The phrase "a null in the" is not correct and lacks clarity in written English.
It may be used in technical contexts, particularly in programming or data management, where "null" refers to a lack of value or a non-existent reference.
Example: "The function returned a null in the database query, indicating that no results were found."
Alternatives: "a void in the" or "an absence in the".
We see that, for increasing power levels, the transfer function tends to have, as expected, a null in the frequency range of interest.
When the two oscillations are 180° out of phase, we have an anti-symmetric mode whose electric field profile has a null in the gap.
Assuming the location of the jammer was known, a null in the antenna radiation pattern of the eNodeB could be generated to selectively block the interference.
Relaxing the null constraint for the ZF approach by treating a threshold of less than 20 dB as a null in the BF, still yields a higher backhaul rate of 759.3 kbps.
The self-interference caused by scatterer S 0, for example, in Fig. 1, could be avoided by creating a null in the direction of S 0. However, losing access to the scatterer could create a less-rich scattering environment, diminishing the spatial degrees-of-freedom of the uplink or downlink.
In a completely different perspective, as reprised in the following, a multisource algorithm for Direction Of Arrival (DOA) is presented in [12], where two maxima of a frequency-beamformer energy are obtained by putting a null in the DOA of the loudest source.
In the case of an ongoing uplink smart jamming attack, the cell would then go into a defense state, creating a null in reception and blocking the malicious interfering signal.
These variations in the primer annealing sites resulted in a null allele in the DNA tests causing the misdiagnosis of some heterozygous B. taurus × B.
A null mutation in the α1-subunit in the mouse oscillator (spd ot ) produces a strong neuromotor phenotype that causes death at ∼ 3 weeks postnatally (Buckwalter et al. 1994).
In mouse, a null mutation in the Aldh1a2 gene mimics the hindbrain phenotypes associated with full VAD, establishing Aldh1a2 as the main RA producing enzyme required in hindbrain development [29], [30], [50], [51].
(C and D ) No obvious changes in anti-Endos levels are seen in the mutant mouse MEF cells homozygous for a null mutation in the gene encoding the PP5 catalytic subunit (Yong et al., 2007 ) relative to control MEF cells.
