Results: A total of 247 plastic surgeons were included. 78.6% cited previous work at least once (mean 34.3 +/87.5 self-citations). These self-citations accounted for 4.8% of all citations. Including self-citations in bibliometric analyses increased h-indices from 9.5 +/6.9 to 10.2 +/7.6. A minority of researchers (20.1%) increased their h-index via self-citation by at least one integer value (r...

We report a combined thermodynamic and structural characterization of a DNA tetraplex. Using spectroscopic and calorimetric techniques, we demonstrate that d(TG3T) and d(TG3T2G3T), in the presence of K+, form stable tetramolecular complexes. From differential scanning calorimetry measurements, we obtain the following thermodynamic profiles for formation of each tetraplex at 25 degrees C: delta ...

We derive exact expressions for the local entanglement entropy epsilon in the ground state of the one-dimensional Hubbard model at a quantum phase transition driven by a change in magnetic field h or chemical potential mu. The leading divergences of delta epsilon/delta h and delta epsilon/delta mu are shown to be directly related to those of the zero-temperature spin and charge susceptibilities...

The standard enthalpy of formation and the enthalpy of sublimation of crystalline 2-hydroxyphenazine-di-N-oxide, at T = 298.15 K, were determined from isoperibol static bomb combustion calorimetry and from Knudsen effusion experiments, as -76.7 +/- 4.2 kJ.mol(-1) and 197 +/- 5 kJ.mol(-1), respectively. The sum of these two quantities gives the standard enthalpy of formation in the gas-phase for...

abstract the aim of this research was to investigate the enthalpy variations of iranian flat breads during storage in room temperature and determining relationship between enthalpy and amount of staling development. for this purpose, the major iranian breads including barbari, taftoon, lavash and sangak beside baguette, were prepared using standard ingredients, specific recipe, and under contro...
