description: The obscuring circumnuclear torus of dusty molecular gas is one of the major components of active galactic nuclei (AGN). The torus can be studied by analyzing the time response of its infrared (IR) dust emission to variations in the AGN continuum luminosity, a technique known as reverberation mapping. The IR response is the convolution of the AGN ultraviolet/optical light curve with a transfer function that contains information about the size, geometry, and structure of the torus. Here, we describe a new computer model that simulates the reverberation response of a clumpy torus. Given an input optical light curve, the code computes the emission of a 3D ensemble of dust clouds as a function of time at selected IR wavelengths, taking into account light travel delays. We present simulated dust emission responses at 3.6, 4.5, and 30 $μ$m that explore the effects of various geometrical and structural properties, dust cloud orientation, and anisotropy of the illuminating radiation field. We also briefly explore the effects of cloud shadowing (clouds are shielded from the AGN continuum source). Example synthetic light curves have also been generated, using the observed optical light curve of the Seyfert 1 galaxy NGC 6418 as the input. The torus response is strongly wavelength-dependent, due to the gradient in cloud surface temperature within the torus, and because the cloud emission is strongly anisotropic at shorter wavelengths. Anisotropic illumination of the torus also significantly modifies the torus response, reducing the lag between the IR and optical variations.

description: Quantum correlations between two free spinless dissipative distinguishable particles (interacting with a thermal bath) are studied analytically using the quantum master equation and tools of quantum information. Bath-induced coherence and correlations in an infinite-dimensional Hilbert space are shown. We show that for temperature T > 0 the time-evolution of the reduced density matrix cannot be written as the direct product of two independent particles. We have found a time-scale that characterizes the time when the bath-induced coherence is maximum before being wiped out by dissipation (purity, relative entropy, spatial dispersion, and mirror correlations are studied). The Wigner function associated to the Wannier lattice (where the dissipative quantum walks move) is studied as an indirect measure of the induced correlations among particles. We have supported the quantum character of the correlations by analyzing the geometric quantum discord.

description: In order to investigate the formation mechanisms of the rare compact elliptical galaxies (cE) we have compiled a sample of 25 cEs with good SDSS spectra, covering a range of stellar masses, sizes and environments. They have been visually classified according to the interaction with their host, representing different evolutionary stages. We have included clearly disrupted galaxies, galaxies that despite not showing signs of interaction are located close to a massive neighbor (thus are good candidates for a stripping process), and cEs with no host nearby. For the latter, tidal stripping is less likely to have happened and instead they could simply represent the very low-mass, faint end of the ellipticals. We study a set of properties (structural parameters, stellar populations, star formation histories and mass ratios) that can be used to discriminate between an intrinsic or stripped origin. We find that one diagnostic tool alone is inconclusive for the majority of objects. However, if we combine all the tools a clear picture emerges. The most plausible origin, as well as the evolutionary stage and progenitor type, can be then determined. Our results favor the stripping mechanism for those galaxies in groups and clusters that have a plausible host nearby, but favors an intrinsic origin for those rare cEs without a plausible host and that are located in looser environments.

description: The growth of magnetic films with ferromagnetic interactions between nearest-neighbor spins is studied in $(d+1)-$dimensional rectangular geometries for $d = 1,2$. Magnetic films are grown irreversibly by adding spins at the boundaries of the growing interface. The orientation of the added spins depends on both the energetic interaction with already deposited spins and the temperature, through a Boltzmann factor. At low temperatures thin films, of thickness $L$, are constituted by a sequence of well ordered magnetic domains. Spins belonging to each domain, of average length $l_{D} \gg L$, have mostly the same orientation, but consecutive domains have opposite magnetization. Such kind of ``spontaneous magnetization reversal'' during the growth process has a short characteristic length $l_{R}$, such that $l_{D} \gg l_{R} \sim L$. At higher temperatures, a transition between ordered and disordered states is also observed. The emerging behavior is compared to that of the equilibrium Ising model.

