description: We predict from first-principles calculations a novel structure of stanene with dumbbell units (DB), and show that it is a two-dimensional topological insulator with inverted band gap which can be tuned by compressive strain. Furthermore, we propose that the boron nitride sheet and reconstructed ($2\times2$) InSb(111) surfaces are ideal substrates for the experimental realization of DB stanene, maintaining its non-trivial topology. Combined with standard semiconductor technologies, such as magnetic doping and electrical gating, the quantum anomalous Hall effect, Chern half metallicity and topological superconductivity can be realized in DB stanene on those substrates. These properties make the two-dimensional supported stanene a good platform for the study of new quantum spin Hall insulator as well as other exotic quantum states of matter.

description: In this paper, we consider a zero-sum undiscounted stochastic game which has finite state space and finitely many pure actions. Also, we assume the transition probability of the undiscounted stochastic game is controlled by one player and all the optimal strategies of the game are strictly positive. Under all the above assumptions, we show that the $β$-discounted stochastic games with the same payoff matrices and $β$ sufficiently close to 1 are also completely mixed. We give a counterexample to show that the converse of the above result in not true. We also show that, if we have non-zero value in some state for the undiscounted stochastic game then for $β$ sufficiently close to 1 the $β$-discounted stochastic game also possess nonzero value in the same state.

description:
The use of technology in medical sciences, specifically the use of embedded technology to correct dysfunctional organs closer to their natural state, found its place with the great cardiac surgeons from the early 1900’s like Dr. Vivien Thomas and Dr. Christiaan Barnard. The consistent leaps in the treatment of diverse, more frequent, or rare heart conditions enabled other fields of science and technology to partner and collaborate to build diverse solutions achieving long-term survival for patients of all ages.The early century pioneering of Dr. Albert S. Hyman (Harvard trained cardiologist from New York) to late century ingenuity of Dr. Jose Carlos Pachón-Mateos (University of São Paulo – USP trained cardiologist) who designed and built cardiac pacing and defibrillation devices themselves, to Biotronik SE & CO., KG and Medtronic plc, in the vanguard of researching, designing and providing state of the art pacemakers for more than fifty years, accelerating and expanding the adoption of cardiac pacemaker devices even in high-risk patients (with the incidence of various cardiovascular diseases rising across the globe.In the todays day and age, the ubiquity of pacemakers is likely to pique the interest of many who, with a quick search on the internet, will find information on websites like the great medical school Johns Hopkins University School of Medicine, popular online medical like Medicine Plus, or even Wikipedia, all of them telling us that pacemakers are devices that are surgically implanted to sustain our hearts’ electrical system.In this article, we will briefly navigate the recent history of pacemakers and respective changes in manufacturing and materials and will illustrate the incredible significance of these devices and their makers. The goal of this text is to draw the profile of the fast-paced innovations included in this famous yet misunderstood device, as well as the changes in risk and the consequences faced in the near future.

description: Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid that interacts via 5 G-protein coupled receptors, S1PR1-5, to regulate signalling pathways critical to biological processes including cell growth, immune cell trafficking, and inflammation.We demonstrate that in Type 2 diabetic (T2D) subjects, plasma S1P levels significantly increased in response to the anti-diabetic drug, rosiglitazone, and, S1P levels correlated positively with measures of improved glucose homeostasis. In HFD-induced obese C57BL/6 J mice S1PR3 gene expression was increased in adipose tissues (AT) and liver compared with low fat diet (LFD)-fed counterparts. On a HFD, weight gain was similar in both S1PR3-/- mice and WT littermates; however, HFD-fed S1PR3-/- mice exhibited a phenotype of partial lipodystrophy, exacerbated insulin resistance and glucose intolerance. This worsened metabolic phenotype of HFD-fed S1PR3-/- mice was mechanistically linked with increased adipose inflammation, adipose macrophage and T-cell accumulation, hepatic inflammation and hepatic steatosis. In 3T3-L1 preadipocytes S1P increased adipogenesis and S1P-S1PR3 signalling regulated the expression of PPARγ, suggesting a novel role for this signalling pathway in the adipogenic program. These results reveal an anti-diabetic role for S1P, and, that S1P-S1PR3 signalling in the adipose and liver defends against excessive inflammation and steatosis to maintain metabolic homeostasis at key regulatory pathways.

