Study of the energy dependence of the underlying event in proton-antiproton collision

We study charged particle production (pT>0.5??GeV/c, |?|<0.8) in proton-antiproton collisions at total center-of-mass energies vs=300??GeV, 900 GeV, and 1.96 TeV. We use the direction of the charged particle with the largest transverse momentum in each event to define three regions of ?-? space: “toward”, “away”, and “transverse.” The average number and the average scalar pT sum of charged particles in the transverse region are sensitive to the modeling of the “underlying event.” The transverse region is divided into a MAX and MIN transverse region, which helps separate the “hard component” (initial and final-state radiation) from the “beam-beam remnant” and multiple parton interaction components of the scattering. The center-of-mass energy dependence of the various components of the event is studied in detail. The data presented here can be used to constrain and improve QCD Monte Carlo models, resulting in more precise predictions at the LHC energies of 13 and 14 TeV.We thank the Fermilab staff and the technical staffs of theparticipating institutions for their vital contributions.

Frustuli di manoscritti greci a Troina in Sicilia

Sono segnalati alcuni frammenti pergamenacei di due distinti manoscritti italogreci del secolo XII, utilizzati nell�indorsatura di tre edizioni a stampa cinquecentesche, ora in possesso della Biblioteca Comunale di Troina, in Sicilia. I frammenti, latori di brani del Commento al Vangelo di Matteo di Giovanni Crisostomo e di un libro liturgico (Triodio), sono inquadrati nel contesto della storia culturale di Troina medioevale. Una lunga premessa si sofferma, inoltre, sulla dispersione del patrimonio librario manoscritto della Sicilia greca, in cui è da segnalare, fra l�altro, la corrispondenza tra Guglielmo Sirleto (� 1584) e il messinese Francesco Antonio Napoli (� 1589) circa i manoscritti greci del monastero del S. Salvatore di Palermo

Quasi-invariance of Gaussian measures for the periodic Benjamin-Ono-BBM equation

The BBM equation is a Hamiltonian PDE which revealed to be a very interesting test-model to study the transformation property of Gaussian measures along the flow. In this paper we study the BBM equation with critical dispersion (which is a Benjamin-Ono type model). We prove that the image of the Gaussian measures supported on fractional Sobolev spaces of increasing regularity are absolutely continuous, but we cannot identify the density, for which new ideas are needed

<i>In situ</i> skeletonized bilateral thoracic artery for left coronary circulation: a 20-year experience

OBJECTIVES Our goal was to analyse the outcomes in a patient population using a standardized technique for coronary artery bypass grafting (CABG) consisting of total arterial myocardial revascularization utilizing the in situ skeletonized bilateral thoracic artery for left coronary circulation. We also explored potential predictors of long-time unfavourable outcomes. METHODS Patients undergoing total arterial myocardial revascularization using in situ skeletonized bilateral thoracic artery for left coronary circulation between January 1997 and May 2017 were included prospectively in this study. The median follow-up (100% complete) was 103 months (interquartile range 61–189 months) and ranged from 1 to 245 months. RESULTS A total of 1325 consecutive patients were recruited. During the follow-up period, there were 131 deaths (9.8%), 146 repeat revascularizations (11.0%) and 229 major adverse cardiac events (17.2%). The 18-year freedom from major adverse cardiac events was 62.6 ± 9.3%, 62.5 ± 6.3% and 53.9 ± 11.0%, respectively. Multivariable models showed that a left ventricular ejection fraction ≤35%, chronic obstructive pulmonary disease, peripheral vascular disease (P P = 0.002) were independent predictors of diminished long-term survival. Moreover, peripheral vascular disease and off-pump coronary artery bypass (both, P P < 0.001). CONCLUSIONS Coronary artery bypass using the in situ skeletonized bilateral thoracic artery for left coronary circulation configuration for total arterial myocardial revascularization resulted in satisfactory long-term results with a low incidence of death and late events and may represent a technique of choice in selected patients having CABG. Larger and long-term prospective studies are, however, warranted

Neuronal and astrocytic involvement in striped dolphins (Stenella coeruleoalba) with morbilliviral encephalitis.

Dolphin morbillivirus (DMV), a highly pathogenic agent, may cause peculiar, "brain-only" forms of infection (BOFDI), in which viral antigen and/or genome is found exclusively in the brain from striped dolphins (Stenella coeruleoalba). These BOFDIs show morphopathological similarities with subacute sclerosing panencephalitis and old dog encephalitis (ODE) in measles virus-infected patients and in canine distemper virus-infected dogs, respectively. The brain tissue from 3 BOFDI-affected striped dolphins was investigated by means of double labelling-indirect immunofluorescence (DL-IIF) and ultrastructurally, in order to characterize the DMV-targeted neuronal and non-neuronal cell populations, along with the associated submicroscopic findings. Viral colonization of calbindin-immunoreactive (IR) and nitric oxide synthase-IR neurons was detected in the cerebral parenchyma from the 3 DMV-infected dolphins under study, associated with nuclear (chromatin) and cytoplasmic (mitochondrial) ultrastructural changes. Furthermore, a limited viral targeting of brain astrocytes was found in these animals, all of which exhibited a prominent astrogliosis/astrocytosis. To the best of our knowledge, those herein reported should be the first submicroscopic pathology and neuropathogenetic data about BOFDI in striped dolphins. In this respect, the marked astrogliosis/astrocytosis and the low viral colonization of brain astrocytes in the 3 DMV-infected dolphins under investigation are of interest from the comparative pathology and viral neuropathogenesis standpoints, when compared with ODE-affected dogs, in whose brain a non-cytolytic, astrocyte-to-astrocyte infectious spread has been recently documented. Further studies aimed at characterizing the complex DMV-host interactions in BOFDI-affected striped dolphins are needed

Healthcare practices and Human-Centred Management principles during the COVID-19 pandemic. The Italian experience.

This book is part of the Human Centered Book Trilogy, the 2021 volumes of the Routledge Human Centered Management HCM Series. HCM books are pioneering transformation from the traditional humans-as-a-resource approach of the industrial past, to the humans at the center management and organizational paradigm of the 21st century. HCM is built on talent and wellbeing of people in the workplace driving work engagement, quality standards, high performance and productivity for long-term organizational sustainability in the global VUCA (volatile, uncertain, complex, ambiguous) environment. This book was carefully crafted by recognized international human centered scholars from four continents. Although all organizations seek to have an optimal culture, unstoppable disruptions in the VUCA environment easily derail even the best efforts. Conventional assumptions of culture as a unifying organizational force are hardly defendable today. HCM maintains that culture is not only about cohesiveness and consensus but effective management of conflict and disagreements continuously testing the capacity of people to work together. This book is about organizational transformation positioning people at the center. Complementary chapters integrate as antidotes to overcome disruptions in the VUCA environment and the effects of the COVID-19 pandemic affecting people and organizations worldwide. This and its two complementary titles Soft Skills for Human Centered Management and Global Sustainability and Sensible Leadership: Human Centered, Insightful and Prudent are timely readings for leaders, managers, researchers, academics, practitioners, students and the general public responsible for organizations across industries and sectors worldwide pursuing quality standards and organizational transformation to attain sustaina
