description: By simultaneously coupling multiple two-level artificial atoms to two superconducting resonators, we design a quantum switch that tunes the resonator-resonator coupling strength from zero to a large value proportional to the number of qubits. This process is implemented by engineering the qubits into different subradiant states, where the microwave photons decay from different qubits destructively interfere with each other such that the resonator-resonator coupling strength keeps stable in an open environment. Based on a three-step control scheme, we switch the coupling strength among different values within nanoseconds without changing the transition frequency of the qubits. We also apply the quantum switch to a network of superconducting resonators, and demonstrate its potential applications in quantum simulation and quantum information storage and processing.

description: The current framework for U.S. Environmental Protection Agency regulation of water quality in community drinking water supplies consists of sequential rules for either single contaminants or small groups of similar contaminants. For both substantive and pragmatic reasons, promulgating less frequent rules for larger contaminant classes may be desirable. Such a change would require the expansion of existing regulatory evaluation technologies to account for joint occurrence distributions of the contaminants. This paper extends existing methods for modeling the distributions of a single contaminant in community water system source waters to the simultaneous consideration of multiple contaminants. It considers alternatives for addressing the implementation difficulties inherent in the multivariate setting, providing solutions of general methodological interest. Through case studies involving arsenic, sulfate, magnesium and calcium, it shows how jointly modeling contaminants provides better fit and predictive power than marginal models, and emphasizes how inference about critical regulatory quantities can be improved through joint modeling. The methods presented in this paper make significant progress in redressing several shortcomings of existing analyses.

description: In this paper, we investigate the role of gravito-inertial effects on the Casimir energy of a massless scalar field confined between two parallel plates orbiting a static and zero tidal Schwarzschild-like wormhole, at zero temperature. Firstly, we obtain the metric in isotropic coordinates, finding the allowed angular velocities and the circular orbit radii for a material particle as well as for the photon. Following, we compute the changes induced by both gravity and rotation of the plates in the energy density of the quantum vacuum fluctuations associated to the scalar field, in the zero tidal approximation inside the cavity. Finally, the Casimir energy obtained for some these wormholes are graphically compared between themselves and also with those ones related to an Ellis wormhole as well as to a Schwarzschild black hole. With this, the gravito-inertial effects on the quantum vacuum fluctuations analyzed in this work allow to recognize and identify both the geometry and topology of the spacetime associated to each one of these objects.

description: A deep understanding of the Epoch of Reionization is still missing in our knowledge of the universe. While future probes will allow us to test the precise evolution of the free electron fraction from redshifts between $z\simeq 6$ and $z\simeq 20$, at present one could ask what kind of reionization processes are allowed by present Cosmic Microwave Background temperature and polarization measurements. An early contribution to reionization could imply a departure from the standard picture where star formation determines the reionization onset. BBy considering a broad class of possible reionization parameterizations, we find that current data do not require an early reionization component in our universe and that only one marginal class of models, based on a particular realization of reionization, may point to that. In addition, the frequentist Akaike Information Criterion (AIC) provides strong evidence against alternative reionization histories, favoring the most simple reionization scenario, which describes reionization by means of only one (constant) reionization optical depth $τ$.

description: We study the phase diagram of an imbalanced two-component Fermi gas in optical lattices of 1-3 dimensions, considering the possibilities of the FFLO, Sarma/breached pair, BCS and normal states as well as phase separation, at finite and zero temperatures. In particular, phase diagrams with respect to average chemical potential and the chemical potential difference of the two components are considered, because this gives the essential information about the shell structures of phases that will occur in presence of an additional (harmonic) confinement. These phase diagrams in 1, 2 and 3 dimensions show in a striking way the effect of Van Hove singularities on the FFLO state. Although we focus on population imbalanced gases, the results are relevant also for the (effective) mass imbalanced case. We demonstrate by LDA calculations that various shell structures such as normal-FFLO-BCS-FFLO-normal, or FFLO-normal, are possible in presence of a background harmonic trap. The phases are reflected in noise correlations: especially in 1D the unpaired atoms leave a clear signature of the FFLO state as a zero-correlation area (``breach'') within the Fermi sea. This strong signature occurs both for a 1D lattice as well as for a 1D continuum. We also discuss the effect of Hartree energies and the Gorkov correction on the phase diagrams.

