    Some of the most dynamic areas of robotics research and development today are healthcare applications. Robot-assisted surgery, robotic nurses, in-home rehabilitation, and eldercare robots\u27 are all demonstrating rapidly iterating innovation. Rising healthcare labor costs and an aging population will increase demand for these human surrogates and enhancements. However, like many emerging technologies, robots are difficult to place within existing regulatory frameworks. For example, the federal Food, Drug, and Cosmetic Act (FD&C Act) seeks to ensure that medical devices (few of which are consumer devices) are safe, the HIPAA Privacy and Security Rules apply to data collected by health care providers (but not most consumer-facing hardware or software developers), and state licensing statutes oversee the conduct of doctors and nurses who, heretofore, have all been human beings

    Designing a broad-spectrum integrative approach for cancer prevention and treatment

    Targeted therapies and the consequent adoption of "personalized" oncology have achieved notablesuccesses in some cancers; however, significant problems remain with this approach. Many targetedtherapies are highly toxic, costs are extremely high, and most patients experience relapse after a fewdisease-free months. Relapses arise from genetic heterogeneity in tumors, which harbor therapy-resistantimmortalized cells that have adopted alternate and compensatory pathways (i.e., pathways that are notreliant upon the same mechanisms as those which have been targeted). To address these limitations, aninternational task force of 180 scientists was assembled to explore the concept of a low-toxicity "broad-spectrum" therapeutic approach that could simultaneously target many key pathways and mechanisms. Using cancer hallmark phenotypes and the tumor microenvironment to account for the various aspectsof relevant cancer biology, interdisciplinary teams reviewed each hallmark area and nominated a widerange of high-priority targets (74 in total) that could be modified to improve patient outcomes. For thesetargets, corresponding low-toxicity therapeutic approaches were then suggested, many of which werephytochemicals. Proposed actions on each target and all of the approaches were further reviewed forknown effects on other hallmark areas and the tumor microenvironment. Potential contrary or procar-cinogenic effects were found for 3.9% of the relationships between targets and hallmarks, and mixedevidence of complementary and contrary relationships was found for 7.1%. Approximately 67% of therelationships revealed potentially complementary effects, and the remainder had no known relationship. Among the approaches, 1.1% had contrary, 2.8% had mixed and 62.1% had complementary relationships. These results suggest that a broad-spectrum approach should be feasible from a safety standpoint. Thisnovel approach has potential to be relatively inexpensive, it should help us address stages and types ofcancer that lack conventional treatment, and it may reduce relapse risks. A proposed agenda for futureresearch is offered

    Context. The Gaia-ESO Public Spectroscopic Survey is an ambitious project designed to obtain astrophysical parameters and elemental abundances for 100 000 stars, including large representative samples of the stellar populations in the Galaxy, and a well-defined sample of 60 (plus 20 archive) open clusters. We provide internally consistent results calibrated on benchmark stars and star clusters, extending across a very wide range of abundances and ages. This provides a legacy data set of intrinsic value, and equally a large wide-ranging dataset that is of value for the homogenisation of other and future stellar surveys and Gaia's astrophysical parameters. Aims. This article provides an overview of the survey methodology, the scientific aims, and the implementation, including a description of the data processing for the GIRAFFE spectra. A companion paper introduces the survey results. Methods. Gaia-ESO aspires to quantify both random and systematic contributions to measurement uncertainties. Thus, all available spectroscopic analysis techniques are utilised, each spectrum being analysed by up to several different analysis pipelines, with considerable effort being made to homogenise and calibrate the resulting parameters. We describe here the sequence of activities up to delivery of processed data products to the ESO Science Archive Facility for open use. Results. The Gaia-ESO Survey obtained 202 000 spectra of 115 000 stars using 340 allocated VLT nights between December 2011 and January 2018 from GIRAFFE and UVES. Conclusions. The full consistently reduced final data set of spectra was released through the ESO Science Archive Facility in late 2020, with the full astrophysical parameters sets following in 2022. A companion article reviews the survey implementation, scientific highlights, the open cluster survey, and data products

    The Gaia-ESO Public Spectroscopic Survey: Implementation, data products, open cluster survey, science, and legacy

