The cosmological constant problem is seen as a symptom of the ambiguity of the Riemann curvature in general relativity. The solution of that ambiguity provided by Nash's theorem on gravitational perturbations along extra dimensions eliminate the direct comparison between the vacuum energy density and Einstein's cosmological constant, besides being compatible with the formation of structures and...

in Pakistan have repeatedly been involved in major terrorist incidents throughout the world, such as the September 11, 2001, attacks on New York and Washington and the 2005 London subway bombings.1 They regularly strike government, coalition, and civilian targets in Afghanistan, hampering efforts to stabilize the country. Also, they frequently target India, threatening to incite an Indo-Pakista...

Linguists use phylogenetic methods to build evolutionary trees of languages given lexical, phonological, and morphological data. Perfect phylogeny is too restrictive to explain most data sets. Conservative Dollo phylogeny is more permissive, and has been used in biological applications. We propose the use of conservative Dollo phylogeny as an alternative or complementary approach for linguistic...

“Speech banana” is a banana-shaped plot of speech power distribution. It shows speech sounds spoken with normal loudness in terms of frequency and intensity level. Speech bananas have been mainly proposed for Indo-European languages. This work describes an ongoing work of constructing a speech banana for Thai, a Non-Indo-European language. Speech materials are taken from 11 Thais (males and fem...

The impacts of the Indonesian Throughflow (ITF) on the tropical Indo–Pacific climate, particularly on the character of interannual variability, are explored using a coupled general circulation model (CGCM). A pair of CGCM experiments—a control experiment with an open ITF and a perturbation experiment in which the ITF is artificially closed—is integrated for 200 model years, with the 1990 values...

The population of Trinidad and Tobago is composed mainly of people of East Indian (Indo-Trinidadians) and African (Afro-Trinidadians) ancestry. Differences in alcoholism rates exist between these two ethnic groups, and researchers have investigated whether these differences can be explained in part by variations in the genes encoding the alcohol-metabolizing enzymes alcohol dehydrogenase (ADH) ...
