Article container for dispensing reagent slides

A container for dispensing reagent slides into apparatus which uses the slides to carry out quantitative chemical analysis of fluid samples. The container is formed of a plurality of casing parts which, when joined together, for a generally rectangular housing with a chamber for receiving a stack of the slides. The container fits into a complementary shaped nest in the analysis apparatus and has discontinuity means for inhibiting improper orientation of the container in the nest. A notch code on the container cooperates with structure on the nest to inhibit placing into the nest a container carrying reagent slides improper for the analysis test to be conducted.
Synthesis and antitumor activity evaluation of novel oleanolic acid derivatives

Ten novel oleanolic acid (OA) derivatives were synthesized through modifications at positions of A ring and C-28. Inhibitory activities of the oleanolic acid derivatives against SGC7901 and A549 cell lines were evaluated and confirmed by the tetrazolium bromidesalt (MTT) assay. The lab results revealed that all these compounds displayed some antitumor activity against SGC-7901 and A-549 cell lines. Among them, II4 and II5 exhibited excellent antitumor activities against SGC7901 cells and A549 cells, compared with gefitinib. Molecular docking studies have shown that compounds II4 and II5 produce potent antitumor activities by interacting with C-kit receptor through hydrogen bonds and hydrophobic bonds.
Perspectives on More Than 3 Decades of the Voyager Mission

[1] Voyager 1 and Voyager 2, twin NASA probes that were launched from Cape Canaveral, Fla., in the summer of 1977 during a once-every-175-year alignment of the solar system's giant outer planets, changed our understanding about those planets—Jupiter, Saturn, Uranus, and Neptune—as well as the 4 dozen moons the spacecraft have flown by and the shape of the solar system itself. Today these 722-kilogram probes, whose instruments mostly are still operating after almost 34 years in space, are helping to rewrite the textbooks about the outer edge of our solar system as they continue to race outward from Earth. Voyager 1, currently 17.4 billion kilometers from Earth, and Voyager 2, 14.2 billion kilometers from Earth, are on their way to becoming the first human-made objects to leave the solar system and enter interstellar space, the medium between stars. In exclusive interviews with Eos and during a 27 April news briefing at NASA headquarters in Washington, D. C., Voyager project scientist Ed Stone and several others who have worked on the project discussed mission highlights and the probes' journeys through the heliosheath. This is the final outer layer of a kind of bubble the Sun creates around itself called the heliosphere, a margin where the solar wind is slowed by the pressure of interstellar gas. All the while, the spacecraft, still responsive to ground commands, are sending back data about the solar wind, the magnetic field carried out by the wind, charged particles, and plasma waves.
Crayfish Carapace Micro-powder (CCM): A Novel and Efficient Adsorbent for Heavy Metal Ion Removal from Wastewater

Crayfish carapace, a plentiful waste in China, was applied to remove divalent heavy metal ions—copper (Cu), cadmium (Cd), zinc (Zn), and lead (Pb)—from wastewater. The adsorption capacities of crayfish carapace micro-powder (CCM) for heavy metal ions were studied with adsorbent dosages ranging from 0.5–2.5 g/L and with initial metal concentrations ranging from 50–250 mg/L. CCM particle size, initial solution pH (from 2.5–6.5), temperature (from 25–65 °C) and calcium level (from 3.5–21.5%) were also varied in batch mode. The results indicated that the adsorption capacity increases with both decreasing particle size and increasing calcium level of the crayfish carapace. The kinetic studies indicated that the adsorption could be complete within 2 h, and that the data correlated with the pseudo-second-order model. CCM recorded maximum uptakes of 200, 217.39, 80, and 322.58 mg/g for Cu, Cd, Zn, and Pb, respectively. The adsorption capacities and removal efficiencies of CCM for metal ions were three-times higher than those of chitin and chitosan extracted from the CCM.
Probabilistic petrophysical-properties estimation integrating statistical rock physics with seismic inversion

