Candidate massive galaxies atz ∼ 4 in the Dark Energy Survey

Using stellar population models, we predicted that the Dark Energy Survey (DES) - due to its special combination of area (5000 deg. sq.) and depth ($i = 24.3$) - would be in the position to detect massive ($\gtrsim 10^{11}$ M$_{\odot}$) galaxies at $z \sim 4$. We confront those theoretical calculations with the first $\sim 150$ deg. sq. of DES data reaching nominal depth. From a catalogue containing $\sim 5$ million sources, $\sim26000$ were found to have observed-frame $g-r$ vs $r-i$ colours within the locus predicted for $z \sim 4$ massive galaxies. We further removed contamination by stars and artefacts, obtaining 606 galaxies lining up by the model selection box. We obtained their photometric redshifts and physical properties by fitting model templates spanning a wide range of star formation histories, reddening and redshift. Key to constrain the models is the addition, to the optical DES bands $g$, $r$, $i$, $z$, and $Y$, of near-IR $J$, $H$, $K_{s}$ data from the Vista Hemisphere Survey. We further applied several quality cuts to the fitting results, including goodness of fit and a unimodal redshift probability distribution. We finally select 233 candidates whose photometric redshift probability distribution function peaks around $z\sim4$, have high stellar masses ($\log($M$^{*}$/M$_{\odot})\sim 11.7$ for a Salpeter IMF) and ages around 0.1 Gyr, i.e. formation redshift around 5. These properties match those of the progenitors of the most massive galaxies in the local universe. This is an ideal sample for spectroscopic follow-up to select the fraction of galaxies which is truly at high redshift. These initial results and those at the survey completion, which we shall push to higher redshifts, will set unprecedented constraints on galaxy formation, evolution, and the re-ionisation epoch.
Antioxidant properties of several tropical fruits : A comparative study

Nine tropical fruits were analyzed for total phenol contents, ascorbic acid contents and antioxidant activities. The antioxidant activities were evaluated based on the ability of the fruit extracts to scavenge 1,1-diphenyl-2-picrylhydrazyl (DPPH), reduce iron(III) to iron (II) and to bind to iron(II) ions. The results were compared to those of orange. It was found that guava, papaya and star fruit have higher primary antioxidant potential, as measured by scavenging DPPH and iron(III) reducing assays. Banana, star fruit, water apple, langsat and papaya have higher secondary antioxidant potential as measured by the iron(II) chelating experiment. 2006 Elsevier Ltd. All rights reserved.
“They don´t represent us!” Opportunities for a Social Movement Unionism Strategy in Spain

Our goal is to analyze strategies of union revitalization that have been successful elsewhere and have the potential to become so in Spain. Within these practices, Social Movement Unionism focuses on alliances with other groups to improve unions’ social efficiency. In this article, we address the applicability of the principles of Social Movement Unionism in the specific case of Spain. Given the transformations in the Spanish economy and labour laws tending towards further deregulation, Spanish unions have had to react. The emergence of new social movements such as the Indignados or Mareas Ciudadanas (civic tides) and the declining confidence in unions among the Spanish population, make this approach timely and appropriate.For this article, we will take certain aspects from the trade union revitalization debate and combine them with the main theories on New Social Movements. We will apply these approaches to a specific case study: The viability of cooperation between the largest Spanish trade unions and the recent social movements arising from the Indignados movement. For this purpose, we will primarily use data from secondary sources and transcripts of interviews conducted with unionists and social movement activists. With all these elements taken into consideration, we will conclude by showing the inhibiting and facilitating conditions for the development of a Social Movement Unionism strategy for the referred actors.
Title Robust Optimal Power Flow with Wind Integration Using Conditional Value-at-Risk Permalink

