Tra Grecia e Oriente: geografie identitarie dell'immaginario russo nel periodo simbolista
Creators: name: MORABITO, MARTINA
Publisher: name: Universit� degli studi di Genova
Year: 2020

description: L?idea centrale della presente indagine � che il periodo simbolista russo abbia riformulato la propria identit� culturale in termini simbolici di trasferimento dell?identit� spaziale, plasmando e utilizzando in chiave identitaria un luogo immaginario, una ?regione psichica? formata da una sovrapposizione di mondo greco classico e Oriente. Lo studio rientra nell?ambito delle riconsiderazioni da un punto di vista spaziale dei fenomeni del modernismo occidentale, avendo come obiettivo l?inserimento del fenomeno simbolista russo all?interno del pi� vasto modernismo europeo. L?indagine affianca lo studio di testi letterari e teorici e dell?arte visuale all?analisi di mappe geografiche; queste ultime sono presentate in due accezioni differenti, essendo, a seconda dei casi, oggetto di indagine o strumento critico elaborato a posteriori. Per delineare un contesto pi� ampio, oltre alle opere del canone simbolista, sono inclusi nello studio testi non strettamente riconducibili al movimento stesso, ma attinenti al relativo periodo storico: discorsi dell?ideologia dominante e imperiale, scritti odeporici da posizioni marginali e minoritarie, studi geografici di anarchici e scienziati.

description: We present a new way of describing the flares from Sgr A* with a self-consistent calculation of the particle distribution. All relevant radiative processes are taken into account in the evolution of the electron distribution and resulting spectrum. We present spectral modelling for new X-ray flares observed by NuSTAR, together with older observations in different wavelengths, and discuss the changes in plasma parameters to produce a flare. We show that under certain conditions, the real particle distribution can differ significantly from standard distributions assumed in most studies. We conclude that the flares are likely generated by magnetized plasma consistent with our understanding of the accretion flow. Including non-thermal acceleration, injection, escape, and cooling losses produces a spectrum with a break between the infrared and the X-ray, allowing a better simultaneous description of the different wavelengths. We favour the non-thermal synchrotron interpretation, assuming the infrared flare spectrum used is representative. We also consider the effects on Sgr A*s quiescent spectrum in the case of a density increase due to the G2 encounter with Sgr A*.

Extensions and Experimental Evaluation of SAT-based solvers for the UAQ problem

Publisher: name: Universit� degli studi di Genova
Year: 2020

description: Nowadays, most of the health organizations make use of Health Information Systems (HIS) to support the staff to provide patients with proper care service. In this context, security and privacy are key to establish trust between the actors involved in the healthcare process, including the patient. However, patients' privacy cannot jeopardize their safety: as a consequence, a compromise between the two must eventually be found. Privilege management and access control are necessary elements to provide security and privacy. In this thesis, we first present the main features that make the Role Based Access Control suitable for permissions management and access control in HIS. We then address the User Authorization Query (UAQ) problem for RBAC, namely the problem of determining the optimum set of roles to activate to provide the user with the requested permissions (if the user is authorized) while satisfying a set of Dynamic Mutually Exclusive Roles (DMER) constraints and achieving some optimization objective (least privilege versus availability). As a first contribution, we show how DMER can be used to support the enforcement of SoD. The UAQ problem is known to be NP-hard. Most of the techniques proposed in the literature to solve it have been experimentally evaluated by running them against different benchmark problems. However, the adequacy of the latter is seldom discussed. In this thesis, we propose a methodology for evaluating existing benchmarks or designing new ones: the methodology leverages the asymptotic complexity analysis of the solving procedures provided in other works to forsee the benchmarks complexity given the values of the most significant RBAC dimensions. First, we use our methodology to demonstrate that the state-of-the-art benchmarks are unsatisfactory. We then introduce UAQ-Solve, a tool that works both as generator of benchmarks and as UAQ solver leveraging existing PMAXSAT complete solvers. By using UAQ-Solve, we apply our methodology to generate a novel suite of parametric benchmarks that allows for the systematic assessment of UAQ solvers over a number of relevant dimensions. These include problems for which no polynomial-time algorithm is known as well as problems for which polynomial-time algorithms do exist. We then execute UAQ-Solve over our benchmarks to compare the performance of different complete and incomplete PMAXSAT solvers.

