DOI: 10.1002/esp.4420
Abstract: Estimates of the wind shear stress exerted on Earth’s surface using the fully rough form of the law-of-the-wall are a function of the aerodynamic roughness length, z0. Accurate prediction of aeolian sediment transport rates, therefore,… read more here.

DOI: 10.1017/jfm.2025.10498
Abstract: Abstract We study aeolian saltation over an erodible bed at full transport capacity in a wind tunnel with a relatively thick boundary layer. Lagrangian tracking of size-selected spherical particles resolves their concentration, velocity and acceleration.… read more here.

DOI: 10.1021/acs.est.2c05396
Abstract: Saltation is an important wind erosion process that can cause the modification and breakdown of particles by aeolian abrasion. It is recognized that microplastic particles can be transported by wind, but the effect of saltation… read more here.

DOI: 10.1111/gere.12249
Abstract: Abstract The quantification of saltation intermittency—the proportion of time when sand transport occurs—provides valuable information about the nature of aeolian systems, including insights concerning threshold conditions for sand transport. Intermittency has been measured in numerous… read more here.

DOI: 10.1126/sciadv.1602569
Abstract: Field data show insensitivity of particle trajectories to wind speed and support linear scaling of sand flux with wind stress. Wind-driven sand transport generates atmospheric dust, forms dunes, and sculpts landscapes. However, it remains unclear… read more here.

DOI: 10.3389/fncel.2017.00045
Abstract: In cortical pyramidal neurons the presynaptic terminals controlling transmitter release are located along unmyelinated axon collaterals, far from the original action potential (AP) initiation site, the axon initial segment (AIS). Once initiated, APs will need… read more here.
