Abstract

In this paper we present a spectroscopic study of six double-lined binaries, five of which were recently discovered in a high-resolution spectroscopic survey of optical counterparts of stellar X-ray sources. Thanks to high-resolution spectra acquired with CAOS spectropolarimeter during seven years, we were able to measure the radial velocities of their components and determine their orbital elements. We have applied our code COMPO2 to determine the spectral types and atmospheric parameters of the components of these spectroscopic binaries and found that two of these systems are composed of main sequence stars, while the other four contain at least one evolved (giant or subgiant) component, similar to other well-known RS CVn systems. The subtraction of a photospheric template built up with spectra of non-active stars of the same spectral type as those of the components of each system has allowed us to investigate the chromospheric emission that fills in the H$\alpha$ cores. We found that the colder component is normally the one with the largest H$\alpha$ emission. None of the systems show a detectable LiI$\lambda$6708 line, with the exception of TYC 4279-1821-1, which exhibits high photospheric abundances in both components. Photometric time series from the literature allowed us to assess that the five systems with a nearly circular orbit have also photometric periods close or equal to the orbital ones, indicating spin-orbit synchronization. For the system with a highly eccentric orbit, a possible pseudo-synchronization with the periastron velocity is suggested., Comment: Accepted for publication in MNRAS. 13 pages, 12 figures

Abstract

Classical novae are cataclysmic binary star systems in which the matter of a companion star is accreted on a white dwarf (WD). Accumulation of hydrogen in a layer eventually causes a thermonuclear explosion on the surface of the WD, brightening the WD to ~10^5 solar luminosities and triggering ejection of the accumulated matter.They provide extreme conditions required to accelerate particles, electrons or protons, to high energies. Here we present the detection of gamma rays by the MAGIC telescopes from the 2021 outburst of RS Ophiuchi (RS Oph), a recurrent nova with a red giant (RG) companion, that allowed us, for the first time, to accurately characterize the emission from a nova in the 60 GeV to 250 GeV energy range. The theoretical interpretation of the combined Fermi-LAT and MAGIC data suggests that protons are accelerated to hundreds of GeV in the nova shock. Such protons should create bubbles of enhanced Cosmic Ray density, on the order of 10 pc, from the recurrent novae., Comment: THIS VERSION IS AFTER THE JOURNAL REVIEW

Abstract

We present a long-term optical spectroscopic study of the post-AGB binary system 89 Herculis, with the aim to characterize the relationship between photospheric instabilities and dynamics in the close circumstellar environment of the system. This study is based on spectra acquired with the high-resolution Catania Astrophysical Observatory Spectropolarimeter and archive data, covering a time interval between 1978 and 2018. We find long-term changes in the radial velocity curve of the system, occurring mostly in amplitude, which correlate with the variability observed in the blue-shifted absorption component of the P Cygni like H$\alpha$ profile. Two possible scenarios are discussed. We also find strong splitting in the s-process elements of \ion{Ba}{ii} $6141.713$ \AA\ and $6496.898$ \AA\,lines, with short-term morphological variations. A Gaussian decomposition of such profiles allows us to distinguish four shell components, two expanding and two in-falling toward the central star, which are subject to the orbital motion of the system and are not affected by the long-term instabilities. Finally, we find that the numerous metal lines in emission could originate in regions of a structured circumbinary disk that have sizes proportional to the energy of the corresponding upper level transition $\rm E_{up}$. This study demonstrates the potential of long-term high-resolution spectroscopy in linking together the instability processes occurring during the late evolutionary stages of post-AGBs and the subsequent phase of PNe., Comment: 17 pages, 16 figures, accepted for publication in MNRAS

