Because environmental information is often suboptimal, visual perception must frequently rely on the brain's reconstruction of contours absent from retinal images. Illusory contour (IC) stimuli have been used to investigate these "filling-in" processes. Intracranial recordings and neuroimaging studies show IC sensitivity in lower-tier area V2, and to a lesser extent V1. Some interpret these dat...

We used soluble, C-fixing antibody/dsDNA IC to investigate immune complex (IC) handling and erythrocyte (E)-to-phagocyte transfer in chimpanzees. IC bound efficiently to chimpanzee E in vitro and showed minimal release with further in vitro incubation in the presence of serum in EDTA (less than or equal to 15% within 1 h). These IC also bound rapidly to E in vivo (70-80% binding within 1 min) a...

En el proceso de adquisición destrezas motrices la práctica es un elemento fundamental por que facilita aprendizaje, esta puede ser dos tipos: física o mental. El objetivo del presente estudio fue determinar tamaño efecto (PF), mental (PM) y combinada (PC), a lo largo retención en desempeño las motrices, utilizando enfoque metaanalítico análisis posibles variables moderadoras. Se utilizó modelo...

OBJECTIVES To assess perceptions of nursing staff regarding methicillin-resistant Staphylococcus aureus (MRSA), infection control (IC) and prevention strategies, barriers to IC, and IC resources. DESIGN Cross-sectional mixed methods study. SETTING Atlanta Veterans Affairs (VA) long-term care facility (LTCF). PARTICIPANTS Forty-two direct-care nursing staff employed at the LTCF during Augu...

Chips that produce correct results under operating conditions are called good chips. Some good chips may fail structural tests applied via scan chains (also called overkill chips). A reduction in supply voltage (also called supply voltage droop) due to the resistance of power-ground network is called IR-drop. IR-drop is investigated as a potential cause of overkill. IR-drop may slow down the sp...
