description: The electron - positron linear collider TESLA will require two Damping Rings, where the 2820 bunches, with an energy of 5 GeV, will be compressed to obtain a bunch spacing of 20ns. This bunch spacing fixes a Damping Ring length of 17 km. The major part of the damping ring will be installed in the linac tunnel; short return arcs, with a length of about 1.3 km each,will be installed in dedicated tunnels.This report describes the technical layout of one damping ring, developed in collaborationwith Ansaldo Ricerche, in all its components: magnetic system (dipoles, quadrupoles,sextupoles, steerers, electromagnetic wigglers), RF system (cryo-modules, RF power sources),Vacuum system (vacuum chambers, pumps, valves), Beam diagnostics, Computer control system, Electrical services, Cooling system, etc. Drawings showing the detailed ring layout and also every component of the ring are included.
The Deutschland83 miniseries. Technological representation of the Cold War between Ostalgie, vintage mood and Vergangenheitsbewältigung
Creators: name: Di Tonno, Francesca
Publisher: name: Series - International Journal of TV Serial Narratives
Year: 2020

description: The article analyzes the German television series Deutschland83 on air, not only in Germany, since 2015. The author wants to demonstrate how the use of representation in the eight episodes of the series of numerous technological objects from the Cold War period represents a way to tell in Germany's recent past before reunification to a new generation audience. From a methodological point of view, the article leans on semiotic and cultural studies themes, analyzing for each episode which type of technological object is highlighted by the plot and why. In the article neither the historical reconstruction nor the summary of the eight episodes of the series are left out. The vintage technological objects present in the Deutschland83 series can be divided into objects of common use and objects not of common use: in the first case, the objects have the task of historically contextualizing the series, in the second case, the objects not of common use they have the task of influencing the whole plot centered on the espionage activities of the protagonist Martin / Mortiz and his attempt to thwart nuclear war.

description: Over the last decade observations at submillimetre (submm) and millimetre (mm) wavelengths, with their unique ability to trace molecular gas and dust, have attained a central role in our exploration of galaxies at all redshifts. Due to the limited sensitivities and angular resolutions of current submm/mm telescopes, however, only the most luminous objects have been uncovered at high redshifts, with interferometric follow-up observations succeeding in resolving the dust and gas reservoirs in only a handful of cases. The coming years will witness a drastic improvement in the current situation, thanks to the arrival of a new suite of powerful submm observatories (single-dish and interferometers) with an order of magnitude improvement in sensitivity and resolution. In this overview I outline a few of what I expect to be the major advances in the field of galaxy formation and evolution that these new ground-breaking facilities will facilitate.

Against interactivity. Phenomenological notes on Black Mirror: Bandersnatch

Publisher: name: Series - International Journal of TV Serial Narratives
Year: 2020

description: Interactive cinema is one of the most interesting areas of experimentation with storytelling form. Black Mirror: Bandersnatch (2018), a stand-alone episode of the acclaimed British television series available on Netflix, has restarted the debate around this genre. This article offers a discussion of several critical elements inherent to the experience of viewing Bandersnatch, specifically those related to its interactive, meta-reflexive, and ludic character. The tension between interactive and interpretative cooperation, between actuality and virtuality, between self-reflexivity and self-referentiality, between free choice and control, between co-authorship and authority, and between gaming and gambling, bring out the contradictions of a product characteristic of the current transmedial landscape.

description: Unveiling the microscopic origins of quantum phases dominated by the interplay of spin and motional degrees of freedom constitutes one of the central challenges in strongly correlated many-body physics. When holes move through an antiferromagnetic spin background, they displace the positions of spins, which induces effective frustration in the magnetic environment. However, a concrete characterization of this effect in a quantum many-body system is still an unsolved problem. Here we present a Hamiltonian reconstruction scheme that allows for a precise quantification of hole-motion-induced frustration. We access non-local correlation functions through projective measurements of the many-body state, from which effective spin-Hamiltonians can be recovered after detaching the magnetic background from dominant charge fluctuations. The scheme is applied to systems of mixed dimensionality, where holes are restricted to move in one dimension, but SU(2) superexchange is two-dimensional. We demonstrate that hole motion drives the spin background into a highly frustrated regime, which can quantitatively be described by an effective J1–J2-type spin model. We exemplify the applicability of the reconstruction scheme to ultracold atom experiments by recovering effective spin-Hamiltonians of experimentally obtained 1D Fermi-Hubbard snapshots. Our method can be generalized to fully 2D systems, enabling promising microscopic perspectives on the doped Hubbard model.

description: The interaction of (linearized) gravitation with matter is studied in the causal approach up to the second order of perturbation theory. We consider the generic case and prove that gravitation is universal in the sense that the existence of the interaction with gravitation does not put new constraints on the Lagrangian for lower spin fields. We use the formalism of quantum off-shell fields which makes our computation more straightforward and simpler.

