Elementary sequences, sub-Fibonacci sequences

open access: yesDiscrete Applied Mathematics, 1993
AbstractRecent research in uniqueness of representability for finite measurement structures has identified a number of novel finite integer sequences. One of the simplest, called an elementary sequence, is a nondecreasing integer sequence x1,x2,…,xn with x1=x2=1 and, for all k> 2, if xk > 1 then xk=i+j for distinct i,j < k. We investigate combinatorial

An adaptive block‐wise prediction error‐based (AdaBPE) reversible data hiding in encrypted images for medical image transmission

open access: yesCAAI Transactions on Intelligence Technology, EarlyView.
Abstract Life expectancy has improved with new‐age technologies and advancements in the healthcare sector. Though artificial intelligence (AI) and the Internet of Things (IoT) are revolutionising smart healthcare systems, security of the healthcare data is always a concern.

Almost Repdigit k-Fibonacci Numbers with an Application of k-Generalized Fibonacci Sequences

open access: yesMathematics, 2023
In this paper, we define the notion of almost repdigit as a positive integer whose digits are all equal except for at most one digit, and we search all terms of the k-generalized Fibonacci sequence which are almost repdigits. In particular, we find all k-

Hopcroft's automaton minimization algorithm and Sturmian words [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2008
This paper is concerned with the analysis of the worst case behavior of Hopcroft's algorithm for minimizing deterministic finite state automata. We extend a result of Castiglione, Restivo and Sciortino.

High‐resolution X‐ray scanning with a diffuse Huffman‐patterned probe to reduce radiation damage

open access: yesJournal of Synchrotron Radiation, EarlyView.
This paper introduces high‐resolution imaging using diffuse probes, which allow for lower energy deposition per unit area per unit time, by encoding Huffman‐like patterns onto them, enabling a tighter impulse response. The approach, demonstrated in X‐ray imaging, involves using specially fabricated masks to shape the probe and recover sharp object ...

3D MERMAID: 3D Multi‐shot enhanced recovery motion artifact insensitive diffusion for submillimeter, multi‐shell, and SNR‐efficient diffusion imaging

open access: yesMagnetic Resonance in Medicine, Volume 93, Issue 6, Page 2311-2330, June 2025.
Abstract Purpose To enhance SNR per unit time of diffusion MRI to enable high spatial resolution and extensive q‐sampling in a feasible scan time on clinical scanners. Methods 3D multi‐shot enhanced recovery motion‐insensitive diffusion (MERMAID) consists of a whole brain nonselective 3D multi‐shot spin‐echo sequence with an inversion pulse immediately

What does a modified-Fibonacci dose-escalation actually correspond to?

open access: yesBMC Medical Research Methodology, 2012
Background In most phase I oncology trials, it is often stated that the dose increments follow a “modified-Fibonacci sequence”. This term, however, is vague.

Iterated Partial Sums of the k-Fibonacci Sequences

open access: yesAxioms, 2022
In this paper, we find the sequence of partial sums of the k-Fibonacci sequence, say, Sk,n=∑j=1nFk,j, and then we find the sequence of partial sums of this new sequence, Sk,n2)=∑j=1nSk,j, and so on.

Fast heuristics for the time‐constrained immobile server problem

open access: yesInternational Transactions in Operational Research, Volume 32, Issue 3, Page 1282-1311, May 2025.
Abstract We propose easy‐to‐implement heuristics for time‐constrained applications of a problem referred to in the literature as the facility location problem with immobile servers, stochastic demand, and congestion, the service system design problem, or the immobile server problem (ISP).
