Tutorial on Empirical Mode Decomposition: Basis Decomposition and Frequency Adaptive Graduation in Non-Stationary Time Series

IEEE Access, 2023
This tutorial explores the class of non-parametric time series basis decomposition methods particularly suited for nonstationary time series known as Empirical Mode Decomposition (EMD). In outlining a statistical perspective of the EMD method, it will be

Forecast of temperature changes in the Altai in the next 50 years based on reconstructed ice core data from Belukha Mountain

Лëд и снег, 2015
Paleotemperature time series reconstructed from δ¹⁸O changes in Belukha ice core were expanded into several heteroperiodic sinusoidal functions with the help of the spectral Fourier analysis.

The Fourier analysis in inhomogeneous media

St. Petersburg Polytechnical University Journal: Physics and Mathematics, 2023
In the paper, the definition and basic properties of the Fourier transform (FT) are discussed. It has been shown with specific examples that integral solutions of the model inhomogeneous equation, the nonstationary Cauchy problem on an inhomogeneous ...

The scale levels identification for the plowland topography organization

Бюллетень Почвенного института им. В.В. Докучаева, 2019
The identification of factor and indicational features, which are characterized by the high informativity and field of view in relation to the soil cover organization, plays a very important role in the soil mapping.

Experimental forecast of thermal conditions in the South Kuril region in summer by modified Fourier method

Известия ТИНРО, 2021
Time series of air temperature and sea surface temperature in South Kuril region in July and August are extrapolated to 2020–2024 using modified method of Fourier decomposition. Both cyclic harmonic components and linear trend are accounted.

ZW4864‐mediated inhibition of the β‐catenin/BCL9/BCL9L complex reveals therapeutic potential in bladder cancer

Molecular Oncology, EarlyView.
BCL9 and BCL9L drive bladder cancer progression by enhancing β‐catenin signaling, promoting proliferation, migration, invasion, and organoid growth. Genetic depletion of BCL9(L) suppresses malignant phenotypes, while pharmacological disruption of the β‐catenin/BCL9(L) complex with ZW4864 inhibits canonical Wnt signaling and tumor‐associated cellular ...

A light‐triggered Time‐Resolved X‐ray Solution Scattering (TR‐XSS) workflow with application to protein conformational dynamics

FEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering captures how proteins change shape in real time under near‐native conditions. This article presents a practical workflow for light‐triggered TR‐XSS experiments, from data collection to structural refinement. Using a calcium‐transporting membrane protein as an example, the approach can be broadly applied to study ...
