Large-scale internet services aim to remain highly available and responsive in the presence of unexpected failures. Providing this service often requires monitoring and analyzing tens of millions of measurements per second across a large number of systems, and one particularly effective solution is to store and query such measurements in a time series(More)
BACKGROUND Despite clinical and technical advances, acute aortic dissection carries high operative mortality. This study was designed to establish whether this is influenced by institution and surgeon volume. METHODS Outcomes of 5,184 patients (mean age, 60.3 years; 65.9% male) diagnosed with acute aortic dissection from the Nationwide Inpatient Sample(More)
The bending performance of fabric air beams varies significantly from conventional beams. Both are dependent upon the constitutive relations of the material, but air beams are further dependent upon the thermodynamics of the internal air. As the governing energy balance demonstrates, air beam bending is dependent upon strain energy and PVwork (air(More)
OBJECTIVES The objective of this study was to investigate the impact of bilateral internal mammary artery (BIMA) on early outcomes after coronary artery bypass grafting. DESIGN Retrospective database analysis. SETTING US hospitals. PATIENTS 1 526 360 patients (mean age 65 years, 73% male) from the Nationwide Inpatient Sample from 2002-2008 who(More)
OBJECTIVE The aim of this study was to determine the effect of pulmonary artery catheterization on clinical outcomes after cardiac surgery in higher-risk patients. DESIGN Retrospective national database analysis. SETTING U.S. hospitals. PARTICIPANTS A weighted sample of 2,063,337 patients undergoing cardiac surgery identified from the Nationwide(More)
OBJECTIVES The objective of this study was to compare the early outcomes of off-pump and on-pump surgeries in high-risk patient groups. METHODS The outcomes of 83,914 high-risk patients undergoing off-pump or on-pump isolated coronary bypass surgery identified from the Nationwide Inpatient Sample from 2005 to 2010 were compared using propensity analysis.(More)
OBJECTIVES The objective of this study was to assess the impact of robotic approaches on outcomes of coronary bypass surgery. DESIGN Retrospective national database analysis. SETTING United States hospitals. PARTICIPANTS A weighted sample of 484,128 patients undergoing isolated coronary artery surgery identified from the Nationwide Inpatient Sample(More)
OBJECTIVES The objective of this study was to quantify the impact of heparin-induced thrombocytopenia (HIT) on outcomes after cardiac surgery. DESIGN Retrospective analysis of national database. SETTING United States hospitals. PARTICIPANTS Patients identified from 186,771 discharge records undergoing cardiac surgery from the Nationwide Inpatient(More)
The Oxygen Kiosk Network (OK-Net) Project (Van Kleek, 2003) has deployed its first batch of interactive touchscreen kiosks within the MIT CSAIL laboratory. These kiosks are strategically placed in locations where people tend to congregate, such as lounges and elevator lobbies. The kiosks currently run an application known as SKINNI (Kleek et al., 2004), the(More)
ABCA12 mutations disrupt the skin barrier and cause harlequin ichthyosis. We previously showed Abca12(-/-) skin has increased glucosylceramide (GlcCer) and correspondingly lower amounts of ceramide (Cer). To examine why loss of ABCA12 leads to accumulation of GlcCer, de novo sphingolipid synthesis was assayed using [(14)C]serine labeling in ex vivo skin(More)
