| 2 | Application of isolation forest to extract multivariate anomalies from geochemical exploration data显示文摘Constructing a statistical model that best fits the background is a key step in geochemical anomaly identification. But the model is hard to be constructed in situations where the sample population has unknown and/or complex distribution. Isolation forest is an outlier detection approach that explicitly isolates anomaly samples rather than models the population distribution. It can extract multivariate anomalies from huge-sized high-dimensional data with unknown population distribution. For this reason,we tentatively applied the method to identify multivariate anomalies from the stream sediment survey data of the Lalingzaohuo district,an area with a complex geological setting,in Qinghai Province in China. The performance of the isolation forest algorithm in anomaly identification was compared with that of a continuous restricted Boltzmann machine. The results show that the isolation forest model performs superiorly to the continuous restricted Boltzmann machine in multivariate anomaly identification in terms of receiver operating characteristic curve,area under the curve,and data-processing efficiency. The anomalies identified by the isolation forest model occupy 19% of the study area and contain 82% of the known mineral deposits,whereas the anomalies identified by the continuous restricted Boltzmann machine occupy 35% of the study area and contain 88% of the known mineral deposits. It takes 4. 07 and 279. 36 seconds respectively handling the dataset using the two models. Therefore,isolation forest is a useful anomaly detection method that can quickly extract multivariate anomalies from geochemical exploration data. | WU Wei CHEN Yongliang | 2018 | Global Geology2018,21,1: | 9 |
| 3 | Guiding T lymphopoiesis from pluripotent stem cells by defined transcription factors显示文摘Achievement of immunocompetent and therapeutic T lymphopoiesis from pluripotent stem cells(PSCs)is a central aim in T cell regenerative medicine.To date,preferentially reconstituting T lymphopoiesis in vivo from PSCs remains a practical challenge.Here we documented that synergistic and transient expression of Runx1 and Hoxa9 restricted in the time window of endothelial-to-hematopoietic transition and hematopoietic maturation stages in a PSC differentiation scheme(iR9-PSC)in vitro induced preferential generation of engraftable hematopoietic progenitors capable of homing to thymus and developing into mature T cells in primary and secondary immunodeficient recipients.Single-cell transcriptome and functional analyses illustrated the cellular trajectory of T lineage induction from PSCs,unveiling the T-lineage specification determined at as early as hemogenic endothelial cell stage and identifying the bona fide pre-thymic progenitors.The induced T cells distributed normally in central and peripheral lymphoid organs and exhibited abundant TCRαβrepertoire.The regenerative T lymphopoiesis restored immune surveillance in immunodeficient mice.Furthermore,gene-edited iR9-PSCs produced tumor-specific T cells in vivo that effectively eradicated tumor cells.This study provides insight into universal generation of functional and therapeutic T cells from the unlimited and editable PSC source. | Rongqun Guo Fangxiao Hu Qitong Weng Cui Lv Hongling Wu Lijuan Liu Zongcheng Li Yang Zeng Zhijie Bai Mengyun Zhang Yuting Liu Xiaofei Liu Chengxiang Xia Tongjie Wang Peiqing Zhou Kaitao Wang Yong Dong Yuxuan Luo Xiangzhong Zhang Yuxian Guan Yang Geng Juan Du Yangqiu Li Yu Lan Jiekai Chen Bing Liu Jinyong Wang | 2020 | Cell Research2020,30,1: | 7 |
| 4 | Planetary Stationary Waves in the Atmosphere Part I: Orographic Stationary Waves显示文摘It is proposed that the orographic stationary waves are required by long-term balance of momentum in the atmosphere with zonally asymmetric orographic forcing. This hypothesis may be confirmed successfully with the theoretical model of geostrophic waves. In the Part I, we will explain the observed phase distributions of orographic stationary waves at middle and high latitudes of the Northern Hemisphere, according to the long-term balance of zonal momentum over the stationary orographic forcing. It is revealed that the geographic distribution of stationary waves depends not only on local topgraphy but also on mean circulation fields and angular momentum flux in the atmosphere. So these waves cannot be simulated by the models in a restricted area. | Yong. L. McHall | 1991 | Advances in Atmospheric Sciences1991,8,2: | 7 |
| 5 | DISTRIBUTION AND ABUNDANCE OF EGGS AND LARVAE OF ANTARCTIC KRILL(ENPHAUSUA SUPERBADANA)IN ANTARCTIC PENINSULA AREA显示文摘During the First Chinese Antarctic Expedition zooplankton samples were collected at each of the oceanography stations in the waters around South Sheltland Islands (S. S. Is.) and in the northern part of the Bellinshausen Sea from 20 January to 12 February, 1985 by vertical tows of an 80 cm diameter conical net from 200 m to surface. Two deep tows with a closing net. were performed in slope water north of S.S. Is, and in the basin of Bransfield Strait. Eggs and larvae of Euphatisia superba Dana in zooplankton samples were identified and counted.There were four records of eggs from 27 stations.

