description: In this paper, a decay vacuum model $\barρ_Λ=3σM_p^2H_0 H$ is revisited by detailed analysis of background evolution and perturbation equations. We show the imprints on CMB temperature and matter power spectrum from the effective coupling terms between dark sectors by comparing to the standard cosmological constant model and observational data points (WMAP7 and SDSS DR7). We find that the decay vacuum model can describe the expansion rate at late times as well as the standard cosmological constant model but it fails to simultaneously reproduce the observed CMB and matter power spectrum. Its generalization $\barρ_Λ=3M_p^2(ξ_1 H_0 H+ξ_2 H^2)$ is also discussed. Detailed analysis of the background evolution shows that the dimensionless parameter $ξ_{2}$ would be zero to avoid the unnatural 'fine tuning' and to keep the positivity of energy density of dark matter and dark energy in the early epoch.

description: Aliphatic polyesters are the most promising biodegradable plastics because of their high susceptibility to the attack of hydrolytic
 enzymes and of many microorganisms naturally occurring in the environment. Poly(butylene succinate-co-adipate) (PBSA) is a biobased semicrystalline copolymer of poly(butylene succinate) (PBS), with adipic acid as co-monomer. It is highly biodegradable
 because of its lower crystallinity and higher flexibility of polymer chains compared to PBS. In the present study, the biodegradability mechanism of PBSA was evaluated using cutinase from Humicola insolens, which is a commercial hydrolytic enzyme presenting both lipase and esterase features. The polyester degradation is based on weight loss measurements combined to other analyses (i.e., GPC, 1H NMR, and DSC) performed on the residual solids of PBSA films, in order to understand the molecular and chemical modifications induced at the surface and/or in the bulk of polymer materials over time. The results showed that the enzymatic degradation mechanism of cutinase proceed by degrading the polymer from the surface of the film. An exo-type cleaving action mode was proposed based on the identification of the oligomers and monomers released as degradation products.

Messages to the public : Krzysztof Wodiczko and Jenny Holzer vs. the Reagan revolution
Creators: name: Sorenson, Vanessa Nicole
Publisher: name: University of British Columbia
Year: 2010

description: In the week preceding the 1984 United States presidential election, Jenny Holzer and Krzysztof Wodiczko presented ephemeral works of art in public spaces in Manhattan that addressed the election and were highly critical of President Ronald Reagan. Previous considerations of Wodiczko’s AT&T projection, Holzer’s Sign on a Truck and the larger public art movement of that time have emphasized a post-structuralist interpretation, neglecting the applied political aspects in favour of their theoretical underpinnings. With a move towards the practical aspects of the works, this thesis examines the conditions that led to the presentation of these two works and considers what they can teach us about the larger practice of political public art during that period in New York. Chapter 1 considers the political, economic and artistic context of the United States—and New York in particular—in the early to mid 1980s. The Chapter 2 offers an analysis of Wodiczko’s AT&T projection, a night-time projection of the image of President Reagan’s French-cuffed hand onto the side of the AT&T Long Lines building, posed for a recognizable American ritual, the Pledge of Allegiance. Chapter 3 closely considers Sign on a Truck, for which Jenny Holzer deployed a giant screen, mounted on the side of an 18-wheeler truck, to display pre-recorded videos created by collaborating artists interspersed with “man-on-the-street” interviews commenting on the looming presidential election. By shedding the insightful yet constraining post-structural lens that has traditionally coloured the art historical understanding of these works, their essential educative aspects are revealed and a broader understanding is made possible, not only of these two artists and their respective projects, but also of the defense that was mounted by New York's public artists against the “Reagan Revolution.”

