The phase behavior of a DPPC monolayer on water was studied using vibrational sum-frequency spectroscopy (VSFG) in conjunction with fluorescence microscopy. A very sharp transition from a phase with curled alkyl chains to a phase with spatially extended ch ...
The problem of phase behaviour of solutions of globular proteins is approached by means of a Hard Core Yukawa fluid model with short-ranged attractions. We have determined the phase behaviour of this model system for different well widths, using a variety ...
In contrast with conventional networks, mobile ad hoc networks usually do not provide on-line access to trusted authorities or to centralized servers and they exhibit frequent partitioning due to link and node failures and to node mobility. For these reaso ...
Using both vibrational sum-frequency generation and fluorescence microscopy, the phase behaviour of a DPPC lipid monolayer on water is investigated as a function of surface pressure. The vibrational specificity of the sum-frequency generation techniques pe ...
We discuss the phase behaviour of spherical hard-core particles, with an attractive potential, as described by a hard-core Yukawa model. The ratio of the range of the attraction to the diameter of the particles is an important control parameter of the prob ...
This study analyses the location of patterns of brain activity in the signal space while a human subject is trained to operate a brain-computer interface. This evaluation plays an important role in the understanding of the underlying system, and it gives v ...
The spike timing in rhythmically active interneurons in the mammalian spinal locomotor network varies from cycle to cycle. We tested the contribution from passive membrane properties to this variable firing pattern, by measuring the reliability of spike ti ...
Equilibrium phase diagrams in composition-conversion space have been calculated for stoichiometric blends of an epoxy resin with a diamine hardener and dendritic hyperbranched polymers, to which various numbers of epoxy groups have been grafted. An attempt ...
The effective potential of the scalar field in the SU(5) model has extrema with symmetry:SU(5), SU(4)×U(1), SU(3)×SU(2)×U(1), SU(3)×[U(1)]2, [SU(2)]2×[U(1)]2. In our recent paper it was shown that the SU(4)×U(1) phase as well as SU(3)×SU(2)×U(1) phase were ...
Characteristics of hydrogels formed by assocn. of hydrophobically-modified polyethylene glycol (PEG) with fluoroalkyl (Rf) end-groups can be controlled by modulating their mol. structures. Polymers with relatively long PEG chains (e.g., 20 kg/mol PEG with ...
