Generalized “bra-ket” formalism
The Dirac’s bra-ket formalism is generalized to finite-dimensional vector spaces with indefinite metric in a simple mathematical context similar to thatof the theory of general tensors where, in addition, scalar products are introduced with the help of a metric operator. The specific calculation rules are given in a suitable intuitive notation. It is shown that the proposed bra-ket calculus is ...
متن کاملDIRAC’s BRA AND KET NOTATION
1 From inner products to bra-kets Dirac invented a useful alternative notation for inner products that leads to the concepts of bras and kets. The notation is sometimes more efficient than the conventional mathematical notation we have been using. It is also widely although not universally used. It all begins by writing the inner product differently. The rule is to turn inner products into bra-...
متن کاملPush up bras and bra sizing
Push up bras and bra sizing [1] Hi, I recently purchased some push up bras. However, when I wear one, it starts to feel kind of weird. I'm not sure how to explain the feeling but it almost feels tight on my bust. I can really feel the wire. Are push-up bras supposed to feel that way? Am I wearing the wrong size? I don't think I'm wearing the wrong size; if I wore a regular bra in that size, it'...
متن کاملSpeaker Modeling from Selected Nei Recognitio
This paper addresses the estimation of a speaker GMM through the selection and merging of a set of neighbors models for that speaker. The selection of the neighbors models is based on the likelihood score for the training data on a set of potential neighbor GMM. Once the neighbors models are selected, they are merged to give a model of the speaker, which can also be used as an a priori model fo...
متن کاملEscherichia coli endonuclease VIII: cloning, sequencing, and overexpression of the nei structural gene and characterization of nei and nei nth mutants.
Escherichia coli possesses two DNA glycosylase/apurinic lyase activities with overlapping substrate specificities, endonuclease III and endonuclease VIII, that recognize and remove oxidized pyrimidines from DNA. Endonuclease III is encoded by the nth gene. Endonuclease VIII has now been purified to apparent homogeneity, and the gene, nei, has been cloned by using reverse genetics. The gene nei ...
