In this paper, we study the long-time behavior of solutions single-layer quasi-geostrophic model arising from geophysical fluid dynamics. We obtain lower bound decay estimate solution. Utilizing Fourier splitting method, under suitable assumptions on initial data, for any multi-index α, show that solution Ψ satisfies

Parallel Wireless Communications area of research that enables mobile clients to multiple wireless networks concurrently. This concurrent bandwidth aggregation techniques t wireless communications on mobile devic aggregation can be performed using wireless device or cooperatively across devices within w of each other.. The aggregation can be a application-layer, transport layer like Multi layer...

in this paper, the accuracy of k- and k- turbulence models in super sonic boundary layer capturing of smooth/rough flat plates have been comprehensively investigated. among these investigations, some sorts of sensitivity analysis, including change in turbulence model, generated-grid density, near wall affects, c magnitude (for boundary layers generated on smooth flat plates), and change in c...

A series of experiments is presented that model the generation of internal gravity waves in the ocean by the forcing of turbulent eddies in the surface mixed layer.The experimental setup consists of a shallowmixed upper layer and a deep continuously stratified lower layer. A source of turbulence is dragged through the upper layer. Internal waves can freely propagate in the lower layer. The inte...

A probe-fed circularly polarized 3-layer stacked patch antenna is presented and simulated by using Commercial Ansoft High Frequency Structure Simulator. The design consists of three patches and three substrates. The lower and middle patches are of square-shaped where as the upper patch is of triangular-shaped. One slot is inserted in the lower layer, two slots are inserted in the middle layer a...

Anaerobic ammonium oxidizing (anammox) bacterial community structures were investigated in surface (1-2 cm) and lower (20-21 cm) layers of mangrove sediments at sites located immediately to the mangrove trees (S0), 10 m (S1) and 1000 m (S2) away from mangrove trees in a polluted area of the Pearl River Delta. At S0, both 16S rRNA and hydrazine oxidoreductase (HZO) encoding genes of anammox bact...

We present a deep learning model for hierarchical image representation in which we build the hierarchy by stacking up the base models layer by layer. In each layer, the base model receives the features of the lower layer as input and produces a more invariant and complex representation. The bottom layer receives raw images as input and the top layer produces an image representation that can be ...

We studied the morphologic effect of low mechanical stresses (compression, tension and neutralization) on the growth cartilage with an external fixator in 18 young lambs. On radiography, we only found more length in the femora subjected to tension (P < 0.05). Bony bridges were not present, nor were there signs of altered vascularization or Ranvier's perichondral ring. Histomorphometrically, in ...

The sites of termination of afferents from the lateral geniculate nucleus to layer IV and lower layer III in area 17 of the rat visual cortex have been determined by use of a combined degeneration--Golgi/EM technique. Degeneration of geniculocortical axon terminals was produced by making lesions in the lateral geniculate body. After the animals had been allowed to survive for two days, the ipsi...
