It is typically used to describe a pattern of continuous growth or progress over a period of time. Example: The company's profits have been systematically increasing from $1 million to $5 million over the past five years.
Intervals were systematically increased from 3 min 30 s to 15 min in the training setting.
B2O3 content was systematically increased from 5 to 30 mol%, at the expense of P2O5, in the chemical composition of these glasses.
NaCl was chosen as representative 1 1 electrolytic solution and the electrolytic concentration was systematically increased from 0.001 M up to 0.1 M (the limit of the electrokinetic analyser).
A sensitivity analysis was performed where the hybridization threshold was systematically increased from 0 to 100.
In addition, the length of l-alanine crystals was systematically increased from ∼380 to ∼2000 μm using the MA-MAEC technique.
ICG concentration of the ICG HSA complex was systematically increased from 10too 500 μM to explore the counteracting effects of NIR fluorophore quenching at the injection site and NIR fluorophore dilution within the lymphatic channels.
The use of the metal-assisted and microwave accelerated evaporative crystallization (MA-MAEC) technique afforded the growth of l-alanine crystals with different morphologies up to ∼10-fold faster than those grown at room temperature, where the length of l-alanine crystals was systematically increased from ∼380 to ∼2000 μm.
The depth of hypocenters is systematically increasing westward from Anomalies 3 to 1 along the subducting Pacific plate (Fig. 7(b)).
In progressive-ratio schedules, N is systematically increased, usually from one reinforcer to the next (Hodos, 1961; Stafford and Branch, 1998), but sometimes after batches of two or more reinforcers (Baunez et al., 2002; Randall et al., 2012) or between successive sessions (Griffiths et al., 1978; Czachowski and Samson, 1999).
