description: Semi-analytical methods, based on Eulerian perturbation theory, are a promising tool to follow the time evolution of cosmological perturbations at small redshifts and at mildly nonlinear scales. All these schemes are based on two approximations: the existence of a smoothing scale and the single-stream approximation, where velocity dispersion of the dark matter fluid, as well as higher moments of the particle distributions, are neglected. Despite being widely recognized, these two assumptions are, in principle, incompatible, since any finite smoothing scale gives rise to velocity dispersion and higher moments at larger scales. We describe a new approach to perturbation theory, where the Vlasov and fluid equations are derived in presence of a finite coarse-graining scale: this allows a clear separation between long and short distance modes and leads to a hybrid approach where the former are treated perturbatively and the effect of the latter is encoded in external source terms for velocity, velocity dispersion, and all the higher order moments, which can be computed from N-body simulations. We apply the coarse-grained perturbation theory to the computation of the power spectrum and the cross-spectrum between density and velocity dispersion, and compare the results with N-body simulations, finding good agreement.

description: Our results concern geometry of a manifold endowed with a pair of complementary orthogonal distributions (plane fields) and a time-dependent Riemannian metric. The work begins with formulae concerning deformations of geometric quantities as the Riemannian metric varies conformally along one of the distributions. Then we introduce the Extrinsic Geometric Flow depending on the mean curvature vector field of the distribution, and show existence/uniquenes and convergence of a solution as $t\to\infty$, when the complementary distribution is integrable with compact leaves. We apply the method to the problem of prescribing mean curvature vector field of a foliation, and give examples for harmonic and umbilical foliations and for the double-twisted product metrics, including the codimension-one case.

description: We have used the VIMOS integral field spectrograph to map the emission line properties in a sample of 24 star forming galaxies selected from the SDSS database. In this data paper we present and describe the sample, and explore some basic properties of SDSS galaxies with resolved emission line fields. We fit the Halpha+[NII] emission lines in each spectrum to derive maps of continuum, Halpha flux, velocity and velocity dispersion. The Halpha, Hbeta, [NII] and [OIII] emission lines are also fit in summed spectra for circular annuli of increasing radius. A simple mass model is used to estimate dynamical mass within 10 kpc, which compared to estimates of stellar mass shows that between 10 and 100% of total mass is in stars. We present plots showing the radial behaviour of EW[Halpha], u-i colour and emission line ratios. Although EW[Halpha] and u-i colour trace current or recent star formation, the radial profiles are often quite different. Whilst line ratios do vary with annular radius, radial gradients in galaxies with central line ratios typical of AGN or LINERS are mild, with a hard component of ionization required out to large radii. We use our VIMOS maps to quantify the fraction of Halpha emission contained within the SDSS fibre, taking the ratio of total Halpha flux to that of a simulated SDSS fibre. A comparison of the flux ratios to colour-based SDSS extrapolations shows a 175% dispersion in the ratio of estimated to actual corrections in normal star forming galaxies, with larger errors in galaxies containing AGN. We find a strong correlation between indicators of nuclear activity: galaxies with AGN-like line ratios and/or radio emission frequently show enhanced dispersion peaks in their cores, requiring non-thermal sources of heating. Altogether, about half of the galaxies in our sample show no evidence for nuclear activity or non-thermal heating.

Dilaton dominance relaxes LHC and cosmological constraints in supersymmetric models

description: It has been pointed out recently that the presence of dilaton field in the early Universe can dilute the neutralino dark matter (DM) abundance, if Universe is not radiation dominated at DM decoupling, due to its dissipative-like coupling to DM. In this scenario two basic mechanisms compete, the modified Hubble expansion rate tending to increase the relic density and a dissipative force that tends to decrease it. The net effect can lead to an overall dramatic decrease of the predicted relic abundance, sometimes by amounts of the order of O(10^2) or so. This feature is rather generic, independent of any particular assumption on the underlying string dynamics, provided dilaton dominates at early eras after the end of inflation but before Big Bang Nucleosynthesis (BBN). The latter ensures that BBN is not upset by the presence of the dilaton. In this paper, within the context of such a scenario, we study the phenomenology of the constrained minimal supersymmetric model (CMSSM) by taking into account all recent experimental constraints, including those from the LHC searches. We find that the allowed parameter space is greatly enlarged and includes regions that are beyond the reach of LHC. The allowed regions are compatible with Direct Dark Matter searches since the small neutralino annihilation rates, that are now in accord with the cosmological data on the relic density, imply small neutralino-nucleon cross sections below the sensitivities of the Direct Dark Matter experiments. It is also important that the new cosmologically accepted regions are compatible with Higgs boson masses larger than 120 GeV, as it is indicated from the LHC experimental data. The smaller annihilation cross sections needed to explain WMAP data require that the detector performances of current and planned indirect DM search experiments through gamma rays should be greatly improved in order to probe the CMSSM regions.

