O egregie grammatice: the vocative problems of Latin words ending in -ius
© The Classical Association 2000A long-lasting and sometimes acrimonious debate over the correct vocative form of second-declension Latin words in -ius began more than 800 years ago. For the past century most classicists have considered the matter to be settled, and little discussion on the subject has taken place. Yet the century-old conclusions we now so unthinkingly accept are based on very little evidence and are internally inconsistent in some of their details. The past hundred years have provided us not only with more Latin to work with, better tools for search and analysis, and a more complete knowledge of the history of the Latin language, but also with a new understanding and respect for the ancient grammarians and their views on the structure of their language. It is time to re-examine the ancient and modern views on the vocative of -ius words, to see whether any viable conclusions can be drawn and whether the ancient grammarians may have more to contribute than our predecessors believed
The Northern Cross Fast Radio Burst project -- III. The FRB-magnetar connection in a sample of nearby galaxies
Fast radio bursts (FRBs) are millisecond radio transients observed at
cosmological distances. The nature of their progenitors is still a matter of
debate, although magnetars are invoked by most models. The proposed
FRB-magnetar connection was strengthened by the discovery of an FRB-like event
from the Galactic magnetar SGR J1935+2154. In this work, we aim to investigate
how prevalent magnetars such as SGR J1935+2154 are within FRB progenitors. We
carried out an FRB search in a sample of seven nearby (< 12 Mpc) galaxies with
the Northern Cross radio telescope for a total of 692 h. We detected one 1.8 ms
burst in the direction of M101 with a fluence of Jy ms. Its
dispersion measure of 303 pc cm places it most-likely beyond M101.
Considering that no significant detection comes indisputably from the selected
galaxies, we place a 38 yr upper limit on the total burst rate (i.e.
including the whole sample) at the 95\% confidence level. This upper limit
constrains the event rate per magnetar
magnetar yr or, if combined with literature observations of a
similar sample of nearby galaxies, it yields a joint constraint of
magnetar yr. We also provide the first
constraints on the expected rate of FRBs hypothetically originating from
ultraluminous X-ray (ULX) sources, since some of the galaxies observed during
our observational campaign host confirmed ULXs. We obtain yr per
ULX for the total sample of galaxies observed. Our results indicate that bursts
with energies erg from magnetars like SGR J1935+2154 appear more
rarely compared to previous observations and further disfavour them as unique
progenitors for the cosmological FRB population, leaving more space open to the
contribution from a population of more exotic magnetars, not born via
core-collapsed supernovae.Comment: 9 pages, 4 figures, published in A&
The Northern Cross Fast Radio Burst project: III. The FRB-magnetar connection in a sample of nearby galaxies
Context. Fast radio bursts (FRBs) are millisecond radio transients observed at cosmological distances. The nature of their progenitors is still a matter of debate, although magnetars are invoked by most models. The proposed FRB-magnetar connection was strengthened by the discovery of an FRB-like event from the Galactic magnetar SGR J1935+2154.
Aims: In this work we aim to investigate how prevalent magnetars such as SGR J1935+2154 are within FRB progenitors.
Methods: To this end, we carried out an FRB search in a sample of seven nearby (< 12 Mpc) galaxies with the Northern Cross Radio Telescope for a total of 692 h.
Results: We detected one 1.8 ms burst in the direction of M 101 with a fluence of 58 ± 5 Jy ms. Its dispersion measure of 303 pc cm−3 places it most likely beyond M 101. Considering that no significant detection comes indisputably from the selected galaxies, we place a 38 yr−1 upper limit on the total burst rate (i.e. including the whole sample) at the 95% confidence level. This upper limit constrains the event rate per magnetar to λmag < 0.42 magnetar−1 yr−1 or, if combined with literature observations of a similar sample of nearby galaxies, it yields a joint constraint of λmag < 0.25 magnetar−1 yr−1. We also provide the first constraints on the expected rate of FRBs hypothetically originating from ultra-luminous X-ray (ULX) sources, since some of the galaxies observed during our observational campaign host confirmed ULXs. We obtain < 13 yr−1 per ULX for the total sample of galaxies observed.
