description: Παρουσιάζονται οι γνωστότερες κριτικές προσεγγίσεις Αγγλοσαξώνων κυρίως-φεμινιστριών θεωρητικών. Τα σημεία εστίασης είναι:1) Η ανάλυση του Φουκώ για την άρρηκτη σχέση των συστημάτων γνώσης και των σχέσεων εξουσίας, 2) Η αντίληψη του Φουκώ ότι η ανθρώπινη σεξουαλικότητα και γενικά η ανθρώπινη ταυτότητα δεν έχει εγγενή, ουσιοκρατικά, διαχρονικά και διπολικά ως προς το φύλο χαρακτηριστικά, αλλά ότι υπόκειται σε σχέσεις εξουσίας, τις εμπεριέχει εν τη γενέσει της, τις συντηρεί και τις αναπαράγει. 3) Η αναγνώριση από τον Φουκώ του ίδιου του ανθρώπινου σώματος ως πεδίου άσκησης εξουσίας, μέσω του οποίου επιτυγχάνεται ο έλεγχος και κατασκευάζεται η υποκειμενικότητα. 4) Η ανάδειξη από τον Φουκώ των τοπικών λεπτών και βαθειών λειτουργιών της εξουσίας στην καθημερινή ζωή και όχι η επικέντρωση αποκλειστικά στην κεντρική πολιτική εξουσία και τους κεντρικούς πολιτικούς αγώνες. Σημεία φεμινιστικής κριτικής: 1) H θεώρηση του Φουκώ εντοπίζεται μόνο στο αρσεινικό υποκείμενο, ενώ αγνοούνται οι γυναίκες σαν υποκείμενο επιθυμίας και αυτοκυριαρχίας, σαν ηθικά δηλαδή υποκείμενα, 2) Ο Φουκώ παραβλέπει ότι τα πραγματικά σώματα αντιλαμβάνονται τον κόσμο και γίνονται αντιλιπτά μέσω του διπόλου αρσενικότητας και θηλυκότητας, 3) Η αντίληψη του Φουκώ δεν επιτρέπει τη συγκρότηση πολιτικών κινημάτων χειταφέτησης των γυναικών, αφού ούτως η άλλως τα δίκτυα εξουσίας μπορούν να διαχειρισθούν όλες τις συγκρούσεις.
description: In this work are presented the most well known critical approaches expressed by feminist theorists, mainly anglosaxons. The focus points are: 1) The Foucauldian analysis of the unbreakable relationship between the systems of Knowledge and the power relations, 2) The consideration that the human sexuality and the human identity in generall has no innate, essential, everlasting and according to the gender dipolar charachteristics, but it is subjected to power relations, it includes them since its genesis, it preserves and reproduces them, 3) The acknowledgement of the human body as a field of practising power, through which the control is succeeded and the subjectivity is constructed, 4) The enhancement of the local and deep functions of the power, in the daily life, instead of focusing only on the central political power and struggles. Points of feminist critics: 1) The analysis is located only to the masculine subject, while the women are ignored as subjects of desire and self-possession, 2) Foucault overlooks the fact that the real bodies inderstand the world and become understandable through the dipole of masculinity and femininity, 3) The Foucauldian conception doesn't allow the constitution of women's emancipation political movements, since the networks of power can manage all the conflicts.
Unparticles and inflation

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We study some of the roles for unparticles in an inflationary universe. Unparticles by themselves are not appropriate for generating the primordial perturbations since their power spectrum does not match what has been inferred from observations. In fact, when the scaling dimension for the unparticles exceeds three-halves, the unparticle power spectrum diverges. However, when a unparticle couples to an ordinary inflaton particle, loop corrections can produce a slight enhancement of the inflaton's power spectrum at longer wavelengths. We examine these loop corrections from unparticles in some detail to learn how they scale in the wavelength of a perturbation and how they depend on the scaling dimension of the field.

