Escherichia coli BW25113 is the parent strain of the Keio collection comprising nearly 4,000 single-gene deletion mutants. We report the complete 4,631,469-bp genome sequence of this strain and the key variations from the type strain E. coli MG1655.

This paper considers error-correction for information in array design, i.e., two-dimensional design such as QR-codes. The error model is multi deletion/substitution/erasure errors. Code construction the errors and an application of code are provided. decoding technique uses error-locator deletion codes.

Decapod crustacean escape responses are adaptive behaviors whose neural bases are well understood. The escape circuit is composed of giant neurons. Lateral giant interneurons (LGs) respond to posterior stimuli by generating a somersaulting tailflip; medial giant interneurons (MGs) respond to anterior stimuli with a backwards tailflip. Both sets of interneurons connect to giant fast flexor motor...

We study the optimal structure for group broadcast problem where the key tree model is extensively used. The objective is usually to find an optimal key tree to minimize the cost based on certain assumptions. Under the assumption that n members arrive in the initial setup period and only member deletions are allowed after that period, previous works show that when only considering the deletion ...

familial adenomatous polyposis (fap) is responsible for < 1% of colorectal cancer (crc) cases and is inherited as an autosomal dominant trait. patients generally present hundreds to thousands of adenomas and develop colorectal cancer by age 35- 40 if left untreated. here we report four patients with germline frameshift mutation (small deletion) at exon 15 of adenomatous polyposis coli (apc) tum...

Proper and timely segregation of the cellular genome is a prime requirement all cell division programs. Mis-segregation chromosomes resulting aneuploidy lead to several clinical consequences. Over years, shugoshin has emerged as key protein factor involved in genetic material dividing cells. Deletion or an altered level reported human malignancies; result, now emerging important tumor-associate...

Data-intensive applications have fueled the evolution of log-structured merge (LSM) based key-value engines that employ out-of-place paradigm to support high ingestion rates with low read/write interference. These benefits, however, come at cost treating deletes as second-class citizens . A delete operation inserts a tombstone invalidates older instances deleted key. State-of-the-art LSM-engine...
