野生动物学报, 1991 本文对麝鼠的染色体组型进行了初步分析研究,结果表明,麝鼠的二倍体染色体数为54,即2n=54,除一对中部着丝点外,其余全部为端部着丝点染色体,在染色体进化方面说明麝鼠的染色体组型是较原始的。

Memory-augmented Neural Machine Translation [PDF]
, 2017 Neural machine translation (NMT) has achieved notable success in recent times, however it is also widely recognized that this approach has limitations with handling infrequent words and word pairs. This paper presents a novel memory-augmented NMT (M-NMT)

野生动物学报, 2011 初步研究了吉林长白山地区的棕黑锦蛇染色体核型及Ag-NORs特征,并与已经报道的安徽产赤峰锦蛇有关特征进行对比。结果表明,吉林长白山地区的棕黑锦蛇染色体2n=36,由8对大型染色体和10对微小染色体组成,可分为A、B和C3组,性染色体属于ZZ/ZW型,Ag-NORs也都位于1对微小染色体上。棕黑锦蛇仅在第8对和W染色体的相对长度和臂比值上与赤峰锦蛇有差异,染色体其他特征,包括数目、形态、染色体类型等,在2蛇之间基本一致。锦蛇属染色体属名变化较大,但多数种类2n=36。棕黑锦蛇和赤峰锦蛇染色体数目相同 ...
