Small or micro hydro power generation is a promising renewable energy source that has received significant attention because of its capacity to generate green energy ranging from few watts up to hundreds of kilowatts. Small, low head hydropower plants are applicable in remote areas where grid extension is difficult due to geographical terrain. Micro hydro generators do not require the large cost of...
Deep brain stimulation of subthalamic nucleus (STN-DBS) became a standard therapeutic option in Parkinson's disease (PD), even though the underlying modulated network of STN-DBS is still poorly described. Probabilistic tractography and connectivity analysis as derived from diffusion tensor imaging (DTI) were performed together with modelling of implanted electrode positions and linked postoperative...
Voxel based morphometry (VBM) is an automated analysis technique which allows voxel-wise comparison of mainly grey-matter volumes between two magnetic resonance images (MRI). Two main analysis processes in VBM are possible. One is cross-sectional data analysis, where one group is compared with another to depict see the regions in the brain, which show changes in their grey-matter volume. Second is...
Essential tremor follows an autosomal dominant type of inheritance in the majority of patients, yet its genetic basis has not been identified. The age of onset in this tremor is bimodal, one in young age and another when they are old. The old onset is referred to as senile tremor in this study. The precise pathology is still not completely understood for both these tremors. We wanted to develop an...
The acceptor substrate promiscuity of YjiC, a UDP-glycosyltransferase from Bacillus licheniformis, was explored with seven different classes (flavonols, flavanols, flavones, flavanones, chalcone, stilbene, and isoflavonoids) of 23 flavonoid acceptors. For most of the polyphenols used in the reactions, the enzymatic bioconversion was significantly higher with the production of multiple glucosylated...
We first report evidence by using terahertz (THz) spectroscopy of plasmonic excitations in a topological insulator (TI) that was engineered in thin micro-ribbon arrays. Plasmons are due to Dirac quasi-particles of the two-dimensional electron gas which forms at the surface of TIs.
A fully integrated 0.18um CMOS Low Noise Amplifier (LNA) with Notch Filter for interference rejection at 5-6 GHz in UWB systems is presented. The notch filter comprises a series LC resonance circuit, which with a resistance cancelation approach yields excellent attenuating characteristics. The post layout simulation of this circuit is able to achieve more than 25 dB of attenuation at 5.6 GHz. The...
