Performance-Based approach in seismic design of embedded retaining walls
Creators: name: Visone, Ciro
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2008

description: The increasing use of the underground spaces and the last seismic events in the urban areas have driven many researchers of different countries to deepen the knowledge on the dynamic behaviour of the structure embedded in the subsoil.
This thesis attempts to give some contributes on the application of the performance based approach for the seismic design of the embedded retaining walls.
After an overview on the earth pressure theories proposed by different authors, the static and seismic design methods commonly adopted in the current practice and based on pseudostatic approaches are recalled.
Several limitations on these procedures can be recognized: the difficulties on the definition of the seismic coefficient; the calculation of the expected earthquake-induced displacements around the construction. Moreover, in the framework of the Performance-Based Design, these methods do not able to describe the response of the retaining systems to a given earthquake. The seismic displacements of the flexible walls are evaluated by means of Newmark sliding block procedures, that were developed for rigid structures, and the yield sequence of the different structural components can not be predicted. Then, the application of the hierarchical resistance criteria in the dimensioning of the various parts can not be applied.
In this thesis, different level of analysis are highlighted in relation to the importance of the structure and to the design phase.
An innovative procedure that can be included in the framework of the "pushover analyses" is also proposed for the seismic design of the embedded retaining walls.
Finally, the results obtained by the application of the different methods for the ideal case study of cantilever diaphragms embedded in dry loose and dense sand are presented. The material properties used in the analyses are referred to the Fraction E (BS 100/170) of the Leighton Buzzard sand, for which a series of triaxial and torsional tests on reconstituted samples was conducted.

description: After recent observational events like the LIGO-Virgo detections of gravitational waves and the shadow image of M87* supermassive black hole by Event Horizon Telescope (EHT), the theoretical study of black holes was significantly improved. Quantities as quasinormal frequencies, shadows, and light deflection become more important to analyze black hole models. In this context, an interesting scenario to study is a black hole in the bumblebee gravity. The bumblebee vector field imposes a spontaneous symmetry breaking that allows the field to acquire a vacuum expectation value that generates Lorentz-Violating (LV) into the black hole. In order to compute the quasinormal modes (QNMs) via the WKB method, we obtain the Reege-Wheeler's equation with a bell-shaped potential for this black hole. Both QNMs, the scalar and tensorial modes, are computed for the black hole in the bumblebee scenario. Moreover, the stability of the Schwarzschild-like solution and some bounds to LV parameters are analyzed.

description: Kitaev spin liquids (KSLs) contain both itinerant Majorana fermions and localized $Z_2$ flux excitations. The mobile fermions transport energy, while the fluxes hinder heat flow. By controlling the flux configuration, one can separate a KSL into different domains via $Z_2$ flux walls. We show that at low temperatures, the wall significantly suppresses the Majorana-mediated Ruderman-Kittel-Kasuya-Yosida (RKKY) interaction and blocks the heat transfer between domains.

description: A key feature of intelligent behaviour is the ability to learn abstract strategies that scale and transfer to unfamiliar problems. An abstract strategy solves every sample from a problem class, no matter its representation or complexity -- like algorithms in computer science. Neural networks are powerful models for processing sensory data, discovering hidden patterns, and learning complex functions, but they struggle to learn such iterative, sequential or hierarchical algorithmic strategies. Extending neural networks with external memories has increased their capacities in learning such strategies, but they are still prone to data variations, struggle to learn scalable and transferable solutions, and require massive training data. We present the Neural Harvard Computer (NHC), a memory-augmented network based architecture, that employs abstraction by decoupling algorithmic operations from data manipulations, realized by splitting the information flow and separated modules. This abstraction mechanism and evolutionary training enable the learning of robust and scalable algorithmic solutions. On a diverse set of 11 algorithms with varying complexities, we show that the NHC reliably learns algorithmic solutions with strong generalization and abstraction: perfect generalization and scaling to arbitrary task configurations and complexities far beyond seen during training, and being independent of the data representation and the task domain.

