Shi arrangements and low elements in affine Coxeter groups
No full textGiven an affine Coxeter group , the corresponding Shi arrangement is a refinement of the corresponding Coxeter hyperplane arrangements that was introduced by Shi to study Kazhdan-Lusztig cells for . In particular, Shi showed that each region of the Shi arrangement contains exactly one element of minimal length in . Low elements in were introduced to study the word problem of the corresponding Artin-Tits (braid) group and turns out to produce automata to study the combinatorics of reduced words in .
In this article, we show in the case of an affine Coxeter group that the set of minimal length elements of the regions in the Shi arrangement is precisely the set of low elements, settling a conjecture of Dyer and the second author in this case. As a byproduct of our proof, we show that the descent-walls -- the walls that separate a region from the fundamental alcove -- of any region in the Shi arrangement are precisely the descent walls of the alcove of its corresponding low element.v.2 30 pages, 6 figures; to appear in Journal of the CM
Shi arrangements and low elements in Coxeter groups
No full textGiven an arbitrary Coxeter system and a nonnegative integer , the -Shi arrangement of is a subarrangement of the Coxeter hyperplane arrangement of . The classical Shi arrangement () was introduced in the case of affine Weyl groups by Shi to study Kazhdan-Lusztig cells for . As two key results, Shi showed that each region of the Shi arrangement contains exactly one element of minimal length in and that the union of their inverses form a convex subset of the Coxeter complex. The set of -low elements in were introduced to study the word problem of the corresponding Artin-Tits (braid) group and they turn out to produce automata to study the combinatorics of reduced words in .
In this article, we generalize and extend Shi\u27s results to any Coxeter system for any : (1) the set of minimal length elements of the regions in a -Shi arrangement is precisely the set of -low elements, settling a conjecture of the first and third authors in this case; (2) the union of the inverses of the (-)low elements form a convex subset in the Coxeter complex, settling a conjecture by the third author, Nadeau and Williams.44 pages, 7 figures; to appear in Proceedings of the London Mathematical Societ

Complete genome sequence of a sub-subgenotype 2.1i isolate of classical swine fever virus from China
No full textCitation: Zhang, B., Mi, S., Bao, F., Guo, H., Tu, C., Shi, J., & Gong, W. (2017). Complete genome sequence of a sub-subgenotype 2.1i isolate of classical swine fever virus from China. Genome Announcements, 5(14). doi:10.1128/genomeA.00127-17The complete genome sequence of a sub-subgenotype 2.1i isolate of classical swine fever virus (CSFV), GD317/2011, was determined. Notably, GD317/2011 is distant from the sub-subgenotype 2.1b isolate HEBZ at genes of Erns, E1, E2, P7, NS2, NS5A and the 3=-nontranslated region (3=-NTR) but is closely related to that at genes of Npro, Core, NS3, NS4A, NS4B, and NS5B. © 2017 Zhang et al
The United States and Iraq\u27s Shi\u27ite Clergy: Partners or Adversaries?
No full textThe author addressed the critical need to gain the cooperation or at least the passive tolerance of the Shi\u27ite clerics and community. Such an effort could become more challenging as time goes on, and one of the recurring themes of this monograph is the declining patience of the Shi\u27ite clergy with the U.S. presence. By describing the attitudes, actions, and beliefs of major Shi\u27ite clerics, the author underscores a set of worldviews that are profoundly different from those of the U.S. authorities currently in Iraq and Washington. Some key Shi\u27ite clerics are deeply suspicious of the United States, exemplified by conspiracy theories. These suggest that Saddam\u27s ouster was merely a convenient excuse, allowing the United States to implement its own agenda. Other clerical leaders are more open-minded but not particularly grateful for the U.S. presence, despite their utter hatred for Saddam and his regime.https://press.armywarcollege.edu/monographs/1776/thumbnail.jp
Harmonizing Biodiesel Fuel Standards in East Asia: Current Status, Challenges and Way Forward
No full textAbstract: This paper discusses the development of and policy towards biodiesel fuel (BDF) in the East Asia Summit (EAS) Region (hereafter East Asia), with a focus on activities related to harmonizing BDF standards. It finds that the EAS countries have actively promoted the development of BDF for a variety of reasons. To minimize problems with engines arising from the use of BDF, most EAS countries have established their national BDF standards. However, these diverse standards cause barriers for BDF trade and act against the regional interest in maximizing benefits from BDF production and utilization. Therefore, the EAS policy makers decided to harmonize BDF standards, and a regional benchmark standard has been published. Through a comparative review of existing national standards against the benchmark, it finds that the harmonization is beneficial economically and environmentally, and is technically feasible but practically stalled due to the lack of political determination. Therefore, among a few policy implications, the key message to deliver is a call for political determination to implement the harmonization in the EAS region. Since harmonization of BDF standards has been tried in other regions, the findings of this paper may supplement the literature, enhance understanding of the EAS case, and provide lessons and implications that may be helpful in advancing similar harmonization elsewhere.
