description: Giant strides in ultrashort laser pulse technology have enabled real-time observation of dynamical processes in complex molecular systems. Specifically, the discovery of oscillatory transients in the two-dimensional electronic spectra of photosynthetic systems stimulated a number of theoretical investigations exploring possible physical mechanisms of the remarkable quantum efficiency of light harvesting processes. However, the theories employed have reached a high degree of sophistication and have become complex, making it difficult to gain insights into microscopic processes and biologically significant questions. In this work, we revisit the elementary aspects of environment-induced fluctuations in the involved electronic energies and present a simple way to understand energy flow with the intuitive picture of relaxation in a funnel-type free-energy landscape. The presented free-energy description of energy transfer reveals that typical photosynthetic systems operate in an almost barrierless regime. The approach also provides insights into the distinction between coherent and incoherent energy transfer and criteria by which the necessity of the vibrational assistance is considered.

description: Metacognitive awareness, highly based on the skills of “knowledge of cognition” and “regulation of cognition”, is a complicated higher-rank cog¬nitive skill that enables the student to plan, monitor and evaluate his/her personal cognitive performance, through the implementation of personal 
strategies for the assimilation of knowledge. The present study aims to adapt G. Schraw’s “Metacognitive Awareness Strategy” to the teaching of Home Economics and, in particular, to the schoolbook’s unit entitled “Issues on Ecology”. This strategy develops in four steps (promoting gener¬al awareness, improving knowledge of cognition, improving regulation of cognition, promoting general skills in conducive environments), each one fostering cognitive, metacognitive and socio-affective development of the student.

On the role of continuum-driven eruptions in the evolution of very massive stars and Population III stars
Creators: name: Smith, Nathan

Publisher: name: arXiv
Year: 2006
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We suggest that the mass lost during the evolution of very massive stars may be dominated by optically thick, continuum-driven outbursts or explosions, instead of by steady line-driven winds. In order for a massive star to become a WR star, it must shed its H envelope, but new estimates of the effects of clumping in winds indicate that line driving is vastly insufficient. We discuss massive stars above roughly 40-50 Msun, for which the best alternative is mass loss during brief eruptions of luminous blue variables (LBVs). Our clearest example of this phenomenon is the 19th century outburst of eta Car, when the star shed 12-20 Msun or more in less than a decade. Other examples are circumstellar nebulae of LBVs, extragalactic eta Car analogs (``supernova impostors''), and massive shells around SNe and GRBs. We do not yet fully understand what triggers LBV outbursts, but they occur nonetheless, and present a fundamental mystery in stellar astrophysics. Since line opacity from metals becomes too saturated, the extreme mass loss probably arises from a continuum-driven wind or a hydrodynamic explosion, both of which are insensitive to metallicity. As such, eruptive mass loss could have played a pivotal role in the evolution and fate of massive metal-poor stars in the early universe. If they occur in these Population III stars, such eruptions would profoundly affect the chemical yield and types of remnants from early SNe and hypernovae.

Συγκριτικά με τις κυβερνήσεις της Νέας Δημοκρατιάς (Ν.Δ) κατά την περίοδο 1974-1981, η κυβέρνηση του ΠΑ.ΣΟ.Κ απέκτησε χαρακτήρα «ανεξάρτητο» και «πολυδιάστατο», αλλάζοντας τους μέχρι τότε αδιαμφισβήτητους όρους της εξωτερικής πολιτικής όπως π.χ. «η Ελλάδα ανήκει εις την Δύση», «οι σχέσεις μεταξύ της Ελλάδας και των Η.Π.Α είναι ο κύριος άξονας στις διεθνείς σχέσεις ».Αναμφισβήτητα, η εξωτερική πολιτική της χώρας κατά την περίοδο 1981-1988 φέρει τη σφραγίδα του ΠΑ.ΣΟ.Κ και του Ανδρέα Παπανδρέου. Από την αντιμετώπιση της Τουρκίας μέχρι την πολιτική απέναντι στον Τρίτο Κόσμο, η εξωτερική πολιτική της χώρας παρουσιάζει έντονα ιδεολογικά-πολιτικά χαρακτηριστικά, αλλά και ρεαλισμό. Φυσικά μια διπλωματική εργασία δεν μπορεί να παρουσιάσει, πόσο μάλλον να αναλύσει τις εξωτερικές σχέσεις της χώρας στο σύνολό τους. Για να δώσουμε όμως το στίγμα της εξωτερικής πολιτικής του ΠΑ.ΣΟ.Κ κατά την περίοδο 1981-1988, θα παρουσιάσουμε τις σχέσεις της Ελλάδος με την Τουρκία, την ΕΟΚ, τις ΗΠΑ, την ΕΣΣΔ , τις βαλκανικές χώρες, τις χώρες του λεγόμενου Τρίτου Κόσμου και την Κίνα προσπαθώντας να την σκιαγραφήσουμε όσο το δυνατόν καλύτερα .
description: The objective of this paper is to introduce the foreign policy of the PASOK government during the period 1981-1988.Comparing with the ND government during the period 1974-1981,the PASOK government demonstrated a more “independent” and “multilateral ” foreign policy, changing some of the Greece’s foreign policy, as for example the axiom “Greece belongs to the West», or “the relations between Greece and the USA are the main focus in the international relations.” The Greek foreign policy during the period 1981-1988 has been marked by PASOK and the Andreas Papandreou. Beginning with the foreign policy to the Turkey and “ the third world” ,the foreign policy of the country demonstrates strongly ideological and political characteristics but also realism. Of course the paper like this cannot present or analyze the total foreign policy of the country. In order to give a representative sample of PASOK foreign policy during the period 1981-1988,we will focus on Greece’s relations with Turkey,E.C,USA,the Balkan countries ,the 3rd World countries and China, trying to present these relations as well as possible.

