The brain receives a rich flow of information which must be processed according to behavioral relevance. How is the state of the sensory system adjusted to up- or downregulate processing according to anticipation? We used magnetoencephalography to investigate whether prestimulus alpha band activity (8-14 Hz) reflects allocation of attentional resources in the human somatosensory system. Subject...

Using the Las Cumbres Observatory Global Telescope Network (LCOGT), we have obtained multi-epoch photometry of young cluster Mon R2. We monitored over 6000 sources with $i$-band between 13 and 23 mag within a $ 26'x26'$ field view. For each star, collected $\sim1500$ photometric points covering temporal window days. Based on these data, measured rotation-modulated 136 stars identified around 90...

This study examines the quantitative relationship between two natural serum antibodies, anti-band 3 and anti-alpha-galactosyl (anti-Gal), in their capacity to bind to human red blood cell (RBC) populations separated on density gradients. The question was approached in two ways. First, we determined the extent of rebinding of affinity-purified human serum antibodies to RBCs that had been strippe...

Neuroimaging has demonstrated anatomical overlap between covert and overt attention systems, although behavioral and electrophysiological studies have suggested that the two systems do not rely on entirely identical circuits or mechanisms. In a parallel line of research, topographically-specific modulations of alpha-band power (~8-14 Hz) have been consistently correlated with anticipatory state...

Emotion status influences important areas in our daily lives. Many researchers reported successful emotion classifications. The aim of this study is to find out the neurophysiological characteristics of the brain waves while affective pictures elucidate emotion. Four healthy college students volunteered the stimulus experiment with the standard IAPS affective pictures. All brain waves showed ac...

Electrons in $\ensuremath{\alpha}\text{\ensuremath{-}}{T}_{3}$ lattices behave as condensed-matter analogies of integer-spin Dirac fermions. The three atoms making up the unit cell bestow energy spectrum with an additional band that is completely flat, providing unique electronic properties. interatomic hopping term, $\ensuremath{\alpha}$, known to strongly affect two-dimensional (2D) lattice, ...

Hydrogenases catalyze the reversible activation of dihydrogen. We have previously demonstrated that the purified hydrogenase from the nitrogen-fixing microorganism Azotobacter vinelandii is an alpha beta dimer (98,000 Da) with subunits of 67,000 (alpha) and 31,000 (beta) daltons and that this enzyme contains iron and nickel. The enzyme can be purified anaerobically in the presence of dithionite...
