description: The turbulent pumping effect corresponds to the transport of magnetic flux due to the presence of density and turbulence gradients in convectively unstable layers. In the induction equation it appears as an advective term and for this reason it is expected to be important in the solar and stellar dynamo processes. In this work, we have explored the effects of the turbulent pumping in a flux-dominated Babcock-Leighton solar dynamo model with a solar-like rotation law. The results reveal the importance of the pumping mechanism for solving current limitations in mean field dynamo modeling such as the storage of the magnetic flux and the latitudinal distribution of the sunspots. In the case that a meridional flow is assumed to be present only in the upper part of the convective zone, it is the full turbulent pumping that regulates both the period of the solar cycle and the latitudinal distribution of the sunspots activity.

Direct reconstruction of spherical harmonics from interferometer observations of the CMB polarization
Creators: name: Kim, Jaiseung
Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Interferometric observation of the CMB polarization can be expressed as a linear sum of spherical harmonic coefficients $a_{\pm 2,lm}$ of the CMB polarization. The linear weight for $a_{\pm 2,lm}$ depends on the observational configuration such as antenna pointing, baseline orientation, and spherical harmonic number $l,m$. Since an interferometer is sensitive over a finite range of multipoles, $a_{\pm 2,lm}$ in the range can be determined by fitting $a_{\pm 2,lm}$ for visibilities of various observational configurations. The formalism presented in this paper enables the determination of $a_{\pm 2,lm}$ directly from spherical harmonic spaces without spherical harmonic transformation of pixellized maps. The result of its application to a simulated observation is presented with the formalism.

description: Magnetic trapping potentials for atoms on atom chips are determined by the current flow in the chip wires. By modifying the shape of the conductor we can realize specialized current flow patterns and therefore micro-design the trapping potentials. We have demonstrated this by nano-machining an atom chip using the focused ion beam technique. We built a trap, a barrier and using a BEC as a probe we showed that by polishing the conductor edge the potential roughness on the selected wire can be reduced. Furthermore we give different other designs and discuss the creation of a 1D magnetic lattice on an atom chip.

description: Scattering observables can be computed in lattice field theory by measuring the volume dependence of energy levels of two particle states. The dominant volume dependence, proportional to inverse powers of the volume, is determined by the phase shifts. This universal relation (\Lu's formula) between energy levels and phase shifts is distorted by corrections which, in the large volume limit, are exponentially suppressed. They may be sizable, however, for the volumes used in practice and they set a limit on how small the lattice can be in these studies. We estimate these corrections, mostly in the case of two nucleons. Qualitatively, we find that the exponentially suppressed corrections are proportional to the {\it square} of the potential (or to terms suppressed in the chiral expansion) and the effect due to pions going ``around the world'' vanishes. Quantitatively, the size of the lattice should be greater than $\approx(5 {fm})^3$ in order to keep finite volume corrections to the phase less than $1^\circ$ for realistic pion mass.

description: The general features of quark and pion condensation in dense quark matter with flavor asymmetry have been considered at finite temperature in the presence of a chromomagnetic background field modelling the gluon condensate. In particular, pion condensation in the case of a constant abelian chromomagnetic field and zero temperature has been studied both analytically and numerically. Under the influence of the chromomagnetic background field the effective potential of the system is found to have a global minimum for a finite pion condensate even for small values of the effective quark coupling constant. In the strong field limit, an effective dimensional reduction has been found to take place.

description: In strong uniform magnetic field, the vacuum Non-Commutative Plane (NCP) caused by the lowest Landau level(LLL) effect and the QED with NCP (QED-NCP) are studied. Being similar to the theory of Quantum Hall effect, an effective filling factor $f(B)$ is introduced to character the possibility that the electrons stays on LLL. The backward Compton scattering amplitudes of QED-NCP are derived, and the differential cross sections for the process with polarized initial electrons and photons are calculated. The existing Spring-8's data has been analyzed primitively and some hints for QED-NCP effects are shown. We propose to precisely measure the differential cross sections of the backward Compton scattering in perpendicular magnetic field experimentally, which may lead to reveal the effects of QED-NCP.

