Singular integrals on Sierpinski gaskets [PDF]
We construct a class of singular integral operators associated with homogeneous Calder n-Zygmund standard kernels on $d$-dimensional, $d <1$, Sierpinski gaskets $E_d$. These operators are bounded in $L^2( _d)$ and their principal values diverge $ _d$ almost everywhere, where $ _d$ is the natural (d-dimensional) measure on $E_d$.

The general space-time evolution of the scattering of an incident acoustic plane wave pulse by an arbitrary configuration of targets is treated by employing a recently developed non-singular boundary integral method to solve the Helmholtz equation in the

L P estimates for the maximal singular integral in terms of the singular integral [PDF]
This paper continues the study, initiated in the works {MOV} and {MOPV}, of the problem of controlling the maximal singular integral $T^{*}f$ by the singular integral $Tf$. Here $T$ is a smooth homogeneous Calder n-Zygmund singular integral operator of convolution type.

Analogue Sochocky formulae for integral operators with additional logarithmic singularity
In this paper we prove the limit formulas for singular integrals of the form. Limit values of such integrals are expressed in terms of singular integral operators and also integral operators.

Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Approximation theorems for the Gauss-Weierstrass singular integral [PDF]
In this paper we present three approximation theorems for the Gauss-Weierstrass singular integral in the spaces Lp (1 ≤ p < ∞), C and Hölder spaces. Those theorems generalize and improve the results for the Gauss-Weierstrass singular integral given in ...

Solutions for singular Volterra integral equations
We consider the system of Volterra integral equations $$ \begin{array}{l} u_i(t)=\int_{0}^{t}g_i(t,s)[P_i(s,u_1(s),u_2(s),\cdots, u_n(s)) + Q_i(s,u_1(s),u_2(s),\cdots, u_n(s))]ds, t\in [0,T],1\leq i\leq n \end{array} $$ where $T>0$ is fixed and the ...

Gut alterations in a chronic kidney disease rat model with diet‐induced vascular calcification
Chronic kidney disease (CKD) patients often suffer from intestinal and/or mineral and bone disorders. Using a rat model, we showed that uremic vascular calcification is associated with gut barrier alterations (decreased gut mucus production and Nlrp6 gene expression, increased gut inflammation), and plasma retention of gut‐origin uremic toxins (indoxyl
