Here, we review some of the history and pathophysiology of lysosomal storage disorders to show how they have impacted on our knowledge of lysosomal biology. Although a significant amount of information has been ...

This paper addresses the inter-organizational network in response to an extreme event. Specifically, this paper analyzes interactions among public, private, and nonprofit organizations that evolved in response to the September 11, 2001 terrorist attacks. The research uses a theoretical framework primarily drawn from dynamic network theory and complex adaptive systems theory. ...

Perinatal nurses work with intricate systems requiring frequent interface with complex technology. This interplay is strongly influenced by the work environment and systems operations. The interplay among worker, technology, and the environment increases the risk of medical error, adverse patient outcomes, and in some instances, healthcare team member injury. Human factors ...

I have tried to describe some current research trends in seismology which are specifically directed toward solving the problem of detecting, locating, and identifying underground nuclear explosions. Attention has been directed specifically toward problems which arise in efforts to obtain information at distances in excess of 2500 kilometers. The main scientific advantage which ...

The perception of complex forms as a meaningful whole is a problem central to the understanding of vision. Part of this task can be viewed as computing the transformation which relates image features to parts of the object that are represented with respect to an intrinsic (object-centered) coordinate frame. Many advantages accrue if the representation is ...

PurposeTo examine semantic and lexical aspects of word learning over time.MethodThirty four 8-year-olds participated in vocabulary lessons for two weeks. Frequency of exposure and informativeness of semantic context were manipulated. A definition task assessed semantic learning and a naming task assessed lexical learning.ResultsLexical and semantic knowledge accrued over time ...

Most theories of attention propose that we maintain attentional templates in visual working memory to control what information is selected. In the present study, we directly tested this proposal by measuring the contralateral-delay activity (CDA) of human event-related potentials during visual search tasks in which the target is cued on each trial. Here we show that the CDA can be used to measure ...

Human intestinal intraepithelial lymphocytes (iIEL) are a unique population of predominantly CD8 alpha beta+, TCR alpha beta+ lymphocytes and, to a lesser extent, TCP gamma delta+ lymphocytes that proliferate poorly to anti-CD3 mitogenic signals but display significant cytolytic activity. Studies in mouse model systems have shown that the gamma chain of ...

Integrins regulate cell behavior through the assembly of multiprotein complexes at the site of cell adhesion. Parvins are components of such a multiprotein complex. They consist of three members (alpha-, beta-, and gamma-parvin), form a functional complex with integrin-linked kinase (ILK) and PINCH, and link ...

It is shown that the G matrix in the complex molecular orbitals method secular equation may be transformed into a Hermitian secular equation of the closed-shell method taking the final form ..sigma../sub ..nu../(G tilde/sub ..mu nu../ - (E - h/sub s/) delta/sub ..mu nu../))u*/sub ..nu gamma../ = epsilon/sub ..gamma../u*/sub ..mu ...

The experimental data on sedimentation behaviour of DNA-membrane complexes at radiation of the Chinese hamster cells (V79-4) in a wide dose range of sup 127 Cs gamma -rays, pulse neutrons (reactor IBR-2, Laboratory of Neutron Physics, JINR, Dubna) and acc...

PATH is a highly flexible shielding code utilizing the common point-kernel integration technique primarily for treating gamma radiation from reactors, radioactive components and from complex piping systems. Major features of the code include complex geometry capability, various source options, extensive data library, simple but ...

Highly enantioselective Michael addition of malonates to beta,gamma-unsaturated alpha-ketoesters has been promoted by chiral N,N'-dioxide-Yttrium(iii) complexes, providing the corresponding products in excellent yields with 94-99% ee values. PMID:20379595
