description: In this paper we introduce a novel method to simulate lateral diffusion of inclusions in a fluctuating membrane. The regarded systems are governed by two dynamic processes: the height fluctuations of the membrane and the diffusion of the inclusion along the membrane. While membrane fluctuations can be expressed in terms of a dynamic equation which follows from the Helfrich Hamiltonian, the dynamics of the diffusing particle is described by a Langevin or Smoluchowski equation. In the latter equations, the curvature of the surface needs to be accounted for, which makes particle diffusion a function of membrane fluctuations. In our scheme these coupled dynamic equations, the membrane equation and the Langevin equation for the particle, are numerically integrated to simulate diffusion in a membrane. The simulations are used to study the ratio of the diffusion coefficient projected on a flat plane and the intramembrane diffusion coefficient for the case of free diffusion. We compare our results with recent analytical results that employ a preaveraging approximation and analyze the validity of this approximation. A detailed simulation study of the relevant correlation functions reveals a surprisingly large range where the approximation is applicable.

Infrared finite coupling in Sudakov resummation: the precise set-up

description: I show that Sudakov resummation takes a transparent form if one deals with the second logarithmic derivative of the short distance coefficient functions for deep inelastic scattering and the Drell-Yan process. A uniquely defined Sudakov exponent emerges, and the constant terms not included in the exponent are conjectured to be given by the second logarithmic derivative of the massless quark form factor. The precise framework for the implementation of the dispersive approach to power corrections is set-up, yielding results in agreement with infrared renormalon expectations, but which are not tied to the single (dressed) gluon exchange approximation. Indications for a Banks-Zaks type of perturbative fixed point in the Sudakov effective coupling at low N_f are pointed out. Existence of a fixed point in the Sudakov coupling is argued to imply its universality.

description: Wearable Cognitive Assistants (WCA) are anticipated to become a widely-used application class, in conjunction with emerging network infrastructures like 5G that incorporate edge computing capabilities. While prototypical studies of such applications exist today, the relationship between infrastructure service provisioning and its implication for WCA usability is largely unexplored despite the relevance that these applications have for future networks. This paper presents an experimental study assessing how WCA users react to varying end-to-end delays induced by the application pipeline or infrastructure. Participants interacted directly with an instrumented task-guidance WCA as delays were introduced into the system in a controllable fashion. System and task state were tracked in real time, and biometric data from wearable sensors on the participants were recorded. Our results show that periods of extended system delay cause users to correspondingly (and substantially) slow down in their guided task execution, an effect that persists for a time after the system returns to a more responsive state. Furthermore, the slow-down in task execution is correlated with a personality trait, neuroticism, associated with intolerance for time delays. We show that our results implicate impaired cognitive planning, as contrasted with resource depletion or emotional arousal, as the reason for slowed user task executions under system delay. The findings have several implications for the design and operation of WCA applications as well as computational and communication infrastructure, and additionally for the development of performance analysis tools for WCA.

And we discuss some of their applications to chiral perturbation theory and general relativity.

description: Bulantı ve kusma; acil servise başvuru sebepleri arasında ilk sırada gelen sebepler arasındadır. Bu sebepledir ki; Ondansetron Amerika’da acil serviselerde en sık kullanılan ilaçtır (1). Kusmanın mekanizması tam olarak anlaşılmış olmasa da, kusma merkezinin medulladaki lataral retiküler formasyonda olduğu düşünülüyor (2). Kusma eylemi; kemoreseptör tetikleme alanı (chemoreceptor trigger zone – CTZ), vagal afferent sinirler, serebral kortex ve/veya vestibüler cisimden gelen uyarılar sonrasında, medulladaki nörotransmitterlerin aktivasyonu sonrası gelişir (1-3). Acil servislerde en sık kullanılan antiemetikler; ondansetron, prometazin, metoklopramid ve proklorperazindir (4). Ondansetronun IV uygulamasından sonra etkisinin başlaması 30 dk. civarındadır (5-6). Hatta 2014 yılında Egerton ve ark.’nın 258 hasta ile yaptı prospektif, randomize çift-kör çalışmada; hastalara ondansetron, metoklopramid ve placebo verilmiş. İlk yarım saat içerisinde hastaların bulantı hissindeki azalma miktarları karşılaştırıldığında 2 ilaç ve placebo arasında anlamlı fark görülmediği kaydedilmiştir (7).

