This paper gives an equational axiomatization of probabilistic bisimulation equivalence for a class of finite-state agents previously studied by Stark and Smolka ((2000) Proof, Language, and Interaction: Essays in Honour of Robin Milner, pp. 571–595). The axiomatization is obtained by extending the general axioms of iteration theories (or iteration algebras), which characterize the equational p...

Trans-resveratrol (Resv) was acquired from Sigma-Aldrich (St. Louis, MO, USA). It was tested using the COX fluorescent inhibitor screening assay kit (Cayman, Ann Arbor, MI, USA) according to the authors of Reference [1]. Scalar concentrations (specified in the graphs) of Resv were tested on purified, ovine COX-1 and human recombinant COX-2. The commercial inhibitors SC-560 and DuP-697 active on...

Despite the importance of resource availability, the inclusion of availability awareness in current agentbased systems is limited, particularly in decision support settings. This article discusses issues related to availability awareness in agent-based systems and proposes that knowledge of resources’ online status and readiness in these systems can improve decision outcomes. A conceptual model...

We explore mutual information (MI) as a means of characterizing linguistic statistical structure. The MI between two linguistic tokens x and y is the degree to which seeing x helps us anticipate the occurrence of y. We computed MI between words in 595 samples of written text in 25 languages. Our analyses indicate that MI dependencies do not extend beyond a range of five words. Moreover, the sim...

On April 16, 1999, the Department of Health and Human Services and the United Network for Organ Sharing (UNOS) announced that the number of organ donors increased 5.6 percent in 1998, the first substantial increase since 1995. Donation increases between 1997 and 1998 were substantial for whites (up 6.6 percent from 4,139 to 4,410 donors) and Hispanics (up 7.8 percent from 552 to 595 donors). Ho...

A self-organized In0.53Ga0.47As/(In0.53Ga0.47As)2(In0.44Al0.56As)2 quantum wire (QWR) laser was grown on a (775)B InP substrate by molecular beam epitaxy (MBE). Well lattice-matched and flat cladding layers were grown at a rather high temperature (595 C). Lateral confinement potential was induced by a nano-meter scale interface corrugation of InGaAs/(InGaAs)2(InAlAs)2 with an amplitude of 2 nm ...

Induction parameters including inducer concentration, period of induction and the cell concentration at which inducer is to be added to the fermentation broth were optimized in order to increase the yield of the EcoRI restriction endonuclease isolated from recombinant E. coli. Bacterial cells harboring the plasmid pPG430 containing EcoRI endonuclease and the methylase genes under the control of...

The title compound, C(7)H(6)O(5)·H(2)O, is a new polymorph of the structures reported by Jiang et al. (2000 ▶) [Acta Cryst. C56, 594-595] and Okabe et al. (2001 ▶) [Acta Cryst. E57, o764-o766]. The gallic acid mol-ecule is essentially planar (r.m.s. deviation = 0.550 Å). An intra-molecular O-H⋯O hydrogen bond occurs in the gallic acid mol-ecule, which is linked to the water mol-ecule by a furth...
