The phrase "a second stage to" is correct and usable in written English.
It can be used when referring to an additional phase or level in a process or development.
Example: "The project will move into a second stage to evaluate the results of the initial testing."
Alternatives: "an additional phase of" or "a subsequent step in".
In a second stage, to begin Dec. 4, the Department of Homeland Security and the Justice Department will start six-week pilot projects in the immigration courts in Baltimore and Denver, in which teams of immigration agency lawyers will comb through the current dockets of those courts.
The project's long-term objectives include returning a launch vehicle first stage to the launch site in minutes and to return a second stage to the launch pad following orbital realignment with the launch site and atmospheric reentry in up to 24 hours.
Unless one assumes that relative position is implicitly encoded in patterns of activation within early topographic maps [3] one must hypothesise the existence of a second stage to the computation that either integrates information from low level filters [14], [15], [9], [16], [13] or endogenously generates 'virtual contours' between the stimulus elements [3], [16].
We propose fitting a full model in stage 1 to avoid confounding and to drop the least prominent effects in a second stage to increase the power.
Here, in a first stage, the subject is exposed to behaviorally meaningless CS1 CS2 associations and, in a second stage, to CS1 US (unconditioned stimulus) pairings.
The machine learning methods with the best performance were then used in a second stage to select a subset of important variables to develop models with performance comparable to that using the entire dataset.
But even that would have required the development of a third stage to get into space.
This setup is used in a first stage to determine regions of instability as a function of equivalence ratio and injection velocity.
This paper focuses on particle dynamics and gas-phase hydrodynamics in a rotating cone reactor as a first stage to obtain a basic understanding of the processes that govern the performance of this reactor.
Most initiatives about embedded sensing capabilities in computational systems lead to devise an ad hoc sensor platform, usually poorly reusable, as a first stage to prepare a data corpus or production prototype.
