This paper describes hardware that has been built to compress video in real time using full-search vector quantization (VQ). This architecture implements a diierential-vector-quantization (DVQ) algorithm and features a special-purpose digital associa-tive memory, the VAMPIRE chip, which has been fabricated in 2m CMOS. We describe the DVQ algorithm, its adaptations for sampled NTSC composite-col...

The defective Suppressor-mutator (dSpm)-induced allele bronze1-mutable 13 (bz1-m13) and many of its derivative alleles are leaky mutants with measurable levels of flavonol O3-glucosyltransferase activity. This activity results from splicing at acceptor site-1, one of two cryptic 3' splice sites within the dSpm insertion in bz1-m13. In this study, splicing in bz1-m13 change-in-state (CS) alleles...

During the infection cycle of the filamentous bacteriophage M13 a phage specific RNA species is made which selectively directs in vitro the synthesis of the precursor of the major capsid protein encoded by gene VIII. This RNA is unstable (its mean half-life is 11 min) and is made in amounts representing at least 2% of the newly synthesized RN. Nucleotide sequence analysis have indicated that th...

an SH3 domain, followed by a tandem arrangement of Background: Cloned-out of library-2 (Cool-2)/PAK-interDbl homology (DH) and Pleckstrin homology (PH) doactive exchange factor ( -Pix) was identified through mains [6]. This arrangement of DH and PH domains is its ability to bind the Cdc42/Rac target p21-activated characteristic of the Dbl family of guanine nucleotide kinase (PAK) and has been i...

DNA primase has been partially purified from wheat germ. This enzyme, like DNA primases characterized from many procaryotic and eucaryotic sources, catalyses the synthesis of primers involved in DNA replication. However, the wheat enzyme differs from animal DNA primase in that it is found partially associated with a DNA polymerase which differs greatly from DNA polymerase alpha. Moreover, the o...

An M13 phage deletion mutant, M13 delta E101, developed as a vector for selecting DNA sequences that direct DNA strand initiation on a single-stranded template, has been used for cloning restriction enzyme digests of phi X174 replicative-form DNA. Initiation determinants, detected on the basis of clear-plaque formation by the chimeric phage, were found only in restriction fragments containing t...

The fungus Mycosphaerella fijiensis is the causative agent of black sigatoka, which is one of the most destructive diseases of banana plants. Infection with this pathogen results in underdeveloped fruit, with no commercial value. We analyzed the distribution of the M. fijiensis mating-type system and its genetic variability using M13 phage DNA markers. We found a 1:1 distribution of mating...

A theoretical framework for predicting low frequency Raman vibrational spectra of viral capsids is presented and applied to the M13 bacteriophage. The method uses a continuum elastic theory for the vibrational modes and a bond-charge polarizability model of an amorphous material to roughly predict the Raman intensities. Comparison is made to experimental results for the M13 bacteriophage virus.