description: Language-based information flow methods offer a principled way to enforce strong security properties, but enforcing noninterference is too inflexible for realistic applications. Security-typed languages have therefore introduced declassification mechanisms for relaxing confidentiality policies, and endorsement mechanisms for relaxing integrity policies. However, a continuing challenge has been to define what security is guaranteed when such mechanisms are used. This paper presents a new semantic framework for expressing security policies for declassification and endorsement in a language-based setting. The key insight is that security can be characterized in terms of the influence that declassification and endorsement allow to the attacker. The new framework introduces two notions of security to describe the influence of the attacker. Attacker control defines what the attacker is able to learn from observable effects of this code; attacker impact captures the attacker's influence on trusted locations. This approach yields novel security conditions for checked endorsements and robust integrity. The framework is flexible enough to recover and to improve on the previously introduced notions of robustness and qualified robustness. Further, the new security conditions can be soundly enforced by a security type system. The applicability and enforcement of the new policies is illustrated through various examples, including data sanitization and authentication.
Parametric amplification and self-oscillation in a nanotube mechanical resonator

description: A hallmark of mechanical resonators made from a single nanotube is that the resonance frequency can be widely tuned. Here, we take advantage of this property to realize parametric amplification and self-oscillation. The gain of the parametric amplification can be as high as 18.2 dB and tends to saturate at high parametric pumping due to nonlinear damping. These measurements allow us to determine the coefficient of the linear damping force. The corresponding damping rate is lower than the one obtained from the lineshape of the resonance (without pumping), supporting the recently reported scenario that describes damping in nanotube resonators by a nonlinear force. The possibility to combine nanotube resonant mechanics and parametric amplification holds promise for future ultra-low force sensing experiments.

Dynamical friction in a gaseous medium with a large-scale magnetic field

description: The dynamical friction force experienced by a massive gravitating body moving through a gaseous medium is modified by sufficiently strong large-scale magnetic fields. Using linear perturbation theory, we calculate the structure of the wake generated by, and the gravitational drag force on, a body traveling in a straight-line trajectory in a uniformly magnetized medium. The functional form of the drag force as a function of the Mach number (V_0/c_s, where V_0 is the velocity of the body and c_s the sound speed) depends on the strength of the magnetic field and on the angle between the velocity of the perturber and the direction of the magnetic field. In particular, the peak value of the drag force is not near Mach number 1 for a perturber moving in a sufficiently magnetized medium. As a rule of thumb, we may state that for supersonic motion, magnetic fields act to suppress dynamical friction; for subsonic motion, magnetic fields tend to enhance dynamical friction. For perturbers moving along the magnetic field lines, the drag force at some subsonic Mach numbers may be stronger than it is at supersonic velocities. We also mention the relevance of our findings to black hole coalescence in galactic nuclei.

title: The role of social enterprise in the transition to a low carbon energy system
Creators: name: Hillman, J
Publisher: name: Liverpool John Moores University
Year: 2019

description: Socio-technical transitions have come to the forefront of academic debate on the challenges of developing a low-carbon economy. According to the transitions literature, addressing socio-ecological problems and underlying complexes of technologies and institutions requires novel approaches with a long-term orientation, as well as reflexive and adaptive policy design. Niche innovations play an important role in unearthing new solutions during the transition to a low-carbon energy system. In this context, the main aim of this investigation is to review the value of applying social enterprise in community owned energy schemes as a form of social innovation. This thesis reports on original research undertaken on the Role of Social Enterprise in the Transition to a Low Carbon Energy System. Through an in-depth case study and policy analysis, extensive stakeholder engagement and interrogation of the characteristics of social enterprises across a range of contexts, the potential of social enterprise to act as local level social innovation niche is investigated. The research conducted provides insight into the holistic nature of energy focused social enterprises and explores the common barriers faced such as raising finance, project development and managing key stakeholders. This investigation provides a business model perspective on the formulation of social enterprise within a socio-technical transitions conceptual framework. More broadly, the potential of social enterprises to act as ‘transitions engines’, by delivering a just community energy transition is investigated. The research has several important findings; 1) that social enterprises can increase democratisation in the energy system, 2) the premature withdrawal of protected space has hindered the growth of the community energy sector, and 3) the rapidly changing policy landscape has triggered innovation activity in the community energy sector. Social enterprises within a low carbon energy system are likely to remain at the niche level unless financially viable business models that can compete in the energy market can be identified and scaled-up.
Magnetic structure of noncentrosymmetric perovskites PbVO3 and BiCoO3

