Pregnant cows and heifers were vaccinated with a crude K99 extract prepared from an Escherichia coli K-12, K99 strain. A similar group, injected with an extract prepared from the K-12 parent strain, served as a control. Eleven calves were born to both groups and challenged orally with a mean of 1.6 x 10(11) bacteria of enterotoxic E. coli B41 (O101:K99+, ST+) at the time of first colostrum upta...

This paper introduces an epistemic model of a boundedly rational agent under the two assumptions that (i) the agent’s reasoning process is in accordance with the model but (ii) the agent does not re‡ect on these reasoning processes. For such a concept of bounded rationality a semantic interpretation by the possible world semantics of the Kripke (1963) type is no longer available because the de…...

Introduction: The quality of CT images used for treatment planning of cancer patients is an important issue in accurate outlining of the tumor volume and organs at risk. Different kernels in CT scanner systems are available for improving the image quality. Applying these kernels  on   CT  images  will  change   the   CT  numbers  and  electron   density   of   tissues, conse...

We argue that the Soros account of reflexivity does not provide a clear-cut distinction between a social science such as economics and the physical sciences. It is pointed out that the participants who attempt to learn from refutations of conjectures in the Soros world are likely to be haunted by the Duhem-Quine problem of conjointness of hypotheses and unfocussed refutation. On a more construc...

Christina and David Romer’s paper ‘Does Monetary Policy Matter?’ advocates the so-called ‘narrative’ approach to causal inference. We demonstrate that this method will not sustain causal inference. First, it is impossible to distinguish monetary shocks from oil shocks as causes of recessions. Second, a world in which the Fed only announces intentions to act cannot be distinguished from one in w...

The low energy effective theory of the edge excitations in the Fractional Quantum Hall (FQH) states is proposed. The edge excitations are shown to form a new kind of state which is called the Chiral Luttinger Liquid (χLL). The effective theory is exactly soluble. This enables us to easily calculate all the low energy properties of the edge excitations. We calculate the electron propagator and t...

The major surface glycoprotein (MSG) of Pneumocystis carinii f. sp. carinii consists of a heterogeneous family of proteins that are encoded by approximately 100 unique genes. A genomic expression library was screened with a panel of MSG-specific monoclonal antibodies (MAbs) to identify conserved and rare epitopes. All of the antibodies reacted with epitopes that are encoded within the 5' end of...
