We point out a non-trivial connection between the model proposed by Hořava and Keeler as a candidate for noncritical M -theory and the Gross-Neveu model with fermionic fields obeying periodic boundary conditions in 2+ 1 dimensions. Specifically, the vacuum energy of the former is identified with the large-N free-energy of the latter up to an overall constant. This identification involves an app...

This study evaluated the reliability and validity of a Belgian computerized questionnaire to measure at intake. A total of 86 adults completed a 48-item computerized fat intake questionnaire, subseuently kept a 7-day diet record, and finally completed the questionnaire again. For validity, a Pearson orrelation of 0.67 for total fat intake and of 0.60 for percent energy from fat were found betwe...

Abstract: Self-gravitating Bose-Einstein condensates (BEC) have been proposed in various astrophysical contexts, including Bose-stars and BEC dark matter halos. These systems are described by a combination of the Gross-Pitaevskii and Poisson equations (the GPP system). In the analysis of these hypothetical objects, the Thomas-Fermi (TF) approximation is widely used. This approximation is based ...

effects of supplemental phytase and xylanase in a corn-soybean meal based diet containing 250 g/kg wheat bran, were investigated. on broiler performance and phosphorus degradability and nitrogen digestibility. phytase (500 and 1000 ftu) and xylanase (2700 and 5400 exu) individually and in combination were added to the basal diet and given to 6 replicate groups (4 birds per replicate). at 21...

Divisia index A method of aggregation used in economics that permits variable substitution among material types without imposing a priori restrictions on the degree of substitution. emergy The quantity of solar energy used directly and indirectly to produce a natural resource, good, or service. energy quality The relative economic usefulness per heat equivalent unit of different fuels and elect...

This study aimed to discuss the energy budget of Elliot's pheasant Syrmaticus ellioti in different seasons, with life and health, good growth and normal digestion of Elliot's pheasant as the tested objects, The energy budget of Elliot's pheasant was measured by daily collection of the trial pheasants' excrement in the biological garden of Guangxi Normal University from March 2011 to February 20...

The ground state properties of interacting Bose gases in external potentials, as considered in recent experiments, are usually described by means of the Gross-Pitaevskii energy functional. We present here the rst proof of the asymptotic exactness of this approximation for the ground state energy and particle density of a dilute Bose gas with a positive interaction.
