The phrase "achieved by a weak" is not correct in written English as it appears to be incomplete or lacks context.
It could be used in a context discussing outcomes or results that are the result of a weak effort or method, but it needs additional information to clarify its meaning.
Example: "The results were achieved by a weak strategy that failed to consider all variables."
Alternatives: "accomplished through a weak" or "attained by a weak".
In the model, this can be achieved by a combination of weak selection and a large influx of new mutations: female preferences will become sufficiently variable if the costs of being choosy are small and if the distribution of new preference mutations is relatively broad.
This can be achieved by adding a weak base such as β-glycerophosphate (BGP) to an acidic solution of CS (Ruel-Gariepy et al. 2000; Tahrir et al. 2015).
This is achieved by introducing a weak discontinuity in the chloride concentration field for finite elements where the physical interface is present.
This is achieved by supplying a weak cation (NH4+) to excrete with Cl-.
For various theoretical reasons, the concept of gauge invariance seems fundamental, and many physicists believe that the final unification of the fundamental interactions (i.e., gravitational, electromagnetic, strong, and weak) will be achieved by a gauge theory.
Focusing is achieved by a single control.
Fluorescence excitation was achieved by a monochromator.
Both homogeneous and heterogeneous catalysis studies demonstrate that limiting acid base interactions is important and can be achieved by using weak acids (including surface silanols of heterogeneous catalysts) or using a rigid backbone between the acid and base.
Since Clegg et al. first fabricated SiC/C multilayer composites in 1990, multilayer ceramics have received much attention because of their improved properties achieved by designing weak interfaces.
The supramolecular complex gel was achieved by weak physical attractive forces, including intermolecular hydrophobic association, host-guest inclusion, and self-assembly between hydrophobic chains and wormlike micelles.
