Abstract: Devices for use in cold-field emission and methods of forming the device are generally presented. In one example, a method may include providing a conductive base, dispersing carbon-filled acrylic onto the conductive base to form a conductive film, coupling a copper plate to a first side of the conductive film, and irradiating the conductive film. The method may further include dispersing carbon nanotubes (CNTs) on a second side of the conductive film to form a substantially uniform layer of CNTs, removing excess CNTs from the second side, and curing the conductive film. In one example, a device may include a polycarbonate base, a layer of carbon-filled acrylic on one side of the polycarbonate base and a layer of irradiated carbon-filled acrylic on the other, a copper plate coupled to the carbon-filled acrylic, and a substantially uniform layer of randomly aligned CNTs dispersed on the irradiated carbon-filled acrylic.

Abstract: A low noise amplifier (LNA) system with controllable linearity and noise figure versus power consumption is provided. The system comprises two control inputs for tuning. One input controls an effective transistor width, and the other input controls bias current. Changes to the effective transistor width alter a gain that is applied to a signal, and changes to the bias current alter a power consumption of the system. For more stringent signal specifications, an impedance matched inductive degeneration variation of the LNA is provided.

Abstract: A device and method for precoding vectors in a communication system is provided. A transmitter may precode a data vector using information regarding a communication channel prior to transmitting the data vector. The transmitter may precode the data vector in a manner that reduces an energy value of a resulting transmit data vector so as to minimize interference in a received signal at a receiver. The transmitter may perturb entries of the data vector one-by-one in an iterative fashion until a minimum in an energy value of the transmit data vector is obtained.

Abstract: Techniques disclosed herein are generally related to methods and devices for determining spectral samples for a finite length sequence. Some example methods include, for each time-indexed sample in a data sample sequence comprising a plurality of samples, generating a sample-specific phase value set associated with a respective time index of the sample and a set of predetermined frequencies. Some examples further include, mapping each sample-specific phase value set to a corresponding sample-specific iso-phasor set and calculating an altered iso-phasor set. Some examples include generating a rotated sample value set by unmapping the altered iso-phasor set to obtain real and imaginary components of the sample rotated by the corresponding sample-specific phase value set. Some addition examples include summing selected rotated sample values from each of the sets of rotated sample values to create a spectral sample vector having a spectral sample of the sequence and outputting the spectral sample vector.

Abstract: Using annotated structural descriptions and binding data for two, four or more input ligand molecules known to bind to a given protein target, a profile of the ligand molecules can be created by identifying patches of ligand molecules which have similar chemical and/or stereochemical descriptions, scored with the use of a weight dataset (e.g., substitution matrix). A database containing annotated molecular descriptions can be searched according to the profile to identify, for example, additional ligands that can bind to the protein target. Information such as the input ligands, the additional ligands, and literature related to these molecules, and modeling tools can be displayed in a user interface.

Abstract: A one-dimensional structural description of a ligand molecule can be annotated to include, for one or more atoms, information from a force field database. The information can be provided by an Assisted Model Building and Energy Refinement parameter list or a similar source. The annotation can be carried out using one or more intermediate structural description formats and can include identifying one or more fragment types that make up the ligand molecule.
