We tested the hypothesis that a conduction pathway intrinsic to the arteriolar wall possesses the properties necessary to coordinate vasomotor responses in the microcirculation. Acetylcholine (ACh) or norepinephrine (NE) was iontophoresed onto cheek pouch arterioles (15-35 microns diam) of pentobarbital-anesthetized hamsters, and diameter responses were observed using intravital video microscop...

From the theory of an electric network containing any combination of resistances and a single variable impedance element having a constant phase angle independent of frequency, it is shown that the graph of the terminal series reactance against the resistance is an arc of a circle with the position of the center depending upon the phase angle of the variable element. If it be assumed that biolo...

While resistance has long been discussed as an obstacle to the process of psychotherapy (Freud, S., 1912,1914; Freud, A., 1936; Fenichel, 1945; Gill, 1963; Greenson, 1967) it has been less frequently addressed in the context of psychotherapy supervision. The most frequent aspect of resistance in supervision that has been discussed in the literature is the type of resistant behavior most commonl...

A two-terminal memristor memory based on a single VO2 nanowire is reported that can not only provide switchable resistances in a large range of about four orders of magnitude but can also maintain the resistances by a low bias voltage. The phase transition of the single VO2 nanowire was driven by the bias voltage of 0.34 V without using any heat source. The memristive behavior of the single VO2...

Ž . The anodic polarization process in metal-hydride electrodes occurs via the following consecutive steps: i diffusion of absorbed Ž . hydrogen from the bulk to the surface of the electrode, ii hydrogen transfer from absorbed state to adsorbed state at the electrode Ž . surface, and iii electrochemical oxidation of the adsorbed hydrogen on the electrode surface. A theoretical treatment is pres...
