VISUALIZATION OF LINES OF CURVATURE ON QUADRATIC SURFACES [PDF]
Facta Universitatis, Series: Mathematics and Informatics, 2017 In this paper, we give a complete survey of the lines of curvature onquadratic surfaces, and, more generally, on tangent surfaces, generalcylinders and cones. We also apply our own software to the graphical representation of all the results we present.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

FEBS Letters, EarlyView.Septin 9 polybasic domains couple phosphoinositide‐rich membrane binding to centrosome positioning, Golgi organization, and microtubule acetylation to control epithelial polarity. Their loss disrupts this axis, causing centrosome mispositioning, Golgi fragmentation, reduced microtubule acetylation, and polarity inversion via upregulation of the ...

Curvature-Tilt Theories of Lipid Membranes
, 2019 On mesoscopic scales lipid membranes are well described by continuum theories whose main ingredients are the curvature of a membrane’s reference surface and the tilt of its lipid constituents. In particular, Hamm and Kozlov [Eur. Phys. J. E 3, 323 (2000)]

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Sweeping surfaces according to quasi curve and quasi focal curve in Euclidean 3-space
Open MathematicsIn this paper, sweeping surfaces generated by quasi curves and quasi focal curves are introduced using a quasi frame in the Euclidean 3-space. First, the singular points, the Gaussian and mean curvatures of sweeping surfaces with a quasi curve are ...

FEBS Letters, EarlyView.We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

The relation between parameter curves and lines of curvature on canal surfaces
Kuwait Journal of Science, 2017 A canal surface is the envelope of a moving sphere with varying radius, defined by the trajectory C(t) (spine curve) of its center and a radius function r(t).

EFFECT OF ASYMMETRY ON RADII OF CURVATURE FOR SPUR GEARS WITH NONSYMMETRICAL TEETH [PDF]
Scientific Journal of Silesian University of Technology. Series Transport, 2014 This article discusses the involute gears with asymmetric teeth wheels and resolves radii of curvature for different parameter values of gearing. The article deals with the reduced radii of curvature in the pitch point and the extreme points of the ...