Abstract

The new European Union animal health law and its rule concerning brucellosis in cattle and buffaloes The authors examine the latest European Union (EU) rules concerning eradication and surveillance of brucellosis and animal infectious diseases of EU concern. The Italian rules concerning brucellosis in cattle and buffaloes Italy is included in the EU co-financed compulsory eradication and surveillance programmes for brucellosis in cattle and in buffaloes in the frame of the EU and the related Italian laws, which allowed reaching the Brucellosis Free status without vaccination (former "Officially Brucellosis Free - OBF" status) in the majority of the northern and middle Italian Regions and in some middle and southern Provinces included in Regions where the infection persists. Epidemiology of brucellosis in the EU and in Italy In the Italian Province of Caserta, the highest prevalence of brucellosis in buffaloes is reported; in 2017-2021, a total of 314 outbreaks occurred, in which 39,163 heads tested positive. Here, brucellosis is threatening not only human health and the widespread buffaloes breeding but also the important satellite activities concerning the Protected Designation of Origin (P.O.D.) cheese “Mozzarella di Bufala Campana". The authors also discuss the reemerged brucellosis in cattle in the Molise Region, which despite bordering the Province of Caserta, shows different hydrographic, orographic, and breeding characteristics. In Molise, the reemerged brucellosis had a very different epidemiological course, which allowed it to limit the adoption of One Health measures. The One Health approach to tackle brucellosis in buffaloes In order to tackle brucellosis in Campania Region and in its Province of Caserta, the One Health approach has been predisposed through strict control of animal health, human health, and the environment. The adopted model could be exportable to territories having similar characteristics.

Abstract

Atomic data are fundamental for plasma diagnostics in laboratory and astrophysics through spectroscopy. These data are extensively present in data bases for light elements, however incomplete for high-mass atoms. This paper presents the results of systematic spectroscopy of 17 elements with high Z , expected to be produced in kilonova events generated by neutron star mergers, whose spectral lines are not yet fully identified in stellar spectra and fusion devices. Experimental data are from échelle high-resolution (λ/Δλ = 60 000) spectroscopy of hollow cathode lamps obtained with the Catania Astrophysical Observatory Spectropolarimeter covering the 3700–10 000 Å range in a single exposure. A total of about 7700 spectral lines with energy level classification not previously listed in the NIST, Kurucz, and VALD data bases are here reported for neutral and singly ionized atomic transitions. For the spectral lines of any species, we report the measured wavelengths and their relative intensities. If possible, we also estimate the transition probabilities under the assumptions of optically thin emission and electric-dipole transitions. These are converted into oscillator strengths ready to be inserted in astrophysical data bases for spectral synthesis. [ABSTRACT FROM AUTHOR]

17. Menstrual changes after COVID-19 vaccine administration: a systematic review.

Author

SANTANGELO, O. E., PROVENZANO, S., GRIGIS, D., FERRARA, C., CEDRONE, F., and FIRENZE, A.

Abstract

OBJECTIVE: During the mass vaccination campaign for COVID-19, cases of menstrual cycle changes in women emerged, so it was thought that the COVID-19 vaccine could affect the menstrual cycle. Over time, these observations have become more frequent, which strengthens the idea. This systematic review aims to show changes in the menstrual cycle after COVID-19 vaccination. MATERIALS AND METHODS: This study was carried out following the guidelines of the Cochrane Collaboration and the Meta-analysis of Observational Studies in Epidemiology and the Preferred Reporting Items for Systematic Reviews and Meta-Analyzes. RESULTS: A suitable bibliography on PubMed/Medline and Scopus was searched by combining text, words, and titles of medical topics. After completing the search, a total of 42 articles were included in this systematic review. CONCLUSIONS: The COVID-19 vaccines may have an impact on the quality of life of women. The changes in the menstrual cycle tend to resolve within 2-3 months of vaccination and the symptoms are mild to moderate and tend to self-limit over time. [ABSTRACT FROM AUTHOR]

