We present a parton-level study of electro-weak production of vector-boson pairs at the Large Hadron Collider, establishing the sensitivity to a set of dimension-six operators in the ...Standard Model Effective Field Theory (SMEFT). Different final states are statistically combined, and we discuss how the orthogonality and interdependence of different analyses must be considered to obtain the most stringent constraints. The main novelties of our study are the inclusion of SMEFT effects in non-resonant diagrams and in irreducible QCD backgrounds, and an exhaustive template analysis of optimal observables for each operator and process considered. We also assess for the first time the sensitivity of vector-boson-scattering searches in semileptonic final states.
Abstract
We present the average C
ii
158
μ
m emission line sizes of UV-bright star-forming galaxies at
z
∼ 7. Our results are derived from a stacking analysis of C
ii
158
μ
m emission lines and ...dust continua observed by the Atacama Large Millimeter/submillimeter Array (ALMA), taking advantage of the large program Reionization Era Bright Emission Line Survey. We find that the average C
ii
emission at
z
∼ 7 has an effective radius
r
e
of 2.2 ± 0.2 kpc. It is ≳2× larger than the dust continuum and the rest-frame UV emission, in agreement with recently reported measurements for
z
≲ 6 galaxies. Additionally, we compared the average C
ii
size with 4 <
z
< 6 galaxies observed by the ALMA Large Program to INvestigate C
ii
at Early times (ALPINE). By analyzing C
ii
sizes of 4 <
z
< 6 galaxies in two redshift bins, we find an average C
ii
size of
r
e
= 2.2 ± 0.2 kpc and
r
e
= 2.5 ± 0.2 kpc for
z
∼ 5.5 and
z
∼ 4.5 galaxies, respectively. These measurements show that star-forming galaxies, on average, show no evolution in the size of the C
ii
158
μ
m emitting regions at redshift between
z
∼ 7 and
z
∼ 4. This finding suggests that the star-forming galaxies could be morphologically dominated by gas over a wide redshift range.
Nowadays, the use of Ladle Furnace Steel (LFS) is spreading in the field of asphalt pavements. LFS are generally used as filler in Hot Mix Asphalt (HMA). The main purpose of this study is to analyse ...and understand the role of LFS characteristics on the possible stiffening effects of asphalt materials. Different characteristics of LFSs, such as particle size distribution, specific surface area (SSA), chemical and mineralogical properties were evaluated in addition to the performance of HMAs on different scales (mastic and HMA). One type of LFS, one standard limestone and their blends were mixed with two different asphalt binders, one pure and one 3.5% Styrene–Butadiene–Styrene (SBS) cross-linked modified. The results showed no significant correlations between the physical properties of the LFS and the performance levels of the HMAs, but it was pointed out that the LFS content in the filler blend should not exceed 30%.
•No-significant stiffening effects are highlighted when the LFSs are used as filler.•The morphological and particle size analysis show striking differences between limestone and LFS.•No-significant correlations are highlighted among LFSs’ physical properties and HMAs’ performance levels.
In-situ shattered rocks are often associated with seismogenic fault zones, but their mechanism of formation is still matter of debate, partly because of the limited number of field studies. Here we ...describe the characteristics of in-situ shattered rocks distribution along the NW-SE-striking seismogenic Monte Marine Fault (MMF) in the Italian Central Apennines. In the studied area, the MMF cuts through Mesozoic carbonates, is exhumed from <3 km depth and consists of two >5 km-long major hard-linked segments with normal kinematics. The linkage between the two fault segments occurs along a ∼2 km-long step-over zone with E-W trending faults and oblique-slip kinematics. To the northwest, fault-related shear deformation is localized in a ∼5 m-thick cataclastic fault core and off-fault deformation is dominated by in-situ shattered rocks up to ∼40 m-thick. Instead, in the step-over zone to the southeast, the in-situ shattered rocks are up to ∼500 m thick, particularly where MMF crosscuts older low-angle thrust faults.
We integrated detailed field structural surveys with microstructural and grain size distribution analyses of the fault rocks to assess the mechanism of (1) formation of in-situ shattered rocks and, (2) progressive localization of shear deformation along the MMF. The obtained results, after the viability of several formation mechanisms (mechanical models) have been reviewed, support the hypothesis that the formation of in-situ shattered rocks was associated with the propagation of (multiple) seismic ruptures (mainshocks and aftershock sequences) within a mechanically heterogeneous fault zone. Heterogeneity is due to the occurrence of preexisting damage related to previous earthquakes, but also inherited from the older low-angle thrust faults. Therefore, we suggest that the origin of these shattered rocks is more compatible with seismic related processes than only with quasi-static fault growth models. On the other hand, the cataclastic fault core derived from the progressive accommodation of shear deformation within the in-situ shattered rock volumes during several seismic cycles. We conclude that the large volumes of in-situ shattered rocks are the result of seismic-related dissipative processes in a geometrically and mechanically heterogeneous fault zone. In this scenario, large volumes of in-situ shattered rocks are compliant low velocity zones which can influence the propagation of earthquake ruptures.
•Loose mosaic breccias with thickness ∼50–500 m are developed along the Monte Marine Fault.•Mosaic breccias are interposed between the fault core and the fractured damage zone.•They have mean clast diameters of ∼1–10 mm and fractal dimension of D∼2.5, lower than cataclasites with D∼2.7–3•Large volumes of breccias are found at fault intersections with previous thrust faults and fault overstep areas.•Breccias are in-situ shattered rocks produced during a seismic-related dissipative process.
