description: Αντικείμενο της παρούσας διπλωματικής εργασίας είναι η νομική αντιμετώπιση των νόθων τέκνων στην Αθήνα των κλασικών χρόνων. Αρχικά επιχειρήθηκε η διερεύνηση της ιδιότητας ενός τέκνου ως γνήσιου ή νόθου και συνακόλουθα, η άμεση επιρροή που ασκούσε η ιδιότητα αυτή στην ένταξη του στην κοινωνική και πολιτική ζωή της πόλεως και στη συνέχεια εξετάστηκε η σύνδεσή της με την ιδιότητα του Αθηναίου πολίτη. Μετά από την θεματική και ορολογική οριοθέτηση, η ανάλυση δομήθηκε σε τρείς άξονες. Στο πρώτο μέρος αναλύονται οι προϋποθέσεις ή άλλως τα κριτήρια χαρακτηρισμού ενός τέκνου ως γνήσιου ή νόθου αντίστοιχα. Έπειτα, στο δεύτερο μέρος, παρουσιάζεται το νομικό καθεστώς που διείπε τις σχέσεις των γνησίων και νόθων τέκνων τόσο με την οικογένεια του πατέρα τους, στα πλαίσια του οικογενειακού και κληρονομικού δικαίου, όσο και με την πολιτεία. Στο τρίτο μέρος εξετάζονται οι περιπτώσεις εξομοίωσης νόθου τέκνου με γνήσιο τέκνο. Ενώ, με χωριστή ενότητα, η οποία αναφέρεται στο αρχαίο δράμα, επιχειρείται να διερευνηθούν οι συνισταμένες εκείνες που καθόριζαν την νομική και κοινωνική θέση των νόθων τέκνων. Τέλος, καταλήγουμε στα συμπεράσματα της παρούσης εργασίας και εκθέτουμε τα επιστημονικά ευρήματα για τη νομική αντιμετώπιση των νόθων τέκνων, η οποία εξαρτιόταν από την κοινωνική και πολιτική τους θέση, η οποία με τη σειρά της διέφερε ανάλογα προς την εποχή και την εκάστοτε μορφή του πολιτεύματος.
description: The objective of this dissertation is to explore the illegitimate children’s (or bastards’) legal status in classical Athens. The project begins within the historical framework of the attribution of a legitimate or illegitimate child and the influence that this attribution could have on the social and political integration of this kind of child followed by an examination on the extent that this attribution could be associated with the Citizenship in Athens. This thesis consists of three main parts. The first part is devoted to the main concepts and relative characteristics of a legitimate or illegitimate child. The second part of the thesis treats the legal framework governing the relationship not only between a legitimate or illegitimate child and its father's family, regarding family and succession law but also between a legitimate or illegitimate child and the Republic. The third part deals with an examination of a possible equalization of conditions between a legitimate or illegitimate child. There is an additional chapter, referred to the ancient Greek drama, which argues for the conditions of the rights and status of illegitimate children. The concluding part includes a summary of the main findings regarding the illegitimate children’s legal status depending on their social and political status, which was different in comparisons between times and political systems.

description: Certain CFTs with a global $U(1)$ symmetry become superfluids when coupled to a chemical potential. When this happens, a Goldstone effective field theory controls the spectrum and correlators of the lightest large charge operators. We show that in 3d, this EFT contains a single parity-violating 1-derivative term with quantized coefficient. This term forces the superfluid ground state to have vortices on the sphere, leading to a spectrum of large charge operators that is remarkably richer than in parity-invariant CFTs. We test our predictions in a weakly coupled Chern-Simons matter theory.

description: A variety of Yang-Baxter maps are obtained from integrable multi-field equations on quad-graphs. A systematic framework for investigating this connection relies on the symmetry groups of the equations. The method is applied to lattice equations introduced by Adler and Yamilov and which are related to the nonlinear superposition formulae for the Bäcklund transformations of the nonlinear Schrödinger system and specific ferromagnetic models.

