Double parton distributions in the pion from lattice QCD

Journal of High Energy Physics, 2021
We perform a lattice study of double parton distributions in the pion, using the relationship between their Mellin moments and pion matrix elements of two local currents. A good statistical signal is obtained for almost all relevant Wick contractions. We

Small-world MCMC and convergence to multi-modal distributions: From slow mixing to fast mixing

, 2007
We compare convergence rates of Metropolis--Hastings chains to multi-modal target distributions when the proposal distributions can be of ``local'' and ``small world'' type.

Numerical analysis of temperature and current distributions in large-size intrinsic Josephson junctions with self-heating

AIP Advances, 2020
In this study, we focused on temperature and current distributions in voltage-state large-size intrinsic Josephson junction (IJJ) mesas with a self-heating effect.

The effect of local sources on aerosol particle number size distribution, concentrations and fluxes in Helsinki, Finland

Tellus: Series B, Chemical and Physical Meteorology, 2013
Three years of aerosol particle number concentrations (PNCs), size distributions and vertical particle fluxes measured at the semi-urban SMEAR III station in Helsinki, Finland, were studied.

Local environmental factors drive distributions of ecologically-contrasting mosquito species (Diptera: Culicidae)

Scientific Reports
Mosquitoes are important vectors of disease pathogens and multiple species are undergoing geographical shifts due to global changes. As such, there is a growing need for accurate distribution predictions.

Regional and local factors interact to shape colonization and extinction dynamics of invasive Hydrilla verticillata in a patchy landscape

Ecology and Evolution
Understanding the response of species to global change requires disentangling the drivers of their distributions across landscapes. Colonization and extinction processes, shaped by the interplay of landscape‐level and local patch‐level factors, are key ...

Densest Local Structures of Uniaxial Ellipsoids

Physical Review X, 2016
Connecting the collective behavior of disordered systems with local structure on the particle scale is an important challenge, for example, in granular and glassy systems.

Noise-robust proofs of quantum network nonlocality [PDF]

Quantum
Quantum networks allow for novel forms of quantum nonlocality. By exploiting the combination of entangled states and entangled measurements, strong nonlocal correlations can be generated across the entire network.

Surface roughness effects on plasma near a divertor plate and local impact angle

Nuclear Materials and Energy, 2017
The impact of rough surface topography on the electric potential and electric field is generally neglected due to the small scale of surface roughness compared to the width of the plasma sheath.