| 7 | The First National Prevalence of Autism Spectrum Disorder in China显示文摘Autism spectrum disorder (ASD) is a complex developmental disability characterized by impaired social interaction and communication,restricted interests,and stereotypical behaviors [1,2].In addition to these core diagnostic features,children with ASD frequently present with a host of associated behavioral issues,such as intellectual disability and epilepsy,as well as feeding and sleep problems.The prevalence of ASD in the United States is about 1/59,with a significantly higher proportion in males [3].Therefore,ASD is no longer a rare disorder. | Zi Chao Zhang Junhai Han | 2020 | Neuroscience Bulletin2020,36,9: | 5 |
| 8 | Orbit design for the Laser Interferometer Space Antenna (LISA)显示文摘The Laser Interferometer Space Antenna (LISA) is a joint ESA-NASA mission for detecting low-frequency gravitational waves in the frequency range from 0.1 mHz to 1 Hz, by using accurate laser interferometry between three spacecrafts, which will be launched around 2018 and one year later reach their operational orbits around the Sun. In order to operate successfully, it is crucial for the constellation of the three spacecrafts to have extremely high stability. Based on the study of operational orbits for a 2015 launch, we design the operational orbits of beginning epoch on 2019-03-01, and introduce the method of orbit design and optimization. We design the orbits of the transfer from Earth to the operational orbits, including launch phase and separation phase; furthermore, the relationship between energy requirement and flight time of these two orbit phases is investigated. Finally, an example of the whole orbit design is presented. | Gerhard HEINZEL Albrecht RDIGER | 2010 | Science China(Physics,Mechanics & Astronomy)2010,53,1: | 4 |
| 9 | Fiducial intervals of restricted parameters and their applications显示文摘In practice, the unknown parameters are often restricted. This paper provides a general method for constructing the fiducial intervals of the restricted parameters. Applying the general method, the fiducial intervals are constructed for the location (scale)parameters and the difference (ratio) of two locations (scales) in a location (scale) family of distributions. The frequency properties of these intervals are verified. For a variance components model, the fiducial intervals for the three parameters of common interest are obtained. Their frequency properties are investigated theoretically and computationally. | LI Xinmin, LI Guoying & XU Xingzhong College of Mathematics and Information Sciences, Shandong University of Technology, Zibo 255049, China Academy of Mathematics and System Sciences, Chinese Academy of Sciences, Beijing 100800, China Department of Mathematics, Beijing Institute of Technology, Beijing 100801, China | 2005 | Science China Mathematics2005,48,11: | 4 |

| 12 | Compressed Sensing of IR-UWB Wireless Sensor Network Data Based on Two-Dimensional Measurements显示文摘A novel Compressed sensing(CS) method based on two-dimensional measurements is proposed that can be effectively utilized in Impulse radio ultra-wideband wireless sensor networks(IR-UWB WSNs) to significantly reduce the energy consumption and sampling rate in sensor data transferring. We start by establishing the CS measurement model by taking both spatial and temporal correlations of Wireless sensor network(WSN) data into account. Since our model incorporates a new type of measurement matrix: the block quasi-Toeplitz structured matrix, we derive the Restricted isometry property(RIP)of the block quasi-Toeplitz structured matrix to ensure the performance of the two-dimensional recovery of WSNs data. We substantiate our mathematical analysis by numerical examples in the context of ideal spares vector and real WSN data, and results demonstrate that the approach achieves significantly saving of energy and sampling rate with small reconstruction error. | WANG Kai LIU Yulin WAN Qun JING Xiaojun | 2015 | Chinese Journal of Electronics2015,24,3: | 3 |
| 13 | Ethnobotanical inventory and medicinal uses of some important woody plant species of Kotli,Azad Kashmir,Pakistan显示文摘Objective:To document ethnobotanical informations of useful woody plant species in the region of Kotli,Azad Kashmir.Methods:An ethnobotanical survey was conducted in Kotli.Data were collected by interview and semi structured questionnaire from selected local informants and traditional practitioners as well as by field assessment.Results:The present study documented the etnobotanical uses of 33 woody plant species.Most of the species have been used for dual purpose.Only 5 species are used for one purpose.Study revealed all species have medicinal value,among which 21 were used as fuel wood species,16 as fodder species,4 as timber wood species,12 as edible fruit species,6 as fence or hedge plant,7 as ornamental species and 12 species had other uses.Conclusions:Medicinal plants are still widely used for health care by locals of Kotli.Some species of woodlands seem to be vulnerable to overcollection and deforestation.As the young generation is diverted toward allelopathic medicines,ethnobotanical knowledges of important medicinal plants are restricted to the old people only.It is suggested to close the forest of district Kotli for next two to three decades for the conservation of plant biodiversity. | Muhammad Shoaib Amjad Muhammad Arshad | 2014 | Asian Pacific Journal of Tropical Biomedicine2014,4,12: | 3 |
