Accelerating brain T2-weighted imaging using artificial intelligence–assisted compressed sensing combined with deep learning-based reconstruction: a feasibility study at 5.0T MRI

BMC Medical Imaging
Background T2-weighted imaging (T2WI), renowned for its sensitivity to edema and lesions, faces clinical limitations due to prolonged scanning time, increasing patient discomfort, and motion artifacts.

Thermoluminescence fading studies: Implications for long-duration space measurements in Low Earth Orbit

, 2013
Within a 1.5 year comprehensive fading experiment several batches of LiF:Mg,Ti and LiF:Mg,Cu,P thermoluminescence detectors (TLDs) were studied. The TLDs originated from two manufacturers and were processed by three laboratories using different annealing

Open letter: The need for a site‐based biodiversity standard measuring and certifying impacts from nature‐based projects

PLANTS, PEOPLE, PLANET, EarlyView.
Despite growing investment in restoration, weak accountability and poor biodiversity monitoring mean many projects fail to achieve ecological recovery. The Global Biodiversity Standard (TGBS) offers a practical way to ensure that restoration finance delivers measurable gains for nature.

Status and future of seed conservation of threatened plants in the post‐2020 era

PLANTS, PEOPLE, PLANET, EarlyView.
Ambitious targets have been set to backup seeds of threatened plants by the global strategy for plant conservation (GSPC), but it is unclear in how far these targets have been met and how seed collection should be organized to meet future challenges. Here, we provide an overview of the status of 44 countries in achieving seed conservation targets.

Evaluation of a High‐Performance Monopropellant Formed of Microencapsulated Hydrocarbon Fuels in Combination With Gelled Hydrogen Peroxide in a Strand Burner Setup

Propellants, Explosives, Pyrotechnics, EarlyView.
A high‐performance premixed monopropellant is prepared from hydrocarbon‐filled microcapsules and hydrogen peroxide. This propellant is burned in a strand burner, and the effect of different parameters on the burn rate is evaluated. ABSTRACT A dispersion of hydrocarbon‐fuel‐filled microcapsules in gelled hydrogen peroxide can form a premixed ...

Standard State Space Models of Unawareness [PDF]

, 2015
The impossibility theorem of Dekel, Lipman and Rustichini has been thought to demonstrate that standard state-space models cannot be used to represent unawareness.

Moisture inversions in the central Arctic: Product assessment and long‐wave radiative effect

Quarterly Journal of the Royal Meteorological Society, EarlyView.
This study evaluates the integrated water vapour and the vertical distribution of water vapour of state‐of‐the‐art reanalyses, weather forecast models, and ground‐ and space‐based remote‐sensing products in the central Arctic. A particular focus lies on the representation of humidity inversions and the quantification of the long‐wave radiative effect ...
