One year old mixed-breed bitch was examined to retrieve in vivo matured oocytes. Laparotomy was performed 72 hr after ovulation determined by serum progesterone concentration, and abnormally enlarged left uterus horn was found. Both ovaries had eight corpus lutea, and a total 16 in vivo matured oocytes having perivitelline space within 25 µm, polar body, and metaphase II nucleus were recovered by flushing oviducts. This is the first study to confirm in vivo maturation of oocytes from a bitch with hydrometra, which suggests that oocytes recovered from canids with reproductive disease could be valuable sources for assisted reproductive technologies.
Hash function is a cryptographic primitive which conduct authentication, signature and data integrity. Recently, Wang et al. found collision of standard hash function such as MD5, SHA-1. For that reason, National Security Research Institute in Korea suggests a secure structure and efficient hash function, LSH. LSH consists of three steps, initialization, compression, finalization and computes hash value using addition in modulo , bit-wise substitution, word-wise substitution and bit-wise XOR. These operation is parallelizable because each step is independently conducted at the same time. In this paper, we analyse LSH structure and implement it over SIMD-SSE, AVX and demonstrate the superiority of LSH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
