description: We show that the spin-orbit interaction induced by the boundary confining potential causes opposite spin accumulations on the transverse edges in a zonal two-dimensional electron gas in the presence of external longitudinal electric field. While the bias is reversed, the spin polarized direction is also reversed. The intensity of the spin accumulation is proportional to the bias voltage. In contrast to the bulk extrinsic and intrinsic spin Hall effects, the spin accumulation by the confining potential is almost unaffected by impurity and survives even in strong disorder. The result provides a new mechanism to explain the recent experimental data.

description: Cytomixis consists of the migration of chromatin and/or organelles between proximate cells through intercellular channels. Cytomixis has been detected in 10 taxa belonging to seven families from northwestern Argentina (NWA). The aim of this work was to report the presence of cytomixis in different species, genera and families of angiosperms from NWA. Plant material was collected from different localities. Floral buds were fixed and stained using classical cytogenetic techniques. Cytomixis was observed in both meiotic divisions and was characterized by the connection and passage of substance between two or more cells. Meiotic irregularities, such as agglutinated chromosomes, lagging chromosomes, the formation of bridges, micronuclei, pyknosis were observed in the studied taxa which resulted into the formation of monads, dyads, pentads, and hexads during microsporogenesis. In one of the species, Piper hieronymi, formation of unreduced 2 n pollen grains was also recorded. In this paper, we also provided the lists of 84 families of angiosperms where the phenomenon of cytomixis has been reported so far in the literature. The current paper adds some families and genera where the phenomenon of cytomixis has been reported for the first time.

description: We investigate the vibrational stability and the electronic structure of the proposed icosahedral fullerene-like cage structure of B80 [Szwacki, Sadrzadeh, and Yakobson, Phys. Rev. Lett. {\bf 98}, 166804 (2007)] by an all electron density functional theory using polarized Gaussian basis functions containing 41 basis functions per atom. The vibrational analysis of B$_{80}$ indicates that the icosahedral structure is vibrationally unstable with 7 imaginary frequencies. The equilibrium structure has $T_h$ symmetry and a {\em smaller} gap of 0.96 eV between the highest occupied and lowest unoccupied molecular orbital energy levels compared to the icosahedral structure. The static dipole polarizability of B$_{80}$ cage is 149 \AAA and the first ionization energy is 6.4 eV. The B$_{80}$ cage has rather large electron affinity of 3 eV making it useful candidate as electron acceptor if it is synthesized. The infra-red and Raman spectra of the highly symmetric structure are characterized by a few absorption peaks.

description: Simulation is an attractive alternative for language inclusion for automata as it is an under-approximation of language inclusion, but usually has much lower complexity. For non-deterministic automata, while language inclusion is PSPACE-complete, simulation can be computed in polynomial time. Simulation has also been extended in two orthogonal directions, namely, (1) fair simulation, for simulation over specified set of infinite runs; and (2) quantitative simulation, for simulation between weighted automata. Again, while fair trace inclusion is PSPACE-complete, fair simulation can be computed in polynomial time. For weighted automata, the (quantitative) language inclusion problem is undecidable for mean-payoff automata and the decidability is open for discounted-sum automata, whereas the (quantitative) simulation reduce to mean-payoff games and discounted-sum games, which admit pseudo-polynomial time algorithms. In this work, we study (quantitative) simulation for weighted automata with Büchi acceptance conditions, i.e., we generalize fair simulation from non-weighted automata to weighted automata. We show that imposing Büchi acceptance conditions on weighted automata changes many fundamental properties of the simulation games. For example, whereas for mean-payoff and discounted-sum games, the players do not need memory to play optimally; we show in contrast that for simulation games with Büchi acceptance conditions, (i)for mean-payoff objectives, optimal strategies for both players require infinite memory in general, and (ii) for discounted-sum objectives, optimal strategies need not exist for both players. While the simulation games with Büchi acceptance conditions are more complicated (e.g., due to infinite-memory requirements for mean-payoff objectives) as compared to their counterpart without Büchi acceptance conditions, we still present pseudo-polynomial time algorithms to solve simulation games with Büchi acceptance conditions for both weighted mean-payoff and weighted discounted-sum automata.

