The Unusual AGN Host NGC 1266: Evidence for Shocks in a Molecular Gas Rich S0 Galaxy with a Low Luminosity Nucleus

description: NGC 1266 is a lenticular galaxy (S0) hosting an active galactic nucleus (AGN), and known to contain a large amount of shocked gas. We compare the luminosity ratio of mid-\emph{J} CO lines to IR continuum with star-forming galaxies (SFGs), and then model the CO spectral line energy distribution (SLED). We confirm that in the mid- and high-\emph{J} regions ($J_{\rm up}$ = 4--13), the C-type shock ($v_{\rm s}$ = 25 km s$^{-1}$, $n_{\rm H}$ = $5\times10^{4}$ cm$^{-3}$) can reproduce the CO observations well. The galaxy spectral energy distribution (SED) is constructed and modeled by the code {\tt X-CIGALE} and obtains a set of physical parameters including the star formation rate (SFR, 1.17 $\pm$ 0.47 \emph{M$_{\odot}$}yr$^{-1}$). Also, our work provides SFR derivation of [C\,{\sc ii}] from the neutral hydrogen regions only (1.38 $\pm$ 0.14 $M_{\odot}$yr$^{-1}$). Previous studies have illusive conclusions on the AGN or starburst nature of the NGC 1266 nucleus. Our SED model shows that the hidden AGN in the system is intrinsically low-luminosity, consequently the infrared luminosity of the AGN does not reach the expected level. Archival data from \emph{NuSTAR} hard X-ray observations in the 3--79 keV band shows a marginal detection, disfavoring presence of an obscured luminous AGN and implying that a compact starburst is more likely dominant for the NGC 1266 nucleus.

description: Mitochondria evolved from the ancestral bacterial endosymbiont whose genes were either integrated into the host nucleus or lost, this gave rise to a novel protein import system in mitochondria. Reclinomonas americana is a unicellular eukaryote and has the most gene-rich mitochondrial genome known. The mitochondrial genome of R. americana encodes a bacterial-like protein transport subunit, SecY, and many mitochondrial-encoded gene products have predicted topologies or signal sequences that would be compatible for SecY-mediated protein export. One such mitochondrial-encoded gene of R. americana, RaCox11, was utilized to examine whether it could be transferred into the nucleus. Biochemical analyses of RaCox11 showed that it could functionally complement a Δcox11 yeast mutant when expressed in the cytosol. This predisposed mitochondrial targeting ability of proteins is one of the underlying possibilities of why many proteins secreted from pathogenic bacteria are also frequently targeted to mitochondria during infection. Many bacterial effector proteins are found frequently targeted to mitochondria during infection, but the import routes into mitochondria are mostly unknown. In this study, the mitochondrial targeting pathways of two pathogenic bacterial proteins, LncP and PVL, have been characterized to be transported by the Tim9:10 chaperone complex at the intermembrane space of mitochondria. From the intermembrane space, they are guided to and assembled into the inner membrane of mitochondria. With the precise localization and targeting pathways of these pathogenic proteins now known, it opens up the possibility to investigate their roles in the modulation of mitochondrial function during bacterial infections.