description: The inviscid Burgers equation is one of the simplest nonlinear hyperbolic conservation law which provides a variety examples for many topics in nonlinear partial differential equations such as wave propagation, shocks and perturbation, and it can easily be derived by the Euler equations of compressible fluids by imposing zero pressure in the given system. Recently, several versions of the relativistic Burgers equations have been derived on different geometries such as Minkowski (flat), Schwarzshild and FLRW spacetimes by LeFloch and his collaborators. In this paper, we consider a family member of the FLRW spacetime so-called the de Sitter background, introduce some important features of this spacetime geometry with its metric and derive the relativistic Burgers equation on it. The Euler system of equations on the de Sitter spacetime can be found by a known process by using the Christoffel symbols and tensors for perfect fluids. We applied the usual techniques used for the Schwarzshild and FLRW spacetimes in order to derive the relativistic Burgers equation from the vanishing pressure Euler system on the de Sitter background. We observed that the model admits static solutions. In the final part, we examined several numerical illustrations of the given model through a finite volume approximation based on the paper by LeFloch et al. The effect of the cosmological constant is also numerically analysed in this part. Furthermore, a comparison of the static solution with the Lax Friedrichs scheme is implemented so that the results demonstrate the efficiency and robustness of the finite volume scheme for the derived model

Epigenetic mechanisms for nutrition determinants of later health outcomes
Creators: name: Zeisel, Steven H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Epigenetic marking on genes can determine whether or not genes are expressed. Epigenetic regulation is mediated by the addition of methyl groups to DNA cytosine bases, of methyl and acetyl groups to proteins (histones) around which DNA is wrapped, and by small interfering RNA molecules. Some components of epigenetic regulation have evolved to permit control of whether maternal or paternal genes are expressed. The epigenetic imprinting of IGF2 expression is an example of maternal and paternal epigenetic marking that modulates fetal growth and fetal size. However, epigenetic regulation also permits the fetus and the infant to adapt gene expression to the environment in which it is growing; sometimes when this adjustment goes awry, the risk of chronic disease is increased. Recent progress in the understanding of nutritional influences on epigenetics suggests that nutrients that are part of methyl-group metabolism can significantly influence epigenetics. During critical periods in development, dietary methyl-group intake (choline, methionine, and folate) can alter DNA and histone methylation, which results in lifelong changes in gene expression. In rodent models, pregnant dams that were fed diets high in methionine, folic acid, and choline produced offspring with different coat colors or with kinked tails. A number of syndromes in humans can be caused by defective epigenetic regulation, including Rett syndrome. There are interesting examples of the effects of nutrition in early life that result in altered health in adults, and some of these could be the result of altered epigenetic regulation of gene expression.

Biological and transcriptional regulation of the culprit in PDX lymphoma model

Year: 2020

description: The anaplastic large cell lymphoma (ALCL), a subtype of peripheral T-cell lymphoma (PTCL), is a lymphoid malignancy characterized by a ?hallmark cells? and elevated expression of CD30. Anaplastic lymphoma kinase?positive (ALK+) carry ALK fusions, more often the NPM-ALK t(2;5) translocation, while about 40% of all ALCLs are negative (ALK-). ALK chimeras promote cell survival and tumorigenesis by constitutively activating multiple cell signaling pathways, including the STAT3 pathway. STAT3 is a member of family Signal Transducers and Activators of Transcription (STATs), and its chronic activation has been proven to play a role in the pathogenesis of several PTCL malignancies. Remarkably, approximately 50% of all ALK- ALCL have been proven to display the deregulated activation of the JAK-STAT3 pathway which is required for the maintenance of their neoplastic phenotype. Here we described a series of pharmacological approaches designed to modulate the activity of STAT3 signaling. To achieve this objective, we have focused on ALK+ and ALK- ALCL cell lines and PDX models. We have taken advantage of two different but complementary molecules: a selective STAT3 binding compound named JPX-XX1, and two specific STAT3 degraders (A1 and N1). Both JPX-XX1 and A1 and N1 compounds were proven to reduce the cell growth and metabolic activity of ALK+ as well as selected ALK- ALCL cell lines, in a dose-dependent manner. As predicted both degraders were efficiently and selectively capable to degrade STAT3, a phenotype that was maintained over time (6 days of treatment) after a single dose exposure. Mechanistically, the loss of STAT3 was associated with a cell cycle arrest and increased apoptosis. Collectively our data by confirming previous findings further demonstrate the pivotal role of STAT3 signaling in ALCL. More importantly, these compounds open new and feasible therapeutic avenues for the treatment of ALCL. A strategy that may be successfully applied to other JAK/STAT3 dependent lymphoproliferative disorders.

