2-(5-Bromo-2-methylphenyl)propan-2-ol

Acta Crystallographica Section E, 2010
The title compound, C10H13BrO, crystallizes with four independent molecules of similar geometry in the asymmetric unit. The crystal packing is stabilized by intermolecular O—H...O hydrogen bonds, which link the molecules into tetramers.

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

bioRxiv, 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

, 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

D-branes in Kazama-Suzuki Models [PDF]

, 1997
We investigate boundary states of D-branes wrapped around supersymmetric cycles in Kazama--Suzuki models. We show that the geometry of the D-branes corresponds to a generalisation of calibrated geometry.

Stochastic Thermodynamic Interpretation of Information Geometry. [PDF]

Physical 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 ...

Homotopy K3's with several symplectic structures

, 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

Plant 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.
