Parkinson’s disease is neurodegenerative in nature and associated with characteristic movement disorders, such as hand tremor. Wireless accelerometer applications may advance the quality of care for Parkinson’s disease patients. The acceleration waveform of the respective hand tremor can be recorded and stored for postprocessing and progressive status tracking. A wireless accelerometer configur...

We present ice velocities observed with global positioning systems and TerraSAR-X/TanDEM-X in a land-terminating region of the southwest Greenland ice sheet (GrIS) during the melt year 2012–2013, to examine the spatial pattern of seasonal and annual ice motion. We find that while spatial variability in the configuration of the subglacial drainage system controls ice motion at short timescales, ...

Disaccharides tagged with p-aminobenzoic acid (ABA) were separated by capillary electrophoresis (CE) and analyzed on-line with negative ion electrospray ionization tandem mass spectrometry (ESI/MS/MS). The formation of glycosylamine instead of reductive amination was selected as the derivatization reaction. In negative ion ESI, the glycosylamine approach provides more information on linkage and...

The flow around two tandem circular cylinders leads to significant lift fluctuation in the downstream cylinder owing periodic vortex shedding. To address such research issues, we present herein a numerical study that uses deep reinforcement learning perform active control (AFC) on with low Reynolds number of 100, where actuator causes rotation cylinder. First, center spacing ratio L* varies fro...

To elucidate the wind-direction dependence of rotor performance in closely spaced vertical-axis wind turbines, wind-tunnel experiments were performed at a uniform velocity. In experiments, pair/trio three-dimensional printed model turbines with diameter D = 50 mm was used. The systematically by applying incremental adjustments to gap g and rotational direction each changing direction. For tande...

Conversion of unsaturated fatty acids, FAMEs or triglycerides into the corresponding cyclic organic carbonates involves two reaction steps—double-bond epoxidation and CO2 insertion epoxide—that are generally conducted separately. We describe an assisted-tandem catalytic protocol able to carry out carbonation methyl oleate in one-pot without isolating epoxide intermediate. Methyl carbonate was o...

In reality all the engineering products are likely to deviate from their expected performance due to the presence of variations. The variations can cause any product optimization to easily fall into sub-optimal regime. In present adopted methodology, the robust design optimization (RDO) of the objective function makes performance insensitive to the variations/uncertainties. A hybrid optimizatio...

Various studies of whole-genome duplication (WGD) have been done on eukaryotic genomes, and WGD as well as gene duplication is being thought to be one of the important processes in genome evolution for some eukaryotic lineages such as yeast, fishes, and vertebrates [4]. As for prokaryotic species, however, only a few studies on Escherichia coli [2, 5] and Anabaena [3] have been reported. Furthe...