Abstract

In the scarce landscape of anodic materials, one of the most interesting is the family of MXenes: 2D materials with Mn+1XnTx stoichiometry, where M is a transition metal, X is carbon or nitrogen and T is the functionalization of the layers. However, such materials are obtained by etching the corresponding MAX phase precursor with HF; to prevent this hazardous operation, we studied thermally treated Sn-doped MAX phases directly as anodes both in lithium and sodium ion batteries (LIBs, SIBs). The Ti3Al(1-x)SnxC2 MAX phase samples with x = 0, 0.4, and 0.7 were synthesized via Spark Plasma Sintering (SPS). They were subjected to a thermal treatment at 600°C in air and studied as anodic materials in SIBs and LIBs by galvanostatic cycling with potential limitation (GCPL). The MAX phases have been characterized by X-ray and neutron diffraction (XRD, ND), thermal gravimetric analysis (TGA), CHNS, electron microscopies (SEM, TEM), and Raman spectroscopy. The electrochemical performances of the oxidized samples are noticeably better than the non-oxidized ones: for the NIBs, at 1 C the specific capacity is around 70-78 mAh/g, while for the non-oxidized samples it is around 10-16 mAh/g. The LIBs coins show a remarkably increasing capacity for a higher Sn content: it is 200 mAh/g for Sn0.4_Ox and 250 mAh/g for Sn0.7_Ox at 1 C. The structural analysis in agreement with the Raman analysis and the TEM electron diffraction evidenced the appearance of rutile and Ti-Sn mixed oxides in the thermally treated samples, and the TEM imaging showed the presence of such oxides as nanometric crystallites (diameter of ~20 nm) on the surface of the MAX phase. According to our TGA analysis and the literature, the presence of Sn lowers the oxidation resistance of the MAX phase, resulting in a lower oxidation temperature and a higher percentage of oxides, which is confirmed also by CHNS. Since the MAX phase is inert, the potential profiles from the GCPL suggest that for the LIBs the measured capacity is due to mixed mechanisms of intercalation, conversion, and alloying in the nanostructured oxide composite.

Abstract

Many ecological studies require long-term time series of high quality. Missing data may represent a serious problem since they can affect the reliability of measured variables in specific locations. To which extent and according to which methodology a gap in time series should be filled is a major research challenge. In this study, the time-series of meteorological data relative to 13 monitoring sites from the ICP-Forest network in Italy were analysed with the aim to define the minimum number of site-specific observations, which can be considered adequate for further analysis on forest resource management. Three main climatic variables were taken into account in the analysis: air temperature, relative humidity and total precipitation. By using an increasing proportion of available data, descriptive and inferential statistic methods were applied to evaluate the amount of variability along the period of analysis (1998-2013) and associated error of estimation at seasonal level. The relative importance of each factor accounted in our analysis (season, year, variable, plot, sampling proportion) was investigated fitting a Random Forest model on the results of the bootstrapping procedure. Air temperature was the variable with a marked seasonal profile and the easiest to be represented at monthly level on a specific time period. Humidity and precipitation were more stable across the analysed time period. Trends in precipitation showed that a high amount of variability could be detected only when > 80% of valid observations were available. Humidity showed an intermediate pattern, with an exponential increase in the amount of explained variability when using an increased proportion of sampled observations. Random Forest Regression models indicated sampling proportion (i.e., number of available observations) as an important factor for trend analysis of relative air humidity and precipitation. We conclude that monthly or seasonal statistics can be proficiently estimated for both air temperature and relative humidity with a proportion of missing values higher than 50%. Conversely, a reliable analysis of intra-seasonal or intra-monthly precipitation variability requires a much higher amount of observations. In the latter case gap filling represents the only feasible solution.

Abstract

The cost of suppressing fires is known to be highly significant and increasing over time as a result of the indirect effects of climate change and rising human impacts. Their quantification is an essential component of an environmental accounting system, capable of providing updated information for policy design and implementation. The goal of this study was to provide an overview of the state-of-art of international literature on wildfire suppression costs. To this aim, a systematic literature review was carried out revealing that the largest amount of empirical data on suppression costs and related measures derived from North American case studies. Conversely, information on direct wildfire suppression cost categories is usually incomplete or missing throughout Europe, especially in fire-prone Mediterranean countries, even though these areas have been, and continue to be, severely impacted by wildfires, underlining the need to update research in this field, thereby supporting cost-effective fire management plans.
