Rare decays Bs→l+l−B_s\to l^+l^- and B→Kl+l−B\to Kl^+l^- in \the topcolor-assisted technicolor model

We examine the rare decays $B_s\to l^+l^-$ and $B\to Kl^+l^-$ in the framework of the topcolor-assisted technicolor ($TC2$) model. The contributions of the new particles predicted by this model to these rare decay processes are evaluated. We find that the values of their branching ratios are larger than the standard model predictions by one order of magnitude in wide range of the parameter space. The longitudinal polarization asymmetry of leptons in $B_s \to l^+l^-$ can approach \ord(10^{-2}). The forward-backward asymmetry of leptons in $B \to Kl^+l^-$ is not large enough to be measured in future experiments. We also give some discussions about the branching ratios and the asymmetry observables related to these rare decay processes in the littlest Higgs model with T-parity.Comment: 29 pages, 9 figure, corrected typos, the version to appear in PR

The Effects of Minimal Length, Maximal Momentum and Minimal Momentum in Entropic Force

In this paper, the modified entropic force law is studied by using a new kind of generalized uncertainty principle which contains a minimal length, a minimal momentum and a maximal momentum. Firstly, the quantum corrections to the thermodynamics of a black hole is investigated. Then, according to Verlinde's theory, the generalized uncertainty principle (GUP) corrected entropic force is obtained. The result shows that the GUP corrected entropic force is related not only to the properties of the black holes, but also to the Planck length and the dimensionless constants $\alpha _{\rm{0}}$ and $\beta _{\rm{0}}$. Moreover, based on the GUP corrected entropic force, we also derive the modified Einstein's field equation (EFE) and the modified Friedmann equation.Comment: 16 pages. arXiv admin note: substantial text overlap with arXiv:1604.0470

Inverse Projection Representation and Category Contribution Rate for Robust Tumor Recognition

Sparse representation based classification (SRC) methods have achieved remarkable results. SRC, however, still suffer from requiring enough training samples, insufficient use of test samples and instability of representation. In this paper, a stable inverse projection representation based classification (IPRC) is presented to tackle these problems by effectively using test samples. An IPR is firstly proposed and its feasibility and stability are analyzed. A classification criterion named category contribution rate is constructed to match the IPR and complete classification. Moreover, a statistical measure is introduced to quantify the stability of representation-based classification methods. Based on the IPRC technique, a robust tumor recognition framework is presented by interpreting microarray gene expression data, where a two-stage hybrid gene selection method is introduced to select informative genes. Finally, the functional analysis of candidate's pathogenicity-related genes is given. Extensive experiments on six public tumor microarray gene expression datasets demonstrate the proposed technique is competitive with state-of-the-art methods.Comment: 14 pages, 19 figures, 10 table

The application of nursing training in junior residents rotated in ophthalmology operating room

目的  提高初次轮转眼科手术室的住院医师对手术医疗原则认识。方法  对自2014年12月至2015年12月来初次轮转眼科手术室住院医师共28人进行无菌原则、手术分级原则、两方核查原则进行培训，培训后问卷调查。结果  在为期2个月的培训后，住院医师对无菌原则、手术分级原则和核查原则的认识掌握均有较大提高，能够遵守培训内容顺利完成手术。结论  眼科手术室护理人员进行低年资住院医师的培训对于他们掌握认识无菌原则、手术分级原则和核查原则有较大帮助，掌握程度在培训后大大提高，护理培训对年轻医生轮转手术室是必不可少的一部分。Objective: To improve medical understanding of principles of surgical treatment among residents rotated in ophthalmology operating room. Methods: From December 2014 to December 2015, a total of 28 junior residents received training with respect to principles of sterility, classification and two party’s verification, and answered questionnaire after training. Results: After two months of training, the resident obtained better understanding of the principles, and completed surgery successfully in line with the training content. Conclusion: The operating room nurse plays an important role in helping the junior residents understand aseptic principles, operation classification principle and verification principle. The junior residents improved greatly after the training. Nursing training is an essential part for junior residents rotated in ophthalmology operating room