description: The interaction of matter with quantum light leads to phenomena which cannot be explained by semiclassical approaches. Of particular interest are states with broad photon number distributions which allow processes with high-order Fock states. Here, we analyze a Jaynes-Cummings-type model with three electronic levels which is excited by quantum light. As quantum light we consider coherent and squeezed states. In our simulations we include several loss mechanisms, namely, dephasing, cavity, and radiative losses which are relevant in real systems. We demonstrate that losses allow one to control the population of electronic levels and may induce coherent population trapping, as well as lead to a redistribution of the photon statistics among the quantum fields and even to a transfer of the photon statistics from one field to another. Moreover, we introduce and analyze a novel quantity, the quantum polarization, and demonstrate its fundamental difference compared to the classical polarization. Using the quantum polarization and the third level population, we investigate electromagnetically induced transparency in the presence of quantum light and show its special features for the case of squeezed light. Finally, quantum correlations between fields are studied and analyzed in the presence of different types of losses.

description: Τα τελευταία χρόνια η βία, η κακοποίηση και η αυτοκτονία των ανηλίκων είναι φαινόμενα που βρίσκονται σε άνοδο. Οι διαστάσεις της βίας στην Ευρώπη και την Αμερική αυξάνονται με ανησυχητικούς ρυθμούς, ενώ ταυτόχρονα αυξάνεται η επίδραση της βίας στα παιδιά μέσω της διαφήμισης. Οι τραυματισμοί ως αποτέλεσμα της βίας είναι η κύρια αιτία της παιδικής θνησιμότητας, ενώ η έκθεση στις διαφημίσεις και γενικότερα στα μέσα επικοινωνίας θεωρείται ότι αυξάνει τη βίαιη και μη ασφαλή συμπεριφορά τους. Σκοπός της παρούσας έρευνας είναι να μελετήσει τη βία στις τηλεοπτικές και διαδικτυακές διαφημίσεις που απευθύνονται σε παιδιά στην Ελλάδα, καθώς η έρευνα που έχει πραγματοποιηθεί για τη βία στις διαφημίσεις που απευθύνονται σε παιδιά των συγκεκριμένων μέσων είναι περιορισμένη. Η μεθοδολογία που χρησιμοποιήθηκε είναι η ανάλυση περιεχομένου των τηλεοπτικών διαφημίσεων που απευθύνονται σε παιδιά και εκτέθηκαν στο ελληνικό κοινό, καθώς και των διαδικτυακών διαφημίσεων που προήλθαν από ελληνικές ιστοσελίδες που απευθύνονται σε παιδιά. Τα συμπεράσματα καταδεικνύουν ότι οι τηλεοπτικές διαφημίσεις που απευθύνονται σε παιδιά περιέχουν μεγάλο ποσοστό βίας, και ιδιαίτερα αυτές που απευθύνονται σε αγόρια. Αποδεικνύεται επίσης ότι οι διαφημίσεις των ιστοσελίδων που απευθύνονται σε παιδιά έχουν βίαιο χαρακτήρα και περιεχόμενο, ενώ συγκεκριμένα η βία παρουσιάζεται σε μεγαλύτερο ποσοστό στα διαφημιστικά πλαίσια (banners) που περιέχουν εικόνα, σε σύγκριση με αυτά που αποτελούνται αποκλειστικά από λέξεις.
description: Over the last years violence, abuse and juveniles’ suicide are phenomena that are continuously increasing. The magnitude of violence increases alarmingly in Europe as well as in America, while simultaneously, the effects of violence over the children via the advertisements constitute the sphere of influence. As a consequence, injuries emerging from violence constitute the primary cause of infant mortality, while children’s display in advertisements and in mass media in general is considered to increase their violent and non-acceptable behavior. The major objective of the present research is to examine the existing violence in television and web advertising aiming at children in Greece, as the accomplished research in this field is limited. The methodology followed is the content analysis of television advertising aiming at children and shown on greek television, as well as of web advertising derived from greek websites aiming at children. The results demonstrate that television advertising aiming at children contains a huge percentage of violence, especially the one aiming at boys. In addition, the present research lays out that web advertising aiming at children incorporates violent disposition and content, while violence, in particular, exists in its highest percentage in banners that contain images, in comparison with those that are solely comprised of text.

