X-ray Absorption Spectroscopy of the Multi-phase Interstellar Medium: Oxygen and Neon Abundances

Subjects: subject: Astrophysics (astro-ph)

description: X-ray absorption spectroscopy provides a potentially powerful tool in determining the metal abundances in various phases of the interstellar medium (ISM). We present a case study of the sight line toward 4U 1820-303 (Galactic coordinates l, b=2.79, -7.91 and distance = 7.6 kpc), based on Chandra Grating observations. The detection of OI, OII, OIII, OVII, OVIII, and NeIX Kalpha absorption lines allows us to measure the atomic column densities of the neutral, warm ionized, and hot phases of the ISM through much of the Galactic disk. By comparing these measurements with the 21 cm hydrogen emission and with the pulsar dispersion measure along the same sight line, we estimate the mean oxygen abundances in the neutral and total ionized phases as 0.3(0.2, 0.6) and 2.2(1.1, 3.5) in units of Anders & Grevesse (1989) solar value. This significant oxygen abundance difference is apparently a result of molecule/dust grain destruction and recent metal enrichment in the warm ionized and hot phases. We also measure the column density of neon from its absorption edge and obtain the Ne/O ratio of the neutral plus warm ionized gas as 2.1(1.3, 3.5) solar. Accounting for the expected oxygen contained in molecules and dust grains would reduce the Ne/O ratio by a factor of ~1.5. From a joint-analysis of the OVII, OVIII, and NeIX lines, we obtain the Ne/O abundance ratio of the hot phase as 1.4(0.9, 2.1) solar, which is not sensitive to the exact temperature distribution assumed in the absorption line modeling. These comparable ISM Ne/O ratios for the hot and cooler gas are thus considerably less than the value (2.85+-0.07; 1sigma) recently inferred from corona emission of solar-like stars (Drake & Testa 2005).

description: In this study, we investigate the link between hurricane characteristics, demographics of the Coastal Gulf of Mexico residents, including their household location, and their respective evacuation behavior. Our study is significantly different from the previously made studies on hurricane evacuation behavior in two ways. At first, the research data is collected through recording responses to a series of hypothetical situations which are quite identical to the set of information that people are used to see during the hurricane season. Secondly, this study addresses and includes response heterogeneity while analyzing sample behavior, an issue which has not been addressed in previous research on hurricane evacuation behavior in spite of its importance.

description: We perform a microscopic study on the redistribution of electric charge near the surface of a model $d$-wave superconductor cut along the [110] direction, with a Fermi surface appropriate for cuprate superconductors, using the augmented quasiclassical equations. We identify two possible mechanisms for the redistribution of charged particles different from the well-known magnetic Hall effect, namely; the pair potential gradient (PPG) force due to surface effects on the pair potential and the pressure difference between the normal and superconducting regions arising from the slope of the density of states (SDOS) in the normal states at the Fermi level. Our present results show that in spite of the absence of supercurrents, electric charge is induced around the surface. Moreover, the charging effect due to the SDOS pressure dominates over that due to the PPG force for all the realistic electron-fillings $n=0.8$, $0.9$, and $1.15$, at all temperatures. In addition, for the filling $n=1.15$, the PPG force and the SDOS pressure contributions have the same negative signs, which gives a larger total surface charge i.e., both the sign and amount of the surface charge depends greatly on the Fermi-surface curvature. We have also calculated the local density of states (LDOS) within the augmented quasiclassical theory. Spatially varying local particle-hole asymmetry appears in the LDOS, which suggests the presence of electric charge.

description: This paper examines the impact of biofuel expansion on grain utilization and distribution at the state and cropping district level as most of grain producers and handlers are directly influenced by the local changes. We conducted a survey to understand the utilization and flows of corn, ethanol and its co-products, such as dried distillers grains (DDG) in Iowa. Results suggest that the rapidly expanding ethanol industry has a significant impact on corn utilization in Iowa. Comparing to the earlier survey results, ethanol plants drew a considerable amount of corn away from traditional destination markets, such as feeders or export markets. A major portion of corn supplies came from in-state sources, while the sales of Iowa ethanol and DDG were dominated by out-of-state buyers.

