abstract background and purposes: gastrointestinal cancers including stomach adenocarcinoma are very prevalent and one the main causes of death due to cancer. mazandaran has a high mortality rate of stomach adenocarcinoma. this study was proposed for estimation of survival time in patients with stomach adenocarcinoma. materials and methods: the study was historical cohort. the samples were the ...

The MFA approach for simulations with dynamical fermions in lattice gauge theories allows in principle to explore the parameters space of the theory (e.g. the β,m plane for the study of chiral condensate in QED) without the need of computing the fermionic determinant at each point. We exploit this possibility for extracting both the renormalization group trajectories (”constant physics lines”) ...

The huge amount of data provided by genome-scale technologies makes discernible biological meanings difficult to access. Here, we report a powerful integrative method to combine genome-wide scale data sets and biological knowledge. Multiple Factor Analysis (MFA) is used to investigate jointly large observation data sets from different ’omic’ areas enriched with biological annotations. This mult...

Mean-field approximations (MFAs) are frequently used in physics. When a process (such as an epidemic or a synchronization) on a network is approximated by MFA, a major hurdle is the determination of those graphs for which MFA is reasonably accurate. Here, we present an accuracy criterion for Markovian susceptible-infected-susceptible (SIS) epidemics on any network, based on the spectrum of the ...

To achieve an insightful clustering of multivariate data, we propose subspace K-means. Its central idea is to model the centroids and cluster residuals in reduced spaces, which allows for dealing with a wide range of cluster types and yields rich interpretations of the clusters. We review the existing related clustering methods, including deterministic, stochastic, and unsupervised learning app...
