Molecular dynamics simulations on the melting, crystallization, and energetic reaction behaviors of Al/Cu core-shell nanoparticles
Authors: Cheng Xin-Lu , Zhang Jin-Ping , Zhang Hong , Zhao Feng
Published: August 2013

Using molecular dynamics simulations combined with the embedded atom method potential, we investigate the heating, cooling, and energetic reacting of core-shell structured Al-Cu nanoparticles. The thermodynamic properties and structure evolution during continuous heating and cooling processes are also investigated through the characterization of the total potential energy distribution, mean-square-distance and radial distribution function. Some behaviors related to nanometer scale Cu/Al functional particles are derived that two-way diffusion of Al and Cu atoms, glass phase formation for the fast cooling rate, and the crystal phase formation for the low cooling rate. Two-way atomic diffusion occurs first and causes the melting and alloying. In the final alloying structure, Cu and Al atoms mixed very well except for the outmost shell which has more Al atoms. For the investigation of the thermal stability and energetic reaction properties, our study show that a localized alloying reaction between the Al core and Cu shell is very slow when the initial temperature is lower than 600 K. But a two-stage reaction may occur when the initial temperature is 700 K. The reaction rate is determined by the solid-state diffusion of Al atoms in the Cu shell at the first stage, yet the reaction rate is much faster at the second stage, due to the alloying reaction between the liquid Al core and the Cu shell. At higher temperatures such as 800 K and 900 K, the alloying reaction occurs directly between the liquid Al core and the Cu shell.
Electronic and thermal transport in GeTe: A versatile base for thermoelectric materials
Authors: Levin E. M. , Besser M. F. , Hanus R.
Published: August 2013

GeTe is a narrow-band gap semiconductor, where Ge vacancies generate free charge carriers, holes, forming a self-dopant degenerate system with p-type conductivity, and serves as a base for high-performance multicomponent thermoelectric materials. There is a significant discrepancy between the electronic and thermal transport data for GeTe-based materials reported in the literature, which obscures the baseline knowledge and prevents a clear understanding of the effect of alloying GeTe with various elements. A comprehensive study including XRD, SEM, EDS, Seebeck coefficient, electrical resistivity, thermal conductivity, and 125Te NMR of several GeTe samples was conducted. Similar Seebeck coefficient and electrical resistivity are observed for all GeTe samples used showing that the concentration of Ge vacancies generating charge carriers is constant along the ingot. Very short 125Te NMR spin-relaxation time agrees well with high carrier concentration obtained from the Hall effect measurements. Our data show that at ∼700 K, GeTe has a very large power factor, 42 μWcm−1K−2, much larger than that of any high efficiency thermoelectric telluride at these temperatures. Electronic and thermal properties of GeTe are compared to PbTe, another well-known thermoelectric material, where free charge carriers, holes or electrons, are generated by vacancies on Pb or Te sites, respectively. Discrepancy in the data for GeTe reported in literature can be attributed to the variation in the Ge:Te ratio of solidified samples as well as to different conditions of measurements.
Interaction of a Mach 2.25 turbulent boundary layer with a fluttering panel using direct numerical simulation
Authors: Ostoich Christopher M. , Bodony Daniel J. , Geubelle Philippe H.
Published: August 2013

The interaction between a thin metallic panel and a Mach 2.25 turbulent boundary layer is investigated using a direct numerical simulation approach for coupled fluid-structure problems. The solid solution is found by integrating the finite-strain, finite-deformation equations of elasticity using a non-linear 3D finite element solver, while the direct numerical simulation of the boundary layer uses a finite-difference compressible Navier-Stokes solver. The initially laminar boundary layer contains low amplitude unstable eigenmodes that grow in time and excite traveling bending waves in the panel. As the boundary layer transitions to a fully turbulent state, with Reθ ≈ 1200, the panel's bending waves coalesce into a standing wave pattern exhibiting flutter with a final amplitude approximately 20 times the panel thickness. The corresponding panel deflection is roughly 25 wall units and reaches across the sonic line in the boundary layer profile. Once it reaches a limit cycle state, the panel/boundary layer system is examined in detail where it is found that turbulence statistics appear to be modified by the presence of the compliant panel, the effect of which is forgotten within one integral length downstream of the panel.
Optical critical coupling into highly confining metal-insulator-metal resonators
Authors: Manceau J.-M. , Zanotto S. , Sagnes I. , Beaudoin G. , Colombelli R.
Published: August 2013

