Genova: verso un nuovo policentrismo
Creators: name: TERENZI, ALESSANDRA
Publisher: name: Universit� degli studi di Genova
Year: 2022

description: the research aims to investigate the polycentric structure of Genoa with respect to the current situation. The main question is about its identity, tryinfg to understand whether, in the light of current transformations, it is more appropriate to define Genoa as a polycentric city or, rather, a city with many centers. To this end, the research will also try to critically reconsider the most widespread and shared model of urban polycentrism, based on specific characteristics and linked to the creation of new centralities able of attract new inhabitants of the creative upper class, proposing instead an alternative reading to the current dominant, based on the idea that the concept of polycentrism does not represent a univocal formula, applicable and desirable in the same way everywhere, assuming, rather, different conformations and multiple meanings, in relation to the different contextual realities in which it could take shape.

description: Literature data on the properties of DNA open states are reviewed and analyzed. These states are formed as a result of strong DNA fluctuations and have a great impact on a number of biochemical processes; among them is charge transfer in DNA, for example. A comparative analysis of experimental data on the kinetics and thermodynamics of DNA open states for a wide temperature range was carried out. Discrepancies between the results of various experiments have been explained. Three types of DNA open states are recognized based on their differences in thermodynamic properties and other characteristics. Besides, an up-to-date definition of the term "open state" is given. A review is carried out for simple mathematical models of DNA in most of which the state of one pair is described by one or two variables. The main problems arising in theoretical investigations of heterogeneous DNA in the framework of models of this level are considered. The role of each group of models in interpretation of experimental data is discussed. Special consideration is given to the studies of the transfer and localization of the nucleotide pairs oscillations' energy by mechanical models. These processes are shown to play a key role in the dynamics of a heterogeneous duplex. Their theoretical interpretation is proven to be very important for the development of modern molecular biology and biophysics. The main features of the theoretical approaches are considered which enabled describing various experimental data. Prospects of the models' development are described, particular details of their optimization are suggested, and possible ways of modernization of some experimental techniques are discussed.

description: Five new isolates of archaeal coccoid thermoacidophiles were obtained from Icelandic solfataric fields. They are strict chemolithoautotrophs gaining energy by oxidation of S° and sulfidic ores. The new strains grow between 50 and 75 °C and p H 1 and 4.5 and tolerate N a C l concentrations of up to 3.0%. The G C - content of their D N A is 38 m o l % . The new isolates resemble members of Sulfolobus in their morphology, their ability to oxidize reduced sulfur compounds and their GC-content. They are different in their strictly chemolithoautotrophic mode of life, their ore-leaching capacity, D N A / D N A hybridization and incomplete serological cross-reaction of R N A polymerase. Therefore, we describe here a new species, Sulfolobus metallicus. Type strain is Sulfolobus metallicus (Kra 2 3 ; D S M 6482).
Towards the core of the cosmological constant problem

description: We apply a new self-tuning mechanism to the well-known Kachru-Kallosh-Linde-Trivedi (KKLT) model to address the cosmological constant problem. In this mechanism the cosmological constant $λ$ contains a supersymmetry breaking term ${\mathcal E}_{\rm SB}$ besides the usual scalar potential ${\mathcal V}_{\rm scalar}$ of the $N=1$ supergravity, which is distinguished from the usual theories where $λ$ is directly identified with ${\mathcal V}_{\rm scalar}$ alone. Also in this mechanism, whether $λ$ vanishes or not is basically determined by the tensor structure of the scalar potential density, not by the zero or nonzero values of the scalar potential itself. As a result of this application we find that the natural scenario for the vanishing $λ$ of the present universe is to take one of the AdS (rather than dS) vacua of KKLT as the background vacuum of our present universe. This AdS vacuum scenario has more nice properties as compared with dS vacua of the usual flux compctifications. The background vacuum is stable both classically and quantum mechanically (no tunneling instabilities), and the value $λ=0$ is also stable against quantum corrections because in this scenario the perturbative corrections of ${\mathcal V}_{\rm scalar}$ and quantum fluctuations $δ_Q {\hat I}_{\rm brane}^{(NS)} + δ_Q {\hat I}_{\rm brane}^{(R)}$ on the branes are all gauged away by an automatic cancelation between ${\mathcal V}_{\rm scalar} + δ_Q {\hat I}_{\rm brane}^{(NS)} + δ_Q {\hat I}_{\rm brane}^{(R)}$ and ${\mathcal E}_{\rm SB}$.

