| 1 | Context Information and Fragments Based Cross-Domain Word Segmentation显示文摘A new joint decoding strategy that combines the character-based and word-based conditional random field model is proposed.In this segmentation framework,fragments are used to generate candidate Out-of-Vocabularies(OOVs).After the initial segmentation,the segmentation fragments are divided into two classes as 'combination'(combining several fragments as an unknown word) and 'segregation'(segregating to some words).So,more OOVs can be recalled.Moreover,for the characteristics of the cross-domain segmentation,context information is reasonably used to guide Chinese Word Segmentation(CWS).This method is proved to be effective through several experiments on the test data from Sighan Bakeoffs 2007 and Bakeoffs 2010.The rates of OOV recall obtain better performance and the overall segmentation performances achieve a good effect. | Huang Degen Tong Deqin | 2012 | China Communications2012，9，3： | 8 |

| 3 | The adaptive strategies of yaks to live in the Asian highlands显示文摘The yak(Bos grunniens),an indigenous herbivore raised at altitudes between 3,000 and 5,000 m above sea level,is closely linked to more than 40 ethnic communities and plays a vital role in the ecological stability,livelihood security,socio-economic development,and ethnic cultural traditions in the Asian highlands.They provide the highlanders with meat,milk,fibres,leather and dung(fuel).They are also used as pack animals to transport goods,for travel and ploughing,and are important in many religious and traditional ceremonies.The Asian highlands are known for an extremely,harsh environment,namely low air temperature and oxygen content and high ultraviolet light and winds.Pasture availability fluctuates greatly,with sparse pasture of poor quality over the long seven-month cold winter.After longterm natural and artificial selections,yaks have adapted excellently to the harsh conditions:1)by genomics,with positively selected genes involved in hypoxia response and energy metabolism;2)anatomically,including a short tongue with a weak sense of taste,and large lung and heart;3)physiologically,by insensitivity to hypoxic pulmonary vasoconstriction,maintaining foetal haemoglobin throughout life,and low heart rate and heat production in the cold season;4)behaviourlly,by efficient grazing and selecting forbs with high nutritional contents;5)by low nitrogen and energy requirements for maintenance and low methane emission and nitrogen excretion,namely,‘Low-Carbon’and‘Nitrogen-Saving’traits;6)by harboring unique rumen microbiota with a distinct maturation pattern,that has coevolved with host metabolism.This review aims to provide an overview of the comprehensive adaptive strategies of the yak to the severe conditions of the highlands.A better understanding of these strategies that yaks employ to adapt to the harsh environment could be used in improving their production,breeding and management,and gaining benefits in ecosystem service and a more resilient livelihood to climate change in the Asian highlands. | Xiaoping Jing Luming Ding Jianwei Zhou Xiaodan Huang Allan Degen Ruijun Long | 2022 | Animal Nutrition2022，，2： | 2 |

| 6 | An experimental study on the influences of wind erosion on water erosion显示文摘In semi-arid regions, complex erosion resulted from a combination of wind and water actions has led to a massive soil loss and a comprehensive understanding of its mechanism is the first step toward prevention of the erosion. However, the mutual influences between wind erosion and water erosion have not been fully understood. This research used a wind tunnel and two rainfall simulators and simulated two rounds of alternations between wind erosion and water erosion(i.e., 1^(st) wind erosion–1^(st) water erosion and 2^(nd) wind erosion–2^(nd) water erosion) on three slopes(5°, 10°, and 15°) with six wind speeds(0, 9, 11, 13, 15, and 20 m/s) and five rainfall intensities(0, 30, 45, 60, and 75 mm/h). The objective was to analyze the influences of wind erosion on succeeding water erosion. Results showed that the effects of wind erosion on water erosion were not the same in the two rounds of tests. In the 1^(st) round of tests, wind erosion first restrained and then intensified water erosion mostly because the blocking effect of wind-sculpted micro-topography on surface flow was weakened with the increase in slope. In the 2^(nd) round of tests, wind erosion intensified water erosion on beds with no rills at gentle slopes and low rainfall intensities or with large-size rills at steep slopes and high rainfall intensities. Wind erosion restrained water erosion on beds with small rills at moderate slopes and moderate rainfall intensities. The effects were mainly related to the fine grain layer, rills and slope of the original bed in the 2^(nd) round of tests. The findings can deepen our understanding of complex erosion resulted from a combination of wind and water actions and provide scientific references to regional soil and water conservation. | YANG Huimin GAO Yuan LIN Degen ZOU Xueyong WANG Jing'ai SHI Peijun | 2017 | Journal of Arid Land2017，9，4： | 2 |
