Transcriptome and DNA methylation profiling during the NSN to SN transition in mouse oocytes
Published 2025-01-01“…The classifier was successfully tested in multiple published datasets of mouse models with a known skew in NSN: SN ratios. Analysis of the scBS-seq data showed increased DNA methylation in SN compared to NSN oocytes, which was most pronounced in regions with intermediate levels of methylation. …”

Vortex-Induced Vibration Suppression of a Circular Cylinder with Vortex Generators
Published 2016-01-01“…Vortex generator control can make the boundary layer profile fuller and hence more resistant to separation. The selections of skew angles and the angular position have a significant influence on the vortex generator control effect. …”

Depth-Based Classification for Distributions with Nonconvex Support
Published 2013-01-01“…The data depth approach is used instead of the linear discriminant analysis mostly to avoid the parametric assumptions and to get better classifier for data whose distribution is not elliptically symmetric, for example, skewed data. In our paper, we suggest to use weighted version of halfspace depth rather than the halfspace depth itself in order to obtain lower misclassification rate in the case of “nonconvex” distributions. …”

Neo-Characterization in the Neo-Victorian Novel
Published 2015-12-01“…Hopefully, this cursory, panoramic overview might shed some light on the centrality of character (character-building, -skewing, -bending, -sapping and so forth) in operating a shift from Victorian characterization to what may be designated as neo-Victorian neo-characterization; i.e. a renewed return to a familiar novelistic cast. …”

Least-Norm of the General Solution to Some System of Quaternion Matrix Equations and Its Determinantal Representations
Published 2019-01-01“…We constitute some necessary and sufficient conditions for the system A1X1=C1, X1B1=C2, A2X2=C3, X2B2=C4, A3X1B3+A4X2B4=Cc, to have a solution over the quaternion skew field in this paper. A novel expression of general solution to this system is also established when it has a solution. …”

All-angle unidirectional flat-band acoustic metasurfaces
Published 2025-01-01“…Here, we report an acoustic flat-band metasurface, allowing not only unidirectional canalization at all in-plane angles but also robust tunability in band alignment. The twist, tilt, and skew angles of the bilayer metasurface can be flexibly controlled to break both in-plane and out-of-plane spatial symmetries. …”
