Breast cancer is the most common invasive cancer in women, affecting more than 10% of women worldwide. Microscopic analysis of a biopsy remains one of the most important methods to diagnose the type of breast cancer. This requires specialized analysis by pathologists, in a task that i) is highly time- and cost-consuming and ii) often leads to nonconsensual results. The relevance and potential of automatic classification algorithms using hematoxylin-eosin stained histopathological images has already been demonstrated, but the reported results are still sub-optimal for clinical use. With the goal of advancing the state-of-the-art in automatic classification, the Grand Challenge on BreAst Cancer Histology images (BACH) was organized in conjunction with the 15th International Conference on Image Analysis and Recognition (ICIAR 2018). BACH aimed at the classification and localization of clinically relevant histopathological classes in microscopy and whole-slide images from a large annotated dataset, specifically compiled and made publicly availab.e for the challenge. Following a positive response from the scientific community, a total of 64 submissions, out of 677 registrations, effectively entered the competition. The submitted algorithms improved the state-of-the-art in automatic classification of breast cancer with microscopy images to an accuracy of 87%. Convolutional neuronal networks were the most successful methodology in the BACH challenge. Detailed analysis of the collective results allowed the identification of remaining challenges in the field and recommendations for future developments. The BACH dataset remains publicly availab.e as to promote further improvements to the field of automatic classification in digital pathology. Copyright © 2018, The Authors. All rights reserved.

A 60 GHz fully differential power amplifier (PA) based on microstrip line (MSL) is presented in this paper. To accelerate design and characterization in EDA simulators circuit simulations, an equivalent substrate model extraction method for MSL is introduced. A differential three-stage cascode PA prototype is implemented in 65-nm bulk CMOS process for demonstration. The proposed PA has a 3-dB bandwidth ranging from 50 to 61 GHz, and generates saturation output power of 11.7 dBm with 20 dB gain, at 60 GHz. The test and simulation results agree well, indicating the effectiveness of the extracted model. This MSL model based design approach will pave a quick way for millimeter-wave power amplifier designs.

This paper presents one Convolutional Neural Network based single-frame Super-Resolution processing (CNNSR) for lensless blood cell counting, which takes one single low-resolution cell shadow image as the input and outputs an improved high-resolution one for better cell detection. Due to the advantage of lightweight and fully feed-forward structure, CNNSR is highly efficient and requires minimum resource for hardware implementation. One lensless imaging prototype integrating a 1.1-μm pixel-pitch back-side illuminated (BSI) CMOS image sensor and a microfluidic channel is further demonstrated, which shows clear detection of

Model and performance for nanometer MOSFET device and current mirror circuit considering random dopant fluctuation

引用

International Journal of Electrical Engineering 2015年第6期22卷 209-213页

As MOSFETs are scaled down to nanometer feature size, random dopant fluctuation (RDF) is crucial to the performance and yield of integrated devices and circuits. This paper presents a RDF-induced MOSFET current mismatch model for circuit analysis. The model is accurate and with 2.56% error compared to HSPICE Monte Carlo simulations. The performance parameters are derived with design decisions for MOSFET current mirror circuit considering RDF. Our simulation data confirm that IC designers should select appropriate dimensions and biasing conditions to meet the different specifications if RDF is taken into account in nanometer CMOS analog design.
