Alianzas y política: un juego entre agentes civiles y armados

Lecturas de Economía, 2007
Uno de los propósitos de los agentes armados en guerras irregulares es reemplazar al Estado en el monopolio de la violencia y en la protección de la población civil.

Structural basis of regioselective double halogenation of the β‐carboline tryptoline by the single‐component halogenase AetF

Acta Crystallographica Section D, EarlyView.
A structure of the flavin‐dependent single‐component tryptophan halogenase AetF bound to the non‐native tricyclic substrate tryptoline reveals a binding pose analogous to l‐tryptophan that directs C6‐first halogenation. Product analysis identifies 6,8‐dibromotryptoline as the final product.Flavin‐dependent halogenases (FDHs) offer a biocatalytic route ...

Central banks and information provided to the private sector

PSL Quarterly Review, 2012
This paper examines the information provided to the private sector by central banks. By using the principal component analysis, we investigated the variance of the procedural rules followed by nine major central banks about informationtreatments.

Structural insights into urocanate reductase using room‐temperature X‐ray crystallography

Acta Crystallographica Section D, Volume 82, Issue 6, Page 603-614, June 2026.
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.

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

Moneta 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 ...

Peptide binding at the gasdermin D exosite reveals the structural basis for targeting the site

Acta Crystallographica Section D, Volume 82, Issue 6, Page 615-625, June 2026.
We describe the first structure of gasdermin D with a putative caspase inhibitor peptide analog at 1.6 Å resolution. This work suggests potential druggability of gasdermin D at the exosite by leveraging structure‐based computational design with biochemical characterization.Gasdermin D (GSDMD) has been identified as a critical component of the ...

Rational acquisition of laboratory equipment: an accurate mathematical model to estimate the trade‐offs in shared and nonshared equipment

Acta Crystallographica Section D, Volume 82, Issue 6, Page 638-645, June 2026.
We present a quantitative framework combining cost modelling and queueing theory to estimate hourly access costs, waiting times and congestion levels for shared high‐end scientific equipment. The approach is general, illustrated with cryo‐electron microscopy examples, and implemented in an open‐access online calculator to support evidence‐based ...

Public data openness and digital financial inclusion: Evidence from Chinese cities

International Review of Economics & Finance
Information asymmetry remains a central barrier to financial inclusion, yet whether government data openness can alleviate this friction lacks causal evidence.
