We compare three machine learning models—artificial neural network (ANN), random forest (RF), and convolutional neural network (CNN)—for spatial downscaling of temperature at 2 m above ground (T2M) from a 9 km ERA5-Land reanalysis to 1 km in a co

Past research at the Advanced Light Source (ALS) provided a proof-of-principle demonstration that deep learning methods could be effectively employed to compensate for the significant perturbations to the transverse electron beam size induced by user

The ALS-U is the upgrade of the existing Lawrence Berkeley National Laboratory Advanced Light Source to a diffraction-limited soft x-ray light source. Here we present the lattice correction studies and commissioning simulations demonstrating that the

The quality and relevance of nanosafety studies constitute major challenges to ensure their key role as a supporting tool in sustainable innovation, and subsequent competitive economic advantage. However, the number of apparently contradictory and in

We study the effect of a passive harmonic cavity, introduced to cause bunch lengthening, in an electron storage ring. We derive a formula for the induced voltage from such a cavity with high Q, excited by a sequence of bunches, allowing for arbitrary

Avec les consommations d’energies fossiles et les emissions de gaz a effet de serre reparties a la hausse, le « monde d’apres » ressemble terriblement a l’extractivisme d’avant. Et pourtant, des parametres se sont deplaces a l’occasion de

In this article, a novel matrix converter modulation, which minimizes the converter losses is proposed. This approach preserves the same voltage ratio of traditional modulations with a key concept to compute the duty cycles using only the two closest

We present a new accelerator toolbox (AT)-based toolkit for simulating the commissioning of light-source storage rings. The toolkit provides a framework for supporting high-level scripts to represent with realism the various procedures (e.g., orbit a

The Advanced Light Source Upgrade (ALS-U) is a 4th generation diffraction-limited soft x-ray radiation source, consisting of a new accumulator ring (AR) and a new storage ring (SR). In both rings coupling-impedance driven instabilities need careful e

In the agriculture sector, climate-related economic losses have reached an average of €73 bn a year worldwide. It is, hence, of utmost importance to act now to build a climate-resilient agricultural system by forecasting the future climate risk and
