Gravitational multi-NUT solitons, Komar masses and charges [PDF]

, 2008
Generalising expressions given by Komar, we give precise definitions of gravitational mass and solitonic NUT charge and we apply these to the description of a class of Minkowski-signature multi-Taub-NUT solutions without rod singularities.

Assembly of Cell‐Seeded 3D Printed Hydrogel Modules with Perfusable Channel Networks

Advanced Functional Materials, EarlyView.
Macroscale assembly was utilized to prepare perfusable tissue constructs from individually 3D printed hydrogel modules with embedded branched channel networks and port arrays for cell seeding. Novel multi‐material bioreactors were fabricated to facilitate the gluing of individual modules and the perfusion culture of assembled modular constructs seeded ...

Assessment of Three Provenances of Juglans neotropica Diels to Identify Optimal Seed Sources in the Northern Ecuadorian Andes

International Journal of Plant Biology
Identifying optimal seed sources is critical for the propagation and restoration of Juglans neotropica Diels in the northern Ecuadorian Andes, where populations are declining due to habitat loss and overexploitation. This study evaluated the seed quality

Massive Nonlinear Sigma Models and BPS Domain Walls in Harmonic Superspace

, 2004
Four-dimensional massive N=2 nonlinear sigma models and BPS wall solutions are studied in the off-shell harmonic superspace approach in which N=2 supersymmetry is manifest.

Pattern Formation in Non‐Equilibrium Architected Materials

Advanced Materials Technologies, EarlyView.
This article demonstrates an artificial mechanical system ‐ a robotic metamaterial ‐ as an accessible and versatile platform within which to explore and prescribe the reaction‐diffusion driven pattern formation hitherto associated with comparatively less accessible and versatile non‐equilibrium biological and chemical systems.

Effects of dietary management for medium-chain acyl-CoA dehydrogenase deficiency (MCADD) on eating behaviour in childhood, adolescence and young adulthood

BMC Nutrition
Background Medium-chain acyl-CoA dehydrogenase deficiency (MCADD) is an autosomal recessive disorder of ß-oxidation. A loss of enzyme function results in impaired breakdown of medium-chain fatty acids.

A valid method for determining the water content of the Brazil nut (Bertholletia excelsa)

Bioscience Journal, 2016
For proper handling of a product knowledge regarding its water content is essential. To provide fast, inexpensive and reliable results, the direct evaporation method of water in oil bath (EDABO) has been proven to be a viable alternative, at all stages ...

The Action of Instantons with Nut Charge

, 1998
We examine the effect of a non-trivial nut charge on the action of non-compact four-dimensional instantons with a U(1) isometry. If the instanton action is calculated by dimensionally reducing along the isometry, then the nut charge is found to make an ...
