MORTUARY ART IN THE NORTHERN ZHOU CHINA (557-581 CE): VISUALIZATION OF CLASS, ROLE, AND CULTURAL IDENTITY
Full text linkThe period of Six Dynasties (221-581CE) has traditionally been thought of as a time when "the Five Barbarians brought disorder to China." During this period, present-day Northern China was ruled by non-Han leaders, including the Xianbei, a pastoral people from China's northern frontier who founded the Northern Zhou Dynasty. In addition, Chinese historical texts from the Six Dynasties refer to "merchant barbarians" generally assumed to be Sogdians, who lived in oasis states in Central Asia in present-day Uzbekistan and came to China across the Silk Road. Most scholarship has assumed that the period of Northern Zhou ruled by non-Chinese leaders was "sinicized," and the adoption of Chinese features in burial and artifacts in foreigners' tombs is evidence of that acculturation process. This dissertation, however, uses newly excavated materials from tombs dated to the Northern Zhou period, including the tombs of Xianbei leaders, Xianbei and Chinese generals, and Sogdian merchants, and proposes that visual arts and mortuary ritual played a role in creating and/or maintaining multiple sociopolitical and cultural identities for these residents of Northern Zhou. The theorization of power, agency, and cultural identity in recent publications has helped me analyze the processes involved in the construction of individual identity, group boundaries, and the interrelationships between socio-cultural groups. Theories of agency have helped me focus on choices made by different social and occupational groups. This dissertation has explored how the patterns of use of mortuary objects documented multiple identities for these three classes listed above with specific ethnic backgrounds: the sovereigns who were Xianbei; the military class of Xianbei and Han-Chinese; and the merchant class of Sogdians. I have discussed how aspects of political, military, and merchant life in the Northern Zhou period created a setting that contributed to multiple roles and identities in each group. My study has demonstrated the construction of multiple identities among elites and how they consistently distinguished themselves from other members of society. This dissertation will be the first contextual analysis focused on the visualization of class, social roles and cultural affiliation by examining mortuary art in the Northern Zhou
Intrinsic Disorder and Semi-disorder Prediction by SPINE-D
No full textOver the past decade, it has become evident that a large proportion of proteins contain intrinsically disordered regions, which play important roles in pivotal cellular functions. Many computational tools have been developed with the aim of identifying the level and location of disorder within a protein. In this chapter, we describe a neural network based technique called SPINE-D that employs a unique three-state design and can accurately capture disordered residues in both short and long disordered regions. SPINE-D was trained on a large database of 4229 non-redundant proteins, and yielded an AUC of 0.86 on a cross-validation test and 0.89 on an independent test. SPINE-D can also detect a semi-disordered state that is associated with induced folders and aggregation-prone regions in disordered proteins and weakly stable or locally unfolded regions in structured proteins. We implement an online web service and an offline stand-alone program for SPINE-D, they are freely available at http://sparks-lab.org/SPINE-D/. We then walk you through how to use the online and offline SPINE-D in making disorder predictions, and examine the disorder and semi-disorder prediction in a case study on the p53 protein.No Full Tex
