Scattering Functions and Correlation Functions of Random Knots
For random knots, we discuss correlation functions and scattering functions, which are fundamental in the statistical mechanics of ring polymers. Random knots gives a theoretical model for a ring polymer with fixed knot in solution at the θ temperature. We introduce a model function for the probability distribution of distance between two nodes in random polygon with fixed knot. We then perform...
متن کاملQuasi-elastic Scattering of Neutrons
In solids random motions of atoms may take place in connection with disorder; for instance diffusion of interstitials in solid solutions or orientation fluctuations in molecular solids. Experimentally these motions are observed mostly by resonance and relaxation techni ques, by optical spectroscopy and, recently, by neutron spectroscopy. In comparison to the other me thods neutron spectroscop...
متن کاملMultiple scattering and modified Green’s functions
Exterior boundary-value problems for the Helmholtz equation can be reduced to boundary integral equations. It is known that the simplest of these fail to be uniquely solvable at certain ‘irregular frequencies.’ For a single smooth scatterer, it is also known that irregular frequencies can be eliminated by using a modified fundamental solution, one that has additional singularities inside the sc...
متن کاملa contrastive study of rhetorical functions of citation in iranian and international elt scopus journals
writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...
On the Magnetic Scattering of Neutrons
forenoon but failed on June 19. Weak transmission by scattered reflections also failed. Absorption of Ftransmission from WSXAL (6060 kc/s, 650 km distant) was greater than normal on June 19. The F2 virtual heights were very high when fz,* began to increase above fp, * from 1400 to 1600 EST June 19. This example of correlation of the condition of the ionosphere with a magnetic storm corroborates...
