1-As NASA and other agencies continue to undertake ever challenging remote sensing missions, the ability of satellites and space probes to diagnose and autonomously recover from faults will be paramount. In addition, a more pronounced use of radiation-susceptible components in order to reduce cost makes the challenge of ensuring system dependability even more difficult. To meet these and other ...
This paper describes the first hand experiences of the electronic point of care (ePOC) project team and the project management and research and development issues that emerged over the course of a collaborative 3 year eHealth project. The paper highlights that despite the best of intentions by project managers, researchers and developers, a technologically innovative concept is no guarantee of ...
The United States radiation medical countermeasures (MCM) programme for radiological and nuclear incidents has been focusing on developing mitigators for the acute radiation syndrome (ARS) and delayed effects of acute radiation exposure (DEARE), and biodosimetry technologies to provide radiation dose assessments for guiding treatment. Because a nuclear accident or terrorist incident could poten...
Despite significant progress made over more than 15 years of research, structural biologists are still grappling with the issue of radiation damage suffered by macromolecular crystals which is induced by the resultant radiation chemistry occurring during X-ray diffraction experiments. Further insights into these effects and the possible mitigation strategies for use in both diffraction and SAXS...
Dr. Akashi started his medical career at Jichi Medical School (Tochigi Prefecture) as a junior resident of internal medicine in 1981. He next worked as a senior resident in the Division of Hematology of Jichi Medical School and in 1987 moved to the Division of Hematology/Oncology at UCLA School of Medicine in 1987. He received a Ph. D. from Jichi Medical School in 1988. He has been a staff memb...
OBJECTIVES The objective of this study was to review software errors known as single event upsets (SEUs) or bit flips due to cosmic rays in epilepsy neurostimulators. MATERIALS AND METHODS A case report of a single event upset or bit flip is discussed; device manufacturers and publicly available data were queried for both incidence and types of error as well as strategies of software error mi...
Interference among co-channel users is a fundamental problem in wireless networks, which prevents nearby links from operating concurrently. Directional antennas allow the radiation patterns of wireless transmitters to be shaped to form directed beams. Conventionally, such beams are assumed to improve the spatial reuse (i.e. concurrency) in indoor wireless networks. In this paper, we use experim...
The realization that mitigation efforts to reduce carbon dioxide emissions have, until now, been relatively ineffective has led to an increasing interest in climate engineering as a possible means of preventing the potentially catastrophic consequences of climate change. While many studies have addressed the potential effectiveness of individual methods there have been few attempts to compare t...
Our ability to use ionizing radiation as an energy source, as a therapeutic agent, and, unfortunately, as a weapon, has evolved tremendously over the past 120 years, yet our tool box to handle the consequences of accidental and unwanted radiation exposure remains very limited. We have identified a novel group of small molecule compounds with a 4-nitrophenylsulfonamide (NPS) backbone in common t...