description: It is well known that if a crystal structure has no inversion symmetry, it may allow for Dzyaloshinskii-Moriya magnetic interactions, operating between different crystallographic unit cells, which in turn should lead to the formation of long-periodic spin-spiral structures. Such a behavior is anticipated for two simple perovskites PbVO3 and BiCoO3, crystallizing in the noncentrosymmetric tetragonal P4mm structure. Nevertheless, we argue that in reality PbVO3 and BiCoO3 should behave very differently. Due to the fundamental Kramers degeneracy for the odd-electron systems, PbVO3 has no single-ion anisotropy. Therefore, the ground state of PbVO3 will be indeed the spin spiral with the period of about one hundred unit cells. However, the even-electron BiCoO3 has a large single-ion anisotropy, which locks this system in the collinear easy-axis C-type antiferromagnetic ground state. Our theoretical analysis is based on the low-energy model, derived from the first-principles electronic structure calculations.

title: Dreiphasen-Wechselrichter mit schlankem Spannungszwischenkreis zum Einsatz in unsymmetrisch belasteten Niederspannungsnetzen
Creators: name: Holbein, Markus
Publisher: name: UNSPECIFIED
Year: 2020

description: Beim Anschluss von Ein- oder Zweiphasenlasten an das Dreiphasen-Wechselspannungsnetz kann es zu Spannungsunsymmetrien kommen, die den einwandfreien Betrieb bestimmter Geräte beeinflussen und die Übertragungsverluste vergrößern. Die Schieflastproblematik ist insbesondere in Niederspannungsnetzen mit geringer Kurzschlussleistung von Bedeutung, welche oftmals mit kleinen Vermaschungsgraden oder langen Netzausläufern in Verbin-dung steht. Aktuell führt das FNN eine entsprechende „Unsymmetrie-Studie“ durch [1], was vor dem Hintergrund einer sich ändernden Erzeuger- und Verbraucherstruktur auf die zu-nehmende Relevanz des Themenfeldes hindeutet. Wird das nach DIN EN 50160 auf 2 % festgelegte Verhältnis zwischen der Spannungs-Gegen- und Mitsystemkomponente überschritten, stehen einerseits klassische Maßnahmen in Form von Netzausbau und passiven Symmetrierschaltungen zur Verfügung. Anderseits sind auch aktive, leistungselektronische Lösungen denkbar, die im Rahmen der vorliegenden Arbeit theoretisch untersucht und auf Basis eines eigens entwickelten Dreiphasen-Vierleiter-Wechselrichters praktisch erprobt werden. Eine vollständige, d.h. stationär genaue Auslöschung der netzfrequenten Spannungs-Gegen- und ggf. der Nullsystemkomponente erfolgt am Netzanschlusspunkt des Wechselrichters ohne direkte Kenntnis der Lastströme basierend auf einer einfachen Spannungsmessung. Nach entsprechender Signalaufbereitung und unter Verwendung der vom Wechselrichter ermittelten Netzadmittanz, lassen sich die notwendigen, vom Wechselrichter aufzubringenden Kompensationsströme generieren. Durch Verkopplung der symmetrischen Strom- und Spannungsgrößen treten Pendelleistun-gen mit doppelter Netzgrundfrequenz auf, die auf den Spannungszwischenkreis des Wechselrichters einwirken. Statt hier zur Einhaltung eines kleinen Spannungsripples auf die Wirkung passiver Zwischenkreisvarianten zu setzen, kommt ein dediziertes aktives Filter zum Einsatz. Es ermöglicht unter Ausnutzung eines vergrößerten, vom Zwischenkreisniveau entkoppelten Spannungshubs den energetischen Nutzungsgrad der Speicherkapazität zu verbessern und so Elektrolyt- durch Folienkondensatoren zu substituieren. Mit der Maß-nahme lässt sich neben der zu erwartenden höheren Zuverlässigkeit das zugehörige Bauvo-lumen auf 53 % reduzieren. Eine optimierte Regelstrategie mit hoher Dynamik begrenzt transiente Abweichungen der Zwischenkreisspannung bei Aufschaltung der DC-Bemessungslast auf max. 7 % bzgl. des Nominalwertes. Somit ist unter Berücksichtigung der Stromgrenzen weiterhin ein Betrieb als aktiver Gleichrichter zur Speisung von Nieder-spannungs-Gleichstromnetzen oder –lasten möglich.

