    AbstractThis article begins with the mass conservation of blood platelets on the Gibbs interface, and obtains a relation between interfacial curvature and interfacial concentration of a blood–thrombus. A two-dimensional model is established, and the time-dependent inner solution and outer solution are obtained using the perturbation method, the solution characteristics are discussed

    CeNiAsO: an antiferromagnetic dense Kondo lattice

    A cerium containing pnictide, CeNiAsO, crystallized in the ZrCuSiAs type structure, has been investigated by measuring transport and magnetic properties, as well as specific heat. We found that CeNiAsO is an antiferromagnetic dense Kondo lattice metallic compound with Kondo scale TK∼T_K \sim 15 K and shows an enhanced Sommerfeld coefficient of γ0∼\gamma_0 \sim 203 mJ/mol⋅\cdotK2^{2}. While no superconductivity can been observed down to 30 mK, Ce ions exhibit two successive antiferromagnetic (AFM) transitions. We propose that the magnetic moment of Ce ion could align in the G type AFM order below the first transition at TN1T_{N1}=9.3 K, and it might be modified into the C type AFM order below a lower transition at TN2T_{N2}=7.3 K. Our results indicate that the 3d−4fd-4f interlayer Kondo interactions play an important role in Ni-based Ce-containing pnictide.Comment: 13 pages, 5 figures, to appear in J. Phys.: Condens. Matte
