2014 A Ginzburg-Landau Hamiltonian describing systems of disc-like molecules in the columnar phase is used to investigate the properties of the columnar-crystalline transition. Near the transition temperature in the columnar phase, the enhancement of the bend elastic constant is found by a perturbation calculation. The gauge coupling mechanism which leads to a first order transition in the case...

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...

A new four elements compact antenna array is presented and discussed to achieve enhanced phase resolution without sacrificing the array output power. This structure inspired by the Ormia Ochracea’s coupled ears. The analogy between this insect acute directional hearing capabilities and the electrically compact antenna array is used to enhance the array sensitivity to direction of arrival estima...