description: Refined constraints on chameleon theories are calculated for atom-interferometry experiments, using a numerical approach consisting in solving for a four-region model the static and spherically symmetric Klein-Gordon equation for the chameleon field. By modeling not only the test mass and the vacuum chamber but also its walls and the exterior environment, the method allows to probe new effects on the scalar field profile and the induced acceleration of atoms. In the case of a weakly perturbing test mass, the effect of the wall is to enhance the field profile and to lower the acceleration inside the chamber by up to one order of magnitude. In the thin-shell regime, results are found to be in good agreement with the analytical estimations, when measurements are realized in the immediate vicinity of the test mass. Close to the vacuum chamber wall, the acceleration becomes negative and potentially measurable. This prediction could be used to discriminate between fifth-force effects and systematic experimental uncertainties, by doing the experiment at several key positions inside the vacuum chamber. For the chameleon potential $V(ϕ) = Λ^{4+α} / ϕ^α$ and a coupling function $A(ϕ) = \exp(ϕ/M)$, one finds $M \gtrsim 7 \times 10^{16} \mathrm{GeV}$, independently of the power-law index. For $V(ϕ) = Λ^4 (1+ Λ/ ϕ)$, one finds $M \gtrsim 10^{14} \mathrm{GeV}$. A sensitivity of $a\sim 10^{-11} \mathrm{m/s^2} $ would probe the model up to the Planck scale. Finally, a proposal for a second experimental set-up, in a vacuum room, is presented. In this case, Planckian values of $M$ could be probed provided that $a \sim 10^{-10} \mathrm{m/s^2}$, a limit reachable by future experiments. Our method can easily be extended to constrain other models with a screening mechanism, such as symmetron, dilaton and f(R) theories.

description: We derive a factorization theorem for the Higgs-boson production amplitude in gluon-gluon fusion induced by a light-quark loop, working at next-to-leading power in soft-collinear effective theory. The factorization is structurally similar to that obtained for the $h\toγγ$ decay amplitude induced by a light-quark loop, but additional complications arise because of external color charges. We show how the refactorization-based subtraction scheme developed in previous work leads to a factorization theorem free of endpoint divergences. We use renormalization-group techniques to predict the logarithmically enhanced terms in the three-loop $gg\to h$ form factor of order $α_s^3\ln^k(-M_h^2/m_b^2)$ with $k=6,5,4,3$. We also resum the first three towers of leading logarithms, $α_s^n\ln^{2n-k}(-M_h^2/m_b^2)$ with $k=0,1,2$, to all orders of perturbation theory.

