Weighted estimates for integral operators on local BMO type spaces
(2015)
We prove the weighted boundedness for a family of integral operators Tα on Lebesgue spaces and local BMO type spaces. To this end we show that Tα can be controlled by the Calder ́on operator and a local maximal operator. ...
Directed search for gravitational waves from Scorpius X-1 with initial LIGO data
(2015)
We present results of a search for continuously emitted gravitational radiation, directed at the brightest low-mass x-ray binary, Scorpius X-1. Our semicoherent analysis covers 10 days of LIGO S5 data ranging from 50–550 ...
Experimental determination of multiple ionization cross sections in Si by electron impact
(2015)
The thin sample method is often used to experimentally determine ionization cross sections, specially when focusing on the low overvoltage region. The simplicity of the formalism involved in this method is very appealing, ...
Dynamic heterogeneity in the monoclinic phase of CCl4
(2016)
Carbon tetrachloride (CCl4) is one of the simplest compounds having a translationally stable monoclinic phase while exhibiting a rich rotational dynamics below 226 K. Recent nuclear quadrupolar resonance (NQR) experiments ...
Stopping power of palladium for protons in the energy range 0.300-3.100 MeV
(2013)
The stopping power of palladium for protons has been measured using the transmission method with an overall uncertainty of around 5% over the energy range Ep=(0.300–3.100) MeV. These stopping power data are then compared ...
Invariants of complex structures on nilmanifolds
(2015)
Let (N, J) be a simply connected 2n-dimensional nilpotent Lie group endowed with an invariant complex structure. We define a left invariant Riemannian metric on N compatible with J to be minimal, if it minimizes the norm ...
Calibration method for confocal X-ray microanalysis with polychromatic excitation
(2015)
To apply the fundamental parameters method at the confocal setup the knowledge of the sensitivity of the spectrometer is required which depends on the characteristics of two X-ray lenses: one in the excitation channel and ...
Properties of NiMnGa alloys ultra rapidly solidified by suction casting
(2015)
Ni2MnGa alloys are obtained by suction casting in water chilled cylindrical copper moulds 50 mm long and 1-4 mm in diameter; the microstructure and the magnetic properties are then investigated as functions of the cylinder ...
On structural completeness versus almost structural completeness problem : a discriminator varieties case study
(2015)
We study the following problem: determine which almost structurally complete quasivarieties are structurally complete. We propose a general solution to this problem and then a solution in the semisimple case. As a consequence, ...
Critical exponents and scaling invariance in the absence of a critical point
(2016)
The paramagnetic-to-ferromagnetic phase transition is classified as a critical phenomenon due to the power-law behaviour shown by thermodynamic observables when the Curie point is approached. Here we report the observation ...
