Only 3 cases of coronavirus disease 2019 (COVID-19) were identified in Italy in the first half of February 2020 and all involved people who had recently traveled to China. On February 20, 2020, a severe case of pneumonia due to SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2) was diagnosed in northern Italy’s Lombardy region in a man in his 30s who had no history of possible exposure abroad. Within 14 days, many other cases of COVID-19 in the surrounding area were diagnosed, including a substantial number of critically ill patients.1 On the basis of the number of cases and of the advanced stage of the disease it was hypothesized that the virus had been circulating within the population since January. Another cluster of patients with COVID-19 was simultaneously identified in Veneto, which borders Lombardy. Since then, the number of cases identified in Italy has rapidly increased, mainly in northern Italy, but all regions of the country have reported having patients with COVID-19. After China, Italy now has the second largest number of COVID-19 cases2 and also has a very high case-fatality rate.3 This Viewpoint reviews the Italian experience with COVID-19 with an emphasis on fatalities.

Background: The history of radical hernia repair involves a period of intense surgical activity, influenced by factors of the time such as social development, hygiene, anesthesia, and antisepsis. Subcutaneous surgery, the initial option designed to avoid infections and peritonitis, was modified after the introduction of antisepsis, eventually leading to dissection surgery. Objective: We aim to analyze the publications from the period of radical hernia cures using current methodology, verifying when and how the transition occurred from subcutaneous surgery to dissection surgery. Methods: A literature review of the databases PubMed, LILACS, Cochrane Library, “Google” and university libraries is conducted. The following keywords were used: “anatomy and surgery”. A critical analysis of the known literature about this historical topic is carried out. Results: Under-vision dissection surgery, through incision of the aponeurosis of the external oblique muscle, began in England by Durham in 1866, almost 20 years before it was performed in France by Lucas-Championnière in 1885. Recurrences decreased after the introduction of the principle of closing the walls of the inguinal canal (Wood, 1860). The surgeon–anatomist Wood should be considered the first specialist in abdominal wall surgery, due to his extensive contributions from the pre-antiseptic era. The evolution of the radical cure of hernias was made possible by combining the knowledge of several countries: England, Germany, and Italy. Conclusions: Dissection surgery was initiated in England, Germany, and Italy, not in France. The influence of the French literature on the history of hernias is evident, to the detriment of the contributions of surgeons from other countries.

The first monographic exhibition dedicated to Vittore Carpaccio (ca. 1460–1525) in the US, and the first outside of Italy, was hosted at the National Gallery of Art in Washington, DC, from 20 Nov 2022 to 23 February 2023 (from where it went to Venice). Building on the research of art historians and experts on Venice and the larger Mediterranean region in the early modern period, this paper examines Carpaccio’s depiction of various “Turks” in some of the large narrative painting cycles (<i>teleri</i>) commissioned by the devotional confraternities (<i>scuole</i>) in Renaissance Venice. While Carpaccio’s and the larger Venetian familiarity with Islam, including Turks, has been studied, this paper compares various female figures in the St. Stephen cycle with those in his St. George cycle, situating them in the larger historical context of the commissioning <i>scuole</i> (Scuola di Santo Stefano and Scuola di San Giorgio degli Schiavoni, respectively). While attempting to uncover the significance, if not the identities, of a few individuals who stand out from the crowd, this paper urges caution when attempting to discern social history from a painting, much as we take literary texts (particularly those written well before our own times) with a grain of salt.

This study presents a multi-resolution and multi-temporal remote sensing approach to assess human-induced changes in cultural landscapes, with a focus on the archaeological site of Amrit (Syria) within the MapDam project. By integrating satellite archives (KH, Landsat series, NASADEM) with ancillary geospatial data (OpenStreetMap) and advanced analytical methods, four decades (1984–2024) of land-use/land-cover (LULC) change and shoreline dynamics were reconstructed. Machine learning classification (Random Forest) achieved high accuracy (Test Accuracy = 0.94; Kappa = 0.89), enabling robust LULC mapping, while predictive modelling of urban expansion, calibrated through a Gradient Boosting Machine, attained a Figure of Merit of 0.157, confirming strong predictive reliability. The results reveal path-dependent urban growth concentrated on low-slope terrains (≤5°) and consistent with proximity to infrastructure, alongside significant shoreline regression after 1974. A Business-as-Usual projection for 2024–2034 estimates 8.676 ha of new anthropisation, predominantly along accessible plains and peri-urban fringes. Beyond quantitative outcomes, this study demonstrates the replicability and scalability of open-source, data-driven workflows using Google Earth Engine and Python 3.14, making them applicable to other high-risk heritage contexts. This transparent methodology is particularly critical in conflict zones or in regions where cultural assets are neglected due to economic constraints, political agendas, or governance limitations, offering a powerful tool to document and safeguard endangered archaeological landscapes.

