description: Σκοπός της διατριβής ήταν η έρευνα των απόψεων εκπαιδευτικών στη δευτεροβάθμια εκπαίδευση αναφορικά με τους λόγους που ωθούν τους μαθητές στην Ελλάδα να παρακολουθούν φροντιστήριο, τους λόγους για τους οποίους η επίσημη πολιτεία δεν έχει καταφέρει να περιορίσει το φαινόμενο παρά τις επανειλημμένες εξαγγελίες της, καθώς και τους τρόπους με τους οποίους θα ήταν ίσως εφικτό το φροντιστήριο να πάψει να θεωρείται απαραίτητο από γονείς και μαθητές. Η έρευνα πραγματοποιήθηκε σε 75 Γενικά Λύκεια της Αθήνας και της Θεσσαλονίκης σε δείγμα 785 εκπαιδευτικών. Διαπιστώθηκε ότι οι εκπαιδευτικοί θεωρούν ως σημαντικότερο λόγο προσφυγής στο φροντιστήριο την αύξηση της πιθανότητας της επιτυχούς εισαγωγής των μαθητών στην τριτοβάθμια εκπαίδευση. Αναγνώρισαν τον καθοριστικό ρόλο του φροντιστηρίου συγκριτικά με το σχολείο ως προς την αποτελεσματικότητα της διδασκαλίας, το επίπεδο της επαρκούς προετοιμασίας για τις εισαγωγικές εξετάσεις, του βαθμού κατάρτισης στο γνωστικό αντικείμενο και το επιπλέον διδακτικό υλικό που παρέχεται. Οι συμμετέχοντες εκπαιδευτικοί εκτίμησαν ότι η κατάσταση ίσως θα μπορούσε να αναστραφεί με μία ουσιαστική μεταρρύθμιση στο σύστημα πρόσβασης στην τριτοβάθμια εκπαίδευση που θα αποσυνδέει το Λύκειο από τις εισαγωγικές εξετάσεις (πανελλήνιες).
description: The purpose of the present study was to examine the views of secondary educators/teachers regarding factors that influence students’ decision in Greece to attend “frontistirio”. In addition, this study attempted to explore why the state has been unable to eliminate this phenomenon despite repeated announcements to the contrary and the ways in which it might be possible the “frontistirio” to stop being considered essential by parents and students. Using a survey, 785 teachers from 75 high schools (“lykeia”) in the two largest cities of Greece (Athens and Thessaloniki) participated in the study. Findings showed that increased chances of entering tertiary education was identified by school teachers as the most important reason for students resorting to “frontistirio”. They also acknowledged the academic superiority of “frontistirio” over typical high schools in terms of instructional effectiveness, level of adequate preparation for the entrance exams, subject matter expertise and additional teaching materials provided. Finally, teachers reported that the situation could possibly be reversed through a substantial reform that would disconnect university entrance exams from high school graduation.

description: With the release of the 2MASS All-Sky Point Source Catalog, stellar fluxes from 2MASS are used to remove the contribution due to Galactic stars from the intensity measured by DIRBE in 40 new regions in the North and South Galactic polar caps. After subtracting the interplanetary and Galactic foregrounds, a consistent residual intensity of 14.69 +/- 4.49 kJy/sr at 2.2 microns is found. Allowing for a constant calibration factor between the DIRBE 3.5 microns and the 2MASS 2.2 microns fluxes, a similar analysis leaves a residual intensity of 15.62 +/- 3.34 kJy/sr at 3.5 microns. The intercepts of the DIRBE minus 2MASS correlation at 1.25 microns show more scatter and are a smaller fraction of the foreground, leading to a still weak limit on the CIRB of 8.88 +/- 6.26 kJy/sr (1 sigma).

