description: It is shown that a Lagrangian, describing the interaction of the gravitation field with the dilaton and the antisymmetric tensor in arbitrary dimension spacetime, admits an isotropic p-brane solution consisting of three blocks. Relations with known p-brane solutions are discussed. In particular, in ten-dimensional spacetime the three-block p-brane solution is reduced to the known solution, which recently has been used in the D-brane derivation of the black hole entropy.

description: Totally asymmetric simple exclusion process (TASEP) was originally introduced as a model for the traffic-like collective movement of ribosomes on a messenger RNA (mRNA) that serves as the track for the motor-like forward stepping of individual ribosomes. In each step, a ribosome elongates a protein by a single unit using the track also as a template for protein synthesis. But, pre-fabricated, functionally competent, ribosomes are not available to begin synthesis of protein; a subunit directionally scans the mRNA in search of the pre-designated site where it is supposed to bind with the other subunit and begin the synthesis of the corresponding protein. However, because of `leaky' scanning, a fraction of the scanning subunits miss the target site and continue their search beyond the first target. Sometimes such scanners successfully identify the site that marks the site for initiation of the synthesis of a different protein. In this paper, we develop an exclusion model, with three interconvertible species of hard rods, to capture some of the key features of these biological phenomena and study the effects of the interference of the flow of the different species of rods on the same lattice. More specifically, we identify the meantime for the initiation of protein synthesis as appropriate mean {\it first-passage} time that we calculate analytically using the formalism of backward master equations. In spite of the approximations made, our analytical predictions are in reasonably good agreement with the numerical data that we obtain by performing Monte Carlo simulations. We also compare our results with a few experimental facts reported in the literature and propose new experiments for testing some of our new quantitative predictions.

description: The extended minimal geometric deformation (EMGD) is employed on the fluid membrane paradigm, to describe compact stellar objects as Bose--Einstein condensates (BEC) consisting of gravitons. The black hole quantum portrait, besides deriving a preciser phenomenological bound for the fluid brane tension, is then scrutinized from the point of view of the configurational entropy. It yields a range for the critical density of the EMGD BEC, whose configurational entropy has global minima suggesting the configurational stability of the EMGD BEC.

The maximum luminosity of fast radio bursts

Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: Under the assumption that fast radio bursts (FRBs) are from coherent curvature emission powered by the dissipation of magnetic energy in the magnetosphere of neutron stars, we predict a maximum isotropic equivalent luminosity of (~2x10^{47} erg/s) min(ρ^2, Bρ^{4/3}ν^{-2/3}), where ρ is the curvature radius of the magnetic field lines near the source region in units of 10 km, B is the local magnetic field strength in units of 10^{16} G, and ν is the FRB wave frequency in units of GHz. This is because the electric field responsible for accelerating the radiating particles becomes close to the quantum critical field strength and is then quickly shielded by Schwinger pairs within a nano-second. Future observations should be able to confirm this cut-off luminosity and hence provide a unique probe of the source location and magnetic field strength. We discuss how the maximum luminosity affects the observed flux distributions for repeating bursts from the same object and for the entire FRB population.

description: The covariant phase space technique is a powerful formalism for understanding the Hamiltonian description of covariant field theories. However, applications of this technique to problems involving subregions, such as the exterior of a black hole, have heretofore been plagued by boundary ambiguities. We provide a resolution of these ambiguities by directly computing the symplectic structure from the path integral, showing that it may be written as a contour integral around a partial Cauchy surface. This result has implications for gauge symmetry and entanglement.

An Electropalatographic study of Vowel-to-Consonant coarticulation in Greek
Creators: name: Nicolaidis, Katerina
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1997

description: The technique of electropalatography (Reading EPG system) is used in this study to examine coarticulatory effects from vowels on consonants involving different degrees of articulatory constraint in their production. The relationship between random (i.e., token-to- token) variability, degree of articulatory constraint and coarticulatory propensity is investigated. The speech material consisted of real words containing Vowel-Consonant-Vowel (VCV) sequences with V = /i, a/ and C = /p, t, s/. The results confirmed an inverse relationship between coarticulatory propensity and articulatory constraint during the production of the consonant. Coarticulatory effects on the tongue dorsum were found to decrease in the order p>t>s, i.e., from the least to the most constrained gesture. Differential behaviour was observed for the tongue tip/blade and suggested that coarticulatory variability is also constrained by language specific requirements.

