Introduction: Early differentiation of biliary atresia from neonatal hepatitis is of utmost importance, since on time surgery of biliary atresia significantly improves the outcome. Hepatobiliary scintigraphy is an integral part of diagnosis work-up of these patients; however its specificity for diagnosis of biliary atresia is suboptimal. In this study we evaluated the value of ursodeoxycholic a...
Technetium is an element that is artificially produced and all its isotopes are radioactive. Several investigations have been performed on the subject of the production of Tc radioisotopes using cyclotrons. Among these radioisotopes, 99mTc with a half-life of 6.02 h and gamma-ray spectrum with an energy peak at 140.5 keV has a vast application in nuclear medicine. More than 85% of administered ...

Abstract We present the details and first results of a new strategy for determination $$\alpha _s(m_Z)$$ α s ( m Z ) (ALPHA Collaboration et al. in Phys. Lett. B 807:135571, 2020)...
We produce carrier-envelope-phase-stable 15.7-fs (2-cycle) 740μJ pulses at the 2.1-μm carrier wavelength, from a three-stage optical parametric chirped-pulse amplifier system, pumped by an optically synchronized 49-ps 11-mJ Nd:YLF laser. A novel seed pulse spectral shaping method is used to ascertain the true amplified seed energy and the parametric superfluorescence levels. ©2008 Optical Socie...
We discuss a novel method for generating octave-spanning supercontinua and few-cycle pulses in the important mid-IR wavelength range. The technique relies on strongly phase-mismatched cascaded second-harmonic generation (SHG) in mid-IR nonlinear frequency conversion crystals. Importantly we here investigate the so-called noncritical SHG case, where no phase matching can be achieved but as a com...
