MOTIVATION With increasing availability of temporal real-world networks, how to efficiently study these data? One can model a temporal network as a single aggregate static network, or as a series of time-specific snapshots, each being an aggregate static network over the corresponding time window. Then, one can use established methods for static analysis on(More)
Post array waveguides consist of dielectric or metallic cylinders for microwave around 4GHz were experimentally and numerically investigated. In the waveguide with dielectric cylinders, confinement of microwave is poor, when the post array was consisted from 1 row of cylinders. The confinement was improved as increase of rows of post array. In metallic(More)
This paper discusses multimodal affect detection from a fusion of facial expressions and interaction features derived from students' interactions with an educational game in the noisy real-world context of a computer-enabled classroom. Log data of students' interactions with the game and face videos from 133 students were recorded in a computer-enabled(More)
Y-shaped branches of post array waveguide consist of dielectric cylinders for microwave around 4GHz were experimentally and numerically investigated. In the waveguide with a pair of 1 layer of cylinders, confinement of microwave is poor at branching point and along with waveguides. The confinement was improved by increase of post wall up to 3 layers. These(More)
Since human aging is hard to study experimentally due to long lifespan and ethical constraints, current "ground truth" knowledge about human aging has mostly been <i>predicted</i> computationally or statistically by transferring the knowledge from well-studied model species via sequence homology or by studying human gene expression data. Since genes, i.e.,(More)
Measurement of cavity in two-dimensional square-lattice photonic crystal structure composed of metallic pillars was done to investigate its fundamental resonance characteristics. Implementation of the resonance based on another measurement of phase and wavelength along with the propagation axis could explain the behavior clearly.
Current "ground truth" knowledge about human aging has been obtained by transferring aging-related knowledge from well-studied model species via sequence homology or by studying human gene expression data. Since proteins function by interacting with each other, analyzing protein-protein interaction (PPI) networks in the context of aging is promising. Unlike(More)
Structural aspects of the environment frequently influence the taxonomic and functional diversity of associated ecological communities. Spartina alterniflora and Phragmites australis both are structure-forming species in salt marshes but reciprocal invaders. Epifaunal communities on invasive Phragmites on the east coast of North America are reduced relative(More)
Measurement of crank-shaped waveguide in two-dimensional square-lattice post array structure composed of aluminum pillars as well as ceramic pillars was done to investigate its fundamental transmission and reflection characteristics. Resonance in the crank by cavity structure composed of aluminum pillars was measured. To improve the resonant(More)
Measurement of cavity in two-dimensional square-lattice photonic crystal structure composed of metallic pillars was done to investigate its fundamental resonance characteristics. For consideration of confinement of the propagating electromagnetic field, the structure with dielectric pillars are also measured. Both of the results showed good agreement with(More)