Publisher: name: Zenodo
Year: 2021

description: Die vorliegende Arbeit untersucht, durch Literaturrecherche, was für Auswirkungen durch die Arbeitswelt 4.0 für die Beschäftigten und das Betriebliche Gesundheitsmanagement (BGM) zu erwarten sind. Denn die digitalen Technologien sind aus dem Arbeitsalltag, aber auch im privaten Umgang nicht mehr wegzudenken. Die Veränderungen, welche die Digitalisierung mit sich bringt, werden unter dem Begriff «Arbeitswelt 4.0» zusammengefasst. Die Corona-Pandemie beschleunigte die Verwendung von Unterstützungs-Softwaren im Arbeitsalltag zusätzlich, weil sich der Arbeitsort von heute auf morgen in die eigenen vier Wände verschoben hat. Bereits vor der Pandemie wurde das Home-Office als neuer Arbeitsort getestet. Da es für Arbeitgebende und Arbeitnehmende Vorteile mit sich bringt, werden die Büroräumlichkeiten umfunktioniert, damit auch ein mobil-flexibles Arbeiten vor Ort möglich ist. Daraus entstehen neue Ressourcen, die sich positiv auf die Gesundheit der Beschäftigten auswirken. Doch die neuen Möglichkeiten bringen auch neue Belastungen mit sich. So fühlen sich Beschäftigte vermehrt gestresst durch das Gefühl, immer erreichbar zu sein. Arbeits- und Privatleben vermischen sich mehr, da keine klare Abgrenzung mehr möglich ist. Zusätzlich ist noch nicht abschliessend geklärt, wie der Gesundheitsschutz der Beschäftigten auch im Home-Office gewährleistet werden kann. Hierfür sind neue gesetzliche, wie auch unternehmensinterne Regelungen notwendig. Dem BGM wird in Zukunft eine noch wichtigere Rolle in der Gesundheitserhaltung und -förderung der Beschäftigten zukommen. Um das komplexe Handlungsfeld der Prävention, Behandlung und Früherkennung zu strukturieren, wird in dieser Arbeit Bezug zur Systemtheorie hergestellt. Werden Präventionsmassnahmen nach der systemtheoretischen Grundlage geplant, angeboten und evaluiert, kann die Wirkungskette abgeleitet und der Erfolg zugeordnet werden. Werden die Erkenntnisse aus der Veränderung durch die Arbeitswelt 4.0 in das BGM integriert, eröffnen sich neue Handlungsfelder auf der Verhaltens- und Verhältnisebene. Dafür sind jedoch finanzielle wie auch personelle Ressourcen erforderlich, um nachhaltige Prävention und Gesundheitsförderung zu betreiben.

description: Dimension-reduction techniques can greatly improve statistical inference in astronomy. A standard approach is to use Principal Components Analysis (PCA). In this work we apply a recently-developed technique, diffusion maps, to astronomical spectra for data parameterization and dimensionality reduction, and develop a robust, eigenmode-based framework for regression. We show how our framework provides a computationally efficient means by which to predict redshifts of galaxies, and thus could inform more expensive redshift estimators such as template cross-correlation. It also provides a natural means by which to identify outliers (e.g., misclassified spectra, spectra with anomalous features). We analyze 3835 SDSS spectra and show how our framework yields a more than 95% reduction in dimensionality. Finally, we show that the prediction error of the diffusion map-based regression approach is markedly smaller than that of a similar approach based on PCA, clearly demonstrating the superiority of diffusion maps over PCA for this regression task.

description: The article analyses one of the stories given in the Chronicle by John of Nikiu (late 7th century AD), namely that of Alexander the Great. The author shows that although the information on the Macedonian king was taken by the chronicler mainly from the writing by John Malalas (6th century AD), he also used in this connection а number of other sources. Unfortunately, it is impossible to identify them. John of Nikiu employed these sources either to supplement or correct, when he considered it necessary, the material he found in Malalas.

