The malic enzyme from Halobacterium cutirubrum requires monovalent cations for both activation and stabilization. NaCl, the best stabilizer, is ineffective as activator; NH(4)Cl, the best activator, is a poor stabilizer. These results support the idea that the roles of salts in both processes are different.

Let A be a finite dimensional complex vector space with a polynomial action of G = GLk. One main example is A = Sym C. (For tensors G = GLk, A = ⊗C) Let Z ⊆ A be locally closed. One main example is a group orbit Z = Gv. Recall (last semester, Chapter 15) that for a locally closed set Z ⊆ A we defined the coordinate ring C[Z] as the ring of regular functions (i.e., locally defined by rational fu...

We consider closed, Weyl-transitive groups of automorphisms of thick buildings. For each element of such a group, we derive a combinatorial formula for its scale and establish the existence of a tidy subgroup for it that equals the stabilizer of a simplex. Simplices whose stabilizers are tidy for some element of the group are characterized in terms of the minimal set of the isometry induced by ...

In this paper nondegenerate multidimensional matrices of boundary format in V0 ⊗ · · · ⊗ Vp are investigated by their link with Steiner vector bundles on product of projective spaces. For any nondegenerate matrix A the stabilizer for the SL(V0)×· · ·×SL(Vp)action, Stab(A), is completely described. In particular we prove that there exists an explicit action of SL(2) on V0 ⊗ · · · ⊗ Vp such that ...

This paper considers the nucleation and propagation of a normal zone in large composite superconductors, considering the relatively tong time of current redistribution in the stabilizer. A model is proposed for treating the composite as an effective electrical circuit, which yields two diffusion equations for the electric current and the temperature distributions along the conductor. Numerical ...

Self-orthogonal J-affine variety codes have been successfully used to obtain quantum stabilizer codes with excellent parameters. In a previous paper we gave formulae for the dimension of this family of quantum codes, but no bound for the minimum distance was given. In this work, we show how to derive quantum stabilizer codes with designed minimum distance from J-affine variety codes and their s...

The perceived motion of two added sinusoidal gratings of similar amplitude and spatial frequency but different orientations is often coherent. However, when either relative grating contrast or frequency are varied, perception may transform to a motion transparency. For plaids, both multiplicative and additive transparent percepts are reported. To explain perception, several computational models...

This study aimed to develop natural colorant tomato powder using foam mat drying method varying egg albumin (3, 5, and 7% w/w) as foaming agent, carboxymethyl cellulose (0.5% 1%) stabilizer concentrations dried at three various temperatures (60, 65, 70 °C). The properties of juice were analyzed. Foams prepared juice, incorporating (EA), (CMC), whipped thoroughly maximum speed for about 5 min. s...

This thesis is an exposition of a classification of classical reversible gates acting on bits in terms of the reversible transformations they generate, which was recently completed by the author, Scott Aaronson, and Luke Schaeffer. In particular, we present those portions of the classification which were the main contributions of the author. Most importantly, this thesis contains the proof that...

In this note we show that the nth Morava E-cohomology group of a finite spectrum with action of the nth Morava stabilizer group can be recovered from the (n + 1)st Morava Ecohomology group with action of the (n + 1)st Morava stabilizer group.
