Electrophysiological Consequences of Cardiac Fibrosis

open access: yesCells, 2021
For both the atria and ventricles, fibrosis is generally recognized as one of the key determinants of conduction disturbances. By definition, fibrosis refers to an increased amount of fibrous tissue. However, fibrosis is not a singular entity.

An Uncertainty Modeling Framework for Intracardiac Electrogram Analysis

open access: yesBioengineering, 2020
Intracardiac electrograms (EGMs) are electrical signals measured within the chambers of the heart, which can be used to locate abnormal cardiac tissue and guide catheter ablations to treat cardiac arrhythmias.

Electrical conduction in nanogranular cluster-assembled metallic films

open access: yesAdvances in Physics: X, 2021
A film fabricated by the assembling of nanoparticles that retain, at least partially, their individuality is expected to show substantially different structural and functional properties compared to the case where atoms or molecules are used as building ...

Luttinger-liquid-like transport in long InSb nanowires

open access: yes, 1999
Long nanowires of degenerate semiconductor InSb in asbestos matrix (wire diameter is around 50 \AA, length 0.1 - 1 mm) were prepared. Electrical conduction of these nanowires is studied over a temperature range 1.5 - 350 K.

Conduction of Electricity in Solids [PDF]

open access: yesNature, 1937
THE modern theory of the conduction of electricity in solids has already been applied to a large number of special problems; all that can be attempted here is a broad sketch of the fundamental ideas of the theory, together with an account of one or two of the most recent develop ments.

Violation of Wiedemann-Franz law at the Kondo breakdown quantum critical point

open access: yes, 2008
We study both the electrical and thermal transport near the heavy-fermion quantum critical point (QCP), identified with the breakdown of the Kondo effect as an orbital selective Mott transition.

Thermally Stimulated Currents in Nanocrystalline Titania

open access: yesNanomaterials, 2018
A thorough study on the distribution of defect-related active energy levels has been performed on nanocrystalline TiO2. Films have been deposited on thick-alumina printed circuit boards equipped with electrical contacts, heater and temperature sensors ...
