To verify the size and emergence time of new permeability pathways (NPPs) in malaria parasites, the permeability of the Plasmodium falciparum-infected erythrocytes was tested with different particle sizes of nanomaterials by flow cytometry assay. The results confirmed the permeability of the host cell membrane increases with parasite maturation for the stage-development evolution of NPPs, and especially found that a particle size of about 50 nm had higher efficiency. As a kind of the novel nanomaterials, nitrogen-doped carbon dots (NCDs) showed no toxicity, specificity binding ability to the malaria parasites, and could label live elder blood-stage P. falciparum through NPPs, indicating the potential application in cell imaging. NPPs and some nanomaterials such as NCDs deserve more attention and exploration for the elimination and prevention of malaria. 相似文献

We derive a new differential formula about a kind of product of polynomials and then apply it to analyze some properties of multi-electron state “related to Laughlin wave function“. The entangled state representation for describing electrons in uniform magnetic field is used. 相似文献

We calculate the new physics contributions to the neutral B0d and B0s meson mass splitting △Md and △Ms induced by the box diagrams involving the charged-Higgs bosons in the top quark two-Higgs doublet model (T2HDM).Using the precision data, we obtain the bounds on the parameter space of the T2HDM: (a) For fixed MH = 400 Ge V and δ = [0°,60°], the upper bound on tanβ is tanβ≤ 30 after the inclusion of major theoretical uncertainties; (b) For the case of tanβ≤ 20, a light charged Higgs boson with a mass around 300 Ge V is allowed; and (c) The bounds on tanβ and MH are strongly correlated: a smaller (larger) tanβ means a lighter (heavier) charged Higgs boson. 相似文献

Using the modified CK's direct method, we build the relationship between new solutions and old ones and find some new exact solutions to the (3+1)-dimensional potential-YTSF equation. Based on the invariant group theory, Lie point symmetry groups and Lie symmetries of the
(3+1)-dimensional potential-YTSF equation are obtained. We also get
conservation laws of the equation with the given Lie symmetry. 相似文献

A future Higgs factory is being designed for precise measurement of Higgs characteristics and to search for new physics. In this paper we propose that the Higgs-photon associated production process, e+e-→γh could be a useful channel for new physics. We express new physics model-independently in the effective Lagrangian approach,and find that the new physics effects of γh have only two degrees of freedom, much fewer than the Higgsstrahlung process. This point could be used to reduce the degeneracies of Wilson coefficients. We also calculate for the first time the 95% confidence level(CL) bounds of γh at the Higgs factory, and prove that γh is more sensitive to some dimension-6 operators than the current experimental data. In the optimistic scenario new physics effects may be observed at the CEPC or FCC-ee after the first couple of years of their run. 相似文献

A new bipartite entangled state describing the parametric down-conversion process and its applications in quantum optics 下载免费PDF全文
We construct a new bipartite entangled state(NBES),which describes both the squeezing and the entanglement involved in the parametric down-conversion process and can be produced using a symmetric beam splitter.Constructing asymmetric ket-bra integrations based on the NBES leads to some new squeezing operators,which clearly exhibit the relationships between squeezing and entangled state transformations.Moreover,an entangled Wigner operator with a definite physical meaning is also presented. 相似文献

BaBar合作组在 e+e-→f0(980) 衰变道的 f0(980) 不变质量谱上发现了一个新强子态Y(2175)。 随后, BES和Belle实验都相继证实了这一发现。 与此同时, 理论家们也对Y(2175)的内部性质进行了大量的研究。 本工作对目前Y(2175)在实验和理论上的进展进行了详细的评述。同时,讨论了在f0(980) 不变质量谱中的2175 MeV以上能区寻找其它增长结构的可能性。Since the BaBar Collaboration announced a new hadron Y(2175) observed in the f0(980) invariant mass spectrum of e+e-→ f0(980), both BES and Belle confirmed BaBar’s observation. Meanwhile, the theorist also carries out the study to reveal the underlying properties of Y(2175). In this review paper, we give a detailed review of the present experimental and theoretical statues of Y(2175). In terms of the published experimental data of Y(2175), we also discuss the possibility of searching for other enhancement structuresafter 2175 MeV in the f0(980) invariant mass spectrum. 相似文献

The SO(3) gauge extension of SM, which is proposed to present a successfulexplanation for the observed small masses of neutrino and the nearly tri-bimaximal neutrino mixing, predicted the vector-like SO(3) triplet Majorana neutrinos and SUL(2) double Higgs bosons. In this work we calculate branching ratios of the charged lepton flavor violating decays lIlJV (V=γ,Z) induced by these Majorana neutrinos and Higgs bosons. We find that under the model parameters constrained by experimental bounds on the decays Z→lIlJ, the branching ratio of decays lI→lJγ can be up to 10-10, which may be accessible at the future experiments. 相似文献
