Advanced Science, EarlyView.Dynamic decellularized hydrogels are prepared using bovine decellularized small intestine submucosa (SIS) norbornene (dSIS‐NB). Bovine dSIS contained significant amounts of disulfide‐rich fibrillin‐I, enabling ‘self‐clickable’ thiol‐norbornene gelation and spatiotemporal tuning of hydrogel physicochemical properties.

An umbilical point on a non-real-analytic surface
Hiroshima Mathematical Journal, 2003 The index of an isolated umbilical point on a surface in three-dimensional Euclidean space is studied. The main attention is paid to the following index conjecture: the index of an isolated umbilical point is not more than one. This conjecture is motivated by studying constant mean curvature surfaces whose isolated umbilical points are always of ...

Advanced Science, EarlyView.A dual‐network protein hydrogel substantially improves hemostasis and scar‐free healing.The adaptive network maintains intimate tissue contact while providing strong wet adhesion, tunable mechanics, and controlled degradation. Concurrent ROS scavenging and M2 polarization suppress fibrotic pathways, preventing scar formation.

Existence of Generalized Totally Umbilic 2-Spheres in Perturbed 3-Spheres
, 2017 It was recently shown by Souam and Toubiana [34] that the (nonconstantly curved) Berger spheres do not contain totally umbilic surfaces. Nevertheless, in this article we show, by perturbative arguments, that all analytic metrics sufficiently close to the

The asymptotic expansion of certain canonical integrals
, 1984 Integrals of the form I(λ) = ∝R2ƒ(x̄) exp{iλφ(x̄)} dx̄, common in diffraction theory, are usually evaluated asymptotically for large λ using the stationary phase technique. At caustic points the classical technique is not applicable.

Advanced Science, EarlyView.ABSTRACT Tumor immune escape is a major barrier to durable cancer immunotherapy, as advanced malignancies create a tumor microenvironment (TME) that preferentially exhausts and disables T cell responses. While most approved cell therapies are T cell‐based, this limitation motivates the exploration of an alternative effector cell platform.

Solid Ethanol as a Renewable, Low‐Toxicity, Electron‐Beam Direct Write, and Biomedical Material
Advanced Science, EarlyView.3D ice lithography (3DIL) enables the fabrication of intricate submicrometer objects using ethanol as a renewable starting material. This study combines process optimization, structural and material analysis, and biomedical applications, from cell culture scaffolds to the patterning of neurostimulation electrodes, demonstrating performance in both in ...
