LIZ-FACTORIZATION OF OPERATORS ON lx

Necessary and sufficent conditions are obtained for ¿(/-factorization of operators on /,. In particular it is shown that uniform invertibility of the compressions of the operator is not sufficient to insure an LU-factorization of the operator, thus answering a question of de Boor, Jia, and Pinkus. The question of when a bounded linear operator on lp, 1 < p <, oo, has an Li/-factorization has be...

Liz Rhoades: Single molecules tell many stories

R ecent advances in lasers and fl uo-rescent dyes have made it possible to observe individual proteins as they fold into their mature conforma-tion or bind to other proteins. Liz Rhoades is harnessing these techniques to answer questions about the biology of amyloid family proteins—whose aggregation is associated with neurodegenerative syndromes such as Parkinson's and Alzheim-er's disease (1)....

A Syndrome Featuring Defects

Three patients featuring a syndrome of defects of the heart, sternum, diaphragm, and anterior abdominal wall are presented. The striking similarity of the anomalies manifested by the 3 cases posed a question whether or not a recognized syndrome previously existed. In order to determine this, a search was made to find other such cases, and an attempt was made to establish a common embryologic pa...

Comparison of Bayley-2 and Bayley-3 scores at 18 months in term infants following neonatal encephalopathy and therapeutic hypothermia

AIM Neuroprotection trials for neonatal encephalopathy use moderate or severe disability as an outcome, with the Bayley Scales of Infant Development, Second Edition (Bayley-2) Index scores of <70 as part of the criteria. The Bayley Scales of Infant and Toddler, 3rd Development, Third Edition (Bayley-3) have superseded Bayley-2 and yield higher than expected scores in typically developing and hi...
