description: We study the reaction-diffusion process $A + B \to \emptyset$ on uncorrelated scale-free networks analytically. By a mean-field ansatz we derive analytical expressions for the particle pair-correlations and the particle density. Expressing the time evolution of the particle density in terms of the instantaneous particle pair-correlations, we determine analytically the `jamming' effect which arises in the case of multicomponent, pair-wise reactions. Comparing the relevant terms within the differential equation for the particle density, we find that the `jamming' effect diminishes in the long-time, low-density limit. This even holds true for the hubs of the network, despite that the hubs dynamically attract the particles.

description: Many classical results in relativity theory concerning spherically symmetric space-times have easy generalizations to warped product space-times, with a two-dimensional Lorentzian base and arbitrary dimensional Riemannian fibers. We first give a systematic presentation of the main geometric constructions, with emphasis on the Kodama vector field and the Hawking energy; the construction is signature independent. This leads to proofs of general Birkhoff-type theorems for warped product manifolds; our theorems in particular apply to situations where the warped product manifold is not necessarily Einstein, and thus can be applied to solutions with matter content in general relativity. Next we specialize to the Lorentzian case and study the propagation of null expansions under the assumption of the dominant energy condition. We prove several non-existence results relating to the Yamabe class of the fibers, in the spirit of the black-hole topology theorem of Hawking-Galloway-Schoen. Finally we discuss the effect of the warped product ansatz on matter models. In particular we construct several cosmological solutions to the Einstein-Euler equations whose spatial geometry is generally not isotropic.

description: The epidemic caused by the SARS-CoV2 virus has affected economic activities in the world. In the case of Mexico, the confinement and social distancing measures have led to an economic contraction that affects small and medium-sized companies in cities and regions. Local governments have established government agendas with public policies that try to address the economic downturn. This document refers to the local agendas of 31 Federal Entities and Mexico City to quantify the diversity of economic policies with the Shannon Entropy Index and to compare local agendas with a statistical inference test. Results show that the agendas are diverse and borad in some cases, but they face the emergency in a similar way, so that the responses of local public administrations may have a limited effect on the economic problems generated by COVID19.

description: We present V and I CCD photometry of suspected low-surface brightness dwarf galaxies detected in a survey covering ~2.4 deg^2 around the central region of the Dorado group of galaxies. The low-surface brightness galaxies were chosen based on their sizes and magnitudes at the limiting isophote of 26.0Vμ. The selected galaxies have magnitudes brighter than V=20 (Mv=-11 for an assumed distance to the group of 17.2 Mpc), with central surface brightnesses \mu0>22.5 V mag/arcsec^2, scale lengths h>2'', and diameters > 14'' at the limiting isophote. Using these criteria, we identified 69 dwarf galaxy candidates. Four of them are large very low-surface brightness galaxies that were detected on a smoothed image, after masking high surface brightness objects. Monte Carlo simulations performed to estimate completeness, photometric uncertainties and to evaluate our ability to detect extended low-surface brightness galaxies show that the completeness fraction is, on average, > 80% for dwarf galaxies with $-1714''). The V-I colors of the dwarf candidates vary from -0.3 to 2.3 with a peak on V-I=0.98, suggesting a range of different stellar populations in these galaxies. The projected surface density of the dwarf galaxies shows a concentration towards the group center similar in extent to that found around five X-ray groups and the elliptical galaxy NGC1132 studied by Mulchaey and Zabludoff (1999), suggesting that the dwarf galaxies in Dorado are probably physically associated with the overall potential well of the group.

description: This paper concerns the finite-time blow-up and asymptotic behaviour of solutions to nonlinear Volterra integrodifferential equations. Our main contribution is to determine sharp estimates on the growth rates of both explosive and nonexplosive solutions for a class of equations with nonsingular kernels under weak hypotheses on the nonlinearity. In this superlinear setting we must be content with estimates of the form $\lim_{t\toτ}A(x(t),t) = 1$, where $τ$ is the blow-up time if solutions are explosive or $τ= \infty$ if solutions are global. Our estimates improve on the sharpness of results in the literature and we also recover well-known blow-up criteria via new methods.

