We analyze the classical stable configurations of an extra-dimensional gauge theory, in which the extra dimensions are compactified on a torus. Depending on the particular choice of gauge group and the number of extra dimensions, the classical vacua compatible with four-dimensional Poincaré invariance and zero instanton number may have zero energy. For SU(N) on a two-dimensional torus, we find ...

Lathrolestesivoriensis sp. n. is described from Côte d'Ivoire. This is the second record of the genus from the Afrotropical region and the first record of the genus and the subfamily for the country. Illustrated re-description of Lathrolestesruwenzoricus (Benoit, 1955) is also provided.

Recently five dimensional supersymmetric models with a Scherk-Schwarz supersymmetry breaking and a localized superpotential on a fixed-point have been constructed to yield a definite prediction for the Higgs mass. We examine this issue in detail and show that the finite one loop correction and the definite prediction for the Higgs mass are just a consequence of a special “Kaluza-Klein regulariz...

The Otodontidae include some of the largest sharks to ever live in the world's oceans (i.e., Carcharocles megalodon). Here we report on Paleocene and Eocene occurrences of Otodus obliquus and Carcharocles auriculatus from Alabama, USA. Teeth of Otodus are rarely encountered in the Gulf Coastal Plain and this report is one of the first records for Alabama. Carcharocles auriculatus is more common...

A new species of the genus Psithyristria Stål, 1870, Psithyristria ridibunda sp. nov., is described from Quezon, Luzon, Philippines. The new species is very similar to Psithyristria incredibilis Lee & Hill, 2010, but the cubital cell is distinctly larger than the radial cell and the medial branch of the uncal lobe is much shorter than the lateral branch and has two tiny apical spines. Psithyris...

This paper conducts empirical investigation on the relationship between exchange rate and inflation targeting regime in the three developed and three emerging Asian economies that have adopted inflation targeting (IT) regime. Using a multivariate GARCH model under BEKK specification, we investigate if exchange rate affect the performance of IT and the performance of IT is compared between Asian...

Only three mutant cystic fibrosis (CF) alleles have to date been established as conferring a dominant mild effect on affected subjects who are compound heterozygotes. We now add a fourth, P67L, which occurs on about 1.4% of Scottish CF chromosomes. Among 13 patients (12 unrelated) with this allele, the average age at diagnosis was 22.5 +/- 11.3 years. None of the cases had consistently raised s...

We provide accounts of four species of Synelmis Chamberlin, 1919 (Annelida: Phyllodocida: Pilargidae) from Australian and adjacent seas, including one new species, S. sergi sp. nov. The only previous, positively identified, record of a Synelmis species in the region, S. gibbsi Salazar-Vallejo, 2003, has been checked and the specimens re-identified here as S. knoxi Glasby, 2003, which extends th...

Soil and litter arthropods represent a large proportion of tropical biodiversity and perform important ecosystem functions, but little is known about the efficacy of different tropical forest restoration strategies in facilitating their recovery in degraded habitats. We sampled arthropods in four 7- to 8-year-old restoration treatments and in nearby reference forests. Sampling was conducted dur...
