Machine learning-aided atomic structure identification of interfacial ionic hydrates from AFM imagesOA

Relevant to broad applied fields and natural processes,interfacial ionic hydrates have been widely studied by using ultrahigh-resolution atomic force microscopy(AFM).However,the complex relationship between the AFM signal and the investigated system makes it difficult to determine the atomic structure of such a complex system from AFM images alone.Using machine learning,we achieved precise identification of the atomic structures of interfacial water/ionic hydrates based on AFM images,including t...     

PRIVATELY-OWNED MUSEUMS IN BEIJING

Private collection in Beijing dates back to 800 years and saw its heydays in the early 20th century. The long history of private collection has enabled the city to take the leading place in China＇s collection field. Over the past two decades, in particular, collection has gained increasing popularity among ordinary people in Beijing and some have even run privately-owned museums.     

Cultural Flavors of Tianjin

The charm of the city of Tianjin is manifested not only in its modem high-rise buildings, but also in its unique culture and traditions. Over the past several hundred years, a distinctive cultural style has developed in this port city in north China.[第一段]     

Tianjin＇s Spring Festival Traditions Hog Global Spotlight

The city of Tianjin, with its history dating back to 600 years, sees a variety of folk arts and traditions. In recent years, tremendous efforts have been made by the government and private organizations alike to restore and revitalize those valuable folldores, such as revamping the Curio Street, building museums on folk arts and traditions, rebuilding the Drum Tower and more. Now during the Spring Festival （Chinese lunar New Year）, the May First seven-day break and the National Day holiday, showcases of time-honored traditions and folk arts, such as diabolo spinning, sugar painting making, flour doll maMng and tea soup shows, are presented in the Curio Street and the Drum Tower shopping street to attract tourists from home and abroad. The Curio Street is also classified as four-star national-level tourist destination. According to incomplete statistics, during the 2007 Spring Festival, the city of Tianjin received dozens of tourist groups from the US, Germany, France, lapan and more.[第一段]     

Variability Theory and Its Enlightenment on the Treatment of Errors

In SLA, the learners’ language as interlanguage has been widely recognized and discussed among teachers and linguists.Various models have been established to explain the phenomenon of errors in second language learning including the Variability Theory in question. This paper makes an attempt to review the Variability Theory and its distinct attitude and solution to the socalled errors.     

图书在版编目（CIP）数据刍议

图书在版编目是已被发达国家广泛采用的一种图书编目方式。它是在图书出版过程中，由集中编目机构依据一定的标准编制出书目数据，印制在图书主书名页背面，使得图书本身和它的书目资料能同时为发行单位、图书馆和读者所利用。在我国实施图书在版编目，是促使我国各类图书目录的编制工作实现标准化、自动化和社会化的重要条件，是文献目录工作向现代化发展的必然产物。１图书在版编目（ＣＩＰ）数据的基本款目我国图书在版编目（ＣＩＰ）数据的基本款目，是按《普通图书著录规则》著录、《中国图书馆图书分类法》分类、《文献主题标引规则》…     

Mass spectrometry-based protein-protein interaction techniques and their applications in studies of DNA damage repair

Proteins are major functional units that are tightly connected to form complex and dynamic networks.These networks enable cells and organisms to operate properly and respond efficiently to environmental cues.Over the past decades,many biochemical methods have been developed to search for protein-binding partners in order to understand how protein networks are constructed and connected.At the same time,rapid development in proteomics and mass spectrometry(MS)techniques makes it possible to identify interacting proteins and build comprehensive protein-protein interaction networks.The resulting interactomes and networks have proven informative in the investigation of biological functions,such as in the field of DNA damage repair.In recent years,a number of proteins involved in DNA damage response and DNA repair pathways have been uncovered with MS-based protein-protein interaction studies.As the technologies for enriching associated proteins and MS become more sophisticated,the studies of protein-protein interactions are entering a new era.In this review,we summarize the strategies and recent developments for exploring protein-protein interaction.In addition,we discuss the application of these tools in the investigation of protein-protein interaction networks involved in DNA damage response and DNA repair.