Integrating renewable energy into the power grid requires intelligent risk-aware dispatch accounting for thestochastic availability of renewables. Toward achieving this goal , a robust DC optimal flow problem is developed in the present paper for power systems with a high penetration of wind energy. The optimal dispatch is obtained as the solution to a convex program with a suitable regularizer, which is able to mitigate the potentially high risk of inadequate wind power. The regularizer is constructed based on the energy transactioncost using conditional value-at-risk (CVaR). Bypassing the prohibitive high-dimensional integral, the distribution-free sample average approximation method is efficiently utilized for solving the resulting optimization problem. Case studies are reportedto corroborate the efficacy of the novel model and approach test ed on the IEEE 30-bus benchmark system with real operation data from seven wind farms.
A COMPARISON OF DIFFERENT METHODS TO REMOVE DISSOLVED OXYGEN: APPLICATION TO THE ELECTROCHEMICAL DETERMINATION OF IMIDACLOPRID

This study compares different methods for the removal of oxygen from the solution prior to the chronopotentiometric determination of the insecticide imidacloprid on glassy carbon electrode. The research included the application of the chemical method involving addition of sulfite ion, and the physical method of purging the sample with nitrogen stream, as well as their combination. By comparing analytical signals of imidacloprid, chemical method showed almost the same efficiency as conventional physical method, while the best reproducibility was achieved by applying chemical method with addition of the saturated sodium sulfite solution. The method is very simple and can be applied for deoxygenation of the solution prior to the chronopotentiometric analysis. The application of the chemical deoxygenation significantly shortened duration of the chronopotentiometric analysis of imidacloprid from approximately 15 min to 1 min.
The State of Human-Animal Studies: Solid, at the Margin!

On the occasion of the tenth anniversary of the publication of Society and Animals, we present a set of 14 papers obtained through individual invitations and a general call for papers on the state of HumanAnimal Studies (HAS). For the purposes of this exercise, we dened HAS broadly as the remit of S&A as it has evolved over the 10 years to include empirical investigations and conceptual analyses of humananimal relationships in both the social sciences and the humanities.
AN INTEGRATION TESTING FACILITY FOR THE CERN ACCELERATOR CONTROLS SYSTEM

A major effort has been invested in the design, development, and deployment of the LHC Control System. This large control system is made up of a set of core components and dependencies, which although tested individually, are often not able to be tested together on a system capable of representing the complete control system environment, including hardware. Furthermore this control system is being adapted and applied to CERN's whole accelerator complex, and in particular for the forthcoming renovation of the PS accelerators. To ensure quality is maintained as the system evolves, and toimprove defect prevention, the Controls Group launched a project to provide a dedicated facility for continuous, automated, integration testing of its core components to incorporate into its production process. We describe the project, initial lessons from its application, status, and future directions.
Implementation of optical flow algorithms in FPGA platforms with embedded CPU

This document aims at presenting the work developed in the field of visual motion characterisation. It describes the various existing techniques for the calculation of the Optical Flow parameter in a set of frames. Project decisions are also addressed and detailed information about the implemented hardware core architecture is provided. The implementation results are analysed to support the final conclusions. The subject of visual perception is considerably vast and its characterization is undisputedly complex. It stands for the process of information gathering about the surrounding world, namely object identification, movement calculation, distance and time to contact estimation. The amount of data that is involved in this process is enormous and so the computational effort required to extract measurable data, in a real-time environment. Researchers have broken the problem into separate areas, one of them being the calculation of the Optical Flow in a scene, which is the main subject of this dissertation. Artificial systems employ mathematical techniques to analyse sequences of frames and extract information about the movement that has occurred in a scene. The inconvenient of such techniques lies on the fact that the computational effort required to analyse a full image is too demanding to be implemented making use of conventional computer architectures. Therefore, these systems either try to reduce their vision field (reducing frame size) or risk not being able to cope with real-time requirements. However, dedicated hardware solutions have also been proposed in the meanwhile with alternative and faster architectures. This dissertation explores the later developments of reconfigurable hardware platforms and altogether with the study of less-efficient implementations, presents an efficient architecture of an Optical Flow estimator and a C implemented framework to communicate with the designed IP core.
The Reason and Coping Measures of Employees’ Resistance to Information System

