Gamma Delta T-Cell Based Cancer Immunotherapy: Past-Present-Future

open access: yesFrontiers in Immunology, 2022
γδ T-cells directly recognize and kill transformed cells independently of HLA-antigen presentation, which makes them a highly promising effector cell compartment for cancer immunotherapy.

Lava flow hazard at Fogo Volcano, Cabo Verde, before and after the 2014–2015 eruption [PDF]

open access: yesNatural Hazards and Earth System Sciences, 2016
Lava flow simulations help to better understand volcanic hazards and may assist emergency preparedness at active volcanoes. We demonstrate that at Fogo Volcano, Cabo Verde, such simulations can explain the 2014–2015 lava flow crisis and therefore ...

Lava channel formation during the 2001 eruption on Mount Etna: evidence for mechanical erosion [PDF]

open access: yes, 2005
We report the direct observation of a peculiar lava channel that was formed near the base of a parasitic cone during the 2001 eruption on Mount Etna. Erosive processes by flowing lava are commonly attributed to thermal erosion.

A lava attack on the recovery of sums of dense and sparse signals [PDF]

open access: yes, 2015
Common high-dimensional methods for prediction rely on having either a sparse signal model, a model in which most parameters are zero and there are a small number of non-zero parameters that are large in magnitude, or a dense signal model, a model with ...

Construction of probabilistic event trees for eruption forecasting at Sinabung volcano, Indonesia 2013-14 [PDF]

open access: yes, 2019
Eruptions of Sinabung volcano, Indonesia have been ongoing since 2013. Since that time, the character of eruptions has changed, from phreatic to phreatomagmatic to magmatic explosive eruptions, and from production of a lava dome that collapsed to a ...

Blood Vessel Occlusion by the Layperson Audiovisual Assist Tourniquet (LAVA TQ) Compared to the Combat Application Tourniquet: Randomized Controlled Trial

open access: yesWestern Journal of Emergency Medicine, 2023
Introduction: While windlass-rod style tourniquets stop bleeding in limbs when used by skilled responders, they are less successful in the hands of the untrained or not recently trained public.

Extracting the Weinberg angle at intermediate energies

open access: yes, 2005
A recent experiment by the NuTeV collaboration resulted in a surprisingly high value for the weak mixing angle $\sin^2 \theta_W$. The Paschos-Wolfenstein relation, relating neutrino cross sections to the Weinberg angle, is of pivotal importance in the ...
