On two supercongruences involving Almkvist-Zudilin sequences
We prove two supercongruences involving Almkvist-Zudilin sequences, which were originally conjectured by Z.-H. Sun (2020).

On useful schema in survival analysis after heart attack
Recent model of lifetime after a heart attack involves some integer coefficients. Our goal is to get these coefficients in simple way and transparent form. To this aim we construct a schema according to a rule which combines the ideas used in the Pascal triangle and the generalized Fibonacci and Lucas numbers
On variants of Conway and Conolly's meta-Fibonacci recursions.
On vertex stability with regard to complete bipartite subgraphs
A graph G is called (H;k)-vertex stable if G contains a subgraph isomorphic to H ever after removing any of its k vertices. Q(H;k) denotes the minimum size among the sizes of all (H;k)-vertex stable graphs. In this paper we complete the characterization of -vertex stable graphs with minimum size. Namely, we prove that for m ≥ 2 and n ≥ m+2, and as well as are the only -vertex stable graphs with minimum size, confirming the conjecture of Dudek and Zwonek.