description: L’architettura non occupa spazi ma trasforma ambienti, intervenendo su una complessa rete di relazioni su molteplici livelli: estetico - percettivi, semantici, culturali, sociali, energetici. La banalizzazione del ruolo dell’architetto è uno degli aspetti fenomenici della rottura dell’antica alleanza fra uomo e natura, una frattura che è soprattutto semantica, giacché l’architetto ha smarrito il bisogno e la capacità di leggere il territorio sul quale interviene, nella molteplicità delle sue manifestazioni: una molteplicità che richiede, finalmente, una prospettiva integrata e una presa di coscienza completa. Tale acquisizione non può che passare, come indica Jonas, attraverso un’assunzione di responsabilità che è, a sua volta, inattuabile se non si risolvono due nodi: l’ineluttabilità della relazione fra l’uomo e quanto lo circonda e i termini di questa relazione, soprattutto dal punto di vista ecologico. Questa ricerca si propone di fornire strumenti per la comprensione degli aspetti estetico-percettivi, segnici ed ecologici del territorio in una visione olistica che possa avvalersi del contributo di più discipline - dalla biologia all’antropologia filosofica, dalla fisica all’economia – per suggerire nuovi modelli di relazione tra contesto e architettura, affinché quest’ultima, strumento di trasformazione del territorio per eccellenza, possa rinnovare il proprio ruolo nella costruzione dell’ecumene, della casa degli uomini.

description: The aim of the systematic review was to assess recently published studies on diagnostic test accuracy of glioblastoma treatment response monitoring biomarkers in adults, developed through machine learning (ML). Articles were searched for using MEDLINE, EMBASE, and the Cochrane Register. Included study participants were adult patients with high grade glioma who had undergone standard treatment (maximal resection, radiotherapy with concomitant and adjuvant temozolomide) and subsequently underwent follow-up imaging to determine treatment response status. Risk of bias and applicability was assessed with QUADAS 2 methodology. Contingency tables were created for hold-out test sets and recall, specificity, precision, F1-score, balanced accuracy calculated. Fifteen studies were included with 1038 patients in training sets and 233 in test sets. To determine whether there was progression or a mimic, the reference standard combination of follow-up imaging and histopathology at re-operation was applied in 67% of studies. The small numbers of patient included in studies, the high risk of bias and concerns of applicability in the study designs (particularly in relation to the reference standard and patient selection due to confounding), and the low level of evidence, suggest that limited conclusions can be drawn from the data. There is likely good diagnostic performance of machine learning models that use MRI features to distinguish between progression and mimics. The diagnostic performance of ML using implicit features did not appear to be superior to ML using explicit features. There are a range of ML-based solutions poised to become treatment response monitoring biomarkers for glioblastoma. To achieve this, the development and validation of ML models require large, well-annotated datasets where the potential for confounding in the study design has been carefully considered.

description: A substantial literature explains the adoption of climate change acts and their impact on climate policy once adopted. In contrast, we know very little about the processes leading to the non-adoption of climate change acts and the subsequent consequences for climate policymaking. This contribution aims at filling this gap by analysing the non-adoption of the Belgian bill for a climate change law. Proposed in February 2019, the Belgian bill for a climate change law was debated but then rejected very soon after, at the end of March 2019. Taking the non-adoption of the Belgian bill on climate change as an enlightening case study, this contribution investigates the impact of climate change act non-adoption on climate policies by: (i) questioning how climate change acts are drafted, and the role of academic experts for such a task in a context of climate emergency; (ii) analysing the reception and discussion of the bill on climate action, including within civil society; and (iii) tracing the follow-up actions undertaken in the wake of the bill’s non-adoption. The research relies on documentary analysis (climate change act drafts and final text, parliamentary discussions, non-governmental organizations’ archives), interviews with key actors and an exploratory questionnaire with climate activists. Although it was not adopted, we argue that the climate change act project has opened new opportunities to rethink expertise and climate mobilization in Belgium. Key Policy InsightsEven when climate change bills fail, they can still have important political or policy effects in the future by raising awareness for the impacts of climate change.When proposing new laws, academic experts should be well informed about the timing and conditions of the political agenda.Consultations with civil society on climate change law projects would increase public awareness and pressure for adoption.Including other important societal causes related to social, economic, decolonial and gender issues, would be key to broadening the impact of the climate movement.

