It is important for robot designers to know how to make robots that interact effectively with humans. One key dimension is robot appearance and in particular how humanlike the robot should be. Uncanny Valley theory suggests that robots look uncanny when their appearance approaches, but is not absolutely, human. An underlying mechanism may be that appearance(More)
i ABSTRACT Coarse-Grained Reconfigurable Architectures (CGRA) are a promising fabric for improving the performance and power-efficiency of computing devices. CGRAs are composed of components that are well-optimized to execute loops and rotating register file is an example of such a component present in CGRAs. Due to the rotating nature of register indexes(More)
GATA and Friend of GATA (FOG) form a transcriptional complex that plays a key role in cardiovascular development in both fish and mammals. In the present study we demonstrate that the basic helix-loop-helix transcription factor Atonal homolog 8 (Atoh8) is required for development of the heart in fish but not in mice. Genetic studies reveal that Atoh8(More)
OBJECTIVES To compare the attributes and clinical outcomes of patients with cardiac arrest in the setting of drug overdose (OD) to patients with cardiac arrest from non-drug related etiologies. METHODS We utilized a US inpatient cardiac arrest registry used to study targeted temperature management (TTM) to identify patients with cardiac arrest in the(More)
The secreted protein CCBE1 is required for lymphatic vessel growth in fish and mice, and mutations in the CCBE1 gene cause Hennekam syndrome, a primary human lymphedema. Here we show that loss of CCBE1 also confers severe anemia in midgestation mouse embryos due to defective definitive erythropoiesis. Fetal liver erythroid precursors of Ccbe1 null mice(More)
Elderly-onset ulcerative colitis (EO-UC) is recognized as a distinct subpopulation of UC. To our knowledge, there have been no nationwide studies of EO-UC populations in the USA. We aim to characterize differences in presentation at diagnosis and clinical course between EO-UC and adult-onset UC (AO-UC) patients in a national cohort. Complete medical records(More)
Chronic pain arising from various pathological conditions such as osteoarthritis, low back or spinal injuries, cancer, and urological chronic pelvic pain syndromes presents significant challenges in diagnosis and treatment. Specifically, since the underlying cause of these pain syndromes is unknown or heterogeneous, physicians diagnose and treat patients(More)
Aim: To evaluate and intercompare quantitatively, the prevalence of habitual psychoactive substance users alcohol, nicotine and betel nut in the individuals and to evaluate and intercompare clinically, the prevalence of oral mucosal lesions in habitual psychoactive substance users. Methodology: A total of 81 subjects in the age range 25 to 55 years, who(More)