description: La investigación estuvo orientada a desarrollar un análisis comparativo en relación a la viabilidad técnica y económica en la implementación de sistemas de vivienda de interés social vertical Vs. horizontal en la ciudad de Cartagena, , que permita el aprovechamiento óptimo del suelo utilizable para V.I.S, disminuyendo así los índices de generación de suelo urbano para dicho fin. Para ello se establecieron cuatro etapas claves que permitieron avanzar en tal sentido y llegar a los resultados propuestos. En este sentido se procedió a realizar una caracterización socioeconómica de la población cartagenera perteneciente a estratos I y II teniendo en cuenta el orden de sus gustos y preferencias hacia la adquisición de VIS y los diferentes atributos y beneficios que estas ofrecen, mediante la aplicación de un cuestionario de quince (15) preguntas a una muestra representativa de 399 personas. Seguidamente, se definieron las características estructurales, arquitectónicas y constructivas para las viviendas de interés social tipo horizontal y vertical. Así mismo, se realizó un análisis comparativo, planteando las ventajas y desventajas que presentan las viviendas de interés social de tipo vertical y horizontal, desde el punto de vista técnico y económico. Para ello se tomó como referencia base al macroproyecto Ciudad del Bicentenario de la ciudad de Cartagena, ya que este brindaba una propuesta que reunía todos los atributos a evaluar, ahorrando con ello un tiempo de ejecución muy valioso. Finalmente se definieron y propusieron posibles zonas ordenación urbanística que ofrecieran los requerimientos mínimos e idóneos para construir viviendas de Interés Social de tipo vertical en la ciudad de Cartagena. Por el lado de las conclusiones se obtuvo que la densificación de las ciudades permite el aprovechamiento del territorio dentro del tejido urbano, planteando que su crecimiento sea de manera vertical. Ahora bien, desde el punto de vista económico vale la pena resaltar que entre la vivienda de tipo vertical y horizontal, no existen diferencias significativas en el costo del metro cuadrado construido, aunque resulta curioso que a la hora de lograr una mayor integración y consenso de intereses de los diferentes actores involucrados (gobierno nacional, proveedores, constructores y usuarios), es el tipo de vivienda vertical quien ofrece los mayores rendimientos o beneficios, en los que tiene que ver con un mayor aprovechamiento del terreno, al punto que este puede maximizarse mucho más que las soluciones vivienda horizontal por metro cuadrado

description: Long-wavelength matter inhomogeneities contain cleaner information on the nature of primordial perturbations as well as the physics of the early universe. The large-scale coherent overdensity and tidal force, not directly observable for a finite-volume galaxy survey, are both related to the Hessian of large-scale gravitational potential and therefore of equal importance. We show that the coherent tidal force causes a homogeneous anisotropic distortion of the observed distribution of galaxies in all three directions, perpendicular and parallel to the line-of-sight direction. This effect mimics the redshift-space distortion signal of galaxy peculiar velocities, as well as a distortion by the Alcock-Paczynski effect. We quantify its impact on the redshift-space power spectrum to the leading order, and discuss its importance for the ongoing and upcoming galaxy surveys.

description: Elastic scattering angular distribution for weakly bound nucleus $^{6}$Li on the deformed rare earth $^{159}$Tb target nucleus has been measured at energies around the Coulomb barrier. The elastic scattering cross sections for this reaction consist of inelastic contributions from low lying excited states of $^{159}$Tb. The pure elastic cross-sections have been extracted from the admixture of elastic and inelastic data. The optical model potential parameters for the system have been obtained from the extracted pure elastic scattering cross sections. Coupled channel calculations have been performed with this set of potential parameters, to compare the theoretical and experimental inelastic scattering cross sections. The work has been extended to obtain the spectroscopic factor for $^{158}$Tb+n configuration from the experimental 1n-pickup data.

description: Los procesos físicos y químicos modelados e investigados a través de prototipos usualmente son más fáciles de seguir cuando la tarea de recolección de datos es simplificada por algún sistema de toma de datos en el mismo, lo anterior toma mucha más importancia en procesos complejos de implementar y/o monitorizar como el de la ósmosis. Por lo anterior, se formuló el presente con el objetivo realizado de establecer un sistema de recolección de datos para el prototipo que opera bajo procesos de Ósmosis Inversa y Ósmosis por Presión Retardada del programa de Ingeniería de Civil de la Universidad de Cartagena en su semillero adscrito GIMA usando Hardware libre, C++ como lenguaje para el sistema embebido y tecnologías y lenguajes programación frecuentemente utilizados para desarrollos de aplicaciones web en tiempo real (MongoDB, NodeJS, React), usando los protocolos necesarios para las conexiones con los sensores y las pantalla en el sistema embebido desde el microcontrolador; además, del uso de un protocolo de conexión por paquetes ligeros para MQTT en la conexión del sistema embebido y el sistema remoto. Lo que infiere que como producto final se llegó a la realización de dos sistemas una plataforma para la recepción de los datos (ubicado en el VPS del servidor del semillero SEMARD) y el desarrollo de un sistema embebido de recolección de datos, que al ser analizados permite concluir que, aunque la Open Hardware permite crear un sistema de recolección de datos adecuado dadas las presiones encontradas en el proceso osmótico y la alta sensibilidad de la lectura de la variación de masa durante el proceso, la optimización de este requiere de mucha parametrización (que puede tomar mucho tiempo) razón por la que se tiende a elegir la tecnología propietaria para agilizar desarrollos.