description: Quality Rating Improvement Systems (QRIS) are now operating state-wide in 18 states. An additional 13 states are implementing QRIS in selected regions or as pilot initiatives. While highly varied in their specific features, these systems all use a set of interrelated strategies that aim to raise the quality of early care and education programs. These strategies include quality standards that programs must meet to obtain ratings at different levels, financial incentives for programs to meet quality standards, and assistance to help center-based programs and homebased providers improve the quality of supports for children's well-being and early learning. As these systems increase in number across the states, ongoing examination of their characteristics and impacts can inform efforts to strengthen them. This report presents findings from an interview study that investigated features of the professional development and on-site assistance available to center-based staff and home-based providers who participate in states' Quality Rating Improvement Systems.

description: We consider a generalization of the Hopfield model, where the entries of patterns are Gaussian and diluted. We focus on the high-storage regime and we investigate analytically the topological properties of the emergent network, as well as the thermodynamic properties of the model. We find that, by properly tuning the dilution in the pattern entries, the network can recover different topological regimes characterized by peculiar scalings of the average coordination number with respect to the system size. The structure is also shown to exhibit a large degree of cliquishness, even when very sparse. Moreover, we obtain explicitly the replica symmetric free energy and the self-consistency equations for the overlaps (order parameters of the theory), which turn out to be classical weighted sums of 'sub-overlaps' defined on all possible sub-graphs. Finally, a study of criticality is performed through a small-overlap expansion of the self-consistencies and through a whole fluctuation theory developed for their rescaled correlations: Both approaches show that the net effect of dilution in pattern entries is to rescale the critical noise level at which ergodicity breaks down.

description: Recent work has shown that different theoretical approaches to the dynamics of the Susceptible-Infected-Susceptible (SIS) model for epidemics lead to qualitatively different estimates for the position of the epidemic threshold in networks. Here we present large-scale numerical simulations of the SIS dynamics on various types of networks, allowing the precise determination of the effective threshold for systems of finite size N. We compare quantitatively the numerical thresholds with theoretical predictions of the heterogeneous mean-field theory and of the quenched mean-field theory. We show that the latter is in general more accurate, scaling with N with the correct exponent, but often failing to capture the correct prefactor.

Scoping Review Protocol

description: Introduction: Tick surveillance is important to detect new ticks or changes in tick occurrence and distribution within a region. This facilitates communication of and response to changes in tick distribution. Tick surveillance systems also provide a framework from which to assess tick-borne disease carriage. This information can be used to launch further investigation and inform risk assessments and mitigation strategies for tick-borne disease in people and animals. For example, many tick surveillance systems focus on blacklegged ticks, like Ixodes scapularis, that can carry Borrelia burgdorferi, the causative agent of Lyme disease. Lyme disease can cause clinical signs such as erythema migrans, meningitis, cranial neuropathy, arthritis, carditis (1 ) in people and some animal species like dogs and horses. White-footed mice and other small mammals are important natural reservoirs of the bacteria while deer and other mammals can carry the ticks (2,3). Hard ticks (Family: Ixodidae) are found in an increasingly broad range of environments as climate change apparently makes it possible for them to survive in regions where they had not previously been found (4). Lyme disease, and other tick-borne diseases such as Rocky Mountain spotted fever and Anaplasmosis, are a One Health problem, at the interface between human health, animal health, and the environment. Objectives: The primary objective of this scoping review is to describe the characteristics of tick surveillance systems from 1960 onward. This research will focus on reviewing published and grey literature and then describing the characteristics of tick surveillance systems, including location, year, type of surveillance, and method of data collection. Methods: This scoping review will be carried out following PRISMA guidelines for scoping reviews. Databases used include MEDLINE, CAB Abstracts, BIOSIS Previews and the Web of Science Core Collection. ProQuest Dissertations will be searched for relevant dissertations. The articles will be screened at the title and abstract, and full text levels by two reviewers blinded to each other's assessment. Articles published prior to 1960 will be excluded, and only articles that describe surveillance systems will be included. Government websites will also be searched for information about tick surveillance programs, globally.

