Neural nets on the MPP

The Massively Parallel Processor (MPP) is an ideal machine for computer experiments with simulated neural nets as well as more general cellular automata. Experiments using the MPP with a formal model neural network are described. The results on problem mapping and computational efficiency apply equally well to the neural nets of Hopfield, Hinton et al., and Geman and Geman

A method for predicting full scale buffet response with rigid wind tunnel model fluctuating pressure data. Volume 1: Prediction method development and assessment

The method requires unsteady aerodynamic forces, natural airplane modes, and the measured pressure data as input. A gust response computer program is used to calculate buffet response due to the forcing function posed by the measured pressure data. By calculating both symmetric and antisymmetric solutions, upper and lower bounds on full-scale buffet response are formed. Comparisons of predictions with flight test results are made and the effects of horizontal tail loads and static aeroelasticity are shown. Discussions are also presented on the effects of primary wing torsion modes, chordwise and spanwise phase angles, and altitude

Láser y luz pulsada intensa en el tratamiento de hemangiomas infantiles y malformaciones vasculares

The use of the indications of the laser in treating vascular malformations and infantile haemangiomas is based on the theory of selective photothermolysis, in which the oxyhaemoglobin is the target chromophore on which the light of the laser acts, thus avoiding damage to neighbouring tissues. The pulsed dye laser is the most employed and at present is the treatment of choice in capillary malformations (port-wine stains). A variable response is obtained, with a substantial clearing of the colour of the lesion after several sessions. Application at early ages seems to improve the results. Venous malformations, especially those localised in the mucosa, respond better to the Nd:YAG laser; lymphatic malformations to the CO2 laser. Arteriovenous malformations rarely respond. Use of the pulsed dye laser in the phase of proliferation of the haemangiomas is subject to controversy, except where there is ulceration. A rapid re-epithelialization is obtained in these cases following its use. In the involution phase, patients with residual vascular lesions can benefit from other lasers such as KTP or Nd:YAG. If they show an atrophic surface and scars these complications improve with the CO2 laser or Er:YAG. New treatment modalities are emerging, such as photodynamic therapy, whose efficacy and safety, both in the treatment of haemangiomas and vascular malformations, have yet to be confirmed

A method for predicting full scale buffet response with rigid wind tunnel model fluctuating pressure data. Volume 2: Power spectral densities for method assessment

The predicted upper and lower bounds power spectra for all of the cases and response items given in Volume 1 are plotted. The flight test power spectra are shown on each prediction plot for the nominal value of angle of attack that most closely agrees with the flexible angle for the prediction. The flight test and prediction conditions are given in tabular form for all cases considered

Molecular evidence for Anaplasma phagocytophilum in Israel

Sequences from the Anaplasma phagocytophilum 16S rRNA gene were detected in 5 ticks representing 3 species (Hyalomma marginatum, Rhipicephalus turanicus, and Boophilus kohlsi) collected from roe deer (Capreolus capreolus) in Mount Carmel, Israel. The sequences were all identical to those of Ap-variant 1 strain
