Quantum ergodicity for quantum graphs without back-scattering [PDF]
, 2015 We give an estimate of the quantum variance for $d$-regular graphs quantised with boundary scattering matrices that prohibit back-scattering. For families of graphs that are expanders, with few short cycles, our estimate leads to quantum ergodicity for ...

The high-Q static scattering of 3-methyl pyridine/D2O mixtures without and with antagonistic salt [PDF]
EPJ Web of Conferences, 2023 Here we focus on the high-Q small-angle neutron scattering where we observed deviations from an ideal power law Q−2. From theory, this deviation Δ arises from the critical correlation-function exponent ηd in d dimensions.

A combinatorial approach to scattering diagrams [PDF]
, 2019 Scattering diagrams arose in the context of mirror symmetry, but a special class of scattering diagrams (the cluster scattering diagrams) were recently developed to prove key structural results on cluster algebras.

Transport of quantum noise through random media [PDF]
, 2004 We present an experimental study of the propagation of quantum noise in a multiple scattering random medium. Both static and dynamic scattering measurements are performed: the total transmission of noise is related to the mean free path for scattering ...

Journal of Physics G: Nuclear and Particle Physics, 2002 We discuss basic concepts and properties of diffractive phenomena in soft hadron collisions and in deep-inelastic scattering at low Bjorken-x. The paper is not a review of the rapidly developing field but presents an attempt to show in simple terms the close inter-relationship between the dynamics of high-energy hadronic and deep-inelastic diffraction.

Journal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022 Abstract Positron emission tomography with x‐ray computed tomography (PET/CT) is increasingly being utilized for radiation treatment planning (RTP). Accurate delivery of RT therefore depends on quality PET/CT data. This study covers quality control (QC) procedures required for PET/CT for diagnostic imaging and incremental QC required for RTP.
