The effect of the visual hemifield to which spatial attention was oriented on the activities of the posterior parietal and occipital visual cortices was examined using functional near-infrared spectroscopy in order to investigate the neural substrates of voluntary visuospatial attention. Our brain imaging data support the theory put forth in a previous psychophysical study, namely, the attentio...

Optical and near-infrared spectroscopic observations of the fast nova V1494 Aquilae 1999 # 2 covering various phases – early decline, transition and nebular – during the first eighteen months of its post-outburst evolution are presented in this paper. During this period, the nova evolved in the PfeP o fe Co spectral sequence. The transition from an optically thick wind to a polar blob equatoria...

source localization is an essential part of array signal processing including radar, sonar, seismology and oceanography applications. the performance of the presented source localization methods are degraded substantially in practical situations. one of the conditions which decreases the performance o

In the past few years, technology for children and disabilities has proliferated thanks to the development of more and more inexpensive mobile technology and to the availability of freedownloadable software applications. However, at our knowledge a multisensory teaching application for both normal and disabled children still lacks in this landscape. In this work we describe the design and devel...

By using the substituent effect to tune the palladium(II)-involved reactivity, a new probe is found to respond quantitatively to Pd(II). Unexpectedly, the probe gave an emission band in the desirable near-infrared (NIR) region (780 nm), thus providing the first NIR sensor for palladium detection.

Near-infrared (NIR) spectroscopy in diffuse reflectance mode was explored with the objective of discriminating sea salts according to their quality type (traditional salt vs "flower of salt") and geographical origin (Atlantic vs Mediterranean). Sea salts were also analyzed in terms of Ca(2+), Mg(2+), K(+), alkalinity, and sulfate concentrations to support spectroscopic results. High concentrati...

Alzheimer’s disease makes great demands on care by caregivers, since they cannot distract their attention from patients while they are managing records at the same time. For this reason, technologies to complement this process need to be considered. In this work we propose to adapt Near Field Communications (NFC), applying it to an Alzheimer’s day centre. With a simple interaction, which involv...