    Context. In the last 15 years different ground-based spectroscopic surveys have been started (and completed) with the general aim of delivering stellar parameters and elemental abundances for large samples of Galactic stars, complementing Gaia astrometry. Among those surveys, the Gaia-ESO Public Spectroscopic Survey, the only one performed on a 8m class telescope, was designed to target 100 000 stars using FLAMES on the ESO VLT (both Giraffe and UVES spectrographs), covering all the Milky Way populations, with a special focus on open star clusters. Aims. This article provides an overview of the survey implementation (observations, data quality, analysis and its success, data products, and releases), of the open cluster survey, of the science results and potential, and of the survey legacy. A companion article reviews the overall survey motivation, strategy, Giraffe pipeline data reduction, organisation, and workflow. Methods. We made use of the information recorded and archived in the observing blocks; during the observing runs; in a number of relevant documents; in the spectra and master catalogue of spectra; in the parameters delivered by the analysis nodes and the working groups; in the final catalogue; and in the science papers. Based on these sources, we critically analyse and discuss the output and products of the Survey, including science highlights. We also determined the average metallicities of the open clusters observed as science targets and of a sample of clusters whose spectra were retrieved from the ESO archive. Results. The Gaia-ESO Survey has determined homogeneous good-quality radial velocities and stellar parameters for a large fraction of its more than 110 000 unique target stars. Elemental abundances were derived for up to 31 elements for targets observed with UVES. Lithium abundances are delivered for about 1/3 of the sample. The analysis and homogenisation strategies have proven to be successful; several science topics have been addressed by the Gaia-ESO consortium and the community, with many highlight results achieved. Conclusions. The final catalogue will be released through the ESO archive in the first half of 2022, including the complete set of advanced data products. In addition to these results, the Gaia-ESO Survey will leave a very important legacy, for several aspects and for many years to come

    Diving into the vertical dimension of elasmobranch movement ecology

    Get PDF
    Knowledge of the three-dimensional movement patterns of elasmobranchs is vital to understand their ecological roles and exposure to anthropogenic pressures. To date, comparative studies among species at global scales have mostly focused on horizontal movements. Our study addresses the knowledge gap of vertical movements by compiling the first global synthesis of vertical habitat use by elasmobranchs from data obtained by deployment of 989 biotelemetry tags on 38 elasmobranch species. Elasmobranchs displayed high intra- and interspecific variability in vertical movement patterns. Substantial vertical overlap was observed for many epipelagic elasmobranchs, indicating an increased likelihood to display spatial overlap, biologically interact, and share similar risk to anthropogenic threats that vary on a vertical gradient. We highlight the critical next steps toward incorporating vertical movement into global management and monitoring strategies for elasmobranchs, emphasizing the need to address geographic and taxonomic biases in deployments and to concurrently consider both horizontal and vertical movements

    Regulating Healthcare Robots in the Hospital and the Home: Considerations for Maximizing Opportunities and Minimizing Risks

    Get PDF
    DRAFTSome of the most dynamic areas of robotics research and development today are healthcare applications. Demand for these robots will likely increase in the coming years due to their effectiveness and efficiency, an ageing population, the rising cost of healthcare, and the trend within the industry toward personalized medicine. But all-purpose “healthcare companions” and robotic “doctors” will not be available for purchase or be deployed in our hospitals any time soon. Rather, robots in healthcare will be an evolution in the coming decades. There are basic, pressing issues that need to be addressed in the nearer future in order to ensure that robots are able to maintain sustainable innovation with the confidence of providers, patients, consumers, and investors. We will only be able to maximize the potential of robots in healthcare through responsible design, deployment, and use, which must include taking into consideration potential issues that could, if overlooked, manifest themselves in ways that harm patients and consumers, diminish the trust of key stakeholders of robots in healthcare, and stifle long-term innovation by resulting in overly restrictive reactionary regulation. In this paper, we focus on the issues of patient and user safety, security, and privacy, and specifically the effect of medical device regulation and data protection laws on robots in healthcare. First, we examine the demand for robots in healthcare and assess the benefits that robots can provide. Second, we look at the types of robots currently being used in healthcare, anticipate future innovation, and identify the key characteristics of these robots that will present regulatory issues, including their increasing number of functions, complex data collection, processing, storing, and use practices, and increasing connectivity and potential for cloud usage, all resulting in an unprecedented expansion and centralization of patient data. Third, we examine the current regulatory framework within which these robots will operate, focusing on medical device regulation and data protection laws. Because we are likely to see health-related robots appearing in both conventional healthcare and consumer spaces, there will be regulatory disruption and the opportunity for regulatory arbitrage. We argue the regulation of both must change. In order to maximize robots’ potential and minimize risks to users, we will need to move towards some form of premarket review of robot “safety,” which should include broad considerations of potential harms, including security. Furthermore, current sector-based limitations that lead to gaps between, for example, FTC and HHS-OCR oversight, should be eliminated so that privacy and security interests can be better protected in the “HIPAA-free” zone. A foundational regulatory framework for both medical devices and consumers which is attuned to safety, security, and privacy will help foster innovation and confidence in robotics and ensure that we maximize the potential of robots in healthcare
