    Notes: Summary To establish a reliable procedure for the early detection of central nervous system involvement in HIV infection, paired cerebrospinal fluid and serum samples of 59 patients were analysed. Fifteen were HIV antibody positive without clinical symptoms (stage I), 12 had lymphadenopathy syndrome or AIDS-related complex (stage II), and 32 had AIDS (stage III). Intrathecal synthesis of HIV antibodies was determined by a modified ELISA. Antibodies in CSF and serum were evaluated at identical immunoglobulin G levels to correct for the actual blood-CSF-barrier permeability. A CSF/serum quotient above 1.5 is indicative of intrathecal antibody synthesis, which was found in 47% of the patients in stage I, 67% in stage II, and 84% in stage III. These findings indicate an early and frequent invasion of the CNS.

    Notes: Summary Combined medical, neurological, and serological investigations were carried out in 59 patients infected with human immunodeficiency virus (HIV). In stage I clinical and neuropsychiatric testing did not reveal evidence for HIV encephalitis as diagnosed by local antibody production in CSF. Neuropsychiatric abnormalities, brain atrophy, memory and cognitive impairment reliably indicated HIV encephalitis in later stages. The commonest symptoms were cerebellar and brainstem signs, followed by dementia. Epileptic fits and hemipareses always were associated with cerebral toxoplasmosis. A polyneuropathy was frequently found but other causes have to be considered.

    Notes: Abstract A general strategy is advanced for simplifying nonlinear optimization problems, the “ant-lion” method. This approach exploits shape modifications of the cost-function hypersurface which distend basins surrounding low-lying minima (including global minima). By intertwining hypersurface deformations with steepest-descent displacements, the search is concentrated on a small relevant subset of all minima. Specific calculations demonstrating the value of this method are reported for the partitioning of two classes of irregular but nonrandom graphs, the “prime-factor” graphs and the “pi” graphs. We also indicate how this approach can be applied to the traveling salesman problem and to design layout optimization, and that it may be useful in combination with simulated annealing strategies.

    Notes: Abstract A brief review of the conceptual difficulties met by the quantum formalism is presented. The main attempts to overcome these difficulties are considered and their limitations are pointed out. A recent proposal based on the assumption of the occurrence of a specific type of wave function collapse is discussed and its consequences for the above-mentioned problems are analyzed.
