Introduction: Catecholamines are charged neurotransmitters found in the neuroendocrine cells called chromaffins. The release of catecholamine, through a narrow fusion pore of a chromaffin cell requires a charge compensation by other ions to maintain an osmotic balance of charges. The aim of this research is to show that the exocytotic catecholamine release is not associated with the cation flux...

Two novel cyclic quaternary amine crosslinking probes are synthesized for structural mass spectrometry of protein complexes in solution and for analysis of protein interactions in organellar and whole cell extracts. Each exhibits high aqueous solubility, excellent protein crosslinking efficiencies, low collision induced dissociation (CID) energy fragmentation efficiencies, high stoichiometries ...

In the title compound, C(6)H(8)NO(+)·C(3)H(3)O(4) (-), the amino N atom is protonated, and one of the carboxyl groups is deprotonated to maintain the charge balance. In the crystal, classical N-H⋯O and O-H⋯O hydrogen bonds connect the ions into a two-dimensional network parallel to the ac plane. In addition, the structure is further stabilized by C-H⋯O and π-π inter-actions [centroid-centroid d...

We study the three string junctions and string networks in Type IIB string theory by explicity constructing the holomorphic embeddings of the M-theory membrane that describe such configurations. The main feature of them such as supersymmetry, charge conservation and balance of tensions are derived in a more unified manner. We calculate the energy of the string junction and show that there is no...

A novel state of matter has been hypothesized to exist during the early stage of relativistic heavy-ion collisions, with normal hadrons not appearing until several fm/c after the start of the reaction. To test this hypothesis, correlations between charges and their associated anticharges are evaluated with the use of balance functions. It is shown that late-stage hadronization is characterized ...

In this paper, the introduction of a homeostatic regulation mechanism in a vision system is proposed. This homeostatic mechanism takes charge of controlling the luminance, white balance, contrast and size of the object of interest in the image, using naive methods except for the contrast, for which we have implemented a method that avoids the hill climbing search for the best focus position. We...

In the title compound, (C7H11N2)3[Fe(NCS)6]·H2O, the Fe(III) cation is coordinated by six terminal N-bonded thio-cyanate anions into a discrete threefold negatively charged complex. Charge balance is achieved by three protonated 4-(dimethyl-amino)-pyridine cations. The asymmetric unit consists of one Fe(III) cation, six thio-cyanate anions, three 4-(dimethyl-amino)-pyridinium cations and one wa...

Fluctuations of thermodynamic quantities are fundamental for the study of the QGP phase transition. The ALICE experiment is well suited for precise event-by-event measurements of various quantities. In this article, we review the capabilities of ALICE to study the fluctuations of several key observables such as the net charge, the temperature, and the particle ratios. Among the observables rela...

The anion of the title complex, Cs(2)[PuCl(4)O(2)], adopts a pseudo-octa-hedral geometry (2/m crystallographic site symmetry) with two plutonyl oxide ligands in axial sites and four chloride ligands occupying the equatorial plane. Charge balance is maintained by two caesium cations per tetra-chlorido-dioxido-plutonate(VI) anion. Principal bond lengths include Pu-O = 1.752 (3) Å and Pu-Cl = 2.66...

Gravitational field in general relativity is a manifestation of spacetime curvature and (unlike the electromagnetic field) is not a force field. A body falling toward the Earth is represented by a geodesic worldline which means that no force is acting on it. If a body is on the Earth’s surface, however, its worldline is no longer geodesic and it is subjected to a force. The nature of that force...
