To explore the feasibility of diagnosing microvascular invasion (MVI) with radiomics, to compare diagnostic performance different models established by each method, and determine best model based on radiomics.A retrospective analysis was conducted 206 cases hepatocellular carcinoma (HCC) confirmed through surgery pathology in our hospital from June 2015 September 2018. Among samples, 88 were MVI-positive, 118 MVI-negative. The radiomics process included tumor segmentation, feature...
Reservoir computing is a relatively recent computational paradigm that originates from recurrent neural network and known for its wide range of implementations using different physical technologies. Large reservoirs are very hard to obtain in conventional computers, as both the computation complexity memory usage grow quadratically. We propose an optical scheme performing reservoir over large networks potentially being able host several millions fully connected photonic nodes thanks...
With the ChemCam instrument, laser-induced breakdown spectroscopy (LIBS) has successively contributed to Mars exploration by determining elemental compositions of soil, crust and rocks. Two new lunched missions, Chinese Tianwen 1 American Perseverance, will further increase number LIBS instruments on after planned landings in spring 2021. Such unprecedented situation requires a reinforced research effort methods spectral data treatment. Although matrix effects correspond general issue LIBS,...
The matrix effects in LIBS analyses have been considered with univariate and machine learning based multivariate regression models for TAS classification of rocks.
This work demonstrates the efficiency of machine learning in correction spectral intensity variations laser-induced breakdown spectroscopy (LIBS) due to changes laser pulse energy, such can occur over a wide range, from 7.9 71.1 mJ our experiment. The developed multivariate model led precise determination concentration minor element (magnesium for instance) samples (aluminum alloys this work) with precision 6.3% (relative standard deviation, RSD) using LIBS spectra affected by energy change....
As any spectrochemical analysis method, laser-induced breakdown spectroscopy (LIBS) usually relates characteristic spectral lines of the elements or molecules to be analyzed their concentrations in a material. It is however not always possible for given application scenario, rely on such because various practical limitations as well physical perturbations spectrum excitation and recording process. This actually case determination carbon steel with LIBS operated ambient gas, where intense C I...
Abstract Human expanded potential stem cells (hEPSC) have been derived from human embryonic and induced pluripotent cells. Here direct derivation of hEPSC pre‐implantation embryos is reported. Like the reported hEPSC, embryo‐derived (hEPSC‐em) exhibit a transcriptome similar to morula, comparable differentiation potency, high genome editing efficiency. Interestingly, hEPSC‐em show unique H3 lysine‐4 trimethylation (H3K4me3) open chromatin conformation; they possess higher proportion H3K4me3...
Abstract With the ChemCam instrument, laser-induced breakdown spectroscopy (LIBS) has successively contributed to Mars exploration by determining elemental compositions of soils, crusts and rocks. American Perseverance landed since Feb 18, 2021 on Chinese Tianwen 1 planned for landing soon, further increase number LIBS instruments Mars. Such unprecedented situation requires a reinforced research effort methods spectral data treatment. Although matrix effects correspond general issue in LIBS,...
There have been a number of rapid advances in the prediction dynamics chaotic systems using technique known as Reservoir Computing. These techniques are mostly not effective for large networks, complexity task increases quadratically both time and memory. We report new Optical Computing multiple light scattering to accelerate recursive computation reservoir states. Different approaches information encoding based on phase or amplitude spatial modulations compared. demonstrate scalability good...