description: No abstracts are to be cited without prior reference to the author.Annual growth-increment widths measured in marine organism hard structures provide an integrated measure of an animal’s growth rate over its life span and when related to environmental variability reveal evidence for a biophysical response. Evidence for a functional response between climate variability and animal growth is strengthened when such a response is seen across diverse taxa under the influence of physical processes in a given ecosystem. In this study, we evaluated the functional response between climate variability on the growth rates of a slope and nearshore rockfish species (Sebastes spp.) in both the California Current (CC) and Alaska Coastal Current (ACC) ecosystems. Exactly dated growth increment data were analyzed with hierarchical Bayesian methods that modeled rockfish growth as intrinsic age- and extrinsic climate-related effects, including sea surface temperature (SST), coastal upwelling, multivariate Enso index (MEI), and Pacific Decadal Oscillation (PDO). Rockfish growth in the CC system responded positively to upwelling derived production characterized by higher than average growth during years with higher coastal upwelling and cool water. In contrast, rockfish growth in the ACC responded favorably to a combination of winter mixing followed by strong spring/summer stratification characteristic of increased growth during years with warmer water temperatures and relaxed spring downwelling. Slope rockfish showed much less growth variability than compared to nearshore rockfish indicating that low frequency growth effects may be more strongly coupled to basin-scale processes such as MEI. These results suggest that biophysical coupling between physical factors and rockfish growth likely occurs at several different spatial and temporal scales. Moreover the approach presented represents a more general statistical methodology for the analysis of growth increment data because it partitions and estimates both the intrinsic age and extrinsic climate effects on growth variability.

description: Time resolved measurements of quasiparticle (QP) relaxation dynamics on the femtosecond timescale are reported as a function of temperature and doping in YBa2Cu3O(7-x) for (0.48 < x < 0.1). In the underdoped state (x > 0.15), there is no evidence for any changes in the low-energy gap structure at Tc from either photoinduced QP absorption or QP relaxation time data. In combination with the sum rule, this implies the existence of pre-formed pairs up to a much higher temperature T*. Near x = 0.1 a rapid cross-over is observed, to a state where the QP recombination time diverges and the photoinduced QP density falls to zero at Tc, indicating the existence of a temperature-dependent superconducting gap which closes at Tc.

description: It is shown that neutrino mixing angles which are consistent with current experimental observations may be naturally obtained in a Pati-Salam model constructed from intersecting D6 branes on a $T^6/(Z_2 \times Z_2)$ orientifold. The Dirac mass matrices in the model are naturally the same as those which are obtained by imposing a $\mathbf{Δ(27)}$ flavor symmetry, which allows for near-tribimaximal mixing in the neutrino sector. In addition, it is possible to obtain the correct mass matrices for quarks and charged leptons, as well as nearly the correct CKM matrix. An RGE analysis of the neutrino mass parameters, including the seesaw mechanism assuming a specific form for the right-handed neutrino mass matrix is performed, and it is found that the neutrino mixing angles at the electroweak scale are $θ_{12}=35.0^{\circ}$, $θ_{23}=47.1^{\circ}$, and $θ_{13}=8.27^{\circ}$. In addition,the neutrino mass-squared differences are found to be $Δm^2_{32} = 0.00252$ eV$^2$ and $Δm^2_{21} = 0.0000739$ eV$^2$ with $m_1=0.0146$ eV, $m_2=0.0170$ eV, and $m_3=0.0530$ eV.

description: Some low-mass white-dwarf (LMWD) stars with H atmospheres show long-period g-mode pulsations, comprising the class of pulsating WDs called extremely low-mass variable (ELMV) stars. It is generally believed that these stars have thick H envelopes. However, from stellar evolution considerations, the existence of LMWDs with thin H envelopes is also possible. We present a thorough asteroseismological analysis of ELMV stars based on a complete set of fully evolutionary models that represents low-mass He-core WD stars harboring a range of H envelope thicknesses. Although there are currently nine ELMVs, here we only focus on those that exhibit more than three periods and whose periods do not show significant uncertainties. We considered g-mode adiabatic pulsation periods for low-mass He-core WD models with $M_*$ in the range [0.1554-0.4352]$M_{\odot}$, $T_{\rm eff}$ in the range [6000-10000]K, and H envelope thicknesses in the range -5.8

Integrable S matrix, mirror TBA and spectrum for the stringy $\text{AdS}_{3}\times\text{S}^3\times\text{S}^3\times\text{S}^1$ WZW model

description: We compute the tree-level bosonic S matrix in light-cone gauge for superstrings on pure-NSNS $\text{AdS}_{3}\times\text{S}^3\times\text{S}^3\times\text{S}^1$. We show that it is proportional to the identity and that it takes the same form as for $\text{AdS}_{3} \times \text{S}^3\times\text{T}^4$ and for flat space. Based on this, we make a conjecture for the exact worldsheet S matrix and derive the mirror thermodynamic Bethe ansatz (TBA) equations describing the spectrum. Despite a non-trivial vacuum energy, they can be solved in closed form and coincide with a simple set of Bethe ansatz equations - again much like $\text{AdS}_{3}\times\text{S}^3\times\text{T}^4$ and flat space. This suggests that the model may have an integrable spin-chain interpretation. Finally, as a check of our proposal, we compute the spectrum from the worldsheet CFT in the case of highest-weight representations of the underlying Kač-Moody algebras, and show that the mirror-TBA prediction matches it on the nose.