A joint estimation of petrophysical properties is proposed that combines statistical rock physics and Bayesian seismic inversion. Because elastic attributes are correlated with petrophysical variables (effective porosity, clay content, and water saturation) and this physical link is associated with uncertainties, the petrophysical-properties estimation from seismic data can be seen as a Bayesian inversion problem. The purpose of this work was to develop a strategy for estimating the probability distributions of petrophysical parameters and litho-fluid classes from seismics. Estimation of reservoir properties and the associated uncertainty was performed in three steps: linearized seismic inversion to estimate the probabilities of elastic parameters, probabilistic upscaling to include the scale-changes effect, and petrophysical inversion to estimate the probabilities of petrophysical variables andlitho-fluid classes. Rock-physics equations provide the linkbetween reservoir properties and velocities, and linearized seismic modeling connects velocities and density to seismic amplitude. A full Bayesian approach was adopted to propagate uncertainty from seismics to petrophysics in an integrated framework that takes into account different sources of uncertainty: heterogeneity of the real data, approximation of physical models, measurement errors, and scale changes. The method has been tested, as a feasibility step, on real well data and synthetic seismic data to show reliable propagation of the uncertainty through the three different steps and to compare two statistical approaches: parametric and nonparametric. Application to a real reservoir study (including data from two wells and partially stacked seismic volumes) has provided as a main result the probability densities of petrophysical properties and litho-fluid classes. It demonstrated the applicability of the proposed inversion method.
BASES DA CULTURA DA VIOLÊNCIA VIVENCIADA POR ADOLESCENTES DO SISTEMA SOCIOEDUCATIVO DO RIO GRANDE DO NORTE

A problemática da cultura da violência e sua relação estrutural com o capitalismo tem atravessado visceralmente a vida de adolescentes envolvidos com o Sistema Nacional de Atendimento Socioeducativo - SINASE brasileiro. No Rio Grande do Norte, a Fundação de Atendimento Socioeducativo - FUNDASE é a responsável pela execução das medidas socioeducativas de semiliberdade e internação provisória. Evidencia-se que tal reprodução da cultura da violência em sociedade tem afetado a dinâmica familiar desses adolescentes e sido uma das motivações de envolvimento com o sistema socioeducativo potiguar. Ainda, reflete-se sobre as particularidades da categoria violência; explica-se de que maneira a cultura da violência tem afetado o seguimento juvenil; e verifica-se de que forma a FUNDASE tem buscado implementar a perspectiva socioeducativa junto aos adolescentes do sistema socioeducativo. Utiliza-se a pesquisa bibliográfica e documental como aportes. Percebe-se que, mesmo os/as adolescentes vivenciando estigmas sociais, preconceito de classe, gênero, racial e violências de diversas naturezas (física, psicológica, violação dos direitos humanos, abandono familiar, exclusão social, negação de direitos sociais), há um movimento de redimensionamento da política governamental brasileira no intuito de concretizar a implementação dos princípios e diretrizes de práticas socioeducativas numa perspectiva de inclusão social, de resgate de sua historicidade e de emancipação política desse seguimento.
States, firms and, sustainable economic growth: a view from the periphery

Persistent socioeconomic cleavages between world-leading and late industrialising peripheral countries threaten the post-crisis recuperation and undermine the sense of solidarity necessary to address the world’s most pressing challenges. Attenuating core-periphery asymmetries will be contingent on the ability of peripheral countries to generate sustainable economic growth, but there is no simple solution to achieve this. My project will address this challenge through a direct analysis of the productive and institutional structures of the two largest and most diversified peripheral economies, Spain and Korea, between 1985 and 2011. Using detailed case-studies of three industries based on a modified Global Value Chain methodology, the research will explore the character of state-firm interactions in these two countries and their role in shaping strategies for economic transformation as they upgraded from mid- to high-income economies. I will contend that upgrading in Spain and Korea was based on three factors: proactive states, coherent state structures, and symbiotic or co-dependent state-firm interactions. However, I will show that variations in the strategic and financial resources of state and firms, and in the influences of role-model countries, led Spain and Korea to pursue a different sectoral specialisation in complex services and manufacturing respectively. The research will be carried out at the University of California San Diego and the London School of Economics. The output will consist of a monograph and three academic papers. This project will enhance my career prospects by establishing me as an expert in economic transformation, expanding my publication record, developing my skills in international project management, and strengthening my international professional networks in the US and Asia. No less importantly, the results of the project will contribute to current European goals for smart, sustainable and inclusive growth.
High-level synthesis of approximate hardware under joint precision and voltage scaling

