BACKGROUND Pentalogy of Cantrell (POC) is an extremely rare and complex congenital anomaly. Ultrasound is a valuable, safe, nonionizing, cost effective, widely available, and easily reproducible imaging tool and is indispensible in the diagnosis of POC. Despite the rarity of POC, it is imperative for a radiologist to be aware of its wide spectrum of presentation on ultrasound in first trimester...

Abstract Cell-aware test (CAT) explicitly targets faults caused by defects inside library cells to improve quality, compared with conventional automatic pattern generation (ATPG) approaches, which target only at the boundaries of cells. The CAT methodology consists two stages. Stage 1, based on dedicated analog simulation, characterization per cell identifies cell-level detects cell-internal de...

Drilling, one of the most used machining processes, has wide application in different industrial fields. Monitoring system health and operation status drilling process is essential for maintaining production efficiency. In this study, a convolutional neural network (CNN), deep-learning method, applied to defect diagnosis drill bits. Four bits with conditions were holes an aluminum block, vibrat...

BACKGROUND The concentrations of the pyrimidine "de novo" metabolites and their degradation products in urine are useful indicators for the diagnosis of an inborn error of the pyrimidine de novo pathway or a urea-cycle defect. Until now, no procedure was available that allowed the analysis of all of these metabolites in a single analytical run. We describe a rapid, specific method to measure th...
