There is a tradeoff between generalization capability and computational overhead in multi-class leaing. We propose a generative probabilistic multi-class classi
Since the landmark work of R. E. Kalman in the 1960s, considerable efforts have been devoted to time series state space models for a large variety of dynamic es
群体感应(Quorum sensing)是细菌检测自身群体密度大小的环境信号感受系统,在细菌细胞间信息交流中具有极其重要的作用。Quorum sensing作为细菌中一种普遍存在的调控系统,能参与多种生物功能的调节,包括细菌生物发光、毒力基因的表达、抗生素的产生、胞外酶的合成、胞外多糖的合成、Ti质粒的结合转移、生物膜的形成等。本研究的目的就是利用这一调控机制,建立一套能够高效、简便的模型来筛选高
A dynamic network refers to a graph structure whose nodes and/or links dynamically change over time.Existing visualization and analysis techniques focus mainly
体育产业人人才培养面临的危机,已成为制约我国体育产业快速发展的瓶颈。通过对广西体育产业人才培养现状的梳理,指出缺乏人才需求预测、人才竞争力弱、体育产业整体环境发育
棉花是重要的经济作物之一,是主要的食用油料作物之一,同时也是纺织业不可或缺的重要材料,因而棉花在国民经济中的地位不容小觑。目前我国棉花的收获方式以人工为主,随着劳动力价格不断攀升,棉花生产用工量大,与其他作物的比较效益低,我国棉花种植面积正面临不断萎缩的困境。而采用机械收采,对棉花的株高及第一果枝节位高度要求比较高。目前,关于棉花高秆突变体的报道相对较少,尚未将其应用到育种中。因此,创造和发现新的
The purpose of the present work is to construct a reaction board based on fiber Bragg gratings (FBGs) that could be used for estimation of the 2D coordinates of
We give a brief review of the developments in terahertz time-domain spectroscopy (THz-TDS) systems and micro- cavity components for probing samples in the Unive
针对中国目前甜玉米育种的难点——果皮厚、柔嫩度差,该实验以超甜、普甜、普通玉米三种不同基因型的7个玉米自交系、4个杂交种作研究材料,在摸索甜玉米果皮厚度测定方法的基