description: Solar-like oscillations have been observed by Kepler and CoRoT in several solar-type stars, thereby providing a way to probe the stars using asteroseismology. We provide the mode frequencies of the oscillations of various stars required to perform a comparison with those obtained from stellar modelling. We used a time series of nine months of data for each star. The 61 stars observed were categorised in three groups: simple, F-like and mixed-mode. The simple group includes stars for which the identification of the mode degree is obvious. The F-like group includes stars for which the identification of the degree is ambiguous. The mixed-mode group includes evolved stars for which the modes do not follow the asymptotic relation of low-degree frequencies. Following this categorisation, the power spectra of the 61 main sequence and subgiant stars were analysed using both maximum likelihood estimators and Bayesian estimators, providing individual mode characteristics such as frequencies, linewidths, and mode heights. We developed and describe a methodology for extracting a single set of mode frequencies from multiple sets derived by different methods and individual scientists. We report on how one can assess the quality of the fitted parameters using the likelihood ratio test and the posterior probabilities. We provide the mode frequencies of 61 stars (with their 1-sigma error bars), as well as their associated echelle diagrams.

description: Leakage channel fibers, designed to suppress higher-order modes, demonstrate resonant power loss at certain critical radii of curvature. Outside the resonance, the power recovers to the levels offset by the usual mechanism of bend-induced loss. Using C$^2$-imaging, we experimentally characterize this anomaly and identify the corresponding physical mechanism as the radiative decay of the fundamental mode mediated by the resonant coupling to a cladding mode.

description: We identify an abundant population of extreme emission line galaxies (EELGs) at redshift z~1.7 in the Cosmic Assembly Near-IR Deep Extragalactic Legacy Survey (CANDELS) imaging from Hubble Space Telescope/Wide Field Camera 3 (HST/WFC3). 69 EELG candidates are selected by the large contribution of exceptionally bright emission lines to their near-infrared broad-band magnitudes. Supported by spectroscopic confirmation of strong [OIII] emission lines -- with rest-frame equivalent widths ~1000Å-- in the four candidates that have HST/WFC3 grism observations, we conclude that these objects are galaxies with 10^8 Msol in stellar mass, undergoing an enormous starburst phase with M_*/(dM_*/dt) of only ~15 Myr. These bursts may cause outflows that are strong enough to produce cored dark matter profiles in low-mass galaxies. The individual star formation rates and the co-moving number density (3.7x10^-4 Mpc^-3) can produce in ~4 Gyr much of the stellar mass density that is presently contained in 10^8-10^9 Msol dwarf galaxies. Therefore, our observations provide a strong indication that many or even most of the stars in present-day dwarf galaxies formed in strong, short-lived bursts, mostly at z>1.

description: Sulfur isotope-amount ratios (generally reported as δ34/32S or δ33/32S) have been used for nutrition and migration studies of humans and animals in various bio-compartments for decades. Especially hair represents a promising chemical archive for sulfur.In contrast to total sulfur, the isotopic composition of the major sulfur-containing amino acids reveal more information about the nutritional status and living conditions of an individual, since they have different original sources and follow different metabolic pathways. Methionine and cysteine are incorporated into proteins (e.g. in hair). Methionine cannot be synthesized by the human and animal organism and therefore has to be supplied by the diet. Cysteine is synthesized by the body, but the process requires a steady supply of sulfur.For this reason, the development and optimization of a species-specific method to assess the isotopic composition of sulfur in these amino acids in hair is a prerequisite to gain more understanding about the underlying fundamental processes. Hence, the aim of this master thesis is to develop an analytical method, both to separate the amino acids from hair and to assess the sulfur isotopic composition in the collected fractions. The methodological approach included the development of a proper sample preparation to clean the hair and a suitable digestion method to obtain the intact amino acids derivatives methionine sulfone and cysteic acid from hair through oxidation and hydrolysis of methionine and cysteine. For separating and collecting fractions of the oxidized sulfur-containing amino acids, a procedure was developed and optimized using high-performance liquid chromatography (HPLC). Finally, sulfur isotope-amount ratios were recorded by multi-collector inductively coupled plasma mass spectrometry (MC ICP-MS).
Relation Strength-Aware Clustering of Heterogeneous Information Networks with Incomplete Attributes

