The acquisition of objects clitics in Italian: Data from an elicited production task
Creators: name: Tedeschi, Roberta

Year: 2012

description: L'acquisizione dei pronomi clitici, elemento centrale della ricerca in  ambito linguistico (Guasti [1993-1994], Schaeffer [2000], Wexler et al. [2004], Hamann et al. [1996], Jakubovicz et al. [1998] e molti altri), può essere studiata come un fenomeno  d'interfaccia: l'uso adulto di queste parole funzionali implica la  padronanza di diversi aspetti della conoscenza linguistica (Monachesi  [2007]). Studi recenti sull'Italiano indicano che i clitici sono fin da  subito posizionati in modo corretto (Guasti [1993-1994], Cipriani et al. [1993], Antelmi [1997], Schaeffer [2000]). Tuttavia, nei primi stadi  dello sviluppo linguistico, il numero dei clitici prodotti è basso, e il  loro uso è caratterizzato da omissioni opzionali. In questo articolo  vengono presentati i risultati di uno studio pilota mirato alla  produzione di clitici oggetto in bambini di età compresa tra i 3 e i 4  anni. I dati, riguardanti errori di accordo e omissioni, vengono  discussi dal punto di vista sintattico, semantico e pragmatico. Sulla  base di recenti studi sull'integrazione di sintassi e discorso nei primi  anni di vita (Schaeffer [2000], Serratrice [2004], Avrutin [2004]),  particolare attenzione viene posta sull'acquisizione del sistema  referenziale associato a nomi e  pronomi.

description: We consider the phenomenological implications of the assumption that baryons are systems of three quarks connected through gluon string junction. The transfer of baryon number in rapidity space due to the string junction propagation is considered in detail. At high energies this process leads to a significant effect on the net baryon production in hN collisions at mid-rapidities. The numerical results for midrapidity inclusive densities of different secondaries in the framework of the Quark-Gluon String Model are in reasonable agreement with the experimental data. One universal value lambda ~ 0.25 for the strangeness suppression parameter correctly describes the yield ratios of Lambda/p, Xi/Lambda, and Omega/Xi. The predictions for pp collisions at LHC energies are also presented.

description: We study the local symplectic algebra of parameterized curves introduced by V. I. Arnold. We use the method of algebraic restrictions to classify symplectic singularities of quasi-homogeneous curves. We prove that the space of algebraic restrictions of closed 2-forms to the germ of an analytic curve is a finite dimensional vector space. We also show that the action of local diffeomorphisms preserving the curve on this vector space is determined by the infinitesimal action of liftable vector fields. We apply these results to obtain the complete symplectic classification of curves with the semigroups (3,4,5), (3,5,7), (3,7,8).

Estudio crítico de Sefarad, Novela de Novelas

description: Con Sefarad: una novela de novelas Antonio Muñoz Molina è riuscito a inserire un'opera di fiction scritta in spagnolo nel dibattito intellettuale sull'Olocausto. Questo  testo, su cui è imperniato il nostro studio, testimonia la maturità  tecnica del suo autore. Ma siamo anche di fronte a un'opera che dialoga  continuamente con altri testi e con la sua stessa struttura. Perciò si è  deciso di realizzare un'analisi immanente della struttura dell'opera e  delle problematiche segnalate al suo interno. Il testo propone un  accostamento a una serie di individui, con referenti reali o meno, che  furono oppressi e perseguitati dai due grandi totalitarismi del  ventesimo secolo; ma offre anche un accostamento a una determinata  tradizione testuale. Il tema dell'esilio e della persecuzione ideologica  da parte del regime nazista e del comunismo stalinista è utilizzato  come nucleo tematico per abbinare a esso la propria esperienza di  sradicamento personale. Il fatto è che siamo dinanzi a un testo che  invita alla riflessione e al dibattito, ma che ha soprattutto la gran  virtù di invitarci ad altre letture. Un testo che non si chiude su se  stesso ma si innesta in una delle tradizioni letterarie del XX secolo  esemplificate con profondità e responsabilità dalle opere di Primo Levi o  Jean Améry.

