description: The paper under study presents a concept relating to language development, linguistic-constructivist teleology and a notion of the comprehension of developed language, also with respect to the language of international communication. A philosophical, methodological and linguistic criticism of both the concept and the term “development” is displayed herein. With relation to language development, three aspects of language as a communicative system are considered from the point of view of L. V. Shcherba: a speech activity, a language system and a language material; three functions of a speech activity are analysed from the standpoint of V. V. Kolesov: communication, translation and transmutation. Some properties of developed language are selected and an issue of inconsistency in the application of a developed living language as a language of international communication is raised. Some characteristics of language evolution and involution are determined. An importance is specified of an activity-oriented approach and the purposefulness of language development as a subjective factor of the process under investigation. A negative impact of the restrictive, “subtractive” normalisation of language is denoted.
A road pricing strategy for Greater Vancouver
Creators: name: Kamnitzer, David

description: The traditional response of governments to the problem of traffic congestion has been to increase transport capacity. This policy focus has not been effective. Despite significant investment in highways, roads, and public transit, traffic conditions in most major cities continue to deteriorate. Furthermore, increased public awareness of the environmental effects of the automobile together with the fiscal reality facing all governments in Canada reduces the capacity for future road building projects. A new approach to urban transport policy is therefore required. Road pricing has long been advocated by economists as a means of making more efficient use of the road network. Unlike traditional flat rate tolls, road pricing charges would vary based on prevailing traffic conditions. Charging motorists for road space during congested peak periods would induce some motorists to switch to alternate modes or to make their trips at less congested times. Despite its economic rational, road pricing has yet to be implemented on a wide scale. Previous road pricing schemes have tended to focus on economic and technical issues to the exclusion of political concerns. In virtually all cases where road pricing has been proposed, political opposition has caused road pricing plans to be significantly scaled back or abandoned all together. If road pricing is to be implemented, future plans will have to address political as well as economic and technical issues. This thesis examines the political and economic issues raised by road pricing. Using Greater Vancouver as a case study, the thesis seeks answers to the key design questions involved in implementing a road pricing system. The principle findings of this research are: (1) road pricing should be presented as a means of making better use of the region's transportation system, not as a source of government revenue; (2) road pricing revenues should be used to improve transit, offset existing taxes, and promote high density housing along major transit corridors; (3) road pricing should be implemented on the Lions Gate Bridge as a demonstration project; and (4) road pricing measures should be integrated with transportation and land development policies.

description: We consider non(anti)commutative (NAC) deformations of d=1 N=2 superspace. We find that, in the chiral base, the deformation preserves only a half of the original (linearly realized) supercharge algebra, as it usually happens in NAC field theories. We obtain in terms of a real supermultiplet a closed expression for a deformed Quantum Mechanics Lagrangian in which the original superpotential is smeared, similarly to what happens for the two dimensional deformed sigma model. Quite unexpectedly, we find that a second conserved charge can be constructed which leads to a nonlinear field realization of the supersymmetry algebra, so that finally the deformed theory has as many conserved supercharges as the undeformed one. The quantum behavior of these supercharges is analyzed.

description: A model that can simultaneously explain Dark Matter relic density and the apparent matter anti-matter imbalance of the universe has been recently proposed. The model requires $b$-hadron branching fractions to Dark Matter at the per mille level. The $b$-hadrons decay to a dark sector baryon, $ψ_{\rm{DS}}$, which has a mass in the region $940$ MeV/c$^{2} \leq m(ψ_{\rm{DS}}) \leq 4430$ MeV/c$^{2}$. In this paper, we discuss the sensitivity of the LHCb experiment to search for this dark baryon, covering different types of topology and giving prospects for Runs 3 and 4 of the LHC, as well as for the proposed Phase-II Upgrade. We show that the LHCb experiment can cover the entire mass range of the hypothetical dark baryon.

