Aggregation in Anurida maritima
… internal circartidal clock is used to regulate aggregation patterns during high tide. The mechanism underlying the circatidal clock is not fully understood, although it is possible that zeitgebers influence the clock. 1.2 Petri Dish Observations Previous studies have shown that the circatidal …

Aggregation in temporal databases
… databases. We introduce a taxonomy of temporal aggregation, based on a study of all major temporal query languages containing aggregates. The taxonomy categorizes the expressiveness and functionality of temporal aggregation. Based on this taxonomy, we introduce extensions to TSQL2 for temporal …

Kinetics of Peptide Aggregation
The most thermodynamically stable biological structure is the cross-beta secondary structure of the "amyloid"or "prion". As a testament to its stability, the amyloid occurs naturally in 2 rare instances: as a mechanism to protect or destroy life. Pathogenic amyloids are the signature of …

Characterization of Oxidized Tau Protein Aggregation and Inhibition of Tau Aggregation via MAP2
… modifications are a modulator of Tau aggregation in vivo. Previous studies inferred that oxidation may be a post translational modification that plays a role in the amyloidogenesis of Tau. However, conflicting reports left some uncertainty, stating that intramolecular oxidized Tau …

Insights into the structure and aggregation of lens crystallins and other aggregation-prone proteins
… The destabilization, partial unfolding, and aggregation of lens crystallin proteins cause the loss of lens transparency (opacification) and cataract formation. Numerous congenital mutations and age-related changes to the long-lived alpha-, beta- and gamma-crystallins are associated with …

Computational modeling of melanin aggregation
… DHICA-eumelanins were investigated, showing aggregation of uncharged DHICA-eumelanins and a few charged DHICA-eumelanins present on the surface of the aggregate and binding to the K+ counteri- ons. Overall, these findings contribute to a better understanding of the structural properties of …

Multidimensional aggregation in OLAP systems
… queries require extensive computation based on aggregation along many dimensions and hierarchies. The time required to process these queries has traditionally prevented the interactive analysis of large databases and in order to accelerate query-response time, precomputed results are often …

Order, disorder, and protein aggregation
Protein aggregation underlies a number of human diseases. Most notably, it occurs widely in neurodegenerative diseases, including Alzheimer's and Parkinson's. At the molecular level, neurotoxicity is thought to originate from toxic gains of function in multimeric aggregates of proteins that are …

Dynamic Aggregation of Grid-tied Inverters
… inverter model. Furthermore, a network-cognizant aggregation approach for distribution networks comprising grid-tied inverters is developed. Inverters are clustered based on effective impedances to an infinite bus (modeling the transmission-distribution boundary) and for each cluster, the …

Mathematical aggregation of probabilistic expert judgements
Mathematical aggregation of the probabilistic expert’s judgements in a structured expertjudgement analysis is said to be relevant and critical. Due to absence of data, the judgementsof the experts are used to perform forecasting and risk analysis. However, there is a gapin the literature where …

User-centric framework for device aggregation
… the environment in order to form an appropriate aggregation. Even a small number of devices can be aggregated in many ways to perform a particular task effectively. This problem is more severe when the user is in an environment with unfamiliar devices, when a large number of devices are …
