Probabilistic Dominant Frequency Estimation in AF From ECGI.

open access: yes, 2023
Non-invasive estimation of high frequency activation regions in atrial fibrillation (AF) may have an important role in patient stratification and ablation guidance. This work presents a methodology to robustly estimate DF maps in ECGI, where the uncertainty associated to the estimates is modelled making use of a set of ECGI solutions from a range of ...

Seismic Vulnerability Index Study of Lasem Fault Zone Using HVSR Method Based on Microtremor Data

open access: yesBerkala Sainstek
The Lasem Fault Zone is one of the tectonically active areas in Central Java that has the potential to trigger damaging earthquakes. To identify seismic vulnerability in this area, a microzonation approach based on soil dynamic parameters is required to ...

Vortex identification and evolution of a jet in cross flow based on Rortex

open access: yesEngineering Applications of Computational Fluid Mechanics, 2020
Jet in cross flow is an important issue in engineering practice, for example, it is used to improve turbine efficiency in film cooling. In this study, the large eddy simulation and the spectrum analysis are employed to analyze the vortices in a jet in ...

Surrogate Data Method Requires End-Matched Segmentation of Electroencephalographic Signals to Estimate Non-linearity

open access: yesFrontiers in Physiology, 2018
The aim of the study is to clarify the impact of the strong cyclic signal component on the results of surrogate data method in the case of resting electroencephalographic (EEG) signals. In addition, the impact of segment length is analyzed. Different non-

The LDP at 50: The Rise, Power Resources, and Perspectives of Japan’s Dominant Party [PDF]

open access: yes
Japan’s ruling party is a prime example of a dominant party. While dominant parties in other democracies around the world have lost their grip on power or have even disappeared altogether, the LDP is still going strong.

Frequency-Dependent Selection for the Dominance of Rare Polymorphic Genes [PDF]

open access: yesEvolution, 1964
There are a number of examples of genetic polymorphism in which a balance seems to be maintained, at least in part, by frequency-dependent selection. The selective value of each gentoype is then negatively related to its frequency. Mimetic polymorphisms are perhaps the best known examples (Sheppard, 1958), but there is evidence that frequency-dependent

Frequency-comb-induced radiation pressure force in dense atomic clouds

open access: yes, 2021
We investigate the frequency comb induced radiation pressure force acting on a cloud of cold $^{87}$Rb atoms. Reduction and spectral broadening of the frequency comb force are observed as the cloud's optical thickness is increased.
