Topological Equivalence and Curvature Convergence: Bezier Surface Approximation [PDF]

open access: yesarXiv, 2013
A set of control points can determine a Bezier surface and a triangulated surface simultaneously. We prove that the triangulated surface becomes homeomorphic and ambient isotopic to the Bezier surface via subdivision. We also show that the total Gaussian curvature of the triangulated surface converges to the total Gaussian curvature of the Bezier ...

Quantum oscillation studies of the Fermi surface of iron-pnictide superconductors

open access: yes, 2011
This paper reviews quantum oscillation studies of iron-pnictide superconductors and related materials. These measurements give unique information regarding the full three dimensional topology of the Fermi surfaces and the renormalisation of the quasi ...

On-surface synthesis of a nitrogen-embedded buckybowl with inverse Stone–Thrower–Wales topology

open access: yesNature Communications, 2018
Curved π-conjugated polycyclic aromatic hydrocarbons, buckybowls, constitute an important class of materials with wide applications in materials science. Heteroatom doping of buckybowls is a viable route to tune their intrinsic physicochemical properties.

Benchtop Fabrication and Integration of Laser‐Induced Graphene Strain Gauges and Stimulation Electrodes in Muscle on a Chip Devices

open access: yesAdvanced Functional Materials, Volume 35, Issue 13, March 25, 2025.
Laser‐induced graphene (LIG) is patterned on polyimide films and then transferred into thin layers of polydimethylsiloxane (PDMS), resulting in flexible and stretchable conductive LIG‐PDMS constructs that are stable under repeated deformation and incubation in buffer. LIG‐PDMS is integrated into Muscle on a Chip devices and deployed as miniature strain

An elementary proof of the string topology structure of compact oriented surfaces [PDF]

open access: yesarXiv, 2011
We give a new proof of the string topology structure of a compact oriented surface of genus g greater than or equal to 2, using elementary algebraic topology. This reproves the result of Vaintrob.

Thermally Induced Gelling Systems Based on Patchy Polymeric Micelles

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
A novel strategy to design thermally induced gelling systems with tunable material properties is reported. Polymeric mixed‐shell micelles displaying multiple thermosensitive patchy domains formed hydrogels by assembling into well‐entangled worm‐like network structures upon heating to body temperature. The patchy micelle design significantly affects the

Symbolic Block Decomposition In Hexahedral Mesh Generation

open access: yesComputer Science, 2005
Hexahedral mesh generation for three-dimensional solid objects is often done in stages. Usually an object is first subdivided into simple-shaped subregions, which then are filled withhexahedral finite elements. This article presents an automatic subdividing

Topological complexity of collision-free multi-tasking motion planning on orientable surfaces [PDF]

open access: yesarXiv, 2016
We compute the higher topological complexity of ordered configuration spaces of orientable surfaces, thus extending Cohen-Farber's description of the ordinary topological complexity of those spaces.
