A eletrodeposição de filmes finos de um derivado da indenodiona em eletrodo de carbono vítreo modificado por nanotubos de carbono de paredes múltiplas (ECV-NTCPM), mostra um par de picos com características de confinamento em superfície. O eletrodo de carbono vítreo modificado por NTCPM e pela indenodiona (ECV-NTCPMI) apresenta uma alta atividade catalítica para a eletro-oxidação de hidroxilami...

Deployment of low power base station (pico) in macro cell is a key for providing high data rates. Cell range expansion is one of the features of LTE-advanced where low power base station in a heterogeneous network can increase their coverage area and neighboring cells can offload users to low power base station to reduce overload in macro cell. This presents a very challenging multi-user commun...

BACKGROUND Expression profiling, the measurement of all transcripts of a cell or tissue type, is currently the most comprehensive method to describe their physiological states. Given that accurate profiling methods currently available require RNA amounts found in thousands to millions of cells, many fields of biology working with specialized cell types cannot use these techniques because availa...

Heterogeneous networks (HetNets) have been considered as a promising architecture for upcoming 5G networks due to their high energy and spectrum efficiency. However, providing backhaul connectivity for all macro and pico base stations (BSs) in HetNets constitutes a significant share of infrastructure cost. Recently, the idea of flexible backhaul has drown a lot of attention both from industry a...

We report on a new beam-forming system for generating high intensity programmable optical spikes using so-called matched-filtering Generalized Phase Contrast (mGPC) applying two consumer handheld pico-projectors. Such a system presents a low-cost alternative for optical trapping and manipulation, optical lattices and other beam-shaping applications usually implemented with high-end spatial ligh...

In order to resolve the co-channel inter-cell interference problem in heterogeneous networks (HetNet), the feature of almost blank subframes (ABS) in the time domain of the enhanced inter-cell interference coordination (eICIC) is utilized. In this paper, an ABS configuration design is developed on downlink in HetNet and the associated resource allocation problem for maximizing the system perfor...

The previous year was another great success for the open source integrated circuit (IC) design ecosystem. It finished with two actions: second IEEE Solid-State Circuits Society (SSCS) PICO IC contest, known as the Chipathon , and first Code-a-Chip travel grant award. Chipathon installment in 20...