description: If ${\mathfrak g}$ is a real reductive Lie algebra and ${\mathfrak h} < {\mathfrak g}$ is a subalgebra, then $({\mathfrak g}, {\mathfrak h})$ is called real spherical provided that ${\mathfrak g} = {\mathfrak h} + {\mathfrak p}$ for some choice of a minimal parabolic subalgebra ${\mathfrak p} \subset {\mathfrak g}$. In this paper we classify all real spherical pairs $({\mathfrak g}, {\mathfrak h})$ where ${\mathfrak g}$ is semi-simple but not simple and ${\mathfrak h}$ is a reductive real algebraic subalgebra. The paper is based on the classification of the case where ${\mathfrak g}$ is simple (see arXiv:1609.00963) and generalizes the results of Brion and Mikityuk in the (complex) spherical case.

description: Context. Modern radio astronomical arrays have (or will have) more than one order of magnitude more receivers than classical synthesis arrays, such as the VLA and the WSRT. This makes gain calibration a computationally demanding task. Several alternating direction implicit (ADI) approaches have therefore been proposed that reduce numerical complexity for this task from $\mathcal{O}(P^3)$ to $\mathcal{O}(P^2)$, where $P$ is the number of receive paths to be calibrated. Aims. We present an ADI method, show that it converges to the optimal solution, and assess its numerical, computational and statistical performance. We also discuss its suitability for application in self-calibration and report on its successful application in LOFAR standard pipelines. Methods. Convergence is proved by rigorous mathematical analysis using a contraction mapping. Its numerical, algorithmic, and statistical performance, as well as its suitability for application in self-calibration, are assessed using simulations. Results. Our simulations confirm the $\mathcal{O}(P^2)$ complexity and excellent numerical and computational properties of the algorithm. They also confirm that the algorithm performs at or close to the Cramer-Rao bound (CRB, lower bound on the variance of estimated parameters). We find that the algorithm is suitable for application in self-calibration and discuss how it can be included. We demonstrate an order-of-magnitude speed improvement in calibration over traditional methods on actual LOFAR data. Conclusions. In this paper, we demonstrate that ADI methods are a valid and computationally more efficient alternative to traditional gain calibration method and we report on its successful application in a number of actual data reduction pipelines.

description: ΥΠΟΒΑΘΡΟ: Η έκθεση στην ηλιακή υπεριώδη (UV) ακτινοβολία είναι πιθανώς η αρχική περιβαλλοντική αιτία της πρόκλησης μελανώματος για τα δύο τρίτα αυτού του όγκου. Οι ιοί των ανθρωπίνων θηλωμάτων (HPVs) μελετώνται για να συνδεθούν πιθανώς με τους πολυάριθμους κακοήθεις όγκους του δέρματος συμπεριλαμβανομένων και των καρκινωμάτων δέρματος εκτός μελανώματος. Ο ρόλος της μόλυνσης από HPV στην ανάπτυξη μελανώματος είναι υπό διερεύνηση. ΣΤΟΧΟΙ: Ο στόχος αυτής της μελέτης ήταν να αξιολογηθούν τα δείγματα βιοψιών μελανώματος του ελληνικού πληθυσμού για την παρουσία του DNA του HPV και να καθοριστεί η πιθανή σχέση μεταξύ της μόλυνσης HPV, της κατανάλωσης τσιγάρων, της έκθεσης στον ήλιο και της κλινικής έκβασης των ασθενών πασχόντων από μελάνωμα. ΥΛΙΚΟ ΚΑΙ ΜΕΘΟΔΟΙ: Τα είκοσι εννιά δείγματα βιοψιών μελανώματος, 20 από πρωτοπαθές δερματικό μελάνωμα και 9 από μετάσταση κακοήθους μελανώματος ελήφθησαν από 29 ασθενείς. Τα δείγματα βιοψιών βρίσκονταν διατηρημένα-μονιμοποιημένα σε block παραφίνης. Η ομάδα ελέγχου αποτελείτο από τρεις συνδεσμικούς σπιλοκυτταρικούς σπίλους, που επιβεβαιώθηκαν ιστολογικά από τρεις ασθενείς και τρεις βιοψίες από φυσιολογικό δέρμα που ελήφθησαν από τρία κατά τ’άλλα υγιή άτομα. Η παρουσία και οι τύποι των DNA HPV αξιολογήθηκαν από την ενίσχυση ενός τεμαχίου της L1 περιοχής από την αλυσιδωτή αντίδραση πολυμεράσης - polymerase chain reaction (per) που συνδυάστηκε με την ανάλυση περιορισμού μήκους τεμαχίων (RFLP). Σε κάθε δείγμα βιοψιών που αξιολογήθηκε, HPV 6, HPV 11, HPV 16 και HPV 18 θετικοί μάρτυρες ελέγχου συμπεριλήφθηκαν στην per. Τα επιδημιολογικά στοιχεία των ασθενών συμπεριλαμβανομένης της κατανάλωσης τσιγάρου, του επαγγέλματος και της προηγούμενης μόλυνσης με HPV καταγράφηκαν επίσης. ΟΔΗΓΟΙ: Πέντε από 29 (17.20%) δείγματα μελανώματος βιοψιών ήταν θετικά για το DNA HPV. Αντιθέτως, HPV δεν ανιχνεύθηκε σε οποιαδήποτε από τα δείγματα βιοψιών της ομάδας ελέγχου (0/6). HPV προερχόμενος από ιό τύπος 16 βρέθηκε σε δύο δείγματα και HPV 6 DNA σε τρία. Τα αποτελέσματά μας, σχετικά με την πιθανή σχέση μεταξύ του μελανώματος και του DNA HPV, δεν ήταν στατιστικά σημαντικά (ρ>0.05). ΣΥΜΠΕΡΑΣΜΑΤΑ: Τα συμπεράσματά μας προτείνουν ότι η UV ηλιακή έκθεση παραμένει η κύρια αιτία του μελανώματος στην περιοχή μας και φαίνεται ότι το κάπνισμα συμβάλλει στη φτωχότερη έκβαση των ασθενών που πάσχουν από μελάνωμα. Ο ρόλος της δερματικής μόλυνσης HPV στην παθογένεση του μελανώματος παραμένει αόριστος.

