Similarly to the classical sequence alignment problem, the goal of the SAF problem is to find an alignment of several RNA strings, and in addition to find a common folding for the aligned segments of the strings.
Some decades later, mathematician Jean Le Rond d'Alembert generalised the string problem to write down the wave equation, in which he found that the acceleration of any segment of the string was proportional to the tension acting on it.
The steady-state nature of the oscillations and the linear property of the infinite periodic structure allows one to consider just one segment of the string between the neighbouring suspensions.
In other words, motion is transferred from the inner one to the outer one along the segment of the string joining them.
No contact means that the tubular string suspends between connectors and does not touch the inner surface of the wellbore, point contact means that the tubular string touches the wellbore at a single point, and wrap contact means that a segment of the tubular string is in continuous contact with the wellbore.
If the segmentation account is correct, then listeners should encounter difficulties segmenting the string of sounds consisting of the and the initial sound(s) of the target item.
Drilling of the wellbore is accompanied by string casing installations whereby segments of string casing pipes are placed as drilling continues towards the target zone.
Tamarins (Saguinus oedipus) and rats (Rattus rattus), for instance, both respond more strongly to segments of a string with high co-occurrence (Hauser et al. 2001; Toro and Trobalon 2005).
Each individual tree consists of 47 sequences that comprise segments of each concatenate string used for the tree shown in Figure 2. Included among the concatenates are proteins of LGT origin (from Helicobacter pylori, Corynebacterium glutamicum, and Corynebacterium diptheriae) that function for primary Trp biosynthesis.
In the second segment of "The Elegant Universe," string theory comes to the rescue as a bridge between these warring poles of 20th-century physics.
