The phrase "a stable and efficient" is correct and usable in written English.
It can be used to describe something that is both reliable and effective, often in contexts related to systems, processes, or organizations.
Example: "The new software update has resulted in a stable and efficient performance, greatly improving user experience."
Alternatives: "a reliable and effective" or "a consistent and productive".
The non-doped electroluminescence device employing DPPP as emitting layer shows a stable and efficient violet emission with a maximum external quantum efficiency of 2.2% and a CIE coordinate of (0.16, 0.04), which is remarkable in reported violet devices.
Furthermore, it aims to improve the efficiency of carbon source use and ensure a stable and efficient process operation.
With the 1-position substituted analogue as the guest, the doped electroluminescence device showed a stable and efficient blue emission with the maximum luminance of 4306 cd/m2, the current efficiency of 1.15 cd/A, the external quantum efficiency of 0.97% and the CIE coordinate of (0.13, 0.06).
Even after Dr. Danby married and moved out, the two scientists spent free time developing a stable and efficient system.
Markets are waiting for a stable and efficient, laboriosa (in Italian, LABORIUS), Italy.
At the same time, he pacified California, establishing a stable and efficient civil government.
Thus simulation engineers need to "weakly", i.e., each problem is tackled separately, couple subproblems in an stable and efficient way.
Finally, we show that any direct mechanism for selecting a stable and constrained efficient matching is not strategy-proof.
ILRMA is theoretically equivalent to conventional MNMF only when the rank-1 spatial model (4) is assumed, which yields a stable and computationally efficient algorithm for ILRMA.
Valinomycin had a stable and less efficient effect on reducing ROS levels, while FCCP reduced ROS drastically after 30 minutes, reaching control levels after 24 hours.
In order to overcome these issues, in this paper, we propose a stable and energy-efficient routing technique.
