Titanium (Ti) alloys are widely used in tissue engineering, but their applications are limited by low strength, bactericidal properties, and metal ion release. Beta Ti alloys are promising materials for load‐bearing orthopedic implants due to their excellent corrosion resistance and high biocompatibility. Herein, developed new beta‐Ti alloys including Ti–Nb–Zr–Sn (Ti–Sn) and Ti–Nb–Zr–Ta–Si (Ti–Si)...

Background A possible relationship between periodontitis and Alzheimer’s disease (AD) has been reported. However, there is limited information on the association between the Porphyromonas gingivalis (P. gingivalis) periodontal infection and the pathological features of AD. The hypothesis that P. gingivalis periodontal infection may cause cognitive impairment via age-dependent neuroinflammation was...

We examined the effect of excessive Internet use on the time–frequency characteristic of the electroencephalogram by wavelet transformed and non-negative matrix factorization (NMF). The event-related potentials (ERP) of normal subjects and excessive Internet users were acquired using the oddball paradigm experiment. We applied the wavelet transformed and event-related spectral perturbation to ERP...

Feature classification is one of the important aspects in brain-computer interfaces (BCI) system. It has been known that a higher precision can be achieved if use neutral networks in a proper way for feature classification. In this paper, three feature identification ways were introduced and discussed. In the experiment of left-right hand classification, the arithmetic of the small mean square difference...

The aim of this study was to confirm the character of EEG and the location in brain when a person was enjoying different rhythm music. It made the subjects excited when they enjoyed different rhythm music, the EEG signals are collected with Phoenix Digital EEG with 128 channels, and compared with the ones before the subjects enjoying the music. Obvious differences have been found between them. And...

The aim of this study is to confirm the character of EEG and the location in brain when a person is being excited. The subjects get excited with absorption of fixed quantity of coffee. EEG signals are collected with Phoenix Digital EEG with 128 channels, and compared with the ones before the subjects drink the coffee. Obvious differences have been found between them. The character of EEG is a wave...
