Borges, Dante e l'ambiguo tempo dell'arte
Creators: name: Fresko, Susanna
Publisher: name: Università degli Studi di Milano
Year: 2008

description: È frequente in Borges il riferimento a Dante come a uno degli scrittori fondamentali per la creazione della propria poetica. I suoi Saggi danteschi e, in particolare, Il falso problema di Ugolino, consentono di rintracciare alcuni degli aspetti più pregnanti del legame che Borges stabilisce tra sé e lo scrittore toscano e di fare luce su alcuni dei principi chiave che guidano la poetica borgesiana. In particolare, l’episodio di Ugolino e, più precisamente, il verso (poscia, più che ’l dolor, poté ’l digiuno), in cui Dante trasmette l’eterna oscillante immagine di Ugolino [che] divora e non divora gli amati cadaveri, costituisce per Borges una delle massime espressioni di un principio estetico fondamentale per la propria poetica: la capacità di esprimere i fatti tramite allusioni – evitando quindi di limitarne le possibili infinite biforcazioni – piuttosto che attraverso la mera esposizione circostanziata.

description: An efficient approach to the evaluation of effective elastic properties of carbon-carbon plain weave textile composites using the Mori-Tanaka method is presented. The method proves its potential even if applied to real material systems with various types of imperfections including the non-uniform waviness of the fiber-tow paths, both along its longitudinal direction and through the laminate thickness. Influence of the remaining geometrical parameters is accounted for by optimal calibration of the shape of the equivalent ellipsoidal inclusion. An application of the method to a particular sample of the carbon-carbon composite laminate demonstrates not only its applicability but also its efficiency particularly when compared to finite element simulations.

description: In this thesis, we present the results of investigating and the description of a new Markov Process, the Markov Mixture Process. The Markov Mixture Process aims to research and valuate credit rating of the firms thought all the world. We assume that each firm evolving according to one of the two Markov Chains of the Mixture Model. The two Markov Chains differ only in their implied migration speed, specifically in the rates with which they exist the states. In the first Chapter, some basic concepts and financial definitions, which are useful for the understanding of the theoretical part of this study, are given. In the second Chapter, we make an extensive reference and analysis of the Credit Risk and the Credit Rating Process of the firms. In the third Chapter, we present the Model which is going to be investigated and initially we make a sensitivity analysis. Consequently, we looking at the prediction in Credit Rating and we discuss probabilistic implications of the Markov Mixture, in special cases. Finally, we present the results of the Markov Mixture Model in a given application.
Destini che si incrociano

Publisher: name: Università degli Studi di Milano
Year: 2008

description: Destini che si incrociano: quello di Borges con quello di altri pionieri del modernismo in letteratura, come T.S.Eliot e P.Valéry. Un senso del moderno opposto e complementare a quello del romanticismo e dello psicologismo. Lucidità del pensiero e della tradizione che il soggettivismo sfrenato uccide in una confusa dialettica: proposito di creare un'estetica che sradichi ";l'eccezionale supremazia che oggigiorno usa attribuirsi all'io";. Si scopre così il legame tra Borges e lo gnosticismo, inteso come cristianesimo tragico che si pone agli albori del medioevo. Il netto dualismo di anima e corpo, l'assoluta trascendenza del divino, la lateralità dell'io, rappresentano il nucleo di quella che può definirsi la tragedia della modernità. Ma grazie alla mediazione del pensiero medievale non è una tragicità psicologica o distruttiva ma ricerca di una tradizione. Nella metafora del labirinto, emblema dei destini che si incrociano e luogo privilegiato in cui il soggetto prova l'angoscia della scelta (per cui imboccare l'uscita significa privilegiare una via a scapito di tutte le altre), si consuma la tragedia dell'io che scopre la consapevolezza dei propri limiti: ";essere una cosa è, inesorabilmente, non essere tutte le altre cose";.