description: Let $G$ be a connected reductive group. Previously, it was shown that for any $G$-variety $X$ one can define the dual group $G^\vee_X$ which admits a natural homomorphism with finite kernel to the Langlands dual group $G^\vee$ of $G$. Here, we prove that the dual group is functorial in the following sense: if there is a dominant $G$-morphism $X\to Y$ or an injective $G$-morphism $Y\to X$ then there is a unique homomorphism with finite kernel $G^\vee_Y\to G^\vee_X$ which is compatible with the homomorphisms to $G^\vee$.

description: A one-dimensional dielectric grating, based on a simple geometry, is proposed and investigated to enhance light absorption in a monolayer graphene exploiting guided mode resonances. Numerical findings reveal that the optimized configuration is able to absorb up to 60% of the impinging light at normal incidence for both TE and TM polarizations resulting in a theoretical enhancement factor of about 26 with respect to the monolayer graphene absorption (about 2.3%). Experimental results confirm this behaviour showing CVD graphene absorbance peaks up to about 40% over narrow bands of few nanometers. The simple and flexible design paves the way for the realization of innovative, scalable and easy-to-fabricate graphene-based optical absorbers.

description: The diffraction of fast atoms at grazing incidence on crystal surfaces (GIFAD) was first interpreted only in terms of elastic diffraction from a perfectly periodic rigid surface with atoms fixed at equilibrium position. Recently, a new approach have been proposed, referred here as the quantum binary collision model (QBCM). The QBCM takes into account both the elastic and inelastic momentum transfer via the Lamb-Dicke probability. It suggests that the shape of the inelastic diffraction profiles are log-normal distributions with a variance proportional to the nuclear energy loss deposited on the surface. For keV Neon atoms impinging the LiF surface, the predictions of the QBCM in its analytic version are compared with numerical trajectory simulations. Some of the assumptions such as the planar continuous form, the possibility to neglect the role of lithium atoms and the influence of temperature are investigated. A specific energy loss dependence $ΔE\proptoθ^7$ is identified in the quasi-elastic regime merging progressively to the classical onset $ΔE\proptoθ^3$. The ratio of these two predictions highlight the role of quantum effects in the energy loss.

