Summary Microarray platforms, enabling simultaneous measurement of many allergens with a small serum sample, are potentially powerful tools in allergy diagnostics. We report here the first study comparing a fully automated microarray system, the Micr

A two-dimensional, square-lattice photonic crystal model possessing analytical solutions is investigated to ascertain the requirements for negative refraction to occur. The refraction properties are presented for both polarizations assuming in-plane

The influence of an asymmetric periodic grooved cell surface on the 2D static director configuration of a nematic liquid crystal has been investigated. The minimum in the Frank-Oseen free energy was solved numerically with the Rapini-Papoular form of

Static nematic liquid crystal director configurations have been calculated numerically for alignment over an asymmetric grooved surface profile. The results demonstrate the existence of a low pretilt regime, where the director field follows the conto

A new class of superconductivity-enhanced, quasi-particle interference effects (SEQUINs) is suggested, based on interference from the order parameter phase gradient of a single superconductor (S) in contact with a normal metallic lead (N) of finite w

We examine equivalent forms of the current-voltage relationship applicable to mesoscopic superconductors and use one of these to derive general conditions for the sign of the conductance in a four-probe measurement. For disordered systems, with well

We compute sample-to-sample fluctuations in the electrical conductance G(NS) of mesoscopic normal-superconducting boundaries. If the superconductor is clean and the normal conductor diffusive, the rms deviation deltaG(NS) is approximately a factor of

We examine the change deltaG in the two-probe electrical conductance G of a mesoscopic sample due to the switching on of superconductivity and prove that when conductance of the normal mesoscopic host is sufficiently high, the onset of superconductiv

We examine sample-to-sample fluctuations in the electrical conductance G of a mesoscopic structure containing superconducting islands and demonstrate that these are consistent with predictions of universal conductance fluctuations in normal disordere

After presenting an intuitive picture of quasi-particle transport in mesoscopic superconductors, which emphasizes the intimate relation between Andreev scattering and zero resistivity, the authors develop a general theory of DC transport in mesoscopi
