We present details of the analytic computation of the spectrum of lowest spin glueballs in pure Yang-Mills theory in 2+1 dimensions. The new ingredient is provided by the conjectured new nontrivial expression for the ...

Whether biological diversity within communities is limited by local interactions or regional species pools remains an important question in ecology. In this paper, we investigate how an experimentally applied tree-harvesting ...

People often ask how long humankind has to solve the issue of global heating, and the answer provided may be 10 years, 20 years, 50 years, etc. This gives humans the false assurance that the global warming is not a problem ...

We analyze the one loop corrections to leptonic W and Z decays in an R-parity violating extension to the minimal supersymmetric standard model. We find that lepton universality violation in the Z line-shape variables alone ...

We study constraints on type-II two-Higgs-doublet models at large tan beta from CERN LEP and SLD Z-pole data and from lepton universality violation in W decay. We perform a global fit and find that, in the context of Z ...

Plants are under siege from a diversity of enemies that consume both leaf and floral parts. Plants resist damage to leaves in a variety of ways, and we now have a rich literature documenting how plants defend themselves ...

We discuss the issue of parity violation in quantum gravity. In particular, we study the coupling of fermionic degrees of freedom in the presence of torsion and the physical meaning of the Immirzi parameter from the viewpoint ...

We report the first measurement of an angular correlation parameter in neutron beta decay using polarized ultracold neutrons (UCN). We utilize UCN with energies below about 200 neV, which we guide and store for similar to ...

For most of the past 2 million years, the dominant view has been that resources are limited. However, more recently some economists have become wildly optimistic about natural resource depletion. Some view the human economy ...

The Industrial Age has been made possible by cheap, abundant fossil fuels, primarily petroleum and coal. The life expectancy of an industrial civilization is about 100 years. Some forecasts estimate the critical period of ...