The management of employee resistance is an important aspect of information system implementation, the resistance of employees relates to successfully implement systems or not. In our research, we first defined information system resistance, and analyzed the reasons of systems resistance from systems, organizations, as well as personal perspectives. Based on this, we then propose the appropriate human resources management proposals, eventually matching the various elements in human resources management, improving the success possibility of system implementation.
LOCATION CONDITIONS OF ENERGY-INTENSIVE ENTERPRISES

There is an interdependent relationship between enterprises and the region in which they are located: On the one hand the conditions of this location influence turnover, costs, profits and thus the economic situation of the individual firm. On the other hand the economic situation of the regional firms is an important determinant of regional economic success and the wel-fare of the people living in that region. This happens directly because the firms stabilize re-gional income and employment; but there are also indirect effects running via income and input-output-linkages. Regional economic success and welfare in turn determine the regional tax receipts and the regions’ possibilities for positively influencing the location conditions. These interdependencies give an explanation for the high interest firms, politicians and re-searchers normally have in regional location conditions and their quality. The better a region’s information about these issues, the better its possibilities to promote its location advan
Design and Implementation of Efficient Coding Schemes for Fault Tolerant Parallel Filters

As the complexity of communications and signal processing systems increases, so does the number of blocks or elements that they have. In many cases, some of those elements operate in parallel, performing the same processing on different signals. A typical example of those elements are digital filters. The increase in complexity also poses reliability challenges and creates the need for fault-tolerant implementations. A scheme based on error correction coding has been recently proposed to protect parallel filters. In that scheme, each filter is treated as a bit, and redundant filters that act as parity check bits are introduced to detect and correct errors. In this brief, the idea of applying coding techniques to protect parallel filters is ddressed in a more general way. In articular, it is shown that the fact that filter inputs and outputs are not bits but numbers enables a more efficient protection. This reduces the protection overhead and makes the number of redundant filters independent of the number of parallel filters. The proposed scheme is first described and then illustrated with two case studies. Finally, both the effectiveness in protecting against errors and the cost are evaluated for a field-programmable gate array implementation. Keywords— Error correction codes(ECCs),filters, soft errors
Gaia Data Release 2

Context. Although the Gaia catalogue on its own is a very powerful tool, it is the combination of this high-accuracy archive with other archives that will truly open up amazing possibilities for astronomical research. The advanced interoperation of archives is based on cross-matching, leaving the user with the feeling of working with one single data archive. The data retrieval should work not only across data archives but also across wavelength domains. The first step for a seamless access to the data is the computation of the cross-match between Gaia and external surveys. Aims. We describe the adopted algorithms and results of the pre-computed cross-match of the Gaia Data Release 2 (DR2) catalogue with dense surveys (Pan-STARRS1 DR1, 2MASS, SDSS DR9, GSC 2.3, URAT-1, allWISE, PPMXL, and APASS DR9) and sparse catalogues (HIPPARCOS2, Tycho-2, and RAVE 5). Methods. A new algorithm is developed specifically for sparse catalogues. Improvements and changes with respect to the algorithm adopted for DR1 are described in detail. Results. The outputs of the cross-match are part of the official Gaia DR2 catalogue. The global analysis of the cross-match results is also presented.
Sea-salt particles and the CLAW hypothesis

Environmental context. When proposing that dimethyl sulfide (DMS) releases from phytoplankton had a role in regulating the global climate, the potential parallel influences of sea spray aerosols on climate were largely disregarded. Over the intervening 20 years, scientific studies have clearly demonstrated a substantial role for sea spray particles in modifying cloud properties and influencing global sulfur cycling, diminishing the significance of the DMS-based CLAW mechanism.
EFFECTS OF DIOXINS AND PCBS ON THE HUMAN ORGANISM AND THEIR INFLUENCE ON DEVELOPING TEETH OF CHILDREN VIA MOTHER