description: With more than four billion usage of cellular phones worldwide, mobile advertising has become an attractive alternative to online advertisements. In this paper, we propose a new targeted advertising policy for Wireless Service Providers (WSPs) via SMS or MMS- namely {\em AdCell}. In our model, a WSP charges the advertisers for showing their ads. Each advertiser has a valuation for specific types of customers in various times and locations and has a limit on the maximum available budget. Each query is in the form of time and location and is associated with one individual customer. In order to achieve a non-intrusive delivery, only a limited number of ads can be sent to each customer. Recently, new services have been introduced that offer location-based advertising over cellular network that fit in our model (e.g., ShopAlerts by AT&T) . We consider both online and offline version of the AdCell problem and develop approximation algorithms with constant competitive ratio. For the online version, we assume that the appearances of the queries follow a stochastic distribution and thus consider a Bayesian setting. Furthermore, queries may come from different distributions on different times. This model generalizes several previous advertising models such as online secretary problem \cite{HKP04}, online bipartite matching \cite{KVV90,FMMM09} and AdWords \cite{saberi05}. ...

The resulting divisions caused an enduring realignment of Australian politics and left Australian society deeply fractured along sectarian lines and between those who had volunteered for service - the superior citizen - and those who had not.

Unveiling Uncertainty and Complexity in Inland Fisheries

description: Inland fisheries are valuable from social, ecological, and economic perspectives, but data collected by resource management agencies are typically observational in nature and hence difficult to learn from (i.e., such data rarely originate from well-designed experiments). Thus, a central challenge facing inland fisheries ecology and management is the extraction of reliable information from observational data. The goal of this dissertation was to show that ecological knowledge and understanding in inland fisheries are dependent on the methods used and the assumptions made when learning from applied observational data, and that in general there is more uncertainty and complexity present in these systems than has been previously acknowledged. To demonstrate this claim, tactical modeling tools that probe systems for uncertainties were applied to help inform a set of fisheries management problems in Alberta, Canada. Chapter 2 developed Bayesian capture-recapture models to demonstrate that abundance of Rainbow Trout in the lower Bow River likely declined during 2003-2013, but the available data offered no insights into the causal factor(s) responsible for this decline. Chapter 3 evaluated whether angler concerns about slow-growing Walleye were caused by high densities of conspecifics in lakes. This chapter showed that spatial-temporal growth models outperformed simpler models when simulated data featured spatial-temporal correlation. Applying these models to the Alberta Walleye data then showed that Walleye growth rates did not decline with increasing density of conspecifics, and that growth rate was unrelated to several predictors believed to influence it. Chapter 4 fitted age-structured population dynamics models to data from a landscape-scale monitoring program to assess Walleye population status and reconstruct recruitment dynamics following the collapse of these fisheries during the 1990s. This chapter showed that recovery from collapse was driven by favorable recruitment events during 1998-2002 in 33/55 lakes and that 9/55 lakes featured cyclic recruitment dynamics. Collectively, this work demonstrates the considerable challenges associated with analyzing inland fisheries data, which has broad implications for ecologists and managers seeking to extract reliable information from similar applied datasets.

description: We propose to measure the radii of the Penn State - Torun Planet Search (PTPS) exoplanet host star candidates using the CHARA Array. Stellar radii estimated from spectroscopic analysis are usually inaccurate due to indirect nature of the method and strong evolutionary model dependency. Also the so-called degeneracy of stellar evolutionary tracks due to convergence of many tracks in the giant branch decreases the precision of such estimates. However, the radius of a star is a critical parameter for the calculation of stellar luminosity and mass, which are often not well known especially for giants. With well determined effective temperature (from spectroscopy) and radius the luminosity may be calculated precisely. In turn also stellar mass may be estimated much more precisely. Therefore, direct radii measurements increase precision in the determination of planetary candidates masses and the surface temperatures of the planets.