description: We present SoFiA 2, the fully automated 3D source finding pipeline for the WALLABY extragalactic HI survey with the Australian SKA Pathfinder (ASKAP). SoFiA 2 is a reimplementation of parts of the original SoFiA pipeline in the C programming language and makes use of OpenMP for multi-threading of the most time-critical algorithms. In addition, we have developed a parallel framework called SoFiA-X that allows the processing of large data cubes to be split across multiple computing nodes. As a result of these efforts, SoFiA 2 is substantially faster and comes with a much reduced memory footprint compared to its predecessor, thus allowing the large WALLABY data volumes of hundreds of gigabytes of imaging data per epoch to be processed in real-time. The source code has been made publicly available to the entire community under an open-source licence. Performance tests using mock galaxies injected into genuine ASKAP data suggest that in the absence of significant imaging artefacts SoFiA 2 is capable of achieving near-100% completeness and reliability above an integrated signal-to-noise ratio of about 5-6. We also demonstrate that SoFiA 2 generally recovers the location, integrated flux and w20 line width of galaxies with high accuracy. Other parameters, including the peak flux density and w50 line width, are more strongly biased due to the influence of the noise on the measurement. In addition, very faint galaxies below an integrated signal-to-noise ratio of about 10 may get broken up into multiple components, thus requiring a strategy to identify fragmented sources and ensure that they do not affect the integrity of any scientific analysis based on the SoFiA 2 output.

Результаты. Установлено, что наиболее часто госпитализация в стационар требовалась пациентам с БА (75,33%), по сравнению с больными АД (24,67%) (р = 0,02). Кроме того, БА статистически значимо чаще страдали дети младшего школьного возраста (87,65%) и подростки (91,47%), тогда как АД - пациенты грудного возраста (89,43%). Среди больных преобладают лица мужского пола (60,51%). Максимальная частота обострений БА отмечается с марта по октябрь и снижается в зимние месяцы. В то же время среди детей с АД значительное повышение частоты обращений за стационарной помощью отмечалось в начале года с последующим снижением в осенне-зимний период. Заключение. Мониторинг частоты обращений детей с аллергопатологией позволяет выявить не только возрастно-половые особенности пациентов, но и прогнозировать пики обострений заболеваемости у них.

description: We study realizations of spirals and skyrmions in two-dimensional antiferromagnets with a triangular lattice on an inversion-symmetry-breaking substrate. As a possible material realization, we investigate the adsorption of transition-metal atoms (Cr, Mn, Fe, or Co) on a monolayer of MoS$_2$, WS$_2$, or WSe$_2$ and obtain the exchange, anisotropy, and Dzyaloshinskii-Moriya interaction parameters using first-principles calculations. Using energy minimization and parallel-tempering Monte-Carlo simulations, we determine the magnetic phase diagrams for a wide range of interaction parameters. We find that skyrmion lattices can appear even with weak Dzyaloshinskii-Moriya interactions, but their stability is hindered by magnetic anisotropy. However, a weak easy plane magnetic anisotropy can be beneficial for stabilizing the skyrmion phase. Our results suggest that Cr$/$MoS$_2$, Fe$/$MoS$_2$, and Fe$/$WSe$_2$ interfaces can host spin spirals formed from the 120$^{\circ}$ antiferromagnetic states. Our results further suggests that for other interfaces, such as Fe$/$MoS$_2$, the Dzyaloshinskii-Moriya interaction is strong enough to drive the system into a three-sublattice skyrmion lattice in the presence of experimentally feasible external magnetic field.

