With the growth of automobile, machinery, and aerospace industries, demand for high-performance surface coatings having multifunctional characteristics use in mechanical parts is increasing. In this study, ternary/quaternary Mo–Cu–Cr–(N) nanocomposite were deposited at different N2 gas flow rates using direct current magnetron sputtering from a multicomponent single-alloy target. The target sim...

Picture archiving and communication systems (PACS) are typical information systems, which may be undermined by unauthorized users who have illegal access to the systems. This paper proposes a role-based access control framework comprising two main components – a content-based steganographic module and a reversible watermarking module, to protect mammograms on PACSs. Within this framework, the c...

Mo/N co-doped TiO2 nanotube array films were obtained by a combination of magnetron sputtering and anodization. The influences doping concentration morphology on the structure, morphology, elemental composition, light-absorption capacity, optoelectronic properties nanotubes studied. findings revealed that Mo was primarily incorporated into lattice in Mo6+ valence state, while N mainly embedded ...

The introduction of the Mammography Screening Program (MSP) in 2005 has changed the early detection of breast cancer in Germany significantly. We analyzed the frequency and ensuing health care costs of mammograms performed for the early detection of breast cancer before and after the introduction of the MSP. Furthermore, we analyzed the influence of the MSP on the demographics of physicians (gy...

Don't be square! A rare S(4) (2-) rectangle bridging two M(2)Cp(2)(mu(2)-CH(2))(2) (M=Rh, Ir) fragments is found to contain two "half-bonds" with S-S distances of 2.70 or 2.90 A. Computational studies explore the connection between these "half-bonds" and a Jahn-Teller distortion, as well as possible intermediates that form M(4)S(4) (2+) clusters having the S(4) (2-) rectangle rotated by 90 degr...

Previous research suggests that the right hemisphere (RH) may contribute uniquely to discourse and text processing by activating and maintaining a wide range of meanings, including more distantly related meanings. The present study used the word-lists false memory paradigm [Roediger, H. L., III, & McDermott, K. B. (1995). Creating false memories: Remembering words not presented in lists. Journa...

BACKGROUND While Medicare claims are a potential resource for clinical mammography research or quality monitoring, the validity of key data elements remains uncertain. Claims codes for digital mammography and computer-aided detection (CAD), for example, have not been validated against a credible external reference standard. METHODS We matched Medicare mammography claims for women who received...