description: We propose our solution to a particular practical problem in the domain of vehicle routing and scheduling. The generic task is finding the best allocation of the minimum number of \emph{mobile resources} that can provide periodical services in remote locations. These \emph{mobile resources} are based at a single central location. Specifications have been defined initially for a real-life application that is the starting point of an ongoing project. Particularly, the goal is to mitigate health problems in rural areas around a city in Romania. Medically equipped vans are programmed to start daily routes from county capital, provide a given number of examinations in townships within the county and return to the capital city in the same day. From the health care perspective, each van is equipped with an ultrasound scanner, and they are scheduled to investigate pregnant woman each trimester aiming to diagnose potential problems. The project is motivated by reports currently ranking Romania as the country with the highest infant mortality rate in the European Union. We developed our solution in two phases: modeling of the most relevant parameters and data available for our goal and then design and implement an algorithm that provides an optimized solution. The most important metric of an output scheduling is the number of vans that are necessary to provide a given amount of examination time per township, followed by total travel time or fuel consumption, number of different routes, and others. Our solution implements two probabilistic algorithms out of which we chose the one that performs the best.

description: This paper estimates a demand system for a selected tropical fresh fruit and vegetable imports in to the U.S. using a Linear Approximate Almost Ideal Demand Systems model for the period 1989-2008. Further the paper attempts to capture trade policy and seasonality effects that affect the demand for fresh fruit and vegetable imports. Results show that most of the price elasticities of demand have the expected signs and less than unity magnitude except for tomatoes. Complimentary commodities include bananas and papayas, grapes, and mangoes, peppers and tomatoes and avocados, and tomatoes and cucumber. Substitutes include pineapples and papayas, grapes and papayas, and mangoes and tomatoes. Trade policy and seasonality are also found to affect fresh fruit and vegetable imports.

description: Cosmic crystallography is based on the principle that peaks in the pair separation histogram (PSH) of objects in a catalogue should be induced by the high number of topologically lensed pairs that are separated by Clifford translations, in excess to ``random'' pairs of objects. Here we present modifications of this method that successively improve the signal-to-noise ratio by removing a large part of the noise and then false signals induced by selection effects. Given the transient nature of the most readily available tracer objects, active galactic nuclei (AGNs), the former is possible because a natural filter for removing many of the noise pairs is available: when counting pairs of objects in order to create PSHs, only those with nearly identical redshifts need to be counted. This redshift filter (a maximum value of $Δz/z = 0.005$) was applied to a compilation of AGN catalogues. Further noise was removed by applying a second filter, a maximum angle $Δθ=0.075$ rad, and a minimum number of pairs $\protect\npairs=3$ to find each ``bunch of pairs'' (BoP) where the {\em vectors} (in Euclidean comoving space) defined by pairs are required to be nearly equal, whereas in the PSH only the {\em lengths} must be nearly equal. These filters reveal significant signals, which, however, are due to selection effects. A third filter, a minimum length $\Lselec=150$ {\hMpc} between the (parallel) vectors in a BoP, is found to effectively remove these selection effect pairs. After application of these successive filters, no significant topological signal was found.

title: The role of cultural beliefs in shaping farmers' behavioural decisions to adapt to drought risks in Gaza Province - Southern Mozambique
Creators: name: Salite, Daniela Lidia Jacob
Publisher: name: University of Reading
Year: 2019

description: Drought has had an adverse effect on farmers' agricultural activities, livestock production, health and livelihoods. Therefore, adaptation of the agricultural sector is urgent to reduce farmers' vulnerability, enhance their resilience and adapt to drought. Several factors have affected farmers' adaptation to drought, such as socio-economic, technical, institutional and cultural. However, this study aims to explore the under-researched role of cultural beliefs in shaping these farmers' behavioural decisions to adapt to drought. To undertake this, the study takes the case of small-scale rain-fed farmers in the southern province of Gaza, Mozambique. Findings show that farmers have a limited knowledge and understanding of climate change, and lack scientific information about drought. Instead, many farmers believe that drought is a punishment from God or their ancestors for some wrongdoing. Nonetheless, the farmers find a variety of explanations for the wrongdoing, which are based on their value-laden perceptions of morally wrong occurrences that are taking place nationwide. The findings also show that farmers' implement reactive responses to deal with the causes and the impacts of drought. However, farmers' cultural beliefs influence the timing and order of implementation of two types of response. Firstly, farmers usually implement collective responses to correct the perceived wrongdoing, ask for forgiveness and rain from God and/or their ancestors through the medium of traditional ceremonies and prayer. These responses bind farmers together in solidarity in times of drought as they are driven by their common need for rainfall for their agricultural activities. The responses thus act as a psychological support system for farmers in their attempts to deal with the causes of drought, and to recover from the hardship. Secondly, farmers, often on an individual basis, implement diverse strategies to reduce the impacts of drought through activities to generate income, and to secure immediate food needs or help from the government, family and friends. Farmers' choices of these types of responses and their level of vulnerability are not only driven by their cultural practices, but also by the socio-economic and institutional environment in which they live. Although all the above reactive strategies are not yet helping farmers to adapt to drought, results do not demonstrate culture as a barrier to adaptation in the first instance. Rather, the approach with which drought adaptation strategies are designed and implemented is what dictates whether or not culture will constitute a barrier or help. Therefore, the study emphasises the crucial need to understanding farmers' cultural dimensions of adaptation and further incorporate them in the design and implementation of drought adaptation strategies in order to increase farmers' support and engagement with them and the likelihood of a successful adaptive outcome.

