The phrase "a larger contribution of" is correct and usable in written English.
It can be used when discussing the extent or amount of something that is being contributed, often in a quantitative or qualitative context.
Example: "The study found that a larger contribution of renewable energy sources is necessary to combat climate change."
Alternatives: "an increased contribution of" or "a greater input of".
A larger contribution of G (62.3%) than Y (7.2%) and G × Y (27.9%) factors was found for the DMA concentration, indicating that the differences in grain DMA mostly depend on genotype.
Thus, the observed inclination shifts around excursions, shallower in the Okhotsk Sea and deeper toward negative in the western equatorial Pacific, may be explained by a larger contribution of the SCOR field when the GAD was weak.
The mean particle size of Au is about 3.5 nm while that of Pd is 1.5 nm (although the Pd particle size distribution was asymmetric at the low size indicating a larger contribution of small particles <1 nm); there was negligible number of Pd particles above 2 nm.
Both the Okhotsk Sea and western equatorial Pacific are within a region of outward directed flux in the persistent non-axial-dipole (NAD) field, and the synchronous inclination shifts may have been caused by a larger contribution of the NAD field when the GAD was weaker.
The synchronous inclination shifts associated with decreased paleointensity may be explained by a larger contribution of the SCOR field proposed by Hoffman and Singer (2008) when the GAD was weaker; both the Okhotsk Sea and western equatorial Pacific are within a region of outward directed flux in the persistent NAD field.
Whites also exhibit a larger contribution of high-RMI chronic respiratory diseases.
A large contribution of preaxial mesenchymal cells contributing to digit 1/distal carpal 1 are visible in these sections as well as the development of an independent Lateral Centrale and Intermedium at an older stage.
The gaseous flame base is essentially composed of an edge flame, with a large contribution of partially premixed combustion.
Noise from shooting ranges is characterized by high levels of impulse noise with a large contribution of low frequencies.
A small fin pitch and large louver angle cause a strong flow deflection and thus a large contribution of the louvers.
