Suicidality: An Evolutionary Concept Analysis
Issues in Mental Health Nursing, 2020Suicide is a preventable health problem. Multiple definitions and inconsistent use of the term suicidality can result in failure to properly recognize suicide risk and behavior and confuses suicide research. Clarification of the suicidality concept is needed to facilitate the care for individuals at risk for suicide. Using Rodgers' evolutionary concept

Evolutionary analysis of aspartate aminotransferases
Journal of Molecular Evolution, 1995Aspartate aminotransferase isoenzymes are located in both the cytosol and organelles of eukaryotes, but all are encoded in the nuclear genome. In the work described here, a phylogenetic analysis was made of aspartate aminotransferases from plants, animals, yeast, and a number of bacteria.

Evolutionary analysis of ghrelin in Actinopterygii
Comparative Biochemistry and Physiology Part D: Genomics and ProteomicsGhrelin functions to stimulate appetite, promote the release of growth hormone, and regulate energy balance. Currently, research on the ghrelin is primarily focused on a single species, and there have been no systematic studies on the evolution of the ghrelin in fish.

Evolutionary analysis of the picornavirus family
Journal of Molecular Evolution, 1995An exhaustive evolutionary analysis of the picornavirus family has been carried out using the amino acid sequences of several proteins of the viruses including: the capsid proteins (1D, 1B, and 1C) situated at the 5' end of the genome and responsible for the serotype of the viruses, and the viral polymerase (3D), located at the 3' end of the genome ...

An analysis of evolutionary gradient search
Proceedings of the 2004 Congress on Evolutionary Computation (IEEE Cat. No.04TH8753), 2004Evolution strategies and gradient strategies are two different approaches to continuous optimization. Salomon's evolutionary gradient search procedure is a hybrid strategy that obtains gradient estimates by borrowing the idea of random variations from evolutionary computation.

Impostorism: An evolutionary concept analysis
Nursing Forum, 2018The aim of this study was to explore the concept of impostorism as applied to nursing and other disciplines.Impostorism has not been well defined or studied in nursing. Researchers have not studied connections between role transition stress of new graduates and impostorism, despite evidence that nursing students experience impostorism during ...

An Evolutionary Analysis of DBpedia Datasets
2018Linked Data, a method to publish interrelated data on the Semantic Web, has rapidly developed in recent years due to new techniques which enhance the availability of knowledge. As one of the most important central hubs of Linked Data, DBpedia is a large crowd-sourcing encyclopedia that contains diverse and multilingual knowledge from various domains in

Visual analysis of evolutionary algorithms
Proceedings of the 1999 Congress on Evolutionary Computation-CEC99 (Cat. No. 99TH8406), 2003The non-linear complexity of evolutionary algorithms (EAs) make them a challenge to understand. The difficulty in performing detailed analyses of an EA is in sorting through the large amount of of data that can be generated in a single run. This paper describes a visualization tool that facilitates navigation through the details of an EA run.

Evolutionary time-frequency analysis
Proceedings of the 2000 Congress on Evolutionary Computation. CEC00 (Cat. No.00TH8512), 2002Adapted waveform analysis uses libraries of bases and an efficient functional to match a basis to a given signal or family of signals. In particular, wavelet packets and localized trigonometric functions support the expansion of waveforms in bases whose elements have good time-frequency localization properties.
