The problem of diffraction of a plane scalar wave by a narrow cone is considered. The shape of the cone is arbitrary. The boundary condition is the Dirichlet or Neumann one. The wave scattered by the cone vertex arises as a result of the diffraction process. The subject of this paper is...
Lens MTF response can never exceed the diffraction-limited response, but system MTF response often exceeds it at medium spatial frequencies as a result ofsharpening, which is (and should be) present in most digital imaging systems. In addition to lens response, system MTF response is affected by...
In contrast, the axial dimension of the Airy disk forms an elliptical pattern that often referred to as the point-spread function (PSF). The elongated geometry of the point-spread function along the optical axis arises from the nature of the non-symmetrical wavefront that emerges from the ...
Since the Bragg condition is only rarely and discretely fulfilled, X-ray diffraction of a single crystal with monochromatic X-rays requires data collection at several different angles; thus, the need to rotate the sample under the beam arises (Fig. 21.2). Determining the complete atomic structure...
The angular dispersion can therefore be used as a figure of merit, but it must be remembered that the parameter of ultimate importance is the grating resolution divided by the axial mode spacing of the external cavity. (For a detailed description of multiple-prism grating dispersion, see Chapter...
in connection with which the necessity arises of considering the problem of diffraction of fluctuating radiation. In [1] one such problem was considered - namely the char- acteristics of back-scattering of an ideally reflecting cylinder situated behind a layer having random inho- mogeneities wer...
Although peak positions are similar, there is significant noise in peak intensities due to difference in impurities and as a result many overlapping peaks. Full size image The second evaluation dataset is the MP Dataset, which contains 2253 inorganic crystal materials obtained from the Materials ...
Then a question arises whether the myosin heads discussed here are the “troponin bridges” bound at the position of troponin rather than at the target zone. Actually the 3-D map in Fig. 5E is a repeating unit and it is also true that there are a hot spot and a cool spot on the ...

Keeping in mind the factor x2 dx/x, which arises from phase space, we see that this term is indeed proportional to x4 dx/x, as it appears in Eq. (8). The soft-radiation limit of the first term corresponds to z = (1 − x) ≪ 1. Then the third jet carries the largest ...
