The stage after the Burrows-Wheeler Transform (BWT) has a key function inside the Burrows-Wheeler compression algorithm as it transforms the BWT output from a local context into a global context. This paper presents the Incremental Frequency Count stage, a post-BWT stage. The new stage is paired with a run length encoding stage between the BWT and entropy(More)
One-day-old and 7-day-old specific-pathogen-free chickens were orally infected with a field isolate of Salmonella enteritidis phage type 13A. Chickens were sequentially euthanatized at various intervals until 42 days of age, and selected tissues were collected for microscopic evaluation. Eleven of 53 chickens (21%) infected at 1 day of age and 2 of 28(More)
Summary form only given. A new stage for the Burrows-Wheeler compression algorithm (BWCA) is presented, called incremental frequency count (IFC), which, together with a run length encoding (RLE) stage, is located between the Burrows-Wheeler transform (BWT) and the entropy coding (EC) stage of the algorithm. The IFC stage offers a high throughput similar to(More)
STUDY OBJECTIVE To determine the efficacy of intravenous aminophylline in the treatment of patients hospitalized for exacerbation of chronic obstructive pulmonary disease. DESIGN Randomized, double-blind, placebo-controlled trial during the first 72 hours of hospitalization. PATIENTS Thirty patients admitted from the emergency room or walk-in clinic(More)
The peptide, succinyl-alanyl-alanyl-prolyl-valine chloromethylketone (SPCK), a synthetic inhibitor of elastase, was covalently attached to human albumin microspheres (HAM) and administered intratracheally to hamsters 15 min and 8 h prior to the instillation of porcine pancreatic elastase. Pressure-volume relationships and histologic examination of excised(More)
Coronary stenting was performed in 15 selected patients with cardiogenic shock, with favorable clinical and angiographic outcomes. This experience suggests that coronary stenting may play an important adjunctive role in the management of cardiogenic shock and may improve outcome beyond that achieved with balloon angioplasty alone.
One- and 7-day-old specific pathogen-free chickens were artificially infected with a field isolate of Salmonella enteritidis, phage type 13A. At intervals up to 42 days of age, birds were killed and liver, lung, spleen, brain, yolk sac, testis or ovary, duodenum, jejunum, ileum, caecum and colon collected for culture. In chickens infected at one day of age(More)