Quantum reflection and dwell times of metastable states

description: The concept of phase and dwell times used in tunneling is extended to quantum collisions to derive a relation between the phase and dwell time delays in scattering. This relation can be used to remove the near threshold s-wave singularities in the Wigner-Eisenbud delay times and amounts to an extension of the concept of quantum reflection to strong interactions. Dwell time delay emerges as the quantity which gives the correct behaviour of the density of states of a metastable state at all energies. This fact is demonstrated by investigating some recently found metastable states of mesic-nuclei.

A statistical mechanical approach to restricted integer partition functions

Year: 2018
Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)

description: The main aim of this paper is twofold: (1) Suggesting a statistical mechanical approach to the calculation of the generating function of restricted integer partition functions which count the number of partitions --- a way of writing an integer as a sum of other integers under certain restrictions. In this approach, the generating function of restricted integer partition functions is constructed from the canonical partition functions of various quantum gases. (2) Introducing a new type of restricted integer partition functions corresponding to general statistics which is a generalization of Gentile statistics in statistical mechanics; many kinds of restricted integer partition functions are special cases of this restricted integer partition function. Moreover, with statistical mechanics as a bridge, we reveals a mathematical fact: the generating function of restricted integer partition function is just the symmetric function which is a class of functions being invariant under the action of permutation groups. Using the approach, we provide some expressions of restricted integer partition functions as examples.
Infinite Choice Transferable Utility Games and a n Application to Wage Distribution in Firms

description: Much work has been done on extending the Shapley value tofinite multi-choice transferable utility games. However, little of this work has dealt with infinite choice games. Thispaper extends the Shapley value to infinite choice games and shows that this Shapley value satisfies six simple axioms: weak symmetry, efficiency, additivity, the null worker axiom,no poy for no work and strong scale invariance. In addition, this paper gives a similar axiomatizationfor extending the Shapley value tofinite multi-choice games. Justification for using this axiomatization for wage distribution infirm problems is given and compared to thejustificati onfor the Aumann-Shapley value. Taking advantage of thefact that total-factor productivity ispositively correlated withfirm size, this paper uses 2012 Current Population Survey data to test if workers ore being paid their expected Shapley value in earnings. Union membership is found to have a positive effect on bargaining strength that is statistically significant at the 9596 confidence level.

description: In a dynamical system, the transition between reactants and products is typically mediated by an energy barrier whose properties determine the corresponding pathways and rates. The latter is the flux through a dividing surface (DS) between the two corresponding regions and it is exact only if it is free of recrossings. For time-independent barriers, the DS can be attached to the top of the corresponding saddle point of the potential energy surface, and in time-dependent systems, the DS is a moving object. The precise determination of reaction rates, eg using transition state theory, requires the actual construction of a DS for a given saddle geometry which is in general a demanding methodical and computational task, especially in high-dimensional systems. In this paper, we demonstrate how such time-dependent, global, and recrossing-free DSs can be constructed using neural networks. In our approach, the neural network uses the bath coordinates and time as input and it is trained in a way that its output provides the position of the DS along the reaction coordinate. An advantage of this procedure is that, once the neural network is trained, the complete information about the dynamical phase space separation is stored in the network's parameters, and a precise distinction between reactants and products can be made for all possible system configurations, all times, and with little computational effort. We demonstrate this general method for two- and three-dimensional systems, and explain its straightforward extension to even more degrees of freedom.

description:

