In order to solve the problem of how to collect and manage large amount of location information and improve the accuracy of location service, interactive information supporting system based on ontology and location service is presented in this paper. It can transmit special information about users＇ location to front-end instantaneously, so it is very convenient for their daily life. It makes full use of the available wireless communication, which is easy to arrange and convenient for users.

Precise and early detection ofβ-amyloid(Aβ)deposits in situ and in real time is pivotal to the diagnosis and early intervention of Alzheimer’s disease(AD).Optical imaging stands out to be a promising technique for such a task;however,it still remains a big challenge,due to the lack of high-performance imaging contrast *** by poor blood-brain barrier(BBB)penetrability,short-wavelength excitation and emission,as well as the aggregation-caused quenching effect,the widely used goldstandard probes cannot be used for early in-vivo imaging of Aβ***,we integrate the Aβdeposits-favored geometry,amphiphilic and zwitterionic molecular structure,extended D-π-A electronic structure,and 3 D conformation into one molecule,facilely establishing a simple and economic imaging contrast agent that enjoys high specificity and affinity to Aβdeposits,good BBB penetrability,bright red/near-infrared fluorescence,low interference from autofluorescence,aggregation-induced emission(AIE)feature,high signal-to-noise ratio(SNR),and high ***-vitro,ex-vivo,and in-vivo experiments with different strains of mice indicate that AIE-CNPy-AD holds the universality to Aβdeposits ***,AIE-CNPy-AD is even able to precisely trace the small and sparsely-distributed Aβdeposits in AD model mice as young as 4-month-old APP/PS1 mice,the youngest having Aβ***,the present probe could clearly reveal the increase and enlargement of Aβdeposits as the mice ***,AIE-CNPy-AD might be an ideal alternative for early AD diagnosis and highly reliable monitoring of AD progression.

文章使用2020年中国家庭动态跟踪调查数据,考察了亲子关系对老年人数字鸿沟的影响和作用机制。研究发现,亲子关系的提高有利于改善老年人数字鸿沟问题。异质性分析发现,亲子关系对老年人数字鸿沟的影响在具有不同户口、受教育程度的老年人群体中存在差异。机制的探讨发现,存在代际支持的中介作用。建议充分发挥家庭补偿功能,搭建亲子沟通的桥梁,开展差异化培训,加强代际支持,鼓励数字反哺,从而强化亲子关系对老年人数字鸿沟的促进作用。

The entanglement of the generalized two-mode binomial states in the phase damping channel is studied by making use of the relative entropy of the entanglement. It is shown that the factors of q and p play the crucial roles in control the relative entropy of the entanglement. Furthermore, we propose a scheme of teleporting an unknown state via the generalized two-mode binomial states, and calculate the mean fidelity of the scheme.
