Next, we propose a method for estimating the spheres on which source signals exist by using ICA solution and the near-field model.
In the late 1990s, though, with so many IPOs rising so fast on the first day of trading, many have alleged that bankers broke one the few rules that do exist by using IPO shares to attract kickbacks or, as in Chacon's lawsuit, as bribes.
Instead, we arrived at the 26 studies by individually verifying the 38 studies that we knew to exist by using author name and title words.
A recent study also showed that an intermediate state of stem cell induction can exist, by using just a few of the transcription factors (Lin et al., 2011).
For any given positive constant M ≤ 1, w (x) = Mψ (x) is a supersolution of problem (1.1) provided that u0 (x) ≤ ψ (x) < 1 and a < ε 0 ( Ω K ¯ ) - 1, so the solution of (1.1) exists globally by using the comparison principle.
He was the first to doubt the significance of nonconstructive existence proofs (proofs that show something must exist, often by using a proof through contradiction, but that give no method of producing them), and for many years he carried on a polemic against the analytic school of the German mathematician Karl Weierstrass concerning these proofs and other points of classical analysis.
Today, aside from clinical aspects, an additional distinction exists by the use of gene profiling, identifying two different subtypes, stratified by different survival times (Alizadeh et al, 2000).
These observations encouraged us to investigate further whether such tetramers might exist in solution by using the more sensitive methods of sedimentation velocity and small-angle X-ray scattering (SAXS).
Notwithstanding the above potential limitations, this study suggests that disease signatures derived from large scale analysis of blood samples from psychiatric patients may exist and could be detected by using large and well characterized sample sets.