description: We report Brownian dynamics simulation of the out-of-equilibrium dynamics (aging) in a colloidal suspension composed of rigid charged disks, one possible model for Laponite, a synthetic clay deeply investigated in the last few years by means of various experimental techniques. At variance with previous numerical investigations, mainly focusing on static structure and equilibrium dynamics, we explore the out-of-equilibrium aging dynamics. We analyze the wave-vector and waiting time dependence of the dynamics, focusing on the single-particle and collective density fluctuations (intermediate scattering functions), the mean squared displacement and the rotational dynamics. Our findings confirm the complexity of the out-of-equilibrium dynamical behavior of this class of colloidal suspensions and suggest that an arrested disordered state driven by a repulsive Yukawa potential, i.e., a Wigner glass can be observed in this model.

description: This second paper on the revision of the taxonomic identity of several Brachysira species in Europe deals with Brachysira styriaca (Grunow) R.Ross and B. zellensis (Grunow) Round & D.G.Mann. Both species were described by Grunow based on material from Lake Erlauf (Lower Austria and Styria, Austria). Analysis of type material, additional historic and modern samples showed that most populations of B. styriaca from northern Europe belong to a different taxon. This was already described 70 years ago by Cleve-Euler as Anomoeoneis decipiens A.Cleve and is newly recombined here as Brachysira decipiens (A.Cleve) Van de Vijver & Kusber comb. nov. Brachysira decipiens and B. styriaca can be differentiated based on several morphological and distinct ecological preferences. Brachysira styriaca is typically found in calcium-bicarbonate, oligotrophic, alkaline lakes, whereas B. decipiens prefers acid environments. Brachysira rylandsiana Van de Vijver, D.M.Williams & Ector, sp. nov. is split from Brachysira zellensis based on the parallel valve margins, cuneately rounded apices, and several smaller, ultrastructural details. All species are illustrated with both LM and SEM observations. Their ecological preferences are derived from the accompanying diatom flora in the different investigated samples and the literature.

description: Recent years have bore witness to the proliferation of distributed filtering techniques, where a collection of agents communicating over an ad-hoc network aim to collaboratively estimate and track the state of a system. These techniques form the enabling technology of modern multi-agent systems and have gained great importance in the engineering community. Although most distributed filtering techniques come with a set of stability and convergence criteria, the conditions imposed are found to be unnecessarily restrictive. The paradigm of stability and convergence in distributed filtering is revised in this manuscript. Accordingly, a general distributed filter is constructed and its estimation error dynamics is formulated. The conducted analysis demonstrates that conditions for achieving stable filtering operations are the same as those required in the centralized filtering setting. Finally, the concepts are demonstrated in a Kalman filtering framework and validated using simulation examples.
A Mass Function Constraint on Extrasolar Giant Planet Evaporation Rates

description: The observed mass function for all known extrasolar giant planets (EGPs) varies approximately as M^{-1} for mass M between 0.2 Jupiter masses (M_J) and 5 M_J. In order to study evaporation effects for highly-irradiated EGPs in this mass range, we have constructed an observational mass function for a subset of EGPs in the same mass range but with orbital radii <0.07 AU. Surprisingly, the mass function for such highly-irradiated EGPs agrees quantitatively with the M^{-1} law, implying that the mass function for EGPs is preserved despite migration to small orbital radii. Unless there is a remarkable compensation of mass-dependent orbital migration for mass-dependent evaporation, this result places a constraint on orbital migration models and rules out the most extreme mass loss rates in the literature. A theory that predicts more moderate mass loss gives a mass function that is closer to observed statistics but still disagrees for M < 1 M_J.

description: Non-line-of-sight (NLOS) imaging enables monitoring around corners and is promising for diverse applications. The resolution of transient NLOS imaging is limited to a centimeter scale, mainly by the temporal resolution of the detectors. Here, we construct an up-conversion single-photon detector with a high temporal resolution of ~1.4 ps and a low noise count rate of 5 counts per second (cps). Notably, the detector operates at room temperature, near-infrared wavelength. Using this detector, we demonstrate high-resolution and low-noise NLOS imaging. Our system can provide a 180 μm axial resolution and a 2 mm lateral resolution, which is more than one order of magnitude better than that in previous experiments. These results open avenues for high-resolution NLOS imaging techniques in relevant applications.

description: Cross-section and analyzing power data from (p,p') scattering to the 6- states at 11.58 and 14.35 MeV in 28Si, taken with energies of 80, 100, 134, and 180 MeV protons, have been analyzed using a distorted wave approximation with microscopically defined wave functions. The results, taken in conjunction with an analysis of an M6 electron scattering form factor, suggest that the two states exhaust respectively, ~50% and ~60% of the strengths of isoscalar and isovector particle-hole excitations from the ground state. The energy variation of data also suggests that the non-central components of the effective interactions at 80 and 100 MeV may need to be enhanced.

