In this paper we summarize some of our results on aggregation of individual fuzzy preferences. We focus on aggregation functions that preserve some types of transitivity, by giving complete characterization and representation of two main aggregation classes. These are closely related to the weighted maximum and minimum operations. We also establish full characterization of these weighted forms ...

objective: to study the mechanisms involved in amyloid formation processes, we made a mammalian cell culture model of amylin aggregation and characterized its properties. materials and methods: amyloid fibrils were extracted from cho cells and binding affinity to thioflavin t and congo red was investigated. then the apple-green birefringence of extracted fibrils was detected under polarized li...

The parallel execution of aggregations is an interesting area. It be growing recently and plays important roles, thanks emerging application fields such as, e.g. data mining or sensor networks. The goal of distributed aggregation is to compute an aggregation function on a multi set of distributed values.Typical aggregation functions are max, sum, count, average, median, variance, kth smallest, ...

There are many studies reporting conflicting results of sex differences on various platelet functions. The purpose of this study was to investigate whether sex differences could affect platelet aggregation results using an optical method in healthy subjects. A total of 42 subjects, 21 males and 21 females, were included in the study. Platelet aggregation was induced by adenosine diphosphate (AD...

The main aim of this paper is to investigate bending behavior in sandwich plates with functionally graded carbon nanotube reinforced composite (FG-CNTRC) face sheets with considering the effects of carbon nanotube (CNT) aggregation. The sandwich plates are assumed resting on Winkler-Pasternak elastic foundation and a mesh-free method based on first order shear deformation theory (FSDT) is devel...

Wireless sensor network can be applied to both abominable and military environments. A primary goal in the design of wireless sensor networks is lifetime maximization, constrained by the energy capacity of batteries. One well-known method to reduce energy consumption in such networks is data aggregation. Providing efcient data aggregation while preserving data privacy is a challenging problem i...

We discuss how to aggregate multiple criteria evaluations belonging to qualitative, linearly ordered scales. Qualitative aggregation operations such as min or max can be refined by discrimin and leximin orderings, in agreement with the Pareto ordering of vector evaluations. Further refinements of discrimin orderings, as well as the generalization of discrimin and lexirnin to functions other tha...

This paper investigates the use of individual cross section data to describe macro functions. Necessary and sufficient conditions (denoted AS) are found for OLS slope coefficients from a cross section to consistently estimate the first derivatives of the macro function. AS embodies both sets of aggregation assumptions known; linear aggregation and sufficient statistics , and thus represents gen...

For all organisms promoting protein homeostasis is a high priority in order to optimize cellular functions and resources. However, there is accumulating evidence that aging leads to a collapse in protein homeostasis and widespread non-disease protein aggregation. This review examines these findings and discusses the potential causes and consequences of this physiological aggregation with age in...

This paper studies by means of reciprocal fuzzy binary relations the aggregation of preferences when individuals show their preferences gradually. We have characterized neutral aggregation rules through functions from powers of the unit interval in the unit interval. Furthermore, we have determined the neutral aggregation rules that are decomposable and anonymous. In this class of rules, the co...