Conclusions: Our results indicate that bursts with energies E > 1034 erg from magnetars such as SGR J1935+2154 appear more rarely compared to previous observations and further disfavour them as unique progenitors for the cosmological FRB population. This provides support to the idea that there is a greater contribution from a population of more exotic magnetars not born via core-collapsed supernovae
Case Report: Invasive Fungal Infection and Daratumumab: A Case Series and Review of Literature
Life expectancy of multiple myeloma (MM) patients has improved in last years due to the advent of anti-CD38 monoclonal antibodies in combination with immunomodulators and proteasome inhibitors. However, morbidity and mortality related to infections remain high and represent a major concern. This paper describes the “real life” risk of invasive fungal infections (IFI) in patients treated with daratumumab-based therapy and reviews the relevant literature. In a series of 75 patients we only observed three cases of fungal pneumonia. Unfortunately, the early signs and symptoms were not specific for fungal infection. Diagnostic imaging, microbiology and patient history, especially previous therapies, are critical in the decision to start antifungal treatment. Recognising the subgroup of MM patients with high risk of IFI can increase the rate of diagnosis, adequate treatment and MM-treatment recovery
The Northern Cross Fast Radio Burst project - II. Monitoring of repeating FRB 20180916B, 20181030A, 20200120E and 20201124A
In this work we report the results of a nineteen-month Fast Radio Burst
observational campaign carried out with the North-South arm of the Medicina
Northern Cross radio telescope at 408~MHz in which we monitored four repeating
sources: FRB20180916B, FRB20181030A, FRB20200120E and FRB20201124A. We present
the current state of the instrument and the detection and characterisation of
three bursts from FRB20180916B. Given our observing time, our detections are
consistent with the event number we expect from the known burst rate ( above our 10, 38~Jy~ms detection threshold) in the 5.2 day active
window of the source, further confirming the source periodicity. We detect no
bursts from the other sources. We turn this result into a 95\% confidence level
lower limit on the slope of the differential fluence distribution to
be and for FRB20181030A and FRB20200120E
respectively. Given the known rate for FRB20201124A, we expect
bursts from our campaign, consistent with our non-detection.Comment: MNRAS Accepted, 10 pages, 6 figure
Status Report of the DPHEP Study Group: Towards a Global Effort for Sustainable Data Preservation in High Energy Physics
Data from high-energy physics (HEP) experiments are collected with
significant financial and human effort and are mostly unique. An
inter-experimental study group on HEP data preservation and long-term analysis
was convened as a panel of the International Committee for Future Accelerators
(ICFA). The group was formed by large collider-based experiments and
investigated the technical and organisational aspects of HEP data preservation.
An intermediate report was released in November 2009 addressing the general
issues of data preservation in HEP. This paper includes and extends the
intermediate report. It provides an analysis of the research case for data
preservation and a detailed description of the various projects at experiment,
laboratory and international levels. In addition, the paper provides a concrete
proposal for an international organisation in charge of the data management and
policies in high-energy physics
Measurement of the cross-section and charge asymmetry of bosons produced in proton-proton collisions at TeV with the ATLAS detector
This paper presents measurements of the and cross-sections and the associated charge asymmetry as a
function of the absolute pseudorapidity of the decay muon. The data were
collected in proton--proton collisions at a centre-of-mass energy of 8 TeV with
the ATLAS experiment at the LHC and correspond to a total integrated luminosity
of 20.2~\mbox{fb^{-1}}. The precision of the cross-section measurements
varies between 0.8% to 1.5% as a function of the pseudorapidity, excluding the
1.9% uncertainty on the integrated luminosity. The charge asymmetry is measured
with an uncertainty between 0.002 and 0.003. The results are compared with
predictions based on next-to-next-to-leading-order calculations with various
parton distribution functions and have the sensitivity to discriminate between
them.Comment: 38 pages in total, author list starting page 22, 5 figures, 4 tables,

Search for new phenomena in final states with an energetic jet and large missing transverse momentum in pp collisions at √ s = 8 TeV with the ATLAS detector
Results of a search for new phenomena in final states with an energetic jet and large missing transverse momentum are reported. The search uses 20.3 fb−1 of √ s = 8 TeV data collected in 2012 with the ATLAS detector at the LHC. Events are required to have at least one jet with pT > 120 GeV and no leptons. Nine signal regions are considered with increasing missing transverse momentum requirements between Emiss T > 150 GeV and Emiss T > 700 GeV. Good agreement is observed between the number of events in data and Standard Model expectations. The results are translated into exclusion limits on models with either large extra spatial dimensions, pair production of weakly interacting dark matter candidates, or production of very light gravitinos in a gauge-mediated supersymmetric model. In addition, limits on the production of an invisibly decaying Higgs-like boson leading to similar topologies in the final state are presente
