description: A recently generated theoretical line list of C II dielectronic recombination lines together with observational data gathered from the literature is used to investigate the electron temperature in a range of astronomical objects, mainly planetary nebulae. The electron temperature is obtained by a least-squares optimisation using all the reliable observed lines in each object. In addition, the subset of lines arising directly from autoionising states is used to directly determine the free-electron energy distribution which is then compared with various theoretical possibilities. The method described here can potentially determine whether there are departures from Maxwell-Boltzmann distributions in some nebulae, as has been recently proposed. Using published observations of the three planetary nebulae where the relevant lines are recorded, we find that the data are best matched by Maxwell-Boltzmann distributions but that the uncertainties are sufficiently large at present that kappa-distributions or two-component nebular models are not excluded.

description: Magnetopause flux ropes (FRs) play a crucial role in the transport of energy and plasma from the solar wind to the Earth's magnetosphere. Once formed by multiple X-line reconnection, the FRs move poleward, during which they can coalesce with each other through a re-reconnection process. The poleward moving FRs eventually coalesce into the cusp regions, through another re-reconnection process. In this paper, using three-dimensional (3-D) global hybrid simulations, we study the two re-reconnection processes of magnetopause FRs by examining the topological changes of magnetic field lines. These re-reconnection processes are essentially 3-D. Two FRs coalesce with each other and form two new FRs (instead of one new FR in the two-dimensional regime). When FRs move close to the cusp region, their field lines can reconnect with the cusp field lines so that the FRs can break into two shorter ones. The two re-reconnection processes increase the plasma energy and the magnetic flux connected to the Earth, which favors particle and energy transport toward the Earth's magnetosphere.

description: When a two-level quantum dot and a plasmonic metal nanoantenna are resonantly coupled by the electromagnetic near field, the system can exhibit a Fano resonance, resulting in a transparency dip in the optical spectrum of the coupled system. We calculate the nonlinear response of such a system, for illumination both by continuous-wave and ultrafast pulsed lasers, using both a cavity quantum electrodynamics and a semiclassical coupled-oscillator model. For the experimentally relevant case of meV thermal broadening of the quantum-dot transition, we predict that femtosecond pulsed illumination can lead to a reversal of the Fano resonance, with the induced transparency changing into a superscattering spike in the spectrum. This ultrafast reversal is due to a transient change in the phase relationship between the dipoles of the plasmon and the quantum dot. It thus represents a new approach to dynamically control the collective optical properties and coherence of coupled nanoparticle systems.

description: Mit dem Ausbau der Offshore-Windenergie werden vermehrt auch ermüdungsbeanspruchte Betonkonstruktionen unter permanentem Wassereinfluss entstehen. Als ein wesentlicher Unterschied zu Onshore-Bauwerken resultiert aus der Offshore-Exposition ein deutlich erhöhter Wassergehalt im Beton. Obwohl in der Literatur vergleichsweise wenige Untersuchungen zum Ermüdungsverhalten von Beton unter Wasser dokumentiert sind, zeigt sich trotz unterschiedlicher Prüfrandbedingungen eine weitgehend einheitliche Tendenz, nämlich, dass unter Wasser geprüfte Betonproben einen erheblich geringeren Ermüdungswiderstand aufweisen als vergleichbare Proben, die an Luft geprüft wurden. Inzwischen ist das Phänomen wasserinduzierter Schädigung bei der Betonermüdung zwar prinzipiell erkannt, jedoch ist es noch längst nicht hinreichend genau verstanden und beschrieben. Das Ziel dieser Arbeit ist es, wasserinduzierte Schädigungsmechanismen ermüdungsbeanspruchter Betone zunächst mit ergänzenden experimentellen Methoden genauer als bisher zu erfassen, zu analysieren und zu verstehen. Darauf aufbauend sollen Modelle entwickelt werden, die in der Lage sind, die am Degradationsprozess beteiligten wasserinduzierten Schädigungsmechanismen quantitativ zu erfassen und physikalisch begründet zu beschreiben. Das Ermüdungsverhalten von Beton wird hierbei systematisch für druckschwellbeanspruchte Betone unterschiedlicher Feuchte, Druckfestigkeit und Probengröße untersucht. Zur Analyse der wasserinduzierten Ermüdungsschädigung wurden neben den Bruchlastwechselzahlen die Dehnungs- und Steifigkeitsentwicklungen, die dissipierten Energien und insbesondere die Schallemissionsaktivität betrachtet. Die Ergebnisse zeigen, dass mit zunehmender Feuchte des Betons sein Ermüdungswiderstand offensichtlich erheblich reduziert wird. Aufbauend auf dieser Erkenntnis wurde ein Modellansatz entwickelt und die Einführung feuchteabhängiger Wöhlerlinien vorgeschlagen. Zudem zeigten die Ergebnisse ein beschleunigtes Degradationsverhalten mit steigendem Feuchtegehalt des Betons. Im Falle der Wassersättigung konnte eine Vielzahl von Schallemissionssignalen nahe der Unterspannung nachgewiesen werden, wodurch wasserinduzierte Schädigungen nicht im Belastungszustand, sondern im Entlastungszustand identifiziert wurden. Auf diese Weise lassen sie sich eindeutig von üblichen mechanischen Schädigungen unterscheiden. Mit Hilfe eines neu entwickelten Ingenieurmodells konnte abschießend gezeigt werden, dass die wasserinduzierten Schädigungen mit Wasserumlagerungen und daraus resultierenden Porenwasserdrücken im nanoporösen System des Zementsteins korrelieren.
title: Margulis, Autopoiesis, Gaia

