Quantitative Analysis of the Effect of an Ectopic Beat on the Heart Rate Variability in the Resting Condition

open access: yesFrontiers in Physiology, 2018
The purpose of this study is to quantitatively analyze the effect of an ectopic beat on heart rate variability (HRV) in the time domain, frequency domain, and in a non-linear analysis.

Video Frame Interpolation Based on Symmetric and Asymmetric Motions

open access: yesIEEE Access, 2023
Video frame interpolation is the task to synthesize intermediate frames between consecutive frames to increase the frame rate. Recently, various deep-learning techniques have been proposed to interpolate intermediate frames more reliably.

Fast Context-Adaptive Bit-Depth Enhancement via Linear Interpolation

open access: yesIEEE Access, 2019
To fill in the huge gap between the rapid development of modern display devices with high dynamic range (HDR) and the mainstream media source with a low bit depth of 8, bit-depth enhancement (BDE) that reconstructs high bit-depth images from low bit ...

Missing-data imputation using wearable sensors in heart rate variability [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2020
The objective of this work is to set up a methodology that considers missing data from a connected heartbeat sensor in order to propose a good replacement methodology in the context of heart rate variability (HRV) computation. The framework is a research

On Properties of a Regular Simplex Inscribed into a Ball

open access: yesМоделирование и анализ информационных систем, 2021
Let  $B$ be a Euclidean ball in ${\mathbb R}^n$ and let $C(B)$ be a space of continuos functions $f:B\to{\mathbb R}$ with the uniform norm $\|f\|_{C(B)}:=\max_{x\in B}|f(x)|.$ By $\Pi_1\left({\mathbb R}^n\right)$ we mean a set of polynomials of degree ...

Periodicity-aware similarity-weighted linear interpolation for missing-sample reconstruction in environmental sensor time series

open access: yesArray
Missing samples degrade time-series analysis, forecasting, and decision-making. Linear interpolation is a simple, interpretable, training-free baseline, but it ignores periodic structure commonly present in hourly sensor signals.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane

open access: yesFEBS Letters, EarlyView.
Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

Spatial interpolation using conservative fuzzy reasoning [PDF]

open access: yes, 2001
Spatial interpolation is an important feature of a Geographic Information System, which is the procedure used to estimate values at unknown locations within the area covered by existing observations.
