We present PaSAT, a parallel implementation of a Davis-Putnam-style propositional satisfiability checker incorporating dynamic search space partitioning, intelligent backjumping, as well as lemma generation and exchange; the main focus of our implementation is on speeding up SAT-checking of propositional encodings of real-world combinatorial problems. We investigate and analyze the speed-ups ob...

People with schizophrenia have impairments of target-speech recognition (TSR) in noisy environments with multiple people talking. This study investigated whether the TSR impairment in schizophrenia is associated with their impaired auditory working memory or certain psychotic symptoms. Thirty participants with schizophrenia (mean age= 35.2 ± 12.7 years) and 30 demographics-matched healthy contr...
BACKGROUND There is need for a cognitive test battery that can be easily used in clinical practice to detect or monitor cognitive performance in patients with multiple sclerosis (MS). In order to conduct, in this patient group, a preliminary investigation of the validity and utility of a brief computerized battery, the Cognitive Drug Research (CDR) battery, we longitudinally assessed cognition ...
OBJECTIVES Dalfampridine exerts beneficial effects on walking ability in a subgroup of patients with multiple sclerosis (MS). These patients are termed "responders". Here, we investigated whether the responder status with respect to mobility measures would determine whether dalfampridine treatment exerts a beneficial effect on other MS symptoms. We therefore assessed walking ability, upper limb...
