| 1 | Development of powdery mildew resistant derivatives of wheat variety Fielder for use in genetic transformation显示文摘Genetic transformation is widely used to improve target traits and to study gene function in wheat.However,transformation efficiency depends on the physiological status of the recipient genotype and that is affected by several factors including powdery mildew(PM)infection.The widely used recipient variety Fielder is very susceptible to PM.Therefore,it would be beneficial to develop PM resistant derivatives with high regeneration ability for use in genetic transformation.In the present study PM resistant lines CB037 and Pm97033 carrying genes Pm21 and PmV,respectively,were backcrossed to Fielder with selection for PM resistance.Five lines,NT89,NT90,NT154,and WT48 with Pm21 and line FL347 with PmV were developed,identified by molecular markers and genomic in situ hybridization(GISH)or fluorescent in situ hybridization(FISH),and further subjected to detailed assessment of agronomic traits and regeneration ability following genetic transformation capacity.Lines FL347,WT48,NT89 and NT154 assessed as being equal to,or superior,to Fielder in regeneration and transformation ability are recommended as suitable materials for the replacement of Fielder for wheat gene transfer and genome editing study. | Xiaona Liang Xiaomin Bie Yuliang Qiu Ke Wang Zujun Yang Yuqi Jia Zhiying Xu Mei Yu Lipu Du Zhishan Lin Xingguo Ye | 2023 | The Crop Journal2023，11，2： | 2 |
| 2 | C-HMAX: Artificial Cognitive Model Inspired by the Color Vision Mechanism of the Human Brain显示文摘Artificial cognitive models and computational neuroscience methods have garnered great interest from both neurologist and leading analysts in recent years. Among the cognitive models, HMAX has been widely used in computer vision systems for its robustness shape and texture features inspired by the ventral stream of the human brain. This work presents a Color-HMAX (C-HMAX) model based on the HMAX model which imitates the color vision mechanism of the human brain that the HMAX model does not include. C-HMAX is then applied to the German Traffic Sign Recognition Benchmark (GTSRB) which has 43 categories and 51 840 sample traffic signs with an accuracy of 98.41%, higher than most other models including linear discriminant analysis and multi-scale convolutional neural network. | Bo Yang Lipu Zhou Zhidong Deng | 2013 | Tsinghua Science and Technology2013，18，1： | 1 |

| 4 | Crustal density structure of the southern segment of the Liaocheng-Lankao fault, China显示文摘The 1:200,000 middle-large scale Bouguer gravity anomaly data covering the southern segment of the Liaocheng-Lankao fault(SLLF)and its vicinity are analyzed with two methods.First,the Bouguer gravity anomaly data are decomposed by two-dimensional(2 D)wavelet to make the family of multi-scale modes correspond with density structure at different depths.Second,a two and half dimension(2.5 D)human-computer interaction inversion of the Bouguer gravity anomaly data are conducted with the constraints provided by two deep seismic sounding profiles(DSS1 and DSS2)crossing the study area to get the crustal density profiles.Based on the integrated study,we can draw the following conclusions:1)SLLF appears to be a deep fault with almost vertical dipping and rooted into the uppermost mantle;2)In the middle to upper crust SLLF shows an clear turning patterns and segmentation features;3)In the study area the epicentral distributions of the precisely re-located small earthquakes and the historical large earthquakes have a good correspondence with the turning patterns and segmentation features of SLLF;and 4)The results of the horizontal slices from 2 D wavelet decomposition show that there are significant differences in the density structure on the two sides of the fault.A well-defined concave structure with low density exists in the upper crust of the Dongming Depression on the west side of the fault,with the concave center being estimated at a depth of about 8 km.In contrast,the upper crust on the east side presents a relative thinner pattern in depth with a bit higher density.Meanwhile,the low-density structure in the middle crust underneath the fault is presumably caused by the uplift of the upper mantle materials and their intrusion along the deep rupture system.This paper clarified the inconsistency of fault system and epicenters of small earthquakes from upper to lower crust.The results indicated that the fault system plays an important governing role to the seismicity in this area. | Lei Jiang Lanbo Liu Zhiping Xu Xiaoguo Deng Lipu Yang Wei Xiong Shunqiang Xu | 2019 | Geodesy and Geodynamics2019，10，5： | 0 |
