Email: [email protected] Cervical spondylotic myelopathy (CSM) is the most common cause of spinal dysfunction in the elderly (77). It is also the most common cause of nontraumatic spastic paraparesis and quadriparesis. In one series, 23.6% of all patients presenting with nontraum...

Small, involuntary and unperceivable eye movements occur during visual fixation and are classified into three types: tremor, drift and microsaccades (Barlow, 1952; Ratliff and Riggs, 1950; Steinman, Haddad, Skavenski, and Wyman, 1973; Martinez-Conde et al., 2004). Although there is some debate as to their function (see Rolfs, 2009 and Martinez-Conde et al., 2009 for reviews), it appears that th...

It is a long standing open problem to find an explicit description of the stable set polytope of clawfree graphs. Yet more than 20 years after the discovery of a polynomial algorithm for the maximum stable set problem for claw-free graphs, there is even no conjecture at hand today. Such a conjecture exists for the class of quasi-line graphs. This class of graphs is a proper superclass of line g...
