India has one of the largest assemblages of tropical biodiversity, with its unique floristic composition of endemic species. However, current forest cover assessment is performed via satellite-based forest surveys, which have many limitations. The present study, which was performed in the Eastern Ghats, analysed the satellite-based inventory provided by forest surveys and inferred from the resu...

We study the Standard Model prediction for the mass difference between the two neutral D meson mass eigenstates, ∆m. We derive a dispersion relation based on heavy quark effective theory that relates ∆m to an integral of the width difference of heavy mesons, ∆Γ, over varying values of the heavy meson mass. Modeling the mD-dependence of certain D decay partial widths, we investigate the effects ...

increasing urbanisation and industrialisation have led to a dramatic reduction in forest area, and now only culturally protected remnants of natural forests and some new plantations remain in most areas of the north of iran. to investigate the status of the chemical and physical characteristics of soil under these remnant forests and assess the possible impacts of reforestation on soil properti...

Development and change in forest communities are strongly influenced by plant-soil interactions. The primary objective of this paper was to identify how forest soil characteristics vary along gradients of forest community composition in aspen-conifer forests to better understand the relationship between forest vegetation characteristics and soil processes. The study was conducted on the Fishlak...

Tropical forests are being rapidly altered by logging, and cleared for agriculture. Understanding the effects of these land use changes on soil fungi, which play vital roles in the soil ecosystem functioning and services, is a major conservation frontier. Using 454-pyrosequencing of the ITS1 region of extracted soil DNA, we compared communities of soil fungi between unlogged, once-logged, and t...

An ultraviolet regularization and renormalization procedure of light-cone perturbation theory, which is suitable for a numerical application is discussed. The fourth order correction to the anomalous magnetic moment of the electron in the light-cone gauge is computed. Several regularizations of the associated light-cone gauge singularity are explored. Local counterterms are constructed to remov...

We discuss the effects of instantons in partially broken gauge groups on the lowenergy effective gauge theory. Such effects arise when some of the instantons of the original gauge group G are no longer contained in (or can not be gauge rotated into) the unbroken group H. In cases of simple G and H, a good indicator for the existence of such instantons is the “index of embedding.” However, in th...

The rates and corresponding jet distributions for the decay 2 t b&g and the process e+e+ tfg may be sensitive to anomalous dipole-like couplings of heavy quarks to the photon and 2. In the b-quark case, after updating our previous analysis on the constraints imposed by current experiments on Zbb anomalous couplings, we show that the variation of these couplings within their presently allowed ra...
