A Single Volatile VO2 Memristor Enabling Neuromorphic Perception, Learning, and Computing

Advanced Electronic Materials, EarlyView.
A single volatile VO2 memristor fabricated via atomic layer deposition is demonstrated as a multifunctional neuromorphic device enabled by intrinsic threshold‐switching dynamics. The device reproduces neuron‐like integration and firing, short‐timescale associative learning, temporal ECG pattern classification, and nociceptive responses to electrical ...

Implantable Systems for Cardiovascular Treatment and Monitoring: Comparative Insights From Intracardiovascular and Extracardiovascular Technologies

Advanced Intelligent Systems, EarlyView.
A unifying device–cardiovascular interface framework is presented to classify implantable cardiovascular technologies as intracardiovascular blood‐contacting systems or extracardiovascular tissue‐only and blood‐handling architectures. Cross‐class comparison across shared semiquantitative criteria, including blood‐contact burden, biomimicry ...

Surgical Repair of Post-Infarct True Posterobasal Ventricular Aneurysm with Mitral Valve Replacement and Coronary Revascularization: a Case Report [PDF]

Journal of Tehran University Heart Center, 2012
Post-infarction ventricular aneurysm is a complication of myocardial infarction. While the involvement of the anterior wall is quite common, posterobasal left ventricular aneurysm is a rare clinical complication in this setting.

Left ventricular concentric geometry predicts incident diabetes mellitus independent of established risk factors in the general population: the Copenhagen City Heart Study

Cardiovascular Diabetology, 2019
Background Subtle impairments in left ventricular (LV) function and geometry are common findings in individuals with diabetes. However, whether these impairments precede the development of diabetes mellitus (DM) is not entirely clear.

A Novel Constitutional TUBB Variant Associated With Familial Malformations of Cortical Development

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Most pathogenic tubulin variants arise de novo in sporadic patients, causing severe brain malformations and significant neurodevelopmental impairment. The resulting reproductive disadvantage typically prevents these mutations from being transmitted to offspring.

Impact of Chamber Dilatation on the Prognostic Value of Left Ventricular Geometry in Hypertension

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2017
BackgroundThe different geometric patterns of the left ventricle may or may not coexist with chamber dilatation. The prognostic impact of such a combination is unclear.

A Statistical Model for Risk Stratification on the Basis of Left Ventricular Ejection Fraction and Heart-Rate Turbulence [PDF]

, 2000
The MPIP data set was used to obtain a model for mortality risk stratification of acute myocardial infarction patients. The predictors heart rate turbulence (HRT) and left-ventricular ejection fraction (LVEF) were employed. HRT was a categorical variable