description: In theories with a warped extra dimension, composite fermions, as e.g. the right-handed top quark, can be very strongly coupled to Kaluza-Klein (KK) fields. In particular, the KK gluons in the presence of such composite fields become very broad resonances, thus remarkably modifying their experimental signatures. We have computed the pole mass and the pole width of the KK gluon, triggered by its interaction with quarks, as well as the prediction for proton-proton cross-sections using the full propagator and compared it with that obtained from the usual Breit-Wigner approximation. We compare both approaches, along with the existing experimental data from ATLAS and CMS, for the $t\bar t$, $t\bar t W$, $t\bar t Z$, $t\bar t H$, and $t\bar t t\bar t$ channels. We have found differences between the two approaches of up to about 100%, highlighting that the effect of broad resonances can be dramatic on present, and mainly future, experimental searches. The channel $t\bar t t\bar t$ is particularly promising because the size of the cross-section signal is of the same order of magnitude as the Standard Model prediction, and future experimental analyses in this channel, especially for broad resonances, can shed light on the nature of possible physics beyond the Standard Model.

description: Power moments, modified moments, and optimized moments are powerful tools for solving microscopic models of macroscopic systems; however the expansion of the density of states as a continued fraction does not converge to the macroscopic limit point-wise in energy with increasing numbers of moments. In this work the moment problem is further constrained by minimal lifetimes or maximal breaking of time-reversal symmetry, to yield approximate densities of states with point-wise macroscopic limits. This is applied numerically to models with one and two finite bands with various singularities, as well as to a model with infinite band-width, and the results are compared with the maximum entropy approximation where possible.

description: Η κατηγοριοποίηση γραπτών κειμένων ως προς το συναίσθημα είναι μία διαδικασία που παράγει πληροφορία αξιοποιήσιμη και άμεσα εκμεταλλεύσιμη σε ένα ευρύ πεδίο τομέων. Μέχρι προσφάτως, η διεργασία αυτή εκτελούνταν από ανθρώπους. Με την πάροδο του χρόνου και την ραγδαία αύξηση της διαθέσιμης πληροφορίας, έγινε επιτακτικής φύσεως η αυτοματοποίηση αυτής της διαδικασίας με τεχνητά μέσα. Στο πλαίσιο αυτής της εργασίας εφαρμόζονται ευφυείς τεχνικές ανάλυσης συναισθήματος, χρησιμοποιώντας μεθόδους μηχανικής μάθησης και συγκεκριμένα deep learning. Πιο αναλυτικά, σχεδιάζονται αρχιτεκτονικές με χρήση feedforward και συνελικτικών νευρωνικών δικτύων σε πολλαπλά επίπεδα και με πολλές μορφές, αξιοποιώντας προεπεξεργασμένα δεδομένα που παράχθηκαν με διάφορες τεχνικές NLP. Αναλυτικότερα, πέρα από την τελική προσέγγιση, η οποία ήταν ένας συνδυασμός συνελικτικών νευρωνικών δικτύων (CNN) και άλλων ευφυών τεχνικών, διερευνήθηκε η εφαρμογή Recurrent νευρωνικών δικτύων (LSTM), καθώς και τεχνικών βελτιστοποίησής τους (Attention mechanism, Dropout και Noise layers). Το αποτέλεσμα της σχεδίασης συγκρίθηκε με την ολοκληρωμένη υπηρεσία κατηγοριοποίησης κειμένων που αναπτύσσει το Πανεπιστήμιο του Stanford, η οποία χρησιμοποιεί μια διαφορετική προσέγγιση στην επίλυση του εν λόγω προβλήματος.

description: Sentiment classiﬁcation of written text is a process that produces useful and exploitable information in a wide range of domains. Until recently, this process was carried out by humans. In the course of time, the rapid increase of available information, necessitate the automation of this process by artiﬁcial means. In this work, intelligent sentiment analysis techniques are being implemented, using machine learning and speciﬁcally deep learning methods. In particular, architectures are being designed using multi-level Convolutional Neural Networks (CNNs), utilizing preprocessed data generated by various NLP techniques. Furthermore, beyond the ﬁnal approach, which was a combination of CNNs and other intelligent techniques, the implementation of Recurrent Neural Networks (LSTMs) and optimization techniques (Attention mechanism, Dropout and Noise layers) were explored. The result of the design was compared to the integrated text classiﬁcation service developed by the University of Stanford, which uses a diﬀerent approach to solving this problem.

description: We construct simple unconstrained Lagrangian formulations for massless higher spin fields in flat space of arbitrary dimension and on anti de Sitter background. Starting from the triplet equations of Francia and Sagnotti, which describe a chain of spin modes, we introduce an auxiliary field and find appropriate gauge invariant constraints that single out the spin-s mode. The resulting quartet of fields, thus describing an irreducible representation of the Poincare group, is used to construct simple Lagrangian formulations, which are local, free from higher derivative terms and use equal number of auxiliary fields for an unconstrained description of any value of spin. Our method proves to be most efficient for an unconstrained description of massless higher spin fermions in anti de Sitter space. A relation of the minimal models with the universal BRST approach is discussed.

