Shape matters: the relationship between cell geometry and diversity in phytoplankton

open access: yesbioRxiv, 2020
Organisms’ size and shape profoundly influence their ecophysiological performance and evolutionary fitness, suggesting a link between morphology and diversity.

Examples of noncommutative manifolds: complex tori and spherical manifolds

open access: yes, 2007
We survey some aspects of the theory of noncommutative manifolds focusing on the noncommutative analogs of two-dimensional tori and low-dimensional spheres. We are particularly interested in those aspects of the theory that link the differential geometry

A link invariant from the symplectic geometry of nilpotent slices [PDF]

open access: green, 2004
We define an invariant of oriented links in S 3 using the symplectic geometry of certain spaces which arise naturally in Lie theory. More specifically, we present a knot as the closure of a braid, which in turn we view as a loop in configuration space ...

Stochastic Thermodynamic Interpretation of Information Geometry. [PDF]

open access: yesPhysical Review Letters, 2017
In recent years, the unified theory of information and thermodynamics has been intensively discussed in the context of stochastic thermodynamics. The unified theory reveals that information theory would be useful to understand nonstationary dynamics of ...

Complex surface singularities with integral homology sphere links [PDF]

open access: yes, 2005
While the topological types of {normal} surface singularities with homology sphere link have been classified, forming a rich class, until recently little was known about the possible analytic structures. We proved in [Geom. Topol.

The Link between Ag‐Paste Rheology and Screen‐Printed Solar Cell Metallization

open access: yesAdvanced Materials & Technologies, 2020
Today's photovoltaic production chain is moving into a material crisis as the use of silver for front‐side metallization of passivated emitter and rear contact solar cells remains a crucial requirement.

Homotopy K3's with several symplectic structures

open access: yes, 2001
In this note we prove that, for any integer n, there exist a smooth 4-manifold, homotopic to a K3 surface, defined by applying the link surgery method of Fintushel-Stern to a certain 2-component graph link, which admits n inequivalent symplectic ...

Measuring crops in 3D: using geometry for plant phenotyping

open access: yesPlant Methods, 2019
Using 3D sensing for plant phenotyping has risen within the last years. This review provides an overview on 3D traits for the demands of plant phenotyping considering different measuring techniques, derived traits and use-cases of biological applications.

Reeb orbits and the minimal discrepancy of an isolated singularity [PDF]

open access: yes, 2015
Let A be an affine variety inside a complex N dimensional vector space which has an isolated singularity at the origin. The intersection of A with a very small sphere turns out to be a contact manifold called the link of A.

Markov blankets, information geometry and stochastic thermodynamics

open access: yesPhilosophical Transactions of the Royal Society A, 2019
This paper considers the relationship between thermodynamics, information and inference. In particular, it explores the thermodynamic concomitants of belief updating, under a variational (free energy) principle for self-organization.