description: We investigate the dynamics of super-inflation in two versions of Loop Quantum Cosmology, one in which the Friedmann equation is modified by the presence of inverse volume corrections, and one in which quadratic corrections are important. Computing the tilt of the power spectrum of the perturbed scalar field in terms of fast-roll parameters, we conclude that the first case leads to a power spectrum that is scale invariant for steep power law negative potentials and for the second case, scale invariance is obtained for positive potentials that asymptote to a constant value for large values of the scalar field. It is found that in both cases, the horizon problem is solved with only a few e-folds of super-inflationary evolution.

The role of spatial pattern learing in hummingbird foraging
Creators: name: Sutherland, Glenn D.
Publisher: name: University of British Columbia
Year: 2010

description: Foraging efficiently requires that animals organize their behaviour in relation to spatial and temporal patterns of food distribution and abundance. This thesis examines how hummingbirds use information about spatial food distributions in their foraging behaviour. I used laboratory tests with large arrays of feeders to clarify the role of learning and memory for spatial location in hummingbird -foraging and to identify constraints on these abilities. The main questions were: "What characteristics of the spatial patterning of food supply constrain hummingbird foraging success?"; and "To what extent are learning and spatial memory important in determining where hummingbirds forage?". Hummingbirds learned to visit the most profitable feeders in large two dimensional arrays in which the only source of information to feeder quality was provided by spatial location. These arrays had equal numbers of profitable feeders and the same total energy available; they differed in the spatial arrangement of food. Birds learned more quickly and reached somewhat higher levels of performance on arrays of a few large groups of feeders than on those with a larger number of smaller groups. However, hummingbirds also learned to perform well even in complex arrays, but they performed consistently well only if the feeders were regularly distributed. Memory for the location of feeder groups was more important in accounting for performance in these experiments than learning individual locations or simple movement rules. In experiments in which I switched the distribution of food to its mirror-image after birds had reached asymptotic performance, all birds showed a lag in redistributing their foraging effort. There was little evidence that the birds re-learned the new distribution faster after the switch than in the initial learning phase. A detailed analysis of movements made in a complex array suggests that hummingbirds avoided visits to bad feeders by organizing their visits within and among small patches. These results are consistent with a model of hummingbird spatial information-processing in which feeder quality is "mapped" into a coarse-grained set of expectations that becomes stable and can persist in spite of changes in the underlying distribution of food. The principal effect of complexity is to reduce the rate of learning distributions of feeder quality; all of the patterns I used could be learned by the birds although birds did reach higher levels of performance on the simplest than on other patterns.

Установлено, что образ Нерона, отображенный автором «Хроники», представляет собой оригинальный эпизод, отсутствующий в источниках, которые исследователи ранее включали в число использованных Иоанном Никиуским при подготовке своего труда. Выполнено сравнение образа Нерона, отображенного Иоанном Никиуским с образами, получившими отражение в произведениях античной и раннехристианской историографии. Проведены параллели эпизода, связанного с мнимой беременностью Нерона с аналогичным эпизодом, содержащимся в «Золотой легенде» Иакова Ворагинского (XIII в.).
description: The article is dealing with the image of Emperor Nero in the Chronicle written by John, the Bishop of Nikiu, in the late 7th century. It is cleared out that the image of Nero depicted by the author of the Chronicle is an original episode which is absent in the sources that scholars previously included among those used by John of Nikiu when he prepared his work. The image of Nero given by John of Nikiu is compared with the images reflected in the works of Ancient and early Christian historiography. Parallels are drawn between the episode connected with the imaginary pregnancy of Nero, and the similar episode contained in the Golden legend by Jacobus de Voragine (13th century).