description: Recent DFT calculations for Ba2CoO4 (BCO) and neutron scattering experiments for SrRuO3 (SRO) have shown that oxygen develops a magnetic polarization. Moreover, DFT calculations for these compounds also unveiled unexpected nodes in the spin density, both along Co-O and Ru-O. For BCO, the overall antiferromagnetic state in its triangular lattice contains unusual zigzag spin patterns. Here, using simple model calculations supplemented by DFT we explain and extend these results. We predict that ligands that in principle should be spinless, such as O$^{2-}$, will develop a net polarization when they act as electronic bridges between transition metal (TM) spins ferromagnetically ordered, regardless of the number of intermediate ligand atoms. The reason is the hybridization between atoms and mobility of the electrons with spins opposite to those of the closest TM atoms. Moreover, for bonds with TMs antiferromagnetically ordered, counterintuitively our calculations show that oxygens should also have a net magnetization for the super-super-exchange cases TM-O-O-TM while for only one oxygen, as in Cu-O-Cu, the O-polarization should cancel. Our simple model also allows us to explain the presence of nodes based on the antibonding character of the dominant singly occupied molecular orbitals along the TM-O bonds. Finally, the zigzag pattern order becomes the ground state mainly due to the influence of the Hubbard $U$, that creates the moments, in combination with a robust easy-axis anisotropy that suppresses the competing 120$^{\circ}$ degree antiferromagnetic order of a triangular lattice. Our predictions are generic and should be applicable to any other compound with characteristics similar to those of BCO and SRO.

description: We extend previous work on homogeneous bilayers to calculate the barriers to fusion of planar bilayers which contain two different amphiphiles, a lamellae-former and a hexagonal former, with different compositions of the twoin each leaf. Self-consistent field theory is employed, and both standard and alternative pathways are explored. We first calculate these barriers as the amount of hexagonal former is increased equally in both leaves to levels appropriate to the plasma membrane of human red blood cells. We follow these barriers as the composition of hexagonal-formers is then increased in the cis layer and decreased in the trans layer, again to an extent comparable to the biological system. We find that, while the fusion pathway exhibits two barriers in both the standard and alternative pathways, in both cases the magnitudes of these barriers are comparable to one another, and small, on the order of 13 kT. As a consequence, one expects that once the bilayers are brought sufficiently close to one another to initiate the process, fusion should occur rapidly.

description: Turbulent winds and gusts fluctuate on a wide range of timescales from milliseconds to minutes and longer, a range that overlaps the timescales of avian flight behavior, yet the importance of turbulence to avian behavior is unclear. By combining wind speed data with the measured accelerations of a golden eagle (Aquila chrysaetos) flying in the wild, we show that the eagle's accelerations can be explained by a linear interaction with turbulence for timescales between about 1/2 and 10 s. These timescales are comparable to those of typical eagle behaviors, corresponding to between about 1 and 25 wingbeats, and to those of turbulent gusts both larger than the eagle's wingspan and smaller than large-scale atmospheric phenomena such as convection cells. The eagle's accelerations exhibit power spectra and intermittent activity characteristic of turbulence, and increase in proportion to the turbulence intensity. Intermittency results in accelerations that are occasionally several times stronger than gravity, and much larger than the ones we experience while driving, for instance. These imprints of turbulence on the bird's movements need to be further explored to understand the energetics of birds and other volant lifeforms, to improve our own methods of flying through ceaselessly turbulent environments, and to engage airborne wildlife as distributed probes of the changing conditions in the atmosphere.

description: In this work we present a comprehensive analysis of collective electronic fluctuations and their effect on single-particle properties of the Hubbard model. Our approach is based on a standard dual fermion/boson scheme with the interaction truncated at the two-particle level. Within this framework we compare various approximations that differ in the set of diagrams (ladder vs exact diagrammatic Monte Carlo), and/or in the form of the four-point interaction vertex (exact vs partially bosonized). This allows to evaluate the effect of all components of the four-point vertex function on the electronic self-energy. In particular, we observe that contributions that are not accounted for by the partially bosonized approximation for the vertex have only a minor effect on electronic degrees of freedom in a broad range of model parameters. In addition, we find that in the regime, where the ladder dual fermion approximation provides an accurate solution of the problem, the leading contribution to the self-energy is given by the longitudional bosonic modes. This can be explained by the fact that contributions of transverse particle-hole and particle-particle modes partially cancel each other. Our results justify the applicability of the recently introduced dual triply irreducible local expansion (D-TRILEX) method that represents one of the simplest consistent diagrammatic extensions of the dynamical mean-field theory. We find that the self-consistent D-TRILEX approach is reasonably accurate also in challenging regimes of the Hubbard model, even where the dynamical mean-field theory does not provide the optimal local reference point (impurity problem) for the diagrammatic expansion.

