For more than 40 years, the Institute for Scientific Information (ISI, now part of Thomson Reuters) produced the only available bibliographic databases from which bibliometricians could compile largescale bibliometric indicators. ISI’s citation indexes, now regrouped under the Web of Science (WoS), were the major sources of bibliometric data until 2004,(More)
VectorBase (http://www.vectorbase.org) is a NIAID-supported bioinformatics resource for invertebrate vectors of human pathogens. It hosts data for nine genomes: mosquitoes (three Anopheles gambiae genomes, Aedes aegypti and Culex quinquefasciatus), tick (Ixodes scapularis), body louse (Pediculus humanus), kissing bug (Rhodnius prolixus) and tsetse fly(More)
Reliable systems have always been built out of unreliable components [1]. Early on, the reliable components were small such as mirrored disks or ECC (Error Correcting Codes) in core memory. These systems were designed such that failures of these small components were transparent to the application. Later, the size of the unreliable components grew larger(More)
Differential equations are used in modeling diverse system behaviors in a wide variety of sciences. Methods for estimating the differential equation parameters traditionally depend on the inclusion of initial system states and numerically solving the equations. This paper presents Smooth Functional Tempering, a new population Markov Chain Monte Carlo(More)
Aortic allograft fibrocalcification and valvular insufficiency have been observed in patients less than 3 years of age at initial replacement of the left ventricular outflow tract. From June 1985 through May 1992, 47 children have undergone aortic root replacement with cryopreserved aortic valve allografts. Thirty-three children were 3 years of age or older(More)
As the capabilities and service levels of enterprise database systems have evolved, they have collided with incumbent technologies such as TP-Monitors or Message Oriented Middleware (MOM). We believe this trend will continue and have architected the upcoming release of SQL Server to advance this technology trend. This paper describes the Service Oriented(More)
Over the course of the last 5 years, we have instituted peritoneal dialysis on 26 (7.7%) of 338 complex postoperative cardiac bypass cases. The mean age of dialysis patients was 0.64±0.75 years with a range of 0.1–2.5 years. The indications for the start of dialysis were oliguria (15 cases), fluid overload (three cases), hyperkalemia (one case), and anuria(More)
Congenital right posterolateral (Bochdalek's) diaphragmatic hernia usually has clinical manifestations different from those of left Bochdalek's hernia; it often masquerades as a pleural effusion, an asymptomatic intrathoracic mass, or an intestinal obstruction. The primary reason for the difference in symptoms is the presence of the liver on the right,(More)
BACKGROUND Congenital supravalvar aortic stenosis (SVAS) is an arteriopathy associated with Williams-Beuren syndrome and other elastin gene deletions. Our objectives were to review outcomes of congenital SVAS repair and to compare prosthetic patch repair techniques to all-autologous slide aortoplasty. METHODS Congenital SVAS repairs from 1988 to 2008 were(More)
BACKGROUND Colon perforation has been previously described after solid organ transplantation. Since the inception of the lung transplant program at the University of Colorado 60 isolated lung transplantations have been performed. Four of these patients have suffered spontaneous colonic perforation. METHODS The case history of each lung transplant patient(More)