description: En el presente estudio nos proponemos el examen del poemario Trilce de César Vallejo, así como la aplicación metodológica de algunos principios de la pragmática literaria para su análisis. El primer aspecto es motivado por la importancia que esta obra poética reviste, no sólo para la literatura latinoamericana del siglo XX, sino también porque, derivado de su configuración artística y los alcances existenciales de su expresión, la obra se ha situado como una de las voces más altas de la poesía en lengua española. Con relación al segundo aspecto, hemos de referir que debido a su hermetismo (casi dos terceras partes son poemas complejos), consideramos que un enfoque pragmático de la literatura cuya finalidad es el examen del emisor, del texto, del receptor y los contextos, es teórica y metodológicamente apropiado para estudiar una obra con las particulares que definen a Trilce.

description: Water resources are crucial for sustainable development, and their effective management is essential (Guldal and Tongal, 2010). Given the spatio-temporal variability of rainfall, it is imperative to focus on flood and drought management. River discharge prediction is vital for mitigating the risks associated with these hazards, enabling both structural and non-structural measures to be implemented. Accurate rainfall-discharge modeling is valuable for optimizing water utilization, enhancing flood forecasts, and facilitating drought management. Various models have been suggested to understand the rainfall-runoff dynamics within a watershed's fluvial system (Agarwal et al. 2006). These models fall into distinct categories such as physical, conceptual, stochastic, and data-driven models (Senaviratne et al. 2014). Data-driven models like Artificial Neural Network (ANN), Adaptive Neuro-Fuzzy Inference System (ANFIS) etc. demonstrate real-time capabilities in predicting hydrological phenomena.

description: Pesticides are organic substances which are purportedly designed to increase agricultural yield, soil productivity, product quality while minimising the pest- mediated crop losses, and controlling insect vectors in order to halt the spread of epidemics in both humans and animals.  An increase in the use of pesticides and herbicides has been noticed in the recent decades in the agriculture and food sector. More than 500 of chemical compounds have been registered and utilised as pesticides or pesticide metabolites globally. Among South Asian countries in terms of total pesticide consumption, India is the greatest pesticide consumer, accounting for 3% of global crop protection consumption.

description: We use 2H NMR stimulated-echo spectroscopy to measure two-time correlation functions characterizing the polymer segmental motion in polymer electrolytes PPO-LiClO4 near the glass transition temperature Tg. To investigate effects of the salt on the polymer dynamics, we compare results for different ether oxygen to lithium ratios, namely, 6:1, 15:1, 30:1 and infinity. For all compositions, we find nonexponential correlation functions, which can be described by a Kohlrausch function. The mean correlation times show quantitatively that an increase of the salt concentration results in a strong slowing down of the segmental motion. Consistently, for the high 6:1 salt concentration, a high apparent activation energy E_a=4.1eV characterizes the temperature dependence of the mean correlation times at Tg < T< 1.1T_g, while smaller values E_a=2.5eV are observed for moderate salt contents. The correlation functions are most nonexponential for 15:1 PPO-LiClO4, whereas the stretching is reduced for higher and lower salt concentrations. A similar dependence of the correlation functions on the evolution time in the presence and in the absence of ions indicates that addition of salt hardly affects the reorientational mechanism. For all compositions, mean jump angles of about 15 degree characterize the segmental reorientation. In addition, comparison of results from 2H and 7Li NMR stimulated-echo experiments suggests a coupling of ion and polymer dynamics in 15:1 PPO-LiClO4.

description: A case study is presented on the relation between interflow travel time and reservoir stratification. A simulation model is calibrated and validated for the Wachusett Reservoir in Massachusetts. The Reservoir has a major controlled inflow which traverses the reservoir as an interflow. The model is used with a range of alternate inflow schedules and the resulting travel time of the interflow is examined. The inflow density is within the range of densities found in the reservoir thermocline and the inflow rate is sufficient to maintain a continuous interflow. Under these conditions it is found that a linear relation exists between the average interflow travel time, as measured by the arrival of a specified fraction of interflow water at the outlet, and the degree of stratification, as measured by the maximum difference in reservoir thermocline temperature, at the initiation of the inflow. The results may be useful for operation of the reservoir under study subject to continued validation of the simulation model used.

