    "abstract": "A new Rayleigh-type instability is proposed to explain the `sausage-string\u0027\npattern of alternating constrictions and dilatations formed in blood vessels\nunder influence of a vasoconstricting agent. Our theory involves the nonlinear\nelasticity characteristics of the vessel wall, and provides predictions for the\nconditions under which the cylindrical form of a blood vessel becomes unstable.",
