Some remarks on the Hausdorff measure of the Cantor set

open access: yesSHS Web of Conferences, 2016
In this paper, the author further reveals some intrinsic properties of the Cantor set. By the properties, the author gives a new method for calculating the exact value of the Hausdorff measure of the Cantor set, and shows the facts that each covering ...

D-spaces and covering properties

open access: yesTopology and its Applications, 2005
A neighbourhood assignment on a topological space is a mapping \(\phi\) of \(X\) into the topology \(\tau\) of \(X\) such that \(x\in \phi(x)\) for each \(x \in X\). A space \(X\) is a D-space if, for every neighbourhood assignment \(\phi\) on \(X\), there exists a locally finite (in \(X\)) subset \(A\) of \(X\) such that the family \(\phi(A)\) covers \

Spatial biology in cancer epigenetics

open access: yesMolecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Tailoring silk-based covering material with matched mechanical properties for vascular tissue engineering

open access: yesScientific Reports
Vascular covered stents play a significant therapeutic role in cardiovascular diseases. However, the poor compliance and biological inertness of commercial materials cause post-implantation complications.

Soft Covering Based Rough Sets and Their Application

open access: yesThe Scientific World Journal, 2014
Soft rough sets which are a hybrid model combining rough sets with soft sets are defined by using soft rough approximation operators. Soft rough sets can be seen as a generalized rough set model based on soft sets.

ADP‐ribosylation: An emerging regulator of the epigenome

open access: yesMolecular Oncology, EarlyView.
ADP‐ribosylation has emerged as a dynamic epigenetic signaling mechanism that modifies histones and chromatin‐associated proteins. Through coordinated PARylation and MARylation, it integrates with other histone modifications to regulate chromatin structure, transcription factor activity, and gene expression, influencing genome function and disease ...

Predictive and prognostic biomarkers of Bacillus Calmette‐Guérin therapy failure in bladder cancer patients: A systematic review

open access: yesMolecular Oncology, EarlyView.
High‐risk bladder cancer is typically treated with Bacillus Calmette‐Guérin (BCG), but 30–40% of patients relapse. No FDA‐ or CE‐approved biomarkers currently predict or prognosticate BCG failure. We systematically reviewed the literature and identified 72 eligible studies, revealing several promising biomarkers associated with BCG treatment response ...

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

open access: yesFEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

Seeding Performances of No-Till Seeders Equipped with Different Furrow Openers, Covering Components and Forward Speeds for Winter Wheat

open access: yesJournal of Agricultural Sciences, 2012
In the no-till method, seeds are placed in rows opened by furrow openers that can work under stubble field conditions, and are covered with soil and plant residue using covering components.

Monotone covering properties and properties they imply

open access: yesTopology and its Applications, 2016
From the abstract: We study properties of spaces that were proven in an earlier paper of \textit{T. Chase} and \textit{G. Gruenhage} [Topology Appl. 160, No. 1, 45--49 (2013; Zbl 1264.54039)] to follow from monotonic metacompactness. We show that all of the results of that earlier paper that follow from the monotonic covering property follow just from ...
