The space physics community continues to grow and become both more interdisciplinary and more intertwined with commercial and government operations. This has created a need for a framework to easily identify what projects can be used for specific applications and how close the tool is to routine autonomous or on-demand implementation and operation. We propose the Application Usability Level (AUL) framework and publicizing AULs to help the community quantify the progress of successful applications, metrics, and validation efforts. This framework will also aid the scientific community by supplying the type of information needed to build off of previously published work and publicizing the applications and requirements needed by the user communities. In this paper, we define the AUL framework, outline the milestones required for progression to higher AULs, and provide example projects utilizing the AUL framework. This work has been completed as part of the activities of the Assessment of Understanding and Quantifying Progress working group which is part of the International Forum for Space Weather Capabilities Assessment.

John S. Bell openly questioned the dominance of an orthodox quantum interpretation that had seemingly raised the principle of indeterminism from an epistemological question to an ontological truth in the late 1920s. He understood the inevitability of indeterminism to be a theoretical choice made by the founding architects of quantum theory, not a fundamental principle of reality necessitated by experimental facts. As a result, Bell decried the general lull in quantum interpretation debates within the physics community, and in particular, the complete omission of Louis de Broglie’s deterministic pilot wave interpretation from all theoretical and pedagogical discourses. This paper reexamines the pilot wave’s rise, abandonment, and subsequent omission in the history of quantum theory. What emerges is not a straightforward story of victimization and hegemonic marginalization. Instead, it is a story that grapples with tensions between the polyphony of individual voices and a physics community’s evolving identity and consensus in response to particular sociopolitical and scientific contexts. At the heart of these tensions sits an international scientific community transitioning from a politically fractured and intellectually divergent community to one embracing a somewhat forced pragmatic convergence around rationally reconstructed narratives and concepts like the impossibility of determinism. The story of the pilot wave’s omission gives us a window into the inherent power that theoretical choice and a congealing rhetoric of orthodoxy have on a scientific community’s consensus, pedagogical canons, and the future development of science itself.

The INSPIRE digital library has been serving the scientific community for the almost past 50 years. Previously known as SPIRES, it was the first web site outside Europe and the first database on the web. Today, INSPIRE connects more than 100’000 scientists in High Energy Physics worldwide, with over 1 million scientific articles, thousands scientific profiles of authors, data, institution, experiments, conferences and jobs in High Energy Physics. In order to bring INSPIRE to the next level, we recently rebuilt the platform based on modern tools and infrastructure and released the new INSPIRE version in beta a few months ago. To ensure a successful beta release, we worked closely with the High Energy Physics community to identify the users’ needs, drivers and barriers. In this paper, we describe the user-driven process that we followed, our testing strategy, as well as the user feedback following the INSPIRE beta release.

When a CME arrives at the Earth, it will interact with the magnetosphere, sometimes causing hazardous space weather events. Thus, the study of CMEs which arrived at Earth (hereinafter, Earth-impacting CMEs) has attracted much attention in the space weather and space physics communities. Previous results have suggested that the three-dimensional parameters of CMEs play a crucial role in deciding whether and when they reach Earth. In this work, we use observations from the Solar TErrestrial RElations Observatory (STEREO) to study the three-dimensional parameters of 71 Earth-impacting CMEs from the middle of 2008 to the end of 2012. We find that the majority Earth-impacting CMEs originate from the region of [30S,30N] × [40E,40W] on the solar disk; Earth-impacting CMEs are more likely to have a central propagation angle (CPA) no larger than half-angular width, a negative correlation between velocity and acceleration, and propagation time is inversely related to velocity. Based on our findings, we develop an empirical statistical model to forecast the arrival time of the Earth-impacting CME. Also included is a comparison between our model and the aerodynamic drag model.

In the past couple of years, we have been actively developing the Dynamic On-Demand Analysis Service (DODAS) as an enabling technology to deploy container-based clusters over hybrid, private or public, Cloud infrastructures with almost zero effort. DODAS is particularly suitable for harvesting opportunistic computing resources; this is why several scientific communities already integrated their computing use cases into DODAS-instantiated clusters, automating the instantiation, management and federation of HTCondor batch systems. The increasing demand, availability and utilization of HPC resources by and for multidisciplinary user communities, often mandates the possibility to transparently integrate, manage and mix HTC and HPC resources. In this paper, we discuss our experience extending and using DODAS to connect HPC and HTC resources in the context of a distributed Italian regional infrastructure involving multiple sites and communities. In this use case, DODAS automatically generates HTCondor batch system on-demand. Moreover it dynamically and transparently federates sites that may also include HPC resources managed by SLURM; DODAS allows user workloads to make opportunistic and automated use of both HPC and HTC resources, thus effectively maximizing and optimizing resource utilization. We also report on our experience of using and federating HTCondor batch systems exploiting the JSON Web Token capabilities introduced in recent HTCondor versions, replacing the traditional X509 certificates in the whole chain of workload authorization. In this respect we also report on how we integrated HTCondor using OAuth with the INDIGO IAM service.

