A novel measurement of Bs0B^0_s and Ds−D^-_s lifetimes using semileptonic decays at LHCb

I report new, world-leading LHCb results on heavy meson lifetimes. We use a novel approach that suppresses the shortcomings typically associated with reconstruction of semileptonic decays, allowing for precise measurements of lifetimes and other properties in collider experiments. We achieve a 15% and a $2\times$ improvement over current best determinations of the flavor-specific $B^0_s$ lifetime and $D^-_s$ lifetime, respectively.Comment: 12 pages, 6 figures.

Optimal use of polyethylene glycol for preparation of small bowel video capsule endoscopy: a network meta-analysis

<p><b>Objective:</b> Standardized strategy of bowel preparation before video capsule endoscopy (VCE) remains controversial. This study aimed to assess the ideal dose of PEG, based on small bowel visualization quality (SBVQ), diagnostic yield (DY), and complete rate (CR) of VCE using a network meta-analysis (NMA) of randomized controlled trials (RCTs).</p> <p><b>Methods:</b> This NMA included RCTs comparing any of the following bowel preparation interventions for VCE: fasting overnight (“Fast”), 1 liter PEG (“PEG 1L”), 2-liter PEG (“PEG 2L”), or 4-liter PEG (“PEG 4L”). The authors searched papers in PubMed, Cochrane Library, and Embase as of June 2016. The cumulative ranking (SUCRA) probabilities to rank different doses of PEG and Fast were used.</p> <p><b>Results:</b> The search engine provided 102 studies. Nine RCTs including 982 patients were incorporated into this analysis. All studies showed low risk of bias of blinding. SUCRA provided an initial ranking among these strategies, in which PEG 2 L showed the best score in SBVQ (PEG 2 L, 89.4%; PEG 1 L, 62.5%; PEG 4 L, 44.0%; Fast, 4.1%) and DY (PEG 2 L, 74.6%; PEG 1 L 28.1%; PEG 4 L 65.9%; Fast 31.4%) of VCE. No significant difference was shown in the analysis of CR.</p> <p><b>Conclusions:</b> This study recommends PEG 2 L as the ideal dose, which may improve the SBVQ of VCE and, therefore, diagnostic accuracy. Multi-center randomized controlled trials are required to verify these findings.</p

Measurement and simulation of the relatively competitive advantages and weaknesses between economies based on bipartite graph theory

<div><p>The input-output table is very comprehensive and detailed in describing the national economic systems with abundant economic relationships, which contain supply and demand information among various industrial sectors. The complex network, a theory, and method for measuring the structure of a complex system can depict the structural characteristics of the internal structure of the researched object by measuring the structural indicators of the social and economic systems, revealing the complex relationships between the inner hierarchies and the external economic functions. In this paper, functions of industrial sectors on the global value chain are to be distinguished with bipartite graph theory, and inter-sector competitive relationships are to be extracted through resource allocation process. Furthermore, quantitative analysis indices will be proposed under the perspective of a complex network, which will be used to bring about simulations on the variation tendencies of economies’ status in different situations of commercial intercourses. Finally, a new econophysics analytical framework of international trade is to be established.</p></div
