The characterizations of upper approximation operators based on special coverings

Open Mathematics, 2017
In this paper, we discuss the approximation operators apr¯NS${\overline {apr} _{NS}}$ and apr¯S${\overline {apr} _S}$ which are based on NS(U) and S.

dUTPase is essential in zebrafish development and possesses several single‐nucleotide variants with pronounced structural and functional consequences

FEBS Open Bio, EarlyView.
dUTPases are involved in balancing the appropriate nucleotide pools. We showed that dUTPase is essential for normal development in zebrafish. The different zebrafish genomes contain several single‐nucleotide variations (SNPs) of the dut gene. One of the dUTPase variants displayed drastically lower protein stability and catalytic efficiency as compared ...

Some remarks on the Hausdorff measure of the Cantor set

SHS 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 ...

Chainability and Hemmingsen\u27s Theorem [PDF]

, 2006
On the surface, the definitions of chainability and Lebesgue covering dimension ⩽1 are quite similar as covering properties. Using the ultracoproduct construction for compact Hausdorff spaces, we explore the assertion that the similarity is only skin ...

Matroids with the Circuit Cover Property

European Journal of Combinatorics, 1999
Let \(M\) be a binary matroid and \(p: M \mapsto Z^+\) be a weight on \(M\). A family \(\mathcal F\) of circuits of \(M\) is called a faithful circuit cover of \(M\) with respect to \(p\) if every element \(e\) of \(M\) is contained in precisely \(p(e)\) members of \(\mathcal F\).

Tumor‐stromal crosstalk and macrophage enrichment are associated with chemotherapy response in bladder cancer

FEBS Open Bio, EarlyView.
Chemoresistance in bladder cancer: Macrophage recruitment associated with CXCL1, CXCL5 and CXCL8 expression is characteristic of Gemcitabine/Cisplatin (Gem/Cis) Non‐Responder tumors (right side) while Responder tumors did not show substantial tumor‐stromal crosstalk (left side). All biological icons are attributed to Bioicons: carcinoma, cancerous‐cell‐

HOMFLY polynomials of some links(某些链环的HOMFLY多项式)

Zhejiang Daxue xuebao. Lixue ban
This paper systematically investigates the properties and computational formulae of HOMFLY polynomials for covering links. It shows that each complement of the covering link is a nontrivial knot, and investigates the properties of the covering links ...

Effects of soil covering on bacterial communities and C/N functional genes during phytoremediation of copper tailings

Ecotoxicology and Environmental Safety
Copper tailings, a mining waste, pose environmental threats, and phytoremediation commonly employs soil covering to improve substrate properties and promote vegetation recovery. This study was conducted at the Yangshanchong Tailings Reservoir in Tongling

Magnetic properties and giant magnetoimpedance of surface modified Co-based amorphous ribbons with carbon covering

EPJ Web of Conferences, 2018
Fe3Co66Cr3Si16B12 and Fe6Co60Ni10Si14B10 amorphous ribbons were surface modified in toluene at room temperature. Such a treatment resulted in deposition of thin carbon-based layer.

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

FEBS 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‐
