A kernel‐based change detection method to map shifts in phytoplankton communities measured by flow cytometry

Automated, ship-board flow cytometers provide high-resolution maps of phytoplankton composition over large swaths of the world's oceans. They therefore pave the way for understanding how environmental conditions shape community structure. Identification o ...

In vitro acute toxicity assessment of tire tread particles using rainbow trout cell lines of gill and intestine

Kristin Schirmer, Florian Frédéric Vincent Breider, Benoît Jean Dominique Ferrari, Thibault Béranger Masset

Tire and road wear particles (TRWP) are generated by the abrasion of tires while driving, and recent questions were raised in regards to their potential contribution to microplastics released into the aquatic environment and their potential toxicological i ...

Implementation of energy transfer technique in ORB5 to study collisionless wave-particle interactions in phase-space

Laurent Villard, Emmanuel Lanti, Alberto Bottino, Noé Thomas Elie Ohana, Emanuele Poli

A new diagnostic has been developed to investigate the wave-particle interaction in the phase-space in gyrokinetic particle-in-cell codes. Keeping information about energy transfer terms in the velocity space, the technique has been implemented and tested ...

Similarity conditions and cube model tests of snow drift and precipitation preferential deposition patterns

Michael Lehning, Borui Zhang, Qingwen Zhang

We explore the process of modeling aeolian snow transport around buildings by proposing a set of similarity requirements on simulating a single snow fall event with drifting. The similarity criteria are used to guide our wind tunnel tests from the particle ...

Concentration of particles larger than 2.5 nm collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The concentration of particles larger than 2.5 nm was measured with an ultrafine condensation particle counter (UCPC). The concentration was corrected for diffusional losses in the inlet based on the neutral cluster and air ion spectrometer (NAIS) size dis ...

Size distribution of neutral and charged particles smaller than 42 nm collected during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The size distribution of neutral and charged particles was measured using a neutral cluster and air ion spectrometer (NAIS) instrument. The concentration was corrected for diffusional losses in the inlet. The concentration and temporal dynamics of small pa ...

Ultrafine particle concentration measured during the Arctic Ocean 2018 expedition

Julia Schmale, Andrea Baccarini

The ultrafine particle (UFP) concentration is the concentration of particles having a diameter between 2.5 and 15 nm, it is reported in terms of particle number per cubic centimeter at a time resolution of 10 minutes. UFP are the smallest particles within ...

Methods and systems for particle characterisation

Sandor Kasas, Anton Malovichko

A method and system for deriving particle characteristics is described. The method comprises imaging the movement of at least one free-floating particle in a liquid environment at at least one moment in time, determining for at least one moment in time a m ...

Lagrangian Discretization Of Crowd Motion And Linear Diffusion

Federico Stra

We study a model of crowd motion following a gradient vector field, with possibly additional interaction terms such as attraction/repulsion, and we present a numerical scheme for its solution through a Lagrangian discretization. The density constraint of t ...
