Optimizing Tensor Train Decomposition in DNNs for RISC-V Architectures Using Design Space Exploration and Compiler Optimizations
Theologos Anthimopoulos, Milad Kokhazadeh, Vasilios Kelefouras +2
Deep neural networks (DNNs) have become indispensable in many real-life applications like natural language processing, and autonomous systems. However, deploying DNNs on resource-c…
SORIS: A Self-Organized Reconfigurable Intelligent Surface Architecture for Wireless Communications
Evangelos Koutsonas, Alexandros-Apostolos A. Boulogeorgos, Stylianos E. Trevlakis +3
In this paper, a new reconfigurable intelligent surface (RIS) hardware architecture, called self-organized RIS (SORIS), is proposed. The architecture incorporates a microcontroller…
Reconstructing the Antikythera Mechanism s Central Front dial parts Division and Placement of the Zodiac Dial ring
Aristeidis Voulgaris, Christophoros Mouratidis, Andreas Vossinakis
In this paper we analyze, discuss and present the design of the Antikythera Mechanism s central front parts. Based on the aligned and of same scale visual images of Fragment C fron…
High-Fidelity Coherent-One-Way QKD Simulation Framework for 6G Networks: Bridging Theory and Reality
Aitor Brazaola-Vicario, Vasileios Kouvakis, Stylianos E. Trevlakis +4
Quantum key distribution (QKD) has been emerged as a promising solution for guaranteeing information-theoretic security. Inspired by this, a great amount of research effort has bee…
Scale-Dependent Dynamic Alignment in MHD Turbulence: Insights into Intermittency, Compressibility, and Imbalance Effects
Nikos Sioulas, Marco Velli, Alfred Mallet +7
Scale-Dependent Dynamic Alignment (SDDA) in Elsässer field fluctuations is theorized to suppress nonlinearities and modulate the energy spectrum. Limited empirical evidence exists…
Higher-Order Analysis of Three-Dimensional Anisotropy in Imbalanced Alfvénic Turbulence
Nikos Sioulas, Themistocles Zikopoulos, Chen Shi +10
We analyze in-situ observations of imbalanced solar wind turbulence to evaluate MHD turbulence models grounded in "Critical Balance" (CB) and "Scale-Dependent Dynamic Alignment" (S…
Dermatologist-like explainable AI enhances trust and confidence in diagnosing melanoma
Tirtha Chanda, Katja Hauser, Sarah Hobelsberger +32
Although artificial intelligence (AI) systems have been shown to improve the accuracy of initial melanoma diagnosis, the lack of transparency in how these systems identify melanoma…
Stabilizing Spherical Energy Shells with Angular Momentum in Gravitational Backgrounds
I. Antoniou, D. Kazanas, D. Papadopoulos +1
Spherical energy shells in General Relativity tend to collapse due to gravitational effects and/or due to tension effects. Shell stabilization may be achieved by modifying the grav…
Generic non-extendability and total unboundedness in function spaces
V. Nestoridis, A. G. Siskakis, A. Stavrianidi +1
For a function space $X(\OO)$ satisfying weak assumptions we prove that the generic function in $X(\OO)$ is totally unbounded, hence non-extendable. We provide several examples of…
Argumentation Mining: Exploiting Multiple Sources and Background Knowledge
Anastasios Lytos, Thomas Lagkas, Panagiotis Sarigiannidis +1
The field of Argumentation Mining has arisen from the need of determining the underlying causes from an expressed opinion and the urgency to develop the established fields of Opini…
Eccentricity generation in hierarchical triple systems: the planetary regime
Nikolaos Georgakarakos
In previous papers, we developed a technique for estimating the inner eccentricity in hierarchical triple systems, with the inner orbit being initially circular. We considered syst…
Charge separation in organic photovoltaic cells
Paraskevas Giazitzidis, Panos Argyrakis, Juan Bisquert +1
We consider a simple model for the geminate electron-hole separation process in organic photovoltaic cells, in order to illustrate the influence of dimensionality of conducting cha…
Spectroscopic Coronal Observations during the Total Solar Eclipse of 11 July 2010
A. G. Voulgaris, P. S. Gaintatzis, J. H. Seiradakis +2
The flash spectrum of the solar chromosphere and corona was measured with a slitless spectrograph before, after, and during the totality of the solar eclipse, of 11 July 2010, at E…
