Abstract: Shape-programmable liquid crystal elastomers. The shape-programmable liquid crystal elastomers being synthesized by filling an alignment cell with liquid crystal monomers. The liquid crystal monomers align to a surface of the alignment cell and then are polymerized with a dithiol chain transfer agent. The alignment cell is configured to impose a director orientation on a portion of the shape-programmable liquid crystal elastomer. For some embodiments, liquid crystal elastomer laminates are prepared by arranging a plurality of liquid crystal elastomers such that a director orientation of each liquid crystal elastomer of the plurality is in registered alignment with an adjacent liquid crystal elastomer of the plurality. The arrangement is secured and the plurality of liquid crystal elastomers cured.

Abstract: Systems and methods of detecting a vortex made by a travelling object is disclosed. In some configurations, a graphic recognition algorithm and vortex similarity engine are used to determine whether a visual media file captured by a media collector contains a vortex. The vortex similarity engine may be configured to determine or identify certain properties about the travelling object based on the travelling object vortex. In some configurations, a computer may trigger an alert if a travelling object vortex is not expected to be in the visual media file.

Abstract: This disclosure concerns electrically conducting poly(pyrazoles). The concept of oligomerizing and polymerizing substituted aminopyrazole derivatives combined with a monomer activation procedure involving base-mediated conversion of the protonated pyrazole ring nitrogen to amine salt was developed. This disclosure concerns the specific chemistries needed for the synthesis of a pyrazole monomer used in the polymer synthesis. The procedure used for blending the novel polypyrazoles with other compounds needed for construction of solar cells for testing was developed. This disclosure concerns the concept of using these types of heteroatom-rich, electron-deficient oligomers or polymers as n-dopable or p-dopable electron acceptors in photovoltaic cells. This disclosure concerns synthesizing the starting monomer compounds and polypyrazoles.

Abstract: Reported herein are novel recombinant respiratory syncytial viruses (RSV) having an attenuated phenotype in which the native positions of the NS1 and/or NS2 genes in the RSV genome are shifted to a higher position, that is at positions that are more distal to the promoter. The changes in the gene positions may be present in combination with mutations at other loci to achieve desired levels of attenuation and immunogenicity. The recombinant RSV strains described here are suitable for use as live-attenuated RSV vaccines. Also provided are polynucleotide sequences capable of encoding the described viruses, as well as methods for producing and using the viruses.

Abstract: Methods, apparatus, and systems are disclosed for implementing a fiber optic reflectance standard (FORS) for testing and/or calibration of a test instrument (TI), which provides a traceable means to calibrate the making optical return loss measurements (ORLM). The apparatus for implementing the FORS may include an optical splitter, first and second optical inputs coupled to the optical splitter, and an optical fiber having first and second ends, and coupled to the optical splitter at the first end of the optical fiber. Furthermore, the apparatus includes an attenuator (e.g., a mechanical attenuator) configured to contain a portion of the optical fiber between the first and second ends and selectively attenuate optical signal gain of the optical fiber. The testing and/or calibration results in an uncertainty that is at least four times better than a typical test instrument.

Abstract: Provided herein are shaped-charges for focusing a filler, such as a fluid mass, and related methods of using the shaped-charges for disruption of an explosive target. The shaped-charge comprises an attenuating body positioned and configured to attenuate rarefaction waves to increase filler, including a fluid mass, explosively driven out of the container toward a target while also maintaining and enhancing fluid jet integrity. To further control impact and impulse forces on a target, additional layers may be used, including a foam layer and a jet-clipping layer positioned between the shaped-charge and the target surface. Also provided are propellant driven liquid disrupters having special attenuating bodies to improve liquid jet column characteristics.

Abstract: An in vitro release test (IVRT) method and system is provided for drug release testing. The IVRT method, referred to herein as adaptive perfusion, employ tangential-flow filtration (TFF), where released drug products that are smaller than a molecular weight cutoff (MWCO) of a membrane filter pass therethrough into the permeate. Unreleased drug products are retained by the pores of the filter and are recirculated to a retentate reservoir. Fresh media is provided to the retentate in order to maintain a constant total volume for the sample as well as to maintain sink conditions for the drug release. Drug concentration in the retentate and permeate are evaluated by in situ monitoring with one or more sensors and/or by periodic removal of aliquots from the respective reservoirs. In some embodiments, the membrane filter can be conditioned prior to use in order to improve the accuracy, precision, or both of the subsequent testing.

Abstract: Disclosed are apparatus and methods for sensing and measurement of magnetic fields that are insensitive to temperature, and respond linearly to the magnitude of the magnetic field. In particular, the apparatus and methods include the use of a resistance network including at least one fluorinated graphene foam (FGF) magnetoresistive device. Measurement of a voltage drop across at least one FGF magnetoresistive device is correlated to either merely the presence of a magnetic field or for measurement of at least a scalar magnitude value of the magnetic field. The use of FGF affords both temperature-insensitivity and linear magnetic field responsivity.
