A study of the modern Chinese novel, Gao Yubao and its author Gao Yubao
No full textGao Yubao, a soldier in the Chinese People's Liberation Army, was nearly illiterate when he began to write his autobiographical novel, Gao Yubao, in 1949. The PLA's literary branch helped him finish the novel and after its publication Gao and his struggle to become literate by writing a novel served as an inspiration for others striving for education. Gao Yubao was republished several times up until as late as the 1970's and each time it was republished it was revised. This paper traces the history of the novel Gao Yubao and its author with special attention being given to comparing the changes made in the various editions of the novel. The conflicts between amateurism and professionalism and between fact and romanticization and those conflicts inherent in the constant revisings demanded of an already revised work are shown to be unresolvable because of the nature of contemporary Chinese literature.Arts, Faculty ofAsian Studies, Department ofGraduat
Accommodating Nomocharis in Lilium (Liliaceae)
No full textControversy regarding the status of the genus Nomocharis Franchet (1889: 113) has been undergoing since its recognition by Franchet (1889). Recent molecular studies (Nishikawa et al. 1999, Hayashi & Kawano 2000, Nishikawa et al. 2001, Ronsted et al. 2005, Peruzzi et al. 2009) have resolved Nomocharis as being nested within Lilium Linaeus (1753: 302). Results of our own previous studies (Gao et al. 2012, Gao et al. 2013a, Gao et al. 2013b), with expanded sampling of species of Nomocharis have been congruent with those of previous studies by others. Thus recognition of Nomocharis would render Lilium paraphyletic. We prefer to recognize a monophyletic Lilium here, although paraphyletic groups are sometimes advocated in literature (e.g., Brummitt, 2014; Ehrendorfer & Barfuss, 2014; George, 2014; Horandl, 2014; Stuessy & Horandl, 2014; Stuessy et al., 2014). Most recently, we proposed that the morphological divergence between Nomocharis and Lilium was the result of habitat specialization (Gao et al. 2015). The extensive introgression caused by hybridization within Lilium and Nomocharis (Gao et al. 2013a, 2015) supports a single-genus concept

Adversarial Attacks against the Perception System of Autonomous Vehicles
No full textThe rapid advancement in autonomous driving technology underscores the importance of studying the fragility of perception systems in autonomous vehicles, particularly due to their profound impact on public transportation safety. These systems are of paramount importance due to their direct impact on the lives of passengers and pedestrians. Additionally, their reliability can be easily compromised given the complexity and unpredictability of driving environments. However, current research and existing regulations often fail to adequately address the adversarial robustness of autonomous vehicle perception systems. This thesis delves into the adversarial robustness of camera-based perception systems of autonomous vehicles. Our research concentrates on developing and implementing evasion attacks that use black-box gradient estimation, as well as physical attacks in traffic sign detection and classification systems. Our findings indicate that even minor perturbations can impact the accuracy of these systems, leading to detection and classification errors. This finding highlights a critical vulnerability in the perception system's robustness against adversarial attacks. Moreover, the study extends to assess the transferability of adversarial examples across diverse perception models. Our results also expose significant gaps in the current regulatory frameworks of autonomous vehicles, necessitating the establishment of more rigorous and comprehensive safety standards.https://github.com/yuxing-gao/adversarial-attack-traffic-sign-detectionMechanical Engineering | Systems and Contro
Miridiba lamellata Gao & Fang 2019

