description: Στόχος αυτής της μελέτης είναι να εξετάσει την περίπτωση της αναδιάρθρωσης του Ελληνικού δημόσιου χρέους και να εντοπίσει τις επιπτώσεις αυτής, στο εγχώριο τραπεζικό σύστημα, και όχι μόνο. Η μελέτη προσπαθεί να αναδείξει τους πιο αναμενόμενους τρόπους – μεθόδους αναδιάρθρωσης του χρέους και τα προβλήματα που θα προκαλέσει η καθεμιά από αυτές στα τραπεζικά ιδρύματα, ενώ παράλληλα πραγματοποιείται σύγκριση και με περιπτώσεις άλλων χωρών που προχώρησαν σε κάποιου είδους αναδιαπραγμάτευση του χρέους τους. Με αυτό το στόχο αντλήθηκαν σημαντικές πληροφορίες τόσο από βιβλιογραφικές αναφορές, δημοσιεύσεις και διαδικτυακές πηγές από το εξωτερικό, όσο και από το εσωτερικό. Το κύριο συμπέρασμα της εργασίας είναι πως κάθε μορφή αναδιάρθρωσης θα προκαλέσει μεγάλες δυσκολίες από πλευράς ρευστότητας στις Ελληνικές τράπεζες , ενώ δεν αποκλείεται ο κίνδυνος μετάδοσης του προβλήματος (Domino Effect) και σε άλλα κράτη που διατηρούν Ομόλογα Ελληνικού Δημοσίου.
description: The aim of this study is to examine the case of a Greek public debt restructuring and identify its impact on domestic banking system and beyond. The study tries to highlight the most expected ways - methods of debt restructuring and the problems would be caused each of them to the banks, while a comparison with other countries, which have moved to some kind of renegotiation of their debt, is made. For this purpose, important information was drawn from bibliographic reports, publications, web sources from abroad and from the Greek market. The main conclusion of this paper is that any form of restructuring would cause great difficulties in terms of liquidity to Greek banks, while it is not ruled out the risk of transmission of evil to other states that maintain Greek Government Bonds.

description: We present a study of the paramagnetic metallic and insulating phases of vanadium sesquioxide by means of the $N$th order muffin-tin orbital implementation of density functional theory combined with dynamical mean-field theory. The transition is shown to be driven by a correlation-induced enhancement of the crystal field splitting within the $t_{2g}$ manifold, which results in a suppression of the hybridization between the $a_{1g}$ and $e_g^π$ bands. We discuss the changes in the effective quasi-particle band structure caused by the correlations and the corresponding self-energies. At temperatures of about 400 K we find the $a_{1g}$ orbitals to display coherent quasi-particle behavior, while a large imaginary part of the self-energy and broad features in the spectral function indicate that the $e_g^π$ orbitals are still far above their coherence temperature. The local spectral functions are in excellent agreement with recent bulk sensitive photoemission data. Finally, we also make a prediction for angle-resolved photoemission experiments by calculating momentum-resolved spectral functions.