description: We consider a scenario of modified gravity, which is generic to late-time acceleration, namely, acceleration in the Jordan frame and no acceleration in the Einstein frame. The possibility is realized by assuming an interaction between dark matter and the baryonic component in the Einstein frame which is removed by going to the Jordan frame using a disformal transformation giving rise to an exotic effective fluid responsible for causing phantom crossing at late times. In this scenario, past evolution is not distinguished from $Λ$CDM but late time dynamics is generically different due to the presence of phantom crossing that causes a monotonous increase in the expansion rate giving rise to distinctive late-time cosmic feature. The latter can play a crucial role in addressing the tension between the observed value of Hubble parameter by CMB (Cosmic Microwave Background) measurements and the local observations. We demonstrate that the Hubble tension significantly reduces in the scenario under consideration for the chosen scale factor parametrizations. The estimated age of the universe in the model is well within the observational bounds in the low and high red-shift regimes.

description: Photovoltaic systems are sensitive to cloud shadow projection, which needs to be forecasted to reduce the noise impacting the intra-hour forecast of global solar irradiance. We present a comparison between different kernel discriminative models for cloud detection. The models are solved in the primal formulation to make them feasible in real-time applications. The performances are compared using the j-statistic. The infrared cloud images have been preprocessed to remove debris, which increases the performance of the analyzed methods. The use of neighboring features of the pixels also leads to a performance improvement. Discriminative models solved in the primal yield a dramatically lower computing time along with high performance in the segmentation.

With the additional constraint from the world average of the flavor-specific B_s^0 lifetime, we obtain Delta Gamma_s = (Γ_L - Γ_H) = 0.13 +- 0.09 ps$^{-1}$ and phi_s = -0.70 ^{+0.47}_{-0.39}. The data sample corresponds to an integrated luminosity of 1.1 fb^{-1} accumulated with the D0 detector at the Fermilab Tevatron Collider.

Regional conservation planning strategies for British Columbia: the case of the Sunshine coast
Creators: name: McMullen, McMullen
Publisher: name: University of British Columbia
Year: 2009

description: The thesis takes a normative, yet pragmatic approach, in examining how the protection of habitat and ecological functions can be improved through changing current uncoordinated, sectoral decision-making processes into a holistic, cooperative approach to guide planning at the local level. In rapidly growing regions on the urban/rural fringe such as the Sunshine Coast, towns, rural areas and large wildernesses form a complex matrix of land uses across the landscape which require the integration of provincial and local government planning. Thus, a case is made for a decision-making process that generates a conservation strategy, integrating local and provincial planning at the scale of regional districts in British Columbia. The literature is reviewed to identify principles for a conservation strategy approach to decision-making which include: a consensus-based process, cross-sectoral government coordination, broad-based public involvement, and non-governmental partnerships for implementation. Secondly, the literature pertaining to several regional approaches to conservation planning is reviewed including: parks system planning, landscape ecology and bioregional theory. From these two sources of literature, a hybrid model of the regional conservation planning strategy is formed. Using criteria derived from this hybrid model to evaluate the effectiveness of planning processes, the provincial conservation planning framework is evaluated. The policies of the Commission on Resources and Environment, the provincial government’s Land and Resource Management Planning process and the Protected Areas Strategy are evaluated according to the criteria. Fourthly, conservation planning on the Sunshine Coast is examined, and a case study of the Sechelt Inlets Coastal Strategy is evaluated against the criteria. By evaluating both the provincial planning framework and the local case study, conclusions can be drawn on the need for regional conservation planning strategy processes in rapidly developing areas at the urban/rural fringe. Finally, recommendations are made for changes to provincial and regional district policies to facilitate more effective conservation planning for the Sunshine Coast Regional District and other regions in British Columbia.
Minimum-energy pulses for quantum logic cannot be shared

description: We show that if an electromagnetic energy pulse with average photon number is used to carry out the same quantum logical operation on a set of N atoms, either simultaneously or sequentially, the overall error probability in the worst case scenario (i.e., maximized over all the possible initial atomic states) scales as N^2/. This means that in order to keep the error probability bounded by Nε, with ε~ 1/, one needs to use N/εphotons, or equivalently N separate "minimum-energy'' pulses: in this sense the pulses cannot, in general, be shared. The origin for this phenomenon is found in atom-field entanglement. These results may have important consequences for quantum logic and, in particular, for large-scale quantum computation.

