A Novel Computer-Aided Diagnostic System for Early Detection of Diabetic Retinopathy Using 3D-OCT Higher-Order Spatial Appearance Model [PDF]

open access: yesDiagnostics, 2022
Early diagnosis of diabetic retinopathy (DR) is of critical importance to suppress severe damage to the retina and/or vision loss. In this study, an optical coherence tomography (OCT)-based computer-aided diagnosis (CAD) method is proposed to detect DR ...

On the Local Minima of the Order of Appearance Function [PDF]

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2015
The order of appearance z(n) of the positive integer n is the smallest positive integer k such that n divides Fk, the kth member of the Fibonacci sequence. In this paper, we improve upon some results from (Marques, 2011) concerning local minima of z(n).

On the Parity of the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2021
Let (Fn)n≥0 be the Fibonacci sequence. The order of appearance function (in the Fibonacci sequence) z:Z≥1→Z≥1 is defined as z(n):=min{k≥1:Fk≡0(modn)}.

On Fixed Points of Iterations Between the Order of Appearance and the Euler Totient Function

open access: yesMathematics, 2020
Let Fn be the nth Fibonacci number. The order of appearance z(n) of a natural number n is defined as the smallest positive integer k such that Fk≡0(modn).

On Periodic Points of the Order of Appearance in the Fibonacci Sequence

open access: yesMathematics, 2020
Let ( F n ) n ≥ 0 be the Fibonacci sequence. The order of appearance z ( n ) of an integer n ≥ 1 is defined by z ( n ) = min { k ≥ 1 : n ∣ F k } .

Appearance-Order-Based Schema Matching

open access: yesJournal of Computing Science and Engineering, 2014
Schema matching is widely used in many applications, such as data integration, ontology merging, data warehouse and dataspaces. In this paper, we propose a novel matching technique that is based on the order of attributes appearing in the schema structure of query results.

Multi-Target Tracking Based on High-Order Appearance Feature Fusion

open access: yesIEEE Access, 2019
Multi-target tracking (MTT) is among the fundamental problems in the field of video analysis and monitoring. In the tracking-by-detection framework, data association is one of the most important and difficult problems.

The Proof of a Conjecture Related to Divisibility Properties of z(n)

open access: yesMathematics, 2021
The order of appearance of n (in the Fibonacci sequence) z(n) is defined as the smallest positive integer k for which n divides the k—the Fibonacci number Fk. Very recently, Trojovský proved that z(n) is an even number for almost all positive integers n (