G-domain prediction across the diversity of G protein families.
Creators: name: Rashmi, Richa
Publisher: name: Zenodo
Year: 2022

description: Guanine nucleotide-binding proteins are characterized by a structurally and mechanistically conserved GTP-binding domain, indispensable for binding GTP. The G domain comprises five adjacent consensus motifs called G boxes, which are separated by amino acid spacers of different lengths. Several G proteins, discovered over time, are characterized by diverse functions and sequences. This sequence diversity is also observed in the G box motifs (specifically the G5 box) as well as the inter-G box spacer length. The Spacers and Mismatch Algorithm (SMA) introduced in this study, can predict G-domains in a given G protein sequence, based on user-specified constraints for approximate G-box patterns and inter-box gaps in each G protein family. The SMA parameters can be customized as more G proteins are discovered and characterized structurally. Family-specific G box motifs including the less characterized G5 motif as well as G domain boundaries were predicted with higher precision. Overall, our analysis suggests the possible classification of G protein families based on family-specific G box sequences and lengths of inter-G box spacers.

description: Borges pronuncia giudizi molto severi su Agostino, considerato soprattutto come il pensatore della grazia e della predestinazione. Il pensiero agostiniano viene irrigidito in formule che ne fanno il campione di un preteso realismo medievale. Ma Borges è più vicino di quanto non creda ad Agostino che in realtà sa perfettamente che un senso alla vita dell’uomo viene non dalla impossibile conquista della felicità, ma dalla sua incessante ricerca.

The renormalized jellium model for spherical and cylindrical colloids

description: Starting from a mean-field description for a dispersion of highly charged spherical or (parallel) rod-like colloids, we introduce the simplification of a homogeneous background to include the contribution of other polyions to the static field created by a tagged polyion. The charge of this background is self-consistently renormalized to coincide with the polyion effective charge, the latter quantity thereby exhibiting a non-trivial density dependence, which directly enters into the equation of state through a simple analytical expression. The good agreement observed between the pressure calculated using the renormalized jellium and Monte Carlo simulations confirms the relevance of the {renormalized} jellium model for theoretical and experimental purposes and provides an alternative to the Poisson-Boltzmann cell model since it is free of some of the intrinsic limitations of this approach.
The energy expended on pulp fibres during low consistency refining
Creators: name: Martinez, Mark
Publisher: name: University of British Columbia
Year: 2009

description: Refining is a process in which the physical structure of the papermaking fibre is modified by repeated strain. While there is extensive literature on the changes in fibre morphology, there is little on the nature and magnitude of the forces which impose the strain. The objective of this dissertation was to estimate the force and energy expended on papermaking fibres in pulp refining. Both hydrodynamic and mechanical forces were considered. In the first half of the dissertation, a model is formulated to consider the hydrodynamic force acting on a single fibre trapped and transported on a moving bar edge. Equations were developed to predict the force as a function of fibre properties such as stiffness, length, and diameter, and fluid variables such as velocity and fluid viscosity. From this, the energy expended was estimated to vary within the range 10⁻¹² J to 10⁻¹¹ J for the cases studied. In the second half of the dissertation, theoretical and experimental estimates of the mechanical force acting on fibre flocs were developed. It was found that substantial force on fibres could only be imposed when the floc was compressed to near its zero void volume. Upon further compression of the floc, force was found to increase linearly with degree of compression. The theoretical estimates were found to agree reasonably well with the experimental measurements. The energy expenditure per fibre associated with these forces was found to be about 10⁻⁵ J. This compares favorably with estimates reported in the literature The energy associated with the mechanical force was approximately 6-7 orders of magnitude greater than that associated with the hydrodynamic force. This suggests that the latter contributes little to the refining action in pulp.

description: In un universo interpretato come sogno da decifrare, la metafisica è lo strumento, secondo Borges, con cui l’uomo tenta di rendere coerente questo sogno. Il pensiero di Eriugena è particolarmente affascinante per Borges, in quanto accetta la sfida della veritigine: un Dio che dal nulla della sua indeterminatezza dà luogo al mondo, dispiegandosi negli archetipi che popolano il sogno dell’universo. Una fantastica metafisica che allontana dall’uomo lo sgomento per la condanna alla propria individualità.

