The phrase "a core deficiency" is correct and usable in written English.
It can be used to describe a fundamental lack or shortcoming in a system, process, or individual.
Example: "The report highlighted a core deficiency in the company's training program that needs to be addressed."
Alternatives: "a fundamental flaw" or "a critical shortcoming."
According to the traditional neurocognitive view of ADHD, a core deficiency in cognitive control processes subserving the orchestration of thought and action with internal goals arises from neurodevelopmental anomalies in the prefrontal cortex [ 7].
While the traditional view of ADHD postulates a core deficiency in cognitive control processes, alternative dual-process models emphasize the dynamic interplay of bottom-up driven factors such as activation, arousal, alerting, motivation, reward and temporal processing with top-down cognitive control.
In addition, Gil et al. [ 39] suggested that SC requires a convergence of many neural networks and that the core deficiency in AD patients might be impaired SC, equated with the disability to maintain sequential and simultaneous "attention to life" [ 50, 51].
These issues are linked together by a set of core deficiencies that Obama is addressing with Race to the Top, an expanded GI Bill, and capped federal loan repayments.
WWE's core deficiencies are further masked by its high-paying, yet controversial, partnership with the Kingdom of Saudi Arabia.
If this complex is degraded, pyruvate is alternatively catalyzed into lac via lactate dehydrogenase, a core characteristic of pyruvate dehydrogenase complex deficiency (PDCD) syndrome [ 58].
BMAL1 (Brain and Muscle ARNT Like protein 1, also known as MOP3, ARNTL, and ARNT3), is a core component of the circadian system; deficiency of BMAL1 leads to the disturbance of circadian behavior and disruption of normal circadian patterns in gene expression in the brain and peripheral tissues such as the liver, kidney and muscles [ 8].
However, DDX6 deficiency was suppressed by disrupting LSM1, a core component of mRNA degradation machinery, suggesting that dysregulation of RNA processing underlies ISG activation in the DDX6 mutant.
Deficiency of the transcription factor BMAL1, a core component of the circadian clock, results in an accelerated aging phenotype in mice.
In CD71+Ter119+ erythroblasts, Mtf2 deficiency results in a global loss of promoter-proximal H3K27me3, aligning the function of Mtf2 in erythropoiesis more similar to a core PRC2 protein.