Allogeneic bone marrow transplantation (BMT) from a genotypically identical family donor is an accepted therapeutic option for homozygous beta-thalassemia. However, only a minority of patients have ...access to this curative procedure. The aim of this study is to explore the feasibility of matched unrelated transplants in thalassemia and the possibility of reducing the risk of immunologic complications through careful selection of donor/recipient pairs. Since November 1992, 32 patients (age range, 2-28 years) have been enrolled. There were 4 patients assigned to risk-class I, 11 to risk-class II, and 17 to risk-class III of the Pesaro classification. Extended haplotype analysis and family segregation studies were employed for identification of suitable donors. Of the 32 donor/recipient pairs, 24 were identical for HLA-A, B, C, DRB1, DRB3, DRB4, DRB5, DQA1, and DQB1 loci; 7 pairs were identical for 2 extended haplotypes, and 15 pairs shared one extended haplotype. Grade II-IV acute graft-versus-host disease (GVHD) developed in 11 cases (41%) and chronic GVHD in 6 (25%) out of 24 patients at risk. There are 22 patients (69%) who are alive and transfusion-independent after a median follow-up of 30 months (range, 7-109 months). There were 6 patients (19%) who engrafted and subsequently died from transplant-related complications. In 4 cases (12.5%) graft rejection was observed within 30 days and it was followed by autologous reconstitution. Out of 22 patients with a donor identical for at least one extended haplotype, there are 19 who survived, 17 of them being transfusion-independent. Among the 10 recipients who did not share any extended haplotype with the donor, only 5 are alive without thalassemia and 3 patients died. Of the 6 patients who died, 5 belonged to risk-class III and only 1 to risk-class II. BMT from well-selected unrelated donors may offer results comparable to those obtained in transplantations using HLA-identical family donors, especially for patients with lesser iron overload.
Constraining the strength of gas turbulence in protoplanetary discs is an open problem that has relevant implications for the physics of gas accretion and planet formation. In this work, we gauge the ...amount of turbulence in 6 of the discs observed in the DSHARP programme by indirectly measuring the vertical distribution of their dust component. We employ the differences in the gap contrasts observed along the major and the minor axes due to projection effects, and build a radiative transfer model to reproduce these features for different values of the dust scale heights. We find that (a) the scale heights that yield a better agreement with data are generally low (\(\lesssim 4\) AU at a radial distance of \(100\) AU), and in almost all cases we are only able to place upper limits on their exact values; these conclusions imply (assuming an average Stokes number of \(\approx10^{-2}\)) low turbulence levels of \(\alpha_{\rm SS}\lesssim10^{-3}-10^{-4}\); (b) for the 9 other systems we considered out of the DSHARP sample, our method yields no significant constraints on the disc vertical structure; we conclude that this is because these discs have either a low inclination or gaps that are not deep enough. Based on our analysis we provide an empirical criterion to assess whether a given disc is suitable to measure the vertical scale height.
HLA-A, B, Cw, DR and DQ antigens were serologically determined in 105 patients suffering from lichen planus (LP). Of these patients, 87 had idiopathic LP and 18 had secondary LP. In the first group, ...43 had cutaneous LP without mucosal lesions, 17 had cutaneous LP with mucosal lesions and 27 had purely mucosal LP. No HLA antigen was found to be significantly associated with secondary LP or with mucosal idiopathic LP. In cutaneous idiopathic LP with or without mucosal lesions, the HLA-DR1 and DQ1 antigen frequency was significantly increased, and that of HLA-DQ3 significantly decreased. Among the HLA-DR1 cutaneous idiopathic LP patients, 78.5% carried the DRB1*0101 allele, and 21.4% the DRB1*0102 allele, compared with 35.7 and 67.8%, respectively, of the HLA-DR1 controls. Our data demonstrate that idiopathic LP is influenced by HLA-associated genetic susceptibility and resistance factors not involved in secondary LP, and that cutaneous idiopathic LP is a genetically and therefore pathogenetically different condition from purely mucosal idiopathic LP.
We present the average CII $158\,\rm{\mu m}$ emission line sizes of
UV-bright star-forming galaxies at $z\sim7$. Our results are derived from a
stacking analysis of CII $158\,\rm{\mu m}$ emission ...lines and dust continua
observed by ALMA, taking advantage of the large program Reionization Era Bright
Emission Line Survey (REBELS). We find that the average CII emission at
$z\sim7$ has an effective radius $r_e$ of $2.2\pm0.2\,\rm{kpc}$. It is
$\gtrsim2\times$ larger than the dust continuum and the rest-frame UV emission,
in agreement with recently reported measurements for $z\lesssim6$ galaxies.
Additionally, we compared the average CII size with $4<z<6$ galaxies observed
by the ALMA Large Program to INvestigate CII at Early times (ALPINE). By
analysing CII sizes of $4<z<6$ galaxies in two redshift bins, we find an
average CII size of $r_{\rm e}=2.2\pm0.2\,\rm{kpc}$ and $r_{\rm
e}=2.5\pm0.2\,\rm{kpc}$ for $z\sim5.5$ and $z\sim4.5$ galaxies, respectively.
These measurements show that star-forming galaxies, on average, show no
evolution in the size of the CII $158\,{\rm \mu m}$ emitting regions at
redshift between $z\sim7$ and $z\sim4$. This finding suggest that the
star-forming galaxies could be morphologically dominated by gas over a wide
redshift range.