A novel metabolic representation for the discovery of modules of chemical transformations
Creators: name: Sorokina, Maria
name: Vallenet, David
Publisher: name: F1000Research
Year: 2015

description: The identification of functional modules in metabolic networks allows the improvement of functional annotation and the discovery of new metabolic pathways and enzymatic reactions. In this context, we propose a novel representation of a global metabolic network where reactions sharing a same chemical transformation type are grouped in reaction molecular signatures (RMS) (Carbonell, Carlsson, & Faulon, 2013, http://molsig.sourceforge.net). RMS have the advantage of being an automatic and expert-independent reaction classification that is much finer and has a wider coverage than the Enzyme Commission classification.
Starting from a directed reaction network, reaction vertices sharing the same RMS are grouped in single vertices and edges are established from the initial reaction connectivity. Several scores are then computed for each path in the RMS network in order to evaluate known metabolic pathway conservation and to discover new ones. The first score, scoreRea, is computed using the average number of reactions and represents the chemical conservation of the paths in the whole metabolism. The second one, scoreProt, is based on the number of proteins associated to each RMS and represents the enzymatic conservation among the tree of life. The next one, scoreTopo, is based on the PageRank centrality and depicts the topological importance of the RMS sequence in the metabolic network. The last score, scoreMeta, is the number of different reaction paths among known metabolic pathways grouped in a RMS path and represents the chemical transformation conservation across the known part of the metabolism. The most conserved RMS paths are then identified and used to understand the linkage between the path conservation types (chemical, enzymatic and topological) and the type of metabolic pathway (biosynthesis, degradation, detoxification, etc.).
We show that our representation of metabolism has an interesting predictive potential and can be used to identify most conserved parts of the metabolism and to find new metabolic modules. Furthermore, the combination of different scores can be used to predict the metabolic role of new pathways using supervised machine learning. Associated to genomic context data like operons and syntenies, conserved paths of chemical transformations will be a useful tool for functional annotation of genes and groups of genes of unknown function.

description: We study the renormalization group running of axion couplings while taking into account that the Standard Model can be extended to its supersymmetric extension at a certain energy scale below the axion decay constant. We then apply our results to three different classes of axion models, i.e. KSVZ-like, DFSZ-like, and string-theoretic axions, and examine if string-theoretic axions can be distinguished from others by having a different pattern of low energy couplings to the photon, nucleons and electron. We find that the low energy couplings of string-theoretic axions have a similar pattern as those of KSVZ-like axions but yet reveal a sizable difference which might be testable in future axion search experiments. We also note that the coupling of KSVZ-like QCD axions to the electron is dominated by a three-loop contribution involving the exotic heavy quark, gluons, top quark and Higgs field.

description: Designing flat sheets that can be made to deform into 3D shapes is an area of intense research with applications in micromachines, soft robotics, and medical implants. Thus far, such sheets were designed to adopt a single target shape. Here, we show that through anisotropic deformation applied inhomogenously throughout a sheet, it is possible to design a single sheet that can deform into multiple surface geometries upon different actuations. The key to our approach is development of an analytical method for solving this multi-valued inverse problem. Such sheets open the door to fabricating machines that can perform complex tasks through cyclic transitions between multiple shapes. As a proof of concept we design a simple swimmer capable of moving through a fluid at low Reynolds numbers.

description: The role of technological advancements to address environmental issues is an important topic, but there is often a lack of understanding of the nature of those technologies. This study is part of a European Union-funded project, exploring perceptions and experiences with Carbon Capture, Utilization and Storage technologies (CCUS). Based on five semi-structured interviews, this multiple case study explores the beliefs and understanding of five people concerning the implementation of CCUS and the installation of a demonstration facility in a nearby location to them. The interview protocol was partly based on a video developed by the project to inform the public about CCUS technologies. We followed an instrumental approach to the data collection as the findings of this study will be used to inform policy writing within a European Union context. Preliminary findings indicate that 1) there is low awareness of CCUS technologies, 2) based on past experiences there is scepticism on the adoption of new technologies and the organizations involved, and 3) more information is needed for the public to form an opinion on these technologies.