We demonstrate controlled optical critical coupling into highly confining metal-insulator-metal grating-based resonators. We achieve the coupling—and hence the absorption—of more than 95% of the incoming photons in a gallium arsenide based system confined between a metallic ground plane and a metallic grating. The demonstration is given in the terahertz range of the electromagnetic spectrum, at 75 μm ≤ λ ≤ 120 μm, for a semiconductor core thickness of only 10 μm. It is valid, however, at any wavelength, upon linear scaling. The critical coupling regime is judiciously tuned by precise etching of the semiconductor material in between the metallic fingers. The experimental results are in accordance with the universal behaviour predicted by temporal coupled mode theory.
Communication: Constructing an implicit quantum mechanical/molecular mechanics solvent model by coarse-graining explicit solvent
Authors: Theel Kelly L. , Wen Shuhao , Beran Gregory J. O.
Published: August 2013

To avoid repeated, computationally expensive QM solute calculations while sampling MM solvent in QM/MM simulations, a new approach for constructing an implicit solvent model by coarse-graining the solvent properties over many explicit solvent configurations is proposed. The solvent is modeled using a polarizable force field that is parameterized in terms of distributed multipoles (electrostatics), polarizabilities (induction), and frequency-dependent polarizabilities (dispersion). The coarse-graining procedure exploits the ability to translate these properties to the center of each coarse-graining cell and average them over many solvent configurations before interacting them with the solute. A single coarse-grained QM/MM calculation of the interaction between a formamide solute and aqueous solvent reproduces the much more expensive average over many explicit QM/MM calculations with kJ/mol accuracy.

The anomalous appearance of a ferromagnetic moment in nominally antiferromagnetic nanoparticles has been known about since Néel, but never well understood. We present proof of the core/shell model of magnetism in antiferromagnetic NiO nanoparticles (NP) using neutron diffraction. Nickel oxide nanoparticles were produced in a large quantity by a novel continuous hydrothermal flow synthesis method. The antiferromagnetic nature of the nanoparticles allowed the structural and the magnetic diffraction peaks to be completely separated. Using both the microstructure option in "Fullprof" microstructure fitting suite and convolution techniques, we determined the NP consisted of an ordered antiferromagnetic core 5.2(2) nm in diameter surrounded by a disordered shell 0.7(2) nm thick. Further magnetic measurements showed that this disordered shell possess a significant polarisable magnetisation, up to a fifth that of pure nickel. They also indicate that two magnetic transitions occur between 400 and 10 K; around 350 K, there is a broad transition from paramagnetic to a form of superparamagnetism, then near 30 K there is a transition to a higher anisotropy state. Differences in field cooled and zero field cooled hysteresis loops were found, though with no evidence of exchange bias effects.

Muon tomography is a technique that uses cosmic ray muons to generate three dimensional images of volumes using information contained in the Coulomb scattering of the muons. Advantages of this technique are the ability of cosmic rays to penetrate significant overburden and the absence of any additional dose delivered to subjects under study above the natural cosmic ray flux. Disadvantages include the relatively long exposure times and poor position resolution and complex algorithms needed for reconstruction. Here we demonstrate a new method for obtaining improved position resolution and statistical precision for objects with spherical symmetry.
Near-infrared photoactive Cu2ZnSnS4 thin films by co-sputtering
Authors: Banavoth Murali , Dias Sandra , Krupanidhi S. B.
Published: August 2013

The thin films of Cu2ZnSnS4 (CZTS) were grown by co-sputtering further the structural, optical and electrical properties were analyzed and confirmed the CZTS phase formation. The photo response of CZTS in near IR photodectection has been demonstrated. The detector response was measured employing both the IR lamp and IR laser illuminations. The calculated growth and decay constants were 130 m sec and 700 m sec followed by the slower components upon lamp illumination. The external quantum efficiency of 15%, responsivity of 13 AW−1 makes CZTS a suitable candidate for the IR photodectection.
On Breathing and Geography: Explorations of Data Sonifications of Timespace Processes with Illustrating Examples from a Tidally Dynamic Landscape (Severn Estuary, UK)
Authors: Palmer (née Reiser) Michaela , Jones Owain
Published: August 2013

This paper consists of a discussion of data sonification—a procedure in which information gathered from systems such as bodies or environmental processes is analyzed and reprocessed into audio models, so aspects of the process generating the data (for example, emotional or tidal ebb and flow) can be apprehended by human senses. This serves various purposes relevant to geography. Firstly, it sets out the principles of sonification as a method, defining its basic principles and relating it to both qualitative and quantitative data. Secondly, it offers potential to geographic interests in process, times, rhythm, landscape, place, and more besides— ‘representing’ various aspects of processes that are beyond normal human apprehension, perhaps through register, duration, pitch, and so on. Thirdly, in the illustrating examples, which comprise sonifications of tides and other processes in the Severn Estuary, UK, it highlights possibilities of engaging local communities and stakeholders with the dynamics of landscapes such as tidal processes, which have significant implications for culture, economy, and ecology, as do other tidal and other process geographies elsewhere.
Poverty, Place, and Rurality: Material and Sociocultural Disconnections
Authors: Milbourne Paul
Published: August 2013

