Global Financial and Economic Crisis: Implications for Trade and Industrial Restructuring in South Asia
This study investigates the impact of global crisis shocks on India's trade and industry. The authors use panel data modeling and vector autoregression techniques to understand the dynamic effects of global crisis shocks on Indian industry and trade. Changes in trade composition are positively associated with changes in manufacturing composition in India, controlling for other variables. However, there is no strong indication that Indian industry has been severely harmed by the fall in demand in crisis-affected advanced economies such as the United States, the European Union, and Japan, holding other things constant.india trade industry; indian industry; india manufacturing sector; india external trade; global economic crisis
Vertical technology transfer and the implications of patent protection
Significant amount of vertical technology transfer occurs between developed and developing country firms, yet the literature on intellectual property rights did not pay much attention to this aspect. We show that whether or not the incumbent and the entrant final goods producers are from the same developed country, patent protection in the developing country raises developed-country welfare if (i) patent protection in the developing country deters entry in the final goods market, (ii) the marginal cost difference between the incumbent and the entrant final goods producers is sufficiently small, and (iii) the marginal cost difference between the incumbent and the entrant developing-country firms is sufficiently high.Entry deterrence; Patent; Vertical technology transfer; Welfare
Coupling of spontaneous emission from GaN/AlN quantum dots into silver surface plasmons
We have demonstrated surface-plasmon induced change in spontaneous emission
rate in the ultraviolet regime at ~ 375-380 nm, using AlN/GaN quantum dots
(QD). Using time-resolved and continuous-wave photoluminescence measurements,
the recombination rate in AlN/GaN QD is shown to be enhanced when spontaneous
emission is resonantly coupled to a metal-surface plasmon mode. The exciton
recombination process via Ag-surface plasmon modes is observed to be as much as
3-7 times faster than in normal QD spontaneous emission and depends strongly on
the emission wavelength and silver thickness.Comment: 11 pages, 4 figure
Maximally -extended super-BMS algebras and Generalized 3D Gravity Solutions
We consider the maximal extended supergravity theory in 3
dimensions with fermionic generators transforming under real but non
necessarily irreducible representations of the internal algebra. We obtain the
symmetry algebra at null infinity preserving boundary conditions of
asymptotically flat solutions, i.e. the maximal extended
super-BMS algebra, which possesses non-linear correction in the
anti-commutators of supercharges. We present the supersymmetric energy bound
and derive the explicit form of the asymptotic Killing spinors. We also find
the most generic circular symmetric ground state of the theory, which
corresponds to a non-supersymmetric cosmological solutions and derive their
entropy.Comment: 29+1 pages, typos correcte
