Identification Of A 2-stage Platelet Aggregation

We have demonstrated that the dynamics of this 2-stage aggregation process are critically influenced by 3 variables, including high shear stress, platelet surface density, and matrix reactivity, with the 2 former variables regulating reversible aggregate formation and the latter regulating the transition to stable aggregation ...

2020-4-7The aggregation pipeline provides an alternative to map-reduce and may be the preferred solution for aggregation tasks where the complexity of map-reduce may be unwarranted. Aggregation pipeline have some limitations on value types and result size. See for details on limits and restrictions on the aggregation pipeline.

2020-7-31Aggregations operations process data records and return computed results. Aggregation operations group values from multiple documents together, and can perform a variety of operations on the grouped data to return a single result. RESTHeart manages aggregation operations both aggregation pipelines and map reduce functions are supported.

Aggregation Of Biologically Important Peptides And ...

Several studies have shown that varying concentrations of Zn 2 have different effects on hIAPP aggregation and the different stages of the aggregation process. At high concentrations 10 mM and in the early stages of aggregation 40 min, Zn 2 promote the formation of large Zn 2 amylin aggregates.

The Kinetics Of The Granulation Process Right From The ...

2009-1-31The aggregation kinetics of the granulation process can be represented by only two parameters 0, the aggregation rate constant, and C, the critical binder volume fraction required for coalescence. The model can work even from the early stages of the process.

Mongodb Aggregation Framework Stages And

2018-8-21In this whitepaper, we deep-dive into MongoDBs Aggregation Framework and look into the different stages of the Aggregation Pipeline. We also look at how we make use of these stages in an aggregation process and then look at the operators that can assist in the analysis process

Early Stages Of Aggregation Of Engineered -synuclein ...

The rate of pairwise aggregation between different species was then monitored using dual-color fluorescence cross-correlation spectroscopy, measuring the extent of association between species labelled with different dyes at various time points during the early aggregation process. The aggregation rate and extent increased with tandem oligomer size.

Relationship Of Turbidity To The Stages Of Platelet ...

The process of platelet aggregation as detected by turbidity changes in the platelet aggregometer was studied relative to light scattering by large particles. For latex beads a plot of light scattering intensityunit mass versus particle size gave increased light scattering intensity for small particle sizes but decreased scattering at large ...

2016-9-15aggregation. It is also involved in the second wave of aggregation, as well as ADP release from platelet granules 5. A compound that inhibits ADP activated aggregation would halt the whole aggregation process, rather than just the beginning or end. In the past, platelet aggregation was measured by a machine called a platelet aggregometer.

Monitoring Early-stage Protein Aggregation By An ...

2019-5-26Highly ordered protein aggregates, termed amyloid fibrils, are associated with a broad range of diseases, many of which are neurodegenerative, for example, Alzheimers and Parkinsons. The transition from soluble, functional protein into insoluble amyloid fibril occurs via a complex process involving the initial generation of highly dynamic early stage aggregates or prefibrillar species.

Mongodb Aggregation Stages Of Aggregation

Aggregation process in MongoDB is modeled on the concept of data processing pipelines. Multiple documents enter the pipeline and then these documents are being transformed into aggregated results. The operations being performed during pipeline include filter and document transformation in which they operate like queries and modify the form of ...

Molecular Dynamics Study Of The Aggregation

2019-5-26The aggregation was found to be a pointlineplane process. Five forces were involved during the process van der Waals attraction, electrostatic interaction, hydrogen-bond interaction, stacking, and the collision of water molecules. The dominant forces were different in the three stages.

2. Observations and results. A set of spherical magnets of diameter a5 mm, mass m0.50 g is assembled in a necklace of N99 beads necklaces of N50 and N200 beads are also used.Two different sets of spheres are used with a magnetic force between the spheres Fa4.6 N or Fa3.9 N within less than 5 when the spheres are in contact.The necklace is positioned on a cone with an

Mongodb Manual 3.4

2020-4-7Aggregation Pipeline MongoDBs aggregation framework is modeled on the concept of data processing pipelines. Documents enter a multi-stage pipeline that transforms the documents into an aggregated result. The most basic pipeline stages provide filters that operate like queries and document transformations that modify the form of the output document.

Inertial And Slow Coherency Aggregation Algorithms For

2012-4-14Based on this analysis, we obtain an optimum aggregation where slow coherency aggregation is performed on areas 5, 6 and 11, and inertial aggregation is performed on areas 4, 7, 9 and 15. The Medway disturbance simulation of this optimum aggregate is shown in Figures 5 and 6.

2020-7-30In addition, pipeline stages can use operators for tasks such as calculating the average or concatenating a string. The pipeline provides efficient data aggregation using native operations within MongoDB, and is the preferred method for data aggregation in MongoDB. The aggregation pipeline can operate on a sharded collection.