description: We consider the non-equilibrium dynamics of a weakly interacting Bose gas tightly confined to a highly elongated double well potential. We use a self-consistent time-dependent Hartree--Fock approximation in combination with a projection of the full three-dimensional theory to several coupled one-dimensional channels. This allows us to model the time-dependent splitting and phase imprinting of a gas initially confined to a single quasi one-dimensional potential well and obtain a microscopic description of the ensuing damped Josephson oscillations.

description: The influence of a quantizing magnetic field $H$ to the conductance of a tunnel point contact in the presence of the single defect has been considered. We demonstrate that the conductance exhibits specific magneto-quantum oscillations, the amplitude and period of which depend on the distance between the contact and the defect. We show that a non-monotonic dependence of the point-contact conductance results from a superposition of two types of oscillations: A short period oscillation arising from electron focusing by the field $H$ and a long period oscillation of Aharonov-Bohm-type originated from the magnetic flux passing through the closed trajectories of electrons moving from the contact to the defect and returning back to the contact.

Strangers in the House: the Legislative Press Gallery of British Columbia
Creators: name: Reeder, Sarah Katherine
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the dynamics and complexities of the press-politician relationship in the context of the British Columbia Legislature and Press Gallery. The relationship is examined from theoretical, historical/institutional, practical, and political perspectives. The evidence presented suggests that although the press-politician relationship is necessarily symbiotic, it is also characterized by conflict and attempts by both press and politicians to achieve independence of each other. As such, the relationship is most accurately described as one of "adversarial symbiosis." The sources of strain and the constructive elements of the relationship work in tandem to move the province closer to the ideals of legislative democracy as the relationship evolves over time. Provincial press galleries are notoriously under-documented, both through independent research and through their own administration. To date, there has not been a comprehensive study of the British Columbia Press Gallery as an institution of the Legislature. As a result, this thesis relies heavily on oral history, provided through semi-structured interviews with current and former members of the Press Gallery, and published biographies of B.C. journalists and politicians. This thesis was also informed by a review of the existing literature on the Canadian, Australian and British Parliamentary Press Galleries, archival research at the B.C. Legislative Library and Press Gallery offices and personal observation and analysis afforded by the author's six-month Legislative Internship in the B.C. Legislature.

description: Dynamics of a system that performs a large fluctuation to a given state is essentially deterministic: the distribution of fluctuational paths peaks sharply at a certain optimal path along which the system is most likely to move. For the general case of a system driven by colored Gaussian noise, we provide a formulation of the variational problem for optimal paths. We also consider the prehistory problem, which makes it possible to analyze the shape of the distribution of fluctuational paths that arrive at a given state. We obtain, and solve in the limiting case, a set of linear equations for the characteristic width of this distribution.

Solar Cycle Related Changes in the Helium Ionization Zones of the Sun

description: Helioseismic data for solar cycles 23 and 24 have shown unequivocally that solar dynamics changes with solar activity. Changes in solar structure have been more difficult to detect. Basu & Mandel (2004) had claimed that the then available data revealed changes in the HeII ionization zone of the Sun. The amount of change, however, indicated the need for larger than expected changes in the magnetic fields. Now that helioseismic data spanning two solar cycles are available, we have redone the analysis using improved fitting techniques. We find that there is indeed a change in the region around the HeII ionization zone that is correlated with activity. Since the data sets now cover two solar cycles, the time variation is easily discernible.

description: Motivated by the study of symmetries of C*-algebras, as well as by multivariate operator theory, we introduce the notion of an SU(2)-equivariant subproduct system of Hilbert spaces. We analyse the resulting Toeplitz and Cuntz-Pimsner algebras and provide results about their topological invariants through Kasparov's bivariant K-theory. In particular, starting from an irreducible representation of SU(2), we show that the corresponding Toeplitz algebra is equivariantly KK-equivalent to the algebra of complex numbers. In this way, we obtain a six term exact sequence of K-groups containing a noncommutative analogue of the Euler class.