Recent academic critiques of poverty have pointed to the need to pay more attention to the relations between the material, social, and cultural dimensions of poverty as well as to the lived worlds of those on low income. This paper addresses these themes by exploring the ways in which people living in situations of material poverty discuss their everyday lives. Drawing on survey and interview materials from a recent study of poverty in rural Wales, the paper illustrates how people on low income construct their lives more in relation to their social and cultural worlds than to issues of low income and material deprivation. Key findings from the study reveal important disconnections between material and sociocultural aspects of rural poverty, with community belonging and attachment to landscape appearing more significant than material hardship and social exclusion within poor people's narratives of their everyday lives. Community belonging is also bound up with particular moral discourses of welfare and rurality that act to perpetuate situations of material poverty within rural places.
Not a Drama: Things Affect in Herbert Read's the Innocent Eye
Authors: Ashmore Paul
Published: August 2013

This paper attempts to rethink the role of things in the ongoing constitution of life. It seeks to build upon existing accounts of things in the social sciences where the measure of things is taken in their capacity to trigger an emotional response in a human subject, arguing that it is also necessary to consider things where they do not disrupt and are not registered emotionally. It is argued that things can be usefully considered as a continual series of affective ‘micro-shocks’ working to generate affective atmospheres. These premises are explored through a brief empirical excursion into an autobiographical account of childhood life, Herbert Read's The Innocent Eye (1933). Read's account is sensitive to the role of things in life and adopts what might be understood as a stance of ‘childlike wonder’ towards a world full of things, where the human-as-thing is in a state of becoming in the midst of these. The paper concludes by reflecting on the implications of this discussion for three key issues: first, the usefulness of understanding things as affective; second, the thing-ness of things beyond their emotional rendering; third, the importance of experimentation in the reception and narration of things for better accounting for the work done by things.
Visual Jitter Inhibits Roll Vection for an Upright Observer
Authors: Nakamura Shinji
Published: August 2013

It is widely known that visual jitter convoluted with an expanding optical flow can robustly enhance an observer's illusory perception of forward self-motion (eg Palmisano et al 2000 Perception29 57–67). In the present investigation I examine the effects of visual jitter on visually induced self-rotation (roll vection). The results showed that the strength of roll vection was decreased under conditions where the visual jitter was convoluted into the rotating visual stimulus. Although the extent of the decrement differed according to the amplitude and direction of the jitter, visual jitters in any direction with any amplitude can significantly reduce vection strength, at least under the conditions examined in the present experiment. The perceptual process underlying jitter effects on vection is discussed in the context of visuo-vestibular conflict in perception of self-motion.
Motion Illusions in Optical Art Presented for Long Durations are Temporally Distorted
Authors: Nather Francisco Carlos , Mecca Fernando Figueiredo , Bueno José Lino Oliveira
Published: August 2013

Static figurative images implying human body movements observed for shorter and longer durations affect the perception of time. This study examined whether images of static geometric shapes would affect the perception of time. Undergraduate participants observed two Optical Art paintings by Bridget Riley for 9 or 36 s (group G9 and G36, respectively). Paintings implying different intensities of movement (2.0 and 6.0 point stimuli) were randomly presented. The prospective paradigm in the reproduction method was used to record time estimations. Data analysis did not show time distortions in the G9 group. In the G36 group the paintings were differently perceived: that for the 2.0 point one are estimated to be shorter than that for the 6.0 point one. Also for G36, the 2.0 point painting was underestimated in comparison with the actual time of exposure. Motion illusions in static images affected time estimation according to the attention given to the complexity of movement by the observer, probably leading to changes in the storage velocity of internal clock pulses.
Tunable Organogelator from Alkyl-Polypeptide Diblock Prepared by Ring-Opening Polymerization
Authors: Chen Chongyi , Wu Decheng , Fu Wenxin , Li Zhibo
Published: August 2013

Three alkyl-polypeptide hybrid amphiphiles were synthesized by the ring-opening polymerization (ROP) of γ-(2-methoxyethoxy)esteryl-l-glutamate N-carboxyanhydride (l-EG1Glu NCA) using alkylamine, i.e. C6H13NH2, C14H29NH2, and C16H33NH2, as initiators. As-prepared alkyl-poly-l-EG1Glu hybrids were found to form clear organogels in several organic solvents at low concentration. FTIR and circular dichroism characterizations suggested that poly-l-EG1Glu formed a predominantly β-sheet conformation, which accounted for the gelation. Transmission electron and atomic force microscopy characterizations revealed that these copolymers formed nanoribbon structures in THF.
Corrigendum to: Assessing the effect of foliar moisture on the spread rate of crown fires
Authors: Alexander Martin E. , Cruz Miguel G.
Published: August 2013

