    EnIt is not among the terms that most often occurs in the writings of Tonino Bello, but there isn't a page, as well as there was not a day of his life, in which Mercy was not the main theme of that plot that even today still smacks of novelty. Shepherd of Mercy, he left a trace each day in his city until he changed the course of history: the poor of his city, the humble, have become in his writings, in his life, in his church the protagonists. Don Tonino captures the drama of the historical moment: he suffers for the pains of God, the world's first waste. He suffers for the pains of the panting world, gripped by the sufferings of wars, an unhappy world that does not know how to get rid of the deceit of the money, a world today slave of a wild economy, a world unable to protect its home from the logic of dominion. He suffers for his Church and warns: There is no more time to lose. In order for the church to be saved it must have this perspective: start again from humble! And he encourages it, urges it to show a new boldness. How happy we are in the suburbs when we see that in Rome a welcome towards the third word people is diplayed, or when (the Church) fights for the recognition of the poor's human rights; we are happy when we seethat in Rome a position in favor of the more distant people is taken! What a joy in listening to these things! Then, if a poor suburban bishop can afford it, the encouragement is this: Courage, Church of Rome, show us your excellence, because the world awaits for the testimony of the Church called to preside over charity.ItNon è tra i termini che più frequentemente ricorre tra gli scritti di Tonino Bello, ma non c'è una pagina, così come non c'è stato un giorno della sua vita, in cui la misericordia non sia stata il filo conduttore di quella trama che ancora oggi profuma di novità. Pastore di misericordia ha segnato ogni giorno la sua città sino a cambiarne il corso della storia: i poveri della sua città, gli ultimi, sono diventati nei suoi scritti, nella sua vita, nella sua chiesa i protagonisti. Don Tonino coglie la drammaticità del momento storico: soffre per i dolori di Dio, primo scarto del mondo. Soffre per i dolori del mondo ansimante, attanagliato dalle sofferenze delle guerre, un mondo infelice che non sa liberarsi dall'inganno del denaro, un mondo oggi schiavo di un'economia selvaggia, un mondo incapace di proteggere la propria casa dalla logica del dominio. Soffre per la sua chiesa e la ammonisce: Non c'è più tempo da perdere. La chiesa per potersi salvare deve avere questa prospettiva: ripartire dagli ultimi! E la incoraggia, la esorta a manifestare un'audacia nuova. Come siamo felici in periferia quando vediamo che a Roma si manifesta accoglienza verso i terzomondiali o ci si batte perché ai poveri si riconoscano i diritti umani; come siamo lieti quando constatiamo che a Roma si prende posizione in favore dei popoli più lontani! Che gioia nell'ascoltare queste cose! Allora, se un povero vescovo di periferia può permetterselo, l'incoraggiamento è questo: Coraggio chiesa di Roma, manifestaci la tua esemplarità perché il mondo attende la testimonianza della chiesa chiamata a presiedere la carità

    Search for gravitational-lensing signatures in the full third observing run of the LIGO-Virgo network

    Gravitational lensing by massive objects along the line of sight to the source causes distortions of gravitational wave-signals; such distortions may reveal information about fundamental physics, cosmology and astrophysics. In this work, we have extended the search for lensing signatures to all binary black hole events from the third observing run of the LIGO--Virgo network. We search for repeated signals from strong lensing by 1) performing targeted searches for subthreshold signals, 2) calculating the degree of overlap amongst the intrinsic parameters and sky location of pairs of signals, 3) comparing the similarities of the spectrograms amongst pairs of signals, and 4) performing dual-signal Bayesian analysis that takes into account selection effects and astrophysical knowledge. We also search for distortions to the gravitational waveform caused by 1) frequency-independent phase shifts in strongly lensed images, and 2) frequency-dependent modulation of the amplitude and phase due to point masses. None of these searches yields significant evidence for lensing. Finally, we use the non-detection of gravitational-wave lensing to constrain the lensing rate based on the latest merger-rate estimates and the fraction of dark matter composed of compact objects

    Search for eccentric black hole coalescences during the third observing run of LIGO and Virgo

    Despite the growing number of confident binary black hole coalescences observed through gravitational waves so far, the astrophysical origin of these binaries remains uncertain. Orbital eccentricity is one of the clearest tracers of binary formation channels. Identifying binary eccentricity, however, remains challenging due to the limited availability of gravitational waveforms that include effects of eccentricity. Here, we present observational results for a waveform-independent search sensitive to eccentric black hole coalescences, covering the third observing run (O3) of the LIGO and Virgo detectors. We identified no new high-significance candidates beyond those that were already identified with searches focusing on quasi-circular binaries. We determine the sensitivity of our search to high-mass (total mass M>70 M⊙) binaries covering eccentricities up to 0.3 at 15 Hz orbital frequency, and use this to compare model predictions to search results. Assuming all detections are indeed quasi-circular, for our fiducial population model, we place an upper limit for the merger rate density of high-mass binaries with eccentricities 0<e≤0.3 at 0.33 Gpc−3 yr−1 at 90\% confidence level