Il tema di questa pubblicazione scientifica educativa e divulgativa intende raggiungere il general pubblico e le persone legate al mondo della comunicazione scientifica, con alcuni esempi dello studio dei pigmenti dal passato al presente dell'umanità. Con essa illustriamo informazioni sulla conoscenza, gli usi, i processi di produzione o la scelta dei materiali, sia che si tratti di coloranti minerali e ottenuti da piante, insetti e molluschi. In questo libro, tra l'altro, approfondiamo lo sviluppo dell'archeometria, come scienza che identifica la composizione chimica e fisica di pigmenti e colori con esempi provenienti da Cile, Colombia e Messico. Specifichiamo la cromaticità dei colori nelle manifestazioni di arte rupestre su scala globale. Ripercorriamo brevemente l'uso di alcuni colori da parte di alcuni pueblos nativi e contemporanee che attualmente utilizzano la pittura del corpo come forma d'identità. Viaggiamo in contesti megalitici e in altre culture attraverso l'uso del cinabro. Conosciamo l'"invenzione" di alcuni colori come il blu in diverse regioni del mondo. Infine, approfondiamo l'uso di alcuni pigmenti organici utilizzati nella produzione di tessuti.

description: The determination of evolutionary relationships is a fundamental problem in evolutionary biology. Genome arrangement data is potentially more informative than DNA sequence data for inferring evolutionary relationships among distantly related taxa. We describe a Bayesian framework for phylogenetic inference from mitochondrial genome arrangement data using Markov chain Monte Carlo methods. We apply the method to assess evolutionary relationships among eight animal phyla.

description: The analysis of domain wall dynamics is often simplified to one dimensional physics. For domain walls in thin films, more realistic approaches require the description as two dimensional objects. This includes the study of vortices and curvatures along the domain walls as well as the influence of boundary effects. Here we provide a theory in terms of soft modes that allows to analytically study the physics of extended domain walls and their stability. By considering irregular shaped skyrmions as closed domain walls, we analyze their plasticity and compare their dynamics with those of circular skyrmions. Our theory directly provides an analytical description of the the excitation modes of magnetic skyrmions, previously only accessible by sophisticated micromagnetic numerical calculations and spectral analysis. These analytical expressions provide the scaling behaviour of the different physics on parameters that experiments can test.

description: La tesis titulada “Humedal Gualí: Procesos de apropiación, uso y defensa del territorio” tiene como tema central las formas de apropiación, uso y defensa que tiene la comunidad de Funza y Mosquera frente al Humedal Gualí, ya que este ecosistema es parte activa de los procesos de desarrollo y construcción cultural. En este momento las condiciones de deterioro del medio ambiente han generado un gran impacto, ya que la ausencia de consciencia social y ambiental han impulsado alteraciones a los ecosistemas que, en muchos casos, son irreversibles. En ese sentido, se identificaron formas de apropiación sobre el humedal tales como la utilización del humedal para actividades agrícolas y ganaderas o el uso del suelo para proyectos de construcción de viviendas. Así mismo, el sector industrial también tiene apropiaciones particulares, como la extracción de recursos hídricos o vertedero de sustancias químicas y desechos. Por otro lado, se contraponen acciones colectivas en defensa del humedal, así como una educación y visibilización sobre los fines ambientalistas del Humedal El Gualí. En síntesis, dichas acciones enmarcadas en la apropiación tienen representaciones particulares que deben ser identificadas para establecer diferencias y acuerdos que permitan comprender expresiones y proponer un uso integral del territorio.
description: The thesis titled “Gualí Wetland: Processes of appropriation, use and defense of the territory” has as central theme the forms of appropriation, use and defense that the communities of Funza and Mosquera have against the Gualí Wetland, since this ecosystem is an active part of their processes of development and cultural construction. Currently, the deteriorating conditions of the environment have generated a great impact, since the absence of social and environmental awareness has driven alterations to ecosystems that, in many cases, are irreversible. In this sense, some forms of appropriation of the wetland were identified, such as the use of the wetland for agricultural and livestock activities or the use of land for housing projects. The industrial sector also has particular forms of appropriation, such as the extraction of water resources or the dumping of chemicals and waste. On the other hand, there are collective actions in defense of the wetland, as well as education and visibility of the environmental purposes of the El Gualí Wetland. In summary, these actions framed in appropriation have particular representations that must be identified to establish differences and agreements that allow the understanding of expressions and to propose a comprehensive use of the territory.