We present JWST NIRCam observations of the emerging young star clusters (eYSCs) detected in the nearby spiral galaxy M83. The NIRcam mosaic encompasses the nuclear starburst, the bar, and the inner spiral arms. The eYSCs, detected in Pa α and Br α maps, have been largely missed in previous optical campaigns of young star clusters (YSCs). We distinguish between eYSCI, if they also have compact 3.3 μ m polycyclic aromatic hydrocarbon (PAH) emission associated with them, and eYSCII, if they only appear as compact Pa α emitters. We find that the variations in the 3.3 μ m PAH feature are consistent with an evolutionary sequence where eYSCI evolve into eYSCII and then optical YSCs. This sequence is clear in the F300M​​​​​​−F335M (tracing the excess in the 3.3 μ m PAH feature) and the F115W−F187N (tracing the excess in Pa α ) colors, which become increasingly bluer as clusters emerge. The central starburst stands out as the region where the most massive eYSCs are currently forming in the galaxy. We estimate that only about 20% of eYSCs will remain detectable as compact YSCs. Combining eYSCs and YSCs (≤10 Myr), we recover an average clearing timescale of 6 Myr in which clusters transition from embedded to fully exposed. We see evidence of shorter emergence timescales (∼5 Myr) for more massive (>5 × 10 ^3 M _⊙ ) clusters, while star clusters of ∼10 ^3 M _⊙ about 7 Myr. We estimate that eYSCs remain associated with the 3.3 μ m PAH emission for 3–4 Myr. Larger samples of eYSC and YSC populations will provide stronger statistics to further test environmental and cluster mass dependencies on the emergence timescale.

Introduction: Pneumococcal vaccination has significantly decreased the burden of invasive pneumococcal disease in the general population, however studies on effectiveness in Down syndrome (DS) are heterogeneous. In this cross-sectional study we evaluated the prevalence of adequate immune response in children with DS after pneumococcal vaccination and we searched for possible clinical predictors associated with it, in order to provide data to optimize vaccination strategies in this high-risk group. Methods: Data of children with DS referred to the DS outpatient Clinic of Bambino Gesù Children's Hospital, Rome, Italy, between September 2021 and March 2022 were reviewed. Clinical and laboratory predictors of immunological response to PCV vaccine, defined as an anti-pneumococcal IgG titer threshold above 0.35 μg/mL were compared and evaluated with bivariate analyses and logistic regression. Results: In this cohort of 406 patients the mean age was 8.4 years and 56.2 % of individuals were male. Most of them had congenital cardiopathy (57.8 %) and recurrent respiratory infections (57.4 %). An anti-pneumococcal Ig titer ≥0.35 μg/mL was found in 50.5 % of patients. Those with Ig < 0.35 μg/mL were significantly younger (p < 0.001) and less likely to have autoimmune disorders or hypothyroidism. Logistic regression showed that a positive history of previous surgery increased the likelihood of Ig ≥ 0.35 μg/mL (OR 2.25, p = 0.001), as well as hypothyroidism (OR 3.14, p = 0.016) and celiac disease (OR 3.70, p = 0.030). Additionally, older age at last PCV13 dose positively correlated with higher Ig levels (p = 0.018). Conclusion: Our findings confirm a lower prevalence of adequate immune response after anti-pneumococcal vaccination in individuals with DS. Older age at last PCV13 dose was found to be correlated to higher specific IgG titers; we suggest a tailored vaccination schedule or a booster dose in individuals with DS that could improve their immune protection.

Understanding the spatial distribution of strontium isotopes in plants or other archives within a region is crucial for various fields, including archaeology, environmental studies, food sciences and forensic science. This study aims to create a detailed dynamic strontium isoscape for Belgium through high-density plant sampling, presented in a web application (IsoBel) that serves the mentioned research fields. A total of 540 plant samples (199 locations), representing various species of grass, shrubs, and trees across Belgium were collected and were analysed for their strontium isotope ratios (87Sr/86Sr) to create a first biologically available strontium map. Sampling sites were selected to cover diverse lithological formations and soil types, ensuring representative coverage of the region’s geological heterogeneity, by using a novel high density grid mapping method. Sixty-four previously published plants from 21 locations are also included in this study, bringing the total amount of plant samples used to 604 from 220 locations. The results reveal significant variations in 87Sr/86Sr across Belgium (ranging from 0.7054 to 0.7259), which reflect the underlying lithology and geological processes (tectonics, weathering,…) which shaped the landscape. Although overlapping 87Sr/86Sr is seen across the majority of lithologies, there is a statistically significant difference between the distribution of 87Sr/86Sr values across all different lithological units in Belgium (Kruskal-Wallis test; p < 0.0001). Distinct regional patterns were observed, with higher 87Sr/86Sr in the older geological south-eastern part of Belgium, compared to the younger north-western parts. The high-density plant sampling approach employed in this study allowed for enhanced spatial resolution and improved accuracy in the predictive surfaces for bioavailable 87Sr/86Sr created by Empirical Bayesian Kriging (EBK). These findings provide valuable insights into the geographic distribution of strontium isotopes within Belgium and offer a foundation for future studies in archaeology, ecology, environmental studies, food sciences and forensics. Furthermore, the extensive coverage of various plant species provided a robust representation of the local ecosystems and their strontium sources. Overall, this study contributes to the growing body of knowledge on regional strontium isoscapes, enhancing our understanding of the complex interplay between litho- and biosphere in shaping the strontium isotope compositions of ecosystems.

