After adjustment for age, gender, number of procedures and secondary diagnoses, longer hospital admissions and higher costs characterised surgical DRGs, with ≥10% of patients given blood or blood constituent transfusions.

Economic modelling weighs costs against characterised effects or predicted benefits in order to determine the most cost-efficient strategy but has traditionally used static models of disease not suitable for elimination.
In particular, the solution for decreasing battery costs is characterised by this behaviour.
Costs were characterised by a gamma distribution with alpha and beta parameters defined by the means and standard deviations of the costs.
Costs were characterised by a γ distribution with α and β parameters defined by the means and SDs of the costs.
As in previous work, this is a low cost, compact system characterised by a low processing power.
A permanent task of the electronic industry is to find methods in order to reduce production costs which are characterised by higher mass-production output.
It is also notable that as a proportion of total costs, the enzymatic process is characterised by a large cost of chemicals (15%), two-thirds of which can be attributed to the cost of enzymes alone.
As a result, we identify a 'hockey-stick'-shaped cost curve that is characterised by strong cost reductions at high density values which level out at around 1 to 1.5 plants per km2.