Two investigations in molecular pathophysiology
Creators: name: Orban, Paul C.
Publisher: name: University of British Columbia
Year: 2008

description: This thesis is in two discrete parts. The first part deals with the mechanism of auto-stimulatory growth in the pathogenesis of malignant neoplasia. Experiments were undertaken to investigate the question of whether antagonism of growth-factor activity can lead to the death of the cells of a murine model of auto-stimulatory leukemia. Although many previous workers have examined the ability of growth-factor antagonists to inhibit the growth of the cells of human leukemias and of animal leukemia models, none have documented the complete blockage of growth, and none have documented the death of such cell populations. A model of auto-stimulatory leukemia was generated by transfecting a mouse IL-2-dependent cell line with vectors designed to cause expression of IL-2 in these cells. One series of clones was derived which grew in the absence of exogenous IL-2, and produced tumours in syngeneic mice. Cells of these clones produced very small amounts of IL-2, but their growth was not completely inhibitable by antibodies to IL-2 or the IL-2 receptor. Another clone was derived, which produced no detectable IL-2, but grew independently of exogenous IL-2. The growth of cells of this clone was completely inhibited by antibody, and death of the cells resulted. The experiments described here represent the first demonstration that antibody antagonists of the growth factor can induce the death of cells that grow by auto-stimulatory mechanisms. They support the hope that cytokine antagonists may find use as therapeutic reagents in the treatment of auto-stimulatory neoplasms. The second part of the thesis presents a new technique in gene targetting, which has broad applications in the study of gene function. Using a bacterial recombinase under the control of a tissue-specific developmentally regulated promoter, transgenic animals were derived, in which a target gene was deleted in thymocytes and their daughter cells, but no other tissues. This technique circumvents the impediment embryonic lethality may present in some gene deletion experiments, and allows questions of tissue-specifc function of genes in pathogenesis and normal development to be addressed.

description: When two solids at different temperatures are separated by a vacuum gap they relax toward their equilibrium state by exchanging heat either by radiation, phonon or electron tunneling, depending on their separation distance and on the nature of materials. The interplay between this exchange of energy and its spreading through each solid entirely drives the relaxation dynamics. Here we highlight a significant slowing down of this process in the extreme near-field regime at distances where the heat flux exchanged between the two solids is comparable or even dominates over the flux carried by conduction inside each solid. This mechanism, leading to a strong effective increase of the system thermal inertia, should play an important role in the temporal evolution of thermal state of interacting solids systems at nanometric and subnanometric scales.

description: We developed a statistical method for removing unwanted variation, including batch effects from single-cell RNA-seq data. The method is a generalized linear model (GLM) version of RUV-4 method and uses iterative re-weighted least squares (IRLS) to estimate matrix of unwanted variation while maintaining mean-variance relationship of count data using Negative Binomial regression. We showed that unlike other methods for normalizing scRNA-seq data, our method keeps the type I error rate well.