description: We embed the flipped SU(5) models into the SO(10) models. After the SO(10) gauge symmetry is broken down to the flipped SU(5) \times U(1)_X gauge symmetry, we can split the five/one-plets and ten-plets in the spinor \mathbf{16} and \mathbf{\bar{16}} Higgs fields via the stable sliding singlet mechanism. As in the flipped SU(5) models, these ten-plet Higgs fields can break the flipped SU(5) gauge symmetry down to the Standard Model gauge symmetry. The doublet-triplet splitting problem can be solved naturally by the missing partner mechanism, and the Higgsino-exchange mediated proton decay can be suppressed elegantly. Moreover, we show that there exists one pair of the light Higgs doublets for the electroweak gauge symmetry breaking. Because there exist two pairs of additional vector-like particles with similar intermediate-scale masses, the SU(5) and U(1)_X gauge couplings can be unified at the GUT scale which is reasonably (about one or two orders) higher than the SU(2)_L \times SU(3)_C unification scale. Furthermore, we briefly discuss the simplest SO(10) model with flipped SU(5) embedding, and point out that it can not work without fine-tuning.

I labirinti: il dramma del percorso

Publisher: name: Università degli Studi di Milano
Year: 2008

description: Il labirinto è un argomento ricorrente negli scritti di Borges, ed in particolar modo l’interesse dello scrittore argentino è rivolto al racconto del mito cretese, giunto ai nostri giorni attraverso l’elaborazione antica e medievale.

Nel corso del Medioevo l’elaborazione del mito attribuì grande importanza, soprattutto da un punto di vista metaforico, al fatto che la complessità del labirinto fosse solo apparente: il labirinto veniva concepito come un tracciato monoviario, ma ugualmente veniva descritto come un luogo nel quale, fino all’inevitabile momento del raggiungimento del centro, si aveva l’impressione di potersi perdere.

Le situazioni labirintiche borgesiane risultano similmente impostate, dal momento che sempre si raggiunge la meta (il centro del labirinto), ma solo dopo aver superato innumerevoli difficoltà, che inizialmente apparivano insormontabili.

description: This study used the Theories of Reasoned Action (TRA) and Planned Behaviour (TPB) in order to examine and predict pupils’ intention to con¬tinue to study in a Greek school of London. Eighty eight pupils completed self-administered questionnaires designed to measure the direct compo¬nents of the two theories in May 2004. Two hierarchical regression analyses were used to determine the relative contributions of attitude toward the behaviour, subjective norm and perceived behavioural control. The results showed that both the TRA and TPB in general are useful theories for pre¬dieting and exploring the factors that influence pupils’ intention. Attitude toward the behaviour was the best predictor of intention, followed by sub¬jective norm. The perceived behavioural control component in TPB had no effect on intention. Applicability of the TRA and TPB for pupils’ intention to continue to study in Greek schools of London and the implications for future research are discussed.

Improving cluster recovery with feature rescaling factors

Year: 2020

description: The data preprocessing stage is crucial in clustering. Features may describe entities using different scales. To rectify this, one usually applies feature normalisation aiming at rescaling features so that none of them overpowers the others in the objective function of the selected clustering algorithm. In this paper, we argue that the rescaling procedure should not treat all features identically. Instead, it should favour the features that are more meaningful for clustering. With this in mind, we introduce a feature rescaling method that takes into account the within-cluster degree of relevance of each feature. Our comprehensive simulation study, carried out on real and synthetic data, with and without noise features, clearly demonstrates that clustering methods that use the proposed data normalization strategy clearly outperform those that use traditional data normalization.

