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)

Magnetic Resonance in Medicine, Volume 95, Issue 5, Page 2627-2643, May 2026.ABSTRACT Purpose To design 3D radial spiral phyllotaxis trajectories aimed at removing phase inconsistencies, improving image quality, and enhancing parametric mapping accuracy by acquiring nearly opposing spokes starting from both hemispheres in 3D radial k‐space. Methods Two 3D radial trajectories, pole‐to‐pole and continuous spiral phyllotaxis, were

Mind the Gap: Linking Refactorings and Code Smells in Elixir
Journal of Software: Evolution and Process, Volume 38, Issue 5, May 2026.ABSTRACT Elixir is a functional programming language increasingly used in the industry to develop scalable and fault‐tolerant concurrent systems more easily and with fewer computational resources. In previous studies, we cataloged 35 code smells and 82 refactorings tailored for this language, validating them with over 300 experienced developers ...

Total Variation Regularized GRACE(‐FO) Inversion
Journal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.Abstract Gravity estimation from satellite‐satellite tracking missions such as GRACE(‐FO) is an ill‐posed inverse problem. The conventional approach to regularized inversion of GRACE(‐FO) measurements uses L2 ${L}_{2}$‐Tikhonov regularization with a heuristic constraint matrix derived based on knowledge of spatiotemporal distribution of the signal ...

Learnings from Approved Antibody‐Drug Conjugates: Clinical Pharmacology Perspectives
The Journal of Clinical Pharmacology, Volume 66, Issue 4, April 2026.Abstract Over the past decade, antibody‐drug conjugates (ADCs) have emerged as promising anti‐cancer therapeutics, with twelve ADCs approved by the FDA. This review evaluates trends in these ADCs, stratified by payloads on doses studied from first‐in‐human (FIH) trials through approval and post‐marketing.

Block scheduling in practice: An optimal decomposition strategy for nonidentical operating rooms
Decision Sciences, Volume 57, Issue 2, Page 95-116, April 2026.Abstract We develop and implement a Master Surgery Schedule for a real‐life hospital, assigning operating room (OR) time to surgical specialties over a multi‐week horizon. Through action research, we identify a critical operational challenge: the issue of split blocks. Split blocks allow two specialties to share an OR on the same day—one in the morning,

Hausdorff dimension of double‐base expansions and binary shifts with a hole
Bulletin of the London Mathematical Society, Volume 58, Issue 4, April 2026.Abstract For two real bases q0,q1>1$q_0, q_1 > 1$, a binary sequence i1i2⋯∈{0,1}∞$i_1 i_2 \cdots \in \lbrace 0,1\rbrace ^\infty$ is the (q0,q1)$(q_0,q_1)$‐expansion of the number πq0,q1(i1i2⋯)=∑k=1∞ikqi1⋯qik.$$\begin{equation*} \pi _{q_0,q_1}(i_1 i_2 \cdots) = \sum _{k=1}^\infty \frac{i_k}{q_{i_1} \cdots q_{i_k}}.

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.

Another type of generalized fibonacci series
Semina: Ciências Exatas e Tecnológicas, 2004 The Fibonacci sequence, with many applications and occurrences in nature and arts is discussed in the present work. It is considered a generalization of the Fibonacci series by the introduction of a real coefficient in the recurrence relation.