description: Purpose: The purpose of this meta-analysis was to investigate the effects of augmentative and alternative communication (AAC) interventions that included aided AAC input (e.g., aided AAC modeling, aided language modeling, aided language stimulation, augmented input) on communicative outcomes (both comprehension and expression) for individuals with developmental disabilities who use AAC.Method: A systematic search resulted in the identification of 26 single-case experimental designs (88 participants) and 2 group experimental designs (103 participants). Studies were coded in terms of participants, intervention characteristics, dependent variables, outcomes, and quality of evidence.Results: AAC interventions that included aided AAC input in isolation, or as part of a multicomponent intervention, were found to be highly effective across participants of various ages, disabilities, and language skills. The interventions typically included aided AAC input in conjunction with expectant delay, direct prompting (e.g., spoken, gestural), contingent responding, and open-ended questions. The interventions were found to be highly effective in supporting both comprehension and expression across the domains of pragmatics, semantics, and morphosyntax. Outcomes related to expression were reported more often than outcomes related to comprehension.Conclusion: Aided AAC input may reduce input–output asymmetry and enhance expression and comprehension for individuals who use AAC; the evidence suggests that partners should utilize this strategy. Future research is needed to investigate the effects of AAC input (aided and unaided) on long-term language development for individuals who require AAC.

description: Light propagation in an atomic medium whose coupled electronic levels form a diamond-configuration exhibits a critical dependence on the input conditions. In particular, the relative phase of the input fields gives rise to interference phenomena in the electronic excitation whose interplay with relaxation processes determines the stationary state. We integrate numerically the Maxwell-Bloch equations and observe two metastable behaviors for the relative phase of the propagating fields corresponding to two possible interference phenomena. These phenomena are associated to separate types of response along propagation, minimize dissipation, and are due to atomic coherence. These behaviors could be studied in gases of isotopes of alkali-earth atoms with zero nuclear spin, and offer new perspectives in control techniques in quantum electronics.

description: BFORE is a NASA high-altitude ultra-long-duration balloon mission proposed to measure the cosmic microwave background (CMB) across half the sky during a 28-day mid-latitude flight launched from Wanaka, New Zealand. With the unique access to large angular scales and high frequencies provided by the balloon platform, BFORE will significantly improve measurements of the optical depth to reionization tau, breaking parameter degeneracies needed for a measurement of neutrino mass with the CMB. The large angular scale data will enable BFORE to hunt for the large-scale gravitational wave B-mode signal, as well as the degree-scale signal, each at the r~0.01 level. The balloon platform allows BFORE to map Galactic dust foregrounds at frequencies where they dominate, in order to robustly separate them from CMB signals measured by BFORE, in addition to complementing data from ground-based telescopes. The combination of frequencies will also lead to velocity measurements for thousands of galaxy clusters, as well as probing how star-forming galaxies populate dark matter halos. The mission will be the first near-space use of TES multichroic detectors (150/217 GHz and 280/353 GHz bands) using highly-multiplexed mSQUID microwave readout, raising the technical readiness level of both technologies.

description: We present near-infrared spectroscopy for a complete sample of 33 ultraluminous infrared galaxies at a resolution of R\approx 1000. Most of the wavelength range from 1.80-2.20 microns in the rest frame is covered, including the Pa-alpha and Br-gamma hydrogen recombination lines, and the molecular hydrogen vibration-rotation 1-0 S(1) and S(3) lines. Other species, such as He I, [Fe II], and [Si VI] appear in the spectra as well, in addition to a number of weaker molecular hydrogen lines. Nuclear extractions for each of the individual galaxies are presented here, along with spectra of secondary nuclei, where available. The Pa-alpha emission is seen to be highly concentrated on the nuclei, typically with very little emision extending beyond a radius of 1 kpc. Signatures of active nuclei are rare in the present sample, occurring in only two of the 33 galaxies. It is found that visual extinctions to the nuclei via the Pa-alpha/Br-gamma line ratio in excess of 10 magnitudes are relatively common among ULIRGs, and that visual extinctions greater than 25 mag are necessary to conceal a QSO emitting half the total bolometric luminosity. The vibration-rotation lines of molecular hydrogen appear to be predominantly thermal in origin, with effective temperatures generally around 2200 K. The relative nuclear velocities between double nucleus ULIRGs are investigated, through which it is inferred that the maximum deprojected velocity difference is about 200 km/s. This figure is lower than the velocities predicted by physical models of strong interactions/mergers of large, gas-rich galaxies.

