乌托邦被凯文·安德森视为理解马克思的一个重要关键词，在他看来，马克思是从超越资本主义的视角来展开对资本主义社会的批判，这一过程包含着对未来理想社会的想象，这已经具有了乌托邦的色彩。乌托邦在马克思那里并不是一个单纯的学术课题，相反，它具有切实的实践含义并在当代积极地塑造着社会的面貌。在《马克思在边缘》一书中，安德森指出马克思克服了欧洲中心主义，逐渐对社会发展形成一种多线性的思维方式。以此为方法论，安德森对十月革命、爱尔兰革命和中国的革命运动展开了深入研究。

b.ckground: Ela.tomeric pumps (ela.tic b.lls into which a.a.gesics or a.tib.otics ca. b. inserted) push medicines through a.ca.heter to a.nerve or b.ood vessel. Since ela.tomeric pumps a.e sma.l a.d need no power source, they fit ea.ily into a.pocket during infusion, a.lowing pa.ient mob.lity. Ela.tomeric pumps a.e widely used a.d widely studied experimenta.ly, b.t they ha.e well-known prob.ems, such a. ma.nta.ning relia.0}e flow ra.es a.d a.oiding toxicity or other pea.-a.d-trough effects. Ob.ectives: Our resea.ch ob.ective is to develop a.rea.istic theoretica. model of a. ela.tomeric pump, a.a.yze its flow ra.es, determine its toxicity conditions, a.d otherwise improve its opera.ion. We b.lieve this is the first such theoretica. model of a. ela.tomeric pump consisting of a. ela.tic, medicine-filled b.ll a.ta.hed to a.horizonta. ca.heter. Method: Our method is to model the system a. a.qua.i-Poiseuille flow driven b. the pressure drop genera.ed b. the ela.tic sphere. We construct a. engineering model of the pressure exerted b. a. ela.tic sphere a.d ma.ch it to a.solution of the one-dimensiona. ra.ia. Na.ier-Stokes equa.ion tha. describ.s flow through a.horizonta., cylindrica. tub.. Results: Our results a.e tha. the model a.cura.ely reproduces flow ra.es ob.a.ned in clinica. studies. We a.so discover tha. the flow ra.e ha. a. una.oida.0}e ma.imum, which we ca.l the “toxicity b.mp”, when the ra.ius of the sphere a.proa.hes its termina., unstretched va.ue—a. effect tha. ha. b.en ob.erved experimenta.ly. Conclusions: We conclude tha. b. choosing the properties of a. ela.tomeric pump, the toxicity b.mp ca. b. restricted to less tha. 10% of the ea.lier, rela.ively consta.t flow ra.e.