description: Il principale oggetto di studio della tesi � il percorso di elaborazione politica compiuto dai fondatori de Il Manifesto. Nata nel corso della straordinaria stagione del 1968-69, la rivista si distingue nel contesto delle nuove sinistre europee per il tentativo di offrire una risposta globale al dissenso comunista attraverso un pensiero organizzato, volto a diventare una piattaforma teorica per l?aggregazione ?della sinistra di classe?. Un?evidente lacuna a livello storiografico ha impedito, sino a oggi, di approfondire in maniera sistematica il pensiero politico de Il Manifesto, riflettendo in maniera critica sul percorso che, a partire dal dibattito sul centro-sinistra, ha condotto il nucleo di fondatori attraverso lo sviluppo di una componente di sinistra all?interno del Partito Comunista Italiano, fino alla teorizzazione di un comunismo non ortodosso. La tesi mette in luce i pi� significativi nodi interpretativi emersi dalla ricostruzione di ?lungo? periodo, a partire dal dibattito apertosi nella sinistra marxista nel 1956 fino alla fondazione della rivista nel giugno del 1969: dal ruolo di primo piano di Aldo Natoli e Rossana Rossanda in termini di apporto culturale e politico alla definizione della piattaforma progettuale proposta dalla rivista, la maturazione del dissenso nei confronti del Partito Comunista Italiano, la costruzione di un?alternativa al marxismo classico, il processo di formazione di una componente di sinistra all?interno del partito, la fondazione della rivista. L?analisi delle Tesi per il comunismo, ?una piattaforma di discussione e di lavoro politico per l?unit� della sinistra rivoluzionaria e la costruzione di una nuova forza politica? pone in evidenza gli aspetti pi� originali del percorso di elaborazione teorica collettiva compiuto dal gruppo dissidente, in cui confluiscono numerose e diverse matrici ideali e filosofiche: si tratta di rinnovamento del marxismo italiano che distingue la storia de Il Manifesto da quella delle altre formazioni rivoluzionarie nate dopo il 1968, una galassia spesso presentata dalla storiografia come indistinta.

description: We define a canonical ensemble for a gravitational causal diamond by introducing an artificial York boundary inside the diamond with a fixed induced metric and temperature, and evaluate the partition function using a saddle point approximation. For Einstein gravity with zero cosmological constant there is no exact saddle with a horizon, however the portion of the Euclidean diamond enclosed by the boundary arises as an approximate saddle in the high-temperature regime, in which the saddle horizon approaches the boundary. This high-temperature partition function provides a statistical interpretation of the recent calculation of Banks, Draper and Farkas, in which the entropy of causal diamonds is recovered from a boundary term in the on-shell Euclidean action. In contrast, with a positive cosmological constant, as well as in Jackiw-Teitelboim gravity with or without a cosmological constant, an exact saddle exists with a finite boundary temperature, but in these cases the causal diamond is determined by the saddle rather than being selected a priori.

description: We study the dynamics of condensation in a misanthrope process with nonlinear jump rates and factorized stationary states. For large enough density, it is known that such models have a phase separated state, with a non-zero fraction of the total mass concentrating in a single lattice site. It has been established in [B Waclaw and M R Evans, Phys. Rev. Lett., 108(7):070601, 2012] for asymmetric dynamics that such processes exhibit explosive condensation, where the time to reach the stationary state vanishes with increasing system size. This constitutes a spatially extended version of instantaneous gelation which has previously been studied only in mean-field coagulation models. We show that this phenomenon also occurs for symmetric dynamics in one dimension if the non-linearity is strong enough, and we find a coarsening regime where the time to stationarity diverges with the system size for weak non-linearity. In higher space dimensions explosive condensation is expected to be generic for all parameter values. Our results are based on heuristic mean field arguments which are confirmed by simulation data.

Importance of methyl donors during reproduction 1-4
Creators: name: Zeisel, Steven H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: Evidence is growing that optimal dietary intake of folate and choline (both involved in one-carbon transfer or methylation) is important for successful completion of fetal development. Significant portions of the population are eating diets low in one or both of these nutrients. Folates are important for normal neural tube closure in early gestation, and the efficacy of diet fortification with folic acid in reducing the incidence of neural tube defects is a major success story for public health nutrition. Similarly, maternal dietary choline is important for normal neural tube closure in the fetus and, later in gestation, for neurogenesis in the fetal hippocampus, with effects on memory that persist in adult offspring; higher choline intake is associated with enhanced memory performance. Although both folates and choline have many potentially independent mechanisms whereby they could influence fetal development, these 2 nutrients also have a common mechanism for action: altered methylation and related epigenetic effects on gene expression.

description: Quantum sensing improves the accuracy of measurements of relevant parameters by exploiting the unique properties of quantum systems. The divergent susceptibility of physical systems near a critical point for quantum phase transition enables criticality-enhanced quantum sensing. The quantum Rabi model (QRM), composed of a single qubit coupled to a single bosonic field, represents a good candidate for realizing such critical enhancement for its simplicity, but it is experimentally challenging to achieve the ultrastrong qubit-field coupling required to realize the critical phenomena. In this work, we explore an alternative to construct the analog of the QRM for the sensing, exploiting the criticality appearing in the Jaynes-Cummings (JC) model whose bosonic field is parametrically driven, not necessitating the ultrastrong coupling condition thus to some extent relaxing the requirement for the practical implementation.

