Abstract:
Novel alpha-hydrogen substituted nitroxyl compounds and their corresponding oxidized (oxoammonium cations) and reduced (hydroxylamine) forms, and the use of such compounds, inter alia, for oxidation of primary and secondary alcohols to aldehydes and ketones, respectively; resolution of racemic alcohols; desymmetrization of meso-alcohol; as radicals and spin trapping reagents; and as polymerization agents. Processes for preparing the novel nitroxyl/oxoammonium/hydroxylamine compounds from the corresponding amines, and certain novel amine derivatives and their uses. The compounds and amine precursors are useful as ligands for transition metals and as organocatalysts in e.g., aldol reactions.
Abstract:
A system and method for directional sound sensing directs an optical sensing beam to an object of interest having a rough surface that vibrates acoustically. The light is reflected thereby and scattered as a speckle pattern that includes multiple speckles having a random distribution of phase offsets. A detector array having multiple detector elements receives and detects the speckle pattern and produces signals that are linearly proportional to phase modulation of the speckles. A summer receives signals from at least two of the detector elements that are offset at different phases and sums the received signals to generate a non-vanishing signal representative of an acoustic signal.
Abstract:
Microelectronic network devices and components are fabricated by binding or complexing at least one electronically functional substance to a molecular fiber, such as a nucleic acid fiber. The devices and components can be combined by interconnecting the complexed fibers to provide microelectronic circuits or networks. Assembly processes involve interactions of various combinations of the fibers and substances used in fabrication.

A method for the fabrication of such a material. The conducting material is useful in the fabrication of electronic components, electrodes, sensors, diodes, field effect transistors, and field emission electron sources.
Abstract:
An Optical Access Network, a Optical Network Unit (ONU) and various methods for exchanging information are provided. The method may include: receiving, by the ONU, a pilot signal and down-stream information signals; wherein the pilot signal is received at a pilot frequency slot and the downstream information signals are received at a downstream information frequency slot; wherein the ONU is allocated with a spectral slice that comprises the pilot frequency slot, the downstream information frequency slot, a guard frequency slot and an upstream information frequency slot; wherein at least one other spectral slice is allocated for exchanging information with at least one other group of ONUs; splitting the downstream information signals to downstream information signals portions; splitting the pilot signals to pilot signals portions; detecting downstream information, in response to at least a first portion of downstream information signals; modulating a portion of the pilot signal by upstream information signals to provide upstream information signals that are within the upstream information frequency slot; modulating a second portion of the downstream information signals by the upstream information signals to provide upstream secondary signals that are outside the pilot frequency slot, the downstream information frequency slot and the upstream information frequency slot; and upstream transmitting the upstream information signals and the upstream secondary signals.
Abstract:
A method for photogrammetric texture mapping using casual images is provided. The method may include the following steps: estimating, for each vertex of at least a portion of a three dimensional (3D) mesh representing a model, projection parameters associated with a virtual camera that is unique for each vertex; mapping pixels from a two dimensional (2D) image to the vertices, such that each mapping of a pixel is based on the estimated respective virtual camera parameters; and texturing the portion of the mesh with corresponding mapped pixels wherein vertices on the textured portion are selected such that they are visible from a specified viewpoint associated with the 3D mesh.
