Spanner of an undirected graph G = (V, E) is a sub graph which is sparse and yet preserves all-pairs distances approximately. More formally, a spanner with stretch t ∈ N is a subgraph (V, ES), ES ⊆ E such that the distance between any two vertices in the subgraph is at most t times their distance in G. We present two randomized algorithms for maintaining a sparse t-spanner of an undirected unwe...

Many neurosurgery patients may have unrecognized diabetes or may develop stress-related hyperglycemia in the perioperative period. Diabetes patients have a higher perioperative risk of complications and have longer hospital stays than individuals without diabetes. Maintenance of euglycemia using intensive insulin therapy (IIT) continues to be investigated as a therapeutic tool to decrease morbi...

We develop a heterogeneous firm intra-industry trade model in which countries are asymmetric in both technology and size. In our model the productivity gaps and levels across countries are jointly determined by technological asymmetry and trade barriers. By assuming symmetry across countries, Melitz (2003)shows that increased exposure to IIT raise aggregate productivity for all countries via re...

My father was a Professor of Physics at the Indian Institute of Technology (IIT) Kharagpur, a world renowned engineering school in Eastern India that has produced many famous scientists, engineers and entrepreneurs. Growing up on IIT campus, I felt that the only subjects people studied were either engineering or one of the physical sciences. My mother, who had a degree in nutrition, never worke...

This paper analyzes the theoretical and empirical relationship between intraindustry trade flows (IIT) in manufactures and technical change for the Colombian manufacturing industry during 1970-1995 period. A general estimating equation for sources of change of the equilibrium number of varieties, in which TFP growth is one of its components, is derived from the basic model of trade in different...

Myron Goldsmith (1918-96) was a unique figure in the development of tall building design. He successfully blended the roles of architect, engineer and teacher throughout his tenure at Skidmore Owings and Merrill (SOM) and in the Department of Architecture at the Illinois Institute of Technology (IIT). Indeed, many of the projects supervised by Goldsmith and his colleagues, to include the pre-em...

The psychological state elicited by the classic psychedelics drugs, such as LSD and psilocybin, is one of the most fascinating and yet least understood states of consciousness. However, with the advent of modern functional neuroimaging techniques, the effect of these drugs on neural activity is now being revealed, although many of the varied phenomenological features of the psychedelic state re...

This paper critically assesses the anti-functionalist stance on consciousness adopted by certain advocates of integrated information theory (IIT), a corollary of which is that human-level artificial intelligence implemented on conventional computing hardware is necessarily not conscious. The critique draws on variations of a well-known gradual neuronal replacement thought experiment, as well as...

Information Integration Theory (IIT) is concerned with how people combine information into an overall judgment. A method is hereby presented to perform Functional Measurement (FM) experiments, the methodological counterpart of IIT, on the Web. In a comparison of Web-based FM experiments, face-to-face experiments, and computer-based experiments in the lab it is found that the computer-based meth...

An approach for optimizing computer-generated holograms is discussed. The approach can be summarized most generally as hierarchically designing a number of holograms to add up coherently to a single desired reconstruction. In the case of binary holograms, this approach results in the interlacing technique (IT) and the iterative interlacing technique (IIT). In the IT, a number of subholograms ar...
