DOI: 10.1063/5.0103436
Abstract: We study dynamics of a generic quadratic diffeomorphism, a 3D generalization of the planar Hénon map. Focusing on the dissipative, orientation preserving case, we give a comprehensive parameter study of codimension-one and two bifurcations. Periodic… read more here.

Abstract: We study the local behavior of a solution to a generalized non-stationary Stokes system with singular coefficients in Rn with n≥ 2. One of our main results is a bound on the vanishing order of a… read more here.

DOI: 10.1111/1365-2478.12647
Abstract: Compensation for geometrical spreading along the ray-path is important in amplitude variation with offset analysis especially for not strongly attenuative media since it contributes to the seismic amplitude preservation. The P-wave geometrical spreading factor is… read more here.

DOI: 10.1186/s13662-018-1675-y
Abstract: We consider an SIRS epidemic model with a more generalized non-monotone incidence: χ(I)=κIp1+Iq$\chi(I)=\frac{\kappa I^{p}}{1+I^{q}}$ with 01$, by qualitative and bifurcation analyses, we show that the model undergoes a saddle-node bifurcation, a Hopf bifurcation and a… read more here.