description: Στη παρούσα εργασία εξετάζεται πώς η εγκατάσταση των επιχειρήσεων σε διαφορετικές τοποθεσίες και η ύπαρξη του μεταφορικού κόστους επιδρούν στη συμπεριφορά των επιχειρήσεων που δρουν στην αγορά προϊόντων αλλά και στο μεταξύ τους ανταγωνισμό. Συγκεκριμένα αναπτύσσονται υποδείγματα χωρικού μονοπωλίου και ολιγοπωλίου κάτω από την ισχύ διαφορετικών υποθέσεων σχετικά με την τιμολογιακή πολιτική που εφαρμόζουν οι επιχειρήσεις και τη ζήτηση για το παραγόμενο αγαθό. Επιπρόσθετα δεδομένου ότι το υψηλό κόστος μεταφοράς αναδεικνύεται ως κύρια αιτία για τη μη αποτελεσματική λειτουργία των αγορών ενισχύοντας τη μονοπωλιακή δύναμη των επιχειρήσεων, επιχειρείται ο περιορισμός του στο πλαίσιο των πρωτότυπων υποδειγμάτων χωρικού ολιγοπωλίου με φορολογία. Τα χαμηλότερα επίπεδα του κόστους μεταφοράς επιτυγχάνονται μέσω της πραγματοποίησης επενδύσεων σε υποδομές μεταφορών χρηματοδοτούμενες μέσω του φορολογικού μηχανισμού σε αντιστοιχία με την εργασία των Suzuki και Sexton (2005). Συγκεκριμένα προσδιορίζεται η άριστη επιλογή επενδύσεων τόσο στη περίπτωση του αμιγούς δυοπωλίου όσο και στη περίπτωση του μικτού δυοπωλίου με συνεταιρισμό. Ενώ ο περιορισμός του μεταφορικού κόστους οδηγεί σε ισοδύναμα θετικά αποτελέσματα σε όρους ευημερίας και στις δύο μορφές αγοράς, φαίνεται πως στη περίπτωση του μικτού δυοπωλίου απαιτεί τη πραγματοποίηση χαμηλότερου όγκου επενδύσεων γεγονός που αποδίδεται στο μεγαλύτερο βαθμό ανταγωνιστικότητας που χαρακτηρίζει την αγορά εξαιτίας της δράσης του συνεταιρισμού.
description: The present study examines how the establishment of firms in different locations and the existence of transportation cost affect the behavior of firms operating in the product market and the competition between them. Models of spatial monopoly and oligopoly are developed under different assumptions on the pricing policy implemented by firms and the demand for manufactured goods. Additionally since the high transportation cost is emerging as a main reason for the inefficient function of markets by enhancing the monopoly power of firms, its restriction is attempted through the original models of spatial oligopoly with taxation. The lower transportation cost is achieved through investments in transportation infrastructure funded by the tax mechanism following the work of Suzuki and Sexton (2005). Specifically the best investment option is determined in both the case of pure duopoly and the case of mixed duopoly with a cooperative. While the reduction in transportation cost leads to equal positive results in terms of prosperity in both forms of market, it seems that in the case of mixed duopoly it requires making a lower level of investment which is attributed to the greater degree of competitiveness that characterizes the market due to the action of the cooperative.
A Review of the Properties of Nb3Sn and Their Variation with A15 Composition, Morphology and Strain State

description: This article gives an overview of the available literature on simplified, well defined (quasi-)homogeneous laboratory samples. After more than 50 years of research on superconductivity in Nb3Sn, a significant amount of results are available, but these are scattered over a multitude of publications. Two reviews exist on the basic properties of A15 materials in general, but no specific review for Nb3Sn is available. This article is intended to provide such an overview. It starts with a basic description of the Niobium-Tin intermetallic. After this it maps the influence of Sn content on the the electron-phonon interaction strength and on the field-temperature phase boundary. The literature on the influence of Cu, Ti and Ta additions will then be briefly summarized. This is followed by a review on the effects of grain size and strain. The article is concluded with a summary of the main results.

description: We present a mesoscopic model, based on the Boltzmann Equation, for the interaction between a solid wall and a non-ideal fluid. We present an analytic derivation of the contact angle in terms of the surface tension between the liquid-gas, the liquid-solid and the gas-solid phases. We study the dependency of the contact angle on the two free parameters of the model, which determine the interaction between the fluid and the boundaries, i.e. the equivalent of the wall density and of the wall-fluid potential in Molecular Dynamics studies. We compare the analytical results obtained in the hydrodynamical limit for the density profile and for the surface tension expression with the numerical simulations. We compare also our two-phase approach with some exact results for a pure hydrodynamical incompressible fluid based on Navier-Stokes equations with boundary conditions made up of alternating slip and no-slip strips. Finally, we show how to overcome some theoretical limitations connected with a discretized Boltzmann scheme and we discuss the equivalence between the surface tension defined in terms of the mechanical equilibrium and in terms of the Maxwell construction.

