To investigate the dynamic response characteristics of a bedding rock slope, the time, frequency, and time-frequency domains joint analysis methods were used by two-dimensional finite element method (FEM) dynamic analyses. The results show that bedding structural plane has different impacts on the ...

Here we propose a novel approach to solve this problem, based on joint time–frequency analysis in transform domain. Different from previous methods, we analyze the time–frequency characteristics about traffic matrix and build the time–frequency model describing it. Generally, traffic matrix can be...
In this work, we generate and use a total of six different wideband signals for joint time–frequency characterization of nonlinear time-invariant [N-shaped differential resistor (NDR)] and linear time-varying (thermistor) circuits. A data acquisition board is used for applying the signals...
Detection of fracture properties can be implemented using azimuth-dependent seismic inversion for optimal model parameters in time or frequency domain. Considering the respective potentials for sensitivities of inversion resolution and anti-noise perform
frequency of 120 Hz, aligned with the video timestamps (exactly four bins aligned with each frame). The dataset contains recordings for ten repeats, and we used the same video (Movie 1) that was used for the 2P recordings. For analysis of consistency across the visual cortical areas we...
We hypothesized that the frequency of antimicrobial-resistant organisms in PJIs has increased in recent years. Methods Setting, study design and patients An ambidirectional observational study was performed in 19 hospitals in Spain, within the framework of the Spanish Network for Research in Infectious...
Statistical analysis Descriptive analysis Data were summarized in frequency tables and figures (frequency for categorical variables, median and InterQuartile Range (IQR) for continuous variables), histograms, and boxplots. Non parametric tests (Wilcoxon and Kruskal–Wallis test) were computed to compare...
All methods perform approximately equally well, including naïve unintegrated analysis. The cell type ASW (cASW) assesses how separated cell types are; the average distance to another cell of the same cell type compared to the average distance to another cell of a different type. JOINTLY ranks...
