Sequence-Activated Fluorescent Nanotheranostics for Real-Time Profiling Pancreatic Cancer

open access: yesJACS Au, 2022
Pancreatic ductal adenocarcinoma (PDAC), as one of the most malignant tumors with dense desmoplastic stroma, forms a specific matrix barrier to hinder effective diagnosis and therapy.

Gravity Aided Positioning Based on Real-Time ICCP With Optimized Matching Sequence Length

open access: yesIEEE Access, 2019
The existing real-time iterative closest contour point (ICCP) algorithm uses fixed matching sequence length, which is set according to human experience and cannot obtain the best positioning accuracy on all tracks.

On Lacunary p-Absolutely Summable Fuzzy Real-Valued Double Sequence Space

open access: yesDemonstratio Mathematica, 2014
In this article, we introduce the class of p-absolutely summable fuzzy real valued double sequence (2lp)Fθ We have studied some algebraic properties like solid, symmetric, convergence free, sequence algebra.

On the convergence rates of pairs of adjacent sequences

open access: yesJournal of Numerical Analysis and Approximation Theory, 2020
In this paper we give a suitable definition for the pairs of adjacent (convergent) sequences of real numbers, we present some two-sided estimations which caracterize the order of convergence to its limits of some of these sequences and we give certain ...

Orthogonal families of real sequences [PDF]

open access: yesJournal of Symbolic Logic, 1998
For x, y ϵ ℝω define the inner productwhich may not be finite or even exist. We say that x and y are orthogonal if (x, y) converges and equals 0.Define lp to be the set of all x ϵ ℝω such thatFor Hilbert space, l2, any family of pairwise orthogonal sequences must be countable.

On Gradual Borel Summability Method of Rough Convergence of Triple Sequences of Beta Stancu Operators

open access: yesDera Natung Government College Research Journal, 2023
We define the concept of rough limit set of a triple sequence space of beta Stancu operators of Borel summability of gradual real numbers and obtain the relation between the set of rough limit and the extreme limit points of a triple sequence space of ...

On irregularities of distribution of real sequences [PDF]

open access: yesProceedings of the National Academy of Sciences, 1981
A natural measure of the amount of unavoidable clustering that must occur in any bounded infinite sequence of real numbers is studied. We determine the extreme value for this measure and exhibit sequences that achieve this value.

On certain Banach spaces of difference sequences of fuzzy real numbers [PDF]

open access: yesMaejo International Journal of Science and Technology, 2014
Some sets of difference sequences of fuzzy real numbers which have Banach subspaces are introduced and investigated. Further, it is shown that these subspaces are isometric with some subsets of the sets of null, convergent and bounded sequences of fuzzy