description: We report new frequency-comb-based measurements of Ca Rydberg energy levels. Counter-propagating laser beams at 390 nm and 423 nm excite Ca atoms from the $4s^2~^1\mbox{S}_0$ ground state to $4sns~^1\mbox{S}_0$ Rydberg levels with $n$ ranging from 40 to 110. Near-resonant two-photon two-color excitation of atoms in a thermal beam makes it possible to eliminate the first-order Doppler shift. The resulting lineshapes are symmetric and Gaussian. We verify laser metrology and absolute accuracy by reproducing measurements of well-known transitions in Cs, close to the fundamental wavelengths of our frequency-doubled ti:sapphire lasers. From the measured transition energies we derive the ionization potential of Ca, $E_{\rm IP} = 1, 478, 154, 283.42 \pm 0.08 \mbox{(statistical)} \pm 0.07 \mbox{(systematic)}$ MHz, improving the previous best determination by a factor of 11.

description: Observational studies have widely demonstrated that galaxy physical properties are strongly affected by the surrounding environment. On one side, gas inflows provide galaxies with new fuel for star formation. On the other side, the high temperatures and densities of the medium are expected to induce quenching in the star formation. Observations of large structures, in particular filaments at the cluster outskirts (r>2r$_{200}$), are currently limited to the low redshift Universe. We present a multi-band dataset for the cluster MACS J0416.1-2403 (z=0.397), observed in the context of the Galaxy Assembly as a function of Mass and Environment with VST (VST-GAME) survey. The project aims at gathering deep ($r$<24.4) and wide (20x20Mpc$^2$) observations at optical wavelengths for six massive galaxy clusters at 0.2

High-Threshold Low-Overhead Fault-Tolerant Classical Computation and the Replacement of Measurements with Unitary Quantum Gates

description: Von Neumann's classic "multiplexing" method is unique in achieving high-threshold fault-tolerant classical computation (FTCC), but has several significant barriers to implementation: i) the extremely complex circuits required by randomized connections, ii) the difficulty of calculating its performance in practical regimes of both code size and logical error rate, and iii) the (perceived) need for large code sizes. Here we present numerical results indicating that the third assertion is false, and introduce a novel scheme that eliminates the two remaining problems while retaining a threshold very close to von Neumann's ideal of 1/6. We present a simple, highly ordered wiring structure that vastly reduces the circuit complexity, demonstrates that randomization is unnecessary, and provides a feasible method to calculate the performance. This in turn allows us to show that the scheme requires only moderate code sizes, vastly outperforms concatenation schemes, and under a standard error model a unitary implementation realizes universal FTCC with an accuracy threshold of p < 5.5%, in which p is the error probability for 3-qubit gates. FTCC is a key component in realizing measurement-free protocols for quantum information processing. In view of this we use our scheme to show that all-unitary quantum circuits can reproduce any measurement-based feedback process in which the asymptotic error probabilities for the measurement and feedback are 0.51p and 1.51p, respectively.

