The present invention is a semiconductor apparatus for white light generation and amplification, where, under different current bias, white light can be generated steadily and evenly by folding up multi-wavelength quantum wells and by side-injecting a current. L-arabinose transporters are also introduced into the yeast to enhance the uptake of arabinose. The voltage of the node is boosted up in accordance with stored data by capacitive coupling through a storage capacitor and the potential is read with an amplifier circuit to distinguish data. The external system analyzes the additional IEGM data to confirm the detection of cardiac ischemia using a more sophisticated analysis procedure exploiting additional detection parameters. The gesture sensor also includes one or more light inhibitors positioned relatively nearer the sensing side of the sensing element than the non-sensing side. In one such embodiment, data sets containing sensitive data elements are analyzed using aliases representing sensitive data elements.
