description: Dual-unitary circuits have emerged as a minimal model for chaotic quantum many-body dynamics in which the dynamics of correlations and entanglement remains tractable. Simultaneously, there has been intense interest in the effect of measurements on the dynamics of quantum information in many-body systems. In this work we introduce a class of models combining dual-unitary circuits with particular projective measurements that allow the exact computation of dynamical correlations of local observables, entanglement growth, and steady-state entanglement. We identify a symmetry preventing a measurement-induced phase transition and present exact results for the intermediate critical purification phase.

description: L’area del Mediterraneo è estremamente vulnerabile ai cambiamenti climatici con importanti variazioni che negli ultimi anni hanno interessato sia le temperature che le precipitazioni. Per quanto riguarda il regime pluviometrico, nonostante l’eterogeneità spaziale, complessivamente prevale un aumento dei giorni siccitosi con piogge che tendono a concentrarsi in meno giorni e un conseguente aumento dei fenomeni intensi. Negli ultimi anni l’azione 733 del COST ha messo a disposizione un importante strumento per semplificare la complessità climatica in un numero limitato di tipi di circolazione, tale da consentire anche una lettura locale dell’impatto del Global Warming. In questo studio l’attenzione viene focalizzata sul trend delle precipitazioni intense (R90p, ovvero il numero di giorni con quantitativi di precipitazioni superiori al 90° percentile della distribuzione climatologica) per 46 stazioni meteorologiche distribuite a varie quote sull’intero territorio nazionale italiano, tra gennaio 1979 e dicembre 2015. E’ stata inoltre indagata, sia a livello annuale che stagionale, la relazione delle precipitazioni intense con una classificazione di tipi di circolazione atmosferica derivata da un precedente studio come quella più idonea a stratificare le precipitazioni sull’Italia. Tale classificazione consta di 9 classi ed è stata ottenuta attraverso il metodo di “clustering” Principal Component Transversal (PCT09). L’indagine si basa essenzialmente sul calcolo di due indici per ognuna delle stazioni considerate: (i) indice EF (Effectiveness) che descrive la predisposizione di ciascun tipo di circolazione a produrre precipitazioni intense in una data località e (ii) l’indice EXPOT (EXtreme POTential), che descrive la frequenza di precipitazioni intense in ogni tipo di circolazione. L’indice EXPOT in particolare è stato utilizzato anche per evidenziare eventuali trend legati a fattori climatici che agiscono su scala decadale o multi-decadale. Lo studio ha evidenziato una buona predisposizione della classificazione utilizzata per stratificare le precipitazioni intense e alcuni trend significativi dell’indice EXPOT.

Overview

Ces cent cinquante contes soufis sont tirés du Mesnevi, oeuvre essentielle de Rûmî, fondateur de l'ordre des derviches tourneurs, poète, mystique et sage du Xllle siècle. Considéré comme un commentaire du Coran, le Mesnevi ne fut pas seulement étudié dans le cadre des confréries, mais aussi dans les mosquées. Des commentaires et des traductions du persan virent le jour et le Mesnevi devint l'une des sources reconnues de l'enseignements traditionnel. Versets du Coran, Hadiths, légendes bibliques, contes hindous ou bouddhistes, péripéties de la vie quotidienne provoquent l'inspiration de Rûmî et illustrent l'enseignement soufi, à la fois tradition vivante, simple et accessible par tous, et sagesse universelle.

description: Type Ia supernovae (SN Ia) are the most important standard candles for measuring the expansion history of the universe. The thermonuclear explosion of a white dwarf can explain their observed properties, but neither the progenitor systems nor any stellar remnants have been conclusively identified. Underluminous SN Ia have been proposed to originate from a so-called double-detonation of a white dwarf. After a critical amount of helium is deposited on the surface through accretion from a close companion, the helium is ignited causing a detonation wave that triggers the explosion of the white dwarf itself. We have discovered both shallow transits and eclipses in the tight binary system CD-30 11223 composed of a carbon/oxygen white dwarf and a hot helium star, allowing us to determine its component masses and fundamental parameters. In the future the system will transfer mass from the helium star to the white dwarf. Modelling this process we find that the detonation in the accreted helium layer is sufficiently strong to trigger the explosion of the core. The helium star will then be ejected at so large a velocity that it will escape the Galaxy. The predicted properties of this remnant are an excellent match to the so-called hypervelocity star US 708, a hot, helium-rich star moving at more than 750 km/s, sufficient to leave the Galaxy. The identification of both progenitor and remnant provides a consistent picture of the formation and evolution of underluminous type Ia supernovae.

