Developments in noncommutative differential geometry [PDF]
, 2002 One of the great outstanding problems of theoretical physics is the quantisation of gravity, and an associated description of quantum spacetime. It is often argued that, at short distances, the manifold structure of spacetime breaks down and is replaced ...

Microfabricated Anisotropic Myobundles for the Scalable Production of Cardiac Tissue Grafts
Advanced Functional Materials, EarlyView.Controlling the anisotropy of cardiac tissue remains an outstanding challenge in the field of cardiac tissue engineering. Here, we introduce an approach to generate anisotropic cardiac myobundles using cell‐adhesive, synthetic, electrospun fibers and stem cell‐derived cardiac fibroblasts.

Quantum duality principle and quantum symmetric pairs
Forum of Mathematics, SigmaThe quantum duality principle (QDP) by Drinfeld predicts a connection between the quantized universal enveloping algebras and the quantized coordinate algebras, where the underlying classical objects are related by the duality in Poisson geometry.

ON POISSON GEOMETRY AND SUPERSYMMETRIC SIGMA MODELS [PDF]
Modern Physics Letters A, 2012 By using the Poisson geometry, we develop a manifestly invariant and calculation-friendly formalism for handling UOSp(2|1)-supersymmetric field theories. In particular, the super-Langrangians are written solely in terms of superfields, Poisson brackets and the moment map generating the UOSp(2|1) action.

Normal forms in Poisson geometry
, 2013 The structure of Poisson manifolds is highly nontrivial even locally. The first important result in this direction is Conn's linearization theorem around fixed points. One of the main results of this thesis (Theorem 2) is a normal form theorem in Poisson

Conformal Metallosaccharide Hybrid Films for Protecting Wood Surfaces From Environmental Damage
Advanced Functional Materials, EarlyView.Ti‐ribose hybrid films fabricated by molecular layer deposition form a conformal and uniform coating on wood surfaces, which provides water repellence, dimensional stability, and resistance to acidic and alkaline environments, while preserving the natural appearance.

A New Stochastic Geometry Model of Coexistence of Wireless Body Sensor Networks
MATEC Web of Conferences, 2017 Stochastic geometry, in particular Poission point process theory, has been widely used in the last decade to provide models and methods to analyze wireless networks.

Structure‐Guided Dynamical Mechanics in Bioinspired Double Twisted Laminated Thin Films
Advanced Functional Materials, EarlyView.This work explores a dynamic mechanistic study of crack propagation and puncture testing via real‐time monitoring of crack initiation, propagation, and termination through nature‐inspired single and double twisted architectures fabricated from cellulose nanocrystals.

Holonomic Poisson geometry of Hilbert schemes
We undertake a detailed study of the geometry of Bottacin's Poisson structures on Hilbert schemes of points in Poisson surfaces, i.e. smooth complex surfaces equipped with an effective anticanonical divisor. We focus on three themes that, while logically
