Nanocomposite thin film deposited on copper and glass substrates have been created by utilizing Spray Pyrolysis method. The prec...

We investigated the distribution of bioluminescent dinoflagellates in the Patagonian Shelf region using "universal" PCR primers for the dinoflagellate luciferase gene. Luciferase gene sequences and single cell PCR tests, in conjunction with taxonomic identification by microscopy, allowed us to identify and quantify bioluminescent dinoflagellates. We compared these data to coincidental discrete ...

Despite the benefits of composite structures, it is only recently that the main load bearing structures in large aircraft such as the Boeing 787 and Airbus A350 have started to be manufactured using carbon fibre composites. Even then, the unique directionality properties of composite laminates and design possibilities have yet to be exploited to improve the aircraft performance. In this study a...

This paper addresses the boundary control for flutter suppression of a flexible wing, both in bending and twisting displacements, under unsteady aerodynamic loads. The wing is modeled by a distributed parameter system described as two coupled partial differential equations. The problem is tackled in the framework of semigroup theory, and a Lyapunov-based stability analysis is carried out to ass...

We unveil a new luminescent assay using 11-mercaptoundecanoic acid-bound Au nanodots (11-MUA-Au NDs) for the highly selective and sensitive detection of hydrogen peroxide and glucose, based on luminescence quenching.

Observational data (i.e., data that records observations and measurements) plays a key role in many scientific disciplines. Observational data, however, are typically structured and described in ad hoc ways, making its discovery and integration diÆcult. The wide range of data collected, the variety of ways the data are used, and the needs of existing analysis applications make it impractical to...

Radiative recombination in degenerately n-doped InP nanowires is studied for excitation above and below the Fermi energy of the electron gas, using photoluminescence. Laser-induced electron heating is observed, which allows absorption below the Fermi energy. We observe photon upconversion where photo-excited holes recombine with high |k| electrons. This can be attributed to hole scattering to h...

Detection of atrial activity (AA) is quite important in the study and monitoring of atrial rhythms, in particular atrial flutter and atrial fibrillation (FA). An efficient noninvasive study of the AA needs the ventricular activity cancellation. The Discrete Packet Wavelet Transform (DPWT) allows the decomposition of the original ECG in a set of coefficients with different temporal and spectral ...

A series of new ligands suitable for the formation of luminescent lanthanide complexes in water is described. The chelates are designed for analyte labeling and play the role of fluorescent donor in homogeneous time-resolved fluorescence assays using LEDs as a light source for excitation at 370 nm. Ligands are constructed from a coumarin nucleus, for lanthanide sensitization, and different amin...
