Étale categories, restriction semigroups, and their operator algebras
Natã Machado, Gilles G. de Castro
We define the full and reduced non-self-adjoint operator algebras associated with étale categories and restriction semigroups, answering a question posed by Kudryavtseva and Lawson…
Nonlinear -Jordan-type derivations on alternative -algebras
Aline Jaqueline de Oliveira Andrade, Gabriela C. Moraes, Ruth Nascimento Ferreira +1
Let be an unital alternative -algebra. Assume that contains a nontrivial symmetric idempotent element which satisfies implies and $xA \cdot…
Connecting field and intensity correlations: the Siegert relation and how to test it
Dilleys Ferreira, Romain Bachelard, William Guerin +2
The Siegert relation relates the electric field and intensity correlations of light, under given assumptions. After a brief history of intensity correlations, we give a derivation…
Mining social media data for biomedical signals and health-related behavior
Rion Brattig Correia, Ian B. Wood, Johan Bollen +1
Social media data has been increasingly used to study biomedical and health-related phenomena. From cohort level discussions of a condition to planetary level analyses of sentiment…
Diagonalization of the Heun-Askey-Wilson operator, Leonard pairs and the algebraic Bethe ansatz
Pascal Baseilhac, Rodrigo A. Pimenta
An operator of Heun-Askey-Wilson type is diagonalized within the framework of the algebraic Bethe ansatz using the theory of Leonard pairs. For different specializations and the ge…
Towards the solution of an integrable spin chain
Rafael I. Nepomechie, Rodrigo A. Pimenta, Ana L. Retore
Two branches of integrable open quantum-group invariant quantum spin chains are known. For one branch (epsilon=0), a complete Bethe ansatz solution has been propose…
Robustness of Dicke subradiance against thermal decoherence
P. Weiss, A. Cipris, M. O. Araújo +2
Subradiance is the cooperative inhibition of the radiation by several emitters coupled to the same electromagnetic modes. It was predicted by Dicke in 1954 and only recently observ…
Hybrid Longitudinal-Transverse Phonon Polaritons
Christopher R. Gubbin, Rodrigo Berté, Michael A. Meeker +6
We demonstrate how to exploit long-cell polytypes of silicon carbide to achieve strong coupling between transverse phonon polaritons and zone folded longitudinal optical phonons. T…
No cataclysmic variables missing: higher merger rate brings into agreement observed and predicted space densities
Diogo Belloni, Matthias R. Schreiber, Mónica Zorotovic +4
The predicted and observed space density of cataclysmic variables (CVs) have been for a long time discrepant by at least an order of magnitude. The standard model of CV evolution p…
The STRong lensing Insights into the Dark Energy Survey (STRIDES) 2016 follow-up campaign. II. New quasar lenses from double component fitting
T. Anguita, P. L. Schechter, N. Kuropatkin +56
We report upon the follow up of 34 candidate lensed quasars found in the Dark Energy Survey using NTT-EFOSC, Magellan-IMACS, KECK-ESI and SOAR-SAMI. These candidates were selected…
Gas accretion in Milky Way-like galaxies: temporal and radial dependencies
Sebastian E. Nuza, Cecilia Scannapieco, Cristina Chiappini +3
One of the fundamental assumptions of chemical evolution models (CEMs) of the Milky Way (MW) and other spirals is that higher gas accretion rates are expected in the past, and in t…
Outflows in the inner kiloparsec of NGC 1566 as revealed by molecular (ALMA) and ionized gas (Gemini-GMOS/IFU) kinematics
R. Slater, C. Finlez, N. M. Nagar +9
We aim to map the distribution and kinematics of molecular and ionized gas in a sample of active galaxies, to quantify the nuclear inflows and outflows. Here, we analyze the nuclea…
Redox potential replica exchange molecular dynamics at constant pH in AMBER: Implementation and validation
Vinicius Wilian D. Cruzeiro, Marcos S. Amaral, Adrian E. Roitberg
Redox processes are important in chemistry, with applications in biomedicine, chemical analysis, among others. As many redox experiments are also performed at a fixed value of pH,…
CANA: A python package for quantifying control and canalization in Boolean Networks
Rion Brattig Correia, Alexander J. Gates, Xuan Wang +1
Logical models offer a simple but powerful means to understand the complex dynamics of biochemical regulation, without the need to estimate kinetic parameters. However, even simple…
City-wide Analysis of Electronic Health Records Reveals Gender and Age Biases in the Administration of Known Drug-Drug Interactions
Rion Brattig Correia, Luciana P. de Araújo, Mauro M. Mattos +1
The occurrence of drug-drug-interactions (DDI) from multiple drug dispensations is a serious problem, both for individuals and health-care systems, since patients with complication…
Subradiance and radiation trapping in cold atoms
Patrizia Weiss, Michelle O. Araújo, Robin Kaiser +1
We experimentally and numerically study the temporal dynamics of light scattered by large clouds of cold atoms after the exciting laser is switched off in the low intensity (linear…
The optical properties of galaxies in the Ophiuchus cluster
Florence Durret, Ken'ichi Wakamatsu, Christophe Adami +2
We investigate the optical properties of Ophiuchus to obtain clues on the formation epoch of this cluster, and compare them to those of the Coma cluster, which is comparable in mas…
Dynamical equivalence, the origin of the Galactic field stellar and binary population, and the initial radius--mass relation of embedded clusters
Diogo Belloni, Pavel Kroupa, Helio J. Rocha-Pinto +1
In order to allow a better understanding of the origin of Galactic field populations, dynamical equivalence of stellar-dynamical systems has been postulated by Kroupa and Belloni e…
The Herschel Bright Sources (HerBS): Sample definition and SCUBA-2 observations
Tom J. L. C. Bakx, S. A. Eales, M. Negrello +20
We present the Herschel Bright Sources (HerBS) sample, a sample of bright, high-redshift Herschel sources detected in the 616.4 square degree H-ATLAS survey. The HerBS sample conta…
On the relation between the mass of Compact Massive Objects and their host galaxies
R. Capuzzo-Dolcetta, I. Tosta e Melo
Supermassive black holes and/or very dense stellar clusters are found in the central regions of galaxies. Nuclear star clusters are present mainly in faint galaxies while upermassi…
The mean star formation rates of unobscured QSOs: searching for evidence of suppressed or enhanced star formation
F. Stanley, D. M. Alexander, C. M. Harrison +15
We investigate the mean star formation rates (SFRs) in the host galaxies of ~3000 optically selected QSOs from the SDSS survey within the Herschel-ATLAS fields, and a radio-luminou…
