No full textOptical characterization of the Advanced Virgo gravitational wave detector for the O4 observing run
No full textThe Advanced Virgo Plus detector, an upgrade of the Advanced Virgo Detector, is a dual-recycled Fabry–Perot Michelson interferometer characterized by 3 km long arm cavities. The main upgrades in view of the fourth observing run (O4) were the implementation of the signal recycling cavity and the installation of the frequency-dependent squeezing system. Another upgrade was the increasing of the laser power at the input of the detector, which could lead to more severe thermal aberrations impacting the achievement of the interferometer optimal working point. Therefore, the fine-tuning of the thermal compensation system, optimized with respect to the one implemented for the O3 run, was also challenging. In order to achieve the best performance of such a sophisticated optical system, having a clear knowledge of all its optical parameters is crucial. The optical characterization of the detector in different working conditions could help in understanding its behavior and optimizing the global control system. Moreover, the characterization in different thermal conditions, i.e., different values of the input laser power or different configurations of the thermal compensation system, could provide significant guidance for the optimization of the thermal tuning. In this paper, we will describe all the methodologies adopted for the optical characterization activities performed in Advanced Virgo Plus, presenting the experimental results for all the relevant parameters obtained during the preparation of the O4 run
Entrevista con Monapaküy, Organización Comunitaria. El activismo de las mujeres, la defensa de la tierra y la comunalidad en San Mateo del Mar (Oaxaca, México)
No full textEntrevista a tres mujeres ikoots - müm Bety, müm Rosy y müm Gisela -, promotoras de una organización comunitaria llamada "Monapaküy" (bienestar), surgida en San Mateo del Mar (Istmo de Tehuantepec, México) durante las fases de emergencia posteriores al sismo de 2017, en un período de gran desorientación y faccionalismo político debido a la injerencia de fuertes intereses económicos en la explotación de los recursos de la región. "Monapaküy" ha abierto en la comunidad nuevos caminos de activismo femenino. A través del empoderamiento de las mujeres, la búsqueda de un bienestar integral se entreteje y se sostiene con la defensa del territorio, el cuidado del medio ambiente, el fortalecimiento de la lengua indígena y la construcción de una comunalidad inclusiva basada en la custodia de la asamblea comunitaria y la práctica del tequio.
Los temas de la entrevista reflejan, por ende, los grandes ejes planteados hoy por los movimientos indígenas en los debates públicos nacionales y en los foros globales - la reivindicación integral de los derechos indígenas, ambientales y de género -, que pasan cada vez más por la toma de la palabra y la conquista de espacios de acción por parte de las mujeres, como lo testimonian aquí müm Bety, müm Rosy y müm Gisela
Violenza di genere e vuoti terminologici: il caso del francese e dell’italiano
No full textIl contributo affronta l’odioso tema della violenza sulle donne attraverso un approfondimento terminologico in prospettiva comparativa italiano-francese. Partendo dai termini raccolti nei glossari della sezione YourTerm FEM del progetto europeo Terminology without borders, si sono identificati i legami fra le unità terminologiche relative al campo semantico in questione.
I risultati dell'analisi confermano le carenze e i vuoti terminologici in entrambe le lingue considerate, che impediscono di rendere visibile e di denunciare il carattere sessista di diverse forme di violenza commesse ai danni delle donne in quanto donne
Synthetic data sets for person Re-Identification: A critical analysis
No full textSupervised methods for person Re-Identification (Re-Id) need extensive manual annotation, limiting data set size and the resulting generalisation capability to unseen target data. Unsupervised methods avoid manual annotation but typically attain a lower performance. Synthetic training data can mitigate these issues, as they allow generating large data sets encompassing more representative variations in visual factors such as background scenes and pedestrian appearance without requiring manual annotation and without privacy issues arising from recent regulations. Existing synthetic data sets vary in size, diversity of human models, camera views, backgrounds, as well as photorealism. It is, however, not yet clear how all such factors affect Re-Id performance. We conduct a comprehensive and systematic analysis and experimental evaluation of existing synthetic data sets, to understand how the main factors characterising them affect the generalisation capability to real data. Our results provide useful guidelines towards developing effective synthetic data sets for Re-Id
Comparative proteomics analysis of MRSA under different experimental conditions
No full textThe ability of methicillin-resistant Staphylococcus aureus (MRSA) to adapt to environmental stressors is crucial for its survival and persistence. This study used shotgun proteomics to analyze the protein profiles of MRSA strains ST398 and JE2 under three experimental conditions: EC1 (control, 37 °C, pH 7), EC2 (35 °C, pH 6), and EC3 (35 °C, pH 6 with 5% NaCl). Proteins were extracted and digested with trypsin using filter-aided sample preparation (FASP), followed by LC–MS/MS analysis. Raw data were analyzed using Proteome Discoverer software with label-free quantification (LFQ), identifying an average of 2640 ± 70 and 2832 ± 154 proteins in ST398 and JE2, respectively. Qualitative and quantitative differences in protein expression were observed between strains and conditions. Under EC2, ABC transporters increased and arginine metabolism was upregulated, suggesting metabolic adaptation to acidic stress. Purine metabolism was downregulated, indicating a metabolic shift. Under EC3 condition, NaCl addition induced glycine-betaine biosynthesis and proteins involved in potassium limitation. JE2 exhibited a more pronounced oxidative and stress response under salt stress, indicating a strain-specific adaptation. These findings highlight strain-specific proteomic responses in MRSA, highlighting the roles of arginine, glycine-betaine, and purine metabolism, along with stress-response proteins, in coping with environmental stressors