description: We report on the calculation of the next-to-leading order QCD corrections to the production of a $t\bar{t}$ pair in association with two heavy-flavour jets. We concentrate on the di-lepton $t\bar{t}$ decay channel at the LHC with $\sqrt{s}=13$ TeV. The computation is based on $pp \to e^+ ν_e\, μ^-\barν_μ\, b\bar{b} \,b\bar{b}$ matrix elements and includes all resonant and non-resonant diagrams, interferences and off-shell effects of the top quark and the $W$ gauge boson. As it is customary for such studies, results are presented in the form of inclusive and differential fiducial cross sections. We extensively investigate the dependence of our results upon variation of renormalisation and factorisation scales and parton distribution functions in the quest for an accurate estimate of the theoretical uncertainties. We additionally study the impact of the contributions induced by the bottom-quark parton density. Results presented here are particularly relevant for measurements of $t\bar{t}H(H\to b\bar{b})$ and the determination of the Higgs coupling to the top quark. In addition, they might be used for precise measurements of the top-quark fiducial cross sections and to investigate top-quark decay modelling at the LHC.

description: Εστιάζοντας στην πλούσια και ανεξάντλητη θεματική της επιστημονικής αναπαράστασης, αποπειράθηκα να μελετήσω τις θέσεις και τα επιχειρήματα των Bas van Fraassen και Anjan Chakravartty ―δύο σημαίνοντες φιλόσοφοι που εκπροσωπούν τα ρεύματα του αντιρεαλισμού και του επιστημονικού ρεαλισμού, αντιστοίχως― σχετικά με τους τρόπους αναπαραστατικής απόκλισης. Το φιλοσοφικό ενδιαφέρον ως προς την ενσωμάτωση χαρακτηριστικών εκτροπής και απομάκρυνσης από την πραγματικότητα εντός της ανθρώπινης δραστηριότητας που εξ ορισμού στοχεύει στο γνωσιακό πλησίασμα του φυσικού κόσμου είναι αδιαμφισβήτητο. Ως εκ τούτου, για τη σύγχρονη φιλοσοφία της επιστήμης, η διερεύνηση αυτής της προβληματικής οφείλει να έχει βαρύνουσα σημασία. Εξάλλου, δεν πρόκειται για μια θεωρητική παραδοξολογία ή ένα φιλοσοφικό οξύμωρο, αλλά για ένα δύσκολο και απαιτητικό ζήτημα, που διαπερνά και επικαθορίζει την καθημερινότητα της επιστημονικής πρακτικής και, κυρίως, έχει εξαιρετικά κρίσιμες προεκτάσεις στο πεδίο της γνωσιοθεωρίας.
description: Focusing on the rich and inexhaustible subject matter of scientific representation, I endeavoured to delve into the views and arguments of Bas van Fraassen and Anjan Chakravartty ―two major philosophers which advocate the currents of antirealism and scientific realism, respectively― with regard to the ways of representational deviation. The philosophical interest pertaining to the inclusion of features of divergence and digression from reality within the human activity which by definition aims at the cognitive approximation of the natural world is unquestionable. Therefore, for the contemporary philosophy of science, the inquiry into this issue should be deemed as one of great importance. Besides, this is not a theoretical paradox or a philosophical oxymoron, but it is a challenging and demanding issue, which penetrates and shapes the routine of scientific practice and, principally, has a crucial impact on the field of epistemology.
Probabilistic Cross-Identification of Astronomical Sources

description: We present a general probabilistic formalism for cross-identifying astronomical point sources in multiple observations. Our Bayesian approach, symmetric in all observations, is the foundation of a unified framework for object matching, where not only spatial information, but physical properties, such as colors, redshift and luminosity, can also be considered in a natural way. We provide a practical recipe to implement an efficient recursive algorithm to evaluate the Bayes factor over a set of catalogs with known circular errors in positions. This new methodology is crucial for studies leveraging the synergy of today's multi-wavelength observations and to enter the time-domain science of the upcoming survey telescopes.

