Fermi coordinates (FC) are supposed to be the natural extension of Cartesian coordinates for an arbitrary moving observer in curved space-time. Since their construction cannot be done on the whole space and even not in the whole past of the observer we examine which construction principles are responsible for this effect and how they may be modified. One proposal for a modification is made and ...

BACKGROUND Interstitial lung disease (ILD) is a large group of diseases, including hypersensitivity pneumonitis (HP), idiopathic pulmonary fibrosis (IPF) and sarcoidosis. OBJECTIVE In this study, we aimed to identify bronchoalveolar lavage fluid (BALF) biomarkers which could be contributive for HP diagnosis. METHODS We analyzed 39 BALF samples from 12 ILD patients with sarcoidosis, 11 with ...

Owing to the inhomogeneity and ill defined edges present in images, the incorporation of prior knowledge into level set models, in image segmentation, is a field of active researches. In this paper, a new way of incorporating prior information to constrain the evolution of the level set model during the segmentation is presented. This technique allows resolving the problem of applying the same ...

AIM Maspin is a unique serine proteinase inhibitor which has tumor suppressor activity. The aim of the present study was to investigate the role of maspin in ampullary adenocarcinomas, its correlation with apoptosis and its value as a prognostic marker. PATIENTS AND METHODS Twenty-three cases of ampulla of Vater adenocarcinoma were collected from archival material. For each sample, maspin, M3...

A forest is the clique complex of a strongly chordal graph and a quasiforest is the clique complex of a chordal graph. Kruskal–Katona type theorems for forests, quasi-forests, pure forests and pure quasi-forests will be presented. Introduction Recently, in commutative algebra, the forest ([5]) and the quasi-forest ([17] and [9]) have been extensively studied. Each of these concepts is, however,...