description: With the rapid development of online social media, online shopping sites and cyber-physical systems, heterogeneous information networks have become increasingly popular and content-rich over time. In many cases, such networks contain multiple types of objects and links, as well as different kinds of attributes. The clustering of these objects can provide useful insights in many applications. However, the clustering of such networks can be challenging since (a) the attribute values of objects are often incomplete, which implies that an object may carry only partial attributes or even no attributes to correctly label itself; and (b) the links of different types may carry different kinds of semantic meanings, and it is a difficult task to determine the nature of their relative importance in helping the clustering for a given purpose. In this paper, we address these challenges by proposing a model-based clustering algorithm. We design a probabilistic model which clusters the objects of different types into a common hidden space, by using a user-specified set of attributes, as well as the links from different relations. The strengths of different types of links are automatically learned, and are determined by the given purpose of clustering. An iterative algorithm is designed for solving the clustering problem, in which the strengths of different types of links and the quality of clustering results mutually enhance each other. Our experimental results on real and synthetic data sets demonstrate the effectiveness and efficiency of the algorithm.

Art Historical and Provenance Research in a Case Study of Huangchao Liqi Tushi
Creators: name: Zhao, Haoyang
Publisher: name: Journal for Art Market Studies
Year: 2020

description: Using an illustrated album of the Qing im­perial court of the eighteenth century as a case study, the article explores the specific challenges presented for provenance re­search by this type of object, as well as the reciprocal benefits of interlinking research in provenance with that of traditional art history. The Huangchao Liqi Tushi, or the Illustrations of Imperial Ritual Parapher­nalia, is an illustrated encyclopedic album of Qing imperial regulations and codes. The album discussed here was potentially looted from the Qing imperial garden, the Yuanming yuan, in 1860 by Anglo-French troops. Today, seven public institutions across the world are known to hold pages of the coloured version of the HCLQTS. In Europe, the V&A, the National Museum of Scotland, the National Museum of Ireland, and the British Library all have incomplete sections of the HCLQTS in their collections. In North America, the Mactaggart Collec­tion of the University of Alberta Museums also holds an incomplete section. As re­search on this project is ongoing, a com­prehensive report on the album’s prove­nance will not yet be outlined. Instead, the author shares his experience on how disre­garded marks on the back of each page, together with the materials typically cate­gorised as art historical, provided essential support for provenance investigation in a case where limited records were available.

description: With the increasing popularity of herbomineral preparations in healthcare, a new proprietary herbomineral formulation was formulated with ashwagandha root extract and minerals viz. zinc, magnesium, and selenium. The aim of the study was to evaluate the immunomodulatory potential of Biofield Energy Healing (The Trivedi Effect®) on the herbomineral test formulation using mice splenocytes. The test formulation was divided into two parts. One part was the control without the Biofield Treatment. The other part was labelled the Biofield Treated sample, which received the Biofield Energy Healing Treatment remotely from twenty renowned Biofield Energy Healers. The splenocyte cells were exposed with the test formulation at ranges of 0.00001053 to 10.53 µg/mL for cell viability by MTT assay, with cell viability ranging from 77.50% to 176.52%. TNF-α was significantly inhibited by 15.88%, 15.28%, 12.30%, 12.60%, and 22.72% at 0.00001053, 0.001053, 0.1053, 1.053, and 10.53 µg/mL, respectively in the Biofield Treated test formulation compared to the vehicle control (VC). TNF-α was significantly reduced by 2.33% and 8.35% at 1.053 and 10.53 µg/mL, respectively compared to the untreated test formulation. IL-1β was significantly reduced by 30.81%, 27.36%, 23.92%, 18.40%, 11.27%, and 21.16% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, and 1.053 µg/mL, respectively in the Biofield Treated test formulation compared to the VC. IL-1β was significantly reduced by 48.63% (p≤0.001) and 15.28% at 0.00001053 and 0.0001053 µg/mL, respectively in the Biofield Treated test formulation compared to the untreated test formulation. MIP-1α expression was inhibited by the Biofield Treated test formulation and showed immunosuppressive activity at 0.01053, 0.1053, 1.053, and 10.53 µg/mL by 22.33%, 16.25%, 15.58%, and 21.83%, respectively compared to the VC. The Biofield Treated test formulation significantly reduced the MIP-1α expression by 13.27% and 15.67% (p0.05) at 0.01053 and 10.53 µg/mL, respectively compared to the untreated test formulation. The results showed the expression of IFN-γ was significantly reduced by 33.45%, 25.38%, 37.15%, 27.74%, 32.44%, 23.03%, and 44.21% at 0.00001053, 0.0001053, 0.001053, 0.01053, 0.1053, 1.053, and 10.53 µg/mL, respectively in the Biofield Treated test formulation compared to the VC. Further, the IFN-γ level was significantly decreased by 19.02% at 10.53 µg/mL in the Biofield Treated test formulation compared to the untreated test formulation. Overall, the results demonstrate that The Trivedi Effect® Biofield Energy Healing (TEBEH) significantly enhanced the anti-inflammatory and immunomodulatory properties of the treated formulation, and may also be useful in organ transplants, anti-aging, and stress management by improving overall health and quality of life.