description: Με την παρούσα μεταπτυχιακή εργασία επιχειρήσαμε τη μελέτη του έργου ενός σπουδαίου επιστολογράφου των αρχών του 5ου αιώνα, του Ισίδωρου Πηλουσιώτη. Η εργασία αποτελείται από δύο μέρη˙ το πρώτο από αυτά περιλαμβάνει βιογραφικά και εργογραφικά στοιχεία του μοναχού Ισίδωρου. Οι 2.000 και πλέον επιστολές του αποδεικνύεται ότι συνθέτουν το σύνολο σχεδόν των πληροφοριών που αφορούν το βίο του, ενώ όσον αφορά το έργο του παραθέτουμε ορισμένες γενικές διαπιστώσεις. Στο δεύτερο μέρος, με την υποδιαίρεση σε δύο κεφάλαια, προσεγγίζουμε αναλυτικότερα το επιστολογραφικό του έργο. Στο κεφάλαιο 1 εντοπίζουμε τα δέκα σημαντικότερα θέματα, όπως προκύπτουν από το περιεχόμενο των επιστολών του και ειδικότερα την ιεροσύνη, το μοναχισμό και την ασκητική ζωή, την αρετή, την έμπρακτη διδασκαλία, τις διαπροσωπικές σχέσεις, το τρίπτυχο παρθενία – γάμος – πορνεία, τον πόλεμο και την ειρήνη, τα δεινά γαστριμαργία – μέθη – φιλαργυρία, τις αιρέσεις και τη διαδοχή παρούσα ζωή – κρίση – μέλλουσα ζωή. Στο κεφάλαιο 2 αναλύουμε ως προς τη δομή, τη μορφή και το περιεχόμενο τις επιστολές εκείνες που αφορούν το Πάθος και την Ανάσταση του Χριστού. Ειδικότερα, διακρίνονται σε εκείνες που αναφέρονται άμεσα και αποκλειστικά στις ημέρες του μαρτυρικού Πάθους, σε άλλες στις οποίες γίνονται ευκρινώς νύξεις σε πρόσωπα ή γεγονότα του Πάθους και της Ανάστασης και τέλος σε αυτές που εστιάζουν στο θεολογικό νόημα αυτών.
description: This thesis attempted to research the work of a great epistolographer of the early 5th century, Isidore Pilousioti. The work consists of two parts ˙ the first of these includes biographical information and list of works of the monk Isidore. The 2,000 and more letters show that they compose nearly all of the information on his life while on his work we present some general findings. In the second part, with the division into two chapters, we approach in detail his correspondence work. In chapter 1 we identify the ten most important issues, derived from the contents of his letters and in particular the clergy, the monastic and ascetic life, virtue, practical teaching, interpersonal relations, the triangle Virginity - marriage - prostitution, war and peace, the plight of gluttony - drunkenness - avarice, heresies and succession of this life - present - future life. In chapter 2 we analyze the structure, format and content of these letters on the Passion and Resurrection of Christ. In particular, they are divided into those that refer directly and exclusively to the days of the martyred Passion, in others where clearly allusions to persons or events of the Passion and Resurrection are made, and finally those that focus on the theological meaning of these.

description: The dissertation aimed (a) to examine selected consonants and consonantal clusters of Greek produced by adults’ learners of Greek as a second language (b) to evaluate the effectiveness of teaching intervention related to these segmental aspects within a communicative framework of teaching. The methodology included the contrastive analysis of the phonetic systems of Greek and of eight other languages spoken by the participants of this study, the preparation of a common pronunciation difficulties table, the analysis of questionnaires, the recording of segmental production before and after the teaching intervention, the teaching of pronunciation of the Greek consonants and consonantal clusters and the impressionistic analysis of segmental production before and after the intervention. The results showed that the explicit teaching of segmental elements in a communicative framework can be effective and approximate or achieve native-like production.
Hydrodynamic Theory for Reverse Brazil Nut Segregation and the Non-monotonic Ascension Dynamics

