The modern artificial intelligence techniques show the outstanding performances in the field of Non-Intrusive Load Monitoring (NILM). However, the problem related to the identification of a large number of appliances working simultaneously is underestimated. One of the reasons is the absence of a specific data. In this research we propose the Synthesizer of Normalized Signatures (SNS) algorithm to simulate the aggregated consumption with up to 10 concurrent loads. The results show that the synthetic data provides the models with at least as a powerful identification accuracy as the real-world measurements. We have developed the neural architecture named Concurrent Loads Disaggregator (COLD) which is relatively simple and easy to understand in comparison to the previous approaches. Our model allows identifying from 1 to 10 appliances working simultaneously with mean F1-score 78.95%.

High-quality sleep is critical for children’s and adolescents’ development and health. Despite the high prevalence of sleep disorders in this population, few polysomnography devices have tested specifically for pediatric use. We evaluated the Dormotech device, a novel sleep monitoring system designed for both clinical and home-based sleep studies, against gold standard polysomnographic equipment. Twenty-six children (mean age = 11.0 years, 50% female, mean body mass index 26.0 kg/m2) underwent simultaneous sleep studies with the novel device and gold-standard polysomnography in a sleep clinic. Data were manually scored following recommended guidelines. The primary outcome was apnea-hypopnea index (AHI) and its corresponding severity classification level (i.e. normal, mild, moderate, severe). Secondary endpoints included other standard polysomnography (PSG) parameters. The mean AHI measured by the novel device was 5.6 ± 15.3 events/h (mean ± standard deviation) while it was 5.2 ± 13.8 events/h from the gold standard PSG (p = 0.95, t-test). AHI severity classification showed excellent inter-test agreement (Cohen’s kappa = 0.87). Secondary endpoints demonstrated high correlation between devices, with no statistically significant differences in simultaneously recorded sleep measurements. No adverse safety events were reported. The novel device provides sleep study data comparable to conventional polysomnography in pediatric patients, offering clinically identical test interpretation in nearly all cases. Its design enables flexible usage in both clinical and home settings in this population, improving accessibility of sleep disorder diagnostics. These results, combined with previous adult studies, suggest the device’s substantial equivalence to established, gold-standard PSG systems in usability, efficacy, and safety for a wide population of patients.
La marca de posición es una figura jurídica en constante discusión, especialmente en relación con la difícil delimitación de sus perfiles. Uno de los elementos más controvertidos en este punto es el carácter distintivo de este tipo de signos, y muy en particular cuando aparecen unidos a otras clases de signos dentro de la misma marca como un todo. Esta ha sido la cuestión recientemente elevada ante el tribunal general de la ue, en lo tocante a una marca mixta, cromática y de posición. En este trabajo se pretende analizar el pronunciamiento en el que se ha resuelto sobre este asunto, teniendo en cuenta las posibles repercusiones de este importante fallo en la futura jurisprudencia de la ue en materia de marcas. Finalmente, se formula una valoración crítica.
El trabajo analiza la necesaria suficiencia de la declaración de la víctima de violencia de género para fundamentar una sentencia de condena cuando constituye la única prueba incriminatoria. Otorgar el valor de única prueba de cargo a la declaración de la víctima requiere encontrar un equilibrio entre dos elementos fundamentales: el derecho a la presunción de inocencia del presunto autor del delito y la expectativa de justicia de la víctima. A estos efectos, el Tribunal Supremo ha establecido unos parámetros que permiten determinar cuándo la declaración de la víctima puede adquirir el valor de prueba testifical incriminatoria: credibilidad, uniformidad, corroboración y persistencia. Ahora bien, las circunstancias particulares en que se encuentra la víctima de violencia de género obligan a una adaptación de estos requisitos establecidos con carácter general. Su análisis desde la óptica de la perspectiva de género ayuda al juez a valorar la declaración emitida minimizando el riesgo de insuficiencia probatoria.