description: It is examined whether mediation is a suitable alternative dispute resolution mechanism for civil law medical liability cases. The first part of the thesis refers to the institution of mediation, which was introduced in Greece by enacting Law 3898/2010 and the second part examines whether it is possible for mediation to play an important role in the resolution of cases of civil law medical liability. After having examined both the advantages and disadvantages of mediation in these specific cases the thesis concludes to de lege ferenda solutions for the future development of mediation, so that it is an appropriate alternative dispute resolution mechanism for civil law medical liability cases.
Zero-bias tunneling anomaly in a clean 2D electron gas caused by smooth density variations

description: We show that smooth variations, δn({\bf r}), of the local electron concentration in a clean 2D electron gas give rise to a zero-bias anomaly in the tunnel density of states, ν(ω), even in the absence of scatterers, and thus, without the Friedel oscillations. The energy width, ω_0, of the anomaly scales with the magnitude, δn, and characteristic spatial extent, D, of the fluctuations as (δn/D)^{2/3}, while the relative magnitude δν/νscales as (δn/D). With increasing ω, the averaged δνoscillates with ω. We demonstrate that the origin of the anomaly is a weak curving of the classical electron trajectories due to the smooth inhomogeneity of the gas. This curving suppresses the corrections to the electron self-energy which come from the virtual processes involving two electron-hole pairs

description: Outbursts of young stellar objects occur when the mass accretion rate suddenly increases. However, such outbursts are difficult to detect for deeply embedded protostars due to their thick envelope and the rarity of outbursts. The near-IR spectroscopy is a useful tool to identify ongoing outburst candidates by the characteristic absorption features that indicate a disk origin. However, without high-resolution spectroscopy, the spectra of outburst candidates can be confused with the late-type stars since they have similar spectral features. For the protostar IRAS 16316-1540, the near-IR spectrum has line equivalent widths that are consistent with M-dwarf photospheres. However, our high-resolution IGRINS spectra reveal that the absorption lines have boxy and/or double-peaked profiles, as expected from a disk and not the star. The continuum emission source is likely the hot, optically thick disk, heated by viscous accretion. The projected disk rotation velocity of 41$\pm$5 km s$^{-1}$ corresponds to $\sim 0.1$ AU. Based on the result, we suggest IRAS 16316-1540 as an ongoing outburst candidate. Viscous heating of disks is usually interpreted as evidence for ongoing bursts, which may be more common than previously estimated from low-resolution near-IR spectra.

description: We present Submillimeter Array (SMA) observations of several deuterated species in the disk around the classical T Tauri star TW Hydrae at arcsecond scales, including detections of the DCN J=3-2 and DCO+ J=3-2 lines, and upper limits to the HDO 3(1,2)-2(2,1), ortho-H2D+ 1(1,0)-1(1,1) and para-D2H+ 1(1,0)-1(0,1) transitions. We also present observations of the HCN J=3-2, HCO+ J=3-2 and H13CO+ J=4-3 lines for comparison with their deuterated isotopologues. We constrain the radial and vertical distributions of various species in the disk by fitting the data using a model where the molecular emission from an irradiated accretion disk is sampled with a 2D Monte Carlo radiative transfer code. We find that the distribution of DCO+ differs markedly from that of HCO+. The D/H ratios inferred change by at least one order of magnitude (0.01 to 0.1) for radii <30 AU to >70 AU and there is a rapid falloff of the abundance of DCO+ at radii larger than 90 AU. Using a simple analytical chemical model, we constrain the degree of ionization, x(e-)=n(e-)/n(H2), to be ~10^-7 in the disk layer(s) where these molecules are present. Provided the distribution of DCN follows that of HCN, the ratio of DCN to HCN is determined to be 1.7\pm0.5 \times 10^-2; however, this ratio is very sensitive to the poorly constrained vertical distribution of HCN. The resolved radial distribution of DCO+ indicates that {\it in situ} deuterium fractionation remains active within the TW Hydrae disk and must be considered in the molecular evolution of circumstellar accretion disks.

