Designing a sub-wavelength array to change the direction of the radiation wave to a desired angle using variable Huygens surfaces [PDF]
AUT Journal of Electrical EngineeringSince Huygens structures with phase shift lead to beam rotation, this manuscript discusses a phase shifter structure for the Huygens surface based on Tapered Slot Transition in the frequency range of 9.95-10.2 GHz using varactor diodes.

Bistable Mechanisms 3D Printing for Mechanically Programmable Vibration Control
Advanced Engineering Materials, EarlyView.This work introduces a 3D‐printed bistable mechanism integrated into tuned mass dampers (TMDs) for mechanically adaptive passive vibration suppression. Through optimized geometry, the bistable design provides adaptable vibration reduction across a broad range of scenarios, achieving effective vibration mitigation without complex controls or external ...

The Slot in the System: An empirical case study of the entrenchment of a construct
Lexis: Journal in English LexicologyIn Construction Grammar, many units are depicted as semi-schematic objects, with a fixed part and a slot to be filled by another language unit, leading to the utterance of a construct.

Advanced Functional Materials, EarlyView.Biofabrication aims at providing innovative technologies and tools for the fabrication of tissue‐like constructs for tissue engineering and regenerative medicine applications. By integrating multiple biofabrication technologies, such as 3D (bio) printing with fiber fabrication methods, it would be more realistic to reconstruct native tissue's ...

The sequence and productivity of Setswana verbal suffixes
Stellenbosch Papers in Linguistics Plus, 2014 Setswana is an agglutinative language with a rich verbal morphology, allowing for an elaborate system of verbal inflection. Until now, research on Setswana verbal morphology has largely been based on qualitative methods.

Active Frequency Selective Surface With Wide Reconfigurable Passband
IEEE Access, 2019 This paper presents an active frequency selective surface (AFSS) with a wide reconfigurable passband. The tuning mechanism was investigated with an equivalent circuit which consists of a parallel L-C resonant circuit and a series L-C resonant circuit.

Advanced Functional Materials, EarlyView.The versatile precursor‐assisted soft sphere close packing during slot‐die coating is investigated with in situ X‐ray scattering. The soft crystallization pathways towards a close packing involve multistep structural transitions such as surface nucleation, in‐plane, and out‐of‐plane crystallization.
