description: It has been recently proposed by Maldacena and Qi that an eternal traversable wormhole in a two dimensional Anti de Sitter space (${\rm AdS}_2$) is the gravity dual of the low temperature limit of two Sachdev-Ye-Kitaev (SYK) models coupled by a relevant interaction (which we will refer to as spin operator). In this paper, we study spectral and eigenstate properties of this coupled SYK model. We have found that level statistics in the tail of the spectrum, and for a sufficiently weak coupling, shows substantial deviations from random matrix theory which suggests that traversable wormholes are not quantum chaotic. By contrast, for sufficiently strong coupling, corresponding to the black hole phase, level statistics are well described by random matrix theory. This transition in level statistics coincides approximately with a previously reported Hawking-Page transition for weak coupling. We have shown explicitly that this thermodynamic transition turns into a sharp crossover as the coupling increases. Likewise, this critical coupling also corresponds with the one at which the overlap between the ground state and the thermofield double state (TFD) is smallest. In the range of sizes we can reach by exact diagonalization, the ground state is well approximated by the TFD state only in the strong coupling limit. This is due to the fact that the ground state is close to the eigenstate of the spin operator corresponding to the lowest eigenvalue which is an exact TFD state at infinite temperature. In this region, the spectral density is separated into blobs centered around the eigenvalues of the spin operator. For weaker couplings, the exponential decay of coefficients in a tensor product basis, typical of the TFD, becomes power law. Finally, we have also found that the total Hamiltonian has an additional discrete symmetry which has not been reported previously.

Subjects: language awareness; foreign language; EFL teachers; beliefs; learning strategies

description: The present study aimed at investigating the role of language awareness from the teachers’ perspective as well as its relationship with other aspects of EFL teacher knowledge. The study was designed and conducted with the aim of providing an account of the issues related to EFL teachers’ language awareness and their beliefs about how students learn a foreign language. Questionnaires were distributed to a total of 150 EFL teachers employed in public primary and secondary schools in Northern Greece. The findings indicated that the participants were conscious to a certain degree of the need for raising language awareness in the EFL classroom and developing students’ language learning strategies.

Nominal forms in extra-syntactic constructions in Ancient Greek: Τhe case of the vocative and exclamative nominative
Creators: name: Kakarikos, Konstantinos
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2011
Subjects: Address Phrase; case; definiteness; exclamative nominative; vocative

description: A typical argument for the independence of morphology is its asymmetric relation with syntax. In ancient Greek this is illustrated by nominal forms in the vocative or the exclamative nominative which, despite their clear morphological representation, express no relation to a syntactic head. Such a remark raises problems regarding the syntactic and morphological status of both forms and their relation to regular cases. In this paper, we re-examine both constructions and claim that their idiosyncratic character is explained by the different type of features involved in their syntactic definition. These are the Address Phrase and the feature of syntactic definiteness.

description: We present a class of models that describe self diffusion on several fcc(001) metal substrates within a common framework. The models are found to apply well for Cu(001), Ag(001), Au(001), Ni(001) and Pd(001).For each of these metals the models can be used to estimate the activation energy of any diffusion process using a few basic parameters which may be obtained from experiments, ab-initio or semi-empirical calculations. To demonstrate the approach, the parameters of the models are optimized to describe self-diffusion on the (001) surface, by comparing the energy barriers to a full set of barriers obtained from semi-empirical potentials via the embedded atom method (EAM). It is found that these models with at most four parameters,provide a good description of the full landscape of hopping energy barriers on FCC(001) surfaces. The main features of the diffusion processes revealed by EAM calculations are quantitatively reproducible by the models.

description: The existence of a dilaton (or moduli) with gravitational-strength coupling to matter imposes stringent constraints on the allowed energy scale of cosmic strings, $η$. In particular, superheavy gauge strings with $η\sim 10^{16} GeV$ are ruled out unless the dilaton mass $m_ϕ \gsim 100 TeV$, while the currently popular value $m_ϕ \sim 1 TeV$ imposes the bound $η\lsim 3 \times 10^{11} GeV$. Similar constraints are obtained for global topological defects. Some non-standard cosmological scenarios which can avoid these constraints are pointed out.

