    Abstract: One aspect of the present invention is directed to a composition. The composition includes a dispersion inducer comprising: H3C—(CH2)n—CHmCHmR, where is a single or double carbon-carbon bond, m is 1 or 2, n is 2 to 15, and R is a carboxylic acid, a salt, an ester, or an amide, where the ester or amide is an isostere or biostere of the carboxylic acid. The composition additionally contains an additive component selected from one or more of the group consisting of biocides, surfactants, antibiotics, antiseptics, detergents, chelating agents, virulence factor inhibitors, gels, polymers, pastes, edible products, and chewable products. The composition is formulated so that when it is contacted with a biofilm produced by a microorganism, where the biofilm comprises a matrix and microorganism on a surface, the dispersion inducer selectively acts on the microorganism and has a suitable biological response without a required direct effect on the matrix to disperse the biofilm. The present invention is also directed to methods of using this compound.

    Abstract: A processing unit and a method of operating a processing unit. In an embodiment, the processing unit comprises a SIMON block cipher for transforming plaintext data into encrypted data. A key expansion module generates and outputs one or more encryption keys; and the key expansion module includes a first series of adiabatic registers for holding key generation data values, and for using adiabatic switching to transmit the key generation data values through the first series of adiabatic registers. A round function module receives the plaintext data and the one or more encryption keys, encrypts the plaintext data to generate the encrypted data, and outputs the encrypted data; and the round function module includes a second series of adiabatic registers for holding encryption data, and for using adiabatic switching to transmit the encryption data through the second series of adiabatic registers.