description: The malware and botnet phenomenon is among the most significant threats to cybersecurity today. Consequently, law enforcement agencies, security companies, and researchers are constantly seeking to disrupt these malicious operations through so-called takedown counter-operations. Unfortunately, the success of these takedowns is mixed. Furthermore, very little is understood as to how botnets and malware delivery operations respond to takedown attempts. We present a comprehensive study of three malware delivery operations that were targeted for takedown in 2015-16 using global download metadata provided by a major security company. In summary, we found that: (1) Distributed delivery architectures were commonly used, indicating the need for better security hygiene and coordination by the (ab)used service providers. (2) A minority of malware binaries were responsible for the majority of download activity, suggesting that detecting these "super binaries" would yield the most benefit to the security community. (3) The malware operations exhibited displacing and defiant behaviours following their respective takedown attempts. We argue that these "predictable" behaviours could be factored into future takedown strategies. (4) The malware operations also exhibited previously undocumented behaviours, such as Dridex dropping competing brands of malware, or Dorkbot and Upatre heavily relying on upstream dropper malware. These "unpredictable" behaviours indicate the need for researchers to use better threat-monitoring techniques.

Averaging of the electron effective mass in multicomponent transparent conducting oxides
Creators: name: Medvedeva, J. E.

description: We find that layered materials composed of various oxides of cations with $s^2$ electronic configuration, $XY_2$O$_4$, $X$=In or Sc, $Y$=Ga, Zn, Al, Cd and/or Mg, exhibit isotropic electron effective mass which can be obtained via averaging over those of the corresponding single-cation oxide constituents. This effect is due to a hybrid nature of the conduction band formed from the s-states of {\it all} cations and the oxygen p-states. Moreover, the observed insensitivity of the electron effective mass to the oxygen coordination and to the distortions in the cation-oxygen chains suggests that similar behavior can be expected in technologically important amorphous state. These findings significantly broaden the range of materials as efficient transparent conductor hosts.

description: Motivated by the discovery of the quantum anomalous Hall effect in Cr-doped \ce{(Bi,Sb)2Te3} thin films, we study the generic states for magnetic topological insulators and explore the physical properties for both magnetism and itinerant electrons. First-principles calculations are exploited to investigate the magnetic interactions between magnetic Co atoms adsorbed on the \ce{Bi2Se3} (111) surface. Due to the absence of inversion symmetry on the surface, there are Dzyaloshinskii-Moriya-like twisted spin interactions between the local moments of Co ions. These nonferromagnetic interactions twist the collinear spin configuration of the ferromagnet and generate various magnetic orders beyond a simple ferromagnet. Among them, the spin spiral state generates alternating counterpropagating modes across each period of spin states, and the skyrmion lattice even supports a chiral mode around the core of each skyrmion. The skyrmion lattice opens a gap at the surface Dirac point, resulting in the anomalous Hall effect. These results may inspire further experimental investigation of magnetic topological insulators.

Accretion disc coronae in black hole binaries

Publisher: name: arXiv
Year: 2007
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: Most of the luminosity of accreting black hole is emitted in the X-ray band. This radiation is believed to emerge, through inverse Compton process, from a hot (Te ~ 10^8 -10^9 K) optically thin (Thomson optical depth ~ 1) plasma probably located in the immediate vicinity of the black hole. The mechanisms at work in this so called Compton corona can be unveiled through hard X-ray observations which have revealed a rich phenomenology. Depending on luminosity different spectral states are observed suggesting that the nature and geometry of the corona depends on mass accretion rate. In many instances the spectral behaviour as a function of luminosity shows some degree of hysteresis. The mechanisms triggering the transition between spectral states is very unclear although it could be related to an evaporation/condensation equilibrium in an accretion disc corona system. From the observation of correlation between the X-ray and radio band, it appears that the Compton corona is intimately related to the formation of compact jets and probably constitutes the base of the jet.

description: Using low energy Time-of-Flight Scattering and Recoil Spectroscopy (TOF-SARS) and Mass Spectroscopy of Recoiled Ions (MSRI) we analyze the surface structure of an atomically smooth BaBiO$_3$ film grown by molecular beam epitaxy. We demonstrate high sensitivity of the TOF-SARS and MSRI spectra to slight changes in the orientation of the ion scattering plane with respect to the crystallographic axes. The observed angle dependence allows us to clearly identify the termination layer as BiO$_2$. Our data also indicate that angle-resolved MSRI data can be used for high resolution studies of surface structure of complex oxide thin films.

