Because the need to classify objects with respect to uncertain properties is increasing, it becomes important to seek an appropriate generalization of a Galois lattice structure. We aim to analyze an uncertain (probabilistic) Galois lattice structure. One of our interests consists to determine a complete (total) order within the objects set generated by the uncertain Galois lattice structure. A...

Introduction: Tympanoplasty is the standard and well established procedure for closure of tympanic membrane perforations .This paper compares the results of tympanoplasty in terms of hearing improvement and graft incorporation in patients with chronic perforation of the tympanic membrane between two groups with and without active drainage at the time of surgery.  Materials and Methods: Sixty re...

Experiments conducted on solid-state ionic membranes that convert atoms into ions that can in turn be extracted into energetic beamlets and thereby produce thrust are described. The capability of ionizing and transporting ions is shown to be both rapid (over 10 mA/cm) and efficient (of order 1 eV/ion). Although similar in appearance to cesium contact sources, solid-state ionic membrane devices ...

Nowadays, membrane processes are widely used for high purity Nitrogen production. Separation of air by membranes is a flexible process in which the investment and operational costs are lower than for example adsorption or cryogenic processes. Such processes are based on relative permeability of air components which are transported by the pressure difference between two sides of the membrane. M...

Pex19p is a protein required for the early stages of peroxisome biogenesis, but its precise function and site of action are unknown. We tested the interaction between Pex19p and all known Pichia pastoris Pex proteins by the yeast two-hybrid assay. Pex19p interacted with six of seven known integral peroxisomal membrane proteins (iPMPs), and these interactions were confirmed by coimmunoprecipitat...

The main contribution of this paper is the introduction of the new concept of membrane controller based on the structure and functioning of a deterministic numerical P system. The procedure for developing a membrane controller and for using it to control a mobile robot is explained and several test cases are given in which membrane controllers are used to control both simulated and real mobile ...

Chitin is a major molecular pattern for various fungi, and its fragments, chitin oligosaccharides, are known to induce various defense responses in plant cells. A plasma membrane glycoprotein, CEBiP (chitin elicitor binding protein) and a receptor kinase, CERK1 (chitin elicitor receptor kinase) (also known as LysM-RLK1), were identified as critical components for chitin signaling in rice and Ar...

The concept of the paucimolecular membrane derived in the first place from studies, such as those of Gorter and Grendel, on the azmourit of fatty material that could be extracted from the cell, based on the assumption that this was mainly concenitrated at its surface. These studies, and other ones, led to the concept of the bimolecular leaflet of lipid as the fundamental basis of membrane struc...

The precise nature and role of a charge-selectivity barrier, existing at the level of the glomerular capillary wall has been the subject of continuing controversy since it was first postulated over 30 years ago. Recent studies suggest that some earlier observations may have been overinterpreted and that the conclusions reached should be re-examined. The concept of a charge-selectivity barrier a...
