关于“Fixed Points in Fuzzy Metric Spaces”一文的注记

Bifurcation analysis of two disc dynamos with viscous friction and multiple time delays

Bounded orbits such as closed, homoclinic and heteroclinic orbits are discussed in this work for a Lorenz-like 3D nonlinear system. For a large spectrum of the parameters, the system has neither closed nor homoclinic orbits but has exactly two heteroclinic orbits, while under other constraints the system has symmetrical homoclinic orbits.

Heteroclinic, Homoclinic and Closed Orbits in the Chen System

De novo motif discovery is a difficult computational task. Historically, dedicated algorithms always reported a high percentage of false positives. Their performance did not improve considerably even after they adapted to handle large amounts of chromatin immunoprecipitation sequencing (ChIP-Seq) data. Several studies have advocated aggregating complementary algorithms, combining their predictions to increase the accuracy of the results. This led to the development of ensemble methods. To form a better view on modern ensembles, we review all compound tools designed for ChIP-Seq. After a brief introduction to basic algorithms and early ensembles, we describe the most recent tools. We highlight their limitations and strengths by presenting their architecture, the input options and their output. To provide guidance for next-generation sequencing practitioners, we observe the differences and similarities between them. Last but not least, we identify and recommend several features to be implemented by any novel ensemble algorithm.

A review of ensemble methods for de novo motif discovery in ChIP-Seq data

In this paper a new concept of comparison function is introduced and discussed and some fixed point theorems are established for φ-contractive mappings in fuzzy normed linear spaces. In this way we obtain fuzzy versions of some classical fixed point theorems such as Nemytzki-Edelstein’s theorem and Maia’s theorem. c ©2017 All rights reserved.

Some fixed point theorems for φ-contractive mappings in fuzzy normed linear spaces

In this paper, a characterization for continuous product in a fuzzy normed algebra is established and it is proved that any fuzzy normed algebra is with continuous product. Another type of continuity for the product in a fuzzy normed algebras is introduced and studied. These concepts are illustrated by some examples. Also, the Cartesian product of fuzzy normed algebras is analyzed. c ©2016 All rights reserved.