Polychlórované dibenzo-p-dioxíny (PCDD), dibenzofurány (PCDF) a bifenyly (PCB) tvoria skupinu stabilných toxických chemických látok, ktoré ovplyvňujú ľudské zdravie a životné prostredie. Tieto halogénderiváty aromatických uhľovodíkov vznikajú pri spaľovaní rôznych druhov odpadu a sú vedľajšími produktmi rôznych priemyselných procesov. V prípade, že tieto organické znečisťujúce látky uniknú do životného prostredia, zotrvávajú v pôde, vode a v atmosfére po celé desaťročia a ešte dlhý čas po skončení ich úniku spôsobujú obavy o zdravie. Dioxíny poškodzujú imunitný systém, nervovú sústavu, endokrinnú sústavu a reprodukčné funkcie a existuje podozrenie, že spôsobujú aj rakovinu. Ich hlavným zdrojom príjmu pre ľudí je potrava. PCDD, PCDF a PCB sú lipofilné zlúčeniny, odolné voči metabolickej degradácii. So stúpajúcou úrovňou potravinového reťazca majú stúpajúcu tendenciu akumulovať a distribuovať sa do tukového tkaniva. Tehotné a dojčiace matky môžu preniesť tieto polutanty transplacentárne a dojčením, pretože materské mlieko je bohaté na tuk. Konzumácia materského mlieka pritom tvorí pre dojčené deti hlavnú cestu dioxínovej expozície. Koncentrácie PCDD, PCDF a PCB v materskom mlieku sú preto indikátormi ich ľudskej expozície a odrážajú tiež ich koncentrácie v tukovom tkanive. Najtoxickejšou zlúčeninou z tejto skupiny látok je 2,3,7,8-tetrachlórdibenzo-p-dioxín (TCDD). Pri dojčení sa všeobecne uznáva fakt, že vyvíjajúcemu sa dieťaťu ponúka materské mlieko výhody vyváženej výživy a pasívnej imunizácie proti mikrobiálnym infekciám, avšak detekcia perzistujúcich environmentálnych polutantov vo vzorkách materského mlieka viedla k obavám, že tieto chemikálie môžu mať škodlivé účinky na zdravie a/alebo vývin dojčených detí. Klinické nálezy naznačujú, že v závislosti od úrovne ich obsahu v životnom prostredí, môžu byť vyvíjajúce sa zuby detí vnímavé na dioxíny a PCB prijaté prostredníctvom materského mlieka. Prenatálna a postnatálna expozícia týmto zlúčeninám môže spôsobovať vznik abnormalít orálnych mäkkých tkanív a poruchy mineralizácie zubov. Pri subjektoch náhodne vystavených ich vysokým dávkam sa zistila zvýšená prevalencia vývojových defektov skloviny a vrodeného výskytu chýbajúcich zubov. Kľúčové slová: dioxíny, účinky dioxínov, toxikokinetika dioxínov, materské mlieko, kontaminácia materského mlieka, vývojové defekty zubov, PCDD, PCDF, PCB
Center for Behavior , Institutions and the Environment CBIE Working Paper Series # CBIE-2018-008 A Network Theory of Hunter-Gatherer Population Distribution

We develop a network theory of population distribution among mobile hunter-gatherers. This theory proposes that, due to the heterogeneity of resources in space and time, foragers create networks of habitats that they access through residential cycling and shared knowledge. The degree of cycling that individuals exhibit in creating networks of habitats, encoded through social relationships, depends on the relative scarcity of resources and fluctuations in those resources. Using a dynamic model of hunter-gatherer population distribution, we illustrate that increases in population density, coupled with shocks to a biophysical or social system, creates a selective environment that favors habitat partitioning and investments in social mechanisms that control the residential cycling of foragers on a landscape. The archaeological record of the Texas Coastal Plain (TCP) provides a starting point to ground our theory. A preliminary analysis of the long-term energy consumption patterns and investments in burials and grave goods on the TCP conforms to the model’s predictions. Our work extends the Ideal Free Distribution the workhorse population distribution model in human behavioral ecology and illustrates a general variance reduction, safe-operating space tradeoff among mobile human foragers that drives social change.
oneliness , eudaimonia , and the human conserved transcriptional esponse to adversity teven