Deterministic excitable media under Poisson drive: power law responses, spiral waves and dynamic range

Subjects: subject: Neurons and Cognition (q-bio.NC)

description: When each site of a spatially extended excitable medium is independently driven by a Poisson stimulus with rate h, the interplay between creation and annihilation of excitable waves leads to an average activity F. It has recently been suggested that in the low-stimulus regime (h ~ 0) the response function F(h) of hypercubic deterministic systems behaves as a power law, F ~ h^m. Moreover the response exponent m has been predicted to depend only on the dimensionality d of the lattice, m = 1/(1+d) [T. Ohta and T. Yoshimura, Physica D 205, 189 (2005)]. In order to test this prediction, we study the response function of excitable lattices modeled by either coupled Morris-Lecar equations or Greenberg-Hastings cellular automata. We show that the prediction is verified in our model systems for d = 1, 2, and 3, provided that a minimum set of conditions is satisfied. Under these conditions, the dynamic range - which measures the range of stimulus intensities that can be coded by the network activity - increases with the dimensionality d of the network. The power law scenario breaks down, however, if the system can exhibit self-sustained activity (spiral waves). In this case, we recover a scenario that is common to probabilistic excitable media: as a function of the conductance coupling G among the excitable elements, the dynamic range is maximized precisely at the critical value G_c above which self-sustained activity becomes stable. We discuss the implications of these results in the context of neural coding.

Στην εισαγωγή περιγράφεται ιστορικό υπόβαθρο των δύο μυθιστορημάτων την περίοδο της Κατοχής στην Θεσσαλονίκη με φόντο τα γεγονότα σε όλη την Ελλάδα. Το πρώτο κεφάλαιο παρουσιάζει πώς η Θεσσαλονίκη αναδύεται ως τοπίος μνήμης στα δύο μυθιστορήματα χρησιμοποιώντας τις θεωρίες μνήμης του Πιέρ Νορά και την Α.Άσμαν καθώς και τις θεωρίες της πολιτισμικής μνήμης. Το δεύτερο κεφάλαιο εστιάζεται στο τράυμα Ολοκαυτώματος στα δύο έργα και την εικόνα των Ναζί και τη βία τους εναντίων των Ελλήνο-Εβραίων αναλύοντας τους κεντρικούς χαρακτήρες των μυθιστορημάτων και τις στρατηγικές της αντίστασης τους στη ναζιστική βία και της επιβίωσης. Σε αυτό το κεφάλαιο εφαρμόζονται οι θεωρίες της πολιτισμικής μνήμης και οι θεωρίες τραύματος της Κ.Κάρουθ. Το τρίτο κεφάλαιο είναι αφιερωμένο στο πώς οι θεωρίες της πολιτισμικής μνήμης στηρίζουν τους τρόπους διαπραγμάτευσης Ολοκαυτώματος στα δύο βιβλία και γιατί αυτές είναι σημαντικές στο πλαίσιο της ενιαίας Ευρωπαϊκής μνήμης και πολιτικής σήμερα.
description: The Master’s thesis is describing the ways in which the cultural memory of Holocaust is being constructed in two literary works about the Holocaust of Jews of Thessaloniki during the Second World War.The introduction describes the historical background of the two narratives focusing on Thessaloniki and touching upon the war-period events in Greece in the background. The first chapter attempts to explain how Thessaloniki becomes a place of memory in both texts taking into account theoretical approaches to memory cultures and literatures by P. Nora, A. Assmann and other scholars. The second chapter focuses on the traumatic experiences of Holocaust as they are presented in the two works and the picture of Nazi and their violence against the Greek Jewry by analysing the main characters of the literary texts and their resistance and survival strategies. This chapter also uses trauma theories by such scholars as Cathy Carouth. The third chapter is responding to the question of how the cultural memory theories support the ways of negotiating Holocaust in both works and why they are important in the framework of the common European remembrance policy today.