This paper constitutes a digest and critique of the currently available information pertaining to the influence of live fuel or foliar moisture content (FMC) on the spread rate of crown fires in conifer forests and shrublands. We review and discuss the findings from laboratory experiments and field-based fire behaviour studies. Laboratory experimentation with single needles or leaves and small conifer trees has shown an unequivocal effect of FMC on flammability metrics. A much less discernible effect of FMC on crown fire rate of spread was found in the existing set of experimental crown fires carried out in conifer forests and similarly with the far more robust database of experimental fires conducted in shrubland fuel complexes. The high convective and radiant heat fluxes associated with these fires and the lack of appropriate experimental design may have served to mask any effect of FMC or live fuel moisture on the resulting spread rate. Four theoretical functions and one empirical function used to adjust rate of fire spread for the effect of foliar or live fuel moisture were also concurrently examined for their validity over a wide range of FMC conditions with varying outcomes and relevancy. None of these model functions was found suitable for use with respect to dead canopy foliage.
Dissociable effects of surprise and model update in parietal and anterior cingulate cortex

Published: August 2013

Significance

This study investigates the brain mechanisms by which people disregard their previous beliefs about their environment and start forming new beliefs. Surprising events are often a signal that one’s previous beliefs are no longer valid. Using brain imaging, we identified separate brain systems involved in dealing with the immediate consequences of surprise (i.e., reprogramming actions) and in updating one’s beliefs about the environment to predict future events accurately. We present a mathematical and neuroanatomical model of how brains adjust to change in their environment that may inform our understanding of neurological disorders in which this adjustment process fails.
ERK regulation of phosphodiesterase 4 enhances dopamine-stimulated AMPA receptor membrane insertion
Authors: Song Roy S. , Massenburg Ben , Wenderski Wendy , Jayaraman Vino , Thompson Lauren , Neves Susana R.
Published: August 2013

Significance

ERK activity contributes to AMPA-type glutamate receptor (AMPAR) membrane insertion, but until now, there was no clear understanding how this regulation could happen. We have identified the motif of ERK inhibiting PDE4 and controlling PKA output as a key step in the dopamine-induced membrane trafficking of GluA1. The significance of this regulatory motif is that it provides a point of integration for ERK activating signals to modulate neuronal excitability by tuning the trafficking of AMPAR.
Les Météores ou le Mythe Gémellaire revisité
Authors: Drouillard Jean-Raoul Austin de
Published: August 2013

The twins’ myth, whose origins go back to times immemorial, has always been a popular motif for fiction. It generally reflects the idea of “duality”, alienation and the search for Self and for the Other, which always end in an impasse. Self and for the Other, which always end in an impasse. With his novel Les Météores, portraying the twins Paul and Jean, Michel Tournier breaks away from this idea of “duality” and substitutes it with the idea of a “couple” through a mythic, metaphysical and symbolic approach whose outcome is sublimation. Initiation in a work of fiction by means of myths and symbols leads to something whose ethical dimension is realized by joining together difference and fraternity and by holding to the difference. It endeavours to carry out the transmutation of metaphysics in the work of fiction and the change from profane to sacred, from myth to the imaginary and to poetry.
Jean Baruzi y el problema del símbolo sanjuanista
Authors: Zafra Juan Varo
Published: August 2013

The article analyses and discusses the concepts of symbol and allegory in relation to Jean Baruzi’s classic study of the poetry of St. John of the Cross, Saint John of the Cross and the Problem of Mystical Experience. These concepts have been accepted to greater or lesser degree by the majority of St. John of the Cross criticism.

My reading attempts to trace the historical circumstances that conditioned Baruzi’s approach and argues for the need to reassess the reach and the pertinence of applying these aesthetic categories in the interpretation of 16th century mystical poetry, taking the conditions and unique specifics determined by the epoch and the parameters of the tradition of Christian mysticism as interpretive horizon.
O português popular europeu dos séculos XVI–XIX e a sua importância para o estudo do Galego Médio
Authors: Rei Xosé Manuel Sánchez
Published: August 2013

This article is centred around the linguistic information supplied by 16th and 18th century Portuguese grammar books, when, using as a basis the Lisbon variety, these works condemn the use of dialect or popular expressions habitually used. Like Galician, the language spoken in the territories lying to the North of the River Miño did not possess grammatical works until the 19th century, and so the information contained in these Portuguese grammars allows us to approach, with a reasonable degree of reliability, certain features of Middle Galician, a period in which the language, in Galicia, was only used at an oral level and was practically non-existent in any educated or written usage.

