分别给出了非奇异M-矩阵的逆矩阵和非奇异M-矩阵的Hadamard积与非奇异M-矩阵Fan积的最小特征值下界新的估计式;同时给出了非负矩阵Hadamard积的谱半径上界新的估计式;这些估计式都只依赖于矩阵的元素,易于计算.算例表明,这些估计式在一定条件下改进了现有结果.
Velocity measurements for a solar active region fan loop from Hinode/EIS observations
Velocity measurements solar active region observations
2011/10/8
The velocity pattern of a fan loop structure within a solar active region over the temperature range 0.15-1.5 MK is derived using data from the EUV Imaging Spectrometer (EIS) on board the Hinode satel...
A new topological construction of infinite families of toric manifolds implying fan reduction
topological construction toric manifolds
2010/11/8
An infinite family of toric manifolds is constructed from a given one $M^{2n}$, using only the original characteristic function (or fan) data. This is done in a way which simplifies significantly the...
Sea fan corals provide a stable isotope baseline for assessing sewage pollution in the Mexican Caribbean
Sea fan corals provide a stable isotope baseline sewage pollution the Mexican Caribbean
2014/4/16
We compared stable nitrogen isotope (d15N) values from the common Caribbean sea fanGorgonia ventalina,collected from a developed and undeveloped coastline, to test the hypothesis that sewage-derived n...
Nitrogen source preference ofAspergillus sydowii, an infective agent associated with aspergillosis of sea fan corals
Nitrogen source preference Aspergillus sydowii an infective agent associated aspergillosis sea fan corals
2014/4/16
We attempt to identify the mechanism by which nitrogen enrichment increases the prevalence of aspergillosis, a disease caused by the terrestrial fungus Aspergillus sydowii, which infects sea fan coral...
