CHR (Constraint Handling Rules) is a committed-choice rulebased language that was originally intended for writing constraint solvers. Over time, CHR is used more and more as a general-purpose programming language. In companion paper [12] we show that it is possible to write the classic union-find algorithm and variants in CHR with bestknown time complexity, which is believed impossible in Prolo...
With the wide expansion of multiprocessor architectures, the analysis and reasoning for programs under weak memory models has become an important concern. This work presents an original constraint solver for detecting program behaviors respecting a particular memory model. It is implemented in Prolog using CHR (Constraint Handling Rules). The CHR formalism provides a convenient generic solution...
BACKGROUND Despite advances that the psychosis "clinical high-risk" (CHR) identification offers, risk of stigma exists. Awareness of and agreement with stereotypes has not yet been evaluated in CHR individuals. Furthermore, the relative stigma associated with symptoms, as opposed to the label of risk, is not known, which is critical because CHR identification may reduce symptom-related stigma. ...
BACKGROUND The individual risk of developing psychosis after being tested for clinical high-risk (CHR) criteria (posttest risk of psychosis) depends on the underlying risk of the disease of the population from which the person is selected (pretest risk of psychosis), and thus on recruitment strategies. Yet, the impact of recruitment strategies on pretest risk of psychosis is unknown. METHODS ...
B-myb belongs to a group of cell cycle genes whose transcription is repressed in G0/early G1 through a binding site for the transcription factor E2F. Here, we show that the B-myb repressor element is specifically recognised by heterodimers consisting of DP-1 and E2F-1, E2F-3 or E2F-4. Surprisingly, E2F-mediated repression is dependent on a contiguous corepressor element that resembles the CHR p...

BACKGROUND Phyllodes tumors are uncommon breast tumors that account for less than 0.5% of all breast malignancies. After metastases develop, the prognosis is poor, with very few patients living more than 1 year. The biology of this unusual cancer is not understood and, consequently, no potential targets for treatments are currently available. There has been an exponential increase in the number...
In the past few years, several successful approaches to termination analysis of Constraint Handling Rules (CHR) have been proposed. In parallel to these developments, for termination analysis of Logic Programs (LP), recent work has shown that a stronger focus on the analysis of the cycles in the strongly connected components (SCC) of the program is very beneficial, both for precision and effici...
CHR Grammars (CHRG) are a recent constraint-based grammar formalism added on top of CHR analogously to the way Definite Clause Grammars are defined and implemented over Prolog. A CHRG executes as an error robust bottom-up parser, and the formalism provides several advantages for natural language analysis reported elsewhere [4–6]. A notable property is CHRG’s inherent ability to handle abduction...