description: In wetland ecosystems, birds and fish are important dispersal vectors for plants and invertebrates, but the consequences of their interactions as vectors are unknown. Darwin suggested that piscivorous birds carry out secondary dispersal of seeds and invertebrates via predation on fish. We tested this hypothesis in the great cormorant (Phalacrocorax carbo L.). Cormorants regurgitate pellets daily, which we collected at seven European locations and examined for intact propagules. One-third of pellets contained at least one intact plant seed, with seeds from 16 families covering a broad range of freshwater, marine and terrestrial habitats. Of 21 plant species, only two have an endozoochory dispersal syndrome, compared to five for water and eight for unassisted dispersal syndromes. One-fifth of the pellets contained at least one intact propagule of aquatic invertebrates from seven taxa. Secondary dispersal by piscivorous birds may be vital to maintain connectivity in meta-populations and between river catchments, and in the movement of plants and invertebrates in response to climate change. Secondary dispersal pathways associated with complex food webs must be studied in detail if we are to understand species movements in a changing world.

description: Shaping modulation formats in multi-dimensional (MD) space is an effective approach to harvest spectral efficiency gains in both the additive white Gaussian noise (AWGN) channel and the optical fiber channel. In the first part of this paper, existing MD geometrically-shaped modulations for fiber optical communications are reviewed. It is shown that large gains can be obtained by exploiting correlation in the dimensions or/and by increasing the cardinality of the modulation format. Practical limitations and challenges are also discussed together with efficient solutions. In the second part, we extend the recently proposed four-dimensional (4D) modulation format family based on the constraint of orthant-symmetry to high spectrum efficiencies up to 10 bit/4D-sym by maximizing generalized mutual information for AWGN channel. Reach increases of up to 25% for a multi-span optical fiber transmission system are reported. Lastly,with the help of a recently introduced nonlinear interference (NLI) model, an optimization for designing nonlinear-tolerant 4D modulation formats is introduced for a single-span optical fiber system. Simulation results show that the proposed NLI model-based 4D modulation format could increase the effective SNRs by 0.25 dB with respect to the AWGN channel-optimal 4D modulation format.

description: Modeling approaches of suspended, rod-like particles and recent experimental data have shown that depletion forces display different signatures depending on the orientation of these particles. It has been shown that axial attraction of two rods yields contractile forces of 0.1pN that are independent of the relative axial shift of the two rods. Here, we measured depletion-caused interactions of actin bundles extending the phase space of single pairs of rods to a multi-particle system. In contrast to a filament pair, we found forces up to 3pN . Upon bundle relaxation forces decayed exponentially with a mean decay time of 3.4s . These different dynamics are explained within the frame of a mathematical model by taking pairwise interactions to a multi-filament scale. The macromolecular content employed for our experiments is well below the crowding of cells. Thus, we propose that arising forces can contribute to biological force generation without the need to convert chemical energy into mechanical work.

description: With the release of the third Gravitational-Wave Transient Catalogue (GWTC-3), 90 observations of compact-binary mergers by Virgo and LIGO detectors are confirmed. Some of these mergers are suspected to have occurred in star clusters. The density of black holes at the cores of these clusters is so high that mergers can occur through a few generations forming increasingly massive black holes. These conditions also make it possible for three black holes to interact, most likely via single-binary encounters. In this paper, we present a first study of how often such encounters can happen in nuclear star clusters (NSCs) as a function of redshift, and whether these encounters are observable by gravitational-wave (GW) detectors. This study focuses on effectively hyperbolic encounters leaving out the resonant encounters. We find that in NSCs single-binary encounters occur rarely compared to binary mergers, and that hyperbolic encounters most likely produce the strongest GW emission below the observation band of terrestrial GW detectors. While several of them can be expected to occur per year with peak energy in the LISA band, their amplitude is low, and detection by LISA seems improbable.

