This paper presents new linearity-preserving nodal limiters for enforcing discrete maximum principles in continuous (linear or bilinear) finite element approximations to transport problems with steep fronts. In the process of algebraic flux correction, the oscillatory antidiffusive part of a high-order base discretization is decomposed into a set of internodal fluxes and constrained to be local...

This paper presents a novel approach, called MODS, to build an accurate time evolving classifier from multiple one-class data streams learning time evolving classifier. Our proposed MODS approach works in two steps. In the first step, we first construct local one-class classifiers on the labeled positive examples from each sub-data stream respectively. We then collect the informative examples (...

Many ecosystems develop strikingly regular spatial patterns because of small-scale interactions between organisms, a process generally referred to as spatial self-organization. Self-organized spatial patterns are important determinants of the functioning of ecosystems, promoting the growth and survival of the involved organisms, and affecting the capacity of the organisms to cope with changing ...

485 An information-theoretic optimization principle is proposed for the development of each processing stage of a multilayered perceptual network. This principle of "maximum information preservation" states that the signal transformation that is to be realized at each stage is one that maximizes the information that the output signal values (from that stage) convey about the input signals value...

Maximum bound principle (MBP) is an important property for a large class of semilinear parabolic equations, in the sense that time-dependent solution equation with appropriate initial and boundary conditions nonlinear operator preserves all time uniform pointwise absolute value. It has been challenging problem on how to design unconditionally MBP-preserving high-order accurate time-stepping sch...

Self-propulsion and directed movement of nanoand micro-particles can in principle provide novel components for applications in microrobotics and MEMS. Our research involves the design of catalytic propulsion systems and the control of colloidal movement based on this principle. We have designed autonomous nanomotors that mimic biological motors by using catalytic reactions to generate forces de...

We describe a surgical procedure used to achieve glenothoracic fusion after one-stage radical, near total scapulectomy for primary or secondary malignant lesions in six patients. The aim was complete excision of the lesion and preservation of the glenoid to provide a fulcrum for movement of the arm. Post-operative assessment involved determination of the range of movement and the application of...
