The geographical variation in animals’ social acoustical signals can reduce recognition across populations and may thus promote assortative mating, reproductive isolation and speciation. However, the social consequences of geographical variation in acoustical signals serving an ecological function are poorly known. Bat echolocation calls are considered to(More)
In this paper, we describe the architecture of our plant classification system for the LifeClef 2016 challenge [14]. The objective of the task is to identify 1000 species of images of plants corresponding to 7 different plant organs, as well as automatically detecting invasive species from unknown classes. To address the challenge [10], we proposed a plant(More)
This paper describes our proposal in the multi-organ plant identification task (LifeClef2017 challenge [8]). The objective of the challenge is to evaluate to what extent machine learning and computer vision can learn from noisy data compared to trusted data. To address the challenge, we employ our recent proposed hybrid generic-organ convolutional neural(More)
MicroRNAs (miRNAs) are a type of non-coding RNAs which are short (17-25nt) and highly conservative in evolution. They can regulate gene expression by preventing target mRNA translation or inducing degradation via oligonucleotides complementary to target mRNA. Here, we briefly summarize the functions and regulatory mechanisms of microRNA-181 (miR-181) in(More)
Akirin2 is an important nuclear factor which plays functions in innate immune response, myogenesis, muscle development, and carcinogenesis. In this study, akirin2 genes were cloned from 4-day-old Sanhuang and AA+ broiler, and its expression patterns were analyzed by RT-PCR. The results showed that there were four SNPs in the 5′-terminal region of akirin2(More)
Recently, avian viral diseases have become one of the main models to study mechanisms of viral infections and pathogenesis. The study of regulatory relationships and mechanisms between viruses and microRNAs has also become the focus. In this review, we briefly summarize the general situations of microRNAs encoded by avian herpesviruses. Also, we analyze the(More)