In recent years, approximate computing has emerged as a promising approach to trade off quality of computed outputs for energy savings. In this paper, we present an approximate high-level synthesis (AHLS) approach that outputs a quality-energy optimized register-transfer-level implementation from an accurate high-level C description. Existing AHLS work only considers switching activity for energy savings under hardware approximations. By contrast, we aim to provide a general AHLS solution that also considers voltage scaling given a reduced processing time. To maximize voltage and associated energy reductions, we include both operation-level approximations by bit rounding and more aggressive operation eliminations as approximation techniques. Optimally exploiting scaling opportunities under such approximations requires tight interaction with scheduling tasks. We address this problem by combining an optimization pass that estimates the scheduling impact of approximations with fast yet accurate quality-energy models and an efficient optimization solver to find near-optimal solutions constructively. Results show that when considering voltage scaling, up to 24.5% higher energy savings can be achieved compared to approaches that only consider switching activity. Our heuristic solver is able to find solutions within 0.1% of average energy savings compared to an exhaustive search, all while being up to 1,400 χ faster than simulation-based methods.
Separating principles below

In this paper, we study the Ramsey-type weak Kőnig's Lemma, written , using a technique introduced by Lerman, Solomon, and the second author. This technique uses iterated forcing to construct an ω-model satisfying one principle T1 but not another T2. The technique often allows one to translate a “one step” construction (building an instance of T2 along with a collection of solutions to each computable instance of T1) into an ω-model separation (building a computable instance of T2 together with a Turing ideal where T1 holds but this instance has no solution). We illustrate this translation by separating from (reproving a result of Ambos-Spies, Kjos-Hanssen, Lempp, and Slaman), and then apply this technique to separate from (which has been shown separately by Bienvenu, Patey, and Shafer).
Establishing future-oriented training and qualification quality standards for fostering a  broad uptake of sustainable energy skills in the european construction sector

TRAIN4SUSTAIN (T4S) will stimulate demand for skilled construction sector professionals (architects, contractors-SMEs and workers) through raising acceptance of regional and national qualifications and skills on the EU construction market. To this end, comparability of national qualifications and sustainable energy skills is key for increased transparency and penetration power in the market. T4S will tackle the issue of mutual recognition so that training accredited in one country is recognised easier in another country. Taking advantage of already available transnational energy skill qualification frameworks for building professions, like the BUILD UP Skills initiative, Prof/Trac scheme or the ones produced by the BIM community, and the recently developed EU framework for energy and resource efficient buildings (e.g. Level(s) ), T4S will focus on acting at market level. T4S project will foster a common understanding of sustainable energy skills across Europe by promoting a competence quality standard, a European Skills Registry and a Skills Passport for facilitating transnational recognition of learning outcomes and skill levels of existing qualifications and vocational trainings.
Cooperative au catalysis with chemically non-innocent ligands.