Evaluation of the Tri Star vibrocompaction probe
Creators: name: Brown, David F.
Publisher: name: University of British Columbia
Year: 2010

description: The Franki Tri Star method for deep compaction of saturated sands has been used on a project on Annacis Island, Vancouver, B.C., Canada. The objective of soil compaction was to stabilize a deep saturated sand deposit, which was susceptible to liquefaction during strong earth quakes. The project involved the compaction of a 750 feet long by 15 feet wide strip of sand deposits down to 10m depth. The sand was overlain by a fill and a clayey silt layer of 2 to 5m thickness. Because of the silt layer and the presence of thin silt and clay seams in the sand, the soil was judged marginal for vibrocompaction. Therefore, extensive tests were performed on site to develop the optimal compaction procedure (vibration time, frequency of compaction and grid spacing). The compaction process was monitored by vibration measurements on the ground surface. In this way, it was possible to determine the time required for densification and to establish the optimal vibration frequency. In order to monitor the Tri Star probe the contractor carried out testing with the help of the site investigation firm, ConeTec, and in collaboration with the University of British Columbia (U.B.C.). U.B.C. monitored the long term effects, primarily with the Piezometer Cone Test (CPTU) and investigated the use of the Flat Plate Dilatometer (DMT) and Seismic Piezometer Cone Test (SCPTU). In addition, the Lateral Stress Piezometer Cone Test (LSCPTU) was used. All testing yielded before and after treatment results, with the CPTU giving progressive time and distance effects. The contractor and consultant also carried out Standard Penetration Tests (SPT), CPTU testing and measured ground settlement before, during and after treatment. The testing has proven that the Tri Star system is an efficient method to compact soil deposits which are susceptible to liquefaction. In particular an increase in penetration resistance of between 200 and 400% was recorded and the probe's zone of influence was found to be of 2m radius. The DMT and CPTU provided similar results and on comparison to the LSCPTU suggested that increases in relative density and lateral stress contributed approximately equally to the soil improvement. The SCPTU provided relatively inconclusive results.
Morphologies of AGN host galaxies using HST/ACS in the CDFS-GOODS field

description: Using HST/ACS images in four bands F435W, F606W, F775W and F850LP, we identify optical counterparts to the X-ray sources in the Chandra Deep Field South in the GOODS South field. A detailed study has been made of these sources to study their morphological types. We use methods like decomposition of galaxy luminosity profiles, color maps and visual inspection of 192 galaxies which are identified as possible optical counterparts of Chandra X-ray sources in the CDFS-GOODS field. We find that most moderate luminosity AGN hosts are bulge dominated in the redshift range (z \approx 0.4-1.3), but not merging/interacting galaxies. This implies probable fueling of the moderate luminosity AGN by mechanisms other than those merger driven.

Evolution of Magnetic Fields in Stars Across the Upper Main Sequence: II. Observed distribution of the magnetic field geometry

description: We re-discuss the evolutionary state of upper main sequence magnetic stars using a sample of Ap and Bp stars with accurate Hipparcos parallaxes and definitely determined longitudinal magnetic fields. We confirm our previous results obtained from the study of Ap and Bp stars with accurate measurements of the mean magnetic field modulus and mean quadratic magnetic fields that magnetic stars of mass M < 3 M_sun are concentrated towards the centre of the main-sequence band. In contrast, stars with masses M > 3 M_sun seem to be concentrated closer to the ZAMS. The study of a few known members of nearby open clusters with accurate Hipparcos parallaxes confirms these conclusions. Stronger magnetic fields tend to be found in hotter, younger and more massive stars, as well as in stars with shorter rotation periods. No evidence is found for any loss of angular momentum during the main-sequence life. The magnetic flux remains constant over the stellar life time on the main sequence. An excess of stars with large obliquities beta is detected in both higher and lower mass stars. The obliquity angle distribution as inferred from the distribution of r-values appears random at the time magnetic stars become observable on the H-R diagram. After quite a short time spent on the main sequence, the obliquity angle beta tends to reach values close to either 90 deg or 0 deg for M < 3 M_sun. The evolution of the obliquity angle beta seems to be somewhat different for low and high mass stars. While we find a strong hint for an increase of beta with the elapsed time on the main sequence for stars with M > 3 M_sun, no similar trend is found for stars with M < 3 M_sun. However, the predominance of high values of beta at advanced ages in these stars is notable.