Publisher: name: Electronic Book Review
Year: 2019

description: Clarke opens with a biographical account of his own early encounters with the Gaia concept - and a skepticism he shared with the evolutionary thinker Lynn Margulis, Gaia's second author after the British scientist James Lovelock. Neither an organism nor a single cell, and not really an organic or vitalistic entity, Gaia is better understood, according to Margulis, as "an emergent property of interaction among organisms, the spherical planet on which they reside, and an energy source, the sun." The move away from metaphors and New Age vitalisms tethers Gaia theory more tightly to the sciences. Margulis’s work brings Gaia in line with the autopoietic systems theory of Humberto Maturana and Francisco Varela introduced in the 1970s. This essay is drawn from a preliminary version of several sections from Clarke’s forthcoming book presently entitled Partial Earth: Lynn Margulis, Systems Theory, and the Evolution of Gaia (Fall 2020) and appears here by permission of the University of Minnesota Press.

description: We experimentally demonstrate how thermal properties in an non-equilibrium quantum many- body system emerge locally, spread in space and time, and finally lead to the globally relaxed state. In our experiment, we quench a one-dimensional (1D) Bose gas by coherently splitting it into two parts. By monitoring the phase coherence between the two parts we observe that the thermal correlations of a prethermalized state emerge locally in their final form and propagate through the system in a light-cone-like evolution. Our results underline the close link between the propagation of correlations and relaxation processes in quantum many-body systems.

description: The European Arrest Warrant (EAW) represents the first instrument based on the principle of mutual recognition in criminal matters. Its approval aimed expressly at replacing the lengthy extradition procedures that existed among European countries, in order to achieve a more effective cross-border judicial surrender procedure. According to the statistics concerning the use of the EAW, this goal has been accomplished. Anyway, its great success has risen many issues concerning the correct balance between freedom and security. From this perspective, this PhD Thesis analyses the Framework Decision 2002/584/GAI, the Italian implementation law, as well as the most significant judgments of the Italian Supreme Court and of the European Court of Justice. In the last chapter, the Author focuses on the related problem consisting in the excessive use of the EAW, suggesting the introduction of a proportionality test ? led by the issuing judicial authority as well as by the executing one ? which could represent a suitable path to reach a balance between repressive needs and protection of fundamental rights.

description: We present a fully dynamical model to study the chiral and deconfinement transition of QCD simultaneously. The quark degrees of freedom constitute a heat bath in local equilibrium for both order parameters, the sigma field and a dynamical Polyakov loop. The nonequilibrium evolution of these fields is described by Langevin equations including dissipation and noise. In several quench scenarios we are able to observe a delay in the relaxation times near the transition temperature for a critical point as well as a first-order phase transition scenario. During the hydrodynamical expansion of a hot quark fluid we find a strong enhancement of thermal fluctuations at the first-order transition compared to a scenario with a critical point.

