The Post-Electromagnetic Era: A Vision for Wireless Communication Beyond 6G
Electromagnetic (EM) communication is nearing its physical and thermodynamic limits, where further performance gains through spectrum optimization alone have become increasingly unsustainable. Finite bandwidth, propagation loss at higher frequencies, and the inherent trade-offs between energy and information constrain the scalability of 6G and beyond systems. These limitations drive the search for alternative mechanisms for information transfer beyond conventional EM propagation. This work intr…

Higher-order epitaxy: A pathway to suppressing structural instability and emergent superconductivity
Molecular beam epitaxy enables the growth of thin film materials with novel properties and functionalities. Typically, the lattice constants of films and substrates are designed to match to minimise disorders and strains. However, significant lattice mismatches can result in higher-order epitaxy, where commensurate growth occurs with a period defined by integer multiples of the lattice constants. Despite its potential, higher-order epitaxy is rarely used to enhance material properties or induce…

French Court of Auditors publishes report on state-owned nuclear power company EDF. Already facing €53 billion in debt, it will have to invest €460 billion in the coming 15 years: €90 billion in keeping its existing nuclear power plants running, €110 billion in new nuclear for France, €100 billion in grids. Much higher power prices and reducing international investments will be needed.

Le modèle économique d’Électricité de France (EDF)
Issue d’un Épic (Établissement public à caractère commercial) en situation de monopole sur le territoire français, de la production à la fourniture d’électricité, en passant par le transport et la distribution, EDF et ses filiales, exercent aujourd’hui leur activité de façon diversifiée dans le domaine de l’énergie et dans de nombreux pays. La Cour, sollicitée par la commission des finances de l’Assemblée nationale, publie un rapport sur son modèle économique et analys…

Asymptotic Higher Spin Symmetries: Noether Realization & Algebraic Structure in Einstein-Yang-Mills Theory
This thesis deals with the phase space realization of asymptotic higher spin symmetries, in 4d asymptotically flat spacetimes. In the gravitational case for instance, these symmetries generalize the BMS algebra to include an infinite tower of symmetry generators constructed from tensors on the sphere of arbitrary high rank $s$. Building on a first series of results on their canonical representation, we develop the necessary framework to define Noether charges for all degrees $s$. Importantly,…

Graphical Perception of Icon Arrays versus Bar Charts for Value Comparisons in Health Risk Communication
Visualizations support critical decision making in domains like health risk communication. This is particularly important for those at higher health risks and their care providers, allowing for better risk interpretation which may lead to more informed decisions. However, the kinds of visualizations used to represent data may impart biases that influence data interpretation and decision making. Both continuous representations using bar charts and discrete representations using icon arrays are p…

Determinants of Latin American students academic resilience-Insights based on PISA 2022 using an explainable machine learning approach
The learning crisis in the Latin American region (i.e., higher rates of students not reaching basic competencies at secondary level) is worrying, particularly post-pandemic given the stronger role of inequality behind achievement. Within this scenario, the concept of student academic resilience (SAR), students who despite coming from disadvantaged backgrounds reach good performance levels, and an analysis of its determinants, are policy relevant. In this paper, using advancements on explainable…

A Study of Neural Polar Decoders for Communication
In this paper, we adapt and analyze Neural Polar Decoders (NPDs) for end-to-end communication systems. While prior work demonstrated the effectiveness of NPDs on synthetic channels, this study extends the NPD to real-world communication systems. The NPD was adapted to complete OFDM and single-carrier communication systems. To satisfy practical system requirements, the NPD is extended to support any code length via rate matching, higher-order modulations, and robustness across diverse channel co…

Low Complexity Weight Flexible Decoding Schemes of Linear Block Code for 6G xURLLC
Low complexity error correction code is a key enabler for next generation ultra-reliable low-latency communications (xURLLC) in six generation (6G). Against this background, this paper proposes a decoding scheme for linear block code by leveraging certain interesting properties of dual codewords. It is found that dual codewords with flexible weights can provide useful decoding information for the locations and magnitudes of error bits, which yielding higher reliability performance. In addition,…

Neural Network-Based Single-Carrier Joint Communication and Sensing: Loss Design, Constellation Shaping and Precoding
We investigate the impact of higher-order modulation formats on the sensing performance of single-carrier joint communication and sensing (JCAS) systems. Several separate components such as a beamformer, a modulator, a target detector, an angle of arrival (AoA) estimator and a communication demapper are implemented as trainable neural networks (NNs). We compare geometrically shaped modulation formats to a classical quadrature amplitude modulation (QAM) scheme. We assess the influence of multi-s…

Wideband Integrated Sensing and Communications: Spectral Efficiency and Signaling Design
In integrated sensing and communications (ISAC), a distinguishing feature of 6G wireless networks, the main challenge lies in integrating the two distinct functions of sensing and communication within the same waveform. In this paper, the ISAC waveform synthesis is studied in the wideband regime, since a large bandwidth can simplify the analysis and is justified by the employment of millimeter wave or higher frequency band. Standard orthogonal frequency division multiplexing (OFDM) signaling is…
