Journal ArticleDOI
Compressed Sensing Electron Tomography for Determining Biological Structure
TL;DR: This article provides a link to the software that has been developed for CS-ET reconstruction of electron tomographic data sets, and suggests that such numerical recovery techniques for mitigating artifacts and denoising in reconstructions of fully sampled datasets remains advantageous.

TL;DR: The surface height distributions were measured with an interferometric microscope and complemented by atomic-force microscope measurements, to compute power spectral densities and then to evaluate the surface roughness and the effects of roughness in reducing the specular reflectivity were verified by soft-x-ray measurements.
Journal ArticleDOI
Mesospheric turbulent velocity estimation using the Buckland Park MF radar
TL;DR: In this article, the effects of transmitter beamwidths are investigated, confirm- ing the suggestions of previous authors that wide transmit beam widths lead to an overestimation of the turbulent veloc- ity.
Journal ArticleDOI
Analysis of the mass response of the electrochemical quartz-crystal nanobalance in horizontal and vertical geometry
TL;DR: In this paper, a holder for mounting a quartz-crystal resonator in an electrochemical polycrystalline nanobalance that is made of Teflon™ is presented.

Designing Fourier Descriptor-Based Geometric Models for Object Interpretation in Medical Images Using Genetic Algorithms
TL;DR: This work extends the complexity of the search object using 3D Fourier descriptor (FD) representations and allow GAs once again to optimize the object's shape and position and shows that the method is capable of coping with normal biological variation.