description: Based on the Boltzmann-Enskog kinetic theory, we develop a hydrodynamic theory for the well known (reverse) Brazil nut segregation in a vibro-fluidized granular mixture. Using an analogy with standard fluid mechanics, we have recently suggested a novel mechanism of segregation in granular mixtures based on a {\it competition between buoyancy and geometric forces}: the Archimedean buoyancy force, a pseudo-thermal buoyancy force due to the difference between the energies of two granular species, and two geometric forces, one compressive and the other-one tensile in nature, due to the size-difference. For a mixture of perfectly hard-particles with elastic collisions, the pseudo-thermal buoyancy force is zero but the intruder has to overcome the net compressive geometric force to rise. For this case, the geometric force competes with the standard Archimedean buoyancy force to yield a threshold density-ratio, $R_{ρ1}=ρ_l/ρ_s < 1$, above which the {\it lighter intruder sinks}, thereby signalling the {\it onset} of the {\it reverse buoyancy} effect. For a mixture of dissipative particles, the non-zero pseudo-thermal buoyancy force gives rise to another threshold density-ratio, $R_{ρ2}$ ($> R_{ρ1}$), above which the intruder rises again. Focussing on the {\it tracer} limit of intruders in a dense binary mixture, we find that the rise-time of the intruder could vary {\it non-monotonically} with the density-ratio. For a given size-ratio, there is a threshold density-ratio for the intruder at which it takes the maximum time to rise, and above(/below) which it rises faster, implying that {\it the heavier (and larger) the intruder, the faster it ascends}. Our theory offers a unified description for the (reverse) Brazil-nut segregation and the non-monotonic ascension dynamics of Brazil-nuts.

Aesthetic violence : the victimisation of women in the Quebec novel
Creators: name: Tilley, Jane Lucinda
Publisher: name: University of British Columbia
Year: 2009

description: The latent (androcentric) eroticism of rape has been exploited in Western culture, from mythology through to a contemporary entertainment industry founded on a cultural predilection for the representation of violence against women. In literature the figure of Woman as Victim has evolved according to shifting fashions and (male) desires until, in contemporary avant-garde writings, themes of sexual violence perform an intrinsic role in sophisticated textual praxis, Woman’s body becoming the playground for male artistic expression and textual experimentation. These themes are encoded in particular ways in Québec literature, where for many years the saintly Mother-figure served as both valorising icon and sacrificial victim of the conservative, messianic refuge values adopted following colonisation. The tacit matricide of the ideological literature is replaced, however, in the textually and linguistically subversive novels of the “quiet revolutionary” period by more explicit patterns of violence. Here, in place of quietly fading Mothers, female characters die screaming, victims of overt, sexual abuse at the hands of their male counterparts. Now frequently presented as voracious, oppressive and castrating, Woman must be destroyed if the “emasculated”, colonised male is to be liberated and become a “Man” once again. The relationship between colonisation and (sexual) violence is explicitly addressed in three novels of the period. Victor-Levy Beaulieu’s Un rêve québécois offers a model for the study of this connection, as the “shattering” of the text is reflected in the frenzy of frustration and sadistic (fantasised) violence directed at the unsympathetic, provocative wife of a colonised protagonist. Hubert Aquin’s L’Antiphonaire expands on the textual/sexual parallel, eroding the distinction between the body of the female protagonist/narrator and “her” text, as both are subject to repeated “violations”. Both novels subvert “realist” conceptualisations of time, identity, order etc., but rely on the continued and graphic victimisation of Woman to convey both a political and an aesthetic message. Marie-Claire Blais’s Une saison dans la vie d’Emmanuel, subverts the roman de la terre, exposing its ideology as the perpetuation of a cycle of implicit violence and victimisation, in which the ostensibly powerful and valorising Mother is the primary victim.

In particular, we focus on the recent determinations of the AGN luminosity function in the hard X-ray band at z~0 which constitutes the most stringent observational test for our models. Indeed, while we find an acceptable agreement between the model bolometric luminosity function and the data at 1

description: Τhe topic of this thesis is the impact of stimuli at consumption environment. Particularly it refers at those given at retail stores of clothes, especially at a period of an economic downturn. The theoretical analysis of this paper focuses at visual, sound stimuli and at smells a plethora of which can a customer easily understand at retail clothing stores. The kernel of the research has been is the term of atmospherics as it has been introduced and extensively researched through years in conjunction with theories analyzing the customer’s psychology and attitude. For the need of the research qualitative methods have been implemented in order to collect and analyze information related to the effect that those stimuli can have at a customer. Its pursuit is to find out how the consumer behavior is affected (positively or negatively) by those stimuli. Also is taken into serious consideration the fact that research is applied at a period of an economic downturn, a phenomenon which is widely acknowledged to deteriorate any kind of economic transactions and all those related to them.