description: Let $f(x)=x^TAx+2a^Tx+c$ and $h(x)=x^TBx+2b^Tx+d$ be two quadratic functions having symmetric matrices $A$ and $B$. The S-lemma with equality asks when the unsolvability of the system $f(x)<0, h(x)=0$ implies the existence of a real number $μ$ such that $f(x) + μh(x)\ge0, ~\forall x\in \mathbb{R}^n$. The problem is much harder than the inequality version which asserts that, under Slater condition, $f(x)<0, h(x)\le0$ is unsolvable if and only if $f(x) + μh(x)\ge0, ~\forall x\in \mathbb{R}^n$ for some $μ\ge0$. In this paper, we show that the S-lemma with equality does not hold only when the matrix $A$ has exactly one negative eigenvalue and $h(x)$ is a non-constant linear function ($B=0, b\not=0$). As an application, we can globally solve $\inf\{f(x)\vert h(x)=0\}$ as well as the two-sided generalized trust region subproblem $\inf\{f(x)\vert l\le h(x)\le u\}$ without any condition. Moreover, the convexity of the joint numerical range $\{(f(x), h_1(x),\ldots, h_p(x)):~x\in\Bbb R^n\}$ where $f$ is a (possibly non-convex) quadratic function and $h_1(x),\ldots,h_p(x)$ are affine functions can be characterized using the newly developed S-lemma with equality.

Nonlinear waves in networks: a simple approach using the sine-Gordon equation

description: To study the propagation of nonlinear waves across Y- and T-type junctions, we consider the 2D sine--Gordon equation as a model and study the dynamics of kinks and breathers in such geometries. The comparison of the energies reveals that the angle of the fork plays no role. Motivated by this, we introduce a 1D effective equation whose solutions agree well with the 2D simulations for kink and breather solutions. For branches of equal width, breather crossing occurs approximately when $v > 1 - ω$, where $v$ is the breather celerity and $ω$ is its frequency. We then characterize the breathers in the two upper branches by estimating their velocity and frequency. These new breathers are slower than the initial breather and up-shifted in frequency. In perspective, this study could be generalized to more complex nonlinear waves.

Double-distribution-function discrete Boltzmann model for combustion

description: A 2-dimensional discrete Boltzmann model for combustion is presented. Mathematically, the model is composed of two coupled discrete Boltzmann equations for two species and a phenomenological equation for chemical reaction process. Physically, the model is equivalent to a reactive Navier-Stokes model supplemented by a coarse-grained model for the thermodynamic nonequilibrium behaviours. This model adopts 16 discrete velocities. It works for both subsonic and supersonic combustion phenomena with flexible specific heat ratio. To discuss the physical accuracy of the coarse-grained model for nonequilibrium behaviours, three other discrete velocity models are used for comparisons. Numerical results are compared with analytical solutions based on both the first-order and second-order truncations of the distribution function. It is confirmed that the physical accuracy increases with the increasing moment relations needed by nonequlibrium manifestations. Furthermore, compared with the single distribution function model, this model can simulate more details of combustion.

Modelling disability trajectories over the disease course in Multiple Sclerosis patients
Creators: name: GALLO, FABIO
Publisher: name: Universit� degli studi di Genova
Year: 2018

description: Background: Multiple Sclerosis (MS) is a chronic autoimmune disease that attacks the CNS. The immune attack on the CNS cause the damage of a substance, called myelin, which surrounds and protects the nerve fibres. MS is one of the most common causes of neurological disability in young adults. It is well established that axonal injury is a feature of multiple sclerosis (Charcot JM, 1880), that the extent of axonal injury is correlated with the degree of inflammation (Trapp BD, 1998) at least in relapsing multiple sclerosis, and that a close association between inflammation and neurodegeneration might exist in all disease stages of multiple sclerosis (Kutzelnigg A, 2005; Frischer J, 2009). However, the interdependence between focal inflammation, diffuse inflammation and neurodegeneration, and their relative contribution to clinical deficits remain ambiguous. Nevertheless, this point is central for understanding the mechanism of tissue injury in multiple sclerosis, which may have an effect on treatment. It has therefore been suggested that disability accrual at later MS stages is primarily driven by neurodegeneration and is largely independent of inflammation. These observations have led to a two-stage hypothesis, with the first stage representing a therapeutic window for modifying disease trajectory, which then becomes uniform in the second stage of disease (Leray E, 2010). This concept was also confirmed in others studies (Scalfari A, 2010; Stys PK, 2012).

