Anil Kumar Lala (1950–2004)
No full textAnil Kumar Lala, Professor of Chemistry at the Indian Institute of Technology (IIT), Bombay died on 17 July 2004, following a stroke that he suffered three weeks earlier. Born on 13 January 1950, Lala did his B Sc from Delhi University and obtained his Ph D in 1974,working under the supervision of A. B. Kulkarni at Bombay University. His doctoral work was in the area of steroid chemistry, introducing him to the areas of NMR spectroscopy and mass spectrometry. Following a year at the Central Drug Research Institute in Lucknow, Lala moved to the State University of Ghent, Belgium,to work with Marc Anteunis. I first saw his name in a scientific publication,when the conformational analysis of methionine enkephalin, then recently discovered as the endogeneous ligand for the opioid receptor, was described by the French and Belgian groups, with Lala as a co-author (Roques, B. P. et al., Nature,1976, 262, 778). In 1976, he moved to Harvard University to work with Konrad Bloch and it is this period, which sparked his lifelong interest in membranes, specifically lipid–protein interactions. Lala joined the chemistry department at IIT,Mumbai in 1979 and it was here that he spent the remaining 25 years of his scientific career

Assessing ice sheet models against the landform record: The Likelihood of Accordant Lineations Analysis (LALA) tool
Full text linkPalaeo-ice sheets leave behind a rich database regarding their past behaviour, recorded in the landscape in the form of glacial geomorphology. The most numerous landform created by these ice sheets are subglacial lineations, which generate snapshots of the direction of ice flow at fixed (yet typically unknown) points in time. Despite their relative density within the landform record, the information provided by subglacial lineations is currently underutilised in tests of numerical ice sheet models. To some extent, this is a consequence of ongoing debate regarding lineation formation, but predominantly, it reflects the lack of rigorous model-data comparison techniques that would enable lineation information to be properly integrated. Here, we present the Likelihood of Accordant Lineations Analysis (LALA) tool. LALA provides a statistically rigorous measure of the log-likelihood of a supplied ice sheet simulation through comparison of simulation output with both the location and direction of observed lineations. Given an ensemble of ice sheet simulations, LALA provides a formal, and statistically underpinned, quantitative assessment of each simulation's quality-of-fit to mapped lineations. This enables a comparison of each simulation's relative plausibility, including identification of the most likely ice sheet simulations amongst the ensemble. This is achieved by modelling lineation formation as a marked Poisson point process and comparison of observed to modelled flow directions using the von Mises distribution. LALA is flexible—users can adapt parameters to account for differing assumptions regarding lineation formation, and for variations in the level of precision required for differing model-data comparison experiments. We provide guidelines and rationale for assigning parameter values, including an assessment of the variability between users when mapping lineations. Finally, we demonstrate the utility of LALA through application to an ensemble of simulations of the last British-Irish Ice Sheet. This comparison highlights the benefits of LALA over previous tools and demonstrates some of the considerations of experimental design required when identifying the fit between ice sheet model simulations and the landform record.</p

MeSH term explosion and author rank improve expert recommendations
Full text linkInformation overload is an often-cited phenomenon that reduces the productivity, efficiency and efficacy of scientists. One challenge for scientists is to find appropriate collaborators in their research. The literature describes various solutions to the problem of expertise location, but most current approaches do not appear to be very suitable for expert recommendations in biomedical research. In this study, we present the development and initial evaluation of a vector space model-based algorithm to calculate researcher similarity using four inputs: 1) MeSH terms of publications; 2) MeSH terms and author rank; 3) exploded MeSH terms; and 4) exploded MeSH terms and author rank. We developed and evaluated the algorithm using a data set of 17,525 authors and their 22,542 papers. On average, our algorithms correctly predicted 2.5 of the top 5/10 coauthors of individual scientists. Exploded MeSH and author rank outperformed all other algorithms in accuracy, followed closely by MeSH and author rank. Our results show that the accuracy of MeSH term-based matching can be enhanced with other metadata such as author rank