Asymptotic Close To Optimal Joint Resource Allocation and Power Control in the Uplink of Two-cell Networks

description: In this paper, we investigate joint resource allocation and power control mechanisms for two-cell networks, where each cell has some sub-channels which should be allocated to some users. The main goal persuaded in the current work is finding the best power and sub-channel assignment strategies so that the associated sum-rate of network is maximized, while a minimum rate constraint is maintained by each user. The underlying optimization problem is a highly non-convex mixed integer and non-linear problem which does not yield a trivial solution. In this regard, to tackle the problem, using an approximate function which is quite tight at moderate to high signal to interference plus noise ratio (SINR) region, the problem is divided into two disjoint sub-channel assignment and power allocation problems. It is shown that having fixed the allocated power of each user, the subchannel assignment can be thought as a well-known assignment problem which can be effectively solved using the so-called Hungarian method. Then, the power allocation is analytically derived. Furthermore, it is shown that the power can be chosen from two extremal points of the maximum available power or the minimum power satisfying the rate constraint. Numerical results demonstrate the superiority of the proposed approach over the random selection strategy as well as the method proposed in [3] which is regarded as the best known method addressed in the literature.

description: We present the results of an extension of our previous work on large-scale simulations of dynamically triangulated toroidal random surfaces embedded in $R^3$ with extrinsic curvature. We find that the extrinsic-curvature specific heat peak ceases to grow on lattices with more than 576 nodes and that the location of the peak $\lam_c$ also stabilizes. The evidence for a true crumpling transition is still weak. If we assume it exists we can say that the finite-size scaling exponent $\frac α {νd}$ is very close to zero or negative. On the other hand our new data does rule out the observed peak as being a finite-size artifact of the persistence length becoming comparable to the extent of the lattice.

A comparative analysis of Community Archaeology based on two excavations in the south-east of the Iberian Peninsula: local community involvement and social context

description: This article presents the different socialisation methods of the excavation of two archaeological sites: the “Pago de Jarafí” (Lanteira, Granada), and “Mojácar la Vieja” (Mojácar, Almería). The projects involved the excavation of medieval Islamic settlements between 2014 and 2018 in two different social, economic and cultural contexts. The first, Lanteira, is a rural area of the Province of Granada that suffers from depopulation and ageing and a primary sector in economic crisis. The second, Mojácar, along the coast, has experienced a boom of tourism and the arrival of many foreign residents since the 1960s. This study analyses the methods and techniques to communicate and involve the local population during the entire archaeological excavation process and how these methods were adapted to each social reality. The research goes further to explore the link of the two local communities with their sites since the outset of the archaeological research and how they changed during the course of the excavation following application of a Community Archaeology. In questo articolo presenteremo le diverse metodologie che abbiamo applicato per la socializzazione di due siti archeologici durante il nostro intervento: il “Pago de Jarafí” (Lanteira, Granada) e “Mojácar la Vieja” (Mojácar, Almería). I progetti sono stati condotti tra gli anni 2014 e 2018 in insediamenti islamici medievali, in due diversi contesti sociali, economici e culturali. Il primo, Lanteira, si trova in una zona rurale della provincia di Granada che soffre di un problema di spopolamento e invecchiamento e con un’economia in crisi basata sul settore primario. Il secondo, Mojácar, in una zona costiera con un grande sviluppo del settore turistico e con un elevato numero di residenti stranieri dagli anni ’60 del XX secolo. Il lavoro analizza le metodologie e le tecniche per comunicare e coinvolgere la popolazione locale durante l’intero processo di scavo archeologico e come queste metodologie si siano adattate alla realtà sociale di entrambi i comuni. Esporremo il legame che queste comunità locali hanno avuto con i relativi siti fin dall’inizio della ricerca archeologica e come tale legame sia cambiato durante lo scavo a seguito dello sviluppo di un’archeologia pubblica e comunitaria.

description: We autonomously stabilize arbitrary states of a qubit through parametric modulation of the coupling between a fixed frequency qubit and resonator. The coupling modulation is achieved with a tunable coupler design, in which the qubit and the resonator are connected in parallel to a superconducting quantum interference device. This allows for quasi-static tuning of the qubit-cavity coupling strength from 12 MHz to more than 300 MHz. Additionally, the coupling can be dynamically modulated, allowing for single photon exchange in 6 ns. Qubit coherence times exceeding 20 $μ$s are maintained over the majority of the range of tuning, limited primarily by the Purcell effect. The parametric stabilization technique realized using the tunable coupler involves engineering the qubit bath through a combination of photon non-conserving sideband interactions realized by flux modulation, and direct qubit Rabi driving. We demonstrate that the qubit can be stabilized to arbitrary states on the Bloch sphere with a worst-case fidelity exceeding 80 %.

