Noisy teleportation of nonclassical quantum states via a two-mode squeezed-vacuum state is studied with the completely positive map and the GlauberSudarshan P -function. Using the nonclassical depth as a measure of transmission performance, we compare the teleportation scheme with the direct transmission through a noisy channel. The noise model is based on the coupling to the vacuum field. It i...

Detecting the region of emergent events is an important application of wireless sensor networks (WSN). One of the key challenges in detecting event in a WSN is how to detect it accurately while transmitting minimum information to provide sufficient details about the event. In this paper, an aggregation algorithm based on splay tree is proposed to achieve the following goals: monitoring data of ...

Most congenital transmissions of Trypanosoma cruzi are not detected. As the levels of mediators regulating the immune response might be different in the absence or in the presence of transmission, we explored the levels of tumor necrosis factor (TNF) and soluble TNF receptors TNF-R1 and -R2 in T. cruzi-infected pregnant women and the neonates. We previously found that the circulating levels of ...

A wavelet coding method for image data on arbitrarily shaped support applicable to the object-oriented coding of moving pictures, and to the efficient representation of texture data in computer graphics is proposed. Wavelet transform of arbitrarily shaped image is obtained by applying symmetrical extension technique at region boundaries and keeping the location of wavelet coefficient. For the e...

We study the problem of transmitting a Gaussian source with memory to a digital and a linear-analog receiver, over an arbitrarily colored, non-degraded Gaussian broadcast channel. The main result of this work is a complete characterization of the set of achievable distortion pairs at the two receivers given a power constraint at the transmitter. Further, we show a constructive hybrid uncoded-co...