Initial Direct Objects in English Formal and Semantic Characteristics and Discourse Functions
Creators: name: Misic Ilic, Biljana
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1997

description: The paper presents the results of a corpus-based study of topicalization, defined in the narrowest sense as moving of the direct object to the initial position in declarative sentences in written English. The analysis starts with examining formal and semantic characteristics of fronted direct objects and the sentences in which they appear, and then proceeds beyond the sentence level, in an attempt to identify various discourse functions of topicalization. Depending primarily on the form of fronted direct objects (NPs of various complexity and nominal clauses) and the type of the relationship of their referents to previously evoked discourse entities, it is possible to note that different functions of topicalization are realised in various degrees. Although sometimes viewed merely as a syntactic construction which marks given information, thereby enabling easier message interpretation to the hearer/reader, topicalization can be considered also from the point of view of its textually-cohesive contribution. As a means of dissociating the functions of Theme, Actor, and Subject, it makes the marked Theme the starting point of the message, giving it a particular status in relation to the surrounding discourse. Among semantic and pragmatic functions, common for all preposings, marking the referent of the topicalized DO as being in a salient set relation to another discourse entity has shown to be very significant. Finally, it is also possible to view topicalization as a stylistic and rhetorical device by which the speaker/writer re-orders the position of sentence elements in order to achieve a particular effect and, in a way, 'impose' the desired interpretation.

description: Superunification underwent a major paradigm shift in 1984 when eleven-dimensional supergravity was knocked off its pedestal by ten-dimensional superstrings. This last year has witnessed a new shift of equal proportions: perturbative ten-dimensional superstrings have in their turn been superseded by a new non-perturbative theory called {\it $M$-theory}, which describes supermembranes and superfivebranes, which subsumes all five consistent string theories and whose low energy limit is, ironically, eleven-dimensional supergravity. In particular, six-dimensional string/string duality follows from membrane/fivebrane duality by compactifying $M$-theory on $S^1/Z_2 \times K3$ (heterotic/heterotic duality) or $S^1 \times K3$ (Type $IIA$/heterotic duality) or $S^1/Z_2 \times T^4$ (heterotic/Type $IIA$ duality) or $S^1 \times T^4$ (Type $IIA$/Type $IIA$ duality).

description: We monitor dynamic rupture propagation during laboratory stick-slip experiments performed on saw-cut Westerly granite under upper crustal conditions (10-90 MPa). Spectral analysis of high-frequency acoustic waveforms provided evidence that energy radiation is enhanced with stress conditions and rupture velocity. Using acoustic recordings bandpass filtered to 400-800 kHz (7-14 mm wavelength) and highpass filtered above 800 kHz, we back projected high-frequency energy generated during rupture propagation. Our results show that the high-frequency radiation originates behind the rupture front during propagation and propagates at a speed close to that obtained by our rupture velocity inversion. From scaling arguments, we suggest that the origin of high-frequency radiation lies in the fast dynamic stress-drop in the breakdown zone together with off-fault co-seismic damage propagating behind the rupture tip. The application of the back-projection method at the laboratory scale provides new ways to locally investigate physical mechanisms that control high-frequency radiation.

description: An exactly soluble non-perturbative model of the pure gauge QCD is derived as a weak coupling limit of the lattice theory in plaquette formulation. The model represents QCD as a theory of the weakly interacting field strength fluxes. The area law behavior of the Wilson loop average is a direct result of this representation: the total flux through macroscopic loop is the additive (due to the weakness of the interaction) function of the elementary fluxes. The compactness of the gauge group is shown to be the factor which prevents the elementary fluxes contributions from cancellation. There is no area law in the non-compact theory.

description: Ancient Greek prepositions -though not occurring by themselves in Modern Greek as free elements (with a few exceptions)- are extremely productive when attaching to verbal or nominal stems (i.e., nominalizations). Our basic issue, in the present study, is that these prepositions function as lexically attached prefixes in the sense that (a) they follow lexical word-formation processes, i.e., word-formation rules (WFRs), (b) they are semantically noncompositional, and (c) the verbal or nominal stems when combined with them become lexically derived composites. For example, the archaic prepositions apo, ek, en, pro, ana, meta, epi and hypo, all prefix to a stem such as trop-