description: We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has strong contributions from second-order effects that have been neglected so far. We calculate the second-order piezoelectric tensors using density functional theory and obtain the piezoelectric field for [111]-oriented In$_x$Ga$_{1-x}$As quantum wells of realistic dimensions and concentration $x$. We find that the linear and the quadratic piezoelectric coefficients have the opposite effect on the field, and for large strains the quadratic terms even dominate. Thus, the piezoelectric field turns out to be a rare example of a physical quantity for which the first- and second-order contributions are of comparable magnitude.

A pricing model for forage in British Columbia
Creators: name: Haggard, Trenton John
Publisher: name: University of British Columbia
Year: 2009

description: The production of forage in British Columbia plays and integral role in sustaining livestock herds within the province. Forage is an important component in the daily feed requirements of horses, sheep, and cattle. Fluctuations in the availability of forage due to drought or bad weather conditions can impose considerable costs on farmers who raise livestock. Wide—spread drought conditions can significantly limit the availability of forage crops within certain regions, causing prices within those regions to become inflated. Under standard insurance in British Columbia, farmers are only insured against shortfalls in production; there is no compensation provided against increases in the price of forage. For those purchasing forage, a Wide—Spread Drought (WSD) insurance scheme would provide insurance against the price—risk associated with drastic weather conditions. However, since forage prices are required to operate such a policy and are non—observable, a mechanism is needed in order to estimate them. A regional spatial price—equilibrium model which relates regional prices to regional production is developed in this thesis. The model will eventually be used to predict prices and hence determine whether a particular region is eligible for a payout under the WSD insurance scheme. A key assumption behind the model is that according to the ‘Law of One Price’; prices are perfectly arbitraged. In a competitive setting, in which agents maximize individual welfare, total welfare is maximized and prices between regions will not differ by more than the transportation costs. This spatial price—equilibrium model is applied to British Columbia forage production. The regions incorporated in the study include the Peace River, Central Interior, Cariboo—Chilcotin, Thompson—Okanagan, and Kootenay Regions. The Lower Mainland/Fraser Valley and Vancouver Island are excluded as they do not typically fall under the forage crop insurance plan in British Columbia.

description: We present Spitzer-IRAC, NOAO 2.1meter-Flamingos, Keck-NIRC, and FCRAO-SEQUOIA observations of the massive star forming complex S254-S258, covering an area of 25x20 arc-minutes. Using a combination of the IRAC and NIR data, we identify and classify the young stellar objects (YSO) in the complex. We detect 510 sources with near or mid IR-excess, and we classify 87 Class I, and 165 Class II sources. The YSO are found in clusters surrounded by isolated YSO in a low-density distributed population. The ratio of clustered to total YSO is 0.8. We identify six new clusters in the complex. One of them, G192.63-00, is located around the ionizing star of the HII region S255. We hypothesize that the ionizing star of S255 was formed in this cluster. We also detect a southern component of the cluster in HII region S256. The cluster G192.54-0.15, located inside HII region S254 has a VLSR of 17 km/s with respect to the main cloud, and we conclude that it is located in the background of the complex. The structure of the molecular cloud is examined using 12CO and 13CO, as well as a near-IR extinction map. The main body of the molecular cloud has VLSR between 5 and 9 km/s. The arc-shaped structure of the molecular cloud, following the border of the HII regions, and the high column density in the border of the HII regions support the idea that the material has been swept up by the expansion of the HII regions.