description: We theoretically investigate electron-hole recollisions in high-harmonic generation (HHG) in band-gap solids irradiated by linearly and elliptically polarized drivers. We find that in many cases the emitted harmonics do not originate in electron-hole pairs created at the minimum band gap, where the tunneling probability is maximized, but rather in pairs created across an extended region of the Brillouin zone (BZ). In these situations, the analogy to gas-phase HHG in terms of the short- and long-trajectory categorizations is inadequate. Our analysis methodology comprises three complementary levels of theory: the numerical solutions to the semiconductor Bloch equations, an extended semiclassical recollision model, and a quantum wave packet approach. We apply this methodology to two general material types with representative band structures: a bulk system and a hexagonal monolayer system. In the bulk, the interband harmonics generated using elliptically-polarized drivers are found to originate not from tunneling at the minimum band gap $Γ$, but from regions away from it. In the monolayer system driven by linearly-polarized pulses, tunneling regions near different symmetry points in the BZ lead to distinct harmonic energies and emission profiles. We show that the imperfect recollisions, where an electron-hole pair recollide while being spatially separated, are important in both bulk and monolayer materials. The excellent agreement between our three levels of theory highlights and characterizes the complexity behind the HHG emission dynamics in solids, and expands on the notion of interband HHG as always originating in trajectories tunnelled at the minimum band gap. Our work furthers the fundamental understanding of HHG in periodic systems and will benefit the future design of experiments.

description: For studying the interplay of dipolar interaction and anisotropy energy in systems of ultrafine magnetic particles we consider simple cubic systems of magnetic dipoles with anisotropy axes pointing into the $z$-direction. Using Monte Carlo simulations we study the magnetic relaxation from several initial states. We show explicitely that, due to the combined influence of anisotropy energy and dipole interaction, magnetic chains are formed along the $z$-direction that organize themselves in frozen metastable domains of columnar antiferromagnetic order. We show that the domains depend explicitely on the history and relax only at extremely large time scales towards the ordered state. We consider this as an indication for the appearence of frozen metastable states also in real sytems, where the dipoles are located in a liquid-like fashion and the anisotropy axes point into random directions.

Capacity of a Class of Deterministic Relay Channels

Year: 2006
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: The capacity of a class of deterministic relay channels with the transmitter input X, the receiver output Y, the relay output Y_1 = f(X, Y), and a separate communication link from the relay to the receiver with capacity R_0, is shown to be C(R_0) = \max_{p(x)} \min \{I(X;Y)+R_0, I(X;Y, Y_1) \}. Thus every bit from the relay is worth exactly one bit to the receiver. Two alternative coding schemes are presented that achieve this capacity. The first scheme, ``hash-and-forward'', is based on a simple yet novel use of random binning on the space of relay outputs, while the second scheme uses the usual ``compress-and-forward''. In fact, these two schemes can be combined together to give a class of optimal coding schemes. As a corollary, this relay capacity result confirms a conjecture by Ahlswede and Han on the capacity of a channel with rate-limited state information at the decoder in the special case when the channel state is recoverable from the channel input and the output.

description: We report a supernova discovery in Ks-band images from the NAOS CONICA adaptive optics (AO) system on the ESO Very Large Telescope (VLT). The images were obtained as part of a near-infrared search for highly-obscured supernovae in the nuclear regions of luminous and ultraluminous infrared galaxies. SN 2004ip is located within a circumnuclear starburst at 1.4 arcsec (or 500 pc) projected distance from the K-band nucleus of the luminous infrared galaxy IRAS 18293-3413. The supernova luminosity and light curve are consistent with a core-collapse event suffering from a host galaxy extinction of up to about 40 magnitudes in V-band which is as expected for a circumnuclear starburst environment. This is the first supernova to be discovered making use of AO correction and demonstrates the potential of the current 8-meter class telescopes equipped with AO in discovering supernovae from the innermost nuclear regions of luminous and ultraluminous infrared galaxies.

description: In recent years, organic electronics (OΕ) is one of the fastest growing disciplines in material science. In particular, the term OΕ refers to the study of organic conductive polymers and conductive small molecules as well as their applications in modern electronic devices. The purpose of this thesis was the simulation of OTFTs and the simulation of organic electrochemical transistors (OECTs) with the device simulation framework “ATLAS”. Simulation is an alternative way of experimenting that provides the researcher with more accurate information, much faster and less expensive. First of all, we investigated the low-voltage bottom-gate and top-gate organic transistors and we tried to determine their optimal transistor performance by changing the critical region sizes of the device, channel length (L), active layer thickness (tact) and also the gate oxide thickness (tox). Moreover, we compared the experimental results of a sprayed organic field effect transistor with these simulation results to extract a realistic theoretical model. In the end, we mentioned the reasons that we did not manage to complete the simulation of the electrochemical transistor.

