Entropy Measures in Analysis of Head up Tilt Test Outcome for Diagnosing Vasovagal Syncope

open access: yesEntropy, 2018
The paper presents possible applications of entropy measures in analysis of biosignals recorded during head up tilt testing (HUTT) in patients with suspected vasovagal syndrome.

A Numerical–Experimental Approach for Multi‐Matrix Fiber‐Reinforced Plastics Characterization Using Finite Element Model Updating

open access: yesAdvanced Engineering Materials, EarlyView.
A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Vasodepressor syncope and the diagnostic accuracy of the head-up tilt test with sublingual glyceryl trinitrate

open access: yes, 2003
Thirteen syncopal subjects and thirteen asymptomatic controls were examined by head-up tilt (HUT) with and without sublingual GTN.Adding GTN to HUT improved the sensitivity of the test (8 % to 46%) but decreasedPeter Athanasos, Daniel Sydenham, Jenny ...

Ontology‐Aligned Structuring and Reuse of Multimodal Materials Data and Workflows Toward Automatic Reproduction

open access: yesAdvanced Engineering Materials, EarlyView.
Reproduction of stacking fault energy calculations from literature with a semi‐automated large language model‐assisted extraction procedure: extraction of simulation protocol, atomistic structures, computational parameters, and reported results, ontology alignment, knowledge graph construction and, finally, recomputation forvalidation.

Supplemental Video 1: Veno-arterial bundles and valve recruitment during head-up tilt.

open access: yes, 2023
Examples of deep femoral vein valve recruitment during -6 degree head-down tilt, supine rest, 20 degree head-up tilt, and 40 degree head-up tilt. SFA = superficial femoral artery, DFV = deep femoral vein.
