Lectures on curved betagamma systems, pure spinors, and anomalies
"... The curved betagamma system is the chiral sector of a certain infinite radius limit of the nonlinear sigma model with complex target space. Naively it only depends on the complex structures on the worldsheet and the target space. It may suffer from the worldsheet and target space diffeomorphism an ..."

Curved BetaGamma Systems and Quantum Koszul Resolution
, 2006
"... We consider the partition function of betagamma systems in curved space of the type discussed by Nekrasov and Witten. We show how the Koszul resolution theorem can be applied to the computation of the partition functions and to characters of these systems and find a prescription to enforce the hypo ..."

Perturbed BetaGamma Systems and Complex Geometry, arXiv: 0708.0682
"... We consider the equations, arising as the conformal invariance conditions of the perturbed curved betagamma system. These equations have the physical meaning of Einstein equations with a Bfield and a dilaton on a hermitian manifold, where the Bfield 2form is imaginary and proportional to the can ..."

OPERATOR FORMALISM FOR BOSONIC BETAGAMMA FIELDS ON GENERAL ALGEBRAIC CURVES
, 1997
"... An operator formalism for bosonic β − γ system on arbitrary algebraic curves is introduced. The classical degrees of freedom are identified and their commutation relations are postulated. The explicit realization of the algebra formed by the fields is given in the Hilbert space equipped with a bilin ..."

LIQUID SCINTILLATION COUNTING RECENT APPLICATIONS AND DEVELOPMENT VOLUME I. PHYSICAL ASPECTS PULSE SHAPE LIQUID SCINTILLATION COUNTING FOR BETAS GAMMA OR BETAGAMMA COUNTING
"... A liquid scintillation counting system has been modified to expand the conventional beta counting capabilities to gamma counting as well as simultaneous betagamma counting. The increased response of the counter is made possible by utilizing a gamma radiation detector as a sample vial holder and pu ..."

Behavioral/Systems/Cognitive Synchrony Makes Neurons Fire in Sequence, and Stimulus Properties DetermineWho Is Ahead
"... The synchronized activity of cortical neurons often features spike delays of severalmilliseconds. Usually, these delays are considered too small to play a role in cortical computations.Here, weuse simultaneous recordings of spiking activity fromup to 12neurons to show that, in the cat visual cortex, ..."

This suggests that, in the visual system, shortlived spatiotemporal patterns of spiking defined by consistent delays in synchronized activity occur with sufficient reliability