description: Complex networks provide a powerful mathematical representation of complex systems in nature and society. To understand complex networks, it is crucial to explore their internal structures, also called structural regularities. The task of network structure exploration is to determine how many groups in a complex network and how to group the nodes of the network. Most existing structure exploration methods need to specify either a group number or a certain type of structure when they are applied to a network. In the real world, however, not only the group number but also the certain type of structure that a network has are usually unknown in advance. To automatically explore structural regularities in complex networks, without any prior knowledge about the group number or the certain type of structure, we extend a probabilistic mixture model that can handle networks with any type of structure but needs to specify a group number using Bayesian nonparametric theory and propose a novel Bayesian nonparametric model, called the Bayesian nonparametric mixture (BNPM) model. Experiments conducted on a large number of networks with different structures show that the BNPM model is able to automatically explore structural regularities in networks with a stable and state-of-the-art performance.

description: In this thesis study, it was investigated the flora of the Derinöz Dam Lake (Amasya) surroundings and the elevation caused variations in the quantities of the essential oil of certain medicinal plants of the research area. 406 species, subspecies and varieties belonging 223 genera and 63 families identified at the research area. 52 of the 406 taxa are endemic with a 12,8% endemism rate. The scattering ratios of the taxa according to the phytogeographical regions were as follows: 19,70% Euro – Siberian (80 taxa), 17,48% Irano – Turanian (70 taxa), 7,63% Mediterrenean (31 taxa) and 55,42% (225 taxa) was pluriregional or unknown. The ranking of the top 5 richest plant families according to the included taxa number were Asteraceae (13,05%, 53 taxa), Fabaceae (10,59%, 43 taxa), Lamiaceae (10,59%, 43 taxa), Caryophyllaceae (6,40%, 26 taxa) and Brassicaceae (5,42%, 22 taxa). 6 taxa, traditionally used as medicinal purposes, were investigated in terms of the elevation caused variations in the quantity of the essential oil. A decline inversely proportional to the elevation determined in the essential oil quantity of the Hypericum montbretii Spach (375%), Hypericum orientale L. (142%), Nepeta nuda L. subsp. albiflora (Boiss.) Gams (37%) and Mentha longifolia subsp. (L.) Hudson longifolia (L.) Hudson (46%) when compared the populations at the highest elevation and the lowest elevation. On the contrary, Achillea biebersteinii Afan (206%) and Achillea millefolium L. subsp. millefolium L. (%22) showed an increase directly proportional to elevation in terms of the essential oil quantities of the populations at the highest elevation and the lowest elevation.

description: A generalized Bloch sphere, in which the states of a quantum entity of arbitrary dimension are geometrically represented, is investigated and further extended, to also incorporate the measurements. This extended representation constitutes a general solution to the measurement problem, inasmuch it allows to derive the Born rule as an average over hidden-variables, describing not the state of the quantum entity, but its interaction with the measuring system. According to this modelization, a quantum measurement is to be understood, in general, as a tripartite process, formed by an initial deterministic decoherence-like process, a subsequent indeterministic collapse-like process, and a final deterministic purification-like process. We also show that quantum probabilities can be generally interpreted as the probabilities of a first-order non-classical theory, describing situations of maximal lack of knowledge regarding the process of actualization of potential interactions, during a measurement.

description: Quantum mechanics predicts superposition of position states even for macroscopic objects. Recently, the use of a quasi-freely suspended mirror combined with laser was proposed to prepare such states, by Müller-Ebhardt et al. [Phys.Rev.Lett.100, 013601 (2008)]. One of the key milestones towards this goal is the preparation of the mechanical oscillator mainly driven by quantum back-action, which identifies the connection between the object and quantumness of the light. Here, we describe development of a suspended 5-mg mirror driven by quantum back-action larger than thermal fluctuating force by a factor of 1.4$\pm$0.2 at 325 Hz,which is confirmed by using a triangular optical cavity.

description: The biomedical applications of carbon nanomaterials are under intensive investigation for the development of next-generation therapeutics. Although much focus has been placed on carbon nanotubes (CNTs) and graphene, other carbon nanomaterials including carbon nanohorns (CNHs), nanodiamonds (NDs) and fullerenes have emerged as suitable candidates for biomedical applications. Among these multi-shell fullerenes, also known as carbon nano-onions (CNOs), are the less studied carbon nanomaterials in biomedicine. The unique properties of carbon nano-onions, such as high surface area-to-volume ratio, thermal conductivity, electrical conductance, mechanical stiffness and ease of chemical functionalization render them fascinating materials for diverse applications including drug-delivery, diagnostics, biological imaging and tissue engineering. Carbon nanomaterials are emerging as smart nanostructures for biomedicine due to the possibility to incorporate multiple functionalities and moieties internally or externally. They can be modified at a precise physicochemical level to optimize targeting in the complex in vivo environment and also engineered for fluorescence detection, magnetic resonance imaging and ablation of tumor cells. Herein, robust and versatile synthetic strategies for the modification of carbon nano-onions (CNOs) are reported. The development of novel CNO conjugates represent a promising platform for the realization of novel technology scaffold for molecular imaging, photodynamic therapy and molecular transporter of fully synthetic carbohydrate-based vaccines for immunotherapy due to the large specific surface area and unique optical and electrochemical properties of CNOs. Through the methodologies described, these smart nano-materials can envisage the realization of multi stimuli-responsive and dynamic architectures capable of changing their physicochemical behavior upon encountering specific microenvironmental signals becoming relevant for diagnosis, imaging and therapies of specific disease applications.