description: In this paper we experimentally test the performance of the recently proposed domain-wall encoding of discrete variables from [Chancellor Quantum Sci. Technol. 4 045004] on Ising model flux qubit quantum annealers. We compare this encoding with the traditional one-hot methods and find that they outperform the one-hot encoding for three different problems at different sizes both of the problem and of the variables. From these results we conclude that the domain-wall encoding yields superior performance against a variety of metrics furthermore, we do not find a single metric by which one hot performs better. We even find that a 2000Q quantum annealer with a drastically less connected hardware graph but using the domain-wall encoding can outperform the next generation Advantage processor if that processor uses one-hot encoding.

description: A recent study suggests that the quasar HE 0450-2958 is hosted by a galaxy substantially fainter than that inferred from the correlation between black hole mass and bulge luminosity. As this result has significant bearings on galaxy and black hole evolution, we revisit the issue by performing an independent analysis of the data, using a two-dimensional image fitting technique. We indeed find no evidence of a host galaxy either, but, due to the brightness of the quasar and uncertainties in the point-spread function, the limits are fairly weak. To derive an upper limit on the host galaxy luminosity, we perform simulations to deblend the quasar from the host under conditions similar to those actually observed. We find that the host galaxy has an absolute magnitude upper limit of -20 < M_V < -21, in good agreement with the previous determination. Since this limit is consistent with the value predicted from the current best estimate of the black hole mass, there is no compelling evidence that the quasar HE 0450-2958 has an abnormally underluminous host galaxy. We also show that, contrary to previous claims, the companion galaxy to HE 0450-2958 should not be be regarded as an ultraluminous infrared galaxy.

Towards a more just refuge regime: quotas, markets and a fair share

description: The international refugee regime is beset by two problems: Responsibility for refuge falls disproportionately on a few states and many owed refuge do not get it. In this work, I explore remedies to these problems. One is a quota distribution wherein states are distributed responsibilities via allotment. Another is a marketized quota system wherein states are free to buy and sell their allotments with others. I explore these in three parts. In Part 1, I develop the prime principles upon which a just regime is built and with which alternatives can be adjudicated. The first and most important principle – ‘Justice for Refugees’ – stipulates that a just regime provides refuge for all who have a basic interest in it. The second principle – ‘Justice for States’ – stipulates that a just distribution of refuge responsibilities among states is one that is capacity considerate. In Part 2, I take up several vexing questions regarding the distribution of refuge responsibilities among states in a collective effort. First, what is a state’s ‘fair share’? The answer requires the determination of some logic – some metric – with which a distribution is determined. I argue that one popular method in the political theory literature – a GDP-based distribution – is normatively unsatisfactory. In its place, I posit several alternative metrics that are more attuned with the principles of justice but absent in the political theory literature: GDP adjusted for Purchasing Power Parity and the Human Development Index. I offer an exploration of both these. Second, are states required to ‘take up the slack’ left by defaulting peers? Here, I argue that duties of help remain intact in cases of partial compliance among states in the refuge regime, but that political concerns may require that such duties be applied with caution. I submit that a market instrument offers one practical solution to this problem, as well as other advantages. In Part 3, I take aim at marketization and grapple with its many pitfalls: That marketization is commodifying, that it is corrupting, and that it offers little advantage in providing quality protection for refugees. In addition to these, I apply a framework of moral markets developed by Debra Satz. I argue that a refuge market may satisfy Justice Among States, but that it is violative of the refugees’ welfare interest in remaining free of degrading and discriminatory treatment.

description: In this master thesis we propose a novel prediction method for predicting the direction of foreign exchange currency pairs quotation, based on deep neural networks, support vector machines and retrieval techniques. Thus ours is a classification problem rather than a regression one. The proposed method uses the retrieval algorithm outcome as input for the deep neural network and the support vector machine. Then the deep neural network and the support vector machine produce an outcome that is used as a Traders investment advisor. In our analysis we show/prove that the models we created, a deep neural network a voting decision algorithm and a support vector machine can outperform the average Trader.