Modelling and Analysis of Energy and Electricity Sectors for Sustainable Development in Bangladesh
Creators: name: Sieed, Jubair
Publisher: name: Zenodo
Year: 2021

description: Access to affordable and clean energy is one of the basic requirements for sustainable growth. Bangladesh, being one of the developing nations, currently faces rapid growth in the energy and electricity sectors. However, this growth might cause energy security issues as natural gas, the main source of primary energy and electricity is depleting quickly and might be totally depleted by the next decade if no new gas-fields are discovered. Local and imported coal could be an alternative to natural gas, which causes environmental pollution by emitting carbon dioxide and other greenhouse gases. Nuclear and renewable energy sources are also considered as future solutions to the energy security problem even though large penetration of such newer technologies often face poor infrastructure related issues in developing regions. In this study, the main focus is to analyze the current energy-economic situation of the country and customize different energy modelling tools to provide policy insights for sustainable development in theenergy and electricity sectors.

Sluicing and asymmetries in the Cypriot-Greek wh-question formation

Year: 2011
Subjects: embu strategy; indambu reanalysis; sluicing remnants; Non-Transfer

description: This paper examines the asymmetry in the occurrence of the embu strategy in Cypriot Greek (CG) wh-questions. I propose that the apparent obligatoriness of embu in inda wh-arguments actually derives from the fact that inda and ’mbu occupy Spec,CP in these interrogatives. This is supported by the syntactic behavior of indambu with respect to sluicing. In light of the asymmetries in sluices, I suggest an adapted version of the sluicing deletion approach. Under this approach, sluicing applies to the C phase head and its domain. Thus, only the elements occupying the specifier of CP are allowed to appear as sluicing remnants.

tac.tic: Tactile design language for indoor-outdoor pedestrian navigation
Creators: name: Chirag Murthy
Publisher: name: Carnegie Mellon University
Year: 2019
Subjects: Design

description: People navigate through indoor and outdoor spaces all the time, and these environments are rich with visual and audio information, and noise. This poses a challenge to someone trying to navigate in a new environment. While GPS services like Google Maps help, they demand visual attention in an already visually stimulating environment. It is not possible to navigate while talking on the phone. They also keep one hand busy. Audio-based turn-by-turn navigation, while useful in certain scenarios, temporarily mutes the outside world for a pedestrian. In addition, these services do not work very well for people with visual and hearing impairments.
tac.tic is a tactile design language for indoor-outdoor pedestrian navigation. It consists of a sleeve with 9 vibrotactile motors in a 3 X 3 grid, that navigates a user through complex environments, by drawing patterns on the forearm. Apart from communicating directions that help navigate people, the design language aims to communicate the complexity of indoor environments, such as going left vs. going up the stairs to the left vs. going down the stairs to the left. Through a process of iterative prototyping and testing with people, the result is a preliminary language for navigating pedestrians within the built environment. It also paves the way for designers to design experiences beyond the audiovisual.
Ruling out 3 keV warm dark matter using 21 cm-EDGES data

description: Weakly interacting cold dark matter (CDM) particles, which are otherwise extremely successful in explaining various cosmological observations, exhibit a number of problems on small scales. One possible way of solving these problems is to invoke (so-called) warm dark matter (WDM) particles with masses $m_x \sim$ keV. Since the formation of structure is delayed in such WDM models, it is natural to expect that they can be constrained using observations related to the first stars, e.g., the 21 cm signal from cosmic dawn. In this work, we use a detailed galaxy formation model, Delphi, to calculate the 21 cm signal at high-redshifts and compare this to the recent EDGES observations. We find that while CDM and 5 keV WDM models can obtain a 21 cm signal within the observed redshift range, reproducing the amplitude of the observations requires the introduction of an excess radio background. On the other hand, WDM models with $m_x \leq 3$ keV can be ruled out since they are unable to match either the redshift range or the amplitude of the EDGES signal, irrespective of the parameters used. Comparable to values obtained from the low-redshift Lyman Alpha forest, our results extend constraints on the WDM particle to an era inaccessible by any other means; additional forthcoming 21 cm data from the era of cosmic dawn will be crucial in refining such constraints.

The fibers should be radiation hard for 1 Mrad/year. Corresponding prototypes have been build and tested at a 3 GeV electron beam at DESY. Preliminary results of these tests indicate that the design goal for the detector is reached.