description: The reliable characterization of planetary atmospheres with transmission spectroscopy requires realistic modeling of stellar magnetic features, since features that are attributable to an exoplanet atmosphere could instead stem from the host star's magnetic activity. Current retrieval algorithms for analysing transmission spectra rely on intensity contrasts of magnetic features from 1D radiative-convective models. However, magnetic features, especially faculae, are not fully captured by such simplified models. Here we investigate how well such 1D models can reproduce 3D facular contrasts, taking a G2V star as an example. We employ the well established radiative magnetohydrodynamic code MURaM to obtain three-dimensional simulations of the magneto-convection and photosphere harboring a local small-scale-dynamo. Simulations without additional vertical magnetic fields are taken to describe the quiet solar regions, while simulations with initially 100 G, 200 G and 300 G vertical magnetic fields are used to represent different magnetic activity levels. Subsequently, the spectra emergent from the MURaM cubes are calculated with the MPS-ATLAS radiative transfer code. We find that the wavelength dependence of facular contrast from 1D radiative-convective models cannot reproduce facular contrasts obtained from 3D modeling. This has far reaching consequences for exoplanet characterization using transmission spectroscopy, where accurate knowledge of the host star is essential for unbiased inferences of the planetary atmospheric properties.

CFD Modeling and Simulation on Hydrodynamics of CFB Biomass Gasifier using FLUENT

description: Biomass gasification in Circulating fluidized beds (CFB) is one of the most promising conversion processes in meeting future ecologically compatible and sustainable energy demand, based on a combination of flexibility, efficiency, and environmental acceptability. Widespread industrial use of CFB technology in coal and biomass combustion and gasification depends on improved control of the fluidization process that demands a better understanding of fluidized bed hydrodynamics. However, its application to CFB systems is limited due to the high computational requirements for understanding complex fluid flow behavior. The effect of different operating parameters on the hydrodynamic behavior of a two-phase gas-solid CFB biomass gasifier were studied in this thesis work systematically using computational fluid dynamics (CFD) software FLUENT. Both 2-D and 3-D computational fluid dynamics (CFD) model based on Eulerian-Eulerian approach coupled with granular kinetic theory is developed to simulate the hydrodynamics and flow structures of the CFB under different operating conditions. A parametric analysis is performed to comprehensively investigate the influences of particle properties (Bagasse, sand and its sizes), operating parameters (gas velocity and solid circulation rate) and gasifier geometries (inlet structure/position). The dynamic characteristics obtained from CFD simulation have been compare ed with the some similar conditions experimental data obtained from open literatures and in general a good agreement has been observed. Eulerian-Eulerian granular multiphase flow model approach is capable of predicting the core-annulus structure in CFB. The lower region of the CFB riser is denser than the upper-dilute region. Back-mixing behavior or accumulation of particles near the wall has been perfectly exist in the CFB. Increasing solids flux slows down the flow development, but increasing superficial gas velocity makes the flow development faster. Superficial gas velocity has a strong influence on the axial solids velocity. The volume fraction of big particles is lower in the upper. This hydrodynamics model provides the powerful theoretical basis for next steps on CFB designs. This study proposes that the operating parameters (solid circulation rate and gas velocity) and solid inlet geometry may be the critical consideration in order to reduce non-uniform distribution of gas and solid in CFB gasifier.

description: Inspired by the center-vortex dominance in the infrared sector of $SU(N)$ Yang-Mills theory observed on the lattice, we propose a vacuum wave functional localized on an ensemble of correlated center vortices endowed with stiffness and magnetic monopoles that change the orientation of the vortex flux. In the electric-field representation, this wave functional becomes an effective partition function for N complex scalar fields. The inclusion of both oriented and non-oriented vortices as well as so-called N-vortex matchings leads to an effective potential that has only a center symmetry left. In the center-vortex condensed phase, this symmetry is spontaneously broken. In this case, the Wilson loop average can be approximated by a solitonic saddle-point localized around the minimal surface. The asymptotic string tension thus obtained displays Casimir scaling.

