Fourier's central idea is what his translator and acolyte Albert Brisbane calls "Attractive Industry," or the principle that individuals ought to perform the labor and seek the romantic ties that are most emotionally attractive to them, regardless of prevailing social institutions (24).
The Further Cardiovascular outcomes Research with PCSK9 inhibition in subject with elevated risk (Fourier) trial was the pivotal efficacy and safety study for the proprotein convertase subtilisin- kexin type 9 (PCSK9) inhibitor evolocumb (Repatha) and enrolled patients with atherosclerotic cardiovascular disease and LDL cholesterol levels of at least 70 mg/d.
Kaniuth and Lau survey roughly 50 years of research into the role that Fourier and Fourier-Stieltjes algebras has played not only in helping clarify the natural of locally compact groups, but also in building bridges between abstract harmonic analysis, Banach algebras, and operator algebras.
The GS algorithm was originally proposed in connection with the problem of reconstructing phase given only two-intensity measurements in the spatial domain and Fourier domain, i.e., given two intensity measurements (one is recorded in the spatial domain and the other is estimated in the Fourier domain) measurements.
Relationship between Quaternion Fourier Transform (QFT) and Quaternion Linear Canonical Transform (QLCT)
ANAHEIM, CALIF.--Patients with symptomatic peripheral artery disease or a high-risk history of MI got the biggest bang for the buck from aggressive LDL cholesterol lowering with evolocumab, according to two new prespecified subgroup analyses from the landmark FOURIER trial presented at the American Heart Association scientific sessions.
The international study, dubbed FOURIER, enrolled more than 27,500 patients, 81 percent of whom had a history of heart attack, 19 percent had suffered a stroke, and 13 percent had symptomatic peripheral arterial disease.
WASHINGTON --The PCSK9 inhibitor evolocumab reduced the incidence of the composite endpoint of cardiovascular death, MI, or stroke by an additional 20% in patients with established cardiovascular disease who were already on background maximum-tolerated statin therapy in the landmark FOURIER trial, Marc S.
Several different approaches such as short-time Fourier transform, Wigner-Ville distribution, discrete wavelet transform, discrete cosine transform, and chirplet transform, and Fractional Fourier transform have been proposed to cope with the overlapping problem [1, 8].

In this paper, we first derive the HL consistency conditions in the 2D Fourier domain from their original formulation.
Then, we extract gear fault features around the resonance frequency via sideband analysis in Fourier spectrum, and amplitude and frequency demodulation analysis.
The classical Poisson summation formula, which demonstrates that the sum of infinite samples in the time domain of a signal f(t) is equivalent to the sum of infinite samples of F(x) in the Fourier domain, is of importance in theories and applications of signal processing [1].
It is well-known that smooth periodic functions can be approximated well by Fourier series [1,2].
