Radiowave absorption and connected phenomena in the auroral zone, in relation to primary particles and magnetosphere
No full textUAG R-168, Final Report. Preface excerpt: This report presents the results of a program intended to explore the relations between ground-based auroral observations at College and satellite-based observations of the auroral primary particles, the radiation belt and the magnetosphere. The radio wave absorption aspects of the auroral phenomenon were given major emphasis.The investigation was financially supported by the National Science Foundation Grant GP 2779.Preface – Ch.1.

On Lipschitzian Q0 and INS matrices
No full textAbstractA problem posed by Murthy, Parthasarathy, and Sriparna is settled in this note, viz., a nondegenerate matrix satisfying Property (∗∗) introduced by Murthy, Parthasarathy, and Sabatini is shown to be a Lipschitizian matrix. The analysis is based on the results recently derived on INS matrices. We also prove that the class INS under the assumption of nondegeneracy is complete
Optimal strategy sets for continuous two-person games
No full textIn the zero-sum (non-zero sum) completely mixed game each player has only one optimal (equilibrium) strategy (Parthasarathy and Raghavan, 1971). It is known that even for a three person completely mixed finite game the equilibrium set may contain more than one point (Chin, Parthasarathy and Raghavan, 1974). For continuous two person zero-sum games, it is known that there can be more than one optimal strategy even if the game is completely mixed
C4-H indole functionalisation : precedent and prospects
No full textC4-decorated indoles feature in a plethora of bioactive and functional compounds of importance to natural product synthesis, material sciences, as well as crop protection and pharmaceutical industries. Traditionally, their syntheses largely involved harsh stoichiometric metalations and radical reactions. However, transition metal catalysed C-H activation has recently evolved into a powerful strategy for the late-stage diversification of indoles at the C4-H position. Modern photoredox, enzymatic and precious transition metal catalysis represent the key stimuli for developing challenging C-C and C-Het bond forming transformations under mild reaction conditions. Herein, we discuss the evolution and application of these methods for the step-economical transformations of otherwise inert C4-H bonds up to December 2017
From quantum stochastic differential equations to Gisin-Percival state diffusion
No full textStarting from the quantum stochastic differential equations of Hudson and Parthasarathy Commun. Math. Phys. 93, 301 (1984) and exploiting the Wiener-Itô-Segal isomorphism between the boson Fock reservoir space �(L2(�+)�(�n��n)) and the Hilbert space L2(μ), where μ is the Wiener probability measure of a complex n-dimensional vector-valued standard Brownian motion (B(t),t�0), we derive a non-linear stochastic Schrödinger equation describing a classical diffusion of states of a quantum system, driven by the Brownian motion B. Changing this Brownian motion by an appropriate Girsanov transformation, we arrive at the Gisin-Percival state diffusion equation N. Gisin and J. Percival, J. Phys. A 167, 315 (1992). This approach also yields an explicit solution of the Gisin-Percival equation, in terms of the Hudson-Parthasarathy unitary process and a randomized Weyl displacement process. Irreversible dynamics of system density operators described by the well-known Gorini-Kossakowski-Sudarshan-Lindblad master equation is unraveled by coarse-graining over the Gisin-Percival quantum state trajectories. © 2017 Author(s)

Coauthor prediction for junior researchers
No full textResearch collaboration can bring in different perspectives and generate more productive results. However, finding an appropriate collaborator can be difficult due to the lacking of sufficient information. Link prediction is a related technique for collaborator discovery; but its focus has been mostly on the core authors who have relatively more publications. We argue that junior researchers actually need more help in finding collaborators. Thus, in this paper, we focus on coauthor prediction for junior researchers. Most of the previous works on coauthor prediction considered global network feature and local network feature separately, or tried to combine local network feature and content feature. But we found a significant improvement by simply combing local network feature and global network feature. We further developed a regularization based approach to incorporate multiple features simultaneously. Experimental results demonstrated that this approach outperformed the simple linear combination of multiple features. We further showed that content features, which were proved to be useful in link prediction, can be easily integrated into our regularization approach. © 2013 Springer-Verlag