description: Through this paper, we call for a distributed, internet-based collaboration to address one of the worst plagues of our present world, malaria. The spirit is a non-proprietary peer-production of information-embedding goods. And we propose to use the grid technology to enable such a world wide "open source" like collaboration. The first step towards this vision has been achieved during the summer on the EGEE grid infrastructure where 46 million ligands were docked for a total amount of 80 CPU years in 6 weeks in the quest for new drugs.

description: As the share of renewable sources is increasing the need for multiple storage units appropriately sized and located is essential to achieve better inertial response. This work focuses on the question of "how to distribute constant number of storage units in the gird under transient events such that the inertial response of the maximum frequency deviation is minimized?". To answer this question, we provide a comprehensive modeling framework for energy storage units placement and size for frequency stability under spatial effects. The distributed storage units are modeled as grid supporting inverters and the total storage capacity in the grid is bounded based on the allowed steady-state frequency deviation after disturbances. The problem of finding the optimal distributions can be considered as combinatorial problem which consists of high dimensional solutions. In this light, we develop two numeric approaches based on Brute-force search and adaptation of the Cross-entropy method for finding the best distribution and examined it on a case study of the future Israeli grid. The results on the case study provide a new insight---the storage units should be placed around the area of the disturbances, including in sites with high inertia in accordance to the network topology.

description: In a traditional family model, the death of the protector has become an insurance risk because it causes or is likely to cause permanent loss of income for the other members threatening their living. Purpose of this study are the survivor pensions intended to compensate precisely this constant loss of income. Specifically addressed in detail the circle of protected persons and the conditions for granting benefits to individual insurers. These conditions concern mainly the completion of certain insurance period, duration of marriage, age and state of health of survivors, and the financial resources available to survivors. Details show the survivor pension award problem in case of free association or civil partnership and the treatment by the Greek legislation and case law, and then examined the question of equal treatment between men and women in social security, particularly in death pensions combined with the principle of equality at Community level and the corresponding case law of the ECJ.

description: We study Shubnikov-de Haas oscillations in a p-type WSe$_2$ monolayer under very high magnetic field. The oscillation pattern is complex due to a large spin and valley splitting, in the non-fully-resolved Landau level regime. Our experimental data can be reproduced with a model in which the main parameter is the ratio between the Zeeman energy and the cyclotron energy. The model takes into account the Landau levels from both valleys with the same Gaussian broadening, which allows to predict the relative amplitude of the resistance oscillation originating from each valley. The Zeeman energy is found to be several times larger than the cyclotron energy. It translates into a large and increasing effective Landé factor as the hole density decreases, in the continuity of the values reported in the literature at lower carrier density.

