摘要:
A novel flooring composition was developed based on a blend comprising: a) an elastomer; b) a random propylene/alpha-olefin copolymer; c) a cross linking agent; and optionally d) a melt strength enhancing polymer. This composition achieves a unique balance of properties, exhibiting often-conflicting performance requirements. These include low gloss and excellent pattern duplication in embossing, low modulus, minimal odor, excellent grain acceptance and abrasion resistance, while remaining thermoformable and maintaining minimal shift in viscosity during recycle.

An alarm pillow and associated method includes a pillow with an opening at a proximal end thereof, a core member, and an outer layer positioned thereabout. A cavity is formed between the core member and the outer layer respectively. The cavity has an open end defined along the proximal opening of the pillow, and a closed distal end seated medially of the proximal end and a distal end of the pillow respectively. A portable electronic alarm device is removably positioned within the cavity. The device has a planar top surface with a user interface, and a planar bottom surface extending parallel to the top surface. The device is slidably positional through the proximal opening of the cavity and abuts against the distal end of the cavity.

A method and software implementation for spatial pattern analysis. A user-guided test procedure is implemented to measure features of an antenna under test to determine the antenna's far-field patterns. The antenna features include RF amplitude or phase, and position and orientation relative to a receiving object.

摘要:
The molecules and methods of the present invention provide a means for in vivo production of a trans-spliced molecule in a selected subset of cells. The pre-trans-splicing molecules of the invention are substrates for a trans-splicing reaction between the pre-trans-splicing molecules and a pre-mRNA that is uniquely expressed in the specific target cells. The in vivo trans-splicing reaction provides a novel mRNA that is functional as mRNA or encodes a protein to be expressed in the target cells. The expression product of the mRNA is a protein of therapeutic value to the cell or host organism, a toxin that kills the specific cells or a novel protein not normally present in such cells. The invention further provides PTMs that have been genetically engineered for the identification of exon/intron boundaries of pre-mRNA molecules using an exon tagging method.
