Multitree automata that count
Multitree are unranked, unordered trees and occur in many Computer Science applications like rewriting and logic, knowledge representation, XML queries, typing for concurrent systems, cryptographic protocols.... We define constrained multitree automata which accept sets of multitrees where the constraints are expressed in a first-order theory of multisets with counting formulas which is very ex...
متن کاملWords that heal.
The value of words in the healing process runs constant to the path of therapeutic treatment, the net of exchanges and relationships between brain chemistry and the right words in order to heal is subtle and intricate. Psychotherapy, a treatment with words, is shown to be a treatment that directly affects the brain and that is able to change it stably, even in its anatomical structure and funct...
متن کاملSynthetic gene networks that count.
Synthetic gene networks can be constructed to emulate digital circuits and devices, giving one the ability to program and design cells with some of the principles of modern computing, such as counting. A cellular counter would enable complex synthetic programming and a variety of biotechnology applications. Here, we report two complementary synthetic genetic counters in Escherichia coli that ca...
متن کاملGene Silencing Repeats that Count
RIP is nucleus limited. We know this because the specialized cells that carry out RIP are heterokaryotic, with nuclei from both parents. When a sequence is duplicated in one nucleus but not the other, the lone copy is never silenced. The mechanism of RIP is unknown but probably involves DNA:DNA pairing (Figure 1) followed by methyla-Repeated DNA and cytosine methylation are common tion and deam...
متن کاملTo count and how to count, that is the question.
Optimal cancer staging requires retrieval of a minimal number of nodes. However, variability among pathologists in counting on a slide has not been studied. To study the differences in node counting among pathologists, 10 pathologists counted nodes on 15 slides on 2 occasions. They also opined on whether selected "structures" represented countable nodes. There was no slide on which all patholog...
