The ultra-violet spectrum of [alpha] Cygni

The Abiotic Action of Ultra-violet Light

Typhoid bacilli are about one two-hundredth as sensitive to ultraviolet light of wave-lengths 2100 to 2800 Angström units as is the photographic plate. This sensitivity then falls off, decreasing rapidly to almost zero sensitivity at about 2970, the beginning of the sun's spectrum.

Ultra-violet Finite Noncommutative Theories

We establish the ultraviolet finiteness of various classes of noncommutative gauge theories.

Ultra-Violet Behavior of Bosonic Quantum Membranes

We treat the action for a bosonic membrane as a sigma model, and then compute quantum corrections by integrating out higher membrane modes. As in string theory, where the equations of motion of Einstein’s theory emerges by setting β = 0, we find that, with certain assumptions, we can recover the equations of motion for the background fields, i.e. Rμν +(1/4)FμαβγμF αβγ ν = 0 and DFαβγ = 0. for t...
