Estimation of pollen counts from light scattering intensity when sampling multiple pollen taxa – establishment of an automated multi-taxa pollen counting estimation system (AME system) [PDF]
Atmospheric Measurement Techniques, 2021 Laser optics have long been used in pollen counting systems. To clarify the limitations and potential new applications of laser optics for automatic pollen counting and discrimination, we determined the light scattering patterns of various pollen types ...

Discrete Entanglement Distribution with Squeezed Light [PDF]
Physical Review Letters, 2004 We show how one can entangle distant atoms by using squeezed light. Entanglement is obtained in steady state, and can be increased by manipulating the atoms locally. We study the effects of imperfections, and show how to scale up the scheme to build a quantum network.

Simplifying the calculation of light scattering properties for black carbon fractal aggregates [PDF]
Atmospheric Chemistry and Physics, 2014 Black carbon fractal aggregates have complicated shapes that make the calculation of their optical properties particularly computationally expensive. Here, a method is presented to estimate fractal aggregate light scattering properties

Light quark distributions in the proton sea [PDF]
, 1999 We use the meson cloud model to calculate $\bar{d}(x) - \bar{u}(x)$ and $ \bar{d}(x)/\bar{u}(x)$ in the proton. We show that a modification of the symmetric, perturbative part of the light quark sea provides better agreement with the ratio $ \bar{d}(x ...

Light-front holographic ρ-meson distributions in the momentum space
Journal of High Energy Physics, 2021 We present the leading-twist quark transverse momentum-dependent parton distribution functions (TMDs) for the spin-1 target, such as the ρ-meson, in the light-front framework.

How extreme is extreme? An assessment of daily rainfall distribution tails [PDF]
Hydrology and Earth System Sciences, 2013 The upper part of a probability distribution, usually known as the tail, governs both the magnitude and the frequency of extreme events. The tail behaviour of all probability distributions may be, loosely speaking, categorized into two families: heavy ...

ρ meson GPDs and IPDs with a light-front constituent quark model [PDF]
EPJ Web of Conferences, 2019 We investigate the ρ meson unpolarized Generalized Parton Distributions based on a Light-Front Constituent Quark Model. Moreover, by employing a Gaussian form wave packet, we apply the obtained generalized parton distributions to get the Impact Parameter

Sub-Weibull distributions: generalizing sub-Gaussian and sub-Exponential properties to heavier-tailed distributions [PDF]
, 2020 We propose the notion of sub-Weibull distributions, which are characterised by tails lighter than (or equally light as) the right tail of a Weibull distribution.
