Use of the Cook Airway Exchange Catheter to Facilitate Fiberoptic Intubation: Are We Trying to Solve a Problem

To the Editor:—In their report, Ayoub et al. found that advancing the endotracheal tube (ETT) into the trachea over the fiberoptic bronchoscope (FOB) fails in about one third of patients. They also found that by inserting a Cook Airway Exchange Catheter (Cook Critical Care, Bloomington, IN) (CAEC) alongside the FOB, tracheal intubation was successfully accomplished in these patients. They concl...

Marine biofouling: a sticky problem.

Organisms that colonise underwater surfaces, such as barnacle larvae and spores of algae, use a diverse array of biological 'glues' to provide both temporary and more permanent adhesion. The practical consequence of colonisation by these organisms is biofouling - something that has plagued mariners for years - causing increased drag and, in extreme cases, corrosion. Might there be a biological ...

A Honey Bee Algorithm To Solve Quadratic Assignment Problem

Assigning facilities to locations is one of the important problems, which significantly is influence in transportation cost reduction. In this study, we solve quadratic assignment problem (QAP), using a meta-heuristic algorithm with deterministic tasks and equality in facilities and location number. It should be noted that any facility must be assign to only one location. In this paper, first o...

Several ways to solve the MSO problem

The so called MSO-problem, – a simple superposition of two or more sinusoidal waves –, has recently been discussed as a benchmark problem for reservoir computing and was shown to be not learnable by standard echo state regression. However, we show that are at least three simple ways to learn the MSO signal by introducing a time window on the input, by changing the network time step to match the...
