Per Gianni cinque parole di contatto albanese-calabrese
The article consists in five loanwords that show strong interlinguistic contact between Albanian and Romance speakers over the centuries in Calabria. From the ethnolinguistic point of view they are consistent with Gianni Belluscio's interests. Albanian transmits Albanian and Slav items, even Turkish and Persian ones, picked up long ago in the Byzantine Empire
Evidence for an X-ray Emitting Galactic Bulge: Shadows Cast by Distant Molecular Gas
A mosaic of 7 ROSAT PSPC pointed observations in the direction of (l,b ~ 10,0
deg) reveals deep X-ray shadows in the 0.5-2.0 keV band cast by dense molecular
gas. The comparison between the observed on-cloud and off-cloud X-ray fluxes
indicates that ~43% of the diffuse X-ray background in this direction in both
the 3/4 keV and 1.5 keV bands originates behind the molecular gas, which is
located at 2-4 kpc from the Sun. Given the short mean free path of X-rays in
the 3/4 keV band in the Galactic plane (~1 kpc assuming an average space
density of 1 cm^-3), this large percentage of the observed flux which
originates beyond the molecular gas most likely indicates a strong enhancement
in the distribution of X-ray emitting gas in the Galactic center region,
possibly associated with a Galactic X-ray bulge.Comment: 16 pages LaTex, 2 figures. Accepted for the publication in

The ROSAT North Ecliptic Pole Survey: The X-ray Catalog
The sky around the North Ecliptic Pole (NEP), at (2000) =
18, (2000) = +66\degr33\arcmin39\arcsec, has the deepest
exposure of the entire {\it ROSAT} All - Sky Survey (RASS). The NEP is an
undistinguished region of moderate Galactic latitude, b=29\fdg8, and hence
suitable for compiling statistical samples of both galactic and extragalactic
objects. We have made such a compilation in the 80.6 deg region surrounding
the NEP. Our sample fully exploits the properties of the RASS, since the only
criteria for inclusion are source position and significance, and yields the
deepest large solid angle contiguous sample of X-ray sources to date. We find
442 unique sources above a flux limit in the 0.5--2.0 keV band. In this paper we present the
X-ray properties of these sources as determined from the RASS. These include
positions, fluxes, spectral information in the form of hardness ratios, and
angular sizes. Since we have performed a comprehensive optical identification
program we also present the average X-ray properties of classes of objects
typical of the X-ray sky at these flux levels. We discuss the use of the RASS
to find clusters of galaxies based on their X-ray properties alone.Comment: 48 pages, 13 figures, accepted for ApJ Supp 162, 2006 (February

What's in a Name? Shifting Identities of Traditional Organized Crime in Canada in the Transnational Fight against the Calabrian ‘Ndrangheta
The Italian antimafia authorities have warned Canadian law enforcement about the risks and the growing concerns for the infiltration of clans of the Calabrian mafia, known as ‘ndrangheta, in Eastern Canada. The alarm linked to the rise of the ‘ndrangheta challenges the paradigms of traditional organized crime in Canada, because the ‘ndrangheta is presented as traditional but also innovative and more pervasive than other mafia-type groups. Through access to confidential investigations and interviews to key specialist law enforcement teams in Toronto and Montreal, this article investigates today's institutional perception of mafia – the ‘ndrangheta in particular – in Canada when compared to Italian conceptualizations. I will argue that the changes in narratives in Canada can be read in relation to changes in the Italian identity in the country, moving towards regionalization and specialist knowledge of ethnic differences
Whole-genome sequencing reveals host factors underlying critical COVID-19
Critical COVID-19 is caused by immune-mediated inflammatory lung injury. Host genetic variation influences the development of illness requiring critical care1 or hospitalization2–4 after infection with SARS-CoV-2. The GenOMICC (Genetics of Mortality in Critical Care) study enables the comparison of genomes from individuals who are critically ill with those of population controls to find underlying disease mechanisms. Here we use whole-genome sequencing in 7,491 critically ill individuals compared with 48,400 controls to discover and replicate 23 independent variants that significantly predispose to critical COVID-19. We identify 16 new independent associations, including variants within genes that are involved in interferon signalling (IL10RB and PLSCR1), leucocyte differentiation (BCL11A) and blood-type antigen secretor status (FUT2). Using transcriptome-wide association and colocalization to infer the effect of gene expression on disease severity, we find evidence that implicates multiple genes—including reduced expression of a membrane flippase (ATP11A), and increased expression of a mucin (MUC1)—in critical disease. Mendelian randomization provides evidence in support of causal roles for myeloid cell adhesion molecules (SELE, ICAM5 and CD209) and the coagulation factor F8, all of which are potentially druggable targets. Our results are broadly consistent with a multi-component model of COVID-19 pathophysiology, in which at least two distinct mechanisms can predispose to life-threatening disease: failure to control viral replication; or an enhanced tendency towards pulmonary inflammation and intravascular coagulation. We show that comparison between cases of critical illness and population controls is highly efficient for the detection of therapeutically relevant mechanisms of disease

Ancora ‘s impura’ (in cauda veritas)
Sebbene la nozione di ‘s impura’ (SI) – /s/ preconsonantica, come in pasta o scafo – sia familiare a generazioni di discenti italiani, la sua attribuzione è oscura. Si può immaginare che un lontano grammatico abbia notato che /s/ preconsonantica in inizio di parola manifestasse comportamenti anomali rispetto a quella prevocalica, con particolare riferimento a processi quali la selezione dei determinanti, l’inibizione del troncamento e la prostesi dopo clitici terminanti in consonante. Nonostante ciò, il presunto grammatico (o altri successivi) concluse che i nessi con ‘s impura’ fossero tautosillabici, anche in interno di parola, basandosi su un criterio ragionevole: ‘se un nesso può stare in inizio di parola, allora deve stare in inizio di sillaba’. Nella pratica dell’andare a capo di riga, di conseguenza, generazioni di scolari italiani sono stati istruiti a trattare questi nessi come quelli indiscutibilmente tautosillabici.
Un numero impressionante di studi di diversa impostazione si è accumulato nel tempo per studiare le peculiari caratteristiche di SI, ma senza raggiungere un consenso. Lo scopo di questo lavoro è di riesaminare le prove che sono state portate in favore dell’eterosillabicità di SI e di presentarne di nuove in favore dell’ipotesi che SI sia sempre scandita come coda