description: The guided modes of sub-wavelength diameter air-clad optical fibers exhibit a pronounced evanescent field. The absorption of particles on the fiber surface is therefore readily detected via the fiber transmission. We show that the resulting absorption for a given surface coverage can be orders of magnitude higher than for conventional surface spectroscopy. As a demonstration, we present measurements on sub-monolayers of 3,4,9,10-perylene-tetracarboxylic dianhydride (PTCDA) molecules at ambient conditions, revealing the agglomeration dynamics on a second to minutes timescale.

description: Photoluminesce (PL) spectroscopy offers excellent methods for mapping the PL decay on the nanosecond time scale. However, capturing maps of emission dynamics on the microsecond time scale can be highly time-consuming. We present a new approach to fluorescence lifetime imaging FLIM, which combines the concept of random temporal speckles excitation (RATS) with the concept of a single-pixel camera based on spatial speckles. The spatio-temporal speckle pattern makes it possible to map PL dynamics with unmatched simplicity. Moreover, the method can acquire all data necessary to map PL decays in the microsecond timescale within minutes. We present proof of principle measurements for two samples and compare the reconstructed decays to the non-imaging measurements. Finally, we discuss the effect of the preprocessing routine and other factors on the reconstruction noise level. The presented method is suitable for lifetime imaging processes in several samples, including charge carrier dynamics in perovskites or monitoring solid-state luminophores with a long lifetime of PL.

description: Σκοπός της παρούσας εργασίας είναι η έρευνα των εν χρήσει σχολικών βιβλίων της Ιστορίας του Λυκείου από την οπτική του φύλου. Συγκεκριμένα, μελετήθηκε ο τρόπος που αναπαρίσταται το γυναικείο φύλο στους διάφορους τομείς της δημόσιας σφαίρας και της ιδιωτικής ζωής. Προκύπτει ότι η παρουσία της γυναίκας είναι ποσοτικά και ποιοτικά περιορισμένη, ενώ έντονος είναι ο διαχωρισμός των φύλων που ταυτίζει το αντρικό φύλο με τη δημόσια ζωή και τοποθετεί τη γυναίκα σχεδόν αποκλειστικά στον ιδιωτικό χώρο. Μελετώντας τη γλώσσα του βιβλίου προκύπτει πλήθος στερεοτύπων εις βάρος της γυναίκας, δίνοντας την εικόνα ενός σχεδόν αποκλειστικά «αντρικού» κόσμου. Ακόμη, η παρουσία της γυναίκας στην Ιστορία περιορίζεται στο περικείμενο και ειδικά στην εικονογραφία, ενώ συνήθως εμφανίζεται, σε αντίθεση με τον άντρα, σε διακοσμητικό ή παθητικό ρόλο και όχι σε ενεργό ή δυναμικό.
description: The purpose of this study is the research of history textbooks of high school from a gender perspective and specifically the presentation of the female sex in the various sectors of public sphere and private life. What comes out from the research is that women’s presence is quantitatively and qualitatively limited. It also exists an intense segregation that identifies the male sex in public life and places women almost exclusively in private sphere. Studying the book’s language come out many stereotypes against women and the image of an almost exclusively male world. Moreover, the presence of women in history textbooks exists mostly in contexts and iconography, and often appears, in contrast to men, in ornamental or passive role rather than active or potential.

Intracellular calcium regulation in the intact endothelial cells from rabbit aortic or pulmonic valves
Creators: name: Li, Li
Publisher: name: University of British Columbia

