Is Absorption a Consequence of Unitarity ?
Absorptive corrections to scattering and production in a family of explicitly unitary models is studied. We find that in a particular model in which quantum number constraints are ignored, all the results concerning absorptive corrections found in the Reggeon calculus model of Abramovskii, Kancheli, and Gribov are reproduced. In extended models, however, the effects due to quantum numbers and/o...
متن کاملIs “Loss of Control” Always a Consequence of Addiction?
Research into addiction has a long history although there has always been much debate as to what the key components of addiction are. Irrespective of the theory and model of addiction, most theorizing on addiction tends to assume (implicitly or explicitly) that “loss of control” is central (if not fundamental) to addiction. This short paper challenges such notions by arguing that there are a mi...
متن کاملFormation of GW bodies is a consequence of microRNA genesis.
GW bodies (GWBs), or mammalian P bodies, proposed to be involved in messenger RNA storage and/or degradation, have recently been linked to RNA interference and microRNA (miRNA) processing. We report that endogenous let-7 miRNA co-precipitates with the GW182 protein complex. In addition, knockdown of two proteins, Drosha and its protein partner DGCR8, which are vital to the generation of mature ...
متن کاملWhat is Tarski's common concept of consequence?
In 1936 Tarski sketched a rigorous definition of the concept of logical consequence which, he claimed, agreed quite well with common usage—or, as he also said, with the common concept of consequence. Commentators of Tarski’s paper have usually been elusive as to what this common concept is. However, being clear on this issue is important to decide whether Tarski’s definition failed (as Etchemen...
متن کاملCancellation of photoinduced absorption in metal nanoparticle composites through a counterintuitive consequence of local field effects
By applying the Maxwell Garnett model to gold nanoparticles in water we deduce a value of Im xi (3) 5 1.1 3 1027 esu for the imaginary part of the cubic susceptibility for gold corresponding to a Fermi smearing mechanism. We also demonstrate a sign reversal in the nonlinear absorption for gold particles in 1, 18, 3, 3, 38, 38-hexamethylindotricarbocyanine iodide. Although the imaginary part of ...
