We describe a new data format for storing triangular and symmetric matrices called RFP (Rectangular Full Packed). The standard two dimensional arrays of Fortran and C (also known as full format) that are used to store triangular and symmetric matrices waste half the storage space but provide high performance via the use of level 3 BLAS. Packed format arrays fully utilize storage (array space) b...

We show that if a sequence of trees T1, T2, ..., Tn−1 can be packed into Kn then they can be also packed into any n-chromatic graph.

Sodium, potassium, water, and the mean corpuscular haemoglobin concentration were determined in the packed erythrocytes of children with severe thalassaemia. The concentration of sodium in the packed red cells was higher than normal in a significant proportion of children with thalassaemia whereas potassium in the packed cells and sodium and potassium in the plasma were normal. On average, the ...

BACKGROUND Transfusion of human blood stored for more than 2 weeks is associated with increased mortality and morbidity. During storage, packed erythrocytes progressively release hemoglobin, which avidly binds nitric oxide. We hypothesized that the nitric oxide mediated hyperemic response after ischemia would be reduced after transfusion of packed erythrocytes stored for 40 days. METHODS AND ...

for the first time this study reported the success of using nanocrystalline hexagonal close-packed (hcp) nickel (ni) modified composite graphite (cg) electrode (hcp-nano ni/cg) for the electrocatalytic oxidation of glycerol in alkaline medium (0.1 m koh). the hcp-nano ni/cg electrode had an improve response and specificity on the electrocatalytic oxidation of glycerol over the bare cg. the elec...

the oxidation of ferrous iron (fe2+) in solution using acidithiobacillus ferrooxidans has industrial applications exclusively in the regeneration of ferric iron (fe3+) as an oxidizing agent for the removal of hydrogen sulfide from waste gases, desulfurization of coal, leaching of non-ferrous metallic sulfides and treatment of acid mine drainage. the aim of this investigation was to increase the...

BACKGROUND Blood transfusion is associated with side effects caused by residual leukocytes in blood and blood components. Using leukodepleted blood components can decrease some of these adverse effects. Among the various methods to remove leukocytes in blood components, prestorage leukoreduction has been most efficient, but the evidence of clinical side effects awaits further studies. We evalua...

OBJECTIVES Nasal packing is commonly practiced in postoperative care after nose and sinus surgery, not only for haemostasis but also as internal stabilisation and synechia formation control. The aim of our study was to compare the pain level, adhessions and haemostatic properties of Stammberger sinus dressing (SSD) with Dissolvable Sinu-Knit (DSK) and routine nasal packing in latex gloves finge...

This paper introduces PAPA: Packed Arithmetic on a Prefix Adder, a new approach to parallel prefix adder design that supports a wide variety of packed arithmetic computations, including packed add and subtract with saturation, packed rounded average, and packed absolute difference. The approach consists of altering the prefix adder cell logic equations to take advantage of a previously unused “...
