Dynamical density-density correlations in one-dimensional Mott insulators
, 1996 The dynamical density-density correlation function is calculated for the one-dimensional, half-filled Hubbard model extended with nearest neighbor repulsion using the Lanczos algorithm for finite size systems and analytically for large on site repulsion ...

FEBS Letters, EarlyView.Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Minimum Density Hyperplanes [PDF]
, 2016 Associating distinct groups of objects (clusters) with contiguous regions of high probability density (high-density clusters), is central to many statistical and machine learning approaches to the classification of unlabelled data.

Density waves and $1/f$ density fluctuations in granular flow
, 1994 We simulate the granular flow in a narrow pipe with a lattice-gas automaton model. We find that the density in the system is characterized by two features.

FEBS Letters, EarlyView.To explore the impact of the overexpression of the multidrug‐transporter P‐glycoprotein (ABCB1) on membrane fluidity, we compared the transversal gradient of mobility and microviscosity in plasma membranes of drug‐sensitive Chinese hamster ovary cells (AuxB1) and their multidrug‐resistant derivatives (B30) using the fluorescent n‐(9‐anthroyloxy) fatty ...

Associations of residential walkability and greenness with arterial stiffness in the UK Biobank
Environment International, 2022 Background: Arterial stiffness is a key non-invasive marker of early vascular ageing, however, little is known of its associations with urban built environment.

, 2013 The microscopic composition and properties of matter at super-saturation densities have been the subject of intense investigation for decades. The scarcity of experimental and observational data has lead to the necessary reliance on theoretical models ...

Phonons and related crystal properties from density-functional perturbation theory [PDF]
, 2000 This article reviews the current status of lattice-dynamical calculations in crystals, using density-functional perturbation theory, with emphasis on the plane-wave pseudopotential method.

Evolutionary interplay between viruses and R‐loops
FEBS Letters, EarlyView.Viruses interact with specialized nucleic acid structures called R‐loops to influence host transcription, epigenetic states, latency, and immune evasion. This Perspective examines the roles of R‐loops in viral replication, integration, and silencing, and how viruses co‐opt or avoid these structures.

Bone Density Status and Vitamin D and Calcium Concentrations in Pregnant and Non-Pregnant Women [PDF]
, 2016 Background: The aim of this study was to analyse differences in bone density and vitamin D and calcium concentrations between pregnant and non-pregnant women. Methods: This was an analytical, cross-sectional study of women aged 30 years or over, residing
