Neuropsychiatric (NP) manifestations pose diagnostic and therapeutic challenges in systemic lupus erythematosus (SLE). Less than one-third of these events can be directly attributed to SLE; accordingly attribution to SLE remains a considerable challenge. Increased generalized SLE disease activity or damage, previous or concurrent major neuropsychiatric SLE (NPSLE) events, and persistently posit...

A significant cost in PPM data compression (and often the major cost) is the provision and efficient coding of escapes while building contexts. This paper presents some recent work on eliminating escapes in PPM compression, using bit-wise compression with binary contexts. It shows that PPM without escapes can achieve averages of 2.5 bits per character on the Calgary Corpus and 2.2 bpc on the Ca...

An environment is a set of name-value bindings, maintained for a particular user, tha t are provided to a process at runtime. This can provide a great deal of flexibility in tai loring the behavior of programs to a particular user's preferences. It can also serve as a simple me ans of interprocess communication. To be useful, however, the environment must take into ac count the natural structur...

Historically, Markovian predictors have been very successful in predicting branch outcomes. In this work we propose a hybrid scheme that employs two Prediction by Partial Matching (PPM) Markovian predictors, one that predicts based on local branch histories and one based on global branch histories. The two independent predictions are combined using a neural network. On the CBP-2 traces the prop...