Attachment preferences and corpus frequencies in PP ambiguities: Evidence from Greek
Creators: name: Katsika, Kalliopi
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2011
Subjects: attachment; corpus; frequency; prepositions; Prepositional Phrases; sentence comprehension; structural ambiguity

description: The present study investigates the extent to which frequency affects Greek native speakers’ attachment preferences for structures involving ambiguous Prepositional Phrases. Analyses of samples from a written and a spoken Greek corpus were conducted in order to examine the frequency patterns of PP attachment in Greek. The results of the corpus analyses were contrasted to the findings of an on-line self-paced reading task which investigated the processing of ambiguous PPs. The results indicate that corpus frequencies correspond to parsing decisions on a coarse-grained (syntactic) level, and to a lesser extent on a fine-grained (lexical) level of analysis.

description: This letter investigates the molecular dynamics of inelastic disks without external forcing. By introducing a new observation frame with a rescaled time, we observe the virtual steady states converted from asymptotic energy dissipation processes. System behavior in the thermodynamic limit is carefully investigated. It is found that a phase transition with symmetry breaking occurs when the magnitude of dissipation is greater than a critical value.

Light Sterile Neutrino and Low Scale Left-Right Symmetry in D-brane inspired $SU(4)_C \times SU(2)_L \times SU(2)_R$

description: Motivated by the ongoing searches for new physics at the LHC, we explore the low energy consequences of a D-brane inspired $ SU(4)_C\times SU(2)_L \times SU(2)_R$ (4-2-2) model. The Higgs sector consists of an $SU(4)$ adjoint, a pair $H+\bar H$ in $(4,1,2)+(\bar 4,1,2)$, and a bidoublet field in $h(1,2,2)$. With the $SU(4)$ adjoint the symmetry breaks to a left-right symmetric $SU(3)_C\times U(1)_{B-L} \times SU(2)_L \times SU(2)_R$ model. A missing partner mechanism protects the $SU(2)_R$ Higgs doublets in $H,\bar H$, which subsequently break the symmetry to the Standard Model at a few TeV scale. An inverse seesaw mechanism generates masses for the observed neutrinos and also yields a sterile neutrino which can play the rôle of dark matter if its mass lies in the keV range. Other phenomenological implications including proton decay are briefly discussed.

description: Science fiction is a literary genre whose elements of estrangement and cognition – modeled on the appearance of the modern sciences paradigms – are essential and sufficient elements. From its origins to the present day, its importance and influence in society is strengthening and its relevance as a social critic is increasingly recognized. Among the authors of the genre, Isaac Asimov stands out as one of the most important of the twentieth century and the Foundation series as one of the most representative part of his work. With a special emphasis on the relationship between the original trilogy, written and published between 1941 and 1953, with its 1982 sequel, Foundation´s Edge, this research combines a Bakhtinian analysis of discourse and discussions on Technology and Society to problematize the evolution of the tension between determinism and emancipation represented in Psychohistory, novum used by Asimov to construct his fictional world. From the editorial and thematic context, the analyzes indicated that the narrative structures, style and language choices, and the construction of the chronotopes of the romances establish a dialogue with the sociohistorical evolution of Science Fiction and the theoretical-critical problematizations of the studies on Science, Technology Society field. It has also been identified that the positions resulting from these dialogues between context, arguments and narrative elements are a dynamic and dialogic construction that privileges the thought emancipation its recipient to the detriment of the monological attempts to silence divergent positions eventually observed. We believe that this research corroborated the initial hypothesis that the vision on Science and Technology expressed in Asimov’s analyzed works is responsive to social transformations with an increasing critical character against the technological determinism that consolidates in the form of confrontation between political and technical systems in Foundation’s Edge.

Helium Suppression in Impulsive Solar Energetic-Particle Events

Publisher: name: arXiv
Year: 2018
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: We have studied the element abundances and energy spectra of the small "He-poor" impulsive solar energetic-particle (SEP) events, comparing them with other impulsive SEP events with more-normal abundances of He. He-poor events can have abundances as low as He/O ~ 2, while both impulsive and gradual SEP events usually have source abundances of 30 < He/O < 100 with mean values of 50 - 60. He/C ratios are not only low, but often decrease with energy in He-poor events. Abundance enhancement patterns of other elements with atomic numbers 6 < Z < 56, and likely values of their mass-to-charge ratios A/Q, are generally unaltered in He-poor events, as are the probable source-plasma temperatures of 2.5 - 3.2 MK for all impulsive SEP events. One He-poor event is also an example of a rarer C-poor event with C/O = 0.08 +- 0.04, sup-pressed by a factor over 5 from the mean. We discuss suggestions of a possible A/Q threshold during acceleration and of the sluggish ionization of He entering the corona, because of its uniquely high first ionization potential (FIP), but the suppression of He and the decline of He/C with energy is difficult to explain if both He and C are fully ionized with A/Q = 2 as expected at 2.5 - 3.2 MK. Although less dramatic, a possible excess enhancement of Ne in some impulsive SEP events is also considered. Possible causes of the large ~30% spectral and abundance variations in impulsive events are also discussed. However, the physics of the He-poor events remains a mystery.