description: In this survey, we give a friendly introduction from a graph theory perspective to the q-state Potts model, an important statistical mechanics tool for analyzing complex systems in which nearest neighbor interactions determine the aggregate behavior of the system. We present the surprising equivalence of the Potts model partition function and one of the most renowned graph invariants, the Tutte polynomial, a relationship that has resulted in a remarkable synergy between the two fields of study. We highlight some of these interconnections, such as computational complexity results that have alternated between the two fields. The Potts model captures the effect of temperature on the system and plays an important role in the study of thermodynamic phase transitions. We discuss the equivalence of the chromatic polynomial and the zero-temperature antiferromagnetic partition function, and how this has led to the study of the complex zeros of these functions. We also briefly describe Monte Carlo simulations commonly used for Potts model analysis of complex systems. The Potts model has applications as widely varied as magnetism, tumor migration, foam behaviors, and social demographics, and we provide a sampling of these that also demonstrates some variations of the Potts model. We conclude with some current areas of investigation that emphasize graph theoretic approaches. This paper is an elementary general audience survey, intended to popularize the area and provide an accessible first point of entry for further exploration.

description: In addition to their undisputed success in solving classical optimization problems, neuroevolutionary and population-based algorithms have become an alternative to standard reinforcement learning methods. However, evolutionary methods often lack the sample efficiency of standard value-based methods that leverage gathered state and value experience. If reinforcement learning for real-world problems with significant resource cost is considered, sample efficiency is essential. The enhancement of evolutionary algorithms with experience exploiting methods is thus desired and promises valuable insights. This work presents a hybrid algorithm that combines topology-changing neuroevolutionary optimization with value-based reinforcement learning. We illustrate how the behavior of policies can be used to create distance and loss functions, which benefit from stored experiences and calculated state values. They allow us to model behavior and perform a directed search in the behavior space by gradient-free evolutionary algorithms and surrogate-based optimization. For this purpose, we consolidate different methods to generate and optimize agent policies, creating a diverse population. We exemplify the performance of our algorithm on standard benchmarks and a purpose-built real-world problem. Our results indicate that combining methods can enhance the sample efficiency and learning speed for evolutionary approaches.

Показано, что хотя сведения, касающиеся великого римского императора, хронист черпал главным образом из труда Иоанна Малалы (VI в.), он обращался в данной связи и к ряду других источников, прежде всего к Vita Constantini Евсевия Кесарийского, на что раньше не обращалось внимание, а также агиографическим, таким как «Легенда о святой Евдоксии» и  Синаксарное житие за 28 мегабита из эфиопского синаксаря. К сожалению, ряд других источников определить не представляется возможным. В «Хронике» Иоанна Никиуского обращает на себя внимание сообщение о том, что якобы его отец Констанций Хлор построил Византий, что является результатом орфографической ошибки (Берентийя/Британия превратилась в Безентийя), из которой выросло ее произвольное толкование неизвестным арабоязычным редактором. В образе Константина нетривиальными чертами являются его изначальное христианство, что, возможно, связано с влиянием его синаксарного жития, затем – его крещение папой Сильвестром. Кроме того, необычной особенностью образа Константина является рассказ о его войне с персами.
description: The article is dealing with one of the episodes given in the Chronicle by John of Nikiu (late 7th century), namely with his history of Constantine the Great. The authors of the article show that although the chronicler took the information about the great Roman emperor mainly from the work by John Malalas (6th century), he also used a number of other sources in this connection, first of all, Vita Constanini by Eusebius of Caesarea, which has been neglected by previous scholars, and hagiographic writings, such as the Legend about Holy Eudoxia, as well as the Life of St. Emperor Constantine from the Ethiopian Synaxary. Unfortunately, other sources cannot be identified. A point that attracts attention in the Chronicle by John of Nikiu is his statement that Constantius Chlorus, Constantine’s father, built Byzantium. This, as the authors argue, is a result of an orthographic mistake (Berentya/Britain was transformed into Bezentiya), which gave a basis for such a voluntary interpretation by an unknown Arabic redactor. Special features of the image of Constantine are his original Christianity, which seems to be connected with the influence of Synaxary’s Life of Constantine, and his baptism by pope Silvester. Another non-trivial peculiarity of Constantine’s image is a story on his war with the Persians.
Sintesi e valutazione farmacologica di nuovi ligandi della proteina prionica per il loro impiego nel trattamento delle encefalopatie spongiformi trasmissibili (TSE)
Creators: name: Esposito, Antonella
Publisher: name: Università degli Studi di Napoli Federico II
Year: 2010

