Although the oil body is known to be an important membrane enclosed compartment for oil storage in seeds, we have little understanding about its biogenesis during embryogenesis. In the present study we investigated the oil body emergence and variations in Brassica napus cv. Topas. The results demonstrate that the oil bodies could be detected already at the heart stage, at the same time as the embryos began to turn green, and the starch grains accumulated in the chloroplast stroma. In comparison, we have studied the development of oil bodies between Arabidopsis thaliana wild type （Col） and the low-seed-oil mutant wrinkled1-3. We observed that the oil body development in the embryos of Col is similar to that of B. napus cv. Topas, and that the size of the oil bodies was obviously smaller in the embryos of wrinkled1-3. Our results suggest that the oil body biogenesis might be coupled with the embryo chloroplast.

为比较不同保存方式对鸡减蛋综合征灭活抗原的影响,采用禽腺病毒京911株(CVCC AV70)经尿囊腔接种易感鸭胚,收获感染鸭胚液,经β-丙内酯灭活后,对该抗原的保存条件及其稳定性等方面进行优化。冻干抗原与未冻干抗原在相同温度下,冻干抗原HA效价下降较慢。冻干抗原在2~8℃和-15℃以下保存,HA效价没有明显差异。因此,生产的鸡减蛋综合征灭活抗原要在冻干后保存在2~8℃最佳。保存条件的优化不仅可以减少经济损失,而且还有助于更好的控制禽腺病毒疫情的暴发。

社会数据的空间化是现代地图制图学研究的主要内容之一。本文提出了区域统计指标的概念并将其分为区域平均指标与区域总量指标两种类型,成功地将网格单元面积权重内插(GCAW I)法引入到区域统计指标的空间化工作中,应用GCAW I法实现了新沂市耕地标准亩指标的空间化表达,结果表明:运用GCAW I法进行区域统计指标的空间化不仅可以很好地避免传统方法的同一区域均匀分布、不同区域突变分布的缺点,而且经kriging插值后的地图很好地符合区域统计指标空间分布的特点,生成的3维可视化地图更加切合实际。

With accumulating evidence of transcatheter aortic valve replacement(TAVR)worldwide,it is gradually realized that patients being treated are different across different coun-tries,including but not limited to their age,habitus,disease etiology,aortic valve morphology,and sizes of structures.[1]In China,the average age of TAVR patients is around 5 years younger than industrialized countries,[2]making Chinese patients a good predictive sample of what the industrialized countries might see in TAVR screening in the near future due to the expansion of this technique to younger patients,but anatomical features appreciated from multi-slice computed tomography(MSCT)in the Chinese patient population have not been well demonstrated.

现有时间序列夜间灯光影像校正方法只适用于灯光亮度持续增长情况,对于城市收缩地区夜间灯光亮度的校正效果不佳。该文提出一种面向城市收缩地区的DMSP/OLS夜间灯光影像多年连续校正方法(Inter-annual Series Correction for Shrinking Area,ISCSA),包括多传感器相互校正、多传感器年内融合、时间序列可比较校正和连续校正四方面,以东三省1992-2013年34期DMSP/OLS夜间灯光影像进行验证,并分析其与社会经济数据的相关性。结果显示:该方法校正后的夜间灯光影像不仅能反映东三省长时序的城市扩张现象,还能体现短时间的城市收缩现象;校正后的夜间灯光亮度与GDP和人口的相关性相比原始影像数据和传统连续校正方法均有一定提升,能更合理地反映东三省社会经济要素的发展差异。

We discuss the fundamental solution for m-th powers of the sub-Laplacian on the Heisenberg group. We use the representation theory of the Heisenberg group to analyze the associated m-th powers of the sub-Laplacian and to construct its fundamental solution. Besides, the series representation of the fundamental solution for square of the sub-Laplacian on the Heisenberg group is given and we also get the closed form of the fundamental solution for square of the sub-Laplacian on the Heisenberg group with dimension n = 2, 3, 4.
