  4. 2. Mechanical and Electrical Properties of Mesoscopic Wires

    Author : Sara Blom; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Rabi oscillations; conductance quantization; free electron model; mesoscopic; microwave; channel; force fluctuations; adiabatic; nanowire;

    Abstract : The mechanical and electrical properties of mesoscopic wires have been studied theoretically using a free electron model. When a mesoscopic wire is elongated the conductance decreases in steps. Each step is accompanied by an abrupt change in the force. READ MORE

  5. 3. Patch clamp and calcium studies on human colonic mucosal cells

    Author : Peter Sand; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Human; colon crypt; HT29; K channel; Ca oscillations; volume regulation; patch clamp;

    Abstract : Background: The main function of the large intestine is to fine-tune electrolyte and water balance. This is achieved through the consorted action of ion channels, transporters and pumps. Failures of this system can lead to diarrhoea. READ MORE

  6. 4. Waves and rays in open billiards

    Author : Torbjörn Blomquist; John B. Delos; Linköpings universitet; []
    Keywords : ;

    Abstract : Semiconductor systems where the deBroglie wavelength of the electron is comparable to the size of the system are called mesoscopic. Such systems are readily produced in laboratories, and have been studied extensively. These systems offer possibilities to study the borderline between quantum and classical physics, chaos and more.

  7. 5. Neuromodulation within a spinal locomotor network : role of metabotropic glutamate receptor subtypes

    Author : Petronella Kettunen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : mGluR1; mGluR5; spinal cord; modulation; glutamate; NMDA; leak channel; locomotion; endocannabinoids; lamprey.;

    Abstract : The metabotropic glutamate receptors, mGluRs, are G-protein coupled receptors. They consist of eight cloned subtypes, which are divided into three groups depending on the amino acid sequence similarity, pharmacology and their signal pathways. READ MORE
