Powers in a class of A-strict standard episturmian words [PDF]
, 2007 This paper concerns a specific class of strict standard episturmian words whose directive words resemble those of characteristic Sturmian words. In particular, we explicitly determine all integer powers occurring in such infinite words, extending recent ...

On Integer Numbers with Locally Smallest Order of Appearance in the Fibonacci Sequence
International Journal of Mathematics and Mathematical Sciences, 2011 Let Fn be the nth Fibonacci number. The order of appearance z(n) of a natural number n is defined as the smallest natural number k such that n divides Fk. For instance, for all n=Fm≥5, we have z(n−1)>z(n)

Skew shapes, Ehrhart positivity, and beyond
Proceedings of the London Mathematical Society, Volume 133, Issue 2, August 2026.Abstract A classical result by Kreweras (1965) allows one to compute the number of plane partitions of a given skew shape and bounded parts as certain determinants. We prove that these determinants expand as polynomials with nonnegative coefficients.

Sums of certain products of fibonacci & Lucas numbers-part III [PDF]
, 2017 For the Fibonacci numbers, the summation formula σnk=1 Fk2=FnFn+1is well-known. Its charm lies in the fact that the right side is a product of terms from the Fibonacci sequence.

Clinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 160-167, July 2026.Cadmium exposure causes serious health consequences; however, there is no clinically approved antidote for cadmium poisoning. This Phase 1a/1b trial aimed to investigate safety, tolerability, and pharmacokinetics of Sodium (S)‐2‐(dithiocarboxylato((2S,3R,4R,5R)‐2,3,4,5,6‐pentahydroxyhexyl) amino)‐4‐(methylthio) butanoate (GMDTC), a novel chelating ...

On the Frobenius Number of Fibonacci Numerical Semigroups
, 2007 In this paper we compute the Frobenius number of certain Fibonacci numerical semigroups, that is, numerical semigroups generated by a set of Fibonacci numbers, in terms of Fibonacci ...

Fibonacci Numbers of Generalized Fibonacci Graphs
Mediterranean Journal of MathematicsAbstract The Fibonacci number of a graph, introduced by Prodinger and Tichy, is defined as the total number of independent vertex sets, including the empty set, and it is closely related to the Merrifield–Simmons index in chemical graph theory.

ChemMedChem, Volume 21, Issue 10, 27 May 2026.This paper by Kollár et al. reports a covalent fragment linking study against the SARS‐CoV‐2 main protease (3CLPro). Beginning with inactive fragment hits, the application of rational linker design enabled the generation of reversible covalent inhibitors exhibiting low micromolar potency. The study details some general limitations and best practices of

Journal of Magnetic Resonance Imaging, Volume 63, Issue 5, Page 1435-1447, May 2026.ABSTRACT Background Non‐contrast renal MR angiography (MRA) is valuable for patients who cannot receive contrast agents or when avoiding radiation is desired. However, the conventional inflow inversion recovery (IFIR) method is limited by incomplete background suppression, venous contamination, and motion sensitivity.