A structure-preserving finite element method for compressible ideal and resistive MHD
Creators: name: Gawlik, Evan S.
name: Gay-Balmaz, François
Publisher: name: arXiv
Year: 2021
Subjects: subject: Numerical Analysis (math.NA)

description: We construct a structure-preserving finite element method and time-stepping scheme for compressible barotropic magnetohydrodynamics (MHD) both in the ideal and resistive cases, and in the presence of viscosity. The method is deduced from the geometric variational formulation of the equations. It preserves the balance laws governing the evolution of total energy and magnetic helicity, and preserves mass and the constraint $ \operatorname{div}B = 0$ to machine precision, both at the spatially and temporally discrete levels. In particular, conservation of energy and magnetic helicity hold at the discrete levels in the ideal case. It is observed that cross helicity is well conserved in our simulation in the ideal case.

description: In densely populated urban areas WiFi routers form a tightly interconnected proximity network that can be exploited as a substrate for the spreading of malware able to launch massive fraudulent attack and affect entire urban areas WiFi networks. In this paper we consider several scenarios for the deployment of malware that spreads solely over the wireless channel of major urban areas in the US. We develop an epidemiological model that takes into consideration prevalent security flaws on these routers. The spread of such a contagion is simulated on real-world data for geo-referenced wireless routers. We uncover a major weakness of WiFi networks in that most of the simulated scenarios show tens of thousands of routers infected in as little time as two weeks, with the majority of the infections occurring in the first 24 to 48 hours. We indicate possible containment and prevention measure to limit the eventual harm of such an attack.

A new Lagrange multiplier approach for constructing structure preserving schemes, I. positivity preserving

Publisher: name: arXiv
Year: 2021
Subjects: subject: Numerical Analysis (math.NA)

description: We propose a new Lagrange multiplier approach to construct positivity preserving schemes for parabolic type equations. The new approach introduces a space-time Lagrange multiplier to enforce the positivity with the Karush-Kuhn-Tucker (KKT) conditions. We then use a predictor-corrector approach to construct a class of positivity schemes: with a generic semi-implicit or implicit scheme as the prediction step, and the correction step, which enforces the positivity, can be implemented with negligible cost. We also present a modification which allows us to construct schemes which, in addition to positivity preserving, is also mass conserving. This new approach is not restricted to any particular spatial discretization and can be combined with various time discretization schemes. We establish stability results for our first- and second-order schemes under a general setting, and present ample numerical results to validate the new approach.
Asymptotic expansions for the escape rate of stochastically perturbed unimodal maps

Publisher: name: arXiv
Year: 2008
Subjects: subject: Chaotic Dynamics (nlin.CD)

description: The escape rate of a stochastic dynamical system can be found as an expansion in powers of the noise strength. In previous work the coefficients of such an expansion for a one-dimensional map were fitted to a general form containing a few parameters. These parameters were found to be related to the fractal structure of the repeller of the system. The parameter alpha, the "noise dimension", remains to be interpreted. This report presents new data for alpha showing that the relation to the dimensions is more complicated than predicted in earlier work and oscillates as a function of the map parameter, in contrast to other dimension-like quantities.

description: Spatially indirect excitons with displaced wavefunctions of electrons and holes play a pivotal role in a large portfolio of fascinating physical phenomena and emerging optoelectronic applications, such as valleytronics, exciton spin Hall effect, excitonic integrated circuit and high-temperature superfluidity. Here, we uncover three types of spatially indirect excitons (including their phonon replicas) and their quantum-confined Stark effects in hexagonal boron nitride encapsulated bilayer WSe2, by performing electric field-tunable photoluminescence measurements. Because of different out-of-plane electric dipole moments, the energy order between the three types of spatially indirect excitons can be switched by a vertical electric field. Remarkably, we demonstrate, assisted by first-principles calculations, that the observed spatially indirect excitons in bilayer WSe2 are also momentum-indirect, involving electrons and holes from Q and K/Γ valleys in the Brillouin zone, respectively. This is in contrast to the previously reported spatially indirect excitons with electrons and holes localized in the same valley. Furthermore, we find that the spatially indirect intervalley excitons in bilayer WSe2 can exhibit considerable, doping-sensitive circular polarization. The spatially indirect excitons with momentum-dark nature and highly tunable circular polarization open new avenues for exotic valley physics and technological innovations in photonics and optoelectronics.

