What is the role of bacterial exposure in asthma protection and prevention? This topic is receiving increasing attention, particularly based on epidemiological findings relating to the ‘hygiene hypothesis’.

Science Fiction and Macdonald's Polynomials

This work studies the remarkable relationships that hold among certain m-tuples of the Garsia-Haiman modules M and corresponding elements of the Macdonald basis. We recall that in 10], M is deened for a partition`n, as the linear span of derivatives of a certain bihomogeneouspolynomial (x; y) in the variables x 1 ; x 2 conjecturedin 6], 10] that M has n! dimensionsand that its bigraded Frobeniu...

Aggregates of living cells (i.e. model tissue fragments) under appropriate conditions fuse like liquid drops. According to Steinberg's differential adhesion hypothesis (DAH), this may be understood by assuming that cells are motile and tissues made of such cells possess an effective surface tension. Here we show that based on these properties three-dimensional cellular structures of prescribed ...
