We integrate, for the first time in the literature, the following ingredients to deal with emerging dynamic spectrum management (DSM) problem in heterogeneous wireless sensors and actuators networks (WSANs), Internet of things (IoT) and Wi-Fi: (i) named-based routing to provide provenance and location-independent access to control plane; (ii) temporary storage of control data for efficient and cohesive control dissemination, as well as asynchronous communication between software-controllers and devices; (iii) contract-based control to improve trust-ability of actions; (iv) service-defined configuration of wireless devices, approximating their configurations to real services needs. The work is implemented using NovaGenesis architecture and a proof-of-concept is evaluated in a real scenario, demonstrating our approach to automate radio frequency channel optimization in Wi-Fi and IEEE 802.15.4 networks in the 2.4 GHz bands. An integrated cognitive radio system provides the dual-mode best channel indications for novel DSM services in NovaGenesis. By reconfiguring Wi-Fi/IoT devices to best channels, the proposed solution more than doubles the network throughput, when compared to the case of mutual interference. Therefore, environments equipped with the proposal provide enhanced performance to their users.

Aerial insects are exceptionally agile and precise owing to their small size and fast neuromotor control. They perform impressive acrobatic maneuvers when evading predators, recovering from wind gust, or landing on moving objects. Flapping-wing propulsion is advantageous for flight agility because it can generate large changes in instantaneous forces and torques.

Background: Appendicectomy is a common procedure in children. Regional anaesthesia helps reduce requirements for opioids and hospital stay and enhances recovery. Laparoscopic-assisted Transversus Abdominus Plane block (L-TAP) was shown to be efficient and potentially superior to port site infiltration (PSI); however, this was not previously studied in paediatric appendicitis.

Cryoanalgesia of the intercostal nerves has been demonstrated to reduce postoperative pain in these patients. The objective of this study was to understand how and how widely cryoanalgesia is used in pediatric patients undergoing funnel chest surgery in Spain.

Emissions from airport sources degrade air quality impacting community health. While some airports assess air pollution, others assess broader environmental effects, including CO emissions and noise. Utilising a transition management approach, this paper examines Australian airport practices and develops key sustainable strategies to reduce environmental impacts.

Background: Facial trauma repair requires precise reconstruction while preserving aesthetic units. Traditional local anesthesia can distort tissue planes and compromise surgical precision.
Methods: This prospective study evaluated landmark-based nerve blocks versus local infiltration for complex facial laceration repair in emergency settings from January 2022 through February 2023.
