Projective-umbilic points of circular real hypersurfaces in $\mathbb {C}^2$
Proceedings of the American Mathematical Society, 2020 We show that the boundary of any bounded strongly pseudoconvex complete circular domain in $\mathbb C^2$ must contain points that are exceptionally tangent to a projective image of the unit sphere.

An algorithm for the optimisation of n-forms using symmetric multilinear forms
, 1987 This paper describes an algorithm for locating stationary points of n-forms. Use is made of the associated n-linear form, the stationary points of which are seen to coincide with those of the n-form.

A Pressure Microsensor Made of Parylene‐C for Use as Medical Implant
Advanced Materials Technologies, EarlyView.A monolithic parylene‐C pressure sensor with gold strain gauges provides 6.2 μV$\mu{\rm V}$·mmHg$\cdot{\rm mmHg}$−1$^{-1}$ sensitivity. The morphology of a sputtered thin film strain sensor is granular/columnar, which results in a high gauge factor of 7.5. Thermal bonding and parylene‐C coating create a hermetic cavity.

Additive Manufacturing of Patient‐Specific Intracranial Aneurysm Cell Culture Models
Advanced Materials Technologies, EarlyView.Patient‐specific intracranial aneurysm models were fabricated using chocolate moulding, 3D printed water‐soluble cores, and direct resin 3D printing. Moulding PDMS around sacrificial cores made of chocolate or 3D printed water‐soluble resin yielded accurate, expandable, and endothelializable models that outperformed resin‐based approaches.

Advanced Science, EarlyView.Perivascular matrix densification promotes the emergence of aberrant endothelial tip cells (ATECs) that invade and persist within fibrotic microenvironments. Using in vivo lineage tracing and a human microvessel model, this study shows that fibrous matrix cues destabilize VE‐cadherin–mediated junctions to gate TGF‐β signaling, inducing a pro ...

The behavior of the principal distributions around an isolated umbilical point
Journal of the Mathematical Society of Japan, 2001 Let \(G_f\) be the graph of a homogeneous polynomial \(f\) in two variables of degree \(k\geq 3\) such that the origin \(o\) of \(R^3\) is an isolated umbilical point. If \(\Theta_0\) is a real number at which \({df\over d\Theta} (\cos\Theta,\sin\Theta)\) vanishes, the straight line \(L(\Theta_0): =\{(x,y)\in R^2\); \(x\sin\Theta_0 -y\cos\Theta_0 =0\}\)

New solution to Airy's equation for modeling beams near turning points
, 2023 Here I present a summarised description of the general behavior of waves near turning points. I show that when asymptotic matching to a prescribed incident wavefield is performed, the solution changes from being the Airy function to being more generally ...

Advanced Science, EarlyView.By integrating data from in vitro, ex vivo, and in vivo models, our research identifies the MARV glycoprotein as a remarkable hemorrhagic factor, filling a major gap in this important field. It also provides practical experimental tools for the basic research on viral pathogenesis and applied research aimed at antiviral intervention for hemorrhagic ...

Advanced Science, EarlyView.Nitrosyl heme emerges as an extracellular nitrodilator that dilates arteries without crossing the cell membrane. Instead, heme‐NO mobilizes NO moieties from a preformed intracellular NO store within vascular smooth muscle, providing both functional and chemical evidence for the NANOS model, revealing a previously unrecognized mechanism of arterial ...