    Ultralight vector dark matter search using data from the KAGRA O3GK run

    Among the various candidates for dark matter (DM), ultralight vector DM can be probed by laser interferometric gravitational wave detectors through the measurement of oscillating length changes in the arm cavities. In this context, KAGRA has a unique feature due to differing compositions of its mirrors, enhancing the signal of vector DM in the length change in the auxiliary channels. Here we present the result of a search for U(1)B−L gauge boson DM using the KAGRA data from auxiliary length channels during the first joint observation run together with GEO600. By applying our search pipeline, which takes into account the stochastic nature of ultralight DM, upper bounds on the coupling strength between the U(1)B−L gauge boson and ordinary matter are obtained for a range of DM masses. While our constraints are less stringent than those derived from previous experiments, this study demonstrates the applicability of our method to the lower-mass vector DM search, which is made difficult in this measurement by the short observation time compared to the auto-correlation time scale of DM

    Metastases of hepatocellular carcinoma misdiagnosed as isolated hypertrophic cardiomyopathy

    At present, cardiac metastasis of hepatocellular carcinoma is rarely mentioned in the literature. We report a hepatocellular carcinoma patient with cardiac metastasis misdiagnosed as hypertrophic cardiomyopathy in 2011. Two years later, on presentation of syncope, an abnormal ventricular septal size was recorded by ultrasound scan, and was subsequently shown by magnetic resonance imaging to be a tumour lesion. A myocardial biopsy confirmed infiltration of hepatocellular carcinoma. This observation underlines the risk of hepatocellular carcinoma cardiac metastasis, manifested in its infiltrative form as hypertrophic cardiomyopathy. In conclusion, we suggest that the ultrasound appearance of hypertrophic cardiomyopathy in hepatocellular carcinoma patients should be seen as a “red flag” and recommend the introduction of magnetic resonance imaging assessment of transplant candidates

    Importance: Most epidemiological studies of heart failure (HF) have been conducted in high-income countries with limited comparable data from middle- or low-income countries. Objective: To examine differences in HF etiology, treatment, and outcomes between groups of countries at different levels of economic development. Design, Setting, and Participants: Multinational HF registry of 23 341 participants in 40 high-income, upper–middle-income, lower–middle-income, and low-income countries, followed up for a median period of 2.0 years. Main Outcomes and Measures: HF cause, HF medication use, hospitalization, and death. Results: Mean (SD) age of participants was 63.1 (14.9) years, and 9119 (39.1%) were female. The most common cause of HF was ischemic heart disease (38.1%) followed by hypertension (20.2%). The proportion of participants with HF with reduced ejection fraction taking the combination of a β-blocker, renin-angiotensin system inhibitor, and mineralocorticoid receptor antagonist was highest in upper–middle-income (61.9%) and high-income countries (51.1%), and it was lowest in low-income (45.7%) and lower–middle-income countries (39.5%) (P < .001). The age- and sex- standardized mortality rate per 100 person-years was lowest in high-income countries (7.8 [95% CI, 7.5-8.2]), 9.3 (95% CI, 8.8-9.9) in upper–middle-income countries, 15.7 (95% CI, 15.0-16.4) in lower–middle-income countries, and it was highest in low-income countries (19.1 [95% CI, 17.6-20.7]). Hospitalization rates were more frequent than death rates in high-income countries (ratio = 3.8) and in upper–middle-income countries (ratio = 2.4), similar in lower–middle-income countries (ratio = 1.1), and less frequent in low-income countries (ratio = 0.6). The 30-day case-fatality rate after first hospital admission was lowest in high-income countries (6.7%), followed by upper–middle-income countries (9.7%), then lower–middle-income countries (21.1%), and highest in low-income countries (31.6%). The proportional risk of death within 30 days of a first hospital admission was 3- to 5-fold higher in lower–middle-income countries and low-income countries compared with high-income countries after adjusting for patient characteristics and use of long-term HF therapies. Conclusions and Relevance: This study of HF patients from 40 different countries and derived from 4 different economic levels demonstrated differences in HF etiologies, management, and outcomes. These data may be useful in planning approaches to improve HF prevention and treatment globally
