Type B Topological Matter , Kodaira - Spencer Theory , and Mirror Symmetry

Perturbing usual type B topological matter with vector (0, 1)-forms we find a topological theory which contains explicitly Kodaira-Spencer deformation theory. It is shown that, in genus zero, three-point correlation functions give the Yukawa couplings for a generic point in the moduli space of complex structures. This generalization of type B topological matter seems to be the correct framework...

The fall of tsarism in Russia in 1917 was the culmination of many factors. It is perhaps widely noted that Nicholas II was not suited to his role as Tsar, mainly due to his character and personality. Resentment of his wife and her involvement with the mystical Rasputin was also widespread and helped contribute to the collapse of the monarchy. Also the state of the country during World War One l...

Grafts of autologous keratinocytes genetically altered to secrete a new gene product are a potential vehicle for gene therapy. T o consider the feasibility of such an approach, w e have examined the ability of keratinocytes to secrete and deliver apolipoprotein E (apoE) to the circulation of mice bearing grafts of h u m a n keratinocytes. The grafted keratinocytes secreted two forms of apoE, an...

Auditory attention — focusing the searchlight on sound Jonathan B Fritz

Some fifty years after the first physiological studies of auditory attention, the field is now ripening, with exciting recent insights into the psychophysics, psychology, and neural basis of auditory attention. Current research seeks to unravel the complex interactions of pre-attentive and attentive processing of the acoustic scene, the role of auditory attention in mediating receptive-field pl...
