Bhashaposhini Suchika (1977 –1992) [à´à´¾à´·à´¾à´ªàµ‹à´·à´¿à´£à´¿ സൂചിക 1971-1992]
The journal Bhashaposhini is an authentic source for stdueis and research in areas of Malayalam literature, history and culture. It started publication in 1987 and after completion of 49 volumes ceased publication in 1942. It was revived from 1977 as a bimonthly. The present work is an index to the articles published in Bhashaposhini from 1977 to 1992 (New Volumes 1-16). Being an authentic knowledge source for regional studies and research, the need for an index to Bhashaposhini was strongly felt. The index has been classified under two major heads – Literature and Science. All articles other than literature are grouped under science
Popular matchings
We consider the problem of matching a set of applicants to a set of posts, where each applicant has a preference list, ranking a non-empty subset of posts in order of preference, possibly involving ties. We say that a matching M is popular if there is no matching M' such that the number of applicants preferring M' to M exceeds the number of applicants preferring M to M'. In this paper, we give the first polynomial-time algorithms to determine if an instance admits a popular matching, and to find a largest such matching, if one exists. For the special case in which every preference list is strictly ordered (i.e. contains no ties), we give an O(n+m) time algorithm, where n is the total number of applicants and posts, and m is the total length of all the preference lists. For the general case in which preference lists may contain ties, we give an O(√nm) time algorithm, and show that the problem has equivalent time complexity to the maximum-cardinality bipartite matching problem
Searching for an anomalous coupling via single top quark production at a collider
We investigate the potential of a high-energy collider to
detect an anomalous coupling from observation of the reaction
, , where or . We find that with
-tagging and suitable kinematic cuts this process should be observable if
the anomalous coupling is no less than about 0.05/TeV, where
is the scale of new physics associated with the anomalous
interaction. This improves upon the bound possible from observation of top
decays at the Tevatron.Comment: 13 pages, RevTeX, 1 PS figur
A Hierarchical Bayesian Model of Pitch Framing
Since the advent of high-resolution pitch tracking data (PITCHf/x), many in
the sabermetrics community have attempted to quantify a Major League Baseball
catcher's ability to "frame" a pitch (i.e. increase the chance that a pitch is
called as a strike). Especially in the last three years, there has been an
explosion of interest in the "art of pitch framing" in the popular press as
well as signs that teams are considering framing when making roster decisions.
We introduce a Bayesian hierarchical model to estimate each umpire's
probability of calling a strike, adjusting for pitch participants, pitch
location, and contextual information like the count. Using our model, we can
estimate each catcher's effect on an umpire's chance of calling a strike.We are
then able to translate these estimated effects into average runs saved across a
season. We also introduce a new metric, analogous to Jensen, Shirley, and
Wyner's Spatially Aggregate Fielding Evaluation metric, which provides a more
honest assessment of the impact of framing
Present Risk, Future Risk Or No Risk - Measuring and Predicting Perceptions of Health Risks of a Hazardous Waste Landfill
Given that perceived risk is multidimensional, the authors seek better understanding by focusing on health risks and, more particularly, on their temporality. In this way, they attempt to measure more meaningfully psychological influences on risk perceptions
