In proximity graphs to every pair of nodes it is assigned a certain vicinity, and the pair is connected if its vicinity is empty. In the automata studied here each node is characterized by a binary state and their updating is made according to a rule involving the neighborhood of each node. The effect of different types and degrees of memory of the past states embedded in nodes is assessed when...

Acoustic Emission (AE) was used to study the fracture of oxide grown on mild steel. Samples were oxidised and mechanically deformed in air at 550 OC using strain rates of -and lo-' s-' in a bend test furnace having a ceramic 4-point bend jig. The results were compared with earlier observations made on oxides deformed at room temperature. In both cases equidistant cracks formed and the crack spa...

Sperm flagella of the sea urchin Tripneustes gratilla beat with asymmetrical bending waves after demembranation with Triton X-100 in the presence of EGTA and reactivation at pH 8.1 with 1 mM ATP in the presence of 2 mM MgSO4. Addition of 0.1--0.2 mM free Ca2+ to these reactivated sperm induces 70--95% of them to become quiescent. This quiescence can be reversed by reduction of the free Ca2% con...

OBJECTIVE We determined whether the relationship between the neuropsychological performance of patients with mild traumatic brain injury (TBI) and their psychopathological characteristics measured by disability evaluation are interrelated. In addition, we assessed which psychopathological variable was most influential on neuropsychological performance via statistical clustering of the same char...

Simulated stormwater management devices baited with alfalfa infusion were constructed to test conveyance pipe dimension and orientation as a potential deterrent to mosquito oviposition. Various configurations of pipe diameter, length, and orientation were evaluated based on egg raft counts. Field trials tested pipes of 1.3-, 5-, and 10-cm diam and 0-, 90-, or 270-cm lengths, in both horizontal ...

The design and experimental demonstration of a large, ultrahigh-quality (Q) factor, single-mode operation silicon ring resonator based on strip photonic waveguide are presented. comprises multimode straight waveguides (MMWG), (SMWG), 90° Bezier bends, linear tapers. SMWG used in the coupling region to achieve mode for fundamental without exciting higher-order mode. MMWG, 1.6 μm width, decrease ...

A generic solver in a parallel Cartesian adaptive mesh refinement framework is extended to simulate detonations on three-dimensional structured curvilinear meshes. second-order accurate finite volume method used with grid-aligned Riemann solvers for thermally perfect gas mixtures. Detailed, multi-step chemical kinetic mechanisms are employed and numerically incorporated splitting approach. The ...

In premature neonates, with birth weights between 550 and 1250 g, short-term orotracheal intubation is routine. Despite the use of surfactant and steroids, 20% of these premature neonates develop pulmonary dysplasia, which requires an unpredictable ventilation period with an orotracheal tube.' 2 Placement of the orotracheal tube may extend from hours to months, and may result in midface changes...