description: Intracellular Ca²⁺ signal and nitric oxide (NO) release from the intact endothelial cells of rabbit aortic or pulmonic valves were measured by digital imaging microscopy and NO microsensor, respectively. Vasoactive agents such as agonists, Ca²⁺ ionophore triggered an increase of cytoplasmic free calcium concentration ([Ca²⁺]j) and correspondent increase of NO release. Inhibitors of endoplasmic reticulum (ER) Ca²⁺ ATPase induced a [Ca²⁺]j. increase. SK&F 96365, a receptor-operated cation channel (ROC) blocker, and 2-nitro-4- carboxyphenyl-N, N-diphenyl-carbamate (NCDC), a postulated phospholipase C inhibitor and a ROC blocker, greatly reduce the agonist ATP induced sustained [Ca²⁺]j increase, but not the ER CA²⁺ ATPase inhibitor CPA induced [Ca²⁺]j increase. N2,i a Ca²⁺ entry blocker, blocked both the ATP- and CPA- induced [Ca²⁺]j increases. Divalent cation entry measured as Mn²⁺ quenching of fura-2 fluorescence was inhibited by Ni²⁺ but enhanced by ATP. This enhancement was abolished by pretreatment with NCDC or SK&F 96365. In contrast, the rate of Mn²⁺ quenching was unaffected by CPA. These results demonstrate that ATP stimulates a divalent cation influx through ROC, but interruption of ER Ca²⁺ accumulation does not signal an increased Ca²⁺ entry from the estracellular space. These results can be best explained by a “Superficial Buffer Barrier” (SBB) hypothesis where inhibition of Ca²⁺ uptake into the ER disrupts the Ca²⁺ buffer barrier function of ER, thus increasing the effectiveness of the Ca²⁺ leak in raising [Ca²⁺]j. A voltage gated Ca²⁺ channel (VGC) blocker, diltiazem, did not affect the ATP induced sustained [Ca²⁺]j increase. Depolarization of endothelial cells did not affect the resting [Ca²⁺]j, but blocked the ATP-induced sustained [Ca²⁺]j increase. These results indicate the absence of VGC in intact endothelial cells. Decreasing the Na gradient through either receptor stimulation (agonist), Na⁺,K⁺ pump inhibition (ouabain), Na⁺ ionophore (monensin) or by reversing Na⁺ gradient through Na⁺ substitution all increased [Ca²⁺]j,a implying the presence of a Na⁺ -Ca²⁺ exchange as a mechanism for Ca²⁺ entry on the plasmalemma of intact endothelium. This Ca²⁺ entry component is enhanced when [Na⁺]j is elevated.
Near-infrared spectra of Seyfert galaxies and line production mechanisms

description: New observations are reported of J-band spectra (1.04micron -- 1.4 micron) of three Seyfert 2 galaxies, Mkn 34, Mkn 78 and NGC 5929. In each case the spectral range includes the near-infrared lines of [FeII], [PII], HeI and Pa beta. Each Seyfert galaxy has a known radio jet, and we investigate the infrared line ratios of the nuclear and extended regions of each galaxy compared to the radio structure. In Mkn 34 there is a clear indication of an extranuclear region, probably coincident with a shock induced by the radio jet, in which [FeII] is considerably enhanced, although the nuclear emission is almost certainly the result of photoionization by the continuum of the active nucleus. Similar effects in extranuclear regions are seen in the other objects, in the case of Mkn 78 confirming recent studies by Ramos Almeida et al. A possible detection of extranuclear [PII] emission suggests, if real, that photoionization by the active nucleus is the dominant line excitation mechanism over the whole source, including the regions coincident with the radio jet.

description: This article provides the unconditional security of a semi quantum key distribution (SQKD) protocol based on 3-dimensional quantum states. By deriving a lower bound for the key rate, in the asymptotic scenario, as a function of the quantum channel's noise, we find that this protocol has improved secret key rate with much more tolerance for noise compared to the previous 2-dimensional SQKD protocol. Our results highlight that, similar to the fully quantum key distribution protocol, increasing the dimension of the system can increase the noise tolerance in the semi-quantum key distribution, as well.

description: Spatiotemporal traffic data imputation is of great significance in intelligent transportation systems and data-driven decision-making processes. To perform efficient learning and accurate reconstruction from partially observed traffic data, we assert the importance of characterizing both global and local trends in time series. In the literature, substantial works have demonstrated the effectiveness of utilizing the low-rank property of traffic data by matrix/tensor completion models. In this study, we first introduce a Laplacian kernel to temporal regularization for characterizing local trends in traffic time series, which can be formulated as a circular convolution. Then, we develop a low-rank Laplacian convolutional representation (LCR) model by putting the circulant matrix nuclear norm and the Laplacian kernelized temporal regularization together, which is proved to meet a unified framework that has a fast Fourier transform (FFT) solution in log-linear time complexity. Through extensive experiments on several traffic datasets, we demonstrate the superiority of LCR over several baseline models for imputing traffic time series of various time series behaviors (e.g., data noises and strong/weak periodicity) and reconstructing sparse speed fields of vehicular traffic flow. The proposed LCR model is also an efficient solution to large-scale traffic data imputation over the existing imputation models.