We also show how the generated optomechanical entanglement can be quantified and we suggest an experimental readout-scheme to fully characterize the entangled state. Surprisingly, such optomechanical entanglement is shown to persist for environment temperatures above 20K using state-of-the-art experimental parameters.

description: The starting point of the paper is that in the Greek and in the European context intercultural competence will be one of the key future competences in initial teacher education. The paper discusses the main pillars, on which the intercultural dimension in teacher education should be based: know¬ledge, didactic know-how and attitudes, beliefs as well as teacher behaviour. Positive attitudes toward cultural diversity in schools can be developed in prospective teachers through intercultural training, which refers to a learning procedure, in which student teachers are actively involved and are asked to test the resistance of their attitudes through a variety of teaching methods (role play, case study, brain-storming, analysis of critical incidents, etc.). Intercultural training can eventually lead to the development of intercultur¬al competence in teachers, so that they are enabled to overcome feelings of insufficiency, insecurity and stress and create a positive learning environ¬ment for all children in their culturally diverse classrooms. Finally, the paper presents the European Modular Programme “EMIL” for Intercultural Learning in Teacher Training and Continuing Professional Development, which resulted from a Comenius- project but also points out the restrictions of programmes aiming to develop the intercultural competence in teacher education.

description: Contributing to the need of new graphene nanoribbon (GNR) structures that can be synthesized with atomic precision, we have designed a reactant that renders chiral (3,1) - GNRs after a multi-step reaction including Ullmann coupling and cyclodehydrogenation. The nanoribbon synthesis has been successfully proved on different coinage metals, and the formation process, together with the fingerprints associated to each reaction step, has been studied combining scanning tunnelling microscopy, core-level spectroscopy and density functional calculations. In addition to the GNR chiral edge structure, the substantial GNR lengths achieved and the low processing temperature required to complete the reaction grant this reactant extremely interesting properties for potential applications.

description: We present in this paper an original approach to compute the electrophoretic mobility of rigid nucleo-protein complexes like nucleosomes. This model allows to address theoretically the influence of complex position along DNA, as well as wrapped length of DNA on the electrophoretic mobility of the complex. The predictions of the model are in qualitative agreement with experimental results on mononucleosomes assembled on short DNA fragments (<400bp). Influence of additional experimental parameters like gel concentration, ionic strength, effective charges is also discussed in the framework of the model, and is found to be qualitatively consistent with experiments when available. Based on the present model, we propose a simple semi-empirical formula describing positioning of nucleosomes as seen through electrophoresis.

description: The aim of the present study was the study and investigation of the perceptions of physical education teachers and physiotherapists about the curriculum in schools for students with special needs. The sample consisted of 15 physical education teachers and 15 physiotherapists working in schools for students with special needs. Participants’ perceptions were recorded via a structured interview. Physical education teachers’ responses demonstrated that the curriculum is imperfect and requires radical transformation, doesn’t provides adequate opportunities for its implementation, whereas better training is needed for the educators. The physiotherapists provided similar responses identifying problems in the implementation of the curriculum associated with the medical history and personalized treatment of the students. Both agree that there is sufficient cooperation between the two disciplines, but there is still room for improvement if the appropriate amendments to the curriculum are made. The findings of the study highlight the strengths and weaknesses of the curriculum and provide suggestions to improve it.

description: Exploring the mechanism of interfacial thermal transport and reducing the interfacial thermal resistance is of great importance for thermal management and modulation. Herein, the interfacial thermal resistance between overlapped graphene nanoribbons is largely reduced by adding bonded carbon chains by performing molecular dynamics simulations. And the analytical model (cross-interface model, CIM) is utilized to analyze and explain the two-dimensional thermal transport mechanism at cross-interface. An order of magnitude reduction in interfacial thermal resistance is found as the graphene nanoribbons are bonded by just one carbon chain. Interestingly, the decreasing rate of interfacial thermal resistance slows down gradually with the increasing of the number of carbon chains, which can be explained by the proposed theoretical relationship based on CIM. Moreover, by the comparison of CIM and traditional simplified model, the accuracy of CIM is verified and demonstrated in overlapped graphene nanoribbons. This work provides a new way to improve the interfacial thermal transport and reveal the essential mechanism for low-dimensional materials applied in thermal management.

description: Self-handicapping has been defined in a variety of ways by researchers, but most agree that it involves creating impediments to successful perform¬ance on tasks that the individual considers important. The present work examines the relationship between self-handicapping and self-esteem, the factors that influence the development and acquisition of handicapping behaviors at school and it evaluates the effect that academic self-handicap¬ping has on students’ school achievement. Also, it proposes governing lines for educational confrontation of self-handicapping, aiming at the complete academic and social incorporation of self-handicappers. Because handicap¬ping is part of a cycle of reduced academic effort and lower achievement at school, it may represent early stages of disengagement and withdrawal from school. If researchers and educators can better identify the factors that reduce or promote handicapping, strategies for breaking this cycle of aca¬demic withdrawal can be developed.

