Renormalization-group improved predictions for Higgs boson production at large pTp_T

We study the next-to-next-to-leading logarithmic order resummation for the large $p_T$ Higgs boson production at the LHC in the framework of soft-collinear effective theory. We find that the resummation effects reduce the scale uncertainty significantly and decrease the QCD NLO results by about $11\%$ in the large $p_T$ region. The finite top quark mass effects and the effects of the NNLO singular terms are also discussed.Comment: 31 pages, 17 figures, version published in Phys.Rev.

以岗位需求为导向的二级医院ICU进修护士教学培训体系的构建及实践

Objective: Establish position requirements-oriented training system of ICU training nurses in secondary hospital .To standardize the teaching management and improve the training effect for the training nurses in our ICU. Methods: Form the ICU training nurse teaching staff; Formulate training manual according to survey results of nurse training demand；Implement clinical teaching in stages according to the content of the training manual; Proceed comprehensive skills assessment in the different stages of training. Results: The pass rate of the 84 training nurses in 2013was 100%, the excellent rate was 25.72%,the good rate was 36.37%. 84 training nurses completed the training task perfectly according to the training manual, and during the training there was no nursing security incidents. Conclusion: To establish position requirements-oriented training system of ICU training nurses is the main method to solve the shortage of nursing professionals  in secondary hospital. This kind of training system is appropriate to the needs of the development of intensive care ,training requirement and clinical requirement. It should be extended in nurse training work in ICU.目的  建立以岗位需求为导向的二级医院ICU进修护士教学培训体系。从而规范本科进修护士的教学管理，提高培训效果。方法  组建ICU进修护士师资队伍；按照进修护士培训需求调查的结果制订进修培训手册；遵照培训手册的内容实施分阶段的临床教学；在进修培训的不同阶段进行ICU综合技能考核。结果  2013年84名进修护士综合技能考核成绩合格率100%，其中优秀率25.72%，良好率36.37%。84名进修护士均遵照培训手册的要求圆满完成培训任务，在培训期间无护理安全事故发生。结论  建立以岗位需求为导向的ICU进修护士教学培训体系是解决当前二级医院ICU护理专业人才紧缺的主要方法。这种培训体系与重症护理发展的需要、护士的培训要求及临床实际工作需要相适应，适于在ICU护士在职培训工作中推广

Cinnamic aldehyde treatment alleviates chronic unexpected stress-induced depressive-like behaviors via targeting cyclooxygenase-2 in mid-aged rats

Ethnopharmacological relevance: COX-2 has been considered as a potent molecular target for prevention and therapy of depression. However, a recent study showed that COX-2 inhibitor does not improve depressive symptoms in persons aged 70 and over. Therefore, whether treatments targeting COX-2 have a clinical efficacy in depression, especially elderly individuals, remains unclear. Cinnamic aldehyde is a major constituent of Cinnamomum cassia, which has exhibited excellent anti-inflammatory activities as a COX-2 inhibitor. To investigate the potential antidepressant effect of cinnamic aldehyde in mid-aged rats

Topological Phases, Local Magnetic Moments, and Spin Polarization Triggered by C558-Line Defects in Graphene

We study the electronic properties of a novel topological defect structure for graphene interspersed with C558-line defects along the Armchair boundary. This system has the topological property of being topologically three-periodic and the type-II Dirac-fermionic character of the embedded topological phase. At the same time, we show computationally that the topological properties of the system are overly dependent on the coupling of this line defect. Using strain engineering to regulate the magnitude of hopping at the defect, the position of the energy level can be easily changed to achieve a topological phase transition. We also discuss the local magnetic moment and the ferromagnetic ground state in the context of line defects, which is the conclusion after considering additional Coulomb interactions. This leads to spin polarization of the whole system. Finally, by modulating the local magnetic moment at the position of the line defect, we achieve a tunable spin quantum conductance in a one-dimensional nanoribbon. Near the Fermi energy level, it also has the property of complete spin polarization. Consequently, spin filtering can be achieved by varying the incident energy of the electrons.Comment: 8 pages, 6 figure