description: Successful implementation of a brain-computer interface depends critically on the subject's ability to learn how to modulate the neurons controlling the device. However, the subject's learning process is probably the least understood aspect of the control loop. How should training be adjusted to facilitate dexterous control of a prosthetic device? An effective training schedule should manipulate the difficulty of the task to provide enough information to guide improvement without overwhelming the subject. In this paper, we introduce a bayesian framework for modeling the closed-loop BCI learning process that treats the subject as a bandwidth-limited communication channel. We then develop an adaptive algorithm to find the optimal difficulty-schedule for performance improvement. Simulation results demonstrate that our algorithm yields faster learning rates than several other heuristic training schedules, and provides insight into the factors that might affect the learning process.

description: We evolve models of rotating massive stars up to the stage of iron core collapse using the MESA code and find a shell with a mixed composition of primarily helium and oxygen in some cases. In the parameter space of initial masses of 13-40 Mo and initial rotation velocities of 0-450 km/s that we investigate, we find a mixed helium-oxygen shell with a significant mass only for a small fraction of the models. While the shell is formed due to rotational mixing, the pre-collapse rotation rate is not very high, as required for an energetic collapse-induced thermonuclear explosion. Our results suggest that the collapse-induced thermonuclear explosion mechanism that was revisited recently can account for at most a small fraction of core-collapse supernovae. The presence of such a mixed helium-oxygen shell still might have some implications for core-collapse supernovae, such as some nucleosynthesis processes when jets are present, or might result in peculiar sub-luminous core-collapse supernovae.

Transition démographique et développement vont-ils de pair? Revue analytique du cas de l'Afrique Subsaharienne
Creators: name: Thierry, Santime
Publisher: name: My University
Year: 2020

description: Contexte : La persistance des taux de fécondité élevés dans une grande partie de pays africains retarde leur transition démographique. Les taux de mortalité et de fécondité en Afrique ont tous deux connu une diminution au cours des dernières décennies mais la baisse de la mortalité a été beaucoup plus rapide que celle de la fécondité. De nombreux auteurs soutiennent que la transition démographique est une condition nécessaire au développement alors que d’autres auteurs remettent en question cette assertion. Ce travail étudie le rôle de la transition démographique dans le développement humain des pays d’Afrique Subsaharienne. Objectifs : Cette recherche vise à comprendre et analyser le rôle que peut jouer la transition démographique dans l’amélioration du développement humain des pays d’Afrique Subsaharienne. À partir d’un échantillon de pays divisés en deux catégories, nous essayons de voir si un lien peut être établi entre la réussite de la transition démographique et un meilleur développement humain et inversement, si le retard dans la transition démographique est plus ou moins associé à un faible niveau de développement humain. Méthodes : Cette analyse est une recherche mixte, combinant des données quantitatives et des facteurs plus qualitatifs. Il s’agit d’un travail comparatif dans lequel nous comparons les performances en termes de développement humain des pays à faible fécondité par rapport aux pays à forte fécondité. Nos données sont essentiellement issues de sources secondaires, notamment la base de données de la Banque Mondiale et la littérature spécialisée disponible. Résultats : Nos résultats indiquent un lien apparent entre la transition démographique et le développement humain. Les pays de notre échantillon ayant réussi leur transition démographique jouissent d’un meilleur niveau de développement humain que ceux qui peinent encore à réaliser la transition. Conclusion : Cette recherche permet d’illustrer le rôle de variables démographiques dans la marche vers le développement. La réalisation de la transition démographique n’est certes pas synonyme de développement ou d’émergence économique ipso facto, mais il appert que le maintien de taux de fécondité élevés hypothèque à bien des égards les perspectives de développement. Notre recherche soutient que pour bénéficier du dividende démographique, il est important que les pays africains offrent à leur population une éducation de qualité, des systèmes de santé adéquats et des perspectives raisonnables d’emplois. Parallèlement, il est nécessaire de consentir des investissements soutenus dans la planification familiale, la santé sexuelle et reproductive, l’autonomisation des femmes et jeunes filles et travailler à mettre fin aux pratiques dégradantes comme les mutilations génitales féminines (MGF) et les mariages forcés, entre autres.

