Abstract: Crystalline forms of a GABAA ?5 agonist, pharmaceutical compositions and combinations comprising those crystalline forms, their use in methods of treating cognitive impairment associated with central nervous system (CNS) disorders, cognitive impairment associated with brain cancer, the brain cancer itself or Parkinson's disease psychosis and methods of producing the crystalline forms.

Abstract: The invention includes processes for the synthesis of amphetamine, dexamphetamine, methamphetamine, derivatives of these, including their salts, and novel precursors and intermediates obtained thereby, by synthesizing aziridine phosphoramidate compounds in specified solvents at specified temperatures, and then converting to a novel aryl or aryl-alkyl phosphoramidate precursors using an organometallic compound such as a copper salt, where the novel aryl or aryl-alkyl phosphoramidate precursor is then easily converted to the target compounds using known reactions.

Abstract: A bi-layer photovoltaic cell, and method (100) of making same, with an electric field applied at the p-n heterojunction interface. The cell includes a first semiconductor layer including a binder, nanocrystals of an n-type semiconductor, and spatially bound cations and a second semiconductor layer contacting the first semiconductor layer that includes a binder, nanocrystals of a p-type semiconductor, and spatially bound anions. The cell further includes a p-n heterojunction at the contacting interface between the first and second semiconductor layers. An electric field is created by the spatially bound cations and anions that are located in the layers proximal to the p-n heterojunction. The nanocrystals are single crystals of organic semiconductors that are less than 50 nanometers in size and that comprise a majority of the volume of their respective layers. The binder is a polymer matrix, such as an epoxy. The cell includes electrical contacts abutting the semiconductor layers.

Abstract: A modular heat sink decoupling capacitor array includes a plurality of modules, each defining parallel distributed decoupling plates, and each module forming a heat sink fin. Each module includes multiple spaced apart contacts for providing low inductance connections with an associated device. A power distribution interposer module is attached to a heat sink surface of the modular decoupling capacitor. The interposer module is used for implementing power delivery without using valuable ball grid array (BGA) connections and printed circuit board (PCB) layers.

Abstract: A method and apparatus are provided for implementing very high density signal probing of a printed circuit board having a pad pattern connected to signals of interest. A metal plate includes a plurality of through holes arranged in a predefined pattern that corresponds to the pad pattern on the printed circuit board. At least one signal module is inserted within a selected one of the through holes of the metal plate. Each signal module defines a coaxial connector for electrical mating engagement with a coaxial cable connector and has an embedded resistor. At least one power/ground module is inserted within a selected one of the through holes. Each power/ground module contains a high dielectric constant material between an outer conductor and a center conductor defining a capacitor. The capacitor provides a low impedance path between the metal plate and a power or ground pad of the printed circuit board.
