Toward an Efficient Shifted Cholesky QR for Applications in Model Order Reduction Using pyMOR

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT Many model order reduction (MOR) methods rely on the computation of an orthonormal basis of a subspace onto which the large full order model is projected. Numerically, this entails the orthogonalization of a set of vectors. The nature of the MOR process imposes several requirements for the orthogonalization process.

Experimental characterisation of ITER electric cables in postulated fire scenarios

, 2012
International audiencePower and control cables account for roughly 70% of all ITER fire loads. Fire experiments were executed at IRSN Cadarache to test several industrial cables in order to ensure that the specificities of the ITER project could be ...

Toward a Mixed‐Precision ADI Method for Lyapunov Equations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 2, June 2026.
ABSTRACT We apply mixed‐precision to the low‐rank Lyapunov ADI (LR‐ADI) by performing certain aspects of the algorithm in a lower working precision. Namely, we accumulate the overall solution, solve the linear systems comprising the ADI iteration, and store the inner low‐rank factors of the residuals in various combinations of IEEE 754 single and ...

Exploring ionic behavior: conductance studies of L-glutamic acid in aqueous D-sorbitol across temperature gradients

BMC Chemistry
In this paper molecular interactions of L-glutamic acid (Glu) in aqueous D-sorbitol (D-SOR) are analyzed by measuring electrical conductivity in the broad temperature range of 293.15–313.15 K at ambient pressure.

A phylogenomic framework for species delimitation in Kirganelia (Phyllanthaceae): Tracing a history of reticulate evolution

TAXON, Volume 75, Issue 3, June 2026.
Abstract Kirganelia (Phyllanthaceae) is a palaeotropical genus recently reinstated as separate from Phyllanthus, yet species boundaries remain unclear, especially within the widespread and morphologically variable K. reticulata complex. To resolve this, we generated Angiosperms353‐based phylogenomic data from 233 samples and applied an integrative ...

Modelling the neutralisation process in neutral beam injectors [PDF]

, 2009
High power neutral beams currently play an important role in heating, fuelling and diagnosing magnetically confined thermonuclear fusion plasmas. At the Joint European Torus (JET) in Oxfordshire, England, the formation of such a beam involves passing a ...

Haplotype‑resolved comparison of transcription factor superfamilies between wild and cultivated autotetraploid green jujube and prioritization of candidate transcription factors via machine learning

The Plant Genome, Volume 19, Issue 2, June 2026.
Abstract A framework beyond single‐reference genomes is needed to understand transcription factor evolution. This study employed an integrated haplotype‑resolved genomes–transcriptome atlas–machine learning to characterize the transcription factors of autotetraploid green jujube (Ziziphus mauritiana).

Impacts of mechanical fields on hydrogen transport in ITER divertor monoblocks

, 2022
International audienceIn nuclear fusion devices, plasma facing components are submitted to intense hydrogen isotopes and heat fluxes. The most exposed component of tokamak is the divertor, which in ITER is composed of tungsten monoblocks.

A Deep Learning‐Enhanced Ensemble Smoother for Non‐Gaussian Hydrological Data Assimilation Without Relying on Innovation Vectors

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 3, June 2026.
Abstract Data assimilation (DA) plays a critical role in reducing simulation uncertainty in hydrological systems by leveraging available observations to estimate model states and/or parameters. Among DA methods, the ensemble smoother (ES) has emerged as an attractive option for parameter estimation due to its computational efficiency and ...