Στην πλειονότητα των έργων, ο δόλος χρησιμοποιείται από γυναικείους χαρακτήρες και συχνά λειτουργεί ως αντιστάθμισμα της φυσικής κατωτερότητάς τους στη σωματική ισχύ απέναντι στους άνδρες. Αντιθέτως, οι άνδρες, στις περισσότερες περιπτώσεις, εμφανίζονται ακατάλληλοι για τη χρήση δόλου, καθώς το μέσο αυτό είναι κάτι διαμετρικά αντίθετο με τα ανδρικά ιδανικά, τα οποία περιορίζουν τις επιλογές τους στην ευθύτητα και τη σωματική δύναμη. Έτσι, για τους ανδρικούς χαρακτήρες η χρήση δόλου δεν αποτελεί συνήθως φυσική επιλογή, αλλά υιοθετείται αναγκαστικά, όταν οι περιστάσεις δεν επιτρέπουν κάποιο άλλο, περισσότερο ανδρικό, μέσο.

description: In Greek tragedy deceit occurs frequently. It is a powerful weapon that succeeds when all other means is deemed inappropriate. In most plays deceit is used by women and often functions as a counterbalance to their inferiority to men in terms of physical strength. In most cases men are unsuitable for the use of deceit as it is opposed to their ideals, which limit their options to directness and physical strength. Thus to male characters deception is not a natural choice but a necessary evil foisted upon them when other, manlier, methods fail. In this thesis I discuss Euripides’ Helen, Iphigenia in Tauris and Hecuba, Aeschylus’ Choephori, and Sophocles’ Electra, and I examine the function of deceit from the perspective of gender, intelligence, age and nationality of the deceiving characters

description: No polynomial-time algorithm is known to test whether a sparse polynomial G divides another sparse polynomial $F$. While computing the quotient Q=F quo G can be done in polynomial time with respect to the sparsities of F, G and Q, this is not yet sufficient to get a polynomial-time divisibility test in general. Indeed, the sparsity of the quotient Q can be exponentially larger than the ones of F and G. In the favorable case where the sparsity #Q of the quotient is polynomial, the best known algorithm to compute Q has a non-linear factor #G#Q in the complexity, which is not optimal. In this work, we are interested in the two aspects of this problem. First, we propose a new randomized algorithm that computes the quotient of two sparse polynomials when the division is exact. Its complexity is quasi-linear in the sparsities of F, G and Q. Our approach relies on sparse interpolation and it works over any finite field or the ring of integers. Then, as a step toward faster divisibility testing, we provide a new polynomial-time algorithm when the divisor has a specific shape. More precisely, we reduce the problem to finding a polynomial S such that QS is sparse and testing divisibility by S can be done in polynomial time. We identify some structure patterns in the divisor G for which we can efficiently compute such a polynomial~S.