description: Satellite communication offers the prospect of service continuity over uncovered and under-covered areas, service ubiquity, and service scalability. However, several challenges must first be addressed to realize these benefits, as the resource management, network control, network security, spectrum management, and energy usage of satellite networks are more challenging than that of terrestrial networks. Meanwhile, artificial intelligence (AI), including machine learning, deep learning, and reinforcement learning, has been steadily growing as a research field and has shown successful results in diverse applications, including wireless communication. In particular, the application of AI to a wide variety of satellite communication aspects have demonstrated excellent potential, including beam-hopping, anti-jamming, network traffic forecasting, channel modeling, telemetry mining, ionospheric scintillation detecting, interference managing, remote sensing, behavior modeling, space-air-ground integrating, and energy managing. This work thus provides a general overview of AI, its diverse sub-fields, and its state-of-the-art algorithms. Several challenges facing diverse aspects of satellite communication systems are then discussed, and their proposed and potential AI-based solutions are presented. Finally, an outlook of field is drawn, and future steps are suggested.

Asymmetric two-output quantum processor in any dimension
Creators: name: Ghiu, Iulia

Year: 2006
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We propose two different implementations of an asymmetric two-output probabilistic quantum processor, which can implement a restricted set of one-qubit operations. One of them is constructed by combining asymmetric telecloning with a quantum gate array. We analyze the efficiency of this processor by evaluating the fidelities between the desired operation and the one generated by the processor and show that the two output states are the same as the ones produced by the optimal universal asymmetric Pauli cloning machine. The schemes require only local operations and classical communication, they have the advantage of transmitting the two output states directly to two spatially separated receivers but they have a success probability of 1/2. We show further that we can perform the same one-qubit operation with unity probability at the cost of using nonlocal operations. We finally generalize the two schemes for D-level systems and find that the local ones are successful with a probability of 1/D and the nonlocal generalized scheme is always successful.

Poisson-bracket formulation of the dynamics of fluids of deformable particles

Year: 2020
Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Using the Poisson bracket method, we derive continuum equations for a fluid of deformable particles in two dimensions. Particle shape is quantified in terms of two continuum fields: an anisotropy density field that captures the deformations of individual particles from regular shapes and a shape tensor density field that quantifies both particle elongation and nematic alignment of elongated shapes. We explicitly consider the example of a dense biological tissue as described by the Vertex model energy, where cell shape has been proposed as a structural order parameter for a liquid-solid transition. The hydrodynamic model of biological tissue proposed here captures the coupling of cell shape to flow, and provides a starting point for modeling the rheology of dense tissue.

The Hague Conference on International Private Law haw negotiated and concluded thw Hague Convention on the law applicable on certain rights in respect of securities held with an intermediary. The Convention adopts the PRIMA ( Plece of the Relevant Intermediary Approach)rule for the determination of the applicable law, interpreting it as the law chosen in the securities agreement between the investor and the relevant intermediary, provided that the latter has some kind of relationship (e.g. office) with the State the law of which is chosen as applicable. I t is noted that the interpretation of PRIMA adopted by the Convention is different from the one adopted by simmilar directives of the European Union, which focus on the location of the relevant account.

description: Over the last few years, running high performance computing applications in the cloud has become feasible. At the same time, GPGPUs are delivering unprecedented performance for HPC applications. Cloud providers thus face the challenge to integrate GPGPUs into their virtualized platforms, which has proven difficult for current virtualization stacks. In this paper, we present LoGV, an approach to virtualize GPGPUs by leveraging protection mechanisms already present in modern hardware. LoGV enables sharing of GPGPUs between VMs as well as VM migration without modifying the host driver or the guest’s CUDA runtime. LoGV allocates resources securely in the hypervisor which then grants applications direct access to these resources, relying on GPGPU hardware features to guarantee mutual protection between applications. Experiments with our prototype have shown an overhead of less than 4% compared to native execution.

