A New Tool for Automated Quality Control of Environmental Data in Open Web Services
We report on the development of a new software tool (auto-qc) for automated quality control (QC) of environmental timeseries data. Novel features of this tool include a flexible Python software architecture, which makes it easy for users to configure the sequence of tests as well as their statistical parameters, and a statistical concept to assign each value a probability of being a correct value.

Targeted CCUS R&D activities in industrial clusters
Although initial CCUS demonstration projects are planned to commence as point-to-point projects, with a single pipeline or ships linking one source to one sink, the concept of ‘CCUS clusters’ is considered to be crucial to maximize the climate change mitigation potential of the technology. This work is part of ALIGN-CCUS, currently one of the largest European R&D projects on CCUS, with a work programme designed to enable the acceleration of CCUS in specific industrial regions in ERA-NET countries: Teesside and Grangemouth (UK), Rotterdam (NL), North Rhine-Westphalia (DE), Grenland (NO) and Oltenia (RO).

Excitons in InGaAs Quantum Dots without Electron Wetting Layer States
The Stranski-Krastanov (SK) growth-mode facilitates the self-assembly of quantum dots (QDs) using lattice-mismatched semiconductors, for instance InAs and GaAs. SK QDs are defect-free and can be embedded in heterostructures and nano-engineered devices. [...]

Transfer of a quantum state from a photonic qubit to a gate-defined quantum dot
Interconnecting well-functioning, scalable stationary qubits and photonic qubits could substantially advance quantum communication applications and serve to link future quantum processors. Here, we present two protocols for transferring the state of a photonic qubit to a single-spin and to a two-spin qubit hosted in gate-defined quantum dots (GDQD). [...]

Plasma impurities in linear, hot cathode, arc-plasma devices studied with D2 and He-plasmas in PSI-2
Linear plasma devices are being used for studies of plasma-surface interaction. Hot-cathode arc-discharge devices such as PSI-2 can provide flux densities in the 10^23 ions/m²s order at electron temperatures of 1-20eV. [...]

Dense Fiber Modeling for 3D-Polarized Light Imaging Simulations
3D-Polarized Light Imaging (3D-PLI) is a neuroimaging technique used to study the structural connectivity of the human brain at the meso- and microscale. In 3D-PLI, the complex nerve fiber architecture of the brain is characterized by 3D orientation vector fields that are derived from birefringence measurements of unstained histological brain sections by means of an effective physical model.

Simulating the weak death of the neutron in a femtoscale universe with near-Exascale computing
[LLNL-JRNL-749850]
The fundamental particle theory called Quantum Chromodynamics (QCD) dictates everything about protons and neutrons, from their intrinsic properties to interactions that bind them into atomic nuclei. Quantities that cannot be fully resolved through experiment, such as the neutron lifetime (whose precise value is important for the existence of light-atomic elements that make the sun shine and life possible), may be understood through numerical solutions to QCD.

Avoiding Ergodicity Problems in Lattice Discretizations of the Hubbard Model
The Hubbard model arises naturally when electron-electron interactions are added to the tight-binding descriptions of many condensed matter systems. For instance, the two-dimensional Hubbard model on the honeycomb lattice is central to the ab initio description of the electronic structure of carbon nanomaterials, such as graphene. [...]

Expansion coefficient of the pseudo-scalar density using the gradient flow in lattice QCD
We use the Yang-Mills gradient flow to calculate the pseudo-scalar expansion coefficient $c_P^*(t_f)$. This quantity is a key ingredient to obtaining the chiral condensate and strange quark content of the nucleon using the Lattice QCD formulation, which can ultimately determine the spin independent (SI) elastic cross section of dark matter models involving WIMP-nucleon interactions.