We have applied the high temperature expansion (HTE) method to isotropic case of their formula in a finite magnetic field and obtained coefficients for several short-range correlation functions. For example, we have succeeded to obtain the coefficients of the HTE of the 3rd neighbor correlation function $$ for zero magnetic field up to the order of 25. These results expand our previous results on the emptiness formation probability [Z.Tsuboi, M.Shiroishi, J. Phys.A: Math. Gen. 38(2005) L363; cond-mat/0502569] to more general correlation functions.

description: Purpose: Accurately classifying tissue margins during cancer surgeries is crucial for ensuring complete tumor removal. Rapid Evaporative Ionization Mass Spectrometry (REIMS), a tool for real-time intraoperative margin assessment, generates spectra that require machine learning models to support clinical decision-making. However, the scarcity of labeled data in surgical contexts presents a significant challenge. This study is the first to develop a foundation model tailored specifically for REIMS data, addressing this limitation and advancing real-time surgical margin assessment. Methods: We propose FACT, a Foundation model for Assessing Cancer Tissue margins. FACT is an adaptation of a foundation model originally designed for text-audio association, pretrained using our proposed supervised contrastive approach based on triplet loss. An ablation study is performed to compare our proposed model against other models and pretraining methods. Results: Our proposed model significantly improves the classification performance, achieving state-of-the-art performance with an AUROC of $82.4\% \pm 0.8$. The results demonstrate the advantage of our proposed pretraining method and selected backbone over the self-supervised and semi-supervised baselines and alternative models. Conclusion: Our findings demonstrate that foundation models, adapted and pretrained using our novel approach, can effectively classify REIMS data even with limited labeled examples. This highlights the viability of foundation models for enhancing real-time surgical margin assessment, particularly in data-scarce clinical environments.

description: This community service activity carried out at SMAN 2 Cibitung aims to provide knowledge and understanding of the Situation Based Learning learning model. To become a qualified and professional educator, teachers at the secondary school level are required to have a variety of skills and expertise to support teaching and learning activities in schools. Mathematics is one of the subjects that is frightening for students, most students think that mathematics is difficult. Teachers must be able to make this difficult assumption disappear, because if at school students don't like mathematics, then at the next higher level students will be increasingly afraid of mathematics lessons. That's why creative learning can be fun for students, teachers will be able to build students' liking for mathematics if they are able to provide fun learning. The Situation Based Learning learning model will help teachers in organizing creative and fun learning for students, so it is hoped that students will enjoy learning mathematics if teachers use this Situation Based Learning learning model.

description: A great amount of research is devoted to identifying and extracting the sentiment from texts. However, the classification accuracy remains quite low in comparison to other applications of natural language processing, such as topic extraction. We believe that a method capable of extracting and combining information from different text-levels, such as words and sentences, would be able to capture the sentiment of documents more accurately than existing techniques. In this thesis we propose three improved methods for cascaded sentiment analysis (semantic center, codebook and mixed-error autoencoders). Also, we introduce a new feature extraction approach for sentiment analysis, the multilevel cascaded sentiment analysis. We experimentally evaluate the proposed methods using two movie reviews datasets. Multilevel cascaded sentiment analysis was able to exceed the state-of-the art accuracy in one dataset by 1.1% and achieve the second best result in the other. We also provide statistically significant evidence that our method can lead to accuracy gains when combined with other document-level classifiers.

description: A new form of caching, namely application-level caching, has been recently employed in web applications to improve their performance and increase scalability. It consists of the insertion of caching logic into the application base code to temporarily store processed content in memory, and then decrease the response time of web requests by reusing this content. However, caching at this level demands knowledge of the domain and application specificities to achieve caching benefits, given that this information supports decisions such as what and when to cache content. Developers thus must manually manage the cache, possibly with the help of existing libraries and frameworks. Given the increasing popularity of application-level caching, we thus provide a survey of approaches proposed in this context. We provide a comprehensive introduction to web caching and application-level caching, and present state-of-the-art work on designing, implementing and managing application-level caching. Our focus is not only on static solutions but also approaches that adaptively adjust caching solutions to avoid the gradual performance decay that caching can suffer over time. This survey can be used as a start point for researchers and developers, who aim to improve application-level caching or need guidance in designing application-level caching solutions, possibly with humans out-of-the-loop.