description: Star-forming galaxies with nebular HeII emission contain very energetic ionizing sources of radiation, which can be considered as analogs to the major contributors of the reionization of the Universe in early epochs. It is therefore of great importance to provide a reliable absolute scale for the equivalent effective temperature (T*) for these sources. We study a sample of local (z< 0.2) star-forming galaxies showing optical nebular HeII emission using the so-called softness diagrams, involving emission lines of two elements in two consecutive stages of ionization (e.g., [SII]/[SIII] vs. [OII]/[OIII]). We use for the first time the HeI/heII ratio in these diagrams in order to explore the higher range of T* expected in these objects.We build grids of photoionization models covering different black-body temperatures, model cluster atmospheres, and density-bounded geometries to explain the conditions observed in the sample. We verified that the use of the softness diagrams including the emission-line ratio HeI/HeII combined with black-body photoionization models can provide an absolute scale of T* for these objects. The application of a Bayesian-like code indicates T* in the range 50-80 kK for the sample of galaxies, with a mean value higher than 60 kK. The average of these high temperature values can only be reproduced using cluster model populations with nearly metal-free stars, although such ionizing sources cannot explain either the highest T* values, beyond 1 sigma, or the dispersion observed in the softness diagrams. According to our photoionization models, most sample galaxies could be affected to some extent by ionizing photon leaking, presenting a mean photon absorption fraction of 26% or higher depending on the metallicity assumed for the ionizing cluster.

description: We present an analysis of the star formation properties of field galaxies within the local volume out to a recession velocity limit of 3000 km/s. A parent sample of 863 star-forming galaxies is used to calculate a B-band luminosity function. This is then populated with star formation information from a subsample of 327 galaxies, for which we have H alpha imaging, firstly by calibrating a relationship between galaxy B-band luminosity and star formation rate, and secondly by a Monte Carlo simulation of a representative sample of galaxies, in which star formation information is randomly sampled from the observed subset. The total star formation rate density of the local Universe is found to be between 0.016 and 0.023 MSun/yr/cubic Mpc, with the uncertainties being dominated by the internal extinction correction used in converting measured H alpha fluxes to star formation rates. If our internally derived B-band luminosity function is replaced by one from the Sloan Digital Sky Survey blue sequence, the star formation rate densities are approx. 60% of the above values. We also calculate the contribution to the total star formation rate density from galaxies of different luminosities and Hubble T-types. The largest contribution comes from bright galaxies with B absolute mag of approx. -20 mag, and the total contribution from galaxies fainter than -15.5 mag is less than 10%. Almost 60% of the star formation rate density comes from galaxies of types Sb, Sbc or Sc; 9% from galaxies earlier than Sb and 33% from galaxies later than Sc. Finally, 75 - 80% of the total star formation in the local Universe is shown to be occurring in disk regions, defined as being >1 kpc from the centres of galaxies.

description: The three-point amplitude is the key building block in the on-shell approach to scattering amplitudes. We show that the classical objects computed by massive three-point amplitudes in gauge theory and gravity are Newman-Penrose scalars in a split-signature spacetime, where three-point amplitudes can be defined for real kinematics. In fact, the quantum state set up by the particle is a coherent state fully determined by the three-point amplitude due to an eikonal-type exponentiation. Having identified this simplest classical solution from the perspective of scattering amplitudes, we explore the double copy of the Newman-Penrose scalars induced by the traditional double copy of amplitudes, and find that it coincides with the Weyl version of the classical double copy. We also exploit the Kerr-Schild version of the classical double copy to determine the exact spacetime metric in the gravitational case. Finally, we discuss the direct implication of these results for Lorentzian signature via analytic continuation.

description: Mounting debt and a continuing inability to feed their populations have led countries of Sub-Saharan Africa to undertake reform programs to make their economies more market oriented. At the same time, they have sought to protect the food security of their most vulnerable population groups. Kenya, Tanzania, and Zimbabwe are three case studies that represent the common dilemma: how to adhere to long-term economic reform while protecting vulnerable consumer groups from market inefficiencies and price shocks.

