13 In this paper, a user-defined inter-band correlation filter function was used to resample 14 hyperspectral data and thereby mitigate the problem of multicollinearity in classification 15 analysis. The proposed resampling technique convolves the spectral dependence information 16 between a chosen band-centre and its shorter and longer wavelength neighbours. Weighting 17 threshold of inter-ban...

This review investigates how laminar fMRI can complement insights into brain function derived from the study of rhythmic neuronal synchronization. Neuronal synchronization in various frequency bands plays an important role in neuronal communication between brain areas, and it does so on the backbone of layer-specific interareal anatomical projections. Feedforward projections originate predomina...

Internet gaming disorder (IGD) has many comorbid psychiatric problems including major depressive disorder (MDD). In the present study, we compared the neurobiological differences between MDD without comorbidity (MDD-only) and MDD comorbid with IGD (MDD+IGD) by analyzing the quantitative electroencephalogram (QEEG) findings. We recruited 14 male MDD+IGD (mean age, 20.0 ± 5.9 years) and 15 male M...

To explain gating of memory encoding, magnetoencephalography (MEG) was analyzed over multi-regional network of negative correlations between alpha band power during cue (cue-alpha) and gamma band power during item presentation (item-gamma) in Remember (R) and No-remember (NR) condition. Persistent homology with graph filtration on alpha-gamma correlation disclosed topological invariants to expl...

The discrete wavelet transform (DWT) has been widely used in scalable video coding for its advantages in multi-resolution analysis and subband decomposition. In this paper, a spatially scalable video coding system based on H.264 coding method and in-band overcomplete discrete wavelet transform (ODWT) technique is proposed, which integrates the good compression performance of H.264 in low freque...

Recent studies have shown that after partial spinal-cord lesion at the mid-cervical segment, the remaining pathways compensate for restoring finger dexterity; however, how they control hand/arm muscles has remained unclear. To elucidate the changes in dynamic properties of neural circuits connecting the motor cortex and hand/arm muscles, we investigated the cortico- and inter-muscular couplings...

We determine magnon spectra of an atomic bilayer magnet with ferromagnetic intra- and both ferro- anti- interlayer coupling. Analytic expressions for the full band latter case reveal that exchange interactions govern fundamental gap. The inter intralayer magnetic ordering are not independent: ferromagnetism stabilizes antiferromagnetic inter-layer order. topology these exchange-anisotropy spin ...

Oscillatory activity plays a critical role in the brain. Here, we illustrate the dynamics of neural oscillations in the motor system of the brain. We used a non-directional cue to instruct participants to prepare a motor response with either the left or the right hand and recorded electroencephalography during the preparation of the response. Consistent with previous findings, the amplitude of ...
