First insights into satellitomes of Neuroptera and new evidence for absence of canonical insect telomere revealed through cytogenomics approach
Repetitive DNA is a major component of eukaryotic genomes, playing structural, and evolutionary roles. However, in Neuroptera,
its characterization remains unexplored. To address this, we analyzed the satellitomes of two Chrysopini (Chrysopidae)
species using cytogenomic tools, also investigating telomeric and ribosomal DNA (rDNA). The canonical insect telomeric motif
was absent, and rDNA clusters showed variation compared to other neuropterans, despite karyotype stasis (2n = 12, XY).
Satellite DNA (satDNA) abundance varied between Ceraeochrysa cincta and Chrysopa pallens, representing a minor fraction of
their repetitive DNA content. Notably, no satDNA sequences were shared between species, suggesting a rapid turnover. Exceptionally,
the second-most abundant satDNA in each species showed low sequence similarity and a putative common origin. A
relationship between satDNAs and transposable elements was also observed. Chromosome mapping revealed that abundant
satDNAs accumulated in euchromatin, providing insights into their genomic distribution. These findings enhance our understanding
of satDNA organization in Neuroptera, offering a foundation for future genome assembly efforts and evolutionary
studies in these insects

La imagen de Francia en las novelas de guerra de Vicente Blasco Ibáñez
RESUMEN EN CASTELLANO
Esta tesis doctoral es un estudio de investigación documental y analítica centrado en la aplicación de un modelo teórico original de Imagología a los textos ficcionales del autor referidos a la Primera Guerra Mundial. La investigación se articula en dos secciones diferenciadas. La primera aborda la teoría de la Literatura Comparada, ofreciendo una aproximación crítica a los estudios imagológicos y la formulación de un modelo teórico propio. La segunda examina la configuración de la imagen de Francia en la narrativa
bélica de Vicente Blasco Ibáñez, evaluando su representación dentro del contexto literario de la Gran Guerra.
Esta investigación interdisciplinar demuestra que la imagen de Francia en la narrativa bélica de Blasco Ibáñez funciona como eje configurador de la representación de la alteridad y como dispositivo crítico para comprender la interacción entre literatura, ideología y propaganda durante la Primera Guerra Mundial.
RESUMEN EN INGLÉS (
This doctoral dissertation is a documentary and analytical research study focused on applying an original imagological theoretical model to the author’s fictional texts on the First World War. The investigation is organized into two distinct sections. The first addresses Comparative Literature theory, offering a critical approach to imagological studies and the formulation of an original theoretical model. The second examines the construction of France’s image in Vicente Blasco Ibáñez’s war narratives, assessing
its representation within the literary context of the Great War. This interdisciplinary study shows that the image of France in Blasco Ibáñez’s war narrative functions both as the structuring axis of the representation of otherness and as a critical device for understanding the interplay among literature, ideology, and propaganda during the First World War
Neural networks and sliding modes in controlled uncertain synchronous motor systems "
A new robust motion tracking control design framework for uncertain synchronous motors
based on differential flatness, artificial neural networks, sliding modes and swarm intelligence, is proposed.
Robustness with respect to significant dynamic generalized uncertainty is proved. Knowledge of system
parameters and variable load torque are unnecessary. Dependence on mathematical modeling based on
physics is reduced. The presented control design approach is extended for a wide class of highly uncertain
and multi-input multi-output, nonlinear flat dynamic systems. Incorporation of observer algorithms for
accurate real-time disturbance estimation is not required. The introduced robust flat output-feedback control
design framework considers radial basis function and B-spline artificial neural networks to dynamically
tune in real-time sliding mode parameters. In this fashion, active attenuation of chattering is achieved from
a dynamic artificial intelligence control design perspective. Reliable control performance under exogenous
disturbances and endogenous uncertainty is demonstrated. A key insight is that B-splines networks offer
fast and localized adaptation with lower computational cost compared to traditional radial basis function
networks, making them more suitable for embedded real-time applications. Particle swarm optimization
is employed to optimize initial neural weights. The control scheme offers a scalable and efficient solution
suitable for embedded real-time applications, as demonstrated through various operating scenarios involving
nonlinear disturbances, load torque variations, and parametric uncertainty. The findings reveal the robust
performance of the proposed synchronous motor system control strategy for the efficient tracking of
smooth speed reference trajectories in presence of a wide spectrum of dynamic uncertainties. Moreover,
numerical results confirm the superiority of the proposed robust adaptive neural-network trajectory tracking
control framework for highly uncertain operating environments over previous model-based design studies.