Putting the serial in context: Comparing the storytelling processes of contemporary primetime Kuwaiti television dramas with American network dramas
Creators: name: Hayat, Ahmad
Publisher: name: Series - International Journal of TV Serial Narratives
Year: 2020

description: Strictly designed with distinct narrative characteristics to accommodate the thirty day schedule of the holy month of Ramadan, Kuwaiti television dramas broadcast in a proliferated television landscape confined by the Arabic language and consists of television institutions operating from various Arab countries that compete for the vast pan-Arab audience. These unique broadcasting conditions inform the programme-making practices that shape the construction of narratives across the pan-Arab region. Like American network dramas, Kuwaiti dramas depend on advertising and syndication to generate revenue but the pan-Arab region’s technological adaptation transformed the production conditions and the commissioning processes of these dramas. By comparing the commissioning process of Kuwaiti television dramas with American network dramas, this article examines the development of the storytelling practices involved in shaping their narrative conventions and illuminates the manifestation of their industrial specificities in their narrative designs. The analyses of primary interviews with writers and representative dramas suggest that the unique shared broadcasting conditions of the pan-Arab region, accompanied by the particular operations of a television industry within the region, contribute to the commissioning process and designs of television dramas, and the challenges of this competitive language-confined environment underpins the prominent and intense implementation of serialized elements in Kuwaiti television dramas.

Victim-naming in the murder mystery TV series Twin Peaks: a corpus-stylistic study
Creators: name: Gregori Signes, Carmen
Publisher: name: Series - International Journal of TV Serial Narratives
Year: 2020

description: Corpus linguistics is advancing rapidly in the study of a wide variety of genres, but is still at its infancy in the study of TV series, a genre daily consumed by millions of viewers. Murder mystery series are one of the most popular and proliferous, but no studies, to date, have used corpus-stylistics methodologies in the analysis of the pivotal character of the victim in the whole narrative. This paper applied this methodology hoping to shed some light on the quantitative and qualitative relationship between the participation roles of the characters, and the frequency and distribution of victim-naming choices in the dialogue of the two first seasons of the acclaimed TV series Twin Peaks. The analysis proved that textual reference to the victim in the dialogues is a central genre-cohesive device which may serve as a waymark to guide the audience throughout the many subplots of the series.

IRAS-based whole-sky upper limit on Dyson Spheres
Creators: name: Carrigan, Richard A.
Publisher: name: arXiv
Year: 2008
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: A Dyson Sphere is a hypothetical construct of a star purposely cloaked by a thick swarm of broken-up planetary material to better utilize all of the stellar energy. A clean Dyson Sphere identification would give a significant signature for intelligence at work. A search for Dyson Spheres has been carried out using the 250,000 source database of the IRAS infrared satellite which covered 96% of the sky. The search has used the Calgary database for the IRAS Low Resolution Spectrometer (LRS) to look for fits to blackbody spectra. Searches have been conducted for both pure (fully cloaked) and partial Dyson Spheres in the blackbody temperature region 100 < T < 600 K. When other stellar signatures that resemble a Dyson Sphere are used to eliminate sources that mimic Dyson Spheres very few candidates remain and even these are ambiguous. Upper limits are presented for both pure and partial Dyson Spheres. The sensitivity of the LRS was enough to find Dyson Spheres with the luminosity of the sun out to 300 pc, a reach that encompasses a million solar- type stars.

description: We study the stochastic resonance (SR) of a flexible polymer surmounting a bistable-potential barrier. Due to the flexibility that can enhance crossing rate and change chain conformations at the barrier, the SR behaviors manifest many features of an entropic SR of a new kind, such as the power amplification peaks at optimal chain lengths and elastic constants as well as the optimal noise strengths. The pronounced peaks that emerge depending on the chain lengths and conformation states suggest novel means of manipulating biopolymers, such as efficient separation methods, within undulating channels.

description: In this poster contribution we highlight the equivalence between an Imaging Air Cherenkov Telescope (IACT) array and an Intensity Interferometer for a range of technical requirements. We touch on the differences between a Michelson and an Intensity Interferometer and give a brief overview of the current IACT arrays, their upgrades and next generation concepts (CTA, AGIS, completion 2015). The latter are foreseen to include 30-90 telescopes that will provide 400-4000 different baselines that range in length between 50m and a kilometre. Intensity interferometry with such arrays of telescopes attains 50 micro-arcseconds resolution for a limiting V magnitude of ~8.5. This technique opens the possibility of a wide range of studies, amongst others, probing the stellar surface activity and the dynamic AU scale circumstellar environment of stars in various crucial evolutionary stages. Here we discuss possibilities for using IACT arrays as optical Intensity Interferometers.