Pedro Páramo by Juan Rulfo is a multifaceted novel that incorporates Mexican cultural traits into literature and shapes the concept of Hispanic narration. The novel recreates the dramatic struggle for survival and its intriguing maneuvers. The main characters Pedro Páramo and Susan San Juan implement strategies that bring together realism and fantasy in their respective efforts to control the society and remain free. This essay is based on a specific work and tries to raise questions about humanity in general.
Cioran et le gouffre temporel
Authors: Barnett R.-L. Etienne
Published: August 2013

In the Cioranian universe, language and time, both inextricably bound, both chillingly perverse, constitute icons of what is, contextually, an inexorable vision of the human condition. The pairing progenerates specters, phantasms of the void, pernicious and vacuous. It is at the perilous, indeed, the perfidious nexus of enunciation and endlessness — each dreaded, yet each ineluctable — that the dyad adopts an onerous cast. To the extent that discourse configures a cipher of perpetuity, and in that, conversely, any trace of eternity conjures a ceaseless extension of the word, of that very word which begets and embodies postmodern aporia, there lurks in consequence of discourse emitted a palpable trepidation, a confrontation with the ultimate precipice, the unconscionable, inscrutable continuity of nothingness. The deconstructive imperative overtakes the text, from which there is neither scriptural nor metaphysical exit. A curious dynamic, a tangled skein of haunting refrain.
Amazonas del mar y sátiros acuáticos
Authors: Kluge Sofie
Published: August 2013

The work of Luis de Góngora (1561–1627) arguably represents the peak of early Baroque poetic mythography, but even if myth is a recurring element in Gongorine poetry its appearance varies greatly. From the youthful poetry to the major works of the first decades of the 17th century and beyond we find important nuances and a recurring revaluation and redefinition of myth. Thus, starting off by the both moral and sensual interpretation characteristic of Renaissance literature in the early sonnets, passing through Ovidian aetiology in the Fábula de Polifemo y Galatea and the philosophical meditation on myth in the Soledades, the poet reaches the satirical-burlesque with a moral flavour in the Fábula de Píramo y Tisbe. However, underlying all these different phases we find a persistent ambiguity rooted in the ambiguous post-classical reception of Greco-Roman mythology.

On the background of a brief survey of the ambiguous concept of classical mythology permeating Góngora’s work from beginning to end, the present article particularly explores the meditative phase of the Soledades, arguing its importance for our understanding of the Baroque period as well as for the origin of what may be termed the tradition of ’mythological literature’.

Mise en fiction des témoignages des convulsionnaires de Saint-Médard (1727–1732)
Authors: Kahan Michèle Bokobza
Published: August 2013

The cultural and religious phenomena of the convulsionaries of Saint-Médard, associated with the Parisian Jansenism, raises questions concerning the testimonial discourses and its procedures of validation and accreditation within the context of the Eighteenth Century in France. This essay explores the aesthetic and rhetoric strategies of the La Vérité des miracles, edited by Carré de Montgeron (1737). Its aim is to show how fictional procedures linked with poetics of horror and obscenity must be considerate as a part of a whole strategy of accessibility and popularization of the testimonial religious discourse. It highlights the complexity of the links between processes of writing testimony discourses and cultural changes concerning genders, sexuality, science and knowledge within the French society of this time.
Approche procédurale et référence temporelle du futur de l’indicatif en français
Authors: Castro Camino Álvarez
Published: August 2013

This essay analyses the future tense in the French verbal system in order to explore its semantic content, as well as its contribution to the fixation of temporal reference. Our study adopts a procedural perspective: we argue that the future tense has an instructional content that leads the hearer to a temporal — or other- interpretation of a given occurrence. We also contend that the semantics of the future tense is underdetermined and, thus, it must be filled by the hearer with co(n)textual information during the pragmatic process of interpretation. The analysis of the procedural meaning coded in the future tense — around three temporal coordinates — and its function in various linguistic environments prompts us to deal with temporality and aspectuality. Besides, it leads us to distinguish, among other things, a default instruction that we perceive as the trigger of a deictic calculation of the future temporal reference.
L’un dans l’autre
Authors: Gréa Philippe
Published: August 2013

L’un dans l’autre (“The one in the other”) is the name of a surrealist collective game created in the fifties by André Breton. Less famous than the exquisite cadavers, it is based on a particular use of the threaded metaphor and consists in an enigma that has to be cracked by the players. On the basis of Rastier 1987’s interpretive semantics, this study describes the semantic foundations of the game and the mechanisms that lead to the discovery of the solution. It shows how l’un dans l’autre forms what can be called a semic complex and how a rule of optimality eventually paves the way towards the answer.
Un autor fuera de lugar
Authors: de Armas Frederick
Published: August 2013

