Thin film lithium niobate optical waveguides for integrated optics
(1992)
Highly oriented polycrystalline thin films of lithium niobate on (012), (100), and (110) sapphire single crystal substrates, (111) silicon and SiO$\sb2$/(100)Si wafers were grown by magnetron rf sputtering and metallo-organic ...
Growth of ferroelectric thin films through metallo-organic decomposition
(1992)
The objective of this investigation is to grow films with good electrical and optical properties through the process of metallo-organic decomposition (MOD) and compare them with those made with other processes such as ...
Conduction in a bullfrog atrial trabeculum: Active and passive properties, and modifications produced by acetylcholine
(1992)
A model of $\beta$-adrenergic and muscarinic cholinergic stimulation of the bullfrog atrial myocyte has been developed that mimics the dose-dependent effects of isoprenaline (ISO) on the action potential duration (APD); ...
Metabolic characterization of T cell lymphoblastoid, Jurkat, in the presence of respiration inhibitors in a continuous reactor
(1992)
Commercial scale mammalian cell culture systems have many technical barriers: (i) accumulation of inhibitory waste products; (ii) sensitivity to low level of shear; and (iii) cellular oxygen demand in excess of bioreactor's ...
Mathematical modeling of the sinoatrial node cell in the rabbit heart
(1992)
A mathematical model has been developed for the rabbit sinoatrial node (SAN) cardiac pacemaker cell, that is based on experimental results from whole-cell voltage clamp and action potential studies on single enzymatically-isolated ...
An ionic current model for neurons in the rat medial nucleus tractus solitarius receiving sensory afferent input
(1992)
An ionic current model has been developed for the rat medial nucleus tractus solitarius (mNTS) neuron that provides a quantitative description of the ionic macrocurrents present in the soma of the cell, and their interaction ...
Micromechanical modeling of elastic-plastic porous materials using finite element analysis
(1992)
Elastic-plastic behavior of porous materials is analyzed using a hollow sphere micromodel and the NIKE2D finite element program. Surface average responses are computed for several displacement controlled homogeneous loadings. ...
Clusters as models of bulk surfaces and novel materials
(1992)
Studies on gas phase clusters show that common ground exists between clusters and bulk surfaces such that clusters can serve as models of bulk surfaces. Several cluster systems are studied to probe this cluster-surface ...
The hardness and modulus of molybdenum silicide/niobium microlaminates and stressed materials determined by nanoindentation
(1992)
Nanoindentation techniques have been used to explore the hardness and elastic modulus of Nb/MoSi$\sb2$ microlaminates and stressed aluminium and stainless steel alloys. The elastic moduli of the microlaminates fall on the ...
