We consider the inferability of linear single-tree languages. We are able to show that if the terminal productions of the corresponding grammars obey a simple restriction , then the languages generated are inferable from positive samples only. Moreover, we solve an open problem posed by Greibach, Shi, and Simonson concerning the unambiguity of certain ultralinear STG's.

Generation mean analysis was carried out to estimate the nature andmagnitude of gene effects for sugar yield and its component traits in sweet sorghum[Sorghum bicolor (L.) Moench. Six basic generations, namely P1, P2, F1, F2,BC1P1, BC1P2 of four crosses involving seven diverse parents were evaluated inrainy 2009. The mean performance of the F1 in all the crosses indicated dominantgene effect fo...

abstract effect of selection index in four iranian commercial lines (107, 110, 153 and 154) on performance of their hybrids including 107 ×110, 110×107, 153×154 and 154×153 was investigated. selection index program was performed on all 3p commercial lines during 9 generations. next generation parents of 3p lines were selected in each generation, by construction of selection matrix based on heri...

0800 – 0930 OPENING CEREMONIES KEYNOTE SPEAKER Leveraging Generational Diversity in a Healthcare setting For the first time ever, there are five generations working side by side in our workplaces (soon to be six and seven); each with their own perspectives, experiences, and attitudes. Effectively communicating across generations can be frustrating or exhilarating. Learn skills and techniques th...

Genotypes of 68,230 individuals taken from 10 generations (F(4)-F(6), F(14)-F(17), F(24)-F(26)) of an experimental population of barley were determined for four esterase loci. The results show that frequencies of gametic ditypes changed significantly over generations and that striking gametic phase disequilibrium developed within a few generations for each of the six pairwise combinations of lo...
