This publication presents a new hybrid Gaussian processes approach to estimate gross primary production (GPP)—the amount of carbon plants fix through photosynthesis—at high spatial resolution using Sentinel-2 reflectance data. By combining physical knowledge with data-driven modelling, the method produces more accurate and spatially detailed GPP maps, particularly in complex forest and vegetation landscapes. The results highlight the approach’s strong potential for improving carbon cycle assessments and supporting climate- and ecosystem-related monitoring efforts.

This review highlights how in situ and operando spectroscopic and scattering techniques are advancing our understanding of reticular materials such as MOFs and COFs. By probing these porous frameworks under working conditions, researchers can track active sites, reaction intermediates, and structural dynamics during catalysis, gas adsorption, and photochemical processes. The article surveys recent progress across characterization methods, discusses how these insights inform synthesis and design, and points to opportunities for developing more efficient materials for energy and environmental applications.

Guidance for researchers and innovators in Near Neighbour Countries and Third/International Partner Countries. This publication explains how to get involved in COST Actions and what opportunities are available.

The COST corporate publication ‘Growing ideas through networks’ explains the COST Programme and COST Actions, including how they operate, who they are for, and how to propose or join an Action.

The book emerges from COST Action COREnet, a European research network initiated in 2021 that connects theory and practice in the field of migration and religious diversity. Over the course of several years, COREnet scholars from diverse disciplines and cultural contexts engaged in collaborative research, dialogical formats, and innovative methodologies to critically analyse how narratives influence migration experiences and to explore the role of religion and secular worldviews in these processes.

One of the most innovative aspects of the volume is its methodological emphasis on listening to the voices of migrants themselves. To facilitate this, the network developed and implemented the concept of “narrative cafés.” These dialogical spaces allowed migrants to share their personal stories in a supportive, interactive environment, thereby highlighting their lived experiences beyond abstract political or academic debates.

By bridging theoretical frameworks and practical concerns, Religious and Non-Religious Narratives on Migration offers scholars, policymakers, and practitioners critical tools for engaging migration in ways that are both academically rigorous and socially constructive.

The volume will be of particular interest to researchers in theology, sociology, philosophy, and education, as well as policymakers and organisations working in the fields of migration, integration, and interreligious dialogue.

In this paper, we experimentally demonstrate and analyze the performance of software-defined radio (SDR)-based hybrid optical wireless communication (OWC) links for indoor Internet-of-Things (IoT) networks. We propose all-optical hybrid visible light communication (VLC) and optical camera communication (OCC) using a single light emitting diode (LED) as a transmitter and photodiode (PD) and image sensor (IS) based receivers for simultaneous high-and low-speed data transmission. We present a testbed using an SDR platform, i.e., the ADALM-PLUTO, to transmit and receive high-and low-speed signals in the very-high frequency band and a media converter as part of an OWC link. We evaluate the performance of the proposed hybrid system employing a chip LED modulated with quadrature phase shift keying signal in terms of the bit error rate and the reception success rate Rrs. We show that the proposed scheme can provide an independent link performance, irrespective of the significant differences between the operating data rates of VLC and OCC links. The results show that for a link span of 1 m, we achieve (i) error-free detection for high-speed PD-based VLC; and (ii) 100 % Rrs at varying modulation frequencies for low-speed IS-based OCC.

This paper proposes a novel fingerprinting method by applying the controlled non-linearities of RF amplifiers in compression mode to generate robust signal signatures. By analyzing the distinct distortion patterns and harmonic content produced under compression, we define a signaling mechanism helping to generate a robust fingerprinting mechanism. Our approach presents an ability to generate confusion in eavesdroppers so ensuring high robustness and resilience against passive and active attacks. Numerical results demonstrate the consistency and robustness of the signal signatures. This method not only enhances security by integrating physical-layer properties, but may contribute to reduce the computational burden of traditional cryptographic techniques. Our findings indicate that using amplifier non-linearities for fingerprinting significantly improves the security and efficiency of wireless communication systems.

As 6G networks introduce increasingly diverse and complex applications, network slicing is a key enabling technology for partitioning network resources to meet these dynamic demands. However, efficiently managing and allocating these finite resources has become vital. This necessity drives the adoption of an open marketplace model. To address the business and technical complexities associated with such open marketplaces, this paper presents the demonstration of a non-fungible token (NFT)-enabled resource trading marketplace tailored for 6G network slicing. The proposed solution is implemented on an Ethereum-based blockchain system to assess its viability.

Internet of Things (IoT) technology has become ubiquitous with a broad spectrum of applications. This vast penetration entails formidable cyber-security for the stable operation of the associated systems. Most inexpensive IoT devices employ rudimentary cryptographic security mechanisms due to their resource-limited architecture. Radio frequency fingerprinting (RFF) is a physical layer security mechanism that leverages hardware impairments for authentication and device classification. To this end, its scope has been limited to academia owing to daunting challenges. In this work, an abridged overview of the state-of-the-art is provided, along with a summary of the challenges that hinder progress toward practical applications. The article culminates with a discussion on the intricacies of performance metrics in RFF and the direction for future research.
