Novel Expressions for Certain Generalized Leonardo Polynomials and Their Associated Numbers

Axioms
This article introduces new polynomials that extend the standard Leonardo numbers, generalizing Fibonacci and Lucas polynomials. A new power form representation is developed for these polynomials, which is crucial for deriving further formulas.

The Politics of Framing the Student Problem: Inquiries Into Australian Civics Education, 2006–2024

Australian Journal of Social Issues, EarlyView.
ABSTRACT Recurring debates about civics, the kinds of history that should, and should not, be taught in school, and ‘standards debates’ about the ‘basics’ typically follow on the heels of recurring moral panics about the ‘declining’ state of ‘our’ education system.

Shifting Child Protection Assessments From a Deficit Focus to Assessments Informed by Strengths and Protective Factors: Translating Research Knowledge to Practice

Australian Journal of Social Issues, EarlyView.
ABSTRACT Child protection systems play a critical role in preventing and responding to child maltreatment, yet practices are often predominantly deficit focused. This paper presents a rapid literature review on the strengths, protective factors, and cultural considerations to inform child protection assessment.

New Results on Negative-Indexed Pell Numbers via Matrix Methods

Cumhuriyet Science Journal
In this study, we investigate the Pell and Pell–Lucas numbers sequences and construct matrices whose elements are defined using negative indices of these sequences through Binet’s formula. Identities involving negative-indexed Pell and Pell–Lucas numbers

Minute‐Scale Repeated Metabolic Probing of Living Cells Enabled by Rapid Parahydrogen‐Based Hyperpolarization

Angewandte Chemie International Edition, EarlyView.
Rapid parahydrogen hyperpolarization combined with simple dilution enables biocompatible delivery of hyperpolarized pyruvate to immobilized living cells within ≈1 min. Repeated substrate injections reveal frequency‐dependent metabolic dynamics, introducing a new temporal dimension for hyperpolarized NMR studies of cellular metabolism and enabling rapid

Anomeric Amide Enabled Divergent Synthesis of Unsymmetrical Ureas, Carbamates, Thioesters, and Amides From Aldehydes

Angewandte Chemie International Edition, EarlyView.
An anomeric amide‐enabled divergent aldehyde functionalization sequence provides one‐pot access to unsymmetrical ureas, carbamates, thiocarbamates, thioesters, and amides. Key to this transformation is the formation of N‐Boc‐hydroxamate intermediates, which serve as platforms for orthogonal activation via Lossen‐type rearrangements, single‐electron ...

Sustainable Palm Oil Extraction and Trends in the Use of Green Technologies: State‐of‐the‐Art and Future Directions

Journal of the American Oil Chemists' Society, EarlyView.
ABSTRACT Palm oil, which is extracted from the mesocarp of the fruit of the Elaeis guineensis Jacq. palm tree, is the most widely produced vegetable oil in the world. The extraction of this substance typically utilizes the conventional pressing method, a technique that is advantageous due to its low operating cost and simplified process.
