Spatial structure alters the site frequency spectrum produced by hitchhiking.
Min J, Gupta M, Desai MM, Weissman DB. Min J, et al. Genetics. 2022 Nov 1;222(3):iyac139. doi: 10.1093/genetics/iyac139. Genetics. 2022. PMID: 36094352 Free PMC article.
For such populations, sweeps spread as Fisher waves, rather than logistically. We find that this leaves a characteristic 3-part site frequency spectrum at loci very close to the swept locus. Very low frequencies are dominated by recent mutations that occurred …

The spatial frequency spectrum of fearful faces modulates early and mid-latency ERPs but not the N170.
Bruchmann M, Schindler S, Straube T. Bruchmann M, et al. Psychophysiology. 2020 Sep;57(9):e13597. doi: 10.1111/psyp.13597. Epub 2020 May 10. Psychophysiology. 2020. PMID: 32390215
Behavioral advantages have recently been associated with the spatial frequency spectrum of fearful faces, better fitting the human contrast sensitivity function than the spectrum of neutral faces. ...We found an enlarged N170 to fearful versus neutral …

Spatial frequency spectrum of the x-ray scatter distribution in CBCT projections.
Bootsma GJ, Verhaegen F, Jaffray DA. Bootsma GJ, et al. Med Phys. 2013 Nov;40(11):111901. doi: 10.1118/1.4822484. Med Phys. 2013. PMID: 24320434
Estimates of the scatter distribution are used to correct and reconstruct simulated projections. RESULTS: The spatial and angular frequencies are contained within a maximum frequency of 0.1 cm(-1) and 7/(2pi) rad(-1) for the imaging scenarios examined, with t …

Malaria Molecular Epidemiology: An Evolutionary Genetics Perspective.
Escalante AA, Pacheco MA. Escalante AA, et al. Microbiol Spectr. 2019 Jul;7(4):10.1128/microbiolspec.AME-0010-2019. doi: 10.1128/microbiolspec.AME-0010-2019. Microbiol Spectr. 2019. PMID: 31400095 Free PMC article. Review.
Such complexities have propelled the study of parasite genetic diversity patterns in the context of epidemiologic investigations. Importantly, molecular studies indicate that the time and spatial distribution of malaria cases reflect epidemiologic processes that cannot be …

Characterization of the spatial-frequency spectrum in the perception of shape from texture.
Sakai K, Finkel LH. Sakai K, et al. J Opt Soc Am A Opt Image Sci Vis. 1995 Jun;12(6):1208-24. doi: 10.1364/josaa.12.001208. J Opt Soc Am A Opt Image Sci Vis. 1995. PMID: 7769507
A number of computational models have been proposed in which compression is measured by detection of changes in the spatial-frequency spectrum [Comput. Graphics Image Process. 5, (1976)]. ...Changes in fp are strongly correlated with the degree of surface cur …

Spatial frequency equalization does not prevent spatial-numerical associations.
Adriano A, Rinaldi L, Girelli L. Adriano A, et al. Psychon Bull Rev. 2022 Aug;29(4):1492-1502. doi: 10.3758/s13423-022-02060-w. Epub 2022 Feb 7. Psychon Bull Rev. 2022. PMID: 35132580 Free PMC article.
There is an intense debate surrounding the origin of spatial-numerical associations (SNAs), according to which small numbers are mapped onto the left side of the space and large numbers onto the right. Despite evidence suggesting that SNAs would emerge as an innate predisp …

Compressive frequency-difference direction-of-arrival estimation.
Lee JH, Park Y, Gerstoft P. Lee JH, et al. J Acoust Soc Am. 2023 Jul 1;154(1):141-151. doi: 10.1121/10.0020053. J Acoust Soc Am. 2023. PMID: 37432051
Am. 132, 3018-3029] offers an alternative approach to avoid such spatial aliasing by using multifrequency signals and processing them at a lower frequency, the difference-frequency. ...Similar to compressive beamforming, the improvement (compressive freque …

An action spectrum for spatial-frequency adaptation.
Swift DJ, Smith RA. Swift DJ, et al. Vision Res. 1982;22(2):235-46. doi: 10.1016/0042-6989(82)90123-7. Vision Res. 1982. PMID: 7101759
The mechanism of spatial-frequency adaptation, and channel-bandwidth estimates derived from adaptation, were examined in a series of three experiments. The first two experiments measured adaptation as a function of both the frequency and modulation of the ada …

Spatial summation of broadband contrast.
Richard B, Hansen BC, Johnson AP, Shafto P. Richard B, et al. J Vis. 2019 May 1;19(5):16. doi: 10.1167/19.5.16. J Vis. 2019. PMID: 31100132 Free article.
Spatial summation of luminance contrast signals has historically been psychophysically measured with stimuli isolated in spatial frequency (i.e., narrowband). Here, we revisit the study of spatial summation with noise patterns that contain the naturali …
