Niños portadores de una válvula de derivación de líquido cefalorraquídeo: motivos de consulta, diagnósticos y consumo de recursos en el servicio de urgencias [PDF]

open access: yes, 2018
Objetivos: Determinar los motivos de consulta en el servicio de urgencias de los niños portadores de válvula de derivación de líquido cefalorraquídeo (VDL), así como sus diagnósticos al alta, y comparar el consumo de recursos que generan con el de la ...

$U(1)$ flavour symmetries as Peccei-Quinn symmetries

open access: yes, 2019
We investigate to what extent a generic, generation-dependent $U(1)$ symmetry acting on the quark Yukawa operators can reduce the number of free parameters by forcing some entries in the Yukawa matrices to vanish. The maximal reduction compatible with CP

The Origin and Diversification of Turmerics (Curcuma L.: Zingiberaceae) in Paleotropical Biodiversity Hotspots: The Role of Ancient Hybridisation and Historical Climate Change

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 5, May 2026.
ABSTRACT Aim To investigate the ecological and evolutionary mechanisms driving biodiversity in the Indo‐Malayan hotspots, with a particular focus on the roles of ancient hybridisation and historical climate in shaping species diversity. Location The Indo‐Malayan realm, particularly the Western Ghats‐Sri Lanka and Indo‐Burma biodiversity hotspots.

Irreducible Characters of Kac-Moody Lie superalgebras

open access: yes, 2014
Generalizing the super duality formalism for finite-dimensional Lie superalgebras of type $ABCD$, we establish an equivalence between parabolic BGG categories of a Kac-Moody Lie superalgebra and a Kac-Moody Lie algebra.

Dendritic Nano‐Based Slippery Coating by Synergistic Mechanical and Electrostatic Interactions with Persistent and Exceptional Combats Thrombosis

open access: yesAdvanced Science, Volume 13, Issue 19, 2 April 2026.
A novel dendritic nano‐based slippery coating (DNSC), fabricated by encapsulating carboxyl silicone oil within amino dendritic silica nanoparticles and co‐embedding them in an epoxy resin matrix. The dendritic architecture enhances nanoparticle dispersion in the matrix and establishes mechanical interlock.

Progression‐Free Survival 2 as a Potential Surrogate for Overall Survival in Glioblastoma: Insights From a Spanish Multicentric Cohort

open access: yesCancer Medicine, Volume 15, Issue 4, April 2026.
Overall, PFS2 correlated more strongly with OS than PFS (0.83 vs. 0.69). PFS2 outperformed PFS in patients with targetable alterations and in those without. Our findings support using PFS2 as a candidate surrogate endpoint in glioblastoma trials. Implementing PFS2 balances trial feasibility with clinical relevance of outcomes.

The effects of stellar dynamics on the X-ray emission of flat early-type galaxies

open access: yes, 2014
Observational and numerical studies gave hints that the hot gaseous haloes of ETGs may be sensitive to the galaxy internal kinematics. By using high resolution 2D hydro simulations, and realistic two-component (stars plus dark matter) axisymmetric galaxy

Effective forces in square well and square shoulder fluids

open access: yes, 2010
We derive an analytical expression for the effective force between a pair of macrospheres immersed in a sea of microspheres, in the case where the interaction between the two unlike species is assumed to be a square well or a square shoulder of given ...

Gauge-invariant implications of the LHCb measurements on Lepton-Flavour Non-Universality

open access: yes, 2017
We study the implications of the recent measurements of $R_K$ and $R_{K^*}$ by the LHCb collaboration. We do that by adopting a model-independent approach based on the Standard Model Effective Field Theory (SMEFT), in which the dominant new physics ...
