Abstract Rotating two overlapping lattices relative to each other produces the well known moiré interference patterns and has surprisingly led strongly correlated superconductivity in twisted bilayer graphene. This seminal effect that is associated with electrons occupying flat dispersion bands stimulated a surge of activities classical wave physics such as acoustics explore equivalent scenario...

Abstract. Media psychology researchers seek to understand both why people choose certain media over others and how influence cognitive, emotional, social, psychological processes. A burgeoning body of literature has emerged in recent years describing selection effects as reciprocally linked dynamic processes, but research approaches empirically investigating them such have been sparse. In paral...

analyses and investigations on river flow behavior are major issues in design, operation and studies related to water engineering. thus, recently the application of chaos theory and new techniques, such as chaos theory, has been considered in hydrology and water resources due to relevant innovations and ability. this paper compares the performance of chaos theory with anfis model and discusses ...

  This study compared the use of interpersonal and mass media channels of communication among rural farmers in Kogi State, Nigeria. The specific objectives were to describe the socio economic characteristics of the farmers, determine the influence of socioeconomic characteristics on the usage of interpersonal and media channels, ascertain farmers’ level of awareness of interpersonal and media c...

in this paper, a finite element model is developed for the fully hydro-mechanical analysis of hydraulic fracturing in partially saturated porous media. the model is derived from the framework of generalized biot theory. the fracture propagation is governed by a cohesive fracture model. the flow within the fracture zone is modeled by the lubrication equation. the displacement of solid phase, and...

For the first time to our knowledge, we demonstrate the use of self-enhanced diffraction to optically restore weak dynamic volume holograms. This restoration process is achieved through the use of a novel beam-toggling scheme that significantly enhances the steady-state diffraction efficiency of volume index gratings stored in photorefractive media. Experiments demonstrating and confirming theo...

Research at the forefront, new fields for research, the cutting edge? Given this rather ambitious and possibly grandiose brief, I began by asking around among my colleagues for their views, I kept my ears open at the recent ICA in San Francisco, so as to listen out for the new ideas in the air before they reached the always-delayed publication stage, and I scanned recent issues of the media and...
