Ionospheric Narrowband and Wideband HF Soundings for Communications Purposes: A Review
(MDPI, 2020-04)
High Frequency (HF) communications through ionospheric reflection is a widely usedtechnique specifically for maritime, aeronautical, and emergency services communication withremote areas due ...
Small is big in ICT: The impact of R&D on productivity
(Elsevier, 2019-07)
We examine the contribution of R&D to firm productivity in a large panel of European firms and study its variation with the age, size, and sub-sector of firms. We find that R&D capital in ICT firms has ...
Entre foscors i clarors. La ‘mirada’ com a ‘exercici filosòfic’ a la Caverna de Plató
(Universitat de Barcelona, 2012)
Aquest estudi pretén situar dins d’un context filològic, cultural i filosòfic l’«itinerari de la mirada» que llegim en la «narració de la Caverna» del llibre VII de La República de Plató. Amb aquest ...
Hierarchical Classification of Environmental Noise Sources by Considering the Acoustic Signature of Vehicle Pass-bys
(Committee on Acoustics PAS, PAS Institute of Fundamental Technological Research, Polish Acoustical Society, 2012-12)
This work is focused on the automatic recognition of environmental noise sources that affect humans’ health and quality of life, namely industrial, aircraft, railway and road traffic. However, the ...
Measurement of CP violation and constraints on the CKM angle γ in B±→DK±with D→K0S π+π− decays
(Elsevier, 2014-11)
A model-dependent amplitude analysis of B± → DK± with D → KS0π+π− decays is performed using proton–proton collision data, corresponding to an integrated luminosity of 1fb−1, recorded by LHCb at a ...
Search for CP violation in D+ → K−K+π+ decays
(American Physical Society, 2011-12-28)
A model-independent search for direct CP violation in the Cabibbo-suppressed decay D+→K−K+π+ in a sample of approximately 370 000 decays is carried out. The data were collected by the LHCb experiment ...
Measurement of the branching fractions of the decays B0s→¯¯¯D0K−π+ and B0→¯¯¯D0K+π−
(American Physical Society, 2013-06-20)
The first observation of the decay B0s→¯¯¯D0K−π+ is reported. The analysis is based on a data sample, corresponding to an integrated luminosity of 1.0 fb−1 of pp collisions, collected with the LHCb ...
Precision measurement of the B+c meson mass
(Springer, 2020-07)
A precision measurement of the B+c meson mass is performed using proton- proton collision data collected with the LHCb experiment at centre-of-mass energies of 7, 8 and 13 TeV, corresponding to a total ...
Measurement of the B0s−B¯0s oscillation frequency Δms in B0s→D−s(3)π decays
(Elsevier, 2012-03-19)
The B0s–B0soscillation frequency msis measured with 36 pb−1of data collected inppcollisions at √s=7 TeV by the LHCb experiment at the Large Hadron Collider. A total of 1381B0s→D−sπ+andB0s→D−sπ+π−π+signal ...
Measurements of the branching fractions and CP asymmetries of B± → J/ψ π± and B± → ψ(2S) π± decays
(American Physical Society, 2012-05-07)
A study of B±→J/ψπ± and B±→ψ(2S)π± decays is performed with data corresponding to 0.37 fb−1 of proton-proton collisions at √s=7 TeV. Their branching fractions are found to be B(B±→J/ψπ±)=(3.88±0.11± ...
