The solution of multi-scale partial differential equations using wavelets

, 1998
Wavelets are a powerful new mathematical tool which offers the possibility to treat in a natural way quantities characterized by several length scales.

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

Molecular 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.

Hermite–Gauss wavelets: synthesis of discrete forms and investigation of properties

Научно-технический вестник информационных технологий, механики и оптики
Considered new results of studies of eigenvectors and vector functions of discrete and continuous Fourier transforms. It is known that such eigenvectors are products of the Gauss function on Hermite polynomials, a name is proposed for the functions ...

Wavelets transformation: A new method for signal analysis

Vojnotehnički Glasnik, 2000
In this paper a new method for signal analysis - wavelets transformation is presented. We consider basic theoretical assumptions and mathematical foundations, signal representation in time-frequency domain, fast algorithms for practical implementation ...

RIPK4 function interferes with melanoma cell adhesion and metastasis

Molecular Oncology, EarlyView.
RIPK4 promotes melanoma growth and spread. RIPK4 levels increase as skin lesions progress to melanoma. CRISPR/Cas9‐mediated deletion of RIPK4 causes melanoma cells to form less compact spheroids, reduces their migratory and invasive abilities and limits tumour growth and dissemination in mouse models.

From the construction of wavelets based on derivatives of the Gaussian function to the synthesis of filters with a finite impulse response

Научно-технический вестник информационных технологий, механики и оптики
For continuous wavelet transformation, wavelets based on derivatives of the Gauss function are used, and for multiscale analysis, Daubechies wavelets are used.

Multivariate box spline wavelets in higher-dimensional Sobolev spaces

Journal of Inequalities and Applications, 2018
We construct wavelets and derive a density condition of MRA in a higher-dimensional Sobolev space. We give necessary and sufficient conditions for orthonormality of wavelets in Hs(Rd) $H^{s}(\mathbb {R}^{d})$.

Frames of directional wavelets on $n$-dimensional spheres

, 2017
The major goal of the paper is to prove that discrete frames of (directional) wavelets derived from an approximate identity exist. Additionally, a kind of energy conservation property is shown to hold in the case when a wavelet family is not its own ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

Molecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...
