The phrase "a decrease in the sum" is correct and usable in written English.
It can be used when discussing a reduction in a total amount, often in contexts like finance, mathematics, or statistics.
Example: "The recent budget cuts resulted in a decrease in the sum allocated for community programs."
Alternatives: "a reduction in the total" or "a decline in the amount".
Both CV and EIS results showed a decrease in the sum of transfer coefficients and an increase in the electron transfer resistance, which indicate that the adsorption film is a non-conductive film.
It is clear that the increase in the total sum rate, R s +R p, is accompanied by a decrease in the sum primary rate R p. Hence, the sum primary rate has to be protected above a minimum limit.
The increased queue status of the delay-sensitive flows is periodically monitored by the proxy, resulting in rate adaptation for the SVC flows at the proxy, which causes a decrease in the sum MOS for delay-sensitive flows.
Clinical responses were evaluated according to RECIST criteria[15] with the additional criterion of Minor response, which is considered a decrease in the sum of target lesion diameters between 20 30%, insufficient to qualify for Partial response (30% decrease in the sum of the diameters).
Minor response was defined as a decrease in the sum of the products of diameters of ⩾25%and<50%0% for ⩾8 weeks.
In patients with a decrease in the sum of MIBG IR, there was an improvement in symptoms related to excessive catecholamine release and in arterial blood pressure.
In this case, it sequentially processes each observation and reassigns it to another cluster if doing so results in a decrease in the total within-cluster sums of squares (referring to [ 37] for the details).
The primary endpoint was the response (defined as a decrease in the HAMD-17 sum score of at least 50%) in physicians' assessment after 6 months of treatment.
There was no significant difference in response (defined as a decrease in the HAMD-17 sum score of at least 50%) after six months of treatment (50% vs. 42%, p = 0.961, all analyses adjusted for age) and after 12 months of treatment (83% vs. 54%, p = 0.282) between groups.
At all intensities, the best data fit was obtained when the model incorporated a slow component (R = 0.94, 0.92, and 0.90 for 95, 100, and 105% of vVO2max intensity) as opposed to a single exponential model, once a significant decrease in the sum of squared residuals occurred (the criterion measure used for each model).
A partial response (PR) is at least a 30% decrease in the sum of the longest diameter of target lesions, taking as reference the baseline sum longest diameter.