description: This thesis discusses the interaction of prosodic constituency with segmental and tonal analyses. This is done through the examination of two phonological reduction processes, Nasal Spreading and Vowel Deletion, in colloquial Tokyo Japanese. This thesis consists of two chapters. Chapter I analyzes Nasal Spreading, a nasal assimilation process, which occurs when the negative suffix /nai/ is attached to verb roots. In order to explain this process, first, the segmental conditions for Nasal Spreading are examined. Among verbs, only /r/-final roots trigger assimilation. This is explained in terms of Rhotic Underspecification (Mester and Ito 1989, and others), Feature Class Theory (Padgett 1994), and Feature Licensing (Ito, Mester, and Padgett 1994), demonstrating that the target /r/ lacks specification under the root node. The prosodic account analyzes Nasal Spreading as a syllabification process. Nasal Spreading adds one mora; whereas the standard form, a general form in /nai/-suffixation, epenthesizes /a/ to break up the consonant cluster, by adding a mora and a syllable to the output string. The prosodic account also deals with the interaction with tonal system. A disyllabic requirement on the derived base can be explained with respect to a violation of tonal agreement. The tone melodies in the colloquial and standard forms must agree; however, the constraints on Accent Shift or Initial Lowering require minimally disyllabic strings [@ @] in the base for the agreement. Chapter II discusses Vowel Deletion. In Vowel Deletion as well the interaction of the three types of structure is discussed. Segmentally, the type of compounds and vowels for deletion are specified. This is examined under the Theory of Underspecification (Archangeli 1988), and/or under the sonority scale approach (Prince and Smolensky 1993) . The prosodic analysis deals with domain specification. The lexical tone in the second constituent of the compound blocks deletion; because it blocks formation of the single tone domain which would be the site for Vowel Deletion. Only one tonal peak is allowed in a single tone domain. The blocker splits a string of compound into two; Vowel Deletion cannot apply between two domains. In Nasal Spreading and Vowel Deletion, segmental, prosodic, and tonal principles interact to determine the optimal output strings. The intricate interplay is accounted for with the Optimality Theoretic approach.

description: The bright short-hard GRB 051103 was triangulated by the inter-planetary network and found to occur in the direction of the nearby M81/M82 galaxy group. Given its possible local-Universe nature, we searched for an afterglow associated with this burst. We observed the entire 3-sigma error quadrilateral using the Palomar 60-inch robotic telescope and the Very Large Array (VLA) about three days after the burst. We used the optical and radio observations to constrain the flux of any afterglow related to this burst, and to show that this burst is not associated with a typical supernova out to z~0.15. Our optical and radio observations, along with the Konus/Wind gamma-ray energy and light curve are consistent with this burst being a giant flare of a Soft Gamma-ray Repeater (SGR) within the M81 galaxy group. Furthermore, we find a star forming region associated with M81 within the error quadrilateral of this burst which supports the SGR hypothesis. If confirmed, this will be the first case of a soft gamma-ray repeater outside the local group.

description: Spectroscopy is a powerful tool to probe physical, chemical, and biological systems. Recent advances in microfabrication have introduced novel, intriguing mesoscopic quantum systems including superconductor-semiconductor hybrid devices and topologically non-trivial electric circuits. A sensitive, general purpose spectrometer to probe the energy levels of these systems is lacking. We propose an on-chip absorption spectrometer functioning well into the millimeter wave band which is based on a voltage-biased superconducting quantum interference device. We demonstrate the capabilities of the spectrometer by coupling it to a variety of superconducting systems, probing phenomena such as quasiparticle and plasma excitations. We perform spectroscopy of a microscopic tunable non-linear resonator in the 40-50 GHz range and measure transitions to highly excited states. The Josephson junction spectrometer, with outstanding frequency range, sensitivity, and coupling strength will enable new experiments in linear and non-linear spectroscopy of novel mesoscopic systems.

description: Understanding the electrodes' surface morphology influence on the ions' distribution is essential for designing the supercapacitors with enhanced energy density characteristics. We develop a model for the structure of electrolytes near the rough surface of electrodes. The model describes an effective electrostatic field's increase and associated intensification of ions' spatial separation at the electrode-electrolyte interface. These adsorption-induced local electric and structure properties result in notably increased values and sharpened form of the DC dependence on the applied potential. Such capacitance behavior is observed in many published simulations, and its description is beyond the capabilities of the established flat-electrodes theories. The proposed approach could extend the quantitatively verified models providing a new instrument of the electrodes surface-parameters optimization for specific electrolytes.

