Small, EarlyView.Electron nanodiffraction mapping was used to determine that the 3D leg configuration of branched plasmonic AuAg nanostars is associated with the icosahedral symmetry of the star core, providing a deeper understanding of their growth mechanism and thus paving the way to the development of optimized synthesis protocols targeting optical enhancement ...

A family of complex nilmanifolds with infinitely many real homotopy types [PDF]
, 2017 We find a one-parameter family of non-isomorphic nilpotent Lie algebras $\mathfrak{g}_a$, with $a \in [0,\infty)$, of real dimension eight with (strongly non-nilpotent) complex structures.

Structural insights into urocanate reductase using room‐temperature X‐ray crystallography
Acta Crystallographica Section D, EarlyView.The active‐site dynamics of the microbial enzyme urocanate reductase were revealed by room‐temperature X‐ray crystallography.Urocanate reductase (UrdA) is a bacterial enzyme that converts urocanic acid to imidazole propionate. Its catalytic residue Arg411 undergoes a large conformational change in the substrate‐bound versus product‐bound states.

The Price Gap in Agriculture‐Based Greenhouse Gas Offset Markets
Australian Journal of Agricultural and Resource Economics, EarlyView.ABSTRACT Today, there is a global effort to reduce greenhouse gas net emissions (GHGNE). For economic well‐being, it is important to identify low‐cost means of net emission offsets. Agriculture and forestry have received considerable attention as a means of supplying emissions offsets, as they contribute nearly 20% of global emissions.

Gender &History, EarlyView.ABSTRACT In Spain, under General Franco's regime, homosexuality was regarded as an antisocial and dangerous behaviour. It was thus pursued both by the police and judicial courts. The Law on Vagrants and Crooks (1954) and, subsequently, the Law on Dangerousness and Social Rehabilitation (1970) constituted the legal mechanisms used by the dictatorship to

GRB 021004: Tomography of a gamma-ray burst progenitor and its host galaxy [PDF]
, 2010 We analyse the distribution of matter around the progenitor star of gamma-ray burst GRB 021004 as well as the properties of its host galaxy with high-resolution echelle as well as near-infrared spectroscopy. Observations were taken by the 8.2m Very Large

Integrative Zoology, EarlyView.Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.
