We study the market implications of ambiguity in many common models. We show that generic determinacy is a robust feature in many general equilibrium models that allow a distinction between ambiguity and risk. JEL Codes: D0, D5, D8, G1

A monopolist supplies a multi-attribute good and does not know whether the consumer makes or avoids tradeoffs between attributes. We illustrate a form of exploitation to which the tradeoff-avoiding consumer is vulnerable. (JEL: D6, D8, L1, L2)

To assess reinfection of BALB/c mice with different Toxoplasma gondii strains, the animals were prime infected with the non-virulent D8 strain and challenged with virulent recombinant strains. Thirty days after challenge, brain cysts were obtained from surviving BALB/c mice and inoculated in Swiss mice to obtain tachyzoites for DNA extraction and PCR-RFLP analysis to distinguish the different T...

Rhythmic surface Electromyographic (sEMG) bursts for which their returns occur at irregular times are analyzed and compared among healthy and injured central nervous systems. The rhythmic electrophysiological activity in the present study has been defined as “Bursting Rate Variability” (BRV) due to the inherent aperiodicity of successive sEMG bursts, which are concomitant with “doublet” wavefor...

In [7] a characterization of transitive permutation groups having a non-self-paired suborbit of length 2 (with respect to which the corresponding orbital graph is connected) was obtained in terms of their point stabilizers. As a consequence, elementary abelian groups were proved to be the only possible abelian point stabilizers arising from such actions, and D8 was shown to be the only nonabeli...

The low-energy supersymmetric quantum mechanics describing D-particles in the background of D8-branes and orientifold planes is analyzed in detail, including a careful discussion of Gauss’ law and normal ordering of operators. This elucidates the mechanism that binds Dparticles to an orientifold plane, in accordance with the predictions of heterotic/type I duality. The ocurrence of enhanced sym...

We propose several quark mass deformations of the holographic model of massless QCD using the D4/D8/D8-brane configuration proposed by Sakai and Sugimoto. The deformations are based on introducing additional D4or D6-branes away from the QCD D4 branes. The idea is similar to extended technicolor theories, where the chiral symmetry breaking by additional D-branes is mediated to QCD to induce non-...

Three isolates of Newcastle disease virus obtained from normal village chickens, which were never vaccinated against Newcastle disease were characterized. These isolates namely D8, D53 and D58 were found to have an ICPI value of 1.59, 0.50 and 0.14 respectively. The deduced amino acid sequence at the FPCS of these three isolates between positions 112 and 119 were G-R-R-Q-K-R-F-I-G-G-R-R-Q-K-R-F...

We discuss chiral symmetry breaking in the intersecting brane model of Sakai and Sugimoto at weak coupling for a generic value of separation L between the flavour D8 and anti-D8-branes. For any finite value of the radius R of the circle around which the colour D4-branes wrap, a non-local Nambu−Jona-Lasinio (NJL) type short-range interaction couples the flavour branes and anti-branes. We argue t...
