Large-scale traffic flow simulation based on intelligent PSO [PDF]

MATEC Web of Conferences, 2022
With the rapid development of urban traffic, a large number of vehicles in cities not only bring convenience to people, but also bring a series of traffic problems, including traffic congestion and high traffic accident rates.

Large scale MD simulations of nucleation [PDF]

AIP Conference Proceedings, 2013
We present preliminary results from large scale molecular dynamics (MD) simulations of homogenous vapor to liquid nucleation. The simulations contain between one and eight billion Lennard-Jones atoms and were run for up to 56 million time-steps. The large particle numbers (over 104 times larger than previous simulations, see e.g.

Anatomy of Bs → VV decays and effects of next-to-leading order contributions in the perturbative QCD factorization approach

Nuclear Physics B, 2018
By employing the perturbative QCD (PQCD) factorization approach, we calculated the branching ratios, CP-violating asymmetries, the longitudinal and transverse polarization fractions and other physical observables of the thirteen charmless hadronic B¯s0 ...

Fast simulation of large‐scale growth models [PDF]

Random Structures & Algorithms, 2011
AbstractWe give an algorithm that computes the final state of certain growth models without computing all intermediate states. Our technique is based on a “least action principle” which characterizes the odometer function of the growth process. Starting from an approximation for the odometer, we successively correct under‐ and overestimates and ...

The production and decay of the top partner T in the left–right twin Higgs model at the ILC and CLIC

Nuclear Physics B, 2015
The left–right twin Higgs model (LRTHM) predicts the existence of the top partner T. In this work, we make a systematic investigation for the single and pair production of this top partner T through the processes: e+e−→tT¯+Tt¯ and TT¯, the neutral scalar

Large-scale simulations of fluctuating biological membranes [PDF]

The Journal of Chemical Physics, 2010
We present a simple, and physically motivated, coarse-grained model of a lipid bilayer, suited for micron scale computer simulations. Each ≈25 nm2 patch of bilayer is represented by a spherical particle. Mimicking forces of hydrophobic association, multiparticle interactions suppress the exposure of each sphere’s equator to its implicit solvent ...

Electronic cleansing in computed tomography colonography using AT layer identification with integration of gradient directional second derivative and material fraction model

BMC Medical Imaging, 2017
Background In computed tomography colonography images, electronic cleansing (EC) is applied to remove opacified residual materials, called fecal-tagging materials (FTM), using positive-contrast tagging agents and laxative to facilitate polyp detection ...

Anatomy of Bs → PP decays and effects of the next-to-leading order contributions in the perturbative QCD approach

Nuclear Physics B, 2019
By employing the perturbative QCD (PQCD) factorization approach, we made a systematic investigation for the CP-averaged branching ratios and the CP-violating asymmetries of the thirteen B¯s0→PP decays (here P=(π,K,η,η′)) with the inclusion of all ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Curvature-Influenced Electrocatalytic NRR Reactivity by Heme-like FeN₄-Site on Carbon Materials

Molecules
Two-dimensional carbon materials and their derivatives are widely applied as promising electrocatalysts and supports of single-atom sites. Theoretical investigations of 2D carbon materials are usually based on planar models, yet ignore local curvature ...
