We propose four finite-length scaling laws to predict the frame error rate (FER) performance in waterfall region of spatially-coupled low-density parity-check code ensembles under full belief propagation (BP) decoding with a limit on number iterations and law for sliding window decoding, also limited iterations. The BP provide choice between accuracy computational complexity; good balance them ...

We propose two enhancements of quasi-Newton methods used to accelerate coupling iterations for partitioned fluid-structure interaction. Quasi-Newton have been established as flexible, yet robust, efficient and accurate multi-physics simulations in general. The library preCICE provides several variants, the so-called IQN-ILS method being most commonly used. It uses input output differences coupl...

Abstract Background Interference screw is commonly used for graft fixation in anterior cruciate ligament (ACL) reconstruction. However, previous studies had reported that the insertion of interference screws significantly caused laceration. The purposes this study were to (1) quantitatively evaluate laceration from one single PEEK screws; and (2) determine whether different types sutures reduce...

Motivated by recent experiments on DNA torsion-force-extension characteristics we consider the writhing geometry of open stiff molecules. We exhibit a cyclic motion which allows arbitrarily large twisting of the end of a molecule via an activated process. This process is suppressed for forces larger than femto-Newtons which allows us to show that experiments are sensitive to a generalization of...
