中国科学院地理科学与资源研究所专利：利用ALPHA不变法插补地面缺失的涡动通量观测数据的方法。
人Alpha-2-巨球蛋白（humanalpha-2-macroglobulin，简称hA2M）是一种重要的广谱抑制小蛋白酶的大型糖蛋白（四聚体，分子量720KD），在人体血液中含量丰富。hA2M可以抑制几乎所有种类的小蛋白酶（分子量在80KD以下），以防止它们在血液中过量存在。同时，hA2M也是人身体内最“多才多艺”的蛋白之一，比如hA2M可以调节多种免疫细胞的功能，影响中性粒细胞的迁移和粘附并...

On the alpha value of polynomials in the tower number field sieve algorithm
number field sieve discrete logarithm pairing-friendly curve
2019/8/2
In this paper, we provide a notable step towards filling the gap between theory (estimates of running-time) and practice (a discrete logarithm record computation) for the Tower Number Field Sieve (TNF...
Hearing and seeing meaning in noise: Alpha, beta and gamma oscillations predict gestural enhancement of degraded speech comprehension
degraded speech gesture magnetoencephalography multimodal integration oscillations, semantics
2018/3/5
During face-to-face communication, listeners integrate speech with gestures. The semantic information conveyed by iconic gestures (e.g., a drinking gesture) can aid speech comprehension in adverse lis...

Prestimulus Alpha Oscillations Audio-visual Events
2017/8/29
Perceiving the temporal order of sensory events typically depends on participants' attentional state, thus likely on the endogenous fluctuations of brain activity. Using magnetoencephalography, we sou...

Alpha-Beta Gamma Rhythms Subserve Feedback Feedforward Influences Human Visual Cortical Areas
2016/5/3
Primate visual cortex is hierarchically organized. Bottom-up and top-down influences are exerted through distinct frequency channels, as was recently revealed in macaques by correlating inter-areal in...
Alpha and gamma band oscillations index differential processing of acoustically reduced and full forms
Cognitive load Neuronal oscillations Semantic integration Speech comprehension Speech reduction
2016/5/3
Reduced forms like yeshay for yesterday often occur in conversations. Previous behavioral research reported a processing advantage for full over reduced forms. The present study investigated whether t...
