You can use it when referring to an increase that has been driven by one or more factors. For example, "The company's profits were largely increased by higher sales of our new product."
Disassembly of the CA layer showed hysteresis and appears to proceed only after large enough defects (nucleation points) are formed in the lattice, whose number is largely increased by inducing materials fatigue that depends on mechanical load and its frequency.
However, the computational cost is largely increased by employing the interval type-2 fuzzy set.
The proton conductivity of the composite electrolytes was largely increased by introduction of Tz, particularly in the low temperature region.
This is largely increased by the need of data forwarding along the path, especially for nodes which are located near the BS.
Commercial SiO2 nanoparticles are suspended in an acid-catalysed SiO2 sol, whose stability is largely increased by adding tetramethylammonium hydroxide (TMAH) up to pH 6. Coatings are formed by dipping and by EPD on AISI 304 stainless steel substrates.
The proton conductivity of the composites was largely increased by introduction of Azoles, particularly in the lower temperature region than a superprotic phase-transition temperature of CHS and melting points of Azoles.
Another consequence of boron doping is the largely increased roughness factor revealed by atomic force microscopy (AFM) imaging.
The tensile strength, tensile modules and impact strength were found largely increase by means of either shear stress or compatibilizer.
The efficiency of the cold stage can largely be increased by precooling.
Season‑ticket sales were up too – this season all 35,000 have sold and "partnership income", largely sponsorship, has increased by almost 400% to £32.4m.
The population of blacks grew by 12 percent, and the aging white population was largely flat, increasing by less than 1 percent.
