Visualization tools of different languages offer its users with a needed set of features allowing them to animate how programs of such languages work. Constraint Handling Rules (CHR) is currently used as a general purpose language. This results in having complex programs with CHR. Nevertheless, CHR is still lacking on visualization tools. With Constraint Handling Rules (CHR) being a high-level ...

Interesting subclasses of CHR are still Turing-complete: CHR with only one kind of rule, with only one rule, and propositional refined CHR. This is shown by programming a simulator of Turing machines (or Minsky machines) within those subclasses. Single-headed CHR without host language and propositional abstract CHR are not Turing-complete.

BACKGROUND The purpose of this study was to evaluate the role of spectral domain optical coherence tomography (SD-OCT), MP-1 microperimetry, and fundus autofluorescence imaging for planning surgical procedures in combined hamartomas of the retina and retinal pigment epithelium (CHR-RPE) and following epiretinal membrane removal. METHODS In an interventional retrospective case series, six cons...

This paper investigates the relationship between the Logical Algorithms language (LA) of Ganzinger and McAllester and Constraint Handling Rules (CHR). We present a translation schema from LA to CHR: CHR with rule priorities, and show that the meta-complexity theorem for LA can be applied to a subset of CHR via inverse translation. Inspired by the high-level implementation proposal for Logical A...

BACKGROUND Disruptions in thalamic functional connectivity have been observed in people with schizophrenia and in youth at clinical high risk (CHR) of psychosis. However, the impact of environmental risk factors for psychosis on thalamic dysconnectivity is poorly understood. We tested whether thalamic dysconnectivity is related to patterns of cannabis use in a CHR sample. METHODS 162 CHR and ...

Constraint Handling Rules (CHR) is both an effective concurrent declarative constraint-based programming language and a versatile computational formalism. While conceptually simple, CHR is distinguished by a remarkable combination of desirable features: – a semantic foundation in classical and linear logic, – an effective and efficient sequential and parallel execution model – guaranteed proper...

PURPOSE To determine the maximum tolerated dose, dose-limiting toxicity, pharmacokinetics, and preliminary therapeutic activity profile of CHR-2797 (tosedostat), a novel, orally bioavailable inhibitor of the M1 family of aminopeptidases with antiproliferative and antiangiogenic activity in vitro. EXPERIMENTAL DESIGN A phase I study of accelerated titration design that escalated through nine d...

Let $G=(V(G),E(G))$ be a simple, finite and undirected graph of order $n$. A $k$-vertex weightings of a graph $G$ is a mapping $w: V(G) to {1, ldots, k}$. A $k$-vertex weighting induces an edge labeling $f_w: E(G) to N$ such that $f_w(uv)=w(u)+w(v)$. Such a labeling is called an {it edge-coloring k-vertex weightings} if $f_{w}(e)not= f_{w}(echr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39'...
