Line breaking and page breaking

In their seminal paper of 1981, Knuth and Plass described how to apply the method of discrete dynamic programming to the problem of breaking a paragraph into lines. This paper outlines how the same method can be applied to the problem of page make up, or in other words breaking paragraphs into pages. One of the key ideas is that there must be interaction between the line breaking and page break...

Monitoring Methane

Seed dormancy-breaking and germination requirements of

Dormancy breaking and germination requirements were investigated in seeds of Ferula ovina and Ferula gummosa. Seeds of rather species were collected from north and eastern-north rangelands of Iran. Seeds of each of the species were subjected to different treatments including various levels of GA3, chilling and combination of GA3 and chilling (GA-chilling). In contrast to treated seeds, non-trea...

Quasielastic electron scattering from methane, methane-d4, methane-d2, ethylene, and 2-methylpropane.

Quasielastic electron scattering from gaseous species at high momentum transfer was recently reported for the first time [Cooper et al., J. Electron Spectrosc. Relat. Phenom. 155, 28 (2007)]. The first results for CH(4) and CD(4) were well explained by a classical electron Compton scattering picture in which the electron scatters independently from each atom rather than the molecule as a whole....