Lic. degree in 1948 and the Fil. Dr. degree in 1950, all from the University of Stockholm. His Ph.D. thesis advisor was Harald Cramér. Professor Grenander is well known for pathbreaking research in a number of areas including pattern theory, computer vision, inference in stochastic processes, probabilities on algebraic structures and actuarial mathematics. He has published more than one dozen influential books, of which Statistical Analysis of Stationary Time Series (1957, coauthored with M. Rosenblatt), Probabilities on Algebraic Structures (1963; also in Russian) and Abstract Inference (1981b) are regarded as classics. His three-volume lecture notes, namely, Pattern Synthesis (vol. I, 1976), Pattern Analysis (vol. II, 1978) and Regular Structures (vol. III, 1981a; also in Russian) created and nurtured a brand new area of research. During 1951--1966, Professor Grenander's career path took him to the University of Chicago (1951--1952), the University of California--Berkeley (1952--1953), the University of Stockholm (1953--1957), Brown University (1957--1958) and the Institute for Insurance Mathematics and Mathematical Statistics (1958--1966) as its Professor and Director. From 1966 until his retirement he was L. Herbert Ballou University Professor at Brown University. Professor Grenander also held the position of Scientific Director (1971--1973) of the Swedish Institute of Applied Mathematics. He has earned many honors and awards, including Arhennius Fellow (1948), Fellow of the Institute of Mathematical Statistics (1953), Prize of the Nordic Actuaries (1961), Arnberger Prize of the Royal Swedish Academy of Science (1962), Member of the Royal Swedish Academy of Science (1965), Guggenheim Fellowship (1979) and Honorary Fellow of the Royal Statistical Society, London (1989). He has delivered numerous prestigious lectures, including the Rietz Lecture (1985), the Wald Lectures (1995) and the Mahalanobis Lecture (2004). Professor Grenander received an Honorary D.Sc. degree (1993) from the University of Chicago and is a Fellow of both the American Academy of Arts and Sciences (1995) and the National Academy of Sciences, U.S.A. (1998). Professor Grenander's career, life, passion and hobbies can all be summarized by one simple word: Mathematics.

description: The coherence of quantum Hall (QH) edges play the deciding factor in demonstrating an electron interferometer, which has potential to realize a topological qubit. A Graphene p-n junction (PNJ) with co-propagating spin and valley polarized QH edges is a promising platform for studying an electron interferometer. However, though a few experiments have been attempted for such PNJ via conductance measurements, the edge dynamics (coherent or incoherent) of QH edges at a PNJ, where either spin or valley symmetry or both are broken, remain unexplored. In this work, we have carried out the measurements of conductance together with shot noise, an ideal tool to unravel the dynamics, at low temperature (~ 10mK) in a dual graphite gated hexagonal boron nitride (hBN) encapsulated high mobility graphene device. The conductance data show that the symmetry broken QH edges at the PNJ follow spin selective equilibration. The shot noise results as a function of both p and n side filling factors reveal the unique dependence of the scattering mechanism with filling factors. Remarkably, the scattering is found to be fully tunable from incoherent to coherent regime with the increasing number of QH edges at the PNJ, shedding crucial insights into graphene based electron interferometer.

