Smooth Non-negative Low-Rank Graph Representation for Clustering [PDF]

Jisuanji kexue yu tansuo
The existing low-rank graph representation algorithms fail to capture the global representation structure of data accurately, and cannot make full use of the valid information of data to guide the construction of the representation graph, then the ...

A generalised likelihood framework for partially observed capture-recapture-recovery models

, 2013
We provide a closed form likelihood expression for multi-state mark-recapture-recovery data when the state of an individual may be only partially observed.

GPU accelerated 3-D ultrasonic flaw imaging using full waveforms sampling and processing technique

Nihon Kikai Gakkai ronbunshu, 2015
We develop a three dimensional (3-D) flaw imaging system using the full waveforms sampling and processing (FSAP) technique and an ultrasonic matrix array transducer.

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

FEBS 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.

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

FEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Quasi-Analytical Model of the Transient Behavior Pressure in an Oil Reservoir Made Up of Three Porous Media Considering the Fractional Time Derivative

Mathematical and Computational Applications, 2020
The present work proposes a new model to capture high heterogeneity of single phase flow in naturally fractured vuggy reservoirs. The model considers a three porous media reservoir; namely, fractured system, vugular system and matrix; the case of an ...

Interpolated Plane Wave Imaging: IPWI

e-Journal of Nondestructive Testing, 2023
This paper offers a solution to the problems caused by sub-Nyquist spatial sampling in ultrasound image generation, which can result in aliasing and grating lobes in Full Matrix Capture (FMC) and Plane Wave Imaging (PWI). Neglecting the spatial sampling

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

SAR Target Recognition via Local Sparse Representation of Multi-Manifold Regularized Low-Rank Approximation

Remote Sensing, 2018
The extraction of a valuable set of features and the design of a discriminative classifier are crucial for target recognition in SAR image. Although various features and classifiers have been proposed over the years, target recognition under extended ...
