The setup of the problem: To develop a mathematical model of cerebral cortical folding development, half-hemisphere geometry is used and the outer layer (gray matter) is allowed to move inward under the effect of both physical and biochemical factors. The model is time-dependent, ... Mehr lesen
Pancreatic cancer is one of the deadliest cancers, with a 7% survival rate at five years from diagnosis. The limited number of treatment options for patients who are diagnosed with late-stage disease is a major contributor to this problem. Therapeutic modalities such as radiofrequency ... Mehr lesen
Introduction: Discovering therapeutic drugs that target renal disease is a challenge due to the adverse effects not detected until late in drug development [1]. Preclinical drug studies in animals and static human cell cultures fail to characterize <em>in vivo</em> renal ... Mehr lesen
Microencapsulation-based drug delivery has paved the way for the next generation of drug carrier systems that can deliver a therapeutic agent in a programmable fashion. In this method, therapeutic agent is encapsulated within a microparticle and delivered through hypodermic needles to ... Mehr lesen
Porous scaffolds of natural and synthetic polymers and ceramics, fabricated by electrospinning, salt leaching and 3D printing, are widely used for tissue engineering and regeneration (<em>1</em>). The geometric characteristics of a porous scaffold, such as pore size and ... Mehr lesen
Magnetic insertion of a cochlear implant can reduce intracochlear physical trauma by 50% compared to traditional manual insertion. The magnet attached to the tip of the cochlear implant electrode array must be detached and removed after surgery. This detachment process requires Joule ... Mehr lesen
The quantitative value of electrical bio impedance in tissue structures is sensitive to changes in ionic concentration, frequency and dispersion but lacks specificity. It is difficult to a create a physical measurement set up of clinical value capable of quantifying the contribution of ... Mehr lesen
Temperature changes in the body have been recognized as an indicator of illness for centuries and localized temperature variations due to inflammatory or ischemic events are common in a great variety of diseases. In the case of cancerous breast tumors the increased cell growth rate ... Mehr lesen
高分子囊泡是一类由薄膜包裹液体而形成的“软粒子”，其在生物医药、化妆品以及食品等领域具有广泛的应用，是材料领域最富有意义的研究内容之一。与一般微纳米粒子相比，高分子囊泡在外场作用下极易发生形变，因而研究高分子囊泡在微流道中穿过受限孔洞的动力学行为对其在药物输运、细胞筛选、薄膜性能表征等应用领域具有重要的意义。 由于流体（高分子囊泡内部和外部流体）和固体（高分子囊泡膜）强烈地耦合在一起，再加上流体与膜边界的移动和变形，使得高分子囊泡实际的过孔图像十分复杂。本工作借助COMSOL Multiphysics流固耦合（FSIs）接口，运用任意拉格朗日-欧拉（ALE）算法 ... Mehr lesen
对于神经性听力缺陷患者而言，人工耳蜗是目前主要的恢复手段。人工耳蜗通过植入体内的电极阵列产生电流，直接刺激耳蜗的螺旋神经节细胞，引起听觉系统响应。因此，研究植入耳蜗内电极阵列产生的电势分布特点具有重要意义。基于电势分布情况，可以对电极阵列的结构、尺寸、激励方式等进行优化，以提高人工耳蜗的性能。研究中使用的耳蜗以及电极阵列仿真模型为经过其他三维建模软件得到的STL文件导入COMSOL中生成。为了研究耳蜗内电势分布，选择了“电流（ec）”物理场接口，对模型边界设置了电势条件，对部分电极设置了激励电流条件。仿真模型的材料使用了库材料和自定义材料 ... Mehr lesen