description: Earth's continents are characterized by a strong enrichment in long-lived radioactive isotopes. Recent estimates suggest that they contribute to 33\% of the heat released at the surface of the Earth, while occupying less than 1\% of the mantle. This distinctive feature has profound implications for the underlying mantle by impacting its thermal structure and heat transfer. However, the effects of a continental crust enriched in heat-producing elements on the underlying mantle have not yet been systematically investigated. Here, we conduct a preliminary investigation by considering a simplified convective system consisting in a mixed heated fluid where all the internal heating is concentrated in a top layer of thickness $d_{HL}$ (referred to as "heat-blanketed convection"). We perform 24 numerical simulations in 3D Cartesian geometry for four specific set-ups and various values of $d_{HL}$. Our results suggest that the effects of the heated layer strongly depend on its thickness relative to the thickness of the thermal boundary layer ($δ_{TBL}$) in the homogeneous heating case ($d_{HL} = 1.0$). More specifically, for $d_{HL} > δ_{TBL}$, the effects induced by the heated layer are quite modest, while, for $d_{HL} < δ_{TBL}$, the properties of the convective system are strongly altered as $d_{HL}$ decreases. In particular, the surface heat flux and convective vigour are significantly enhanced for very thin heated layers compared to the case $d_{HL} = 1.0$. The vertical distribution of heat producing elements may therefore play a key role on mantle dynamics. For Earth, the presence of continents should however not affect significantly the surface heat flux, and thus the Earth's cooling rate.

description: We present a detailed study of the spectral and temporal properties of the X-ray flares emission of several GRBs. We select a sample of GRBs which X-ray light curve exhibits large amplitude variations with several rebrightenings superposed on the underlying three-segment broken powerlaw that is often seen in Swift GRBs. We try to understand the origin of these fluctuations giving some diagnostic in order to discriminate between refreshed shocks and late internal shocks. For some bursts our time-resolved spectral analysis supports the interpretation of a long-lived central engine, with rebrightenings consistent with energy injection in refreshed shocks as slower shells generated in the central engine prompt phase catch up with the afterglow shock at later times.

description: We wish to understand the reasons for the strong variability of H2O masers in circumstellar shells of late-type stars. We monitored RX Boo and SV Peg in the 22-GHz maser line of water vapour with single-dish telescopes. The monitoring period covered two decades for RX Boo (1987 -- 2007) and 12 years for SV Peg (1990 -- 1995, 2000 -- 2007). In addition, maps were obtained of RX Boo with the Very Large Array over several years. We find that most of the emission in the circumstellar shell of RX Boo is located in an incomplete ring with an inner radius of 91 mas (15 AU). A velocity gradient is found in a NW--SE direction. The maser region can be modelled as a shell with a thickness of 22 AU, which is only partially filled. The gas crossing time is 16.5 years. The ring-like structure and the velocity gradient remained stable for at least 11 years, while the maser line profiles varied strongly. This suggests that the spatial asymmetry is not accidental, so that either the mass loss process or the maser excitation conditions in RX Boo are not spherically symmetric. The strong variability of the maser spectral features is mainly due to incoherent intensity fluctuations of maser emission spots, which have lifetimes of the order of 1 year. We found no correlation between the optical and the maser variability in either star. The variability properties of the SV Peg masers do not differ substantially from those of RX Boo. There were fewer spectral features present, and the range of variations was narrower. The maser was active on the >10-Jy level only 1990 -- 1992 and 2006/2007. At other times the maser was either absent (<1 Jy) or barely detectable.

