which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited. Microscopic colitis (MC) is characterized by chronic watery diarrhea. MC comprises two entities: collagenous colitis (CC) and lymphocytic colitis (LC), which are separated by typical histopathological characteristics. The colonic mucosa appears endoscopicall...

The microscopic structure and anisotropy of plant cell walls greatly influence the mechanical properties, morphogenesis, and growth of plant cells and tissues. The microscopic structure and properties of cell walls are determined by the orientation and mechanical properties of the cellulose microfibrils and the mechanical properties of the cell wall matrix. Viewing the shape of a plant cell as ...

Pre-neutron fragment-yield distributions are calculated for the U(n, f) and Pu(n, f) reactions using a time-dependent fully microscopic approach. These yields are calculated as a function of incident neutron energy from thermal to 5 MeV. We show that our calculations are in good agreement with experimental results, and competitive in accuracy with more phenomenological approaches. Further impro...

We show that the scaling procedure, recently proposed for the evaluation of the temperature variation of the normalized upper critical field of type-II superconductors, may easily be modified in order to take into account a possible temperature dependence of the Ginzburg-Landau parameter κ. As an example we consider κ(T ) as it follows from the microscopic theory of superconductivity.

For a better understanding of the dynamics of exotic nuclei it is of crucial importance to develop a practical microscopic theory easy to be applied to a wide range of masses. Theoretically the basic task consists in formulating an easy solvable theory able to reproduce structures and transitions of known nuclei which should be then used to calculate the sparely known properties of protonor neu...

A polarizable quantum mechanics and molecular mechanics model has been extended to account for the difference between the macroscopic electric field and the actual electric field felt by the solute molecule. This enables the calculation of effective microscopic properties which can be related to macroscopic susceptibilities directly comparable with experimental results. By separating the discre...

How do the microscopic properties of a photoreceptor shape the transformation of photon inputs into electrical outputs? Adaptive feedback, combined with stochastic sampling of light by transduction units, efficiently captures visual information.

The feasibility and extraordinary properties of mirrorless optical parametric oscillations in a microscopic strongly absorbing slab of negative-index metamaterial are shown. They stem from the backwardness of electromagnetic waves inherent with this type of metamaterial.
