This paper presents a case study in implementing a moderately complex, useful service on an active network platform. The active application is reliable multicast with congestion control; the platform comprises the Bowman Node Operating System and the Composable Active Network Elements (CANEs) Execution Environment. The importance of the work stems from the lessons it provides about the design a...

The black-eyed pea trypsin and chymotrypsin inhibitor (BTCI) is a member of the Bowman-Birk protease inhibitor (BBI) family. The three-dimensional model of the BTCIchymotrypsin complex was built based on the homology to Bowman-Birk inhibitors with known structures. An extensive theoretical and experimental study of these known structures has been performed. The model confirms the ideas about Bo...

PURPOSE To determine the UV absorbance of the corneal layers (epithelium, Bowman layer, stroma) in the 240- to 400-nm range. METHODS Consecutive slices (100 microm) of human cadaveric corneas were cut, and the UV absorbance of each sample was determined in a scanning spectrophotometer. In some cases the epithelium was scraped off and its absorbance measured separately. RESULTS The investiga...

The calculation of infrared spectra by molecular dynamics simulations based on the AMOEBA polarizable force field has recently been demonstrated [Semrouni et al., J. Chem. Theory Comput., 2014, 10, 3190]. While this approach allows access to temperature and anharmonicity effects, band assignment requires additional tools, which we describe in this paper. The Driven Molecular Dynamics approach, ...

purpose: to evaluate and compare tear secretion and tear film instability following laser in situ keratomileusis (lasik) and laser assisted subepithelial keratectomy (lasek). methods: in a randomized clinical trial, 30 eyes of 15 patients underwent lasik and 30 eyes of 15 patients underwent lasek to correct myopia. tear secretion and tear film instability were tested preoperatively, 2 and 6 wee...

purpose : to assess and to compare stromal and endothelial changes at the cellular level in patients who had photorefractive keratectomy (prk) and laser in situ keratomileusis (lasik) using in vivo confocal microscopy methods : in this semiexperimental study, 32 eyes of 16 patients (4 males and 12 females) with low to moderate myopia [-1.00 to -4.50 diopters (d)] or low to moderate myopic astig...
