Frequency vs. Association for Constraint Selection in Usage-Based Construction Grammar [PDF]

open access: yes, 2019
A usage-based Construction Grammar (CxG) posits that slot-constraints generalize from common exemplar constructions. But what is the best model of constraint generalization?

Multi-word units (and tokenization more generally): a multi-dimensional and largely information-theoretic approach

open access: yesLexis: Journal in English Lexicology, 2022
It has been argued that most of corpus linguistics involves one of four fundamental methods: frequency lists, dispersion, collocation, and concordancing. All these presuppose (if only implicitly) the definition of a unit: the element whose frequency in a

In-Band Radar Cross Section Reduction of Slot Array Antenna

open access: yesIEEE Access, 2018
A slot array antenna is proposed for both in-band and out-of-band radar cross section (RCS) reduction. The presented slot array antenna is covered by the superstrate consisting of a polarization rotation reflective surface (PRRS).

Analytical Model of a Single Link of Elastic Optical Networks

open access: yesIEEE Access, 2022
This article discusses and evaluates a model of resources to which multiservice traffic is offered. The initial assumption for the model is that calls of particular traffic classes are always serviced in neighboring allocation units of the resources ...

Transmitting-absorbing material based on resistive metasurface

open access: yesAIP Advances, 2018
We theoretically and experimentally studied a transmitting-absorbing material that had transmission window within the absorption band. The material had a sandwich structure comprised of a resistive metasurface, a dielectric substrate and a metallic slot ...

Low-noise 1 THz niobium superconducting tunnel junction mixer with a normal metal tuning circuit [PDF]

open access: yes, 1996
We describe a 1 THz quasioptical SIS mixer which uses a twin-slot antenna, an antireflection-coated silicon hyperhemispherical lens, Nb/Al-oxide/Nb tunnel junctions, and an aluminum normal-metal tuning circuit in a two-junction configuration.

A Multi-Service Model of Resources With the Neighboring Choice of Allocation Units

open access: yesIEEE Access, 2021
This article discusses a discretized model of resources to which a mixture of multi-service traffic streams is offered. In the model the connections of individual traffic classes that require a large number of allocation units are always executed using ...

Implementation of Magnetoelectric Dipoles in Metasurfaces for 5G Applications

open access: yesIEEE Open Journal of Antennas and Propagation, 2022
The well-known magnetoelectric dipole (ME-dipole) has huge adoption in antenna designs. In this paper, we manage to implement ME-dipoles in metasurfaces.
