ATLAS measurements of the properties of jets for boosted particle searches
2012
Measurements are presented of the properties of high transverse momentum jets, produced in proton-proton collisions at a center-of-mass energy of √s=7 TeV. The data correspond to an integrated luminosity of 35 pb−1 and were collected with the ATLAS detector in 2010. Jet mass, width, eccentricity, planar flow and angularity are measured for jets reconstructed using the anti-kt algorithm with distance parameters R=0.6 and 1.0, with transverse momentum pT>300 GeV and pseudorapidity |η|<2. The measurements are compared to the expectations of Monte Carlo generators that match leading-logarithmic parton showers to leading-order, or next-to-leading-order, matrix elements. The generators describ…
Search for excited electrons and muons in root s=8 TeV proton-proton collisions with the ATLAS detector
2013
The ATLAS detector at the Large Hadron Collider is used to search for excited electrons and excited muons in the channel pp → ℓℓ* → ℓℓγ, assuming that excited leptons are produced via contact interactions. The analysis is based on 13 fb[superscript −1] of pp collisions at a centre-of-mass energy of 8 TeV. No evidence for excited leptons is found, and a limit is set at the 95% credibility level on the cross section times branching ratio as a function of the excited-lepton mass m[subscript ℓ*]. For m[subscript ℓ*] ≥ 0.8 TeV, the respective upper limits on σB(ℓ* → ℓγ) are 0.75 and 0.90 fb for the e* and μ* searches. Limits on σB are converted into lower bounds on the compositeness scale Λ. In …
Search for strong gravity signatures in same-sign dimuon final states using the ATLAS detector at the LHC
2012
A search for microscopic black holes has been performed in a same-sign dimuon final state using 1.3 fb[superscript −1] of proton–proton collision data collected with the ATLAS detector at a centre of mass energy of 7 TeV at the CERN Large Hadron Collider. The data are found to be consistent with the expectation from the Standard Model and the results are used to derive exclusion contours in the context of a low scale gravity model.

POSSIBILITIES OF USING DIALECT ATLASES IN THE ACQUISITION OF LATVIAN LANGUAGE
2020
The creation of a modern lesson increasingly uses open data, a variety of digital resources, electronic teaching tools etc. In addition to books, electronic teaching tools, information resources, etc., come into the training process as a way to portray linguistic information and the writers' creative thought. One of the resources that can be successfully exploited in promoting the growth of a fully developed and skilled pupil, as well as in-depth learning of the Latvian language, is dialect atlases. The aim of the research was to understand the functionality and effectiveness of the dialect atlases in lear ning lexicology and dialectology. The study combined the descriptive method and conte…
Sulla distribuzione di alcuni Uccelli nidificanti in provincia di Trapani (Sicilia)
2019
A distanza di 10 anni dalla pubblicazione dell’ultimo Atlante dei Vertebrati di Sicilia si rivede la distribuzione delle specie nidificanti, alla luce di nuovi dati raccolti, al fine di aggiornare il loro status. Nel presente lavoro vengono elencate solo le specie di uccelli, rilevate in questi ultimi anni, non segnalate come nidificanti nei precedenti Atlanti e le specie già trattate ma che hanno riportato delle variazioni significative nella loro distribuzione. Updating of the distribution of some breeding birds in the province of Trapani (Sicily). This work deals with the distribution of the breeding birds in the province of Trapani (western Sicily); here are provided and updated the sta…

Sensory neuropathy with bone destruction due to a mutation in the membrane-shaping atlastin GTPase 3.
2014
Many neurodegenerative disorders present with sensory loss. In the group of hereditary sensory and autonomic neuropathies loss of nociception is one of the disease hallmarks. To determine underlying factors of sensory neurodegeneration we performed whole-exome sequencing in affected individuals with the disorder. In a family with sensory neuropathy with loss of pain perception and destruction of the pedal skeleton we report a missense mutation in a highly conserved amino acid residue of atlastin GTPase 3 (ATL3), an endoplasmic reticulum-shaping GTPase. The same mutation (p.Tyr192Cys) was identified in a second family with similar clinical outcome by screening a large cohort of 115 patients …