Overview

Una recapitulación y un recorrido nuevo de la autobiografía del autor y de la historia reciente de Japón: la omnipresencia del Hermano Gü, que inicia a un jovencísimo Kenzaburo en la poesía de Occidente y que acaba convirtiéndose en el Virgilio de esta nueva interpretación de La divina comedia ya que Dante es a esta novela lo que Homero al Ulises de Joyce, de esta lírica memoria que incluye la bomba atómica; los años de estudiante en Tokio, cuando siendo poco más que un adolescente se convirtió en una celebridad nacional por el premio Akutagawa concedido a su relato La presa; la boda y el nadmiento de su hijo «monstruoso», Hikari, que ocupará un lugar central en la vida y la obra del futuro premio Nobel; el viaje a México, tras las huellas de su admirado Malcolm Lowry, el autor de Bajo el volcán; la grotesca relación con su madre, que no le perdona el no haber vuelto a vivir a su isla y se niega a aclararle la verdad sobre la muerte de su padre; en fin, la visión sesgada sobre los dudosos privilegios que entraña la consagración literaria. La dulzura y la violencia que conviven en la voz de un hombre que se ha visto obligado a buscar lo sublime en lo deletéreo, a elevar a lo celestial no sólo las experiencias terrenales, sino también las infernales.

description: Restart has the potential of expediting or impeding the completion times of general random processes. Consequently, the issue of mean-performance takes center stage: quantifying how the application of restart on a process of interest impacts its completion-time's mean. Going beyond the mean, little is known on how restart affects stochasticity measures of the completion time. This paper is the first in a duo of studies that address this knowledge gap via: a comprehensive analysis that quantifies how sharp restart -- a keystone restart protocol -- impacts the completion-time's Boltzmann-Gibbs-Shannon entropy. The analysis establishes closed-form results for sharp restart with general timers, with fast timers (high-frequency resetting), and with slow timers (low-frequency resetting). These results share a common structure: comparing the completion-time's hazard rate to a flat benchmark -- the constant hazard rate of an exponential distribution whose entropy is equal to the completion-time's entropy. In addition, using an information-geometric approach based on Kullback-Leibler distances, the analysis establishes results that determine the very existence of timers with which the application of sharp restart decreases or increases the completion-time's entropy. Our work sheds first light on the intricate interplay between restart and randomness -- as gauged by the Boltzmann-Gibbs-Shannon entropy.

description: We calculate the observed luminosity and spectrum following the emergence of a relativistic shock wave from a stellar edges. Shock waves propagating at $0.6<Γ_\text{sh}β_\text{sh}$, where $Γ_\text{sh}$ is the shock Lorentz factor and $β_\text{sh}$ is its associated reduced velocity, heat the stellar envelope to temperatures exceeding $\sim 50$ keV, allowing for a vigorous production of electron and positron pairs. Pairs significantly increase the electron scattering optical depth and regulate the temperature through photon generation, producing distinct observational signatures in the escaping emission. Assuming Wien equilibrium, we find analytic expressions for the temperature and pair density profiles in the envelope immediately after shock passage, and compute the emission during the expansion phase. Our analysis shows that in pair loaded regions, photons are produced at a roughly uniform rest frame energy of $\sim 200$ keV, and reinforces previous estimates that the shock breakout signal will be detected as a short burst of energetic $γ$-ray photons, followed by a longer phase of X-ray emission. We test our model on a sample of low-luminosity gamma ray bursts using a closure relation between the $γ$-ray burst duration, the radiation temperature and the $γ$-ray isotropic equivalent energy, and find that some of the events are consistent with the relativistic shock breakout model. Finally, we apply our results to explosions in white dwarfs and neutron stars, and find that typical type Ia supernovae emit $\sim 10^{41}$ erg in the form of $\sim 1$ MeV photons.

description: Moving target shadows among video synthetic aperture radar (Video-SAR) images are always interfered by low scattering backgrounds and cluttered noises, causing poor detec-tion-tracking accuracy. Thus, a shadow-background-noise 3D spatial decomposition (SBN-3D-SD) model is proposed to enhance shadows for higher detection-tracking accuracy. It leverages the sparse property of shadows, the low-rank property of back-grounds, and the Gaussian property of noises to perform 3D spatial three-decomposition. It separates shadows from back-grounds and noises by the alternating direction method of multi-pliers (ADMM). Results on the Sandia National Laboratories (SNL) data verify its effectiveness. It boosts the shadow saliency from the qualitative and quantitative evaluation. It boosts the shadow detection accuracy of Faster R-CNN, RetinaNet and YOLOv3. It also boosts the shadow tracking accuracy of TransTrack, FairMOT and ByteTrack.