description: Most agricultural production results in both marketable and non-marketable products. Most policy decisions however, tend to be made based only on the market value, which ignores the non-marketable value or amenity benefits. One type of amenity benefits is farmland amenities which are attributes of farmland that are uniquely provided by actively farmed land. Examples include the scenic beauty of rolling pasture, orchards and the cultural value of farming as a way of life. Farmland also produces non-farm amenities, such as open space, wildlife habitats, and groundwater recharge. Most amenity benefits are classified as public goods in that they are non-excludable and non-rival in terms of use. Thus, most amenities do not have a market value associated with them so that their value can not be captured by landowners and therefore are subject to market failure. This failure leads to government intervention in an effort to encourage and support agriculture with programs for farmers through various public policies. Failure to include amenity benefits results in under-allocation of resources like land towards pecan production.

description: We report here the Chandra ACIS-S detection of a bright soft X-ray transient in the Mira AB interacting symbiotic-like binary. We resolved the system for the first time in the X-rays. Using Chandra and HST images we determined that the unprecedented outburst is likely associated with the cool AGB star (Mira A), the prototype of Mira-type variables. X-rays have never before been detected from an AGB star, and the recent activity signals that the system is undergoing dramatic changes. The total X-ray luminosity of the system is several times higher than the luminosity estimated using previous XMM and ROSAT observations. The outburst may be caused by a giant flare in Mira A associated with a mass ejection or a jet, and may have long term consequences on the system.

description: Minimally invasive experimental methods that can measure local rate dependent mechanical properties are essential in understanding the behaviour of soft and biological materials in a wide range of applications. Needle based measurement techniques such as Cavitation Rheology and Volume Controlled Cavity Expansion (VCCE), allow for minimally invasive local mechanical testing, but have been limited to measuring the elastic material properties. Here, we propose several enhancements to the VCCE technique to adapt it for characterization of viscoelastic response at low to medium stretch rates ($10^{-2}$ - $1$ s${}^{-1}$). The proposed technique performs several cycles of expansion-relaxation at controlled stretch rates in a cavity expansion setting and then employs a large deformation viscoelastic model to capture the measured material response. Application of the technique to soft PDMS rubber reveals significant rate dependent material response with high precision and repeatability, while isolating equilibrated states that are used to directly infer the quasistatic elastic modulus. The technique is further established by demonstrating its ability to capture changes in the rate dependent material response of a tuneable PDMS system. The measured viscoelastic properties are used to explain earlier reports of rate insensitive material response by needle based methods: it is demonstrated that the conventional use of constant volumetric rate cavity expansion can induce high stretch rates that lead to viscoelastic stiffening and an illusion of rate insensitive material response. We thus conclude with a cautionary note on possible overestimation of the quasistatic elastic modulus in previous studies and suggest that the stretch rate controlled expansion protocol, proposed in this work, is essential for accurate estimation of both quasistatic and dynamic material parameters.

description: This study seeks to forecast land use change in a North Georgia ecosystem, and estimate the economic value of the ecosystem using benefit transfer techniques. We forecast land use change based on a structural time series model and a simple growth rate model. The study suggests a lower bound willingness to pay value of about USD 16,000 per year to ensure compliance with fishing and drinking water quality standards with regard to fecal coliform bacteria and dissolved oxygen. Conservation efforts are likely to cost less than the cost of defensive behavior or ecosystem restoration.

description: Complex geometry and symplectic geometry are mirrors in string theory. The recently developed generalised complex geometry interpolates between the two of them. On the other hand, the classical and quantum mechanics of a finite number of degrees of freedom are respectively described by a symplectic structure and a complex structure on classical phase space. In this letter we analyse the role played by generalised complex geometry in the classical and quantum mechanics of a finite number of degrees of freedom. We identify generalised complex geometry as an appropriate geometrical setup for dualities. The latter are interpreted as transformations connecting points in the interior of the Planck cone with points in the exterior, and viceversa. The Planck cone bears some resemblance with the relativistic light-cone. However the latter cannot be traversed by physical particles, while dualities do connect the region outside the Planck cone with the region inside, and viceversa.

