Abstract: The invention relates to a process aid for use in rigid thermoplastic compositions, and especially in rigid polyvinylchloride (PVC) compositions. The process aid is an acrylic terpolymer of methylmethacrylate, butyl acrylate and styrene at an optimal ratio to produce a significant reduction in melt process viscosity. The resulting reduction in extrusion melt torques enables manufacturers of rigid PVC products to have higher throughput production rates.

Abstract: First data to be sent by a first party to a second party is encrypted using an encryption key string formed using at least a hash value generated using second data and a secret, shared with a trusted party, that serves as identification of the first party. The second data comprises, for example, one or more conditions that serve as identifiers of the second party, and a hash-value element generated by hashing the first data. The encrypted first data and the encryption key string is made available to the second party which forwards the encryption key string to the trusted party with a request for the corresponding decryption key. The trusted party carries out at least one check on the basis of data contained in the encryption key string and, if this at least one check is satisfactory, provides a decryption key to the second party.

Abstract: Method and system for generating electromyographic or sub-audible signals (“SAWPs”) and for transmitting and recognizing the SAWPs that represent the original words and/or phrases. The SAWPs may be generated in an environment that interferes excessively with normal speech or that requires stealth communications, and may be transmitted using encoded, enciphered or otherwise transformed signals that are less subject to signal distortion or degradation in the ambient environment.

Abstract: Modeling and simulation of free and forced structural vibrations is essential to an overall structural health monitoring capability. In the various embodiments, a first principles finite-difference approach is adopted in modeling a structural subsystem such as a mechanical gear by solving elastodynamic equations in generalized curvilinear coordinates. Such a capability to generate a dynamic structural response is widely applicable in a variety of structural health monitoring systems. This capability (1) will lead to an understanding of the dynamic behavior of a structural system and hence its improved design, (2) will generate a sufficiently large space of normal and damage solutions that can be used by machine learning algorithms to detect anomalous system behavior and achieve a system design optimization and (3) will lead to an optimal sensor placement strategy, based on the identification of local stress maxima all over the domain.

Abstract: Using resonant interactions to directly and tomographically image neural activity in the human brain using magnetic resonance imaging (MRI) techniques at ultra-low field (ULF), the present inventors have established an approach that is sensitive to magnetic field distributions local to the spin population in cortex at the Larmor frequency of the measurement field. Because the Larmor frequency can be readily manipulated (through varying Bm), one can also envision using ULF-DNI to image the frequency distribution of the local fields in cortex. Such information, taken together with simultaneous acquisition of MEG and ULF-NMR signals, enables non-invasive exploration of the correlation between local fields induced by neural activity in cortex and more ‘distant’ measures of brain activity such as MEG and EEG.