description: La proteina prionica è un normale costituente dell'ospite, ubiquitaria nei tessuti dei vertebrati, di cui esistono due isoforme: la forma normale, PrPC, e la forma proteasi-resistente PrPSc specifica della malattia. La principale differenza tra le due è solo conformazionale, in quanto la PrPC contiene esclusivamente alfa eliche, mentre la PrPSc contiene filamenti beta. La malattia da prioni è spiegata dalla teoria prionica, la quale ipotizza che la PrPC sia in grado di ripiegarsi in modo anomalo, originando così il prione patogeno PrPSc. Quest’ultimo ha la capacità di autoreplicarsi e polimerizzare, formando placche amiloidotiche che precipitano sulla superficie dei neuroni provocandone la morte. Sulla base di pregressi studi di relazione struttura-attività, è stata sintetizzata una serie di composti, potenzialmente capaci di inibire la conversione della PrPC in PrPSc. Tali composti sono caratterizzati dalla presenza di un nucleo di varia natura (fenossibenzenico, cicloesilossibenzenico, ecc..), opportunamente sostituito con gruppi con diverse proprietà steriche ed elettroniche, legato, mediante una porzione acetammidica, ad un anello pirrolidinico o piperidinico, e recante una catena alchilica di diversa lunghezza. La sperimentazione farmacologica ha previsto un saggio HTS basato sulla scansione di target intensamente fluorescenti (SIFT, scanning for intensely fluorescent targets) al fine di valutare la capacità dei composti di interferire con l’interazione PrPC-PrPSc a livello molecolare. Successivamente è stata valutata la loro capacità di inibire la propagazione di PrPSc in sistemi cellulari (cellule ScN2a e SMB). L’attività antiprionica è stata riscontrata per la maggior parte dei composti sintetizzati; i dati sono, inoltre, caratterizzati da una significativa concordanza tra i risultati forniti dai due tipi di saggio.

description: We study the critical properties of the $3d$ $O(2)$ universality class in bounded domains through Monte Carlo simulations of the clock model. We use an improved version of the latter, chosen to minimize finite-size corrections at criticality, with 8 orientations of the spins and in the presence of vacancies. The domain chosen for the simulations is the slab configuration with fixed spins at the boundaries. We obtain the universal critical magnetization profile and two-point correlations, which favorably compare with the predictions of the critical geometry approach based on the Yamabe equation. The main result is that the correlations, once the dimensionful contributions are factored out with the critical magnetization profile, are shown to only depend on the distance between the points computed using a metric found solving the fractional Yamabe equation. The quantitative comparison with the corresponding results for the Ising model at criticality is shown and discussed. Moreover, from the magnetization profiles the critical exponent $η$ is extracted and found to be in reasonable agreement with up-to-date results.

Indeed, in the first year of the phd program a tool to store and retrieve the CMS condition data in the CMS databases has been developed.  A web monitor tool has been also deployed to trace and check the correctness of the transactions. Instead, in the second and third year of the phd program the decay of the $Z$ boson in two muons has been analyzed.

description: The origin of life occupies a very important place in the study of the evolution. Its liminal location between life and non-life poses special challenges to researchers who study this subject. Current approaches in studying the origin and evolution of early life are reductive: they either reduce the domain of non-life to the domain of life or vice versa. This contribution seeks to provide a perspective that would avoid reductionism of any kind. Its goal is to outline a frame that would include both domains and their respective evolutions as its particular cases. The study examines the main theoretical perspectives on the origin and evolution of early life and provides a constructive critique of these perspectives. An objective view require viewing an object or a phenomenon from all available points of view. The goal of this contribution is not to prove the current perspectives wrong and to deny their achievements. It seeks to provide an angle that would be sufficiently wide and would allow synthesizing current perspectives for a comprehensive and objective interpretation of the origin end evolution of early life. In other words, it seeks to outline a frame for an objective view that will help understand life's place within the universe.

