Conformation-controlled networking of H-bonded assemblies on surfaces [PDF]
, 2009 A temperature-induced phase transition of a 2D H-bonded assembly, enabling quadruple H-bonding interactions, from a hexagonal porous network into a close-packed rhombic arrangement has been observed on Ag(111) by STM imaging.

Area estimates and rigidity of capillary H-surfaces in three-manifolds with boundary [PDF]
Mathematische Zeitschrift, 2017 We discovered we needed to add a hypothesis in Theorem 5.1 {that Sigma separates M) and thus the theorem and its proof has been ...

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 ...

Geometric computation theory for morphological filtering on freeform surfaces [PDF]
, 2013 Surfaces govern functional behaviours of geometrical products, especially high precision and high added-value products. Compared to the mean-line based filters, morphological filters, evolved from the traditional E-system, are relevant to functional ...

The topology of large H-surfaces bounded by a convex curve [PDF]
Annales Scientifiques de l’École Normale Supérieure, 2000 The author studies embedded compact surfaces \(M\) of constant non-zero mean curvature \(H\) in hyperbolic space \(\mathbb H^3\) assuming that \(M\) is contained in the horoball bounded by a fix horosphere of \(\mathbb H^3\) and that the boundary of \(M\) is a strictly convex Jordan curve \(\Gamma\) in the horosphere.

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 ...

Investigation on hydrogenation performance of Mg17Al12 by adding Y
Scientific ReportsThe mechanism of Y on H/H2 adsorption performance of Mg17Al12 were studied by the density functional theory. We obtained that for the Y-adsorbed systems, Y tended to occupy on the bridge site between adjacent Mg atoms.

Multiple solutions of compact $H$-surfaces in Euclidean space
Topological Methods in Nonlinear Analysis, 2003 The paper deals with a procedure of finding of the multiple solutions with different energy for some multiply connected domains. Some minimax methods and topological arguments are used for the existence of such solutions.
