Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy
Advanced Quantum Technologies, EarlyView.A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.

Parametric Excitation of a Ferrimagnetic Sphere Resonator
Advanced Quantum Technologies, EarlyView.The hypothesis that disentanglement spontaneously occurs in quantum systems is experimentally tested using a ferromagnetic resonator. Predictions derived from the hypothesis, and from an alternative theoretical model, are compared with the measured response of the resonator to an externally applied driving.

International Journal of Satellite Communications and Networking, EarlyView.ABSTRACT As non‐terrestrial networks (NTNs) become integral to future 6G systems, ensuring seamless connectivity and service continuity over low Earth orbit (LEO) satellite constellations is essential. This work investigates the impact of open radio access network (RAN) functional splits on handover performance in NTNs, focusing on minimizing service ...

Cluster-based DBMS Management Tool with High-Availability [PDF]
Journal of Systemics, Cybernetics and Informatics, 2005 A management tool which is needed for monitoring and managing cluster-based DBMSs has been little studied. So, we design and implement a cluster-based DBMS management tool with high-availability that monitors the status of nodes in a cluster system as ...

160 GHz Schottky Diodes from Solution‐Processed IGZO
Small, EarlyView.A simple, scalable method for contact engineering of planar asymmetric nanogap electrodes enables the development of Schottky diodes with a cut‐off frequency of 160 GHz. Applying these diodes to radio‐frequency rectifying circuits yields output voltages in the range of 0.3–0.74 volts.

A Validation Approach for Ontology-Based Real-time DBMS
International Journal of Computational Intelligence Systems, 2019 Real-time DBMS (DataBase Management Systems) are an appropriate storage system under real-time constraints. However real-time DBMS do not implement inference or reasoning mechanisms.
