The phrase "a power set of" is correct and usable in written English.
It is typically used in mathematical contexts to refer to the set of all subsets of a given set, including the empty set and the set itself.
Example: "The power set of {1, 2} is {{}, {1}, {2}, {1, 2}}."
Alternatives: "the set of all subsets of" or "a collection of subsets of".
σ -Algebra: The σ -algebra is a power set of Γ, denoted P.
Let R and P ( R ) be all subsets or a power set of R. Boolean algebra ℜ of the sets in P ( R ) has the following conditions [2, 3, 22, 23]: (I) A, B ∈ R ⇒ A ∪ B ∈ R, (II) A ∈ R ⇒ A c = R − A ∈ R, (III) A, B ∈ R ⇒ A ∩ B ∈ R, .
Post hoc tests showed a power setting of 0.5 J/80 Hz was significantly more efficient than low-power settings 0.2 J/50 Hz and 0.5 J/20 Hz (p < 0.05).
A power setting of 15 20 W is frequently used.
The cells were then resuspended in RLT buffer (QIAGEN, Inc., Valencia, CA) and lysed using a FastPrep FP101 bead beater (Bio 101) with 3×30 s bursts at a power setting of 6, followed by centrifugation.
Cells were disrupted by 5 7 pulses (30 sec each one) of sonication with a tapered ¼-microtip (6,5 mm) in a Branson digital sonifier 250 D, at a power setting of 30%, yielding genomic DNA fragments with a bulk size of 300 500 bp.
To insure cell-breakage, the supernatants were transferred to microtubes, placed in an ice/salt/alcohol slurry and probe sonicated using a GE 130 Ultrasonic Processor (Sonics and Materials, Inc) for 10 cycles of 15 sec cavitation at a power setting of 30 W with 2 min off.
In our experiments we used taps ranging from a power setting of 1 36.31.
Following excitation with a 488 nm laser at a power setting of 75 mW, all images were captured using a 40× objective.
The test was conducted on both the 2.4 GHz and 5 GHz direct sequencing frequency bandwidth at a power setting of 50 mW with two PC Notebooks.
A range of light doses, at a power setting of 100 mW, was delivered intravesically by a fibre optic inserted into the centre of the bladder via the urethra.
