Two-dimensional magnets are promising for nanoscale spintronic applications. Currently, most available candidates based on $3d$ transition metal compounds, with hexagonal or honeycomb lattice geometry. Here, a GdCl$_3$ monolayer $4f$ moments is theoretically studied, which can be exfoliated from its existing bulk. Its orthorhombic structure and hendecahedral ion cages unique in two-dimensional....

A novel optical coherence tomography (OCT) reconstruction approach is introduced for improved visualization of inner-retina capillaries in retinal OCT tomograms. The proposed method utilizes a minimization framework based on a tensor total variation (TTV) energy functional, to enforce capillary structural characteristics in the spatial domain. By accounting for structure tensor characteristics,...

Zernike phase contrast cryo-electron microscopy (ZPC-cryoEM) is an emerging technique that is capable of producing higher image contrast than conventional cryoEM. By combining this technique with advanced image processing methods, we achieved subnanometer resolution for two biological specimens: 2D bacteriorhodopsin crystal and epsilon15 bacteriophage. For an asymmetric reconstruction of epsilo...

Electron tomography (ET) has emerged as the leading technique for three-dimensional (3D) structural analysis of unique complex biological specimens. ET makes it possible to directly visualize the molecular architectures of organelles, cells and complex viruses at close-to-molecular resolution. ET has been crucial to reveal some of the major breakthroughs in life sciences in the last few years. ...

In this work we present a logical reconstruction of Leonard Bloomfield’s theory of structural linguistics. First, the central notions of this theory are analyzed and discussed. In the following section, a reconstruction with the so-called structuralist approach in the philosophy of science is presented. After defining the general framework of Bloomfield’s theory, questions of lawlikeness and th...