Gold catalysis has gathered increasing attention from the synthetic community during the last decades, due to the remarkable ability of Au centres to promote chemical transformations. Typically, gold catalysis is based on its peculiar properties as a Lewis acid, that make it very well suited for the activation of unsaturated bonds. On the other hand, the use of gold in more sophisticated processes, such as cooperative catalysis, is at its pioneering stage, and only few examples of these strategies are currently known. Metal-Ligand Cooperation strategies (MLC) are an emerging tool in homogeneous catalysis, based on the interplay between the metal centre and the non-innocent (bifunctional) ligand. This synergy vastly enhances the performances of known transformations, and even enables new sets of reactivities. MLC has been applied to many metal centres, often with spectacular results; Au-MLC strategies, however, are unknown to date. This project focuses on the development of a family of novel Au(III) complexes bearing Brønsted basic, non-innocent pincer ligands characteristics. Their fundamental study will be performed, assessing their Lewis acidity (especially in the Pearson HSAB scale), their Brønsted basicity, and their stoichiometric interaction with X–H bonds. Based on these results, their use as bifunctional Lewis-acid catalysts will be explored for the electrophilic activation of alkynes, carbonyl compounds, and alcohols. The design and development of sequential reactions involving the bifunctional gold catalysts obtained in the context of this project will be the ultimate, most ambitious goal of this action.
Limits as of -Laplacian concave–convex problems

Abstract We study the behavior as p → ∞ of the sequel of positive weak solutions of the concave–convex problem (P ) { − div ( | ∇ u | p − 2 ∇ u ) = λ u q ( p ) + u r ( p ) in Ω u > 0 in Ω u = 0 on ∂ Ω , where Ω ⊂ R n is a bounded domain, λ > 0 and the exponents q , r satisfy lim p → ∞ q ( p ) p − 1 = Q , lim p → ∞ r ( p ) p − 1 = R , with 0 Q 1 R . We characterize any positive uniform limit of a sequence of weak solutions of (P) as a viscosity solution of min { | ∇ u Λ | − max { Λ u Λ Q , u Λ R } , − Δ ∞ u Λ } = 0 in Ω . Notice that the limit process decouples the nonlinearity. We obtain existence, non-existence and global multiplicity of positive viscosity solutions of the limit problem in terms of the parameter Λ .

The implementation of projects will encourage meetings of potential business partners and will provide an excellent opportunity to promote the economic and investment of the region. The following events are planned: promotion of healthy food, economic promotion of the region or promotion of investment areas.
Peer learning of innovation agencies for advanced support to scale-ups

Following international evidence that shows that a small number of high-growth firms are vital for job growth and overall economic growth, and the European Commission's Start-up and Scale-up Initiative, Enterprise Europe Network (EEN) launched in 2017 a new flagship service to support scale-ups. However, innovation agency services are in too many occasions standardised and do not take into account the rapid evolving entrepreneurial ecosystem and the advanced needs of scale-ups. Innovation agencies across Europe need to be ready today to deliver advanced assessment services to scale-ups and be able to offer support tailored to their needs.
The objective of Scale-ups Ready is to enable the participating innovation agencies to exchange knowledge, know-how, and good practices on advanced methodologies and tools for scale-ups assessment (including SMEs with high-growth potential) and customised support services, in order to develop better approaches for client intake and support of scale-ups.
Based on the Twinning+ methodology, the project aims to cover peer-learning and peer-review activities for three kinds of services through specific assessment instruments that when combined offer in-depth analysis of the needs of scale-ups, in order to provide them with tailored support:
1) An advanced IP valuation scheme, IPscore® 2.2 (FORTH),
2) An advanced business innovation roadmap tool, smE-MPOWER ‘Business innovation roadmap tool’ (LIC),
3) An advanced Innovation Health Check assessment tool (FUNDECYT-PCTEX).
This peer-learning and peer-review scheme has been developed based on each partner's identified competences and gaps in advanced services for scale-ups. The result will bring in new added-value service offerings to participating organisations, will lead to better approaches and the adaptation of tools to the specific national/regional contexts. The Design Options Paper will be shared with other EU innovation agencies and networks, and with national and EU policy-makers.
Conductive diamond electrochemical oxidation of caffeine-intensified biologically treated urban wastewater

