Abstract: A diffractive multifocal lens is disclosed, comprising an optical element having at least one diffractive surface, the surface profile comprising a plurality of annular concentric zones. The optical thickness of the surface profile changes monotonically with radius within each zone, while a distinct step in optical thickness at the junction between adjacent zones defines a step height. The step heights for respective zones may differ from one zone to another periodically so as to tailor diffraction order efficiencies of the optical element, in one example of a trifocal lens, step heights alternate between two values, the even-numbered step heights being lower than the odd-numbered step heights.

Abstract: Methods of vulcanization using a high content sulfur polymer, instead of elemental sulfur, have been developed. These high sulfur content polymers are referred to as Chalcogenide Hybrid Inorganic/Organic Polymers (CHIP) materials and have good polymer compatibility in that they are soluble in a number of polymers. Furthermore, CHIP materials may have weaker bonds than the S—S bonds of elemental sulfur and thus provide for a higher crosslinking efficiency vulcanization.

Abstract: Methods for identifying animals that are genetically superior, drugs, nutritional strategies, or physiological manipulations that improve feed efficiency or productivity of animals, e.g., selecting animals that are genetically superior for feed efficiency or productivity based on metabolic rates of particular tissues, wherein metabolic rates of certain tissues such as skeletal muscle are inversely proportional to feed efficiency, while metabolic rates of other tissues such as mammary gland are directly proportional to milk production. Thus, animals with low skeletal muscle metabolic rates are generally more feed efficient, e.g., gain more weight per unit of food. The methods herein may be used to improve the genetics, nutrition, and handling or animals more efficiently produced animal products, e.g., meat production, milk, production, egg production, wool production, etc. The methods herein may also be used to determine estimated breeding values of animals for feed efficiency, growth, or production.

Abstract: Various examples are provided related to determination of contact angle of sessile drops. In one example, a method includes determining a volume of a sessile drop of fluid disposed on a test surface; determining a height of the sessile drop of fluid; and determining a contact angle of the sessile drop of fluid based upon the volume and the height of the sessile drop. In another example, a system includes a volume sensing, a height sensing, and computing that can determine a volume and height of a sessile drop using volume and height data from the sensing, and determine a contact angle of the sessile drop with the volume and the height. The contact angle and surface tension can be determined with at least three of volume, a height, a footprint radius, a radius of maximum horizontal extent, and/or an apex radius of curvature of the drop.

Abstract: Disclosed are methods and systems for detecting RNA and sequencing RNA in a wide range of samples such as samples with low concentrations of nucleic acid, samples with degraded nucleic acid, samples that would not otherwise be amenable to conventional sequencing or RNA detection methods, poor quality samples, high quality samples in which rare mutations are sought, formalin-fixed paraffin-embedded samples, blood samples, etc. The methods of the present invention may use paired, large panels of primers to amplify many short fragments that overlap between but not within each panel. Each panel's amplicon set may fill the gaps between those of the opposing panel, thereby providing complete gene or genomic coverage. A preliminary, multiplex amplification step amplifies target nucleic acid for all downstream reactions such as Sanger sequencing, cloning, and Next Generation Sequencing (NGS).

Abstract: Metallopolymers composed of polymers and catalytically active diiron-disulfide ([2Fe-2S]) complexes are described herein. [FeFe]-hydrogenase mimics have been synthesized and used to initiate polymerization of various monomers to generate metallopolymers containing active [2Fe-2S] sites which serve as catalysts for a hydrogen evolution reaction (HER). Vinylic monomers with polar groups provided water solubility relevant for large scale hydrogen production, leveraging the supramolecular architecture to improve catalysis. Metallopolymeric electrocatalysts displayed high turnover frequency and low overpotential in aqueous media as well as aerobic stability. Metallopolymeric photocatalysts incorporated P3HT ligands to serve as a photosensitizer to promote photoinduced electron transfer to the active complex.

Abstract: A method for measuring distorted illumination patterns and correcting image artifacts in structured illumination microscopy. The method includes the steps of generating an illumination pattern by interfering multiple beams, modulating a scanning speed or an intensity of a scanning laser, or projecting a mask onto an object; taking multiple exposures of the object with the illumination pattern shifting in phase; and applying Fourier transform to the multiple exposures to produce multiple raw images. Thereafter, the multiple raw images are used to form and then solve a linear equation set to obtain multiple portions of a Fourier space image of the object. A circular 2-D low pass filter and a Fourier Transform are then applied to the portions. A pattern distortion phase map is calculated and then corrected by making a coefficient matrix of the linear equation set varying in phase, which is solved in the spatial domain.

The pellet dispenser may be contained within the cage or otherwise attached to the cage so as not to take up additional floor space in the cage which should be allocated for the small laboratory animal. The pellets may be gravity or screw drive fed towards an ejector port. At prescribed times during the day, a prescribed number of pellets may be ejected into the animal cage. Additional components of the pellet dispenser include an ejector (e.g., a linear actuator) and pellet hopper.
