Optimal beaconing control for epidemic routing in delay tolerant networks
No full textOwing to the uncertainty of transmission opportunities between mobile nodes, the routing in delay-tolerant networks (DTNs) exploits the mechanism of opportunistic forwarding. Energy-efficient algorithms and policies for DTN are crucial to maximizing the message delivery probability while reducing the delivery cost. In this contribution, we investigate the problem of energy-efficient optimal beaconing control in a DTN. We model the message dissemination under variable beaconing rate with a continuous-time Markov model. Based on this model, we then formulate the optimization problem of the optimal beaconing control for epidemic routing and obtain the optimal threshold policy from the solution of this optimization problem. Furthermore, through extensive numerical results, we demonstrate that the proposed optimal threshold policy significantly outperforms the static policy with constant beaconing rate in terms of system energy consumption savings
Analysis of Fu Caiyun's “dissolute beauty” and Zeng Pu's “struggle between two minds” ：a study based on Bakhtin's polyphony in perspective
No full textFu Caiyun, the Reckless Beauty ””, is the most complex artistic character created by Zeng Pu in Sinful Sea F l owers, which has received mixed reviews from academics. The reason for the controversy is the obvious polyphony of Sinful Sea Flowers. Zeng Pu does not narrate Fu Caiyun's story with the absolute authority of the author, Fu Caiyun has a subjective position in the novel , and she expresses her own voice and forms a double subject dialogue with the author Zeng Pu's voice. Thus Fu Caiyun becomes a Reckless beauty with polyphonic characteristics in Sinful Sea Flowers. The polyphony of Reckless Beauty is the result of Zeng Pu's two minds struggle with the historical and cultural context in which he lives . The blending of new and old identities, the cultural dialogue between Chinese and Western influences are internal conflicts that impacted Zeng Pu' s rewriting of Fu Caiyun, rendering her character with a polyphonic nature of multiple voices. The text is filled with dialogues between Zeng Pu's self ””' and the other Fu Caiyun. Essentially, this represents a double voiced polyphony of Zeng Pu's consci o us and unconscious minds, embodying the struggle between two minds within his internal subjective world
Analysis of Fu Caiyun's “Dissolute Beauty” and Zeng Pu's “Struggle Between Two Minds” ：a study based on Bakhtin's Polyphony in perspective
No full textFu Caiyun, the “Reckless Beauty”, is the most complex artistic character created
by Zeng Pu in Sinful Sea Flowers, which has received mixed reviews from academics.
The reason for the controversy is the obvious polyphony of Sinful Sea Flowers. Zeng Pu
does not narrate Fu Caiyun's story with the absolute authority of the author, Fu Caiyun
has a subjective position in the novel, and she expresses her own voice and forms a
double-subject dialogue with the author Zeng Pu's voice. Thus Fu Caiyun becomes a
“Reckless beauty” with polyphonic characteristics in Sinful Sea Flowers. The
polyphony of “Reckless Beauty” is the result of Zeng Pu's “two minds struggle” with
the historical and cultural context in which he lives. The blending of “new” and “old”
identities, the cultural dialogue between “Chinese” and “Western” influences are
internal conflicts that impacted Zeng Pu's rewriting of Fu Caiyun, rendering her
character with a polyphonic nature of multiple voices. The text is filled with dialogues
between Zeng Pu's “self”' and the “other” Fu Caiyun. Essentially, this represents a
double-voiced polyphony of Zeng Pu's conscious and unconscious minds, embodying
the “struggle between two minds” within his internal subjective world
The literary making of a Uyghur feminist : Identity and ethics in Banu's Redemption
No full textBanu’s Redemption (Modanhan 2021) is the first literary work written in Chinese on the topic of re-education camps in Xinjiang, China. The semi-autobiographical novel depicts how Banu, a female Uyghur intellectual, seeks self-redemption and new ethnic and gender identities against increasingly stringent social control and rising ethnic tension in the region. This chapter offers a critical reading of the novel and argues that it portrays a literary liberation of women against China’s ethnic repression and patriarchal structures in Uyghur culture. Banu’s morally ‘questionable’ character stands in stark contrast to the prevailing representation of women as ‘pure heroines’ in Uyghur literature and reality. This reflects how Uyghur activists often overlook feminist concerns and regard women as mere tools in achieving their activist goals. The novel questions the myth and practicality of female purity in activism and offers a more complex ethics of survival in which ‘truth-telling’ plays a crucial part

