken includes: a meta-ethnography of the international qualitative literature, analysis of semi-structured interviews with young people living in a diverse urban area of the UK, defined as disengaged from diabetes self-care (N=14): and a qualitative study conducted with young people participating in novel salutogenic projects which focused on their capabilities rather than ‘correcting’ their deficits (N=5). Across the studies it was found that ‘identity work’ underpins young people’s experiences with diabetes self-care. Identity work is the continual negotiation of diabetes into self-concept (‘being’ identity) and diabetes self-care into daily life (‘doing’ identity). This involves navigating threats to and validators of identity within the home, the diabetes clinic, the school and the social environment, to achieve a sense of normality. Identity work is fluid and comprises three types: ‘forgetting diabetes’, ‘diabetes as dominating’ and ‘diabetes as routine’, each of which are associated with different levels of engagement with diabetes self-care. Participating in salutogenic projects enabled young people to better navigate identity work and thus integrate diabetes into both ‘being’ and ‘doing’ identity. This thesis demonstrates that diabetes self-care is a manifestation of young people’s ongoing identity work and that this identity work is modifiable. Further research should explore the way in which salutogenic projects can enhance engagement with diabetes self-care on a larger scale.

description: We present new BV CCD photometry, light curves, and ephemerides for 9 previously known, 29 newly detected RR Lyrae variables and one newly detected variable of an unknown type in the globular cluster M75. The photometry used for the detection of the additional variables was obtained with the image subtraction package ISIS. The data were acquired on an observing run in July 1999 and range over 7 observing nights. Estimates of fundamental photometric parameters are presented including intensity- and magnitude-averaged B and V magnitudes, magnitude-averaged colors, pulsation periods, and pulsation amplitudes. The mean period of the RRab variables, = 0.5868 d, and the number fraction of RRc stars, N_c/N_RR = 0.342, are both large for an Oosterhoff type I (OoI) globular cluster, suggesting that M75 may be Oosterhoff-intermediate. Possible conflicts between Oosterhoff-type determination based on the A_V - logP and A_B - logP diagrams are discussed. The physical parameters of the RRc and RRab variables, as obtained from Fourier decomposition of their light curves, do not show any clear deviation from normal OoI behavior.

Surprises in the simultaneous X-ray and optical monitoring of pi Aqr

description: To help constrain the origin of the peculiar X-ray emission of gamma Cas stars, we conducted a simultaneous optical and X-ray monitoring of pi Aqr in 2018. At that time, the star appeared optically bright and active, with a very strong Halpha emission. Our monitoring covers three 84d orbital cycles, allowing us to probe phase-locked variations as well as longer-term changes. In the new optical data, the radial velocity variations seem to span a smaller range than previously reported, which might indicate possible biases. The X-ray emission is variable, but without any obvious correlation with orbital phase or Halpha line strength. Furthermore, the average X-ray flux and the relative range of flux variations are similar to those recorded in previous data, although the latter data were taken when the star was less bright and its disk had nearly entirely disappeared. Only the local absorption component in the X-ray spectrum appears to have strengthened in the new data. This absence of large changes in X-ray properties despite dramatic disk changes appears at odds with previous observations of other gamma Cas stars. It also constrains scenarios proposed to explain the gamma Cas phenomenon.

description: Η εργασία εξετάζει την επίδραση της χρήσης των αεροτομών στο μπροστινό spoiler μηχανής ώστε να βελτιωθεί η πρόσφυση . Αρχικά ,γίνεται μια εισαγωγή στον ορισμό της αεροτομής και στα γεωμετρικά χαρακτηριστικά της. Οι κύριες δυνάμεις που μας ενδιαφέρουν στις αεροτομές είναι οι ανοδικές-καθοδικές και η οπισθέλκουσα. Οι συντελεστές αυτών των δυνάμεων επηρεάζονται από διάφορους παράγοντες όπως παρουσιάζονται με διαγράμματα στην εργασία. Οι αεροτομές χρησιμοποιούνται πχ( σε αεροπλάνα για άνωση ,σε ανεμογεννήτριες για την παραγωγή ηλεκτρισμού) κλπ. όμως στις μηχανές αγώνων είναι σε πρώιμο στάδιο πραγμα που εξετάζεται στην εργασία. Οπότε επιλέχθηκαν 3 είδη αεροτομών προς εξέταση. Οι NACA 6412 ,NACA 23015, NASA SC(2)0714. Παρατίθενται τα χαρακτηριστικά τους. Στη συνέχεια δημιουργείται στο CAD solidworks το spoiler με την ρόδα με βάσει σχέδια των διατάσεων μηχανής και του ελαστικού της ρόδας που βρέθηκαν στο ίντερνετ. Έπειτα ,έγινε ανάλυση των δυνάμεων που ασκούνται στις αεροτομές μέσω προγράμματος υπολογιστικής ρευστοδυναμικής του solidworks. Εκεί παρουσιάζονται οι πιέσεις και οι ταχύτητες του αέρα πάνω στην επιφάνεια των αεροτομών και υπολογίζονται η τελική κάθετη και οπισθέλκουσα δύναμη για κάθε αερoτομή μεμονωμένα. Συγκρίνονται τα αποτελέσματα και την χαμηλότερη καθοδική δύναμη έχει η NACA 23015 άρα απορρίπτεται. Στη συνέχεια γίνεται ανάλυση δυνάμεων του συστήματος spoiler –ρόδα με τις άλλες δύο αεροτομές (NACA 6412 και NASA SC(2)-0714) και βρίσκεται ότι έχουμε δυνάμεις άνωσης. Το σύστημα spoiler-ρόδα NACA 6412 έχει την μικρότερη άνωση άρα επιλέγεται αυτή ως βέλτιστη. Παρόλα αυτά ,το ζητούμενο είναι η καθοδική δύναμη άρα με βάσει διάφορες αλλαγές στην πχ (γωνία προσβολής, χρήση δεύτερης αεροτομής κλπ.) έχουμε σαν αποτέλεσμα μια βελτιωμένη εκδοχή της NACA 6412. Τέλος ,παρουσιάζονται οι δυνατότητες της χρήσης αεροτομών και για μελλοντικές μελέτες ώστε να αναπτυχθεί παραπάνω η αεροδυναμική των αγωνιστικών μηχανών.
