Circuit failure prediction predicts the occurrence of a circuit failure before errors actually appear in system data and states. This is in contrast to classical error detection where a failure is detected after errors appear in system data and states. Circuit failure prediction is performed during system operation by analyzing the data collected by sensors(More)
Circuit failure prediction is used to predict occurrences of circuit failures, during system operation, before errors appear in system data and states. This technique is applicable for overcoming major scaled-CMOS reliability challenges posed by aging mechanisms such as Negative-Bias-Temperature-Instability (NBTI). This is possible because of the gradual(More)
In this paper, statistical models for the efficient analysis of interconnect delay and crosstalk noise in the presence of back-end process variations are developed. The proposed models enable closed-form computation of means and variances of interconnect-delay, crosstalk-noise peak, and coupling-induced-delay change for given magnitudes of variation in(More)
Circuit failure prediction predicts the occurrence of a circuit failure before errors actually appear in system data and states. This is in contrast to traditional error detection where a failure is detected after errors appear in system data and states. Circuit failure prediction can be performed in multiple ways -the basic principle is to insert a wide(More)
In this paper, we develop an approach for statistical modeling of crosstalk noise and dynamic delay degradation in coupled RC interconnects under process variations. The proposed model enables closed-form computation of mean and variance of noise peak and worst case dynamic delay for given variabilities in physical dimensions. We compare the proposed model(More)
INTRODUCTION A 3-year-old child, weighing 8 kg, presented with patent ductus arteriosus (PDA) and interrupted inferior vena cava (IVC). The patient underwent successful PDA device closure via transjugular route after failing attempt at femoral venous route. CASE SUMMARY PDA device closure was attempted via femoral venous route but could not be(More)
Being a reflection of the degree of global tissue anoxia, serum lactate levels therefore can be used as a marker of organ damage and eventual outcome. A statistically significant association was observed between serum lactate levels and subsequent mortality and morbidity in critically ill adults, children, and neonates. In cardiac critical care,(More)
OBJECTIVE To delineate risk factors for failure of extubation in the operating room among pediatric cardiac surgery patients. DESIGN Prospective, observational study. SETTING Single center, tertiary care, teaching hospital. PARTICIPANTS The study comprised 448 congenital cardiac surgery patients who were enrolled for intended extubation in the(More)
Pseudoaneurysm of ascending aorta is an infrequent but well-recognized and potentially fatal complication after cardiac surgeries. The complication can develop early, delayed or late, and the presentation is also varied. We are presenting here two cases of pseudoaneurysm of ascending aorta following cardiac surgery that were successfully managed by the(More)
