The transverse nuclear response for quasifree electron scattering is discussed. The analysis is done by comparing different calculations performed in the random-phase approximation and ring approximation frameworks. The importance of the exchange terms in this energy region is investigated and the changes in the nuclear responses due to the modification of the interaction are evaluated. The cal...

The past decade has witnessed the development and success of coarse-grained network models of proteins for predicting many equilibrium properties related to collective modes of motion. Curiously, the results are usually robust towards the different methodologies used for constructing the residue networks from knowledge of the experimental coordinates. We present a systematical study of network ...

This paper studies human capital investment in a spatial setting with interpersonal complementarities. A mixture of local and global social interactions affect the cost of acquiring education, and the return to human capital is determined endogenously in the market. We study how spatially segregated investment equilibria are affected by an increase in the relative importance of global vis-á-vis...

We consider two ways of introducing minimal Abelian gauge interactions into the model presented in [1]. They are different only if the second central charge of the planar Galilei group is nonzero. One way leads to standard gauge transformations and second to a generalized gauge theory with gauge transformations accompanied by time-dependent area-preserving coordinate transformations. Both appro...

We construct many particle Hamiltonians for which the Laughlin and Jain wavefunctions are exact ground states. The Hamiltonians involve fermions in a magnetic field and with inter-particle interactions. For the Laughlin wave-functions and unprojected Jain wave-functions, the interactions involve twoand three-body correlations similar to the Chern-Simons interactions, whereas for the projected J...

To simulate the effect of free st ream turbulence on turbulent spot formation, experiments were conducted on the interaction of localized three-dimensional disturbances with the harmonic waves in a laminar boundary layer on a flat plate. Experiments conducted in three-dimensional diverging flow (but zero pressure gradient) show, while individually the disturbances decay downstream, their intera...

leadership style and organizational climate are considered as a substructure framework in successful performance of knowledge management. the purpose of this research is investigating both the effect of leadership style and organizational climate on knowledge management and the moderate role of organization structure and social interaction in affecting leadership style and organizational climat...
