Directing a chaperone
E arly in development, the central nervous system originates from the neural plate, which folds on itself to form the neural tube. In the cranial region, this complex morphogenesis also requires forces generated in the epithelium and mesenchyme that surround the neural tissue. The edges of the neural plate, for example, are initially pushed upwards by the underlying cranial mesenchyme (CM), whi...
متن کاملDirecting a Portfolio with Learning
Algorithm portfolios are one approach designed to harness algorithm bias to increase robustness across a range of problems. We conjecture that learning based on the previous performance of a suite of planning systems can direct a portfolio strategy at each of three stages: selecting which planners to run; ranking the order to run the selected planners; and allocating computational time to them....
متن کاملDirecting thrombin.
Following initiation of coagulation as part of the hemostatic response to injury, thrombin is generated from its inactive precursor prothrombin by factor Xa as part of the prothrombinase complex. Thrombin then has multiple roles. The way in which thrombin interacts with its many substrates has been carefully scrutinized in the past decades, but until recently there has been little consideration...

The purpose of this study was to investigate how nursing students manage their time despite the academic difficulties and obstacles. Methods: This qualitative study was carried out through grounded theory met...
متن کاملA Procedural Interface for Program Directing
Debugging and performance measurement tools are becoming more important in the development and maintenance of increasingly complex software. These tools belong to a class of programs, called directors. Directors are programs that monitor and control other programs. Through monitoring, directors analyze program execution at runtime. Monitoring provides tracing primitives as well as access to pro...
