The different views from small angles.
T he small-angle scattering of xrays or neutrons from proteins in solution can provide important information about the structure of the protein and the nature of interactions or distance correlations among the protein molecules (1, 2). The former is encoded in the form factor [P(q)], and the latter in the structure factor [S(q)]. These functions are of great interest to the structural biology c...
متن کاملIridescence: views from many angles.
Iridescent colours have been fascinating to humans throughout history; they are flashy, shimmering, dynamic, and examples surround us, from the commonly seen iridescent sheen of oily street puddles to the exotic, gaudy displays of birds-of-paradise featured in nature documentaries. Iridescent colours and the structures that produce them have unique properties in comparison with other types of c...
متن کاملSN2002es-LIKE SUPERNOVAE FROM DIFFERENT VIEWING ANGLES
In this letter, we compare optical light curves of two SN2002es-like Type Ia supernovae, iPTF14atg and iPTF14dpk, from the intermediate Palomar Transient Factory. Although the two light curves resemble each other around and after maximum, they show distinct early-phase rise behavior in the r -band. On the one hand, iPTF14atg revealed a slow and steady rise which lasted for 22 days with a mean r...
متن کاملFundamental Physical Constants: Looking from Different Angles
We consider fundamental physical constants which are among a few of the most important pieces of information we have learned about Nature after its intensive centurieslong studies. We discuss their multifunctional role in modern physics including problems related to the art of measurement, natural and practical units, origin of the constants, their possible calculability and variability etc. PA...