For a large class of finitary $2$-categories we prove that simple transitive $2$-representations are exhausted by cell $2$-representations. Finally, we show that this large class contains finitary quotients of $2$-Kac-Moody algebras.

description: Vittorio Colao was appointed Chief Executive of Vodafone Group plc on 29 July 2008. Given the ongoing economic tumult, one of his first acts as CEO was to stress that the company had to 'batten down the hatches' to survive. The days of multi-billion pound deals were over, he added. Vittorio inherited a global business present in more than 70 different countries, either through owned subsidiaries or partnerships. Vodafone had a very fast-growing subscriber base, but also some significant profitability sensitivities. A key document awaiting Vittorio's attention presented performance indicators for Vodafone's businesses in several continents. Hot topics included the future of Vodafone's partnership with Verizon in the United States, European countries' operational performance and the group's strong growth in emerging markets. Growth in subscribers, which is an important performance indicator in the telecom industry, was mainly thanks to Vodafone's acquisitions in emerging markets such as Turkey, India and South Africa. But some of these markets were also hurting the business. In Turkey, for example, Vodafone was forced to write down a GBP 2.25bn loss, mainly because upgrading the mobile network was taking much longer than expected and the group was struggling to compete with the local market leader. Turkey remained one of the most interesting markets for Vodafone, with a growing population, comparatively low penetration and new openings in the regulatory field, but Vodafone was losing market share every day. Vittorio Colao had many big calls to make, and quickly - and one of the biggest was what to do about Turkey.

description: We consider the problem of inferring the total causal effect of a single variable intervention on a (response) variable of interest. We propose a certain marginal integration regression technique for a very general class of potentially nonlinear structural equation models (SEMs) with known structure, or at least known superset of adjustment variables: we call the procedure S-mint regression. We easily derive that it achieves the convergence rate as for nonparametric regression: for example, single variable intervention effects can be estimated with convergence rate $n^{-2/5}$ assuming smoothness with twice differentiable functions. Our result can also be seen as a major robustness property with respect to model misspecification which goes much beyond the notion of double robustness. Furthermore, when the structure of the SEM is not known, we can estimate (the equivalence class of) the directed acyclic graph corresponding to the SEM, and then proceed by using S-mint based on these estimates. We empirically compare the S-mint regression method with more classical approaches and argue that the former is indeed more robust, more reliable and substantially simpler.

description: Staking layered materials revealed to be a very powerful method to tailor their electronic properties. It has indeed been theoretically and experimentally shown that twisted bilayers of graphene (tBLG) with a rotation angle $θ$, forming Moiré pattern, confine electrons in a tunable way as a function of $θ$. Here, we study electronic structure and transport in tBLG using tight-binding numerical calculations in commensurate twisted bilayer structures and a pertubative continuous theory, which is valid for not too small angles ($θ> \sim 2^\circ $). This two approaches allow to understand the effect of $θ$ on the local density of states, the electron lifetime due to disorder, the dc-conducitivity and the quantum correction of the conductivity due to multiple scattering effects. We distinguished the cases where disorder is equaly distributed in the two layer or only in one layer. When only one layer is disordered, diffusion properties depends strongly on $θ$, showing thus the effect of Moiré electronic localisation at intermediate angles, $\sim 2^\circ < θ< \sim 20^\circ$.

Dopo aver scoperto, l'anno scorso, il potente lampo di raggi gamma Grb 210905A, un team internazionale guidato dall'Inaf ha continuato a osservare per molti mesi il bagliore residuo della sorgente, originatasi dall'esplosione di una stella massiccia quando l'universo aveva meno di 900 milioni di anni. Lo studio di questo raro fenomeno indica che anche i Grb più lontani si comportano in modo simile a quelli a noi vicini. Ne parliamo con Andrea Rossi dell'Inaf di Bologna

Thiobacillus cuprinus sp. nov., a Novel Facultatively Organotrophic Metal-Mobilizing Bacterium.