(2019) described <i>Miridiba</i> (<i>Pledina</i>) <i>lamellata</i> based on the male holotype only, deposited in the collection of Shenyang Agricultural University of China. This species was included in the subgenus <i>Pledina</i> based on the antenna 10-segmented (Gao <i>et al</i>. 2019), without specifying the features of <i>M. lamellata</i> shared with <i>M. sinensis</i> (type species of <i>Pledina</i>), which would justify considering this new species in the subgenus. We have studied herein <i>M. sinensis</i> that, together with <i>M. pseudosinensis</i>, <i>M. axanensis</i> and <i>M. quasisinensis</i>, constitute the morphotype V “ <i>Sinensis</i> ”, candidate to be subgenus <i>Pledina</i> (see Discussion and Conclusions), and we have not found enough similarities to consider <i>M. lamellata</i> belonging to morphotype V “ <i>Sinensis</i> ”. The antenna 10-segmented, the only character considered by Gao <i>et al</i>. (2019) to classify this new species in the subgenus <i>Pledina</i>, is shared by many other <i>Miridiba</i> species, those included herein in morphotypes II to VIII, and even by many other species of <i>Holotrichia</i>. Therefore, this character is not enough to consider <i>M. lamellata</i> belonging to <i>Pledina</i>. In addition to that, this new species can be separated from <i>M. sinensis</i> by the branches of parameres and setae on mentum and pygidium (Gao <i>et al</i>. 2019: figs 9, 14–17), both species are so different that <i>M. lamellata</i> cannot be considered belonging to <i>Pledina</i>. Likewise, the mentum and labrum of <i>M. lamellata</i> differ from those of <i>Miridiba</i>. Unlike <i>Miridiba</i>, the new species has the mentum with sparse pubescence on the anterior part, and the labrum more strongly depressed at its ventral part than at dorsal one (Gao <i>et al</i>. 2019: figs 5, 9). Therefore, the second author of this paper has doubts about inclusion of <i>M. lamellata</i> in the genus <i>Miridiba</i>. However, taking into account that the first author of this paper is one of the authors of the species and the second author has not studied it, <i>M. lamellata</i> is considered a species incertae sedis of <i>Miridiba</i>.</p> Distribution <p>China (Guizhou).</p>Published as part of <i>Gao, Chuan-bu & Coca-Abia, María Milagro, 2021, Revision of the genus Miridiba Reitter, 1902 (Coleoptera, Scarabaeidae, Melolonthinae): genital morphotypes and new taxonomic data, pp. 1-94 in European Journal of Taxonomy 749</i> on pages 82-83, DOI: 10.5852/ejt.2021.749.1355, <a href="http://zenodo.org/record/4770293">http://zenodo.org/record/4770293</a>
To comply or not to comply: understanding the discretion in reporting public float and SEC regulations
No full textThis paper documents how firms exercise discretion in defining affiliates and reporting public float in response to SEC regulations. I find that firms with higher expected compliance costs under Section 404 of the Sarbanes-Oxley Act (SOX) of 2002 tend to classify more shares as affiliated and report lower public float. In contrast, firms issuing seasoned equity are less likely to underreport public float, possibly due to favorable regulatory treatment for large issuers. These incentives are weakened when future regulatory changes render float less important.Peer reviewe

Aesthetics in Gao\u27s Soul Mountain
No full textIn her article Aesthetics in Gao\u27s Soul Mountain Mabel Lee analyses Nobel Laureate 2000 Xingjian Gao\u27s aesthetics. Transnational conglomerates today control the book industry from publishing house to bookshop and through aggressive market strategies they exert considerable influence on readers. Nonetheless, there are writers who refuse to capitulate to market demands and seek only to actualize their aesthetic ideas in the creation of literary texts. One such writer is Gao, author of the novel Soul Mountain. Lee posits that Gao\u27s aesthetics is founded on the close interrogation of both Chinese and European models and practices and explores specific aspects of Gao\u27s aesthetics and how these are embedded in his novel Soul Mountain. In an Appendix the article includes lists of Gao\u27s works in Chinese and English, as well as a list of studies on his oeuvre
Investigation of Lagrangian coherent structures in a wake-induced boundary layer transition
No full textThe evolution of coherent structures in a flat plate boundary layer transition induced by the cylinder wake is investigated using the particle image velocimetry (PIV) technique. The finite-time Lyapunov exponent (FTLE), which characterizes the amount of stretching about the flow trajectory, is used to extract the Lagrangian coherent structures. It is revealed that secondary vortex is induced by the cylinder wake vortices in the near wall region,which would evolve into hairpin vortex as it convects downstream. The subsequent evolvement of the hairpin vortex, characterized by the regeneration of offspring hairpin vortex upstream of it, leads to the appearance of the hairpin packet and the boundary layer finally reaches a turbulent state
