El problema de Steklov sobre el cono
Revista Integración, 2012 Sea (Mn, g) un cono de altura 0 ≤ xn+1 ≤ 1 en Rn+1, dotado con una métrica rotacionalmente invariante 2ds2 + f2(s)dw2, donde dw2 representa la métrica estándar sobre Sn−1, la esfera unitaria (n − 1)-dimensional. Supongamos que Ric(g) ≥ 0.

Quantum State‐Resolved Photodissociation Dynamics Study of Transition‐Metal Carbonyl and Nitrosyl
The Chemical Record, EarlyView.State‐resolved scattering measurements provide experimental visualization of nuclear motions in reacting molecules. Carbonyls and nitrosyls are typical ligands in most of the transition‐metal complexes, which undergo dissociation upon visible and ultraviolet photoexcitation.

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

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Anisotropic Shear Properties of Organic Interfaces in Bio‐composite Materials
Advanced Functional Materials, Volume 36, Issue 12, 9 February 2026.A novel cantilever design enables direct probing of shear properties at single organic interfaces within biocomposite prismatic ultrastructures. By decoupling lateral and torsional shear responses, the method reveals isotropic behavior in Atrina vexillum and pronounced anisotropy in Unio pictorum.
