BUQEYE guide to projection-based emulators in nuclear physics

چکیده

The BUQEYE collaboration (Bayesian Uncertainty Quantification: Errors in Your effective field theory) presents a pedagogical introduction to projection-based, reduced-order emulators for applications low-energy nuclear physics. term emulator refers here fast surrogate model capable of reliably approximating high-fidelity models. As the general tools employed by these are not yet well-known physics community, we discuss variational and Galerkin projection methods, emphasize benefits offline-online decompositions, explore how concepts lead bound scattering systems that enable accurate calculations using many different parameter sets. We also point future extensions physics, guided mature (order) reduction. All examples discussed more available as interactive, open-source Python code so practitioners can readily adapt projection-based their own work.

Virtual Wires: Overcoming Pin Limitations in FPGA-based Logic Emulators Jonathan Babb, Russell Tessier, and Anant Agarwal MIT Laboratory for Computer Science Cambridge, MA 02139 Existing FPGA-based logic emulators suffer from limited inter-chip communication bandwidth, resulting in low gate utilization (10 to U) percent). This resource imbalance increases the number of chips needed to emulate a...

Tests of Micro - Pattern Gaseous Detectors for Active 1 Target Time Projection Chambers in nuclear physics

9 Active target detection systems, where the gas used as the detection medium 10 is also a target for nuclear reactions, have been used for a wide variety of 11 nuclear physics applications since the eighties. Improvements in MPGD (Mi12 cro Pattern Gaseous Detectors) and in micro-electronics achieved in the last 13 decade permit the development of a new generation of active targets with 14 high...

Behnke has demonstrated that the "lean body mass," since it represents the active tissue of a person, is superior to reference standards hitherto proposed for the estimation of physiological functions such as the masses of various organs and tissues and the volumes of the different fluid compartments in the body. In the present article, which has been reprinted as a short ...
