Eye movements in vertebrates are controlled by six extraocular muscles innervated by three of the cranial nerves – the oculomotor, trochlear and abducens. Incorrect development of this wiring network can lead to eye movement disorders, such as the congenital condition Duane retraction syndrome (DRS), which results in squint (strabismus). In DRS patients, the abducens nerve is often absent, and ...

With the aid of modern electromyography, numerous authors (Pabst and Esslen, I960; Sato, ig60; Orlowski and W6jtowicz, I962; Burger, I963; Blodi, van Allen, and Yarbrough, I964; Huber and Esslen, I969) have recently come to the (surprisingly) unanimous conclusion that a paradoxical innervation of the external rectus muscle of the affected eye represents the pathogenetic principle of all the ret...

Abstract Bremsstrahlung spectra produced by 5 keV electrons incident on Al2O3 and MgO targets at air pressures of 30, 50, 100 Pa have been compared with results using pyPENELOPE, a program designed to simulate electron microscopy. The comparisons showed that the experimental were in good agreement simulated except near Duane–Hunt limit, where bremsstrahlung amplitudes consistently greater than ...

We prove Khintchine type inequalities for words of a fixed length in a reduced free product of C∗-algebras (or von Neumann algebras). These inequalities imply that the natural projection from a reduced free product onto the subspace generated by the words of a fixed length d is completely bounded with norm depending linearly on d. We then apply these results to various approximation properties ...
