Quantal phase factors accompanying adiabatic changes
A quantal system in an eigenstate, slowly transported round a circuit C by varying parameters R in its Hamiltonian Ĥ(R), will acquire a geometrical phase factor exp{iγ(C)} in ad...

The human brain is intrinsically organized into dynamic, anticorrelated functional networks
During performance of attention-demanding cognitive tasks, certain regions of the brain routinely increase activity, whereas others routinely decrease activity. In this study, w...

A Rating Scale for Mania: Reliability, Validity and Sensitivity
Summary An eleven item clinician-administered Mania Rating Scale (MRS) is introduced, and its reliability, validity and sensitivity are examined. There was a high correlation be...
A Theory of the Term Structure of Interest Rates
This paper uses an intertemporal general equilibrium asset pricing model to study the term structure of interest rates. In this model, anticipations, risk aversion, investment a...
Principal component analysis: a review and recent developments
Large datasets are increasingly common and are often difficult to interpret. Principal component analysis (PCA) is a technique for reducing the dimensionality of such datasets, ...
Hybridization of denatured RNA and small DNA fragments transferred to nitrocellulose.
A simple and rapid method for transferring RNA from agarose gels to nitrocellulose paper for blot hybridization has been developed. Poly(A)+ and ribosomal RNAs transfer efficien...