description: FeSe-derived superconductors show some unique behaviors relative to iron-pnictide superconductors, which are very helpful to understand the mechanism of superconductivity in high-Tc iron-based superconductors. The low-energy electronic structure of the heavily electron-doped AxFe2Se2 (A=K, Rb, Cs) demonstrates that interband scattering or Fermi surface nesting is not a necessary ingredient for the unconventional superconductivity in iron-based superconductors. The superconducting transition temperature (Tc) in the one-unit-cell FeSe on SrTiO3 substrate can reach as high as ~65 K, largely transcending the bulk Tc of all known iron-based superconductors. However, in the case of AxFe2Se2, the inter-grown antiferromagnetic insulating phase makes it difficult to study the underlying physics. Superconductors of alkali metal ions and NH3 molecules or organic-molecules intercalated FeSe and single layer or thin film FeSe on SrTiO3 substrate are extremely air-sensitive, which prevents the further investigation of their physical properties. Therefore, it is urgent to find a stable and accessible FeSe-derived superconductor for physical property measurements so as to study the underlying mechanism of superconductivity. Here, we report the air-stable superconductor (Li0.8Fe0.2)OHFeSe with high temperature superconductivity at ~40 K synthesized by a novel hydrothermal method. The crystal structure is unambiguously determined by the combination of X-ray and neutron powder diffraction and nuclear magnetic resonance. It is also found that an antiferromagnetic order coexists with superconductivity in such new FeSe-derived superconductor. This novel synthetic route opens a new avenue for exploring other superconductors in the related systems. The combination of different structure characterization techniques helps to complementarily determine and understand the details of the complicated structures.

description: We study Landau damping in the 1+1D Vlasov-Poisson system using a Fourier-Hermite spectral representation. We describe the propagation of free energy in phase space using forwards and backwards propagating Hermite modes recently developed for gyrokinetics [Schekochihin et al. (2014)]. The change in the electric field corresponds to the net Hermite flux via a free energy evolution equation. In linear Landau damping, decay in the electric field corresponds to forward propagating Hermite modes; in nonlinear damping, the initial decay is followed by a growth phase characterised by the generation of backwards propagating Hermite modes by the nonlinear term. The free energy content of the backwards propagating modes increases exponentially until balancing that of the forward propagating modes. Thereafter there is no systematic net Hermite flux, so the electric field cannot decay and the nonlinearity effectively suppresses Landau damping. These simulations are performed using the fully-spectral 5D gyrokinetics code SpectroGK [Parker et al. 2014], modified to solve the 1+1D Vlasov-Poisson system. This captures Landau damping via an iterated Lénard-Bernstein collision operator or via Hou-Li filtering in velocity space. Therefore the code is applicable even in regimes where phase-mixing and filamentation are dominant.

description: Given a unimodular real spherical space $Z=G/H$ we construct for each boundary degeneration $Z_I=G/H_I$ of $Z$ a Bernstein morphism $B_I: L^2(Z_I)_{\rm disc }\to L^2(Z)$. We show that $B:=\bigoplus_I B_I$ provides an isospectral $G$-equivariant morphism onto $L^2(Z)$. Further, the maps $B_I$ are finite linear combinations of orthogonal projections which translates in the known cases where $Z$ is a group or a symmetric space into the familiar Maass-Selberg relations. As a corollary we obtain that $L^2(Z)_{\rm disc }\neq \emptyset$ provided that ${\mathfrak h}^\perp$ contains elliptic elements in its interior.