description: It is shown that the spanning set for L^2([0, 1]) provided by the eigenfunctions {sqrt{2} sin(nπx)}_{n=1}^{\infty} of the particle-in-a-box in quantum mechanics provide a very effective variational basis for more general problems. The basis is scaled to [a,b], where a and b are then used as variational parameters. What is perhaps a natural basis for quantum systems confined to a spherical box in R^d, turns out to be appropriate also for problems that are softly confined by U-shaped potentials, including those with strong singularities at r=0. Specific examples are discussed in detail, along with some bound N-boson systems

Year: 2019

description: Like e-books and so much else in digital commerce, the poetry printed out by Instagram give us back the book - stripping away the social features such as reader comments, nested conversations and responses that make a work "viral," or "spreadable." The content of Instagram poetry, to nobody's surprise, is almost always simplistic, inspirational, and emotional. What it spreads. like any other social media, is indistinguishable from from the surveillance infrastructure of digital metadata that allows algorithms to "read" the reader (who is left in the dark). Kathi Inman Berens in this essay puts forward some ways to change that.

description: The twofold degenerate Anderson impurity model [1-4] is investigated and the strong electronic correlations of d-electrons of impurity ion are taken into account by elaborating suitable diagram technique. We discuss the properties of the Slater-Kanamori model [2-4] of d-impurity electrons. After finding the eigenfunctions and eigenvalues of all 16 local states, we determine the local one-particle propagator. Then we construct the perturbation theory around the atomic limit of the impurity ion and obtain the Dyson type equation for the renormalized one-particle propagator. Diagrammatic theory has been developed and correlation function determined. Special diagrammatic approximation was discussed and summation of diagram has been considered.

title: Gothic incest: transgression and counter-hegemony
Creators: name: Diplacidi, Jenny
Publisher: name: University of Kent
Year: 2023

description: In this thesis I will analyze representations of incest in the Gothic from 1764-1847 and argue that the genre’s critical genealogy, beginning with its contemporary reception, has viewed the Gothic as divided into a male tradition or its female counter, and subsequently informed understandings of incest as having distinct meanings produced by their presence in works designated as male or female. Although feminist criticism from the 1970s onwards has demonstrated that women writers articulated subversive views in the Gothic, such analyses have relied on psychological and sociological theories of incest that frequently reproduce gendered divisions and fail comprehensively to address the incest thematic. It is instead essential to do away with the genre’s gendered bifurcation and employ a broad methodological framework that applies the insights in recent work by anthropologists, feminist, social, and queer theorists, geneticists, and legal and social historians to specific incestuous configurations. In so doing, I argue that the genre’s complex depictions and disruptions of eighteenth-century ideologies of gender and sexuality are revealed through incestuous desires, threats, violence and transgressions. This thesis is comprised of five chapters that explore the social, sexual and legal anxieties underlying representations of incest in different family relationships in the Gothic and contextualizes these accounts within analytic lenses suited to the particular kinship bond. It examines the ability of father-daughter incest to offer female sexual agency and to breakdown the exchange of women, and investigates the potential for equality in sibling relationships that troubled contemporary ideas of desire and laws as inherently natural or unnatural. It explores the sexual threats of uncles towards nieces that literalize the female body’s status as property, and how cousin marriage negotiated the changing status of family and the conflict between individual desires and obligation to the family as state. It analyzes how mother-son incest exposes the inadequacy of available gender and sexual ideologies to account for female desire, agency and aggression. Through these analyses I argue that Gothic writers use the incest convention in order to reveal the arbitrary legal, economic and social limitations on behaviour that are enforced by heteronormative culture and offer alternative models of family, sexuality and desire that counter the hegemony.

