Recently a two-step process has been proposed for the double-pionic fusion to deuterium $pn (I=0) \to d\pi^+\pi^-$. Its calculation is solely based on total cross section data two sequential single-pion production steps (I=0)\to pp\pi^-$ followed by $pp d\pi^+$. Though this was aimed explain dibaryon resonance $d^*(2380)$ peak in fusion, we demonstrate that not case. It rather fits possible bro...
the indian riverine buffaloes are more susceptible to variations in the environment. these variations affect seminal plasma proteins, which in turn affect fertility. this study was conducted to evaluate variations in the indian bubalus bubalis seminal plasma protein profile using two-dimensional polyacrylamide gel electrophoresis (2d-page) during winter and summer seasons, and its relation with...
We aimed to measure the prevalence of physical inactivity (PI) during leisure time and to identify variables associated with it in a southern Brazilian adult population. A population-based cross-sectional study was carried out, covering a multiple-stage sample of 1,968 subjects aged 20-69 years. Weekly participation in leisure-time physical activity was addressed. For each activity, energy expe...
High resolution angle-resolved photoemission measurements on an underdoped (La(2-x)Srx)CuO4 system show that, at energies below 70 meV, the quasiparticle peak is well defined around the (pi/2,pi/2) nodal region and disappears rather abruptly when the momentum is changed from the nodal point to the (pi,0) antinodal point along the underlying "Fermi surface." It indicates that there is an extra l...
The branching fraction $\mathcal{B}(B^0 \to D^{*-}\tau^+\nu_{\tau})$ is measured relative to that of the normalisation mode $B^0 D^{*-}\pi^+\pi^-\pi^+$ using hadronic $\tau^+ \pi^+\pi^-\pi^+(\pi^0)\bar{\nu}_{\tau}$ decays in proton-proton collision data at a centre-of-mass energy 13 TeV collected by LHCb experiment, corresponding an integrated luminosity 2 fb$^{-1}$. ratio D^{*-}\tau^+\nu_{\tau...
We study the pole properties of $\Lambda(1405)$ in a model-independent manner by applying Uniformized Mittag-Leffler expansion proposed our previous paper. The resonant energy, width and residues are determined expanding observable as sum resonant-pole pairs under an appropriate parameterization which expresses to be single-valued, fitting it experimental data invariant-mass distribution $\pi^+...
We report magnetic and electrical measurements of Nb Josephson junctions with strongly ferromagnetic barriers of Co, Ni, and Ni80Fe20 (Py). All these materials show multiple oscillations of critical current with a barrier thickness implying repeated 0-pi phase transitions in the superconducting order parameter. We show, in particular, that the Co barrier devices can be accurately modeled using ...
A coherent study of $e^{+}e^{-}$ annihilation into two ($\pi^{+}\pi^{-}$,$K^{+}K^{-}$) and three ($\pi^{+}\pi^{-}\pi^{0},\pi^{+}\pi^{-}\eta$) pseudoscalar meson production is carried out within the framework resonance chiral theory in energy region $E\lesssim 2 \, \mathrm{GeV}$. The work {[}L. Y. Dai, J. Portol\'es, O. Shekhovtsova, Phys. Rev. D 88,056001 (2013){]} revisited with latest experim...