description: We present a new 400 ks Chandra X-ray observation of the merging galaxy cluster Abell 2146. This deep observation reveals detailed structure associated with the major merger event including the Mach M=2.3+/-0.2 bow shock ahead of the dense, ram pressure stripped subcluster core and the first known example of an upstream shock in the ICM (M=1.6+/-0.1). By measuring the electron temperature profile behind each shock front, we determine the timescale for the electron population to thermally equilibrate with the shock-heated ions. We find that the temperature profile behind the bow shock is consistent with the timescale for Coulomb collisional equilibration and the postshock temperature is lower than expected for instant shock-heating of the electrons. Although like the Bullet cluster the electron temperatures behind the upstream shock front are hotter than expected, favouring the instant heating model, the uncertainty on the temperature values is greater here and there is significant substructure complicating the interpretation. We also measured the width of each shock front and the contact discontinuity on the leading edge of the subcluster core to investigate the suppression of transport processes in the ICM. The upstream shock is ~440 kpc in length but appears remarkably narrow over this distance with a best-fit width of only 6^{+5}_{-3} kpc compared with the mean free path of 23+/-5 kpc. The leading edge of the subcluster core is also narrow with an upper limit on the width of only 2 kpc separating the cool, multiphase gas at 0.5-2 keV from the shock-heated surrounding ICM at ~6 keV. The strong suppression of diffusion and conduction across this edge suggests a magnetic draping layer may have formed around the subcluster core.[abridged]

title: Κρυπτανάλυση με χρήση μεθόδων τεχνητής νοημοσύνης
Creators: name: Μπογιαννιδου Μαρια
Publisher: name: Technical University of Crete
Year: 2021

