CoRRThis paper introduces Primary Breadth-First Development (PBFD) and Primary Depth-First Development (PDFD), two formally defined and verified methodologies for scalable, industrial-grade full-stack software engineering. These approaches bridge a longstanding gap between formal methods and real-world development practice by enforcing structural ...

山东省某地鹦鹉喙羽病病毒的全基因组序列及对SPF鸡胚的致病性探究
野生动物学报, 2019 2017年4月，山东省某鹦鹉场发生疑似喙羽病感染，鹦鹉出现异形喙和羽毛脱落，甚至急性猝死。目的：了解该地区鹦鹉喙羽病病毒（Psittacine beak and feather disease，PBFD）的流行现状、分子生物学特征和遗传变异规律，为PBFDV的防控提供参考依据。方法：收集怀疑有喙羽病病毒（PBFDV）感染的非洲灰鹦鹉的新鲜肝脏组织和羽毛样本，根据PBFDV全基因组序列设计特异性引物，从患病灰鹦鹉肝脏和羽毛组织中扩增PBFDV的全基因组序列，克隆到pMD19T载体中 ...
