Temperature is an important physiological variable the influence of which on macroscopic electrophysiological measurements in slices is not well documented. We show that each of three voltage-sensitive conductances of octopus cells of the mammalian ventral cochlear nucleus (VCN) is affected differently by changes in temperature. As expected, the kinetics of the currents were faster at higher th...

Previous studies have suggested that the human autonomic nervous system responds to stimuli 2–3 seconds before presentation. In these studies randomly chosen photographs with high and low affectivity were presented to participants.Ensemble averaging of skin conductance in the prestimulus epochs showed a differential response between high and low affectivity photographs. In our protocol the prob...

Two-dimensional materials and their heterostructures have emerged as a new class of materials, not only for fundamental physics but also for electronic and optoelectronic applications. Black phosphorus (BP) is a relatively new addition to this class of materials. Its strong in-plane anisotropy makes BP a unique material for making conceptually new types of electronic devices. However, the globa...

Energetics and quantized conductance in jellium-modeled nanowires are investigated using the localdensity-functional-based shell correction method, extending our previous study of uniform-in-shape wires @C. Yannouleas and U. Landman, J. Phys. Chem. B 101, 5780 ~1997!# to wires containing a variable-shaped constricted region. The energetics of the wire ~sodium! as a function of the length of the...

Submitted for the MAR06 Meeting of The American Physical Society Conductance Behavior of Molecularly Linked Gold Nanoparticle Films Near the Metal-Insulator Transition JEFFREY DUNFORD, YOSHINORI SUGANUMA, AL-AMIN DHIRANI, BRYAN STATT, University of Toronto — Self-assembled molecularly-linked metal nanoparticle films exhibit interesting electronic behavior that can range from insulating to metal...

Impedance measurements in whole lenses showed that lens fiber cells possess different permeability properties to the epithelial cells from which they differentiate. To confirm these observations at the cellular level, we analyzed the membrane properties of fiber cells isolated in the presence of the nonselective cation channel inhibitor Gd3+. Isolated fiber cells were viable in physiological [C...

The response to inhaled sulphur dioxide in eight normal, seven atopic, and 22 asthmatic subjects was studied by measuring thoracic gas volume and airway resistance in a whole-body plethysmograph. The fall in specific airway conductance in relation to the concentration of sulphur dioxide inhaled (0-20 ppm) was determined in all three groups. The specific airway conductance fell significantly in ...

We present a single-electron device for the manipulation of charge states via quantum interference in nanostructured electrodes. Via self-inductance effects, we induce two independent magnetic fluxes electrodes and demonstrate sensitivity to single field at variable temperature. Moreover, our approach allows us local control single-particle conductance between nano-engineered tunnel junctions f...