This essay deals with the imitation and mutations of the epic genre in Don Quijote. After discussing Cervantes’ literary career as an imitation of Virgil’s cursus, many of the Virgilian elements in the novel are foregrounded. These, however are transformed as they are come in contact with forms and notions derived from Lucan’s Pharsalia. While the knight believes in the ideals of the Virgilian epic, the narrators betray him, presenting a fragmented narrative, mutilated bodies, a de-centered world, a labyrinthine topography and the failures of the protagonist, thus creating a narrative of the defeated. The clash between the unitary, authoritative, and imperial Virgil with the fragmented and republican Lucan serves to create something novel in Cervantes, a new genre that will eventually be called the novel.
Un autre genre d’antimémoires
Authors: Boisen Jørn
Published: August 2013

One of the main characteristics of Romain Gary is the constant attempt to transgress the boundaries between life and fiction. His autobiographic texts are as a rule highly fictitious. On the other hand, in real life, he tried to live out a fiction written for him by his mother and, later on, by himself. The ambivalence of the relation between fiction and truth characterizes all of his books, but it is particularly interesting in his attempts at the autobiographical genre where it reveals a quite original understanding of human identity, and the dialectics of memory and forgetting,
El aforismo, género y concepto
Authors: Zafra Juan Varo
Published: August 2013

The peak of aphorisms leads us to set out questions regarding this form of expression which is a sort of mixture: half philosophy and half literature. Firstly, this paper examines the aphorism in terms of its complex definition: the maxim, the dictum, the apothegm, the enigma and the fragment. Secondly, this article brings out the differences between the aphorism and other forms, such as ‘greguería’, joke and riddle. Thirdly, this paper also studies the aphorism as a genre in its history. It questions and debates the relationship between the short classic literary forms and the modern aphorism. Finally, the diachronic analysis of the aphorism and the terminological analysis lead to a conception of this form that is linked to the human facticity, based on the intersection between world and language.
La historia de la partícula aparte en español
Authors: Sierra M.ª Elena Azofra
Published: August 2013

This paper deals with the history of the Spanish particle aparte. We describe this evolution from an adverbial usage (with spatial and modal values) to its current function as an additive discourse marker, taking into account its special character, which distinguishes aparte from the rest of the elements included in the subsystem of additive adverbs. As we show, the evolution of aparte is a typical instance of a subjectification process. Certain questions arise as to its adscription to a given syntactic category in certain contexts and about its lexicographic description in the Nuevo Diccionario Histórico.
Jeux transgressifs
Authors: Barnett R.-L. Etienne
Published: August 2013

In the textualized universe of Denis Roche, the poetic impulse is inextricably linked to the unstable framework in which such matter is cast. Utterances of language translate the power of transgression.The text is birthed as an object of inquiry, ultimately to be dismantled : the poem is both “inadmissible” and “inexistant.” As a self-fixed interrogator focused upon the residual matter that it is and which it only can be, it is no longer subservient to the references it struggles to invoke, much less to signify. Writing, then, is an unending auto-reflexive process of annihilation and reification, and subsists, as such, to the sole extent that it disassociates from all conventional voices of articulation. More obtusely, to poeticize is to re-transcribe — otherly and with abruptness — the withered sputtering(s) of the artistic imperative. Poetry, like photography, aims and frames, slices the world into sequences and images — partial, scattered, at once undone so as to be resuscitated, briefly, again. The extant is eschewed. At stake and at center-stage : a propelled form of motivity, speed, accelerations and dead-stops, an aleatory array of unremitting shifts, “instantanées” — obstinately un-emblematic. Raging or controlled, the poem or the photo can only be a non-representational sliver, the transitory residue of an infinite combinatorics of possibles. Hence, arbitrary breaches, clamoring interruptions, ludic contortions of incompleteness. A curious dynamic.
Une analyse en miroir de deux semi-copules évidentielles : s’avérer et se révéler
Authors: Tobback Els , Lauwers Peter
Published: August 2013

This paper offers a corpus-based study of two evidential (semi-)copular verbs in French. It deals with their degree of synonymy and the extent to which they are grammaticalized as semi-copulas. First, the study of subcategorization and semantic restrictions of both the direct and indirect (marked) construction with comme, completed by the careful scrutiny of contextual elements, shows that both verbs exhibit slight meaning differences with respect to the inferential process involved in the encoding of indirect inferential evidentiality (Willet 1988) : “results” (se révéler) vs “reasoning” (s’avérer). Second, both verbs fit quite well in the paradigm of copular verbs, although s’avérer seems slightly more ‘transparent’, that means less selective. Crucially, the uses of se révéler with nominal predicates quite often exhibit lexical persistence, while in the adjectival domain both verbs are almost twins as shown by a distinctive collexeme analysis.
Elena Martín Vivaldi
Authors: Rosal María
Published: August 2013

