Advances of the counterflow pipeline microarchitecture
Proceedings Third International Symposium on High-Performance Computer Architecture, 2002The counterflow pipeline concept was originated by R.F. Sproull et al. (1994) to demonstrate the concept of asynchronous circuits. This architecture provides better throughput via clocking and data locality within the pipeline. We have taken these ideas and reformulated them into a scalable architecture that has the same locality for clocking and data,

Non-stalling counterflow architecture
Proceedings 1998 Fourth International Symposium on High-Performance Computer Architecture, 1998The counterflow pipeline concept was originated by Sproull et al.(1994) to demonstrate the concept of asynchronous circuits. This architecture relies on distributed decision making and localized clocking and data movement. We have taken these ideas and reformulated them into a substantially faster more scalable architecture that has the same ...

Enrichment of Corticotropes by Counterflow Centrifugation*
Endocrinology, 1988Anterior pituitary corticotropes represent only 9-10% of the mixed pituitary cell population. However, their small size precludes their enrichment because they cannot be separated from the more abundant PRL and GH cells. They can be induced to enlarge by adrenalectomy, and this report describes the separation of larger CRH-responsive corticotropes from

The counterflow pipeline processor architecture
IEEE Design & Test of Computers, 1994The counterflow pipeline processor architecture (CFPP) is a proposal for a family of microarchitectures for RISC processors. The architecture derives its name from its fundamental feature, namely that instructions and results flow in opposite directions within a pipeline and interact as they pass.

Counterflow of galactosides in Escherichia coli
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1970Abstract Counterflow of β-galactosides in metabolically poisoned cells of Escherichia coli was systematically examined. In one type of experiment (“entrance counterflow”), azide-treated cells were preloaded with a galactoside, cells separated from the medium and finally resuspended in thio[ 14 C]methyl-β- d -galactopyranoside ([ 14 C]TMG).

Development of a swirling double counterflow
Physical Review E, 2011This numerical study of an axisymmetric motion of a viscous incompressible fluid in an elongated cylindrical container explains how a swirling inflow develops the global meridional circulation and two U-shaped throughflows (TFs). For moderate values of the Reynolds (Re) number, there is a single U-shaped TF: The fluid moves from the peripheral annular ...

Review of predictive models for the design of counterflow vortex tubes working with perfect gas
International journal of thermal sciences, 2019This review will focus on perfect gas models developed to predict the performances of counterflow vortex tubes. It includes empirical and thermodynamics models, models of heat exchangers, models based on a pressure gradient, models based on the momentum ...

Counterflow isotachophoresis in a monolithic column
Journal of Separation Science, 2014This study describes stationary counterflow isotachophoresis (ITP) in a poly(acrylamide‐co‐N,N′‐methylenebisacrylamide) monolithic column as a means for improving ITP processing capacity and reducing dispersion. The flow profile in the monolith was predicted using COMSOL's Brinkman Equation application mode, which revealed that the flow profile was ...

Counterflow spray combustion modeling
Combustion and Flame, 1989A fuel spray planar counterflow flame has been modeled by means of a low-Mach-number boundary layer approach. The model considers density variations and full coupling between the two phases by means of a hybrid Eulerian-Lagrangian formulation, with droplet drag and vaporization.

Development of colliding swirling counterflows
Physical Review E, 2011This numerical study of the axisymmetric motion of a viscous incompressible fluid in an elongated cylindrical container explains how colliding counterflows develop. Two swirling flows enter the container through peripheral inlets and leave it through central exhausts symmetrically from both ends.
