Abstract:
This disclosure describes techniques for analyzing statistical quality of bitstrings produced by a physical unclonable function (PUF). The PUF leverages resistance variations in the power grid wires of an integrated circuit. Temperature and voltage stability of the bitstrings are analyzed. The disclosure also describes converting a voltage drop into a digital code, wherein the conversion is resilient to simple and differential side-channel attacks.
Abstract:
The present invention relates to the use of neutral lipids, including triglycerides, diglycerides and monoglycerides which may be used to increase neutral lipids (lipid stores and/or lipid droplets) and neutral lipid stores in order to regulate (in particular, induce) autophagy and treat and/or prevent autophagy related disease states and/or conditions. In one embodiment, the invention relates to the use of neutral lipids and/or TRIM proteins which may be used to regulate (in particular, induce) autophagy, target autophagic substrates and treat and/or prevent autophagic disease states and/or conditions.

Abstract:
This disclosure describes, in one aspect, a method for preparing DNA molecule for sequencing. Generally, the method includes fragmenting the DNA molecule into double-stranded fragments; amplifying at least a portion of the double-stranded fragments; circularizing the fragments so that the first end of the fragment comprises a first loop connecting the strands and the second end of the fragment comprises a second loop connecting the strands; annealing a first sequencing primer to the first loop oriented to sequence at least a portion of one strand of the fragment; and annealing a second sequencing primer to the second loop oriented to sequence at least a portion of the other strand of the fragment. In another aspect, this disclosure describes a method for sequencing a DNA molecule. Generally, the method includes fragmenting the DNA molecule into double-stranded fragments; amplifying at least a portion of the double-stranded fragments; circularizing the fragments so that the first end of the fragment comprises a first loop connecting the strands and the second end of the fragment comprises a second loop connecting the strands; and sequencing at least one of the DNA strands.
Abstract:
The invention provides methods and materials for decontamination of surfaces and fabrics, such as non-woven fabrics, that are contaminated with infestations of microorganisms such as bacteria. Biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group can be used to decontaminate infested surfaces in the presence of oxygen and, optionally, illumination. Fibers incorporating biocidal oligomers having conjugated oligo-(aryl/heteroaryl ethynyl) structures and comprising at least one cationic group, wherein the oligomer is physically associated with or covalently bonded to, or both, the fiber-forming polymer can be used to form non-woven mats. Biocidal non-woven mats prepared by methods of the invention, incorporating the biocidal oligomers, can be used to suppress bacterial growth in wound and surgical dressings and personal hygiene products.
Abstract:
The invention provides methods of treating nitric oxide/cGMP pathway-cell adhesion disorders and related pharmaceutical compositions, diagnostics, screening techniques and kits. In one embodiment, the invention relates to a method for down-regulating α 4 β 1 -integrin affinity and inhibiting and reversing adhesion formation in patients or subjects in need using a nitric oxide donor.
Abstract:
A device for coating dry powder microparticles onto a surfacemay include a jet mill configured to mill dry powder particles into microparticles having a desired aerodynamic diameter and to deaggregate the microparticles, a feed hopper structured and arranged to feed dry powder particles to the jet mill, a surface configured to receive dry powder microparticles and an exit nozzle associated with the jet mill. The exit nozzle may be arranged to direct deaggregated micronized dry powder particles from the jet mill to the surface to be coated. The device may further include a holder structured and arranged to hold an item, wherein the item includes the surface. In some aspects of the device, the item may be a film.
Abstract:
The present invention relates to a system and method for controlling peptide display valency on virus-like particles (VLPs), especially including MS2 VLPs. In this method, large amounts of wild-type and low quantities of single-chain dimer coat proteins may be produced from a single RNA. Valency is controlled in immunogen (vaccine) production by providing a system that allows the production of large amounts of wild-type and low quantities of single-chain dimer coating proteins from a single RNA, allowing facile adjustment of display valency levels on VLPs, especially MS2 VLPS over a wide range, from few than one- on average- to as many as ninety per particle. This facilitates the production of immunogens and vaccines, including VLPs exhibiting low valency. Nucleic acid constructs useful in the expression of virus-like particles are disclosed, comprised of a coat polypeptide of MS2 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates MS2 niRNA. Nucleic acid constructs are also disclosed which are useful in the expression of virus-like particles comprised of a coat polypeptide of PP7 modified by insertion of a heterologous peptide, wherein the heterologous peptide is displayed on the virus-like particle and encapsidates PP7 mRNA.