Is maternal diet supplementation beneficial? Optimal development of infant depends on mother’s diet
Creators: name: Zeisel, Steven H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: There are periods during perinatal development in which specific nutrients are required for optimal development, and there is growing evidence that optimal dietary intake of these nutrients, which include iodine, docosahexaenoic acid, choline, and folate, is important. Lessons in how these nutrient effects were identified can help us to broaden our approaches for finding other critical nutrients: we are looking for nutrients for which there is a wide range of dietary intake, that have no or marginal pathways for biosynthesis, and that are needed by dividing progenitor cells. For some of the nutrients discussed, such as iodine and folate, the effects in humans are abundantly clear; for others, animal data are the most convincing. More human studies need to be conducted. We need a better understanding of diet and diet supplement intake during pregnancy and lactation and of whether diets are particularly low in some nutrients. Also, we need to understand how common genetic variations influence nutrient requirements during these periods. If we are going to supplement maternal and infant diets, first we must understand much more about the risks of having too much of a critical nutrient. Whatever the limitations of our current state of knowledge, it is apparent that pregnancy and lactation are periods during which good nutrition is exceptionally important. The infant is not protected from the inadequate diet of the mother.
Supersymmetry discovery potential in the 2 leptons channel with ATLAS
Creators: name: DE SANCTIS, UMBERTO
Publisher: name: Universit� degli Studi di Milano
Year: 2009

description: The main argument of the PhD thesis is the evaluation of the ATLAS detector potential to discover Supersymmetry and to estimate the masses of the supersymmetric particles produced in events with two isolated leptons (electrons or muons) in the final state. The Supersymmetry (SUSY) is one of the most credited theories to extend the Standard Model (SM). This theory foresees a new class of particles that can be detected reconstructing their decay chains. Under some basic assumptions that define the mSUGRA model, all these chains finish with the Lightest SUSY Particle (LSP) that is stable, neutral and weakly interacting: a good candidate for the Cold Dark Matter. The LSP escapes the detection originating a large amount of missing energy in the detector. Within the mSUGRA model, this channel is then characterised by the presence of two isolated leptons, missing energy and energetic jets. A strategy to estimate the SM background in this channel using only real data has been developed allowing the discovery of SUSY already with 1 fb-1 of data collected if the mass of squarks and gluino is about 400 GeV/c2. A technique to extract some information on the SUSY mass particles spectrum using the two reconstructed leptons has also been developed, reconstructing the decay of SUSY particles in order to point out the characteristic edge in the di-lepton invariant mass distribution that allows to extract information about the masses of the SUSY particles involved in the decay chain.

description: We study the distribution of arithmetic invariants associated to Alexander polynomials for certain infinite families of links. The families of links we consider arise from braids on a fixed number of strings. We explore analogies with number theory and the distribution of class groups in various families of number fields, setting out new directions in arithmetic topology and arithmetic statistics.

description: Nowadays superconductors serve in numerous applications, from high-field magnets to ultra-sensitive detectors of radiation. Mesoscopic superconducting devices, i.e. those with nanoscale dimensions, are in a special position as they are easily driven out of equilibrium under typical operating conditions. The out-of-equilibrium superconductors are characterized by non-equilibrium quasiparticles. These extra excitations can compromise the performance of mesoscopic devices by introducing, e.g., leakage currents or decreased coherence times in quantum devices. By applying an external magnetic field, one can conveniently suppress or redistribute the population of excess quasiparticles. In this article we present an experimental demonstration and a theoretical analysis of such effective control of quasiparticles, resulting in electron cooling both in the Meissner and vortex states of a mesoscopic superconductor. We introduce a theoretical model of quasiparticle dynamics which is in quantitative agreement with the experimental data.

