We consider the concatenation of a convolutional code (CC) with an optimized cyclic redundancy check (CRC) as promising paradigm for good short blocklength codes. The resulting CRC-aided naturally permits use serial list Viterbi decoding (SLVD) to achieve maximum-likelihood decoding. encoder interest is rate-$1/\omega$ and either zero-terminated (ZT) or tail-biting (TB). called CRC-ZTCC CRC-TBC...

The gene (crc) responsible for catabolite repression control in Pseudomonas aeruginosa has been cloned and sequenced. Flanking the crc gene are genes encoding orotate phosphoribosyl transferase (pyrE) and RNase PH (rph). New crc mutants were constructed by disruption of the wild-type crc gene. The crc gene encodes an open reading frame of 259 amino acids with homology to the apurinic/apyrimidin...

This paper examines the relationship between organizational culture and Information Systems (IS) adoption. Three major perspectives integration, differentiation and fragmentation for understanding the effect(s) of culture on IS adoption in organizations are reviewed. Using Cultural Theory to critique these three perspectives, it is argued that each perspective in isolation offers a restricted v...

In the extant vertical integration literature, the question of how the firm’s portfolio of outsourced work is managed across suppliers has been relatively understudied. We seek to advance this area of research by examining factors that influence how concentrated the firm’s outsourcing is among its set of suppliers. Using data on the outsourcing of patent legal services, we find empirical eviden...

The majority of colorectal cancers (CRCs) arise from adenomatous polyps. In this study, we sought to present the underrecognized CRC with the residual polyp of origin (CRC RPO+) as an entity to be utilized as a model to study colorectal carcinogenesis. We identified all subjects with biopsy-proven CRC RPO+ that were evaluated over 10 years at Mayo Clinic, Rochester, MN, and compared their clini...

The frequency of synchronous or metachronous multiple primary carcinomas in patients with gastrointestinal carcinoma or colorectal carcinoma (CRC) has been reported to be approximately 10%. We determined the role of hMSH2 and hMLH1 in double carcinomas with both GC and CRC. Fifty-six patients with synchronous or metachronous colorectal carcinoma with gastric carcinoma (CRC with GC), and 69 pati...

Colorectal cancer (CRC) is the second most common cancer in Western countries. Hereditary forms only correspond to 5% of CRC burden. Recently, genome-wide association studies have identified common low-penetrant CRC genetic susceptibility loci. Early-onset CRC (CRC<50 years old) is especially suggestive of hereditary predisposition although 85-90% of heritability still remains unidentified. CRC...

A mathematically correct form of the linear storage element’s routing equation is specified requiring only a slight modification of the existing HEC-HMS routine. The new formulation, unlike the current version in use, is unconditionally stable as long as the time step and the storage coefficient values are trivially specified as positive numbers.
