, 2013 We confirm and expand on work by Chafin and Schaefer on hydrodynamic fluctuations in the unitary Fermi gas. Using the result for the equation of state from a recent MIT experiment, we derive lower bounds for \eta/n and \eta/s as a function of temperature.

Adjusted power estimates in monte carlo experiments [PDF]
Communications in Statistics - Simulation and Computation, 1994 Critical values and powers of competing tests are often evaluated through Monte Carlo simulations. Since the true levels of those tests are often very different, comparisons of the power estimates are not valid. We suggest that Monte Carlo estimates of critical values be used to create adjusted power estimates which are then comparable.

Quantum Monte Carlo calculations of nuclei with A 7 [PDF]
, 1997 We report quantum Monte Carlo calculations of ground and low-lying excited states for nuclei with A{le}7 using a realistic Hamiltonian containing the Argonne v{sub 18} two-nucleon and Urbana IX three-nucleon potentials.

International Journal of Adaptive Control and Signal Processing, EarlyView.This paper proposes two projector‐based Hopfield neural network (HNN) estimators for online, constrained parameter estimation under time‐varying data, additive disturbances, and slowly drifting physical parameters. The first is a constraint‐aware HNN that enforces linear equalities and inequalities (via slack neurons) and continuously tracks the ...

Monte Carlo localization algorithm based on particle swarm optimization
Automatika, 2019 In wireless sensor networks, Monte Carlo localization for mobile nodes has a large positioning error and slow convergence speed. To address the challenges of low sampling efficiency and particle impoverishment, a time sequence Monte Carlo localization ...

A Workflow to Accelerate Microstructure‐Sensitive Fatigue Life Predictions
Advanced Engineering Materials, EarlyView.This study introduces a workflow to accelerate predictions of microstructure‐sensitive fatigue life. Results from frameworks with varying levels of simplification are benchmarked against published reference results. The analysis reveals a trade‐off between accuracy and model complexity, offering researchers a practical guide for selecting the optimal ...

Continuous Sizing and Identification of Microplastics in Water
Sensors, 2023 The pollution of the environment with microplastics in general, and in particular, the contamination of our drinking water and other food items, has increasingly become the focus of public attention in recent years.

, 2006 We construct a quantum Monte Carlo algorithm for interacting fermions using the two-body density as the fundamental quantity. The central idea is mapping the interacting fermionic system onto an auxiliary system of interacting bosons. The correction term