description: We aim to fully describe the distribution and location of dense molecular clouds in the giant molecular cloud complex W43. It was previously identified as one of the most massive star-forming regions in our Galaxy. To trace the moderately dense molecular clouds in the W43 region, we initiated W43-HERO, a large program using the IRAM 30 m telescope, which covers a wide dynamic range of scales from 0.3 to 140 pc. We obtained on-the-fly-maps in 13CO (2–1) and C18O (2–1) with a high spectral resolution of 0.1 km s-1 and a spatial resolution of 12′′. These maps cover an area of ~1.5 square degrees and include the two main clouds of W43 and the lower density gas surrounding them. A comparison to Galactic models and previous distance calculations confirms the location of W43 near the tangential point of the Scutum arm at approximately 6 kpc from the Sun. The resulting intensity cubes of the observed region are separated into subcubes, which are centered on single clouds and then analyzed in detail. The optical depth, excitation temperature, and H2 column density maps are derived out of the 13CO and C18O data. These results are then compared to those derived from Herschel dust maps. The mass of a typical cloud is several 104 M⊙ while the total mass in the dense molecular gas (>102 cm-3) in W43 is found to be ~1.9 × 106 M⊙. Probability distribution functions obtained from column density maps derived from molecular line data and Herschel imaging show a log-normal distribution for low column densities and a power-law tail for high densities. A flatter slope for the molecular line data probability distribution function may imply that those selectively show the gravitationally collapsing gas.

We first characterize the Purcell decay rate enhancement corresponding to the addition of the gold nanoshell as a function of the particle size and find a good agreement with the predictions of numerical simulations. Then, we show that the contribution corresponding to Förster resonance energy transfer is inhibited.

We pinpoint the single gravitational degree of freedom mediating the entanglement. We clarify why the distinction between longitudinal and transverse degrees of freedom is irrelevant for the interpretation of the results. We discuss the relation between the LOCC theorem and the interpretation of the effect, its different relevance for, respectively, the quantum gravity and quantum information communities, and the reason for the excitement raised by the prospect of detection.

description: This three-year research project began in January 2014 and investigated whether, during the Victorian period, the professions formed a distinct self-sustaining social group with its own mores and values. The project looked at 16,000 individuals drawn from census data for Alnwick, Brighton, Bristol, Dundee, Greenock, Leeds, Merthyr Tydfil, Morpeth, and Winchester. The research project was funded by the UK Economic & Social Research Council and was based at the Universities of Oxford and Northumbria.
Complete analytic solution of the geodesic equation in Schwarzschild--(anti) de Sitter space--times

description: The complete set of analytic solutions of the geodesic equation in a Schwarzschild--(anti) de Sitter space--time is presented. The solutions are derived from the Jacobi inversion problem restricted to the theta--divisor. In its final form the solutions can be expressed in terms of derivatives of Kleinian sigma functions. The solutions are completely classified by the structure of the zeros of the characteristic polynomial which depends on the energy, angular momentum, and the cosmological constant.

Overview

Sept ans après s'être mesurée au Chuchoteur, Mila Vasquez travaille aux Limbes, le département des personnes disparues. Incapable d'éprouver la moindre émotion et portant dans sa chair la marque des ténèbres, Mila excelle dans la recherche de ceux qui, un jour, se sont évanouis dans la nature. Elle seule ne peut oublier ces " victimes potentielles d'homicides ". Soudain, l'un d'eux réapparaît et tue. Un à un, ceux dont les portraits ornent les murs des Limbes, reviennent, transformés en assassins. Epaulée par l'agent spécial Simon Berish, expert en interrogatoires et féru d'anthropologie, Mila devra échafauder une hypothèse convaincante, solide, rationnelle. Une " hypothèse du mal ".