Publisher: name: Universität Regensburg
Year: 1990

description: Five strains of mesophilic, facultatively organotrophic, ore-leaching eubacteria were isolated from solfatara fields in Iceland and a uranium mine in the Federal Republic of Germany. The new organisms are aerobic gram-negative rods. They can use sulfidic ores or elemental sulfur as sole energy source, indicating that they belong to the genus Thiobacillus. Alternatively, they grow on organic substrates such as yeast extract, peptone, and pyruvate. In contrast to the other leaching bacteria known so far, the new isolates are unable to oxidize ferrous iron. They consist of extreme and moderate acidophiles growing optimally at pH 3 and 4, respectively. The extreme acidophiles showed leaching characteristics similar to those shown by Thiobacillus ferrooxidans, while the moderate acidophiles exhibited a pronounced preference for copper leaching on some chalcopyrite ores. The G+C content of the DNA is between 66 and 69 mol%, depending on the isolate. In DNA-DNA hybridization experiments, the new strains showed homologies among each other of >70%, indicating that they belong to the same species. No significant DNA homology to Thiobacillus reference strains was detectable. Therefore, the new isolates represent a new species of Thiobacillus, which we name Thiobacillus cuprinus. Isolate Hö5 is designated as the type strain (DSM 5495).

description: A polariton Bardeen-Cooper-Schrieffer (BCS) state in a semiconductor microcavity is an example of symmetry-broken states in open systems. Fluctuations of the order parameter are an important tool to characterize such a state. With the condensate formed by composite particles, the set of zero-momentum fluctuations spans an infinite-dimensional electron-hole mode subspace. We show that collective fluctuation modes with orbital angular momentum different from that of the order parameter can be obtained with terahertz radiation, and that a physical manifestation of such modes, which are not Higgs modes, can be terahertz gain.

description: The type strain (ATCC 23270) and two other strains of Thiobacillus ferrooxidans were able to grow by hydrogen oxidation, a feature not recognized before. When cultivated on H2, a hydrogenase was induced and the strains were less extremely acidophilic than during growth on sulfidic ores. Cells of T. ferrooxidans grown on H2 and on ferrous iron showed 100% DNA homology. Hydrogen oxidation was not observed in eight other species of the genus Thiobacillus and in Leptospirillum ferrooxidans.

description: It was shown by Le Jan that the occupation field of a Poisson ensemble of Markov loops ("loop soup") of parameter one-half associated to a transient symmetric Markov jump process on a network is half the square of the Gaussian free field on this network. We construct a coupling between these loops and the free field such that an additional constraint holds: the sign of the free field is constant on each cluster of loops. As a consequence of our coupling we deduce that the loop clusters of parameter one-half do not percolate on periodic lattices. We also construct a coupling between the random interlacement on $\mathbb{Z}^{d}$, $d\geq 3$, introduced by Sznitman, and the Gaussian free field on the lattice such that the set of vertices visited by the interlacement is contained in a level set of the free field. We deduce an inequality between the critical level for the percolation by level sets of the free field and the critical parameter for the percolation of the vacant set of the random interlacement. Both in the case of loops and of the random interlacement, the couplings are constructed by replacing discrete graphs by metric graphs. Le Jan's and Sznitman's isomorphism theorems between the Gaussian free field and the occupation field of trajectories can be extended to the metric graph setting on which the intermediate value principle for continuous fields holds.

description: The holographic superconductor is one of the most popular models in the context of applied holography. Despite what its name suggests, it does not describe a superconductor. On the contrary, the low temperature phase of its dual field theory is a superfluid with a spontaneously broken U(1) global symmetry. As already observed in the previous literature, a bona fide holographic superconductor can be constructed using mixed boundary conditions for the bulk gauge field. By exploiting this prescription, we study the near-equilibrium collective dynamics in the Higgs phase and reveal the characteristic features of the Anderson-Higgs mechanism. We show that second sound disappears from the spectrum and the gauge field acquires a finite energy gap of the order of the plasma frequency. We observe an overdamped to underdamped crossover for the Higgs mode which acquires a finite energy gap below $\approx T_c/2$, with $T_c$ the superconducting critical temperature. Interestingly, the energy gap of the Higgs mode at low temperature is significantly smaller than $2Δ$, with $Δ$ the superconducting energy gap. Finally, we interpret our results using Ginzburg-Landau theory and we confirm the validity of previously derived perturbative analytic expressions.
