The Coefficients of a Fibonacci Power Series
The Fibonacci Quarterly, 2004 We give a short proof of the result that all the coefficients of the series (1-x)(1-x^2)(1-x^3)(1-x^5)(1-x^8)(1-x^13)(1-x^21)... are equal to -1, 0, or 1, and most of them are equal to 0.

Analyzing coefficients of psychophysical power functions [PDF]
Perception & Psychophysics, 1993 Some mathematical properties of coefficients of power functions were analyzed. The size of correlations between intercepts (the logarithm of the coefficient) and exponents depends on the choice of unit of measurement of the physical stimuli. When the mean of logarithms of a set of responses is uncorrelated with the exponent, the absolute size of the ...

Performance Analysis of Side-by-Side Savonius Hydrokinetic Turbines Under Different Flow Velocities [PDF]
E3S Web of ConferencesThe increasing demand for renewable energy has spurred the development of environmentally friendly technologies. Hydrokinetic turbines, which generate electricity from flowing water without dams or reservoirs, are a promising option.

On-line estimation of the parameters of the windmill power coefficient
Systems & Control Letters, 2022 Wind turbines are often controlled to harvest the maximum power from the wind, which corresponds to the operation at the top of the bell-shaped power coefficient graph. Such a mode of operation may be achieved implementing an extremum seeking data-based strategy, which is an invasive technique that requires the injection of harmonic disturbances ...

Prime power divisors of binomial coefficients
Discrete Mathematics, 1999 This excellent paper provides \textit{asymptotic} bounds for the number of primes \(p\) such that \(p^r\|\binom{n}{m}\), when \(n\) goes to infinity and \(m\) is larger than some power of \(n\). The uniformity in \(r\) is furthermore carried out. The method is deceptively simple looking and relies on a lemma (Lemma~3) of great generality that gives a ...

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Maintenance hemodialysis (MHD) patients frequently suffer from frailty, characterized by reduced physical function and poor prognosis. Myokines, such as myonectin, secreted by muscle, are emerging regulators of systemic health. This study investigated the relationship between serum myonectin, adipokines (adiponectin, omentin), and ...

On the Zeros of Power Series with Logarithmic Coefficients [PDF]
Canadian Mathematical Bulletin, 1979 Equivalence problems in Riesz-summability lead to the problem of finding the zeros of special power series in the unit circle, i.e.

Therapeutic Apheresis and Dialysis, EarlyView.ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...
