Many long established US DOE facilities are in possession of poorly documented wastes in a variety of forms spanning a broad range of waste containers, waste matrices and isotopic mixtures. Existing assay technologies such as the SuperHENC can address many of the expected waste configurations. However, there are also expected waste items that fall outside the normal operating range of these exc...

Spin-torque-transfer (STT) magnetoresistive random-access memory (MRAM) [1-3], a successor to field-induced magnetic switching MRAM [4,5], is an emerging non-volatile memory technology that is CMOS-compatible, scalable, and allows for high-speed access. However, two circuit-level challenges remain for STT-MRAM: potentially destructive read access due to device variation and a high-power write a...

An increasing number of marine structures are utilizing composite materials. Major structure and components can be built lighter and corrosion-resistant using composite construction. The recreational boating industry has long recognized this and now commercial ferries are increasingly realizing fuel savings through weight reduction. The US Navy’s DDG-1000 topside structure and LPD-17 advanced e...

BACKGROUND Non-Inflammatory Destructive Periodontal Disease (NIDPD), is a severe destructive periodontal disease, that is characterized by the attachment loss and alveolar bone loss, without signs of the gingival inflammation, and the periodontal pocket development. OBJECTIVE Despite the fact that various cases of NIDPD have been reported; their etiology and disease evolution is still indefin...

John S. Popovics Summary Lasers are devices that create a high intensity, directed light beam. The light beam can travel in air or through fiber optic cables. Lasers can be used to generate waves and detect stretching or motion in a solid material without direct contact with the material. Thus lasers are useful in many important engineering applications that require remote non-destructive evalu...
