A Note on the Kadec-Klee Property

open access: yesAxioms
The objective of this paper is to rigorously define the Kadec-Klee property for modular spaces endowed with a sequential convergence structure, and to demonstrate that this property leads to normal structure in such spaces.

Acoustics of Sequential Spaces [PDF]

open access: yes, 2022
“Sequential spaces” are spatial systems comprising multiple spaces in sequence connected by openings, common in public spaces with crowd transit (e.g., museums, shopping malls, and transportation hubs).

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Completeness in Quasi-Pseudometric Spaces—A Survey

open access: yesMathematics, 2020
The aim of this paper is to discuss the relations between various notions of sequential completeness and the corresponding notions of completeness by nets or by filters in the setting of quasi-metric spaces.

The problem of space invariance for sequential machines

open access: yesInformation and Computation, 1988
The paper presents a detailed discussion of the following invariance thesis: There exists a standard class of machines (including Turing machines and usual RAM's) with the property that models in this class simulate each other with polynomially overhead in time and with constant factor overhead in space.

Sequential S?-compactness in L-topological spaces

open access: yes, 2017
In this paper, a new notion of sequential compactness is introduced in L-topological spaces, which is called sequentially S?-compactness. If L = [0, 1], sequential ultra-compactness, sequential N-compactness and sequential strong compactness imply ...

TRAIL‐PEG‐Apt‐PLGA nanosystem as an aptamer‐targeted drug delivery system potential for triple‐negative breast cancer therapy using in vivo mouse model

open access: yesMolecular Oncology, EarlyView.
Aptamers are used both therapeutically and as targeting agents in cancer treatment. We developed an aptamer‐targeted PLGA–TRAIL nanosystem that exhibited superior therapeutic efficacy in NOD/SCID breast cancer models. This nanosystem represents a novel biotechnological drug candidate for suppressing resistance development in breast cancer.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

open access: yesMolecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Rarely convergent sequences in topological spaces

open access: yesKuwait Journal of Science, 2020
In this work, by using rare sets, we introduce a new type of convergence in topological spaces, called rare convergence, which is weaker than ordinary convergence.