description: We investigate the LHC discovery prospects for a heavy Higgs boson decaying into the Standard Model Higgs boson and additional weak bosons. We consider a generic model-independent new physics configuration where this decay proceeds via a cascade involving other intermediate scalar bosons and focus on an LHC final-state signature comprised either of four b-jets and two charged leptons or of four charged leptons and two b-jets. We design two analyses of the corresponding signals, and demonstrate that a 5σ discovery at the 14 TeV LHC is possible for various combinations of the parent and daughter Higgs-boson masses. We moreover find that the Standard Model backgrounds can be sufficiently rejected to guarantee the reconstrution of the parent Higgs boson mass. We apply our analyses to the Type-II Two-Higgs-Doublet Model and identify the regions of the parameter space to which the LHC is sensitive.

description: We introduce a Bayesian approach to multiple testing. The method is an extension of the false discovery rate (FDR) method due to Benjamini and Hochberg (1995). We also examine the empirical Bayes approach to simultaneous inference proposed by Efron, Tibshirani, Storey and Tusher (2001). We show that, in contrast to the single hypothesis case - where Bayes and frequentist tests do not agree even asymptotically - in the multiple testing case we do have asymptotic agreement.

description: The radio and X-rays that followed GW170817 increased gradually over $\sim~100$ days, resembling the radio flare predicted to arise from the interaction of a binary neutron star merger outflow with the ISM \citep{nakar2011}. Considering a blast wave moving with a Lorentz factor $Γ$, we show that an off-axis observer, namely an observer at $θ_{obs}>1/Γ$, sees a light curve rising faster than $F_ν\propto t^3$. Therefore, the observed rise, $F_ν\propto~t^{0.78}$, implies that at all times we have seen an on-axis emission. Namely, the emitting matter was within $θ_{obs}<1/Γ$ at the time of observations (even if it was off-axis beforehand). The observations tightly constrain the blast wave Lorentz factor: $Γ\sim(1.5-7)(t/10~{\rm day})^{-0.21}$.The isotropic equivalent energy in the observed region increases with time, $E_{iso}\sim~10^{50}{\rm~erg} ~(t/150~{\rm day})^{1.3}$, implying that the outflow was structured. The energy increase can arise from a slower material moving behind the blast wave or from a matter moving at larger angles that has slowed down. Such a structure could have different origins, however, the only physically motivated one, proposed so far, is the interaction of a relativistic jet with the ejecta and the resulting cocoon. The jet could have been choked or successful. In the latter case, it has produced a short GRB pointing elsewhere (this successful jet-cocoon system is sometimes called a "structured jet"). Although circumstantial evidence disfavors a successful jet, the jet fate cannot be decisively determined from current observations. The light curve alone may not be sufficient to resolve this question, since both chocked and successful jets can lead to a gradual rise to a peak, followed by a decay. Therefore, the recent turnover of the light curve does not necessitate a successful jet.
description: Revised to include a discussion the implication of the observed flattening of the light curve and compare them with predictions

description: Background: Prostate cancer is a substantial public health concern; however, in recent years, national guidelines have recommended against prostate cancer screening. We sought to determine if prostate biopsy incidence has changed over time in Ontario. We hypothesized that there has been a decrease in the incidence of prostate biopsy in recent years. Methods: This cohort study used population-based administrative databases from Ontario, Canada. We used a diagnostic code to identify if a patient received his first prostate biopsy between 1992 and 2012 (the last year for which records in the Ontario Cancer Registry were complete). Age-stratified and overall age-standardized incidences of prostate biopsy were determined. Changes over time in prostate biopsy incidence and the proportion of prostate biopsies that showed malignant disease were examined using negative binomial regression adjusting for patient age. Results: We identified 231 266 Ontario men aged 40 years and older who received their first prostate biopsy between 1992 and 2014. Up to 2007, biopsy incidence increased in younger men, but decreased in older men. After 2007, biopsy incidence decreased in all age groups, with the age-standardized overall biopsy incidence dropping from 480 per 100 000 in 2007 to 250 per 100 000 in 2014. A total of 84 149 (39%) incident biopsies showed malignant disease. The proportion of biopsies classified as showing malignant disease increased during the study period, from 25.6% in 1992 to 49.2% in 2010, and then decreased in all age groups. Interpretation: Previously increasing biopsy rates decreased significantly in recent years, suggesting that prostate cancer screening in Ontario may be changing.
El paraconcurso en el sector salud. Reflexiones sobre la intervención de las entidades administradoras de planes de beneficios