Real-time wavelet-integrated corrosion detection system for casing pipes

Publisher: name: figshare
Year: 2021
Subjects: subject: 10399 Numerical and Computational Mathematics not elsewhere classified
subject: FOS: Mathematics

description: Corrosion occurs frequently at the interior or exterior of steelcasing pipes used in underground gas storage or oil fields. Itcauses not only production loss but also environmental pollution. Hence, corrosion monitoring and early detection of corrosion pits and wall thinning on casing pipes are considerably important to the gas and petroleum industry.
We introduce in this paper a new version of the direct current electromagnetic induction system which is capable of detecting small, isolated corrosion pits and holes on the casing wall. A sensor system based on the direct current electromagnetic induction instrument is coupled to an updated data acquisition system. Information represented by enormous data sensed by the downhole instruments is to be transmitted to the computer logging system on surface, and a wavelet data compression technique is incorporated. A complete internal/external circumferential survey of corrosion extent on casing pipes can be obtained. Unlike the conventional direct current induction instrument, this system provides all the measured flux leakage signals and eddy current signals, and hence a full signature logging response. It allows an accurate differentiation of the casing pipe hardware from corrosion, and much easier interpretation of corrosions on casing pipes.
To achieve the real time mode during the logging operation,
a VLSI integrated circuit realizing the wavelet transform hasbeen designed. Simulations have been conducted, and theintegrated circuit has been fabricated. The test results showthat the design is advantageous and the circuit performanceis satisfying.
Leveraging spectral analysis to elucidate membrane locking and unlocking in isogeometric finite element formulations of the curved Euler-Bernoulli beam

description: In this paper, we take a fresh look at using spectral analysis for assessing locking phenomena in finite element formulations. We propose to "measure" locking by comparing the difference between eigenvalue and mode error curves computed on coarse meshes with "asymptotic" error curves computed on "overkill" meshes, both plotted with respect to the normalized mode number. To demonstrate the intimate relation between membrane locking and spectral accuracy, we focus on the example of a circular ring discretized with isogeometric curved Euler-Bernoulli beam elements. We show that the transverse-displacement-dominating modes are locking-prone, while the circumferential-displacement-dominating modes are naturally locking-free. We use eigenvalue and mode errors to assess five isogeometric finite element formulations in terms of their locking-related efficiency: the displacement-based formulation with full and reduced integration and three locking-free formulations based on the B-bar, discrete strain gap and Hellinger-Reissner methods. Our study shows that spectral analysis uncovers locking-related effects across the spectrum of eigenvalues and eigenmodes, rigorously characterizing membrane locking in the displacement-based formulation and unlocking in the locking-free formulations.

description: In Late Victorian Gothic literature, the notion of the body is often discussed as an ambiguous construct demarcated by deep-seated social, cultural and moral codes that attach particular and firm connotations to it. Therefore, I am going to explore the medicalization of the deviant body and its portrayal in the ever-popular trope of the vampire in relation to the issues of gender and sexuality. Two primary literary texts are employed for this purpose, namely Joseph Sheridan Le Fanu’s Carmilla (1871) and Bram Stoker’s Dracula (1897). The aim of this dissertation is to showcase that the medicalization of the Late Victorian Gothic literature functioned as a quasi-scientific conduct book that furthered socio-sexual control during the late 1800s. Hence, I am going to examine the conditions that formed mental and sexual deviancy by laying particular emphasis on the orality of the vampiric figure, which shaped the didactic character of this genre elevating it to the position of a gendered morality tale.
description: Στην Ύστερη Βικτωριανή Γοτθική λογοτεχνία, η ιδέα του σώματος εξετάζεται συχνά ως μία διφορούμενη έννοια προσδιοριζόμενη από βαθιά ριζωμένους κοινωνικούς, πολιτισμικούς και ηθικούς κώδικες που τοποθετούν συγκεκριμένες και σταθερές ερμηνείες σε αυτήν. Επομένως, σκοπεύω να εξετάσω την ιατρικοποίηση του αποκλίνοντος σώματος και την απεικόνιση του στην δημοφιλή αλληγορία του βρικόλακα σε σχέση με τα θέματα του φύλλου και της σεξουαλικότητας. Δύο λογοτεχνικά κείμενα χρησιμοποιούνται για αυτόν τον σκοπό, πιο συγκεκριμένα η Καρμίλλα (1871) του Τζόσεφ Σέρινταν λε Φανού και ο Δράκουλας (1897) του Μπραμ Στόκερ. Ο στόχος της παρούσας διπλωματικής εργασίας είναι να παρουσιάσει ότι η ιατρικοποίηση της Ύστερης Βικτωριανής Γοτθικής λογοτεχνίας λειτούργησε ως ένας εν μέρει επιστημονικός οδηγός συμπεριφοράς που προώθησε τον κοινωνικό και σεξουαλικό έλεγχο στα τέλη του 1800. Επομένως, σκοπεύω να εξετάσω τις συνθήκες που διαμόρφωσαν την διανοητική και σεξουαλική αποκλίνουσα συμπεριφορά δίνοντας ιδιαίτερη έμφαση στην στοματικό χαρακτήρα της φιγούρας του βρικόλακα, που αναδιαμόρφωσε το διδακτικό χαρακτήρα του λογοτεχνικού είδους εξυψώνοντας το στην θέση μίας ιστορίας με ηθικό δίδαγμα βασιζόμενη στο φύλλο.

