New Acceleration of Nearly Optimal Univariate Polynomial Root-findERS

open access: yes, 2020
Univariate polynomial root-finding has been studied for four millennia and is still the subject of intensive research. Hundreds of efficient algorithms for this task have been proposed. Two of them are nearly optimal.

Evaluation of pan coefficient equations for estimating reference crop evapotranspiration in the arid region

open access: yesArchives of Agronomy and Soil Science, 2013
Reference evapotranspiration (ET0) can be estimated on basis of pan evaporation data (Epan), whose measurements have the advantage of low cost, simplicity of the measuring equipment, simple data interpretation and application as well as suitability for locations with limited availability of meteorological data.

Suppression of cell cycle progression by Jun dimerization protein (JDP2) involves down-regulation of cyclin A2 [PDF]

open access: yes, 2009
We report here a novel role for Jun dimerization protein-2 (JDP2) as a regulator of the progression of normal cells through the cell cycle. To determine the role of JDP2 in vivo, we generated Jdp2 knock-out (Jdp2KO) mice by targeting exon 1 to disrupt ...

Performance of Some Evapotranspiration Equations in an Arid Region

open access: yesWalailak Journal of Science and Technology, 2014
Estimation of evapotranspiration is necessary for planning, design and irrigation design and water resources management. In order to determine the best method to estimate evapotranspiration using data of Qom synoptic meteorological stations during the ...

NMR STUDIES ON SELF DIFFUSION COEFFICIENTS OF LITHIUM IONS IN PAN-BASED GEL POLYMER ELECTROLYTES

open access: yesActa Physica Sinica, 1999
The self diffusion coefficients D of lithium ions in PAN-EC/PC-LiClO4 gel polymer electrolytes with different compositions and at different temperatures have been directly measured by field gradient NMR spin echo technique. The results indicated that self diffusion coefficients D of lithium ions were dependent on the mass ratio x% of lithium salt, and ...

The Institutional Foundation of Foreign-Invested Enterprises (FIEs) in China [PDF]

open access: yes, 1999
Foreign-invested enterprises (FIEs) are now an important component of the Chinese economy. Since 1992, the growth of FIEs has been exponential. However our understanding of the institutional factors driving the FIE growth remains limited. This paper uses
