Magnetism of coupled spin tetrahedra in ilinskite-type KCu5_{5}O2_2(SeO3_3)2_2Cl3_3

Synthesis, thermodynamic properties, and microscopic magnetic model of ilinskite-type KCu$_{5}$O$_2$(SeO$_3$)$_2$Cl$_3$ built by corner-sharing Cu$_4$ tetrahedra are reported, and relevant magnetostructural correlations are discussed. Quasi-one-dimensional magnetic behavior with the short-range order around 50\,K and the absence of long-range order down to at least 2\,K is observed experimentally and explained in terms of weakly coupled spin ladders (tubes) with a complex topology formed upon fragmentation of the tetrahedral network. This fragmentation is rooted in the non-trivial effect of the SeO$_3$ groups that render the Cu--O--Cu superexchange strongly ferromagnetic.Comment: 9 pages, 7 figure

Ethical difficulties in clinical practice : experiences of European doctors

Background: Ethics support services are growing in Europe to help doctors in dealing with ethical difficulties. Currently, insufficient attention has been focused on the experiences of doctors who have faced ethical difficulties in these countries to provide an evidence base for the development of these services. Methods: A survey instrument was adapted to explore the types of ethical dilemma faced by European doctors, how they ranked the difficulty of these dilemmas, their satisfaction with the resolution of a recent ethically difficult case and the types of help they would consider useful. The questionnaire was translated and given to general internists in Norway, Switzerland, Italy and the UK. Results: Survey respondents (n = 656, response rate 43%) ranged in age from 28 to 82 years, and averaged 25 years in practice. Only a minority (17.6%) reported having access to ethics consultation in individual cases. The ethical difficulties most often reported as being encountered were uncertain or impaired decisionmaking capacity (94.8%), disagreement among caregivers (81.2%) and limitation of treatment at the end of life (79.3%). The frequency of most ethical difficulties varied among countries, as did the type of issue considered most difficult. The types of help most often identified as potentially useful were professional reassurance about the decision being correct (47.5%), someone capable of providing specific advice (41.1%), help in weighing outcomes (36%) and clarification of the issues (35.9%). Few of the types of help expected to be useful varied among countries. Conclusion: Cultural differences may indeed influence how doctors perceive ethical difficulties. The type of help needed, however, did not vary markedly. The general structure of ethics support services would not have to be radically altered to suit cultural variations among the surveyed countries

Recursiveness, Switching, and Fluctuations in a Replicating Catalytic Network

A protocell model consisting of mutually catalyzing molecules is studied in order to investigate how chemical compositions are transferred recursively through cell divisions under replication errors. Depending on the path rate, the numbers of molecules and species, three phases are found: fast switching state without recursive production, recursive production, and itinerancy between the above two states. The number distributions of the molecules in the recursive states are shown to be log-normal except for those species that form a core hypercycle, and are explained with the help of a heuristic argument.Comment: 4 pages (with 7 figures (6 color)), submitted to PR

The emergence of enterovirus D68 in England in autumn 2014 and the necessity for reinforcing enterovirus respiratory screening.

In autumn 2014, enterovirus D68 (EV-D68) cases presenting with severe respiratory or neurological disease were described in countries worldwide. To describe the epidemiology and virological characteristics of EV-D68 in England, we collected clinical information on laboratory-confirmed EV-D68 cases detected in secondary care (hospitals), between September 2014 and January 2015. In primary care (general practitioners), respiratory swabs collected (September 2013-January 2015) from patients presenting with influenza-like illness were tested for EV-D68. In secondary care 55 EV-D68 cases were detected. Among those, 45 cases had clinical information available and 89% (40/45) presented with severe respiratory symptoms. Detection of EV-D68 among patients in primary care increased from 0.4% (4/1074; 95% CI 0.1-1.0) (September 2013-January 2014) to 0.8% (11/1359; 95% CI 0.4-1.5) (September 2014-January 2015). Characterization of EV-D68 strains circulating in England since 2012 and up to winter 2014/2015 indicated that those strains were genetically similar to those detected in 2014 in USA. We recommend reinforcing enterovirus surveillance through screening respiratory samples of suspected cases

Remote UX Research in Unpredictable Times: Takeaways from Early Pandemic Practices

Copyright © 2023–2024, User Experience Professionals Association and the authors The recent global pandemic had shocking impacts on societies and economies worldwide by bringing complexity, ambiguity, and uncertainty for extended periods. UX researchers, faced with numerous challenges, were compelled to adapt to emergent conditions through remote research methods. Investigating how some members of the UX research community adapted to the emergency offers valuable insights into how they responded to uncertainty and showed resilience. Therefore, we studied the early practices of UX managers and researchers in Turkey during the first 6 months of the global pandemic under lockdown conditions. Our goal was to understand how UX research and design teams responded to uncertainty by customizing their methods. We focused on seven firms as different cases to conduct semi-structured interviews with seven managers and 13 UX researchers. The results demonstrate that the adaptable nature of UX research allowed them to quickly respond to these emerging conditions. In the early period of the pandemic, our study participants—UX managers, designers, and researchers—experienced the advantages and challenges of remote UX research necessitated by the lockdown. These included issues related to participant recruitment, work performance, readiness, and methodological concerns. Based on our findings, we make recommendations for UX researchers to conduct moderated and unmoderated remote research while maintaining inclusiveness and rigor.TÜBİTAK (The Scientific and Technological Research Council of Turkey).

Intelligent control system of metal vacuum sputtering process on the basis of application of multi-agent system

A vacuum sputtering process comprises evaporation of the material and subsequent vapor condensation on the substrates. Getting required and repeatable quality of coatings is challenging task. It depends on capabilities of equipment, type of evaporator, interaction evaporator with the evaporating substance and deposition process. Sputtering process parameters are determined by the ability evaporator to maintain a certain temperature evaporated substance for a long time. Controlling operations sequence of pumping and heating depends on achieving optimum vacuum conditions, in spite of used pumping method. The control system must foresee and identify emerging cracks or damage of the system components. This paper focuses on the development of intelligent control system vacuum process on the agent-based approach. © IDOSI Publications, 2013