description: A long and intense gamma-ray burst (GRB) was detected by INTEGRAL on July 11 2012 with a duration of ~115s and fluence of 2.8x10^-4 erg cm^-2 in the 20 keV-8 MeV energy range. GRB 120711A was at z~1.405 and produced soft gamma-ray emission (>20 keV) for at least ~10 ks after the trigger. The GRB was observed by several ground-based telescopes that detected a powerful optical flash peaking at an R-band brightness of ~11.5 mag at ~126 s after the trigger. We present a comprehensive temporal and spectral analysis of the long-lasting soft gamma-ray emission detected in the 20-200 keV band with INTEGRAL, the Fermi/LAT post-GRB detection above 100 MeV, the soft X-ray afterglow from XMM-Newton, Chandra, and Swift and the optical/NIR detections from Watcher, Skynet, GROND, and REM. We modelled the long-lasting soft gamma-ray emission using the standard afterglow scenario, which indicates a forward shock origin. The combination of data extending from the NIR to GeV energies suggest that the emission is produced by a broken power-law spectrum consistent with synchrotron radiation. The afterglow is well modelled using a stratified wind-like environment with a density profile k~1.2, suggesting a massive star progenitor (i.e. Wolf-Rayet). The analysis of the reverse and forward shock emission reveals an initial Lorentz factor of ~120-340, a jet half-opening angle of ~2deg-5deg, and a baryon load of ~10^-5-10^-6 Msun consistent with the expectations of the fireball model when the emission is highly relativistic. Long-lasting soft gamma-ray emission from other INTEGRAL GRBs with high peak fluxes, such as GRB 041219A, was not detected, suggesting that a combination of high Lorentz factor, emission above 100 MeV, and possibly a powerful reverse shock are required. Similar long-lasting soft gamma-ray emission has recently been observed from the nearby and extremely bright Fermi/LAT burst GRB 130427A.

Overview

El ansiado desenlace de la trilogía de Trajano.En el año 53 a. C. el cónsul Craso cruzó el Éufrates para conquistar Oriente, pero su ejército fue destrozado en Carrhae. Una legión entera cayó prisionera de los partos. Nadie sabe a ciencia cierta qué pasó con aquella legión perdida.150 años después, Trajano está a punto de volver a cruzar el Éufrates. Los partos esperan al otro lado. Las tropas del César dudan. Temen terminar como la legión perdida.Pero Trajano no tiene miedo y emprende la mayor campaña militar de Roma hacia la victoria o hacia el desastre. Intrigas, batallas, dos mujeres adolescentes, idiomas extraños, Roma, Partia, India, China, dos Césares y una emperatriz se entrecruzan en el mayor relato épico del mundo antiguo, La legión perdida, la novela con la que Santiago Posteguillo cierra su aclamada trilogía sobre Trajano.Hay emperadores que terminan un reinado, pero otros cabalgan directos a la leyenda.

description: In this paper we present an application of the groupoid theory to the study of relevant case of material evolution phenomena, the \textit{process of morphogenesis}. Our theory is inspired by Walter Noll's theories of continuous distributions and provides a unifying and very simple framework of these phenomena. We present the explicit equation, the \textit{morphogenesis equation}, to calculate the \textit{material distributions} associated to this phenomenon.

Overview

Un delicioso clásico contemporáneo firmado por una de la escritoras más relevantes de la Italia del siglo XX. «La novela de Clara Sereni es auténtica, fotografía con sinceridad toda una época». La RepubblicaEsta novela en recetas —que recuerda a Natalia Ginzburg y su Léxico familiar y conecta con las mujeres de su genera­ción— nos presenta, con sabor único e inconfundible, un texto sabiamente elaborado, en el que los reconfortantes platos caseros se entremezclan con los más íntimos recuerdos e historias, todo salpimentado con un fino humor y, cuando lo requiere la ocasión, con los elementos dramáticos justos para conferirle robustez al guiso. En Casamante (1987) —convertido de inmediato en un gran éxito y referencia inexcusable de la literatura italiana del siglo XX—, como en otros libros que combinan la creación literaria y la gastronómica, la comida y el rito de su elaboración son al mismo tiempo una metáfora nutricia del viaje de autodescubrimiento de la narradora —nacida en una prominente familia judía dominada por personalidades fuertes y llenas de color— y la piedra angular de su vida.
Entanglement entropy in two dimensional string theory
Creators: name: Hartnoll, Sean A.
name: Mazenc, Edward
Publisher: name: arXiv
Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: To understand an emergent spacetime is to understand the emergence of locality. Entanglement entropy is a powerful diagnostic of locality, because locality leads to a large amount of short distance entanglement. Two dimensional string theory is among the very simplest instances of an emergent spatial dimension. We compute the entanglement entropy in the large $N$ matrix quantum mechanics dual to two dimensional string theory, in the semiclassical limit of weak string coupling. We isolate a logarithmically large, but finite, contribution that corresponds to the short distance entanglement of the tachyon field in the emergent spacetime. From the spacetime point of view, the entanglement is regulated by a nonperturbative `graininess' of space.
