TL;DR: In this article, the occurrence of chimera states for various coupling schemes in networks of two-dimensional and three-dimensional Hindmarsh-Rose oscillators, which represent realistic models of neuronal ensembles, was identified.
Abstract: We have identified the occurrence of chimera states for various coupling schemes in networks of two-dimensional and three-dimensional Hindmarsh–Rose oscillators, which represent realistic models of neuronal ensembles. This result, together with recent studies on multiple chimera states in nonlocally coupled FitzHugh–Nagumo oscillators, provide strong evidence that the phenomenon of chimeras may indeed be relevant in neuroscience applications. Moreover, our work verifies the existence of chimera states in coupled bistable elements, whereas to date chimeras were known to arise in models possessing a single stable limit cycle. Finally, we have identified an interesting class of mixed oscillatory states, in which desynchronized neurons are uniformly interspersed among the remaining ones that are either stationary or oscillate in synchronized motion.

TL;DR: A very sensitive hydrophobic assay for proteins (at the nanogram level) is developed using theHydrophobic reagents ammonium sulfate and trichloroacetic acid under pH conditions that increase neutral species concentration in the assay reagent in order to enhance the binding of more CBB dye molecules per protein molecule than in previous CBB-based assays.
Abstract: We investigated the mechanism of Coomassie brilliant blue G-250 (CBB) binding to proteins in order to develop a protein assay with the maximum possible sensitivity. We found that the neutral ionic species of CBB binds to proteins by a combination of hydrophobic interactions and heteropolar bonding with basic amino acids. On the basis of these findings, we developed a very sensitive hydrophobic assay for proteins (at the nanogram level) using the hydrophobic reagents ammonium sulfate and trichloroacetic acid under pH conditions that increase neutral species concentration in the assay reagent in order to enhance the binding of more CBB dye molecules per protein molecule than in previous CBB-based assays.

TL;DR: In this paper, the authors used the smaller alignment index (SALI) to distinguish rapidly and with certainty between ordered and chaotic motion in Hamiltonian flows, based on the different behaviour of the SALI for the two cases: the index fluctuates around non-zero values for ordered orbits, while it tends rapidly to zero for chaotic orbits.
Abstract: We use the smaller alignment index (SALI) to distinguish rapidly and with certainty between ordered and chaotic motion in Hamiltonian flows This distinction is based on the different behaviour of the SALI for the two cases: the index fluctuates around non-zero values for ordered orbits, while it tends rapidly to zero for chaotic orbits We present a detailed study of SALI’s behaviour for chaotic orbits and show that in this case the SALI exponentially converges to zero, following a time rate depending on the difference of the two largest Lyapunov exponents σ1 ,σ 2 ie SALI ∝ e −(σ