The object of this essay is to analyze a basic part of the work of the Spanish, Granada-born poet, Elena Martín Vivaldi, as well as her opinions and arguments about children’s literature. We start with the idea in the poetic work of Martín Vivaldi that there are some poems that stand out and could be aimed towards a children´s audience because of their subject matter, intention, and even their genesis. In this sense we want to reflect on the real possibilities that the work of this Spanish poet can connect with readers of different ages, and we suggest a corpus close to the taste of the youngest readers.
Linguistique de l’événement mescalinien chez Henri Michaux
Authors: Legallois Dominique
Published: August 2013

Misérable Miracle by Henri Michaux, is not only a poetic account of mescalinian experiments : in our opinion, the book also gives rise to a semiotic thinking on the notion of event. The paper is devoted to a detailed investigation of the manner in which 1) words — thanks to their iconic property — are events, 2) sentences are formed by the structure of events, and 3) texts — thanks to the rhetoric of energeia and enargeia — are designed as events by the reading horizon.

The intermediary phase of its phonetic evolution (cl’iuœu) is indirectly attested by the Ukr. klyva. The same Latin lexical base was preserved in Alb. qye as well. The Romanian word must be added to both the Romanian-Albanian correspondences registered up to the present day and to those among Romanian, Rhaeto-Romance and the Northern Italian dialects.

With reference to Paul Ricoeur’s essays Time and Narrative I–III (1983–1985) and Oneself as Another (1990), this paper discusses the Jewish element in some of the works of Marguerite Duras, especially in AbahnSabana David (1970). Using some of Ricoeur’s concepts such as sameness (idem) and selfhood (ipse) together with his model of a triple mimesis, the author argues that Duras’ strong engagement for justice for minority groups and especially for the Jewish cause, has its roots in thepréfiguration influenced by her upbringing in a French colony and by experiences in her close family during and after World War II. Her various uses of narrative silences characterize her style of writing, together with a deliberate confusion of identity marks in the presentation of her fictional characters.
Anaphore associative et anaphore possessive
Authors: Salles Mathilde
Published: August 2013

This paper is devoted to associative anaphora and possessive anaphora with two kinds of nouns. One is meronyms, where a noun denotes a concept that is a part of another as in trunk/tree. The other is what I call “functionally localized” nouns, such as church with respect to village, where the latter denotes a concept that normally implies the existence of the concept denoted by the former : see Kleiber (2001). We first evoke the referential properties of these two kinds of anaphora. The properties of the possessive determiner are then discussed in order to explain its occasional incompatibility with meronyms or functionally localized nouns. Finally, we elucidate the consequences for the choice between associative and possessive anaphora upon textual coherence relations, in particular Claim-Evidence (Cornish, 2009a, b) and Explanation.
The physical chemistry of cytoplasm and its influence on cell function: an update
Authors: Luby-Phelps Kate
Published: August 2013

From the point of view of intermolecular interactions, the cytoplasmic space is more like a crowded party in a house full of furniture than a game of tag in an empty field. Understanding the physical chemical properties of cytoplasm is thus of key importance for understanding cellular function. This article attempts to provide an entrée into the current literature on this subject and offers some general guidelines for thinking about intracellular biochemistry.

The Xin actin-binding repeat–containing proteins Xin and XIRP2 are exclusively expressed in striated muscle cells, where they are believed to play an important role in development. In adult muscle, both proteins are concentrated at attachment sites of myofibrils to the membrane. In contrast, during development they are localized to immature myofibrils together with their binding partner, filamin C, indicating an involvement of both proteins in myofibril assembly. We identify the SH3 domains of nebulin and nebulette as novel ligands of proline-rich regions of Xin and XIRP2. Precise binding motifs are mapped and shown to bind both SH3 domains with micromolar affinity. Cocrystallization of the nebulette SH3 domain with the interacting XIRP2 peptide PPPTLPKPKLPKH reveals selective interactions that conform to class II SH3 domain–binding peptides. Bimolecular fluorescence complementation experiments in cultured muscle cells indicate a temporally restricted interaction of Xin-repeat proteins with nebulin/nebulette during early stages of myofibril development that is lost upon further maturation. In mature myofibrils, this interaction is limited to longitudinally oriented structures associated with myofibril development and remodeling. These data provide new insights into the role of Xin actin-binding repeat–containing proteins (together with their interaction partners) in myofibril assembly and after muscle damage.

