The next result gives the soluti...

In the same article, Kwapień proved that the validity of a Banach-valued Parseval's theorem for the Fourier transform characterizes Banach spaces isomorphic to Hilbert spaces. Lindenstrauss and Tzafriri proved that a Banach space in which every closed linear subspace is complemented (that is, is the range of a bounded ...

Lambda (written λ, in lowercase) is a non-SI unit of volume equal to 10−9 m3, 1 cubic millimetre (mm3) or 1 microlitre (μL). Introduced by the BIPM in 1880, the lambda has been used in chemistry and in law for measuring volume, but its use is not recommended.This use of λ parallels the pre-SI use of μ on its own for a ...

The theorems can be simply derived by applying the differential operator ∂μ to both sides of the Schrödinger equation H | n ⟩ = E n | n ⟩ , {\displaystyle H|n\rangle =E_{n}|n\rangle ,} which reads Then overlap with the state ⟨ m | {\displaystyle \langle m|} from left and make use of the Schrödinger equation ⟨ m | H = ⟨...

The above power series expansion can be readily evaluated if there is a systematic approach to calculate the derivates to any order. Using the chain rule, the derivatives can be broken down to the single derivative on either the energy or the state. The Hellmann–Feynman theorems are used to calculate these single deriv...

From the differential geometric point of view, a parameterized Hamiltonian is considered as a function defined on the parameter manifold that maps each particular set of parameters ( x 1 , x 2 , ⋯ ) {\displaystyle (x^{1},x^{2},\cdots )} to an Hermitian operator H(x μ) that acts on the Hilbert space. The parameters here...

The tail addition step in this synthesis (Scheme 6) was identical to that in the Nicolaou tail addition and was based on Oijma chemistry. The A ring was functionalized with a hydroxyl group through pyridinium chlorochromate oxidation of α-acylketone 49 to form ketone 50. Subsequent reduction using sodium borohydride pr...

The second part of the B ring synthesis (Scheme 5) was concerned with correct chemistry for the newly formed ethylene bridge connecting the A and C rings. After Scheme 4, this bridge contained an exocyclic methylene group, but in the ultimate taxol molecule this bridge is an α-acylketone. The required conversion was ac...

This compound is commercially available as a single enantiomer and the single chiral group present in this molecule is able to drive the entire sequence of organic reactions to a single optically active Taxol endproduct. The final step, the tail addition is identical to that of Nicolaou and is based on Ojima chemistry....

The Danishefsky Taxol total synthesis in organic chemistry is an important third Taxol synthesis published by the group of Samuel Danishefsky in 1996 two years after the first two efforts described in the Holton Taxol total synthesis and the Nicolaou Taxol total synthesis. Combined they provide a good insight in the ap...

Treatment of this epoxide with aluminium isopropoxide gave allylic alcohol 8. Two more hydroxyl groups were added by oxidation of the newly formed double bond with a catalytic amount of osmium tetroxide in the presence of N-methylmorpholine N-oxide. This reaction lacked stereospecificity and the yield of triol 9 with t...

Let Ω be an open subset of C {\displaystyle \mathbb {C} } and E a relatively closed subset of Ω. By Ω* is denoted the Alexandroff compactification of Ω. Arakelyan's theorem states that for every f continuous in E and holomorphic in the interior of E and for every ε > 0 there exists g holomorphic in Ω such that |g − f| ...

In mathematics, Arakelyan's theorem is a generalization of Mergelyan's theorem from compact subsets of an open subset of the complex plane to relatively closed subsets of an open subset.

The collection of MPD, however, is continuous and can cover the majority of the population. Also, since passive mobile positioning data is collected continuously by mobile network operators, it offers the possibility of generating statistics on a very granular level. Furthermore, it allows producing near real-time stat...

The digital footprint left by mobile device users is sensitive, but also highly valuable, as it provides new possibilities of measuring and monitoring the spatio-temporal activities of the population. This makes MPD a great data source for gathering statistics, as it can fill in the gaps where other data sources are la...