We compute the torsion K-theory charges in these D=4, N=1 orientifold models directly from worldsheet conformal field theory, and compare with the K-theory constraints obtained indirectly using D-brane probes. The K-theory torsion charges derived here provide non-trivial constraints on string model building. We also discuss regions of stability for non-BPS D-branes in these examples.

description: Η κατάθλιψη είναι μια ψυχοπαθολογική διαταραχή του συναισθήματος με κύριο χαρακτηριστικό της την επίμονη διάθεση λύπης και άγχους. Ταυτόχρονα, επιφέρει πολλαπλές αλλοιώσεις στις διανοητικές και κινητικές λειτουργίες του ατόμου, και - όχι σπάνια - το ωθεί σε πράξεις αυτοχειρίας. Σύμφωνα με την ψυχιατρική θεώρηση, στην ασθένεια εμπλέκονται αιτιολογικοί παράγοντες βιολογικοί, ψυχολογικοί και κοινωνικοί, ενώ οι άγιοι Πατέρες τονίζουν το συσκοτισμό του νου από την επενέργεια των αρνητικών λογισμών και των παθών, αλλά και την επήρεια των ακάθαρτων πνευμάτων. Η Ψυχιατρική και η Εκκλησία συνεργάζονται αρμονικά για την πληρέστερη αποκατάσταση της ψυχικής και πνευματικής υγείας του πάσχοντος. Ειδικότερα, η Ποιμαντική της Εκκλησίας συμπληρώνει τις επιστημονικές μεθόδους θεραπείας της νόσου με βάση την διαχρονική της παράδοση, κυρίως όμως φροντίζει να την προλαμβάνει. Η προσέγγισή της εστιάζεται στην διακριτική προσπάθεια να πεισθεί ο άρρωστος για τον τρόπο που μετατρέπεται η κατάθλιψη σε ΄κατά Θεόν΄ λύπη διά της καλής μετάνοιας και της συνεχούς αυτογνωσίας. Οι εσωτερικές αυτές διεργασίες συντελούνται μέσα στην Εκκλησία με τη μετοχή στη μυστηριακή ζωή της, αλλά και με την πνευματική και πρακτική άσκηση του προσώπου, το οποίο συνεργεί με τη Θεία Χάρη για την εκούσια πορεία προς τη βίωση του θελήματος του Θεού και της ΄εν Χριστώ΄ αγάπης.
description: Depression is a psychological disorder of the sense and its main characteristic is the insistent feeling of sorrow and anguish. At the same time it brings about multiple changes to the mental and kinetic functions of the person, and – not rarely – it impels him to commit suicide. According to the psychiatric aspect, many causative factors are involved in the disease, biological, psychological and social, while the holy Fathers emphasize the obscuring of the mind due to the influence of negative thoughts and passions, but also the effect of evil spirits. Psychiatry and Church cooperate harmoniously for a more complete restoration of the mental and spiritual health of the sick person. Especially, the Pastorate complements the scientific methods for the cure of the disease on the basis of its timeless tradition, mainly though they intent to prevent it. The approach is focused on the discreet try to convince the diseased of the way to convert the depression to ‘by God’ sorrow through good repentance and continuous self-knowledge. The internal functions take place within the Church with the participation in its occult life, but also with its spiritual and practical exercise of the person, who acts through the Holy Grace for the voluntary course to live the will of God and love of Christ.

