Advances and visions in large-scale hydrological modelling : findings from the 11th Workshop on Large-Scale Hydrological Modelling [PDF]
, 2008 Large-scale hydrological modelling has become increasingly wide-spread during the last decade. An annual workshop series on large-scale hydrological modelling has provided, since 1997, a forum to the German-speaking community for discussing recent ...

Cosmological parameters from observational data on the large scale structure of the Universe
, 2000 The observational data on the large scale structure (LSS) of the Universe are used to determine cosmological parameters within the class of adiabatic inflationary models. We show that a mixed dark matter model with cosmological constant ($Λ$MDM model) and parameters $Ω_m=0.37^{+0.25}_{-0.15}$, $Ω_Λ=0.69^{+0.15}_{-0.20}$, $Ω_ν=0.03^{+0.07}_{-0.03 ...

The Astrophysical Journal, 2023 It is well known that the power spectrum is not able to fully characterize the statistical properties of non-Gaussian density fields. Recently, many different statistics have been proposed to extract information from non-Gaussian cosmological fields that

Is the Large-scale Structure Traced by the BOSS LOWZ Galaxies Consistent with Planck?
The Astrophysical Journal Letters, 2023 Recently, several studies reported a significant discrepancy between the clustering and lensing of the Baryon Oscillation Spectroscopic Survey (BOSS) galaxies in the Planck cosmology. We construct a simple yet powerful model based on the linear theory to

Local Solvent Ordering Drives Supramolecular Chirality Inversion
Advanced Science, EarlyView.Local solvent organization is shown to govern supramolecular chirality by selecting distinct chiral assembly pathways. A subtle change in water‐DMSO composition reverses the helical sense of a chiral perylene bisimide, while heating induces an irreversible thermal inversion to a more stable enantiomorph.

Programmable Sequential 4D Actuation in Multistable Kirigami Metamaterials
Advanced Science, EarlyView.This study presents a modular kirigami metamaterial framework enabling programmable multistability and sequential 4D actuation. By coupling geometry‐controlled multistability with material‐dependent recovery kinetics, spatiotemporal deformation can be precisely programmed.