description: O εγκέφαλος είναι το πιο μυστήριο όργανο του ανθρώπινου σώματος. Η ενδελεχής εξερεύνηση της ακριβούς ανατομίας και λειτουργίας του καθυστέρησε για αιώνες, εξαιτίας της περίπλοκης κατασκευής και της μοναδικής βιολογίας του. H ανάδυση των νευροεπιστημών, ιδιαιτέρως μετά την ανάπτυξη των νέων νευροαπεικονιστικών τεχνικών και της νευροδιέγερσης, υπόσχεται σημαντικές εξελίξεις στο πεδίο της ιατρικής και της έρευνας. Αν και την ίδια στιγμή έχει δημιουργήσει αρκετά κοινωνικά, νομικά και ηθικά διλήμματα, διαφορετικά από αυτά που αντιμετώπιζε η παραδοσιακή βιοηθική έως τώρα. Αυτό οφείλεται στην τρέχουσα, αλλά και στην πιθανή μελλοντική χρήση των νευροεπιστημών σε ένα μεγάλο φάσμα της ανθρώπινης δραστηριότητας που εκτείνεται από τη νομική, την οικονομία, το marketing και την πολιτική έως το στρατό, τα εργασιακά περιβάλλοντα και πολλούς άλλους τομείς. Γι αυτό η νευροηθική, ένα νέο πεδίο της βιοηθικής αναπτύσσεται σταδιακά σε παγκόσμιο επίπεδο. Νευροεπιστήμονες και επιστήμονες που ασχολούνται με τη νευροηθική καλούνται να προσδιορίσουν και να αναδείξουν τους πιθανούς κινδύνους από τη χρήση των νευροεπιστημών και να προτείνουν ένα πλαίσιο για ασφαλέστερη χρήση σύμφωνο με τις ανθρώπινες αξίες.
description: Brain has been the most mysterious organ of the human body. The thorough exploration of its exact anatomy and function has delayed for centuries due to its complicated construction and unique biology. The emergence of neurosciences, especially after the development of new neuroimaging techniques and neurostimulation, promises great progressions in the realms of medicine and research. Although at the same time it has created many social, legal and ethical dilemmas, different from those that traditional bioethics have faced until recently. This happens due to their current and potential future use of neurosciences in a wide spectrum of human activities ranging from medicine, law, economics, marketing and politics, to military services, work places and many other realms. That s why neuroethics, a relatively new branch of bioethics is being expanded progressively worldwide. Neuroscientists and neuroethicists are called to define and point out the potential risks from this use and suggest the frame for moral and safe use of neurosciences.

description: We aim to unravel the interior mixing profile of the pulsating eclipsing binary KIC9850387 by comparing its dynamical parameters and the parameters derived through a combination of evolutionary and asteroseismic modelling. We created a grid of stellar evolutionary models using the stellar evolutionary code \textsc{mesa} and performed an isochrone-cloud (isocloud) based evolutionary modelling of the system. We then generated a grid of pulsational models using the stellar pulsation code \textsc{gyre} based on the age constraints from the evolutionary modelling. Finally, we performed asteroseismic modelling of the observed $\ell=1$ and $\ell=2$ period-spacing patterns, utilising different combinations of observational constraints, merit functions, and asteroseismic observables to obtain strong constraints on the interior properties of the primary star. Through a combination of asteroseismic modelling and dynamical constraints, we found that the system comprises two main-sequence components at an age of $1.2\pm0.1$ Gyr. We also observed that asteroseismic modelling provided stronger constraints on the interior properties than evolutionary modelling. Overall, we found high levels of interior mixing and posited that this is a result of intrinsic non-tidal mixing mechanisms due to a similar observed behaviour in single stars. We investigated the high-frequency regime of KIC9850387 and found evidence of the surface effect as well as rotational splitting in the form of a prograde-retrograde dipole g$_{1}$ mode doublet with a missing zonal mode. We find that the dynamical parameters and the parameters extracted from the asteroseismic modelling of period-spacing patterns are only barely compliant, reinforcing the need for homogeneous analyses of samples of pulsating eclipsing binaries that aim to calibrating interior mixing profiles.

