Few-body decay and recombination in nuclear astrophysics [PDF]
, 2010 Three-body continuum problems are investigated for light nuclei of astrophysical relevance. We focus on three-body decays of resonances or recombination via resonances or the continuum background.

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Anchoring zero valence single atoms of nickel and iron on graphdiyne for hydrogen evolution
Nature Communications, 2018 Single atom catalysts provide the most efficient metal atoms usage and afford active site homogeneity, but surface attachment has proven challenging. Here, the authors use triple-bond-rich graphdiyne to anchor nickel/iron atoms and show high hydrogen ...

Phase Diagram for Roegenian Economics
, 2018 We recall the similarities between the concepts and techniques of Thermodynamics and Roegenian Economics. The Phase Diagram for a Roegenian economic system highlights a triple point and a critical point, with related explanations. These ideas can be used

The TWA 3 Young Triple System: Orbits, Disks, Evolution [PDF]
, 2017 We have characterized the spectroscopic orbit of the TWA 3A binary and provide preliminary families of probable solutions for the TWA 3A visual orbit as well as for the wide TWA 3A--B orbit. TWA 3 is a hierarchical triple located at 34 pc in the $\sim$10

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

A Possible Formation Scenario of the Gaia BH1: Inner Binary Merger in Triple Systems
The Astrophysical Journal LettersBased on astrometric measurements and spectral analysis from Gaia DR3, two quiescent black hole (BH) binaries, Gaia BH1 and BH2, have been identified. Their origins remain controversial, particularly for Gaia BH1.

A Property of Recombination in Polarized Hadronic Targets
, 1994 The triple gluon-ladder vertex is shown to project the outgoing gluon in either polarization state with equal probability up to the leading double-ln(x)ln($Q^2$) approximation.

FEBS Letters, EarlyView.This study reveals a unique active site enriched in methionine residues and demonstrates that these residues play a critical role by stabilizing carbocation intermediates through novel sulfur–cation interactions. Structure‐guided mutagenesis further revealed variants with significantly altered product profiles, enhancing pseudopterosin formation. These

Photometric study of HD 155555 C in the $\beta$ Pictoris Association [PDF]
, 2015 We are carrying out a series of photometric monitoring to measure the rotation periods of members in the young $\beta$ Pictoris Association, as part of the RACE-OC project (Rotation and ACtivity Evolution in Open Clusters).