description: The Fermi surface of elemental bismuth consists of three small rotationally equivalent electron pockets, offering a valley degree of freedom to charge carriers. A relatively small magnetic field can confine electrons to their lowest Landau level. This is the quantum limit attained in other dilute metals upon application of sufficiently strong magnetic field. Here, we report on the observation of another threshold magnetic field never encountered before in any other solid. Above this field, $B_{\rm{empty}}$, one or two valleys become totally empty. Drying up a Fermi sea by magnetic field in the Brillouin zone leads to a manyfold enhancement in electric conductance. We trace the origin of the large drop in magnetoresistance across $B_{\rm{empty}}$ to transfer of carriers between valleys with highly anisotropic mobilities. The non-interacting picture of electrons with field-dependent mobility explains most results. Coulomb interaction may play a role in shaping the fine details.

description: In this paper an equation means a homogeneous linear partial differential equation in $n$ unknown functions of $m$ variables which has real or complex polynomial coefficients. The solution set consists of all $n$-tuples of real or complex analytic functions that satisfy the equation. For a given system of equations we would like to characterize its Weyl closure, i.e. the set of all equations that vanish on the solution set of the given system. It is well-known that in many special cases the Weyl closure is equal to $B_m(F)N \cap A_m(F)^n$ where $F$ is either the field of real or complex numbers, $A_m(F)$ (respectively $B_m(F)$) consists of all linear partial differential operators with coefficients in $F[x_1,\ldots,x_m]$ (respectively $F(x_1,\ldots,x_m)$) and $N$ is the submodule of $A_m(F)^n$ generated by the given system. Our main result is that this formula holds in general. In particular, we do not assume that the module $A_m(F)^n/N$ has finite rank which used to be a standard assumption. Our approach works also for the real case which was not possible with previous methods. Moreover, our proof is constructive as it depends only on the Riquier-Janet theory.

description: Current sheets are spatially localized almost-1D structures with intense plasma currents. They play a key role in storing the magnetic field energy and they separate different plasma populations in planetary magnetospheres, the solar wind, and the solar corona. Current sheets are primary regions for the magnetic field line reconnection responsible for plasma heating and charged particle acceleration. One of the most interesting and widely observed type of 1D current sheets is the rotational discontinuity, that can be force-free or include plasma compression. Theoretical models of such 1D current sheets are based on the assumption of adiabatic motion of ions, i.e. ion adiabatic invariants are conserved. We focus on three current sheet configurations, widely observed in the Earth magnetopause and magnetotail and in the near-Earth solar wind. Magnetic field in such current sheets is supported by currents carried by transient ions, which exist only when there is a sufficient number of invariants. In this paper, we apply a novel machine learning approach, AI Poincar'e, to determine parametrical domains where adiabatic invariants are conserved. For all three current sheet configurations, these domains are quite narrow and do not cover the entire parametrical range of observed current sheets. We discuss possible interpretation of obtained results indicating that 1D current sheets are dynamical rather than static plasma equilibria.

description: Event logs, as viewed in process mining, contain event data describing the execution of operational processes. Most process mining techniques take an event log as input and generate insights about the underlying process by analyzing the data provided. Consequently, handling large volumes of event data is essential to apply process mining successfully. Traditionally, individual process executions are considered sequentially ordered process activities. However, process executions are increasingly viewed as partially ordered activities to more accurately reflect process behavior observed in reality, such as simultaneous execution of activities. Process executions comprising partially ordered activities may contain more complex activity patterns than sequence-based process executions. This paper presents a novel query language to call up process executions from event logs containing partially ordered activities. The query language allows users to specify complex ordering relations over activities, i.e., control flow constraints. Evaluating a query for a given log returns process executions satisfying the specified constraints. We demonstrate the implementation of the query language in a process mining tool and evaluate its performance on real-life event logs.

