Texture-based Deep Neural Network for Histopathology Cancer Whole Slide Image (WSI) Classification
<p>Automatic histopathological Whole Slide Image (WSI) analysis for cancer classification has been highlighted along with the advancements in microscopic imaging techniques. However, manual examination and diagnosis with WSIs is time-consuming and tiresome. Recently, deep convolutional neural …

High-sensitivity Full-field Quantitative Phase Imaging Based on Wavelength Shifting Interferometry
… based on wavelength shifting interferometry (WSI) is proposed. On one hand, the full-field implementations, compared to point-scanning, spectral domain QPI techniques, require no mechanical scanning to form a phase image. On the other, WSI has the advantage of preserving the integrity of the …

Neural Networks For Phase Demodulation In Optical Interferometry
… known as wavelength shifting interferometry (WSI) which obtains the OPL by acquiring multiple interferograms at different, evenly spaced wavenumbers. Traditional phase demodulation algorithms for WSI fail to reach the theoretical OPL sensitivity limit set by the CRB. We have designed NNs which …

Investigation of KimiaNet's and DenseNet's deep features in lung cancer subtypes
… efficient representation of whole slide images (WSI). Through exploring deep features of lung cancer, it was discovered that some of these deep features have strong correlations with either lung adenocarcinoma (LUAD) or lung squamous carcinoma (LUSC). A deep feature-specific visualization …

Word sense disambiguation in clinical text
… disambiguation (WSD) and word sense induction (WSI) are the tasks of resolving this ambiguity. Applications in the clinical and biomedical domain focus on the potential disambiguation has for information extraction. Most approaches to the problem are unsupervised or semi-supervised because of …

Detecting basal cell carcinoma in skin histopathological images using deep learning
… a bag of scores for a given whole slide image (WSI), and attempted multiple ways of combining these scores to produce a single significant score to predict the presence of BCC in the given WSI. Our best performing model obtained an AUC of 0.991 in 86 samples of digital skin biopsies, 43 of which …

Timing-driven optimization problems in VLSI CAD
… identical standard cell based architectures and WSI arrays of blocks having a regular structure are the major architectures that are regular. The regularity of these architectures allows us to use powerful graph theoretic techniques that would not be possible otherwise.

Deep learning for digitized histology image analysis
… techniques to analyze the whole slide image (WSI). The process is as follows: 1) identification of epithelium by filtering the regions extracted from a low-resolution image with a binary classifier network; 2) epithelium segmentation; 3) deep regression for pixel-wise segmentation of …

Critical review of the South African Concrete Durability Index tests
… index (OPI), water sorptivity index (WSI), and chloride conductivity index (CCI) tests, respectively. Much work has been done over the past two decades in developing the DI tests to the present stage, where they are being, and have been, used in large projects such as the Gauteng …

Fabrication and characterization of multilayers for focusing hard x-ray optics
… studied were: W/C, Mo/Si, Ni/C, Ni-V/C, WSi₂/Si, and Nb/Si. The interface widths for W/C were about 4 [angstroms], but wider ([sigma] [greater than or equal to] 7 [angstroms]) for Mo/Si and Ni/C. The analysis indicated that the large Mo/Si interface width was due to the formation of a …

The influence of crystalline admixtures on the mechanical and durability properties of cracked and uncracked concrete
… properties, the influence of CAs on OPI, WSI, and water filled porosity tests were determined on uncracked concrete. OPI test results deduced that, CA-4 concrete recorded the highest decrease in permeability of 51.02% and 43.77% for w/b of 0.4 and 0.6, respectively. This was attributed to …

Deep learning on whole-slide images for early detection and risk prediction of oesophageal cancer
… diagnosis, and monitoring of disease. However, WSIs present a number of unique challenges for analysis, requiring special consideration of image annotations, slide and image artefacts, and evaluation of model performance. I have therefore developed SliDL, a Python library for performing pre- and …

Growth of amorphous tungsten silicide and study of the proximity effect at low dimensions for superconducting applications
… nitride (NbN) and amorphous tungsten silicide (WSi). These hybrid devices use the proximity effect to potentially be more efficient than either of the materials alone. In order to make these devices, we first grew high quality samples of tungsten silicide and characterized them before growing …
