OBJECTIVE To celebrate over 30 years of health information systems' (HIS) evolution by bringing together pioneers in the field, members of the next generation of leaders, and government officials from several developing nations in Africa to discuss the past, present, and future of HISs. METHODS Participants gathered in Le Franschhoek, South Africa for a 2 1/2 day working conference consisting...
While hybrid functionals are largely responsible for the utility of modern Kohn-Sham density functional theory, they are not without their weaknesses. In the solid state, the slow decay of their nonlocal Hartree-Fock-type exchange makes hybrids computationally demanding and can introduce unphysical effects. Both problems can be remedied by a screened hybrid which uses exact exchange only at sho...
Health information systems (HISs) are typically seen as a mechanism for reducing medical errors. However, there is evidence to suggest that technology can facilitate or induce medical errors. Therefore, it is crucial that we fully test systems prior to their implementation in real-world settings. Presently, evidence-based evaluation heuristics that are specific to HISs do not exist for assessin...
Cells were recorded in the midbrain central gray neuropil of the cat that responded with action potentials only during fighting behavior and not while the cat was resting or while control manipulations were performed. Some other cells in the same region responded maximally during fighting, and all cells responded to at least one manipulation. Brain stimulation at sites of cells related to fight...
The gene-protein database was used to obtain the two-dimensional polyacrylamide gel coordinates of proteins phosphorylated in extracts of Escherichia coli including those phosphorylated by eukaryotic-like kinase activities. These suggest that the phosphoproteins correspond to, or co-migrate with, the product of an open reading frame at 1.3 min (Orf80), Enzyme 1 of the phosphoenolpyruvate-depend...
Background: This study aims to assess the level of self-determination skills acquired by deaf and hard hearing students (HISs) as perceived their teachers. And examine whether levels differ due variations in severity, type disability, students’ age, or teachers’ years experience independent variables. The dependent variable is skills.
 Methods: A descriptive-analytical method was used. sam...
Spurred by the success of perceptual models in audio coding applications, researchers have recently begun to address audio signal enhancement in a similar manner. Here we consider the case of musical recordings degraded by additive broadband noise such as tape hiss, in which the prevention of signal distortion is tantamount to noise removal. We review perceptually motivated approaches to music ...
