Types of Mimetics for the Design of Intelligent Technologies
2019
Mimetic design means using a source in the natural or artificial worlds as an inspiration for technological solutions. It is based around the abstraction of the relevant operating principles in a source domain. This means that one must be able to identify the correct level of analysis and extract the relevant patterns. How this should be done is based on the type of source. From a mimetic perspective, if the design goal is intelligent technology, an obvious source of inspiration is human information processing, which we have called cognitive mimetics. This article offers some conceptual clarification on the nature of cognitive mimetics by contrasting it with biomimetics in the context of in…
DESDEO: The Modular and Open Source Framework for Interactive Multiobjective Optimization
2021
Interactive multiobjective optimization methods incorporate preferences from a human decision maker in the optimization process iteratively. This allows the decision maker to focus on a subset of solutions, learn about the underlying trade-offs among the conflicting objective functions in the problem and adjust preferences during the solution process. Incorporating preference information allows computing only solutions that are interesting to the decision maker, decreasing computation time significantly. Thus, interactive methods have many strengths making them viable for various applications. However, there is a lack of existing software frameworks to apply and experiment with interactive …
Comparing interactive evolutionary multiobjective optimization methods with an artificial decision maker
2021
AbstractSolving multiobjective optimization problems with interactive methods enables a decision maker with domain expertise to direct the search for the most preferred trade-offs with preference information and learn about the problem. There are different interactive methods, and it is important to compare them and find the best-suited one for solving the problem in question. Comparisons with real decision makers are expensive, and artificial decision makers (ADMs) have been proposed to simulate humans in basic testing before involving real decision makers. Existing ADMs only consider one type of preference information. In this paper, we propose ADM-II, which is tailored to assess several …
Methoden und Daten zur Erforschung spezieller Organisationen: Parteien
2016
Die Parteienforschung ist eine interdisziplinare und theoretisch wie methodisch vielfaltige Forschung. Der Beitrag stellt relevante Methoden vor, die sich zur empirischen Erforschung von Parteien eignen und diskutiert Probleme aus der praktischen Forschungsarbeit. Dabei zeigt er die Relevanz der theoretischen Interdisziplinaritat wie der Methodentriangulation qualitativer und quantitativer Daten fur die Erstellung eines umfassenden Bildes politischer Parteien auf.
Comprehensive Analysis of Invasive and Noninvasive Investigation Methods in Peripheral Artery Disease
2019
Abstract Peripheral artery disease of the lower limbs is, in fact, an arterial pathology, by which the blood flow is reduced, due to the obstruction caused by the deposit of atheroma plaques.(1) This deposition occurs slowly, which leads to a slow progression of the disease, and thus, at the onset of symptomatology. The objective of the study was to make a comparison between the invasive and noninvasive paraclinical investigations performed in patients with peripheral arterial disease of the lower limbs in the E.C.C.H. Sibiu. In conclusion, between the two investigations (computed tomography angiography and digital subtraction angiography) there are no noticeable differences in the terminal…
Genomic characterization of a local epidemic Pseudomonas aeruginosa reveals specific features of the widespread clone ST395
2017
International audience; Pseudomonas aeruginosa is a ubiquitous opportunistic pathogen with several clones being frequently associated with outbreaks in hospital settings. ST395 is among these so-called 'international' clones. We aimed here to define the biological features that could have helped the implantation and spread of the clone ST395 in hospital settings. The complete genome of a multidrug resistant index isolate (DHS01) of a large hospital outbreak was analysed. We identified DHS01-specific genetic elements, among which were identified those shared with a panel of six independent ST395 isolates responsible for outbreaks in other hospitals. DHS01 has the fifth largest chromosome of …
Reference interval of monocyte distribution width (MDW) in healthy blood donors.
2020
Abstract Background The aim of the study was to accurately establish the reference interval (RI) of monocyte distribution width (MDW) in healthy blood donors by the direct method using different statistical approaches. Methods MDW was measured in 486 subjects. RI of MDW was calculated by the non-parametric method, the robust method and, the Harrell-Davis bootstrap method and using different tests to identify potential outliers (Dixon-Reed and Tukey). Results Lower and upper reference limits of the RI calculated by the non-parametric method were, 16.22 (90%CI 15.78–16.47) – 23.15 (90%CI 22.80–24.10) (without outlier removal), and 16.44 (90%CI 16.21–16.67) – 22.99 (90%CI 22.33–23.22) (after o…
Genome-Wide Estimation of the Spontaneous Mutation Rate of Human Adenovirus 5 by High-Fidelity Deep Sequencing
2016
Rates of spontaneous mutation determine the ability of viruses to evolve, infect new hosts, evade immunity and undergo drug resistance. Contrarily to RNA viruses, few mutation rate estimates have been obtained for DNA viruses, because their high replication fidelity implies that new mutations typically fall below the detection limits of Sanger and standard next-generation sequencing. Here, we have used a recently developed high-fidelity deep sequencing technique (Duplex Sequencing) to score spontaneous mutations in human adenovirus 5 under conditions of minimal selection. Based on >200 single-base spontaneous mutations detected throughout the entire viral genome, we infer an average mutatio…
New approach to generating insights for aging research based on literature mining and knowledge integration.
2017
The proportion of the elderly population in most countries worldwide is increasing dramatically. Therefore, social interest in the fields of health, longevity, and anti-aging has been increasing as well. However, the basic research results obtained from a reductionist approach in biology and a bioinformatic approach in genome science have limited usefulness for generating insights on future health, longevity, and anti-aging-related research on a case by case basis. We propose a new approach that uses our literature mining technique and bioinformatics, which lead to a better perspective on research trends by providing an expanded knowledge base to work from. We demonstrate that our approach …
Alternative Methods to Animal Testing in Safety Evaluation of Cosmetic Products
2018
Abstract This chapter reviews alternative methods recommended for animal testing in various toxicological areas. An alternative model to achieve complete animal replacement for acute toxicity testing is not possible. Skin corrosion/irritation alternative methods have been validated and accepted. For eye irritation testing, no single method is able to replace the Draize rabbit eye test. Skin sensitization methods imply refinement and reduction of numbers of animals. An in vitro dermal absorption test could be an alternative to in vivo testing. There are no generally accepted alternative methods to replace the usual repeated-dose toxicity in vivo assays. To determine the genotoxic and mutagen…