description: Σήμερα οι νέες Τεχνολογίες της Πληροφορίας και των Επικοινωνιών (ΤΠΕ) βρίσκουν εφαρμογή σε όλους τους τομείς της ανθρώπινης δραστηριότητας. Δύο από αυτούς τους τομείς είναι η Εκπαίδευση και η Δημοσιογραφία. Στην Εκπαιδευτική Διαδικασία, η ανάπτυξη του διαδικτύου και της ευρυζωνικότητας έδωσε μια νέα τροπή. Όλο και περισσότερα εκπαιδευτικά ιδρύματα, ιδιαίτερα της τριτοβάθμιας εκπαίδευσης, παρέχουν μαθήματα διαδικτυακά καταργώντας τους περιορισμούς του χώρου και του χρόνου. Η «τάξη» πλέον έγινε και "ηλεκτρονική". Στη Δημοσιογραφία δημιουργήθηκαν νέες προκλήσεις. Στην εποχή μας, εποχή του Big Data, καθημερινά δημιουργούνται 2,5 πεντάκις εκατομμύρια bytes (email, κοινωνικά δίκτυα, SMS κ.α.). Η νέα πρόκληση είναι οι «ιστορίες» που μπορούν να κρύβουν αυτά τα «ψυχρά» δεδομένα. Ιστορίες που μπορούν να βγουν μετά από κατάλληλη ανάλυση, επεξεργασία και αποτύπωση – οπτικοποίηση. Δηλαδή Δημοσιογραφία Δεδομένων. Η παρούσα μεταπτυχιακή διατριβή αποτελεί μια πρόταση διδασκαλίας για την οπτικοποίηση Δημοσιογραφικών Δεδομένων η οποία υλοποιείται στo διαδικτυακό Σύστημα Διαχείρισης Ηλεκτρονικής Τάξης ανοιχτού λογισμικού Moodle. Οι «μαθητές» στους οποίους απευθύνεται η πρόταση είναι φοιτητές/τριες Δημοσιογραφίας με προαπαιτούμενες βασικές γνώσεις και δεξιότητες στη χρήση ΗΥ και υπηρεσιών του διαδικτύου.
description: Today, new Information and Communication Technologies (ICT) are being applied to all fields of human activity. Two of these fields are Education and Journalism. In the Education Process, the development of the internet and broadband has introduced a new twist. Increasingly numerous educational establishments, especially those offering tertiary education, are providing lessons over the internet, thus doing away with the constraints of space and time. The “classroom” has come to be “electronic”. In Journalism, new challenges have arisen. In our times, the era of Big Data, on a daily basis 2.5 quintillion bytes are generated (email, social networks, SMS etc). The new challenge lies in the “stories” this “cold” data can hide. Stories which can emerge as a result of suitable analysis, processing and mapping – visualisation. In other words, Journalistic Data. The present postgraduate thesis constitutes a teaching proposal for the visualization of Journalistic Data which is effected using the online Electronic Classroom Management System open-software platform Moodle. The “students” at whom this proposal is aimed are students of Journalism with the prerequisite basic knowledge of and skills in using computers and internet services.

description: First, we review the Dirac operator folklore about basic analytic and geometrical properties of operators of Dirac type on compact manifolds with smooth boundary and on closed partitioned manifolds and show how these properties depend on the construction of a canonical invertible double and are related to the concept of the Calderon projection. Then we summarize a recent construction of a canonical invertible double for general first order elliptic differential operators over smooth compact manifolds with boundary. We derive a natural formula for the Calderon projection which yields a generalization of the famous Cobordism Theorem. We provide a list of assumptions to obtain a continuous variation of the Calderon projection under smooth variation of the coefficients. That yields various new spectral flow theorems. Finally, we sketch a research program for confining, respectively closing, the last re- maining gaps between the geometric Dirac operator type situation and the general linear elliptic case.

description: The purpose of this study was to examine the effect of a life skills pro¬gram to students’ personal and social responsibility and knowledge about responsible behaviors. Participants were 127 elementary students, who sep¬arated in experimental {n = 66) and control (n = 61) group. The program lasted 7 months and was based on the program “Skills for elementary school children” (TACADE, 1990). The results showed significant improvement in experimental group students’ personal and social responsibility and their knowledge about responsible behaviors. In conclusion, the life skills pro¬gram was effective as students referred higher levels of personal and social responsibility and higher levels of knowledge about responsible behaviors after the program’s implementation.