description: We introduce a toy model of the "rat race" in which individuals try to better themselves relative to the rest of the population. An individual is characterized by a real-valued fitness and each advances at a constant rate by an amount that depends on its standing in the population. The leader advances to remain ahead of its nearest neighbor, while all others advance by an amount that is set by the distance to the leader. A rich dynamics occurs as a function of the mean jump size of the trailing particles. For small jumps, the leader maintains its position, while for large jumps, there are long periods of stasis that are punctuated by episodes of explosive advancement and many lead changes. Intermediate to these two regimes, agents reach a common fitness and evolution grinds to a halt.

description: Σκοπός της μεταπτυχιακής εργασίας ήταν η μελέτη της αιγυπτιακής λατρείας και πιο συγκεκριμένα, των ιερών και της λατρείας του Άμμωνος Διός, όπως αυτή διαδόθηκε στον ελληνικό χώρο καθ΄ όλη τη διάρκεια των ιστορικών χρόνων. Η εστίαση αποκλειστικά στη λατρεία του Άμμωνος Διός οφείλεται κυρίως στο γεγονός ότι ήταν ο πρώτος εκ των Αιγυπτίων θεοτήτων που εγκαθίδρυσε την παρουσία του στο ελληνικό πάνθεον. Στο πρώτο μέρος της εργασίας αρχικά έγινε μία συνοπτική παρουσίαση των σχέσεων που δημιουργήθηκαν μεταξύ του ελληνικού και αιγυπτιακού κόσμου. Ακολουθεί μία αναφορά στη λατρεία του Άμμωνος στην Αίγυπτο, ενώ στη συνέχεια αναπτύχθηκε το θέμα της μετακίνησης της λατρείας στην όαση της Σίβα και έπειτα στην ελληνική αποικία της Κυρήνης. Στο δεύτερο μέρος και μετά από μία σύντομη περιγραφή σχετικά με τον τρόπο εξάπλωσης της λατρείας του Άμμωνος Διός στον κυρίως ελληνικό χώρο, εξετάστηκαν όλες οι έως σήμερα γνωστές μαρτυρίες που επιβεβαιώνουν το γεγονός. Στο τελευταίο κεφάλαιο παρουσιάστηκε αναλυτικά το ιερό του Άμμωνος Διός στην Άφυτιν της Χαλκιδικής. Τέλος, έγινε μία σύνοψη των σημαντικότερων σημείων της εργασίας και διατυπώθηκαν τα συμπεράσματα
description: The aim of this post-graduate dissertation was the study of the Egyptian cult and, precisely, the sanctuaries and worship dedicated to Ammon Zeus, since it spread to Greece throughout the course of the historic times. The exclusive focus on the cult of Ammon Zeus is due to the fact that he was one of the first Egyptian deities to secure a place in the Greek pantheon. In the first part of the dissertation, there was a brief cover on the relationship between Greeks and Egyptians. After that followed a report on the worship of Amun in Egypt, and then an analysis on the topic of how the worship started to gradually move to the oasis of Siwa and thereafter the Greek colony of Cyrene. In the second part, after a short description regarding the way that the cult of Ammon Zeus spread to the main part of Greece, there was an examination of all known to-date testimonies that confirm this event. In the last chapter, there was an analytical showcase of the Ammon Zeus sanctuary in Aphytis, Chalkidiki. It was followed by a synopsis of the most important points of the dissertation and the conclusions of this study

description: We compute the probability that intermediate mass black holes (IMBHs) capture companions due to dynamical interactions and become accreting sources, and explore the possibility that the accreting IMBHs would appear as ultra-luminous X-ray sources (ULXs). We focus on IMBHs originating from low-metallicity Population III stars. Two channels of IMBH formation are considered: from primordial halos in the framework of hierarchical clustering, and from non-mixed, zero-metallicity primeval gas in galactic discs. IMBHs can form binary systems due to tidal captures of single stars and exchange interactions with existing binary systems in galactic discs. We find that neither formation mechanism of the accreting IMBH binary is able to provide enough sources to explain the observed population of ULXs. Even at sub-ULX luminosity, the total number of accreting IMBHs with $L> 10^{36}$ erg s$^{-1}$ with dynamically captured companions is found to be $< 0.01$ per galaxy.

