The class of Lucas-Lehmer polynomials

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2016
In this paper we introduce a new sequence of polynomials, which follow the same recursive rule of the well-known Lucas-Lehmer integer sequence. We show the most important properties of this sequence, relating them to the Chebyshev polynomials of the first and second kind.

Roasting‐Induced Changes in the Chemical Composition, Fatty Acid Profile, and Bioactive Properties of Kaluteh Date Pits

open access: yesFood Science &Nutrition, Volume 14, Issue 11, November 2026.
Kaluteh date pits (≈10% of fruit weight), a major processing by‐product, are rich in carbohydrates (74.92%) and fat (9.30%), with lauric and oleic acids as the predominant fatty acids. Roasting reduced moisture to 4.05% and, combined with RSM‐optimized extraction (63°C, 2.03 h, SSR 0.017 g/mL), yielded extracts with TPC = 14.8 mg GAE/g and DPPH ...

Bivariate Fibonacci and Lucas Like Polynomials [PDF]

open access: yes, 2016
In this article, we study the generalized bivariate Fibonacci (GBF) and generalized bivariate Lucas (GBL) polynomials from specifying p(x,y) and q(x,y), classical bivariate Fibonacci and Lucas polynomials ((p(x,y)=x and q(x,y)=y).

Induction Signals From Europa's Subsurface Ocean: Contributions of Time Variations in the Plasma Interaction

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 11, November 2026.
Abstract The magnetic perturbations generated by Europa's plasma interaction undergo oscillatory variations since Jupiter's magnetospheric current sheet periodically sweeps across the moon. We determine the inductive response of Europa's subsurface ocean to this excitation signal and compare it to the field induced by the time‐varying yet locally ...

On Sequences of Numbers and Polynomials Defined by Linear Recurrence Relations of Order 2

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2009
Here we present a new method to construct the explicit formula of a sequence of numbers and polynomials generated by a linear recurrence relation of order 2.

Establishing a Biophotonic Signature of Brain Ageing

open access: yesAging Cell, Volume 25, Issue 11, November 2026.
If we excite autofluorescence from brains with a 488 nm laser, young brain autofluorescence shows blue‐shifted spectra; aged brain autofluorescence shows red‐shifted spectra. This spectral shift is predicted by plasma SM32:2 levels. These signals allow unbiased distinction of an ageing from a young brain.

Updated Scientific Opinion on the risks for animal and human health related to the presence of phomopsins in feed and food

open access: yesEFSA Journal, Volume 24, Issue 11, November 2026.
Abstract The EFSA CONTAM Panel assessed the risks for animal and human health related to the presence of phomopsins in feed and food. Lupins are considered the main source of phomopsins. Since the previous CONTAM Panel 2012 Opinion on phomopsins, new studies investigated the structural diversity of phomopsins.
