In this paper we provide numerical evidence of the richer behavior of the connectivity degrees in heterogeneous preferential attachment networks in comparison to their homogeneous counterparts. We analyze the degree distribution in the threshold model, a preferential attachment model where the affinity between node states biases the attachment probabilities of links. We show that the degree den...

the efficacy of activation methods and coupling were studied in the context of performance in batch and fixed bed binding experiments utilizing cell culture fluids or blood plasma as feedstock. conclusions were drawn regarding selection of solid phase according to pore size, rigidity, ph stability, chemistry of derivation and activation, and gross concentration of immobilized ligand required fo...

Degree/ connectivity (k) k A =Nb of edges through A=5 B 4 =Fraction of SPs passing through A =0.090 Assortativity/average nearest neighbor's connectivity (NC) Shortest path (SP) between two nodes Betweenness/ centrality (B) Clustering coefficient/ interconnectivity (C) C A = Actual links between A's neighbors (black) Possible links between A's neighbors (orange) A D-Degrees follow Poisson (or p...

in this study we produced and purified a high titer of specific and high affin¬ity fab fragments of anti-digoxin antibody. immunization of rabbits with a conju¬gate of the cardiac glycoside digoxin, coupled by a periodate oxidation method to the amino group of lysine in bovine serum albumin resulted in the production of this type of high titer digoxin-specific antibodies with exceptionally high...

two sialic acid specific lectins episesarma tetragonum agglutinin–1 and 2 were purified from the hemolymph of the mangrove crab, episesarma tetragonum . the major lectin was purified using cnbr-activated sepharose 4b conjugated to fetuin. n-acetyl glucosamine containing buffer was used for elution. the hemagglutination activity of purified lectin was inhibited by glycoproteins containing siaα, ...

The Affinity Laws for fans (and pumps) provide a way of determining new fan or pump speed given fan or pump performance curve data and a desired operating point (combination of flow rate and pressure) that does not fall on the curve. However, the affinity law calculations require using a point on the curve (hereafter referred to as the “basic point”) to determine the new speed. Most references ...

polymorphisms in the β subunit of the high affinity receptor for ige (fcεriβ) and interferon-γ (ifn-γ) genes may influence the risk of asthma. however, the results in asian population are still debatable. we performed a meta-analysis to ascertain the association between the fcεriβ e237g, fcεriβ -109c/t, and ifn-γ 874t/a polymorphisms and asthma in an asian population. databases including pubmed...

background: the affinity of an antibody to its antigen is a crucial parameter in its biological activity and performance of an immunoassay such as elisa. affinity of most igg specific mabs are often determined by methods which require labeling of either antigen or antibody, and are sometimes difficult to control, do not always lead to the expected signal and often result in immunological modifi...