description: The field of zero- to ultralow-field (ZULF) nuclear magnetic resonance (NMR) is currently experiencing a rapid growth, owing to the progress in optical magnetometry, and also attractive features of ZULF NMR, such as low hardware cost and excellent spectral resolution achieved under ZULF conditions. In this work, an approach is proposed and demonstrated for simultaneous acquisition of ZULF-NMR spectra of individual 13C-containing isotopomers of chemical compounds in a complex mixture. The method makes use of fast field cycling, so that the spin evolution takes place at ZULF conditions, whereas signal detection is performed in a high-field NMR spectrometer. This method has excellent sensitivity, also allowing easy assignment of ZULF-NMR spectra to specific analytes in the mixture. We demonstrate that the spectral information is the same as that given by ZULF-NMR, which makes the method suitable for creating a library of ZULF-NMR spectra of various compounds and their isotopomers. The results of the field-cycling experiments can be presented in a convenient way as 2D-NMR spectra with the direct detection giving the high-field 13C-NMR spectrum (carrying the chemical-shift information) and the indirect dimension giving the ZULF-NMR spectrum (containing information about proton-carbon J-couplings). Hence, the method can be seen as a variant of heteronuclear J-resolved spectroscopy, one of the first 2D-NMR techniques.

description: The present study was conducted among 159 in-service kindergarten teachers who were attending a degree - qualifying training program at the Department of Early Childhood Education of the University of Athens. The study aimed to explore their conceptual frameworks on the environmental issue of the “greenhouse effect”. The data collecting technique that was used was a free word association task. Among the findings of the study are the following: (a) the “greenhouse effect” is structured as a construct along two basic axes: “global warming” and “climatic extreme events and disas¬ters”, (b) there is a general fusion of ideas concerning different environmen¬tal problems, (c) the well-rooted confusion between the “ozone hole” and “greenhouse effect”, already emerged in previous research, also arises in this study. Conclusions and implications for kindergarten teacher education are further discussed.

description: The standard model of cosmology, the $Λ$CDM model, describes the evolution of the Universe since the Big Bang with just a few parameters, six in its basic form. Despite being the simplest model, direct late-time measurements of the Hubble constant compared with the early-universe measurements result in the so-called $H_0$ tension. It is claimed that a late time resolution is predestined to fail when different cosmological probes are combined. In this work, we shake the ground of this belief with a very simple model. We show how, in the context of cubic vector Galileon models, the Hubble tension can naturally be relieved using a combination of CMB, BAO and SNe observations without using any prior on $H_0$ . The tension can be reduced even further by including the local measurement of the Hubble constant.

description: The Low Energy Neutron Source (LENS) is an accelerator-based pulsed cold neutron facility under construction at the Indiana University Cyclotron Facility (IUCF). The idea behind LENS is to produce pulsed cold neutron beams starting with ~MeV neutrons from (p,n) reactions in Be which are moderated to meV energies and extracted from a small solid angle for use in neutron instruments which can operate efficiently with relatively broad (~1 msec) neutron pulse widths. Although the combination of the features and operating parameters of this source is unique at present, the neutronic design possesses several features similar to those envisioned for future neutron facilities such as long-pulsed spallation sources (LPSS) and very cold neutron (VCN) sources. We describe the underlying ideas and design details of the target/moderator/reflector system (TMR) and compare measurements of its brightness, energy spectrum, and emission time distribution under different moderator configurations with MCNP simulations. Brightness measurements using an ambient temperature water moderator agree with MCNP simulations within the 20% accuracy of the measurement. The measured neutron emission time distribution from a solid methane moderator is in agreement with simulation and the cold neutron flux is sufficient for neutron scattering studies of materials. We describe some possible modifications to the existing design which would increase the cold neutron brightness with negligible effect on the emission time distribution.

description: Searches for new physics push experiments to look for increasingly rare interactions. As a result, detectors require increasing sensitivity and specificity, and materials must be screened for naturally occurring, background-producing radioactivity. Furthermore the detectors used for screening must approach the sensitivities of the physics-search detectors themselves, thus motivating iterative development of detectors capable of both physics searches and background screening. We report on the design, installation, and performance of a novel, low-background, fourteen-element high-purity germanium detector named the CAGe (CUP Array of Germanium), installed at the Yangyang underground laboratory in Korea.