description:   Η παρούσα μεταπτυχιακή διατριβή αφορά στην κρυπτανάλυση με χρήση μεθόδων τεχνητής νοημοσύνης. Η κρυπτανάλυση, η αποκωδικοποίηση δηλαδή κρυπτογραφημένων πληροφοριών, αποτελεί πρόκληση ανά τους αιώνες. Εκτός από την εφαρμογή της για την απόκτηση πληροφοριών στις οποίες δεν επιτρέπεται η πρόσβαση, χρησιμοποιείται επίσης και για να εντοπίζει τις αδυναμίες και τα τρωτά σημεία κάθε κρυπτοσυστήματος, πριν αυτό εφαρμοστεί. Η κρυπτανάλυση είναι ένα πολύ σημαντικό βήμα στον έλεγχο της δύναμης κάθε κρυπτοσυστήματος.
Την τελευταία δεκαετία έχει παρατηρηθεί ένα αυξανόμενο ενδιαφέρον στην εφαρμογή  μεθόδων  Τεχνητής Νοημοσύνης σε προβλήματα που προκύπτουν στον τομέα της κρυπτογραφίας και της κρυπτανάλυσης. Αυτό συμβαίνει λόγω της αποτελεσματικότητας των μεθόδων αυτών στον χειρισμό δύσκολων προβλημάτων και στον ιδιαιτέρως σπουδαίο ρόλο των αυτοματοποιημένων τεχνικών στον σχεδιασμό και στην κρυπτανάλυση κρυπτοσυστημάτων. Η τεχνητή και υπολογιστική νοημοσύνη έχουν αρκετά κοινά χαρακτηριστικά  με την επιστήμη της κρυπτολογίας, ιδιαίτερα με την  κρυπτανάλυση. Κάποια από αυτά είναι η επεξεργασία μεγάλου όγκου δεδομένων και οι εργασίες σε μεγάλους χώρους αναζήτησης . Ο κρυπταναλυτής ψάχνει το κατάλληλο κλειδί για κάθε συγκεκριμένη  αποκρυπτογράφηση μέσα σε πολλές πληροφορίες και η τεχνητή νοημοσύνη μια κατάλληλη λύση σε ένα πλήθος πιθανών λύσεων. Αυτή η εργασία λοιπόν, θα παρουσιάσει αλγόριθμους και μεθόδους τεχνητής νοημοσύνης που χρησιμοποιούνται για κρυπτανάλυση.
 Αρχικά  θα παρουσιαστούν βασικοί ορισμοί και έννοιες και θα γίνει μία μικρή ιστορική αναδρομή. Έπειτα, θα αναλυθούν οι Κρυπτογραφικοί Αλγόριθμοι Δέσμης (Block ciphers), με έμφαση στις συμμετρικές δομές Feistel και τον κρυπταλγόριθμο DES (Data Encryption Standard ).Στην συνέχεια, θα αναλυθούν οι αλγόριθμοι που έχουν εμπνευστεί από την φυσική εξέλιξη και την κοινωνική συμπεριφορά, δηλαδή οι αλγόριθμοί Εξελικτικού Υπολογισμού (Evolutionary Computation-EC). Έμφαση θα δοθεί στον αλγόριθμο PSO (Particle Swarm Optimization, ’’Βελτιστοποίησης Σμήνους Σωματιδίων ‘’ ).
Τα επόμενα που θα παρουσιαστούν θα είναι τα Τεχνητά Νευρωνικά Δίκτυα (Artificial Neural Networks ,ANN) και οι διάφορες εφαρμογές τους, όπως στην κρυπτογραφία ελλειπτικών καμπυλών. Στη συνέχεια, θα αναλυθεί ένα είδος  των ANN, το Πολυωνυμικό Νευρικό Δίκτυο Κορυφογραμμής (Ridge Polynomial Network -RPN). Τέλος, θα επισημανθούν παρατηρήσεις μέσα από την παρουσίαση πινάκων αποτελεσμάτων πειραμάτων.
Στο κεφάλαιο 6 θα παρουσιαστεί μία μελέτη για την κρυπτανάλυση του κρυπτογραφήματος Speck32/64 με χρήση νευρωνικών distinguishers και δικτύων. Το Speck θεωρείται ένα από το πιο απροσπέλαστα κρυπτογραφήματα και η κρυπτανάλυση του αποτελεί μεγάλη πρόκληση. Κυρίως έχει επιτευχθεί σε Speck μειωμένων επαναλήψεων.
Κάποιες έννοιες δυστυχώς δεν υπάρχουν στην ελληνική ορολογία και θα αναγράφονται στα αγγλικά. Στο τέλος υπάρχει ένα κεφάλαιο με παρουσίαση της ορολογίας και ανάλυση διάφορων εννοιών που θα αναφερθούν στην παρούσα διατριβή και θεώρησα ότι χρήζουν επεξήγησης.

description: Femtosecond spectroscopy is applied to study transient electronic and lattice processes in bismuth. Components with relaxation times of 1 ps, 7 ps and ~ 1 ns are detected in the photoinduced reflectivity response of the crystal. To facilitate the assignment of the observed relaxation to the decay of particular excited electronic states we use pump pulses with central wavelengths ranging from 400 nm to 2.3 mum. Additionally, we examine the variation of parameters of coherent A1g phonons upon the change of excitation and probing conditions. Data analysis reveals a significant wavevector dependence of electron-hole and electron- phonon coupling strength along Γ--T direction of the Brillouin zone.