Testing non-classicality with exact Wigner currents for an anharmonic quantum system

description: Phase-space features of the Wigner flow for an anharmonic quantum system driven by the harmonic oscillator potential modified by the addition of an inverse square (one-dimension Coulomb-like) contribution are analytically described in terms of Wigner functions and Wigner currents. Reporting about three correlated continuity equations which quantify the flux of quantum information in the phase-space, the non-classicality profile of such an anharmonic system can be consistently obtained in terms of the fluxes of {\em probability}, {\em purity} and {\em von Neumann-like entropy}. Considering that quantum fluctuations can be identified from distortions over the classical regime, they can be quantified through the above-mentioned information fluxes whenever some {\em classically bounded} volume of the phase-space is selected. Our results suggest that the Wigner flow approach works as a probe of quantumness and classicality for a large set of anharmonic quantum systems driven by quantum wells.

description: We show that regularizing divergent integrals is crucially important when applied to the loop diagrams corresponding to quantum corrections to the coupling of the ``gravitational" scalar field due to the interaction among matter fields. We use the method of continuous spacetime dimensions to demonstrate that WEP is a robust property of the Brans-Dicke theory beyond the classical level, hence correcting our previous assertion of the contrary. The same technique can be used to yield the violation of WEP when applied to the scale-invariant theory, thus providing another reason for expecting fifth- force-type phenomena.

In this paper it is proposed to look for coherence properties of incoming light in a manner that can distinguish against atomic emission lines. The use of photon sensitive detectors and a modulating asymmetric interferometer has been modelled. The results suggest that the sensitivity of detection for continuous laser sources would be better than current spectroscopic approaches, with detection thresholds of $

description: The ground state phase diagram of the 1D Hubbard chain with pair-hopping interaction is studied. The analysis of the model is performed using the continuum-limit field theory approach and exact diagonalization studies. At half-filling the phase diagram is shown to consist of two superconducting states with Cooper pair center-of-mass momentum Q=0 (BCS-η_0 phase) and Q=π(η_π-phase) and four insulating phases corresponding to the Mott antiferromagnet, the Peierls dimerized phase, the charge-density-wave (CDW) insulator as well as an unconventional insulating phase characterized by the coexistence of a CDW and a bond-located staggered magnetization. Away from half-filling the phase diagram consists of the superconducting BCS-η_0 and η_πphases and the metallic Luttinger-liquid phase. The BCS-η_0 phase exhibits smooth crossover from a weak-coupling BCS type to a strong coupling local-pair regime. The η_πphase shows properties of the doublon (zero size Cooper pair) superconductor with Cooper pair center-of-mass momentum Q=π. The transition into the η_π- paired state corresponds to an abrupt change in the groundstate structure. After the transition the conduction band is completely destroyed and a new η_π-pair band corresponding to the strongly correlated doublon motion is created.

description: We present the result of an \textit{ab initio} search for new Dirac materials among inverse perovskites. Our investigation is focused on the less studied class of lanthanide antiperovskites containing heavy $f$-electron elements in the cation position. Some of the studied compounds have not yet been synthesized experimentally. Our computational approach is based on density functional theory calculations which account for spin-orbit interaction and strong correlations of the $f$-electron atoms. We find several promising candidates among lanthanide antiperovskites which host bulk Dirac states close to the Fermi level. Specifically, our calculations reveal massive three-dimensional Dirac states in materials of the class A$_3$BO, where A=Sm, Eu, Gd, Yb and B=Sn, Pb. In materials with finite magnetic moment, such as Eu$_3$BO (B=Sn, Pb), the degeneracy of the Dirac nodes is lifted, leading to appearance of Weyl nodes.

Referential agreement in Modern Greek coordinate nouns
Creators: name: Kazana, Despina
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2011
Subjects: syntactic agreement; semantic agreement; contextually referred noun; referential agreement

description: In most languages, gender agreement in predicate argument coordinate nouns can be either syntactic or semantic. In Modern Greek (MG), the analysis of the data showed that a third type of gender agreement is also found motivated by a contextually referred noun and known as referential agreement. This type of agreement occurs in specific discourse conditions where native speakers bring into the context an implied noun and the predicative adjective/participle agrees with the agreement features of that noun. The analysis of the present phenomenon could be viewed from an ontological perspective.

