Fluoride glasses show great promise for mid-IR fiber-based applications. Their brittleness and low glass transition temperature have thus far been obstacles towards obtaining low-loss fused components. Here, we suggest a simple method to measure glass viscosity over a range of process temperatures of interest for fused coupler fabrication.

Xanthomonas vasicola was identified as the causal agent of this disease. A multilocus sequence alignment of six housekeeping genes and comparison of average nucleotide identity from draft genome sequence were used to confirm phylogenetic relationships and classification of this bacteria relative to other X.

To curb this trend, it is critical to identify children with factors that increase susceptibility to developing pediatric malignant melanoma (MM). Risk reduction is a complex process that involves detecting the rudiments of melanocytic tumors at the precancer stage, altering attitudes toward sunlight and suntans, and in incidence.
