Predicting Future Incidences of Cardiac Arrhythmias Using Discrete Heartbeats from Normal Sinus Rhythm ECG Signals via Deep Learning Methods

open access: yesDiagnostics, 2023
This study aims to compare the effectiveness of using discrete heartbeats versus an entire 12-lead electrocardiogram (ECG) as the input for predicting future occurrences of arrhythmia and atrial fibrillation using deep learning models.

Estimation of net surface radiation from eddy flux tower measurements using artificial neural network for cloudy skies

open access: yesSustainable Environment Research, 2016
Accurate knowledge of net surface radiation (NSR) is required to understand the soil-vegetation-atmosphere feedbacks. However, NSR is seldom measured due to the technical and economical limitations associated with direct measurements.

NSR superstring measures revisited [PDF]

open access: yesJournal of High Energy Physics, 2008
Review of remarkable progress in evaluating of NSR superstring measures, originated by E.D'Hoker and D.Phong. These recent results are presented in the old-fashioned form, which allows to highlight the options that have been overlooked in original considerations in late 1980's.

4D higher spin black holes with nonlinear scalar fluctuations

open access: yesJournal of High Energy Physics, 2017
We construct an infinite-dimensional space of solutions to Vasiliev’s equations in four dimensions that are asymptotic to AdS spacetime and superpose massless scalar particle modes over static higher spin black holes. Each solution is obtained by a large

Forest under stress: responses and recovery of water relations across scales during the compound drought in summer 2022. [PDF]

open access: yesNew Phytol
A schematic showing the links of tree‐scale (root‐, stem‐, and leaf‐level) and ecosystem‐scale water relations during the CSAD at CH‐Lae. Summary The summer of 2022 was characterized by compound soil and atmospheric drought (CSAD; low soil water content, SWC, and high vapor pressure deficit, VPD) in Central Europe, threatening forest carbon ...

A Statistical Arima Model to Predict Arctic Environment for NSR Shipping

open access: yes, 2021
Safe and energy-efficient ship navigation along the Northern Sea Route (NSR) requires reliable sea ice concentration (SIC) information. However, the SIC forecast used to assist NSR shipping is often inaccurate.

A nonlinear analysis of cardiovascular diseases using multi-scale analysis and generalized hurst exponent

open access: yesHealthcare Analytics, 2023
Congestive heart failure (CHF) and arrhythmia (ARR) are common heart diseases that affect a growing population of patients worldwide. In this work, we employ multi-scale analysis (MSA) to estimate generalized Hurst exponent (GHE) from electrocardiogram ...

NSR-I by position over individual thresholds.

open access: yes, 2020
The x-axis shows individual need thresholds, the y-axis the NSR-I for individual observations. The central player never was assigned a threshold of 12 points (see Table 1 for list of thresholds).
