Insertion-Deletion Transformer
[article]
2020
arXiv
pre-print
We propose the Insertion-Deletion Transformer, a novel transformer-based neural architecture and training method for sequence generation. ...
We demonstrate the effectiveness of our Insertion-Deletion Transformer on synthetic translation tasks, obtaining significant BLEU score improvement over an insertion-only model. ...
We see our Insertion-Deletion Transformer model outperforms the Insertion Transformer significantly on this task. ...

v-Ha-Ras insertion/deletion mutants with reduced protease-inhibitory activity have no transforming activity
1993
FEBS Letters
We have purified 26 insertion/deletion mutants of v-Ha-ras oncogene products produced by Escherichia coli and investigated their proteaseinhibitory activity toward papain and cathepsins B and L. ...
Among them, four mutants, l-48 LIR , showed significant reduction in the inhibitory activity toward cathepsin L and these four mutants have lost transforming activity toward NIH3T3 mouse fibroblasts. ...
For example, l-2 1 PDQ 37-189 has insertion of Pro-Asp-Gln instead of deletion of the amino acid sequence between positions 22 and 36. ...

Linear Time Additively Exact Algorithm for Transformation of Chain-Cycle Graphs for Arbitrary Costs of Deletions and Insertions
2020
Mathematics
We assume that the double cut and join operations have identical costs, and costs of the deletion and insertion operations are arbitrary strictly positive rational numbers. ...
We propose a novel linear time algorithm which, given any directed weighted graphs a and b with vertex degrees 1 or 2, constructs a sequence of operations transforming a into b. ...
These operations are analogous to standard deletion of a subword in a word and to insertion of a word as a subword. Each operation is assigned with its cost, a strictly positive rational number. ...

Deletions and insertions within an amino-terminal domain of pp60v-src inactivate transformation and modulate membrane stability
1989
Journal of Virology
In addition, insertion of four, but not one, amino acid residues at position 161 also inhibited transformation. ...
Here we report that introduction of small (tri-and tetrapeptide) deletions into a region of pp6O-src containing amino acid residues 155 to 175 was found to inactivate transformation. ...
We report here that trior tetra-amino acid deletions or insertions within the region defined by residues 155 to 177 abrogated pp60v-src transformation of CE cells. src proteins encoded by these deletion ...

Deletion and insertion mutations in early region 1a of type 5 adenovirus that produce cold-sensitive or defective phenotypes for transformation

Journal of Virology
On the basis of earlier findings showing that H5hr1 (hr1) is cold sensitive for transformation, a series of mutants were constructed so that they contained deletions or insertions in different sites of ...
It is striking, however, that a mutant (H5dl105) with a 69-base pair deletion beginning at nucleotide 1,003, and having a stop codon at nucleotide 1,544, was totally defective for transformation at any ...

Mapping of transforming region of the Harvey murine sarcoma virus genome by using insertion-deletion mutants constructed in vitro
1980
Proceedings of the National Academy of Sciences of the United States of America
By using the cloned Ha-MuSV DNA insert as a parental genome, we have constructed a series of insertion-deletion mutants by inserting an octomer containing the Sal I linker sequence (C-G-T-C-A-C-C) into ...
However, a mutant containing a deletion of 1.5kb at the 5'-end and a mutant with a deletion of the sequences between 1.0 and 1.5 kb from the 5'-end completely lost their transforming potential. ...

Simultaneous editing of JSON objects via operational transformation

Proceedings of the 31st Annual ACM Symposium on Applied Computing - SAC '16
For the synchronization of the changes a replication system named Operational Transformation is used. Such a system consists of a control algorithm and a transformation function. ...
In this work we investigate on the correctness of such transformation functions. ...