Examining Italian postcolonial narratives through the lens of intermediality

description: This doctoral thesis sets out to investigate how different media interact in Italian postcolonial narratives by employing the theoretical framework of intermediality. It explores how intermedial configurations create more inclusive narratives of the postcolonial identities portrayed in novels, photography series and documentaries. This central question produces two lines of enquiry; firstly, how intermediality helps to uncover layers of the Italian imperial enterprise in East Africa and its consequences on the present; and secondly, how intermediality contributes both to the field of postcolonial studies and to the understanding of the current migration experience. The thesis begins with an exploration of the theoretical intersections of intermediality and postcolonial studies, while introducing Walter Benjamin’s philosophical apparatus as a means to elucidate the conceptual overlapping between the two disciplines. A brief analysis of Cover boy. L’ultima rivoluzione (2006) showcases how intermedial investigation will be conducted in the following sections. The thesis is structured according to the three major theoretical paradigms that constitute intermediality studies which are: 1) post-structuralist philosophies used to explore the concept of in-betweenness; 2) trans-semiotic theories scrutinising media borders; 3) connections between the real and the intermedial. Each paradigm gathers a number of theoretical strands that are employed in the respective examinations conducted in the five chapters of the thesis. Building on a body of post-structuralist thought, Chapter One and Two examine how different intermedial configurations create in-betweenness in both novels Adua (2015) and Timira. Romanzo Meticcio (2012). Chapter Three scrutinises how media converge to generate Roaming (2006) and Roma negata. Percorsi postcoloniali nella città (2014) through an additional theoretical approach that borrows from the post-structuralist paradigm. Chapter Four and Chapter Five employ two different articulations of the trans-semiotic paradigm which are used in the respective examinations of the documentaries Asmarina (2015) and Pagine nascoste (2017). In the Conclusion, this study employs the third paradigm to investigate Grooving Lampedusa (2012) and reflects upon how intermedial practices encourage viewers to actively participate in the unfolding of postcolonial narratives that connect Italy’s colonial enterprise in Eastern Africa with the current migration experience in Italy.

description: We present Rossiter-McLaughlin observations of the transiting super-Earth 55 Cnc e collected during six transit events between January 2012 and November 2013 with HARPS and HARPS-N. We detect no radial-velocity signal above 35 cm/s (3-sigma) and confine the stellar v sin i to 0.2 +/- 0.5 km/s. The star appears to be a very slow rotator, producing a very low amplitude Rossiter-McLaughlin effect. Given such a low amplitude, the Rossiter-McLaughlin effect of 55 Cnc e is undetected in our data, and any spin-orbit angle of the system remains possible. We also performed Doppler tomography and reach a similar conclusion. Our results offer a glimpse of the capacity of future instrumentation to study low amplitude Rossiter-McLaughlin effects produced by super-Earths.

description: An effective way to reduce clutter in a graph drawing that has (many) crossings is to group edges that travel in parallel into \emph{bundles}. Each edge can participate in many such bundles. Any crossing in this bundled graph occurs between two bundles, i.e., as a \emph{bundled crossing}. We consider the problem of bundled crossing minimization: A graph is given and the goal is to find a bundled drawing with at most $k$ bundled crossings. We show that the problem is NP-hard when we require a simple drawing. Our main result is an FPT algorithm (in $k$) when we require a simple circular layout. These results make use of the connection between bundled crossings and graph genus.

description: Lipodystrophy is a major disturbance in people living with HIV-1 (PLWH). Several systemic alterations in PLWH are reminiscent of those that occur in ageing. It is unknown whether the lipodystrophy in PLWH is the consequence of accelerated ageing in adipose tissue. We compared systemic and adipose tissue disturbances in PLWH with those in healthy elderly individuals (~80 y old). We observed similarly enhanced expression of inflammation-related genes and decreased autophagy in adipose tissues from elderly individuals and PLWH. Indications of repressed adipogenesis and mitochondrial dysfunction were found specifically in PLWH, whereas reduced telomere length and signs of senesce were specific to elderly individuals. We conclude that ageing of adipose tissue accounts only partially for the alterations in adipose tissues of PLWH.

description: Oestrogen receptor 2 (ESR2) expression has been shown to be higher in subcutaneous adipose tissue (SAT) from postmenopausal compared to premenopausal women. The functional significance of altered ESR2 expression is not fully known. This study investigates the role of ESR2 for adipose tissue lipid and glucose metabolism. SAT biopsies were obtained from 44 female subjects with or without T2D. Gene expression of ESR2 and markers of adipose function and metabolism was assessed. ESR2 knockdown was performed using CRISPR/Cas9 in preadipocytes isolated from SAT of females, and differentiation rate, lipid storage, and glucose uptake were measured. ESR2 expression was inversely correlated with measures of central obesity and expression of some fatty acid oxidation markers, and positively correlated with lipid storage and glucose transport markers. Differentiation was reduced in ESR2 knockdown preadipocytes. This corresponded to reduced expression of markers of differentiation and lipogenesis. Glucose uptake was reduced in knockdown adipocytes. Our results indicate that ESR2 deficiency in women is associated with visceral adiposity and impaired subcutaneous adipocyte differentiation as well as glucose and lipid utilization. High ESR2 expression, as seen after menopause, could be a contributing factor to SAT expansion. This may support a possible target to promote a healthy obesity phenotype.
