F-RFM-Miner: an efficient algorithm for mining fuzzy patterns using the recency-frequency-monetary model
In database marketing, recency, frequency, and monetary (RFM) analysis is an important tool to segment customers based on their recent purchase behaviors. By combining the RFM model with frequent pattern minin...

Open AccessDiurnal oscillations of epigenetic modifications are associated with variation in rhythmic expression of homoeologous genes in Brassica napus
Epigenetic modifications that exhibit circadian oscillations also promote circadian oscillations of gene expression. Brassica napus is a heterozygous polyploid species that has undergone distant hybridization and...

On Gevrey asymptotics for linear singularly perturbed equations with linear fractional transforms
A family of linear singularly perturbed Cauchy problems is studied. The equations defining the problem combine both partial differential operators together with the action of linear fractional transforms. The ...

Identification of Key Genes Associated with Colorectal Cancer Based on the Transcriptional Network
Colorectal cancer (CRC) is among the most lethal human cancers, but the mechanism of the cancer is still unclear enough. We aimed to explore the key genes in CRC progression. The gene expression profile (GSE41...

Multiparametric bifurcations of an epidemiological model with strong Allee effect
In this paper we completely study bifurcations of an epidemic model with five parameters introduced by Hilker et al. (Am Nat 173:72–88, 2009), which describes the joint interplay of a strong Allee effect and infe...

Algorithmic Reduction and Rational General Solutions of First Order Algebraic Differential Equations
First order algebraic differential equations are considered. A necessary condition for a first order algebraic differential equation to have a rational general solution is given: the algebraic genus of the equ...

Unique Orbital Normal Form for Vector Fields of Hopf-Zero Singularity
Normal forms for vector fields of Hopf-zero singularity in R3 are studied. Multiple Lie bracket method is used to give unique normal forms under both conjugacy and orbital equivalence for such vector fields with ...

Further Reduction of Normal Forms for Vector Fields
We study Lie's method in the way of Ushiki for further reduction of normal forms for vector fields with singularity at the origin. We give further reduction of normal forms in two typical cases for vector fiel...
