RNA viruses are a major human health threat. The life cycles of many highly pathogenic like influenza A virus (IAV) and Lassa depends on host mRNA, because viral polymerases cleave 5′-m7G-capped transcripts to prime mRNA synthesis ("cap-snatching"). We hypothesized that start codons within cap-snatched could generate chimeric human-viral mRNAs with coding potential. report the existence this mechanism gene origination, which we named "start-snatching." Depending reading frame,...

Summary In recent years, with the rapid development of adversarial learning technology, facial attribute editing has made great success in a number areas. Realistic visual effect, invariant identity information, and accurate area are three key issues editing. Unfortunately, most researches focus on former two problems. However, lack awareness task is main reason for damaging attribute‐irrelevant details. To address this issue, article proposes novel algorithm—a generative network (GAN)...

The new spaceborne high resolution synthetic aperture radar (SAR) sensors on board the TerraSAR-X satellites can achieve spatial up to 1m. In SAR image, signature of urban buildings be identified and extracted. Due side-looking character SAR, building usually presents as L-shaped bright linear feature caused by two sides that facing sensor, while echoes from other sides' lost. It's clear multi aspect image will helpful for this problem. This paper deals with footprint extraction dual-aspect...