Recent discoveries of highly dispersed millisecond radio bursts by Thornton et al. in a survey with the Parkes radio telescope at 1.4 GHz point towards an emerging population of sources at cosmological distances whose origin is currently unclear. Here, we demonstrate that the scattering effects at lower radio frequencies are less than previously thought, and that the bursts could be detectable at redshifts out to about z = 0.5 in surveys below 1 GHz. Using a source model in which the bursts are standard candles with bolometric luminosities ∼8 × 1044 ergs s−1 uniformly distributed per unit comoving volume, we derive an expression for the observed peak flux density as a function of redshift and use this, together with the rate estimates found by Thornton et al. to find an empirical relationship between event rate and redshift probed by a given survey. The non-detection of any such events in Arecibo 1.4 GHz survey data by Deneva et al., and the Allen Telescope Array survey by Siemion et al. is consistent with our model. Ongoing surveys in the 1–2 GHz band should result in further discoveries. At lower frequencies, assuming a typical radio spectral index α = −1.4, the predicted peak flux densities are 10 s of Jy. As a result, surveys of such a population with current facilities would not necessarily be sensitivity limited and could be carried out with small arrays to maximize the sky coverage. We predict that sources may already be present in 350 MHz surveys with the Green Bank Telescope. Surveys at 150 MHz with 30 deg2 fields of view could detect one source per hour above 30 Jy.

Enzymatic synthesis and hydrolysis of nucleoside phosphate compounds play a key role in various biological pathways, like signal transduction, DNA synthesis and metabolism. Although these processes have been studied extensively, numerous key issues regarding the chemical pathway and atomic movements remain open for many enzymatic reactions. Here, using the Mason–Pfizer monkey retrovirus dUTPase, we study the dUTPase-catalyzed hydrolysis of dUTP, an incorrect DNA building block, to elaborate the mechanistic details at high resolution. Combining mass spectrometry analysis of the dUTPase-catalyzed reaction carried out in and quantum mechanics/molecular mechanics (QM/MM) simulation, we show that the nucleophilic attack occurs at the α-phosphate site. Phosphorus-31 NMR spectroscopy (31P-NMR) analysis confirms the site of attack and shows the capability of dUTPase to cleave the dUTP analogue α,β-imido-dUTP, containing the imido linkage usually regarded to be non-hydrolyzable. We present numerous X-ray crystal structures of distinct dUTPase and nucleoside phosphate complexes, which report on the progress of the chemical reaction along the reaction coordinate. The presently used combination of diverse structural methods reveals details of the nucleophilic attack and identifies a novel enzyme–product complex structure.
Influence of a component of solar irradiance on radon signals at 1 km depth, Gran Sasso, Italy

Published: August 2013

Exploratory monitoring of radon is conducted at one location in the deep underground Gran Sasso National Laboratory (LNGS). Measurements (15-min resolution) are performed over a time span of
ca
600 days in the air of the surrounding calcareous country rock. Using both
α
- and
γ
-ray detectors, systematic and recurring radon signals are recorded. Two primary signal types are determined: (i) non-periodic multi-day (MD) signals lasting 2–10 days and (ii) daily radon (DR) signals—which are of a periodic nature exhibiting a primary 24-h cycle (
θ
=0.48). The local ancillary environmental conditions (pressure, temperature) seem not to affect radon in air monitored at the site. Long-term patterns of daytime measurements are different from the pattern of night-time measurements indicating a day–night modulation of
γ
-radiation from radon in air. The phenomenology of the MD and DR signals is similar to situations encountered at other locations where radon is monitored with a high time resolution in geogas at upper crustal levels. In accordance with recent field and experimental results, it is suggested that a component of solar irradiance is affecting the radiation from radon in air, and this influence is further modulated by the diurnal rotation of the Earth. The occurrence of these radon signals in the 1 km deep low-radiation underground geological environment of LNGS provides new information on the time variation of the local radiation environment. The observations and results place the LNGS facility as a high-priority location for performing advanced investigations of these geophysical phenomena.
The effects of non-Newtonian rheology in the dynamic coefficients of wide slider bearings with a secant-shaped film profile

Published: August 2013

Purpose

– The purpose of this paper is to investigate the effects of non-Newtonian rheology on the dynamic characteristics of a secant-shaped couple-stress lubricated slider bearing.

Design/methodology/approach

– By applying the linear dynamic theory to the film force equation, a closed-form solution of the stiffness and damping coefficients is obtained for the secant-shaped bearing taking into account the non-Newtonian effects of Stokes couple stress fluids.

Findings

– Comparing with the secant-shaped Newtonian-lubricant bearing, the effects of non-Newtonian couple stresses provide an apparent improvement in the dynamic stiffness and damping characteristics, especially for the secant-shaped slider bearing operating at lower squeezing-film heights and with larger non-Newtonian couple stress parameters.

Originality/value

– Comparing with those of the inclined plane-shaped non-Newtonian slider bearings, better dynamic stiffness and damping performances are provided for the secant-shaped non-Newtonian slider bearing designed at larger values of the shoulder parameters. The advantages of secant-shaped slider-bearing types provide engineers useful information in bearing selection and engineering application.