In this work, the usefulness of Conductive Diamond Electrochemical Oxidation (CDEO) to degrade caffeine in real urban wastewater matrixes was assessed. The oxidation of actual wastewater intensified with caffeine (from 1 to 100 mg L(-1)) was studied, paying particular attention to the influence of the initial load of caffeine and the differences observed during the treatment of caffeine in synthetic wastewater. The results showed that CDEO is a technology that is capable of efficiently degrading this compound even at very low concentrations and that it can even be completely depleted. Profiles of the ionic species of S (SO4(2-)), N (NH4(+), NO3(-)) and Cl (ClO(-), ClO3(-) and ClO4(-)) were monitored and explained for plausible oxidation mechanisms. It was observed that the efficiency achieved is higher in the treatment of real wastewater than in the oxidation of synthetic wastewater because of the contribution of electrogenerated oxidant species such as hypochlorite. The formation of chlorate and perchlorate during electrochemical processes was observed, and a combined strategy to prevent this important drawback was successfully tested based on the application of low current densities with the simultaneous dosing of hydrogen peroxide.
CLIR for Informal Content in Arabic Forum Posts

The field of Cross-Language Information Retrieval (CLIR) addresses the problem of finding documents in some language that are relevant to a question posed in a different language. Retrieving answers to questions written using formal vocabulary from collections of informal documents, as with many types of social media, is a largely unexplored subfield of CLIR. Because formal and informal content are often intermingled, CLIR systems that excel at finding formal content may tend to select formal over informal content. To measure this effect, a test collection annotated for both relevance and informality is needed. This paper describes the development of a small test collection for this task, with questions posed in formal English and the documents consisting of intermixed formal and informal Arabic. Experiments with this collection show that dialect classification can help to recognize informal content, thus improving precision. At the same time, the results indicate that neither dialect-tuned morphological analysis nor a lightweight CLIR approach that minimizes propagation of translation errors yet yield a reliable improvement in recall for informal content when compared to a straightforward document translation architecture.
A Structural Model of Cultural Tourism Supply Chain Collaboration on the R3A Route

This paper aims to evaluate the supply chain collaboration in the cultural tourism on the R3A route, which is starting from Kunming (China) to Luang Namtha (Lao PDR) and to Chiang Rai (Thailand).  The Structural Equation Model (SEM) was used to evaluate the key factors that have affected to the collaboration between partners along the route. Data were collected from 200 cultural tourism enterprises via self-administrative questionnaires. The result was found that lack of data sharing is the barriers of collaboration on cultural tourism in R3A route between supply chain partners. Information, commitment, and communication technology are the key factors to promote collaboration sustainability.
Modelling 2d transition metal dichalcogenide heterostructures

Although TMDs have been studied for decades, studies have been mostly limited to bulk materials. The properties of TMDs
in atomically thin 2D forms can be significantly different from those in the bulk, such as the size of the band gap, the nature
of the band gap (direct versus indirect), the existence of tightly-bound charged excitons. The physics of heterostructures
formed by stacking different kinds of TMD layers are even more versatile and unexpected. While recent studies have
experimentally demonstrated the possibility of synthesizing such novel 2D materials, the present project aims to study these
new types of materials from a theoretical standpoint. We will perform state-of-the-art first-principles simulations using the
most advanced exchange-correlation functionals developed in the host group for the accurate description of dynamical and
charge transfer process within the time dependent density functional theory (TDDFT) as well as many-body perturbation
approaches using the GW self-energy and including excitonic effects at the level of the Bethe Salpeter equation. We will
also develop and implement new multi-scale algorithms in the codes needed to handle some of the tasks detailed in the
project. This European Fellowship project will be hosted by a leading expert in the field, Prof. Angel Rubio of the University
of the Basque Country (Spain). The project will also involve collaboration with top international experiment groups. The
theoretical results acquired in this project will be used to guide and compare to experimental results with the goal of
developing novel devices for future advances in nanoelectronics, photoelectronics and plasmonics. The progress of this
project in exploring and understanding new physics of 2D TMDs and developing novel devices will have profound impacts on
condensed matter physics, material science, as well as nano- and bio-science in the next decade.
