Pole‐To‐Pole 3D Radial Trajectory Designs Improve Image Quality and Quantitative Parametric Mapping in the Brain and Heart

open access: yesMagnetic 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

open access: yesJournal 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 ...

Hyperbolic Fibonacci Sequence

open access: yesUniversal Journal of Mathematics and Applications, 2019
In this paper, we investigate the hyperbolic Fibonacci sequence and the hyperbolic Fibonacci numbers. Furthermore, we give recurrence relations, the golden ratio and Binet's formula for the hyperbolic Fibonacci sequence and Lorentzian inner product ...

Total Variation Regularized GRACE(‐FO) Inversion

open access: yesJournal 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 ...

Sums of certain products of fibonacci & Lucas numbers-part III [PDF]

open access: yes, 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.

Learnings from Approved Antibody‐Drug Conjugates: Clinical Pharmacology Perspectives

open access: yesThe 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.

Closed forms for certain fibonacci type sums that involve second order products [PDF]

open access: yes, 2017
In this paper, we present closed forms for certain finite sums in which the summand is a product of generalized Fibonacci numbers. We present our results in the form of six theorems that feature a generalized Fibonacci sequence {Wn}, and an accompanying ...

Edge-Disjoint Fibonacci Trees in Hypercube

open access: yesJournal of Computer Networks and Communications, 2014
The Fibonacci tree is a rooted binary tree whose number of vertices admit a recursive definition similar to the Fibonacci numbers. In this paper, we prove that a hypercube of dimension h admits two edge-disjoint Fibonacci trees of height h, two edge ...

Free Fibonacci Sequences

open access: yesJ. Integer Seq., 2014
This paper describes a class of sequences that are in many ways similar to Fibonacci sequences: given n, sum the previous two terms and divide them by the largest possible power of n. The behavior of such sequences depends on n. We analyze these sequences for small n: 2, 3, 4, and 5. Surprisingly these behaviors are very different.

Block scheduling in practice: An optimal decomposition strategy for nonidentical operating rooms

open access: yesDecision 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,