description: Long non-coding RNA prostate cancer associated transcript-1 ncRNA (lncRNA-PCAT-1) plays an important role in the progression of prostate cancer. The present investigation was aimed to evaluate the potential roles of the lncRNA-PCAT-1 gene expression changes in esophageal squamous cell carcinoma (ESCC) between Iranian population. In the case-control investigation, we have analyzed a total of 150 fresh tissue samples, compromising of 75 cancerous tissues and 75 adjacent normal tissues from patients with ESCC. We used quantitative Real-time polymerase chain reaction (qRT-PCR) to evaluate the lncRNA-PCAT-1 gene expression levels in ESCC patients and correlation between the lncRNA-PCAT-1 expression changes and clinical characteristics. Our findings showed that the lncRNA-PCAT-1 gene was up-regulated in cancerous tissues compared with the adjacent non-cancerous tissues (p=0.0016). In addition, the results revealed a significant correlation between up-regulating of lncRNA-PCAT-1 and hot liquid drinking (p =0.017). These findings offer the potential roles of lncRNA-PCAT-1 in the pathogenesis of ESCC and may consider as a candidate prognostic biomarker for ESCC in an Iranian population.

Sviluppo di procedure numeriche per la simulazione del danno in strutture in composito.
Creators: name: Borrelli, Rosario

Year: 2011

description: La progettazione di strutture in materiale composito è ancora caratterizzata da un alto grado di conservativismo a causa delle difficoltà nel predire i meccanismi di danneggiamento tipici di questi materiali. Da qui la necessità di avere degli strumenti di simulazione in grado di predire il comportamento strutturale di componenti in composito, la loro resistenza al danno (damage resistance) e la loro tolleranza al danno (damage tolerance) sotto i carichi di esercizio. L’obiettivo principale del lavoro di tesi è stato proprio quello di mettere a punto delle procedure numeriche, basate essenzialmente sul Metodo agli Elementi Finiti (FEM), in grado di poter modellare l’innesco e l’evoluzione delle diverse tipologie di danneggiamento che caratterizzano le strutture in materiale composito. Per la messa a punto dei modelli predittivi si è fatto uso sia di codici di calcolo commerciali (LS-DYNA e ANSYS) sia di un codice open source (B2000++) nel quale è stato possibile implementare gli sviluppi presentati nella tesi. La tesi è sostanzialmente diviso in due parti:
•	Descrizione dello stato dell’arte rispetto alla problematica del danneggiamento e della relativa modellazione in strutture in composito (Capitolo 1 – Capitolo 3).
•	Presentazione degli sviluppi numerici e delle loro applicazioni (Capitolo 4 – Capitolo 6). In particolare, è proposto un modello di propagazione del danno da delaminazione in un pannello irrigidito (Capitolo 4), un modello di predizione del danneggiamento progressivo dovuto a impatti a bassa velocità (Capitolo 5) e un modello di predizione della resistenza residua (post-impatto) a compressione (Capitolo 6).
On analytic properties of entropy rate

description: Entropy rate is a real valued functional on the space of discrete random sources which lacks a closed formula even for subclasses of sources which have intuitive parameterizations. A good way to overcome this problem is to examine its analytic properties relative to some reasonable topology. A canonical choice of a topology is that of the norm of total variation as it immediately arises with the idea of a discrete random source as a probability measure on sequence space. It is shown that entropy rate is Lipschitzian relative to this topology, which, by well known facts, is close to differentiability. An application of this theorem leads to a simple and elementary proof of the existence of entropy rate of random sources with finite evolution dimension. This class of sources encompasses arbitrary hidden Markov sources and quantum random walks.

