We mainly study the growth and Gelfand-Kirillov dimension (GK-dimension) of generalized Weyl algebra (GWA) $A=D(\sigma,a)$ where $D$ is a polynomial or Laurent algebra. Several necessary sufficient conditions for $\operatorname{GKdim}(A)=\operatorname{GKdim}(D)+1$ are given. In particular, we prove dichotomy GK-dimension GWAs over in two indeterminates, namely, $\operatorname{GKdim}(A)$ either ...

and ν◦ tRt,:α ◦ = 0 for every t. It should be emphasized that relation (18) holds true only in the case where the solution satisfies mink |X :,Gkφ ◦ :,Gk |2 6= 0, otherwise one has to replace it by the condition stating that the null vector belongs to the subdifferential. Since this does not alter the proof, we prefer to proceed as if everything was differentiable. On the one hand, (φ◦,α◦) sati...

Members of the postsynaptic density-95 (PSD-95)/SAP90 family of membrane-associated guanylate kinase (MAGUK) proteins function as multimodular scaffolds that organize protein-signaling complexes at neuronal synapses. MAGUK proteins contain PDZ, Src homology 3 (SH3), and guanylate kinase (GK)-like domains, all of which can function as sites for specific protein-protein interactions. We report he...

ABSTRACT Russin, J. S., Guo, B. Z., Tubajika, K. M., Brown, R. L., Cleveland, T. E., and Widstrom, N. W. 1997. Comparison of kernel wax from corn genotypes resistant or susceptible to Aspergillus flavus. Phytopathology 87: 529-533.Kernels of corn genotype GT-MAS: gk are resistant to Aspergillus flavus. Earlier studies showed that this resistance is due in part to kernel pericarp wax. Experiment...

Herpes simplex virus 1 (HSV-1) glycoprotein K (gK) is expressed on virions and functions in entry, inasmuch as HSV-1(KOS) virions devoid of gK enter cells substantially slower than is the case for the parental KOS virus (T. P. Foster, G. V. Rybachuk, and K. G. Kousoulas, J. Virol. 75:12431-12438, 2001). Deletion of the amino-terminal 68-amino-acid (aa) portion of gK caused a reduction in effici...

To explore the role of calcium in mediating the action of carbachol in chloride-secreting epithelia, we simultaneously measured intracellular free [Ca] ([Ca]i) and the potassium conductance (gK) of the basolateral membrane in T84 cells grown on collagen-coated filters. [Ca]i was measured with fura-2 and fluorescence microscopy and expressed as a relative value ([Ca]'i) normalized to control. To...

This paper presents a new option that can be used by agents for managing foreign exchange risk. Unlike the Garman Kolhagen model [1], (GK), this paper presents a new model with a preset exchange rate (PE), that allows the agent to take advantage of the his/her view on both the direction and magnitude of rate movement and as such provides this agent with more choices. The model has a provision f...

For a graph G and a unary graph operation X, there is a graph sequence {Gk} generated by G0 = G and Gk+1 = X(Gk). Let Sp(Gk) denote the set of normalized Laplacian eigenvalues of Gk. The set of limit points of ⋃∞ k=0 Sp(Gk), lim infk→∞ Sp(Gk) and lim supk→∞ Sp(Gk) are considered in this paper for graph sequences generated by two operations: subdivision and triangle extension. It is obtained tha...

Glucokinase (GK) is the rate-limiting enzyme in the glycolytic pathway of the b-cell and, even in the rat fetus at 22-days gestation, immediately before birth, acts as a sensor of glucose influencing the rate of glucose utilization. However, when GK first appears in islets during b-cell development is unknown. Whether GK is expressed in fetal glucagon-producing cells is also unknown. To determi...

Let R be a discrete valuation ring with fraction field K and X a flat R-scheme. Given a faithful action of a K-group scheme GK over the generic fibre XK , we study models G of GK acting on X. In various situations, we prove that if such a model G exists, then there exists another model G′ that acts faithfully on X. This model is the schematic closure of G inside the fppf sheaf AutR(X) ; the maj...
