INVERSE VARIATIONAL INEQUALITIES AND SECOND-ORDER DYNAMICAL SYSTEMS
We consider the inverse variational inequality problem in finite-dimensional space and study its associated second-order dynamical system. In particular, we propose a second-order dynamical system whose trajectory converges exponentially to the solution

Reconstructing enzyme evolution by protein engineering
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Decreasing solutions of cyclic second-order difference systems
The existence and asymptotic behavior of positive decreasing solutions to the cyclic second-order nonlinear difference system \begin{equation*} \Delta(p_i(n)|\Delta x_i(n)|^{\alpha_i-1}\Delta x_i(n)) =q_i(n)|x_{i+1}(n+1)|^{\beta_i-1}x_{i+1}(n+1) , \quad ...

Collocation methods for a class of second order initial value problems with oscillatory solutions [PDF]
We derive and analyse two families of multistep collocation methods for periodic initial-value problems of the form y" = f(x, y); y((^x)o) = yo, y(^1)(xo) = zo involving ordinary differential equations of second order in which the first derivative ...

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

二阶次线性碰撞系统的次调和解(Subharmonic solutions for sublinear second order systems with impacts)
We prove that there are infinite subharmonic bouncing solutions of sublinear second order systems x″+f(t, x)=0 when f(t, x) satisfies suitable condition in the around of x = 0.
