Measurements of the inclusive W and Z boson production cross sections and their ratios in proton-proton collisions at TeV
No full textMeasurements are presented of the W and Z boson production cross sections in proton-proton collisions at a center-of-mass energy of 13.6 TeV. Data collected in 2022 and corresponding to an integrated luminosity of 5.01 fb−1 with one or two identified muons in the final state are analyzed. The results for the products of total inclusive cross sections and branching fractions for muonic decays of W and Z bosons are (acceptance) nb for W+ boson production, (acceptance) nb for W− boson production, and (acceptance) nb for the Z boson production in the dimuon mass range of 60–120 GeV, all with negligible statistical uncertainties. Furthermore, the corresponding fiducial cross sections, as well as cross section ratios for both fiducial and total phase space, are provided. The ratios include charge-separated results for W boson production (W+ and W−) and the sum of the two contributions (W±), each relative to the measured Z boson production cross section. Additionally, the ratio of the measured cross sections for W+ and W− boson production is reported. All measurements are in agreement with theoretical predictions, calculated at next-to-next-to-leading order accuracy in quantum chromodynamics
The Hypocrisy of Signs : Inner Spaces, Language and Action in the Age of Early Modern Inquisitions
No full textThis book explores the tensions between text and speech, intention and action, individual conscience and the public sphere in the early modern period. It reclaims the hermeneutical foundation of hypocrisy as a key tool for assessing the gap between interiority and exteriority, which underpins these dyads. Secular and religious authorities of the time led unprecedented repressive campaigns that brought those tensions fully into view. Analyzing them offers new perspectives on the quandaries concerning action that arose at the threshold of modernity, as well as on the ways human behavior continues to be interpreted today
Inferring hypoxia-responsive regulators of cell fate in plant meristems through single-cell transcriptomics
Full text linkSingle-cell sequencing (scRNA-seq) is transforming our ability to dissect cell type-specific gene
regulatory networks underlying developmental processes and cellular differentiation with
unprecedented resolution. By leveraging single-cell transcriptomes of Arabidopsis thaliana shoot and
root apical meristems, we aimed to dissect the complex spatiotemporal interplay between stem cell
identity and hypoxia. Single-cell transcriptomic profiling demonstrated a substantial overlap between
hypoxia-responsive gene expression and stem cell markers across shoot and root meristems.
Trajectory inference coupled with RNA velocity revealed that hypoxia-related transcriptional
signatures are enriched in undifferentiated stem cells and gradually decline as differentiation
progresses, supporting a critical role for hypoxia in cell fate determination. Our findings suggest that
the activation of hypoxia signaling may be a conserved feature in the shoot and root apical meristems
of Arabidopsis thaliana and could play a crucial role in regulating stem cell fate decisions during
development
Les Catholiques et leur Roi: Pierre Matthieu et la fin des guerres de religion (1585-1595)
No full textLongtemps réduit à l’image d’un ligueur marginal, Pierre Matthieu (1563–1621), juriste, historien et dramaturge franc-comtois, apparaît comme l’un des représentants les plus éloquents du catholicisme exclusiviste, majoritaire en France durant toute la période des guerres de religion, et trop souvent confondu, à tort, avec la Ligue.
L’examen de ses œuvres, de sa culture et de son ancrage lyonnais permet une relecture d’ensemble de son engagement et, à travers lui, de la culture politique des catholiques français dans la seconde moitié du XVIe siècle. Il met en lumière l’existence d’un catholicisme militant, non nécessairement ligueur, de portée transnationale et forgé dans l’esprit de la Contre-Réforme, qui œuvre activement à la confessionnalisation du royaume.
