A connector for coupling panels which does not influence upon an electrically connected part of a connector to be attached to a panel even if an external force is applied to the panel. It consists in using at least one multifunctional monomer comprising at least three reactive functions and at least another multifunctional monomer, in amounts such that the terminal group concentrations are balanced. Also provided are pharmaceutical compositions and kits including such peptides as well as methods using same for diagnosing and treating amyloid associated diseases. A sorter within the event interpretation system orders the software events relative to one another so as to correspond to an order of the physical events. The compositions, products, methods and systems of the invention may be used for rapid, and continual monitoring of ecosystems for parameters of interest, such as the presence or absence of mercury. Each layer of the first set consists essentially of a different organic semiconductor material having a higher LUMO and a higher HOMO, relative to the material of an adjacent layer of the plurality of organic semiconductor layers closer to the cathode.
