Tibiotalocalcaneal arthrodesis is a salvage procedure undertaken for hindfoot problems that affect both the ankle and subtalar joints (eg, two-joint arthritis, severe acute trauma, osteonecrosis of the talus, severe malalignment deformities, significant hindfoot bone loss). Methods of achieving fusion include Steinmann pins, screws, plates, external fixators, and retrograde intramedullary nailing. Retrograde intramedullary nailing provides a load-sharing fixation device with superior biomechanical properties and is an excellent choice for use in tibiotalocalcaneal arthrodesis. This technique can be performed through relatively small incisions. In addition, recent design modifications include the availability of dynamization and the choice of curved or straight nails. Contraindications to the technique include the presence of infection, severe vascular disease, and severe malalignment of the tibia.

Fluid flow in porous media is important in many areas, including oil extraction and recovery, environmental protection, energy conservation, and the design and operation of fuel cells, solar cells, and batteries. Development of accurate, efficient, and reliable numerical schemes to simulate such fluid flow has received considerable attention in mathematics and engineering communities over the past decade. However, mathematical modeling and numerical simulation of fluid flows in heterogeneous media and realistic settings remain a challenge. Much of the difficulty in porous media flow simulations is due to the involvement of different length scales, from macroscopic scale to microscopic scale. This research project aims to develop accurate, efficient, and reliable numerical algorithms for flows in porous media. Weak Galerkin finite element methods (WGFEMs) will be developed for flows in highly heterogeneous domains, porous media, and complex flows in heterogeneous media. The methods under development are anticipated to significantly advance the utility of numerical analysis for realistic scientific and engineering applications. Graduate students are involved in the project.

This project aims to develop new weak Galerkin (WG) finite element methods (FEMs) with excellent flexibility in element construction and mesh generation, suited to dealing with heterogeneous physical parameters. Additionally, it is envisioned that the new multiscale WGFEMs will be applicable in other fields, such as structural analysis, electromagnetic wave scattering, image processing, and computer vision. Collaboration with petroleum industry partners is planned in this research project.

Non-intrusive and ambulatory health monitoring of patients? vital signs over Wireless Body Area Networks (WBANs) provides an economical solution to rising costs in the healthcare system. However, due to the lack of security in the operation and communication of resource-constrained medical sensor nodes, the health and medical information provided by the WBANs may not be trusted. To address this issue, lightweight security solutions that are suitable for capability and resource limited body sensor devices must be provided to authenticate the data transmission. The goal of this research project is to develop a lightweight authentication system for resource-constrained WBANs. Findings from the proposed project will provide support for ensuring real-time delivery of accurate and secure medical information in WBANs. The proposed research will also advance the fields of WBANs and trustworthy biomedical computing for healthcare applications. The proposed theories, models, and simulation code can be used by engineers and researchers to design and evaluate security mechanisms for WBAN applications. In addition, an important education objective tightly coupled with the proposed research is to recruit and educate future generation of WBAN engineers. This will be accomplished through curriculum development, student mentoring, and community outreach in these fast changing technical fields of WBAN system engineering, security and mobile health (mHealth).

The proposed research aims at realizing physical layer security approaches for WBANs and developing innovative key agreement and message authentication mechanisms. Unlike existing approaches (e.g., biometric-based approaches), the proposed authentication system does not require additional hardware, error reconciliation process and bit synchronization, and thus is suitable for resource-constrained and capacity-limited medical sensor nodes in WBANs. The proposed research tasks include (1) theoretical studies; (2) design of key agreement schemes; (3) development of message authentication system; and (4) system implementation and validation. The theoretical studies focus on the connections between the channel reciprocity, channel dependency and key generation. Based on the results of theoretical studies, practical key agreement schemes that use a set of dynamic wireless channel features among the communication partners will be developed. The project will then design a lightweight authentication system that is adaptive to wireless channels for securing medical data transmission in WBANs. Finally, the project will implement the proposed physical layer security approach in a real resource-constrained WBANs system and investigate the practical system performance limit through experiments. The findings from the project can provide guidelines for physical-channel based security system design and deployment of WBAN applications.

