It is well known that an equilibrium in the Arrow-Debreu model may fail to exist if a very restrictive condition called the survival assumption is not satis ed. We study two approaches that allow for the relaxation of this condition. Danilov and Sotskov (1980), and Florig (1998a) developed a concept of a generalized equilibrium based on a notion of hierarchic prices. Marakulin (1988, 1990) prop...

Arbitrary Arrow Update Logic with Common Knowledge (AAULC) is a dynamic epistemic logic with (i) an arrow update operator, which represents a particular type of information change and (ii) an arbitrary arrow update operator, which quantifies over arrow updates. By encoding the execution of a Turing machine in AAULC, we show that neither the valid formulas nor the satisfiable formulas of AAULC a...

Overview This contribution gives a short introduction to arrow logic We start by explaining the basic idea underlying arrow logic and the motivation for studying it sections and We discuss some elementary duality theory between arrow logic and the algebraic theory of binary relations section In the sections and we give a brief survey of the theory that has been developed on the semantics de nab...

Virulence of Newcastle disease virus (NDV) is mainly determined by the amino acid sequence of the fusion (F0) protein cleavage site. Full-length NDV cDNA clone pNDFL was used to generate infectious NDV with defined mutations in the F0 cleavage site (RRQRR downward arrow L, GRQGR downward arrow F, RRQGR downward arrow F, RGQRR downward arrow F and RKQKR downward arrow F). All the mutants were vi...

T1 coronal images show homogenous hyperintense lesion involving the right trigeminal nerve root (white arrows) in A and B and Meckel’s cave (white arrow) in C as compared to normal left trigeminal nerve (black arrows) and Meckel’s cave (yellow arrow). Axial T1 image also demonstrates the involvement ofmandibular division in foramen ovale (white arrow) as compared to normal on left side (orange ...

We studied numerically the validity of the fluctuation relation introduced in Evans et al. [Phys. Rev. Lett. 71, 2401-2404 (1993)] and proved under suitable conditions by Gallavotti and Cohen [J. Stat. Phys. 80, 931-970 (1995)] for a two-dimensional system of particles maintained in a steady shear flow by Maxwell demon boundary conditions [Chernov and Lebowitz, J. Stat. Phys. 86, 953-990 (1997)...

We study the Fermi gas at unitarity and at T=0 by assuming that, at high polarizations, it is a normal Fermi liquid composed of weakly interacting quasiparticles associated with the minority spin atoms. With a quantum Monte Carlo approach we calculate their effective mass and binding energy, as well as the full equation of state of the normal phase as a function of the concentration x=n downwar...

Fig. 1.-A, Noncontrast CT scan shows vague area of increased attenuation adjacent to head of right caudate nucleus (arrow). B, Coronal T1-weighted (700/ 20/ 4) MR image shows area of decreased signal in white matter adjacent to, and extending into, head of right caudate nucleus (arrow). C, Axial T1-weighted (600/ 20) postcontrast MR image shows no significant contrast enhancement (arrow). D, Ax...
