A new approach of reliable image and video transmission over noisy channel is proposed. The proposed subband modulation scheme combines source coding and channel modulation scheme t o achieve high compression ef ic iency and preferable quality. Further performance gain is obtained by multiresolution modulat ion and bits re-mapping scheme that assign e f i c i en t mapping f rom source codeword ...

We examined whether insulin and catecholamines share common pathways for their stimulating effects on glucose uptake. We perfused isolated working rat hearts with Krebs-Henseleit buffer containing [2-3H]glucose (5 mmol/L, 0.05 microCi/mL) and sodium oleate (0.4 mmol/L). In the absence or presence of the phosphatidylinositol 3-kinase (PI3-K) inhibitor wortmannin (3 micromol/L), we added insulin ...

The E/C alpha- and beta-subunits of intra-I-region recombinants were analyzed for primary structural variation by comparative tryptic peptide mapping. The E/C alpha-polypeptides from B10.A, B10.A (3R) and B10.A (5R) showed complete coincident elution of peptides; the E/C beta-chains from B10.A and 3R (or 5R) were approximately 40% different. This suggests that the structural gene for the E/C be...

In contrast to typical membrane proteins that span the lipid bilayer via transmembrane alpha-helices, bacterial outer membrane proteins adopt a beta-barrel architecture composed of antiparallel transmembrane beta-strands. The topology of outer membrane proteins is difficult to predict accurately using computer algorithms, and topology mapping protocols commonly used for alpha-helical membrane p...

Let X,Y be Banach modules over a C∗-algebra and let r1, . . . , rn ∈ R be given. We prove the generalized Hyers-Ulam stability of the following functional equation in Banach modules over a unital C∗-algebra: ∑n j 1 f −rjxj ∑ 1≤i≤n,i / j rixi 2 ∑n i 1 rif xi nf ∑n i 1 rixi . We show that if ∑n i 1 ri / 0, ri, rj / 0 for some 1 ≤ i < j ≤ n and a mapping f : X → Y satisfies the functional equation...

The gene for beta-amylase was isolated from Bacillus polymyxa by molecular cloning in B. subtilis. B. subtilis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotrio...

The gene for beta-amylase was isolated from BacUlus polymyxa by molecular cloning in B. subtils. B. subtlis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotriose ...

The problem considered in the paper can be described as follows. We are given a continuous mapping from one metric space into another which is regular (in the sense of metric regularity or, equivalently, controllability at a linear rate) near a certain point. How small may be an additive perturbation of the mapping which destroys regularity? The paper contains a new proof of a recent theorem of...

Recently the generalizedHyers-Ulam orHyers-Ulam-Rassias stability of the following functional equation ∑m j 1 f −rjxj ∑ 1≤i≤m,i / j rixi 2 ∑m i 1 rif xi mf ∑m i 1 rixi where r1, . . . , rm ∈ R, proved in Banach modules over a unital C∗-algebra. It was shown that if ∑m i 1 ri / 0, ri, rj / 0 for some 1 ≤ i < j ≤ m and a mapping f : X → Y satisfies the above mentioned functional equation then the...
