Frequency spectrum recurrence analysis. [PDF]
Sci Rep, 2020 AbstractIn this paper, we present the new frequency spectrum recurrence analysis technique by means of electro-encephalon signals (EES) analyses. The technique is suitable for time series analysis with noise and disturbances. EES were collected, and alpha waves of the occipital region were analysed by comparing the signals from participants in two ...

Revisiting the Transferability of Few-Shot Image Classification: A Frequency Spectrum Perspective [PDF]
EntropyFew-shot learning, especially few-shot image classification (FSIC), endeavors to recognize new categories using only a handful of labeled images by transferring knowledge from a model trained on base categories.

The Site Frequency Spectrum for General Coalescents. [PDF]
Genetics, 2016 Abstract General genealogical processes such as Λ- and Ξ-coalescents, which respectively model multiple and simultaneous mergers, have important applications in studying marine species, strong positive selection, recurrent selective sweeps, strong bottlenecks, large sample sizes, and so on.

Substrate Integrated Waveguide Quasi-Elliptic Filter with Arbitrary Termination Impedances [PDF]
Journal of Electromagnetic Engineering and Science, 2022 This paper presents a quasi-elliptic filter (QEF) with arbitrary termination impedances (ATI). The proposed QEF is designed by adding cross-coupling between the first and last resonators of an ATI bandpass filter (BPF) with the Chebyshev response.

Comparison of focusing of short pulses in the Debye approximation [PDF]
Компьютерная оптика, 2018 We have examined different types of pulses and features of their frequency spectra. Calculations have shown that a significant distinction between the pulses only takes place at a very short pulse duration (shorter than the oscillation period).

The observed power spectrum & frequency-angular power spectrum
Physical Review D, 2023 The two-point summary statistics is one of the most commonly used tools in the study of cosmological structure. Starting from the theoretical power spectrum defined in the 3D volume and obtained via the process of ensemble averaging, we establish the construction of the observed 3D power spectrum, folding the unequal-time information around the average