Faulkner's trilogy : technique as approach to theme
Creators: name: Galbraith, Margaret Edith
Publisher: name: University of British Columbia
Year: 2011

description: The purpose of this thesis is to show the relationship of technique to theme in Faulkner's Snopes Trilogy. The central theme, the continuous conflict in man between the world of nature and that of money, is revealed most clearly through certain structural and symbolic techniques. The conflict between the two ways of life is expressed structurally by a series of encounters; in the three novels, and symbolically by the tension between opposing symbols. The encounters usually take the form of a struggle between a man and a woman, the man representing the world of money, the woman, the world of nature. The most powerful symbols of nature, earth and season, are opposed by the most powerful symbols of the world of ownership, money, automobiles and monuments. The continuity of life is dramatized in the circular structure, which is seen in the apparently endless repetition of both the central conflict and the major symbols. In spite of certain limitations of the Trilogy, such as the fact that it must rely upon other books in the Yoknapatawpha cycle, and an unevenness which results from the great length of time in which It was written, it merits a more detailed study than has been accorded it by the majority of the critics in the past. A survey of the existing criticism indicates that it is inadequate largely because it fails to probe the novels deeply enough. Instead it often relies heavily on the traditional approach to Faulkner first suggested by George Marion O'Donnell, which says that all Faulkner's work is a variation of the theme of the struggle between Sartoris, the moral aristocrat, and Snopes, the amoral poor white. As a result of the influence of the traditional view, relatively few attempts have been made to approach the Trilogy in any other manner. The best approach to the meaning of the Trilogy is not through fixed interpretations but through technique. A detailed analysis of symbolic and structural technique in The Hamlet, The Town and The Mansion reveals the conflict and the continuity of life, and also the central focus of the novel. The focus in the Trilogy is not upon Flem Snopes but upon man. Man's struggle to reconcile the world of nature with that of money and ownership leads him to an understanding of the nature of evil within himself. The Trilogy stresses the fact that not only must man become morally aware of the evil within himself, but he must also struggle constantly to overcome it. Because he is a part of both worlds he must reconcile them as Ratliff does, not reject them as Stevens does. The reality of Faulkner's presentation of the conflict and continuity of man's life, as revealed by technique, makes the Trilogy a significant part of his work, worthy of a detailed study.

The intention was to bring together different approaches - in a community with a strong foundational background as proffered by the ICALP attendees - to create inspirational cross-boundary exchanges, and to lead to innovative further research. Specifically DCM 2009 sought contributions in quantum computation and information, probabilistic models, chemical, biological and bio-inspired ones, including spatial models, growth models and models of self-assembly. Contributions putting to the test logical or algorithmic aspects of computing (e.g., continuous computing with dynamical systems, or solid state computing models) were also very much welcomed.

description: By explicitly allowing for topology to change as a function of time, two-dimensional quantum gravity defined through causal dynamical triangulations gives rise to a new continuum string field theory. Within a matrix-model formulation we show that -- rather remarkably -- the associated sum over all genera can be performed in closed form, leading to a nonperturbative definition of CDT string field theory. We also obtain explicit formulas for the n-loop correlation functions. Our construction exhibits interesting parallels with previous, purely Euclidean treatments.

Imprinting, with special reference to anxiety
Creators: name: Dillon, Peter John
Publisher: name: University of British Columbia
Year: 2011

