Metasurface-based antennas show variable beam-patterns in response to the time width of electromagnetic pulses. This concept advances the design of antennas and wireless communication environments by using the pulse width as a new degree of freedom.

We present a new concept of metasurface filters to preferentially extract pulsed waveforms at a constant frequency from a complex superimposed input signal. This filtering capability is realized using circuit-based metasurfaces, denoted waveform-sele

XB130, a novel adaptor protein, promotes cell growth by controlling expression of many related genes. MicroRNAs (miRNAs), which are frequently mis-expressed in cancer cells, regulate expression of targeted genes. In this present study, we aimed to ex

Epithelial-mesenchymal transition (EMT) is an important mechanism in carcinogenesis. To determine the mechanisms that are involved in the regulation of EMT, it is crucial to develop new biomarkers and therapeutic targets towards cancers. In this stud

This work examined the effect of changing molding conditions on the physical aging of polystyrene injection moldings. First, we investigated the relationship between the molecular orientation and the molding conditions. The molecular orientation near
