For a random-self-reducible function, the evaluation problem is irreducible to the one-moreevaluation problem, in the following sense. An irreduction algorithm exists that, given a re-duction algorithm from the evaluation to the one-more evaluation problem, solves a separatorproblem: the evaluation problem itself. Another irreduction shows that if the computationalDiffie-Hellman...

Constraint-based environments often avoid the complex task of general theorem proving and focus on a well-behaved logical sublanguage. Reintro-duction of the more general facilities is a promising eeort as constraints are now much more eeciently dealt with than in most pure theorem provers and the constraint calculus itself gains expressivity. This paper discusses programming techniques develop...

A complex set of interactions between the microbiome, gut and brain modulate responses to visceral pain. These interactions occur at the level of the gastrointestinal mucosa, and via local neural, endocrine or immune activity; as well as by the pro-duction of factors transported through the circulatory system, like bacterial metabolites or hormones. Various psychological, in-fectious and other ...

Based on the findings that expression of endogenous tumor necrosis factor (enTNF), which is not present in TNF-susceptible cells, was generally observed in TNF-resistant cells and that TNF gene transfection gives rise to TNF resistance, the assumption was made that enTNF may be a protective protein against the cytotoxicity of exogenous TNF. However, it remains unknown whether the protection by ...

We address the problem of nding a subset of features that allows a supervised induc tion algorithm to induce small high accuracy concepts We examine notions of relevance and irrelevance and show that the de nitions used in the machine learning literature do not adequately partition the features into useful categories of relevance We present de ni tions for irrelevance and for two degrees of rel...

Carboxypeptidase is here defined as that en zyme, found in a wide variety of tissues, which hydrolyzes chloracetyl-L-tyrosine, with the pro duction of acid groups and free tyrosine. The dis tribution and properties of this enzyme were recently described by us (1), and it was pointed out not only that two forms of the enzyme can be detected but that there can also be detected a naturally occurri...

The human promyelocytic leukemia cell line HL-60 under goes terminal myeloid differentiation in vitro in response to a wide variety of chemicals. The tumor promoter phorbol myristate acetate induces these cells to develop macrophage-like morphology, adherence, and enzymatic characteristics. The present study confirms those observations and further docu ments the induction, by 16 nM phorbol myri...

9 Recombinant proteins are often purified from microbial lysates containing high concentrations of nucleic acids. Pre-purification 10 steps such as nuclease addition or precipitation with polyethyleneimine or ammonium sulfate are normally required to reduce 11 viscosity and to eliminate competing polyanions before anion exchange chromatography. We report that small polycationic 12 compaction ag...

Brown syndrome is a rare form of strabismus that is characterised by restriction of elevation of the eye in adduction. This is a case report of an eleven year old Nigerian girl who presented with a history of squint and poor vision. She had visual acuities of 6/24 and counting fingers in her right and left eyes respectively. There was a left hypotropia in the primary position of gaze with assoc...
