Structures of the open-chain tetrapyrrole (bilin) prosthetic groups of the cryptophycean biliproteins phycocyanin 645 (Cr-PC 645; from strain UW374), phycoerythrin 566 (Cr-PE 566; from strain Bermani) and phycoerythrin 545 (Cr-PE 545; from Proteomonas sulcata Hill & Wetherbee) were examined by absorption, 1H NMR spectroscopy, and mass spectrometry. These biliproteins carry the following covalen...

We present improved algorithms for testing monotonicity of functions. Namely, given the ability to query an unknown function f : Σ 7→ Ξ, where Σ and Ξ are finite ordered sets, the test always accepts a monotone f , and rejects f with high probability if it is -far from being monotone (i.e., every monotone function differs from f on more than an fraction of the domain). For any > 0, the query an...

Abstract Candida rugosa lipase (CRL) is an enzyme that widely used in biopharmaceutical and biopesticide industries due to its high catalytic ability reusability. However, conditions from industrial processes are often outside CRL stability range may cause denaturation or destabilization of the enzyme, causing it be not reusable, hence lowering economic value. To increase activity, stability, r...

Sentence (1) strongly suggests that the speaker does not have a sister: (1) John believes that I have a sister. a. Alternative: John knows that I have a sister. b.
