Analyzing coefficients of psychophysical power functions [PDF]

open access: yesPerception & 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 ...

Power Coefficient for Large Wind Turbines Considering Wind Gradient Along Height

open access: yesEnergies
The Betz constant is the well-known aerodynamic limit of the maximum power which can be extracted from wind using wind turbine technologies, under the assumption that the wind speed is uniform across a blade disk. However, this condition may not hold for

Psychosocial Functioning After Pediatric Bone Sarcoma: Generic and Survivor‐Specific Outcomes in Adolescent and Young Adult Patients

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Pediatric bone sarcoma patients and survivors may experience psychosocial challenges related to childhood cancer after their intensive, body‐altering treatment. This cross‐sectional study aimed to evaluate generic and survivor‐specific psychosocial outcomes in a national cohort of pediatric bone sarcoma patients and survivors, and ...

Prime power divisors of binomial coefficients

open access: yesDiscrete 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 ...

The Relationship Between Physical Activity and Left Ventricular Remodeling in Childhood Cancer Survivors Treated With Anthracyclines: A Cross‐Sectional Study

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction Anthracycline‐related cardiac remodeling precedes heart failure in childhood cancer survivors. The objectives of this study were to determine the relationships between patient‐specific factors, moderate‐to‐vigorous physical activity (MVPA), and cardiac remodeling.

On the Zeros of Power Series with Logarithmic Coefficients [PDF]

open access: yesCanadian 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.

An Apparatus for Determining Coefficients in Power Series [PDF]

open access: yesMathematical Notes, 1932
The diagrammatic figure illustrates the principle involved. The vertical full lines represent ordinates of a curve of which theabscissae are Oa1, Oa2, etc. Let now all these vertical lines be rotated round the points O, a1, a2, etc., while retaining their original lengths, through the same angle θ. The curve passing through the new positions of the end
