The phrase "exist by using" is correct and usable in written English.
It can be used to refer to something that exists because of its use. For example: Many of the traditional tools for farming still exist by using modern technology.
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.
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).
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.
For large samples, we show that a satisfactory, likelihood-based general solution exists by using appropriate forms of the relative Kullback Leibler information, and that the proposed measures are computationally inexpensive given the maximized likelihoods with the observed data.
Since the region of scintillation coincides with the plasma bubble, we can investigate the location where plasma bubble exists by using GPS-scintillation monitoring.
In this study, we tested a bioinformatics method of SNP discovery in a species where presently no SNP-chip genotyping platform exists by using the high-throughput platform of gene expression short oligonucleotide arrays to mine thousands of transcripts simultaneously.
Infinite families of Ramanujan graphs were first shown to exist by Margulis and Lubotzky, Phillips and Sarnak using Deligne's proof of the Ramanujan conjecture.
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.
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.
TSE, a repression mechanism shown to exist by the use of P-transgenes, is likely a major component of P element repression elicited by natural telomeric P elements.
