Amplitude Response Curves of Frequency-Locked Rotations
This letter studies frequency-locked rotations in a phaselocked loop (PLL) circuit as FM demodulator. A rotation represents a desynchronized steady state in the PLL circuit and is regarded as another type of self-excited oscillations with natural rotation frequencies. The rotation frequency can be locked at driving frequencies of modulation signals. This letter shows response curves for harmoni...
متن کاملComparative analysis of spectro-temporal receptive fields, reverse correlation functions, and frequency tuning curves of auditory-nerve fibers.
The tuning properties of single auditory-nerve fibers (ANFs) are characterized with spectro-temporal receptive fields (STRFs), reverse correlation functions (revcors), and frequency tuning curves (FTCs). Measures of tuning and latency from the STRFs and revcors are largely comparable to the traditional measures of tuning from FTCs and measures of latency from peristimulus time histograms (PSTHs...
متن کاملAssessment of uncertainty for coal quality-tonnage curves through minimum spatial cross-correlation simulation
Coal quality-tonnage curves are helpful tools in optimum mine planning and can be estimated using geostatistical simulation methods. In the presence of spatially cross-correlated variables, traditional co-simulation methods are impractical and time consuming. This paper investigates a factor simulation approach based on minimization of spatial cross-correlations with the objective of modeling s...
متن کاملBOLD fMRI Correlation Reflects Frequency-Specific Neuronal Correlation
The brain-wide correlation of hemodynamic signals as measured with BOLD fMRI is widely studied as a proxy for integrative brain processes. However, the relationship between hemodynamic correlation structure and neuronal correlation structure remains elusive. We investigated this relation using BOLD fMRI and spatially co-registered, source-localized MEG in resting humans. We found that across th...
متن کاملFrequency of two VKORC1 gene variants and its correlation with warfarin maintenance dose
Warfarin is a commonly-prescribed anticoagulant used to treat and prevent thromboembolic events. The requirement for varying doses of warfarin depends on genetic and environmental components. In this study, the frequency of two single-nucleotide polymorphic variants of the vitamin K epoxide reductase complex subunit 1 (VKORC1) gene (1173 C>T (rs9934438) and 3730 G>A (rs7294)) and its correlatio...
