An overview of the behavior of Fe-based superconductors (FBSs) in magnetic fields is given with the emphasis on the materials features important for pinning of vortices, critical current densities, melting of the vortex structures and the upper critical fields. We also discuss how the multiband electronic structure of FBSs can result in extremely high upper critical fields tunable by doping or in the Fulde-Ferrel-Larkin-Ovchinnikov inhomogeneous state at high fields and low temperatures. © 2011 IOP Publishing Ltd.

Sea ice in the Arctic Ocean is a key component of the modern climate system, but less is known about the evolution of Arctic sea ice throughout Earth's history, particularly in warmer climate states. Following early Palaeogene greenhouse conditions, seasonal sea ice in the Arctic developed during a period of relative cooling in the middle Eocene, some 47.5 million years ago. However, perennial sea ice has only been documented as recently as 18 million years ago. Here I document the provenance of iron grains in marine sediments from the central Arctic Ocean, and show that during several intervals, beginning about 44 million years ago, they were carried from distal Arctic shelf sources. The grains are too coarse to have been delivered by ocean currents or aeolian transport, and therefore must have been rafted by sea ice. Because grains entrained from the shelf sources would need to drift for more than one year to reach the depositional site, I conclude that sea ice must have persisted throughout the year. However, the presence of grains from these distal sources only occur in intervals of less than 100,000 years in the oldest part of the records, suggesting that perennial sea ice existed only ephemerally until 36.7 million years ago. © 2014 Macmillan Publishers Limited.

Unmanned Aircraft Systems (UAS) workforce studies recently completed by various organizations show that the utilization of UAS technology in the workplace is exploding in the domestic and international markets. UAS technology has the potential to impact nearly every sector of the economy and is revolutionizing manufacturing, emergency management, intelligence, agriculture, civil engineering, utility systems monitoring and package delivery. Because they have the ability to complete traditionally hazardous jobs more safely and difficult jobs more easily, UAS and related technologies are changing the way these tasks are performed. UAS have a cross-cutting impact on nearly every sector of the economy and every educational discipline. To take advantage of the opportunities provided by this emerging sector, the Geospatial Technician Education-Unmanned Aircraft Systems (GeoTEd-UAS) project, a three-year effort that focuses on geospatial technologies, will develop and implement academic courses and pathways to prepare Unmanned Aircraft Systems Operations Technicians (UASOT) to succeed in the emerging fields of geospatial data acquisition, analysis and exploitation.

The project will also provide faculty professional development and mentoring, curriculum development, and precollege activities to increase the UAS workforce pipeline. GeoTEd-UAS will build college and faculty capacity at two partnering community colleges and support these faculty to develop pathways for UASOT training. Activities include workforce needs and skills analysis, compilation of the duties and responsibilities of a UASOT, convening of leadership and faculty development workshops, faculty mentoring, curriculum development and student recruitment. The partnering community colleges represent rural and urban locations allowing the project to broaden the participation of many underrepresented groups. Project materials and resources will be shared nationally through the GeoTech Center and the GeoTEd website (http://geoted.org). GeoTEd-UAS project partners include Thomas Nelson Community College, Mountain Empire Community College, the Virginia Community College System, Virginia Tech, and the Virginia Space Grant Consortium (VSGC). The project will be led and administered by the VSGC. The innovative UASOT courses and pathways being developed through the GeoTEd-UAS project will advance the field significantly and serve as national models.

Annual Review of Condensed Matter Physics | Year: 2014

Since the discovery of high-Tc cuprates, the quest for new superconductors has shifted toward more anisotropic, strongly correlated materials with lower carrier densities and competing magnetic and charge-density wave orders. Although these materials' features enhance superconducting correlations, they also result in serious problems for applications at liquid nitrogen (and higher) temperatures and strong magnetic fields so that such conventional characteristics as the critical temperature Tc and the upper critical field Hc2 are no longer the main parameters of merit. This happens because of strong fluctuations of the order parameter, thermally activated hopping of pinned vortices, and electromagnetic granularity, as has been established after extensive investigations of cuprates and Fe-based superconductors (FBSs). In this paper, I give an overview of those mechanisms crucial for power and magnet applications and discuss the materials' restrictions that must be satisfied to make superconductors useful at high temperatures and magnetic fields. These restrictions become more and more essential at higher temperatures and magnetic fields, particularly for the yet-to-be-discovered superconductors operating at room temperatures. In this case, the performance of superconductors is limited by destructive fluctuations of the order parameter so that higher superfluid density and weaker electronic anisotropy, which reduce these fluctuations, can become far more important than higher Tc. © Copyright 2014 by Annual Reviews.

This award establishes a new Research Experiences for Undergraduates (REU) Site at Old Dominion University. The REU Site is led by faculty from the Center for Cybersecurity Education and Research (CCSER) at the university. CCSER includes faculty from a large number of departments and colleges across the university that can provide a range of multidisciplinary research projects that focus on problems that are important and attractive to undergraduates. The REU Site will host 10 students from across the nation to conduct research during the summer with faculty mentors. The students will live in the Cybersecurity Living and Learning Community associated with CCSER. The project plans to recruit a diverse cohort of undergraduate students each summer, including students from under-represented minorities, women, and veterans. In addition to their research activities, the students will participate in other professional development activities that will prepare them for entering the computing workforce and for possible futures as researchers.

The REU site is led by faculty mentors from the Center for Cybersecurity Education and Research. The faculty of the Center have significant research expertise and offer state-of-the-art facilities that should provide a compelling research experience to undergraduates. This REU site offers unique multidisciplinary learning and research opportunities for undergraduate students in the inherently multidisciplinary cybersecurity discipline. Students will explore topics across multiple disciplines including networks, machine learning, decision science, sociology, criminal justice, and philosophy. Students will be advised by a multidisciplinary mentoring committee with faculty from at least 3 different areas. This approach should promote multidisciplinary collaborations among students and increase their interest toward careers in the important field of cybersecurity.
