Contagion processes on the static and activity driven coupling networks

The evolution of network structure and the spreading of epidemic are common coexistent dynamical processes. In most cases, network structure is treated either static or time-varying, supposing the whole network is observed in a same time window. In this paper, we consider the epidemic spreading on a network consisting of both static and time-varying structures. At meanwhile, the time-varying part and the epidemic spreading are supposed to be of the same time scale. We introduce a static and activity driven coupling (SADC) network model to characterize the coupling between static (strong) structure and dynamic (weak) structure. Epidemic thresholds of SIS and SIR model are studied on SADC both analytically and numerically with various coupling strategies, where the strong structure is of homogeneous or heterogeneous degree distribution. Theoretical thresholds obtained from SADC model can both recover and generalize the classical results in static and time-varying networks. It is demonstrated that weak structures can make the epidemics break out much more easily in homogeneous coupling but harder in heterogeneous coupling when keeping same average degree in SADC networks. Furthermore, we show there exists a threshold ratio of the weak structure to have substantive effects on the breakout of the epidemics. This promotes our understanding of why epidemics can still break out in some social networks even we restrict the flow of the population

护理安全品管圈在血管外科护理中的应用效果

Objective: To study the effects of nursing safety quality control circle in the nursing in department of vascular surgery. Methods: Totally 230 patients in vascular surgery department from January 2015 to January 2016 were randomly divided into 2 groups. Assessment the risk factors of disease for each patient , 115 cases in the control group, the shift nurses nurse by traditional method; 115 cases in experimental group ,who were given quality control circle to improve the nursing quality., and the adverse event and compliance,satisfaction to nurses of the patients were compared. Results: The incidence of adverse events and complications (6%) in the experimental group were lower than those in the control group (15.5%). The patients' satisfaction with nurses' job (97.4%) was higher than that of the control group (87%). Conclusion: The implementation of nursing safety quality control circle activities in vascular surgery nursing, effectively reduce the incidence of adverse events and complications during hospitalization, improve the quality of nursing and help patients recover soon.目的  探讨护理安全品管圈在血管外科护理中的应用效果。方法  随机选取2015年1月—2016年1月在本科住院患者230例并随机将其分为两组，对每位患者进行疾病危险因素评估，对照组115例，各交接班护士采用传统护理方法；实验组115例，对患者实施护理安全品管圈活动提高护理质量，比较两组的不良事件和并发症的发生率、患者对护士工作的满意度、患者住院天数。结果  实验组不良事件和并发症的发生率（6%）均低于对照组（15.5%）；患者对护士工作的满意度（97.4%）高于对照组（87%），住院天数较对照组也大大缩短。结论  在血管外科护理中实施护理安全品管圈活动，有效的降低了患者住院期间不良事件和并发症的发生率，提高了护理质量，有助于患者早日康复

Coherent phonon Rabi oscillations with a high frequency carbon nanotube phonon cavity

Phonon-cavity electromechanics allows the manipulation of mechanical oscillations similar to photon-cavity systems. Many advances on this subject have been achieved in various materials. In addition, the coherent phonon transfer (phonon Rabi oscillations) between the phonon cavity mode and another oscillation mode has attracted many interest in nano-science. Here we demonstrate coherent phonon transfer in a carbon nanotube phonon-cavity system with two mechanical modes exhibiting strong dynamical coupling. The gate-tunable phonon oscillation modes are manipulated and detected by extending the red-detuned pump idea of photonic cavity electromechanics. The first- and second-order coherent phonon transfers are observed with Rabi frequencies 591 kHz and 125 kHz, respectively. The frequency quality factor product fQ_m~2=10^12 Hz achieved here is larger thank k_B T_base/h, which may enable the future realization of Rabi oscillations in the quantum regime

Strongly-coupled nanotube electromechanical resonators

Coupling an electromechanical resonator with carbon-nanotube quantum dots is a significant method to control both the electronic charge and the spin quantum states. By exploiting a novel micro-transfer technique, we fabricate two strongly-coupled and electrically-tunable mechanical resonators on a single carbon nanotube for the first time. The frequency of the two resonators can be individually tuned by the bottom gates, and strong coupling is observed between the electron charge and phonon modes of each resonator. Furthermore, the conductance of either resonator can be nonlocally modulated by the phonon modes in the other resonator. Strong coupling is observed between the phonon modes of the two resonators, which provides an effective long distance electron-electron interaction. The generation of phonon-mediated-spin entanglement is also theoretically analyzed for the two resonators. This strongly-coupled nanotube electromechanical resonator array provides an experimental platform for future studies of the coherent electron-phonon interaction, the phonon mediated long-distance electron interaction, and entanglement state generation

The era of multigene panels comes? The clinical utility of Oncotype DX and MammaPrint

The AJCC Cancer Staging Manual, eighth edition published in late 2016, will become the new global guideline for cancer diagnosis and treatment from January 1, 2018. The new edition for the tumor staging system has numerous updates, including building up the prognostic stage group of tumors for the first time and adding a large number of non-anatomical factors into the prognostic evaluation. Oncotype DX and MammaPrint are two of the genomic predictors that will be part of routine clinical practice in the future. Numerous studies have proved the clinical utility of multigene panels in predicting clinical outcome and treatment response. Here we present our review of the studies on these multigene panels and their application to breast cancer
