The Density Parity Model for the Evolution of the Subhalo Inner Spin Alignments with the Cosmic Web

open access: yesThe Astrophysical Journal, 2023
We develop a new model within which the radius-dependent transition of the subhalo inner spins with respect to the cosmic web and the variation of the transition threshold radius ( r _th ) with subhalo mass ( M _vir ), smoothing scale ( r _f ), and ...

Transforming Inner Alchemical Vision into Painting: Huang Gongwang’s Clearing after Sudden Snow

open access: yesReligions, 2023
This paper argues that the Yuan dynasty Daoist Huang Gongwang’s 黃公望 (1269–1354) painting Clearing after Sudden Snow resonates with the principles of inner alchemy (neidan, 內丹), particularly the stage known as the resurgence of yang force.

The EB-MB Transition at Tell Afis: a Reappraisal

open access: yesAsia Anteriore Antica, 2022
The passage from the 3rd to the 2nd millennium BC in Inner Syria is still a matter for debate both in historical and archaeological studies. This is only partially due to lack of evidence: it is much the way one interprets the extant evidence that ...

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation

open access: yesFEBS Letters, EarlyView.
Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

Protein import into chloroplasts: new aspects of a well-known topic [PDF]

open access: yes, 2007
Protein import into plant chloroplasts is a fascinating topic that is being investigated by many research groups. Since the majority of chloroplast proteins are synthesised as precursor proteins in the cytosol, they have to be posttranslationally ...

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.

Residual tail twisting in ascidian larvae is stabilized by asymmetric myofibrils that resist bilateral symmetry restoration

open access: yesFEBS Letters, EarlyView.
Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Ab initio simulations of iron-nickel alloys at Earth's core conditions

open access: yes, 2012
We report ab initio density functional theory calculations on iron–nickel (FeNi) alloys at conditions representative of the Earth's inner core. We test different concentrations of Ni, up to ∼39 wt% using ab initio lattice dynamics, and investigate the ...

Computational Characterization of Single-Electron Transfer Steps in Water Oxidation

open access: yesInorganics, 2019
The presence of single-electron transfer (SET) steps in water oxidation processes catalyzed by first-row transition metal complexes has been recently recognized, but the computational characterization of this type of process is not trivial.
