Electro-active lenses with raised resistive bridges
Resistive bridges can connect many ring electrodes in an electro-active lens with a relatively small number of buss lines. These resistors are usually large to prevent excessive current consumption. Conventionally, they are disposed in the same plane as the ring electrodes, which means that the ring electrodes are spaced farther apart or made discontinuous to accommodate the resistors. But spacing the ring electrodes farther apart or making them discontinuous degrades the lens's optical quality. Placing the ring electrodes and resistors on layers separated by an insulator makes it possible for the ring electrodes to be closer together and continuous with resistance high enough to limit current consumption. It also relaxes constraints on feature sizes and placement during the process used to make the lens. And because the resistors and electrodes are on different planes, they can be formed of materials with different resistivities. |

Steel wire rope, coated steel wire rope and belt comprising steel wire rope
A steel wire rope is presented for use in elevators and lifting applications. The steel wire rope contains a core surrounded by multiple strands. The outer filaments of the core and the outer filaments of the strands are likely to contact one another during use. The outer steel filaments of the core have an average Vickers hardness that is at least 50 Vickers hardness numbers lower than that of the outer filaments of the strands. As the hardness of the outer filaments of the core is substantially lower than that of the outer filaments of the strands, those softer filaments will preferentially abrade away during use. In this way the core is sacrificed while preserving the integrity of the outer filaments of the strands. The use of this ‘sacrificial core’ results in a higher residual breaking load after use. |

Methods of lowering the error rate of massively parallel DNA sequencing using duplex consensus sequencing
Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand. This method uniquely capitalizes on the redundant information stored in double-stranded DNA, thus overcoming technical limitations of prior methods utilizing data from only one of the two strands. |
