A Hospital-Based Program to Reduce Central Line-Associated Bloodstream Infections among Hospitalized Patients Receiving Hemodialysis Using a Central Venous Catheter for Vascular Access.

Central venous catheter (CVC) vascular access is common among patients on hemodialysis. CVC use carries a substantial risk of central line-associated bloodstream infections (CLABSIs), costly events that place patients at a high risk of mortality. Our hospital and dialysis organization developed a cooperative strategy to reduce the rate of CLABSI among hospitalized patients on hemodialysis with a CVC.

Fixed-weight on-line learning.

Conventional artificial neural networks perform functional mappings from their input space to their output space. The synaptic weights encode information about the mapping in a manner analogous to long-term memory in biological systems. This paper presents a method of designing neural networks where recurrent signal loops store this knowledge in a manner analogous to short-term memory.

Sizing dielectric spheres and cylinders by aligning measured and computed resonance locations: algorithm for multiple orders.

An algorithm for determining the size of dielectric spheres and cylinders by aligning measured and computed resonance locations is presented. The orders of the resonance locations need not be known a priori. The algorithm is applicable to several types of scattering and emission spectra of spheres and cylinders if the index of refraction including dispersion is known and uniform, or nearly uniform, throughout the sphere or cylinder.
