Suppression of stimulated brillouin scattering in higher-order-mode optical fiber amplifiers
An hom-based optical fiber amplifier is selectively doped within its core region to minimize the presence of dopants in those portions of the core where the unwanted lower-order modes (particularly, the fundamental mode) of the signal reside. The reduction (elimination) of the gain medium from these portions of the core minimizes (perhaps to the point of elimination) limits the amount of amplification impressed upon the backward-propagating stokes wave.

Copy number detection and methods
Described herein are methods of measuring, in a genomic sample from an individual, the relative frequency of a target sequence (that is, its copy number) with respect to a control sequence of known copy number at a different genomic locus in the same genome, wherein the target and control sequences differ by at least one single nucleotide variation (snv). These methods involve both the target sequence and the control sequence in a single reaction/container, using a pair of primers that prime amplification of both the target sequence and the control sequence, or a single downstream primer and two upstream primers (that differs only at the position of the snv between the target and control sequences), and measuring the abundance of each of the target sequence and the control sequence using snv-specific labeled probes or primers, or a melting curve analysis that distinguishes between the amplified control and target sequences.
