Structure and Computation

open access: yesNoûs, EarlyView.
ABSTRACT It is a truism of mathematics that differences between isomorphic number systems are irrelevant to arithmetic. This truism is deeply rooted in the modern axiomatic method and underlies most strands of arithmetical structuralism, the view that arithmetic is about some abstract number structure.

A Class of Convergent Series with Golden Ratio Based on Fibonacci Sequence [PDF]

open access: yesSahand Communications in Mathematical Analysis, 2019
In this article, a class of convergent series based on Fibonacci sequence is introduced for which there is a golden ratio (i.e. $frac{1+sqrt 5}{2}),$ with respect to convergence analysis.

Single‐Shot 2D Radial Echo Planar Imaging for Functional MRI

open access: yesMagnetic Resonance in Medicine, Volume 96, Issue 3, Page 1245-1260, September 2026.
ABSTRACT Purpose To develop a novel single‐shot radial echo planar imaging (ss‐rEPI) technique for rapid, distortion‐free brain imaging in functional MRI experiments. Methods Radial multi‐gradient echo (radial mGRE) data were acquired on a 3T clinical scanner using a 2D ss‐rEPI readout with small golden‐angle rotations between echoes.

LINEARLIZATION OF GENERALIZED FIBONACCI SEQUENCES [PDF]

open access: yesKorean Journal of Mathematics, 2014
Summary: In this paper, we give linearization of generalized Fibonacci sequences \(\{g_n\}\) and \(\{q_n\}\), respectively, defined by Gupta et al. and Edson et al. and use this result to give the matrix form of the \(n\)-th power of a companion matrix of \(\{g_n\}\) and \(\{q_n\}\). Then we re-prove the Cassini's identity for \(\{g_n\}\) and \(\{q_n\}\

Safety, Tolerability, and Pharmacokinetics of GMDTC for Cadmium Poisoning: A Randomized Phase 1a/1b Trial

open access: yesClinical 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 ...

Transformations of Pythagorean triples generated by generalized Fibonacci numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
We present matrices that transform Pythagorean triples arising from generalized Fibonacci sequences into other such triples. We also show that entries in the powers of such matrices can be expressed in terms of generalized Fibonacci sequences.

Dynamic sampling for SAXSTT: towards real‐time measurement adaptation

open access: yesJournal of Synchrotron Radiation, Volume 33, Issue 4, Page 1159-1168, July 2026.
A dynamic sampling strategy is presented to reduce the measurement time required for SAXS tensor tomography while maintaining reconstruction quality.Small‐angle X‐ray scattering tensor tomography (SAXSTT) is a powerful technique for non‐destructive 3D characterization of nanoscale structures by reconstructing q‐resolved reciprocal space maps.

Renormalization techniques for inflation systems and some of their applications

open access: yesActa Crystallographica Section A, Volume 82, Issue 4, Page 294-304, July 2026.
In this work, renormalization methods for quantities related to the diffraction of inflation systems are surveyed.Exact renormalization techniques are important and powerful, particularly for inflation‐generated systems. We review recent results in this direction.

Fragment‐Based Design of Targeted Covalent Inhibitors: The Scope and Limitation of Linking Approaches

open access: yesChemMedChem, 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