description: Circumstellar disks are expected to form early in the process that leads to the formation of a young star, during the collapse of the dense molecular cloud core. It is currently not well understood at what stage of the collapse the disk is formed or how it subsequently evolves. We aim to identify whether an embedded Keplerian protoplanetary disk resides in the L1489 IRS system. Given the amount of envelope material still present, such a disk would respresent a very young example of a protoplanetary disk. Using the Submillimeter Array (SMA) we have observed the HCO$^+$ $J=$ 3--2 line with a resolution of about 1$''$. At this resolution a protoplanetary disk with a radius of a few hundred AUs should be detectable, if present. Radiative transfer tools are used to model the emission from both continuum and line data. We find that these data are consistent with theoretical models of a collapsing envelope and Keplerian circumstellar disk. Models reproducing both the SED and the interferometric continuum observations reveal that the disk is inclined by 40$^\circ$ which is significantly different to the surrounding envelope (74$^\circ$). This misalignment of the angular momentum axes may be caused by a gradient within the angular momentum in the parental cloud or if L1489 IRS is a binary system rather than just a single star. In the latter case, future observations looking for variability at sub-arcsecond scales may be able to constrain these dynamical variations directly. However, if stars form from turbulent cores, the accreting material will not have a constant angular momentum axis (although the average is well defined and conserved) in which case it is more likely to have a misalignment of the angular momentum axes of the disk and the envelope.

The effect of mode variation on syntactic complexity in adult E.S.L. composition writing
Creators: name: Sinclair, Victor Eugene
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to determine whether variation in mode of discourse would produce significant differences in syntactic complexity, as measured by mean number of words per T-unit, in compositions written by-adult- students of English as a second language. To answer this question, compositions were collected from eight classes of Advanced level students in the English Language Training Department at King Edward Campus in Vancouver. Each student in the study wrote eight compositions over an eight week period in the Fall of 1981. Two different topics were assigned in each of four modes with the topics assigned to class in random order. The compositions of those students who wrote on every topic at the appointed time (N=61) were divided into T-units, words were counted and words per T-unit calculated. The mean number of words per T-unit per mode was then determined for description, narration, argument, and exposition. Differences, in mean number of words per T-unit for six pairs of modes were tested for significance at the .05 level. The six pairs, narration-description, narration-exposition, narration-argument, description-exposition, description-argument, and exposition-argument were analyzed using a t-test for dependent measures. The results indicated that there were significant differences in W/TU between five of six pairs with no significant difference only for narration-description. The order of complexity indicated from these results was N=D< A< E. The order of complexity found in this study is similar to that found in other first and second language studies, in that argument and exposition were shown to produce greater syntactic complexity than either narration or description. Other results found in this study showed that a high proportion of students wrote "out of mode" when given tasks in argument and exposition whereas almost all subjects remained "in mode" when writing in description or narration. The results of this study showing syntactic complexity to be a function of mode of discourse suggests strongly that where complexity is a factor of consideration either in research or evaluation, mode must be controlled or results interpreted with the recognition of a potential mode effect.

description: The simplicity of the visual servoing approach makes it an attractive option for tasks dealing with vision-based control of robots in many real-world applications. However, attaining precise alignment for unseen environments pose a challenge to existing visual servoing approaches. While classical approaches assume a perfect world, the recent data-driven approaches face issues when generalizing to novel environments. In this paper, we aim to combine the best of both worlds. We present a deep model predictive visual servoing framework that can achieve precise alignment with optimal trajectories and can generalize to novel environments. Our framework consists of a deep network for optical flow predictions, which are used along with a predictive model to forecast future optical flow. For generating an optimal set of velocities we present a control network that can be trained on the fly without any supervision. Through extensive simulations on photo-realistic indoor settings of the popular Habitat framework, we show significant performance gain due to the proposed formulation vis-a-vis recent state-of-the-art methods. Specifically, we show a faster convergence and an improved performance in trajectory length over recent approaches.

description: Industrial plants suffer from a high degree of complexity and incompatibility in their communication infrastructure, caused by a wild mix of proprietary technologies. This prevents transformation towards Industry 4.0 and the Industrial Internet of Things. Open Platform Communications Unified Architecture (OPC UA) is a standardized protocol that addresses these problems with uniform and semantic communication across all levels of the hierarchy. However, its adoption in embedded field devices, such as sensors and actors, is still lacking due to prohibitive memory and power requirements of software implementations. We have developed a dedicated hardware engine that offloads processing of the OPC UA protocol and enables realization of compact and low-power field devices with OPC UA support. As part of a proof-of-concept embedded system we have implemented this engine in a 22 nm FDSOI technology. We measured performance, power consumption, and memory footprint of our test chip and compared it with a software implementation based on open62541 and a Raspberry Pi 2B. Our OPC UA hardware engine is 50 times more energy efficient and only requires 36 KiB of memory. The complete chip consumes only 24 mW under full load, making it suitable for low-power embedded applications.

