Wiener Polarity Index of Tensor Product of Graphs
Mathematical chemistry is a branch of theoretical chemistry for discussion and prediction of the molecular structure using mathematical methods without necessarily referring to quantum mechanics. In theoretical chemistry, distance-based molecular structure descriptors are used for modeling physical, pharmacologic, biological and other properties of chemical compounds. The Wiener Polarity index ...
متن کاملCell polarity: Fixing cell polarity with Pins
A protein complex is assembled in a step-wise manner at the apical pole of Drosophila neuroblasts. This complex organizes the apical-basal polarity of asymmetrically dividing neuroblasts, and may act via G-protein signalling.
متن کاملSticky polarity
Research Roundup Research Roundup for example, two nearby cells can somehow tell which one is closer to the equator (middle) of the eye, and specify the R3 (equatorial) and R4 (polar) fates, accordingly. " This is one of the great puzzles of PCP, " says Simon. " The cells are reading the gradient rather than the absolute values, and sensing the smallest differences. " For that process to have a...
متن کاملCell polarity
The Minisymposium on Cell Polarity featured a broad array of systems. The session began with talks on asymmetric cortical polarity cues. Lesilee Rose (University of California, Davis) discussed asym-metric division in Caenorhabditis elegans. In the one-cell embryo, PAR polarity proteins regulate cytoplasmic polarity and cortical forces that position the spindle. The latter require the DEP domai...
متن کاملNeuronal polarity.
The assembly of functional neuronal networks in the developing animal relies on the polarization of neurons, i.e., the formation of a single axon and multiple dendrites. Breaking the symmetry of neurons depends on cytoskeletal rearrangements. In particular, axon specification requires local dynamic instability of actin and stabilization of microtubules. The polarized cytoskeleton also provides ...