Attitudes towards the Greek Cypriot Dialect: Sociocultural implications

Year: 1997

description: Contrary to linguistic evidence, people still believe that some languages are more "precise", "beautiful" and "expressive" than other languages and that some dialects are "inferior", "inexpressive" and "incomplete" than their corresponding standard or official languages. Many studies have been carried out and several techniques have been employed in order to examine peoples' attitudes towards languages and varieties of languages. Some of the most common techniques include surveys and questionnaires, carrying out interviews, recording natural conversations and employing experimental manipulations. In the present study an experimental attempt was made to investigate Greek Cypriots' attitudes toward their native language, the Cypriot dialect, by employing the matched-guise technique. Twenty-two first-year Greek Cypriot students attending the University of Cyprus were selected to serve as subjects (judges) and evaluate the qualities of several speakers using the Cypriot dialect on one occasion (one guise) and Standard Modern Greek (SMG) on another occasion (the other guise). Judges' evaluation took the form of filling-in a table that included twelve traits such as kindness, intelligence, sincerity, depedability and sense of humor. The obtained results show that the SMG guises were rated more favorably than the Cypriot guises and an attempt is made to explore the sociocultural implications of these findings

Variability in Interlanguage: a case study
Creators: name: Ioannou-Georgiou, Sophia
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1997

description: This paper presents a study dealing with variability in interlanguage. Based on the data provided by the study, it investigates the factors that can explain the variability found in a learner's interlanguage and also tries to provide evidence towards answering the question of whether interlanguage variability is systematic or not. A definition of variability is firstly discussed and after referring to the ways that variability can influence interlanguage, the various existing explanations of the phenomenon are presented. The case study is a detailed analysis of a migrant woman's interlanguage. At a first stage the analysis concentrates on whether the subject's interlanguage is systematic or not. At a second stage it tries to find which, if any, of the existing explanations of variability explain the variability found in the subject's interlanguage. The results of the analysis show that although the learner has formed a personal rule system for negation, other areas of her interlanguage cannot be explained by variable rules. This led to the assumption that although some parts of interlanguage are governed by a variable rule system, others are not. There was therefore a non-systematicity evident in the learner's interlanguage which contradicts Ellis' (1985) economy principle, Huebner's (1985) position that a learner must make functional distinctions and employ separate linguistic forms to express each function in order to communicate, as well as Andersen's "one function-one form" hypothesis. Nevertheless, a different kind of systematicity became evident in the learner's interlanguage that can only be explained by the existence of discourse domains (Selinker & Douglas, 1985).

Cut-off for sandpiles on tiling graphs
Creators: name: Hough, Robert
name: Son, Hyojeong
Publisher: name: arXiv
Year: 2019
Subjects: subject: Probability (math.PR)
subject: FOS: Mathematics

description: Sandpile dynamics are considered on graphs constructed from periodic plane and space tilings by assigning a growing piece of the tiling either torus or open boundary conditions. A general method of obtaining the Green's function of the tiling is given, and a total variation cut-off phenomenon is demonstrated under general conditions. It is shown that the boundary condition does not affect the mixing time for planar tilings, nor does it change the asymptotic mixing time for the cubic lattice $\zed^d$ for all sufficiently large $d$. In a companion paper, computational methods are used to demonstrate that the mixing time is altered for the $\Dfour$ lattice in dimension 4.

description: We study the flow of a weakly-interacting Bose-Einstein condensate around an obstacle by numerical solution of the Gross-Pitaevskii equation. We observe vortex emission and the formation of bow waves leading to pressure drag. We compare the drag law with that of an ideal Bose gas, and show that interactions reduce the drag force. This reduction can be explained in terms of a `collisional screening' of the obstacle.

description: We train a set of Restricted Boltzmann Machines (RBMs) on one- and two-dimensional Ising spin configurations at various values of temperature, generated using Monte Carlo simulations. We validate the training procedure by monitoring several estimators, including measurements of the log-likelihood, with the corresponding partition functions estimated using annealed importance sampling. The effects of various choices of hyper-parameters on training the RBM are discussed in detail, with a generic prescription provided. Finally, we present a closed form expression for extracting the values of couplings, for every $n$-point interaction between the visible nodes of an RBM, in a binary system such as the Ising model. We aim at using this study as the foundation for further investigations of less well-known systems.