Jan van Stinemolen (1518–1582) is an interesting artist who remains largely unknown. As he is not mentioned in Karel van Mander's Schilder-Boeck, his biography must be pieced together from archival sources and remains incomplete. These sources primarily record Stinemolen's presence in the Spanish Netherlands, first in his hometown of Mechelen and later in Antwerp. The dates of his time in Naples and southern Italy – a trip to Sicily can be inferred from one of his drawings – are unclear. Like other members of his family, he was probably primarily active as a silversmith and jeweller – a prosperous profession, although he may have been affected by the religious wars in his homeland. Nothing has survived of his work as a silversmith; apart from the spectacular View of Naples, only a few drawings remain, most of which are attributed to him on stylistic grounds. Stinemolen's particular amalgamation of topographical map and perspectival view in this panorama may have its roots in Mechelen, where urban cartography flourished in the 16th century. His fascination with landscapes created by volcanic forces is evident in his drawings. The characteristics of his panorama allow us to form further hypotheses about his artistic motivations and his interest in natural history.

Infinitesimals have seen ups and downs in their tumultuous history. In the 18th century, d'Alembert set the tone by describing infinitesimals as chimeras. Some adversaries of infinitesimals, including Moigno and Connes, picked up on the term. We highlight the work of Cauchy, Noël, Poisson and Riemann. We also chronicle reactions by Moigno, Lamarle and Cantor, and signal the start of a revival with Peano.

Classifier-free guidance (CFG) is a key technique for improving conditional generation in diffusion models, enabling more accurate control while enhancing sample quality. It is natural to extend this technique to video diffusion, which generates video conditioned on a variable number of context frames, collectively referred to as history. However, we find two key challenges to guiding with variable-length history: architectures that only support fixed-size conditioning, and the empirical observation that CFG-style history dropout performs poorly. To address this, we propose the Diffusion Forcing Transformer (DFoT), a video diffusion architecture and theoretically grounded training objective that jointly enable conditioning on a flexible number of history frames. We then introduce History Guidance, a family of guidance methods uniquely enabled by DFoT. We show that its simplest form, vanilla history guidance, already significantly improves video generation quality and temporal consistency. A more advanced method, history guidance across time and frequency further enhances motion dynamics, enables compositional generalization to out-of-distribution history, and can stably roll out extremely long videos.

The early history of string theory is marked by a shift from strong interaction physics to quantum gravity. The first string models and associated theoretical framework were formulated in the late 1960s and early 1970s in the context of the S-matrix program for the strong interactions. In the mid-1970s, the models were reinterpreted as a potential theory unifying the four fundamental forces. This paper provides a historical analysis of how string theory was developed out of S-matrix physics, aiming to clarify how modern string theory, as a theory detached from experimental data, grew out of an S-matrix program that was strongly dependent upon observable quantities. Surprisingly, the theoretical practice of physicists already turned away from experiment before string theory was recast as a potential unified quantum gravity theory. With the formulation of dual resonance models (the "hadronic string theory"), physicists were able to determine almost all of the models' parameters on the basis of theoretical reasoning. It was this commitment to "non-arbitrariness", i.e., a lack of free parameters in the theory, that initially drove string theorists away from experimental input, and not the practical inaccessibility of experimental data in the context of quantum gravity physics. This is an important observation when assessing the role of experimental data in string theory.