description: A significant number of those killed in traffic accidents annually refers to pedestrians. most of these accidents occur when a pedestrian is going to pass the street. One of the most hazardous areas for pedestrians crossing the street is midblock crosswalks. These areas are often uncontrolled and there is no separated phase for pedestrian crossing. As a result, using created gaps among vehicles is often the only opportunity for pedestrians to cross the street. This research aims to investigate effective factors on pedestrian gap acceptance at uncontrolled mid-block crosswalks. In this regard, several variables such as individual, environmental, and traffic variables were considered and their related data were extracted by filming the location. from video images, they were analyzed using logit regression model and the behavior After extracting the data of pedestrian while he is crossing the street was modeled as the probabilistic function of pedestrian gap acceptance. The results illustrate that conflict flow rate, the temporal gap among vehicles, and driver yielding in the face of vehicles are the most important effective factors on pedestrian behavior. The other one is that the speed and type of vehicles do not affect the pedestrian's decision about rejecting or accepting the gap. The results also show that individual characteristics such as age and gender of pedestrians do not make a significant relationship with pedestrian gap acceptance.

description: We present a hybrid Brownian dynamics / Monte Carlo algorithm for simulating solutions of highly entangled semiflexible polymers or filaments. The algorithm combines a Brownian dynamics time-stepping approach with an efficient scheme for rejecting moves that cause chains to cross or that lead to excluded volume overlaps. The algorithm allows simulation of the limit of infinitely thin but uncrossable threads, and is suitable for simulating the conditions obtained in experiments on solutions of long actin protein filaments.

description: Ο σκοπός της εργασίας είναι η εξέταση της έννοιας της αναπαράστασης όπως διατυπώνεται στα διηγήματα περί πολιτικής βίας του J. Cortazar και του D. Kis. Τα διηγήματα αυτά διαβάζονται ως πολιτικές μεταμυθοπλασίες, οι οποίες, ακολουθώντας τη δομή αντιπαράθεσης ανάμεσα στα δύο είδη γραφής (ρεαλιστικής/ιστορικής και λογοτεχνικής), εξετάζουν τις θεωρητικές προϋποθέσεις της αναπαράστασης. Σύμφωνα και με τους δύο συγγραφείς, η λογοτεχνική αναπαράσταση, έχοντας συνείδηση της δικής της υλικότητας και των αφηγηματικών της στοιχείων, δηλαδή για το μερίδιο του φαντασιακού και επινοημένου, παρουσιάζεται ως ο πιο γνήσιος τρόπος αναπαράστασης της βίας, καθώς και ως ο μόνος τρόπος αντίστασης στην ιδεολογική καταπίεση.
description: The target of this paper is the examination of the notion of representation as it is exemplified in the short stories on violence by J. Cortazar and D. Kis. I read these stories as political metafictions, which are structured as juxtapositions of realistic/historical vs literary writing, and in this way examine the theoretical postulates of representation. According to both authors, literary representation, self-conscious of its qwn textual and narrative features, i.e of its constructed and invented elements, actually represents the most legitimate mode of representation of political violence, and at the same time the only mode of resistance to ideological oppression.

description: Turbulence is a key process in many fields of astrophysics. Advances in numerical simulations of fluids over the last several decades have revolutionized our understanding of turbulence and related processes such as star formation and cosmic ray propagation. However, data from numerical simulations of astrophysical turbulence are often not made public. We introduce a new simulation-oriented database for the astronomical community: The Catalogue for Astrophysical Turbulence Simulations (CATS), located at www.mhdturbulence.com. CATS includes magnetohydrodynamic (MHD) turbulent box simulation data products generated by the public codes athena++, arepo, enzo, and flash. CATS also includes several synthetic observational data sets, such as turbulent HI data cubes. We also include measured power spectra and 3-point correlation functions from some of these data. We discuss the importance of open source statistical and visualization tools for the analysis of turbulence simulations such as those found in CATS.

description: By following previous work on this subject, we investigate the issue of the instability of the electroweak vacuum against the top loop corrections by performing an accurate analysis of a Higgs-Yukawa model. We find that, when the physical cutoff is properly implemented in the theory, the potential does not exhibit any instability. Moreover, contrary to recent claims, we show that this instability cannot be understood in terms of the very insightful work of Wu and Weinberg on the non-convexity of the one-loop effective potential of a scalar theory. Some of the theoretical and phenomenological consequences of our results are briefly discussed.
