新的独立成分分析算法实现功能磁共振成像信号的盲分离

采用独立成分分析(independent component analysis,ICA)的一种新的牛顿型算法来提取功能磁共振成像(functional magnetic rasonance imaging,fMRI)信号中的各种独立成分(包括与实验设计相关的成分以及各种噪声)。与fastICA相比,该算法减少了运算量,提高了运算速度,而且能够很好地分离出各个独立成分。结果表明该算法是一种有效的fMRI信号分析手段。

前胡族花粉外壁超微结构及其系统学意义(英文)

Transmission electron microscopy (TEM) observation of pollen grains of 18 species belongingto 18 respective genera of the tribe Peucedaneae Drude revealed distinct ultrastructural difference in thepollen exine, including the thickness and features of rectum, columnar layer, foot layer and endexine. Thesystematic position of those 18 species are re-evaluated based on their ultrastructural characteristics ofpollen exine observed in this study. Seven genera related to Angelica L. in Angelicinae Drude have beendeduced to genus Angelica L. For example, Osterfcum grosseserratum (Maxim.) Kitagawa was changed toAngelica L. by some authors, but it differs from Angelica sinensis (Oliv.) Diels in having well developedtectum which is thicker than the columnar layer and foot layer. Its columnar layer is quite well-developedwith long and branched columellae. Besides its surface is tuberculated. Evidently, its development exceedsthat of Angelica sinensis. However, it is only a moderate evolutional species in its genus, and the Angelicasinensis accounts as the most advanced species in Angelica Diels, thus, placing genus Ostencum Hoffm.in Angelica L is not suitable, it may be more appropriate to keep its original position. In addition, Ferulaakitschkensis B. Fedtsch. ex K.-Pol. differs greatly from those of Talassia transiliensis (Herd.) Korov. andSchumannia turcomnnia Kuntze, because of its very well-developed columnar layer, being about four tofive times thicker than the total of tectum and foot layer, tuberculated tectum surface and complicatedstructure of columnellae. As another species Heracleum forrestJ‘iWolff also differs from Semenovia rubtzovii(Schischk.) Monden. in having an even thickness of exine and well-developed columnar layer, it seemssuitable that they should also be treated as two independent genera.     

花卉聚焦野性之美

佛坪国家级自然保护区在自然地理划分上属于暖温带,但由于其西北面高峻庞大的秦岭主脊阻挡了北方寒冷气流的南侵,而其北高南低的地形与东南方的太平洋暖湿气流相迎,形成了这里冬无严寒,夏无酷暑的温暖潮湿气候;该区位于秦岭深山区,海拔高度980-2904米.境内山峦重叠、沟谷纵横,相对于整个秦岭山