description: The paper addresses the problem of a a semi-infinite plane crack along the interface between two 3D isotropic half-spaces. Two methods of solution have been considered in the past: Lazarus and Leblond (1998) applied the "special" method by Bueckner (1987) and found the expression of the variation of the stress intensity factors for a wavy crack without solving the complete elasticity problem; their solution is expressed in terms of the physical variables, and it involves five constants whose analytical representation was unknown; on the other hand the "general" solution to the problem has been recently addressed by Bercial-Velez et al. (2005), using a Wiener-Hopf analysis and singular asymptotics near the crack front. The main goal of the present paper is to complete the solution to the problem by providing the connection between the two methods. This is done by constructing an integral representation for the Lazarus-Leblond's weight functions and by deriving the closed form representations of the Lazarus-Leblond's constants.

description: We put forward an alternative approach to the SLOCC classification of entanglement states of three-qubit and four-qubit systems. By directly solving matrix equations, we obtain the relations satisfied by the amplitudes of states. The relations are readily tested since in them only addition, subtraction and multiplication occur.

description: As a novel layered noble metal dichalcogenide material, palladium diselenide (PdSe2) has attracted wide interest due to its excellent optical and electronic properties. In this work, a strong third-order nonlinear optical response of 2D PdSe2 films is reported. We conduct both open aperture (OA) and closed-aperture (CA) Z scan measurements with a femtosecond pulsed laser at 800 nm to investigate the nonlinear absorption and nonlinear refraction, respectively. In the OA experiment, we observe optical limiting behaviour originating from large two photo absorption (TPA) in the PdSe2 film of \b{eta} = 3.26 x 10-8 m/W. In the CA experiment, we measure a peak-valley response corresponding to a large and negative Kerr nonlinearity of n2 = -1.33 x 10-15 m2/W, two orders of magnitude larger than bulk silicon. In addition, the variation of n2 as a function of laser intensity is also characterized, with n2 decreasing in magnitude when increasing incident laser intensity, becoming saturated at n2 = -9.96 x 10-16 m2/W at high intensities. Our results show that the extraordinary third order nonlinear optical properties of PdSe2 have strong potential for high-performance nonlinear photonic devices.

description: Transfer of angular momentum from a spin-polarized current to a ferromagnet provides an efficient means to control the dynamics of nanomagnets. A peculiar consequence of this spin-torque, the ability to induce persistent oscillations of a nanomagnet by applying a dc current, has previously been reported only for spatially uniform nanomagnets. Here we demonstrate that a quintessentially nonuniform magnetic structure, a magnetic vortex, isolated within a nanoscale spin valve structure, can be excited into persistent microwave-frequency oscillations by a spin-polarized dc current. Comparison to micromagnetic simulations leads to identification of the oscillations with a precession of the vortex core. The oscillations, which can be obtained in essentially zero magnetic field, exhibit linewidths that can be narrower than 300 kHz, making these highly compact spin-torque vortex oscillator devices potential candidates for microwave signal-processing applications, and a powerful new tool for fundamental studies of vortex dynamics in magnetic nanostructures.

description: Στην παρούσα εργασία εξετάζεται η έννοια της φαντασίας, όπως αυτή απαντάται στο έργο του Σπινόζα. Οι λειτουργίες της φαντασίας είναι τόσο γνωστικές όσο και συναισθηματικές και συνδράμουν στην αυτό-συνείδηση και τη γνώση. Όταν η φαντασία γίνεται από ατομική συλλογική δημιουργεί ουτοπικά σχέδια και αυτά κινητοποιούν τις μάζες προς την κοινωνική απελευθέρωση. Εξετάζοντας της ουτοπικές αναφορές μέχρι το Μαρξ, αναζητούμε ένα νέο ουτοπικό σχέδιο που λαμβάνει υπόψη τα ανθρώπινα πάθη αλλά και τις ταξικές συγκρούσεις, με γνώμονα τις σημερινές συνθήκες.
description: In this essay we examine the concept of imagination as it is observed in Spinoza's work. The function of imagination is both cognitive and emotional and it contributes to self-consciousness and knowledge. When imagination turns from something personal to something collective it can trigger utopian theories and visions which in turn can motivate the masses and lead to a social liberation. As we are examining the references to utopia up until Marx we are after a new plan that takes into account the concepts of utopia, emotions and class conflict under the current socioeconomic circumstances.
