Anthropology of Islamic Law
No full textIn collaboration with Utrecht University, Leiden University, and the University of Amsterdam, the ISIM organized a workshop on the anthropology of Islamic law in Leiden from 14 to 15 March 2003. Convened by Leon Buskens, Khalid Masud, and Annelies Moors, the workshop brought together a group of scholars working on Islamic law and practice in different parts of the world, in the fields of anthropology, history, and legal scholarship
Application of Islamic Law in Courts
No full textFrom 26 to 28 October 2001, the ISIM, in collaboration with the University of Amsterdam and Cornell University, held an international conference in Leiden on the 'Application of Islamic Law in Courts'. The conference conveners, Muhammad Khalid Masud, Rudolph Peters and David Powers, invited historians, lawyers, anthropologists and sociologists to come to Leiden to engage in a discussion on the manner in which Islamic legal doctrine (fiqh) has manifested itself in daily practice as reflected in the activity of the qadi, or Muslim judge
Muslim Jurists' Quest for the Normative Basis of Sharia
No full textMuhammad Khalid Masud, ISIM Chair at Leiden University and Academic Director of the ISIM, delivered his inaugural lecture on 'Muslim Jurists' Quest for the Normative Basis of Sharia' on 20 October 2000. In the lecture, he argued that the conception of the S h a r ia as divine law has problematized the binding nature of law in Islam because it conceals its material bases in the social norms. It also obscures Muslim jurists' continuous efforts to maintain general acceptance of Islamic law by bringing the legal norms closer to social norms. He argued that the current debates on the Sharia are also triggered by this conception as it ignores the inner contradictions between legal and social norms emerging in contemporary Muslim societies. The following contains a few excerpts from this lecture

A Unified Shell model for Buoyancy-Driven Turbulence
No full textWe construct a unified shell model for stably stratified and convective turbulence. Shell model simulation of stably stratified flow in turbulent regime exhibit Bolgiano-Obukhbov (BO) scaling in which the kinetic energy spectrum varies as . However, simulation of convective turbulence shows Kolmogorov's spectrum. These results are consistent with the direct numerical simulations of Kumar {\em et al.} [Phys. Rev. E {\bf 90}, 023016 (2014)]. We also observe a dual scaling ( and ) for a limited range of parameters in stably stratified flow
Sweeping has no effect on renormalized turbulent viscosity
No full textWe perform renormalization group analysis (RG) of the Navier-Stokes equation in the presence of constant mean velocity field , and show that the renormalized viscosity is unaffected by , thus negating the ``sweeping effect", proposed by Kraichnan [Phys. Fluids {\bf 7}, 1723 (1964)] using random Galilean invariance. Using direct numerical simulation, we show that the correlation functions for and differ from each other, but the renormalized viscosity for the two cases are the same. Our numerical results are consistent with the RG calculations
Energy transfers in small-scale and large-scale dynamos
No full textWe study energy transfers during magnetic energy growth in small-scale and large-scale dynamos. We perform direct numerical simulations for magnetic Prandtl number Pm =20 and 0.2 in a periodic box on 1024^3 grid. Energy fluxes and shell-to-shell energy transfers indicate that in small-scale dynamo for Pm =20, the magnetic energy growth takes place due to a non-local energy transfer from large-scale velocity field to small-scale magnetic field. On the other hand, in large-scale dynamo for Pm =0.2, local energy transfers from large-scale velocity field to large-scale magnetic field takes place
Author Correction: Long-range chiral exchange interaction in synthetic antiferromagnets
No full textIn the version of this Article originally published, the sentence ‘D.-S.H. wrote the paper with K.L., J.H. and M.K.’ in the author contributions was incorrect; it should have read ‘D.-S.H. wrote the paper with K.L., J.H., M.-H.J. and M.K.’ This has been corrected in the online versions of the Article
Implicit large-eddy simulation of the stratocumulus-topped boundary layer: A grid sensitivity study
No full textA range of implicit large-eddy simulations of the stratocumulus-topped boundary layer is performed to study the influence of grid resolution on selected parameters including liquid water path and second and third moments of vertical velocity fluctuations. The simulations are based on two sets of aircraft measurements, which are also used to evaluate the results of the simulations. The specific case presented here indicates that simulations with a grid aspect ratio accounting for the anisotropic nature of the turbulence near the surface and at the top of the boundary layer lead to better agreement with measurements than simulations with an isotropic grid