Shadows beneath the wind : Singapore, world city and open region
Creators: name: MacLeod, Scott Alexander
Publisher: name: University of British Columbia
Year: 2009

description: This study examines the production of a new regional space known as the Growth Triangle. The Growth Triangle represents a (re)integration of the economies of Singapore, the Riau Archipelago in Indonesia and Johor State in Malaysia. It is argued that the Growth Triangle should be seen as an ‘open region.’ The open region is affected by a wide range of ‘external’ influences and is open to shifting representations which are important to its unfolding. The study takes on the interpretation of the open region through a consideration of the unstable and amorphous realm of ‘middle space.’ Middle space is manifold. It includes: 1) the middle spaces between the global and the local; 2) the middle spaces between conceptual divisions (e.g., urban/rural and labour/capital); and 3) the middle spaces of circulation (i.e., connections between individuals, firms and places). The triangulation of these three arenas provides a heuristic device for the examination of the changes sweeping the Growth Triangle. The analysis moves from a time when the region’s global niche was based on the movement of goods to more recent developments where-in the movement of information and capital are crucial. The global flows of information and capital are the ‘winds’ of the title. The region, and various ways of conceptualizing it, are the ‘shadows.’ The main findings are that: 1) global change must be seen in terms of local roots and consequences; 2) local differentiation and the representation of difference are increasingly important, even in the frame of globalization; 3) analytic strength may be gained by dulling the edges of interpretive constructs (such as information or labour); 4) there are strong connections between the circulation of goods, people, money and information (spatial interaction) and the generation of new and distinct geographies (areal differentiation); and 5) there are strong linkages between Singapore’s shift towards advanced world city functions (‘intensive globalization’) and the mega-urbanization of the near-by international hinterlands (‘extensive globalization’). To understand each of the three corners of the Growth Triangle one must engage Singapore as a World City and as an Open Region.

description: Heavy Ion Collisions (HIC) represent a unique tool to probe the in-medium nuclear interaction in regions away from saturation and at high nucleon momenta. In this report we present a selection of reaction observables particularly sensitive to the isovector part of the interaction, i.e. to the symmetry term of the nuclear Equation of State (EoS) At low energies the behavior of the symmetry energy around saturation influences dissipation and fragment production mechanisms. Predictions are shown for deep-inelastic and fragmentation collisions induced by neutron rich projectiles. Differential flow measurements will also shed lights on the controversial neutron/proton effective mass splitting in asymmetric matter. The high density symmetry term can be derived from isospin effects on heavy ion reactions at relativistic energies (few AGeV range), that can even allow a ``direct'' study of the covariant structure of the isovector interaction in the hadron medium. Rather sensitive observables are proposed from collective flows and from pion/kaon production. The possibility of the transition to a mixed hadron-quark phase, at high baryon and isospin density, is finally suggested. Some signatures could come from an expected ``neutron trapping'' effect.

Constraining the Metallicities of Damped Ly$α$ Systems Using Extinction Curves

Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: In this paper, we present a new method to constrain the metallicities of high redshift damped Ly$α$ (DLA) absorbers using observed extinction curves. This is the first time such an approach is employed to constrain the metallicities of extragalactic absorbers. To demonstrate our method, we use the spectra of 13 quasars and one GRB with DLA absorbers detected along their sightlines. By using the Kramers-Kronig (KK) relation, which relates the wavelength-integrated extinction to the total volume occupied by dust per hydrogen nucleon, we set some robust lower limits on the metallicity of the DLAs. The resulting lower limits are all consistent with the DLA metallicities from the literature. The GRB extinction curve exhibits a very strong 2175 A extinction bump. We try to constrain the metallicity of the GRB DLA by modeling the GRB extinction curve using dust models with two (graphite and silicates) and three (PAH, hydrogenated amorphous carbon, and silicates) dust components. The two-component model resulted in a metallicity of $Z\sim$$-$0.45 while the three-component model gives $Z\sim$$-$0.50. On the other hand, the lower limit from the KK approach for this DLA is $Z\ge$$-$0.60. Modeling a large sample of extinction curves with 2175 A extinction bump and measured DLA metallicities would allow a thorough comparison between the KK and the model-dependent approach. In cases where the precise measurement of the metallicity of a DLA is not possible (e.g. due to the saturation of important absorption lines), the approach presented in this paper can be used to constrain the metallicity.

description: We experimentally investigate the effect of freezing on the spreading of a water drop. Whenever a water drop impacts a cold surface, whose temperature is lower than 0°C, a thin layer of ice grows during the spreading. This freezing has a notable effect on the impact: at given Reynolds and Weber numbers, we show that lowering the surface temperature reduces the drop maximal extent. Using an analogy between this ice layer and the viscous boundary layer, which also grows during the spreading, we are able to model the effect of freezing as an effective viscosity. The scaling laws designed for viscous drop impact can therefore be applied to such a solidification problem, avoiding the recourse to a full and complex modelling of the thermal dynamics.

description: By means of HFB calculations with independent constraints on axial neutron and proton quadrupole moments Q_n and Q_p, we investigate the large amplitude isoscalar and isovector deformation properties of the neutron-rich isotope 20O. Using the particle-number and angular-momentum projected Generator Coordinate Method, we analyze the collective dynamics in the {Q_n, Q_p} plane. The parameterization SLy4 of the Skyrme interaction is used for all calculations in connection with a density-dependent zero-range pairing interaction. Our results show that already for this moderately neutron-rich nucleus the transition moments are modified when independent neutron and proton collective dynamics are allowed.

description: The aim of the present thesis was the study of the religion’s attitude according to euthanasia. Firstly, the reference it has to do with the meaning and the euthanasia was categorized in different ways. Continuing with euthanasia, we have to do with the philosophical reference and the historical background. In the second chapter we had an extensive reference to religions including Christianity, Judaism, Islam, Hinduism and Buddhism. The presentation was completed with the third chapter, referring the legal status and the thesis of many countries, including Greece and the medical ethics according to euthanasia. Moreover, it was represented the relation between brain death and the transplantations. Finally, it was referred the argumentation, which has to do with the euthanasia in nowadays, a very important and current bioethical issue.

description: In many systems, the electronic energy spectrum is a continuous or singular continuous multifractal set with a distribution of scaling exponents. Here, we show that for a quasiperiodic potential, the multifractal energy spectrum can have a minimal dispersion of the scaling exponents. This is made by tuning the ratio between self-energies in a tigth-binding Hamiltonian defined in a quasiperiodic Fibonacci chain. The tuning is calculated numerically from a trace map, and coincides with the place where the scaling exponents of the map, obtained from cycles with period six and two, are equal. The diffusion of electronic wave packets also reflects the minimal multifractal fractal nature of the spectrum, by reducing intermittency. The present result can help to simplify the task of studying several problems in quasiperiodic systems, since the effects of multiscaling are better isolated.

description: We investigate what it means for a (Hausdorff, second-countable) topological group to be computable. We compare several potential definitions in the literature. We relate these notions with the well-established definitions of effective presentability for discrete and profinite groups, and compare these results with similar results in computable topology. Most of these definitions can be separated by counter-examples. Remarkably, we prove that two such definitions are equivalent for locally compact Polish and abelian Polish groups. More specifically, we prove that in these broad classes of groups, every computable topological group admits a right-c.e.~(upper semi-computable) presentation with a left-invariant metric, and a computable dense sequence of points. In the locally compact case, we also show that if the group is additionally effectively locally compact, then we can produce an effectively proper left-invariant metric.
Intracellular expression of an anti-ras single chain Fv

description: The small GTP binding proteins of the Ras superfamily have been implicated in regulating cell growth and differentiation. Much of these data have been generated by the microinjection of the neutralizing antibody to Ras, Y13.259. In studying the role of Ras in mammalian cells I have chosen to attenuate Ras activity by the intracellular expression of a neutralizing anti-Ras single chain Fv (scFv) derived from Y13.259. This approach has the distinct advantage over microinjection in that it permits the study of the biochemical consequence of abrogating Ras activity. The genes for the rat monoclonal, Y13-259, were subcloned and engineered to produce a uni-valent monomeric protein which was shown to recognize the same epitope on Ras (residues 60-76) as the parent antibody molecule. I have successfully expressed scFv-Y13.259 in the SV-40 large-T transformed mouse fibroblast line, SVT-2. Additionally, expression of scFv-Y13.259 did not decrease the half-life of Ras, and the fact that 80-90% of the Ras could be detected complexed with scFv-Y13.259 indicated that this simple method may be useful in uncovering functions of Ras when a given site is masked by the scFv. Furthermore a myristylated version of scFv Y13.259 that localizes to the plasma membrane caused a pronounced change in morphology when expressed in SVT-2 cells. When expressed in the B cell lymphoma line, WEHI-231, results showed that blocking of the Switch II region of Ras by scFv-Y13.259 blocks proliferation and leads to apoptosis. Given that the parental cells respond in the same manner to withdrawal of serum, my results suggest that continued survival and proliferation of this tumor requires a Ras dependant signal from serum. Cell cycle analysis of these scFv-Y13.259 expressing WEHI-231 cells reveals that an apparent block at the G₁ to S phase boundary of the cell cycle was the reason for their eventual demise.

description: The superfluid properties of a two-state Fermi mixture in an optical lattice are profoundly modified when an imbalance in the population of the two states is present.We present analytical solutions for the free energy, and for the gap and number equations in the saddle-point approximation describing resonant superfluidity in the quasi-two-dimensional gas. Inhomogeneities due to the trapping potentials can be taken into account using the local density approximation. Analyzing the free energy in this approximation, we find that phase separation occurs in the layers. The phase diagram of the superfluid and normal phases is derived and analytical expressions for the phase lines are presented. We complete the investigation by accounting for effects beyond mean-field in the BEC limit where the system is more properly described as a Bose-Fermi mixture of atoms and molecules.

description: In this report, we present a discussion about different frameworks to perform precise higher-order computations for high-energy physics. These approaches implement novel strategies to deal with infrared and ultraviolet singularities in quantum field theories. A special emphasis is devoted to the local cancellation of these singularities, which can enhance the efficiency of computations and lead to discover novel mathematical properties in quantum field theories.

description: For the time being, Earth remains the best and only example of a habitable (and inhabited) world. Therefore, it is important to explore and understand the full range of spectral signatures and variability of Earth in order to inform the design of future instruments and missions, and understand their diagnostic power as well as potential limitations. In this work we use Earth observation data collected by the MODIS instrument aboard the Aqua satellite. The complete data set comprises 15 years of thermal emission observations in the 3.66-14.40 microns range for five different locations on Earth (Amazon Rainforest, Antarctica, Arctic, Indian Ocean and the Sahara Desert). We then determine flux levels and variations as a function of wavelength and surface type (i.e. climate zone and surface thermal properties) and investigate whether periodic signals indicating Earth's tilted rotation axis can be detected. Our findings suggest that (1) viewing geometry plays an important role when thermal emission data is analyzed as Earth's spectrum varies by a factor of three and more depending on the dominant surface type underneath; (2) typically strong absorption bands from carbon dioxide (15 microns) and ozone (9.65 microns) are significantly less pronounced and partially absent in data from the polar regions implying that estimating correct abundance levels for these molecules might be challenging in these cases; (3) the time-resolved thermal emission spectrum encodes information about seasons/planetary obliquity, but the significance depends on the viewing geometry and spectral band considered

description: Extra-large massive multiple-input multiple-output (XL-MIMO) systems is a new concept, where spatial non-stationarities allow activate a high number of user equipments (UEs). This paper focuses on a grant-based random access (RA) approach in the novel XL-MIMO channel scenarios. Modifications in the classical Strongest User Collision Resolution (SUCRe) protocol have been aggregated to explore the visibility regions (VRs) overlapping in XL-MIMO. The proposed grant-based RA protocol takes advantage of this new degree of freedom for improving the number of access attempts and accepted UEs. As a result, the proposed grant-based protocol for XL-MIMO systems is capable of reducing latency in the pilot allocation step.
