TAVI: Simplification Is the Ultimate Sophistication

Simplicity: the ultimate sophistication.

Efficient movement underpins all great sporting performances. When performed by an expert, complex movements can appear effortless, almost simple; as Leonardo Da Vinci stated, “simplicity is the ultimate sophistication”. Dynamic control of movement is also central to safe sporting function and is dependent on the sophisticated integration of a range of factors including environment, nature of t...

A proof of hyperbolic van der Waerden conjecture : the right generalization is the ultimate simplification

Consider a homogeneous polynomial p(z1, ..., zn) of degree n in n complex variables . Assume that this polynomial satisfies the property : |p(z1, ..., zn)| ≥ ∏ 1≤i≤n Re(zi) on the domain {(z1, ..., zn) : Re(zi) ≥ 0, 1 ≤ i ≤ n} . We prove that | ∂ n ∂z1...∂zn p| ≥ n! n . Our proof is relatively short and self-contained (i.e. we only use basic properties of hyperbolic polynomials ). As the van de...

Water oxidation by manganese oxides, a new step towards a complete picture: simplicity is the ultimate sophistication.

We, for the first time, report that many Mn oxides (Mn3O4, α-Mn2O3, β-MnO2, CaMnO3, Ca2Mn3O8, CaMn3O6 and CaMn4O8) in the presence of cerium(IV) ammonium nitrate, in the water oxidation, convert to layered Mn oxide. This layered Mn oxide is an efficient water oxidizing catalyst.

The sophistication of exports: Is China special?

Article history: Received 7 March 2008 Received in revised form 19 April 2010 Accepted 19 April 2010 Recent studies have found that China is “special” in exporting highly sophisticated goods not comparable with its income level. In this paper we identify two measurement biases that account for this “China is special” observation. First, product quality has not been fully considered in the measu...
