Molecular evolution: first enzymes, gases as substrates and genetic templates.
Rivista di biologia, 2002A fundamental problem in biology is the self-assembly of the first cells capable of growth and division under anoxic conditions on the Earth. Evolution proceeded by self-assembling and self-replicating cells that reproduced their own genetic information and also changed their genetic code over time.

Human linear template with mammographic backgrounds estimated with a genetic algorithm
Journal of the Optical Society of America A, 2007We estimated human observer linear templates underlying the detection of a realistic, spherical mass signal with mammographic backgrounds. Five trained naïve observers participated in two-alternative forced-choice (2-AFC) detection experiments with the signal superimposed on synthetic, clustered lumpy backgrounds (CLBs) in one condition and on ...

Autonomous Language Development Using Dialogue-Act Templates and Genetic Programming
IEEE Transactions on Evolutionary Computation, 2007In recent years, the concept of "autonomous mental development" (AMD) has been applied to the construction of artificial systems such as conversational agents, in order to resolve some of the difficulties involved in the manual definition of their knowledge bases and behavioral patterns.

Improved metal cluster deposition on a genetically engineered tobacco mosaic virus template
Nanotechnology, 2005Improved depositions of various metal clusters onto a biomolecular template were achieved using a genetically engineered tobacco mosaic virus (TMV). Wild-type TMV was genetically altered to display multiple solid metal binding sites through the insertion of two cysteine residues within the amino-terminus of the virus coat protein.

Previous attempts to produce nonenzymatic template-directed oligomerizations of activated pyrimidines on polypurine templates have been unsuccessful. The only efficient reactions are those where the template is composed primarily of pyrimidines, especially cytosine.

Template Selection for Lookup Table Based on Genetic Algorithm
2013A template selection method based on genetic algorithm was proposed for inverse halftoning in this paper. A constrained mathematical model was built to describe the template optimization problem. Since the existing greedy method was said not to find the globally optimum template, we solved this optimization problem by using genetic algorithm.

Object recognition by flexible template matching using genetic algorithms
1992We demonstrate the use of a Genetic Algorithm (GA) to match a flexible template model to image evidence. The advantage of the GA is that plausible interpretations can be found in a relatively small number of trials; it is also possible to generate multiple distinct interpretation hypotheses.

Optimizing Template for Lookup-Table Inverse Halftoning using Elitist Genetic Algorithm
IEEE Signal Processing Letters, 2015A template optimization method based on elitist genetic algorithm was proposed for lookup-table inverse halftoning. A mathematical model with constraint conditions was built to describe the template optimization problem. We solved this optimization problem by using elitist genetic algorithm and designed the details about encoding and decoding scheme ...

Template-Free Biometric-Key Generation by Means of Fuzzy Genetic Clustering
IEEE Transactions on Information Forensics and Security, 2008Biometric authentication is increasingly gaining popularity in a wide range of applications. However, the storage of the biometric templates and/or encryption keys that are necessary for such applications is a matter of serious concern, as the compromise of templates or keys necessarily compromises the information secured by those keys.
