BIOMART: Integracion de datos genotipicos, fenotipicos y climaticos de papa experiencias en el Centro Internacional de la Papa (CIP).
Integrating and sharing accession-level and omics-size genotype, phenotype and environmental data: Experiences at the International Potato Center (CIP).
Plant breeding consists in the creation and selection of new genotypes. This involves not only keeping records across generations and environments but also accommodating data of increasing resolution on genotypes, phenotypes, and growth environments. Some such high-resolution characterization methods are Near-Infrared spectroscopy, metabolomics, next-generation sequencing and high resolution spatial-temporal-spectral photos. A first need is the integration and retrieval of this information. Such an integrated and complete set can be described in breeder’s terms in six dimensions: a plant phenotype (P) is the result of a genotypes (G) interaction with its environment (E) given certain field management (M) practices. In addition, data on the administrative (A) context should be kept including staff involved, objectives and, if applicable, projects and donors; as well as on data documentation standards (S) like ontologies. The latter play an important part in exchanging and aggregating information. Here we describe the adoption of the ‘Biomart’ database for this purpose. While Biomart was developed originally to accommodate gene and sequencing data at a genomic scale we describe here how it can be used for breeding program data. This is being illustrated by current data warehousing in the potato breeding program at the International Potato Center (CIP). Particularly, genotype and phenotype can be transparently combined for further analysis in the decision process for the selection of new genotypes

Fred Tejada interviewed by Meleia Simon-Reynolds
In this interview, originally recorded in person, Fred Tejada speaks with Watsonville is in the Heart team member Meleia Simon-Reynolds. Fred talks about his father, Godofredo "Godo" Tana Tejada, who immigrated from the Philippines to the United States. He discusses how his father worked various jobs in Seattle and California, and he details his father's work as a foreman for the Bracero Program. Fred goes on to explain how his father met his mother, Meady Dalisay Solomeo in the Philippines, and how his parents moved to Watsonville together shortly after marrying. Fred talks about his father's work harvesting strawberry, lettuce, and brussel sprouts, and he discusses his mom's work in the fields during the day and at the pajama factory at night. Fred remembers helping his father in the fields throughout his adolescence, as well as he recalls his family housing many manong while they lived in Watsonville
Prioritizing Residents\u27 Needs: On the Creation of a Residents as Teachers and Leaders Program
Introduction: Residents are responsible for the majority of medical student teaching and directly supervise, instruct, and evaluate students. Many organizations now recommend that residency training programs include venues specifically designed to develop resident teaching skills. [See PDF for abstract]
Effect Of Gender On T-Cell Proliferative Responses To Myelin Proteolipid Protein Antigens In Patients With Multiple Sclerosis And Controls
Multiple sclerosis (MS) is an inflammatory demyelinating disorder of the central nervous system. Gender influences both susceptibility to MS, with the disease being more common in women, and the clinical course of disease, with an increased proportion of males developing the primary progressive form of the disease. The basis for these differences may include genetic and immunological factors, and the immunological differences between men and women may be influenced by the effects of the sex hormones. Over several years we have collected blood from MS patients and controls, and measured T-cell responses to myelin proteolipid protein (PLP) and myelin basic protein (MBP) and have shown increased responses to PLP in MS patients compared to healthy controls and patients with other neurological diseases. In the present study we analyzed data from over 500 individuals, to determine whether there are differences between males and females in their responses to PLP and MBP. We found that there was higher frequency of increased T-cell reactivity to immunodominant PLP peptides in women than in men, particularly in non-MS individuals. We suggest that this may be relevant to the higher prevalence of MS in women
Identification of novel CD8+ T cell epitopes in human herpesvirus 6B U11 and U90
Human herpesvirus 6B (HHV6B) infects over 90% of the population, and normally establishes a latent infection, where episodes of reactivation are asymptomatic. However, in immunocompromised patients HHV6B reactivation is associated with high morbidity and mortality. Cellular immunotherapy has been utilised against other herpesvirus in immunocompromised settings. However, limited information on the immune response against HHV6B has hampered the development of immunotherapy for HHV6B-driven disease. In this study we have analysed the cellular immune response against four HHV6B antigens in a panel of 30 healthy donors. We show that the base-line level of T cell reactivity in peripheral blood is very low to undetectable. A short-term reactivation step enabled expansion of T cell responses, and all donors responded to at least 1 antigen, but more commonly 3 or 4. A hierarchy of immunogenicity was determined with antigens U90 and U54 being co-dominant, followed by U11 and U39. Putative CD8+ T cell epitopes were mapped to U90 and U11, predicted to be presented in the context of HLA-A1, A29, B39 and C6. T cells reactive against these novel epitopes were able to recognise virus-infected cells. Our data is supportive of the application and on-going development of T cell immunotherapy against HHV6B-driven disease in the immunocompromised host
A Circular Economy of Electrochemical Energy Storage Systems: Critical Review of SOH/RUL Estimation Methods for Second-Life Batteries
Humanity is facing a gloomy scenario due to global warming, which is increasing at unprecedented rates. Energy generation with renewable sources and electric mobility (EM) are considered two of the main strategies to cut down emissions of greenhouse gasses. These paradigm shifts will only be possible with efficient energy storage systems such as Li-ion batteries (LIBs). However, among other factors, some raw materials used on LIB production, such as cobalt and lithium, have geopolitical and environmental issues. Thus, in a context of a circular economy, the reuse of LIBs from EM for other applications (i.e., second-life batteries, SLBs) could be a way to overcome this problem, considering that they reach their end of life (EoL) when they get to a state of health (SOH) of 70–80% and still have energy storage capabilities that could last several years. The aim of this chapter is to make a review of the estimation methods employed in the diagnosis of LIB, such as SOH and remaining useful life (RUL). The correct characterization of these variables is crucial for the reassembly of SLBs and to extend the LIBs operational lifetime
A Plea for Risk
Mountaineering is a dangerous activity. For many mountaineers, part of its very attraction is the risk, the thrill of danger. Yet mountaineers are often regarded as reckless or even irresponsible for risking their lives. In this paper, we offer a defence of risk-taking in mountaineering. Our discussion is organised around the fact that mountaineers and non-mountaineers often disagree about how risky mountaineering really is. We hope to cast some light on the nature of this disagreement – and to argue that mountaineering may actually be worthwhile because of the risks it involves. Section 1 introduces the disagreement and, in doing so, separates out several different notions of risk. Sections 2–4 then consider some explanations of the disagreement, showing how a variety of phenomena can skew people’s risk judgements. Section 5 then surveys some recent statistics, to see whether these illuminate how risky mountaineering is. In light of these considerations, however, we suggest that the disagreement is best framed not simply in terms of how risky mountaineering is but whether the risks it does involve are justified. The remainder of the paper, sections 6–9, argues that risk-taking in mountaineering often is justified – and, moreover, that mountaineering can itself be justified (in part) by and because of the risks it involves
Viewing Visual Analytics as Model Building
To complement the currently existing definitions and conceptual frameworks of visual analytics, which focus mainly on activities performed by analysts and types of techniques they use, we attempt to define the expected results of these activities. We argue that the main goal of doing visual analytics is to build a mental and/or formal model of a certain piece of reality reflected in data. The purpose of the model may be to understand, to forecast or to control this piece of reality. Based on this model-building perspective, we propose a detailed conceptual framework in which the visual analytics process is considered as a goal-oriented workflow producing a model as a result. We demonstrate how this framework can be used for performing an analytical survey of the visual analytics research field and identifying the directions and areas where further research is needed
