SummaryPrincipal component analysis is a mathematical technique for summarizing a set of related measurements as a set of derived variates, frequently fewer in number, which are definable as independent linear functions of the original measurements. Consideration of their mathematical nature shows that they do not, themselves, necessarily correspond to sensible biological concepts, though they are more amenable to statistical study than the original measurements. Further, by assessing the extent to which they are in accordance with biological hypotheses, or with the results of other, similar, analyses, they can be transformed into other linear functions which are meaningful in the biological sense, or consistent with other results. Thus the specific technique of principal component analysis is developed into a more general component analysis approach. With proper regard for the purpose the analysis is intended to serve and for the mathematical restrictions involved, this approach can lead to a useful condensation of a mass of data, a better under-standing of the observed individuals as entities rather than collections of isolated measurements, and to the formulation of new hypotheses for subsequent examination.

Abstract This paper introduces a computational approach to three dimensional component layout that employs simulated annealing to generate optimal solutions. Simulated annealing has been used extensively for two dimensional layout of VLSI circuits; this research extends techniques developed for two dimensional layout optimization to three dimensional problems which are more representative of mechanical engineering applications. In many of these applications, miniaturization trends increase the need to achieve higher packing density and fit components into smaller containers. This research addresses the three dimensional packing problem, which is a subset of the general component layout problem, as a framework in which to solve general layout problems.

ABSTRACT We isolated and characterized spontaneous mutants with defects in the 147-amino-acid Salmonella protein FliJ, which is a cytoplasmic component of the type III flagellar export apparatus. These mutants, including ones with null mutations, have the ability to form swarms on motility agar plates after prolonged incubation at 30°C; i.e., they display a leaky motile phenotype. One mutant, SJW277, which formed significantly bigger swarms than the others, encoded only the N-terminal 73 amino acids of FliJ, one-half of the protein. At 30°C, overproduction of this mutant protein improved, to wild-type levels, both motility and the ability to export both rod/hook-type (FlgD; hook capping protein) and filament-type (FliC; flagellin) substrates. At 42°C, however, export was inhibited, indicating that the mutant FliJ protein was temperature sensitive. Taking advantage of this, we performed temperature upshift experiments, which demonstrated that FliJ is directly required for the export of FliC. Co-overproduction of FliJ and either of two export substrates, FliE or FlgG, hindered their aggregation in the cytoplasm. We conclude that FliJ is a general component of the flagellar export apparatus and has a chaperone-like activity for both rod/hook-type and filament-type substrates.

General Component

A model for describing the lifetimes of coherent systems, where the failures of components may have an impact on the lifetimes of the remaining components, is proposed. The model is motivated by the definition of sequential order statistics (cf. Kamps (1995)). Sequential order statistics describe the successive failure times in a sequentialk-out-of-nsystem, where the distribution of the remaining components' lifetimes is allowed to change after every failure of a component. In the present paper, general component lifetimes which can be influenced by failures are considered. The ordered failure times of these components can be used to extend the concept of sequential order statistics. In particular, a definition of sequential order statistics based on exchangeable components is proposed. By utilizing the system signature (cf. Samaniego (2007)), the distribution of the lifetime of a coherent system with failure-dependent exchangeable component lifetimes is shown to be given by a mixture of the distributions of sequential order statistics. Furthermore, some results on the joint distribution of sequential order statistics based on exchangeable components are given.

General Component

Legumes and rhizobium bacteria form a symbiosis that results in the development of nitrogen-fixing nodules on the root of the host plant. The earliest plant developmental changes are triggered by bacterially produced nodulation (Nod) factors. Within minutes of exposure to Nod factors, sharp oscillations in cytoplasmic calcium levels (calcium spiking) occur in epidermal cells of several closely related legumes. We found that Lotus japonicus, a legume that follows an alternate developmental pathway, responds to both its bacterial partner and to the purified bacterial signal with calcium spiking. Thus, calcium spiking is not restricted to a particular pathway of nodule development and may be a general component of the response of host legumes to their bacterial partner. Using Nod factor-induced calcium spiking as a tool to identify mutants blocked early in the response to Nod factor, we show that the L. japonicus Ljsym22-1 mutant but not the Ljsym30 mutant fails to respond to Nod factor with calcium spiking.

General Component

Doc2 is a C2-domain-containing protein that is highly expressed in the nervous system and has a constitutively expressed isoform. It has been implicated as a potential Ca2+ sensor in regulated exocytosis, and has been suggested to be associated with synaptic vesicles. To examine whether Doc2 is associated with synaptic-like microvesicles (SLMVs) or dense-core granules in neuroendocrine cells, we examined the distribution of Doc2 in subcellular fractionation of chromaffin cells of the adrenal medulla and in PC12 cells. Doc2 did not co-distribute with SLMVs from either cell type, but did appear to co-distribute with dense-core granules from PC12 cells. In contrast, it was not associated with the dense-core granules during subcellular fractionation of the adrenal medulla, and nor did it appear to be associated with endosomes, cis-Golgi or the trans-Golgi network. In contrast, Doc2 co-distributed under all conditions with a mitochondrial marker. We conclude that Doc2 is not a general component of regulated secretory vesicles, but may instead be associated with mitochondria.

General Component

Research on executive function in early childhood has flourished in recent years. Much of this work is premised on a view of executive function development as the emergence of a set of domain general component processes (e.g., working memory updating, inhibitory control, and shifting). This view has shaped how we think about relations between executive function and other aspects of development, the role of the environment in executive function development, and how best to improve executive function in children who struggle with it. However, there are conceptual and empirical reasons to doubt that executive function should be defined in this way. I argue executive function development is better understood as the emergence of skills in using control in the service of specific goals. Such goals activate and are influenced by mental content like knowledge, beliefs, norms, values, and preferences that are acquired with development and are important to consider in understanding children’s executive function performance. This account better explains empirical findings than the components view; leads to specific, testable hypotheses; and has implications for theory, measurement, and interventions.

General Component

The simple view of reading (SVR) framework has been used for decades to explain two general component skills considered to contribute to reading comprehension: decoding and linguistic comprehension. In the past, researchers have assessed the linguistic comprehension component using a wide range of language and/or listening comprehension measures that differed from each other. Many of those tasks did not align with the concept of linguistic comprehension originally proposed. Regardless, the studies’ outcomes were similar: The SVR model adequately represents the process of reading comprehension. In this article, I propose a common thread that links those diverse measurement tasks; all the tasks measured students’ metalinguistic skills. In fact, the findings from these studies mirror those found from investigations directly measuring the influence of language awareness abilities on reading comprehension. I conclude the article with the theoretical and educational implications of taking a different view of the second component of the SVR model.