Recently identified Asian Objects from the Eduard & Margaret Fuchs collection

Publisher: name: Journal for Art Market Studies

description: duard Fuchs (1870-1940) was one of the most successful authors of popular books on cultural history in Germany around 1900. Quite a number of his books were based on documentary images or artworks, which may have inspired him to form his own collection. Notably, he owned prints by Honoré Daumier and paintings and sketches by Max Slevogt and Max Liebermann. This essay is the first attempt to record his East Asian collection, which is almost unknown although more than one thousand East Asian objects were auctioned at Lepke in 1937 and 1938; and Fuchs’s books entitled Tang-Plastik. Chinesische Grabkeramik des 7. - 10. Jahrhunderts, on Tang sculpture, and Dachreiter und verwandte chinesische Keramik des 15. bis 18. Jahrhunderts, on Ming roof riders, became standard publications on Chinese decorative art. Fuchs’s political background as a Socialist enabled him to analyze colonialism and art pillage, while being aware of national liberation movements at an early stage. Establishment experts in Chinese art such as Otto Kümmel criticized him because of his Marxist approach to art history, but the left-wing philosopher Walter Benjamin regarded him as a pioneer in the discovery of the qualities of Asian decorative art. This essay is based on an ongoing provenance project that was initiated by Fuchs’ heirs and funded by the German Lost Art Foundation. With the active support of museums and many researcher colleagues, fourteen objects could be traced to date, including highlights of Eduard Fuchs’s famous roof rider collection.

Risk-benefit tradeoffs for NSAIDs for the management of rheumatoid arthritis (RA)- a discrete choice experiment (DCE)
Creators: name: Chen, Belinda Shin-Chieh
Publisher: name: University of British Columbia
Year: 2010

description: Background Nonsteroidal anti-inflammatory drugs (NSAIDs) are drugs that are used to reduce pain and inflammation in those with rheumatoid arthritis (RA). There are two types of NSAID drugs available for treating those with RA, nonselective NSAIDs and coxibs. Rofecoxib, is a coxib that was taken off the market due to evidence of an increased risk of cardiovascular events from the use of this drug relative to placebo. However, there are those who benefited from this drug and were willing to take the risk. Objective The primary objective of this study is to use a DCE to quantify the risk preferences of those with RA, i.e., how much potential risk they are willing to accept in order to gain a specified potential benefit. It is hypothesized that given greater potential benefit, those with RA will be willing to accept greater risk of AEs, in particular myocardial infarction and stroke, than what they are currently exposed to in their NSAIDs. Methodology The DCE requires the creation of a questionnaire-based survey that was administered online to a sample of RA patients. Discrete choice experimentation allows the elicitation of patients’ preference for different treatment attributes through paired choice scenarios where respondents are required to choose between treatment options based on the risks of adverse events and benefits associated with each treatment. Conclusions For those with RA, the benefits outweigh the risks. In particular, given greater chance of benefit with improvement in pain and function, RA patients are willing to accept a greater risk of ulcers, dyspepsia, myocardial infarction, and stroke than what is present in current and past NSAIDs. Increased knowledge of the risk preferences of those with RA may aid decision-makers in better-informed drug approval and withdrawal decisions, thereby preventing patients from losing access to potentially beneficial drugs.

description: We extend the discrete Regge action of causal dynamical triangulations to include discrete versions of the curvature squared terms appearing in the continuum action of (2+1)-dimensional projectable Horava-Lifshitz gravity. Focusing on an ensemble of spacetimes whose spacelike hypersurfaces are 2-spheres, we employ Markov chain Monte Carlo simulations to study the path integral defined by this extended discrete action. We demonstrate the existence of known and novel macroscopic phases of spacetime geometry, and we present preliminary evidence for the consistency of these phases with solutions to the equations of motion of classical Horava-Lifshitz gravity. Apparently, the phase diagram contains a phase transition between a time-dependent de Sitter-like phase and a time-independent phase. We speculate that this phase transition may be understood in terms of deconfinement of the global gravitational Hamiltonian integrated over a spatial 2-sphere.
