Heat-driven spin currents on large scales

Using a three-current model (i.e. heat, spin-up and spin-down electrons) the thermodynamics of irreversible processes predicts that a temperature gradient gives rise to a spin current on large scales, in particular under the conditions used to measure the ...

Experimental charge density of LiBD4 from maximum entropy method

Philippe Mauron

We report on maximum entropy method study of the experimental atomic and ionic charges of LiBD4 in its low-temperature orthorhombic phase. Synchrotron radiation x-ray powder diffraction data, neutron powder diffraction data, and density functional calculat ...

Direct comparison of phase-sensitive vibrational sum frequency generation with maximum entropy method: Case study of water

Sylvie Roke

We present a direct comparison of phase sensitive sum-frequency generation experiments with phase reconstruction obtained by the maximum entropy method. We show that both methods lead to the same complex spectrum. Furthermore, we discuss the strengths and ...

Hysteresis phenomena of a Macroscopic Fundamental Diagram in freeway networks

Nikolaos Geroliminis

Observations of traffic pairs of flow vs. density or occupancy for individual locations in freeways or arterials are usually scattered about an underlying curve. Recent observations from empirical data in arterial networks showed that in some cases by aggr ...

Correlations between Vibrational Entropy and Dynamics in Liquids

Matthieu Wyart

An approximate relation between the vibrational entropy and the mean square displacement of the particles is derived. Using observations of the short-time dynamics in liquids of various fragility, it is argued that (i) if the crystal entropy is significant ...

Network thermodynamics in the post-genomic era

Vassily Hatzimanikatis, Keng Cher Soh

Network models have been used to study the underlying processes and principles of biological systems for decades, providing many insights into the complexity of life. Biological systems require a constant flow of free energy to drive these processes that o ...

Vibrational entropy and the structural organization of proteins

Paolo De Los Rios, Francesco Piazza

In this paper we analyze the vibrational spectra of a large ensemble of non-homologous protein structures by means of a novel tool, that we coin Hierarchical Network Model (HNM). Our coarse-grained scheme accounts for the intrinsic heterogeneity of force c ...

BOLD correlates of EEG topography reveal rapid resting-state network dynamics

Dimitri Nestor Alice Van De Ville

Resting-state functional connectivity studies with fMRI showed that the brain is intrinsically organized into large-scale functional networks for which the hemodynamic signature is stable for about 10 s. Spatial analyses of the topography of the spontaneou ...

Dimerization of Dendrimeric Lanthanide Complexes: Thermodynamic, Thermal, and Liquid-Crystalline Properties

Kurt Schenk, Thomas Binderup Jensen

A series of 10 different mesomorphic semidendrimeric tridentate ligands L5-L14 grafted with terminal cyanobiphenyl groups have been synthesized. Upon reaction with Ln(NO3)(3) (Ln = trivalent lanthanide), the central 2,6-bis(N-ethylbenzimidazol-2-yl)pyridin ...
