    Optimal beaconing control for epidemic routing in delay tolerant networks

    No full text
    Owing 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

    Data for: Paleomagnetic results of the Cretaceous chert from Zhongba, southern Tibet: New constraints on the India-Asia collision

    No full text
    The paleomagnetic data are used and discussed in the paper entitled "Paleomagnetic results of the Cretaceous chert from Zhongba, southern Tibet: New constraints on the India-Asia collision" by Shi-Xin Qin, Yong-Xiang Li*, Xiang-Hui Li, Bo Xu, and Hui Luo.The demagnetization results from the Zhongba section are summarized in Table S1 and Table S2. Table S1 contains the data of low temperature component (LTC) and component C1 of the two-component magnetization. Table S2 contains the high temperature component (HTC) data. The late Cretaceous to Paleogene paleopoles of the Tethyan Himalaya (TH) are compiled in Table S3. These data are used to construct the apparent polar wander path (APWP) of the TH

    Zhong-Yong as dynamic balancing between Yin-Yang opposites

    No full text
    Purpose The purpose of this paper is to comment on Peter Ping Li’s understanding of Zhong-Yong balancing, presented in his article titled “Global implications of the indigenous epistemological system from the East: How to apply Yin-Yang balancing to paradox management.” Seeing his understanding of Zhong-Yong balancing being incorrect and incomplete, the author proposes an alternative perspective on Zhong-Yong as dynamic balancing between Yin-Yang opposites. Design/methodology/approach The author first explain why Peter P. Li’s “asymmetry” and “superiority” arguments are flawed by referring to the original text of the classical book of Zhong-Yong (中庸) and a comparison between Zhong-Yong and Aristotle’s doctrine of the mean. The author then propose an alternative approach to Zhong-Yong balancing that is embedded in the original text Zhong-Yong but somehow has been neglected by many Chinese scholars. The author concludes the commentary by unifying the two alternative approaches to Zhong-Yong balancing under the inclusion-selection-promotion-transition (ISPT) framework of Zhong-Yong balancing. Findings There are three main findings. First, as the original text of Zhong-Yong does not prescribe asymmetry, Peter P. Li’s notion of “Yin-Yang balancing” is ironically unbalanced or anti-Zhong-Yong due to his emphasis on asymmetry to the exclusion of symmetry. Second, due to the equivalency between Zhong-Yong and Aristotle’s doctrine of the mean, Peter P. Li’s assertion that “Yin-Yang balancing” is superior as a solution to paradox management is flawed. Third, his “Yin-Yang balancing” solution is only (the less sophisticated) one of two alternative approaches to Zhong-Yong balancing, i.e., ratio-based combination of Yin-Yang opposites. What Peter P. Li and many other Chinese have neglected is another approach to Zhong-Yong that is embedded in the original text of Zhong-Yong, which I call “analysis plus synthesis.” Research limitations/implications As it is a commentary there are no specific limitations except for what can be covered in the space available. Practical implications The “analysis plus synthesis” approach to Zhong-Yong can be adopted by practitioners who are demanded to balance between opposite forces in daily life and work. Social implications The rejection of the “Yin-Yang balancing being superior” assertion facilitates reduction of friction and non-cooperation between intellectual traditions. Originality/value This commentary contributes to the “West meets East” discourse by debunking Peter P. Li’s assertion that Yin-Yang balancing is superior as a solution to paradox management and his prescription that balancing between Yin-Yang opposites must be asymmetric. It also contributes to the Chinese indigenous management research by identifying a largely neglected approach to Zhong-Yong balancing (i.e. “analysis plus synthesis”) that is alternative to the commonly understood ratio-based combination approach (e.g. “Yin-Yang balancing”). In addition, it contributes to the management literature by proposing the ISPT framework of Zhong-Yong balancing. </jats:sec
