The binding constants of acetate and benzoate to a Pheha-based 15-metallacrown-5 have been determined by a fluorimetric indicator displacement assay demonstrating on a thermodynamic basis the stabilization effect arising from complexation of the less polar carboxylate into the hydrophobic pocket of the metallacrown scaffold.

A simple pyridinium-based tripodal chemosensor, 1, effectively recognizes AMP over ATP and ADP through indicator displacement assay (IDA) technique in water at pH 6.4. The good recognition of 1 is due to the better accommodation of AMP at the core of 1 as well as functional interaction involving hydrogen bonding and charge-charge interaction. The sensor 1 also recognizes intracellular AMP.

background: radial movement of the arterial wall is a well-known indicator of the mechanical properties of arteries in arterial disease examinations. in the present study, two different motion estimation methods, based on the block-matching and maximum-gradient algorithms, were examined to extract the radial displacement of the carotid artery wall. methods: each program was separately implement...

Three indicator displacement assays are described for the detection of phosphatidylserine in a bilayer membrane. A series of Zn-dipicolylamine coordination compounds are used to bind selectively to the phosphatidylserine and act as a colorimetric chemosensing ensemble when combined with the UV-Vis indictor pyrocatechol violet. A similar displacement assay uses a coumarin methylsulfonate derivat...

A new indicator called Vehicle Load Difference Curvature Indicator (VLDCI) was proposed in this paper to further study the application of difference curvature to early warning of simply supported beams. Values of VLDCI can be obtained based on the measured vertical displacement data under a novel vehicle load mode (working condition of concentrated load), which can be obtained by apply vehicle ...

in this paper, a new algorithm for studying elastic wave propagation in the phononic crystals is presented. at first, the displacement-based forms of elastic wave equations are derived and then the forms are discretized using finite difference method. so the new algorithm is called the displacement-based finite difference time domain (dbfdtd). three numerical examples are computed with this met...
