Shuffle randomization
In a randomized clinical trial, study participants are assigned to various treatment arms through randomization. This random allocation of participants to treatment arms decreases bias and controls for numerous confounders (1). A common type of randomization is simple randomization, where each participant is randomly assigned to a treatment arm with a known (usually equal) probability, regardle...
متن کاملRandomization Time for the Overhand Shuffle
1. THE OVERHAND SHUFFLE (~o The two most common methods of shuffling a deck of playing cards are the riffle shuffle and the overhand shuffle. The riffle shuffle is performed by splitting the deck into two halves and interlacing them. Aldous and Diaconis have shown in Ref. I that approximately 2 log N riffle shuffles suffices to randomize a deck (the meaning of this will be made more precise bel...
متن کاملShuffle Bialgebras
The goal of our work is to study the spaces of primitive elements of the Hopf algebras associated to the permutahedra and the associahedra. We introduce the notion of shuffle bialgebras, and compute the subpaces of primitive elements associated to these algebras. These spaces of primitive elements have natural structure of some type of algebras which we describe in terms of generators and relat...

The goal of our work is to study the spaces of primitive elements of the Hopf algebras associated to the permutaedra and the associaedra. We introduce the notion of shuffle and preshuffle bialgebras, and compute the subpaces of primitive elements associated to these algebras. These spaces of primitive elements are free objects for some types of algebras which we describe in terms of generators ...
متن کاملShuffle Memory System
This paper proposes a new memory system called shuffle memory. The shuffle memory is a generalization of transposition memory that has been widely used in 2-D Discrete Cosine Transform and Discrete Fourier Transform. The shuffle memory is the first memory system that receives M N inputs in row major while providing M N outputs in column major order using only M N memory space. Shuffle memory ca...
