The phrase "as a positive pattern" is correct and usable in written English.
It can be used when discussing a recurring or favorable trend or behavior in a specific context.
Example: "The data shows that the team's performance has improved consistently, indicating a positive pattern in their work ethic."
Alternatives: "as a favorable trend" or "as a beneficial model".
As in the rat study, an operant procedure using both auditory and visual stimuli was employed to train the participants on a negative and a positive pattern as well as an incomplete negative or positive pattern.
A positive pattern can be interpreted as a cluster of stroke patients defined by some limitation imposed on the intensity of a few (in this case, two) peaks.
Immunostaining was scored as positive (pattern A and B) or negative (pattern C and D) based on the staining intensity (strong vs weak/negative) and immunoreactive patterns (diffuse vs focal).
In reality, the unstable slope cases (with landslides) are recognized as positive pattern, while stable slope cases (without landslides) are recognized as negative pattern.
FLC treatment, used as a positive control, showed a pattern of clearance comparable to that induced by terpinen-4-ol.
Lesions were categorised according to p16INK4a expression as (a) positive for a diffuse pattern of nuclear and/or cytoplasmic p16INK4a expression, beginning in the basal or parabasal layer and variably reaching intermediate and superficial cell layers, in analogy to squamous epithelial lesions at the uterine cervix (Klaes et al, 2001) and (b) negative for a diffuse p16INK4a expression.
Finally, instead of recording as a positive prediction, all the patterns that satisfy at least one rule, only the test examples with the top scores can be picked as positive predictions.
Therefore we regarded a dot-like granular staining pattern as a positive finding together with the coexistence of other luminal or equivocal staining patterns.
In fact, rats trained to choose a positive column pattern over a negative row pattern, not only preferred a less familiar vertical grating over a the training-positive column pattern (as originally shown by Kreschevsky), but also preferred the more familiar training-negative row pattern over a continuous horizontal grating.
The most common convention is to consider the left-hand, or "S" pattern (as viewed from the bark side) as a positive angle and right-hand "Z" pattern as negative (Harris, 1989) and this was adopted for this study.
