Use of quantum quenches to probe the equilibrium current patterns of ultracold atoms in an optical lattice

, 2012
Atomic bosons and fermions in an optical lattice can realize a variety of interesting condensed matter states that support equilibrium current patterns in the presence of synthetic magnetic fields or non-abelian gauge fields.

Revealing the structure of land plant photosystem II: the journey from negative‐stain EM to cryo‐EM

FEBS Letters, EarlyView.
Advances in cryo‐EM have revealed the detailed structure of Photosystem II, a key protein complex driving photosynthesis. This review traces the journey from early low‐resolution images to high‐resolution models, highlighting how these discoveries deepen our understanding of light harvesting and energy conversion in plants.

A simple model to evaluate the heat flux onto the EU-DEMO plasma facing components during the current quench

Nuclear Fusion
A model for the plasma evolution during the current quench is presented in this paper: it allows to simulate the evolution of the phenomenon, carry on parametric studies and calculate the heat loads on the tokamak first wall.

Form of the Occurrence of Aluminium in Municipal Solid Waste Incineration Residue—Even Hydrogen Is Lost

Energies, 2022
In the bottom ash (BA) of municipal solid waste incineration, the content of iron and aluminum is relatively high. The efficiency of eddy current extraction of non-ferrous metals (including aluminium) routinely used in incineration plants is limited. The

High-speed fluorescent thermal imaging of quench propagation in high temperature superconductor tapes

, 2017
Fluorescent Microthermographic Imaging, a method using rare-earth fluorescent coatings with temperature-dependent light emission, was used for quench investigation in high temperature superconductors (HTS).

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

The effect of intrinsic tungsten impurity on unmitigated and mitigated major disruptions in ITER

Nuclear Fusion
ITER has recently decided to change the first wall (FW) material from beryllium (Be) to tungsten (W). W being a high- Z impurity behaves differently as compared to Be during normal plasma operations as well as during plasma current disruptions.

Selective Population of Edge States in a 2D Topological Band System

, 2015
We consider a system of interacting spin-one atoms in a hexagonal lattice under the presence of a synthetic gauge field. Quenching the quadratic Zeeman field is shown to lead to a dynamical instability of the edge modes.

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Simulation of DIII-D disruption with argon pellet injection and runaway electron beam

Nuclear Fusion
The next generation of large tokamaks, including ITER, will be equipped with a disruption mitigation system (DMS) that can be activated if a disruption is deemed to be imminent.
