How to find all roots of complex polynomials by Newton’s method
complex polynomials Newton’s method
2015/8/26
We investigate Newton’s method to find roots of polynomials of fixed degree d, appropriately normalized: we construct a finite set of points such that, for every root of every such polynomial, at leas...
Marine Geological and Geophysical Roots of the Ocean Observatories Initiative
Marine Geological Geophysical Roots Ocean Observatories Initiative
2015/7/31
The ocean sciences are based on a rich exploratory heritage that dates back over a century, and expeditionary oceanography on dedicated research vessels will remain a vital component of current ocean ...
Below the Salt Marsh Surface: Visualization of Plant Roots by Computer-Aided Tomography
Computer-Aided Tomography Salt Marsh Surface
2015/7/16
As sea level rises, salt marshes become subtidal mudflats unless soil surface accretion occurs at rates fast enough to keep the marsh from being submerged (Brinson et al., 1995). The individual proces...
ON SQUARE ROOTS OF THE UNIFORM DISTRIBUTION ON COMPACT GROUPS
Separate topology group probability quaternion group organization properties
2015/7/14
Let G be a compact separable topological group. When does there exist a
probability P such that P P = U ,where U is Haarmeasure and P + U? We show
that such square roots exist if and only if G is ...
Ethylene negatively regulates aluminium-induced malate efflx from wheat roots and tobacco cells transformed with TaALMT1
Ethylene aluminium tolerance malate efflx ALMT1 wheat (Triticum aestivum L.)
2015/2/5
An important mechanism for Al3+ tolerance in wheat is exudation of malate anions from the root apex through activation of malate-permeable TaALMT1 channels. Here, the effect of ethylene on Al3+-activa...
Ethylene-responsive miRNAs in roots of Medicago truncatula identified by high-throughput sequencing at whole genome level
Ethylene microRNA Medicago truncatula High-throughput sequencing
2015/2/5
Ethylene is one ofthe classical plant hormones with a diverse function in plant growth and development. Root elongation is sensitive to ethylene such that treatments with ethylene and the ethylene pre...

A new study from a research team led by biochemist Chang-Jun Liu at the U.S. Department of Energy's Brookhaven National Laboratory identifies the protein essential for relocating cytokinins from roots...
Symbiotic fungi inhabiting plant roots have major impact on atmospheric carbon, scientists say（图）
Symbiotic fungi
2014/3/17
AUSTIN, Texas — Microscopic fungi that live in plants' roots play a major role in the storage and release of carbon from the soil into the atmosphere, according to a University of Texas at Austin rese...
Seasonal variation of isoprene basal emission in mature Quercus crispula trees under experimental warming of roots and branches
isoprene biogenic volatile emission Quercus crispula experimental warming
2017/4/11
Isoprene is a reactive volatile organic compound (VOC), the annual global biogenic emissions of which are the largest
of the non-methane VOC. Since isoprene emissions are partly temperature-driven, u...
A New Algorithm to Compute the Square Roots of r -circulant Matrices
r-circulant matrices primary square root reduced form Schur decomposition
2012/9/24
A simplified form of r-circulant matrices is investigated , and a new algorithm to compute the square roots of r -circulant matrices is obtained using the properties of r -circulant matrices. In st...
q-damped Oscillator and degenerate roots of constant coefficients q-difference ODE
q-damped Oscillator degenerate roots coefficients q-difference ODE
2011/9/5
Abstract: The classical model of q-damped oscillator is introduced and solved in terms of Jackson q-exponential function for three different cases, under-damped, over-damped and the critical one. It i...
Higher order Glaeser inequalities and optimal regularity of roots of real functions
Glaeser inequality absolutely continuous functions roots of real functions Holder continuous functions
2011/9/6
Abstract: We prove a higher order generalization of Glaeser inequality, according to which one can estimate the first derivative of a function in terms of the function itself, and the Holder constant ...
