Alpha-amylase (EC 3.2.1.1) is a low-molecular-weight enzyme (approximately 45kDa) that cleaves the alpha-D-(1–4) glycan linkage of starch and glycogen. It has been in use as a diagnostic enzyme longer than any

Enigma是什么意思? 在耽美文中,指第四性别enigma,这类人可以标记其它三个性别,包括alpha, E能让alpha受孕生子,有易感期,成为专属于他们的Omega。有些enigma并不是一出生就可以判定的, 他们最初是alpha,成年后会二次分化成enigma,也有人强行与alpha结合,成功标记了alpha后,才发现自己是enigma。 Enigma也是一个音乐...

The autosomal dominant forms may have early onset in the first two decades of life, as in dHMN type I, which is usually rather severe and may lead to considerable weakness and wasting. However, no locus for dHMN I has been mapped so far. ...

我们在《基于SemiBeta的因子研究——多因子Alpha系列报告之(四十五)》报告中,借鉴Bollerslev(2021)的研究思路,基于个股收益和市场收益方向的不同,将传统Beta因子拆解为4个SemiBeta。回测结果显示,月频调仓频率下,基于日度收益计算的fBeta_MN(市场基准收益为负,股票收益为正)系列因子,整体表现较好。
(MNVEp, 13%) in compounds and the mean of periodic table rows (MPTR, 2.7%) play a key role in distinguishing metals from semiconductors. This has guiding significance for the design of corresponding materials. The fraction of B (fracB, 2.7%) and Ta (fracTa, 2.5%) are also important ...

Alpha的单端与平衡端的声底很接近,单端的声音较为轻松,适合长时间聆听。平衡端的声音框架饱满,细节更丰富。它在驱动力上的表现不错,并且拥有很强的适配性,我用它搭配了手头的几款耳机,整体听感都还不错,Alpha是那种不会出“恶”声的器材。 这款小尾巴的声场空间感不是那种夸张的类型,横向方面会多一些,能营造...