description: We present a quantitative analysis of the reversibility properties of classically chaotic quantum motion. We analyze the connection between reversibility and the rate at which a quantum state acquires a more and more complicated structure in its time evolution. This complexity is characterized by the number ${\cal M}(t)$ of harmonics of the (initially isotropic, i.e. ${\cal M}(0)=0$) Wigner function, which are generated during quantum evolution for the time $t$. We show that, in contrast to the classical exponential increase, this number can grow not faster than linearly and then relate this fact with the degree of reversibility of the quantum motion. To explore the reversibility we reverse the quantum evolution at some moment $T$ immediately after applying at this moment an instant perturbation governed by a strength parameter $ξ$. It follows that there exists a critical perturbation strength, $ξ_c\approx \sqrt{2}/{\cal M}(T)$, below which the initial state is well recovered, whereas reversibility disappears when $ξ\gtrsim ξ_c(T)$. In the classical limit the number of harmonics proliferates exponentially with time and the motion becomes practically irreversible. The above results are illustrated in the example of the kicked quartic oscillator model.

description: В статье рассмотрены упоминания в эфиопском синаксаре египетского города Никиу, известного, в том числе, тем, что его епископ Иоанн был автором «Хроники», описывающей события от сотворения мира до середины VII в. В эфиопском синаксаре название города, о котором до нас дошло немногое, встречается более десяти раз в дни памяти различных раннехристианских святых и мучеников в шести месяцах. Количество упоминаний города, несмотря на искажения в написании, свидетельствует о том, что эфиопы имели представление о городе Никиу как одном из христианских городов Египта.
description: The article is dealing with the mentions of the Egyptian city of Nikiu in the Ethiopian Synaxarium. This city is known by the fact that its bishop John was the author of the Chronicle reflecting the events from the Сreation until the mid-7th century AD. In the Ethiopian Synaxarium the name of the city of whom little is known is mentioned more than ten times in six months on the feast days of early Cristian saints and martyrs. The number of mentions of the city, despite the distortion in spelling, indicates that the Ethiopians had knowledge of the city of Nikiu as one of the Christian cities of Egypt.

description: Trigeminal neuralgia (TN) and orofacial pain (OFP) patients frequently refer to dentists. It is often confused with odontogenic pain and dental procedures are performed. In this study, the authors aimed to reveal the knowledge and experience of dentists about TN. This is a cross-sectional study that includes dentists who participate in volunteering via an online questionnaire. The questionnaire form contains demographic data, TN treatment, and diagnosis consisting of 18 questions. The data of 229 dentists were examined. Almost 82% of the participants reportedly knew the diagnostic criteria of TN and 61.6% reported that they had previously referred patients with TN. The most frequently confused diagnosis was odontogenic pains (45.9%). TN diagnostic criteria should be included more often in the education of dentists. Thus, it is possible to prevent unnecessary dental procedures. There is a need to increase knowledge on this subject with further studies involving dental students.

description: By generalizing and extending some of the earlier results derived by Manin and Merkulov, a twistor description is given of four-dimensional N-extended (gauged) self-dual supergravity with and without cosmological constant. Starting from the category of (4|4N)-dimensional complex superconformal supermanifolds, the categories of (4|2N)-dimensional complex quaternionic, quaternionic Kaehler and hyper-Kaehler right-chiral supermanifolds are introduced and discussed. We then present a detailed twistor description of these types of supermanifolds. In particular, we construct supertwistor spaces associated with complex quaternionic right-chiral supermanifolds, and explain what additional supertwistor data allows for giving those supermanifolds a hyper-Kaehler structure. In this way, we obtain a supersymmetric generalization of Penrose's nonlinear graviton construction. We furthermore give an alternative formulation in terms of a supersymmetric extension of LeBrun's Einstein bundle. This allows us to include the cases with nonvanishing cosmological constant. We also discuss the bundle of local supertwistors and address certain implications thereof. Finally, we comment on a real version of the theory related to Euclidean signature.
