In this paper, we show that the piecewise linear finite element solution uh and the linear interpolation uI have superclose gradient for tetrahedral meshes, where most elements are obtained by dividing approximate parallelepiped into six tetrahedra. We then analyze a post-processing gradient recovery scheme, showing that the global L2 projection of ∇uh is a superconvergent gradient approximatio...

Consider two sets of strings, B (bad genes) and G (good genes), as well as two integers db and dg (db ≤ dg). A frequently occurring problem in computational biology (and other fields) is to find a (distinguishing) substring s of length L that distinguishes the bad strings from good strings, i.e., such that for each string si ∈ B there exists a length-L substring ti of si with d(s, ti) ≤ db (clo...

The results from the small scale application are encouraging. Our model successfully reproduces known behavior of the λ−switch on the basis of molecular level competition and resource constraints, without the need to assume protein-protein interactions between cI2 dimers and cI2 and RNA-polymerase. Even in the context of this well-known sub-system, however, few quantitative experimental results...

With the fast-growing graphical user interface (GUI) development workload in Internet industry, some work attempted to generate maintainable front-end code from GUI screenshots. It can be more suitable for using (UI) design drafts that contain UI metadata. However, fragmented layers inevitably appear drafts, which greatly reduces quality of generated code. None existing automated techniques det...

This paper studies how the potential duration of unemployment benefits affects early job search behavior and re-employment outcomes. We exploit an unexpected reform German insurance (UI) scheme in 2008, which increased benefit from 12 to 15 months for recipients age 50 54. Based on detailed survey data a difference-in-differences design, we estimate that one additional month reduces application...

In developing suitable numerical techniques for computational aero-acoustics, the DispersionRelation-Preserving (DRP) scheme by Tam and coworkers, and the optimized prefactored compact (OPC) scheme by Ashcroft and Zhang have shown desirable properties of reducing both dissipative and dispersive errors. These schemes, originally based on the finite difference, attempt to optimize the coefficient...