description: The general purpose of this research was to investigate the behaviour of newly-hatched chickens during their first few days of life. Various degrees of social isolation and of approximation to a normal environment were used, and special note was taken of their behaviour which might reflect the presence of anxiety in the chicks. With these observations as a base-line, the behaviour of comparable chicks in a typical imprinting situation was then examined, again with special reference to behavioural indices of anxiety. Based on both sets of observations, an analysis of the psychological processes underlying the behaviour in the imprinting situation was made. There were several reasons for proceeding in this manner: (1) Observation of chicks in a non-experimental situation provides knowledge of their usual behaviour, and thereby reduces the probability that subsequent interpretations will be artificial, and that subsequent conclusions regarding their behaviour will be erroneous. (2) Unless record is made of the usual behaviour of chicks in a non-experimental situation, it is not possible to assess the effect of any experimental procedure. (3) Reports in the literature have usually indicated that behaviour in the imprinting situation is characterized by fairly stereotyped following of a moving object. Preliminary observations and discussion suggested that such reports were entirely too narrow, and that other behaviour in the situation had been neglected. This other behaviour was felt to be as significant as the following behaviour customarily reported. Both sets of observation provided abundant evidence that the behaviour of the chicks in the imprinting situation was not fundamentally different from their behaviour in a less experimental environment, and confirmed the belief that the behaviour in the imprinting situation was not as rigid and narrow as usually reported. The several theories of imprinting were examined from this wider point of view, especially that of Howard Moltz (I960). Certain inconsistencies in Moltz’s theory were discussed, and some alternative ideas, mainly concerning anxiety novelty and habituation, were introduced.

description: In antiferromagnetically coupled multilayers with perpendicular anisotropy unusual multidomain textures can be stabilized due to a close competition between long-range demagnetization fields and short-range interlayer exchange coupling. In particular, the formation and evolution of specific topologically stable planar defects within the antiferromagnetic ground state, i.e. wall-like structures with a ferromagnetic configuration extended over a finite width, explain configurational hysteresis phenomena recently observed in [Co/Pt(Pd)]/Ru and [Co/Pt]/NiO multilayers. Within a phenomenological theory, we have analytically derived the equilibrium sizes of these "ferroband" defects as functions of the antiferromagnetic exchange, a bias magnetic field, and geometrical parameters of the multilayers. In the magnetic phase diagram, the existence region of the ferrobands mediates between the regions of patterns with sharp antiferromagnetic domain walls and regular arrays of ferromagnetic stripes. The theoretical results are supported by magnetic force microscopy images of the remanent states observed in [Co/Pt]/Ru.

Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: The first generation of stars was formed from primordial gas. Numerical simulations suggest that the first stars were predominantly very massive, with typical masses M > 100 Mo. These stars were responsible for the reionization of the universe, the initial enrichment of the intergalactic medium with heavy elements, and other cosmological consequences. In this work, we study the structure of Zero Age Main Sequence stars for a wide mass and metallicity range and the evolution of 100, 150, 200, 250 and 300 Mo galactic and pregalactic Pop III very massive stars without mass loss, with metallicity Z=10E-6 and 10E-9, respectively. Using a stellar evolution code, a system of 10 equations together with boundary conditions are solved simultaneously. For the change of chemical composition, which determines the evolution of a star, a diffusion treatment for convection and semiconvection is used. A set of 30 nuclear reactions are solved simultaneously with the stellar structure and evolution equations. Several results on the main sequence, and during the hydrogen and helium burning phases, are described. Low metallicity massive stars are hotter and more compact and luminous than their metal enriched counterparts. Due to their high temperatures, pregalactic stars activate sooner the triple alpha reaction self-producing their own heavy elements. Both galactic and pregalactic stars are radiation pressure dominated and evolve below the Eddington luminosity limit with short lifetimes. The physical characteristics of the first stars have an important influence in predictions of the ionizing photon yields from the first luminous objects; also they develop large convective cores with important helium core masses which are important for explosion calculations.

description: Current attempts to understand supersymmetry (susy) breaking are focused on the idea that we are not in the ground state of the universe but, instead, in a metastable state that will ultimately decay to an exactly susy ground state. It is interesting to ask how experiments at the Large Hadron Collider (LHC) will shed light on the properties of this future supersymmetric universe. In particular we ask how we can determine whether this final state has the possibility of supporting atoms and molecules in a susy background.

description: We have carried out long-term (14 years) V and R photometric monitoring of 12 carbon-rich proto-planetary nebulae. The light and color curves display variability in all of them. The light curves are complex and suggest multiple periods, changing periods, and/or changing amplitudes, which are attributed to pulsation. A dominant period has been determined for each and found to be in the range of ~150 d for the coolest (G8) to 35-40 d for the warmest (F3). A clear, linear inverse relationship has been found in the sample between the pulsation period and the effective temperature and also an inverse linear relationship between the amplitude of light variation and the effective temperature. These are consistent with the expectation for a pulsating post-AGB star evolving toward higher temperature at constant luminosity. The published spectral energy distributions and mid-infrared images show these objects to have cool (200 K), detached dust shells and published models imply that intensive mass loss ended a few thousand years ago. The detection of periods as long as 150 d in these requires a revision in the published post-AGB evolution models that couple the pulsation period to the mass loss rate and that assume that intensive mass loss ended when the pulsation period had decreased to 100 d. This revision will have the effect of extending the time scale for the early phases of post-AGB evolution. It appears that real time evolution in the pulsation periods of individual objects may be detectable on the time scale of two decades.