description: La empresa Uber comenzó sus operaciones en la Ciudad de México en agosto de 2013. A partir de ese momento, hubo manifestaciones a favor y en contra de este nuevo servicio en el mercado de transporte de la ciudad. El 15 de julio de 2015, el Gobierno de la Ciudad de México emitió un acuerdo administrativo que reguló los servicios de Uber y empresas semejantes para prestar este tipo de servicio de forma legal, lo que convirtió a la Ciudad de México en una de las primeras urbes del mundo en permitir legalmente la operación de este tipo de compañías de transporte.1 A dos años de vigencia de esta nueva regulación, otras ciudades en México han permitido, obstaculizado o ignorado en sus marcos jurídicos locales el servicio de transporte de estos nuevos agentes económicos.Con el estudio de estas nuevas regulaciones locales en México y con la utilización de los enfoques del análisis económico del derecho y de las políticas públicas, el presente trabajo tiene tres propósitos, el primero es retomar el modelo de decisión racional del consumidor de una investigación previa para conceptualizar el problema público del tráfico y evaluar las regulaciones locales, el segundo es explicar los marcos jurídicos locales en México con base en la interpretación jurídica de la Suprema Corte de Justicia de la Nación y el tercero es aplicar tres pruebas estadísticas para encontrar evidencia de significancia estadística en la diferencia y la variación de precios entre los taxis de sitio y los precios de la empresa Uber con el objetivo de analizar la ganancia de los consumidores y una posible fijación de precios no competitiva de los taxis de sitio.

description: We report transverse-field (TF) muon spin rotation experiments on single crystals of the topological superconductor Sr$_x$Bi$_2$Se$_3$ with nominal concentrations $x=0.15$ and $0.18$ ($T_c \sim 3$ K). The TF spectra ($B= 10$ mT), measured after cooling to below $T_c$ in field, did not show any additional damping of the muon precession signal due to the flux line lattice within the experimental uncertainty. This puts a lower bound on the magnetic penetration depth $λ\geq 2.3 ~μ$m. However, when we induce disorder in the vortex lattice by changing the magnetic field below $T_c$ a sizeable damping rate is obtained for $T \rightarrow 0$. The data provide microscopic evidence for a superconducting volume fraction of $\sim 70~ \%$ in the $x=0.18$ crystal and thus bulk superconductivity.

As a result, we were able to obtain periods for all NGC 6229 variables, with the exception of five stars from the Borissova et al. (1997) candidate list located very close to the cluster center. Two variable stars suspected by Carney, Fullton, & Trammell (1991) are first-overtone RR Lyrae (RRc) stars, whereas seven of the 12 candidates from Borissova et al. (1997) are confirmed variables -- three of them being fundamental RR Lyrae (RRab) pulsators, two first-overtone pulsators, one eclipsing binary (most likely an Algol system) and one bright star whose variability status could not be satisfactorily determined. A new image subtraction method (ISM) suggested by Alard (1999) has been employed which, together with the Welch & Stetson (1993) technique, has allowed us to discover twelve new RR Lyrae variables in the cluster, for which ephemerides are provided. Ten of these are RRab's, whereas the other two are RRc's. As originally suggested by Mayer (1961), NGC 6229 is clearly an Oosterhoff type I globular cluster. We also confirm that V8 is a Population II Cepheid of the W Virginis type, and suspect that this is the case for V22 as well. The physical properties of the NGC 6229 RR Lyrae population are compared against those of M3 (NGC 5272) using several different methods, including a standard period-shift analysis. Possible differences between these two clusters are discussed.

description: Commercial quartz oscillators of the tuning-fork type with a resonant frequency of ~32 kHz have been investigated in helium liquids. The oscillators are found to have at best Q values in the range 10^5-10^6, when measured in vacuum below 1.5 K. However, the variability is large and for very low temperature operation the sensor has to be preselected. We explore their properties in the regime of linear viscous hydrodynamic response in normal and superfluid 3He and 4He, by comparing measurements to the hydrodynamic model of the sensor.

description: We study the effective theory of decoupling of a charm quark at low energies. We do this by simulating a model, QCD with two mass-degenerate charm quarks. At leading order the effective theory is a pure gauge theory. By computing ratios of hadronic scales we have direct access to the power corrections in the effective theory. We show that these corrections follow the expected leading behavior, which is quadratic in the inverse charm quark mass.