One of the main erosions that has occurred is connected to the Catalan pro-independence bid, with illiberal traits like the disdain for the law and the Courts. The illiberal approach to democracy will be highlighted. The national government is also to be blamed for some reforms affecting the General Council for the Judiciary and for the attempts to undermine and capture counter-majoritarian institutions, designed to control and counterbalance political power.

description: A chemical investigation of Solanum lyratum Thumb. (Solanace) afforded two new lignans (1b and 3) and eleven known lignan analogues (1a, 2a/2b and 4–11). Compounds 1a/1b and 2a/2b were separated as two pairs of enantiomers by chiral high-performance liquid chromatography (HPLC). Their structures were elucidated by detailed spectroscopic and comparative literature data analysis. The absolute configurations of compounds 1a/1b and 2a/2b were determined by comparing the experimental ECD data with the calculated values. All compounds were evaluated for their acetylcholinesterase (AChE) inhibitory activity. Notably, compared to the positive control, compounds 4 and 9 showed obvious AChE inhibition with their IC50 values of 1.30 ± 0.25 and 0.89 ± 0.04 μM, respectively. In addition, the possible interaction between acetylcholinesterase and the active compounds was also investigated by molecular docking.

It also analyses the impact of the war in Spain until the immediate post-war period – unequal economic growth, social mobilisation, and political crisis. Primary and secondary sources lead us to conclude that Spain had to maintain neutrality: the matter was simply non-negotiable. However, the final crisis of Spain’s political system was the result of the previously unseen social and ideological mobilisation.

Novel direct redox fuel cell : membraneless low precious metal catalyst electrode assembly
Creators: name: Dara, Mohammad Saad
Publisher: name: University of British Columbia
Year: 2012

description: The direct fuel redox fuel cell (DFRFC) substitutes the oxygen reduction cathode of low temperature fuel cells such as polymer electrolyte membrane fuel cells (PEMFC) and direct methanol fuel cells (DMFC) with an iron redox cathode of a redox flow battery. This approach helps address many of the issues with low temperature fuel cells. For both the PEMFC and DMFC the iron redox cathode eliminates precious metal content from the cathode. With respect to the PEMFC the inherent liquid nature of the iron redox cathode provides both heat and water management to the system which significantly reduces the balance-of-plant components. On the other hand, the issues of fuel crossover for the DMFC are no longer a concern as methanol is not electrochemically active at the carbon cathode used for the ferric reduction reaction. However, the use of metal redox ions in conjunction with a membrane of the same polarity introduces issues of membrane contamination which significantly reduce membrane conductivity resulting in increased ohmic overpotentials and losses in fuel cell performance. In addition, crossover of the redox catholyte can result in anode depolarization. In this a work a novel membraneless direct liquid redox fuel cell is demonstrated. The membraneless design utilizes 3-D electrode(s), the engineering of which allows control of the reactant concentration gradients. This control of the reactant gradient allows for more complete reactant utilization which mitigate catholyte crossover and allow for the elimination of the PEM. The PEM in the DFRFC used in this work is replaced with an open-spacer and liquid acid electrolyte. In addition, this novel membraneless electrode assembly design is completely scalable and flexible to different platforms, fuels, oxidants and electrolytes. In this work a membraneless direct hydrogen redox fuel cell and membraneless direct methanol redox fuel cell based on the 3-D electrode concept and controlled concentration gradient are demonstrated. In addition, the use of the liquid acid electrolyte in the membraneless direct hydrogen redox fuel cell allowed for improved ionic conductivity to the anode catalyst layer. This allowed for significant reductions in precious metal catalyst content to be made from the hydrogen oxidation anode.

description: This brief presents promising approaches to support the social-emotional wellbeing of infants and toddlers through the Part C Program. The strategies discussed in this brief were identified through case studies carried out in four communities: Boston, Massachusetts; Los Angeles County, California; Doña Ana County, New Mexico; and Southeast Kansas. These case studies were part of a larger project designed to show different policy options that states use to support strategies that target social-emotional development as part of a comprehensive approach to early intervention services. The project included a 50-state survey of Part C Program coordinators, the individuals who are responsible for administering the Part C Program in compliance with federal and state requirements. Findings from this survey are reported in Promoting Social-Emotional Wellbeing in Early Intervention Services: A Fifty State View. As a companion to the survey report, this brief examines exemplary policies and practices that highlight the potential of the Part C Early Intervention Program to play a major role in reducing the risk of long-term social-emotional and behavioral difficulties of vulnerable children.