description: The market for electric vehicles (EVs) is growing rapidly. Subsidies and technological improvements are expected to increase the market share of EVs over the coming decade. In its base-case scenario, the International Energy Agency (IEA) expects EV use to rise from 4 million vehicles in 2018 to 120 million by 2030, or from 0.3 per cent to over 7 per cent of the global car fleet.

Kinematic Constraints to the Transition Redshift from SNe Ia Union Data

description: The kinematic approach to cosmological tests provides a direct evidence to the present accelerating stage of the universe which does not depend on the validity of general relativity, as well as on the matter-energy content of the Universe. In this context, we consider here a linear two-parameter expansion for the decelerating parameter, $q(z)=q_0+q_1z$, where $q_0$ and $q_1$ are arbitrary constants to be constrained by the Union supernovae data. By assuming a flat Universe we find that the best fit to the pair of free parameters is ($q_0,q_1$) = ($-0.73,1.5)$ whereas the transition redshift is $z_t = 0.49^{+0.14}_{-0.07}$ ($1σ$) $^{+0.54}_{-0.12}$ ($2σ$). This kinematic result is in agreement with some independent analyzes and accommodates more easily many dynamical flat models (like $Λ$CDM).

Stimulus-dependent correlations in threshold-crossing spiking neurons

description: We consider a threshold-crossing spiking process as a simple model for the activity within a population of neurons. Assuming that these neurons are driven by a common fluctuating input with Gaussian statistics, we evaluate the cross-correlation of spike trains in pairs of model neurons with different thresholds. This correlation function tends to be asymmetric in time, indicating a preference for the neuron with the lower threshold to fire before the one with the higher threshold, even if their inputs are identical. The relationship between these results and spike statistics in other models of neural activity are explored. In particular, we compare our model with an integrate-and-fire model in which the membrane voltage resets following each spike. The qualitative properties of spike cross correlations, emerging from the threshold-crossing model, are similar to those of bursting events in the integrate-and-fire model. This is particularly true for generalized integrate-and-fire models in which spikes tend to occur in bursts as observed, for example, in retinal ganglion cells driven by a rapidly fluctuating visual stimulus. The threshold crossing model thus provides a simple, analytically tractable description of event onsets in these neurons.

description: We present a necessary and sufficient condition for a 3 by 3 matrix to be unitarily equivalent to a symmetric matrix with complex entries, and an algorithm whereby an arbitrary 3 by 3 matrix can be tested. This test generalizes to a necessary and sufficient condition that applies to almost every n by n matrix. The test is constructive in that it explicitly exhibits the unitary equivalence to a complex symmetric matrix.

title: The Impact of a Trade War: Assessment of the Current Tariffs and Alternative Scenarios

description: This note uses Charbonneau and Landry’s (2018) framework to assess the direct impact of the current trade tensions on the Canadian and global economies, as well as possible implications if the conflict escalates further. Overall, my findings show that the estimated impact of current tariffs on real gross domestic product (GDP) remains relatively small, which is in line with the literature on gains from trade, but the impact on trade is much larger.

description: Dans la présente note, j’utilise le cadre d’analyse de Charbonneau et Landry (2018) pour évaluer l’incidence directe des tensions commerciales actuelles sur les économies canadienne et mondiale, ainsi que les répercussions possibles en cas d’escalade dans un conflit commercial. Dans l’ensemble, mes résultats indiquent que l’incidence estimative des droits de douane existants sur le produit intérieur brut (PIB) réel demeure relativement faible, ce qui concorde avec les résultats de la littérature sur les gains découlant des échanges commerciaux.
Editorial: Legumes and their microbiome in climate change mitigation
Creators: name: Monteoliva, Mariela I
Publisher: name: Zenodo
Year: 2023
Subjects: legumes, microbiome, climate change mitigation, sustainable agriculture, plant-microbe interactions

