String field theory (SFT) is a formalism in string theory in which the dynamics of relativistic strings is reformulated in the language of quantum field theory.This is accomplished at the level of perturbation theory by finding a collection of vertices for joining and splitting strings, as well as string propagators, that give a Feynman diagram-like expansion for string scattering amplitudes.
Confounding is defined in terms of the data generating model. Let X be some independent variable, and Y some dependent variable.To estimate the effect of X on Y, the statistician must suppress the effects of extraneous variables that influence both X and Y.
He expanded on the work Niels Nörlund had done on Euler polynomials as a solution to a particular difference equation. Cox used generalized Euler polynomials and the generalized Boole summation formula to expand on the Boole summation formula. He also studied a number of specialized polynomials as solutions for certain differential equations.
A great co-founder relationship is a beautiful thing. But if you cannot, it can be good to be a solo founder too! Just go hire a great team, and perhaps a co-founder will emerge from the ranks.
Henry Dunant, co-founder of the Red Cross. An organizational founder is a person who has undertaken some or all of the formational work needed to create a new organization, whether it is a business, a charitable organization, a governing body, a school, a group of entertainers, or any other type of organization.
Alexis Kerry Ohanian (Armenian: Ալեքսիս Քերի Օհանյան; born April 24, 1983) [1] is an American internet entrepreneur and investor. He is best known as the co-founder and former [2] executive chairman of the social media site Reddit along with Steve Huffman and Aaron Swartz.
He has made contributions to homogenization theory, theoretical models of turbulence, stochastic partial differential equations, electronic structure analysis, multiscale methods, computational fluid dynamics, and weak KAM theory. In the study of rare events, he and collaborators have developed the string method and transition path theory.
