目的探讨中国人类免疫缺陷病毒(HIV)/艾滋病(AIdS)患者HIV特异性细胞毒性T淋巴细胞(CTL)应答的特征。方法以HIV-1B、C亚型构建的2个全基因组肽库作为抗原,通过酶联免疫斑点(ELISPOT)法检测HIV/AIdS患者HIV特异性CTL应答。结果无论HIV-1B亚型还是HIV-1C亚型所构建肽库的应答效应和频率主要集中在Gag和Nef蛋白,其他蛋白也有不同程度的应答。HIV-1B、C亚型间应答比较,整体范围大致相同,但单个肽段水平还存在着一定差异,B亚型应答频率最高的是Nef的GPKEPFrdYVdrFYKTLr(5/17,29．4%)和Gag的LWVYHTQ- GYFPdWQNY(5/17,29．4%),C亚型应答频率最高的是Gag的GPKEPFrdYVdrFFKTLr应答频率为35．29%。结论中国人群CTL应答多集中在Gag和Nef蛋白,B、C亚型在单个肽段水平略有差异,提示中国人群的CTL应答研究对设计针对中国人群的HIV疫苗有较重要的意义。

Google Page rank is a prevalent algorithm for ranking the significance of nodes or websites in a network,and a recent quantum counterpart for Page rank algorithm has been raised to suggest a higher accuracy of ranking comparing to Google Page *** quantum Page rank algorithm is essentially based on quantum stochastic walks and can be expressed using Lindblad master equation,which,however,needs to solve the Kronecker products of an O(N^(4))dimension and.r.quires severely large memory and time when the number of nodes N in a network increases above ***,we present an efficient solver for quantum Page rank by using the runge-Kutta method to reduce the matrix dimension to O(N^(2))and employing Tensor Flow to conduct GPU parallel *** demonstrate its performance in solving quantum stochastic walks on Erdos-rényi graphs using an rTX 2060 *** test on the graph of 6000 nodes requires a memory of 5.5 GB and time of 223 s,and that on the graph of 1000 nodes requires 226 MB and 3.6 *** with QSWalk,a currently prevalent Mathematica solver,our solver for the same graph of 1000 nodes reduces the required memory and time to only 0.2%and 0.05%.We apply the solver to quantum Page rank for the USA major airline network with up to 922 nodes,and to quantum stochastic walk on a glued tree of 2186 *** efficient solver for large-scale quantum Page rank and quantum stochastic walks would greatly facilitate studies of quantum information in real-life applications.

Through a very detailed investigation involving a set of simple perturbative amplitudes we show that the answer for the question put in the title of the present work is: undoubtedly NO! We are not restricting the sentence to the amplitudes which are consid.r.d as anomalous. The referred investigation is performed by using a proced.r. alternative to the traditional regularization methods. In the context of such a strategy the amplitudes are not modified in intermediary steps of the calculation, like traditional regularization proced.r.s do, and only the validity of the linearity in the integration operation is assumed in the operations made in Feynman integrals typical of the perturbative calculations. The central point of the investigation is the question related to the consistent interpretation of the amplitudes. For these purposes, in all amplitudes having power counting indicating the possibility of divergences, the relations among Green functions, Ward identities and low energy limits are analyzed, in a model having different species of massive 1/2 spin fermions coupled to spin 0 and 1 (even and odd parity) boson fields, formulated in a space-time dimension d=1+1. We show that the maintenance of the linearity in operations involving Feynman integrals excludes the possibility of an anomalous term in the Ward identity relating the axial-vector and the pseudo-scalar-vector two point functions amplitudes. In addition, we show that it is not possible the maintenance of Ward identities and low energy limits in a consistent way if the amplitudes of the perturbative calculations are quantities to be regularized, just because there is no regularization method which is capable to give acceptable results for the divergent objects present in the calculations. This conclusion includes the dimensional regularization method which cannot give unique results if the linearity and the symmetric integration are simultaneously required in Feynman integrals.

Semiconductor devices are strong competitors in the race for the development of quantum computational *** this work,we interface two semiconductor building blocks of different dimensionalities with complementary properties:(1)a quantum dot hosting a single exciton and acting as a nearly ideal single-photon emitter and(2)a quantum well in a 2d microcavity sustaining polaritons,which are known for their strong interactions and unique hydrodynamic properties,including ultrafast real-time monitoring of their propagation and phase *** the present experiment,we can thus observe how the injected single particles propagate and evolve inside the microcavity,giving rise to hydrodynamic features typical of macroscopic systems despite their genuine intrinsic quantum *** the presence of a structural defect,we observe the celebrated quantum interference of a single particle that produces fringes reminiscent of wave *** this behavior could be theoretically expected,our imaging of such an interference pattern,together with a measurement of antibunching,constitutes the first demonstration of spatial mapping of the self-interference of a single quantum particle impinging on an obstacle.
