We shall show that if the restricted isometry constant (RIC) δs+1(A) of the measurement matrix A satisfies δs+1(A) < 1 √ s+ 1 , then the greedy algorithm Orthogonal Matching Pursuit(OMP) will succeed. That is, OMP can recover every s-sparse signal x in s iterations from b = Ax. Moreover, we shall show the upper bound of RIC is sharp in the following sense. For any given s ∈ N, we shall construc...

Outer membrane proteins (OMP) are generally porins, functioning as molecular sieves assisting in the transmembrane transportation. Heat modifiable characteristics of OMP from P. multocida B: 2 have been explored to know their basic characteristics on event of temperature rise. A major band of 32 kDa and two minor bands of approximately 39 and approximately 28 kDa were found to be heat modifiabl...

A serotyping system for nontypable Haemophilus influenzae (NTHI) was developed by using isolated outer membrane protein (OMP) preparations and rabbit antisera. OMPs of 23 strains were isolated by molecular sieve chromatography of outer membranes in 1.5% sodium deoxycholate buffer. These OMP preparations were relatively free of lipopolysaccharide as determined by silver staining of sodium dodecy...

Lansoprazole (LNS) and omeprazole (OMP) are therapeutically important drugs, and the need arose for a simple, reliable method for their content uniformity of their tablets. The anodic polarographic behavior of lansoprazole and omeprazole has been studied in Britton-Robinson buffer (BRb) over the pH range 4.1-11.5. In BRb of pH 7 well-defined anodic waves were produced with diffusion-current con...

The feasibility of sparse signal reconstruction depends heavily on the inter-atom interference of redundant dictionary. In this paper, a semi-blindly weighted minimum variance distortionless response (SBWMVDR) is proposed to mitigate the inter-atom interference. Examples of direction of arrival estimation are presented to show that the orthogonal match pursuit (OMP) based on SBWMVDR performs be...

Active immunization of guinea pigs and rabbits with outer membrane proteins (OMP) isolated from Shigella flexneri 3a and Shigella sonnei phase I protected the animals against keratoconjunctivitis shigellosa induced with the homologous or heterologous strain. Protection was also achieved in rabbits after passive immunization with anti-OMP immune serum. Active immunization with lipopolysaccharide...

In compressive sensing, the fundamental problem is to reconstruct sparse signal from its nonadaptive insufficient linear measurement. Besides sparse signal reconstruction algorithms, measurement matrix or measurement dictionary plays an important part in sparse signal recovery. Orthogonal Matching Pursuit (OMP) algorithm, which is widely used in compressive sensing, is especially affected by me...

The transportation of membrane proteins through the aqueous subcellular space is an important and challenging process. Its molecular mechanism and the associated structural change are poorly understood. Periplasmic chaperones, such as Skp in Escherichia coli, play key roles in the transportation and protection of outer membrane proteins (OMPs) in Gram-negative bacteria. The molecular mechanism ...

ToxR, a transmembrane regulatory protein, has been shown to respond to environmental stimuli. To better understand how the aquatic bacterium Vibrio anguillarum, a fish pathogen, responds to environmental signals that may be necessary for survival in the aquatic and fish environment, toxR and toxS from V. anguillarum serotype O1 were cloned. The deduced protein sequences were 59 and 67% identica...

Moraxella catarrhalis is a common commensal of the human respiratory tract that has been associated with a number of disease states, including acute otitis media in children and exacerbations of chronic obstructive pulmonary disease in adults. During studies to investigate the outer membrane proteins of this bacterium, two novel major proteins, of approximately 19 kDa and 16 kDa (named OMP J1 a...