description: En este trabajo se estudia la forma en cómo la inexistencia de un régimen especial para tomar posesión de las Entidades Administradoras de Planes de Beneficios, genera muchas dificultades a los acreedores de la entidad sobre la cual se ha tomado la medida. Dado que a a estas entidades se les aplica lo reglado en el Estatuto Orgánico Financiero, resulta necesario evidenciar algunas de las normas que no son compatibles con la actividad y operación de las entidades del sector salud. Para esto de forma resumida se explicará alguna de las medidas especiales preventivas, el proceso de toma de posesión, y se señalará de forma concreta las disposiciones inconvenientes para los acreedores, en especial aquellas que impactan a las IPS, quienes son los acreedores que sostienen el gran peso del sistema de salud, al ser los prestadores directos del servicio. Es urgente el estudio de la regulación de toma posesión de las EAPB, máxime si desde el año 2011, la Superintendencia Nacional de Salud ha ordenado la liquidación de más de 20 EPS, las cuales estaban a cargo del aseguramiento de poco más del 25% de la población asegurada para el 2014.
description: This paper studies how the non-existence of a special bankruptcy process of the Administration Entities of Benefit Plans generates many difficulties for the creditors of the entity on which the measure has been taken. Since the provisions of the Organic Financial Statute are applied to these entities, it is necessary to demonstrate some of the regulations that are not compatible with the activity and operation of entities in the health sector. For this, in a summarized way, some of the special preventive measures will be explained, the process of taking possession, and the provisions that are inconvenient for the creditors will be pointed out concretely, especially those that impact the Hospitals, who are the creditors that hold the impact of the health system, as they are the direct providers of the service. The study of the regulation of taking possession of the EAPB is urgent, especially if since 2011, the National Superintendence of Health has ordered the liquidation of more than 20 EPS, which were in charge of the insurance of little more than 25% of the insured population for 2014.

description: Statistical decision theory can be a valuable tool for policy-making decisions. In particular, environmental problems often benefit from the application of Bayesian and decision-theoretic techniques that address the uncertain nature of problems in the environmental and ecological sciences. This paper discusses aspects of implementing statistical decision-making tools in situations where uncertainty is present, looking at issues such as elicitation of prior distributions, covariate allocation, formulation of loss functions, and minimization of expected losses subject to cooperation constraints. These ideas are illustrated through two case studies in environmental remediation.

description: A plausible mechanism of thermalization in isolated quantum systems is based on the strong version of the eigenstate thermalization hypothesis (ETH), which states that all the energy eigenstates in the microcanonical energy shell have thermal properties. We numerically investigate the ETH by focusing on the large deviation property, which directly evaluates the ratio of athermal energy eigenstates in the energy shell. As a consequence, we have systematically confirmed that the strong ETH is indeed true even for near-integrable systems, where we found that the finite-size scaling of the ratio of athermal eigenstates is double exponential. Our result illuminates universal behavior of quantum chaos, and suggests that large deviation analysis would serve as a powerful method to investigate thermalization in the presence of the large finite-size effect.

description: Totally about 110 sites will be selected in the Upper Mississippi Embayment. Broadband station will be installed at each site. Also P- and S-wave seismic reflection/refraction profile will be conducted at each selected site. Broadband installation will be grouped into 15 sites (or as many as possible) at one time to record local, regional and teleseismic earthquakes for a period from a few days to a few months. Once there are a few earthquakes with good quality of waveforms recorded, they will be relocated to the next 15 stations. Each 15 stations will be deployed as an array to detect mid to lower crust arrivals from local and regional earthquakes.