description: The stellar equilibrium and collapse, including mainly white dwarfs, neutron stars and supper massive stars, is an interplay between general relativistic effects and the equation of state of nuclear matter. We study the stability of Einstein's field equations for sphere of fluid, like neutron stars, by employing realistic equations of state of neutron star matter, describing the relation between pressure and density, in order to use the Chandrasekhar's criterion of stellar instability. We mainly focus on the critical point of transition from stable to unstable configuration. This point corresponds to the maximum neutron star mass configuration. We calculate, in each case, the resulting compactness parameter, β, and the corresponding effective adiabatic indices, averaged and critical. We found that it holds a model-independent relation between the critical point of transition from stable to unstable configuration and the compactness parameter. Accurate observational measurements of the upper bound of the neutron star mass and the corresponding radius, in connection with the present predictions, may help to impose constraints on the high density part of the neutron star equation of state.
description: Η αστρική ισορροπία και κατάρρευση, συμπεριλαμβανομένων κυρίως λευκών νάνων, αστέρων νετρονίων και αστέρων μεγάλης μάζας, είναι μία αλληλεπίδραση μεταξύ των επιδράσεων της γενικής σχετικότητας και της καταστατικής εξίσωσης της πυρηνικής ύλης. Μελετάμε την ευστάθεια των εξισώσεων πεδίου του Αϊνστάιν για μία σφαίρα ρευστού, όπως οι αστέρες νετρονίων, εφαρμόζοντας ρεαλιστικές καταστατικές εξισώσεις της ύλης των αστέρων νετρονίων, οι οποίες περιγράφουν τη σχέση μεταξύ πίεσης και πυκνότητας, έτσι ώστε να χρησιμοποιήσουμε το κριτήριο αστρικής αστάθειας του Chandrasekhar. Εστιάζουμε κυρίως στο κρίσιμο σημείο μετάβασης από ευσταθή σε ασταθή κατάσταση. Αυτό το σημείο αντιστοιχεί στην κατάσταση μέγιστης μάζας του αστέρα νετρονίων. Υπολογίζουμε, σε κάθε περίπτωση, την προκύπτουσα παράμετρο που δείχνει το πόσο συμπαγής είναι ένας αστέρας, β, και τους αντίστοιχους αδιαβατικούς δείκτες, μέσο και κρίσιμο. Διαπιστώσαμε ότι υπάρχει μια σχέση μεταξύ του κρίσιμου σημείου μετάβασης από την ευσταθή στην ασταθή κατάσταση και της παραμέτρου β, η οποία είναι ανεξάρτητη του μοντέλου. Ακριβείς μετρήσεις παρατήρησης του ανώτατου ορίου της μάζας αστέρων νετρονίων και της αντίστοιχης ακτίνας, σε σχέση με τις παρούσες προβλέψεις, μπορούν να συμβάλουν στην επιβολή περιορισμών στην περιοχή υψηλών πυκνοτήτων της καταστατικής εξίσωσης του αστέρα νετρονίων.

Static Ricci-flat 5-manifolds admitting the 2-sphere

description: We examine, in a purely geometrical way, static Ricci-flat 5-manifolds admitting the 2-sphere and an additional hypersurface-orthogonal Killing vector. These are widely studied in the literature, from different physical approaches, and known variously as the Kramer - Gross - Perry - Davidson - Owen solutions. The 2-fold infinity of cases that result are studied by way of new coordinates (which are in most cases global) and the cases likely to be of interest in any physical approach are distinguished on the basis of the nakedness and geometrical mass of their associated singularities. It is argued that the entire class of solutions has to be considered unstable about the exceptional solutions: the black string and soliton cases. Any physical theory which admits the non-exceptional solutions as the external vacuua of a collapsing object has to accept the possibility of collapse to zero volume leaving behind the weakest possible, albeit naked, geometrical singularities at the origin.Finally, it is pointed out that these types of solutions generalize, in a straightforward way, to higher dimensions.

description: We show how a sparticle spectrum characteristic of anomaly mediation can arise from a theory whose Lagrangian contains no explicit mass scale. The scale of supersymmetry breaking is governed by the gravitino mass, which is the vacuum expectation value of the F-term of the conformal compensator field, and the tachyonic slepton problem is resolved by the breaking of a U(1) gauge symmetry at a scale determined by dimensional transmutation.

