Propagation of wrinkled turbulent flames in the context of hydrodynamic theory

open access: yes, 2011
We study the propagation of premixed flames in two-dimensional homogeneous isotropic turbulence using a Navier-Stokes/front-capturing methodology within the context of hydrodynamic theory. The flame is treated as a thin layer separating burnt and unburnt

Endogenous Technology Spillovers in R&D Collaboration Networks

open access: yesThe RAND Journal of Economics, Volume 56, Issue 4, Page 419-443, Winter 2025.
ABSTRACT We introduce an R&D network formation model where firms choose both R&D efforts and collaboration partners. Neighbors in the network benefit from each other's R&D through technology spillovers, and there exists competition effects reflecting strategic substitutability in R&D.

Whole‐genome data shed light on speciation and within‐species differentiation of the Papilio machaon complex around the Mediterranean Basin

open access: yesSystematic Entomology, Volume 50, Issue 4, Page 692-712, October 2025.
Genomic data refine the species boundary of Papilio machaon and confirm the species status of Papilio saharae, with clarification of subspecies delineation of Mediterranean machaon and saharae. A heterogeneous level of genome‐wide heterozygosity between island and continental lineages warrants further taxonomic implications, and there is also evidence ...

European Biometric Borders and (Im)Mobilities in West Africa: Reflections on Migrant Strategies for Border Circumvention and Subversion

open access: yesPolitics &Policy, Volume 53, Issue 1, February 2025.
ABSTRACT This article argues that the European biometric ID installations and securitization practices at West African borders harm African migrants and compromise the security goals of Europe and Africa. Using Niger's experience, I contend that migrants' poor adaption to the biometric border processes is closely connected to their identity conflicts ...

Placenta accreta spectrum: imaging and diagnosis

open access: yesThe Obstetrician &Gynaecologist, Volume 27, Issue 1, Page 15-28, January 2025.
Key content Antenatal imaging is a screening tool integral to ensuring women are cared for in the most appropriate setting. The pretest probability of PAS should be considered before any imaging is performed. PAS is an iatrogenic disease. Any process which disrupts the endometrium increases the risk. Caesarean birth is the most common cause. Specialist
