Multicanonical sequential Monte Carlo sampler for uncertainty quantification

Robert Millar, Hui Li, Jinglai Li

Summary: In many engineering systems, the performance or reliability is characterized by a scalar variable. The distribution of this variable is important for uncertainty quantification in various applications. Standard Monte Carlo simulations are often used but struggle to efficiently estimate the tail of the distribution. The Multicanonical Monte Carlo method provides an adaptive importance sampling scheme, where samples are drawn from a nonstandard importance sampling distribution using Markov chain Monte Carlo (MCMC). However, MCMC is inherently serial and difficult to parallelize. In this paper, we propose a new approach that uses the Sequential Monte Carlo sampler for parallel implementation and demonstrate its competitive performance with mathematical and practical examples.

A method for evaluation of aerodynamic lift and drag based on statistical mechanics

Haibing Peng

Summary: Despite the widespread use of Navier-Stokes equations in computational-fluid-dynamics (CFD), there are still unanswered questions due to the absence of considering the statistical nature of discrete air molecules. In this study, we propose a statistical mechanics-based approach called the volume-element method, which allows for the numerical evaluation of aerodynamic lift and drag. We obtained pressure and friction values as a function of the angle of attack for flat-plate airfoils, and this method can be directly applied to convex-shape airfoils and combined with Monte Carlo simulations for concave-shape airfoils. This approach not only has implications for aerodynamic applications, but also opens up possibilities for further applications in Boson or Fermi gases.

Quantum Phase Transition in a Quantum Ising Chain at Nonzero Temperatures

K. L. Zhang, Z. Song

Summary: The study reveals that applying a nonlocal non-Hermitian perturbation to an Ising chain merges the topological Kramer-like degeneracy in the ferromagnetic phase, with distinct dynamic responses for different quantum phases. The phase diagram at zero temperature is completely preserved at finite temperatures.

Deep-learning-based 3D blood flow reconstruction in transmissive laser speckle imaging

Ruoyu Chen, Shanbao Tong, Peng Miao

Summary: This study proposes a deep-learning-based strategy for high spatiotemporal resolution three-dimensional (3D) reconstruction from a single transilluminated laser speckle contrast image, providing more structural and functional details without multifocus two-dimensional (2D) imaging or 3D optical imaging with point/line scanning. The method utilizes convolution of vessel masks with depth-dependent point spread functions (PSF) to generate a large training dataset, and employs UNet and ResNet for deblurring and depth estimation. The blood flow in the reconstructed 3D vessels is estimated by a depth-dependent contrast model. The proposed method achieves high-fidelity structural reconstruction with a depth-independent estimation of blood flow, and is suitable for real-time monitoring of thick tissue and the diagnosis of vascular diseases.

Brownian bridges for stochastic chemical processes-An approximation method based on the asymptotic behavior of the backward Fokker-Planck equation

Shiyan Wang, Anirudh Venkatesh, Doraiswami Ramkrishna, Vivek Narsimhan

Summary: A Brownian bridge is a continuous random walk guided by an effective drift to control the endpoint of a stochastic process. While widely applicable in chemical science, the main limitation is the difficulty in determining the effective drift and solving the complex Backward Fokker-Planck equation.

Post-reaction internal energy distributions of quantum-kinetics model for simulating chemical reactions of polyatomic molecules

Da Gao, Bijiao He, Chenggeng Wu, Guobiao Cai, Lihui Liu

Summary: This study compares the energy distribution of the chemical reaction C O-2 + O ? CO + O-2 using the Larsen-Borgnakke (L-B) and Q-K methods, and finds that only the Q-K method achieves detailed balance. The study also indicates that detailed balance is reached only when the collision temperature is used to adjust the activation energy, rather than the translational temperature.

Predicting COVID-19 Transmission to Inform the Management of Mass Events: Model-Based Approach

Claire Donnat, Freddy Bunbury, Jack Kreindler, David Liu, Filippos T. Filippidis, Tonu Esko, Austen El-Osta, Matthew Harris

Summary: This paper aimed to provide informative risk metrics for live public events by evaluating the number of infectious cases, pre-event screening efficiency, and transmission dynamics through Monte Carlo simulations. The results indicate that the risk of events depends on factors such as prevalence, mask wearing, and event duration, with significant increases in transmission events in high-risk scenarios.

Robust inference in single firm/single event analyses

Ralf Elsas, Daniela Stephanie Schoch

Summary: Single firm/single event (SFSE) studies are relevant in corporate finance. Inference on abnormal returns in this context faces the problem of heteroscedasticity. Robust inference in SFSE setting is analyzed using Monte Carlo and resampling experiments. A unique specification test for structural breaks is developed, and the most robust inference is obtained by using intraday data and a multiplicative component GARCH estimator.

Summary: Using data collected with the BESIII detector at the BEPCII storage ring, a precise measurement of the e(+)e(-) -> pi(+)pi(-) J/psi Born cross section is performed. Two structures, identified as the Y(4220) and Y(4320) states, are observed, and their masses and widths are determined. Additionally, an additional resonance is possibly indicated by a small enhancement around 4.5 GeV in the spectrum.

Learning trivializing flows

D. Albandea, L. Del Debbio, P. Hernandez, R. Kenway, J. MarshRossney, A. Ramos

Summary: This work studies a modified HMC algorithm based on normalizing flows, which reduces autocorrelations by sampling from a simplified action. The algorithm is tested in a 2D f(4) theory, showing reduced autocorrelation times compared to traditional HMC, and the training can be done at small unphysical volumes and used in physical conditions. The scaling of the algorithm towards the continuum limit is also investigated under different assumptions on the network architecture.

Skipping the Replica Exchange Ladder with Normalizing Flows

Michele Invernizzi, Andreas Kraemer, Cecilia Clementi, Frank Noe

Summary: In this paper, a method named Learned Replica Exchange (LREX) is proposed, which combines replica exchange with normalizing flows to efficiently sample rare events. By training a normalizing flow to map the configurations of the fastest-mixing replica into configurations of the target distribution, LREX enables direct exchanges between the two without simulating intermediate replicas, thus significantly reducing computational cost. The proposed method also offers advantages compared to using normalizing flows directly for sampling the target distribution.

Summary: This study reports the design of vertical matrix perovskite X-ray detectors for multi-energy detection. The detectors can accurately reconstruct incident X-ray spectra and produce a set of images with density-graded information under single exposure. It can also locate the position of substances with different densities.

Spin and polarization analysis of the Zcs state

Hong Chen, Qi Huang, Rong-Gang Ping

Summary: A polarization analysis is conducted for the recent observation of the Z(cs) exotic state, aiming to measure its spin quantum number in the future. The transfer of polarization to the Z(cs) state and the angular distribution of its decay are investigated. Observable quantities are suggested for determining the spin parity quantum numbers, and Monte-Carlo events are used to demonstrate the manifestation of different Z(cs) spin scenarios.