The relationship of hardiness to work satisfaction among critical care nurses
Creators: name: John, Robin Lyn
Publisher: name: University of British Columbia
Year: 2009

description: The purpose of this study was to investigate the role that a stress-resistant characteristic, hardiness, might play in work satisfaction among critical care nurses. A descriptive correlational design was used to measure the relationship between hardiness and work satisfaction. A Demographic Information Form, the Personal Views Survey (measuring hardiness), and the Index of Work Satisfaction were completed by 109 full-time critical care staff nurses in three urban hospitals. The scores on the latter two instruments were correlated using Pearson's product-moment correlation. Correlation coefficients showed a weak relationship between hardiness and work satisfaction which strengthened when challenge, the functionally distinct part of hardiness, was removed. The relationship further strengthened when pay, a work satisfaction component which defied the normal distribution assumption, was eliminated from the work satisfaction score. Hardiness explained only 17.5% of the variance in work satisfaction indicating that more is involved in work satisfaction than possession of the appropriate personal characteristics. Future studies of the relationship between hardiness and work satisfaction should examine causality by including all the variables in the model (hardiness, working conditions, subjective stress, work satisfaction and work performance) in a longitudinal or path analysis design. Although the relationship between hardiness and work satisfaction has not yet been shown to be causal, increasing a sense of hardiness may improve work satisfaction among critical care nurses. Teaching them hardiness may improve retention and quality of care, and minimize grievances, absenteeism, and strikes. Other implications for nursing and recommendations for further research are presented.
Parallel Parsing Algorithms for Static Dictionary Compression

Subjects: subject: 80302 Computer System Architecture

description: The data compression based on dictionary techniques works by replacing phrases in the input string with indexes into some dictionary. The dictionary can be static or dynamic. In static dictionary compression, the dictionary contains a predetermined fixed set of entries. In dynamic dictionary compression, the dictionary changes its entries during compression. We present parallel algorithms for two parsing strategies for static dictionary compression. One is the optimal parsing strategy with dictionaries that have the prefix property, for which our algorithm requires O(L + log n) time and O(n) processors, where n is the number of symbols in the input string, and L is the maximum length of the dictionary entries, while previous results run in O(L + log n) time using O(n2) processors or in O(L + log2 n) time using O(n) processors. The other is the longest fragment first (LFF) parsing strategy, for which our algorithm requires O(L + log n) time and O(n log L) processors, while a previous result obtained an O(L log n) time performance on O(n/ log n) processors. For both strategies, we derive our parallel algorithms by modifying the on-line algorithms using a pointer doubling technique.
Impact of the mesoscale structure of a bipartite ecological interaction network on its robustness through a probabilistic modeling

description: The robustness of an ecological network quantifies the resilience of the ecosystem it represents to species loss. It corresponds to the proportion of species that are disconnected from the rest of the network when extinctions occur sequentially. Classically, the robustness is calculated for a given network, from the simulation of a large number of extinction sequences. The link between network structure and robustness remains an open question. Setting a joint probabilistic model on the network and the extinction sequences allows analysis of this relation. Bipartite stochastic block models have proven their ability to model bipartite networks e.g. plant-pollinator networks: species are divided into blocks and interaction probabilities are determined by the blocks of membership. Analytical expressions of the expectation and variance of robustness are obtained under this model, for different distributions of primary extinction sequences. The impact of the network structure on the robustness is analyzed through a set of properties and numerical illustrations. The analysis of a collection of bipartite ecological networks allows us to compare the empirical approach to our probabilistic approach, and illustrates the relevance of the latter when it comes to computing the robustness of a partially observed or incompletely sampled network.

description: Contradiction between Hawking's semi-classical arguments and string theory on the evaporation of black hole has been one of the most intriguing problems in fundamental physics. A final-state boundary condition inside the black hole was proposed by Horowitz and Maldacena to resolve this contradiction. We point out that original Hawking effect can be also regarded as a separate boundary condition at the event horizon for this scenario. Here, we found that the change of Hawking boundary condition may affect the information transfer from the initial collapsing matter to the outgoing Hawking radiation during evaporation process and as a result the evaporation process itself, significantly.