The article analyzes the conducted activities for protection of several archaeological sites of the Ust-Chumysh microdistrict located at the mouth of the Chumysh River in the Talmensky District of the Altai Territory. It should be noted that it has been the first and the only experience of preventive protection measures in the Altai Territory so far. At the initiative of the scientific community, conservation measures started, which led to the creation of the only natural and historical reserve in Altai, one of its goals being the preservation of archaeological sites. Specific measures for completion of this work have been proposed. The positive results of such activities of interdepartmental interaction were in the absence of both natural and anthropogenic destruction in the analyzed archaeological microdistrict, which prompted us to formulate a proposal to share this experience, its essence being a creation of an interdepartmental working group with involvement of scientific community in order to include archaeological sites in the list of protected objects of the existing specially protected areas, with a subsequent change in their status from natural to natural-historical. Keywords: nature reserve, protection, archaeology, interaction, Altai Territory, microdistrict

An assessment of our physics-based understanding of solar-wind/magnetosphere coupling finds that the understanding is not complete. Solar-wind/magnetosphere coupling is foundational to magnetospheric physics and it is a key to comprehending and predicting space weather. We are modestly successful at correlating solar-wind variables with geomagnetic indices, but we lack the full knowledge to describe in detail how the shocked solar-wind plasma transports mass, momentum, and energy into the magnetosphere-ionosphere system and how the shocked solar wind drives geomagnetic activity and magnetospheric evolution. The controlling solar-wind factors that govern the driving of the magnetosphere-ionosphere system are not accurately known. Without this knowledge accurate predictions of the magnetospheric behavior cannot be made and no magnetosphere-ionosphere model will work correctly if it is driven incorrectly. Further, without a fundamental understanding, the prediction of the system reaction to some as-yet-unseen extreme solar-wind conditions will not be possible. In this perspective article several gaps in our knowledge are cataloged. The deficiencies in our physical understanding of solar-wind/magnetosphere coupling constitute a major unsolved problem for space physics (and for astrophysics), a problem that demands enhanced, coordinated research.

The computational demands for scientific applications are continuously increasing. The emergence of cloud computing has enabled on-demand resource allocation. However, relying solely on infrastructure as a service does not achieve the degree of flexibility required by the scientific community. Here we present a microservice-oriented methodology, where scientific applications run in a distributed orchestration platform as software containers, referred to as on-demand, virtual research environments. The methodology is vendor agnostic and we provide an open source implementation that supports the major cloud providers, offering scalable management of scientific pipelines. We demonstrate applicability and scalability of our methodology in life science applications, but the methodology is general and can be applied to other scientific domains.

<p>The Space Weather Technology, Research and Education Center (SWx TREC) is a center of excellence in cross-disciplinary research, technology, innovation, and education, intended to facilitate evolving space weather research and forecasting needs.  SWx TREC facilitates research advances, innovative missions, and data and computing technologies that directly support the needs of the SWx community to advance understanding and support closure of the Research to Operations (R2O) and Operations to Research (O2R) loop. Improving our understanding and prediction of space weather requires coupled Research and Operations. SWx-TREC is working to provide new research models, applications and data for use in operational environments, improving the Research-to-Operations (R2O) pipeline.  Advancement in the fundamental scientific understanding of space weather processes is also vital, requiring that researchers have convenient and effective access to a wide variety of data sets and models from multiple sources. The space weather research community, as with many scientific communities, must access data from dispersed and often uncoordinated data repositories to acquire the data necessary for the analysis and modeling efforts that advance our understanding of solar influences and space physics in the Earth’s environment. The University of Colorado (CU) is a leading institution in both producing data products and advancing the state of scientific understanding of space weather processes, and we are now hosting both an interoperable data portal providing streamlined, centralized, and event-based access to a wide variety of disparate data sets and also a community-accessible, Cloud-based testbed environment to support development, testing, transition, and use of new models, visualizations, algorithms, and forecast products.  In this presentation, we will describe our community-accessible testbed environment and demonstrate the Space Weather Data Portal.</p>