description: This letter presents a closed-form integral-equation formulation that models the director tilting in nematic liquid crystals. The proposed formulation is computationally efficient compared to numerical methods and provides a physical insight on the matter. Our previous work is generalized from the one-constant approach to all the possible cases that cover the elastic constants. These constants determine in great extent the electrical properties of the liquid crystal, and subsequently, the response of the reconfigurable devices that take use of it. Therefore, a more precise but still simple modeling of their influence is pursued here. Simulations show good agreement with numerical implementations. In comparison, the error in the estimation is considerably reduced when using the integral-equation formulation, specially as the polarization voltage or the dielectric anisotropy decreases.

description: In this paper we study the question of how to transfer homotopic structure from the category sD of simplicial objects in a fixed category D to D. To this end we use a sort of homotopy colimit s : sD --> D, which we call simple functor. For instance, the Bousfield-Kan homotopy colimit in a Quillen simplicial model category is an example of simple functor. As a remarkable example outside the setting of Quillen models we include Deligne simple of mixed Hodge complexes. We prove here that the simple functor induces an equivalence on the corresponding localized categories. We also describe a natural structure of Brown category of cofibrant objects on sD. We use these facts to produce cofiber sequences on the localized category of D by E, which give rise to a natural Verdier triangulated structure in the stable case.

description: Using worldsheet Hamiltonian methods we derive a charge algebra which generalizes the Courant bracket to include fluxes of general index type. This is achieved by coupling a bi-vector to the Hamiltonian of the Polyakov model. This bracket is useful to describe so-called non-geometric backgrounds and has been discussed in the mathematics literature by Dmitry Roytenberg.

description: We have compared numerical simulations to observations for the nearby (< 40 Mpc) groups of galaxies (Huchra & Geller 1982 and Ramella et al. 2002). The group identification is carried out using a group-finding algorithm developed by Huchra and Geller (1982). Using cosmological N-body simulation code with the LambdaCDM cosmology, we show that the dynamical properties of groups of galaxies identified from the simulation data are, in general, in a moderate, within 2sigma, agreement with the observational catalogues of groups of galaxies. As simulations offer more dynamical information than observations, we used the N-body simulation data to calculate whether the nearby groups of galaxies are gravitationally bound objects by using their virial ratio. We show that in a LambdaCDM cosmology about 20 per cent of nearby groups of galaxies, identified by the same algorithm as in the case of observations, are not bound, but merely groups in a visual sense. This is quite significant, specifically because estimations of group masses in observations are often based on an assumption that groups of galaxies found by the friends-of-friends algorithm are gravitationally bound objects. Simulations with different resolutions show the same results. We also show how the fraction of gravitationally unbound groups varies when the apparent magnitude limit of the sample and the value of the cosmological constant is changed. In general, a larger value of the Omega_Lambda generates slightly more unbound groups.

description: 8. Stachys hakkariensis Akçiçek & Fırat, Phytotaxa 257: 168 (2016) (Figs. 1D, 6, 8)
Type:― TURKEY. C9 Hakkari: between Şine and Marinus (Çîyayêreş Mountain, Bemro region), rocky slopes, eroded slopes, 37 o 29’53”N 43 o 27’47”E, 1200 m, 7 July 2015, M. Fırat 32600 (holo: GAZI!; iso: ISTE!, Hb. Akçiçek!, Hb. M.Fırat!)
Description:―Suffrutescent perennial herbs, without basal rosettes of leaves. Flowering stems 40‒80cm tall, ascending, slender, very much branched, glabrous with sparsely sessile glands. Cauline leaves linear to linear-lanceolate, 0.7‒7 × 0.1‒0.3(‒0.5) cm, entire at margin, acute at apex, glabrous with sparsely sessile glands. Floral leaves similar to cauline leaves, but smaller, linear to linear-lanceolate gradually shorter than verticillasters above, 2‒12(‒15) mm, entire at margin, acute at apex. Verticillasters (2‒)3‒5, remote, (1.2‒) 1.5‒6 cm distant, (1‒)2(‒3)-flowered. Bracteoles few, minute, setaceous, 1‒2 mm, margin antrorsely hairy. Pedicels 1.5‒2 mm long. Calyx ± regular, subcampanulate, 5.5‒7.5 mm, glabrous, mouth scarsely hairy (between calyx teeth); teeth ± equal, triangular-lanceolate, 1.5‒2 mm long, ca. 1/3 of the tube, slightly recurved, shortly mucronate-tipped (mucron ca. 0.2 mm long). Corolla white, 10‒12 mm long; lips streaked and spotted with pink inside, densely short adpressed hairy outside; tube subexserted, annulate; limb bilabiate, upper lip ± 5 mm long, the lower 3-lobed, middle lobe longer than 2 lateral lobes, 4‒5 mm long, rounded. Stamens 4, slightly exserted from corolla tube. Nutlets obovoid, faintly trigonous, slightly winged near base, 2.5‒3 × 1.7‒2 mm. blackish-brown.
Phenology: ―Flowering and fruiting from July to October.
Distribution and ecology: ―Endemic to Turkey (Eastern Anatolia). Rocky slopes, eroded slopes. 1150‒1200 m elevation.
Conservation status: ―EN [Criteria B2ab(i,iii)] (IUCN 2017). This species is endemic to Hakkari Province in eastern Anatolia. It is only known from two locations at altitudes of 1150–1200 m, where the number of mature individuals is approximately 100. The habitat of this species is threatened by mineral extraction activities, soil erosion, and deforestation in the area.
Remarks: ― Stachys hakkariensis is closely related to S. sparsipilosa Bhattacharjee & Huber-Morath (1974: 287), but it differs mainly by its many branched stems, herbaceous bracts, verticillasters 3‒5 with (1‒)2(‒3) flower, shorter pedicels, calyx ± regular with teeth 1.5‒2 mm long with short mucrone, corolla white and nutlets obovoid.

