The fractional mean curvature flow
Web23 Mar 2024 · This positive curvature occurs at the base of the hypocotyl and is followed by the typical negative gravity-induced curvature. We investigated the role of auxin in both positive and negative hypocotyl curvature by examining the transcription of PIN1, PIN3, IAA5 and ARG1 in curving tissue. Web11 Jun 2024 · Our results show that the motion by (fractional) mean curvature flow can be approximated by fractional heat diffusion and by a diffusion by means of harmonic …

WebTHE FRACTIONAL MEAN CURVATURE FLOW 21 with respect to the local case is related to the fact that fractional minimal surfaces can stick at the boundary of (even smooth and … WebA denoising model is suggested hybridizing total variation and Laplacian mean-curvature; the fourth-order model and its numerical procedure introduce a number of parameters. As a preliminary step in the model development, a parameter study has been undertaken in order to discover solitary and interactive effects of the parameters on model accuracy.
WebPSVR was significantly correlated with hyperemic MPG ( R =0.52; P <0.05) and pFFR ( R =–0.50; P <0.05). The optimal cut-off value of pFFR as an indicator of significant hemodynamic stenosis (PSVR >2.5) was 0.85 (area under the curve 0.72; sensitivity 94%; specificity 50%, P <0.05). Conclusion: pFFR measured using a pressure wire is reliable ... WebThis paper is concerned with the study of a geometric flow whose law involves a singular integral operator.
