Segmentation of remote sensing images using similarity measure based fusion-MRF model [PDF]

open access: yes, 2014
Classifying segments and detecting changes in terrestrial areas are important and time-consuming efforts for remote sensing image analysis tasks, including comparison and retrieval in repositories containing multitemporal remote image samples for the ...

Quantifying the informativeness of similarity measurements

open access: yesJ. Mach. Learn. Res., 2017
Summary: In this paper, we describe an unsupervised measure for quantifying the `informativeness' of correlation matrices formed from the pairwise similarities or relationships among data instances. The measure quantifies the heterogeneity of the correlations and is defined as the distance between a correlation matrix and the nearest correlation matrix

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Dimension and measure theory of self-similar structures with no separation condition

open access: yes, 2015
We introduce methods to cope with self-similar sets when we do not assume any separation condition. For a self-similar set K ⊆ ℝᵈ we establish a similarity dimension-like formula for Hausdorff dimension regardless of any separation condition.

A generalized similarity measure for similarity-based residual life prediction

open access: yes, 2011
Equipment residual life (RL) prediction is one of the essential elements of condition-based maintenance. Recently, some efforts are targeted towards similarity-based RL prediction.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9

open access: yesFEBS Letters, EarlyView.
Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...

Efficient Similarity Search in Structured Data [PDF]

open access: yes, 2004
Modern database applications are characterized by two major aspects: the use of complex data types with internal structure and the need for new data analysis methods.