description: Anyons are exotic quasi-particles with fractional charge that can emerge as fundamental excitations of strongly interacting topological quantum phases of matter. Unlike ordinary fermions and bosons, they may obey non-abelian statistics--a property that would help realize fault tolerant quantum computation. Non-abelian anyons have long been predicted to occur in the fractional quantum Hall (FQH) phases that form in two-dimensional electron gases (2DEG) in the presence of a large magnetic field, su ch as the $ν=\tfrac{5}{2}$ FQH state. However, direct experimental evidence of anyons and tests that can distinguish between abelian and non-abelian quantum ground states with such excitations have remained elusive. Here we propose a new experimental approach to directly visualize the structure of interacting electronic states of FQH states with the scanning tunneling microscope (STM). Our theoretical calculations show how spectroscopy mapping with the STM near individual impurity defects can be used to image fractional statistics in FQH states, identifying unique signatures in such measurements that can distinguish different proposed ground states. The presence of locally trapped anyons should leave distinct signatures in STM spectroscopic maps, and enables a new approach to directly detect - and perhaps ultimately manipulate - these exotic quasi-particles.

description: The phase structure of Nambu-Jona-Lasinio model with N-component fermions in curved space-time is studied in the leading order of the 1/N expansion. The effective potential for composite operator $\barψψ$ is calculated by using the normal coordinate expansion in the Schwinger proper-time method. The existence of the first-order phase transition caused by the change of the space-time curvature is confirmed and the dynamical mass of the fermion is calculated as a simultaneous function of the curvature and the four-fermion coupling constant. The phase diagram in the curvature and the coupling constant is obtained.

description: A wind nebula generating extended X-ray emission was recently detected surrounding Swift 1834.9-0846. This is the first magnetar for which such a (pulsar) wind nebula (PWN) was found. I demonstrate that Swift 1834.9-0846's nebula can be rotationally-powered if it is being compressed by the environment. The physical reason behind this is the dominance of adiabatic heating over all other cooling and escape processes. This effect can happen only for pulsars of relatively low spin-down power and can make for very efficient nebulae. This contribution is based on previous work published in ApJ 835, article id. 54, 13 pp. (2017).

description: GaN/SiO2 core/shell nanowires are grown by cobalt phthalocyanine catalyst assisted vapor-liquid-solid route, in which Si wafer coated with a mixture of gallium and indium is used as the source for Ga and Si and ammonia is used as the precursor for nitrogen and hydrogen. Gallium in the presence of indium and hydrogen, which results from the dissociation of ammonia, forms Si-Ga-In alloy at the growth temperature around 910 degree Celsius. This alloy acts as the source of Si, Ga and In. A detailed study using a variety of characterization tools reveals that these wires, which are several tens of micron long, has a diameter distribution of the core ranging from 20 to 50 nm, while the thickness of the amorphous SiO2 shell layer is about 10 nm. These wires grow along direction. It has also been observed that the average width of these wires decreases, while their density increases as the gallium proportion in the Ga-In mixture is increased.

description: We calculate the star formation quenching timescales in green valley galaxies at intermediate redshifts ($z\sim0.5-1$) using stacked zCOSMOS spectra of different galaxy morphological types: spheroidal, disk-like, irregular and merger, dividing disk-like galaxies further into unbarred, weakly-barred and strongly-barred, assuming a simple exponentially-decaying star formation history model and based on the H$_δ$ absorption feature and the $4000$ Å~break. We find that different morphological types present different star formation quenching timescales, reinforcing the idea that the galaxy morphology is strongly correlated with the physical processes responsible for quenching star formation. Our quantification of the star formation quenching timescale indicates that disks have typical timescales $60\%$ to 5 times longer than that of galaxies presenting spheroidal, irregular or merger morphologies. Barred galaxies in particular present the slowest transition timescales through the green valley. This suggests that although secular evolution may ultimately lead to gas exhaustion in the host galaxy via bar-induced gas inflows that trigger star formation activity, secular agents are not major contributors in the rapid quenching of galaxies at these redshifts. Galaxy interaction, associated with the elliptical, irregular and merger morphologies contribute, to a more significant degree, to the fast transition through the green valley at these redshifts. In the light of previous works suggesting that both secular and merger processes are responsible for the star formation quenching at low redshifts, our results provide an explanation to the recent findings that star formation quenching happened at a faster pace at $z\sim0.8$.