Dans cette perspective, la fin des guerres de religion n’apparaît plus comme le triomphe d’une autonomisation du politique, mais comme l’aboutissement d’un projet de restauration religieuse porté par la majorité des catholiques
Distinct spatial distribution of potentiated dendritic spines in encoding- and recall-activated hippocampal neurons
Full text linkExperimental advancements in neuroscience have identified cellular engrams—ensembles of neurons whose activation is necessary and sufficient for memory retrieval. Synaptic plasticity, including long-term potentiation, is fundamental to memory encoding and recall, but the relationship between learning-induced dendritic spine potentiation and neuron-wide activation remains unclear. In this study, we employed a post-synaptic translation-dependent reporter consistent with potentiation (SA-PSDΔVenus) and a neuronal activation reporter (ESARE-dTurquoise) to determine their spatiotemporal correlation in the mouse hippocampal CA1 following contextual fear conditioning (CFC). SA-PSDΔVenus+ spines were enriched in ESARE-dTurquoise+ neurons, with distribution varying across CA1 layers at different phases of memory: SA-PSDΔVenus+ were more frequent in activated neurons in stratum oriens and stratum lacunosum moleculare after CFC (encoding), while recall-activated neurons showed a larger number of SA-PSDΔVenus+ in the stratum radiatum. These findings demonstrate that the relative weight and spatial distribution of potentiated synaptic inputs to hippocampal CA1 pyramidal neurons change between the encoding and retrieval phases of memory
Dark walker in the early universe : a strongly coupled sector model
Full text linkWe explore the phenomenology of the “Dark Walker”—an SU(3) theory with eight flavors of massless fundamental
fermions in the dark sector. During inflation, its walking dynamics generate primordial non-Gaussianities through
the exchange of unparticles, while accounting for the current dark matter relic abundance if we consider freeze-
in of Dark Walker coupled to the Standard Model through the Higgs portal. This provides a simple yet predictive
example linking strongly coupled inflationary dynamics to present-day dark matter
A model-independent measurement of the CKM angle gamma in the decays B^{\pm} \to [K+K-pi+pi-]Dh^{\om} and B^{\pm}-> [pi+pi-pi+pi-]Dh^{\pm} (h = K, \pi)
No full textA model-independent determination of the CKM angle γ is presented, using the B^{\pm} -> [K+K-pi+pi-]Dh^{\pm} and B^{\pm} \to [pi+pi-pi+pi-]Dh^{\pm} decays, with h = K, pi. This measurement is the first phase-space binned study of these decay modes, and uses a sample of proton-proton collision data collected by the LHCb experiment, corresponding to an integrated luminosity of 9 fb-1. The phase-space bins are optimised for sensitivity to gamma, and in each bin external inputs from the BESIII experiment are used to constrain the charm strong-phase parameters. The result of this binned analysis is gamma =53.9 -8.9 +9.5 degrees, where the uncertainty includes both statistical and systematic contributions. Furthermore, when combining with existing phase-space integrated measurements of the same decay modes, a value of gamma=52.6-6.4+8.5 degrees is obtained, which is one of the most precise determinations of gamma to date
Costanti e innovazioni nell'onomastica vercellese fra XIII e XV secolo
No full textIl saggio analizza l'evoluzione dell'onomastica nell'area del Vercellese storico (attuali province di Vercelli e Biella) fra XIII e XV secolo. Il Quattrocento offre la base di dati più omogenea e completa, grazie a un’inchiesta fiscale promossa dai duchi di Savoia fra il 1459-60: il liber focorum redatto in quell'occasione copre la città di Vercelli e un centinaio di comunità del distretto, restituendo per ognuna un censimento dei fuochi «cum nominibus et cognominibus» che comprende anche i miserabiles. Il Trecento si avvale delle fonti fiscali seriali per la città, e dei conti di castellania sabaudi per il distretto, mentre il Duecento è agevolato dall'ampio panorama di edizioni piemontesi promosse dalla Biblioteca della Società Storica Subalpina. L'insieme di queste fonti ha restituito una base di dati costituita da circa 20.000 nomi, utilizzata per descrivere le variazioni nel tempo del repertorio onomastico, e per porre alcune questioni di ordine metodologico. Il saggio si sofferma sui condizionamenti delle fonti, sul problema di come trattare le forme derivate, sul nome come espressione di appartenenze identitarie locali e sovralocali, sulle ragioni che determinano le improvvise fortune onomastiche di alcuni nomi
Introduction: An Edible Lieu de Mémoire: Food, Memory and Oral History in Practice, in Culinary Chronicles: Oral Histories of Food Mobility and Belonging
No full textThis edited volume brings together a collection of oral histories that explore how food carries memory across generations, geographies, and histories. Centered on interviews with elders, the chapters trace various journeys from Italy to Switzerland, Bulgaria to Turkey, and across regions of India, revealing how migration, war, gender roles, and political upheaval shape culinary practices. From antifascist pastasciutta to Maharashtrian home cooking, each contribution shows how recipes, kitchen spaces, and shared meals function as living archives of resilience and belonging. Blending scholarly insight with creative expression, the book positions food as both intimate memory and collective history, inviting readers to see their own family tables as sites of remembrance
