The phrase "ascending gradient" is correct and usable in written English.
It can be used in contexts related to mathematics, geography, or any field where a gradual increase in value or elevation is being described.
Example: "The trail follows an ascending gradient, making it a challenging hike for beginners."
Alternatives: "increasing slope" or "rising gradient".
The algorithm is named after its clustering mechanism of converging data points to their corresponding nearest local maxima of the data's density estimate along the ascending gradient direction.
As vacuum rate was increased to 10 ml/min/well the distribution improved and there were no significant differences in QCM position (despite at 0.5 L/min the trend suggesting there is an ascending gradient across the means).
Although a slight ascending gradient in deposited particulate mass was observed across the module at airflows 0.5 and 1.0 L/min, no statistical difference was observed between QCM positions at any of the airflows tested (0.5 L/min p-value 0.347, 1.0 L/min p-value 0.059, 2.0 L/min p-value 0.842, 4.0 L/min p-value 0.296 - Figure 3).
In the former, at 0.5 L/min diluting airflow and 10 ml/min/well vacuum, there appeared to be a significant ascending gradient in the mean values from positions 1 4 (Figure 4B) but no significant difference with a p-value of 0.451 (Table 2).
This was in contrast to the latter observed combination of 0.5 L/min diluting airflow and 50 ml/min/well vacuum, where there appeared to be much less of an ascending gradient across positions 1 4 (or at least less than 0.5 L/min diluting airflow and 10 ml/min/well vacuum) (Figure 4B) but there was a significant difference with a p-value of <0.01 (Table 2).
Bulk histones obtained by acid extraction of HEK cells were fractionated on a C8 column (220×4.6 mm Aquapore RP-300, Perkin-Elmer) using a linear ascending gradient of 0 100% solvent B (solvent A, 5% acetonitrile, 0.1% TFA; solvent B, 90% acetonitrile, 0.1% TFA) for >75 min at 1.0 mL/min on an AKTA FPLC system (Amersam Bioscience).
All scales showed ascending gradients in their mean scores across the response categories of the global item.
A slight ascending concentration gradient across the exposure module was observed at airflows 0.5 and 1.0 L/min.
Ascending alcohol gradient was used eventually to dehydrate the sections.
The specimens were fixed in neutral buffered formalin (Sigma Aldrich, St . Louis MO, USA) for 2 weeks and dehydrated in an ascending ethanol gradient (70%, 80 %, 90, and 100%).
These included wading deep water, ascending steep gradients with loose surfaces, dealing with high angles of departure and attack and soaking up a lot of punishment from wheel-swallowing potholes and big sharp rocks.
