Abstract: Real-world data may not be sparse in a fixed basis, and current high-performance recovery algorithms are slow to converge, which limits compressive sensing (CS) to either non-real-time applications or scenarios where massive back-end computing is available. Presented herein are embodiments for improving CS by developing a new signal recovery framework that uses a deep convolutional neural network (CNN) to learn the inverse transformation from measurement signals. When trained on a set of representative images, the network learns both a representation for the signals and an inverse map approximating a greedy or convex recovery algorithm. Implementations on real data indicate that some embodiments closely approximate the solution produced by state-of-the-art CS recovery algorithms, yet are hundreds of times faster in run time.
Abstract: Embodiments of the invention are directed to Ubx-fusion molecules that maintain their mechanical strength and properties even after being fused with Ubx. Ubx fusions with VEGF and other growth factors, cell signaling proteins, and cell binding proteins can be used to induce angiogenesis. Ubx fibers and mesh, embedded within a tissue engineering scaffold, induce formation of vasculature within the scaffold. The presence of vasculature is necessary to provide oxygen and nutrients to other cells growing within the scaffold.

Abstract: Compositions and methods for highly specific nucleic acid probes and primers are provided. The probe system comprises a complement strand and a protector stand that form a partially double-stranded probe. The reaction standard free energy of hybridization between the probe and target nucleic acid as determined by Expression 1 (?G°rxn=?G°t-TC??G°nh-PC+(?G°v-TC??G°h-PC)) is from about ?4 kcal/mol to about +4 kcal/mol. Alternatively, the reaction standard free energy of hybridization between the probe and target nucleic acid is determined by Expression 1 to be within 5 kcal/mol of the standard free energy as determined by Expression 2 (?R? ln(([P]0?[C]0)/[C]0)]), where the [P]0 term of Expression 2 equals the concentration of the protector strand and the [C]0 term of Expression 2 equals the concentration of the complement strand. In addition, a method for on-the-fly fine tuning of a reaction using the present probe is provided.

Abstract: The present disclosure describes a genetically engineered a KASIII-independent fatty acid biosynthetic pathway that makes use of the promiscuous nature of the rest of the FAS enzymes (3-ketoacyl-ACP synthetase, 3-ketoacyl-ACP reductase, 3-hydroxyacyl ACP dehydrase, enoyl-ACP reductase) to bypass the KASIII step by providing a Co-A precursor of two or higher than two carbons (such as the four carbon butyryl-CoA) as the starting molecule. Since many CoA-based starter molecules can be supplied for the fatty acid synthesis, much more diversified products can be obtained with various carbon-chain lengths. As such, this disclosure will serve as a powerful and efficient platform to produce low to medium chain length products carrying many different functional groups.
