Convolutions of the generalized Pell and Pell-Lucas numbers
Filomat, 2016 We consider the convolution of the generalized Pell numbers-P(s) n,m and the convolution of the generalized Pell-Lucas numbers-Q(s) n,m. For s = 0, the sequence P(0) n,m represents the generalized Pell numbers Pn;m, and the sequence Q(0) n,m represents the generalized Pell-Lucas numbers Qn,m ([1], [2]). For m = 2 and s = 0, the numbers P(0)

Literacy, Volume 60, Issue 2, May 2026.ABSTRACT For some students, handwriting difficulties persist from primary to secondary school. The aim of this study was to understand parents' perceptions of their child's experience with handwriting and typing. Fifteen parents of children attending secondary schools in England participated in semistructured interviews.

Advancing Systemic Risk Assessment for Complex, Interdependent Systems: A Research Agenda
Risk Analysis, Volume 46, Issue 5, May 2026.ABSTRACT Engineering risk assessment has traditionally focused on direct impacts to individual assets or systems. However, as society's most notable risks increasingly stem from complex, interdependent systems, conventional methods fail to capture the cascading consequences and deepening uncertainty. Addressing this gap requires developing or extending

BTLE: Atomic swaps with time-lock puzzles
Journal of Mathematical CryptologyWe present BTLE (Broadcast Time-Lock Exchange Protocol), a two-step protocol that aims to decentralize exchange of funds between two blockchains in scenarios similar to online exchanges. BTLE leverages time-lock puzzles to achieve that.

On Mixed $b$-concatenations of Pell and Pell-Lucas Numbers which are Pell Numbers
Mathematica PannonicaLet $(P_n)_{n\ge 0}$ and $(Q_n )_{n\ge 0}$ be the Pell and Pell-Lucas sequences. Let $b$ be a positive integer such that $b\ge 2.$ In this paper, we prove that the following two Diophantine equations $P_{n}=b^{d}P_{m}+Q_{k}$ and $P_{n}=b^{d}Q_{m}+P_{k}$ with $d,$ the number of digits of $P_k$ or $Q_k$ in base $b,$ have only finitely many solutions in ...