Patterns of code - alternation among second - generation Greeks in Brussels, Belgium
Creators: name: Hatzidaki, Aspassia
Publisher: name: Selected papers on theoretical and applied linguistics
Year: 1997

description: Following a trend observed in many immigrant communities, bilingual second-generation Greeks in Brussels use the ethnic language to a large extent with parents but rarely with siblings and peers (Hatzidaki 1994). However, it is suggested that, due to many factors, there is considerable variation in their use of Greek and French. This paper presents the results of a study on code-alternation patterns among second-generation Greeks in Brussels (Hatzidaki 1994) with particular emphasis οn the importance of their social networks (cf. Milroy 1987) for the observed intra-generational variation.

Year: 1997

description: Ιn this paper Ι claim that Greek is a lexical accent system and Ι introduce a theoretical framework for its accentual analysis. Ιn systems of this type morphemes have to be specified in the lexicon as accented οr unaccented. Words composed of unaccented morphemes are stressed by the default rule. Ιn the presence of more than one mark within a word, the lexical specification of the stem prevails.

description: Context. We introduce a model for including accelerated particles in pure magnetohydrodynamics (MHD) simulations of the solar atmosphere. Aims. We show that the method is viable and produces results that enhance the realism of MHD simulations of the solar atmosphere. Methods. The acceleration of high-energy electrons in solar flares is an accepted fact, but is not included in the most advanced 3D simulations of the solar atmosphere. The effect of the acceleration is not known, and here we introduce a simple method to account for the ability of the accelerated electrons to move energy from the reconnection sites and into the dense transition zone and chromosphere. Results. The method was only run for a short time and with low reconnection energies, but this showed that the reconnection process itself changes, and that there is a clear effect on the observables at the impact sites of the accelerated electrons. Further work will investigate the effect on the reconnection sites and the impact sites in detail.

Subjects: subject: Pattern Formation and Solitons (nlin.PS)
subject: FOS: Physical sciences

description: The dynamical behavior resulting from an initial discontinuity in focusing media is investigated using a combination of numerical simulations and Whitham modulation theory for the focusing nonlinear Schrodinger equation. Initial conditions with a jump in either or both the amplitude and the local wavenumber are considered. It is shown analytically and numerically that the space-time plane divides into expanding domains in which the solution is described by a slow modulation of genus-zero, genus-one or genus-two solutions, their precise arrangement depending on the specifics of the initial datum

description: We report on a novel non-linear electric field effect in the conductivity of disordered conductors. We find that an electric field gives rise to dephasing in the particle-hole channel, which depresses the interference effects due to disorder and interaction and leads to a non-linear conductivity. This non-linear effect introduces a field dependent temperature scale $T_E$ and provides a microscopic mechanism for electric field scaling at the metal-insulator transition. We also study the magnetic field dependence of the non-linear conductivity and suggest possible ways to experimentally verify our predictions. These effects offer a new probe to test the role of quantum interference at the metal-insulator transition in disordered conductors.

description: We present a study of 16 HI-detected galaxies found in 178 hours of observations from Epoch 1 of the COSMOS HI Large Extragalactic Survey (CHILES). We focus on two redshift ranges between 0.108 <= z <= 0.127 and 0.162 <= z <= 0.183 which are among the worst affected by radio frequency interference (RFI). While this represents only 10% of the total frequency coverage and 18% of the total expected time on source compared to what will be the full CHILES survey, we demonstrate that our data reduction pipeline recovers high quality data even in regions severely impacted by RFI. We report on our in-depth testing of an automated spectral line source finder to produce HI total intensity maps which we present side-by-side with significance maps to evaluate the reliability of the morphology recovered by the source finder. We recommend that this become a common place manner of presenting data from upcoming HI surveys of resolved objects. We use the COSMOS 20k group catalogue, and we extract filamentary structure using the topological DisPerSE algorithm to evaluate the \hi\ morphology in the context of both local and large-scale environments and we discuss the shortcomings of both methods. Many of the detections show disturbed HI morphologies suggesting they have undergone a recent interaction which is not evident from deep optical imaging alone. Overall, the sample showcases the broad range of ways in which galaxies interact with their environment. This is a first look at the population of galaxies and their local and large-scale environments observed in HI by CHILES at redshifts beyond the z=0.1 Universe.

description: For an extreme charged black hole some scalars take on a fixed value at the horizon determined by the charges alone. We call them fixed scalars. We find the absorption cross section for a low frequency wave of a fixed scalar to be proportional to the square of the frequency. This implies a strong suppression of the Hawking radiation near extremality. We compute the coefficient of proportionality for a specific model.
