The concept of lethality is essential to the assessment of suicide risk; yet operational definitions of lethality for purposes of its measurement have been loose and varied. A number of scaling measures have been published in the literature, with no relative consensus on the best of these. In addition, only a few of these scales have published data on their psychometric properties. Of these, we...

I N yeast, more dominant lethality is induced in diploid than in haploid vegetative cells (OWEN and MORTIMER 1956), and this is consistent with the observed increase in X-ray sensitivity of cells of higher ploidy in this organism ( MORTIMER 1958). To study dominant lethality with respect to ploidy in a higher organism, the parasitic wasp Mormoniella was selected. Stocks are available which prod...

In this paper, we model the method in which aircraft survivability equipment suites successfully choose their countermeasures, and experiment with their autonomous decision-making against threats in various electronic warfare settings. We have designed and implemented our simulators to estimate the operational effectiveness of the aircraft survivability equipment suite. We formulate the operati...

The thermal conductivity of superconducting MgB 2 was studied in both the superconducting and normal state region. The latter is almost equally determined by the electronic-and the lattice thermal conductivity. In the superconducting state, however, the lattice thermal conductivity is larger. The electronic thermal conductivity below T c was derived from the experimental data considering the Ba...

Mutations in the gene drop-dead (drd) cause diverse phenotypes in adult Drosophila melanogaster including early lethality, neurodegeneration, tracheal defects, gut dysfunction, reduced body mass, and female sterility. Despite the identification of the drd gene itself, the causes of early lethality and neurodegeneration in the mutant flies remain unknown. To determine the pattern of drd expressi...