description: We investigate the thermally-induced cyclization of 1,2 - bis(2 - phenylethynyl)benzene on Au(111) using scanning tunneling microscopy and computer simulations. Cyclization of sterically hindered enediynes is known to proceed via two competing mechanisms in solution: a classic C1 - C6 or a C1 - C5 cyclization pathway. On Au(111) we find that the C1 - C5 cyclization is suppressed and that the C1 - C6 cyclization yields a highly strained bicyclic olefin whose surface chemistry was hitherto unknown. The C1 - C6 product self-assembles into discrete non-covalently bound dimers on the surface. The reaction mechanism and driving forces behind non-covalent association are discussed in light of density functional theory calculations.

description: We investigate the evolution of scalar metric perturbations across a sudden cosmological transition, allowing for an inhomogeneous surface stress at the transition leading to a discontinuity in the local expansion rate, such as might be expected in a big crunch/big bang event. We assume that the transition occurs when some function of local matter variables reaches a critical value, and that the surface stress is also a function of local matter variables. In particular we consider the case of a single scalar field and show that a necessary condition for the surface stress tensor to be perturbed at the transition is the presence of a non-zero intrinsic entropy perturbation of the scalar field. We present the matching conditions in terms of gauge-invariant variables assuming a sudden transition to a fluid-dominated universe with barotropic equation of state. For adiabatic perturbations the comoving curvature perturbation is continuous at the transition, while the Newtonian potential may be discontinuous if there is a discontinuity in the background Hubble expansion.

description: Fe$_{1+x}$Te is a two dimensional van der Waals antiferromagnet that becomes superconducting on anion substitution on the Te site. The parent phase of Fe$_{1+x}$Te is sensitive to the amount of interstitial iron situated between the iron-tellurium layers displaying collinear magnetic order coexisting with low temperature metallic resistivity for small concentrations of interstitial iron $x$ and helical magnetic order for large values of $x$. While this phase diagram has been established through scattering [see for example E. E. Rodriguez $\textit{et al.}$ Phys. Rev. B ${\bf{84}}$, 064403 (2011) and S. Rössler $\textit{et al.}$ Phys. Rev. B ${\bf{84}}$, 174506 (2011)], recent scanning tunnelling microscopy measurements [C. Trainer $\textit{et al.}$ Sci. Adv. ${\bf{5}}$, eaav3478 (2019)] have observed a different magnetic structure for small interstitial iron concentrations $x$ with a significant canting of the magnetic moments along the crystallographic $c$ axis of $θ$=28 $\pm$ 3$^{\circ}$. In this paper, we revisit the magnetic structure of Fe$_{1.09}$Te using spherical neutron polarimetry and scanning tunnelling microscopy to search for this canting in the bulk phase and compare surface and bulk magnetism. The results show that the bulk magnetic structure of Fe$_{1.09}$Te is consistent with collinear in-plane order ($θ=0$ with an error of $\sim$ 5$^{\circ}$). Comparison with scanning tunnelling microscopy on a series of Fe$_{1+x}$Te samples reveals that the surface exhibits a magnetic surface reconstruction with a canting angle of the spins of $θ=29.8^{\circ}$. We suggest that this is a consequence of structural relaxation of the surface layer resulting in an out-of-plane magnetocrystalline anisotropy. The magnetism in Fe$_{1+x}$Te displays different properties at the surface when the symmetry constraints of the bulk are removed.

description: We consider decay of metastable states of forced vibrations of a quantum oscillator close to bifurcation points, where dissipation becomes effectively strong. We show that decay occurs via quantum activation over an effective barrier. The decay probability $W$ scales with the distance $η$ to the bifurcation point as $|\ln W|\propto η^ξ$. The exponent $ξ$ is found for a resonantly driven oscillator and an oscillator modulated at nearly twice its eigenfrequency.

description: Main subject of the above thesis is “Things of common use and the protection of the right of common use” . This thesis constitutes a concise study of legal nature of things of common use and protection of right of common use. In the first part, we describe things of common use as they are provided in the Civil Code, with reports in the case law and theory, how a thing can become thing of common use, the way of pause of this attribute, the ownership and the particular rights that can be acquired in these things. In the second part, we analyze the protection of things of common use and the protection of our right of common use with reports in the standpoint of science and case law. We also analyze all possible legal bases of protection of this right. In the end of second part we comment court decisions from the recent case law in order to be clear to the reader the aspect of case law and theory in the subject of protection of things of common use.