description: Η εργασία πραγματεύεται την εικόνα, την ζωή και την πορεία των μεταναστών ειδικά αυτών που ζουν πλέον νόμιμα ή μη στη Ιταλία. Μέσα από την περιγραφή των ιστοριών των δυο βιβλίων και των κεντρικών τους ηρώων, οι δυο συγγραφείς προβάλλουν για τους μετανάστες μια εικόνα, η οποία επιχειρεί να ανατρέψει σε μεγάλο βαθμό τις προκαταλήψεις και τον τρόπο σκέψης μεγάλου τμήματος της κοινής γνώμης των χωρών υποδοχής σχετικά με τους συγκεκριμένους ανθρώπους. Οι μετανάστες παρουσιάζονται με τρόπο που αναδεικνύει την ευαισθησία τους, καθώς είναι άτομα που ζουν μες στην ανασφάλεια και τον φόβο του αγνώστου, ενώ παράλληλα προσπαθούν να βρούν το κουράγιο και τη δύναμη να οργανώσουν την ζωή τους κατά τον καλύτερο δυνατόν τρόπο. Στην περίπτωση του βιβλίου της LailaWadia, ο ρόλος των γυναικείων χαρακτήρων φαίνεται να είναι εντονότερος σε σύγκριση με ό, τι συμβαίνει στην περίπτωση της ιστορίας του Affinatti. Βέβαια και εδώ δεν παύουν να υφίστανται οι αναφορές σε γυναικείους χαρακτήρες, όπως οι μητέρες των μικρών παιδιών - μεταναστών που είναι οι μαθητές του συγγραφέα. Στο βιβλίο του Affinattiτο κέντρο βάρους βρίσκεται στις ιστορίες των διαφόρων νεαρών μεταναστών και στο πως αυτές λειτουργούν ως εργαλείο και τρόπος, με τα οποία ο ίδιος ο συγγραφέας, θα φτάσει στην αυτογνωσία και στην προσωπική του ψυχογράφηση ως προς την αναζήτηση της μορφής του δικού του πατέρα.
description: The work deals with the image, life and the course of immigrants, especially those who are legally or illegally living in Italy. Through the description of the stories of the two books and their central heroes, the two writers point out to migrants an image that attempts to overthrow the prejudices and the way in which a large part of the host public's opinion about their specific people. Immigrants are presented in a way that highlights their sensitivity, as they are people living in the insecurity and fear of the unknown, while trying to find the courage and power to organize their life in the best possible way. In the case of LailaWadia's book, the role of female characters seems to be more intense than what happens in the case of Affinatti's story. Of course, references to female characters such as the mothers of small children - immigrants who are the students of the writer do not cease to exist. In his book Affinattito, the center of gravity is found in the stories of the various young immigrants and how they act as a tool and way in which the author himself will arrive at his self-knowledge and his personal psychology as to the search for the form of his own father.

description: Rather than using an adaptive optics (AO) system to correct a telescope s entire pupil, it can instead be used to more finely correct a smaller sub-aperture. Indeed, existing AO systems can be used to correct a sub-aperture 1/3 to 1/2 the size of a 5-10 m telescope to extreme adaptive optics (ExAO) levels. We discuss the potential performance of a clear off-axis well-corrected sub-aperture (WCS), and describe our initial imaging results with a 1.5 m diameter WCS on the Palomar Observatory s Hale telescope. These include measured Strehl ratios of 0.92-0.94 in the infrared (2.17 microns), and 0.12 in the B band, the latter allowing a binary of separation 0.34 arc sec to be easily resolved in the blue. Such performance levels enable a variety of novel observational modes, such as infrared ExAO, visible-wavelength AO, and high-contrast coronagraphy. One specific application suggested by the high Strehl ratio stability obtained (1%) is the measurement of planetary transits and eclipses. Also described is a simple dark-hole experiment carried out on a binary star, in which a comatic phase term was applied directly to the deformable mirror, in order to shift the diffraction rings to one side of the point spread function.

