Applying the finite-element method, we analyze stress-strain state of three-dimensional solids bounded by cylindrical surfaces with directrices in form confocal ellipses. In this case, use an elliptic coordinate system to deduce resolving equations. We also compare displacements a noncircular cylinder for different values semiaxes ellipses cross section.

In this paper, a reweighted sparse representation algorithm based on noncircular sources is proposed, and the problem of the direction of arrival (DOA) estimation for multiple-input multiple-output (MIMO) radar with mutual coupling is addressed. Making full use of the special structure of banded symmetric Toeplitz mutual coupling matrices (MCM), the proposed algorithm firstly eliminates the eff...

The detection of a known signal with unknown parameters in the presence of noise plus interferences (called total noise) whose covariance matrix is unknown is an important problem which has received much attention these last decades for applications such as radar, satellite localization or time acquisition in radio communications. However, most of the available receivers assume a second order (...

Curved DNA molecules and unusually small circles have been obtained by ligation of synthetic 21-base precursors: (sequence in text). The ligation resulted in the formation of double-stranded oligo-(precursor)s possessing a strong 10.5-base-pair (bp) periodicity of the runs of adenines. Two-dimensional polyacrylamide gel electrophoresis of the ligation products showed two distinct families of sp...

In models of the replication of human hepatitis delta virus (HDV) RNA, it is generally assumed that circular RNAs are the only templates. However, noncircular HDV RNAs are also produced during replication, and it is known that replication can be initiated by transfection with noncircular RNAs. Therefore, strategies were devised to determine the relative ability of different HDV RNA species to i...

The current experiments examined the effect of healthy aging on the integration of orientation and position information in shape perception. Following Day and Loffler (2009), conflicting contours were created by sampling the orientations of one shape (e.g., a rounded pentagon) with Gabors, and positioning them on the circumference of a different shape (e.g., a circle). In Experiment 1, subjects...