Background: Chronic social adversity activates a conserved transcriptional response to adversity (CTRA) marked by increased expression of pro-inflammatory genes and decreased expression of antiviraland antibody-related genes. Recent findings suggest that some psychological resilience factors may help buffer CTRA activation, but the relative impact of resilience and adversity factors remains poorly understood. Here we examined the relative strength of CTRA association for the two best-established psychological correlates of CTRA gene expression—the risk factor of perceived social isolation (loneliness) and the resilience factor of eudaimonic well-being (purpose and meaning in life). Methods: Peripheral blood samples and validated measures of loneliness and eudaimonic well-being were analyzed in 108 community-dwelling older adults participating in the longitudinal US Health and Retirement Study (56% female, mean age 73). Mixed effect linear model analyses quantified the strength of association between CTRA gene expression and measures of loneliness and eudaimonic well-being in separate and joint analyses. Results: As in previous studies, separate analyses found CTRA gene expression to be up-regulated in association with loneliness and down-regulated in association with eudaimonic well-being. In joint analyses, effects of loneliness were completely abrogated whereas eudaimonic well-being continued to associate with CTRA down-regulation. Similar eudaimonia-dominant effects were observed for positive and negative affect, optimism and pessimism, and anxiety symptoms. All results were independent of demographic and behavioral health risk factors. Conclusions: Eudaimonic well-being may have the potential to compensate for the adverse impact of loneliness on CTRA gene expression. Findings suggest a novel approach to targeting the health risks associated with social isolation by promoting purpose and meaning in life. © 2015 Elsevier Ltd. All rights reserved.
17 b -estradiol down-regulates lipopolysaccharide-induced MCP-1 production and cell migration in vascular smooth muscle cells

Atherosclerosis is an inﬂammatory disease where lipopolysaccharide (LPS) triggers the release of inﬂammatory cytokines that accelerate its initiation and progression. Estrogen has been proven to be vasoprotective against atherosclerosis; however, the anti-inﬂammatory function of estrogen in the vascular system remains obscure. In this study, we investigated the effect of estrogen on LPS-induced monocyte chemoattractant protein-1 (MCP-1; listed as CCL2 in the MGI database) production in vascular smooth muscle cells (VSMCs). LPS signiﬁcantly enhances MCP-1 production and this is dependent on nuclear factor k B (NF k B) signaling, since the use of NF k B inhibitor pyrrolidine dithiocarbamate or the silencing of NF k B subunit p65 expression with speciﬁc siRNA largely impairs LPS-enhanced MCP-1 production. On the contrary, 17 b -estradiol (E 2 ) inhibits LPS-induced MCP-1 production in a time- and dose-dependent manner, which is related to the suppression of p65 translocation to nucleus. Furthermore, p38 MAPK is rapidly activated in response to LPS, while E 2 markedly inhibits p38 MAPK activation. Transfection with p38 MAPK siRNA or the use of p38 MAPK inhibitor SB203580 markedly attenuates LPS-stimulated p65 translocation to nucleus and MCP-1 production, suggesting that E 2 suppresses NF k B signaling by the inactivation of p38 MAPK signaling. LPS promotes VSMCs migration and this is abrogated by MCP-1 antibody, implying that MCP-1 may play a major role as an autocrine factor in atherosclerosis. In addition, E 2 inhibits LPS-promoted cell migration by downregulation of MCP-1 production. Overall, our results demonstrate that E 2 exerts anti-inﬂammatory property antagonistic to LPS in VSMCs by reducing MCP-1 production, and this effect is related to the inhibition of p38 MAPK/NF k B cascade.