description: The importance is emphasized of taking into account the channeling along the low index crystallographic axes and planes of a part of low-energy (1-10 keV) recoil ions in measurements of their parameters with crystal scintillators of the type of NaI(Tl) etc. Because the nucleus stopping power in channels is low as compared with electronic stopping power, the light yield of the scintillator must be, accordingly, higher in the given case than that for ions having higher energy (tens keV and more), which lose most part of their energy via nuclear collisions outside channels. Hence, in particular, it follows that the DAMA/NaI observations in Gran Sasso of the annual modulation of the signal frequency in a narrow range of scintillations with an amplitude of 2-6 keV electron equivalent may be due to incidence onto the Earth of exceedingly massive particles (of the type of Planckian objects) from elongated Earth-crossing heliocentric orbits at a velocity of 30-50 km/s. In NaI(Tl), these particles create the iodine recoil ions with just the energy of 2-6 keV.

description: Nearby massive compact elliptical galaxies (MCEGs) are strong candidates for relic galaxies (i.e. local analogs of red nuggets at high redshifts). It is expected that the globular cluster (GC) systems of relic galaxies are dominated by red (metal-rich) GCs. NGC 1277 is known as a unique example of such a galaxy in the previous study. In this study, we search for GCs in 12 nearby MCEGs at distances of $\lesssim 100$ Mpc from the Hubble Space Telescope/Wide Field Camera 3 F814W($I_{814}$)/F160W($H_{160}$) archival images. We find that most of these MCEGs host a rich population of GCs with a color range of $0.0

From SPS to RHIC: Maurice and the CERN heavy-ion programme
Creators: name: Heinz, Ulrich W.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: Maurice Jacob played a key role in bringing together different groups from the experimental and theoretical nuclear and particle physics communities to initiate an ultrarelativistic heavy-ion collision program at the CERN SPS, in order to search for the quark-gluon plasma. I review the history of this program from its beginnings to the time when the Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory (BNL) started operation. I close by providing a glimpse of the important discoveries made at RHIC and giving an outlook towards heavy-ion collisions at the Large Hadron Collider (LHC). During Maurice's life and not least through his perpetually strong influence, relativistic heavy-ion physics has matured and led to discoveries that radiate into many other fields of physics. Heavy-ion physicists owe a great deal to Maurice Jacob.

description: We show that if $X$ is an indecomposable $PD_3$-complex and $π_1(X) is the fundamental group of a reduced finite graph of finite groups but is not virtually cyclic then $X$ is orientable, the underlying graph is a tree, all the edge groups are $Z/2Z$ and all but at most one of the vertex groups is dihedral of order $2m$ with $m$ odd. Every such group is realized by some $PD_3$-complex. We also propose a strategy for tackling the question of whether every $PD_3$-complex has a finite covering space which is homotopy equivalent to a closed orientable 3-manifold.
description: 22 pages. The determination of the possible fundamental groups has been completed. A lemma has been added to Section 2, and the main theorem (5.2) has been strengthened

description: Coupled cluster Green's function (CCGF) approach has drawn much attention in recent years for targeting the molecular and material electronic structure problems from a many-body perspective in a systematically improvable way. Here, we will present a brief review of the history of how the Green's function method evolved with the wavefunction, early and recent development of CCGF theory, and more recently scalable CCGF software development. We will highlight some of the recent applications of CCGF approach and propose some potential applications that would emerge in the near future.