Italy exhibits rich linguistic diversity across its territory due to the distinct regional languages spoken in different areas. Recent advances in self-supervised learning provide new opportunities to analyze Italy's linguistic varieties using speech data alone. This includes the potential to leverage representations learned from large amounts of data to better examine nuances between closely related linguistic varieties. In this study, we focus on automatically identifying the geographic region of origin of speech samples drawn from Italy's diverse language varieties. We leverage self-supervised learning models to tackle this task and analyze differences and similarities between Italy's regional languages. In doing so, we also seek to uncover new insights into the relationships among these diverse yet closely related varieties, which may help linguists understand their interconnected evolution and regional development over time and space. To improve the discriminative ability of learned representations, we evaluate several supervised contrastive learning objectives, both as pre-training steps and additional fine-tuning objectives. Experimental evidence shows that pre-trained self-supervised models can effectively identify regions from speech recording. Additionally, incorporating contrastive objectives during fine-tuning improves classification accuracy and yields embeddings that distinctly separate regional varieties, demonstrating the value of combining self-supervised pre-training and contrastive learning for this task.

Explore the arts, culture, and history of Italy. Famous for the Colosseum in Rome, the canals of Venice, the renowned fashion houses of Milan, and the beauty of the Tuscan countryside, Italy is a vibrant tapestry of ancient landmarks and modern industry. In the 21st century, Italian history has been shaped by the transformative political influence of media mogul Silvio Berlusconi, who served multiple terms as prime minister, as well as migrant crises, a series of natural disasters, and the rise of populism culminating in the 2022 election of Giorgia Meloni, the first woman to lead Italy as prime minister. This second edition ofThe History of Italyprovides readers with an accessible and comprehensive introduction to the long and ever-evolving history of Italy and its people.

Abstract A first synthesis of available data for the period of Rome’s expansion in Italy (about 400–29 b.c.e.) shows the role of climate and environment in early Roman imperialism. Although global indices suggest a warmer phase with relatively few short-term climate events occuring around the same time as the expansion, local data emphasize the highly variable timing and expression of these trends. This variability casts doubt on ideas of a unitary, historically consequential “Roman Warm Period.” The historical importance of climate and environment to socioeconomic development merits emphasis, but should be understood in terms of evolving, contingent forms of resilience and risk-mitigating behavior by Italian communities during Roman expansion.

The paper deals with the publishing history in the post-Soviet era of three very prominent works in Gulag literature in Italian translation – Life and Fate by Vasilij Grossman, Kolyma Tales by Varlam Šalamov and The Gulag Archipelago by Aleksandr Solženicyn – in order to reconstruct their Italian reception in the years 1991-2022. The controversies surrounding the publication of these works in Italy are also discussed, and it is noted how the Italian press has paid particular attention to them, with major Italian writers reviewing the editions and contributing to their Italian reception. Finally, the lack of critical reflection by Italian Russianists on Gulag literature is discussed.

In this paper, we discuss the presence of volcanic pozzolans in the structural mortars of the Roman Temple of Nora in Sardinia (3rd c. AD), represented by pyroclastic rocks (pumices and tuffs) employed as coarse and fine aggregates. The provenance of these materials from the Phlegraean Fields was highlighted through a multi-analytical approach, involving Polarized Light Microscopy on thin sections (PLM), Scanning Electron Microscopy with Energy Dispersive Spectroscopy (SEM-EDS), Quantitative Phase Analysis by X-ray Powder Diffraction (QPA-XRPD), and X-ray Fluorescence (XRF) investigations. These volcanic pozzolans, outcropping in the Bay of Naples between Pozzuoli and the Vesuvius, are traditionally associated with the <i>pulvis puteolana</i>, the famous pozzolanic ash prescribed by Vitruvius and Pliny in order to confer strength and waterproofing capabilities to ancient concretes. This is the first evidence of the trade of this volcanic material from the Neapolitan area to Sardinia, starting at least by the Middle Imperial Age. The use of the <i>pulvis puteolana</i> in the Roman Temple of Nora seems primarily targeted to strengthen above-ground masonries, while waterproofing capabilities were not strictly pursued. This opens new questions about the construction reasons for which the demand and commercialization for this product was intended.

The formulation of a measurement theory for relativistic quantum field theory (QFT) has recently been an active area of research. In contrast to the asymptotic measurement framework that was enshrined in QED, the new proposals aim to supply a measurement framework for measurements in local spacetime regions. This paper surveys episodes in the history of quantum theory that contemporary researchers have identified as precursors to their own work and discusses how they laid the groundwork for current approaches to local measurement theory for QFT.

Francesco Guicciardini, Sidney Alexander

In 1537 Francesco Guicciardini, adviser and confidant to three popes, governor of several central Italian states, ambassador, administrator, military captain--and persona non grata with the ruling Medici after the siege of Florence--retired to his villa to write a history of his times. His Storia d'Italia became the classic history of Italy--both a brilliant portrayal of the Renaissance and a penetrating vision into the tragedy and comedy of human history in general. Sidney Alexander's readable translation and abridgment of Guicciardini's four-volume work earned the prestigious 1970 P.E.N. Club translation award. His perceptive introduction and notes add much to the understanding of Guicciardini's masterpiece.
