In wild-type S. cerevisiae, diploid cells must be heterozygous at the matingtype locus in order to sporulate. In the preceding paper, we described a number of mutants (CSP mutants), isolated from nonsporulating aa and aa parent strains, in which sporulation appeared to be uncoupled from control by mating type. The characterization of one of these mutants (CSPI) is now extended to other processe...

The yeast TEL1 and MEC1 genes (homologous to the mammalian ATM and ATR genes, respectively) serve partially redundant roles in the detection of DNA damage and in the regulation of telomere length. Haploid yeast tel1 mec1 strains were subcultured nonselectively for approximately 200 cell divisions. The subcultured strains had very high rates of chromosome aberrations: duplications, deletions, an...

We present a novel, real-time algorithm for computing the continuous penetration depth (CPD) between two interpenetrating rigid models bounded by triangle meshes. Our algorithm guarantees gradient continuity for the penetration depth (PD) results, unlike conventional penetration depth (PD) algorithms that may have directional discontinuity due to the Euclidean projection operator involved with ...

With the increasing availability of remote sensing images, regularization jagged building outlines extracted from high-resolution images has become a current research hotspot. Based on an existing method proposed earlier by this author for extracting skeleton lines buildings through integrating vector and raster data using as input data, new is here regularizing combining with Minkowski additio...