description: In [C.W. Gear, T.J. Kaper, I.G. Kevrekidis, and A. Zagaris, Projecting to a Slow Manifold: Singularly Perturbed Systems and Legacy Codes, SIAM J. Appl. Dyn. Syst. 4 (2005) 711-732], we developed a class of iterative algorithms within the context of equation-free methods to approximate low-dimensional, attracting, slow manifolds in systems of differential equations with multiple time scales. For user-specified values of a finite number of the observables, the m-th member of the class of algorithms (m = 0, 1, ...) finds iteratively an approximation of the appropriate zero of the (m+1)-st time derivative of the remaining variables and uses this root to approximate the location of the point on the slow manifold corresponding to these values of the observables. This article is the first of two articles in which the accuracy and convergence of the iterative algorithms are analyzed. Here, we work directly with explicit fast--slow systems, in which there is an explicit small parameter, epsilon, measuring the separation of time scales. We show that, for each m = 0, 1, ..., the fixed point of the iterative algorithm approximates the slow manifold up to and including terms of O(epsilon^m). Moreover, for each m, we identify explicitly the conditions under which the m-th iterative algorithm converges to this fixed point. Finally, we show that when the iteration is unstable (or converges slowly) it may be stabilized (or its convergence may be accelerated) by application of the Recursive Projection Method. Alternatively, the Newton-Krylov Generalized Minimal Residual Method may be used. In the subsequent article, we will consider the accuracy and convergence of the iterative algorithms for a broader class of systems-in which there need not be an explicit small parameter-to which the algorithms also apply.

Building Trust and Empathy: Student Voice and Teachers’ Professional Development With Technology
Creators: name: Morris, D.
Publisher: name: The School of Education and Communities, University of East London
Year: 2018

description: This article reflects on the importance of trust between pupils and teachers in student voice initiatives and how cultivating ‘authentic’ trust can lead to a heightened empathy between students and teachers. The research findings presented here stem from doctoral fieldwork carried out in an English secondary school. The study – known as the ‘Teach a Teacher’ project – involved Year 8 pupils (12- to 13-year-olds) providing professional development in information and communication technology (ICT) for their teachers. Data were gathered through observations of teachers and pupils working together, focus groups with pupils, and one-to-one interviews with the teachers involved. This article does not have the scope to explore the school environment or the climate and conditions needed to organise student–teacher partnerships or the role that school leadership plays in supporting these. Rather this article seeks to identify how students as joint authors of ‘emancipatory’ practice were involved in providing their teachers with professional development with their computer skills and therefore actively involved in bringing about change (Fielding 2001, 2011). The findings presented in this article demonstrate that when pupils are entrusted by teachers to take charge of their professional learning, there is a transformation in teacher–pupil relationships. There was wide acceptance of the role reversal this involved, with teachers seeing it as a positive experience in terms of learning from their students. Pupils gained a new perspective and insight into what the job of teaching entails. In this way, the project led to feelings of understanding, empathy and respect from the pupils.
Random-phase-approximation-based correlation energy functionals: Benchmark results for atoms

description: The random phase approximation (RPA) for the correlation energy functional of density functional theory has recently attracted renewed interest. Formulated in terms of the Kohn-Sham (KS) orbitals and eigenvalues, it promises to resolve some of the fundamental limitations of the local density and generalized gradient approximations, as for instance their inability to account for dispersion forces. First results for atoms, however, indicate that the RPA overestimates correlation effects as much as the orbital-dependent functional obtained by a second order perturbation expansion on the basis of the KS Hamiltonian. In this contribution, three simple extensions of the RPA are examined, (a) its augmentation by an LDA for short-range correlation, (b) its combination with the second order exchange term, and (c) its combination with a partial resummation of the perturbation series including the second order exchange. It is found that the ground state and correlation energies as well as the ionization potentials resulting from the extensions (a) and (c) for closed sub-shell atoms are clearly superior to those obtained with the unmodified RPA. Quite some effort is made to ensure highly converged RPA data, so that the results may serve as benchmark data. The numerical techniques developed in this context, in particular for the inherent frequency integration, should also be useful for applications of RPA-type functionals to more complex systems.