description: Σκοπός της παρούσας διπλωματικής εργασίας είναι η μελέτη της πράξης του βιασμού στις ένοπλες συγκρούσεις και η αντιμετώπιση του από τα Διεθνή Ποινικά Δικαστήρια. Αρχικά εξετάζονται οι διεθνείς κανόνες που άμεσα ή έμμεσα απαγορεύουν το βιασμό στις διεθνείς ή εσωτερικές ένοπλες συγκρούσεις. Στη συνέχεια, αφού γίνεται μια αναφορά στη γενοκτονία ως διεθνές έγκλημα, στη Σύμβαση για τη Γενοκτονία του 1948, καθώς και στη δημιουργία και στους σκοπούς του Διεθνούς Ποινικού Δικαστηρίου της Ρουάντα, παρατίθεται αναλυτικά η υπόθεση Jean – Paul Akayesu. Στην υπόθεση αυτή το Διεθνές Δικαστήριο για τη Ρουάντα αναγνώρισε το έγκλημα του βιασμού ως γενοκτονία και παρουσιάστηκε για πρώτη φορά επίσημα ένας διεθνής ορισμός του εγκλήματος του βιασμού στις ένοπλες συγκρούσεις. Αναφέρεται επίσης η σύσταση του Διεθνούς Ποινικού Δικαστηρίου για την πρώην Γιουγκοσλαβία και αναπτύσσεται η μελέτη τριών πολύ σημαντικών αποφάσεων του (η υπόθεση Delalic (The “Celebici Camp” case), η υπόθεση Furundzija και η υπόθεση Kunarac et al), στις οποίες ο βιασμός αναγνωρίστηκε και ταυτίστηκε με το βασανιστήριο. Τέλος, σχολιάζεται η ίδρυση του Διεθνούς Ποινικού Δικαστηρίου και η αρμοδιότητα του καθώς και δύο υποθέσεις του (η υπόθεση Thomas Lubanga Dyilo και η υπόθεση Jean – Pierre Bemba) που αφορούν την παρούσα μελέτη.
description: The purpose of this thesis is the study of the act of rape in armed conflicts and the treatment of the International Criminal Tribunals. Initial focus is on international rules which directly or indirectly prohibit rape in international or internal armed conflicts. Then it is presented the genocide as a war crime, the UN Convection on Genocide of 1948, the creation and objectives of the International Criminal of Rwanda and set out analytical the case Jean – Paul Akayesu. In this case the International Tribunal of Rwanda recognized the crime of rape as genocide and first presented officially an international definition of the crime of rape in armed conflicts. Also mentioned the establishment of the International Criminal Tribunal for the former Yugoslavia and the study develops three very important decisions (The Delalic case (The “Celebici Camp” case), the Furundzija case and the Kunarac et al case), in which rape was recognized and identified as torture. Finally, commenting on the establishment of the International Criminal Court and the responsibility of, and two cases of (the Thomas Lubanga Dyilo case and the case Jean – Pierre Bemba) concerning the current study.

description: The consequences of the short range nature of the nucleon-nucleon interaction, which forces the spatial part of the nuclear wave function to be as symmetric as possible, on the pseudo-SU(3) scheme are examined through a study of the collective deformation parameters beta and gamma in the rare earth region. It turns out that beyond the middle of each harmonic oscillator shell possessing an SU(3) subalgebra, the highest weight irreducible representation (the hw irrep) of SU(3) has to be used, instead of the irrep with the highest eigenvalue of the second order Casimir operator of SU(3) (the hC irrep), while in the first half of each shell the two choices are identical. The choice of the hw irrep predicts a transition from prolate to oblate shapes just below the upper end of the rare earth region, between the neutron numbers N=114 and 116 in the W, Os, and Pt series of isotopes, in agreement with available experimental information, while the choice of the hC irrep leads to a prolate to oblate transition in the middle of the shell, which is not seen experimentally. The prolate over oblate dominance in the ground states of even-even nuclei is obtained as a by-product.