Namely the spiral arm of a galaxy located at z=0.89 on the line of sight to the radio-loud quasar PKS 1830-211. OCS, SO2, and NH2CN were also detected, raising the total number of molecular species identified in that early time galaxy to 54, not counting isotopologues. The detections were made in absorption against the SW quasar image, at 2 kpc from the galaxy centre, over the course of a Q band spectral line survey made with the Yebes 40 m telescope (rest-frame frequencies: 58.7-93.5 GHz). We derived the rotational temperatures and column densities of those species, which are found to be subthermally excited. The molecular abundances, and in particular the large abundances of C3H+ and of several previously reported cations, are characteristic of diffuse or translucent clouds with enhanced UV radiation or strong shocks.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We study gauge theories on the world-volume of D3-branes probing singularities. Seiberg duality can be realized as a sequence of Picard-Lefschetz monodromies on 3-cycles in the mirror manifold. In previous work, the precise meaning of gauge theories obtained by monodromies that do not correspond to Seiberg duality was unclear. Recently, it was pointed out that these theories contain tachyons, suggesting that the collection of marginally bound branes at the singularity is unstable. We address this problem using (p,q) web techniques. It is shown that theories with tachyons appear whenever the (p,q) web contains crossing legs. A recent study of these theories with tachyons using exceptional collections proposed the notion of "well split condition.'' We show the equivalence between the well split condition and the absence of crossing legs in the (p,q) web. The (p,q) web has a natural resolution of crossing legs which was first studied in the construction of five dimensional fixed points using branes. Exploiting this result, we propose a generic procedure which determines the quiver that corresponds to the stable bound state of D-branes that live on the singularity after the monodromy. This set is generically larger than the original set, meaning that there are extra massless gauge fields and matter fields in the quiver. Alternatively, one can argue that since these gauge and matter fields are initially assumed to be absent, the theory exhibits tachyonic excitations. We illustrate our ideas in an explicit example for D3-branes on a complex cone over dP1, computing both the quiver and the superpotential.

description: There have been significant changes in consumer demand at the retail counter, such as health, convenience, palatability preferences, and safety concerns. Branded programs offer a means for satisfying consumer demand for high quality and differentiated beef products. To help answer the question of who is purchasing branded beef market and why, an online survey was sent to interested beef consumers to determine their preferences of purchasing, as well as values they attribute to certain product characteristics. The total sample response from 13,000 contacted consumers was 502 responses, which according to Kreiche and Morgan, 1970 is a valid sample size. Decision variables ranked moderate and always important include guaranteed tender and satisfaction, low price, and low fat or lean. Differences in the strength of the decision values, such as always important, moderately important to seldom important were found with gender, purchasing frequency product differences. Results provide a better understanding of consumer decisions to buy branded beef and may assist producers with advertising decisions.

We find that for clean systems, the low-bias low-temperature conductance, G, of an armchair edge system in quantized as G/t=4 n e^2/h, whereas for a zig-zag edge the quantization changes to G/t t=4(n+1/2)e^2/h, where t is the transmission probability and n is an integer. We also study the effects of a non-zero bias, temperature, and magnetic field on the conductance. The magnetic field dependence of the quantization plateaus in these systems is somewhat different from the one found in the two-dimensional electron gas due to a different Landau level quantization.

Fists, youth, and protest : Oshima Nagisa’s filmic rebellion in 1960
Creators: name: Shepherdson, Kari L.
Publisher: name: University of British Columbia
Year: 2009

