In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as, where u and v represent the horizontal and vertical velocity components,...

There has been renewed interest in developing polymer valves. Here, the objectives are to demonstrate the feasibility of modifying a commercial pulse duplicator to accommodate tri-leaflet geometries and to define a protocol to present polymer valve hydrodynamic data in comparison to native and prosthetic valve data collected under near-identical conditions.

Advancements in biomaterial technologies enable the development of three-dimensional multi-cell-type constructs. We have developed electrospinning protocols to produce three individual scaffolds to culture the main structural cells of the airway to provide a 3D in vitro model of the airway bronchiole wall.

An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions. These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Source: Alexander S Rattner, Department of Mechanical and Nuclear Engineering, The Pennsylvania State University, University Park, PA This experiment introduces the measurement and modeling of pressure losses in piping networks and internal flow systems. In such systems, frictional flow resistance from channel walls, fittings, and obstructions causes mechanical energy in the form of fluid pressure to be converted to heat. Engineering analyses are needed to size flow hardware to ensure...
FAQs
Each processing stream first learns a representation from its assigned information source rather than immediately collapsing all inputs together. The architecture then combines these representations through intermediate and final fusion layers. This arrangement preserves stream-specific structure while allowing the model to use relationships among feature types, temporal patterns, or sensory modalities when generating a common prediction or classification.
Separate streams allow the architecture to treat complementary aspects of neural data according to their distinct structure. One stream can represent a particular feature type, temporal pattern, or sensory modality without forcing it into the same initial representation as the others. Their later integration can therefore retain specialized information while supporting analysis of how the signals contribute jointly.
Intermediate fusion combines learned representations during processing, allowing information from the three streams to interact before the model reaches its output. Final fusion integrates the resulting representations for the shared prediction or classification task. Using both stages supports relationships that may emerge during processing as well as complementary information needed at the final decision point.
A single-stream approach has fewer opportunities to preserve distinctions among complementary signals before analysis. By maintaining three learned representations and then integrating them, the Tri-stream Network can model how distributed information relates across streams. This is relevant when neural phenomena depend on combined feature types, temporal patterns, or sensory modalities rather than on one signal alone.
A practical workflow assigns three complementary neural-data inputs to separate streams, allowing each stream to learn its own representation. The model then applies intermediate and final fusion before producing a shared prediction or classification. This setup can be adapted to the available measurements and research question, provided the selected streams represent meaningfully distinct information.
For neural-signal analysis, the architecture can combine multiple learned representations to support a shared decoding or classification task. In brain-state decoding, this provides a way to relate complementary measurements or signal characteristics within one model. The resulting analysis can help examine how distributed information contributes to neural states, perception, cognition, or behavior.
The framework is suited to questions about how information distributed across neural measurements or signal dimensions supports perception, cognition, and behavior. By integrating complementary streams, investigators can study whether combined information improves a shared prediction or classification outcome. It therefore provides computational context for examining interactions among neural signals rather than treating each source in isolation.
