Advanced Healthcare Materials, EarlyView.Microfluidic coaxial extrusion generates size‐controlled 3D lymphatic tubes from primary human dermal lymphatic endothelial cells in a defined four‐component matrix. These engineered vessels self‐organize into stable lymphatic endothelium, maintain selective macromolecular permeability for 30 days, and enable direct comparison with blood endothelial ...

Critical and umbilical points of a non-Gaussian random field
Physical Review E, 2013 Random fields in nature often have, to a good approximation, Gaussian characteristics. For such fields, the number of maxima and minima are the same. Furthermore, the relative densities of umbilical points, topological defects which can be classified into three types, have certain fixed values.

Timelike hypersurfaces in de Sitter space and Legendrian singularities [PDF]
, 2005 We construct a basic framework for the study of extrinsic differential geometry on timelike hypersurfaces from the view point of the theory of Legendrian singularities.

Pairs of geometric foliations of regular and singular surfaces [PDF]
, 2010 We examine some generic features of surfaces in the Euclidean 3-space $\mathbb{R}^3$ related to the Gauss map on the surface. We consider these features on smooth surfaces and on singular surfaces with a cross-cap singularity.

Natural Biomaterials for Osteochondral Repair: From Source to Strategy
Advanced Healthcare Materials, EarlyView.Biological origin‐guided overview of natural biomaterials and therapeutic strategies for osteochondral tissue engineering. The circular diagram categorizes representative materials and strategies into plant/algae‐derived, microbial‐derived, animal‐derived, and human‐derived sources, centered on an osteochondral defect repair model.

Umbilic points and Real hyperquadrics
, 1999 We show a refined version of the existence and uniqueness theorem to Chern-Moser normal form. The class of nondegenerate real hypersurfaces in normal form has a natural group action. Umbilic point is defined via normal form. Nondegenerate analytic real hypersurfaces are locally biholomorphic to a real hyperquadric whenever every point is umbilic in ...

Topological events on wave dislocation lines: birth and death of small loops, and reconnection
, 2007 In three-dimensional space, a wave dislocation, that is, a quantized (optical) vortex or phase singularity, is a line zero of a complex scalar wavefunction.

Nonstrictly Hyperbolic Conservation Laws
, 1991 Global existence of a 2 × 2 system of nonstrictly hyperbolic conservation laws is established for data in L∞. This system is a particular case in a canonical class of conservation laws with an isolated umbilic point (a point in the state space where ...