description: The action of four-dimensional Horndeski gravity coupled to Born-Infeld electromagnetic fields is given via the Kaluza-Klein process. Dyonic black hole solution of the theory is constructed. The metric is devoid of singularity at the origin independent of the parameter selections, this property is different from the one of Einstein-Born-Infeld black holes. Thermodynamics of the black hole is studied, thermodynamic quantities are calculated and the first law is checked to be satisfied. Thermodynamic phase transitions of the black holes are studied in extended phase space.

description: Thyreostats are orally active substances used in medicine and veterinary work to regulate the production of T3 and T4 hormones by the thyroid gland. They can be illicitly administered to livestock for fattening purposes in order to improve body-weight gain due to an important retention water in edible tissues and in the gastroenteric tract. Their fraudulent utilisation is severely prohibited by the European Union, which requires a precise monitoring. In 2007, European Union of Reference Laboratories in the CRL Guidance paper proposed a recommended concentration of 10 ng mL-1 in urine, which has just been suggested to increase to 30 ng mL-1. In order to facilitate the detection of thyreostats in two bovine matrices, urine and thyroid glands, a method was developed without a previous derivatisation step, frequently used for HPLC analysis of Thiouracil. A salting-out assisted liquid–liquid extraction procedure for preparation was carried out to facilitate the movement of the thyreostats to the tert buthyl methyl ether phase. The HPLC-MS/MS analytical procedure of the method was validated according to the guidelines of Commission Decision 2002/657/EC and has permitted to obtain satisfactory performance parameters and, decision limit and detection capability values for all the thyreostats lower than the recommended values hitherto mentioned.

description: A central problem in Binary Hypothesis Testing (BHT) is to determine the optimal tradeoff between the Type I error (referred to as false alarm) and Type II (referred to as miss) error. In this context, the exponential rate of convergence of the optimal miss error probability -- as the sample size tends to infinity -- given some (positive) restrictions on the false alarm probabilities is a fundamental question to address in theory. Considering the more realistic context of a BHT with a finite number of observations, this paper presents a new non-asymptotic result for the scenario with monotonic (sub-exponential decreasing) restriction on the Type I error probability, which extends the result presented by Strassen in 2009. Building on the use of concentration inequalities, we offer new upper and lower bounds to the optimal Type II error probability for the case of finite observations. Finally, the derived bounds are evaluated and interpreted numerically (as a function of the number samples) for some vanishing Type I error restrictions.
Progesterone Receptor Membrane Component 1 (PGRMC1) in cell division: its role in bovine granulosa cells mitosis

description: The present studies were aimed to assess Progesterone Receptor Membrane Component-1 (PGRMC1) role in regulating bovine granulosa cells (bGC) mitosis. First, we performed immunofluorescence studies on in vitro cultured bGC collected from antral follicles, which showed that PGRMC1 localizes to the spindle apparatus in mitotic cells. Then, to evaluate PGRMC1 effect on cell proliferation we silenced its expression with RNA interference technique (RNAi). Quantitative RT-PCR and immunoblotting confirmed down-regulation of PGRMC1 expression, when compared to CTRL-RNAi treated bGC (p<0.05). After 72h of culture, PGRMC1 silencing determined a lower growth rate (p<0.05) and a higher percentage of cells arrested at G2/M phase as assessed by flowcytometry (p<0.05). Accordingly, live imaging studies revealed more aberrant mitosis and a delayed M-phase in PGRMC1-RNAi treated cells compared to CTRL-RNAi group (p<0.05). These data confirmed that PGRMC1 is directly involved in bGC mitosis and ongoing preliminary studies are aimed to elucidate its putative mechanisms of action. Since PGRMC1 is a membrane protein, we hypothesize its possible involvement in vesicular trafficking and endocytosis, which is in turn an important process to assure proper cell division. To assess this hypothesis, we have preliminarily conducted immunofluorescence and in situ proximity ligation assay experiments that showed PGRMC1 co-localization and direct interaction with clathrin. This is important since clathrin is an essential protein for both endosomes formation, and cell division acting directly on the spindle apparatus. Thus our studies set the stage for analysis aimed to further characterize PGRMC1’s mechanism of action in mitotic cell.