description: Neural population equations such as neural mass or field models are widely used to study brain activity on a large scale. However, the relation of these models to the properties of single neurons is unclear. Here we derive an equation for several interacting populations at the mesoscopic scale starting from a microscopic model of randomly connected generalized integrate-and-fire neuron models. Each population consists of 50 -- 2000 neurons of the same type but different populations account for different neuron types. The stochastic population equations that we find reveal how spike-history effects in single-neuron dynamics such as refractoriness and adaptation interact with finite-size fluctuations on the population level. Efficient integration of the stochastic mesoscopic equations reproduces the statistical behavior of the population activities obtained from microscopic simulations of a full spiking neural network model. The theory describes nonlinear emergent dynamics like finite-size-induced stochastic transitions in multistable networks and synchronization in balanced networks of excitatory and inhibitory neurons. The mesoscopic equations are employed to rapidly simulate a model of a local cortical microcircuit consisting of eight neuron types. Our theory establishes a general framework for modeling finite-size neural population dynamics based on single cell and synapse parameters and offers an efficient approach to analyzing cortical circuits and computations.

Assessment of Corruption Challenges in Executing Construction Projects: The Case of Two Federal Housing Projects in Addis Ababa, Ethiopia
Creators: name: Abreha, Haregot
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2017

description: Now a day's corruption is a hot spot and public issue in any government institution. It became a major concern for economic, social and political development nationally and globally. The effect of corruption in Ethiopia has manifested in different sectors including in the housing projects. It creates project delay, poor quality and overrun cost. Corruption is still a persistent and public complain issue in housing projects especially project run by federal government in Addis Ababa. Therefore, the main purpose of this study was to assess the main corruption challenges (offenses) manifested in housing project. It also conducted to identify the major causes of corruption and the level of effort of different stakeholders in tackling the problem. Based on this aim, data was collected through questionnaire and interview from three stakeholder's cluster groups, 10 institutions and.155 respondents, which was selected, based on purposive sampling method. The data collected was coded, analyzed and interpreted and the result shows that collusion among contractors and consultants, substructure and underground bulk excavation, procurement rigging, bribe for low quality supply etc are the main corruption offenses happened in housing projects. Poor accountability, poor controlling and monitoring system, poor ethical behavior of contractors and consultants etc are identified as the main cause of corruption in housing projects. Consequently, implementing strong accountability, strengthen auditing and controlling system, improving working procedure, giving deep training on ethics and anti corrutption etc are recommended as remedy to solve the problem in housing projects
Role of parasitic interactions and microwave crosstalk in dispersive control of two superconducting artificial atoms

description: In this work we study the role of parasitic interactions and microwave crosstalk in a system of two superconducting artificial atoms interacting via a single-mode coplanar waveguide. Through a general description of the effective dynamics of the atoms, beyond the two-level approximation, we show that the atom selectivity (ability to individually address an atom) is only dependent on the resultant phasor associated to the drives used to control the system. We then exploit the benefits of such a drive-dependent selectivity to describe how the coherent population inversion occurs in the atoms simultaneously, with no interference of residual atom-atom interaction. In this scenario the parasitic interaction works as a resource to fast and high fidelity control, as it gives rise to a new regime of frequencies for the atoms able to suppress effective atom-atom coupling (idling point). To end, we show how an entangling $i$SWAP gate is implemented with fidelity higher than $99\%$, even in presence of parasitic interactions. More than that, we argue that the existence of this interaction can be helpful to speed up the gate performance. Our results open prospects to a new outlook on the real role of such ``undesired" effects in a system of superconducting artificial atoms.

description: Uncovering microstructure evolution mechanisms that accompany the long-term operation of solid oxide fuel cells is a fundamental challenge in designing a more durable energy system for the future. To date, the study of fuel cell stack degradation has focused mainly on electrochemical performance and, more rarely, on averaged microstructural parameters. Here we show an alternative approach in which an evolution of three-dimensional microstructural features is studied using electron tomography coupled with topological data analysis. The latter produces persistent images of microstructure before and after long-term operation of electrodes. Those images unveil a new insight into the degradation process of three involved phases: nickel, pores, and yttrium-stabilized zirconium.
