The purpose of this work is to analyse the trade-off between interference visibility and which-way information for a particle equipped with an internal degree of freedom, for example, spin. In such a general case, the interaction with an environment that acquires which-way information can ...
Small oligomers formed early along human islet amyloid polypeptide (hIAPP) aggregation is responsible for the cell death in Type II diabetes. The epigallocatechin gallate (EGCG), a green tea extract, was found to inhibit hIAPP fibrillation. However, the inhibition mechanism and the conformational di...
The GPCRs seem to be of critical importance to both the central nervous system and peripheral physiological processes. The GPCR superfamily is diverse and sequencing of the human genome has revealed >850 genes that encode them (Hopkins and Groom 2002, Nature Reviews Drug Discovery 1, 727-730)....