description: Climate change is intensifying abiotic and biotic stresses on agricultural and forestry systems. Legumes (Fabaceae), through their symbiotic relationships with microorganisms, play a key role in enhancing resilience and mitigating environmental impacts. This editorial introduces a Research Topic in Frontiers in Plant Science focused on the potential of legumes and their microbiomes in climate change mitigation. It includes four contributions—two original research articles and two reviews—covering breeding, intercropping, and microbial interactions. Topics addressed include the improvement of underutilized legumes like Bambara groundnut, the effect of soil water availability on intercropping systems, the yield impact of biological nitrogen fixation and phosphorus fertilization in West African legumes, and the biocontrol potential of Pseudomonas monteilii in forest ecosystems. The editorial emphasizes the need for integrated approaches that consider plant-microbiome-soil interactions to advance sustainable agriculture and ecosystem health.

description: The total cross-sections measured at LEP for e+e- annihilation into tau+tau-, c\bar{c} and b\bar{b} at 2E ~ 200 GeV are used to derive the upper limits 3*10^{-17}, 5*10^{-17}, 2*10^{-17} e*cm for the electric dipole moments and 4*10^{-17}, 7*10^{-17}, 2.5*10^{-17} e*cm for the weak dipole moments of the tau-lepton, c-, and b-quarks, respectively. Some of the existing limits on these moments are improved and for the b-quark the improvement is rather significant.

description: The adoption of inflation targeting (IT) by central banks leads to an increase of 10 to 20 percent in measures of financial development, with a lag. We also find evidence that the financial sector benefits of IT adoption were higher for early-adopting central banks.

description: L’adoption d’un régime de ciblage de l’inflation par les banques centrales entraîne une hausse de 10 à 20 % des mesures du développement des marchés financiers, avec un certain décalage. Nous constatons que les avantages pour le secteur financier ont été plus marqués dans les pays ayant adopté très tôt un tel régime.

Non-relativistic ab initio calculations for $2^2S$, $2^2P$ and $3^2D$ lithium isotopes: Applications to polarizabilities and dispersion interactions

description: The electric dipole polarizabilities and hyperpolarizabilities for the lithium isotopes $^6$Li and $^7$Li in the ground state $2^2S$ and the excited states $2^2P$ and $3^2D$, as well as the leading resonance and dispersion long-range coefficients for the Li($2^2S$)--Li($2^2S$) and Li($2^2S$)--Li($2^2P$) systems, are calculated nonrelativistically using variational wave functions in Hylleraas basis sets. Comparisons are made with published results, where available. We find that the value of the second hyperpolarizability of the $2^2S$ state is sensitive to the isotopic mass due to a near cancellation between two terms. For the $3^2D$ state polarizability tensor the calculated components disagree with those measured in the sole experiment and with those calculated semi-empirically.

description: We examine the velocity field of galaxies around the Virgo cluster induced by its overdensity. A sample of 1792 galaxies with distances from the Tip of the Red Giant Branch, the Cepheid luminosity, the SNIa luminosity, the surface brightness fluctuation method, and the Tully-Fisher relation has been used to study the velocity-distance relation in the Virgocentric coordinates. Attention was paid to some observational biases affected the Hubble flow around Virgo. We estimate the radius of the zero-velocity surface for the Virgo cluster to be within (5.0 - 7.5) Mpc corresponding to (17 - 26)^\circ at the mean cluster distance of 17.0 Mpc. In the case of spherical symmetry with cosmological parameter Ω_m=0.24 and the age of the Universe T_0= 13.7 Gyr, it yields the total mass of the Virgo cluster to be within M_T=(2.7 - 8.9) * 10^{14} M_\sun in reasonable agreement with the existing virial mass estimates for the cluster.

description: We study numerically the phase diagram and the response under a driving force of the phase field crystal model for pinned lattice systems introduced recently for both one and two dimensional systems. The model describes the lattice system as a continuous density field in the presence of a periodic pinning potential, allowing for both elastic and plastic deformations of the lattice. We first present results for phase diagrams of the model in the absence of a driving force. The nonlinear response to a driving force on an initially pinned commensurate phase is then studied via overdamped dynamic equations of motion for different values of mismatch and pinning strengths. For large pinning strength the driven depinning transitions are continuous, and the sliding velocity varies with the force from the threshold with power-law exponents in agreement with analytical predictions. Transverse depinning transitions in the moving state are also found in two dimensions. Surprisingly, for sufficiently weak pinning potential we find a discontinuous depinning transition with hysteresis even in one dimension under overdamped dynamics. We also characterize structural changes of the system in some detail close to the depinning transition.