description: Percorsi bioGrafici è un progetto di archeologia pubblica condotto congiuntamente dal Comune di Monforte San Giorgio e dal Dipartimento di Scienze Storiche e dei Beni Culturali dell’Università di Siena che ha come obiettivo la lettura in chiave archeologica della complessità storica di un paese “medio” della Sicilia contemporanea. Il progetto è inteso a comprendere – e soprattutto far comprendere alla comunità di eredità dei Monfortesi – quando, come e perché questo paese della Sicilia, dell’Italia Meridionale e del Mediterraneo ha assunto la sua conformazione attuale. Su questa base di partenza, attività specifiche di miglioramento sono state progettate e realizzate in costante collaborazione con la comunità locale: a) riqualificazione di elementi specifici del tessuto urbano attraverso pratiche di valorizzazione leggera; b) realizzazione di percorsi tematici, fruibili anche attraverso app di telefonia cellulare; c) attività di archeologia partecipata con il coinvolgimento di scuole, associazioni culturali e singoli cittadini; d) rigenerazione del rapporto tra uomini e cose nello spazio urbano, con l’obiettivo di indurre comportamenti virtuosi e buone pratiche di rispetto e tutela del proprio spazio di vita e di relazione. Percorsi bioGraficiis a public archaeology project carried out jointly by the Municipality of Monforte San Giorgio and the Department of History and Cultural Heritage of the University of Siena, and aimed to an archaeological assessment of the historical complexity of an “average” small town in contemporary Sicily. The project is intended to understand – and above all to make the local heritage community understand – when, how and why this small town of Sicily, like many others in Southern Italy and in the Mediterranean, has assumed its current conformation. Starting from this basis, specific activities were designed and implemented with the cooperation of the local community: a) participatory archaeology activities, involving schools, cultural associations and individual citizens; b) realization of thematic routes, usable also through mobile phone apps; c) re-qualification of specific elements of the urban fabric; d) regeneration of the relationship between men and things in the urban space, with the aim of inducing virtuous behaviors and best practices of respect and protection of one’s living space and relationship.

description: The Allan variance of signal and reference frequencies is measured by a least-squares fit of the output of two analog-to-digital converters (ADC's) to ideal sine waves. The difference in the fit phase of the two channels generates the timing data needed for the Allan variance. The fits are performed at the signal frequency ($\approx 10 $ MHz) without the use of heterodyning. Experimental data from a modified digital oscilloscope yields a residual Allan deviation of $3 \times 10^{-13}/τ$, where $τ$ is the observation time in sec. This corresponds to a standard deviation in time of $

description: Uomini e cose a Vignale è un progetto di archeologia pubblica e condivisa in corso da oltre un decennio nel territorio di Riotorto, un quartiere isolato del comune di Piombino, in Toscana. Il progetto, originato da uno scavo archeologico condotto dall’Università di Siena sul sito di una villa romana con annessa stazione di posta, si è progressivamente strutturato in una operazione di archeologia pubblica, con il coinvolgimento diretto di una parte sostanziale della comunità di riferimento (scuole, associazioni culturali, singoli cittadini), di gruppi via via più ampi di una comunità più allargata (residenti nei territori contermini, cittadini “temporanei” rappresentati dai numerosi turisti che frequentano la zona) e di numerose realtà imprenditoriali locali. Il progetto ha consentito di sviluppare una interazione profonda con il territorio, di definire i numerosi e diversificati portatori di interesse e di mettere progressivamente a fuoco potenzialità da cogliere (per esempio in termini di crowdfunding e di crowdsourcing) e criticità da affrontare, in particolare sotto il profilo giuridico-gestionale. Il presente contributo intende discutere in maniera articolata le tante questioni emerse nel corso di questa esperienza, sviluppando la riflessione essenzialmente a partire dal concetto di sostenibilità nel tempo del progetto stesso. Uomini e Cose a Vignale (Peoples and Things at Vignale) is a community archaeology project based in the territory of Riotorto, a rural neighbourhood of the Municipality of Piombino, in Tuscany. Since 2004, the University of Siena carried out the excavation of a Roman villa and mansio and established deep connections with the surrounding area. Thanks to the direct involvement of local stakeholders – intended both as members of the resident community (i.e. schools, cultural associations, companies and laypeople) and of bystanders (i.e. tourists) – the project developed specific traits that may considered innovative, especially in terms of economic management largely based on crowdfunding and crowdsourcing strategies. Introducing some of these traits and presenting a recent evaluation of the project, the aim of this paper is to critically address the social, intellectual and economic sustainability of Uomini e Cose a Vignale over time.
