This paper presents a uniied systematic framework of dynamic controller synthesis for systems described by Takagi-Sugeno (T-S) model. The control laws are in the form of so-called parallel distributed compensation (PDC) introduced by the authors. This paper provides two results. First, we introduce the notion of dynamic PDC compensators and provide a set of suf-cient LMI conditions for the exis...

Hyperbranched polyglycerols (HPGs) are ideal scaffolds for the multivalent presentation of saccharides, due to their biocompatible, carbohydrate-like properties; here, we report the conjugation of galactosesugar moieties to HPG, and the multivalent effect of these constructs on selectin binding.

We obtain subordination and superordination preserving properties for the Saigo type generalized fractional differ-integral operator, defined for multivalent functions in the open unit disk. A differential sandwich-type theorem for these multivalent function, and some consequences are also presented.

Electrostatic properties and stability of charged virus-like nano-shells are examined in ionic solutions with monovalent and multivalent ions. A theoretical model based on a thin charged spherical shell and multivalent ions within the "dressed multivalent ion" approximation, yielding their distribution across the shell and the corresponding electrostatic (osmotic) pressure acting on the shell, ...

Multivalency is the increase in avidity resulting from the simultaneous interaction of multiple ligands with multiple receptors. This phenomenon, seen in antibody-antigen and virus-cell membrane interactions, is useful in designing bioinspired materials for targeted delivery of drugs or imaging agents. While increased avidity offered by multivalent targeting is attractive, it can also promote n...

Cyclodextrin bilayer vesicles have dynamic membranes that recognize guest molecules through efficient multivalent host-guest interaction reminiscent of multivalent binding of a ligand with receptors in a biological membrane.

The multivalent character of dendrimers has positioned these well-defined, highly branched macromolecules at the forefront in the development of new contrast agents for biomedical magnetic resonance imaging (MRI). By modifying the periphery of the dendrimer with gadolinium(III) chelates, the relaxivity of the resulting MRI contrast agent is increased considerably, compared to low molecular weig...

Multivalent ligands can function as inhibitors or effectors of biological processes. Potent inhibitory activity can arise from the high functional affinities of multivalent ligand-receptor interactions. Effector functions, however, are influenced not only by apparent affinities but also by alternate factors, including the ability of a ligand to cluster receptors. Little is known about the molec...

Multivalent-ion (such as Zn2+, Mg2+, Al3+) batteries are considered a prospective alternative for large-scale energy storage. However, the main problem of cathode materials multivalent-ion is sluggish diffusion multivalent ions. Many will self-adjust under electrochemical conditions to achieve optimal state In this review, significant role in situ structural reconstruction suggested. The types,...

Multivalent protein-carbohydrate interactions that are mediated by sugar-binding proteins, i.e., lectins, have been implicated in a myriad of intercellular recognition processes associated with tumor progression such as galectin-mediated cancer cellular migration/metastatic processes. Here, using a modified ELISA, we show that glycodendrimers bearing mixtures of galactosides, lactosides, and N-...
