Abstract: System and method to improve the linearity of vector matrix multipliers (VMMs) by including (1) delta-sigma modulators that convert the input and output activations into binary pulse trains, (2) charge-domain computation in each SRAM cell that removes the nonlinear dependency on bitline voltage of the result of the multiplication and allows rail-to-rail output swing, and (3) a CMOS switch that transmits input activation to the capacitor in the SRAM cell, which improves linearity by suppressing the switch threshold voltage dependence on input activation voltage.

Abstract: Provided is a method of inhibiting protein kinase C zeta/protein kinase M zeta, including contacting a sample containing an isoform of protein kinase C zeta with a compound of formula: referred to as 1-naphthol-3,6,8-trisulphonic acid, or a pharmaceutically acceptable salt thereof. In some embodiments, contacting the sample with the compound does not inhibit protein kinase C iota/lambda. In a specific example, the sample includes neural tissue, the isoform of protein kinase C zeta is protein kinase M zeta, and inhibiting includes reducing kinase activity and further includes diminishing long-term potentiation. In some embodiment, the method includes inhibiting glucose transport. Also provided is a method of affecting memory, including administering the compounds to a mammalian organism.

Abstract: Disclosed herein are isotopically labeled calcofluor derivatives and uses of such to detect fungi, such as filamentous fungi, including Aspergillus species, such as by positron emission tomography (PET) scanning.

Abstract: Pillared interlayered clay catalysts (PILC) are formed and used in the selective reduction (SCR) of nitrogen oxides (NO.sub.x) in exhaust gases in the presence of ammonia. Cr.sub.2 O.sub.3 -PILC, Fe.sub.2 O.sub.3 PILC, TiO.sub.2 -PILC, ZrO.sub.2 -PILC and Al.sub.2 O.sub.3 -PILC each have considerable activities in the SCR of NO by NH.sub.3. Forming the catalysts in a bimodal pore structure provides increases poison resistance and increases reaction rates. Doping the catalyst with CeO.sub.2 and/or Ce.sub.2 O.sub.3 can promote increased activities. The PILC SCR catalysts do not oxidize SO.sub.2 to undesirable SO.sub.3 in any detectable amount.

Abstract: Biological applications of synthetic and natural alkaloids derived from the tunicate Eudistoma sp. are disclosed. A method regulating cell growth includes contacting one or more cells with an effective concentration of a compound for regulating cell growth. These compounds include: Segoline A, Segoline B, Isosegoline A, Norosegoline, Debromoshermilamine, Eilatin, 4-methylpyrido[2,3,4-kl] acridine, pyrido[2,3,4-kl]acridine, 1-acetyl-2,6-dimethylpyrido[2,3,4-kl]acridine, and derivatives and combinations of these compounds. An effective concentration range for using these compounds can range from approximately 0.1 .mu.M to 100 .mu.M. The effective concentration range for Eilatin, the most potent of these compounds is from 0.01 .mu.M to 0.99 .mu.M, and the effective concentration range for the other compounds of the present invention is from about 1.0 .mu.M to 100 .mu.M.