description: New surprises continue to be revealed about La$_2$CuO$_4$, the parent compound of the original cuprate superconductor. Here we present neutron scattering evidence that the structural symmetry is lower than commonly assumed. The static distortion results in anisotropic Cu-O bonds within the CuO$_2$ planes; such anisotropy is relevant to pinning charge stripes in hole-doped samples. Associated with the extra structural modulation is a soft phonon mode. If this phonon were to soften completely, the resulting change in CuO$_6$ octahedral tilts would lead to weak ferromagnetism. Hence, we suggest that this mode may be the "chiral" phonon inferred from recent studies of the thermal Hall effect. We also note the absence of interaction between the antiferromagnetic spin waves and low-energy optical phonons, in contrast to what is observed in hole-doped samples.

A Narrative Structure for Teacher Educator Team Analysis and Development
Creators: name: Webb, C.
Publisher: name: The School of Education and Communities, University of East London
Year: 2018

description: United Kingdom (UK) teacher educators in the midst of professional practice changes have been reported to find benefit in being exposed to different theories with a view to resolving conflicting demands and developing new perspectives. This paper provides a synthesis of theories that can help teacher educator teams in universities to make sense of changes in practice together. The theoretical synthesis presented includes models of stages of team development, sense-making, experiential learning and complexity science principles. It is here argued that such a deftly applied synthesis can then facilitate higher education institution (HEI) education department teams to create individual narratives with a view to then sharing them with each other to develop a group narrative. The purpose and benefits of this would immediately be sought in improving team functioning and performance in order to create a more solid foundation from which individuals might even begin to engage in career development along the fellowship trajectory assumed by the UK Higher Education Academy (HEA). A key assumption this paper rests on therefore is that team functioning is a positive asset that is pivotal to individual career development and prerequisite impacts on teaching and learning, and leadership and management of coaching and mentoring with respect to these in a department or team. The contribution this paper makes therefore is a practical approach for analysing and further developing academic teams of teacher educators in a landscape of continual professional change, with a greater theoretical toolkit to draw from to achieve this.

description: The modularity of a network quantifies the extent, relative to a null model network, to which vertices cluster into community groups. We define a null model appropriate for bipartite networks, and use it to define a bipartite modularity. The bipartite modularity is presented in terms of a modularity matrix B; some key properties of the eigenspectrum of B are identified and used to describe an algorithm for identifying modules in bipartite networks. The algorithm is based on the idea that the modules in the two parts of the network are dependent, with each part mutually being used to induce the vertices for the other part into the modules. We apply the algorithm to real-world network data, showing that the algorithm successfully identifies the modular structure of bipartite networks.