Cybersecurity competitions are an important component in security education and research, as they complement and enhance traditional pedagogical approaches. However, the benefits of security competitions may not be fully realized without addressing a few challenges in current security education including lack of competent training facilities and shortage of appropriate and shareable training materials that cater to security novices. Moreover, security competitions may be perceived as a burden to the many two or four year teaching institutions that lack the necessary resources. As a result, these institutions miss an opportunity to engage a large population of young talent in cybersecurity.

This research project seeks to address those challenges by developing a novel, virtual platform for both competition and education, namely PROMISE (Platform for Competition and Education in Cyber Security), and a set of learning and competition modules using the platform. Built on top of state-of-the-art, open-source cloud computing systems, the PROMISE platform is scalable and flexible and supports competitions of different styles as well as hands-on security puzzles, labs and projects, which makes it a versatile facility for both security competition and general education and research. The learning modules cover a variety of important security topics and each of them has four levels of content (including concept level content for learners with little security background) to engage learners with different backgrounds and interests. By sharing developed software and learning materials, collaborating with diverse institutions such as high schools and community colleges, and organizing cyber-defense competitions and professional development workshop, this project is expected to make both immediate and long-term impacts on cyber security competition and education.

This is a collaborative project involving the University of California, Davis (Award DUE-1525862), Diablo Valley College (Award DUE-1525057), Howard University (Award DUE-1524638), the College of Saint Benedict (Award DUE-1525021), Hope College (Award DUE-1524990), and the University of Arkansas, Little Rock (Award DUE-1525037).

This project will expand the content and capabilities of the STEMWiki Hyperlibrary, which was launched to provide vetted Science, Technology, Engineering, and Mathematics (STEM) learning resources to the public in the form of easily accessible, online college textbooks that alleviate the rising costs of postsecondary education. The STEMWiki Hyperlibrary consists of a number of connected, discipline-focused hypertext applications (ChemWiki, BioWiki, MathWiki, StatWiki, GeoWiki, PhysWiki), which are freely accessible to students regardless of socioeconomic or educational backgrounds. The ChemWiki ( is currently the most developed STEMWiki, with millions of visits each month. By making high-quality STEM learning resources readily available, the project will positively impact at least four main populations: (1) the non-science community; (2) socioeconomically disadvantaged students; (3) smaller or financially disadvantaged academic institutions, including high schools, that wish to adopt new learning technologies but cannot afford the initial steep costs of a new curriculum; and (4) discipline-based education researchers looking for a platform on which to evaluate new interdisciplinary approaches and curriculum modifications, which would otherwise absorb too large of a budget to develop from scratch. Once sufficiently developed, the Hyperlibary will be a power platform for the dissemination of new educational content and the evaluation of emerging educational technologies.

The STEMWiki Hyperlibrary is designed as a collaboratively constructed learning environment that enables the dissemination and evaluation of new educational resources and approaches as online course textbooks, with an emphasis on data-driven assessment of student learning and performance. The STEMWikis allow learners to cooperatively construct and organize knowledge, providing an important alternative to one size fits all instruction in which content is presented in a static, prepackaged manner. In this project, the investigators will augment the constituent STEMWikis of the Hyperlibrary with ancillary homework and simulation applications, as well as formative assessment modules. They will integrate the content of the STEMWikis both horizontally (across multiple STEM fields) and vertically (across multiple levels of complexity) within a network that will provide not just single textbooks but a rich hyperlibrary through which new, interconnected STEM textbooks can be constructed. The result will be an easy-to-use platform on which faculty members can collaborate to create and publish reusable, online pedagogical content. The project team will add ancillary online homework (the Student Ability Rating and Inquiry System [SARIS]) and simulations (via the ChemCollective, From these components, they will build an assessment infrastructure that tracks and correlates use of individual Wiki-based textbooks with simulations, homework activity, and exam performance, with the goal of identifying and tracking student performance across multiple STEM curricula.
