Collisional-radiative simulation of impurity assimilation, radiative collapse and MHD dynamics after ITER shattered pellet injection [PDF]
Nuclear Fusion, 2023 Recent studies suggest significant time delay between the Shattered Pellet Injection (SPI) fragment arrival and the temperature radiative collapse could exist in ITER, depending on the impurity assimilation and the plasma thermal reservoir. Hence in some

Distinct molecular properties and functions of small EV subpopulations isolated from human umbilical cord MSCs using tangential flow filtration combined with size exclusion chromatography. [PDF]
J Extracell VesiclesTwo subpopulations of sEVs isolated from human MSCs utilizing TFF and SEC exhibited difference on size, membrane markers or cargos. Different sEVs subpopulations represented distinct biological functions of MSCs. The biogenesis of sEVs subpopulations depended on distinct intracellular pathways.

Radiative heat load distribution on the EU-DEMO first wall due to mitigated disruptions [PDF]
Nuclear Materials and Energy, 2020 The EU-DEMO First Wall (FW) will be a relatively thin structure. In order not to damage this layer, heat loads distributed onto the wall should be carefully controlled.

Density and temperature profiles after low-Z and high-Z shattered pellet injections on DIII-D
Nuclear Fusion, 2023 In this work we utilize the recently upgraded Thomson scattering diagnostic to resolve density and temperature plasma profiles after pure deuterium and mixed neon/deuterium shattered pellet injections (SPIs) on DIII-D.

Thermal quench induced by a composite pellet-produced plasmoid
Nuclear Fusion, 2023 Injecting shattered pellets is the critical concept of the envisaged ITER disruption mitigation system (DMS). Rapid deposition of large amounts of material should presumably result in controlled cooling of the entire plasma.

Protocol for Reconstituting Adaptor‐Mediated Activation of Full‐Length Kinesin‐1
Cytoskeleton, EarlyView.ABSTRACT Kinesin‐1 is a member of the kinesin superfamily that plays an essential role in intracellular cargo transport. In the absence of cargo, Kinesin‐1 exhibits low motor activity due to autoinhibition. Multiple studies have demonstrated that adaptor proteins, which link cargos to Kinesin‐1, can activate Kinesin‐1 by releasing the autoinhibition ...
