Ultrahigh energy cosmic ray air showers probe particle physics at energies beyond the reach of accelerators. Here we introduce a new method to test hadronic interaction models without relying on the absolute energy calibration, and apply it to events with primary energy 6–16 EeV (), whose longitudinal development and lateral distribution were simultaneously measured by the Pierre Auger Observatory. The average hadronic shower is () times larger than predicted using the leading LHC-tuned models EPOS-LHC (QGSJetII-04), with a corresponding excess of muons.

Cloud Computing and Internet of Things (IoT) are currently two of the most popular ICT paradigms that are expected to shape the next era of computing. The convergence between cloud computing and IoT has become a hot topic over the last few years because of the benefits that IoT could have from the distributed nature of cloud computing infrastructures. This paper proposes a new platform for using cloud computing capacities for provision and support of ubiquitous connectivity and real-time applications and services for smart cities' needs. We present a framework for data procured from highly distributed, heterogeneous, decentralized, real and virtual devices (sensors, actuators, smart devices) that can be automatically managed, analyzed and controlled by distributed cloud-based services.

Ion MarghescuRazvan CraciunescuOctavian FratuWith the decrease in the cost and size of drones in recent years, their number has also increased exponentially. As such, the concerns regarding security aspects that are raised by their presence are also becoming more serious. The necessity of designing and implementing systems that are able to detect and provide defense actions against such threats has become apparent. In this paper, we perform a survey regarding the different drone detection and defense systems that were proposed in the literature, based on different types of methods (i.e., radio frequency (RF), acoustical, optical, radar, etc.), with an emphasis on RF-based systems implemented using software-defined radio (SDR) platforms. We have followed the preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines in order to provide a concise and thorough presentation of the current status of the subject. In the final part, we also describe our own solution that was designed and implemented in the framework of the DronEnd research project. The DronEnd system is based on RF methods and uses SDR platforms as the main hardware elements.

The transition to 6th Generation (6G) cellular networks offers significant improvements over 5th Generation (5G), enhancing data transfer, reducing latency, and improving network reliability. Advanced Multiple-Input Multiple-Output (MIMO) technology in 6G boosts network efficiency, particularly benefiting Ultra-Reliable Low-Latency Communications (URLLC). This paper reviews literature on resource management in the Internet of Things (IoT) within the 6G context. We categorize the study into four segments: network-aware resource management, dynamic resource allocation, predictive resource distribution based on traffic and architecture, and energy-centric resource allocation considering IoT device mobility and location. We provide a detailed perspective on current research and highlight future research avenues. Key contributions include a comparative study of IoT resource management techniques, an overview of resource management across LTE, 5G, and 6G networks, insights into applications like Intelligent Transportation Systems (ITS), Industrial IoT (IIoT), and Mobile CrowdSensing (MCS), and an emphasis on upcoming challenges. We emphasize the crucial role of efficient resource management in IoT, particularly in the 6G landscape.

About Me
Octavian Fratu received a Ph.D. degree in Electronics and Telecommunications from the University "Politehnica" of Bucharest, Romania, in 1997. He achieved the postdoctoral stage as a senior researcher in 3rd-generation mobile communication systems, based on a research contract between CNET-France, ENS de Cachan, France, and Universite Marne la Vallee, France. He is currently a professor in the Electronics, Telecommunications, and Information Theory Faculty. His research interests include digital mobile communications, radio data transmissions, mobile communications, and wireless sensor networks. His publications include more than 200 papers published in national or international scientific journals or presented at international conferences. He participated as director or collaborator in many international research projects such as Reconfigurable Interoperability of Wireless Communications Systems (RIWCoS)" (NATO Science for Peace research project, 2007–2010), REDICT—Regional Economic Development by ICT/New Media Clusters" (FP7 CSA Project, 2008–2009), "eWALL for Active Long Living-eWALL" (FP7 IP Project, 2013–2016), and others. Currently, he is leading the national-funded "Integrated Software Platform for Mobile Malware Analysis (ToR-SIM)" No. 5Sol/2017 project and the communication subproject of the MultiMonD2 complex project (No. 33PCCDI/2018).