description: Η μετακρατική δικαιοσύνη αποτελεί μια πρόταση μεταρρύθμισης του ισχύοντος δικαιοδοτικού συστήματος μέσω της διευρυμένης παρουσίας του ιδιωτικού τομέα στο χώρο της επίλυσης των διαφορών. Ο ανταγωνισμός κράτους και ιδιωτών στην αγορά δικαιοδοτικών υπηρεσιών θα συμβάλλει στην καλύτερη επικοινωνία δικαίου και κοινωνικού περιβάλλοντος, τη μείωση του συναλλακτικού κόστους και την εμβάθυνση της συλλογικής και ατομικής αυτονομίας. Σε αυτή την κατεύθυνση προτείνονται μέτρα υπέρ της προώθησης της Εναλλακτικής Επίλυσης Διαφορών, της οικονομικής ισοτιμίας κρατικών και ιδιωτικών δικαιοδοτικών φορέων, της οργανωτικής αναδιάρθρωσης του δικαστικού μηχανισμού και της αναμόρφωσης της δικονομικής νομοθεσίας, με σκοπό την ενίσχυση της αποτελεσματικότητας της δικαιοσύνης προς όφελος της οικονομίας και της κοινωνίας εν γένει από μια φιλελεύθερη οπτική γωνία.
description: Post-State justice is a proposal for reforming the current judicial system by enhancing private sector's presence in the field of dispute resolution. State and private individuals’ competition in the market of judicial services will provide better interaction between law and the social environment, reduce transaction costs and deepen individual and collective autonomy. To this purpose measures are proposed for promoting Alternative Dispute Resolution, economic equity between public and private judicial institutions, as well as restructuring of the Judiciary and the civil procedure, in order to improve judicial efficiency for the benefit of the economy and society in general from a liberal point of view.

description: В статье на основе анализа массива мемуарной литературы рассматривается кружковая деятельность учащихся Тобольской сельскохозяйственной школы в начале ХХ в. Установлено, что небольшой кружок в школе находился под влиянием социал-демократов и действовал в Тобольске наряду с кружками воспитанников других учебных заведений. Сравнение текстов воспоминаний позволило выявить расхождения в описаниях и оценке событий их участниками, что во многом определяется идеологическими установками, господствовавшими в период написания мемуаров.
description: Based on the analysis of the array of memoir literature, the article examines the club’s activity of students of the Tobolsk agricultural School in the early twentieth century. It is established that a small club at the school was influenced by the Social Democrats and functioned in Tobolsk along with clubs of pupils of other educational institutions. Comparison of the texts of the memoirs revealed discrepancies in the descriptions and assessment of events by their participants, which is largely determined by the ideological attitudes that prevailed during the writing of the memoirs.

A Higgs-Higgs bound state due to New Physics at a TeV

description: We examine the effects of new physics effecting the Higgs sector of the standard model, focusing on the effects on the Higgs self couplings. We demonstrate that a low mass higgs, m_h < 2 m_t, can have a strong effective self coupling due to the effects of a new interaction at a TeV. We investigate the possibility that the first evidence of such an interaction could be a higgs-higgs bound state. To this end, we construct an effective field theory formalism to examine the physics of such a low mass higgs boson. We explore the possibility of a non relativistic bound state of the higgs field (Higgsium) at LHC and construct a non relativistic effective field theory of the higgs sector that is appropriate for such studies (NRHET).

Using Jungian Archetypes in Contemporary Songwriting Education
Creators: name: Blacklaw, A.
Publisher: name: The School of Education and Communities, University of East London
Year: 2018

description: Archetypes are character prototypes, which manifest, often unconsciously, in cultures around the world. They are now being used consciously in creative industries (including screenplay writing and advertising). In this article I explore how they may manifest unconsciously in contemporary popular songwriting, and describe how I have used them creatively and consciously in teaching songwriting to undergraduate students. I intend to illustrate that archetypes serve successfully in teaching songwriting students how to access creative stimulus, as the metaphorical nature of archetypes often enables students to see things differently and create songs accordingly that feel satisfying and authentic to them. This works best as an emotional, rather than an entirely intellectual, exercise.

description: The concept of thermal machines has evolved from the canonical steam engine to the recently proposed nanoscopic quantum systems as working fluids. The latter obey quantum open system dynamics and frequently operate in non-equilibrium conditions. However, the role of this dynamics in the overall performance of quantum heat engines remains an open problem. Here, we analyse and optimize the efficiency and power output of two-stage quantum heat engines fuelled by non-equilibrium steady states. In a charging first stage, the quantum working fluid consisting of a qutrit or two coupled qubits is connected to two reservoirs at different temperatures, which establish a heat current that stores ergotropy in the system; the second stage comprises a coherent driving force that extracts work from the machine in finite a amount of time; finally, the external drive is switched off and the machine enters a new cycle.
