By reformulating four hypergeometric series formulae, we derive 36 Apéry-like series expressions for the Riemann zeta function, including a couple of identities conjectured by Sun [New series for some special values of L-functions. Nanjing Univ J Math. 2015;32(2): 189–218]. 相似文献

A numerical analysis of flow and concentration fields of macromolecules in a, slightly curved blood vessel was carried out.
Based on these results, the effect of the bifurcation of a flow on the mass transport in a curved blood vessel was discussed.
The macromolecules turned out to be easier to deposit in the inner part of the curved blood vessel near the critical Dean
number. Once the Dean number is higher than the critical number, the bifurcation of the flow appears. This bifurcation can
prevent macromolecules from concentrating in the inner part of the curved blood vessel. This result is helpful for understanding
the possible correlations between the blood dynamics and atherosclerosis.

Plane surface suddenly set in motion in a viscoelastic fluid with fractional Maxwell model 总被引:6,自引:0,他引:6
The fractional calculus approach in the constitutive relationship model of viscoelastic fluid is introduced. The flow near
a wall suddenly set in motion is studied for a non-Newtonian viscoelastic fluid with the fractional Maxwell model. Exact solutions
of velocity and stress are obtained by using the discrete inverse Laplace transform of the sequential fractional derivatives.
It is found that the effect of the fractional orders in the constitutive relationship on the flow field is significant. The
results show that for small times there are appreciable viscoelastic effects on the shear stress at the plate, for large times
the viscoelastic effects become weak.

Synthesis of titanium nitride thin films deposited by a new shielded arc ion plating 总被引:2,自引:0,他引:2

Thin films of titanium nitride (TiN) were deposited on stainless steel substrates by a modified deposition technique, double-layered shielded arc ion plating with vicarious circular holes (DL-SAIP). The results show that the TiN film with the distance of 10 mm between the double-layered shield plates had the least droplets. The deposition rate of the films prepared with the new technique was more homogeneous than that of all the other shielded arc ion plating. The film/substrate adhesion and microhardness values of the TiN films were higher than 40 N and 18 GPa, respectively. Thus such TiN thin films can be expected in applications. 相似文献
