, 2015 Approximate Bayesian computation (ABC) is a powerful and elegant framework for performing inference in simulation-based models. However, due to the difficulty in scaling likelihood estimates, ABC remains useful for relatively low-dimensional problems. We introduce Hamiltonian ABC (HABC), a set of likelihood-free algorithms that apply recent advances in

Proton Acceleration with Relativistic Electromagnetic Shock
Advanced Science, EarlyView.New Ion Acceleration Mechanism! A novel cosmic‐ray proton acceleration mechanism is proposed, where relativistic electromagnetic shocks accelerate protons transversely. Hamiltonian analysis yields a scaling law linking the proton energy to the minimum longitudinal thickness of the shock.

Advanced Science, EarlyView.Chiral nano‐inorganics, free of organic chiral ligands, provide a novel platform to direct symmetry breaking in molecular systems, through inorganic‐to‐organic chirality transfer via enantiospecific inorganic–organic interactions, circularly polarized light, and electron spin‐driven enantiopreferential reactions governed by chiral‐induced spin ...

Browder spectra of closed upper triangular operator matrices
AIMS MathematicsLet $ T_{B} = \left[\begin{array}{ll} A & B \\ 0 & D \end{array}\right] $ be an unbounded upper operator matrix with diagonal domain, acting in $ \mathcal H \oplus\mathcal K $, where $ \mathcal H $ and $ \mathcal K $ are Hilbert spaces.

Advanced Science, EarlyView.This study presents a microwave‐activated composite integrating expanded graphite with α‐MnO2 nanowires, engineered to synergistically optimize dielectric and magnetic properties. The innovative microwave‐driven process enables rapid structural transformation, yielding ultrathin, scalable electromagnetic wave‐absorbing films.

Effective Hamiltonian of Electroweak Penguin for Hadronic b Quark Decays [PDF]
Journal of Sciences, Islamic Republic of Iran, 2009 In this research we work with the effective Hamiltonian and the quark model. We investigate the decay rates of matter-antimatter of quark. We describe the effective Hamiltonian theory and apply this theory to the calculation of current-current ( ), QCD
