Barium strontium titanate thin films are being developed as capacitors in dynamic random access memories. These films, grown on silicon substrates, are under tensile residual stress. By a converse electrostrictive effect, the in-plane tensile stress reduces the capacitance in the thickness direction of the film. We measured the substrate curvature change(More)
Two potent and highly selective nonpeptide antagonists, L-365,031 [1-methyl-3-(4-bromobenzoyl)amino-5-phenyl-3H-1,4 benzodiazepin-2-one] and 3H-L-364,718 [1-methyl-3-(2-indoloyl)amino-5-phenyl-3H-1,4 benzodiazepin-2-one] were used to localize "peripheral" CCK receptors in rat brain. In autoradiographic experiments, L-365,031 displaced 125I-Bolton Hunter(More)
In vitro autoradiography was performed in order to visualize cholecystokinin-A (CCK-A) receptors in sections of Cynomolgus monkey brain. CCK-A receptors were defined as those which displayed high affinity for the selective non-peptide antagonist MK-329 (L-364,718) and were detected in several regions by selective inhibition of 125I-Bolton Hunter CCK using(More)
A comparison of cholecystokinin (CCK) receptor binding to sections of rat, mouse and guinea pig brain has been performed using 125I-Bolton Hunter CCK and the selective peripheral CCK receptor antagonist L-365,031. In both rat and mouse, 125I-Bolton Hunter CCK binding in the region of the interpeduncular nucleus (IPN) was inhibited by L-365,031 indicating(More)
Ultra low-k (ULK, k=2.4) dielectric has weaker mechanical properties than first generation low-k films (k=3.0). The introduction of ULK into advanced back end of lines (BEOL) presents a significant challenge due to chip package interaction (CPI) where the packaged die is cycled over a temperature range and the resulting stress can cause ULK BEOL(More)
Cholecystokinin (CCK) receptor binding was measured in sections of human, monkey and rat spinal cord using autoradiographical techniques. In each species, high levels of specific 125I-Bolton-Hunter CCK binding were detected in the superficial layers of the dorsal horn (the substantia gelatinosa). In monkey and human but not rat spinal cord, 125I-CCK binding(More)
The adoption of ultra-low k dielectric materials in the pursuit of greater performance will pose reliability challenges quite unlike what we have previously experienced. The ultra-low k (ULK) dielectrics are completely different from the materials we have traditionally used. Unfortunately, the properties that make them desirable from an electrical point of(More)
Universal relaxation with, values of n close to 1, has been observed in thin film barium strontium titanate (BST) from 1 mHz to 20 GHz [1]. Although it is not an intrinsic loss mechanism, it is generally dominant at frequencies below 100 GHz [2]. In addition to BST, we have also observed this behavior in strontium titanate and bismuth zinc niobate. Because(More)
Many of the forest soils in the Intermountain West are deficient in several nutrients, including nitrogen (N), potassium (K), sulfur (S) and boron (B) and these deficiencies may impact tree resistance to insect attack. Two potential techniques for manipulating tree resistance are fertilization and thinning. We examined fertilization (both alone and in(More)
The results of a series of replicated fertilization trials established throughout the Inland Northwest were reviewed for information specific to ponderosa pine (Pinus ponderosa P. and C. Lawson) nutrition. Ponderosa pine nitrogen (N) status was often better than the N-status of other Inland Northwest species, and therefore growth response to N fertilization(More)
