Some Problems Relating to the Dorsal Spinal Nerve Roots *

Discussion in the past has centered around three particular aspects of the dorsal spinal roots. I refer specifically to the possible "pain pathway" along unmyelinated nerve fibres, the location of the cell station of the visceral afferent fibres, and the explanations offered for the vasodilator response obtained by stimulation of the distal ends of the dorsal spinal roots. Opinion is now settli...

Some problems related to hamiltonian line graphs

Part of this paper summarizes some of the recent developments in the study of hamiltonian line graphs and the related hamiltonian claw-free graphs. The last section of this paper solves some problems on the hamiltonian like indices from a paper by Clark and Wormald in 1983. 1. Definitions and Terminology Graphs considered here are finite and loopless. Unless otherwise noted, we follow [2] for n...

Some New Approaches to Solving Constrained Transfer Line Matching Problems

A common type of matching problem involves finding the strengths for four (4) quadrupoles in a transfer line, that will transport a particular beam at the entrance, to produce a beam at the exit of the line with a specified set of horizontal and vertical Twiss parameters. A number of optics programs may be used to find a solution to this type of problem, but the quadrupole strengths obtained ar...