description: This is an informal essay, not a paper. There are simply too many questions and few answers. The text was assembled from notes from my keynote conference at ELO 2018 in Montreal ("Mind the Gap!"), where I have experimented with a tentative form of performing theory, possibly pushing the limits of Walter Benjamin's desire to write a book made of quotations only. Also, as with all things, this is an incomplete account of the use of humor and constraint in electronic literature. Many examples just simply could not be included here, and it is not my intention to perform close-readings of any of these works either. My goal is simply to create a narrative that signals how humor is related to constraint in art and technology. Perhaps we can prepare an Anthology of Humorous Electronic Literature together? Also, some disambiguation is in order: this is not about computational humor, or the use of computers in humor research, or about jokes concerning computers. And this is also not about OuLiPo or other literary works specifically written under constraint.

description: The recent experimental discoveries about excitation energy transfer (EET) in light harvesting antenna (LHA) attract a lot of interest. As an open non-equilibrium quantum system, the EET demands more rigorous theoretical framework to understand the interaction between system and environment and therein the evolution of reduced density matrix. A phonon is often used to model the fluctuating environment and convolutes the reduced quantum system temporarily. In this paper, we propose a novel way to construct complex-valued Gaussian processes to describe thermal quantum phonon bath exactly by converting the convolution of influence functional into the time correlation of complex Gaussian random field. Based on the construction, we propose a rigorous and efficient computational method, the covariance decomposition (CD) and conditional propagation scheme, to simulate the temporarily entangled reduced system. The new method allows us to study the non-Markovian effect without perturbation under the influence of different spectral densities of the linear system-phonon coupling coefficients. Its application in the study of EET in the Fenna-Matthews-Olson (FMO) model Hamiltonian under four different spectral densities is discussed. Since the scaling of our algorithm is linear due to its Monte Carlo nature, the future application of the method for large LHA systems is attractive. In addition, this method can be used to study the effect of correlated initial condition on the reduced dynamics in the future.

description: Droughts and extreme weather events have been highlighting for some years many water management problems, even where water is abundant and social-economic context is advanced, as it happens at our latitudes. It?s important to adopt new, multilevel, inclusive policy-making and management approaches in order to develop governance systems suitable to face current challenges, and consequently to mediate the rising conflicting stakes on water and to make more effective the investment in technological modernization. In this context the case study of droughts events happened in Lombardy region between 2003 and 2007 turned out to be interesting. Developing a conceptual framework and making some interviews, the thesis characterizes the adaptive answer to such events from ?water stakeholders? at the regional level, paying particular attention to irrigation sector. The experiences of participatory water resources management, undertaken in those years, have allowed to the system to respond in emergency, have increased knowledge and social network, have started important remarks within the irrigation sector towards upgrade of innovation. However empirical evidences show that, in order to solve the emerging conflicts and develop an integrated and sustainable water resource management, is important, on the one hand, continuing to invest in participation, on the other hand, create a more stable regulatory framework.

description: Industrial manipulators and parallel robots are often used for tasks, such as drilling or milling, that require three translational, but only two rotational degrees of freedom ("3T2R"). While kinematic models for specific mechanisms for these tasks exist, a general kinematic model for parallel robots is still missing. This paper presents the definition of the rotational component of kinematic constraints equations for parallel robots based on two reciprocal sets of Euler angles for the end-effector orientation and the orientation residual. The method allows completely removing the redundant coordinate in 3T2R tasks and to solve the inverse kinematics for general serial and parallel robots with the gradient descent algorithm. The functional redundancy of robots with full mobility is exploited using nullspace projection.