Mixing-induced CP Asymmetries in Radiative B Decays in and beyond the Standard Model

description: In the Standard Model (SM) the photon in radiative $\bar B^0$ and $\bar B_s$ decays is predominantly left-handed. Thus, mixing induced CP asymmetries in $b\to sγ$ and $b\to dγ$ are suppressed by $m_s/m_b$ and $m_d/m_b$, respectively, and are very small. In many extensions of the SM, such as the left-right symmetric model (LRSM), SU(2)xU(1) models with exotic fermions and SUSY, the amplitude of right-handed photons grows proportional to the virtual heavy fermion mass, which can lead to large asymmetries. As an example, in the LRSM, asymmetries larger than 50% are possible even when radiative decay rate measurements agree with SM predictions.

description: Science fiction is a literary genre whose elements of estrangement and cognition – modeled on the appearance of the modern sciences paradigms – are essential and sufficient elements. From its origins to the present day, its importance and influence in society is strengthening and its relevance as a social critic is increasingly recognized. Among the authors of the genre, Isaac Asimov stands out as one of the most important of the twentieth century and the Foundation series as one of the most representative part of his work. With a special emphasis on the relationship between the original trilogy, written and published between 1941 and 1953, with its 1982 sequel, Foundation´s Edge, this research combines a Bakhtinian analysis of discourse and discussions on Technology and Society to problematize the evolution of the tension between determinism and emancipation represented in Psychohistory, novum used by Asimov to construct his fictional world. From the editorial and thematic context, the analyzes indicated that the narrative structures, style and language choices, and the construction of the chronotopes of the romances establish a dialogue with the sociohistorical evolution of Science Fiction and the theoretical-critical problematizations of the studies on Science, Technology Society field. It has also been identified that the positions resulting from these dialogues between context, arguments and narrative elements are a dynamic and dialogic construction that privileges the thought emancipation its recipient to the detriment of the monological attempts to silence divergent positions eventually observed. We believe that this research corroborated the initial hypothesis that the vision on Science and Technology expressed in Asimov’s analyzed works is responsive to social transformations with an increasing critical character against the technological determinism that consolidates in the form of confrontation between political and technical systems in Foundation’s Edge.

The Syntax-Information Component Interface: On the Properties of V-initial Orders in Greek
Creators: name: Kechagias, Axiotis
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2011
Subjects: new and old information; focus; presentational mapping; cartography

description: In this paper I argue that what regulates the (in-)felicity of the V-initial orders in MG has little to do with the oldness/novelty of referents of lexical items, or with possible restrictions on the syntax of discourse functions per se. Rather, I show that V-initial orders in MG fulfil independent requirements which run on the Syntax-IC Interface.

description: The advantages and possibilities of fiber technology for the detection of particles in 500 GeV e+e- reactions are considered. It is suggested to build a fast trigger which could be used also for intermediate tracking. A fiber preshower in front of the electromagnetic calorimeter would allow to identify electrons and photons with a space precision better than 0.1 mm.

The relationship between stress and syntax in German

Publisher: name: Selected papers on theoretical and applied linguistics
Year: 2011
Subjects: syntax; stress; focus; givenness; German

description: The following paper is intended to show how metrical structure of German verb-final sentences can be derived from syntactic and information-structural cues by taking the syntactic relationship and the information status of adjacent syntactic constituents into consideration. It will be argued that the syntactic structure has to be supplemented by focus features rather than by givenness features and that focus features need to be restricted to foreground domains to derive the correct stress pattern.

description: Since the appearance of electronic dictionaries, ways of obtaining dictionary information have changed. Paper dictionaries seem to be losing popularity among EFL (English as a Foreign Language) students over their electronic counterparts. The present survey was undertaken in this relatively recent area of lexicography and is in relation to the content and quality of English to English online pronunciation dictionaries. It provides an overview of free online dictionaries concerning the representation of their phonetic content and their user-friendliness.

description: We consider the momentum-space 3-point correlators of currents, stress tensors and marginal scalar operators in general odd-dimensional conformal field theories. We show that the flat space limit of these correlators is spanned by gauge and gravitational scattering amplitudes in one higher dimension which are related by a double copy. Moreover, we recast three-dimensional CFT correlators in terms of tree-level Feynman diagrams without energy conservation, suggesting double copy structure beyond the flat space limit.
