Feshbach resonance is a resonance for two-atom scattering with two or more channels,in which a bound state is achieved in one *** show that this resonance phenomenon not only exists during the collisions of massive particles,but also emerges during the coherent transport of massless particles,that is,photons confined in the coupled resonator arrays linked by a separated cavity or a tunable two level system(TLS).When the TLS is coupled to one array to form a bound state in this setup,the vanishing transmission appears to display the photonic Feshbach *** process can be realized through various experimentally feasible solid state systems,such as the couple defected cavities in photonic crystals and the superconducting qubit coupled to the transmission *** numerical simulation based on the finite-different time-domain(FDTD) method confirms our assumption about the physical implementation.

The design criteria for metal-organic frameworks(MOFs)have been established by evaluating the rela-tionship between their key characteristics and magnesium-ion conductivity based on three types of sec-ondary building blocks(Zn_(4)O(CO_(2))_(6):MOF-5 and MOF-177;Cu_(2)(CO_(2))4:MOF-199,MOF-143,MOF-14,and MOF-399;Cu_(2)O_(2)(CO_(2))2:Cu-MOF-74)to achieve pseudo-solid-state magnesium-ion *** found that open-metal sites and channel layouts play a pivotal role in promoting magnesium-ion transport dy-namics at reduced activation energy,transforming MOF scaffolds into ionic-channel analogs.X-ray ab-sorption spectroscopy combined with Raman and Fourier-transform infrared spectroscopy predicted the chemical environment,solvents,and anions that occupied coordinatively unsaturated metal *** chemical compositions of electrolytes determined by^(1)H-NMR(nuclear magnetic resonance)and organic elemental analysis confirmed that isoreticular expansion increases the molar percentage of charge carri-ers,providing high *** current research systematically reveals the impacts of different MOF characteristics on ionic conduction performance,paving the way for the construction of a new class of fast and selective multivalent-ion pseudo-solid electrolytes.

When fed ad libitum （AL）, ectothermic animals usually grow faster and have higher metabolic rate at higher ambient temperature. However, if food supply is limited, there is an energy tradeoff between growth and metabolism. Here we hypothesize that for ectothermic animals under food restriction （FR）, high temperature will lead to a high metabolic rate, but growth will slow down to compensate for the high metabolism. We measure the rates of growth and metabolism of 4 cohorts of5th instar hornworms （Manduca sexta larvae） reared at 2 levels of food supply （AL and FR） and 2 temperatures （20 and 30 ℃）. Our results show that, compared to the cohorts reared at 20 ℃, the ones reared at 30 ℃ have high metabolic rates under both AL and FR conditions, but a high growth rate under AL and a low growth rate under FR, supporting this hypothesis.

目的探讨河南省两城市高中生文化定位、饮酒期望、自我效能和饮酒行为之间的关系，为有针对性地设计预防控制青少年饮酒教育项目提供理论依据。方法采用分层整群随机抽样方法，于2005年11月对河南省郑州、信阳两市6所高中2756名高一、二学生进行匿名问卷调查，利用SPSS13．0和SAS8．10软件完成数据分析。结果调查学生饮酒率为56．5％。文化定位总均分为3．25（3．09，3．42）；饮酒期望总均分为3．02（2．81，3．23）；饮酒自我效能总均分为79．64（60．36，93．21）。传统文化定位、西方文化定位、饮酒积极期望、饮酒消极期望、饮酒自我效能、饮酒行为各因素之间均存在直接或间接关联。过去30d内较少的饮酒天数与较高的饮酒自我效能和饮酒消极期望、较低的饮酒积极期望和西方文化定位直接相关（相关系数分别是0．346、0．282、0．234和0．162），与中国传统文化定位无直接相关。结论调查学生饮酒情况比较严重，不同饮酒信念和文化定位影响饮酒行为的发生，预防控制青少年饮酒教育活动可以此作为切入点进行。

The 12 May 2008 Wenchuan earthquake （Ms=8.0） struck on the Longmen Shan foreland thrust zone. The event took place within the context of long-term uplift of the Longmen Shan range as a result of the extensive eastward-extrusion of crustal materials from the Tibetan plateau against the rheologically strong crust of the Sichuan Basin. The Longmen Shan range is charac- terized by a Pre-Sinian crystalline complex constrained by the Maoxian-Wenchuan-Kangding ductile detach- ment at the western margin and the Yingxiu-Beichuan- Luding ductile thrust at the eastern margin. The Long- men Shan uplift was initiated by intracontinental sub- duction between the Songpan-Ganzi terrane and the Yangtze block during the Pre-Cenozoic. The uplift rate was increased considerably by the collision between the Indian and Eurasian plates since -50 Ma. The Wenchuan earthquake resulted in two major NE-strik- ing coseismic ruptures （i.e., the -275 km long Yingxiu- Beichuan-Qingchuan fault and the -100 km long Anx- ian-Guanxian fault）. Field investigations combined with focal solutions and seismic reflection profiles suggest that the coseismic ruptures are steeply dipping close-to- pure reverse or right reverse oblique slip faults in the -15 km thick upper crust. These faults are unfavorably oriented for frictional slip in the horizontally compres- sional regime, so that they need a long recurrence interval to accumulate the tectonic stress and fluid pres- sure to critically high levels for the formation of strong earthquakes at a given locality. It is also found that all the large earthquakes （Ms〉7.0） occurred in the fault zones across which the horizontal movement velocities measured by the GPS are markedly low （〈3 mm/yr）. The faults, which constitute the northeastern fronts of the enlarging Tibetan plateau against the strong Sichuan Basin, Ala Shan and Ordos blocks, are very destructive, although their average recurrence intervals are generally long.
