Phosphorus triiodide (PI3) is an inorganic compound with the formula PI3. A red solid, it is too unstable to be stored; it is, nevertheless, commercially available. It is widely used in organic chemistry for converting alcohols to alkyl iodides. It is also a powerful reducing agent. Note that phosphorus also forms a lo...

The Gillis and Gilman approach considers bend and shear forces in the beam. The compliance equation is: C = 8 L 3 E ∗ w t 3 ( 1 + 3 c ( t L ) 2 − n + α s E ∗ 4 μ ( t L ) 2 ) {\displaystyle C={\frac {8L^{3}}{E^{*}wt^{3}}}\left(1+3c\left({\frac {t}{L}}\right)^{2-n}+{\frac {\alpha _{s}E^{*}}{4\mu }}\left({\frac {t}{L}}\ri...

In mathematics, the category of medial magmas, also known as the medial category, and denoted Med, is the category whose objects are medial magmas (that is, sets with a medial binary operation), and whose morphisms are magma homomorphisms (which are equivalent to homomorphisms in the sense of universal algebra). The ca...

Anthropologists no longer regard "race" as a useful concept in understanding human evolution and variation." The anthropologist C. Loring Brace (1996) concurred, stating that the book was an amalgamation of bad biology and inexcusable anthropology. It is not science but advocacy, and advocacy of 'racialism'". Similarly...

According to Richard R. Valencia, the response to the first edition of Rushton's book was "overwhelmingly negative", with only a small number of supporters, many being, like Rushton, Pioneer Fund grantees, such as psychologists Arthur Jensen, Michael Levin, Richard Lynn, and Linda Gottfredson.Valencia identified the ma...

Differential K theory is a debunked theory proposed by Rushton, which attempts to apply r/K selection theory to human races. According to Rushton, this theory explains race differences in fertility, IQ, criminality, and sexual anatomy and behavior. The theory also hypothesizes that a single factor, the "K factor", affe...

The book grew out of Rushton's 1989 paper, "Evolutionary Biology and Heritable Traits (With Reference to Oriental-White-Black Difference)". The 1st unabridged edition was published in 1995, the 2nd unabridged edition in 1997, and the 3rd unabridged edition in 2000. Rushton argues that Mongoloid, Caucasoid and Negroid p...

In structural geology section restoration or palinspastic restoration is a technique used to progressively undeform a geological section in an attempt to validate the interpretation used to build the section. It is also used to provide insights into the geometry of earlier stages of the geological development of an are...

In most section restorations there is an element of backstripping and decompaction. This is necessary to adjust the geometry of the section for the compactional effects of later sediment loading.

For elliptic partial differential equations, Harnack's inequality states that the supremum of a positive solution in some connected open region is bounded by some constant times the infimum, possibly with an added term containing a functional norm of the data: sup u ≤ C ( inf u + ‖ f ‖ ) {\displaystyle \sup u\leq C(\in...

In mathematics, Harnack's inequality is an inequality relating the values of a positive harmonic function at two points, introduced by A. Harnack (1887). Harnack's inequality is used to prove Harnack's theorem about the convergence of sequences of harmonic functions. J. Serrin (1955), and J. Moser (1961, 1964) generali...

Digital signal processing and other applications typically use fast convolution algorithms to reduce the cost of the convolution to O(N log N) complexity. The most common fast convolution algorithms use fast Fourier transform (FFT) algorithms via the circular convolution theorem. Specifically, the circular convolution ...