description: The modeling of many phenomena in various fields such as mathematics, physics, chemistry, engineering, biology, and astronomy is done by the nonlinear partial differential equations (PDE). The hyperbolic telegraph equation is one of them, where it describes the vibrations of structures (e.g., buildings, beams, and machines) and are the basis for fundamental equations of atomic physics. There are several analytical and numerical methods are used to solve the telegraph equation. An analytical solution considers framing the problem in a well-understood form and calculating the exact resolution. It also helps to understand the answers to the problem in terms of accuracy and convergence. These analytic methods have limitations with accuracy and convergence. Therefore, a novel analytic approximate method is proposed to deal with constraints in this paper. This method uses the Taylors' series in its derivation. The proposed method has used for solving the second-order, hyperbolic equation (Telegraph equation) with the initial condition. Three examples have presented to check the effectiveness, accuracy, and convergence of the method. The solutions of the proposed method also compared with those obtained by the Adomian decomposition method (ADM), and the Homotopy analysis method (HAM). The technique is easy to implement and produces accurate results. In particular, these results display that the proposed method is efficient and better than the other methods in terms of accuracy and convergence.

description: We show that a general linear transformation from one single photon qudit to another, the dimension of which can be either equal or unequal to that of the first one, can be implemented by linear optics. As an application of the scheme we elaborate a method to deterministically realize any finite-element Positive Operator Value Measure (POVM) on single photon signals, which is also generalizable to any quantum system in principle.

description: We discuss what ground states for generic interactions look like. We note that a recent result, due to Morris, implies that the behaviour of ground-state measures for generic interactions is similar to that of generic measures. In particular, it follows from his observation that they have singular spectrum and that they are weak mixing, but not mixing.

Flux Superpotential in Heterotic M-theory

description: We derive the most general flux-induced superpotential for N=1 M-theory compactifications on seven-dimensional manifolds with SU(3) structure. Imposing the appropriate boundary conditions, this result applies for heterotic M-theory. It is crucial for the latter to consider SU(3) and not G_2 group structure on the seven-dimensional internal space. For a particular background that differs from CY(3) x S^1/Z_2 only by warp factors, we investigate the flux-generated scalar potential as a function of the orbifold length. We find a positive cosmological constant minimum, however at an undesirably large value of this length. Hence the flux superpotential alone is not enough to stabilize the orbifold length at a de Sitter vacuum. But it does modify substantially the interplay between the previously studied non-perturbative effects, possibly reducing the significance of open membrane instantons while underlining the importance of gaugino condensation.

Unmasking of Novel Conic Modes in Electrically Stressed Perfectly Conducting Liquids

description: Liquid metal ion sources (LMIS) are widely used in applications ranging from local ion implantation in semiconductors, to focused ion beam systems for milling and nanolithography, to space micropropulsion devices being developed by NASA. Above a critically large field strength, an electrically stressed liquid metal develops one or more cuspidal protrusions which undergo accelerated conic tip sharpening with runaway field self-enhancement. Zubarev (2001) first predicted from an inviscid model that the electric stresses at the liquid apex undergo self-similar divergent growth in finite time. The inviscid assumption is appropriate to liquid metals since the viscous boundary layer extends only a few tens of nanometers from the moving interface. In this work, we examine in more depth a two-parameter family of far-field self-similar solutions incorporating inertial, electrical and capillary effects, which to leading order describe electric and velocity potential fields corresponding to a rapidly accelerating \textit{dynamic} Taylor cone. These far field solutions are incorporated self-consistently into boundary integral simulations which reveal the entire liquid shape in the near field. By invoking time reversal symmetry inherent to inviscid flow, we unmask an entire family of novel self-similar conic modes exhibiting features such as inertial recoil, tip bulging from accelerated advance and tip counter-current flow as well as multiple interface stagnation points. These dynamic configurations help explain for the first time the origin of decades old experimental observations that have reported phenomena such as tip oscillation, pulsation and breakup during operation. The various liquid tip shapes accessible to such systems should help correct persistent misconceptions of pre- and post-emission behavior in LMIS systems and related technologies.
