Il successo dei noir di Antonio Manzini e Rocco Schiavone come personaggio seriale

Lo scopo di questo saggio è spiegare il successo della ‘serie’ narrativa di Antonio Manzini imperniata sul personaggio di Rocco Schiavone, che è dovuto alla complessità con cui il personaggio è stato tratteggiato e alla capacità di fondere gli elementi strutturali tipici della 'serie' con alcuni elementi tipici della ‘saga’. L'analisi è condotta attraverso la ricostruzione della carriera narrativa di Manzini e attraverso un confronto tra il personaggio di Schiavone e quello di Montalbano, cre...

Mechanistic toxicity profiling of nicotine-rich e-liquids: mitochondrial and oxidative stress responses in ALI-exposed bronchial cells

Combustion byproducts contained in cigarette smoke are considered the main responsible for the occurring of serious chronic diseases. Aerosols from electronic cigarettes contain substantially fewer of these dangerous byproducts, potentially reducing health risks. This study examined the potential of four different commercial nicotine-rich e-liquids to induce cytotoxicity and mitochondrial dysfunction and oxidative stress in human bronchial epithelial cells (H292), using air-liquid interface (...

Redundant-baseline calibration of the hydrogen epoch of reionization array

In 21-cm cosmology, precision calibration is key to the separation of the neutral hydrogen signal from very bright but spectrally smooth astrophysical foregrounds. The Hydrogen Epoch of Reionization Array (HERA), an interferometer specialized for 21-cm cosmology and now under construction in South Africa, was designed to be largely calibrated using the self-consistency of repeated measurements of the same interferometric modes. This technique, known as redundant-baseline calibration resolves ...

Mitigating Internal Instrument Coupling for 21 cm Cosmology. II. A Method Demonstration with the Hydrogen Epoch of Reionization Array

We present a study of internal reflection and cross-coupling systematics in Phase I of the Hydrogen Epoch of Reionization Array (HERA). In a companion paper, we outlined the mathematical formalism for such systematics and presented algorithms for modeling and removing them from the data. In this work, we apply these techniques to data from HERA's first observing season as a method demonstration. The data show evidence for systematics that, without removal, would hinder a detection of the 21 c...

Absolute Calibration Strategies for the Hydrogen Epoch of Reionization Array and Their Impact on the 21 cm Power Spectrum

We discuss absolute calibration strategies for Phase I of the Hydrogen Epoch of Reionization Array (HERA), which aims to measure the cosmological 21 cm signal from the Epoch of Reionization. HERA is a drift-scan array with a 10° wide field of view, meaning bright, well-characterized point-source transits are scarce. This, combined with HERA's redundant sampling of the uv plane and the modest angular resolution of the Phase I instrument, make traditional sky-based and self-calibration techniqu...
