2015 Stem Cell Reports  
Notably, the cassettes employed one of two KLF4 variants, differing only by nine N-terminal amino acids, which generated dissimilar protein stoichiometry.  ...  Reprogramming responses varied in the extent of initiation and stabilization of transgene-independent pluripotency.  ...  ACKNOWLEDGMENTS We thank Kazutoshi Takahashi, Masamitsu Sone, and Ren Shimamoto for their critical readings of the manuscript, and Katsunori Semi for bioinformatics advice.  ...

Fast Multiplier Methods to Optimize Non-exhaustive, Overlapping Clustering

Yangyang Hou, Joyce Jiyoung Whang, David F. Gleich, Inderjit S. Dhillon
2016 Proceedings of the 2016 SIAM International Conference on Data Mining  
However, in real-world datasets, the clusters may overlap with each other. Furthermore, often, there are outliers that should not belong to any cluster.  ...  For the proximal augmented Lagrangian or proximal method of multipliers, we show a convergence result for the non-convex case with bound-constrained subproblems.  ...  We also compare the results with other stateof-the-art overlapping clustering methods, MOC [3] , ESA [15] , and OKM [8] .  ...

Mcoke: Multi-Cluster Overlapping K-Means Extension Algorithm

Said Baadel, Fadi Thabtah, Joan Lu
2015 Zenodo  
The algorithm is different from fuzzy clustering techniques because objects that overlap are assigned a membership value of 1 (one) as opposed to a fuzzy membership degree.  ...  Clustering involves the partitioning of n objects into k clusters. Many clustering algorithms use hard-partitioning techniques where each object is assigned to one cluster.  ...  The Overlapping K-means (OKM) [11] has a similar threshold to determine the belonging of an object.  ...

2014 Procedia CIRP  
Defining paths for robot tools is mainly limited by workspace of the applied robot, yielding to difficulties in layout design and programming, especially in complex cells.  ...  The tool itself is mounted to an adapter, which can be linked to multiple robots allowing a coordinated transfer of the tool between them.  ...  Other possible algorithms for overlapping clustering range from an Overlapping k-means clustering (OKM) over a Restricted-OKM (R-OKM) to fuzzy c-means clustering [2] , and can be differentiated according  ...

Concurrent binding to DNA and RNA facilitates the pluripotency reprogramming activity of Sox2

2020 Nucleic Acids Research  
Deletion of the RBM does not affect selection of target genes but mitigates binding to pluripotency related transcripts, switches exon usage and impairs the reprogramming of somatic cells to a pluripotent  ...  Sox2 targets RNA via a 60-amino-acid RNA binding motif (RBM) positioned C-terminally of the DNA binding high mobility group (HMG) box.  ...  We thank Dr Calista Keow Leng Ng (Institute of Medical Biology, Singapore) for the kind gift of the pETG20a-Sox1 plasmid.  ...
