Mapping the effects of specific radiation damage and solvent radiolysis in buffers and crystals with online UV–Vis absorption spectroscopy

open access: yesActa Crystallographica Section D, EarlyView.
Radiation‐induced changes during X‐ray crystallographic data collection can compromise concurrent spectroscopic studies. Suitable protocols to detect and identify spectral artefacts from crystallization buffers and cryoprotectants are essential for the reliable analysis of chromophoric ligands in macromolecules.Online UV–Vis absorption spectroscopy is ...

Razionamento del credito e dimensioni di impresa (Credit rationing and firm size)

open access: yesMoneta e Credito, 2012
This paper examines the likelihood of credit rationing faced by firms of dif­ferent size. Cantrary to common thought, several recent contributions on this topic argue that, when rationing credit, size alone is not a sufficient con­dition for ...

Dark Matter attempts for CoGeNT and DAMA

open access: yes, 2011
Recently, the CoGeNT collaboration presented a positive signal for an annual modulation in their data set. In light of the long standing annual modulation signal in DAMA/LIBRA, we analyze the compatibility of both of these signal within the hypothesis of

Cryo‐EM reveals ArnA contamination during purification of a ciliary protein complex

open access: yesActa Crystallographica Section D, EarlyView.
ArnA contamination was independently observed during the purification of a soluble, low‐yield protein complex, leading to an unintended 3.23 Å resolution cryo‐EM structure. This work broadens recent findings and highlights ArnA as a recurrent His‐tag‐associated contaminant in Escherichia coli purification workflows.Endogenous Escherichia coli proteins ...

Alphafuser: a parsimonious approach to predicting higher‐order protein complexes

open access: yesActa Crystallographica Section D, EarlyView.
Alphafuser is a structure‐prediction pipeline that integrates experimental interaction data with AlphaFold‐based modeling to systematically assemble multiprotein complexes in a computationally efficient manner. By implementing an ipTM‐based pruning algorithm and validating against known structures and experimental assays, Alphafuser enables the ...

Parity Doubling and the S Parameter Below the Conformal Window [PDF]

open access: yes, 2010
We describe a lattice simulation of the masses and decay constants of the lowest-lying vector and axial resonances, and the electroweak S parameter, in an SU(3) gauge theory with $N_f = 2$ and 6 fermions in the fundamental representation.

Creative Discretion on the Frontline of Public Services: A Longitudinal Qualitative Digital Diary and Interview Study

open access: yesPublic Administration, EarlyView.
ABSTRACT “Creative discretion”—defined as street‐level bureaucrats' use of their discretion to generate novel and useful ideas for customizing services to meet the needs of service users, superiors, and themselves—is vital as governments shift from traditional public management to a more user‐centered approach, emphasizing responsiveness over ...

Strategic materials and state capacity in Renaissance Italy: The economic policies of ‘Roman saltpetre’ procurement

open access: yesThe Economic History Review, Volume 79, Issue 2, Page 757-780, May 2026.
Abstract Demonstrating the existence of a soaring demand for strategic materials in fifteenth‐century Rome, the article pioneers research in the late medieval trade in saltpetre, the irreplaceable, rare component of gunpowder, indispensable for waging war following the diffusion of artillery technology.