In this work we study the result of proportional elections using an opinion dynamics model similar to simple opinion spreading over a complex network. Erdos-Renyi, Barabasi-Albert, regular lattices and randomly augmented lattices are considered as models of the underlying social networks. The model reproduces the power law behavior of number of candidates with a given number of votes found in real elections with the correct slope, a cutoff for larger number of votes and a plateau for small number of votes. It is found that the small world property of the underlying network is fundamental for the emergence of the power law regime.

description: We present results from observations of the most famous starburst galaxy M82 with the High-Resolution Camera onboard the Chandra X-Ray Observatory. We found nine sources in the central 1' x 1' region, but no source was detected at the galactic center. Comparing the observations on 1999 October 28 and on 2000 January 20, we found four of the nine sources showed significant time variability. In particular, CXOM82J095550.2+694047, which is 9" away from the galactic center, showed extremely large time variability. We conclude that this source is the origin of the hard X-ray time variability of M82 detected with ASCA. Assuming a spectral shape obtained by the ASCA observation, its luminosity in the 0.5 -- 10 keV band changed from 1.2E40 erg/s on 1999 October 28 to 8.7E40 erg/s on 2000 January 20.

Rediscovering Community Participation in Persian Qanats: An Actor-Network Framework
Creators: name: Salek, Arash
Publisher: name: European Journal of Creative Practices in Cities and Landscapes

Subjects: qanats; participatory water management; social ecosystem; Actor-Network Theory

description: Most of Iran's inland areas have permanently lain within arid regions. Today, Iran’s groundwater depletion-rate today among the fastest in the world. From the beginning of the agricultural revolution and land-reform in the 1960s, Iran has adopted a governmental highly bureaucratic approach to water management fuelled by technological improvements in high water-dam constructions and modernization of irrigation infrastructure. However, these systems relied on the centralized water management which couldn’t solve the issue of the country’s increasing water-stresses and therefore it has been challenged by many critiques from civil society and academia. For centuries, Iran has relied on socio-economic networks to manage groundwater and the traditional method of water-exploitation named qanats which represents an effective system of social corporation and civic participation in water management and in solving the issue of water scarcity in dry regions. This paper introduces a theoretical framework for the necessary transition from the centralized water management towards a multi-actor water-governance regime by adapting the Actor-Network Theory for understanding the traditional patterns of collective water management inside qanat-dependent communities.

description: Water accessibility in Israel and the Palestinian Territories is part of the politics in the Israeli-Palestinian conflict and contributes to the feeling of mistrust and misunderstanding between Israelis and Palestinians. This article explores the implications of access to water. It proposes an architectural design for a Temple of Water as a catalyst for dialogue and understanding between Israelis and Palestinians in the water-stressed region of Hebron on the southern West Bank. It aims to create a water space for social and communal practices as a vehicle for social interaction. Opportunities for peaceful coexistence are needed in conflict areas. The Temple of Water makes a statement about water’s power, meaning and influence. The research highlights the potential of spatial planning and design to promote either conflict or peaceful coexistence. Key specifications for architectural projects in water-stressed and conflict-ridden spaces have been defined with a theoretical framework concerning the value and implications of water in Israel and Palestine. The research takes a step towards understanding the power, meaning and influence that water can have through its physical embodiment in an architectural artefact.

description: A persistent spin helix (PSH) in spin-orbit-coupled two-dimensional electron systems was recently predicted to exist in two cases: [001] quantum wells (QWs) with equal coupling strengths of the Rashba and the Dresselhaus interactions (RD), and Dresselhaus-only [110] QWs. Here we present supporting results and further investigations, using our previous results [Phys. Rev. B 72, 153305 (2005)]. Refined PSH patterns for both RD [001] and Dresselhaus [110] QWs are shown, such that the feature of the helix is clearly seen. We also discuss the time dependence of spin to reexamine the origin of the predicted persistence of the PSH. For the RD [001] case, we further take into account the random Rashba effect, which is much more realistic than the constant Rashba model. The distorted PSH pattern thus obtained suggests that such a PSH may be more observable in the Dresselhaus [110] QWs, if the dopants cannot be regularly enough distributed.

