aggregate

[ag′rəgāt]
Etymology: L, ad + gregare, to gather together
1 the total of a group of substances or components making up a mass or complex. Data on individual patients can be aggregated to allow conclusions about the patient population to be made.
2 See aggregation.

Aggregate

Epidemiology A group of persons who share one or more traits or characteristics without necessarily having had any direct social connection.
Examples All female doctors; all European cities with populations over 20,000; all coal miners.
Zoology A group of species within a genus, but not a subgenus; a group of subspecies, often written within brackets.

When mean serum leptin levels of PD patients were compared with platelet aggregation measurements in first test cell (C1), statistically significant difference was not detected for mean AUC, velocity and aggregation mean values (p values were 0.
P values of C1-C2, C1-C3 and C1-C4 for AUC and aggregation mean values were found 0.
When we divide PD patients, according to their serum leptin levels measured in the recent year as those above (n=16) and below (n=27) 25 ng/ml into two groups and compare their aggregation parameters with C1 we did not find increased platelet aggregation in higher serum leptin group (p=0,2 for AUC and aggregation, p=0,1 for velocity).
In our study, platelet aggregation was measured using Multiplate device capable of measuring the whole blood.
Malyszko et al, in their study investigating the relationship between plasma and peritoneal fluid leptin levels with platelet aggregation by using ristocetin and arachidonic acid as agonists, found a positive correlation between these parameters.
Differently, we searched in vitro effect of varying concentrations of human recombinant leptin on platelets activated with ADP in PD patients and we could not find a statistically significant difference for ADP activated platelet aggregation parameters in different leptin concentrations.
We substitute the time t for the aggregation count x for ease of understanding.
1, as the aggregation count increases, the communication cost decreases and the delay cost is increased.
In the basic approach, we present the core principle for optimizing the aggregation point.
3), we can derive the success probability of aggregation during the t waiting time via integral calculus (0 to t).
Also, we can derive the expected wait time E(t),which is the time the node waits until the first successful aggregation on the condition of occurrence.
So, we can calculate the total expected cost per packet of waiting for the first successful aggregation as follows:
