Relations between some analytic representations of one-loop scalar integrals [PDF]

, 1994
We compare several parametrized analytic expressions for an arbitrary off-shell one-loop $n$-point function in scalar field theory in $D$-dimensional space-time, and show their equivalence both directly and through path-integral methods.Comment: 12 pages,

Superstring Gravitational Wave Backgrounds with Spacetime Supersymmetry

, 1994
We analyse the stringy gravitational wave background based on the current algebra $E^{c}_{2}$. We determine its exact spectrum and construct the modular invariant vacuum energy. The corresponding N=1 extension is also constructed.

Mutagenesis of p22 phox Histidine 94

Journal of Biological Chemistry, 2002
The NADPH oxidase is a multicomponent enzyme that transfers electrons from NADPH to O2 to generate superoxide (O 2 ⨪ ), the precursor of microbicidal oxygen species that play an important role in host defense.

Genetic parameters for medullated fiber and its relationship with other productive traits in alpacas

Animal, 2019
The alpaca fiber diameter (FD) varies from 18 to 36 μm, being the finer fiber categories highly appreciated. However, the alpaca fiber presents some limitations in the textile industry due to the high incidence of fiber medullation and diameter ...

Large N Phase Transitions and Multi-Critical Behaviour in Generalized 2D QCD

, 1994
Using matrix model techniques we investigate the large N limit of generalized 2D Yang-Mills theory. The model has a very rich phase structure. It exhibits multi-critical behavior and reveals a third order phase transitions at all genera besides {\it ...
