A Tactic for Architectural Exploitation of Indoor Small Cells for Dynamic Spectrum Sharing in 5G

open access: yesIEEE Access, 2020
This paper presents a tactic to realize numerous in-building small cell base station (SBS) architectures for dynamic spectrum sharing by varying the number of physical transceivers as well as the number, amount, and characteristics of operating spectrums

Blockchain-enabled dynamic credible spectrum sharing in 6G networks [PDF]

open access: yesBlockchain
Dynamic spectrum sharing (DSS) is essential for 6G networks, yet existing blockchain-based DSS solutions often lack an integrated approach that simultaneously addresses trust, allocation fairness, and system scalability.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Evolution Toward Data-Driven Spectrum Sharing: Opportunities and Challenges

open access: yesIEEE Access, 2023
As the demand for wireless services continues to grow, the need for efficient and effective management of the radio frequency (RF) spectrum becomes increasingly important. A spectrum management approach based on data analysis and interpretation i.e. data-

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Over-Booking Approach for Dynamic Spectrum Management [PDF]

open access: yes, 2011
An over-booking based dynamic spectrum management (DSM) scheme is conceived for improving the attainable spectral efficiency. All secondary users (SU) will be categorized into different classes and they borrow spectral resources from the primary users ...

Spectrum Hole Geolocation for Database-Driven IoT-Enabled Dynamic Spectrum Access

open access: yesIEEE Access
The effective realization of dynamic spectrum access (DSA) subsumes that, when a secondary terminal seeks a vacant band, the geolocation of the candidate spectrum hole coincides with the position of the terminal.

Dynamic spectrum access and sharing through actor-critic deep reinforcement learning

open access: yesEURASIP Journal on Wireless Communications and Networking, 2022
When primary users of the spectrum use frequency channels intermittently, secondary users can selectively transmit without interfering with the primary users.

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

Coopetition spectrum trading in cognitive radio networks [PDF]

open access: yes, 2013
Spectrum trading is a promising method to improve spectrum usage efficiency. Several issues must be addressed, however, to enable spectrum trading that goes beyond conservative trading idle bands and achieve cooperation between primary and secondary ...
