STUDY OBJECTIVES Sleep after learning often benefits memory consolidation, but the underlying mechanisms remain unclear. In previous studies, we found that learning a visuomotor task is followed by an increase in sleep slow wave activity (SWA, the electroencephalographic [EEG] power density between 0.5 and 4.5 Hz during non-rapid eye movement sleep) over(More)
Animal acoustic communication often takes the form of complex sequences, made up of multiple distinct acoustic units. Apart from the well-known example of birdsong, other animals such as insects, amphibians, and mammals (including bats, rodents, primates, and cetaceans) also generate complex acoustic sequences. Occasionally, such as with birdsong, the(More)
OBJECTIVES The goal of this study was to determine, in patients with a recent myocardial infarction (MI) and residual wall motion abnormalities within the distribution of the infarct-related artery, whether normal perfusion by myocardial contrast echocardiography (MCE) would accurately predict recovery of segmental left ventricular (LV) function.

BACKGROUND Numerous studies have demonstrated that patients with diabetes have higher rates of restenosis, late myocardial infarction, and late death after percutaneous coronary interventions (PCI). However, it remains unclear whether patients with diabetes mellitus also have an increased hazard for early death after either elective or urgent PCI. METHODS(More)
OBJECTIVES We sought to determine the relative accuracy of myocardial contrast echocardiography (MCE) and low-dose dobutamine echocardiography (LDDE) in predicting recovery of left ventricular (LV) function in patients with a recent anterior wall myocardial infarction (MI). BACKGROUND Left ventricular dysfunction after acute MI may be secondary to(More)
UNLABELLED Prompt myocardial reperfusion is the therapeutic goal for patients presenting with acute myocardial infarction (AMI). However, there remains a paucity of clinical data from single centers solely dedicated to a catheter-based reperfusion strategy. Therefore, we sought to identify significant predictors of in-hospital mortality, to determine the(More)
The goal of the Adaptive Agents in Cultural Contexts symposium was to investigate agents and environments for behavior in social and cultural contexts and for realistic adaptation of such agents to changing situations. Computational human behavior models, in extending a conventional information-processing approach, face two complex problems: adaptation and(More)
BACKGROUND In the Heart Outcomes Prevention Evaluation (HOPE) Study, the angiotensin-converting enzyme (ACE) inhibitor ramipril was shown to significantly reduce the relative risk of stroke by 32% in high-risk cardiovascular patients (P < 0.001). However, the study did not examine the economic implications of these findings. OBJECTIVE The purpose of this(More)
