The Generalized Order-k Lucas Sequences in Finite Groups

Journal of Applied Mathematics, 2012
We study the generalized order-k Lucas sequences modulo m. Also, we define the ith generalized order-k Lucas orbit lAi,{α1,α2,…,αk-1}(G) with respect to the generating set A and the constants α1,α2, and αk-1 for a finite group G=〈A〉.

Almost repdigits in balancing and Lucas-balancing sequences [PDF]

Notes on Number Theory and Discrete Mathematics
In this paper, we define the notion of almost repdigit as a positive integer whose digits are all equal except for at most one digit, and we search all terms of the balancing and Lucas-balancing sequences which are almost repdigits.

Effect of Time to Start of Biologic Therapy on Treatment Response in Childhood Arthritis: Results From the UCAN CAN‐DU Cohort

Arthritis &Rheumatology, EarlyView.
Objective To estimate the effect of time from symptom onset to start of biologic treatment on achieving inactive arthritis within six months in a cohort of patients with juvenile idiopathic arthritis (JIA). Methods The international UCAN CAN‐DU study prospectively enrolled patients with JIA across Canada and the Netherlands.

Impact of evolving treatment patterns on interstitial lung disease progression in systemic sclerosis using the EUSTAR database

Arthritis &Rheumatology, Accepted Article.
Background The treatment landscape for systemic sclerosis‐associated interstitial lung disease (SSc‐ILD) has evolved with increasing immunosuppressive (IST) and anti‐fibrotic therapies available. However, their real‐world use remains unclear. Objectives To analyze treatment trends and the effect of IST and anti‐fibrotic therapies on ILD progression ...

Inosine triphosphate pyrophosphatase activity as a potential predictor of methotrexate remission in juvenile idiopathic arthritis

Arthritis &Rheumatology, Accepted Article.
Background Methotrexate (MTX) is the first‐line therapy for juvenile idiopathic arthritis (JIA), but up to 40% of patients don't respond. Low inosine‐triphosphate‐pyrophosphatase (ITPA) activity has been associated with reduced clinical remission. We investigated ITPA role and the underlying mechanisms in vitro.

Insights from meta‐analysis for efficient docosahexaenoic acid production in thraustochytrids through advanced cultivation and fermentation strategies

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This systematic review examines strategies for docosahexaenoic acid (DHA) production by thraustochytrids, focusing on cultivation techniques, fermentation technologies, and carbon/nitrogen optimization to increase productivity. Among 169 eligible articles, the 100 most productive studies (0.7–10.3 g DHA L−1 per day) were analyzed. Quantitative

Values of Lucas Sequences Modulo Primes

Rocky Mountain Journal of Mathematics, 2003
Let \(F_n\) denote the Fibonacci numbers. It is very easy to show that primes \(p \neq 5\) divide \(F_{p \pm 1}\), but finding the correct sign involves a piece of quadratic reciprocity. \textit{M. Ward} [Pac. J. Math. 11, 379--386 (1961; Zbl 0112.26904)] has observed that the question which primes divide \(F_{(p \pm 1)/k}\) for \(k = 2, 3, 4 \ldots ...

A pipeline crisis or a sustainability crisis? Local and national succession planning for headteachers in England

British Educational Research Journal, EarlyView.
Abstract Recruiting and retaining school leaders is a challenge in many systems worldwide. Previous research has identified three distinct ways in which succession planning can be conceptualised and approached: a ‘pipeline’ approach seeks to match supply and demand for the posts that need filling; a ‘pool’ strategy involves proactively identifying and ...

Form flows function: Learner‐centered game Re‐design in a STEM classroom

British Educational Research Journal, EarlyView.
Abstract Re‐designing games facilitates interest‐driven learning and immerses learners in systems thinking. However, there are limited studies exploring how the form and function of tabletop games influence learners' design decisions and learning experiences. To address this gap, we conducted a mixed‐methods study in a STEM classroom in western Canada.
