Abstract: A folding exercise rack system for providing an exercise rack that may be easily and compactly stored when not in use. The folding exercise rack generally includes a plurality of extension members pivotably connected to wall-connected mounting brackets. Upright support members connected to the extension members support a barbell and exercise bar. The exercise rack is pivotable from an extended exercise position into a plurality of selectable compact storage positions substantially parallel with and closely adjacent to the wall. The mounting brackets include a plurality of selectable connection points to determine how much space is present between the wall and exercise rack in the storage positions. One connection point allows a retractable exercise bench to be stored in the space between the wall and exercise rack. Mechanisms are provided for locking the exercise rack in a plurality of selected positions.

Abstract: Organometallic radiation resist compositions are described based on tin ions with alkyl ligands. Some of the compositions have branched alkyl ligands to provide for improved patterning contrast while maintaining a high degree of solution stability. Blends of compounds with distinct alkyl ligands can provide further improvement in the patterning. High resolution patterning with a half-pitch of no more than 25 nm can be achieved with a line width roughness of no more than about 4.5 nm. Synthesis techniques have been developed that allow for the formation of alkyl tin oxide hydroxide compositions with very low metal contamination.

Abstract: Precursor solutions for radiation patternable coatings are formed with an organic solvent and monoalkyl tin trialkoxides in which the water content of the solvent is adjusted to be within 10 percent of a selected value. Generally, the water content of the solvent is adjusted through water addition, although water removal can also be used. In some embodiments, the adjusted water content of the solvent can be from about 250 ppm by weight to about 10,000 ppm by weight. With the appropriate selection of ligands, the adjusted precursor solutions can be stable for at least about 42 days, and in some cases at least 8 months.

Abstract: The present invention provides a method for determining cellular response to stimuli. The cells to be tested, for example, may be contained in a section of taste-bud containing lingual epithelium.