Policies enabling resilience in Seattle's water services

Subjects: water supply; wastewater; stormwater; water services management; water resilience

description: The combined impact of diverse transitions, such as climate change, population growth, rapid urbanization and ageing infrastructure are expected to affect the quantity, quality, accessibility and affordability of water globally. Water demand and competition for water are likely to increase. Addressing these changes and hazards requires societies to be resilient, i.e. flexible and adaptive instead of only resistant. Seattle, Washington USA, has a long history of sustainable development and adaptation to changes and hazards such as population growth, water pollution, droughts and floods. Based on a literature review and semi-structured interviews among twelve selected local water professionals, this paper a) defines development steps and policies that have led to the current situation; b) explores key policies that are important to the resilience of Seattle’s water services; and c) examines challenges in and recommendations for improving resilience in the future. The results reveal the importance of specific policies and practices in enabling resilience for each water service: water supply, wastewater and stormwater. They also reveal governance levels where resilience is most powerfully implemented. The paper concludes that policies that were found to build and improve the resilience of Seattle’s water services are diverse and most effective when implemented at a local level. In advancing resilience, it is important to acknowledge also informal rules, including mindsets and habits.

Subjects: water heritage; displacement; riverfront development; UNESCO World Heritage

description: In 2002, the city of Ahmedabad (India) was profoundly shaken by severe interreligious riots. Subsequent years saw deep transformations in the image of the city and the consolidation of the right-wing Hindu nationalist party in the local and supra-local political arena. This article investigates some of the spatial manifestations of an urban transformation involving the valorization of historical heritage. The article focuses in particular on the large-scale Sabarmati Riverfront Development Project, which began in 2005 and remains ongoing, and on the inclusion of the historical center of Ahmedabad in the World Heritage List in 2017. The two developments have profoundly reshaped the image of the city and its river. The article offers an analysis of the city's transformations and of the related rhetoric promoted by the local governing coalition. It highlights the city's role in shaping a vision of a global, sustainable and historic metropolis.

description: Recently there has been remarkable progress in solving the sign problem, which occurs in investigating statistical systems with a complex weight. The two promising methods, the complex Langevin method and the Lefschetz thimble method, share the idea of complexifying the dynamical variables, but their relationship has not been clear. Here we propose a unified formulation, in which the sign problem is taken care of by both the Langevin dynamics and the holomorphic gradient flow. We apply our formulation to a simple model in three different ways and show that one of them interpolates the two methods by changing the flow time.

description: We investigate the phase diagram of QCD-like gauge theories at strong coupling at finite magnetic field $B$, temperature $T$ and baryon chemical potential $μ$ using the improved holographic QCD model including the full backreaction of the quarks in the plasma. In addition to the phase diagram we study the behavior of the quark condensate as a function of $T$, $B$ and $μ$ and discuss the fate of (inverse) magnetic catalysis at finite $μ$. In particular we observe that inverse magnetic catalysis exists only for small values of the baryon chemical potential. The speed of sound in this holographic quark-gluon plasma exhibits interesting dependence on the thermodynamic parameters.

Solitons in Bose-Einstein Condensates with Helicoidal Spin-Orbit Coupling

description: We report on the existence and stability of freely moving solitons in a spatially inhomogeneous Bose- Einstein condensate with helicoidal spin-orbit (SO) coupling. In spite of the periodically varying parameters, the system allows for the existence of stable propagating solitons. Such states are found in the rotating frame, where the helicoidal SO coupling is reduced to a homogeneous one. In the absence of the Zeeman splitting, the coupled Gross-Pitaevskii equations describing localized states feature many properties of the integrable systems. In particular, four-parametric families of solitons can be obtained in the exact form. Such solitons interact elastically. Zeeman splitting still allows for the existence of two families of moving solitons, but makes collisions of solitons inelastic.