description: We present the abundance analysis for a sample of 7 red giant branch stars in the metal-poor globular cluster NGC 4372 based on UVES spectra acquired as part of the Gaia-ESO Survey. This is the first extensive study of this cluster from high resolution spectroscopy. We derive abundances of O, Na, Mg, Al, Si, Ca, Sc, Ti, Fe, Cr, Ni, Y, Ba, and La. We find a metallicity of [Fe/H] = -2.19 $\pm$ 0.03 and find no evidence for a metallicity spread. This metallicity makes NGC 4372 one of the most metal-poor galactic globular clusters. We also find an α-enhancement typical of halo globular clusters at this metallicity. Significant spreads are observed in the abundances of light elements. In particular we find a Na-O anti-correlation. Abundances of O are relatively high compared with other globular clusters. This could indicate that NGC 4372 was formed in an environment with high O for its metallicity. A Mg-Al spread is also present which spans a range of more than 0.5 dex in Al abundances. Na is correlated with Al and Mg abundances at a lower significance level. This pattern suggests that the Mg-Al burning cycle is active. This behavior can also be seen in giant stars of other massive, metal-poor clusters. A relation between light and heavy s-process elements has been identified.

description: Background: Promoting catch-up growth in malnourished children has health benefits, but recent evidence suggests that accelerated child weight gain increases adult chronic disease risk.Objective: We aimed to determine how birth weight (BW) and weight gain to midchildhood relate to blood pressure (BP) in young adults.Design: We pooled data from birth cohorts in Brazil, Guatemala, India, the Philippines, and South Africa. We used conditional weight (CW), a residual of current weight regressed on prior weights, to represent deviations from expected weight gain from 0 to 12, 12 to 24, 24 to 48 mo, and 48 mo to adulthood. Adult BP and risk of prehypertension or hypertension (P/HTN) were modeled before and after adjustment for adult body mass index (BMI) and height. Interactions of CWs with small size-for-gestational age (SGA) at birth were tested.Results: Higher CWs were associated with increased BP and odds of P/HTN, with coefficients proportional to the contribution of each CW to adult BMI. Adjusted for adult height and BMI, no child CW was associated with adult BP, but 1 SD of BW was related to a 0.5-mm Hg lower systolic BP and a 9% lower odds of P/HTN. BW and CW associations with systolic BP and P/HTN were not different between adults born SGA and those with normal BW, but higher CW at 48 mo was associated with higher diastolic BP in those born SGA.Conclusions: Greater weight gain at any age relates to elevated adult BP, but faster weight gains in infancy and young childhood do not pose a higher risk than do gains at other ages.

SOME ANALYTIC AND GEOMETRIC ASPECTS OF THE P-LAPLACIAN ON RIEMANNIAN MANIFOLDS
Creators: name: VERONELLI, GIONA
Publisher: name: Universit� degli Studi di Milano

description: In this thesis, we deal with some problems related to the existence, uniqueness and triviality of the p-harmonic representative in the homotopy class of a map. In the first part, we prove that a map f with finite p-energy, p>2, from a complete Riemannian manifold M into a non-positively curved, compact manifold N is homotopic to a constant, provided the negative part of the Ricci curvature of the domain manifold is small in a suitable spectral sense. The result relies on a Liouville-type theorem for finite q-energy, p-harmonic maps under spectral assumptions. In the second part, we prove some comparison theorem for p-harmonic maps when the domain manifold is p-parabolic. First, we prove that, in general, given a p-harmonic map F from M to N and a convex real function H defined on N, the composition $H\circ F$ is not p-subharmonic, if p>2. This answers in the negative an open question arisen from a paper by Lin and Wei and suggests that the standard techniques used in the harmonic case can not be trivially adapted to $p\neq 2$. Then, we prove comparison results for the p-laplacian in the special case of both real-valued and vector-valued maps with finite p-energy. Finally, we obtain a general comparison result for homotopic finite p-energy continuous p-harmonic maps u and v, assuming that M is p-parabolic and N is complete and non-positively curved. In particular, we construct a homotopy through constant p-energy maps, which turn out to be p-harmonic when N is compact. Moreover, we obtain uniqueness in the case of negatively curved N. This generalizes a well known result in the harmonic setting due to R. Schoen and S.T. Yau.