description: We report on the first ultracool dwarf discoveries from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey Early Data Release (LAS EDR), in particular the discovery of T dwarfs which are fainter and more distant than those found using the 2MASS and SDSS surveys. We aim to show that our methodologies for searching the ~27 sq degs of the LAS EDR are successful for finding both L and T dwarfs $via$ cross-correlation with the Sloan Digital Sky Survey (SDSS) DR4 release. While the area searched so far is small, the numbers of objects found shows great promise for near-future releases of the LAS and great potential for finding large numbers of such dwarfs. Ultracool dwarfs are selected by combinations of their YJH(K) UKIDSS colours and SDSS DR4 z-J and i-z colours, or, lower limits on these red optical/infrared colours in the case of DR4 dropouts. After passing visual inspection tests, candidates have been followed up by methane imaging and spectroscopy at 4m and 8m-class facilities. Our main result is the discovery following CH4 imaging and spectroscopy of a T4.5 dwarf, ULASJ 1452+0655, lying ~80pc distant. A further T dwarf candidate, ULASJ 1301+0023, has very similar CH4 colours but has not yet been confirmed spectroscopically. We also report on the identification of a brighter L0 dwarf, and on the selection of a list of LAS objects designed to probe for T-like dwarfs to the survey J-band limit. Our findings indicate that the combination of the UKIDSS LAS and SDSS surveys provide an excellent tool for identifying L and T dwarfs down to much fainter limits than previously possible. Our discovery of one confirmed and one probable T dwarf in the EDR is consistent with expectations from the previously measured T dwarf density on the sky.

description: Η εργασία προσπαθεί να αξιολογήσει την ηθικότητα πράξεων που σχετίζονται με τη σεξουαλικότητα. Το κάνει όμως με τέτοιο τρόπο, ώστε να διερευνήσει τα ηθικά όρια του ποινικού νόμου και να απαντήσει στο ερώτημα του εύρους των πράξεων που μπορεί να ποινικοποιεί ένα φιλελεύθερο και δημοκρατικό ποινικό σύστημα. Στο πρώτο μέρος διερευνά την έννοια της συναίνεσης. Η έννοια της συναίνεσης έχει αναδειχθεί στο κέντρο της προσοχής όσων ασχολούνται με τον αγώνα για τον περιορισμό των αξιόποινων σεξουαλικών πράξεων, της σεξουαλικής βίας και του σεξουαλικού καταναγκασμού. Στο δεύτερο μέρος διερευνά ορισμένα ειδικά θέματα, στα οποία η ύπαρξη ή μη έγκυρης συναίνεσης σε κάποια σεξουαλική πράξη είναι αμφίβολη. Αρχικά, αναζητούνται οι προϋποθέσεις, υπό τις οποίες η απειλή μπορεί να καταστήσει άκυρη τη συναίνεση και να θεμελιώσει εξαναγκασμό του θύματος. Ακολούθως, αναζητούνται οι προϋποθέσεις, υπό τις οποίες η εξαπάτηση μπορεί να θεμελιώσει εξαναγκασμό του θύματος, ενώ στο τέλος τίθεται το ηθικό ζήτημα, αν η συνουσία με μεθυσμένη γυναίκα, που συναινεί ακριβώς επειδή είναι μεθυσμένη, πρέπει να αποδοκιμαστεί. Βαθύτερος στόχος της εργασίας είναι να δείξει πως η επικέντρωση στη συναίνεση για τον ηθικό και ποινικό ορισμό του σεξουαλικού εγκλήματος (αντί της έννοιας του εξαναγκασμού),ως εγγύηση της σεξουαλικής αυτονομίας,αν και φαινομενικά θέτει το θύμα και τις επιλογές του στο κέντρο του ενδιαφέροντος και της προσοχής, ουσιαστικά φέρνει τα αντίθετα αποτελέσματα
description: This thesis tries to evaluate the morality of acts related to sexuality. But it does so, in order to examine the moral limits of criminal law and to answer the question regarding the range of acts that can be criminalized under a liberal and democratic criminal system. The first section examines the concept of consent. The concept of consent has become the centre of attention to those engaged in the fight to curb sexual crimes, sexual violence and sexual coercion. The second section examines some specific problems, in which the presence or not of valid consent is ambiguous. Initially, we examine the conditions under which threat can invalidate consent and establish the victim's coercion. Subsequently, we examine the conditions under which deception can establish victim's coercion, and finally we raise the issue whether having sex with a drunken woman, who consents precisely because she is drunk, should be disapproved. The deep purpose of this thesis is to prove that focusing on consent for the moral and criminal description of sexual crime (instead of the concept of coercion), as a guarantee of sexual autonomy, although it seems to place victim and its choices in the centre of interest and attention, actually brings the opposite effects