Conservation status:— Thalictrum bouffordii is currently known from Luding, Shimian, and Tianquan counties in the Qionglai mountains region in western Sichuan, China. The two populations in Luding and Tianquan, which we visited in 2020, consist of at least 100 individuals each. However, the size of the population in Shimian remains unknown. The conservation status of T. bouffordii should be considered as “Data Deficient (DD)” before adequate information of this species is acquired (IUCN Standards and Petitions Committee 2019). Notes:— Thalictrum bouffordii is most closely similar to T. xinningense Wang (2017: 408) (Figs. 6‒8) in habit and having clavate filaments, apically recurved styles, and sessile, profoundly ribbed and pubescent achenes, but differs by having proximally glabrous (vs. densely pubescent) stem (Figs. 3D, 7D), inflorescence a many-flowered corymbiform compound monochasium (vs. a thyrse) (Figs. 1, 2, 3B, 4B, 6, 7B, 8), abaxially pubescent (vs. glabrous) sepals (Figs. 3I, 4G, 7I), and purplish (vs. white) filaments (Figs. 3J, 4H, 7J) (also see Wang 2017, 2018a). Geographically T. bouffordii occurs in western Sichuan, whereas T. xinningense is widely distributed in southern Chongqing, northern Fujian, northern Guangdong, northern Guangxi, eastern Guizhou, southwestern Hubei, Hunan, northern Jiangxi, and southern Zhejiang (Zeng et al. 2020a); both species are thus geographically isolated from each other (Fig. 5). As mentioned above, specimens of Thalictrum bouffordii had all been previously misidentified as T. javanicum. Indeed, T. bouffordii is somewhat similar to T. javanicum in habit, but differs by having abaxially pubescent (vs. glabrous) sepals, purplish (vs. white) filaments, and pubescent (vs. glabrous) achenes (also see Backer & Bakhuizen van den Brink 1963). Moreover, as noted by Zeng et al. (2020b), previous records of the occurrence of T. javanicum in China might be a mistake caused by the misapplication of this name to the relevant Chinese populations. The descriptions of T. javanicum in the Chinese floristic works by various authors, including Anonymous (1972, 1976, 2014), Wang & Wang (1979), Wang (1985, 1991, 1993, 2000, 2003, 2004, 2018a), Lin & Zhao (1985), Li (1986), Lin (1992), Liu (2000), Fu & Zhu (2001), Luo & Luo (2008), Wang & Liu (2016), and Xie et al. (2016), have been made mainly based on Chinese specimens, not on material from the type locality, i.e. Java in Indonesia. These Chinese specimens actually belong to T. nepalense Wang (2018b: 641), T. xinningense, and our new species as well, respectively. An identification key to T. bouffordii and its closely similar species including T. javanicum, T. nepalense and T. xinningense is given below.Published as part of Zeng, You-Pai, Yuan, Qiong & Yang, Qin-Er, 2021, Thalictrum bouffordii (Ranunculaceae), a new species from the Qionglai mountains region in western Sichuan, China, pp. 18-28 in Phytotaxa 510 (1) on pages 18-26, DOI: 10.11646/phytotaxa.510.1.2, http://zenodo.org/record/542624

Smart landscapes: revealing air pollution induced stress through in-situ biomonitoring
No full textThe thesis works on the design of a type of smart landscape which builds a data-driven dialog between humans and environment to reveal the environmental stress caused by air pollution. It investigates the methodologies to build an on-site biomonitoring system that emphasizes the design intervention of landscape architecture to make the system widely practicable. This framework aims to supply the idea of the way landscape architects scientifically interpret urban dynamics and support the decision-making process associated with air quality issues.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2022-08-01The student, Lixian Zeng, accepted the attached license on 2020-07-24 at 02:09.The student, Lixian Zeng, submitted this Thesis for approval on 2020-07-24 at 02:29.This Thesis was approved for publication on 2020-07-24 at 13:46.DSpace SAF Submission Ingestion Package generated from Vireo submission #15649 on 2020-10-02 at 15:33:40Made available in DSpace on 2020-10-07T22:44:39Z (GMT).