description: The spin of electrons bound to neutral phosphorus donors in isotopically enriched silicon is a promising candidate for future quantum information processing. In this thesis, the intriguing properties of the associated optical transition, i.e., the donor bound exciton (D0X) transition are investigated by means of high precision laser absorption spectroscopy. The ultra-narrow spectral linewidth of the D0X transition allows for individual optical addressability of the electron spin and the phosphorus nuclear spin which is used to unambiguously quantify the microscopic origin of the enhanced donor electron spin lattice relaxation rate caused by optical excitation. For this purpose, the transient decay of the donor electron polarization is studied via a time-resolved pump-probe absorption spectroscopy technique where a significant shortening of the polarization decay with increasing laser excitation is observed. The theoretical analysis of the complete optically driven donor system shows that this shortening is caused by the creation of free electrons via the ubiquitous D0X Auger recombination. It is shown that, in addition to electron-phonon interaction, the hot Auger electrons relax their excess energy via inelastic collisions with donors and promote the donor electron from the ground state to a spin-mixed excited state giving rise to an Orbach-type spin relaxation mechanism which sets a fundamental limit to the spin relaxation and spin coherence time of optically driven donor systems. Furthermore, the ultra-narrow linewidth of the D0X transition enables the test of fundamental semiconductor physics such as the low temperature behavior of the silicon bandgap and the extraction of material parameters like the Landé g-factors.

description: Cemented carbide tools have become widely established in machining of metallic materials in recent decades. However, due to rising prices of cemented carbide and an imminent scarcity of resources, there is a growing need for an efficient recycling of worn cemented carbide tools. This article presents a novel process chain for the automatic regeneration of cemented carbide tools. The process chain contains the measurement, classification and evaluation of the worn cutting tools as well as the automatic planning and simulation of the grinding process. In comparison to conventional manufacturing of cemented carbide tools the production costs are reduced by up to 50 % and the required resources are decreased significantly.

description: Isotropic quantum cosmological perfect fluid model is studied in the formalism of Rainbow gravity. It is found that the only surviving matter degree of freedom played the role of cosmic time. It is possible to find the wave packet naturally with a suitable choice of the Rainbow functions which resulted from the superposition of the wave functions of the Schr$\ddot{o}$dinger-Wheeler-deWitt equation. The many-worlds interpretation of quantum mechanics is applied to investigate the behavior of the scale factor and the behaviour is found to depend on the operator ordering. It is shown that the model in the Rainbow framework naturally avoids singularity and a bouncing non-singular universe is found.

IMMUNOLOGICAL SIGNATURE IN NA�VE AND SUNITINIB-TREATED SOFT TISSUE SARCOMA PATIENTS: ROLE OF MYELOID CELLS
Creators: name: TAZZARI, MARCELLA
Publisher: name: Universit� degli Studi di Milano
Year: 2014

description: Although designed to directly target cancer cells and tumor associated-vasculature, anti-angiogenic drugs (e.g. sunitinib), have been described to influence tumor-host interactions. Sunitinib is currently in use at our Institute for the treatment of progressive, advanced soft tissue sarcomas (STS) of different histology. However, the systemic and local immune responses and their modulation by anti-angiogenic therapies are unknown in these neoplasms, namely solitary fibrous tumors (SFTs), clear cell sarcoma (CCS) and alveolar soft part sarcoma (ASPS). This thesis aims to shed light on the immunological status of these STS patients and to address the question to which extent sunitinib induces immune modulation in these patients. Thus, my research focused on the characterization of both tumor-infiltrating and circulating immune cells of STS patients. Fine analysis of the immune contexture at the tumor site in na�ve and in sunitinib-treated tumors revealed that myeloid cells, namely tumor-associated macrophages, represent a key component of the tumor microenvironment and that their reprogramming is part of the response to sunitinib treatment. Immune monitoring of circulating cells in these STS patients indicated that circulating myeloid suppressor cells were associated to disease progression and were the major player in mediating the immune-suppressive status in na�ve and in sunitinib-treated SFT patients. Moreover, evidence have been provided that, in sunitinib-treated SFT patients, myeloid suppressor cells may be part of acquired resistance, thus supporting the notion that myeloid cells are the most relevant hurdle in the efficacy of anti-angiogenic treatments. Collectively the results of this thesis shed light on an unappreciated phenomenon of immune dysfunction in STS patients and indicate that in SFTs sunitinib transiently relieves systemic immunosuppression and reprograms the immune microenvironment. Moreover, for the first time, an antigen-specific T cell response has been evidenced in CCS, and, this tumor-specific response has occurred in association to sunitinib-induced immune modulation. Overall, this thesis poses the rationale for the development of immune-based clinical approaches aimed at achieving a more durable disease control in these cancer patients, for which effective medical therapies are still needed.