description: In 1960, as the heated protests against the renewal of the U.S.-Japan Security Treaty raged on the streets of Tokyo, Japanese director, Oshima Nagisa, produced three films: “Cruel Story of Youth”, “Graveyard of the Sun”, and “Night and Fog in Japan”. Privileging tales of angry, young rebels, lashing out at oppressive social, economic, and political forces, the films seemed to capture the frustrated feelings of the protesting students on the streets in front of the Diet. Oshima revealed the inspiration the momentous protests (known as the Ampo Struggle) had upon him and his filmic production by referring directly to the protests and the angry demonstrators. However, I argue his films were neither simple antiauthoritarian youth films nor solely concerned with the party politics of the Ampo struggle. Rather, I will explore the ways in which Oshima's films intersect with the several layers of Japanese history and point to the director's pessimism towards the repeated ideological defeat Japanese generations in Japan. I will discuss in this paper the ways in which Oshima sought out the adolescent audience to existentially challenge them to find meaning within themselves by actively critiquing those systems which worked to define their existence: (American) materialism, violence and crime, and participation in left-wing protest politics. I argue that through these films, Oshima sought to inspire the young rebels of Japan to rebel in such a way that they would fracture their perpetual, easily betrayed, dependence upon abstract ideals to lend their life meaning. To unwrap the possible message Oshima intended to convey to the youthful audience, I will use Albert Camus' “The Rebel: An Essay on Man in Revolt”. Camus' text and the controversy among the existential elite in France after its release help to read Oshima's filmic juxtaposition of protests and personal rebellion.

description: Affective brain-computer interfaces are a relatively new area of research in affective computing. Estimation of affective states can improve human-computer interaction as well as improve the care of people with severe disabilities. To assess the effectiveness of EEG recordings in recognizing affective state, here we used data collected in our lab as well as the publicly available DEAP database. We also reviewed the articles that used the DEAP database and found that a significant number of articles did not consider the presence of the class imbalance in the DEAP. Failing to consider class imbalance creates misleading results. Further, ignoring class imbalance makes the comparing results between studies impossible, since different datasets will have different class imbalances. Class imbalance also shifts the chance level, hence it is vital to consider class bias while determining if the results are above chance. To properly account the effect of class imbalance, we suggest the use of balanced accuracy as a performance metric and its posterior distribution for computing credible intervals. For classification, we used features mentioned in the literature and additionally theta beta-1 ratio. Results from DEAP and our data suggest that the beta band power, theta band power, and theta beta-1 ratio are better feature sets for classifying valence, arousal, and dominance, respectively.

description: We investigate the infrared properties of the next-to-leading-order dispersion relations in scalar quantum electrodynamics at high temperature in the context of hard-thermal-loop perturbation theory. Specifically, we determine the damping rate and the energy for scalars with ultrasoft momenta. We show by explicit calculations that an early external-momentum expansion, before the Matsubara sum is performed, gives exactly the same result as a late one. The damping rate is obtained up to fourth order included in the ultrasoft momentum and the energy up to second order. The damping rate is found sensitive in the infrared whereas the energy not.

Exact dynamics of the homogeneous two-qubit $XXZ$ central spin model with the spin bath prepared in superpositions of symmetric Dicke states

description: We obtain exact dynamics of a two-qubit central spin model (CSM) consisting of two interacting qubits homogeneously coupled to a spin bath via the $XXZ$-type coupling, with the bath initially prepared in linear superpositions of the symmetric Dicke states. Using the interaction picture Hamiltonian with respect to the non-spin-flipping part of the model, we derive a sequence of equations of motion within each magnetization sector satisfied by the probability amplitudes of the time-evolved state. These equations of motion admit analytical solutions for the single-qubit CSM in which one of the two central qubits decouples from the rest of the system. Based on this, we provide a quantitative interpretation to the observed collapse-revival phenomena in the single-qubit Rabi oscillations when the bath is prepared in the spin coherent state. We then study the disentanglement and coherence dynamics of two initially entangled noninteracting qubits when the two qubits interact with individual baths or with a common bath. For individual baths the coherent dynamics is found to positively correlated to the single-qubit purity dynamics, and entanglement sudden disappearance and revivals are observed in both cases. The entanglement creation of two initially separable qubits coupled to a common bath is also studied and collapse and revival behaviors in the entanglement dynamics are observed. Choosing the equally weighted state and the $W$-class states as the bath initial states, we finally study the dynamics of entanglement between two individual bath spins and demonstrate the entanglement sharing mechanism in such a system.

description: The effects of the soft gluon emission in hard scattering processes at the phase boundary are resummed in the soft-collinear effective theory (SCET). In SCET, the soft gluon emission is decoupled from the energetic collinear part, and is obtained by the vacuum expectation value of the soft Wilson-line operator. The form of the soft Wilson lines is universal in deep inelastic scattering, in the Drell-Yan process, in the jet production from e+e- collisions, and in the gamma* gamma* -> pi0 process, but its analytic structure is slightly different in each process. The anomalous dimensions of the soft Wilson-line operators for these processes are computed along the light-like path at leading order in SCET and to first order in alpha_s, and the renormalization group behavior of the soft Wilson lines is discussed.
