This paper considers a reconfigurable intelligent surface (RIS) aided orthogonal frequency division multiplexing (OFDM) relaying system, and investigates the joint design of RIS passive beamforming subcarrier matching under two cases, where Case-I ignores source-RIS-destination signal, while Case-II explores this signal for rate enhancement. We formulate mixed-integer nonlinear programming (MIN...

We present an approach for obtaining a molecular orbital picture of the first dipole hyperpolarizability (β) from correlated many-body electronic structure methods. Ab initio calculations β rely on quadratic response theory, which recasts sum-over-all-states expression into closed-form by calculating handful first- and second-order states; resonantly enhanced β, damped theory is used. These sta...

Recent studies in Second Language Acquisition (SLA) have shown that there is an apparent relationship between teachers' beliefs and their classroom practices of oral corrective feedback second language teaching. Even though many experimental show it beneficial for acquisition, relatively little research has explored the teachers terms feedback. This descriptive study aims to examine stated abou...

In part I, we considered the application of method fundamental solutions (MFS) for solving numerically Brinkman fluid flow in unbounded porous medium outside obstacles known or unknown shapes. this companion paper consider corresponding interior problem a bounded which contains an rigid inclusion $$D \subset \Omega $$ . The D is to be identified by pair Cauchy data represented velocity and trac...

This article recasts the debate over employment status of gig economy workers as a question about power municipal governance. Gig employers are challenging urban regulatory regimes through their disavowal an relationship and refusal to obtain taxi licenses. As recent literature argues, there has been resurgence driven by labor-antipoverty coalition. One might view economy’s independent contract...

Hyperspectral image (HSI) clustering is a challenging task due to the high complexity of HSI data. Subspace has been proven be powerful for exploiting intrinsic relationship between data points. Despite impressive performance in clustering, traditional subspace methods often ignore inherent structural information among In this article, we revisit with graph convolution and present novel framewo...

This conversation analysis study investigates facilitators’ simultaneous use of speech and aided means in instructional interaction with children complex communication needs (CCN), who an everyday setting. The participants were severe impairments their partners. focused on turns immediately following by the children, within so-called retro-sequences. Retro-sequences found interactions involving...
