The reflectormirror is the most important component of an astronomical optical telescope. This chapter provides discussions on the requirements for astronomical optical mirrors; the ways to reduce mirror weight, mirror cost, and mirror materials; the methods of mirror figuring, polishing, and surface coating; the design of mirror support mechanism; the concept of mirror seeing; and the stray li...

The human mirror system has been the subject of much research over the past two decades, but little is known about the timecourse of mirror responses. In addition, it is unclear whether mirror and counter-mirror effects follow the same timecourse. We used single-pulse transcranial magnetic stimulation to investigate the timecourse of mirror and counter-mirror responses in the human brain. Exper...

In this paper, we propose three classes of multi-valued signature sequences for direct sequence code division multiple access (DS/CDMA) systems. The first class derived from the two-band perfect reconstruction quadrature mirror filter (PR-QMF) bank has perfect correlation properties when the number of users is two in the DS/CDMA system. The first two classes have perfect correlation properties ...

We are grateful to José Bermúdez and to Andrea Cristiano Pierno, Caterina Ansuini and Umberto Castiello for reading and criticizing our book. They offer us an opportunity to clarify some of our views. Bermúdez discusses aspects of our version of the two-visual systems model of human vision bearing on the separation between the content of visuomotor representations and the content of visual perc...