Efficiency, robustness and uncertain system stability are guaranteed from the introduced dynamic artificial
intelligence control design perspective
Sustainable metaheuristic-based planning of rural medium-voltage grids: A comparative study of Spanning and Steiner tree topologies for cost-efficient electrification of rural medium-voltage grids: A comparative study of Spanning and Steiner tree topologies for cost-efficient electrification
This paper presents a heuristic methodology for the optimal expansion of unbalanced three-phase distribution systems in rural areas, simultaneously addressing feeder routing and conductor sizing to minimize the total annualized cost—defined as the sum of investments in conductors and operational energy losses. The planning strategy explores two radial topological models: the Minimum Spanning Tree (MST) and the Steiner Tree (ST). The latter incorporates auxiliary nodes to reduce the total line length. For each topology, an initial conductor sizing is performed based on three-phase power flow calculations using Broyden’s method, capturing the unbalanced nature of the rural networks. These initial solutions are refined via four metaheuristic algorithms—the Chu–Beasley Genetic Algorithm (CBGA), Particle Swarm Optimization (PSO), the Sine–Cosine Algorithm (SCA), and the Grey Wolf Optimizer (GWO)—under a master–slave optimization framework. Numerical experiments on 15-, 25- and 50-node rural test systems show that the ST combined with GWO consistently achieves the lowest total costs—reducing expenditures by up to 70.63% compared to MST configurations—and exhibits superior robustness across all performance metrics, including best-, average-, and worst-case solutions, as well as standard deviation. Beyond its technical contributions, the proposed methodology supports the United Nations Sustainable Development Goals by promoting universal energy access (SDG 7), fostering cost-effective rural infrastructure (SDG 9), and contributing to reductions in urban–rural inequalities in electricity access (SDG 10). All simulations were implemented in MATLAB 2024a, demonstrating the practical viability and scalability of the method for planning rural distribution networks under unbalanced load conditions
Integrating the strategic response of parking lots in active distribution networks: An equilibrium approach
The increasing penetration of electric vehicles will be accompanied for a wide deployment of charging infrastructures. Large charging demand brings formidable challenges to existing power networks, driving them near to their operational limits. In this regard, it becomes pivotal developing novel energy management strategies for active distribution networks that take into account the strategic behaviour of parking lots. This paper focuses on this issue, developing a novel energy management tool for distribution networks encompassing distributed generators and parking lots. The new proposal casts as a tri-level game equilibrium framework where the profit maximization of lots is implicitly considered, thus ensuring that network-level decisions do not detract the profit of parking owners. The original tri-level model is reduced into a tractable single-level mixed-integer-linear programming by combining equivalent primal-dual and first-order optimality conditions of the distribution network and parking operational models. This way, the model can be solved using off-the-shelf solvers, with superiority against other approaches like metaheuristics. The developed model is validated in well-known 33-, and 85-bus radial distribution systems. Results show that, even under unfavourable conditions with limited distributed generation, charging demand is maximized, thus preserving the interests of parking owners. Moreover, the model is further validated through a number of simulations, showing its effectiveness. Finally, it is demonstrated that the developed tool scales well with the size of the system, easing its implementation in real-life applications.Marcos Tostado-Véliz and Francisco Jurado acknowledge to the Spanish Ministry of Science and Innovation, under the research Project “Development of power-flow models for microgrid clusters” PID2021-123633OB-C31, Ministry of Science and Innovation, Knowledge Generation Projects 2021, Spain.
