Organoids in pediatric cancer research

open access: yesFEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Search for the optimal smoothing method to improve S/N in cosmic maser spectra

open access: yesOpen Astronomy
In this article, a number of smoothing methods were investigated to enhance the signal-to-noise (S/N) ratio of diverse methanol maser spectral data, encompassing variations in signal strength, multiplicity of peaks, and spectral complexity.

Kriging-Weighted Laplacian Kernels for Grayscale Image Sharpening

open access: yesIEEE Access, 2022
Sharpening filters are used to highlight fine image details, including object edges. However, sharpening filters are very specific to different types of images as they may create undesired edge effects, over-highlight fine details, or emphasize noise ...

Convolution powers in the operator-valued framework

open access: yes, 2011
We consider the framework of an operator-valued noncommutative probability space over a unital C*-algebra B. We show how for a B-valued distribution \mu one can define convolution powers with respect to free additive convolution and with respect to ...

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.

Optical Design of a Smart-Pixel-Based Optical Convolutional Neural Network

open access: yesOptics
We designed lens systems for a smart-pixel-based optical convolutional neural network (SPOCNN) using optical software to analyze image spread and estimate alignment tolerance for various kernel sizes.

The Fourier transform and convolutions generated by a differential operator with boundary condition on a segment

open access: yes, 2013
We introduce the concepts of the Fourier transform and convolution generated by an arbitrary restriction of the differentiation operator in the space $L_{2}(0,b).$ In contrast to the classical convolution, the introduced convolution explicitly depends on

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Remarks on the Generalized Fractional Laplacian Operator

open access: yesMathematics, 2019
The fractional Laplacian, also known as the Riesz fractional derivative operator, describes an unusual diffusion process due to random displacements executed by jumpers that are able to walk to neighbouring or nearby sites, as well as perform excursions ...

Two Convolution Transforms which are Inverted by Convolutions [PDF]

open access: yesProceedings of the American Mathematical Society, 1963
Abstract : Mathematical research concerning the inversion of a convolution transform in which the kernel is a Legendre polynomial is presented. Classes of integral equations of the sort studied here arise in the determination of solutions of certain velocity-potential problems in aerodynamics. (Author)
