On the onset of synchronization of Kuramoto oscillators in scale-free networks [PDF]

open access: yes, 2019
Despite the great attention devoted to the study of phase oscillators on complex networks in the last two decades, it remains unclear whether scale-free networks exhibit a nonzero critical coupling strength for the onset of synchronization in the ...

Towards the conversion of carbohydrate biomass feedstocks to biofuels via hydroxylmethylfurfural [PDF]

open access: yes, 2010
This review appraises the chemical conversion processes recently reported for the production of hydroxylmethylfurfural (HMF), a key biorefining intermediate, from carbohydrate biomass feedstocks. Catalytic sites or groups required for the efficient and

Biocatalytic Reduction of HMF to 2,5‐Bis(hydroxymethyl)furan by HMF‐Tolerant Whole Cells [PDF]

open access: yesChemSusChem, 2016
AbstractCatalytic upgrading of 5‐hydroxymethylfurfural (HMF), an important biobased platform chemical for high‐value products, is currently of great interest. In this work, a new highly HMFtolerant yeast strain—Meyerozyma guilliermondii SC1103 was isolated, and biocatalytic reduction of HMF to 2,5‐bis(hydroxymethyl)furan (BHMF) using its resting cells ...

Evaluation of Shelf Life and Heat Treatment of Tomato Products

open access: yesCzech Journal of Food Sciences, 2009
Model storage experiments of pasteurised tomato puree and ketchup were carried out. The sets of samples were boiled at 100°C, during the heating the changes of selected markers were followed and correlated with the sensory evaluation, the markers were ...

Impact of microwave heating on hydroxymethylfurfural content in Czech honeys

open access: yesCzech Journal of Food Sciences, 2011
As far as honey is concerned, microwave oven heating finds its use especially for crystallised honey reliquefying. We focused on monitoring the changes in hydroxymethylfurfural content which is an indicator of heat damage done to honey, among others ...

A Twenty Year Decline in Solar Photospheric Magnetic Fields: Inner-Heliospheric Signatures and Possible Implications?

open access: yes, 2015
We report observations of a steady 20 year decline of solar photospheric fields at latitudes $\geq$45${^{o}}$ starting from $\sim$1995. This prolonged and continuing decline, combined with the fact that Cycle 24 is already past its peak, implies that ...

Nonlinear Stability Criteria for the HMF Model [PDF]

open access: yesArchive for Rational Mechanics and Analysis, 2017
We study the nonlinear stability of a large class of inhomogeneous steady state solutions to the Hamiltonian Mean Field (HMF) model. Under a simple criterion, we prove the nonlinear stability of steady states which are decreasing functions of the microscopic energy.
